Description
Technical field
The invention belongs to novel renewable energy technology and field of marine equipment, particularly a kind of vibration float type wave energy apparatus.
Background technique
Along with the increase of the development of World Economics, population, the improving constantly of social life level, the demand of various countries to the energy increases rapidly.In recent years; the driving of, the energy safety of supply increasingly exhausted by fossil energy and protection of the environment etc.; ocean energy cause as one of the essential reproducible energy obtains and develops on a large scale very much, and ocean energy application technology reaches its maturity, and illustrates rosy prospect for the mankind make full use of ocean energy in 21 century.
At present, main in the world wave energy apparatus can be divided into three classes according to its position distribution: offshore type (offshore is more than 2.5Km), offshore formula and bank base formula.Wherein, offshore formula wave energy apparatus receives study widely owing to being easy to the features such as installation and maintenance, construction cost be low.Meanwhile, residing for it, wave energy density in region is relatively high, is not easy again to be subject to the boisterous impacts such as typhoon.In the last few years, this kind of wave energy apparatus obtained larger development.But collapsing force huge under considering the randomness of the specific physical chemical property of seawater and wave and its extreme weather, for being arranged on marine wave energy generating set, engineers emphasis of having to considers stability and the Security of device.While guarantee Wave energy converting device can adapt to different weather conditions, needs investigate the surviving policy and vital capacity that design under extreme weather conditions.
Summary of the invention
Technical problem to be solved by this invention is: the deficiency such as the stability overcoming above-mentioned existing wave-powered energy technology is low, poor stability, a kind of vibration float type wave energy apparatus is provided, the change that it can utilize sea water level to produce with wave transmission, efficiently wave energy is converted into electric energy, be applicable to greater coasting area, for the offshore installations such as Marine Navigating Light, observing station provides electric power, be also easy to direct generation of electricity networking, there is higher reliability simultaneously, be easy to manufacture and install.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of vibration float type wave energy apparatus, comprises generating cabin, float, column, connecting rod, rotating shaft, gear-box and generator, it is characterized in that: device entirety is laid on a foundation at the seabed by column; Install generating cabin above column, generating installs gear-box, driving rack and generator in cabin; Driving rack in generating cabin is connected with float by outer link, and outer link can around the axis of rotation being fixed on generating inside, cabin; One end of driving rack is connected with outer link, and is connected with gear-box input rotating shaft.
Described one vibration float type wave energy apparatus, it is characterized in that: be articulated and connected between outer link and float, outer link and driving rack are also articulated and connected.
Described one vibration float type wave energy apparatus, is characterized in that: installed one group of clockwise ratchet mechanism and one group of counterclockwise ratchet mechanism in gear-box.
Wave energy apparatus by the direct security protection of column on a foundation at the seabed, is applicable to offshore sea waters.The main body of device can adopt prefabricated on the coast, and utilize barge to drag to specified position, submerged is installed.The change of the water level elevation that device mainly utilizes wave to cause, has nothing to do with arrival bearing, is the absorption wave energy apparatus of a kind of point.The number of its float also can rationally increase, to improve the capture rate of wave energy.When stormy waves condition is comparatively severe, can easily float be dismantled and be transported and leave, the Security of ensuring equipment.
When not having wave action, buoyancy and the gravity of float reach state of equilibrium, float transfixion.When wave is delivered to wave energy apparatus, float can move up and down along with the change of water level elevation, and then drivening rod and driving rack are around rotating shaft reciprocating rotation.When crest is by float present position, float is under the acting in conjunction of hydrodynamic pressure and hydrostatic pressure, and the equilibrium of forces suffered by float is broken, and float accelerates to move upward, and pulls outer link to rotate clockwise.Outer link drives driving rack to move in the horizontal direction by articulating point while rotation, promotion driving rack moves right, the motion driven gear case input simultaneously axis of rotation of driving rack, and by gearbox drive to generator, generator rotation sends electric power.When crest continues to front transfer, float is along with the decline of present position water level elevation, start to accelerate downwards, and then drive driving rack to accelerate left by connecting rod, until float is positioned at wave trough position, in this process, driving rack is to left movement, also driven gear case input axis of rotation, sense of rotation is contrary with a upper process, is generated electricity by the work of gearbox drive drive electrical generators.So driving rack enters into a reciprocating circulation along with the effect of wave, tooth bar continuous driven gear case input axis of rotation, gearbox drive makes generator operation output power to generator.Clockwise ratchet mechanism in gear-box and counterclockwise ratchet mechanism can ensure the sense of rotation regardless of inputting rotating shaft, and the sense of rotation of the rotating shaft of generator is all constant, and this arranges the stability and the working life that improve electricity generating device.
The invention has the beneficial effects as follows:
The present invention is applicable to the greater coasting area of wave energy resource compared with horn of plenty, adopts the design of the vibration float type wave energy apparatus of multiple float, can adapt to the incoming wave of all directions; Its electricity generating principle is simple, stabilised efficiency; Electricity generating device is installed on apparatus main body inside, and Security is high; Device is overall, and form is simple, is convenient to manufacture and install.
