Wasserstand-messvorrichtung für pflanzengefässe

RST the available invention refers to a device for the determination of the water level in accordance with generic term of the requirement 1. Indicators of change of landing on water or humidity measuring instruments are necessary, in order to avoid a Übergie.ssen or a dry of plants in plant containers. In earth cultures with Ubertöpfen also the danger of the so-called pilot wetness exists: For lack of a possibility of controlling the water level too early one after-pours, so that the plant container is located permanently in the water. The plants require however that the store of water is regularly used up and the lowest planting substrate layers are not however impregnated if necessary still damp. The pilot wetness causes a rot of the roots, in particular the most sensitive and being rooted hurry most valuable for the plant finally, and dying roots. The growth of the plant is impaired accordingly, whereby the plant can even die. In it cultures are enclosed in earth up to hydraulic culture. A such water level indicator is well-known from the CH-570 754. The well-known water level indicators have however the disadvantage that they do not permit it in principle to determine the water level up to the ground of the plant container or up to the ground of the reductor or Ubertopfes. The Wasserstandsmesser with float have beyond that above an opening, by the planting substrate (e.g. earth) or to arrive it knows other impurities the inside the Schwimmergehäuses whereby this is prevented from its function. Besides also a danger exists; that Pfianzsubstrat and roots from downside ago into the Schwimmergehäuse penetrate and the function impair or it can leaky Schwimmerkugeln with water fill and the Wasserstandsmesser thereby become function unfit. Opposite a task of the invention consists of indicating a water level measuring device for plant containers with which the danger of a function implication is substantially decreased by contamination. Another task of the invention consists of indicating a water level measuring device for plant containers which permit a water level regulation up to the ground of the collecting basin. A device, which fulfills at least the task only specified, is indicated in the requirement 1. The further requirements indicate preferential execution forms. The water level measuring device, or briefly the level gauge, consists accordingly essentially of a mounting plate or a guidance and a measuring tube. The measuring tube can be lowered by the mounting plate through up to the ground of the water collecting basin. The water level in the measuring tube corresponds thereby exactly to the surrounding level of the water in the plant container and/or. the surrounding over pot, so far available. Now the upper end of the measuring tube singleproves locked with a finger, then this level in the measuring tube remains when pulling out and can be read off. The measuring tube can exhibit additionally markings, which facilitate it to determine whether the water level is in a permitted range. The invention is continued to describe with remark examples with reference to figures. Fig. 1 shows a first execution form of a level gauge according to invention; Fig. a second execution form of the level gauge shows 2; Fig. 3 shows a profile by the upper end of a first variant of a guide tube; Fig. 4 shows a profile by a second variant of a guide tube; Fig. 5 shows a profile by a third variant of a guide tube; Fig. a side view shows 6 to a variant of an owner with extended extension; ss Fig. an opinion from above shows 7 to another variant of an owner; Fig. a side view of a variant of an owner extension shows 8; and Fig. 9 a partial section by a plant container with a further execution form of the level gauge. Fig. 1 shows a cut by a Pflanzeng.efäss 1 with planting substrate 2 and a plant 3. The plant container 1 is in a Ubertopf 5, in which still another water catch pan 6 under the plant container 1 is on-regulatory. Often however without the water catch pan (reductor) one does to 6, if the Ubertopf 5 can take over this task. lo into the planting substrate 2 the owner 8 of the level gauge is in-rammed. It had in addition a thorn-like extension 10, at whose upper end a laterally which is away tongue 12 is, in which an opening 14 is arranged. By the opening 14 the measuring tube 16 is put through. Obviously it represents thereby no problem, the measuring tube 16 up to the ground of the water catch pan 6 and/or. if such is missing to lower up to the ground of the over pot 5. The water level in the measuring tube 16 agrees so measured of the lower end 17 with high accuracy with the current water level in the plant cultural arrangement 19, without which a dead range is to be considered. For the measurement the upper end of the measuring tube 16 is locked, pulled out at the simplest one with the finger, and the measuring tube 16. Then directly 16 on the water level 23 can be closed over the height of the water level in the measuring tube. For keeping a certain range of the level 23 the measuring tube can exhibit 16 still markings (see below Fig. 9). In order a diagonal would bring in the measuring tube 16 to prevent, is present at or in the opening 14 a guide sleeve 18. Obviously it can be recognized on the one hand very simply, if individual parts of the planting substrate erred into the measuring tube and its function to impair. A cleaning can singleproves via rinsing the measuring tube 16 out to take place. On the other hand, also with presence of substrate particles in the measuring tube 16, the water level in the latter agrees still with the level 23, since the measuring tube 16 is usually continuously in the device and can from there the water level in the measuring tube 16 also with partial blockage to the surrounding water level adjust itself. In Fig. 2 second execution form shown of the invention is for the employment inside a plant container 1 trained. A guide tube 30 in the planting substrate 2, whose inside diameter is larger