[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] As Figure 1 and 2As shown in the figure, in this embodiment, a percussion grounding device is disclosed, which includes a percussion grounding rod 1, an interlocking rod unlocking and locking device 2, an energy storage device 3, and a grounding clamp 4.

[0031] The percussion grounding rod 1 includes a grounding rod insulating housing 101. The rear end of the grounding rod insulating housing 101 is a closed structure, and the front end is an open structure. A percussion interlocking rod 102 and a percussion spring 103 are arranged in the grounding rod insulating housing 101. The rear end of the percussion interlocking rod 102 abuts against the percussion spring 103. The front end of the percussion interlocking rod 102 is provided with a claw seat 104. A plurality of claws 105 are arranged in a circular shape at the top of the claw seat 104, and each claw 105 is rotatably connected to the claw seat 104.

[0032] The interlocking rod unlocking and locking device 2 is arranged in the grounding rod insulating housing 101, and the interlocking rod unlocking and locking device 2 locks or unlocks the percussion interlocking rod 102.

[0033] The energy storage device 3 is arranged on the grounding rod insulating housing 101, and the energy storage device 3 is used to drive the percussion interlocking rod 102 to move backward to compress the percussion spring 103.

[0034] The grounding clamp 4 includes an upper clamping plate 401 and a lower clamping plate 402. One end of the upper clamping plate 401 is provided with a clamping plate arm 403. The clamping plate arm 403 is connected to the grounding wire. A support arm 404 is arranged on the clamping plate arm 403. A guide sleeve 405 is fixed on the support arm 404. A grounding clamp connecting rod 406 is arranged in the guide sleeve 405. The front end of the grounding clamp connecting rod 406 is fixed to the lower clamping plate 402, and the rear end is provided with a grasping head 407 that cooperates with the claw 105. A clamping plate spring 408 is sleeved on the grounding clamp connecting rod 406. One end of the clamping plate spring 408 abuts against the lower clamping plate 402, and the other end abuts against the support arm 404.

[0035] Before use, the claw seat 104 is threadedly connected to the front end of the percussion interlocking rod 102. The claws 105 on the claw seat 104 are all movable. As the energy storage device 3 drives the percussion interlocking rod 102 to move backward to compress the percussion spring 103, when the percussion interlocking rod 102 retracts into the grounding rod insulating housing 101, the claws 105 are restricted and contracted by the grounding rod insulating housing 101 to tightly grasp the grasping head 407. At the same time, by means of the front end of the grounding rod insulating housing 101 abutting against the guide sleeve 405, the claws 105 pull the grounding clamp connecting rod 406 to move backward, so that the upper clamping plate 401 and the lower clamping plate 402 are separated (at this time, the clamping plate spring 408 is compressed). After the lower clamping plate 402 moves in place, the percussion interlocking rod 102 is locked and fixed under the action of the interlocking rod unlocking and locking device 2.

[0036] When it is necessary to ground the high-voltage line, the locking rod is controlled to release the locking device 2 to unlock and release the firing interlock rod 102. The firing interlock rod 102 is reset under the action of the firing spring 103, and at the same time, the hook claw 105 and the gripping head 407 are pushed to move outward, and finally the hook claw 105 releases the grounding clamp link 406. The clamp link 406 is reset under the action of the clamp spring 408, driving the lower clamp plate 40 and the upper clamp plate 401 to cooperate to close and clamp the grounding flat iron or drainage line.

[0037] like Figure 2 As shown, in this embodiment, a guide slide hole 403-1 is provided on the clamp arm 403, a screw rod 404-1 is fixed on the support arm 404, the screw rod 404-1 is slidably matched with the guide slide hole 403-1, a locking nut 409 is threadedly connected to the screw rod 404-1, and the locking nut 409 cooperates with the support arm 404 to clamp the clamp arm 403 in the middle. After the locking nut 409 is loosened, the support arm 404 moves up and down along the guide slide hole 403-1, thereby adjusting the deformation of the clamp spring 408, changing the clamping strength of the upper and lower clamps, and can be conveniently and firmly connected and fixed with the equipment grounding flat iron or drainage line.

[0038] like Figure 3 As shown, in this embodiment, a plurality of limit teeth 5 are provided on the outer wall of the firing interlock rod 102 along the length direction, and the limit teeth 5 are inverted teeth from front to back on the firing interlock rod 102. The interlock rod unlocking device 2 is engaged with the limit teeth 5, and the interlock rod unlocking device 2 locks or unlocks the firing interlock rod 102 by engaging the limit teeth 5. The energy storage device 3 is pressed against the limit teeth 5. The energy storage device 3 drives the firing interlock rod 102 to move backward by pressing against the limit teeth 5.

