Therefore, it is increasingly valued by countries around the world. With the growing global demand for renewable energy, wind power generation as a clean and renewable energy form has received widespread attention and development.

[0037] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind to generate electricity. Using wind power to generate electricity is very environmentally friendly and has huge wind energy reserves. Therefore, it is increasingly valued by countries around the world. With the growing global demand for renewable energy, wind power generation has received widespread attention and development as a clean and renewable energy form. In wind power generation systems, accurately detecting wind parameters is crucial to optimizing the performance of wind turbines, improving power generation efficiency, and ensuring the safe operation of the system. Please refer to Figure 1-Figure 7 As shown, this embodiment provides a wind force detection device for wind power generation, including a support base 100, four rollers 110 are fixedly connected to the bottom of the support base 100, a mobile frame 300 is provided above the support base 100, a rotation speed detection device 310 is fixedly connected to the top of the mobile frame 300, a fan 320 is rotatably connected to the end of the rotation speed detection device 310, and a counterweight 500 is contacted to the top of the support base 100;

[0040] The inner wall of the mobile frame 300 is provided with a lifting auxiliary fixing assembly 200 that enables the speed detection device 310 to detect wind force at different heights;

[0041] The bottom of the moving frame 300 is provided with an anti-sway component 400. When the rotation speed detection device 310 is at a high position, the tension generated by the connection between the bottom of the anti-sway component 400 and the top of the counterweight block 500 keeps the moving frame 300 in a stable state.

[0042] The roller 110 can be rotated by pushing the support base 100, and the support base 100 is moved to the position where the wind force needs to be detected and then stopped. The mobile frame 300 can be moved upward to the position where the wind force needs to be detected through the operation of the lifting auxiliary fixing component 200. If the position for detecting the wind force is relatively high, the anti-sway component 400 and the counterweight block 500 will be connected to generate a pulling force. This pulling force can effectively prevent the mobile frame 300 from shaking due to the strong wind at a high altitude, thereby keeping the mobile frame 300 in a stable state. At this time, the wind will blow the fan 320 to rotate, and the speed detection device 310 can detect the wind force according to the speed of the fan 320.

[0043] The present invention takes into account that when the lifting auxiliary fixing component 200 drives the mobile frame 300 to move to a higher position, strong wind may cause the mobile frame 300 to shake, affecting the accuracy and stability of the detection device. Therefore, the anti-sway component 400 through the bottom of the mobile frame 300 is in contact with the counterweight block 500. At this time, the anti-sway component 400 can obtain a stable downward pulling force, effectively resist the lateral effect of the wind, so that the mobile frame 300 remains stable, ensuring that the speed detection device 310 installed on the mobile frame 300 can operate normally, thereby improving the stability of the device. The combination of the anti-sway component 400 and the counterweight block 500 can adjust the weight of the counterweight block 500 according to actual conditions to adapt to different wind forces and environmental conditions.

[0044] Considering that the weight of the support base 100 itself is limited when the support base 100 supports the lifting auxiliary fixing assembly 200 to move the mobile frame 300 upward, it is difficult for the support base 100 to provide sufficient stability for the entire device in a windy environment. Therefore, by setting a counterweight block 500 on the top of the support base 100, the addition of the counterweight block 500 can significantly improve the stability of the support base 100. Under the action of strong winds, the heavier support base 100 can better resist the influence of wind force and reduce the shaking of the entire device.

[0045] In order to enable the lifting auxiliary fixing assembly 200 to drive the movable frame 300 to move upward, it is necessary to further disclose the parts of the lifting auxiliary fixing assembly 200. Therefore, the lifting auxiliary fixing assembly 200 includes a fixing frame 210 fixed on the top of the supporting base 100, the fixing frame 210 is rotatably connected to a screw rod 220, and a rotating device 230 for driving the screw rod 220 to rotate is fixedly connected to the bottom of the inner cavity of the fixing frame 210. The inner wall of the movable frame 300 is threadedly connected to the surface of the screw rod 220. The screw rod 220 can be driven to rotate by the operation of the rotating device 230, and the movable frame 300 can be driven to move by the rotation of the screw rod 220.

[0046] In order to enable the rotation of the screw rod 220 to drive the movable frame 300 to move in the vertical direction and not rotate with the rotation of the screw rod 220, a limiting groove 211 is provided on the surface of the fixed frame 210, and the surface of the movable frame 300 slides on the inner wall of the limiting groove 211. The rotation of the screw rod 220 can drive the movable frame 300 to be threadedly connected with it, and the limiting of the limiting groove 211 can make the movable frame 300 move in the vertical direction.

[0047] In order to enable the lifting auxiliary fixing assembly 200 to support and fix the moving frame 300, a first rotator 240 is fixedly connected to the surface of the fixed frame 210, a second rotator 242 is fixedly connected to the bottom of the moving frame 300, and a rotating rod 241 is rotatably connected between the inner wall of the first rotator 240 and the inner wall of the second rotator 242. The first rotator 240 and the second rotator 242 can be connected and fixed by the rotating rod 241 to provide auxiliary support for the moving frame 300.

