For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that: an intelligent dust cleaning mechanism is provided on the support frame 203, and the intelligent dust cleaning mechanism includes a sleeve dust wiping component, a wind-driven component, a lifting and lowering adjustment component, and a dust cleaning intelligent controller 345. The sleeve dust wiping component includes a support plate 301 and a support semi-ring 302 matching the protective cylinder 201. A matching end dust cleaning cloth piece 303 is fixedly connected to the support plate 301, and a matching semi-ring dust cleaning cloth piece 304 is fixedly connected to the inner wall of the support semi-ring 302. The protective cylinder 201 is configured to be cylindrical, and the end dust cleaning cloth piece 3 03 is set to a semicircular ring shape, the support plate 301 is set to a round cake shape, and the wind-driven component includes a support box 401, a vertical shaft 402 is penetrated on the top outer wall of the support box 401, and a horizontal shaft 403 is penetrated and embedded on the outer wall of the support box 401 close to the support plate 301. One end of the vertical shaft 402 is fixedly connected to a vertical bevel gear 404, and one end of the horizontal shaft 403 is fixedly connected to a horizontal bevel gear 405. The top of the vertical shaft 402 is fixedly connected to a blade shaft 406, and a plurality of wind-attracting blades 407 evenly distributed along a ring are fixedly connected to the outer wall of the blade shaft 406. The vertical shaft 402 and the horizontal shaft 403 are rotatably connected to the outer wall of the support box 401 through bearings, and the other end of the horizontal shaft 403 is fixedly connected to the support plate 301, and The connection point between the horizontal axis 403 and the support plate 301 is located at the center of the support plate 301, the vertical bevel gear 404 is vertically arranged with the horizontal bevel gear 405, and the vertical bevel gear 404 is meshed with the horizontal bevel gear 405, the vertical axis 402 passes through the support frame 203 and is slidably connected thereto, the lifting and lowering adjustment component includes an adjustment box 501 and a wind meter 502 fixedly installed on the top of the support frame 203, a drive adjustment motor 503 is fixedly installed in the adjustment box 501, a rope drum 504 is fixedly connected to the output end of the drive adjustment motor 503, a suspension rope 505 is wound on the rope drum 504, one end of the suspension rope 505 passes through the bottom outer wall of the adjustment box 501 and the support frame 203 and extends to be fixedly connected to the support box 401, and the suspension rope 505 is connected to the vertical bevel gear 405. The bottom outer wall of the regulating box 501 and the supporting frame 203 are all slidably connected. The dust cleaning intelligent controller 345 is provided with a lifting control module and an analysis master control module. The anemometer 502 is electrically connected to the analysis master control module, the analysis master control module is electrically connected to the lifting control module, and the lifting control module is electrically connected to the drive motor 503. The anemometer 502 can detect the wind speed, and the data detected by the anemometer 502 will be transmitted to the analysis master control module. When the wind speed is fast, that is, in strong winds, the analysis master control module will send instructions to the lifting control module, so that the lifting control module controls the drive motor 503 to unwind the suspension rope 505, so as to move the support box 401, the support plate 301, the support semi-ring 302, etc. downward.Until the semi-ring cleaning cloth piece 304 is sleeved onto the outer wall of the transparent cylinder 2002 and the end cleaning cloth piece 303 is in contact with the end of the transparent cylinder 2002, the wind force acts on the wind-inducing blade 407, which will cause the blade shaft 406 to rotate. The rotation of the blade shaft 406, under the transmission of the vertical shaft 402, the vertical bevel gear 404, the horizontal bevel gear 405, and the horizontal shaft 403, will drive the support plate 301 and the supporting semi-ring 302 to rotate around the horizontal shaft 403 as the central axis, so that the end cleaning cloth piece 303 and the semi-ring cleaning cloth piece 304 can clean the dust on the surface of the transparent cylinder 2002. After the wind stops, the analysis master control module The command will be sent to the lifting control module again, so that the horizontal axis 403 controls the drive motor 503 to reel the suspension rope 505, so that the support box 401, the support plate 301, the support half ring 302, etc. move upward and reset. Therefore, through the setting of the intelligent dust cleaning mechanism, the sleeve dust wiping component can clean the dust on the surface of the transparent cylinder 2002 in windy weather, thereby preventing dust from affecting the monitoring of the power equipment by the monitoring camera 001, improving the monitoring effect of the security monitoring equipment, and the sleeve dust wiping component is mainly driven by wind power to clean the dust, which can greatly reduce energy consumption and improve energy saving and environmental protection performance.

