The invention relates to hydraulic structures and is intended for:
coastal protection from the damaging effects of the waves of the sea;
conversion EN is a Finance energy of sea waves, converted into electric current;
protection from waves and wave power station to provide electricity production units, artificial Islands and other structures in the sea.Known hydraulic structures and devices designed for protection from the effects of the waves of the banks and fences ports and harbours and converting the energy of sea waves into electrical current (see U.S. patent N 4.263.516 and N 3.983.404 on CL 290-54 and and.with. USSR N A in class. F 03 B 13/12).Known hydraulic structures the closest to the technical nature of the present invention is a breakwater and the electricity generator (US patent N 4.263.516).This construction serves to protect the shores and harbours and is a generator of electric current, which is driven by the energy of the waves and running in periodic mode, due to the periodicity of the wave process.Incident on the front inclined surface of the structure, the wave reaches a height-dependent it contains kinetic energy. During rollback, the water opens located on the inclined outer surface of the breakwater closures and rushes through the channels located in the stronger surface of the breakwater rushes in the opposite direction, towards the next oncoming wave, and when the meeting it absorbs part of its kinetic energy, which reduces the coefficient of performance (COP) of the device.The objective of the invention is to provide such a construction of the breakwater modular type converters the energy of the sea waves, which, replacing the supposedly trustworthy would protect the waters of the harbour, beach and other objects in the sea from the damaging effects of the waves and at the same time would provide a high efficiency of energy conversion in continuous mode at periodic wave impact.This technical result is achieved by the fact that in the construction of the breakwater front incident wave is divided into two streams moving in offline sleeves or channels, one of which is straight, operating in accordance with a periodic mode wave of the sea process, and the second channel
pressure provides the lagging phase of the second stream from the first so that the sum of the phases of the network resulting in a continuous process of energy conversion dismal waves into electric current, and the mass of water moving wave compresses the air enclosed in the water intake channel of the breakwater, and air piping, and Stepanova channel, and the mass of water flow consistently served on the appropriate turbine common generator of electric current.Hydraulic structure, which serves to protect the waters of the harbour, beach and other structures in the sea from the damaging effects of sea waves, consists of a number of modules of the breakwater, located on the external border of the harbour so that their front part facing the open sea, and back to the harbour.In Fig. 1 shows a longitudinal vertical section "a-a" passing through remoteservicename the channel system of Fig. 2 a longitudinal vertical section B-B ' passing through the pneumohydraulic system of channels; Fig. 3 is a horizontal section "C-C", passing over the ramp 1, the nozzle channel 2, vulnerablilities partition 13, the flow channel 3, the turbine 8, a drain channel 6 on the one hand; outlet channel 5, the turbine 9, the drain channel 7 on the other hand, common to both turbines generator of electric current 11; Fig. 4 the float device of the rotary mechanism of Fig. 5 and 6, the action of the float swivel mechanism and the position of the gate 21 when approaching and passing through a flow channel 3 mass of water Mor sea side; in Fig. 9 the sequence of the flow of water and air and the operation of the bypass valve.The breakwater with the transformation of the energy of the waves from the sea is the ramp 1, the front part of which is located below sea level. Ramp 1, rising gradually above the sea level goes in the bottom part of the water intake nozzle channel 2 having side walls and ceiling. In the middle part of the intake channel 2 is rotatable gate 12, a hinge mounted on the ceiling. For the working area of the gate 12 is a vertical longitudinal vulnerablitiy partition 13 dividing the mass of water rising wave into two streams. Channel 2 with the gate 12 has a bias towards the harbour.On one side of the partition 13 in the channel 2 is the valve 14, the rotary mechanism 16 which float 17 is used to control the operation of the gate 21, which is located at the beginning of the flow channel 3. The gate 21 in the closed position prevents the flow of air blown by the wave of water intake channel 2 in the flow channel 3. The air displaced by the water enters the air pipe 27 through the float valve 26, and after emptying the discharge channel 4 of the air (or the mass of water of the next wave) from plukovii valve 26 is closed, blocking the access of water into the air pipe 27; float 17 of the swivel mechanism 14 POPs up, opening the gate 21, and the flow of water through the flow channel 3 is directed to the blades of the turbine 8. Giving energy of the wave through the turbine 8 of the generator 11, the water enters the waters of the harbour through the drain channel 6.On the other side of the partition 13 to the intake channel 2 adjacent upward at an angle to the horizontal discharge channel 4, in the upper part of which is a pneumatic energy Converter 10, and in the lower part