The invention relates to irrigation systems. Water the site is designed to work in open watercourses in the presence of an energy source in the form of a hydraulic differential on the retaining structure.

Known invention (WO 3016710 A1, 13.07.02, PCT/DK02/00496, Hydropower plant, journal of world Inventions, issue 66, No. 2/2004), equipped with a turbine shaft and a belt transmission that uses the energy of falling water is relatively small flows.

Also known invention (RU patent for invention, 2117093 C1, 6 EV 13/02, 1998 - the authors used as a prototype)that contains a camera with elastic capacity and two shoulders lever, a piston pump and a device that regulates the access of water into the elastic capacity of the magnetic switch. Power element of the device is elastic capacity, which is in communication with the upper water filled, puts pressure on the space-lever and actuates the piston of the pump.

The disadvantages of this device are: the bandwidth limitation of the discharge; low productivity of water lift due to the small diameters of the inlet and outlet pipes; the need for periodic replacement of the elastic capacity while its wear; a substantial number of small structural elements, which reduces the reliability of the structure.

The technical solution for the ACI is creating pressure to lift the fluid while maintaining a significant bandwidth of the structure.

The task is achieved by the fact that in water the node that contains the camera with the access controller of water in it, the pipe culvert, the water lift in the form of pump according to the invention the camera has an aperture in which is located the valve control access of water into it, having a float, a stem and guide, while the camera is connected to a pipe outlet, which is a turbine shaft extending into the cavity of the chamber and communicated with the pump shaft water lift.

The novelty of the invention lies in the fact that as a result of use in the design of lifting node of a new set of features, namely a closed chamber with an opening blocked by a regulator valve water access, connected with pipe outlet, which is the power element of the turbine, the shaft of which extends into the cavity of the camera and rotates the pump shaft, an optimum throughput facilities, maintain the desired hydraulic differential levels on the retaining structure, creates pressure and is lifting.

According to the patent and scientific literature is not found similar technical proposal that allows to judge about the level of invention proposals.

The invention is illustrated by drawings, where figure 1 shows the design of lifting node RA is cut; figure 2 - the same plan.

Water lifting unit consists of a closed concrete chamber 1, in the upper panel of which has an opening 2 closed by the valve 3 control access of water into the chamber 1. The valve 3 is rigidly connected by a rod 4 float 5 and can be moved along the guide 6, located inside shaft 4. The guide 6 is fixed the lower end in the bottom panel of the concrete chamber 1 and passes through the center of the hole 2. Camera 1 is connected to pipe water outlet 7 located at the base of the supporting structure 8. In-pipe water outlet 7 installed turbine 9 role of the power element, the shaft 10 of the rotor which extends into the cavity of the camera 1. Through a belt drive 11 of the shaft 10 rotates the shaft 12 of the pump 13 having a suction inlet 14 and outlet pipe 15. Belt 11 passes through the top panel of the camera 1 through the opening 16. The access of water into the chamber 1 through the opening 16 is limited by a casing 17 mounted on the top of the camera 1.

Flash site works as follows. Camera 1 at the lower position of the valve 3 is closed and water accumulates upstream of the retaining structures 8. With the increase of water level of the upstream (UVB) increases the buoyancy force on the float 5, associated with the valve 3 valve 4. When the preset level of the upstream (UVB), sufficient to create RA is Otsego hydraulic differential (Z) and downstream (UNB), the buoyancy force on the float 5 exceeds the pressure holding valve 3 and the valve 3 floats with float 5, opening the access of water into the chamber 1. Water through the chamber 1 and the pipe outlet 7 rushes into the lower reach. The flow of water rotates the turbine 9. The shaft 10 of the turbine 9 through a belt drive 11 includes a pump 13. The pump takes the water through the suction pipe 14, creates pressure and pressure through the pipe 15 delivers water to consumers. When the detected level of the upstream (UVB) reduced hydraulic gradient (Z) and the efficiency of the turbine 9. When the level of the upstream minimum marks to ensure effective operation of the turbine 9, the valve 3 closes the opening 2, the flow of water through the chamber 1 is stopped, the turbine 9 and the water lift stops and starts the accumulation of water upstream. Upon reaching the level of the upstream (UVB) maximum level, the float 5 opens the valve 3 and starts the next cycle of operation of the hydropower site. The control range of the levels and the magnitude of the hydraulic gradient on the structure are governed by the selection of the diameters of the valve 3, the volume of the float 5 and the length of the rod 4.

Water the node that contains the camera with the access controller of water in it, the pipe culvert, the water lift in the form of a pump, otlichuy is the, the camera has an aperture in which is located the valve control access of water into it, having a float, a stem and guide, while the camera is connected to a pipe outlet, which is a turbine shaft extending into the cavity of the chamber and communicated with the pump shaft water lift.
