Description
Technical field
The invention belongs to novel renewable energy technology and field of marine equipment, particularly a kind of absorption Wave energy converting device of point using two float structure.
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 basic principle that generates electricity: oscillaton water column type, oscillating float type and more waves.Wherein, oscillating float type wave energy apparatus due to its energy conversion efficiency high, various informative, wide accommodation, it is convenient to implement, and obtains investigation and application widely.
Oscillating float type device is the Wave energy electric generator grown up on the basis of oscillaton water column type device.It is placed on the conversion equipment of the cylindrical/spherical shape float in port as wave energy with one, and then change away by being placed on the two times transfer devices such as machinery on the bank or hydraulic pressure, drive motor generates electricity.But, up to now, not yet there is certain oscillating float type wave energy apparatus of report on energy conversion efficiency and Security and overall performance, reach the requirement of business development.
Summary of the invention
Technical problem to be solved by this invention is: the cost overcoming above-mentioned existing wave-powered energy technology is higher, constructional difficulties and the deficiency such as energy conversion efficiency is low, a kind of absorption Wave energy converting device of point using two float structure is provided, the change that it can utilize sea water level to produce with wave transmission, efficiently wave energy is converted into electric energy, for the offshore installations such as Marine Navigating Light, observing station provides electric power, there is higher reliability simultaneously, be easy to manufacture, install and move.
The technical solution adopted for the present invention to solve the technical problems is:
Use the absorption Wave energy converting device of point of two float structure, comprise float, buoyancy generating cabin, connecting rod, gravitational compartment, extra large work basis and anchor chain, it is characterized in that: float is rigidly connected by connecting rod and gravitational compartment; Through the annular pass of presetting in the middle of buoyancy generating cabin in the middle part of connecting rod; Buoyancy generating cabin adopts anchor chain and extra large work basis to be connected and fixed.
Described a kind of absorption Wave energy converting device of point using two float structure, is characterized in that: in-built electrical magnet in connecting rod, and arranges in turn along connecting rod.
Described a kind of absorption Wave energy converting device of point using two float structure, is characterized in that: the upper and lower of connecting rod is all provided with brake baffle.
Described a kind of absorption Wave energy converting device of point using two float structure, is characterized in that: installed many groups coil around annular pass in buoyancy generating cabin.
Use the absorption Wave energy converting device of point of two float structure, its float elevation is near the water surface, and most of main body of electricity generating device is all below the water surface.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.When stormy waves condition is comparatively severe, can easily float be dismantled and be transported and leave, the Security of ensuring equipment.Further, the upper and lower two ends of connecting rod are provided with brake baffle, during to prevent wave excessive, link motion amplitude is excessive causes damage to device.
When wave is delivered to wave energy apparatus, float can move up and down along with the change of water level elevation, so drivening rod and gravitational compartment reciprocating.When crest is positioned at float position, float moves upward due to the higher and water body of present position head, and float self elevation is also higher, and drivening rod and gravitational compartment move upward.Along with crest is to front transfer, the free surface of water at float place changes, and under the acting in conjunction of hydrodynamic pressure and hydrostatic pressure, the elevation of float also changes.When float is positioned at wave trough position, the motion feature of float and connecting rod and noted earlier just contrary, gravitational compartment also moves downward.So, float, connecting rod and gravitational compartment enter into a reciprocating circulation under the effect of regular wave, connecting rod makes the magnetic flux be built in the coil in buoyancy generating cabin change in reciprocating process, according to the law of electromagnetic induction, generation current in coil, and then send electric power.
The invention has the beneficial effects as follows:
The present invention is applicable to the far-reaching sea region of wave energy resource compared with horn of plenty, adopts the design of two float structure, can adapt to the incoming wave of all directions; Its electricity generating principle have employed electromagnet and coil and mutually moves and produce the mode of magnetic flux change, and form is simple, stabilised efficiency; Rotor machine is installed on the inside in buoyancy generating cabin, and Security is high; Wave energy converting device design form is simple, and adaptability is better, is convenient to manufacture, install and transfer.
