As shown in fig. 1, the present invention provides a wind power generator 10 for realizing stable power output based on a combination of rotating shafts of a turntable, comprising: a power generation base 20, windmill blades 30, self-adjusting transmission 40, and a genset 50.
The windmill blades 30 are arranged on the power generation base 20, the generator set 50 is arranged in the power generation base 20, and the windmill blades 30 are in driving connection with the generator set 50 through the self-adjusting transmission device 40. In wind power generation, the windmill blades 30 are driven by wind to rotate and transmit kinetic energy to the generator set 50 through the self-adjusting transmission 40. During this time, the self-adjusting transmission device 40 automatically adjusts the transmission ratio according to the wind intensity, so that the generator set 50 obtains a stable rotation speed, and thus a stable output power.
As shown in fig. 2, the self-adjusting transmission 40 includes: a device support 100, a shuttle assembly 200, and a torque transfer assembly 300.
Specifically, as shown in fig. 3, the shuttle assembly 200 includes: a wind sensing sail 210 (as shown in fig. 1), a moving slider 220, and a telescoping elastic 230. The movable sliding block 220 is movably arranged on the device bracket 100, the wind sensing sail 210 is arranged on the movable sliding block 220, and the telescopic elastic part 230 provides elastic force for the movable sliding block 220. The wind power perception sail 210 is used for perceiving the strength of wind power, in the process of wind power generation, the wind power perception sail 210 is pushed by the wind power and drives the moving slide block 220 to move together, and the moving distance of the wind power perception sail 210 and the moving slide block 220 can represent the strength of the wind power.
In the present embodiment, as shown in fig. 2, the device bracket 100 is provided with a sliding guide groove 110 engaged with the movable slider 220, and the movable slider 220 is slidably disposed in the sliding guide groove 110. In this way, the moving slider 220 can slide in a designated direction more stably when the wind sensing sail 210 is pushed.
Specifically, as shown in fig. 3 and 4, the torque transmission assembly 300 includes: an input shaft 310, a driving turntable 320, a driving rotary ball 330 and a driven rotary shaft 340. The input shaft 310 is drivingly connected to the windmill blades 30, and the driven rotation shaft 340 is connected to the generator set 50. The driving turntable 320 and the driven rotating shaft 340 are rotatably mounted on the device bracket 100, the transmission rotating ball 330 is arranged on the movable slider 220, the driving turntable 320 is in driving connection with the input shaft 310, and the driven rotating shaft 340 is connected with the driving turntable 320 through the transmission rotating ball 330.
In this embodiment, as shown in fig. 4, a first bevel gear 350 is disposed on the input shaft 310, a second bevel gear 360 is disposed on the driving turntable 320, and the first bevel gear 350 engages with the second bevel gear 360. Thus, the windmill blade 30 can smoothly transmit the kinetic energy to the driving turntable 320 with different axial directions through the input shaft 310.
As shown in fig. 4, 5, and 6, the kinetic energy transfer process in the wind power generation process is as follows: the windmill blades 30 drive the input shaft 310 to rotate, and the input shaft 310 drives the driving turntable 320 to rotate through the meshing of the first bevel gear 350 and the second bevel gear 360. The driving turntable 320 transmits the kinetic energy to the driven rotating shaft 340 through the transmission rotating balls 330, and finally the driven rotating shaft 340 drives the generator set 50 to realize wind power generation. During this period, in order to provide the generator set 50 with stable output power, the rotation speed of the driven rotating shaft 340 needs to be kept constant during the power generation process, and therefore, the adaptive adjusting device 40 needs to automatically adjust the transmission ratio transmitted by the torque transmission assembly 300 according to the strength of the wind.
The following explains a specific adjustment process of the adaptive adjustment device 40:
when the wind force is weak, the input shaft 310 is driven by the windmill blades 30 to rotate, and the input shaft 310 rotates slowly and has a small torque. In order to enable the driven rotating shaft 340 to transmit the proper rotating speed to the generator set 50, the rotating speed transmitted to the driven rotating shaft 340 needs to be increased through the torque transmission assembly 300, and the adaptive adjusting device 40 is in the state shown in fig. 3. At this time, the transmission rotating ball 330 is pressed on the driven rotating shaft 340 and the outer ring a of the driving turntable 320, and because the distance from the outer ring a to the rotation central axis of the driving turntable 320 is far, the linear velocity at the outer ring a is faster than the center of the driving turntable 320 in the same angular velocity state, the rotating speed of the transmission rotating ball 330 pressed on the outer ring a can obtain a larger magnification, that is, the torque transmission assembly 300 has a smaller transmission ratio, so that the driven rotating shaft 340 obtains a faster rotating speed;
when the wind force is strong, the input shaft 310 driven by the wind turbine blade 30 has a high rotation speed and a high torque, and the rotation speed transmitted to the driven shaft 340 needs to be adjusted by the torque transmission assembly 300 so that the driven shaft 340 can maintain the original rotation speed, and the adaptive control device 40 is in the state shown in fig. 7. At this time, the strong wind force pushes the wind sensing sail 210 and the moving slider 220 to slide, the driving rotating ball 330 moves from the outer ring a to the inner ring B under the driving of the moving slider 220, because the distance from the inner ring B to the rotation central axis of the driving turntable 320 is shorter than that from the outer ring a, the linear velocity at the inner ring B is smaller than that at the outer ring a, the rotating speed of the driving rotating ball 330 pressed at the inner ring B obtains a smaller magnification factor, that is, the torque transmission assembly 300 has a larger transmission ratio, so that the driven rotating shaft 340 obtains a suitable rotating speed.
