The internal cavity housings connected in parallel to the manifold through a check valve. 2 Il. The invention relates to hydropower, and more specifically to hydroelectric plants, using energy undertow and reflected waves occurring on the coastal hydraulic structures, such as protective breakwaters ports located near the shores of seas, oceans and other large bodies of water, natural and artificial origin.Known tidal hydroelectric installed on the breakwater, contains Anoprienko device, the turbine and associated electric generator.Anoprienko device is a series of spherical ".Floats actuate spring-loaded pistons moving in the cylinders, also attached to the frame and provided with holes to fill them with water and telescopic discharge pipe for supplying water under pressure to the turbine.The last set 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 hinges with the help of levers floats are in the leftmost position.Under the action of incident breaking waves floats closer to the wall of the breakwater and, compressing pistons water in the cylinders, pump her telescopic pipes up to the turbine, which rotates actuates a generator.The complexity of the design due to the presence of spherical floats, levers with hinges, cylinders with spring-loaded pistons, movable 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 of resonant type, octanophenone and water turbine with generator. Voenoplennih the body in the form mounted on the horizontal guide platform with a pendulum, the upper part of which one side is connected with a spring, and on the other with the rod of the piston pump double-acting hinge attached to the platform.Upon the occurrence of a standing wave the pendulum swings, compressing the spring, and simultaneously moves the piston pump, the water from which is supplied under pressure to the turbine.With the disappearance of the standing wave pendulum under the influence of spring returns to its original position, and the piston pump is the second stroke.For movement of the pendulum when the change of the wavelength of the incoming waves voenoplennih body connected to the cylinder.The possibility of jamming of the pendulum decreases the reliability, and the presence of moving parts in Anoprienko body complicates the design of the device.The aim of the invention is to increase the reliability of tidal hydroelectric and simplifying its construction.The aim is achieved in that in the known tidal hydropower, installed on the coastal hydraulic structure containing Hydrator - Bina with EAP with piping and check valves, connected to the turbine, as Anoprienko body are at least two installed along waterworks submerged under the water level of the box-shaped enclosure with Windows in the bottoms, with the internal cavity housings connected in parallel to the manifold through a check valve.Box enclosures can be made movable by hydraulic cylinders.Application in Anoprienko body several submerged under the water level of the box-shaped buildings with Windows bottoms can improve the reliability of tidal hydroelectric power.The exception to Anoprienko body of moving parts allows to simplify the design tidal hydroelectric power.The implementation of the box-shaped housings movable by hydraulic cylinders allows the regulation and stabilization of the load tidal hydroelectric changing the force of the waves.In Fig. 1 shows a General view of the surf hydro in plan; Fig. 2 - section a-a in Fig. 1.Tidal hydroelectric contains the breakwater 1 (existing), a box-shaped housings 2, 3 stops 4, frames 5 and 6 cylinders, pipeline is Pier 1 is an existing protective breakwater sea port, which is under construction for protection against wind waves the waters of the inshore moorings, approaches, channels and gateways, or other coastal waterway.The breakwater is used for the formation of a standing wave, fastening with a certain step length on the open sea side of the breakwater box-shaped housings 2, 3 and install it on the turbine 13 to the electric generator 14.A box-shaped housings 2, 3 are designed to convert the kinetic energy of the standing wave in the hydrostatic pressure of the water and made in the form of submerged under the water level closed from both ends of the elongated hollow casings of rectangular cross-section.The adopted form of the buildings eliminates accidental rotation in the frame 5 around a horizontal axis under the influence of the rolling surf and reflected waves.In the bottom of the box-shaped housings 2, 3 from pier 1 has a rectangular window for the passage of the standing wave located between the U-shaped arms of the frames 5 and on the opposite side, in the middle there is a hole to drain water under pressure through the pipes 7, 8, return the memory to the outside of the buildings from the side of the rectangular Windows are attached to the lugs 4, which, resting on the frame 5, to prevent lateral displacement of the box-shaped housings 2, 3 along the breakwater 1 under the influence of the surf and also serve as guides when they move with the help of hydraulic cylinders 6 perpendicular to the breakwater to regulate and stabilize the load when changing power of excitement.On the sides of buildings, in the middle, opposite the breakwater 1, there are tabs with holes for the hinge connection with the cylinders, through which a box-shaped housings 2, 3 can move in reciprocating.The buildings are located along the length of the breakwater with a certain step, which allows to minimize the pulsation pressure of the water in the reservoir 12 by sequential actuation and automatic shutdown box-shaped housings 2, 3 as you move the standing wave along the breakwater.Frame 5 are used for fixed mounting housings in the area of education of the standing wave generated on the