FIELD: power industry.
SUBSTANCE: invention relates to the power industry, namely to sea wave energy removal devices in a near-shore area. A combined wave energy converter is made in the form of a hollow reinforced-concrete mass 1 forming a pool having the front (facing to the sea) wall 4 with inlet plate-like valves 8 in the underwater part and an inlet valve in the upper part and a rear wall 6 with an outlet water line and low-pressure hydraulic turbine 11 in the underwater part. The upper valve of the front wall 4 is made in the form of a floating pontoon 9 on a hinged connection, which is inclined inside the pool. On the upper edge of the rear wall there attached by means of a hinge is a flap 12 elevated above the water surface and retained in a vertical position with elastic couplings 13, which is capable of being swung by crests of big waves and has an additional line power takeoff device 14.
EFFECT: invention is aimed at the improvement of the wave energy takeoff efficiency, automatic control and coordination of operation of a combination of different working elements of the device.
The invention relates to the field of energy, in particular to devices for extracting energy from sea waves in the coastal zone.
From a technology known wave power plant on the basis of the tank or basin filled with water through the overflow crests of the waves from the front wall or the hub of energy waves (type OWEC - Overtopping Wave Energy Converter), in particular the TAPCHAN system. When the water level in the reservoir is formed by a head, in which the output channel is formed for leading in action located at it the low-pressure turbine.
The prior art known to the device with the rocking waves sash having positive buoyancy, pivotally connected with the base on the bottom, operate the device PTO (type OWSC - Oscillating wave surge converter), such as the system of "Oyster" (see US 8004105 B2, 07.02.1981, F03B13/12).
The disadvantage of OWEC is low efficiency due to high loss of energy waves at their reflection from the front wall or the movement along the narrowing channel, and when splashing in the pool. In addition, the effective operation of the OWEC device is possible only in a narrow wavelength range. Effective use of the OWSC possible only on large waves, when there is intense swinging sash. In addition, this design is difficult to ensure the safety from the destruction of the storm waves. Also both types of devices are ineffective in areas with significant tidal otlivnye fluctuations in sea level.
Closest to the invention, the technical solution is the device type OWEC with the inlet valve plate over the front wall in the form of hinge plates with positive buoyancy and outlet flow channel with turbo-generator (see EN 2046207 C1, 20.10.1995, F03B 13/26).
The disadvantage of this technical solution are: increased energy losses due to reflection of waves from the front wall at sea; the absence of a rear wall of the basin, the role played by the Bank, which in most cases will lead to a large width of the pool, and the inability to substantially enhance it, therefore, to a small pressure at the outlet.
The task of the claimed invention is to provide the most complete selection of potential and kinetic energy of waves in a wide range of heights and frequencies, including tidal tidal and storm surges, while protecting the shore from storm waves.
The technical result of the invention is to increase the efficiency of extraction of energy from waves in providing automatic control and coordinate the operation of the combination of the various working elements of the device.
This technical result is achieved by a three-tiered system oberaargau waves (in the underwater part near the quiet of the water and above the water surface). The invention consists in the following. Hollow concrete array in the form of pools, fixed on the bottom has a wall that rises above the water. In the underwater part of the front (facing the sea) walls are input valves, ensuring the filling of the basin and reduce the reflection of waves from the wall into the sea. Filling the pool with water also occurs by the movement of waves through the front wall, with the upper part of the floating pontoon on the hinges, playing the role of the upper valve, which passes inside the pool crests of the waves and blocking the reverse flow of water. The rear wall of the basin in the underwater part has a discharge conduit with the low-pressure turbine, running on the generator. On the upper edge of the rear wall on a swivel mounted fold, held vertically elastic links, which swings the crests of large storm waves, transferring the energy to an additional linear device PTO, while reducing the waves in the pool, preventing reverse flow, as well as blocking the path of the storm waves on inland waters.
The coordination of the lower valve and the upper pontoon anterior wall consists of the following. Bottom valves, reducing the reflection of waves and preventing the contraction in the Finance standing waves, provide forward crests of the waves on the top of the pontoon. The simultaneous supply of water to the pool through the lower valve and the upper pontoon automatically ensures the effective slope of the pontoon at the time of the forward wave crest, which leads to an increase in the height of the ridge.
Automatic coordination of the upper pontoon front wall and a sash on the back is the following. Fold with the additional PTO absorbs the energy trapped in the pool waves while reducing reflected waves in the pool and preventing their negative impact on the slope of the pontoon, which provides an efficient forward external waves in the pool and their uptake by leaf.
The essential features characterizing the invention.
Restrictive: the energy Converter of the waves in the coastal zone in the form of a hollow concrete array, forming a pool, with the front (facing the sea) wall with an inlet reed valves in the underwater part and the inlet valve in the upper part, and a back wall with an outlet conduit and the low pressure turbine in the underwater part.
Distinctive: the top flap of the front wall is made in the form of an inclined inside of the swimming pool floating pontoon on a swivel, and on the upper edge of the rear wall by a hinge is attached to the target is and, towering above the water surface and held in a vertical position, elastic ties, able to sway the crests of large waves and having a more linear device PTO.
Significant new features can improve the efficiency of the installation in terms of a wide range of wave heights and variable level by combining multiple means of capture and convert wave energy and their location relative to each other, which ensures consistent operation and automatic control flows, reducing losses due to reflection of waves and protect the coast from storm surges.
The drawing shows a side view of the transducer of energy waves.
The combined energy Converter wave contains an array of giant 1 gravity, which can be made from reinforced concrete and is additionally secured against displacement piles 2 and/or ballast 3. The walls of the array (size 4, side 5 and a back 6 and the bottom 7 form a pool. The front wall has an underwater opening with the inlet reed valves 8, hinged pontoon 9 10 stops. In the back is the outlet from the low pressure turbine 11, the hinged door 12 is held in a vertical position by elastic links 13, the device of the boron power (linear generator) 14.
Device for converting wave energy works in the following way. The rising tide opens the valve 8 in the underwater part of the front wall 4 forming the input flow of water in the pool. The water level in the pool rises, lifting the pontoon 9. At the same time the crest of a wave rolled on the pontoon 9 and then poured in the pool. This pontoon has a slope that increases the height of the rolling crest of a wave. When a large increase in the pool, for example when significant tidal or storm waves, pontoon 9 can take a vertical position. To prevent its rotation in the direction of the sea provided by the stops 10. After passing the top of the wave valves 8 in the front wall is closed because the pressure in the pool at this point exceeds the pressure under the sole of the wave front of the wall. Formed in the pool the water pressure drives the turbine 11 in the rear wall 6 connected to a generator. The crests of large waves, caught in the pool, reject the sash 12, the return of which is in the vertical position, the elastic ties 13. The energy of the movement of the leaf is converted into an electric linear generator 14. To prevent displacement of the installation of extreme waves is provided by the piles 2 and/or ballast 3.
The width and angle of the pontoon when the average level is e water in the pool are selected from the condition of achieving the greatest concentration of energy on the crests of waves. Inlet valves in the underwater part of the front wall to reduce the reflection of waves, prevent the formation of standing waves in front of the wall, than to promote a better roll of the waves and the overflow through the floating pontoon. The shutter on rear wall further reduces the reflection of the waves in the pool and prevents splashing back into the sea, and also protect the coast from storm surges.
To increase the power and education protected from the waves of the waters can have multiple transducers in the form of a breakwater, stretching along the coast.
