Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1 - Figure 7 As shown, the present invention is a temporary grounding device for power engineering construction operations, including a metal frame 1, and further including: a winding part 2, which is disposed on the metal frame 1; a storage part 3, which is disposed on the left side of the metal frame 1; and a replacement part 4, which is disposed on the metal frame 1. The winding section 2 includes a winding assembly 21, which is mounted on a metal frame 1; and a limiting assembly 22, which is mounted on the winding assembly 21. The winding assembly 21 includes a metal shaft 211 rotatably connected to the metal frame 1, a cable reel 212 fixedly connected to the outer wall of the metal shaft 211, a limiting gear 214 fixedly connected to the outer wall of the metal shaft 211, a rectangular plate 215 fixedly connected to the right side of the metal frame 1, and a slide rod assembly 216 slidably connected to the rectangular plate 215. A limiting block 217 is fixedly connected to the bottom end of the metal frame 1. The limiting block 217 meshes with the limiting gear 214. A rotating component is provided on the metal shaft 211. The right end of the metal shaft 211 passes through the metal frame 1. The rotating component includes a crank 213 fixedly connected to the metal shaft 211. The crank 213 is located on the right side of the metal frame 1. The limiting assembly 22 includes two limiting holes 221 opened on the right side of the metal frame 1. A knob screw 222 is threadedly connected to the limiting block 217. The left end of the knob screw 222 extends to the opposite side. Inside the corresponding limiting hole 221, the outer wall of the knob screw 222 is rotatably connected to the corresponding limiting hole 221. After the wire clamp rod 313 is fixed in place, rotate the crank 213 on the right side of the metal frame 1. The crank 213 drives the metal shaft 211 to rotate synchronously. When the metal shaft 211 rotates, it drives the cable reel 212 on the outer wall to rotate, and the grounding wire is wound up onto the cable reel 212 in an orderly manner. After the grounding wire is wound up, the knob screw 222 on the limiting block 217 can be unscrewed to release the limitation on the limiting block 217. Under the guidance of the rectangular plate 215 and the slide bar assembly 216, the limiting block 217 is pushed to move towards the metal shaft 211 until the limiting gear 214 at the bottom of the limiting block 217 meshes with the limiting gear 214 on the outer wall of the metal shaft 211, locking the metal shaft 211 to prevent accidental rotation. Finally, the knob screw 222 is tightened inward so that its left end is inserted into the corresponding limiting hole 221 on the right side of the metal frame 1, thus completing the limiting and fixing of the limiting block 217 and preventing the grounding wire from coming loose in the storage state.

[0018] The storage unit 3 includes a rectangular block 311 fixedly connected to the left side of the metal frame 1. A fixing groove 312 is provided on the top of the rectangular block 311. A wire clamp rod 313 is slidably connected within the fixing groove 312. A fixing block 314 is disposed within the fixing groove 312. The outer wall of the wire clamp rod 313 contacts the fixing block 314 and the fixing groove 312. A second knob screw 315 is threaded onto the rectangular block 311. The right end of the second knob screw 315 is rotatably connected to the fixing block 314. A guide is provided on the rectangular block 311. The end of the cable reel 212 is fixedly connected to the wire clamp rod 313. The guide includes components slidably connected to the rectangular block 311. The two guide rods 316 on the 11 are fixedly connected to the fixing block 314 at their right ends. When storing, the wire clamp rod 313 fixed at the end of the cable roll 212 can be inserted into the fixing groove 312 at the top of the rectangular block 311 to complete the initial positioning. Then, the knob screw 315 is rotated. The knob screw 315 will rotate inward along the rectangular block 311, pushing the fixing block 314 to move in the fixing groove 312. With the guidance and limiting of the two guide rods 316, the fixing block 314 squeezes the wire clamp rod 313 to fix the wire clamp rod 313 and prevent it from loosening and falling off during storage.

