Known water-lifting device is a hydraulic RAM (Hovsepyan V.M. Hydraulic RAM and RAM setup. - M.: Mashinostroenie, 1968, 124 S.), contains a source of water supply line, an air cap, pressure pipe, pressure tank and using the system water-air to support the process of water lift.

Also known invention (RU, patent, 2318956, C1, E02B 13/02, 2006 - prototype)containing a chamber with inlet and outlet nozzles, float rod and guides the water lift in the form of a pump.

The disadvantage of the first device is the fact that most of the flow is transient, i.e. only a small portion of the water passing through the fuel nozzle, served in the discharge nozzle. Also for the efficient operation of this device requires large values of flow and pressure.

Disadvantages of the second device are a significant number of hydro-mechanical devices that reduce the reliability of the structure as well as the need for major reconstruction, for use on the working structures.

The technical result is to decrease the amount of transit flow (blank water) and hydro-mechanical devices.

The technical result is achieved by the fact that water site, with the holding chamber with inlet and outlet nozzles, the float rod and the guides and the pump is a water lifting machine according to the invention, the camera is provided with an air valve and a duct with a check valve to supply compressed air to the pump-water lift and float rod and the guide is located in the chamber, and float through stem communicated installed at the outlet port of the valve shutter and has a cover made of a ferromagnetic metal on the top of which is a rubber seal on the input socket is also a rubber seal, which together with the seal, located on the lid, with the ascent of the float to provide a hermetic sealing of the inlet pipe having a constant magnets, locking the float in its upper position after surfacing.

The novelty of the claimed proposal is that in the design of lifting node a new set of structural characteristics, namely the camera with an air valve and a duct with a check valve, float and rod, and guides located inside the chamber and the permanent magnets, is provided by the production and accumulation of the energy of compressed air to lift the fluid with the use of air-hydraulic pressure system and its use for pump-water lift (this reduces yostoi water discharge and decreases the number of hydro-mechanical devices).

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 is presented the construction of a water site (the closed position of the outlet pipe and open the inlet nozzle, in a state of filling the chamber with water and the beginning of the displacement of the accumulated air and feeding it to the pump); figure 2 shows a position close to the maximum filling of the chamber with water; figure 3 shows the maximum full of Luggage, the ascent of the float closes the inlet nozzle and the opening of the outlet pipe, start draining the water and filling the air chamber; figure 4 - shows the position of the system when draining water to the minimum water level in the chamber and maximum filling the chamber with air, with the subsequent opening of the inlet pipe and closing of the outlet pipe.

Water the site consists of a chamber 1, which is a sealed tank, with an inlet 2 and outlet 3 nozzles. Inlet pipe 2 is connected nutritious tube 4, which inlet is equipped with a diffuser 5. Camera 1 provided with an air valve 6 to fill it with air and a duct 7 which is supplied compressed air to pump water lift 8 running through energy sialogogue. The duct 7 at the inlet is equipped with a check valve 9. Camera 1 is equipped with a float 10, which is connected by a rod 11 with the valve gate 12 installed on the outlet port 3. The top cover 13 of the float 10 is made of a ferromagnetic metal. On top of the lid 13 is a rubber seal 14, and the inlet pipe 2 is rubber seal 15, which together with the rubber seal 14 in the ascent of the float 10, walking along the guides 16 arranged in the chamber 1, provides a hermetic sealing of the inlet pipe 2, which established the permanent magnets 17, locking the float 10 in the upper position after surfacing. The float 10, with the valve gate 12, the guides 16 and the permanent magnets 17 together constitute the access controller and reset the water in the chamber 1. Also in the construction of the hydropower site is provided by the audit chamber compensator 18 and 19 to reduce water hammer when closing input pipe 2.

Flash site works as follows. When the open position of the inlet pipe 2, the outlet 3 is closed by the valve gate 12, starts filling the chamber 1 water from the upper reach (figure 1). Filling occurs due to the presence of hydraulic difference Z between the upper and lower downstream. Hydraulic differential level is th is created on the tubular moving irrigation systems in place mates drainage-discharge channels of different orders of magnitude, when the channel of the Junior order in the retaining mode. When filling the chamber 1 with water, there occurs the pressure of the air and is replaced and the air flow through the duct 7 to the pump-water lift 8. Filling the chamber 1 water occurs to a certain level HCmax(figure 2), in which the hydrostatic lifting force (Archimedes force) becomes greater than the force of the hydrostatic pressure acting on the valve-gate 12, and pushes the hollow cylindrical float 10. The rise of the float 10 (figure 3) along the guide rails 16 to the top of the rubber seal 15 input socket 2. Reaching the rubber seal 15 input socket 2, the cover 13 of the float 10 is attracted and fixed permanent magnets 17, which leads to tight the closure of the inlet pipe 2, a rubber seal 14 and the rubber seal 15 input socket 2. Water hammer when closing input pipe 2 is softened by raising the water level in the compensator 19. When changing the position of the float 10 is closing input pipe 2 and the opening of the outlet pipe 3 and phase begins draining the water from the chamber 1 with the closure of the check valve 9 and opening of the air valve 6 (slight vacuum)through which air arrives and takes all given to him about the eating. Emptying the camera 1 is to the level HCmin(figure 4), in which the hydrostatic lifting force and holding force of permanent magnets 17 is less than the weight of the float 10 and the pressure force of the water on the cover 13 from the inlet pipe 2, which leads to the change of position of the float 10. The float 10 is lowered, the valve gate 12 closes the outlet 3, opens the inlet 2. Starts filling the chamber 1 with water (figure 1) and the air supply to the pump is a water lifting machine 8, the next cycle begins. When this pump is a water lifting machine 8 delivers the water from the discharge channels of the network in the irrigation channels for re-use for irrigation or other forms of economic use.

Flash site containing a chamber with inlet and outlet nozzles, the float rod and the guides and the pump is a water lifting machine, characterized in that the camera is provided with an air valve and a duct with a check valve to supply compressed air to the sediment-water lift and float rod and the guide is located in the chamber, and float through stem communicated installed at the outlet port of the valve shutter and has a cover made of a ferromagnetic metal, the top of which is a rubber seal on the input socket is also rubber seal, to the which, together with the seal, located on the lid, with the ascent of the float to provide a hermetic sealing of the inlet pipe having permanent magnets, locking the float in its upper position after surfacing.
