[0026] Existing wind turbine equipment monitoring devices are easily damaged by impacts from objects in severe weather (such as tree branches and hail) due to prolonged exposure to the external environment, especially when installed at high altitudes, affecting their normal operation and data acquisition accuracy. Furthermore, dust and contaminants accumulate on the lens surface, leading to blurred images and reduced monitoring effectiveness. The high installation location also increases the difficulty and cost of maintenance and cleaning. Therefore, the inventors have developed a wind turbine equipment monitoring device that, by incorporating a cleaning component, not only provides closed protection against damage from external impacts during severe weather but also automatically cleans the lens when the device is idle, removing dust and contaminants to ensure image clarity and monitoring effectiveness. This improves the overall cleanliness of the equipment, reduces maintenance frequency, extends service life, and significantly enhances the reliability and durability of the monitoring device under various environmental conditions, thereby solving the aforementioned deficiencies.

A mounting box 34 is fixedly connected to the front of the bottom of the protective housing 2. A motor 35 is installed inside the mounting box 34. A rotating rod 36 is fixedly connected to the output shaft of the motor 35. The front end of the rotating rod 36 extends to the outer side of the front of the mounting box 34 and is fixedly connected to a rotating plate 37. The contact area between the rotating rod 36 and the mounting box 34 is sealed to prevent external dust from entering the mounting box 34. Inside the cavity, a brush 38 is fixedly connected to the outer surface of the rear side of the rotating plate 37. The outer surface of the rear side of the brush 38 contacts the lens of the monitoring device body 33. The front side of the monitoring device body 33 is embedded in the inner cavity of the front side of the protective box 2. The front side of the protective box 2 has a through cavity for placing the monitoring device body 33. A placement box 39 is fixedly connected to the front side of the bottom of the protective box 2. A miniature air pump 310 is installed in the inner cavity of the placement box 39. The air inlet of the miniature air pump 310 extends to the outer side of the left side of the inner cavity of the placement box 39. The inner cavity of the air end is equipped with a dustproof screen to prevent dust from entering the micro air pump 310. The air outlet of the micro air pump 310 is connected to an air pipe 311, and both ends of the air pipe 311 extend to the outer sides of the inner cavity of the placement box 39. The two ends of the air pipe 311 away from the micro air pump 310 are respectively equipped with nozzles 312, and the nozzles of the nozzles 312 are used in conjunction with the brush 38 to facilitate the blowing of dust off the surface of the brush 38, thereby improving the cleanliness of the brush 38. A positioning box 313 is fixedly connected to the left side of the bottom of the protective box 2.
[0029] Please refer to Figures 2 to 8A motor 314 is installed inside the positioning box 313. A running rod 315 is rotatably connected to the positioning box 313. The rear end of the running rod 315 is connected to the output shaft of the motor 314. Guide rods 316 are connected to both the left and right sides of the inner cavity of the protective box 2. The outer surface of the guide rod 316 located on the left side of the inner cavity of the protective box 2 is provided with several external threads. The bottom end of the guide rod 316 penetrates into the inner cavity of the positioning box 313 and is rotatably connected to the bottom of the inner cavity of the positioning box 313. Two meshing bevel gears 317 are respectively connected to the outer surfaces of the guide rod 316 and the running rod 315. A moving block 318 is movably connected to the outer surface of the guide rod 316. The moving block 318 connected to the left guide rod 316 is connected to... The contact area of the guide rod 316 is provided with a matching internal thread, so as to be threadedly connected with the guide rod 316. The outer surface of the moving block 318 is slidably connected to the inner cavity of the protective box 2. An L-shaped rod 319 is fixedly connected to the top of the moving block 318. The top end of the L-shaped rod 319 extends to the outer side of the top of the protective box 2 and is fixedly connected to the protective plate 320. The rear side of the protective plate 320 is slidably connected to the front side of the protective box 2. A heating coil 321 is embedded in the inner cavity of the front side of the monitoring device body 33, so that the lens of the monitoring device body 33 can be auxiliaryly heated by the heating coil 321, thereby avoiding fog or water vapor from blurring the lens of the monitoring device body 33. The protective plate 320 is used in conjunction with the front side of the monitoring device body 33.
[0030] Specifically, in the event of severe weather, the electric telescopic rod 31 is activated, and its output end retracts to retract the monitoring device body 33 into the protective box 2. Subsequently, the motor 314 starts, driving the guide rod 316 to rotate. Utilizing the threaded transmission principle, the moving block 318 moves up and down, which in turn drives the protective plate 320 downwards to close the through cavity on the front side of the protective box 2 via the L-shaped rod 319, effectively preventing external dust and rainwater from entering the protective box 2 and enhancing the protection of the monitoring device body 33. When it is necessary to clean the dust on the lens of the monitoring device body 33, the monitoring device body 33 is first moved to the outside of the front side of the protective box 2 using the electric telescopic rod 31. Then, the motor 35 is started, and the motor 35 drives the rotating rod 36 and the brush 38 on the rotating plate 37 to clean the lens, preventing dust from accumulating. If the brush 38 has been used for an extended period, the micro air pump 310 can be activated to transmit air through the air pipe 311 to the nozzle 312, blowing air onto the horizontally positioned brush 38 to remove dust accumulated on its surface, maintaining its cleanliness and ensuring its effectiveness for subsequent use. This not only improves the equipment's protection and cleaning efficiency but also extends the lifespan of the monitoring device.
[0031] In summary, the working principle of a wind turbine equipment monitoring device according to this utility model embodiment is as follows: First, the user installs the mounting bracket 1 and the monitoring device body 33 in a suitable monitoring position on the wind turbine equipment. Then, when facing severe weather, the user activates the cleaning component 3, which drives the monitoring device body 33 to retract and close for protection, thereby avoiding damage to the monitoring device body 33 caused by the external environment. When placing the device, the user can also activate the cleaning component 3 to clean the lens of the monitoring device body 33 for easy use.
