[0047] See also Figures 1 to 5 A conductive structure for grounding provided in an embodiment of the present application includes a conductive seat 10 and a clamping assembly 12. 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 provided on one side of the conductive block 103. A socket 104 is provided on the end of the conductive shell 102 facing the slot 101. The clamping assembly 12 is provided on the conductive shell 102 and is used to clamp the conductive plug 11 to the slot 101.

[0048] See also Figure 1 The conductive seat 10 is made of a material with good electrical conductivity and is used to connect to the grounding copper bar. For example, the conductive seat 10 is made of galvanized steel, which has low cost and good corrosion resistance. Figure 2 , Figure 3 , Figure 4 , Figure 5 The conductive base 10 includes a conductive shell 102 for connecting to the grounding copper bar and a conductive block 103 connected to the conductive shell 102. The conductive shell 102 is a cubic structure surrounded by multiple galvanized steel plates. Adjacent galvanized steel plates can be connected by welding or bolts. The conductive block 103 can be made of galvanized steel plates, and one side of the conductive block 103 is provided with a slot 101 with two ends opened for the conductive plug 11 to be inserted. The conductive shell 102 is provided with a socket 104 so that the conductive plug 11 can be inserted into the slot 101 through the socket 104. The pressing component 12 is provided on the conductive shell 102. When the conductive plug 11 is inserted into the slot 101, the pressing component 12 can be used to press the conductive plug 11 into the slot 101, so that the conductive plug 11 and the conductive base 10 are closely attached to achieve electrical connection.

[0049] When the power equipment in the power plant is shut down for maintenance, the conductive structure for grounding provided in the embodiment of the present application can be used to ground the power equipment. The specific grounding process is as follows: Figure 7 , Figure 8 , Fig. 9First, the conductive shell 102 of the conductive seat 10 is fixedly connected to the grounding copper busbar, 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 on the conductive block 103 through the socket 104 on the conductive shell 102, and the conductive plug 11 is pressed into the slot 101 by the pressing component 12; then the conductor end of the grounding wire is clamped on the conductor of the power equipment with a grounding wire pliers, thereby realizing reliable grounding of the power equipment.

[0050] 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.

[0051] Therefore, the conductive structure provided in the embodiment of the present application utilizes the conductive shell 102 of the conductive seat 10 to connect with the grounding copper busbar. When grounding, the conductive plug 11 connected to the grounding end of the grounding wire is first inserted into the slot 101 on the conductive block 103 through the socket 104 on the conductive shell 102, and then the conductive plug 11 is pressed 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.

[0052] The conductive housing 102 can be connected to the grounding copper bar by welding. Figures 1 to 4 , a conductive ear plate 105 is connected to the conductive housing 102. Exemplarily, the conductive ear plate 105 is made of galvanized steel plate, and the conductive ear plate 105 includes two conductive ear plates 105, which are arranged on both sides of the conductive housing 102, and the conductive ear plate 105 is connected to the conductive housing 102 by welding. When the conductive seat 10 is connected to the grounding copper bar, the conductive ear plate 105 and the grounding copper bar can be attached and the two can be welded or bolted.

[0053] In some embodiments, see Figures 1 to 5 , a locking indexing pin 13 is provided on the conductive housing 102, and the pin head of the locking indexing pin 13 is provided in the conductive housing 102 and is used to lock with the conductive plug 11 under the action of a spring. Exemplarily, the locking indexing pin 13 is vertically arranged and movably connected to the conductive housing 102, so that the locking indexing pin 13 can move along its own axis, and a spring is connected between the locking indexing pin 13 and the conductive housing 102, and the spring provides a reset force to move the pin head of the locking indexing pin 13 toward the conductive plug 11; the conductive plug 11 is provided with a locking groove that matches the pin head of the locking indexing pin 13. See Fig. 9When the conductive plug 11 is inserted into the slot 101, the pin head of the locking indexing pin 13 is inserted into the locking groove under the operation of the spring to lock the conductive plug 11, prevent the conductive plug 11 from being accidentally pulled out, and improve the reliability of grounding; when unlocking is required, just pull the locking indexing pin 13 upward to separate the pin head of the locking indexing pin 13 from the locking groove.

[0054] In some embodiments, participating Figures 1 to 5 The conductive housing 102 is provided with an electromagnetic lock 14, and the lock head of the electromagnetic lock 14 is used to lock and cooperate with the conductive plug 11. The conductive plug 11 is provided with a locking groove that cooperates with the lock head of the electromagnetic lock 14. Fig. 9 When the conductive plug 11 is inserted into the slot 101, the lock head of the electromagnetic lock 14 extends out and is inserted into the locking groove to lock the conductive plug 11, thereby preventing the conductive plug 11 from being pulled out by mistake and improving the reliability of grounding. When unlocking is required, the lock head of the electromagnetic lock 14 only needs to be retracted to separate the lock head of the electromagnetic lock 14 from the locking groove.

[0055] In some embodiments, see Figure 6 , an insulating housing 15 is connected to one side of the conductive housing 102, and a battery connected to the electromagnetic lock 14 is disposed in the insulating housing 15. The battery is provided to power the electromagnetic lock 14, and the battery is provided in the insulating housing 15, thereby improving the safety of the battery when in use. In other embodiments, a controller for controlling the operation of the electromagnetic lock 14 may also be provided in the insulating housing 15.

[0056] In some embodiments, see Figure 1 , Figure 3 , Figure 6 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.

[0057] In some embodiments, see Figure 2 , Figure 3 , Figure 4 The clamping assembly 12 includes a rotating portion 121 and a clamping portion 122. The rotating portion 121 is rotatably mounted on the conductive housing 102. The clamping portion 122 is transmission-connected to the rotating portion 121 and approaches or moves away from the slot 101 during the rotation of the rotating portion 121.

[0058] Exemplarily, the rotating part 121 is installed on the conductive shell 102 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 shell 102, and the transmission end of the rotating part 121 is arranged on the inside of the conductive shell 102; the clamping part 122 is arranged on the inside of the conductive shell 102 and can approach or move away from the slot 101 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, after the conductive plug 11 is inserted into the slot 101, 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.

[0059] 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, 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.

[0060] 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.
