[0002] With the rapid development of science and technology in my country, the number of smart grids and ultra-high voltage (UHV) projects is increasing, and they are gradually moving towards "automation, informatization, interactivity, and digitization." Therefore, when it comes to substation inspection, traditional inspection models are no longer able to adapt to the ever-changing development of the power grid. This situation means that the main challenge facing my country's power grid is how to use new technologies and new methods to promote the transformation of inspection models, while ensuring the safe operation of equipment and minimizing the inspection pressure on relevant professionals.

[0003] At present, in the existing power inspection, in order to realize the inspection of high-voltage wires at higher positions, the inspection robot is usually hung on the high-voltage wires to enable it to move and inspect the high-voltage wires. However, when the inspection robot moves to the power tower, due to the limitation of the power tower, the inspection robot cannot cross the power tower for inspection. At the same time, in a relatively harsh environment, the inspection robot is prone to get stuck on the high-voltage wires or even fall. For this reason, we propose a video image inspection device for power equipment. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] See also Figure 1-10 The present invention provides a technical solution: a video image inspection device for electric power equipment, comprising an infrared camera 1 for inspecting high-voltage power lines, a temperature and humidity sensor 11 provided on the infrared camera 1 for detecting temperature and humidity, the infrared camera 1 being provided with a slide rail 12, and the slide rail 12 being provided with two connecting mechanisms 2;

[0045] The stretching mechanism 24 includes a drive motor 241 fixedly connected to the outside of the connecting shell 23 through a waterproof shell. The output end of the drive motor 241 passes through one side of the connecting shell 23 and is fixedly connected to a drive gear 242. The output end of the drive motor 241 is rotatably connected to the connecting shell 23.

[0046] The outer side of the driving gear 242 is meshed with an upper gear bar 243 and a lower gear bar 244. The top and bottom ends of the connecting shell 23 are respectively provided with a moving opening 231 for moving the upper gear bar 243 and the lower gear bar 244. A protrusion 232 is installed at the moving opening 231, and the upper gear bar 243 and the lower gear bar 244 are both provided with a limiting groove at the corresponding protrusions.

[0047] The ends of the upper gear bar 243 and the lower gear bar 244 located outside the connecting shell 23 are fixedly connected to the two outer shells 3 respectively;

[0048] The connecting mechanism 2 is connected to two housings 3, which are sleeved on the outside of the high-voltage wires to be inspected, and a driving mechanism 4 is provided inside the housing 3;

[0049] The driving mechanism 4 includes a first motor 42 mounted on a side of the housing 3 close to the connecting shell 23, and an output end of the first motor 42 passes through a side of the housing 3 and is fixedly connected to a roller 41, and the roller 41 is rotatably arranged on the high-voltage wire;

[0050] Therefore, when the high-voltage wire is being inspected, the four shells 3 are sleeved on the outside of the high-voltage wire in pairs, and the shells 3 are distributed up and down. At the same time, the shells 3 are sleeved on the outside of the high-voltage wire, and the shells 3 move on the high-voltage wire through the rollers 41. When the infrared camera 1 detects that it has moved to the positioning guide rail 7, the drive motor 241 is operated, thereby rotating the drive gear 242 inside the connecting shell 23. When the drive gear 242 rotates, the upper gear bar 243 and the lower gear bar 244 are driven to move in opposite directions, further causing the two shells 3 to move along the guide wheel 62 to the length of the support plate 72, and the two shells 3 are separated from the outside of the high-voltage wire respectively.

[0051] A secondary fixing mechanism 5 is provided on one side of the four housings 3 that are away from each other, and the secondary fixing mechanism 5 enables the two housings 3 to be stably sleeved on the outside of the high-voltage wire;

[0052] The secondary fixing mechanism 5 includes two arc-shaped guide sleeves 51 sleeved on the outside of the high-voltage wire. The two arc-shaped guide sleeves 51 are provided with through holes, and the two arc-shaped guide sleeves 51 are wrapped around the outside of the high-voltage wire. The sides of the two arc-shaped guide sleeves 51 that are in electrical contact with the high voltage are made of soft materials such as rubber to avoid damage to the high-voltage wire. The side of the arc-shaped guide sleeve 51 away from the housing 3 is a tapered end 52, and a plurality of push racks 53 are arranged around the tapered end 52.

[0053] The outer side of the arc-shaped guide sleeve 51 is fixedly connected to two connecting plates 54, and a slide rod 55 is slidably passed through the two connecting plates 54. One end of the two slide rods 55 is fixedly connected to the housing 3, and the other ends of the two slide rods 55 are fixedly connected to a limit plate 56.

[0054] A buffer spring 57 is sleeved on the outside of the slide rod 55, and both ends of the buffer spring 57 are fixedly connected to the housing 3 and the connecting plate 54 respectively;

[0055] When the infrared camera 1 moves along the high-voltage wire, the two arc-shaped guide sleeves 51 located in the moving direction are sleeved on the outside of the high-voltage wire to wrap and fix the high-voltage wire. At the same time, the tapered end 52 can remove dust and impurities on the outside of the high-voltage wire, even in bad weather, such as when there is ice attached to the outside of the high-voltage wire, thereby assisting the multiple rollers 41 to move stably along the high-voltage wire.

