[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Embodiment 1

[0019] Please refer to Figures 1-6 , a fixing bracket for a wind power generation device, including a base 100, a limit seat 200 is assembled on the top of the base 100, a lead screw 300 driven by a servo motor is assembled on the top of the base 100, a moving block 400 is connected to the outside of the lead screw 300 through a threaded setting, a wind turbine support 500 is assembled on the side of the moving block 400. Starting the servo motor can drive the rotation of the lead screw 300 driven by the servo motor. The moving block 400 assembled on the outside of the lead screw 300 through a thread is restricted by the limit seat 200 slidably connected to the moving block 400. Thus, the moving block 400 can move in the vertical direction of the lead screw 300. The moving block 400 then drives the wind turbine support 500 assembled on its side to move. And by changing the rotation direction of the lead screw 300, the moving block 400 can be driven to move downward or upward, thereby driving the wind turbine on the wind turbine support 500 to move downward or upward; A hydraulic chamber one 601 is fixedly connected to the outside of the lead screw 300. Inside the hydraulic chamber one 601, a slider 603 is slidably connected through the arrangement of a first elastic telescopic rod 602. An arc-shaped plate 604 is slidably connected to the side of the hydraulic chamber one 601. When the lead screw 300 rotates rapidly to drive the wind turbine on the wind turbine support 500 to move downward, the lead screw 300 simultaneously drives the hydraulic chamber one 601 fixedly connected thereto to rotate rapidly. The slider 603 inside the hydraulic chamber one 601 can, under the action of centrifugal force, stretch the first elastic telescopic rod 602 and slide inside the hydraulic chamber one 601, increasing the pressure inside the hydraulic chamber one 601 and driving the arc-shaped plate 604 slidably connected to the hydraulic chamber one 601 to move.

[0020] A hydraulic device 605 is assembled on the base 100 and the wind turbine support 500. One end of the hydraulic device 605 is slidably connected to a force-bearing rod 606. The force-bearing rod 606 is located on the side of the arc-shaped plate 604 and is in contact with the arc-shaped plate 604. The other end of the hydraulic device 605 is slidably connected to a moving rod 607. A first spring 608 is assembled on the side of the force-bearing rod 606. The end of the first spring 608 away from the force-bearing rod 606 is assembled on the inner wall of the hydraulic device 605. An outer plate 609 is fixedly connected to the side of the moving rod 607. A friction inner plate 611 is connected to the side of the outer plate 609 through the arrangement of a second elastic telescopic rod 610. While rotating, the arc-shaped plate 604 extends, thereby squeezing the force-bearing rod 606. Cooperating with the hydraulic device 605 slidably connected to the force-bearing rod 606, the pressure inside the hydraulic device 605 is increased, driving the moving rod 607 slidably connected to the hydraulic device 605 to move. The moving rod 607 drives the outer plate 609 fixedly connected thereto to move sideways, causing the outer plate 609 to drive the friction inner plate 611 to move through the second elastic telescopic rod 610. The two friction inner plates 611 move towards each other, and the rotating shaft of the wind turbine located there can be initially clamped. This prevents the fan blades and the rotating shaft of the wind turbine from causing harm to nearby workers due to shaking.

[0021] After the maintenance is completed, when the wind turbine on the wind turbine support 500 is moved to the top position, then the servo motor is deactivated, causing the lead screw 300 and the hydraulic chamber one 601 to stop rotating. The slider 603 loses the restriction of centrifugal force and is reset under the action of the first elastic telescopic rod 602. Similarly, the arc-shaped plate 604 is reset, causing the force-bearing rod 606 to lose the restriction of the arc-shaped plate 604 and be reset under the action of the first spring 608. Similarly, the friction inner plate 611 is reset, canceling the initial clamping of the rotating shaft of the wind turbine. This facilitates the subsequent use of the device. An extrusion assembly 700 for extruding the friction inner plate 611 is assembled on the wind turbine support 500. An auxiliary buffer assembly 800 for buffering the rotating shaft of the wind turbine is assembled on the side of the limit seat 200.

