Grabbing superficial deposit sampler

Technical Field

The present invention relates to the field of environmental science river, lake, reservoir shallow sediment collecting technology and, in particular to a grabbing superficial sediment sampler.

Background Art

Sediment is river, lake, ocean, reservoir and an important part of the water, it can by precipitation-dissolution, adsorption-desorption various means, such as between the overlying water exchange substance, various pollutants in the water body and the relocation of the plays an important role in seafloor, therefore the deposit monitoring a water environment investigation and research work an important link in. Sediment sample collection is to realize a necessary precondition for deposit monitoring. At present, more commonly used sampling surface sediment sampler is the freshwater mussel type , the main characteristics of the sampler is and problems: 1) for the people on and throwing by means of a sampling device itself is inserted into the weight of the deposit, this kind of sampling mode will make the sampling depth is hard to control, has a certain blindness; 2) through the rope traction and by means of a sampling device for sampling the weight of the opening and the closing of the, this kind of sampler opening/closing control mode often exsisting, in order to cause the drop of the sample in the process of lifting.
