[0016] Working principle: The busbar compartment 7, handcart compartment 8, and cable compartment 9 are stacked. The fixing rods 27 at the top and bottom of the handcart compartment 8 are inserted into the blind holes on the busbar compartment 7 and cable compartment 9, respectively, thereby installing the busbar compartment 7, handcart compartment 8, and cable compartment 9. Then, the first movable plate 11 and the second movable plate 12 are rotated, and the first movable plate 11 and the second movable plate 12 are fitted together. The first movable plate 11 and the second movable plate 12 are connected by the threaded rod 13, thereby connecting and installing the busbar compartment 7, handcart compartment 8, and cable compartment 9. The cable is passed through the fixing tube 18 on the rear side of the cable compartment 9. The clamping plate 24, together with the spring 25, clamps and limits the cable. The cable then passes through two adjacent elastic semicircular frames 23. The two elastic semicircular frames 23 will fit tightly against the cable surface, thereby preventing rats or snakes from entering the device. After removing the shielding plate 21, the spring 25 can be pulled. Observe the extension situation. If it is necessary to protect the busbar compartment 7, handcart compartment 8 and cable compartment 9, put the protective frame 1 on the surface of the busbar compartment 7, handcart compartment 8 and cable compartment 9 from top to bottom. The L-shaped rod 3 is located in the groove on the protective frame 1. The opening and closing of the movable door 2 is controlled by the second hinge 30. The universal wheel 6 can drive the device to move, which improves the working range of the device. If it is necessary to install multiple devices together, turn the first bolt 15. The first bolt 15 is removed from the handcart compartment 8 and the connecting plate 14, and the L-shaped rod 3, support rod 4, base plate 5 and universal wheel 6 can be moved. The T-shaped plate 16 moves in the T-shaped arc groove on the arc plate 10. If there is water accumulation indoors or outdoors, start the cylinder 17. The cylinder 17 drives the busbar compartment 7, handcart compartment 8 and cable compartment 9 to move upward, thereby moving the busbar compartment 7, handcart compartment 8 and cable compartment 9 away from the ground.