[0039] like Figure 4 and 5 As shown, in this embodiment, the interlocking rod unlocking device 2 includes an unlocking rod 201, and a card hole 202 is provided on the outer wall of the unlocking rod 201 for facilitating the passage of the firing interlocking rod 102, and the card hole 202 is engaged with the limiting tooth 5. The unlocking rod 201 is provided with an unlocking spring 203 at one end on the same side as the limiting tooth 5, and one end of the unlocking spring 203 is against the inner wall of the insulating shell 101 of the grounding rod, and the other end is sleeved on the positioning column 204, and the unlocking spring 203 is against the unlocking rod 201, and the diameter of the unlocking rod 201 is larger than the positioning column 204, and the positioning column 204 is fixed on the unlocking rod 201, and the unlocking rod 201 is provided with a pressing head 205 at the end away from the limiting tooth 5, and an unlocking opening 206 that cooperates with the pressing head 205 and the positioning column 204 is opened on the shell wall of the insulating shell 101 of the grounding rod. The aperture of the unlocking opening 206 that cooperates with the pressing head 205 is larger than the aperture of the unlocking opening 206 that cooperates with the positioning column 204 .

[0040] When the interlocking rod unlocking device 2 is used, the pressing head 205 is pressed inward to drive the locking hole 202 to disengage from the limiting tooth 5, thereby unlocking the lock. When the pressing head 205 is released, the unlocking rod 201 is reset under the action of the unlocking spring 203, so that the locking hole 202 continues to be locked with the limiting tooth 5. When the firing interlocking rod 102 moves backward, since the limiting tooth 5 is in an inverted tooth shape, the locking hole 202 is automatically locked with the limiting tooth 5 without controlling the interlocking rod unlocking device 2.

[0041] like Figures 6 to 8 As shown, in this embodiment, the energy storage device 3 includes a trigger fixing frame 301 fixed on the ground rod insulating housing 101, and the trigger fixing frame 301 is provided with two ear side plates 302 on one side close to the ground rod insulating housing 101, and a trigger 303 is provided between the two ear side plates 302, and the trigger 303 is rotatably connected to the ear side plates 302 on both sides through a trigger shaft 304, and a first torsion spring 305 is installed on the trigger shaft 304, and one end of the first torsion spring 305 is against the trigger fixing frame 301, and the other end is against the trigger 303;

[0042] A grip 306 is fixed on the trigger 303 on the side away from the first torsion spring 305, and the grip 306 is pressed and limited with the trigger fixing frame 301; a torsion spring support rod 307 is arranged on the trigger 303 on the side facing the first torsion spring 305, and a second torsion spring 308 is installed on the torsion spring support rod 307, one end of the second torsion spring 308 is pressed against the trigger 303, and the other end is pressed against the toothed paddle 309, and the toothed paddle 309 is rotatably connected to the trigger 303 through the paddle shaft 310, and the toothed paddle 309 is pressed against the back of the trigger 303. A trigger opening 311 is opened on the shell wall of the ground rod insulating shell 101 to match the guide of the toothed paddle 309, and the toothed paddle 309 passes through the trigger opening 311 and is pressed and matched with the limiting tooth 5.

[0043] When the energy storage device 3 is in use, the grip 306 is pressed down to drive the trigger 303 to move. When the grip 306 is released, the first torsion spring 305 provides elastic force to return the trigger 303 and the trigger grip 306 to their original positions. After the grip 306 returns to its original position, it will abut against the trigger fixing frame 301. During the downward movement of the trigger 303, the toothed paddle 309 will be driven to abut against the limit tooth 5, and the limit tooth 5 will be used to push the entire firing interlock rod 102 to move backward.

[0044] After the trigger 303 is reset, the gear dial 309 returns to its normal position while avoiding the limit tooth 5 under the action of the second torsion spring 308. Specifically, after the gear dial 309 passes over the limit tooth 5, the position of the interlocking lever 102 is fixed by the interlocking lever unlocking device 2. During the reset process of the trigger 303, the trigger 303 and the trigger grip 306 return to their original positions by means of the elastic force provided by the first torsion spring 305. During this process, the gear dial 309 will touch the limit tooth 5 on the next interlocking lever 102. Under the action of the limit tooth 5, the gear dial 309 returns to its normal position while avoiding the limit tooth 5 through the action of the second torsion spring 308, waiting to continue to move the next limit tooth.

[0045] The purpose of the present utility model is to solve a series of problems that endanger the personal safety of maintenance personnel, such as when operating a traditional flat-mouth grounding wire, it is necessary to manually operate the bottom knob of the insulating rod to fix the upper and lower clamping plates of the grounding clamp to fasten the grounding flat iron or the drainage wire. It is easy to occur that due to the manual operation not in place, the upper and lower clamping plates of the grounding clamp do not firmly hold the grounding flat iron or the drainage wire and fall off, etc. It can greatly reduce the work safety risk.

[0046] Through research and practical application on-site, the present utility model solves the problem that the upper and lower clamping plates of the grounding clamp of the traditional flat-mouth grounding wire are not firmly closed due to manual operation, and it is easy to occur that the upper and lower clamping plates of the grounding clamp do not firmly hold the grounding flat iron or the drainage wire and fall off, ensuring the safety of work, equipment and personnel. It has extremely high economic and safety benefits and has great practical significance on-site. The technical effects achieved by this invention and the advantages are as follows: It is convenient to use, reduces the labor intensity of installing the grounding wire, effectively increases the fastening force of the upper and lower clamping plates of the grounding clamp, prevents the grounding clamp from loosening or even falling off due to the upper and lower clamping plates of the grounding clamp not being firmly closed by manual operation and the pulling during work, and guarantees the personal safety of maintenance personnel.

[0047] The embodiments described above are only used to describe the preferred mode of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
