The invention relates to hydropower and, in particular, to devices water supply from rivers.Known feeder water, typically performed on the basis of the electric motor, which causes the rotation of the various hydraulic pumps: centrifugal, reciprocating, gear, diaphragm and other  . The main disadvantages of such devices is the inevitable need for outside energy sources: electric batteries, mechanical actuators based on thermal engines or mobile power station is. The disadvantage of such devices is the inability to obtain high values of efficiency, power and specific indices: weight/power ratio, and low, for devices with perpendicular to the flow axis of rotation, the values of the energy utilization factor ).Object of the invention is the creation of an Autonomous mechanical device that would use energy from the environment to perform mechanical work for water supply.To solve this problem is proposed a device that uses only the energy of the moving river water. It can be used in any location where there is a river, canal or similar artificial structure.In the proposed device used well-known phenomenon of self-oscillations of a plate in the fluid flow , called flutter. Using the proposed device is the conversion of vibrational energy into mechanical energy to move the liquid.The essence of the invention is a submersible pumping unit supplying water from the river or canal through the use of energy water stream containing a support and installed with the possibility regards the but hanging on the rack frame, consisting of two beams with a barbell, and rocking, and the plate on the rear edge secured to rotate on an axis between the beams, and its front edge is connected with the damper and stop with frame. Submersible pumping unit is installed on the bottom of the river and balanced load. The pump through intake valves takes water from the surrounding space and delivers it under pressure through the main pipeline to the consumer. The consumer (capacity, power, etc.,) may be located on shore or elsewhere.The list of drawings.Fig. 1 - General view of the submersible pumping unit.Fig. 2 - scheme of installation of submersible pumping unit.Fig. 3 is a schematic diagram of a submersible pumping unit.Fig. 4 - device and circuit operation of the valve of the pump.The device consists of a support 1 (Fig. 1) and installed with the possibility of rotation of the plate 13 connected to the pump 4. The pump 4 is made two-way. Bearing 1 is equipped with a rack 7, and the connection plate 13 with the pump 4 is made in the form of a pivotally suspended on the rack 7 of the frame 12 consisting of two beams from the rod 9, and rocking 8, and the plate 13 to the rear edge of the fixed 12. The stop 10 is arranged to change the position relative to the frame. The angle and speed of rotation of the plate 13 are limited to special hydraulic damper 11. The rod 9 is arranged to adjust the line size to change the area of the plate 13. The frame ends 12 self-cleaning hinges, by which it is hung on the rack 7. At the top of the rack by means of the bracket 5 is mounted two-way hydraulic pump 4. Mentioned rocking 8 is connected to the frame 12, allowing the transmission of motion from the frame 12 on the piston rod of the pump 4. Hour 7 is adjusted by means of the slot 2 on the support 1. The rigidity of the connection of the rack 7 with the support 1 is provided by the statement of marks 3.The principle of the proposed device consists in the following. Submersible pumping unit is installed on the bottom of the river or canal with flowing water (Fig.2). When the flow stream of the liquid on the plate occurs hydrodynamic force F (Fig.3), which is the projection of Fuon the axis perpendicular to the axis of the frame. Force Fucreates a moment about the pivot point of the frame Acting on the opposite end of the frame is valid, the resistance force from the piston pump fn. Under the action of SOA depends on the generalized axial moment of inertia of all rotating elements J and the current torque M
< / BR>Rotation of the frame causes the change in the angle of the leakage flow (decrease) on the plate. As soon as he becomes another sign, the force acting on the plate, also changes its sign. This leads to a moment of force which makes the plate rotates about a point a (Fig.3) to shift to the opposite extreme angular position defined by adjusting the position of the damper. The speed of the transfer plate is determined by the characteristics of the damper. After putting the plate frame is decelerated to a complete stop, and then starts a rotational movement in the opposite direction. Thus, under the action of alternating hydrodynamic forces arising on the plate, the frame performs an oscillatory motion. It is converted by the rocking 8-in reciprocating movement of the rod with the piston in the pump 4. When the piston one cavity (the opposite direction) is filled with liquid, and the other cavity at this time, the liquid displaced by the piston. To implement such a cycle in the pump uses special valves, which are made in the form of freely rotating end cap, closed in the absence of differential pressure. The design of such a valve is shown in Fig.4. ing the closing of the valve even when the equality of the pressures P and P0(Fig.4). When P>P0(A) is the opening of the valve, while PP0the valve is closed (B). At the same time cleans the contact surfaces from mechanical particles are washed out, because the valve does not close instantly. River water is a chemically aggressive environment with a variety of mechanical impurities in the form of sand, silt, etc., To extend the service life of the hinge joints in locations with high load hinges of the frame 12 (Fig. 1) and the rack 7 are self-cleaning in the form of a cage and sleeve with grooves on them, arranged at an angle to the axis of rotation and towards each other. During rotation of the sleeve relative to the stationary casing grains of sand and other solids, rolling, discharged into the grooves, where washed with water. At the same time the water from the grooves ensures wetting of the rubbing surfaces, which reduces friction and wear.Changing the position of the stop 10 with respect to the beams of the frame 12 allows you to set the value of the limit angle of deflection plates 13.Thus, the proposed device allows to achieve the desired result using the energy of the flow of fluid to perform useful mechanical work and the supply of water to the consumer is 66.2.
