Description

Technical Field

[0001] The utility model relates to the technical field of inspection robots, in particular to a distribution network visual inspection device. Background Art

[0002] A distribution network refers to an electric power grid that receives electric energy from a transmission network or a regional power plant and distributes it locally or step by step according to voltage to various users through distribution facilities. It is composed of overhead lines, cables, poles, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid.

[0003] Distribution network cable corridors are typically located underground, making them concealed projects. Conventional inspection methods rely on manual inspections using panels. This approach is labor-intensive and has a limited inspection scope, focusing only on monitoring the operation around the work pits. Inspections of cable trenches in intermediate sections of the road are difficult, and some roads are covered with municipal slabs above the cable corridors, further complicating inspections and troubleshooting.

[0004] Except for cable shafts, manual inspections are unable to detect conditions within the cable tunnels between these shafts. Any abnormalities in the cable tunnels or cables can lead to adverse consequences. However, with the development of intelligent inspection robots, they can replace manual inspections within cable tunnels. Their use in cable tunnels will become a growing trend.

[0005] Among them, when the inspection robot is normally used to inspect the cables in the cable channel, it is also necessary to set a rotatable camera on the robot to ensure that the operator can use the display screen on the remote terminal to observe and check the operation of the cable. When the inspection robot walks in the channel, the stains in the channel will infect the camera, resulting in unclear camera images. Utility Model Content

The lower part of the glass cover 106 is provided at the top. The top cover 107 is provided at the top of the top box 103, and a brush is provided in the top cover 107. A pipe 108 is connected between the top cover 107 and the liquid chamber 102. The cleaning component is provided in the inspection chamber 101, and is used to move the glass cover body 106 upward to the top cover 107 and rotate the glass cover body 106. The conveying component is provided between the top box 103 and the liquid chamber 102, and is used to convey the liquid in the liquid chamber 102 to the top cover 107. The conveying component can convey the liquid to the top cover 107 when the glass cover body 106 moves upward to a preset position.

[0032] By setting up the robot 100, the robot 100 is placed in the cable channel when in use, and the robot 100 and the camera mechanism 105 are connected to the operator's control terminal.

After cleaning is completed, the glass cover 106 is reset, and the cleaned part of the glass cover 106 corresponds to the camera again, ensuring the clarity of the camera shooting. Compared with the existing technology, the present application can solve the problem that when the inspection robot 100 walks in the channel, the stains in the channel will infect the camera, resulting in unclear camera images.

[0033] As a further feature of the present invention, the conveying component includes a liquid inlet pipe 200 connected to the top box 103, the top of the liquid inlet pipe 200 extends to the top of the top box 103, the bottom of the liquid inlet pipe 200 extends into the liquid chamber 102 and is connected to a pressure plate 201, the liquid inlet pipe 200 passes through the pressure plate 201, a plug 202 is provided on the top of the liquid inlet pipe 200, a connecting plate 203 is provided on the outside of the liquid inlet pipe 200, and a first spring 204 is connected between the connecting plate 203 and the top box 103.
