Below, the operation of the utility model first embodiment is described with reference to Fig. 1.In wind field, when wind-force reaches intended level, the gentle breeze of 3 meters of per seconds for example, wind wheel 1 begins to rotate.Wind wheel 1 rotates the torque that produces (power etc.) in other words and passes to unidirectional transmission 2, and first semiaxis, 31, the first semiaxis 31 that pass to differential driver 3 of the output 22 by unidirectional transmission 2 drive the first integrally formed with it angular wheel 32 and rotate.In the time of in wind-force is in scope of design, the speed-limiting device 4 between differential driver 3 and generator 5 is not worked, and promptly second semiaxis 33 and generator power shaft 51 can freely rotate.At this moment, two angular wheels act on the torque that torque on the planetary gear 35 and weight 61 produce on housing 37 in a basic balance, and weight 61 keeps motionless, (can realize by conventional design, for outstanding the utility model theme, no longer provide labor here.) housing 37 of differential driver 3 do not rotate, therefore, the unjust then just rotation of planetary gear 35.In this case, differential driver 3 has become two drive systems that angular wheel constituted that mesh by the planetary gear 35 mainly as idle pulley, and wherein, first angular wheel 32 is inputs, and second angular wheel 34 is outputs.So, generator 5 can the wind-force effect in scope of design under, produce electric energy reposefully.
When occurring exceeding the strong wind of scope of design, the trend of high speed rotating appears in the generator power shaft 51 or second semiaxis 33, at this moment, speed-limiting device 4 work between generator 5 and the differential driver 3 also produce braking force, cause the torque that acts on the planetary gear to increase, greater than the required torque that promotes weight 61, so, planetary gear 35 revolves round the sun, weight 61 is raised, the torque part that differential driver 3 is accepted passes to generator 5 by second angular wheel 34 and second semiaxis 33, makes generator 5 continue to keep normal even running; Another part, just redundance is passed to housing 37 and is used for promoting weight 61, thereby unnecessary wind energy changes potential energy into, be i.e. energy storage.
When not having wind, 32 pairs of planetary gears 35 of first angular wheel no longer act on torque, so under the torque that weight gravity is produced, the housing 37 of differential driver 3 rotates.Because the reverse power transmission of unidirectional transmission 2 is by locking or can not reverse, so, the torque that is become by the weight potential energy converting and energy is that the 3rd working end and planetary gear 35 pass to i.e. second semiaxis 33 in second working end through the housing in the differential driver 3 37, and second semiaxis 33 is rotated further along original rotation direction.Therefore,, utilize the weight potential energy that stores under the strong wind situation, still can make generator 5 continue generating, thereby reduced the intermittence of electric power output even do not having under the situation of wind.
According to the utility model, differential driver 3 and energy storage device 6 combine, utilize energy storage device 6 when wind-force is excessive, to store wind energy and too small or give differential driver 3 intakes when not having wind at wind-force, wind-force to wind wheel 1 input plays the effect in " peak clipping Pinggu ", thereby the power that export second working end of having stablized differential driver 3 makes generator can continue to move reposefully.And, to compare with existing wind power plant, the utility model is simple in structure, and cost reduces.Further,, can save the electronics, the mechanical part that are used for the complexity of speed governing in the existing wind power plant, further reduce cost, simplify the structure, increase the reliability of equipment operation according to the utility model.If wind power plant of the present utility model is formed generating set, just can provide stable power source for electrical network.
Below, with reference to Fig. 3 and Fig. 4 wind power plant according to the utility model second embodiment is described.Fig. 3 is the principle schematic according to the wind power plant of the utility model second embodiment.Fig. 4 is the schematic cross sectional views of differential driver among Fig. 3.Except differential driver 3 ', the utility model second embodiment and first embodiment are basic identical on mechanism and effect.Here only to the differential driver 3 different ' be described with first embodiment.
As shown in Figure 3 and Figure 4, the differential driver 3 of present embodiment ' comprising: link to each other with the output 22 of unidirectional transmission 2, as differential driver 3 ' first working end first semiaxis 31 '; First angular wheel 32 '; Link to each other with the power shaft 51 of generator 5, as differential driver 3 ' second semiaxis 33 of second working end; Second angular wheel 34 integrally formed with second semiaxis 33; First angular wheel 32 ' and second angular wheel 34 between and a plurality of planetary gears 35 of being meshed simultaneously with these two angular wheels; Support rotationally the pinion frame 36 of these planetary gears 35 ', pinion frame 36 ' with first semiaxis 31 ' integrally formed, so can drive planetary gear 35 revolution during first semiaxis 31 ' rotation; Surround the housing 37 of above-mentioned parts ', housing 37 ' with first angular wheel 32 ' integrally formed, can be with first angular wheel 32 ' rotate integratedly.

When wind-force exceeds scope of design, through first semiaxis 31 ', pinion frame 36 ' and planetary gear 35 act on first angular wheel 32 ' on torque increase, greater than weight 61 by housing 37 ' first angular wheel 32 ' on the torque that produces, so, first angular wheel 32 ' rotation, drive housing 37 ' lifting weight, thereby unnecessary wind energy is converted to the potential energy of weight, i.e. energy storage.In this simultaneously, second angular wheel 34 still held stationary rotates, and makes generator 5 still produce electric energy reposefully the wind drive in being designed scope.
When not having wind, the effect of 35 pairs first angular wheels 32 of planetary gear ' no longer has torque, then under the torque that weight gravity is produced, differential driver 3 ' housing 37 ' rotation, drive first angular wheel 32 ' rotation.Because the reverse power transmission of unidirectional transmission 2 is by locking or can not reverse, so, planetary gear 35 can only rotation, differential driver 3 ' become is by two drive systems that angular wheel constituted mainly as planetary gear 35 engagements of idle pulley, thereby first angular wheel 32 ' driving under, second angular wheel 34 and second semiaxis 33 are rotated further along original rotation direction.Therefore, do not having under the situation of wind, utilizing the weight potential energy that stores, generator 5 continues generating.
