The cover plate 21 is rotatably connected to the rear side of the top of the shell 2. The cover plate 21 can completely cover the upper opening of the shell 2 to prevent fallen leaves and the like from falling into the shell 2. Four fixing columns 3 are welded and fixed on the top of the base 1 at intervals. A placement plate 31 is slidably provided on the four fixing columns 3. An electrical box 32 is placed on the placement plate 31. Clamping assemblies for clamping and fixing the electrical box 32 are provided on the left and right sides of the top of the placement plate 31. It also includes a lifting assembly and a conductive assembly. A lifting assembly for driving the placement plate 31 to move up and down is provided on the base 1. A conductive assembly for directing static electricity to the ground is provided on the base 1 and the clamping assembly.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the clamping assembly includes a fixed seat 41, a clamping plate 42 and a locking screw 43. The fixed seat 41 is symmetrically welded and fixed on the top of the placement plate 31. The clamping plate 42 is slidably connected to the upper part of the fixed seat 41. The locking screw 43 is threadedly connected to the middle of the upper part of the fixed seat 41. One end of the locking screw 43 is embedded and rotatably connected to the middle part of the clamping plate 42.

[0022] like Figure 2 and Figure 3As shown, the lifting assembly includes a motor 51, a fixing block 52 and a screw rod 53. The motor 51 is installed in the middle of the rear side of the base 1, and the fixing block 52 is welded and fixed to the rear side of the upper inner wall of the shell 2. A screw rod 53 is arranged between the fixing block 52 and the end of the output shaft of the motor 51. One end of the screw rod 53 is rotatably connected to the fixing block 52, and the other end is fixedly connected to the end of the output shaft of the motor 51 through a coupling. The screw rod 53 passes through the placement plate 31, and the intersection of the two is matched by a thread.

[0023] like Figure 3 and Figure 4 As shown, the conductive assembly includes a U-shaped conductive rod 61, a conductive wire 62, a wire buckle 63, a conductive column 64, a connecting plate 65 and a reset spring 66. The U-shaped conductive rod 61 is symmetrically connected to the left and right sides of the base 1. The lower part of the U-shaped conductive rod 61 can be inserted into the ground. The top of the U-shaped conductive rod 61 is welded and fixed with the conductive wire 62. The wire buckle 63 is symmetrically welded and fixed to the upper side of the inner wall of the shell 2. The wire buckle 63 can fix the middle part of the adjacent conductive wire 62. When one end of the conductive wire 62 moves up and down following the connecting plate 65, it can The middle part of the conductive wire 62 is limited to prevent the conductive wire 62 from being too long and becoming messy. Four conductive columns 64 are slidably connected to the clamp plate 42. A connecting plate 65 is welded and fixed between the ends of the conductive columns 64 close to the adjacent fixing seats 41. Four reset springs 66 are connected between the connecting plate 65 and the adjacent clamp plate 42, and the reset springs 66 are respectively sleeved on the outside of the conductive column 64. One end of the conductive wire 62 is fixedly connected to the adjacent connecting plate 65. The conductive column 64, the connecting plate 65, the conductive wire 62 and the U-shaped conductive rod are electrically connected in sequence.

[0024] When using this embodiment, the staff flips the cover 21 open and starts the motor 51. The motor 51 drives the placement plate 31 to move upward to the upper opening of the housing 2 through the screw rod 53, and the motor 51 is turned off. At this time, the electrical box 32 can be placed on the placement plate 31, and then the two locking screws 43 are rotated to make the two clamping plates 42 approach each other to clamp and fix the electrical box 32. In the process of the two clamping plates 42 approaching each other, the end of the conductive column 64 first contacts the electrical box 32. When the clamping plate 42 fits the surface of the electrical box 32, the conductive column 64 pushes the connecting plate 65 to move away from the adjacent clamping plate 42, thereby stretching the reset spring 66. Under the reset action of the reset spring 66, the conductive column 64 maintains the surface of the electrical box 32 The motor 51 is in a close-fitting state. At this time, the motor 51 can be started again. The motor 51 drives the screw rod 53 to reverse, so that the placement plate 31 moves downward and resets, and the electrical box 32 also follows the placement plate 31 into the shell 2. The static electricity generated on the electrical box 32 is introduced into the earth through the conductive column 64, the connecting plate 65, the conductive wire 62 and the U-shaped conductive rod 61 to be eliminated. Since the U-shaped conductive rod 61 is inside the shell 2 and inserted into the earth, it will not be damaged by external human factors. When the electrical box 32 needs to be inspected and repaired, it only needs to start the motor 51, and the electrical box 32 is lifted to the top of the shell 2 through the cooperation of the screw rod 53 and the placement plate 31. At this time, the four sides of the electrical box 32 are all in the external space, which is convenient for the staff to inspect and repair.

[0025] like Figure 3 As shown, a circular protrusion 7 is also included. The lower part of the U-shaped conductive rod 61 is provided with a circular protrusion 7. The circular protrusion 7 can increase the contact area between the U-shaped conductive rod 61 and the ground, thereby enhancing the conductive effect.

[0026] like Figure 4 The device further includes a rubber pad 8, and the side walls of the two clamping plates 42 close to each other are fixedly connected with the rubber pad 8. The rubber pad 8 can buffer the clamping force between the clamping plates 42 and the electrical box 32 to prevent the clamping plates 42 from leaving marks on the surface of the electrical box 32.
