Abstract
A float-type wave energy generator adopts the structure that a plurality of floats with certain dead weights are connected with ends of respective oscillating bars of the floats; and the other ends of the oscillating bars are connected with dual-ratchet mechanisms in a shaft sleeve manner. The oscillating bars are connected with fixed shafts in a shaft sleeve manner. The oscillating bars can rotate together with the fixed shafts. The respective dual-ratchet mechanisms drive the same ratchet main shaft to rotate directionally, and then are speeded up by a speed changing box to drive an electric generator to generate electricity. Each dual-ratchet mechanism comprises two L-shaped pawl racks, a spring and the ratchet main shaft, and is characterized in that one end of each of the two pawl racks is connected with one end of a corresponding oscillating bar in a shaft sleeve manner; and the other ends of the two pawl racks are connected by the spring; the ratchet directions of the two pawl racks are opposite; and the two pawl racks drive the ratchet main shaft to rotate directionally in a ratchet-pawl meshed manner. The overall case is higher than the sea surface, and is fixed on a seabed through piles; and the floats float on the sea surface.

Summary of the invention
In order to improve the efficient of wave-energy power generation, the utility model adopts all-in-onecase to be fixed in the seabed by pile, cabinet is higher than the sea, a plurality of floating drums with certain deadweight, each floating drum is fixed on fork one end separately, the other end of fork is connected in the axle sleeve mode movingly with its pair ratchet mechanism, each fork is connected with stationary axle in the axle sleeve mode, the common directed rotation of the same ratchet main shaft back that drives of each two ratchet drives generator for electricity generation. many floating drums two ratchet mechanisms by separately, drive same ratchet main shaft jointly, improved stability and the efficient of generator.
The technological scheme that its technical problem that solves the utility model adopts is; Floating drum with certain deadweight is fixed on an end of fork, and the other end of fork is connected with two ratchet mechanisms movingly in the axle sleeve mode.Between fork again by the axle sleeve mode be fixed on cabinet on stationary axle to be connected movingly, make fork to rotate with stationary axle.In order to improve generating efficiency and stability, the utility model has adopted many floating drums and separately two ratchet mechanisms thereof to drive the scheme of same ratchet main shaft, the driving pawl main shaft is with the slow-speed of revolution, the directed rotation of the mode of high pulling torque, in order to cooperate the requirement of generator, after the gearbox raising speed, drive generator for electricity generation.All-in-onecase is installed and is higher than the sea, and is fixed in the seabed by pile.Cabinet not with contact with sea water, floating drum floats on the sea.
Of the present utility model pair of ratchet mechanism consists of; By two L shaped ratchet tooth bars, spring and ratchet main shaft are formed.One end of two L shaped ratchet tooth bars is connected in the axle sleeve mode movingly with an end of fork, namely can rotate mutually around axle, and the other end of two ratchet tooth bars connects with spring.The ratchet direction of two ratchet tooth bars is opposite.Between two ratchet tooth bars, the ratchet main shaft is arranged, and drive in the mode of click engagement.Like this, no matter how two ratchet tooth bars move, but all the driving pawl main shaft rotates according to a direction.The two ends of ratchet main shaft are connected with support with bearing, and it can be rotated.Support, gearbox, generator is fixed on the cabinet.
The beneficial effects of the utility model are to utilize efficient and the stability height of wave-energy power generation, and simple and reliable for structure, cost is low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the sectional drawing of one of them floating drum of the utility model and two ratchet mechanisms.
Fig. 2 is two L shaped ratchet tooth bars.
Fig. 3 is fork and floating drum.
Fig. 4 is plan view of the present utility model.
In the drawings, 1 is floating drum, and 2 is fork, and 3 is two L shaped ratchet tooth bars, and 4 is the ratchet main shaft, and 5 is spring, and 7 is fixedly shaft support of ratchet main shaft and fork, and 8 is the fork stationary axle, and 9 is gearbox, and 10 is generator.
Embodiment
In Fig. 1, floating drum 1 is fixed in an end of fork 2, and the other end of fork 2 is with mode and two L shaped ratchet tooth bar 3A of axle sleeve, and 3B connects movingly, and it can be rotated mutually.2 of forks, a fixed hole is arranged, by the mode of axle sleeve, be connected movingly with stationary axle 8, fork 2 can be rotated around stationary axle 8.Stationary axle 8 is fixed on the support 7.The two ends of ratchet main shaft 4 cooperate with support 7 with bearing, support 7, and gearbox 9, generator 10 is fixed on the cabinet.Cabinet is fixed on the seabed by pile.
Two ratchet mechanisms consist of: by two L shaped ratchet tooth bar 3A, and 3B, spring 5 and ratchet main shaft 4 are formed.Two ratchet tooth bar 3A, the end of 3B is connected in the axle sleeve mode movingly with an end of fork 2, namely can rotate mutually, two ratchet tooth bar 3A, the other end of 3B connects with spring 5, two ratchet tooth bar 3A, the ratchet direction of 3B is opposite.At two ratchet tooth bar 3A, between 3B, ratchet main shaft 4 is arranged, and drive in the mode of click engagement.
The working principle of two ratchet mechanisms now is described with Fig. 1: when floating drum 1 floats, by fork 2 the ratchet tooth bar is moved downward, at this moment, ratchet tooth bar 3A driving pawl main shaft 4 is rotated counterclockwise, and ratchet tooth bar 3B skids.When floating drum 1 sinks, by fork 2 the ratchet tooth bar is moved upward, at this moment, and the rotation of ratchet tooth bar 3B driving pawl spindle axis counterclockwise, ratchet tooth bar 3A skids.So no matter how the ratchet tooth bar moves, and all the driving pawl spindle axis counterclockwise is rotated.
Because the utility model is made up of many floating drums and two ratchet mechanism, the existing driving relationship that two ratchet mechanisms and the ratchet main shaft 4 of many floating drums are described with Fig. 4.In Fig. 4, if some floating drums remain static, at this moment, ratchet main shaft 4 is being rotated counterclockwise, the floating drum that remains static and two ratchet mechanism 3A thereof, and 3B also remains static, at this moment, for the ratchet main shaft of rotation, 3A and 3B skid, for the not influence of rotation of ratchet main shaft.
The effect of fork 2 now is described with Fig. 3; One end of fork 2 is connected with floating drum 1, and the other end is connected in the axle sleeve mode movingly with two ratchet mechanisms.2 of forks a fixed hole is arranged, be connected movingly with stationary axle 8, fork 2 can be rotated by stationary axle 8, the fork 2 actual effects of playing lever, stationary axle is fulcrum, and fulcrum is power arm to floating drum 1, and fulcrum is resistance arm to the tie point of ratchet tooth bar.According to lever principle, when the length of power arm during greater than the length of resistance arm, moving up and down of floating drum can increase the rotation torque of ratchet main shaft.
