[0040] See also Figure 1 The conductive seat 10 is made of a material with good conductivity and is used to connect to the grounding copper bar. Figure 1 The structure of the grounding copper busbar is not shown. Exemplarily, the conductive seat 10 is made of galvanized steel, which has low cost and good corrosion resistance. The conductive seat 10 is provided with a slot 101 for inserting and removing the conductive plug 11. The conductive plug 11 is made of a material with excellent conductivity and is connected to the grounding end of the grounding wire 17. Exemplarily, the conductive plug 11 is made of copper, and the grounding end of the grounding wire 17 is connected to a copper nose, which is connected to the conductive plug 11 by a bolt. The clamping assembly 12 is provided on the conductive seat 10, and is used to clamp the conductive plug 11 inserted in the slot 101 so that the conductive plug 11 is tightly attached to the conductive seat 10 to achieve electrical connection.

[0041] See also Figure 5, the smart electromagnetic lock 14 is arranged in the conductive seat 10, and has two states: open and locked. When the smart electromagnetic lock 14 is in the open state, the conductive plug 11 can be inserted into the slot 101 or pulled out from the slot 101; when the smart electromagnetic lock 14 is in the locked state, it can not only prevent the conductive plug 11 outside the slot 101 from being inserted into the slot 101, but also lock the conductive plug 11 pre-inserted into the slot 101 to prevent the conductive plug 11 from being pulled out by mistake. Exemplarily, a locking groove that matches the lock head of the smart electromagnetic lock 14 is provided on the conductive plug 11; when the conductive plug 11 is inserted into the slot 101, the lock head of the smart electromagnetic lock 14 extends and then inserts into the locking groove, so that the smart electromagnetic lock 14 is in the locked state to lock the conductive plug 11; the lock head of the smart electromagnetic lock 14 is retracted and separated from the locking groove, so that the smart electromagnetic lock 14 is in the open state to unlock the conductive plug 11.

[0042] See also Figure 1 , the smart key 16 is a key used to open the smart electromagnetic lock 14. Specifically, when the smart key 16 approaches the smart electromagnetic lock 14, the smart electromagnetic lock 14 identifies the identity information of the smart key 16 correctly and issues an opening command, thereby putting the smart electromagnetic lock 14 in an open state; when the smart key 16 is away from the smart electromagnetic lock 14, the smart electromagnetic lock 14 is in a locked state after a delay of a period of time. The smart key 16 is set at the conductor end of the ground wire 17. Exemplarily, the conductor end of the ground wire 17 is connected to a ground wire clamp, and the smart key 16 is fixed to the ground wire clamp.

[0043] When the power equipment in the power plant is shut down for maintenance, the intelligent grounding device provided in the embodiment of the present application can be used to ground the power equipment. The method of grounding the power equipment using the intelligent grounding device provided in the embodiment of the present application includes the following steps:

[0044] S1, the conductive base 10 is fixedly connected to the grounding copper bar. In this step, the intelligent electromagnetic lock 14 in the conductive base 10 is always in a locked state, so that the conductive plug 11 cannot be inserted into the slot 101 of the conductive base 10.

[0045] S2, bring the smart key 16 at the conductor end of the ground wire 17 close to the smart electromagnetic lock 14 in the conductive seat 10 to open the smart electromagnetic lock 14. In this step, when the smart key 16 is close to the smart electromagnetic lock 14, the smart electromagnetic lock 14 identifies the identity information of the smart key 16 correctly and issues an opening command, thereby putting the smart electromagnetic lock 14 in an open state, and at this time, the conductive plug 11 can be inserted into the slot 101 of the conductive seat 10.

[0046] S3, insert the conductive plug 11 of the grounding end of the grounding wire 17 into the slot 101 on the conductive seat 10, compress the conductive plug 11 by the compressing component 12, and lock the conductive plug 11 by the intelligent electromagnetic lock 14. In this step, the conductive plug 11 is compressed by the compressing component 12 to ensure that the conductive plug 11 is in close contact with the conductive seat 10; the conductive plug 11 is locked by the intelligent electromagnetic lock 14 to prevent the conductive plug 11 from being pulled out by mistake.

