The invention relates to gidroenergetike, and more particularly to a hydroelectric power plants, using the power of the surf and reflected waves that occur on the existing coastal hydraulic structures, such as the x reservoirs of natural and artificial origin.

Known for breaking hidroelektrane installed on the breakwater contains a working body with piston pumps, turbine and associated electric generator.

The working body is a series of installed along the breakwater spherical floats are pivotally attached to brackets fixed to floating on the breakwater frame.

Between the floats and the frame below the water level set piston pumps, made in the form of cylinders with spring-loaded pistons.

Floats actuate spring-loaded pistons moving in the cylinders are equipped with holes to fill them with water and telescopic pipes with header for supplying water under pressure to the turbine.

The latter, together with the generator installed on the crest of the breakwater, and the frame on his wall facing the open sea.

In the initial position cylinders filled with water, and the pistons and their associated hinge using levers floats are in the leftmost position.

Under the action of incident breaking waves floats closer to the wall of the breakwater and, compressing piston water pump cylinders on telescopic the awn design, due to the presence of the levers with the hinges, the moving frame with brackets and telescopic discharge pipe.

Do not use the energy of the standing wave due to the addition of the rolling surf and reflected waves.

These drawbacks are partially eliminated in the known device, installed on the breakwater.

The device contains voenoplennih working body with piston pumps, piping and check valves and the turbine to a generator.

Voenoplennih work the body in the form of still installed in the pond at some distance in front of the breakwater vertical frame guides and installed inside the frame can move asymmetric float, which simultaneously swinging around a horizontal axis.

The latter is moved vertically by rollers squeezed between the rails and connects the float with its companion piston pump double action.

The float plate has a protrusion located on one side of the axis and intended for the perception of the rolling waves.

On the opposite side of the float lever is provided ledge, using the effects.

The device is equipped with a special work area for maintenance equipment and transitional bridge to connect with breakwater.

The float has a few cameras that you can fill with water to change the buoyancy of the float when changing power of excitement.

At clash of the waves on the plastic tab on the float experiencing vertical motion, the energy of which is converted to the pressure of the hydraulic fluid in the first doubles piston pump double action.

At the same time the energy swing float around the axis is converted to the pressure of the hydraulic fluid in the second doubles piston pump.

Then the hydraulic fluid from the pump through the piping and check valves is routed to a turbine, which spins a generator.

Low efficiency, since the asymmetrical float with unilateral plate protrusion is not possible to use the energy of the reflected wave.

The need for securing the vertical frame with float in the sea floor, the presence of a working platform and bridge complicates the design tidal hydroelectric power.

The range of lengths used standing waves is limited and can the e efficiency, to simplify the design tidal hydroelectric power plant and the expansion of the range of lengths used standing waves.

This technical result is achieved by the fact that known tidal hydroelectric installed on coastal hydraulic structure containing water turbine with generator and set in front of the hydraulic structure from the side of the reservoir voenoplennih working body with piston pumps, piping and check valves connected to the turbine, while voenoplennih work the body in the form of a float that is installed inside the vertical frame can be moved and piston pumps connected in parallel to the manifold through a check valve supply at least one additional float is installed inside the vertical frame can move, and the frame is installed on a hydraulic structure can move in the horizontal plane.

The valves 9,10 installed in horizontal pipelines connecting the joints 8 with the reservoir 11 so that water flows only in the direction of the reciprocating pump 5 through a manifold into the turbine and is designed for continuous water flow in the turbine 12, regardless of what floats and associated pumps are currently under the influence of the standing wave.

The collector 1 is used to collect water under pressure coming from piston pumps 5 and supply it to the turbine 12. The collector laid on the breakwater and is connected to the pump using gorizontalnom 13, designed for power.

Hydroelectric works in the following way. In the initial position, the piston pumps 5, the reservoir 32, 33 of the pumps, expansion joints 8, horizontal pipes with check valves 9, 10, the collector 11 of the hydro and turbine 12 is filled with water.

Frame 4 is immersed in water to a depth slightly greater than the depth of floats 2, 3, located in the cavity standing wave.

While the cylinders 7 half extended, and United with them frame the same distance does not reach the wall of the breakwater 1.

Consider the operation of the float 2 inside the frame 4 and the associated piston pump 5 to the excitement.

In the process of formation of the rolling surf and reflected from the breakwater waves in the area of location of the float 2 is a standing wave and the mass of water begins to rise at a rate that decreases with distance from the wall of the breakwater.

