[0040] See also Figure 1 A grounding device provided in an embodiment of the present application includes a conductive seat 10, a conductive plug 11 and a clamping assembly 12. The conductive seat 10 is provided with a slot 101, the conductive plug 11 is used to be inserted into the slot 101, and the clamping assembly 12 is provided on the conductive seat 10 and is used to clamp the conductive plug 11 to the slot 101.

[0041] See also Figure 1, the conductive seat 10 is made of a material with excellent conductivity, and is used to connect to the grounding copper busbar. Exemplarily, the conductive seat 10 is made of galvanized steel, which has low cost and good corrosion resistance. The conductive plug 11 is made of a material with excellent conductivity, and is used to connect to the grounding end of the grounding wire. Exemplarily, the conductive plug 11 is made of copper. A slot 101 is provided on the conductive seat 10 for inserting and removing the conductive plug 11. A clamping assembly 12 is also provided on the conductive seat 10. When the conductive plug 11 is inserted into the slot 101, the conductive plug 11 can be pressed into the slot 101 by the clamping assembly 12, so that the conductive plug 11 is tightly attached to the conductive seat 10 to achieve electrical connection.

[0042] When the power equipment in the power plant is shut down for maintenance, the grounding device provided in the embodiment of the present application can be used to ground the power equipment. The specific grounding process is: first, the conductive seat 10 is fixedly connected to the grounding copper bus, and the conductive plug 11 is fixedly connected to the grounding end of the grounding wire; then, the conductive plug 11 is inserted into the slot 101 of the conductive seat 10, and the conductive plug 11 is compressed by the clamping assembly 12; then, the conductor end of the grounding wire is clamped on the conductor of the power equipment using a grounding wire pliers, thereby achieving reliable grounding of the power equipment.

[0043] When the maintenance of the power equipment in the power plant is completed, the grounding clamp is first removed from the conductor of the power equipment, and then the clamping force on the conductive plug 11 is removed through the clamping component 12, and the conductive plug 11 is pulled out of the slot 101, so that the conductive plug 11 is separated from the conductive seat 10, thereby realizing the grounding of the power equipment.

[0044] Therefore, the grounding device provided in the embodiment of the present application utilizes a conductive seat 10 to connect with the grounding copper busbar, and utilizes a conductive plug 11 to connect with the grounding end of the grounding wire; when grounding, the conductive plug 11 is first inserted into the slot 101 on the conductive seat 10, and then the conductive plug 11 is compressed by the clamping assembly 12, so that the conductive plug 11 and the conductive seat 10 are reliably connected together, thereby achieving a firm and reliable connection between the grounding end of the grounding wire and the grounding copper busbar. Compared with directly fixing the grounding end of the grounding wire to the grounding copper busbar with bolts, the risk of the grounding end of the grounding wire becoming loose is reduced, and the reliability of grounding is improved.

[0045] In some embodiments, see Figure 2 , Figure 3 , Figure 4 The pressing assembly 12 includes a rotating portion 121 and a pressing portion 122 . The rotating portion 121 is rotatably mounted on the conductive seat 10 . The pressing portion 122 is transmission-connected to the rotating portion 121 and approaches or moves away from the conductive plug 11 during the rotation of the rotating portion 121 .

[0046] Exemplarily, the rotating part 121 is installed on the conductive seat 10 so that the rotating part 121 rotates around its own axis; the two ends of the rotating part 121 are respectively an operating end and a transmission end, the operating end of the rotating part 121 is arranged on the outside of the conductive seat 10, and the transmission end of the rotating part 121 is arranged on the inside of the conductive seat 10; the clamping part 122 is arranged on the inside of the conductive seat 10 and can approach or move away from the conductive plug 11 in a straight line; the transmission end of the rotating part 121 is transmission-connected to the clamping part 122 to convert the rotational motion of the rotating part 121 into the linear motion of the clamping part 122. During operation, a force is applied to the operating end of the rotating part 121 through a tool to make the rotating part 121 rotate clockwise, and the rotating part 121 drives the clamping part 122 to approach the conductive plug 11 until the conductive plug 11 is clamped; a force in the opposite direction is applied to the operating end of the rotating part 121 through a tool to make the rotating part 121 rotate counterclockwise, and the rotating part 121 drives the clamping part 122 away from the conductive plug 11 to remove the clamping force on the conductive plug 11.

[0047] In some embodiments, see Figure 2 , Figure 3 , Figure 4 , the clamping assembly 12 also includes a wrench 123 for driving the rotating part 121 to rotate. The wrench 123 applies a force to the operating end of the rotating part 121 to drive the rotating part 121 to rotate, and then the clamping part 122 applies a clamping force that meets the requirements to the conductive plug 11. In order to improve the operating efficiency, in some embodiments, the wrench 123 is a ratchet wrench. By setting a ratchet wrench, the operator can hold the ratchet wrench and use a simple swinging action to achieve the reciprocating motion of the wrench and the rotating part 121, without the need for repeated holding and adjusting the position, thereby improving the operating efficiency; and when the power equipment is grounded using the grounding device provided in the application embodiment, the unlocking paddle of the ratchet wrench can be turned to the locked position, so that the ratchet wrench cannot be operated, and it is impossible to apply a force to the rotating part 121, thereby avoiding the accidental removal of the grounding end of the grounding wire. Further, the wrench 123 is detachably connected to the rotating part 121. After the electric equipment is grounded, the wrench 123 can be removed and stored in a tool box, so that other workers cannot rotate the rotating part 121 without the wrench, thereby ensuring that the grounding end of the grounding wire is reliably grounded.

[0048] In some embodiments, see Figure 5 The conductive seat 10 includes a conductive shell 102 and a conductive block 103 connected to the conductive shell 102 . A slot 101 with two ends opened is arranged on one side of the conductive block 103 . A socket 104 is arranged on one end of the conductive shell 102 facing the slot 101 .

[0049] Exemplarily, the conductive shell 102 is a cubic structure surrounded by multiple galvanized steel plates, and the adjacent galvanized steel plates can be connected by welding or bolts; the conductive block 103 is made of galvanized steel plates and fixed in the conductive shell 102; a slot 101 with two ends opened and for the conductive plug 11 to be inserted is provided on one side of the conductive block 103, and a socket 104 is provided on the conductive shell 102 for the conductive plug 11 to be inserted therein. During operation, the conductive plug 11 is inserted into the slot 101 through the socket 104, and then the conductive plug 11 is pressed into the slot 101 by the pressing assembly 12.

[0050] The conductive base 10 can be connected to the grounding copper bar by welding. Figure 2 , Figure 3 , Figure 4 The conductive seat 10 further includes a conductive ear plate 105, which is connected to the conductive housing 102. Exemplarily, the conductive ear plate 105 is made of galvanized steel plate, and includes two conductive ear plates 105, which are arranged on both sides of the conductive housing 102, and the conductive ear plates 105 are connected to the conductive housing 102 by welding. When the conductive seat 10 is connected to the grounding copper busbar, the conductive ear plate 105 and the grounding copper busbar can be attached and the two can be connected by welding or bolts.

[0051] The conductive plug 11 can be connected to the grounding end of the grounding wire by welding. Exemplarily, the grounding end of the grounding point is connected with a copper nose, and the copper nose is fixedly connected to the conductive plug 11 by bolts.

[0052] In some embodiments, see Figure 1 , Figure 3 The conductive housing 102 is provided with an observation window 106. By providing the observation window 106, the fitting and pressing conditions of the conductive plug 11 in the slot 101 can be observed to ensure the reliability of grounding.

[0053] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiments shall still fall within the protection scope of the technical solution of the present application.