breakwater 1 from the open sea, and the ability to move a box-shaped housings 2, 3 perpendicular to the breakwater to regulate and stabilize the load tidal hydroelectric power.Each frame Kostoev breakwater 1, and on the other, are interconnected lengthwise and form a rigid spatial structure.In the middle of the median longitudinal relation to the frame 5 is hinged to the housing of the hydraulic cylinder 6.The distance between the arms is slightly greater than the distance between the stops 4, available at box-shaped housings 2, 3, and the height of the brackets in the light is slightly greater than the height of buildings to allow movement of the latter along the frame 5 with the help of hydraulic cylinders.Swivel cylinders 6 with 5 frames and rods - box housings 2, 3 prevents misalignment of the cameras in the U-shaped brackets of frames with the movements.Check valves 9, 10 are mounted on the pipes 7, 8 so that water flows only in the direction of the box-shaped housings 2, 3 via the collector 12 in the turbine and are designed for continuous water flow in the turbine 13, regardless of what the buildings are currently under the influence of the standing wave, as well as prevent inadvertent draining the system when stopping.The collector 12 collects water under pressure coming from the box-shaped housings 2, 3, and feed it into the turbine 13 and represents the th which he through the compensator 11 is connected with a non-return valve.Expansion joints are designed to compensate for the reciprocating movement of the box-shaped housings 2, 3 and rigidly United with them pipes 7, 8 and non-return valves 9, 10 relative to the manifold 12 with the regulation and stabilization of the load tidal hydroelectric power.The joints 11 are located in a vertical plane transenergie pipelines with two end and one intermediate hinges.Pipe expansion joints are located at a certain angle , the apex of which is located intermediate the hinge, so that they can rotate around the hinge, changing the angle and the distance between the leaf hinges.In order to fully convert the kinetic energy of the standing wave and the effective operation of the turbine 13 of the bottom of the box-shaped housings 2, 3 are submerged under the water level to a depth that is equal to the estimated height of the tidal wave and turbine is installed on the breakwater 1 below the crest of the resulting standing wave.The collector 12 is connected to the turbine through a vertical pipe.The turbine 13 is connected to a generator 14, which is used to receive power is rudovanie in addition to the above-water part of the breakwater 1 and installed the turbine 13 to the electric generator 14 is submerged under the water level at a calm sea and filled with water.The water pressure in the box-shaped housings 2, 3 is equal to the external hydrostatic pressure at the depth of installation of boxes.The cylinders 6, half extended, and United with them a box-shaped housings 2, 3 at the same distance does not reach the wall of the breakwater.Check valves 9, 10 under the pressure of the water in the turbine 13 and a vertical pipeline, closed.In the process of formation of the rolling surf and reflected from the breakwater 1 waves in the area of the box-shaped body 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 available at the bottom of the box-shaped body of the breakwater rectangular window, standing wave passes inside of the closed housing 2, resulting in the velocity head of the water is converted to a pressure exceeding the pressure in the box-shaped housing 3, which is equal to the external hydrostatic pressure at the depth of installation.Under the action of differential pressure water through a special hole in the bottom of the box-shaped body 2 is held in a horizontal pipe 7 opens the check valve 9 and through the comp generator 14.At this time, the check valve 10 remains in the closed position as the pressure in the reservoir 12 is larger than the box-shaped housing 3.As you move the standing wave along the breakwater 1 from the zone location of the housing 2 in the area of the body 3 upward, the water passes into the housing 3, where the velocity head of the water is converted to pressure in excess of at some point in time, the pressure in the box-shaped body 2, which is determined by the decreasing pressure of the standing wave and its disappearance becomes equal to the external hydrostatic pressure at the depth of installation.Under the action of differential pressure water through a special hole in the bottom of the box-shaped body 3 is held in a horizontal pipe 8 opens the check valve 10 and through the compensator 11, the collector 12 and the vertical line enters the turbine 13, causing rotation of the turbine to a generator 14.Next, the above cycle is repeated continuously.When you change the calculated forces unrest in the direction of increasing or reducing the load tidal hydroelectric cylinders 6 are starting to pull me in, the angle between the movable TRU the Fuzhou water, included in the buildings is reduced, the pressure decreases and Vice versa.In both cases, is the regulation and stabilization of the load.Execution Anoprienko body in the form of at least two installed along waterworks submerged under the water level of the box-shaped buildings with Windows in the bottoms with the parallel connection of the internal cavities of the housings to pipeline manifold through a check valve increases the reliability of the tidal work hydroelectric power.The exception to Anoprienko body moving parts simplifies the design tidal hydroelectric power.The implementation of the box-shaped housings movable by hydraulic cylinders allows the regulation and stabilization of the load tidal hydroelectric changing the power wave deposits.
