[0023] In this embodiment, when the safety monitoring device is used in the operation and maintenance of the power transmission line, after the body 501 is installed at the position of the transmission line, the key parameters such as the current and voltage at the position of the transmission line can be monitored in real time. At the same time, with the use of the camera 502, the camera 502 can clearly capture the image of the transmission line, thereby realizing the monitoring of abnormal conditions such as ice coating and foreign objects on the transmission line. When it is necessary to inspect and maintain the monitoring device installed at a high position on the power tower, the starting motor 403 drives the rotating shaft 404 to rotate accordingly. When the rotating shaft 404 rotates, it can drive the first synchronous wheel 405 to rotate accordingly. The synchronous wheel 405 can drive the support shaft 402 to rotate by the connection of the belt 407 and the second synchronous wheel 406. The rotation of the support shaft 402 can drive the spool 408 to rotate for unwinding. At this time, the traction rope 409 is unwound, and the electric push rod 412 is started to drive the push plate 413 to move downward. After the push plate 413 moves downward, it exerts downward pressure on the mounting plate 411, so that the machine body 501 is separated from the limit of the second friction plates 604 on both sides. As the traction rope 409 continues to unwind, the machine body 501 will slowly move downward toward the ground. When the machine body 501 drops to the ground, the staff can directly When the machine body 501 is repaired and maintained, there is no need for the staff to climb to a high altitude to repair and maintain the monitoring device, which effectively reduces the maintenance cost of the safety monitoring device. At the same time, compared with high-altitude operations, it effectively reduces the safety risk of power maintenance work. After completing the repair and maintenance work, the motor 403 is started to run in the reverse direction to drive the machine body 501 to move up and reset. As the machine body 501 continues to move up, the hair roller 706 can be driven to rotate. At this time, the hair roller 706 can be used to brush off the dust and foreign matter attached to the surface of the machine body 501 during the upward movement, so as to avoid affecting the normal use of the machine body 501. As the machine body 501 continues to move upward, the machine body 501 contacts the bottom inclined surface of the movable plate 603 when moving upward, and the movable plate 603 can be pushed toward the inner wall of the lower box body 2. At this time, the movement of the movable plate 603 causes the telescopic rod 601 and the first spring 602 to be compressed, and the machine body 501 will move to the use position corresponding to the second friction plate 604. The rebound force of the first spring 602 can make the second friction plate 604 and the first friction plate 504 be in a tightly fitted state. At this time, the friction force generated by the contact between the second friction plate 604 and the first friction plate 504 can support the position of the machine body 501.

[0024] Embodiment 2 Figure 1 and Figure 8As shown, a plurality of second springs 702 are equidistantly fixedly connected to the inner surface of the side frame 701, a supporting plate 703 is fixedly connected between the end surfaces of the plurality of second springs 702, a support plate 703 is symmetrically fixedly connected to the outer surface of the supporting plate 703, a support rod 705 is rotatably connected to the inner surface of the support rod 704, a hair roller 706 is fixedly connected to the outer surface of the support rod 705, the hair roller 706 is matched with the position of the machine body 501, a mounting rod is symmetrically fixedly connected to the inner surface of the box body 2, the end surfaces of the two mounting rods are fixedly connected to a limiting ring 8, the limiting ring 8 is located between the spool 408 and the mounting plate 411, and the traction rope 409 is located on the inner side of the limiting ring 8.

[0025] In this embodiment, when the traction rope 409 is retracted or released, the moving path of the traction rope 409 will be limited by the limiting ring 8, that is, the moving path of the traction rope 409 can be limited by the limiting ring 8, so that the mounting plate 411 corresponding to the traction rope 409 is in a relatively stable state during lifting, thereby improving the stability of the device during lifting operation.

[0026] Embodiment 3 Figure 5 and Figure 6 As shown, a camera 502 is fixedly connected to the front surface of the body 501, an operation panel 503 is fixedly connected to the front surface of the body 501, first friction plates 504 are fixedly connected to the outer surfaces of both sides of the body 501, a soft pad 505 is fixedly connected to the bottom of the body 501, and a vortex fan 506 is fixedly connected to the rear surface of the body 501.

[0027] In this embodiment, after the machine body 501 moves down and leaves the position of the box body 2, the machine body 501 is in a suspended state supported by the traction rope 409. Under the influence of the airflow in the air, the machine body 501 will shake. In order to prevent the machine body 501 from shaking toward the power tower and causing a collision, the vortex fan 506 at the rear of the machine body 501 is used. When the machine body 501 is about to approach the power tower, starting the vortex fan 506 can generate a reverse thrust on the machine body 501, thereby preventing the machine body 501 from being damaged by a collision during the descent, and improving the stability of the displacement state of the machine body 501 during the lifting and moving. When the machine body 501 is lowered to the ground, the setting of the soft pad 505 can play a supporting role.

