The invention relates to the field of energy with non-traditional way of receiving and converting the energy received from the use of gravitational forces perturbations of the water surface.Known design breaking the Cockerell raft , which combined three pontoon hinges, profiling the surface of the waves.The disadvantages of this device include greater inertia of the system, and therefore it is less effective.It is known device  to convert wave energy into electrical pulse containing two pontoons rigidly interconnected by a link, in the middle of which the axis of sakrana moored congresa, thereby reducing the amplitude of swinging of the pontoons.The purpose of this invention is to eliminate these disadvantages can only be achieved by the fact that the oscillation of the water surface is captured using two cylindrical pontoons interconnected at a distance of half the length of the optimal wave, hollow partitioned plate, the cavities of which is liquid filled to half its volume.Movement of fluid from one side of the cavity to another allows you to move the center of gravity of the device, making it necessary to oscillate the device with greater amplitude relative to the fixed keel, sunk to a depth not less than 1/2 of the maximum wavelength for a given area, where is the outrage on the surface below this depth is not affected and can cover a very wide range of wavelengths, i.e., to work more efficiently, with greater efficiency.The drawing shows a profile view of the device.The energy Converter is a floating tool composed of two pontoons 1 and 2, each having three buoyancy, rigidly connected partitioned by the plate 3, in the longitudinal cavities 4 which is enclosed by incosolable 6 in the form of spherical cameras, where the pipe 7 with the suction valve 8 and the exhaust pipe 9 to the discharge valve 10. In the middle of the plate 3 on the hinges 11 are attached to the rod 12, the retaining fin 13 of the two rigid plates arranged between the vertically at a distance of 1/3 the maximum length of a wave, and the bottom plate buried at 2/3 the size of the waves, and the area of each plate equivalenta the middle of the pontoon. To the plate 3 and the rod 12 pivotally mounted piston pumps 14.The power Converter operates as follows.At clash of the waves on the pontoon 1, which, by virtue of its reserve buoyancy, floats on the waves and picks up the edge of the plate 3, the liquid 5 to the cavity 4 rushes to the side of the pontoon 2 into the chamber of the air cap 6, clutching in the air.Moving fluid 5 produces the displacement of the center of gravity of the device to the side of the pontoon 2, which is due to this even more immersed, and the pontoon 1, on the contrary, a few POPs up, causing the plate 3 takes place at a large angle and the liquid 5, due to the existing inertia device, keep pace with the speed of the wave by accelerating their movement. The oscillation plate 3 relative to the rod 12 moves n is dcost 5 under the pressure of the compressed air rushes through the cavity 4 in the direction of the descending end of the plate 3 into the chamber of the other of the air cap 6, shifting the center of gravity to the left, plunging the pontoon 1 and simultaneously forcing to float the pontoon 2.Moving fluid 5 from one side to the other in the cavity 4 is performed with increasing speed, and protection from surges of fluid occurs due to the work on kompremirovannyj air chambers air boxes, where the role of the piston performs the liquid 5. When reaching the air pressure set values opens the exhaust valve 10 and discharged portion of the compressed air in pneumatic team network through pipe 9. On the reverse movement of the liquid 5, when in the chamber of the air cap 6 occurs, the vacuum opens the suction valve 8.This device allows for great excitement to accumulate energy in two ways, which makes the device more versatile and effective. Energy Converter comprising a plate rigidly connecting the two pontoons, the rod holding the keel, and piston pumps, characterized in that the connecting plate has a longitudinal cavity, filled to half its volume of fluid and a weight equal to 1/4 the displacement of one of the pontoon, the ends of which are vertical air caps in videosteen, installed respectively at a depth of 1/3 and 2/3 of the maximum wavelength of the study area, with each plate area equivalent to the midsection of the pontoon.
