[0088] In the embodiment of the present application, the bottom plate 102, the first baffle 1031 and the second baffle 1032 of the base 101 cooperate with the upper horizontal cover plate 201 to form an installation space for cables to pass through, and a manual switch structure is provided in the connection structure between the upper horizontal cover plate 201 and the base 101 to facilitate the opening and closing of the installation space, thereby enabling the upper horizontal cover plate 201 to be quickly disassembled and assembled.

[0089] On the basis that the upper horizontal cover plate 201 can be quickly disassembled and assembled, the embodiment of the present application is convenient for installation, maintenance and replacement of cables, and because the cables are operated on the basis of the upper horizontal cover plate 201 being opened, unlike the prior art which requires cutting the cables, in the embodiment of the present application, there is no need to damage the cables, so no secondary damage to the cables will occur during the maintenance process, thereby reducing maintenance costs.

[0090] In addition, the base 101 of the embodiment of the present application can adopt an integrated structure, and maintenance and assembly do not require disassembly, which can reduce damage and manpower.

[0091] An automatic reset twisted structure can be adopted between the first end of the upper horizontal cover plate 201 and the first baffle 1031 in the embodiment of the present application. When the upper horizontal cover plate 201 is opened, it can rotate around the automatic reset twisted axis 202 and the maximum rotation angle can reach more than 180°, which can reduce disassembly and assembly wear.

[0092] The embodiment of the present application can set fixed wires on the bottom surface of the bottom plate 102 and bundle the cables into bundles through the fixed wires, which can well fix the cables and prevent the cables from being offset during the movement of the tank chain; it can further set fixed wire grooves at the bottom of the bottom plate of the unit structure at certain intervals, and finally further increase the fixation of the cables. Compared with the use of cable ties in the prior art, the fixed wires can use flexible binding ropes without causing damage to the cables.
