It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0051] Refer to Figures 1 - 19 As shown, the present utility model is a grounding device, including an embedding member 1. One end of the embedding member 1 is connected to one end of a grounding cable 2. The lower end of the embedding member 1 is inserted into the soil. The other end of the grounding cable 2 is connected to a grounding device through a connecting cable 4. The middle part of the grounding cable 2 is wound around a wire take-up assembly 3. The wire take-up assembly includes a support frame 301. The support frame 301 is fixedly connected to a fixing frame 302. The fixing frame 302 is fixedly connected to one end of a connecting pipe 304. A plurality of bearings 30602 are sleeved on the connecting pipe 304. The outer ring of the bearing 30602 is fixedly connected to a rotating pipe 306. The end of the rotating pipe 306 is fixedly connected to an end plate 305. A plurality of support rods 307 are arranged between the two end plates 305. The end of the support rod 307 is fixedly connected to the end plate 305. The support rods 307 are arranged in a circular array on the end plate 305. A clamping member 308 is arranged at the middle part of the outer wall of the rotating pipe 306. The middle part of the grounding cable 2 is arranged in the clamping member 308.

[0052] The present utility model provides an embodiment. Refer to Figures 4 - 9, the clamping member 308 includes two fixed ring plates 30801 arranged in parallel. The fixed ring plates 30801 are fixedly connected to the rotating tube 306, and at least two winding rods 30802 are arranged between the two fixed ring plates 30801. When the grounding cable 2 is arranged in the clamping member 308 and the grounding cable 2 is wound around the take-up assembly 3, the connecting member 204 at one end of the grounding cable 2 is passed through between the winding rods 30802 between the nine o'clock position and the twelve o'clock position, and passes out through the winding rod 30802 at the nine o'clock position, and finally passes out between the two support rods 307. The connecting member 206 at the other end of the grounding cable 2 is passed through between the winding rods 30802 between the twelve o'clock position and the three o'clock position, and passes out through the winding rod 30802 at the three o'clock position, and finally passes out between the two support rods 307. Then, the connecting member 204 and the connecting member 206 are pulled out, so that the cable 201 is tightened between the winding rod 30802 at the nine o'clock position, the winding rod 30802 at the twelve o'clock position, and the winding rod 30802 at the three o'clock position. Then, the end plate 305 is rotated by the rotating handle 309, and the rotating tube 306 is driven by the end plate 305 to rotate on the bearing 30602 of the connecting tube 304, so that the grounding cable 2 is wound around the outside of the support rod 307. The winding method is to wind from the middle part of the support rod 307 to both ends. After one layer is fully wound, then wind from both ends of the support rod 307 to the middle part of the support rod 307. The cable 201 from the middle part to the connecting member 204 is the first winding section, and the cable 201 from the middle part to the connecting member 206 is the second winding section. The first winding section and the second winding section of the grounding cable 2 are respectively wound on both sides of the support rod 307. These two sides are the parts extending from the clamping member 308 to both ends, so that the first winding section and the second winding section do not interfere with each other.

[0053] Another embodiment is provided by the present utility model. Refer to Figures 10 - 13, the clamping member 308 includes a fixed ring plate 30801, a moving member 30803 is sleeved on the rotating tube 306, at least two winding rods 30802 are fixed at the end of the fixed ring plate 30801, a first communication hole 308033 is provided on the moving member 30803, and the winding rod 30802 is inserted into the first communication hole 308033. When the grounding cable 2 is arranged in the clamping member 308, when the grounding cable 2 is wound around the cable take-up assembly 3, the connecting member 204 and the connecting member 206 at the end of the grounding cable 2 are passed through between the winding rods 30802 between the nine o'clock position and the twelve o'clock position. The connecting member 204 passes through the winding rod 30802 at the nine o'clock position and finally passes through between the two support rods 307. The connecting member 206 passes through the winding rod 30802 at the twelve o'clock position and finally passes through between the two support rods 307. Then, the connecting member 204 and the connecting member 206 are pulled out, so that the cable 201 is tightened between the winding rod 30802 at the nine o'clock position and the winding rod 30802 at the twelve o'clock position. Then, by adjusting the position of the nut on the adjusting bolt 30804, the distance between the moving member 30803 and the fixed ring plate 30801 is reduced, and the length of the winding rod 30802 on the fixed ring plate 30801 inserted into the first communication hole 308033 is increased, so that the moving member 30803 and the fixed ring plate 30801 clamp the cable 201 therein, preventing the cable 201 from moving in the clamping member 308. After that, the end plate 305 is rotated by the rotating handle 309, and the rotating tube 306 is driven by the end plate 305 to rotate on the bearing 30602 of the connecting tube 304, so that the grounding cable 2 is wound around the outside of the support rod 307. The winding method is to wind from the middle part of the support rod 307 to both ends. After one layer is fully wound, then wind from both ends of the support rod 307 to the middle part of the support rod 307. The cable 201 from the middle part to the connecting member 204 is the first winding section, and the cable 201 from the middle part to the connecting member 206 is the second winding section. The first winding section and the second winding section of the grounding cable 2 are respectively wound on both sides of the support rod 307. These two sides are the parts extending from the clamping member 308 to both ends, so that the first winding section and the second winding section do not interfere with each other.

[0054] In use, connect the first connector 204 of the grounding cable 2 to the embedding part 1. The first connection hole of the first connector 204 at the end of the grounding cable 2 is concentric with the fourth connection hole on the embedding part 1. The first connection hole and the fourth connection hole are fixed together by bolts. Then, release the grounding cable 2 from the support rod 307 through the wire take-up assembly 3, so that the connection cable 4 on the second connector 206 at the other end of the grounding cable 2 can be connected to the electrical equipment. It is not necessary to fully release the grounding cable 2, and fix the third connector 404 at the end of the connection cable 4 to the metal shell of the electrical equipment, thus completing the grounding. After use or testing, separate the third connector 404 of the connection cable 4 from the metal shell of the electrical equipment, then rotate the end plate 305 and the rotating tube 306 by turning the rotating handle 309, and then retract the grounding cable 2 onto the support rod 307, waiting for the next use.
