The invention relates to hydropower, namely the use of energy tidal flow arising on the shores of seas, oceans and other large bodies of water, natural or artificial origin.

There are hydroelectric, using the power of tidal flow. The device is through the axis of the platform with sliding panels and located outside of this zone the building, which set the vertical air cylinders with pistons connected through a manifold to an air turbine and electric generator. The movable end of the platform and facing upwards, the piston rods are connected by multiple cables (number of cylinders), spanning the blocks provided on the ends of the horizontal traverse and vertical posts to which the lower stationary beam attached at its middle part. The rack, in turn, is fixed in the upper part nearest to the sea wall of the building. In the initial position the platform under the weight of the pistons rotated by some angle around the horizontal axis counterclockwise relatively calm sea surface. When working stroke under the weight Nakata her direct tidal flow (forward), the platform is rotated clockwise, and the pistons in the cylinders rise, squeezing contained air, which flows into the turbine causing it to spin.

Due to fluctuations in the strength of tidal flow building with air cylinders, turbine and generator should be located at a considerable distance from the water edge at a calm sea. The use of very long horizontal traverse for the OS leads to lower reliability of tidal hydroelectric power. This disadvantage is eliminated in the surf hydro turbines, working directly on the sea water coming under pressure from reciprocating pumps driven by tidal flow. Known tidal hydroelectric contains swinging around a horizontal axis, partially submerged blade and located above the level of the water piston pump, the turbine and generator. The blade is kinematically connected with the piston of the pump with the shaft mounted thereon a lever and crank. The pump is connected with the sea and the turbine. Under the action of direct tidal flow (forward) the blade is deflected through the shaft, the lever and the crank actuates the pump. Under the action of the reverse tidal flow (rollback) the blade is deflected in the opposite direction. The complexity of the kinematic connection between the oscillating vane and piston pump.

The aim of the invention is to simplify the design and increase the reliability of tidal hydroelectric power.

This goal is achieved by the fact that tidal hydroelectric containing the blade, swinging around a horizontal axis piston pump and water turbine with generator blade and pornevo

The working surface of the blade can be made variable by means of a power cylinder.

The location of the vane and piston pump below the water surface and the execution of them swinging around a vertical axis to simplify the kinematic connection between the vane and piston pump.

The working surface of the blades is variable by means of a power cylinder provides stabilization of the load tidal hydroelectric changing the force of the surf.

In Fig. 1 shows a General view of tidal hydroelectric power plants in the initial position, plan, and Fig. 2 - section a-a in Fig. 1; Fig. 3 - section b-B in Fig. 2; Fig. 4 is a General view of the piston of the pump section.

Tidal hydroelectric power plant consists of two reinforced in the surf zone at some distance from each other vertical supports 1, 2, to one of which is below the level of the water surface is hinged swinging the blade 3, and another rocking piston pump 4, a rod which, in turn, pivotally connected with the blade. Above the level of the water surface on the vertical supports 1, 2 mounted on the platform, on which the turbine 5 connected with the use of a compensator 6 porcheville the direction of forward and reverse tidal flows (forward and back), prevailing at the place of installation of hydroelectric power. Vertical supports 1, 2 are intended for articulated mounting underwater swinging blade 3 and the piston pump 4, and mounting over-water work site for installation of the turbine 5 and the generator 7 and are piles of arbitrary cross-section, for example round.

Bearing 1 for fastening the blade surface has height two pairs of horizontal arms with coaxially arranged on the same vertical axis holes for swivel with corresponding brackets swinging blade 3 and the bearing 2 for fastening the piston pump 4 - one pair of horizontal brackets.

Swinging the blade consists of a vertically arranged stationary and movable relative to each other plates of rigid construction and of the power cylinder 8 and is intended for the perception of pressure forward and reverse tidal flows and the transfer of its porshneva pump 4.

The fixed plate is arbitrary, for example a rectangular shape in plan with one hand has the height of two horizontal bracket coaxially spaced holes for swivel support 1, and the media for longitudinal movement of the movable plate along the surface of fixed and are simultaneously latches from moving in the transverse direction under the action of gravity, thanks to both plates under pressure tidal flow work as a whole.

Movable plate on one side is located in the middle of the height of the horizontal bracket with a hole for the swivel rod piston pump 4.

The power cylinder 8 is designed to change the working surface of the swinging blade 3 by the longitudinal displacement of the movable plate and is located on the fixed plate on the side opposite porshneva pump 4. The housing of the power cylinder is attached to a fixed plate of the blade, and the end of the rod with the piston - mobile.

Piston pump 4 consists of a cylinder 9 with the cover 10, the piston 11 with the rod 12, the housings 13, 14 valve boxes with lids 15, 16, pipe 17, 18, Poppet inlet valves 19, 20 and injection valves 21, 22 and springs 23, 24, the bracket 25 and the discharge manifold 26.

In horizontally placed cylinder 9, the front end is open and provided with a flange for securing the cover 10 and the side surface of the vertical support 2 has a bracket with a hole for pivotally mounting to the support.

On the lateral surface of the cylinder by diameterand boxes.

For mounting of the piston 11 with the rod 12 on the cylinder has a flange cover 10. Pass the rod into the cylinder 9 through the hole with a gland located in the center of the lid.

Cylinder for alternate connection with the sea, and diversion of water under pressure in the discharge manifold 26 is provided with two valve boxes located in the area of the window.