[0048] Considering that the speed detection device 310 is set outdoors, the speed detection device 310 needs to be protected. Therefore, a protective frame 330 is fixedly connected to the top of the mobile frame 300, and the speed detection device 310 is located in the inner cavity of the protective frame 330. By setting the protective frame 330 on the top of the mobile frame 300, the surface of the speed detection device 310 can be protected.

[0049] In order to ensure that the anti-sway component 400 can prevent the mobile frame 300 from swaying at a high place, the parts of the anti-sway component 400 need to be further disclosed. Therefore, the anti-sway component 400 includes two connectors 410 fixedly connected to the bottom of the mobile frame 300, the inner wall of the connector 410 is fixedly sleeved with a fixer 420, the bottom of the fixer 420 is fixedly connected with a stretch elastic rope 430, and the end of the stretch elastic rope 430 away from the fixer 420 is fixedly connected with a hook 431. The stretch elastic rope 430 can be pulled by connecting the hook 431 with the counterweight block 500. At this time, the tension generated by the stretch elastic rope 430 can effectively prevent the mobile frame 300 from swaying due to the strong wind at a high place.

[0050] In order to connect the hook 431 to the counterweight 500, a connecting semicircular ring 510 is fixedly connected to the top of the counterweight 500. The connecting semicircular ring 510 is located below the hook 431. The hook 431 is pulled to be sleeved on the inner wall of the connecting semicircular ring 510. At this time, the weight of the counterweight 500 will stretch the elastic rope 430.

[0051] In order to fix the counterweight 500 at the top of the support base 100, the top of the support base 100 is fixedly connected to the limiting frame 600, and the counterweight 500 is arranged in the inner cavity of the limiting frame 600. The surface of the limiting frame 600 is hinged with a support plate 610 by means of a hinge. The support plate 610 can be separated from the limiting frame 600 by rotating it. At this time, the counterweight 500 can be placed in the inner cavity of the limiting frame 600.

[0052] Taking into account that in the process of moving the support base 100, the connection between the limit frame 600 and the support plate 610 only uses hinges, and the support plate 610 cannot be fixed to the limit frame 600, which will affect the movement of the support base 100. Therefore, two locking plates 601 are fixedly connected to the surface of the limit frame 600, and a lock body 612 is fixedly connected to the surface of the support plate 610. A fixing groove is opened on the surface of the lock body 612. The inner wall of the lock body 612 and the inner wall of the fixing groove are slidably connected with two fixing rods 613. The fixing rod 613 can be moved to contact the inner wall of the locking plate 601, and the fixing rod 613 is rotated to be fixed to the inner wall of the fixing groove, so as to fix the fixing rod 613.

[0053] In order to increase the contact area between the support base 100 and the ground, and considering that a roller 110 is arranged at the bottom of the support base 100, if the wind is strong, the roller 110 will roll, and at this time it will drive the support base 100 to move. Therefore, two support legs 611 are threadedly connected to the inner wall of the support plate 610. When the equipment is working, the support legs 611 are in contact with the ground, which increases the friction with the ground and can effectively prevent the roller 110 from rolling due to wind force, ensuring that the support base 100 stays stably in the desired position, providing reliable support for the entire wind detection equipment.

[0054] The working principle of the present invention is as follows: the roller 110 can be rotated by pushing the support base 100, and the support base 100 is moved to the position where the wind force needs to be detected and then stopped. The screw rod 220 can be driven to rotate through the operation of the rotating device 230, and the rotation of the screw rod 220 can drive the movable frame 300 to be threadedly connected with it. The movable frame 300 can be moved in the vertical direction through the limiting groove 211, and the first rotator 240 can be connected with the second rotator 242 through the rotating rod 241 to provide auxiliary support for the movable frame 300. At the same time, after the movable frame 300 moves upward to the position where the wind force needs to be detected, if the position for detecting the wind force is higher, the fixing rod 613 is slid to separate it from the inner wall of the locking plate 601, and then the support plate 610 is rotated to make the surface support The support leg 611 is in contact with the ground, which increases the friction with the ground and can effectively prevent the roller (110) from rolling due to wind force, ensuring that the support base (100) stays stably at the desired position, providing reliable support for the entire wind force detection device. At this time, the counterweight block 500 can be placed in the inner cavity of the limit frame 600, and the hook 431 can be pulled to be sleeved on the inner wall of the connecting semicircular ring 510. At this time, the weight of the counterweight block 500 will stretch the elastic rope 430. At this time, the tension generated by the elastic rope 430 can effectively prevent the mobile frame 300 from shaking due to the strong wind force at a high altitude, thereby keeping the mobile frame 300 in a stable state. At this time, the wind will blow the fan 320 to rotate, and the speed detection device 310 can detect the wind force according to the speed of the fan 320.
