Description

A kind of many float types wave energy apparatus utilizing gas-turbine
Technical field
The invention belongs to novel renewable energy technology and field of marine equipment, particularly a kind of many float types wave energy apparatus utilizing gas-turbine.
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 many float types wave energy apparatus utilizing gas-turbine is provided, the change that it can utilize sea water level to produce with wave transmission, efficiently wave energy is converted into air pressure energy, and then be 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 direct generation of electricity networking is easy to, 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:
Utilize many float types wave energy apparatus of gas-turbine, comprise generating cabin, float, column, connecting rod, rotating shaft and air pressure generating apparatus, it is characterized in that: device entirety is laid on a foundation at the seabed by column; Install generating cabin above column, generating installs air pressure generating apparatus in cabin; Air pressure generating apparatus 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; Inner link one end and outer link are articulated and connected, and the other end is connected with the piston hinge in air pressure generating apparatus, and piston promotes gas flow in pressure chamber and drives gas-turbine generating.
Described a kind of many float types wave energy apparatus utilizing gas-turbine, is characterized in that: the two ends cloth of passage residing for piston is placed with brake baffle.
Described a kind of many float types wave energy apparatus utilizing gas-turbine, is characterized in that: in pressure chamber, cloth is placed with two groups of air inlets, outgassing nonreturn valve.
Described a kind of many float types wave energy apparatus utilizing gas-turbine, is characterized in that: multiple float shares a main air flow passage and gas-turbine.
Wave energy apparatus is directly laid on a foundation at the seabed by column, 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 piston 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 inner link to move in the horizontal direction by articulating point while rotation, be connected to the piston also horizontal motion thereupon of inner link one end, the motion of piston drives the gas flow in pressure chamber simultaneously, left side breather check valve is opened and air inlet, right side outgassing nonreturn valve is opened and is given vent to anger simultaneously, and gas flow into main air flow passage and drives gas-turbine work to generate electricity.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 piston to accelerate, until float is positioned at wave trough position left by connecting rod, in this process, piston is to left movement, also drive the gas flow in pressure chamber, flow direction is contrary with a upper process, and right side breather check valve is opened and air inlet, left side outgassing nonreturn valve is opened and is given vent to anger simultaneously, and gas flow into main air flow passage and drives gas-turbine work to generate electricity.So piston enters into a reciprocating circulation along with the effect of wave, and the gas in pressure chamber also back and forth flows, and gas ceaselessly flows through gas-turbine, and then drive gas-turbine to rotate to send electric power.When wave amplitude is larger, the brake baffle installed of piston both sides can the motion amplitude of effective control piston, in order to avoid damage machinery.
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 utilizing many float types wave energy apparatus of gas-turbine of multiple float, can adapt to the incoming wave of all directions; Its electricity generating principle have employed the mode of gas-powered gas-turbine, and form is simple, stabilised efficiency; Air pressure generating apparatus is installed on apparatus main body inside, and Security is high; Device is overall, and form is simple, is convenient to manufacture and install.
