The invention relates to the field of hydraulics and can be used for lifting water in coastal zones of the oceans, seas, large lakes and reservoirs.

Known hydraulic RAM containing nutrients pipe, an air cap to the discharge pipe and check valve that tells the air cap with the feed pipe, the float valve, one end of nutrients pipes are placed in the pond, with the possibility of periodic filling with water the waves of the sea, the other end of the tube is closed and the float valve is located near the closed end of nutrients pipe. The end of nutrients pipe placed in the pond, has the shape of a truncated cone, the larger base of which is directed to the reservoir (RU # 2218484, IPC F04F 7/02, publ. 10.12.2003,).

Among the disadvantages of this design it should be noted that a significant part of the kinetic energy of the incoming waves is converted into pressure energy to be used at your own reflection from the inner surface of the cone, i.e., its movement towards the water surface.

Known hydraulic RAM including shock and discharge valves, air cap, the feeding tube with water-receiving part, injection pipe and the receiving tank, Taran provided with outlet pipe with a valve-clapper from the water surface and the funnel, the message is authorized through the shock valve feed pipe, on the other hand, when the receiving portion of the supply tube is made of a compound that includes a ring, the nozzle and the confuser, and the ring is made rotatable about a vertical axis, and the input section of the nozzle is installed in place of the maximum speed of the tidal wave (RU # 2367826, IPC F04F 7/02, publ. 20.09.2009,).

Among the disadvantages of this design it should be noted that the dissolution of air in the air cap when working hydraulic RAM, and the absence of a mechanism for automatic adjustment of the closing shock valve for each subsequent incident wave with its individual parameters of the kinetic energy.

The closest technical solution of the essential features is a hydraulic RAM that contains a nutrient tube with shock valve, an air cap to the discharge pipe and valve that tells the air cap with the feed pipe, which is connected with the tank, shock valve is provided with a socket, the lower end of which is made in the form of a bellows with a rod connected with the shock valve, and a pipe connected with the tank and installed above the level of the bellows (SU # 1173077 And IPC F04 7/02, publ. 15.08.1985 year).

A disadvantage of the known technical solution is the need for periodic pumping air into vozdushnyy, what complicates the operation of the device, furthermore, the connection pipe with the tank above the level of the bellows makes it difficult working hydraulic RAM when the water level in the tank is lower than the level of the bellows.

An object of the invention is to improve the efficiency of hydraulic RAM from the implementation of the automatic adjustment of the shock valve for the individual parameters of each incoming waves and eliminate the need for pumping air into the discharge hood.

The technical result is achieved due to the fact that in the design of tidal hydraulic RAM containing nutrients pipe, one end of which is placed at the water's edge, with the possibility of periodic filling of the incident wave, and at the other end of the installed shock valve, an air cap to the discharge pipe and the discharge valve, indicating an air cap with feed pipe, shock valve, provided with T-shaped pipe, the upper end of which is made vertically and communicated with the atmosphere, the lower end is made in the form of a bellows with a rod connected with the shock valve, additionally introduced the hollow damper and valve, and on one side of the hollow damper is a plot of the hydraulic network connecting the discharge valve and discharge the pipeline, the other side of the damper facing into the internal cavity of the air cap, which, through the check valve communicated with the atmosphere, and the third end of the T-shaped pipe of the shock valve hydraulically connected to feed pipe and put in the center section nutritious pipe facing to the lake, and herself a feeding tube is in the form of a cone, the base of which is directed to the reservoir, and the top is the installation location of the shock valve.

The proposed design undertow hydraulic RAM shown in the drawing. Undertow hydraulic RAM includes nutritional pipe 1, the shock valve 2, an air cap 3, the discharge pipe 4, the discharge valve 5, the T-shaped pipe 6, the bellows 7 and rod 8, the hollow damper 9 and the check valve 10.

Undertow hydraulic RAM operates as follows. Initially the air cap 3 through the check valve 10 is pumped air or another gas (e.g. nitrogen or helium) to pressure values determined by the design parameters tidal hydraulic RAM and the required height of water injection. Then a feeding tube 1 is firmly fixed on the stretch of coast in the area of flooding tidal waves (not shown) the base of the cone toward the oncoming waves. After that, the energy quantity d is to achieve an incident wave will provide the flow of water in the nutrient tube 1 and the T-shaped pipe 6. Water will begin to flow from the feed pipe 1 through the open drum valve 2, trying to inspire him and close, and the height of the water column in the vertical end of the T-shaped pipe 6 will provide a given resistance to the closing of the shock valve 2 via the shaft 8 of the bellows 7. In closing drums valve 2 will occur the phenomenon of water hammer, a positive wave propagation which will provide the supply portion of water from the feed pipe 1 through the discharge valve 5 in the hollow damper 9, clutching at the air contained in the air cap 3. When the pulse energy of momentum of the wave runs out, the pressure from nutrient pipe 1 and the hollow damper 9 will be counterbalanced, the discharge valve 5 closes. Under the action of waves water hammer and weight of the liquid column in the T-shaped pipe 6 opens automatically shock valve 2, and the accumulated portion of water in the hollow damper 9, under the action of excessive air pressure in the air cap 3, will have a tendency to move in the discharge line 4. With each subsequent incident wave process undertow hydraulic RAM will be repeated in the above-described sequence will be automatic adjustment of the weight of the shock valve 2, the corresponding fill rate is nutritional is th pipe 1 water rolling waves. The end of the T-shaped pipe 6 connected to the feed pipe 1, it is recommended to place in the center of its cross section, because this place is the velocity of flow in a nutrient trumpet 1 highest and adjusting the weight of the shock valve 2 will be implemented with less delay. This automation settings work undertow hydraulic RAM helps to improve its effectiveness.

Execution nutritional pipe 1 in the form of a cone, the base of which is turned towards the oncoming waves, will provide a more dense stream filling her section in the setup of the shock valve 2, which is the apex of the cone, which will enhance the efficiency undertow hydraulic RAM.

The use of a hollow damper 9 in the air cap 3 eliminates the possibility of dissolving air under pressure in the water, and hence the need for its periodic paging in the air cap 3 that, in General, increases the reliability of the device.

The result of this construct, tidal hydraulic RAM provides a relatively high reliability of the device by eliminating the need for pumping air into an air cap and improved efficiency from the implementation of a mechanism to automatically adjust the weight of the shock valve is od individual parameters of each incoming waves.