than the outside diameter of the measuring tube 16, is. The guide tube 30 rises up by the planting substrate 2 and by a drain hole 32 in the ground of the plant container 1 through up to the ground of the water catch pan 6. the measuring tube 16 can thereby by the guide tube 30 problem-free up to the deepest point (here: to the ground of the water catch pan 6), to be lowered and thus as above described the actual water level to be determined. The guide tube 30 can end thereby at one point between drain hole 32 and ground of the catch pan 6. The guide tube 30 can be locked at its upper end with a cover 33, in order to avoid a falling of planting substrate 2 or other breakdown bodies. The guide tube 30 is inserted at the best one with empty plant container 1 and in-given then the planting substrate 2 with plant 3 into the plant container 1. In particular it is problem-free possible to put the guide tube 30 through a drain hole 32. If the guide tube 30 must be introduced later, then it must in a kind drilling procedure by the planting substrate 2 and that more or less seals root work 35 to the ground the 4 of the plant plant 1 to be pushed forward. Finally then also still another drain hole 32 must be met. If necessary it can be sufficient in addition, to penetrate and thus only the water level 23 of the ground of the plant container 1 aüs to determine be able only up to the ground of the Pflanzengef of isses 1. The planting substrate 2 penetrated with boring into the guide tube 30 must be removed thereafter by rinses. In addition a needle from above can be e.g. introduced and water at the lower end the guide tube 30 be injected, whereby in the pipe contained substrate is out-pressed upward. If the guide tube stands out 30 down from the plant container 1, then naturally also a flushing is from top to bottom possible, as the guide tube is withdrawn 30 something and/or. the plant container 1 lo or lifted out from the over pot 5 is tilted. Is in addition, conceivable to provide for boring the guide tube 30 with a kind drilling point which locks the guide tube at the same time during the drilling procedure. The drilling point can serve also to perforate with plant containers made of plastic the ground. The drilling point can be removed, if the guide tube 30 from the plant container 1 out-steps down, in suitable kind e.g. cut off or at a location of fracture bent. Conceivably still different methods are, in order to attach the guide tube 30 with filled plant container 1, e.g. breaking through from downside ago with following rinsing, whereby the search for a drain hole 32 is avoided. Guide tube 30 like also measuring tube 16 can of most diverse materials consist: for the measuring tube 16 naturally transparent materials are recommended such as glass, plexiglass or other plastics, for the guide tube 30 are applicable also stainless metals or clay/tone. The owner 8 can consist of the same materials. A material, which is chemical and physically indifferent, is preferential thus in particular opposite water is inert for owner 8, guide tube 30 and measuring tube 16. The inside diameter of the measuring tube 16 is in such a way however also not selected that capillary forces move still no falsification of the level 23, on the other hand too largely selected, in order to make a safe locking possible with a finger. The inside diameter lies thereby preferentially within the range of approx. 2 mm up to approx. 6 mm. Preferentially the opening 14 in the owner 8 and the guide tube 30 are so far that the measuring tube 16 is loosely in it led, thus e.g. larger with a width around 0.1 mm up to 1 mm than the outside diameter of the measuring tube 16. The figures 3 and 4 show two possibilities, how the guide tube is build upable 30 from segments. The guide tube can be adapted thereby to different plant container heights. In the first variant the segments 37 are generally zylinderisch with precautions (tapered an end of 39, complementary in addition Ausnehmerung 40 at the other end), in order to interconnect the segments. The second variant in accordance with Fig. 4 uses conical segments 38, which can be into one another-placed. Over the taper 42 the overlap of the conical segments can be stopped. The stages 43 during this execution have beside it still another certain Widerhakenwirkung, which embodies and against pulling out secures the guide tube 30 in the surrounding planting substrate. Conceivably is also to make possible a length adjustment of the measuring tube by setting from extensions to e.g. similarly the Fig. 3. However one would be sufficient atmospheric pressure connection necessary, e.g. by a poetry like an O-ring (not represented). Fig. a variant of a guide tube shows 5, with which the exterior surface is provided with a saw tooth profile 45. As is the case for the execution in accordance with Fig. 4 thereby the anchorage in the planting substrate is improved among other things. Fig. a variant of the owner 8, which is characterised by its adjustableness, shows 6. The tongue 12 is designed as border 47, which is adjustable in a guidance 48 on the extension 10 in accordance with arrow 49. In order to avoid an inadvertent shifting of the border 47, RST at the guidance 48 and the border 47 can be trained a curved or toothed profile, in order to cause with shifting the border 47 a rest effect, if the Zahnoder of wave combs one above the other-slides. Fig. a further variant of the owner 8 with two shows 7 or more holes 14. Between the holes 14 are perforations, stamped break lines or other precautions 52, in order to be able to shorten the tongue 12 on the length needed in each case. In addition the part of the tongue 12, which over the necessary hole 14 exceeds, is separated. Thus the tongue 12 can be adapted e.g. to the wall thickness of the plant container similar to the variant described above. An exemplary execution form has an extension with a length of approx. 6 cm (point to surface of the tongue). The tongue exhibits an overall length of approx. 7 cm, the first dividing lines lies with approx. 