[0022] During use, start the servo motor, which can drive the rotation of the lead screw 300 driven by the servo motor. The moving block 400 assembled on the outside of the lead screw 300 through threads is restricted by the limiting seat 200 slidably connected to the moving block 400. As a result, the moving block 400 can move in the vertical direction of the lead screw 300. The moving block 400 then drives the wind turbine support 500 assembled on its side to move. By changing the rotation direction of the lead screw 300, the moving block 400 can be driven to move downward or upward, thereby driving the wind turbine on the wind turbine support 500 to move downward or upward. When the lead screw 300 rotates rapidly to drive the wind turbine on the wind turbine support 500 to move downward, the lead screw 300 simultaneously drives the hydraulic chamber 1 601 fixedly connected to it to rotate rapidly. The sliding block 603 in the hydraulic chamber 1 can stretch the elastic telescopic rod 1 602 under the action of centrifugal force and slide in the hydraulic chamber 1, increasing the pressure in the hydraulic chamber 1 and driving the arc-shaped plate 604 slidably connected to the hydraulic chamber 1 to move. At this time, the arc-shaped plate 604 extends while rotating, thus squeezing the stress rod 606. Cooperating with the hydraulic device 605 slidably connected to the stress rod 606, the pressure in the hydraulic device 605 is increased, driving the moving rod 607 slidably connected to the hydraulic device 605 to move. The moving rod 607 drives the outer plate 609 fixedly connected to it to move sideways, causing the outer plate 609 to drive the friction inner plate 611 to move through the elastic telescopic rod 2 610. The two friction inner plates 611 move towards each other, and the rotation shaft of the wind turbine located there can be initially clamped. After the maintenance is completed, when the wind turbine on the wind turbine support 500 is moved to the top position, then stop the servo motor, causing the lead screw 300 and the hydraulic chamber 1 601 to stop rotating. The sliding block 603 loses the restriction of centrifugal force and resets under the action of the elastic telescopic rod 1 602. Similarly, the arc-shaped plate 604 resets, causing the stress rod 606 to lose the restriction of the arc-shaped plate 604 and reset under the action of the spring 1 608. Similarly, the friction inner plate 611 resets, canceling the initial clamping of the rotation shaft of the wind turbine.

[0023] Embodiment 2

[0024] Please refer to Figures 1-7, on the basis of the first embodiment, the extrusion assembly 700 includes a second hydraulic chamber 701. One end of the second hydraulic chamber 701 is slidably connected to a transmission rod 702, and the other end of the second hydraulic chamber 701 is slidably connected to a special-shaped rod 703. A second spring 704 is assembled on the top of the transmission rod 702. One end of the second spring 704 away from the transmission rod 702 is assembled on the inner wall of the second hydraulic chamber 701. When the moving rod 607 moves a certain distance to the side, the second hydraulic chamber 701 assembled on it can be driven to move the same certain distance. When the wind turbine on the wind turbine support 500 moves to the bottom position, the transmission rod 702 slidably connected to the second hydraulic chamber 701 is restricted by the base 100. Under the action of the base 100, the transmission rod 702 slides into the second hydraulic chamber 701, increasing the pressure inside the second hydraulic chamber 701 and driving the special-shaped rod 703 slidably connected to the second hydraulic chamber 701 to move to the side.

[0025] A through hole 705 is provided on the side of the outer plate 609. A force-receiving plate one 707 is connected to the side of the friction inner plate 611 by a third spring 706. The force-receiving plate one 707 is located on the side of the special-shaped rod 703 and is in contact with the special-shaped rod 703. When the special-shaped rod 703 moves to the side, the special-shaped rod 703 immediately presses the force-receiving plate one 707, causing the force-receiving plate one 707 to apply an additional force to the friction inner plate 611 through the third spring 706. Further reducing the possibility of the wind turbine blades rotating and improving the protection effect of the device on nearby workers.

[0026] When the wind turbine on the wind turbine support 500 moves upward for resetting, the restriction of the base 100 on the transmission rod 702 gradually disappears. The transmission rod 702 loses the restriction and can be reset under the action of the second spring 704 connected to it. Similarly, the special-shaped rod 703 is reset, and the force-receiving plate one 707 can return to its initial state under the action of the third spring 706 and the elastic telescopic rod two 610. Facilitating the subsequent use of the device.

