hydroelectric power plants, and through the latter with the sea and the turbine 15, respectively.Compensators are 3-sharnirnyy pipelines with two end and one intermediate hinges.Pipe expansion joints 12 are located at different acute angles at the vertices of which are located intermediate the hinges, so that they can be rotated around the hinges and by changing the angles, and simultaneously the distance between the leaf hinges, which are attached to the nozzle manifolds 36 and 37 of the movable piston pumps 9 or stationary collectors 13 and 14 wave hydroelectric power.The intake manifold 13 wave hydroelectric power plant is designed to supply water from the sea to the suction reservoir 36 piston pumps 9 using expansion joints 12 and represent the pipeline with the pipe to which are

initial position, the piston pumps 9, collectors 36 and 37 pumps, manifolds 13 and 14 hydroelectric power plants, compensators 12 and the turbine 15 is filled with water.Consider Ravnopravie lever 3 with floats 5 at the ends and connected piston pumps 9 on the excitement with the design for this lever wavelength at which the left float is at the top of the crest of a wave right in the middle of the depression, and the stroke of the pistons of the pumps maximum.While the side bars of the lever 3 is partially extended from the tubular Central portion by an amount equal to half of the stroke of each piston of the power cylinder 6 and the axle housings piston pump 9 in the longitudinal grooves of the frames 8 are in the middle position.During the passage of the wave in the direction from right to left equal armed lever 4 starts to rotate around the axis 2 hours against the spine with radius equal to the distance between the centers of the axes and float to a height equal to the height of the calculated wave, and the right float 5 at this time rises from the valley to the crest of the rolling waves along the same path.Both float make small reciprocating movement in a horizontal direction.Located in the extreme upper position of the piston 19 with the rod 20 of the piston pump 9 connected to the left float 5, starts to fall, and the pump on the pins is moved along the grooves of the frame 8 from the middle position to the left (at the moment of passing the float level of the calm sea) and back, making a reciprocating motion. Upon increase of pressure in the lower part of the cylinder 17 is compressed spring 35 of the injection valve 33, the valve is opened and water under pressure through the housing 23 of the valve chest, the pipe 29, the pressure reservoir 37, the compensator 12 and the discharge manifold 14 enters the turbine 15, causing rotation of the turbine and associated electric generator 16.At the same time in the upper part of the cylinder under the action of discharging compressed spring 34 of the suction valve 30, the valve opens and water from the sea through the suck is in the cylinder 17.When lowering the left of the float 5 the slope of the wave from crest to a trough acute angles between the movable pipes in the peaks of the joints 12 first increase and then decrease to the original value, compensating for periodic changes in the distances between the reservoir 36 and 37 of the piston pump 9, pivotally connected with the left float and fixed collectors 13 and 14 wave hydroelectric power.During the passage of the wave in the direction from right to left equal armed lever 3 starts to rotate around the axis 2 counterclockwise due to the fact that the right-float 5 rises on the slope of the wave trough to the crest along the arc of a circle with radius equal to the distance between the centers of the axes and float to a height equal to the height of the calculated wave, and the left float 5 at this time descends from the crest into the hollow rolling waves along the same path.Both float make small reciprocating movement in a horizontal direction.Located at the lowest position of the piston 19 with the rod 21 of the piston pump 9 connected with the right float 5, begins to rise, and the pump on the pins is moved along the grooves RA is making a reciprocating motion.Upon increase of pressure in the upper part of the cylinder 17 is compressed spring 35 of the injection valve 32, the valve is opened and water under pressure through the housing 22 and valve boxes, conduit 28, discharge manifold campensation 12 and discharge manifold 14 enters the turbine 15, causing rotation of the turbine and associated hydro generator 16.At the same time in the lower part of the cylinder under the action of discharging compressed spring 34 of the suction valve 31, the valve opens and water from the sea through the intake manifold 13, the compensator 12, the intake manifold 36, the pipe 27 and the housing 23 of the valve chest enters the cylinder 17.When lifting the right of the float 5 the slope of the wave from trough to crest the sharp corners between the movable pipes in the peaks of the joints 12 first increase and then decrease to the original value, compensating for periodic changes in the distances between the reservoir 36 and 37 of the piston pump 9, pivotally connected with the right float and fixed collectors 13 and 14 wave hydroelectric power.Next, the above cycle is repeated continuously.With increasing wavelength above calculation for Ravena and rod of the power cylinder 6, the amplitude of oscillations of the lever is reduced and Vice versa.In both cases, the load wave hydroelectric power is stabilized.Works similarly equal armed lever 4 with floats 5 at the ends and connected with them piston pump 9 on the excitement with the design for this lever wavelength at which the left float is at the top of the crest of a wave right in the middle of the depression, and the stroke of the pistons of the pumps maximum.The levers 3 and 4 swing around the axis 2 simultaneously and independently from each other with a frequency of excitement.Depending on the ratio of the lengths of the equal armed levers like the floats 5 (left or right) can operate in the same phase (waves) or in opposite phases (one on the crest, and the second in the cavity).All piston pumps 9 are connected in parallel and operate on manifolds 13 and 14 wave hydroelectric power.The location of the at least two floats at the ends of the equal armed lever, swinging around a horizontal axis, allows to simplify the design and increase reliability.The execution arm of variable length by means of a power cylinder stabilizes the load wave hydroelectric power p is s gives the possibility of extending the lengths of the waves used. 1.
