[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A substation busbar bridge grounding device includes a busbar bridge 1, terminals 2, and a conductive plate 5. Terminals 2 are installed at the lower middle end of the busbar bridge 1, and a conductive plate 5 is fixedly connected to the middle of the terminals 2. A segmented protective shell 3 is installed on the outer side of the middle of the terminals 2. A connector 6 is connected to the middle of the terminals 2 through a gasket 8 and a fixing bolt 9. A grounding wire 4 is fixedly connected to the lower end of the connector 6. Clamping mechanisms 7 are installed on both sides of the conductive plate 5. The clamping mechanism 7 includes a bent rod 71, the upper end of which is rotatably connected to the conductive plate 5 through a rotating shaft 73. An inclined block 72 is installed on one side of the top end of the bent rod 71, and an arc-shaped plate 74 is fixedly connected to one side of the bottom end of the bent rod 71. A protrusion 75 is fixedly connected inside the arc-shaped plate 74. The gasket 8 includes a ring plate 81, and a central hole 82 and a slot 83 are opened on the inner side of the ring plate 81.

[0029] As a further implementation of this solution, the terminal 2 is U-shaped, and the segmented protective shell 3 is divided into two sections. The two segments of the segmented protective shell 3 are connected by a sealing ring and a snap fastener. The terminal 2 is fixedly connected to one of the segmented protective shells 3. Through the above settings, the sealing effect at the connection between the terminal 2 and the grounding wire can be improved.

[0030] As a further implementation of this solution, two clamping mechanisms 7 are provided, which are arranged on both sides of the connector 6. Through the above arrangement, the lower end of the connector 6 can be stably limited.

[0031] As a further implementation of this solution, the bent rod 71 is L-shaped, the vertical section of the arc plate 74 is C-shaped, and the arc plate 74 has multiple protrusions 75 for fixed connection inside. Through the above settings, the stability of the arc plate 74 and the lower end of the connector 6 can be further improved.

[0032] As a further implementation of this solution, the inclined block 72 is set at the upper end of the bent rod 71 near the connector 6, and the arc plate 74 is in close contact with the lower end of the connector 6 through the protrusion 75. With the above arrangement, the bent rod 71 can be controlled to rotate by the inclined block 72 during the movement of the shim 8.

[0033] As a further implementation of this solution, the intermediate hole 82 is a through hole, which is connected to the slot 83. The vertical cross-section of the intermediate hole 82 is T-shaped. Through the above settings, the stability of the connection between the connector 6 and the conductive plate 5 can be further improved.

[0034] As a further implementation of this solution, a round hole is provided on the inner side of the upper end of the connector 6, and the fixing bolt 9 is set inside the connector 6 and the gasket 8.

[0035] Workflow: During the installation of the substation busbar bridge grounding device, the workers first open the segmented protective shell 3. After opening, the connector 6 is fixed using the gasket 8 and fixing bolts 9. During the fixing process, the fixing bolts 9 pass through the gasket 8 and connector 6 and are spirally connected to the conductive plate 5 to fix the connector 6. During the fixing process, the slot 83 positions the lower end of the connector 6, effectively preventing the gasket 8 from rotating during the fixing process. Furthermore, during the fixing process, the gasket 8 continuously moves towards the conductive plate 5. During the movement of the shim 8, the inclined block 72 is squeezed. During the squeezing process, the bent rod 71 rotates around the pivot 73. During the rotation of the pivot 73, the arc plate 74 fixedly connected to the bottom of the bent rod 71 will automatically press against the lower end of the connector 6. Through the relative movement of the two arc plates 74, the lower end of the connector 6 is clamped. After the fixing bolt 9 is tightened, the two arc plates 74 fix the lower end of the connector 6. After the fixation is completed, the other segmented protective shell 3 is connected to the segmented protective shell 3 fixedly connected to the terminal 2 to complete the installation.