Meeting on its way limited by the perimeter frame 4 float 2 standing wave creates a buoyancy force, under the action of which the float rises vertically upwards and through the rod 17 moves the piston 16 upward until it stops tolmino the ina 31 injection valve 28, the valve is opened and water under pressure through the housing 18 of the valve chest, the pipe 24, the pressure manifold 33, the compensator 8, a horizontal line, the check valve 9, the collector 11 is supplied to the turbine 12, causing rotation of its associated generator 13.

Is the first stroke.

At this time, the check valve 10 is closed, as the water pressure before the valve side of the piston pump will be lower than in the reservoir 11.

At the same time in the lower part of the cylinder under the pressure of discharging compressed spring 30 of the suction valve 27, the valve opens and water from the sea through the vertical pipe, the intake manifold 32, the pipe 23 and the body 19 of the valve chest is fed into the cylinder 14.

Then due to forces of adhesion of liquid bounded by the perimeter frame 4 float 2 starts to fall vertically down into the hollow arisen standing wave and using the rod 17 moves the piston 16 down until it stops thickened portion of the shaft 17 in the cover 15 of the cylinder.

With increasing pressure in the lower part of the cylinder 14 is compressed spring 31 and the discharge valve 29, the valve is opened and water under pressure through the housing 19 of the valve chest, Truboprovod the turbine 12, causing rotation of its associated generator 13.

There is a second working stroke.

On measures displacement of the standing wave along the breakwater 1 from the location of the float 2 in the area of the float 3 rises up the mass of water, meeting on his way limited by the perimeter of the frame 4, the float 3 creates a buoyancy force, under the action of which the float rises vertically upwards and through the rod 17 moves the piston 16 upward until it stops thickened portion of the stem in the bottom of the cylinder.

This buoyancy force of the float 3, changes in the water pressure in the cylinder 14 associated piston pump exceeds 5 at some point buoyancy force acting on the float 2 and the pressure of the latter in his pump, which determines Under the action of pressure drop water from the cylinder 14 is a piston pump, associated with the float 3, compressing the spring 31 and opening the discharge valve 28 is held in the housing 18 of the valve chest, the pipe 24, the discharge manifold 33, the compensator 8, a horizontal line, opens the check valve 10 and through the manifold 11 is supplied to the turbine 12, causing the rotation of the electric generator 13.

Is the first stroke.

At this time, the check valve 9 is closed, as the water pressure before the valve side of the piston pump 5 will be lower than in the reservoir 11.

At the same time in the lower part of the cylinder under the action of discharging compressed spring 30 of the suction valve 27, the valve opens and water from the sea through the vertical pipe, the intake manifold 32, the pipe 23 and the body 19 of the valve chest is fed into the cylinder 14.

Then due to forces of adhesion of liquid bounded by the perimeter of the frame 4, the float 3 starts to fall vertically down into the hollow arisen standing wave and using the rod 17 moves the piston 16 down until it stops thickened portion of the stem into the cap 15 of the cylinder.

With increasing pressure in the lower part of the cylinder 14 is compressed spring 31 and the discharge valve 29, the valve is opened and water under pressure to the rotation of the associated generator 13.

There is a second working stroke.

At this time, the check valve 9 is also closed, as the water pressure before the valve side of the piston pump 5 will be lower than in the reservoir 11.

At the same time in the upper part of the cylinder under the action of discharging compressed spring 30 of the suction valve 26, the valve opens and water from the sea through the vertical pipe, the intake manifold 32, line 22 and the housing 18 of the valve chest is fed into the cylinder 14.

Next, the above cycle is repeated continuously.

When you change the calculated forces unrest in the direction of increasing the cylinders 7 are starting to come out again, the angle between the movable piping expansion joints 8 increases, the frame 4 floats 2, 3 away from the wall of the breakwater 1, the kinetic energy of the standing wave decreases, the pressure decreases and Vice versa.

In both cases, is the regulation and stabilization of the load.

The use of symmetric floats made in the form of a closed hollow vessel of rectangular cross-section allows to increase the efficiency of tidal hydroelectric power.

The fastening of the vertical frames with floats directly on the coastal gidrotehnicheskaya.

Installing RAM on hydraulic structure can move in the horizontal plane allows you to extend the range of lengths used standing waves.

Implementation of vertical frames movable by hydraulic cylinders allows to regulate and stabilize the load tidal hydroelectric changing the strength of the emotion.