[0056] A guide transfer mechanism 6 is provided on the side of the housing 3 close to the power tower, and a positioning guide rail 7 is provided on the power tower. Multiple guide transfer mechanisms 6 pass the infrared camera 1 through the power tower through the positioning guide rail 7 to inspect the next section of high-voltage power lines. The positioning guide rail 7 includes a bracket 71 installed on the power tower. The bracket 71 is provided with a reinforcing rib, thereby enhancing the supporting force of the bracket 71, and a support plate 72 is installed on the bracket 71. A protective cover 10 for protecting the limiting rail 73 is installed on the support plate 72. Two limiting rails 73 are provided on the side of the support plate 72 close to the infrared camera 1, and the two limiting rails 73 are symmetrically distributed;

[0057] The limiting rail 73 is provided with a rail groove 731 for moving the limiting roller 64, and when moving, the guide wheel 62 is rolled on the support plate 72, and the two limiting rails 73 form an uphill alignment section 74, an intermediate moving section 75 and a downhill separation section 76 between each other. Through the uphill alignment section 74, the intermediate moving end and the downhill separation section 76, the roller 41 is stably separated, and the multiple guide wheels 62 are stably moved along the support plate 72;

[0058] The bottom end of the middle part of the support plate 72 is provided with a protective shell 77, and the protective shell 77 is connected to a wiping mechanism 8. When the infrared camera 1 moves to the protective shell 77, the wiping mechanism 8 wipes the camera head of the infrared camera 1.

[0059] The guide transfer mechanism 6 includes two fixed plates 61 fixedly connected to the outside of the housing 3, a guide wheel 62 is connected between the two fixed plates 61, and a second motor 63 for driving the guide wheel 62 is installed on the upper fixed plate 61;

[0060] A limiting roller 64 is installed on the fixing plate 61 located below.

[0061] The wiping mechanism 8 includes a lens wiping cotton 81 provided on the protective shell 77, and a rear plate 82 is installed on the side of the lens wiping cotton 81 away from the protective shell 77. The rear plate 82 is provided with a threaded hole, and a threaded rod 83 that passes through the rear plate 82 is rotatably connected to the protective shell 77;

[0062] The end of the threaded rod 83 located above the protective shell 77 is equipped with a transmission mechanism 9 for reciprocating rotation.

[0063] The transmission mechanism 9 includes a first forward gear 91 fixedly connected to the top of the threaded rod 83. The first forward gear 91 is meshed with a reverse gear 92 on the outside. A support shaft 93 is fixedly passed through the axis of the reverse gear 92, and the support shaft 93 is rotatably connected to the protective shell 77.

[0064] A second forward gear 94 is mounted on the top of the support shaft 93, and a positioning opening is provided on the support shell for the first forward gear 91 and the second forward gear 94 to pass through. A first drive plate 95 and a second drive plate 96 are respectively provided on the two housings 3 located above the high-voltage wires. The first drive plate 95 and the first forward gear 91 are in the same plane, and the second drive plate 96 and the second forward gear 94 are in the same plane.

[0065] A plurality of tooth blocks 97 meshing with the forward gears are mounted at equal distances on the side of the first drive plate 95 and the second drive plate 96 away from the housing 3 .

[0066] When the infrared camera 1 moves to the power tower, the second motor 63 runs, so that the guide wheel 62 rolls along the support plate 72, and the limiting roller 64 moves to the limiting track 73, realizing the limiting effect on the movement of the guide wheel 62. At the same time, when the guide wheel 62 moves along the uphill alignment section 74, the four shells 3 are separated from the outside of the high-voltage power line in pairs, and move synchronously with the multiple guide wheels 62. When the first shell 3 located above moves to the middle moving end, the multiple tooth blocks 97 thereon engage with the first forward gear 91, so that the first forward gear 91 drives the threaded rod 83 to rotate synchronously. When the threaded rod 83 rotates, it provides driving force for the rear plate 82, and since the rear plate 8 Under the limiting effect of the protective shell 77, the lens cleaning cotton 81 is driven to move downward along the protective shell 77. When the movement stops, the camera head of the infrared camera 1 contacts the cleaning cotton, thereby achieving the function of wiping the camera head. As the multiple guide wheels 62 continue to move, when the second housing 3 located above moves to the middle moving end, the multiple tooth blocks 97 thereon engage with the second forward gear 94, and the second forward gear 94 drives the reverse gear 92 to rotate synchronously, thereby causing the first forward gear 91 to rotate in the opposite direction to the second forward gear 94, further causing the threaded rod 83 to rotate in the opposite direction, thereby increasing the driving force of the rear plate 82, and thus retracting the cleaning cotton into the protective shell 77.