[0027] During use, based on the first embodiment, when the moving rod 607 moves a certain distance to the side, it can drive the second hydraulic chamber 701 assembled thereon to move the same distance. When the wind turbine on the wind turbine support 500 moves to the bottom position, the transmission rod 702 slidably connected to the second hydraulic chamber 701 is restricted by the base 100. Under the action of the base 100, the transmission rod 702 slides into the second hydraulic chamber 701, increasing the pressure inside the second hydraulic chamber 701 and driving the special-shaped rod 703 slidably connected to the second hydraulic chamber 701 to move to the side. The special-shaped rod 703 then squeezes the first force-receiving plate 707, causing the first force-receiving plate 707 to apply an additional force to the friction inner plate 611 through the third spring 706. When the wind turbine on the wind turbine support 500 moves upward for reset, the restriction of the base 100 on the transmission rod 702 gradually disappears. The transmission rod 702 loses the restriction and can be reset under the action of the second spring 704 connected thereto. Similarly, the special-shaped rod 703 is reset, and the first force-receiving plate 707 can return to the initial state under the action of the third spring 706 and the second elastic telescopic rod 610.

[0028] Embodiment Three

[0029] Please refer to Figures 1-8 Based on the first and second embodiments, the auxiliary buffer assembly 800 includes a third hydraulic chamber 801, which is located on the side of the hydraulic device 605 and is in a communicating state with the hydraulic device 605. A connecting rod 802 is slidably connected to the top of the third hydraulic chamber 801, and a second force-receiving plate 803 is fixedly connected to the top of the connecting rod 802. When the wind turbine on the wind turbine support 500 moves to the bottom position, the moving block 400 is also at a position close to the bottom at this time, thereby squeezing the second force-receiving plate 803, causing the second force-receiving plate 803 to drive the connecting rod 802 fixedly connected thereto to move downward. Cooperating with the third hydraulic chamber 801 slidably connected to the connecting rod 802, the pressure inside the third hydraulic chamber 801 increases.

[0030] Inside the third hydraulic chamber 801, a rotating shaft 804 is rotatably connected. On the outer side of the rotating shaft 804, a baffle 805 is fixedly connected. On the side of the baffle 805, an elastic telescopic plate 806 is assembled. When the pressure inside the third hydraulic chamber 801 increases, the liquid pressure inside the third hydraulic chamber 801 immediately presses against the baffle 805, causing the baffle 805 to rotate around the rotating shaft 804 as the axis, stretching the elastic telescopic plate 806 to a certain angle state, so that the third hydraulic chamber 801 originally closed by the baffle 805 is completely opened. At this time, the connecting rod 802 continues to move downward under the action of the moving block 400, causing the pressure inside the third hydraulic chamber 801 to continue to increase and be transmitted to the hydraulic device 605 connected to the third hydraulic chamber 801. However, the force-receiving rod 606 is restricted by the arc-shaped plate 604 and cannot move, causing the liquid pressure to move toward the side close to the moving rod 607, driving the outer plate 609 to squeeze the second elastic telescopic rod 610 and continue to apply an additional force to the friction inner plate 611. The buffering effect of the device on the rotating shaft of the wind turbine is improved.

[0031] In use, on the basis of Embodiment 1 and Embodiment 2, when the wind turbine on the wind turbine support 500 moves to the bottom position, the moving block 400 is also at a position close to the bottom at this time, thus squeezing the second force-receiving plate 803, causing the second force-receiving plate 803 to drive the connecting rod 802 fixedly connected thereto to move downward, cooperating with the third hydraulic chamber 801 slidably connected to the connecting rod 802, causing the pressure inside the third hydraulic chamber 801 to increase. The liquid pressure inside the third hydraulic chamber 801 immediately presses against the baffle 805, causing the baffle 805 to rotate around the rotating shaft 804 as the axis, stretching the elastic telescopic plate 806 to a certain angle state, so that the third hydraulic chamber 801 originally closed by the baffle 805 is completely opened. At this time, the connecting rod 802 continues to move downward under the action of the moving block 400, causing the pressure inside the third hydraulic chamber 801 to continue to increase and be transmitted to the hydraulic device 605 connected to the third hydraulic chamber 801. However, the force-receiving rod 606 is restricted by the arc-shaped plate 604 and cannot move, causing the liquid pressure to move toward the side close to the moving rod 607, driving the outer plate 609 to squeeze the second elastic telescopic rod 610 and continue to apply an additional force to the friction inner plate 611.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
