DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0021] Referring to Figures 1-5As shown in the figure, a substation maintenance auxiliary device includes a telescopic rod 1. A through groove 2 is formed inside the telescopic rod 1. A wire winding mechanism 3 is fixedly installed at the lower end of the telescopic rod 1. A nylon rope 20 is arranged inside the wire winding mechanism 3. A connecting plate 4 is fixedly installed at the upper end of the telescopic rod 1. A limiting groove 5 is formed through the inside of the connecting plate 4. A sliding groove 6 is formed on the inner wall of the limiting groove 5. A slider 7 is arranged inside the sliding groove 6. One end of the nylon rope 20 is fixedly connected to the slider 7. The wire winding mechanism 3 drives the slider 7 to move along the length direction of the sliding groove 6 by contracting the nylon rope 20. A guiding rod 8 is fixedly installed at the top of the inner wall of the limiting groove 5. Limiting rods 9 corresponding to the limiting groove 5 are fixedly installed on both sides of the slider 7. A rotating shaft 10 is rotatably installed at the upper end of the connecting plate 4 corresponding to the limiting groove 5. A fixing rod 11 is sleeved on the outer surface of the rotating shaft 10. A transmission rod 12 is sleeved on the outer surface of the limiting rod 9 corresponding to the fixing rod 11. The transmission rod 12 and the fixing rod 11 are connected by a hinge. One end of the transmission rod 12 moves downward by the movement of the slider 7, so that the fixing rod 11 rotates around the transmission shaft. A camera 13 is fixedly installed at one end of the fixing rod 11 away from the connecting plate 4. The fixing rod 11 drives the camera 13 to adjust to different positions, and the camera 13 is used to inspect complex areas such as the monitoring room, equipment room and office in the substation.

[0022] It should be noted that the camera 13 can be connected to the communication network by using wireless communication technologies such as WAPI and LoRa. WAPI (Wireless LAN Authentication and Privacy Infrastructure) is a reliable broadband communication technology with many advantages. First of all, WAPI has a high bandwidth rate and can support a large amount of data transmission and various service applications. By adopting advanced encryption algorithms and authentication mechanisms, WAPI can effectively protect the privacy and security of network communication, prevent information from being stolen or tampered with, and at the same time reduce the technology introduction and maintenance costs. LoRa has a large coverage, low terminal power consumption, low price, can be integrated with sensors, and can be deployed anywhere at any time. However, its security is relatively low, the industrial chain is limited, and the rate is low. It is more suitable for narrowband aggregation of operation monitoring services in scenarios with low power consumption and few terminals for maintenance (the battery is replaced once every three years). By connecting the camera to the main network by using wireless communication technologies such as WAPI or LoRa, the requirements for cables are reduced, and flexible on-demand deployment of in-station cameras can be realized. At the same time, the wireless communication technology is combined with the wired communication technology to complete the networking of the entire auxiliary monitoring system. The wired communication technology is mainly used for networking of the control box of the wall-mounted robot. The wired communication is mainly realized through the xPON network. The construction and deployment of the xPON network are relatively simple, and network coverage and service access can be quickly realized.

[0023] As Figures 1-5As shown in the figure, the wire winding mechanism 3 includes a main board 14. A rotating groove 15 corresponding to the through groove 2 is formed through the inside of the main board 14. An internal gear 16 is fixedly installed on the inner wall of the rotating groove 15. A rotating rod 17 is movably installed on the inner wall of the rotating groove 15 corresponding to the internal gear 16. A spur gear 18 corresponding to the internal gear 16 is fixedly installed on the outer surface of the rotating rod 17. Two support plates 19 are fixedly installed on the inner wall of the rotating groove 15. The two support plates 19 are symmetrically distributed about the center line of the through groove 2. A nylon rope 20 is sleeved on the outer surface of the rotating rod 17 between the two support plates 19. The wire winding mechanism 3 includes a main board 14. A rotating groove 15 corresponding to the through groove 2 is formed through the inside of the main board 14. An internal gear 16 is fixedly installed on the inner wall of the rotating groove 15. A rotating rod 17 is movably installed on the inner wall of the rotating groove 15 corresponding to the internal gear 16. A spur gear 18 is fixedly installed on the outer surface of the rotating rod 17. Two support plates 19 are fixedly installed on the inner wall of the rotating groove 15. The two support plates 19 are symmetrically distributed about the center line of the through groove 2. A nylon rope 20 is sleeved on the outer surface of the rotating rod 17 between the two support plates 19. When the rotating rod 17 drives the spur gear 18 away from the internal gear 16, the rotating rod 17 drives the nylon rope 20 to contract through rotation, thereby moving the slider 7. After the slider 7 moves to a suitable position, the rotating rod 17 pushes the spur gear 18 into the internal gear 16 to prevent the rotating rod 17 from rotating, thereby fixing the slider 7 at a suitable position.

[0024] As Figures 1-5 shown, a circular plate 21 is provided on the outer side of the main board 14 corresponding to the rotating rod 17. The rotating rod 17 penetrates through the main board 14 and is fixedly connected to the circular plate 21. A handle 22 is rotatably installed on one side of the circular plate 21 away from the rotating rod 17. The staff moves the circular plate 21 to move the rotating rod 17 and rotates the circular plate 21 through the handle 22.

[0025] As Figures 1-5 shown, a spring 23 is sleeved on the outer surface of the guide rod 8. The two ends of the spring 23 are respectively fixedly connected to the top of the inner wall of the limit groove 5 and the upper surface of the slider 7. The spring 23 constantly gives a pulling force to the slider 7 so that the slider 7 can...

[0026] As Figures 1-5 shown, the sliding groove 6 is communicated with the rotating groove 15 through the through groove 2. The nylon rope 20 sequentially enters the surface of the rotating rod 17 through the sliding groove 6 and the through groove 2.

[0027] As Figures 1-5 shown, both of the two support plates 19 are rotatably connected to the rotating rod 17. While the support plates 19 support the rotating rod 17, they do not prevent the rotation and movement of the rotating rod 17.

[0028] As Figures 1-5 shown, the spur gear 18 corresponds to the internal gear 16. The spur gear 18 enters the internal gear 16, thereby fixing the rotating rod 17.

[0029] Working principle: The staff can move the connecting plate 4 to a suitable position through the telescopic rod 1. At the same time, the spring 23 drives the slider 7 to contact the guide rod 8, so that the fixed rod 11 is in a horizontal state. The staff can observe the state at the high place of the substation through the camera 13. When adjusting the position, the staff moves the circular plate 21, so that the straight-tooth gear 18 disengages from the internal gear 16. The handle 22 drives the circular plate 21 to rotate, so that while the rotating rod 17 drives the nylon rope 20 to wind up, the slider 7 moves, and one end of the transmission rod 12 moves downward, so that the fixed rod 11 rotates around the transmission shaft. When the fixed rod rotates to a suitable position, the staff pushes the rotating rod 17 on the circular plate 21 to move, and the rotating rod 17 drives the straight-tooth gear 18 to enter the internal gear 16, so that the rotating rod 17 is fixed, making it more rapid and convenient to adjust the camera for information collection.

[0030] Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
