The invention relates to a wave hydropower and can be used in the wave pumping units.Known wave pump installation (and. C. the USSR N 1366683, CL F 03 B 13/12, 1986), containing support with blocks and stops, three-dimensional wave pump with driving and working bellows cameras that share the cover and bottom, connected to the pump suction and discharge side, the rotary input and vygodnoe fixed on a support, inlet and outlet connected to the lower part of the drive chamber and the pressure line to the bottom in the zone of the working chamber, the lid is provided with a load, and the drive and the working chambers are interconnected by means of a pipeline with a suction valve.The disadvantages of the known devices:
the complexity of the structural design of the installation consisting of two bellows chambers, blocks, four pillars, underbody, bumpers, two goods, and so on , which reduces the reliability of its functioning;
The efficiency of limited working volume of bellows chambers, the pressure in the chambers is limited by the weight of the cargo and the device when not in use the dynamic pressure waves, hence of limited value the efficiency of the installation.Also known wave pump installation. C. the USSR N 1453077, CL F 03 B 13/12, 1987), containing submerged under the water level of support and attached thereto by means of a vertical hinge rod with a variable volume chamber having a check valve, and a rod provided with stops and has a hinge section, and the float is made with a specific density close to the density of water, installed between the stops can be moved relative to the rod, and the working chambers is menotomy section of the rod.The disadvantages of the known devices are:
inefficient movement of the lever, the plate and the bellows, because they are under water pressure and post it on these elements creates additional resistance to their movement results in reducing the efficiency of the known installation;
the float movement along the axis of the lever toward the stop under the influence of crowding on the float the crest, trough, which movement is idle from the standpoint of operation of the known device, i.e. not using the potential energy of incoming waves;
finding a known working setup in a flooded condition, which makes it difficult for maintenance and increases the time spent on ensuring its operation.The closest in technical essence to the proposed installation is the device to use the power of the surf, contains a lever mounted thereon a swinging vane and piston pump, the piston of which is kinematically connected with the lever, in which, to stabilize the load when changing power of the surf and increased reliability, the blade is equipped with a mechanism of regulation of its length, the implementation of which can move along the arm, the kinematic connection of the piston pump with lever made in the form of a crank, and the pump is located above the water level.The disadvantages of the known devices:

To swivel the ring elements 8 and 9 attached to the curved pipe 5 and the telescopic arms, made in the form of hollow rods 15 and 16 and mating with them ø what are the tabs 19 and 20. The supporting platform 21 is installed above the water level.Wave lift installation works as follows.Roll forward and rollback waves affect drive the blade 10 by turning it about the axis line 1, towards the shore and from him. The amplitude of the curved pipe 5 corresponds to the amplitude of oscillation of the blade 10. When roll the waves on the shore (see Fig. 2) drive the pendulum blade 10 with the curved pipe 5 is deflected synchronously in the same direction. The blade 10, moving in the direction of the shore, creates a back pressure wave in the area of the immersion end of the socket 6 of the pipe 5, contributing to greater filling with water it is immersed part. Under the influence of water pressure going into the cavity of the pipe 5 through the end bell 6, the valve 11 opens, and the valve 12 will be closed, which together with the open valve 13 and a closed valve 14 provides for the movement of water in the direction of the line 1 from the top of the duct 5.When you roll back the waves from the shore, it affects the drive of the blade 10 with the other hand. Top, relative to the previous position, the portion of the pipe 5 with an end socket 7 and the valve 14 is immersed in water ml 5 through the end bell 7, the valve 13 is closed and the supply of water in the main line 1 is provided in this case (when the closed valve 11 and open valve 12 from rising up part of the pipe 5 with an end bell 6.Subsequent roll forward and fall of the waves turns (fluctuations) of the blade 10 with the pipe 5 will be repeated periodically. The pipeline 5 and the blade 10 is balanced so that at rest, the blade 10 is located in a vertical plane.The economic efficiency of water wave setup is achieved through more cost-effective to perform their function - lifting water through direct use of wave action of the water on receiving the blade with the exception of intermediate technical parts and manufacturing operations.
