Description

A kind of floatation type has the piezoelectricity Wave energy converting device of slide link mechanism
Technical field
The invention belongs to the piezoelectricity that renewable energy power generation field more particularly to a kind of floatation type have slide link mechanism Wave energy converting device.
Background technique
Wave energy is one of most important energy in a kind of specific form and ocean energy of ocean energy, its exploitation and It is very important using to alleviating energy crisis and reducing environmental pollution.Surging ocean wave motion generates huge, eternal With environmental protection energy, if the wave energy of the kinetic energy of wave and other waters surface can be fully utilized, before world energy sources Scape can be quite wide and bright.
Seawater is a kind of fluid as composed by countless seawater particles.Under external force, seawater particle is in its equalization point Cycle movement is nearby made in position, and which forms waves.Wave is the big rule soul-stirring except the another kind of tide off-lying sea water Mould macroscopic motion.Wind more disease, wave is higher.Billow can be waved in the wind million tons wheel therewith when huge.Wind is to cause water level fluctuation Main extraneous factor.When wind skims over sea, seawater surface is produced because of the effect of frictional force and atmospheric pressure by air Vividly swing.Wind speed is the principal element for determining wave size.Under normal circumstances, when wind-force reaches 10 grades or more, the height of wave Up to 12m, it is equivalent to the height of four floors, it is usually high to 15m or more that What is more.Marine common six force 7 wind, what it was started Wave also has 3m to 6m high enough.What seawater mentioned above was made of particle, wind blow or the movement of tide can make sea Water particle RELATIVE SEA LEVEL is subjected to displacement phenomenon, so that wave be made to have potential energy, and the movement of seawater particle, and wave can be made to have There is kinetic energy.Therefore, actually wave energy be kinetic energy and potential energy possessed by ocean surface summation.The energy of wave and wave height Square, the width of the period of motion of wave and wave slope it is directly proportional.In addition, the size of wave energy also with wind speed, wind direction, continuous The factors such as time, the flow velocity of blowing are related.For example, the billow that typhoon generates, power density is up to every meter of wave slope number Megawatt.
Wave-energy power generation can be divided into energy collecting system and energy conversion system two parts.The effect of acquisition system is capture Wave energy.Its principal mode has: oscillaton water column type, oscillating float type, pendulum-type, canard, raft formula, contraction ramp-type, clamshell etc..It mentions The technology of high wave energy capture amount has: by wave energy diffraction or the poly- wave technology of refraction, being resonated by system and wave used Poly- wave technology of property etc..The effect of converting system is the mechanical or electrical energy for the wave energy of capture being converted to certain particular form. It is made of following major part: air vane, low head water turbine, hydraulic system, mechanical system and generator etc.. In addition, the methods of controllable blade, variable damping, rectification, level pressure can be used to improve transformation efficiency.By the Land use systems of wave energy, Wave-energy power generation can be roughly divided into the vertical movement using wave energy, the horizontal movement using wave energy, using wave hydraulic pressure, The forms such as the movement using wave water particle.Oscillaton water column type, pendulum-type can be divided by the structure type of the device of wave energy and gathered Three kinds of devices of waves.The oscillation and oscillating motion, utilization generated under the wave action using object can be divided into again by basic principle In the way of the variation of wave pressure, three kinds of water potential energy generated when wave bank climbs, and these three modes namely we Usually signified pneumatic type, hydrodynamic and water storage type.
Fixed wave energy generating set is either built in inshore or off-lying sea bank, all waterborne in the presence of needing to build Support building, it is not only at high cost, build difficulty it is big, moreover, flexibility is poor, encounter special circumstances, inconvenient protective device is expensive Arduously.Therefore, domestic and international primary study floating-type wave energy power generator mostly.And at present for, oscillating floater technology has Have the shortcomings that reliability is not high, some mechanical structure too complex.
Application No. is 201510505164.4 patents, disclose a kind of Wave energy converting device, comprising: the drift of at least two sections Wave energy on bubbling through the water column acquires floating body, and the prisoner's energy wobble plate being set between two adjacent sections wave energy acquisition floating body is set respectively It is placed in the hydraulic dress between two adjacent sections wave energy acquisition floating body between prisoner's energy wobble plate and two adjacent sections wave energy acquisition floating body It sets and one end is connected on one of wave energy acquisition floating body, the other end is anchored in the mooring gear of sea bed;Two adjacent sections It is by pitching axisymmetry hinged that wave energy acquires floating body, and can rotate each other around pitching rotary shaft;Capture energy One end of wobble plate be articulated with two adjacent sections wave energy acquisition floating body same pitching rotary shaft on, the other end extend to the water surface with Under, and can be around pitching rotary shaft relative to the acquisition floating body rotation of two adjacent sections wave energy.But the invention mobility is poor, limit Use environment is made.
