[0001] The present application relates to the field of wind power generation devices, and more particularly, to an emergency power protection device for a wind power generation device. Background Art

[0002] Wind energy is the most mature and large-scale developable renewable clean energy in current technology. The development of wind energy provides a basis for the harmonious development of humans and nature. Since wind turbines work in a natural environment, they will inevitably be affected by natural disasters.

[0003] For example, the Chinese patent publication number is CN112145351A, and the technical solution disclosed in this patent document is as follows: A wind power generation equipment protection device based on the Internet of Things, including a power generation chamber, a transmission shaft is inserted into the right wall of the power generation chamber, a driving gear is sleeved on the outer wall of the right side of the transmission shaft, a transmission gear is meshed with the outer wall of the driving gear, a generator is fixedly connected to the left side of the transmission gear, a reduction gear is sleeved on the outer wall of the left side of the transmission shaft, a reduction rod is movably connected to the inner wall of the reduction gear, and a rack is meshed with the outer wall of the reduction gear. This wind power generation equipment protection device based on the Internet of Things ejects the internal rack through an electromagnetic sleeve, the rack drives the reduction gear to rotate, and the reduction gear makes the reduction rod drive the reduction piece to fit with the transmission shaft through the guide groove opened on the front to decelerate the transmission shaft, avoiding damage to the generator due to too high a rotation speed of the transmission shaft and extending the service life of the wind power generation equipment.

[0004] Regarding the existing technology, there are the following problems: The above device drives the plug to move to the right to engage with the socket through a slider. When the slider no longer receives the pulling force of the counterweight ball, the return spring extends to drive the slider to move to the right, and the plug is disengaged from the socket. After the plug engages with the socket, it is very difficult to pull out the longitudinally inserted plug through the laterally applied force by the return spring. Even if it is pulled out, it will cause a certain amount of friction. In addition, if the wind speed changes too fast, the plug and the socket will engage and disengage frequently, which is not only difficult to achieve timeliness but also prone to short circuits.

A rotating disk 610 is rotatably connected inside the receiving box 52, a chute 611 is opened on the side surface of the rotating disk 610, a roller 612 is slidably connected inside the chute 611, a deceleration splint 620 is arranged outside the transmission shaft A51, and a hydraulic component for pushing the deceleration splint 620 is arranged on the side surface of the receiving box 52. The hydraulic component includes a columnar hydraulic bin 613, the columnar hydraulic bin 613 is fixedly connected to the outer wall of the receiving box 52, a connecting pipe 616 is fixedly connected to the upper end of the columnar hydraulic bin 613, a hydraulic rod A614 is slidably connected inside the columnar hydraulic bin 613, an arc-shaped plate 615 is fixedly connected to the bottom of the hydraulic rod A614, the other end of the connecting pipe 616 is fixedly connected to an annular plate 618, a ring-shaped hydraulic bin 617 is fixedly connected to the outer wall of the power generation bin 3, the annular plate 618 is rotatably connected to the outer wall of the ring-shaped hydraulic bin 617 and the connecting pipe 616 is communicated with the ring-shaped hydraulic bin 617, a hydraulic rod B619 is slidably connected inside the ring-shaped hydraulic bin 617, and the other end of the hydraulic rod B619 is fixedly connected to the deceleration splint 620. The transmission shaft A51 is fixedly connected to the outer wall of the power generation bin 3 and is fixedly connected to the generator inside the power generation bin 3, the receiving box 52 is fixedly connected between the transmission shaft A51 and the transmission shaft B53, the fan blade 54 is fixedly connected to the other end of the transmission shaft B53, the connecting ring 67 is slidably connected to the outer wall of the transmission shaft B53, and a spring 621 is fixedly connected between the fixing ring 61 and the rotating ring 65. A water collecting component 7 is assembled on the outer wall of the support column 2, and an adjusting component 8 is assembled on the outer wall of the power generation bin 3.

