Description
Technical field
The invention belongs to novel renewable energy technology and field of marine equipment, particularly a kind of wave energy apparatus of swing power generation.
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 wave energy apparatus of swing power generation is provided, the change that it can utilize seawater velocity to produce with wave transmission, efficiently wave energy is converted into the kinetic energy of pendulum plate, and then 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, also be 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 wave energy apparatus for swing power generation, comprises generating cabin, pendulum plate, top board, waterwall, electromagnet, coil and cable.It is characterized in that: device entirety is placed in seabed by waterwall; Between waterwall, rotating shaft is installed, and pendulum plate has been installed in rotating shaft, pendulum plate is provided with electromagnet; Top board is laid on the top of waterwall, and the centre of top board is provided with generating cabin towards the direction of rotating shaft.
The wave energy apparatus of described a kind of swing power generation, is characterized in that: pendulum plate is hollow structure, and center of top installs electromagnet.
The wave energy apparatus of described a kind of swing power generation, is characterized in that: generating cabin is arranged on top board, and is symmetrically distributed in the both sides of electromagnet.
The wave energy apparatus of described a kind of swing power generation, is characterized in that: the inner cloth in generating cabin is placed with circular coil.
Wave energy apparatus is directly laid on a foundation at the seabed by waterwall, 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 reciprocating kinetic energy of the water body that device mainly utilizes wave to cause, the size of its pendulum plate also can rationally increase, to improve the capture rate of wave energy.When stormy waves condition is comparatively severe, can easily pendulum plate be dismantled and be transported and leave, the Security of ensuring equipment.
When not having wave action, buoyancy and the gravity of pendulum plate reach state of equilibrium, pendulum plate transfixion.When wave is delivered to wave energy apparatus, pendulum plate can along with the change of water volume flow rate around axis of rotation, and then be with the electromagnet at movable pendulum plate top reciprocating.Along with the motion of electromagnet, the magnetic flux in the toroidal inductor in generating cabin changes, and then generation current.Multiple wave energy apparatus can be laid side by side, to improve total output of transformation of energy at offshore.Meanwhile, the top board of wave energy apparatus can also as the operating platform of other activities in production, or provides the harbor for ship.
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 wave energy apparatus of the swing power generation of single pendulum plate, can adapt to various types of incoming wave; Its electricity generating principle have employed the mode of electromagnetic induction generating, and form is simple, stabilised efficiency; Device integral form is simple, and Security is high, is convenient to manufacture and install.
