Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
Shown in accompanying drawing 1, a kind of ocean current energy generator, it comprises generator 8, transmission device 9 and energy by ocean current collecting device 10, and energy by ocean current collecting device 10 links to each other with transmission device 9, and transmission device 9 links to each other with generator 8; Said energy by ocean current collecting device 10 comprises two gear shafts 4 and a driving belt 3; Two gear shafts 4 connect through driving belt 3, the internal surface of driving belt 3 be provided with gear shaft 4 on gear 2 tooth of interlock mutually, gear shaft 4 is connected through bearing with support 7 on being fixed on base 6, at least one rooted tooth wheel shaft 4 links to each other with transmission device 9; A plurality of being used for when ocean current impacts towards the open baffle parts of current direction is installed on the outer surface of said driving belt 3.
Further combining Fig. 2 and the said baffle parts of Fig. 3 is blade 1, and a plurality of blades 1 are hinged with driving belt 3, also is provided with between each blade 1 and the driving belt 3 to be used to prevent that blade 1 angle of swing from surpassing the folding connected body 5 of 90 degree.Said connected body 5 is the folding fan structure, and the upper edge of connected body 5 and blade 1 are fixing, and lower edge and driving belt 3 are fixing.Also be provided with the sensor 11 of the rotating shaft rotational velocity that is used to detect generator 8 on the said generator 8; Sensor 11 is electrically connected with speed reducer 12; The rotating shaft of arrestment mechanism on the speed reducer 12 and generator 8 matches, and described matching is meant the rotating shaft both sides of the deceleration pincers separation generator 8 on the arrestment mechanism, when needs slow down; The pincers that slow down begin to hold tightly to rotating shaft, to fall the rotating speed of end rotating shaft.Said driving belt 3 is the metal driving belt, and this kind transmission has ripe commercially available prod.
The utility model in the specific implementation; Related generator 8 is existing technology with transmission device 9; Generator 8 can also be set on the offshore platform 14 on the sea, like this longer service life of generator 8 through the guiding of transmission device 9; Transmission device 9 can be mechanisms such as belt, transmission shaft, and these all are routine techniques detailed description no longer here.The said sensor 11 that is used to detect generator 8 rotating shaft rotational velocity, promptly angle transducer can also be installed in Check point on gear shaft 4 or the transmission device 9 during practical implementation.Connected body 5 can adopt intensity high, the synthetic fiber that corrosion resistance is strong.The arrangement of blade 1 can set up on their own according to field condition in the specific implementation, generally can be by arranging at a distance from the length of a blade between each blade 1, and also freely-increased/decreased.The opening angle maximum of blade 1 can be arranged to 90 degree, but can be arranged on during practical implementation about 60 degree, because the fluid resistance from vacuum side of blade can increase under the too big situation of angle.
The working principle of the utility model is in conjunction with accompanying drawing 1, when ocean current flows from left to right; The blade 1 of energy by ocean current collecting device 10 upper half part is because its firm direction of coming towards ocean current; Under the percussion of ocean current, can open up into the angle that pre-sets, and stream can collecting device the blade 1 of 10 lower half portions because back to current direction, can closure under the effect of surge pressure; The surge pressure effect meeting that receives ocean current on the blade 1 of energy by ocean current collecting device 10 upper half part is at this moment advanced to the right; Thereby clockwise rotate through gear structure driven gear axle 4, the rotating shaft that the logical again transmission device 9 of gear shaft 4 drives generator 8 is rotated, and generator begins generating.When current direction flows to a left side from the right side; The blade 1 of energy by ocean current collecting device 10 lower half portions is because its firm direction of coming towards ocean current; Under the percussion of ocean current, can open up into the angle that pre-sets, and stream can collecting device the blade 1 of 10 upper half part because back to current direction, can closure under the effect of surge pressure; The surge pressure effect meeting that receives ocean current on the blade 1 of energy by ocean current collecting device 10 lower half portions is at this moment advanced left; Thereby clockwise rotate through gear structure driven gear axle 4, gear shaft 4 drives the rotating shaft rotation of generator 8 again through transmission device 9, and generator generates electricity.
Need to prove that the utility model has more than is limited to above mode of execution; It can also have multiple variation, and if for example said baffle parts are not necessarily hinged blade; It can also be the bucket-shaped structure made from soft fiber material; One side of bucket-shaped structure is fixed on the driving belt 3, and another side can folding under the effect of ocean current, maximum folding angle is arranged on 90 degree gets final product.Simultaneously the width of driving belt 3 also can be adjusted according to actual conditions, can widen, and blade 1 can one group be arranged side by side two like this, the perhaps front and back blade arrangement that can misplace.These change the conspicuous variation that all is based under the utility model design, all within the protection domain of the utility model.
