The invention relates to hydropower, particularly to a hydraulic units for the removal energy of a fluid medium, in particular for the energy of rivers, canals, etc.

Known free-threaded hydropower plant [1] containing the blades, mounted on a flexible shaft in the form of a cable connected to the actuator mounted on the support above the water level, and the support is executed floating at anchor, the free end of the cable has a cargo, the blades have a curved shape and aerodynamic profile. Getting you can use during the freezing of the river.

The closest to the technical nature of the claimed invention is a unit for the energy of the fluid [2] containing a rotor with fixed blades mounted to rotate around their axes parallel to the axis of the rotor, generator, kinematically associated with the rotor. Moreover, the blades are made of hydrodynamic profile, the axis of rotation is placed at an offset is made in the form of sections of rectangular frames, and the rotor is mounted on vertical posts.

The aim of the invention is to simplify and improve the efficiency of the submersible unit all year round in any climate zone in a fluid environment.

The objective is achieved by the fact that in the proposed submersible unit for the removal energy of a fluid medium containing a rotor with fixed blades hydrodynamic profile set can be rotated parallel to the axis of the rotor and generator, according to the invention the rotor is fixed movably in parallel to the bottom and perpendicular to the flow on vertical racks, equipped with rectangular frames in the form of beams, rigidly fixed on the shaft of the rotor, forming together with blades on the shelves of Regaleali crossbars, and the generator connected to the rotor via a flexible shaft and a hydraulic drive. Sections of the rotor are offset relative to each other and each section contains at least three frames depending on the depth and velocity of the fluid.

In Fig. 1 shows a diagram of the location of the unit; Fig. 2 the layout of units in a fluid environment, top view; Fig. 3 scheme of work section in open fluid; Fig. 4 the same in a closed fluid.

The unit contains a rotor shaft 1 is rigidly planted on him by the hub 2 (Fig. 1), which strengthened girders 3. On the shelf bolt 3 is movable on hinges 4 set the blades 5. The rotor shaft 1 is movable by means of the bearing unit 6 and the slider 7 is mounted on the vertical posts 8 and is connected through a flexible shaft 9 and the hydraulic drive with the generator 10. The hydraulic drive consists of a hydraulic pump 11 of the pressure hose 12, the supply oil to hydromotor 13, which is connected by a coupling 14 to a generator 10. A hydraulic pump connected to the tank 15 through the oil suction hose 16. From the generator constant current is supplied to the power supply unit 17. Hours are transporting ears 18 and the float detection 19 and the flexible shaft 9 is enclosed in the cover 20. , otor the unit is lowered into the fluid perpendicular to the current, parallel to the bottom. Sessions depends on the velocity distribution and power flow (Fig. 3). To open the fluid velocity distribution from maximum to minimum changes from the surface to the bottom. (Fig. 3). For closed fluid such regularity is observed starting from the middle of the stream. The blades spin a shaft with a maximum difference in velocity in the stream. Under the action of the current environment, the blades 5 of the rotor located above the shaft of provisions I, II, III, overlap the area of the stream and creating the maximum resistance to flow, under the influence of the difference of the speeds begin to rotate the rotor shaft 1. The blades 5 are positioned below the axis of the shaft of the provisions of the IV, V, on the contrary, are deployed with the flow, freeing a path to flow through the space in the bottom of the girders, the maximum reducing resistance. The rotor rotates the shaft of the hydraulic pump II, the pump on the suction hose 16 sucks oil from the tank 15 and under pressure pushes it through the pressure hose 12 in the hydraulic motor 13. Of the motor 13, the oil goes back into the tank 15. The hydraulic motor 13 thus rotates and drives the generator 10. Speed units is regulated by the valve system.

The present invention can be used as microhydroelectric installed on rivers, canals and other Operating micro hydro does not violate the environmental conditions of the area, and the field solves some of the problems with power tools warning to protect against contamination of small water bodies, lighting settlements of oil and geologists, and other purposes. With respect to smaller rivers developed effective micro hydro for power supply of alarm alerts contamination of water bodies. Micro hydro is easily installed, without additional costs and water, earthworks, is a low cost, does not require special maintenance. You may find widespread use in small rivers. And as a hydraulic pump, hydraulic motor and electric generator can be used commercially manufactured equipment.