[0028] The use method and working principle of this device: When the safety monitoring device is used in the operation and maintenance of the power transmission line, the safety monitoring device is installed in conjunction with the power tower. At this time, the monitoring device is at a high place, that is, the laying position of the transmission line. After the body 501 is installed at the transmission line position, the key parameters such as the current and voltage at the transmission line position can be monitored in real time. At the same time, with the use of the camera 502, the camera 502 can clearly capture the image of the transmission line, thereby realizing the monitoring of abnormal conditions such as ice coating and foreign objects on the transmission line. When it is necessary to inspect and maintain the monitoring device installed at a high place on the power tower, through the use of the lifting component 4, the body 501 can be sent to the ground position by utilizing its lifting and winding function, which is convenient for the staff at the ground position The machine body 501 is directly inspected and maintained. When inspecting and maintaining the machine body 501, the motor 403 is started. The operation of the motor 403 can drive the rotating shaft 404 to rotate. When the rotating shaft 404 rotates, the first synchronous wheel 405 can drive the supporting shaft 402 to rotate through the connection of the belt 407 and the second synchronous wheel 406. The rotation of the supporting shaft 402 can drive the spool 408 to rotate for unwinding. At this time, the traction rope 409 is unwinding, and the electric push rod 412 is started at the same time. After the electric push rod 412 runs and extends, it can drive the push plate 413 to move downward. After the push plate 413 moves downward, it applies downward pressure to the mounting plate 411, so that the machine body 501 is separated from the second friction plates 604 on both sides. The machine body 501 is suspended in the air and supported by the traction rope 409. The airflow in the air causes the machine body 501 to shake. In order to prevent the machine body 501 from shaking toward the power tower and causing collision, the vortex fan 506 at the rear of the machine body 501 is used. When the machine body 501 is about to approach the power tower, the vortex fan 506 is started to generate a reverse thrust on the machine body 501, thereby preventing the machine body 501 from being damaged by collision during the descent, thereby improving the stability of the displacement state of the machine body 501 during the lifting and moving. When the machine body 501 is lowered to the ground, the cushion 505 is used to The setting can play a supporting role, and the staff can directly perform maintenance operations on the machine body 501 at the ground position, without the need for the staff to climb to a high altitude position to perform maintenance operations on the monitoring device, which effectively reduces the maintenance cost of the safety monitoring device. At the same time, compared with high-altitude operations, it effectively reduces the safety risk of power maintenance work. After completing the maintenance work, start the motor 403 to run in the reverse direction to drive the machine body 501 to move up and reset. When the machine body 501 moves up and passes the position of the side frame 701, the surface of the machine body 501 will be in contact with the hair roller 706. At this time, the resilience of the second spring 702 can be used to apply pressure to the support plate 703 in the direction of the machine body 501, so that the hair roller 706 and the surface of the machine body 501 are in a close contact state.At the same time, as the machine body 501 continues to move upward, the hair roller 706 can be driven to rotate. At this time, the hair roller 706 can be used to brush off the dust and foreign matter attached to the surface of the machine body 501 during the upward movement, so as to avoid affecting the normal use of the machine body 501. As the machine body 501 continues to move upward, the machine body 501 contacts the bottom inclined surface of the moving plate 603 when moving upward, and the moving plate 603 can be pushed toward the inner wall of the lower box body 2. At this time, the movement of the moving plate 603 causes the telescopic rod 601 and the first spring 602 to be compressed, and the machine body 501 will move. When the second friction plate 604 is in the use position corresponding to the second friction plate 604, the rebound force of the first spring 602 can make the second friction plate 604 and the first friction plate 504 in a tightly fitted state. At this time, the friction force generated by the contact between the second friction plate 604 and the first friction plate 504 can support the position of the machine body 501. The pulling force caused by the machine body 501 on the traction rope 409 is small. When the machine body 501 is used for a long time at a high place, the position stability of the machine body 501 is improved, and the service life of the traction rope 409 can be increased.

[0029] The wiring diagram of the motor 403, the electric push rod 412, the body 501, the camera 502, the operating panel 503 and the eddy current fan 506 in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor 403, the electric push rod 412, the body 501, the camera 502, the operating panel 503 and the eddy current fan 506 will not be explained in detail.