there is a bypass valve 15, in the working area which is located outlet opening of the channel 5, the feed water from the channel 4 on the blades of the turbine 9 and then into the waters of the Harbor. Turbines 8 and 9 are symmetrically from two sides attached to the shaft of the electric generator 11.In Fig. 4 shows the valve device 14 with float swivel mechanism, which is shown in Fig. 5 and 6. The valve 14 consists of a gate 21, the upper part of which is hinged to the longitudinal partition 13 and the opposite wall of the intake channel 2. The gate 21 has two sides coaxially spaced and rigidly connected to a toothed sector 20, in Threepenny axis on the longitudinal partition 13 and the wall of the channel 2, and the long arms of the levers 18 are rigidly connected with the transverse float 17.In Fig. 7 shows a cross-section of the bypass valve 15, and Fig. 8 view of the valve 15 from the sea. Design by-pass valve 15 consists of a pie plate 23, which provides the rigidity and strength of the structure and placed at equal distances from each other; a solid plate 24 on the upper surface of which is rigidly fixed to one edge of the sector plate 23; the valves 25, hinged at the edge of the other of the sides of the pie plate 23 so that the blades 25 may be opened only in one direction, and in close position, they form a waterproof surface. The bypass valve 15 is hinged to the side walls of the pressure channel 4 at the lower edge of the opening end discharge channel 5.Converting sea wave energy in the construction of the breakwater is performed in the following way.Rolling and moving along the ramp 1 wave by analogy with shallow waters gets great height and steepness and is voenoplennih tapering channel 2. The higher and steeper the wave, the sooner there will be a complete overlap of the weight of the water section of the channel 2 and the greater amount of air will be in free space from vny air pump, receiving acceleration due to narrowing of the nozzle channel 2, driving before him and compressing the air. Air pressure, and then water gate 12 is opened and remains open until the pass is complete the whole mass of water.As the gate 21 and the flow channel 3 is closed, air is drawn through the float valve 26 in the air pipe 27, and in the absence of water in the pressure channel 5 air or a mass of water of the next wave pressure on a solid plate 24 (Fig. 7 and 8) by-pass valve 15 and translate it into a position where blanking plate 24 covers the outlet opening of the channel 5, and shutters 25 under the pressure of the open air and pass into the discharge channel 5 air, and then water, as shown in Fig. 9 POS. a), b) and C). The air flow channel 4 is supplied to the turbine pneumatic energy Converter 10, bringing it in motion, and the exhaust air goes into the environment. If pressure channel 4 will be neoprenanzug, the bypass valve 15 will be opened and air will enter the pipe 27, and the water from channel 2 will flow in the flow channel 5. The bypass valve 15 is opened only in the absence of water in the pressure channel 4. Following the air mass of the water, passing the gate 12, the partition 13 divides the tide lever 18 about the axis 19. The short arms of the levers 18, having the form of a gear sector and located in engagement with a toothed sector 20, rigidly connected with the gate 21, turn the gate 21 and press it to the floor of the channel 3, and the water gained access in the flow channel 3, is directed to the blades of the turbine 8 and, handing them their energy, through the drain channel 6 enters the waters of the harbour. After passage of the wave front of the float 17 is lowered, closing the gate 21 channel 3.The left stream of water, moving air reaches the discharge channel 4 levels corresponding to the contained quantity of kinetic energy, and then under the action of gravitational forces changes the direction of flow in the pressure channel 4 on the reverse, going from channel 4 water produces negative pressure and the external environment of the air enters the turbine pneumatic energy Converter 10, while continuing to rotate it, and then the top gets in abarognosis pressure channel 4.After passage of the wave front on the water intake channel 2 gate 12 is closed. The remainder of the mass of water that are not included in the discharge channel 4, enters the rollback. But as the gate 12 is closed, the rollback may not go towards the next wave and at a meeting with her will repay the hydroturbine 8.After the withdrawal of water from the water intake channel 2 gate 21 blocks the regular flow of air in the flow channel 3.The second phase of the energy conversion dismal wave starts to work after the first phase since changes to reverse the direction of water flow in the discharge channel 4.Under its own weight and the pressure of the water column in the pressure channel 4 fold 25 is closed and the bypass valve 15, as shown in Fig. 9 POS. g), d) and e), is translated in a position where solid plate 24 closes the cross section of the discharge channel 4, and the entire stream of water rushes into the open aperture of the outlet channel 5 and then enters the blades of the turbine 9, after which the waste water through the drain channel 7 enters into the waters of the Harbor.During the passage of the mass of water in the idler channel 5 the second phase of the energy conversion is nearing completion, and at this time to allow the receiving channel 2 receives the next incoming wave and begins a new cycle of energy conversion. 1.
