Переносная микрогэс для работы в естественных потоках воды ручьёв и малых рек

Номер: RU0000206086U1

Полезная модель относится к области производства электрической энергии и служит для преобразования энергии русловых потоков ручьёв и малых рек в электрическую энергию с помощью явления электромагнитной индукции.Детали гидротурбины и полый усечённый конус изготовлены из полимерного композиционного материала, например углепластика. Понтоном служит древесина, прочный пенопласт или герметичный контейнер для деталей и узлов переносной микроГЭС, якорный шест нержавеющий.После выбора подходящего места в русле ручья или реки забивают в дно якорный шест, устраивают понтон с электрическим генератором, соединяют гибким валом вал ротора генератора с гидротурбиной и полым усечённым конусом. Полый усечённый конус создает дополнительное сопротивление прохождению естественного потока воды, а за счёт лопастей турбины, изогнутых по конической винтовой линии, приходит во вращение. Гибкий вал натягивается и удерживает гидротурбину в верхнем, самом быстром, естественном потоке воды, что увеличивает количество вырабатываемой электрической энергии, а отсутствие разбалтывания гидротурбины снижает износ гибкого вала.Разработанная переносная микроГЭС для работы в естественных потоках воды ручьёв и малых рек является лёгкой, переносной, быстро сборно-разборной, вырабатывает повышенное количество электрической энергии, имеет низкий износ гибкого вала. 5 ил.

Burrell compound axial windmill

Номер: US20120061968A1
Автор: Leo LeRoy Burrell
Принадлежит: Individual

A plurality of sail assemblies rotating on their axes rotate about the axis of the windmill hub to rotate a drive shaft. The drive shaft powers a generator, machine, pump, grind-stone or other load the mill is designed to operate. Fabric, metal, or plastic sails are fitted to the frame arms of the sail assembly such that they are releasable under upset conditions such as hurricane or tornado wind velocities or other catastrophic inclusion. In the preferred embodiment of the invention drive shafts housed in tubular metal, plastic, or fiberglass connect the gears of the hub to helical or bevel type right angle gearboxes that rotate the sails at a rate of one time for each two times the hub rotates. A second embodiment of the mill has sprockets at the sail assemblies which drive a sprocket at the hub of the mill. The sprockets are rotated one time for each revolution of the hub sprocket via a roller chain. And the sail assemblies rotate in the same direction as the rotation of the hub sprocket. Other embodiments of the construction of the Burrell pattern Compound Windmill are contemplated. One such embodiment of the mill is mounted in a stream or river, and power is transmitted upward to a platform where a generator or other equipment perform work. Another variation of construction substantially uses parts commonly found in scrapped automobiles—permitting inexpensive windmills in villages in third-world countries where commercial electrical power is either too expensive or not available. Constant Velocity (CV) joints, wheels, alternators, power steering pumps, etc. can be salvaged, and a mill can be designed by a technician trained in that discipline.

The invention consists of a system for converting wind energy (SCEE) into mechanical and then electrical energy. This system (SCEE) is not subject to the theoretical Betz limit (59%). The system (SCEE) has a wheel (F) provided with a series of blades arranged all around it. The wheel (F) rotates in a pivot connection about a fixed axle (L). Set on the axle (L), a support (E) ensures the fastening of the end-plates of a series of double-acting actuating cylinders (D). The rods of the latter are in a ball-jointed connection with the body (A) in order to offer the latter a maximum degree of freedom in space. A rigid arm (C) is set on one side of the wheel (F) and held on the other side, in a pivot connection, on a U-shaped section piece (B). Having a circular satellite motion, the latter rotates with the wheel (F) while sliding over a peripheral region of the body (A). When the wind acts on the body (A), the latter pivots with the section piece (B) and pushes the rods of the actuating cylinders (D). Having a circular satellite motion, the section piece (B) rotates while sliding over a peripheral region of the body (A), thus changing the fulcrum of the moment of the resultant force of the wind (the pivot connection of the section piece (B)) which is applied to the body (A). The rods of the actuating cylinders (D) will consequently be pulled and pushed, while having a cyclical translational motion. Set on the axle (L), a nacelle (J) primarily contains a hydraulic motor (H) and an electric generator (G), which can be coupled via a speed-increasing gear. During the reciprocal motions of the pistons of the actuating cylinders (D), a set of valves ensures a one-way flow of hydraulic fluid in the “go and return” hydraulic circuits, whether by pulling or by pushing.

The invention is a power generator using intermittent fluid flow. The invention facilitates the harnessing of electric power from intermittent wind sources. The apparatus includes panels that are pivotally attached to a frame at a substantially horizontal orientation or are at an acute angle to the horizontal. As wind blows, the panels lift upward relative to the horizontal. Alternatively, the panels may be vertical and attached to an inclined track where the panels move up the track as the wind blows. This motion is transferred to a permanent magnet alternator either via the rotation of a shaft at the pivot point or via a connector rod attached to a leading edge of the panel. The motion may also be transferred by actuating a hydraulic cylinder.

SYSTEM FOR GENERATING ELECTRICAL ENERGY

Номер: US20220173635A1

A system for generating electricity includes a bar and a source of a pressurized fluid. A three-way connection piece has an inlet opening connected to the source through an inlet solenoid valve and a discharge opening connected to a discharge solenoid valve. A connection line connects the three-way connection piece to a working cylinder. A shaft of the working cylinder strikes against the bar causing an oscillating motion. A first and a second rod convert the oscillating motion into a back-and-forth translational motion which a drive means converts into a cyclical drive motion. An apparatus for generating electrical energy is driven by the cyclical drive motion. During operation, the inlet solenoid valve and the discharge solenoid valve are continuously switched from a first working position to a second working position, and vice versa, at a frequency which is identical to the natural frequency of the bar. 111.-.