[0047] S4, connecting the conductor end of the grounding wire 17 to the conductor of the power equipment. In this step, the conductor end of the grounding wire 17 is clamped on the conductor of the power equipment by a grounding clamp, thereby achieving grounding of the power equipment.

[0048] When the power equipment in the power plant is overhauled, it needs to be ungrounded. The specific process is: first remove the conductor end of the grounding wire 17 from the conductor of the power equipment, move the smart key 16 at the conductor end of the grounding wire 17 close to the smart electromagnetic lock 14 in the conductive seat 10 to open the smart electromagnetic lock 14, then remove the clamping force on the conductive plug 11 through the clamping component 12, and then pull the conductive plug 11 out of the slot 101 to separate the conductive plug 11 from the conductive seat 10, thereby achieving ungrounding of the power equipment.

[0049] The intelligent grounding device provided in the embodiment of the present application has the intelligent key 16 arranged at the conductor end of the grounding wire 17, and the intelligent key 16 can open the intelligent electromagnetic lock 14 only when it is close to the intelligent electromagnetic lock 14 paired with it. Therefore, when installing and removing the grounding wire 17, the grounding wire 17 can only be installed in a manner of first installing the grounding end of the grounding wire 17 and then installing the conductor end of the grounding wire 17, or the grounding wire 17 can only be removed in a manner of first removing the conductor end of the grounding wire 17 and then removing the grounding end of the grounding wire 17, so as to avoid the situation of first installing the conductor end and then installing the grounding end, or first removing the grounding end and then removing the conductor end, so as to regulate the safe use and installation and removal of the grounding wire 17 from the perspective of technical measures.

[0050] The intelligent grounding device provided in the embodiment of the present application utilizes a conductive base 10 to connect with a grounding copper busbar during grounding. The conductive plug 11 is inserted into the slot 101 of the conductive base 10, the conductive plug 11 is compressed by a compression assembly 12, and the conductive plug 11 is locked by an intelligent electromagnetic lock 14, so as to achieve a firm and reliable connection between the grounding end of the grounding wire 17 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 being loosened or removed by mistake is reduced, thereby improving the reliability of grounding.

[0051] In some embodiments, the smart key 16 includes an NFC key; the smart electromagnetic lock 14 includes an electromagnetic lock body, and a battery and an electric control system connected to the electromagnetic lock body; wherein the battery is used to power the electromagnetic lock body, and the electric control system includes an NFC chip module, which is used to issue an opening command after the identity information of the smart key 16 is recognized to be correct, thereby retracting the lock head of the electromagnetic lock body to put the smart electromagnetic lock 14 in an open state. In order to improve security, see Figure 1 , Figure 2 , Figure 3 , Figure 4 One side of the conductive base 10 is connected to an insulating shell 15 , and the battery and the electric control system of the smart electromagnetic lock 14 are arranged in the insulating shell 15 .

[0052] In some embodiments, see Figures 1 to 5 , a spring indexing pin 13 for locking with the conductive plug 11 is provided on the conductive seat 10. Exemplarily, a locking groove that matches the pin head of the spring indexing pin 13 is provided on the conductive plug 11, and one end of the conductive plug 11 for inserting into the slot 101 is an arc-shaped structure. In the process of inserting the conductive plug 11 into the slot 101, the conductive plug 11 contacts the pin head and drives the pin head to retract. When the pin head of the spring indexing pin 13 is aligned with the locking groove, the pin head extends under the action of the spring and is inserted into the locking groove to lock the conductive plug 11, and then the conductive plug 11 is positioned so that the lock head of the smart electromagnetic lock 14 is facing the locking groove, which is convenient for the subsequent locking of the conductive plug 11 by the smart electromagnetic lock 14. When it is necessary to release the locking of the conductive plug 11 by the spring indexing pin 13, it is only necessary to pull the spring indexing pin 13 upward to retract the pin head until it is separated from the locking groove.

[0053] 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 .

[0054] 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.

[0055] 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 is used to apply 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 intelligent 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.

[0056] 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 .

[0057] 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.

[0058] 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.

[0059] 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 position, fit and compression of the conductive plug 11 in the slot 101 can be observed to ensure the reliability of grounding.

[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.