[0026] During use, when encountering strong wind weather, under the action of the fan blades 54, the drive shaft A 51, the accommodation box 52, and the drive shaft B 53 will increase their rotational speeds. Consequently, the fixing ring 61 fixedly sleeved outside the drive shaft B 53 will also accelerate its rotational speed. Then, the connecting rod A 62 hinged thereto will drive the centrifugal ball 63 to rotate accordingly. Due to the increased rotational speed, the centrifugal ball 63 will drive the connecting rod A 62 to open outward under the action of centrifugal force. Subsequently, it will drive the rotating ring 65 to squeeze the spring 621 and move closer to the fixing ring 61 through the connecting rod B 64. Then, the rotating ring 65 will drive the connecting ring 67 to move. As a result, the connecting rods A 68 on both sides of the connecting ring 67 will also move closer to the fixing ring 61, and then the baffle 69 can be driven to slide outward from the inside of the air intake pipe 66. Since the air intake pipe 66 rotates with the accommodation box 52, when the baffle 69 releases the blockage on one side of the air intake pipe 66, air will enter the inside of the accommodation box 52, and then drive the rotating disk 610 to rotate. Subsequently, the roller 612 sliding in the chute 611 on the side surface of the rotating disk 610 will slide outward under the action of centrifugal force. Because during the rotation of the rotating disk 610, the roller 612 will push the arc-shaped plate 615 closer to the inner wall of the accommodation box 52. Then, the hydraulic rod A 614 at the upper end of the arc-shaped plate 615 will slide into the inside of the columnar hydraulic chamber 613. Then, the connecting pipe 616 will drive the annular plate 618 to rotate while transporting the hydraulic oil inside the columnar hydraulic chamber 613 to the inside of the annular hydraulic chamber 617. Then, the hydraulic rod B 619 slidingly connected inside the annular hydraulic chamber 617 will slide outward, thereby driving the deceleration clamping plate 620 to move towards the drive shaft A 51 until it contacts the drive shaft A 51, and then the deceleration of the drive shaft A 51 can be achieved. Subsequently, the drive shaft B 53, the accommodation box 52, and the fan blades 54 will all decelerate accordingly, avoiding damage to the generator due to excessive rotational speed of the drive shaft and extending the service life of the wind power generation equipment.

[0027] Example 2, please refer to Figures 1 - 7, on the basis of Embodiment 1, the water collection assembly 7 includes a moving ring 71 which is slidably connected to the outer wall of the transmission shaft B53.

A connecting cover 712 is fixedly connected to the upper end of the L-shaped plate 711, and a dredging rod 713 is fixedly connected to the outer wall of the connecting cover 712.

A limiting rod B715 is fixedly connected to the outer wall of the support column 2, and the connecting rod B72 is slidably connected to the outer wall of the limiting rod B715. The arrangement of the limiting rod B715 can limit the moving range of the connecting rod B72 so that it can only move horizontally.

[0028] During use, when it rains, the filter cover 77 filters the rainwater. Then the filtered rainwater will enter the inside of the collecting hopper 75 and be collected. Finally, the rainwater will be input into the cooling water tank inside the support column 2 through the delivery pipe at the bottom of the collecting hopper 75. When the connecting ring 67 moves towards the fixed ring 61, it will drive the moving ring 71 to move synchronously, and then drive the toothed plate 73 to move through the connecting rod B72. When the toothed plate 73 moves, the meshing gear 78 will rotate accordingly. Then the connecting rod C79 at the upper end of the gear 78 will also rotate accordingly. The connecting rod C79 will drive the scraping plate 710 to clean the surface of the filter cover 77. When the connecting rod C79 moves to the lower end of the L-shaped plate 711, it will lift the L-shaped plate 711 upwards, so that the L-shaped plate 711 slides on the outer wall of the limiting rod A716. Then the connecting cover 712 fixedly connected to the upper end of the L-shaped plate 711 will move upwards, and then the dredging rod 713 at the upper end of the connecting cover 712 will move upwards to filter the filter holes of the filter cover 77.

Thus, the sliding shaft 86 slidably connected inside it can move downward during the movement, so as to drive the mounting shaft 83 to rotate through the connecting block 85. The sliding shaft 86 is slidably connected inside the guiding groove 89.

[0030] During use, when the toothed plate 73 moves, it indicates a strong wind weather. When the toothed plate 73 moves, it will drive the connecting rod D87 to move. Further, the connecting rod D87 will drive the moving plate 88 to move. Further, the sliding shaft 86 will slide along the guiding groove 89, so as to drive the mounting shaft 83 to rotate through the connecting block 85, and thus the lightning rod 84 can be driven to tilt at a certain angle.