[0019] The replacement unit 4 includes a replacement assembly 41, which is mounted on the metal frame 1; and a connecting assembly 42, which is mounted on the replacement assembly 41. The replacement assembly 41 includes a replacement slot 411 formed at the top of the metal frame 1. A plurality of telescopic rods 412 are fixedly connected to the inner wall of the replacement slot 411. Two clamping blocks 413 are fixedly connected to one end of each telescopic rod 412 that is close to each other. A grounding post 414 is provided on one side of each clamping block 413 that is close to each other. The outer wall of the frame 12 is wound with springs 415. One end of each spring 415 is fixedly connected to a replacement slot 411, and the other end of each spring 415 is fixedly connected to two clamping blocks 413. The connecting assembly 42 includes a metal block 421 set on the top of the metal frame 1. A groove 422 is opened on the top of the metal block 421. A screw 423 is slidably connected in the groove 422. The bottom end of the screw 423 is fixedly connected to the metal frame 1. A knob 424 is threadedly connected to the outer wall of the screw 423. The bottom of knob 424 contacts metal block 421, and the outer wall of grounding stake 414 contacts metal block 421. When the grounding device needs to be replaced or disassembled, knob 424 on top screw 423 of metal block 421 can be unscrewed first to release the limiting constraint on metal block 421. Then, slide metal block 421 outward along the groove 422 on metal block 421 to disconnect the contact connection between metal block 421 and grounding stake 414. This avoids interfering with the disassembly of grounding stake 414 during replacement and ensures safety. The operation is safe. Next, pull out the grounding stake 414. When the grounding stake 414 is pulled out, the adaptive clamping force is buffered by the two clamping blocks 413, the telescopic rod 412 and the spring 415. Under the reset action of the spring 415, the clamping block 413 moves in a guide position against the telescopic rod 412. It can adaptively adapt to the pulling force of the grounding stake 414 and easily pull the grounding stake 414 out of the replacement slot 411, realizing the quick disassembly or replacement of the grounding stake without complicated tools, which greatly improves the efficiency of on-site operation.

[0020] When storing, first insert the cable clamp rod 313 fixed at the end of the cable roll 212 into the fixing groove 312 at the top of the rectangular block 311 to complete the initial positioning. Then, turn the knob screw 315. The knob screw 315 will rotate inward along the rectangular block 311, pushing the fixing block 314 to move in the fixing groove 312. With the guidance and limiting of the two guide rods 316, the fixing block 314 will press the cable clamp rod 313 to fix the cable clamp rod 313 and prevent it from loosening and falling off during storage. After the wire clamp rod 313 is fixed in place, rotate the crank 213 on the right side of the metal frame 1. The crank 213 drives the metal shaft 211 to rotate synchronously. When the metal shaft 211 rotates, it drives the cable reel 212 on the outer wall to rotate, and the grounding wire is wound onto the cable reel 212 in an orderly manner. After the grounding wire is wound up, the knob screw 222 on the limit block 217 can be turned outward to release the limiting constraint on the limit block 217. At this time, the rectangular plate 215 and the slide rod assembly 21 With the guidance of 6, the limiting block 217 is pushed to move towards the metal shaft 211 until the limiting gear 214 at the bottom of the limiting block 217 meshes with the limiting gear 214 on the outer wall of the metal shaft 211, locking the metal shaft 211 to prevent accidental rotation. Finally, the knob screw 222 is screwed inward to insert its left end into the corresponding limiting hole 221 on the right side of the metal frame 1, thus completing the limiting and fixing of the limiting block 217 and preventing the grounding wire from coming loose in the storage state. When the grounding device needs to be replaced or disassembled, the knob 424 on the top screw 423 of the metal block 421 can be unscrewed first to release the limiting constraint on the metal block 421. Then, the metal block 421 can be slid outward along the sliding groove 422 on the metal block 421 to disconnect the contact connection between the metal block 421 and the grounding stake 414. This avoids interfering with the disassembly of the grounding stake 414 during the replacement process and ensures operational safety. Next, the grounding stake 414 can be pulled outward. When the grounding stake 414 is pulled out, the adaptive clamping force is buffered by the two clamping blocks 413, the telescopic rod 412 and the spring 415. Under the reset action of the spring 415, the clamping blocks 413 are aligned with the telescopic rod 412 and moved in a guiding manner. This can adaptively adapt to the pulling force of the grounding stake 414 and easily pull the grounding stake 414 out of the replacement slot 411, realizing the quick disassembly or replacement of the grounding stake without complicated tools, which greatly improves the efficiency of on-site operations.