The housings 13, 14 valve boxes made in the form of horizontal rectangular prisms, which side are bottom and on the opposite side opened and divided into two equal parts by vertical partitions. Open and closed ends of the housings are equipped with flanges for fastening the covers 15, 16 and attached to the cylinder 9.

For mounting the suction valves 19, 20, injection valves 21, 22 and springs 23, 24 in the housings 13, 14 are flanged covers 15, 16.

All flanged joints around the perimeter of the abutment and vertical partitions from the lids sealed with elastic strips. In the front side walls of the housings 13, 14 to the right of the vertical partitions has one hole for connecting the valve boxes of the sea, and in the bottom of the interior cavity of the cylinder. Similar holes in the side art is through pipes 17, 18 with a pressure manifold 26, and diversion of water under pressure from the internal cavity of the cylinder 9. The holes in the bottom of the hull valve boxes closed Poppet suction valves 19, 20 and injection valves 21, 22.

Pressing of the suction valves to the input openings are made by means of springs 23, one end of the fixed with washers and cotter pins on the valve stems 19, 20, and the other resting in the bottom of the housing 13, 14.

Pressure injection valves to the input holes is carried out by means of springs 24, resting at one end in a plate valves 21, 22, and the other in the cover 15, 16 valve boxes.

Inside the cylinder 9 is a piston 11, which is fixedly mounted in the middle of the left thickened portion of the stem 12 and can be moved reciprocating under the action of swinging the blade 3. The thickened portion of the stem on both sides of the piston are stops limiting the movement of the piston 11 in the area of the window.

At the end of the right side of the shaft 12 there is a thread for fixing the bracket 25 with two coaxially spaced holes. The bracket serves to swivel rod with a horizontal bracket movable plate swinging blade 3.

Discharge manifold is designed to collect water under pressure coming from the internal cavity of the cylinder through the pipes 17, 18, and is closed at both ends of the pipe with the outlet pipe, located in the area of the bracket to minimize the angles of rotation in the hinge expansion joint in the swing cylinder around the vertical supports (2).

The compensator is chetyrehsharnirnymi pipe with two end and two intermediate hinges.

Pipe expansion joints are at right angles , and vertices which are intermediate hinges, so that they can rotate around hinges, changing angles and simultaneously the distance between the leaf hinges.

Compensators are used to swivel the discharge manifold 26 of the piston pump 4 turbine 5 to reflect changes in the distance between them on the value of the arc described by the inlet pressure manifold during operation tidal hydroelectric power.

The turbine 5 is connected to the generator 7, which is designed for poluchenii movable plate swinging blade 3 is partially extended from the fixed plate by an amount equal to half the stroke of the power cylinder; a vane rotated by some angle, for example /2, in the direction of the incident direct tidal flow (forward); rod 12 of the piston pump 4 is fully extended from the cylinder 9 and the piston 11 is in its extreme right position; the pump compensator 6 and the turbine 5 is filled with water.

When interacting oscillating blades with a moving mass of water kinematic energy of the waves is converted into pressure, which turns the blade around its vertical axis in a clockwise direction, and the latter through the piston rod moves the piston pump to the left and simultaneously rotates the pump around its vertical axis in a clockwise direction with the phase angle (the angle of rotation of the pump at any given moment is less than the angle of rotation of the blade). Upon increase of pressure in the lower part of the cylinder 9 is compressed spring 24 of the injection valve 22, the valve is opened and water under pressure through the housing 14 of the valve chest, the pipeline 18, the discharge manifold 26 and the compensator 6 is supplied to the turbine 5, causing rotation of the turbine and associated electric generator 7. At the same time in the upper part of the cylinder under the action of discharging compressed spring 23 vsasyvauschie orapki enters the cylinder 9.

After passing direct tidal flow swinging the blade 3 is rotated by some angle, for example /2, in the direction of the incident inverse tidal flow (rollback), i.e., the full angle of rotation of the blade is , the rod 12 of the piston pump 4 is fully retracted into the cylinder 9 and the piston 11 is in its extreme left position.

When interacting oscillating blades with a moving mass of water kinetic energy of the waves is converted into pressure, which turns the blade around its vertical axis counterclockwise, and the latter through the piston rod moves the piston pump to the right and simultaneously rotates the pump around its vertical axis counterclockwise with the phase angle (the angle of rotation of the pump at any given moment is less than the angle of rotation of the blade).

Upon increase of pressure in the upper part of the cylinder 9 is compressed spring 24 injection valve 21, the valve is opened and water under pressure through the housing 13 of the valve chest, the pipe 17, the discharge manifold 26 and the compensator 6 is supplied to the turbine 5, causing rotation of the turbine and associated electric generator 7. At the same time in the lower part of the cylinder under the action of the bit is in the side wall of the housing 14 of the valve chest enters the cylinder 9.

Next, the above cycle is repeated continuously, and the blade 3 and the piston pump swinging each around its vertical axis.

If you increase the force of the waves above the estimated movable plate swinging blade 3 begins to move inside the fixed plate by means of a power cylinder, the working surface of the blade decreases and Vice versa.

In both cases, the breaking load of hydroelectric power is stabilized.

The location of the vane and piston pump below the water surface and the execution of them swinging around a vertical axis simplify the design and increase the reliability.

The working surface of the swinging blades is variable by means of a power cylinder stabilizes the load tidal hydroelectric power.