4 cm, which are remaining dividing lines about evenly between first dividing line and the tongue end distributes. In Fig. it is shown 8 that the extension 10 can be equipped with reinforcement bars 54. In particular, if the extension 10 actually exhibits a flat cross section, such bars are favourable, in order to avoid a bending when a stinging. Beside a flat or circular cross section are a multiplicity of other cross sections of the extension conceivably, e.g. triangular, squarely, generally polygonally (5, 6-eckig etc.), elliptically, oval and combinations from it. As a further further training is in Fig. 6 also an extension 50 of the extension 10 indicated, as their assistance an adjustment to deep planting substrates or a high edge of the plant container beyond the planting substrate to take place can do. Fig. a further remark example of the level gauge according to invention shows 9. In a plant container 1, which is in a over pot 5 with water catch pan 6 (similarly Fig. , a plant 56 with close, buschigem stature is represented to 1 and 2) in this case for the elucidation of the advantages of the further execution forms of the level gauge. The guide tube consists of the jacket pipe 58 and the Verlängerungsrohr 60 arranged adjustably therein. The Verlängerungsrohr exhibits one or more circular bars 62, the jacket pipe 58 in addition complementary in certain distances slots 64. The bars 62 (in Fig. 9: a bar 62) and detents for the Verlängerungsrohr in the jacket pipe 58 define the slots 64. They are in such a way trained that with small energy expenditure the Verlängerungsrohr is adjustable 60 in the jacket pipe 58, it however anyhow not under its dead weight, in addition, usually not during simple, unintentional contact into the jacket pipe 58 drops back. The jacket pipe 58 and the Verlängerungsrohr 60 consist of plastic. The material is in such a way selected that easy sliding of the pipes is into one another ensured and is possible by flexible deformation pulling the rest bars 62 from the slots 64 out with appropriate energy expenditure. The jacket pipe 58 is put in at the lower end into a cap 68. The cap 68, which consists of plastic, fulfills several functions: It filters the water entering from the water catch pan 6 the level gauge by a filter 70 in its ground. For the admission from water to the lower surface of the filter 70 small collections 72 are present, some slight, but sufficient area 74 between cap 68 and catch pan 6 define. The form of the collections or feet 72 can be selected thereby almost at will. Altogether it is to be noted with the fact that for a measurement up to small water levels the distance 76 between the ground of the Wasserauffangwänne 6 and the top side of the ground of the cap 68 is as small as possible zugter value 1 mm or smaller. is. A before those cap 68 prevents a withdrawing of the level gauge upward. For this purpose it has one or more wings 78, which attack in the kind of a Widerhakens at the lower surface of the ground of the plant container 1 and so that a movement upward the cap 68 and thus the jacket pipe 58 prevent. For relief for the user the measuring tube is provided in this execution also with two markings 80, 82. The marking 80 defines a maximum level, which should not be exceeded if possible, the mark 82 a minimum water level, which should not be fallen below. Finally is to be still noticed that the arrangement from jacket pipe 58 and Verlängerungsrohr is applicable 60 owing to the funnel-like extension 84 at the upper end also as a casting assistance, in particular if the measuring tube 16 is pulled out. Favourable way Iässt the level gauge according to invention also at well-known hydraulic cultivated plant containers use themselves. These wise often already at the edge a recessing up, which with a roof with you. .rchführungsöffnung above is covered. Recessing results in an extended area between Ubertopf and plant container, in which a usual Wasserstandsmesser with float can be arranged. Straight ones with small plant containers have these Wasserstandsmesser however a housing also to small diameter, in which the float tilts or wedges for other reasons and indicates from there the water level wrongly. This problem of Nässt however surprisingly simply by the fact separate that the level gauge according to invention is inserted into recessing, whereby their roof works quasi as owner 8. From the preceding description numerous modifications and further educations of the device according to invention are accessible to the specialist, without leaving the scope of protection of the invention, which is defined by the requirements. Conceivable are for example: Combinations of the variant in accordance with figures 3 - other length adjustments of extension 10 or tongue 12 of the owner 8, like a sticking on of tongues of different length or also Aneinanderstecken of tongue segments. Guide tubes and measuring tube with other one than circular cross section, e.g. oval, elliptical, or nierenförmig, e.g. in the case of a close gap between plant container and over pot. The cap exhibits only or two of its precautions (filter, feet and wings). The opening 14 in the owner 8 is far. enough, so that the guide tube is pass throughable 30. By the guide tube it is e.g. guaranteed that the measuring tube between plant container and over pot is importable. Preferentially thereby the guide tube is kept in the opening close, so that a certain clamping effect arises. Instead of the circulating bars 62 and the slots 64 in the jacket pipe it can be fit the two pipes also in such a manner closely into one another that the desired clamping effect arises. A further variant exists in one outside at the Verlängerungsrohr and/or inside at the jacket pipe along running bar. The bar presses on the surface of the other pipe and produces by it the desired clamping effect. Pipes with such collections running in longitudinal direction are inexpensive producible by extruding. These variants grant also the stepless positioning of the Verlängerungsrohrs.
