Embodiment approach

[0030] Further, as a specific embodiment of the rail-mounted inspection device for tunnels provided by the present invention, the cameras include a first camera, a second camera, a third camera and a fourth camera, and each camera is equipped with an illumination device. A lamp, the first camera, the second camera, the third camera and the fourth camera are connected with the controller. The first camera, the second camera, the third camera and the fourth camera can be respectively set to shoot in upward, downward, forward and backward directions. When the probe rod 2 is horizontal and the camera is working, the upward and downward cameras can shoot the cables above and below at the same time, enabling the device to obtain more image information in one walking; forward and backward are relative to the walking direction of the device Yes, the forward and backward cameras can record whether there are foreign objects on the walking path of the device, which will cause damage to t...

Abstract

The invention provides a track-type inspection device for a tunnel, relating to the technical field of power cable inspection. The track-type inspection device comprises a rail, a device main body hanging under the rail and walking along the rail, a horizontally arranged probe with one end connected to the device, a camera disposed at an open end of the probe, and a controller connected to the camera. In the track-type inspection device for a tunnel provided by the invention, the camera can capture details of the cable from a position directly above the cable to find out the problem and checkerroneous ideas at the outset.

Description

technical field [0001] The invention belongs to the technical field of power cable inspection, and more particularly relates to a rail-mounted inspection device for tunnels. Background technique [0002] In the cable tunnel, a large number of cables can be laid in a centralized manner by using the cable brackets arranged in the tunnel, and the inside of the tunnel is wide, which is convenient for the inspection and maintenance of the cables. The space in the cable tunnel is relatively closed, and there are certain risk factors. Therefore, there are some inspection devices in the prior art, which replace the manual inspection of the situation in the cable tunnel. The inspection device in the prior art generally senses the situation in the cable tunnel through various sensors arranged on the device, and takes pictures of the cable tunnel through the camera arranged on the device, but the camera cannot be due to the limitation of the camera angle. Detail of the cable sitting o...
