[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0024] like Figure 1-3 As shown, an emergency short-circuit busbar device for an aluminum electrolysis terminal tank is connected to the busbar surrounding the tank of the accident aluminum electrolysis terminal tank and the adjacent workshop busbar, which can solve the problem that the traditional emergency short-circuit busbar cannot directly connect the busbar surrounding the tank with the workshop busbar.

[0025] An emergency short-circuit busbar device for an aluminum electrolysis terminal tank comprises a short-circuit busbar body and a clamping device 5; the two ends of the short-circuit busbar body are respectively crimped to a tank surrounding busbar 1 and a workshop busbar 2 of the aluminum electrolysis terminal tank, and are clamped by the clamping device 5.

[0026] The short-circuit busbar body includes a crimping block 3 and an aluminum soft strip 4. The two ends of the aluminum soft strip 4 are respectively provided with a crimping block 3, one of the crimping blocks 3 is crimped to the busbar 1 around the slot and is compressed by a clamping device 5, and the other crimping block 3 is crimped to the workshop busbar 2 and is compressed by a clamping device 5. The connection paths of the two crimping blocks 3 and the busbar 1 around the slot and the workshop busbar 2 correspond one by one to the conductive paths of the aluminum electrolytic cell.

[0027] The two crimping blocks 3 are crimped on the flat aluminum busbars on the busbars 1 around the slot and the workshop busbar 2, avoiding the aluminum plate, and the installation path is short. The short-circuit busbar is less in quantity and lighter, and is more convenient to install.

[0028] The short-circuit busbar body is provided with 7 groups, the two crimping blocks 3 of the two groups of short-circuit busbar bodies at both ends are used to crimp the upper or lower parts of the flat aluminum busbars on the busbars 1 around the grooves and the workshop busbar 2, and the two crimping blocks 3 of the three middle groups of short-circuit busbar bodies are used to crimp the sides of the flat aluminum busbars on the busbars 1 around the grooves and the workshop busbar 2.

[0031] The aluminum soft belt 4 is composed of multiple bundles of aluminum soft belts, and multiple pieces of aluminum soft belts are stacked by annealing 1 mm thick aluminum sheets. The rigidity of the aluminum soft belt 4 in the annealed state is reduced. The aluminum soft belt 4 is wavy or arc-shaped when welded, so it can play a dual adjustment role in the horizontal and vertical directions. The length can be adjusted in the vertical direction, which is convenient for on-site installation.
