Description

Wave generator

Technical field: the present invention relates to a kind of simple in structure, wave-type electric generator that the wave energy utilization ratio is high, because of it can efficiently utilize kinetic energy of wave, can utilize tidal energy again, so be called Wave generator.

Background technique: containing huge energy in ten thousand hectares of great waves of immense ocean.In the energy day by day deficient today, can utilize to scientific and efficient this part reproducible clean energy resource to become the important topic of coastal state's using energy source, but the research of relevant this respect never have substantive breakthroughs.Existing wave-activated power generation technology can be divided into two kinds: a kind of is to adopt to be similar to the generate electricity wheeled wave energy converyer of widely used water turbine of river, it utilizes the horizontal impact power of tide and ocean current to drive generator for electricity generation, this device can only be installed on the bank, and metal rotating machinery long period of soaking is in the seawater of high salinity, highly corrosive, and its working life is very short; Another kind is to adopt the float (float of floatability mechanical part common name in the past) of various proterties such as the buoyancy tank that rises and falls with ripple or keg float by the generating of rack drives power facility, but, make the tooth bar can't transmission because the non-directional horizontal impact of tide and ocean current can cause the rotation of float occurred level.And to prevent horizontally rotating of float, and no matter be the quantity that increases parallel slideway or guide rail, still adopt the square column transmission, all can increase surface friction drag greatly, reduce generating efficiency, make its forfeiture Economy, be difficult to promote the use of.

Summary of the invention: the present invention just provides and a kind ofly need not to prevent float to horizontally rotate thereby wave energy utilization ratio height, and is simple in structure, good economy performance, and can adapt to the Wave generator of any marine site (the floating type device can be adopted in the deep-sea).This electricity generating device is made up of three mechanisms: one, support fixation mechanism: be made up of a body fixing frame (bar) and the moving direction regulation arm that the sliding bearing sleeve pipe is housed in order to two ends that guarantee the vertical up-or-down movement of T type wave energy converyer mounted thereto; Two, energy delivery mechanisms: by be connected together driving cog post (it is more accurate to be called " ring tooth drive link ") with same axis and form of T type wave energy converyer and being attached thereto with the generator driving cog axle of its engagement; Three, Conversion of energy mechanism (power facility just): constitute by a rotor generator.

One of critical component of the present invention is a T type wave energy converyer.Its structure is to constitute an inverted T shape structure by a horizontal floating block of the rigid body that can partly bubble through the water column (can certainly be the float of kickboard, buoyancy tank, keg float and other any proterties) with a vertical driving pillar stand (cylinder axis passes the floating block focus point) that is vertically fixed on its top center position, so claim T type wave energy converyer.Though its structure is very simple, can efficiently, absolutely obtain and transmit the energy of wave, its institute's capacitation with and its wave institute capacitation of instant water displacement equal volume equate fully.That is to say that part just is equivalent to a rigid body wave with volume in the water of this converyer, difference is that the wave of fluid can't install drive link.The vertical up-or-down movement that rises and fall on the waves of this wave energy converyer passes to power facility with kinetic energy of wave and changes into electric energy.Simultaneously, it serves as the axle rotation with vertical driving pillar stand that tide causes floating block with the nondirectional horizontal impact of ocean current, make this horizontal impact power not only can not block the up-and-down movement of T type wave energy converyer, can also dissolve and share intrinsic surface friction drag between vertical driving pillar stand and the sliding bearing sleeve pipe on the contrary, make up-and-down movement more smooth and easy.It serves to show that thus this wave energy converyer is that current wave energy transmission efficiency in the world is the highest.

Two of critical component of the present invention is driving cog posts.It is a kind of cylindric ring tooth drive link that is formed by the bigger materials processing of rigidity, the closed hoop tooth that its tooth is equal and opposite in direction, be parallel to each other, and each monodentate circular planes is perpendicular to the driving cog mast axis, and this axis is by each ring tooth circle ring center point.The driving cog post links together with the vertical driving pillar stand of T type wave energy converyer, and has common axis, and its effect is: comprehensive transmission.Just working as T type wave energy converyer serves as that axle is under the non-directional horizontal impact of tide and ocean current with vertical driving pillar stand, when rotating to any angle or orientation, be attached thereto together and the coaxial thereupon normally transmission of driving cog post with closed hoop tooth of rotating with speed.

Description of drawings: accompanying drawing is a Wave generator unit schematic representation

Among the figure: 1, consumer networks; 2, the utility pole body fixed support of holding concurrently; 3, moving direction regulation arm (on); 4, the sliding bearing sleeve pipe (on); 5, steel clamp; 6, generator; 7, driving cog axle; 8, driving cog post (having another name called ring tooth drive link); 9, moving direction regulation arm (descending); 10, sliding bearing sleeve pipe (descending); 11, the vertical driving pillar stand float feathering axis (i.e. the smooth rigid cylindrical of a section surface) of holding concurrently; 12, horizontal floating block (float).

Embodiment: this electricity generating device both can be fixed on the immobilizing foundations such as reaching the seabed, shallow sea on bank, the reef by support (bar) 2 and form the stationary power generation device; Also can by two moving direction regulation arms 3 in the fixed mechanism with 9 and clamp 5 will be directly installed on the large-scale floating debriss such as boats and ships, floating platform and form the floating type electricity generating device by T type wave energy converyer, driving cog post 8, the generator 6 that horizontal floating block 12 and vertical driving pillar stand 11 are formed.The two common characteristic is: the total displacement of rigid body floating block 12 equals two times of weight sum of T type wave energy converyer and driving cog post, could guarantee that like this T type converyer has enough buoyancy (matching when falling) and enough distances that moves upward.Different is for they: designs fix formula electricity generating device should be considered the influence of morning and evening tides, so its driving cog post (ring tooth drive link) length floating type more than or equal to the basis of two times of wave amplitudes on tidal height of lengthening, make morning and evening tides (only limit can touch the part tidewater of T type converyer) can obtain utilizing simultaneously; And design floating type electricity generating device needn't be considered the influence of morning and evening tides because of the reason of " when the river rises the boat goes up ".
