Abstract
The invention provides a floating waver power generating device with double floating bodies, comprising a big floating body floating on the sea surface, which is linked to the sea bottom by anchor chain, and on which sliding way is set; small floating body set on the big floating body, which can slide along the sliding way. The upper end of small floating body is connected to the chain and the chain is winded on the chain wheel. The chain wheel is connected with hydraulic and power generating system in the big floating body by clutch. The invention mainly makes use of the relative movement of big and small floating bodies under the waver effect to distill waver energy. The invention can exist in sea as a single body and also exist in sea with multiple devices connected with each other so as to realize the demand of developing oceanic wave energy at a large scale. Because the oceanic wave energy exists in nature and permanently, once the invention device is used, power can be outputted continuously. Compared with common power generating method with exhaust source, the invention has huge developing advantage.
Description
Technical field
The invention belongs to marine energy and utilize technical field, relate in particular to a kind of device that utilizes wave-energy power generation.
Technical background
Wave energy is the renewable energy sources the widest, that energy flux density is maximum that distributes in the ocean, and success and the high efficiency wave energy that utilizes provide electric power to have great significance at seafari, fishery exploitation and ocean military aspect for oceanographic equipment and islander.The floating-type wave energy electricity-generating method is most important a kind of in the offshore exploitation ocean wave energy method, also is the focus of the ocean wave energy of countries in the world exploitation now.Motion buoyancy aid under wave action can extract wave energy, and it is a kind of commonly used and efficient ways in the ocean wave energy development and use that the wave energy that buoyancy aid is extracted is converted into electric energy commonly used.
Summary of the invention
The purpose of this invention is to provide a kind of floating type double-floater ocean wave power generator.
The present invention utilizes buoyancy aid to extract wave energy and the principle that is converted to electric energy realizes that concrete technological scheme is: in the seabed, big buoyancy aid is provided with tilted slideway to the big buoyancy aid that floats on the sea by the anchor chain mooring; On this tilted slideway, settle the little buoyancy aid that can move along slideway, little buoyancy aid upper end connects chain, chain roll can be at the terminal pouring weight that hangs of chain on sprocket wheel, and sprocket shaft joins by clutch and hydraulic pump shaft, sprocket wheel sense of rotation when setting little buoyancy aid and moving downward is for just, clutch separation, anti-clutch closure then, oil hydraulic pump connects accumulator by oil circuit, accumulator connects oil hydraulic motor, and oil hydraulic motor connects generator.Said system can be divided into two parts generally, and a part is made up of two buoyancy aids of size, and another part is made up of hydraulic pressure and power facility.These two-part lump together by chain, sprocket wheel and clutch pack.
Working principle of the present invention is: big buoyancy aid is positioned over the sea, and pass through the anchor chain mooring in the seabed, the therefore big motion of buoyancy aid under wave action is restricted, motion amplitude is less: place the little buoyancy aid that can move along slideway on the tilted slideway of big buoyancy aid, but it is along the unrestricted motion of slideway direction, motion amplitude is bigger, so just can utilize the relative movement of large and small buoyancy aid under wave action to extract wave energy.When coming wave, little buoyancy aid freely moves upward under wave action, clutch separation, and the pouring weight of chain end relies on its gravity rolling to connect the chain of little buoyancy aid upper end, and the potential energy of little buoyancy aid increases; When wave was decorporated, little buoyancy aid spurred chain and moves downward under action of gravity, the clutch closure, and sprocket wheel drives oil hydraulic pump. and oil hydraulic pump pump pressure hydraulic oil is to accumulator, and the potential energy of little buoyancy aid is converted into the hydraulic pressure energy.Little buoyancy aid periodic drive oil hydraulic pump pump pressure hydraulic oil as described above is to accumulator, when energy storage pressure reaches certain value, the oil circuit switch opens, hydraulic oil impacts oil hydraulic motor in the accumulator, hydraulic pressure can be become motor mechanical energy, and hydraulic motor-driving generator can produce electric energy.
The inventive method mainly utilizes the differences in motion of two floating bodies under wave action to extract wave energy, and the wave energy that extracts is converted to electric energy.Little buoyancy aid extraction wave energy is the first step in the above-mentioned transfer process, because wave energy is unsettled, it is little when big when coming wave, and when little buoyancy aid directly was subjected to wave stroke, its motion may be too violent, easily system architecture is damaged, therefore when utilizing the mechanical energy of little buoyancy aid, the process of avoiding directly utilizing little buoyancy aid to move upward is done work, but utilizes the downward movement process of little buoyancy aid to do work, promptly rely on the gravity acting of little buoyancy aid, this acting process is comparatively steady.By little buoyancy aid mechanical energy in the transfer process of electric energy, mainly utilize hydraulic system to transmit and stable energy.The accumulator that uses in the hydraulic system plays accumulation of energy, voltage stabilizing, and the hydraulic oil after accumulation of energy, voltage stabilizing impacts oil hydraulic motor, and oil hydraulic motor drives generator, finally realizes by the conversion of unsettled wave energy to stable electric energy.
Big buoyancy aid of the present invention is energy transfer mechanism still not; it also is the carrier of whole system; all mechanisms of system all are placed on the big buoyancy aid or its inside; therefore the integrity of system is very good; this helps designing the strong structure of autoprotection ability; can effectively reduce the maintenance difficulties of device, reduce maintenance times, improve the Security of device greatly.Because of mechanism's compactness of device, it is made and installation process is simple and easy to realize.Compare with other wave energy generating sets, the inventive method embodiment is all having an enormous advantage aspect manufacturing and the construction.
Described hydraulic pressure and power facility can adopt various ways, comprise disclosed technology in the prior art.
Apparatus of the present invention can be present in the ocean by monomer, also multiple arrangement can be interconnected, and realize the needs of large-scale development ocean wave energy.The electric power that this device sends can be to power supplies such as oceanographic instrumentation equipment such as navigation mark lights, also can be by submarine cable with power delivery to island and bank in the neighbourhood.Because of ocean wave energy is that nature generates and permanent the existence, so in a single day apparatus of the present invention come into operation, output power is compared with conventional consumes resources type generation mode endlessly, and apparatus of the present invention have great advantages for development.
