As shown in fig. 1, the camera 1 is an explosion-proof camera in the prior art and is fixed on the inner wall of the coal mine. A plurality of cameras in the same region are in a group, and a cleaning unit is arranged among the plurality of cameras in the group. The bracket 2 is fixed on the inner wall of the coal mine, as shown in fig. 2, the bracket 2 is of an 'u-shape' structure, and angle steel can be selected. When the cameras are installed, the cameras arranged in groups are positioned on the same straight line as much as possible. A pair of lower guide rails 3 are fixed on the top of the bracket, the cross section of each lower guide rail is rectangular, as shown in fig. 3, a limiting groove 31 is arranged on the side wall of each lower guide rail, and the limiting groove on one lower guide rail is positioned on the side surface far away from the other lower guide rail. A pair of racks 32 is fixed at the top of the bracket between the two lower guide rails, an upper guide rail 33 is arranged above the bracket, the cross section of the upper guide rail is circular, and a plurality of support rods 34 are arranged between the upper guide rail and the bracket to realize the fixation between the upper guide rail and the bracket.
The bracket is provided with a walking frame 4, as shown in fig. 4, the walking frame is in a horizontal structure, a pair of left and right limiting strips 41 are arranged on the inner wall of the walking frame, and the limiting strips extend into the limiting grooves to realize the relative fixation between the walking frame and the lower guide rail in the vertical direction. The inner side of the walking frame is connected with the top of the lower guide rail in a sliding mode, a walking motor 42 and a pair of ear plates 44 are arranged at the bottom of the walking frame, a wheel shaft is arranged between the two ear plates, walking wheels 43 are fixed at two ends of the wheel shaft and are in contact with the racks, teeth are arranged on the outer walls of the walking wheels, and then the walking wheels are meshed with the racks. Under the drive of the walking motor, the walking wheels rotate, and then the whole walking frame is driven to move along the lower guide rail.