It should be noted that, because the strength of the wind force is constantly changing, the matching state of the components in the adaptive adjusting device 40 is also constantly changing, and when the wind force is gradually strengthened, the adaptive adjusting device 40 is gradually changed from the state shown in fig. 3 to the state shown in fig. 7; when the wind gradually weakens, the adaptive control device 40 changes gradually from the state shown in fig. 7 to the state shown in fig. 3. In the process of adjustment of the adaptive adjustment device 40, the transmission rotating ball 330 obtains different amplification factors, i.e., different transmission ratios, due to different pressing positions, so that the rotating speed transmitted to the driven rotating shaft 340 can always be kept unchanged, thereby ensuring that the rotating speed obtained by the generator set 50 is unchanged, and further keeping the output power generated by the generator set 50 stable.
It is emphasized that in order to make the adaptive control device 40 automatically adjust according to the intensity of the wind, a designer adds the elastic member 230. Preferably, the elastic member 230 has a spring structure. Thus, the elastic member 230 can exert the following advantageous effects: firstly, when the wind force is gradually strengthened, the movable sliding block 220 compresses the flexible elastic member 230, and due to the deformation characteristic of the flexible elastic member 230, the compression amount of the flexible elastic member 230 is equal to the moving distance of the movable sliding block 220 and is linearly related to the strength of the wind force, so that the one-to-one correspondence relationship between the pressing position of the transmission rotary ball 330 and the strength of the wind force is ensured, and the automatic adjustment is realized; secondly, when the wind is gradually weakened, the elastic member 230 provides a restoring elastic force to the moving slider 220, thereby providing a power for restoring the self-adjusting actuator 40.
It is particularly emphasized that the adaptive control device 40 also takes into account the torque factor in the control according to the wind strength. As shown in fig. 3, when the wind is weak, the transmission rolling ball 330 is pressed on the outer ring a of the driving turntable 320, and since the distance from the outer ring a to the rotation central axis of the driving turntable 320 is relatively long, it can be known from the torque formula that the driving turntable 320 only needs a relatively small torque, similar to a labor-saving lever. Therefore, under the condition of weak wind power, the driving requirement can be met by the small wind power, and wind power generation is realized. Therefore, the wind driven generator can better utilize weak wind, and the application range of the wind driven generator is also improved to a certain extent.
In one embodiment, as shown in FIG. 4, the active dial 320 is attached to the device holder 100 by a compression spring 370. Preferably, the compression elastic member 370 is a spring structure. The following benefits can be obtained by such a design: first, the torque transfer assembly 300 parts are held more tightly in compression. During the installation and adjustment process, the problem of untight fit among the driving turntable 320, the transmission rotating ball 330 and the driven rotating shaft 340 is inevitable, and the problems can cause slippage during the transmission process and affect the transmission efficiency. The compression elastic member 370 can provide a certain elastic force for the driving turntable 320, so that the parts of the torque transmission assembly 300 are more tightly matched, and the transmission stability and the transmission efficiency are improved; secondly, during installation and maintenance, a worker can compress the compression elastic element 370 to prevent the driving turntable 320 from being pressed with the transmission rotary ball 330, thereby facilitating the installation and replacement of the driving turntable 320 and the transmission rotary ball 330.
In one embodiment, the transmission rotating beads 330 are a rubber sphere structure; the driving turntable 320 and the driven shaft 340 are both provided with anti-slip threads (not shown). Therefore, the friction coefficient of the contact surface of the driving turntable 320, the transmission rotating balls 330 and the driven rotating shaft 340 can be increased, so that the sliding is not easy to occur in the transmission process, and the transmission efficiency is improved.
In summary, the wind turbine 10 for realizing stable power output based on the combination of the turntable and the rotating shaft can be timely adjusted in the wind power generation process to realize stable power output.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
