[0029] The following will be combined with the drawings in the embodiments of 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, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. 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.

[0030] like Figures 1 to 5As shown, an embodiment of the present invention provides a wind measuring device, which includes a base 10, a wind measuring piece 20 and a lifting assembly 30. The wind measuring piece 20 is vertically liftably arranged on the base 10. The lifting assembly 30 includes a driving piece 31, an active bevel gear 32, a driven bevel gear 33 and a rotating piece 34. The driving piece 31 is arranged on the base 10 and is drivingly connected to the active bevel gear 32 to drive the active bevel gear 32 to rotate relative to the base 10 around its transverse axis. The driven bevel gear 33 is rotatably arranged on the base 10 around its vertical axis. The active bevel gear 32 and the driven bevel gear 33 are meshed. The rotating piece 34 is connected to the driven bevel gear 33 and is coaxially arranged. The rotating piece 34 is threadedly matched with the wind measuring piece 20.

[0031] The wind measuring device provided by the present embodiment includes a base 10, a wind measuring member 20 and a lifting assembly 30. The wind measuring member 20 is used to detect wind force. When it is necessary to detect wind force at different heights, the driving member 31 is used to drive the active bevel gear 32 to rotate, and the active bevel gear 32 is meshed with the driven bevel gear 33 to drive the rotating member 34 to rotate around its vertical axis. Since the rotating member 34 is threadedly matched with the wind measuring member 20, the wind measuring member 20 is lifted and moved to adjust the height of the wind measuring member 20 relative to the base 10. Therefore, the wind measuring device can adjust the height of the wind measuring member 20 relative to the base 10 by using the lifting assembly 30, and can detect wind force at different heights, thereby improving the practicality, detection effect and work efficiency of the wind measuring device. In addition, the wind measuring device can use the lifting assembly 30 to lower the height of the wind measuring member 20 (i.e., the wind measurement height) during the freezing period, without the need for manual tower climbing operation, thereby improving the safety of the wind measuring device.

[0032] Specifically, the driving member 31 includes a driving motor.

[0033] like Figure 1 , Figure 2 as well as Figure 5 As shown, the wind measuring device further includes a lifting guide structure 40 disposed between the base 10 and the wind measuring member 20. Since the wind measuring device is in a wind field environment, by providing the lifting guide structure 40, when the height of the wind measuring member 20 relative to the base 10 can be adjusted by using the lifting assembly 30, the stability of the lifting movement of the wind measuring member 20 relative to the base 10 can be improved.

[0034] like Figure 1 , Figure 2 as well as Figure 5 As shown, the lifting guide structure 40 includes a guide cylinder 41 and a guide column 42. The guide cylinder 41 extends in the vertical direction and is arranged on the base 10. The guide column 42 extends in the vertical direction and is connected to the wind measuring member 20. The guide column 42 is movably arranged in the guide cylinder 41 in the vertical direction, and the guide column 42 is anti-rotatably matched with the guide cylinder 41. The above-mentioned lifting guide structure 40 has the advantage of simple structure.

[0035] Specifically, a threaded hole 421 is provided at the lower end of the guide column 42 , and the rotating member 34 is passed through the threaded hole 421 and threadably engaged with the threaded hole 421 .

[0036] like Figure 2 As shown, the guide cylinder 41 includes a cylinder body 411 and a top plate 412. The cylinder body 411 extends in the vertical direction and is arranged on the base 10. The top plate 412 is arranged at the upper end of the cylinder body 411. A guide hole is arranged on the top plate 412. The guide column 42 is movably arranged in the guide hole in the vertical direction. The guide column 42 is engaged with the guide hole to prevent rotation. The cylinder body 411, the top plate 412 and the base 10 are surrounded by a receiving cavity. The active bevel gear 32, the driven bevel gear 33 and the rotating member 34 are all arranged in the receiving cavity. By arranging the active bevel gear 32, the driven bevel gear 33 and the rotating member 34 in the receiving cavity, the guide cylinder 41 can be used to protect the transmission structure of the lifting assembly 30, and improve the compactness of the arrangement between the lifting assembly 30 and the lifting guide structure 40.

[0037] Among them, the lower end of the cylinder 411 is detachably connected to the base 10, and a sealing ring is arranged between the lower end of the cylinder 411 and the base 10, so that the transmission structure of the lifting assembly 30 can be exposed by disassembling the cylinder 411, which is convenient for disassembly and maintenance. The sealing ring is used to seal the gap between the lower end of the cylinder 411 and the base 10 to prevent rainwater or accumulated water from entering the accommodating cavity through the gap between the lower end of the cylinder 411 and the base 10. The base 10 is also provided with a drainage channel connected to the accommodating cavity to discharge the accumulated water in the accommodating cavity.

[0038] In this embodiment, a guide rail extending in the vertical direction is provided on the outer wall of the guide column 42, and a ball is provided on the hole wall of the guide hole. The ball is embedded in the guide rail and slidably cooperates with the guide rail. When the lifting assembly 30 is used to adjust the height of the wind measuring piece 20 relative to the base 10, the smoothness of the lifting and lowering of the guide column 42 relative to the guide cylinder 41 can be improved.

[0039] like Figure 1 As shown, the wind measuring member 20 includes a lifting platform 21 and an anemometer 22. The lifting platform 21 is vertically liftable on the base 10.

[0044] like Figure 4 As shown, the bird repellent box 25 includes a box body 251, a medicine box 252 and a fan 253. The box body 251 is arranged on the lifting platform 21. The box body 251 has a diffusion cavity and a first diffusion hole 2511 connected to the diffusion cavity. The medicine box 252 and the fan 253 are both arranged in the diffusion cavity. The medicine box 252 has a second diffusion hole connected to the diffusion cavity. The medicine box 252 is filled with bird repellent, which diffuses into the diffusion cavity through the second diffusion hole. The air containing the bird repellent in the diffusion cavity is exchanged with the outside through the first diffusion hole 2511, so that the bird repellent drives away the surrounding birds and insects, and the fan 253 is used to accelerate the gas exchange between the diffusion cavity and the outside.

[0045] In this embodiment, the bird repellent box 25 further includes a concentration detection element disposed on the outside of the box body 251 to detect the concentration of the bird repellent agent. When the detection result of the concentration detection element is lower than a set value, the bird repellent agent in the agent box 252 is replaced or supplemented.

[0046] Specifically, the fan includes a rotating motor and fan blades. The rotating motor is disposed in the box body 251 . The rotating motor is drivingly connected to the fan blades to drive the fan blades to rotate so that the diffusion chamber exchanges gas with the outside through the first diffusion hole 2511 .
