Description

Technical Field

[0001] This application relates to the field of inspection equipment, and particularly to a mobile inspection device for cable trenches and cable tunnels. Background Art

[0002] In urban construction, some communication cables and power transmission cables are arranged in tunnels at a specific depth underground. These underground cables need to be maintained regularly, and some even need to be inspected multiple times a day to ensure their safety and normal operation. The existing inspection and maintenance work all requires manual operation with detection equipment for inspection. This manual inspection method is not only limited to larger cable tunnels that people can enter, increasing the construction cost of cable tunnels, but also has a slow inspection efficiency. With the development of technology, operators can remotely control the detection equipment to move in the cable tunnel for automatic inspection. However, this inspection method has certain limitations. First, when the depth of the cable is relatively large, the mobile inspection device sometimes cannot receive the control signal from the operator, that is, it is affected by the depth of the tunnel from the ground and the length of the tunnel. Second, the cost of the inspection device is high and it is not economically practical. Content of the Utility Model

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that an article or terminal device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such article or terminal device.

[0019] In urban construction, a part of the cables for communication and the power cables for power transmission are arranged in tunnels at a specific depth underground. These underground cables and power cables need to be maintained regularly, and some even need to be inspected multiple times a day to ensure the safety of the cables and power cables and guarantee normal operation. All the existing inspection and maintenance work requires manual inspection with detection equipment. This manual inspection method is not only limited to the larger cable tunnels that people can enter, increasing the construction cost of the cable tunnels, but also the inspection efficiency is slow. With the development of technology, operators use remote control detection equipment to move in the cable tunnel to achieve automatic inspection. However, this inspection method has certain limitations. First, when the depth of the cable is relatively large, the mobile inspection device sometimes cannot receive the control signal from the operator, that is, it is affected by the depth of the tunnel from the ground and the length of the tunnel. Second, the cost of the inspection device is high and it is not economically practical.

[0020] Therefore, the embodiment of the present utility model provides a mobile inspection device for cable trenches and cable tunnels, which solves the problems of the limitations of the existing inspection equipment and the high cost of the inspection device.