[0037] See also Figure 4-10The intelligent dust cleaning mechanism also includes an angle adjustment auxiliary sleeve component, which includes a signal transmitter 601 fixedly mounted on the support frame 203 and a signal receiver 602 fixedly mounted on the support half ring 302, the signal receiver 602 is located in the middle of the support half ring 302, the angle adjustment auxiliary sleeve component also includes an electromagnet 603 and a slide rail 604 fixedly mounted on the inner wall of the bottom end of the support box 401, an iron slide 605 is slidably connected to the slide rail 604, an angle adjustment motor 606 with a self-locking function is fixedly connected to the top of the iron slide 605, an elastic pull rope 610 is fixedly connected between the iron slide 605 and the inner wall of the support box 401, the angle adjustment auxiliary sleeve component also includes a transmission rod 607 fixedly mounted in the middle of the transverse bevel gear 405, the transmission rod A transmission slot 608 is provided on 607, and a transmission block 609 matching the transmission slot 608 is fixedly connected to the output end of the angle adjustment motor 606, and the transmission block 609 is set in a truncated cone shape. An angle adjustment control module is also provided in the dust cleaning intelligent controller 345, and the analysis master control module is electrically connected to the angle adjustment control module, and the angle adjustment control module is electrically connected to the signal transmitter 601, the electromagnet 603, and the angle adjustment motor 606, and the signal receiver 602 is electrically connected to the angle adjustment control module. In windy weather with sufficient wind force, before the analysis master control module sends a command to the lifting control module, it will first send a command to the angle adjustment control module. After receiving the command, the angle adjustment control module will first energize the electromagnet 603, and under the action of the magnetic attraction of the electromagnet 603, the iron slide plate 605 will be brought The angle adjustment motor 606 and the transmission block 609 move toward the direction close to the transverse bevel gear 405, so that the transmission block 609 is tightly against the transmission rod 607 through the transmission slot 608. Since the angle adjustment motor 606 has a self-locking function, after the transmission block 609 and the transmission rod 607 are against each other, the transverse bevel gear 405 can be locked under the action of friction, so that the transverse bevel gear 405 cannot rotate. Then the angle adjustment control module will start the signal transmitter 601, so that the signal transmitter 601 transmits a signal at a higher frequency. At the same time, the angle adjustment control module will also start the angle adjustment motor 606, so that the angle adjustment motor 606 slowly drives the transverse bevel gear 405 to rotate through the transmission block 609 and the transmission rod 607, thereby slowly driving the support plate 301 and the support semi-ring 302 rotates until the signal receiver 602 rotates to the bottom of the signal transmitter 601. At this time, the signal receiver 602 can receive the signal emitted by the signal transmitter 601. The moment the signal receiver 602 rotates to the bottom of the signal transmitter 601 and receives the signal, the angle adjustment control module will turn off the angle adjustment motor 606 to keep the support plate 301 and the support semi-ring 302 stationary so that the support semi-ring 302 is directly above the transparent cylinder 2002. Then, the analysis master control module will send a command to the lifting control module to move the support plate 301, the support semi-ring 302, etc. downward. After the semi-ring cleaning cloth 304 is sleeved on the outer wall of the transparent cylinder 2002, the angle adjustment control module will cut off the power to the electromagnet 603.This causes the iron slide plate 605, the angle adjustment motor 606, etc. to move and reset under the action of the elastic pull rope 610, thereby no longer restricting the rotation of the transverse bevel gear 405, and thus enabling the sleeve dust wiping assembly to clean the transparent cylinder 2002 under the drive of the wind. Similarly, after the wind stops, the angle adjustment auxiliary sleeve assembly can adjust the sleeve dust wiping assembly again, so that the semi-ring dust cleaning cloth piece 304 can be smoothly separated from the transparent cylinder 2002. Therefore, through the setting of the angle adjustment auxiliary sleeve assembly, the angle adjustment auxiliary sleeve assembly can adjust the sleeve dust wiping assembly before cleaning the transparent cylinder 2002, so that the semi-ring dust cleaning cloth piece 304 can be smoothly sleeved on the outer wall of the transparent cylinder 2002, so that the intelligent dust cleaning mechanism can smoothly remove dust on the surface of the transparent cylinder 2002, thereby improving practicality.

[0038] See also Fig. 9 The cleaning intelligent controller 345 is also provided with a signal receiving module based on Internet technology. The signal receiving module is electrically connected to the analysis master control module, and the analysis master control module is electrically connected to the electromagnet 603 and the angle adjustment motor 606. The staff can send instructions to the analysis master control module remotely through the Internet and the signal receiving module. If the staff needs to check the operating status of the equipment through the monitoring camera 001, but the intelligent cleaning mechanism is cleaning the transparent cylinder 2002, the staff can send relevant instructions to the analysis master control module to make the analysis master control module control the drive adjustment motor 5 03 drives the sleeve dust wiping assembly to move upward so that the end cleaning cloth 303, the semi-ring cleaning cloth 304, etc. are separated from the transparent cylinder 2002, so that the staff can check the operating status of the equipment. Similarly, if it is necessary to actively clean the transparent cylinder 2002 when there is no wind, the staff can also send relevant instructions to the analysis and control module. The analysis and control module can control the angle adjustment motor 606 to drive the sleeve dust wiping assembly to rotate, so as to actively clean the transparent cylinder 2002, so that the staff can remotely control the intelligent cleaning mechanism, which greatly improves the practicality.

[0039] See also Figure 4-5 The sleeve dust wiping assembly also includes a dust cover 305 fixedly connected to the support frame 203. The support plate 301, the support half ring 302, the support box 401, and the dust cleaning intelligent controller 345 are all located on the inner side of the dust cover 305. The dust cover 305 can play a dust-proof role to prevent dust from adhering to the end cleaning cloth piece 303 and the half ring cleaning cloth piece 304.
