[0029] Reference Figures 1-5This is the first embodiment of the present invention, which proposes a grounding structure for a high-voltage disconnecting switch, including a base plate 1, a support plate 2 on the top of the base plate 1, a protective component 3 on the top of the support plate 2, the protective component 3 including a terminal 31, one end of the terminal 31 being located on the top of the support plate 2, a rotating rod 32 being rotatably connected to the side of the support plate 2, a protective cover 33 being fixedly connected to the circumferential surface of the rotating rod 32, a gear 34 being fixedly connected to one end of the rotating rod 32, a mounting plate 5 being fixedly connected to the side of the support plate 2, a cylindrical rod 35 being fixedly connected to the side of the mounting plate 5, a diagonal rod 36 being fixedly connected to the end of the cylindrical rod 35 away from the mounting plate 5, an electric telescopic rod 37 being fixedly connected to the side of the diagonal rod 36, an L-shaped rod 38 being fixedly connected to the circumferential surface of the cylindrical rod 35, a long plate 39 being fixedly connected to the bottom of the L-shaped rod 38, a rack 310 being slidably connected to the bottom of the long plate 39, and an electric telescopic rod 37 being fixedly connected to one end of the rack 310 at the end away from the diagonal rod 36.

[0030] The rack 310 and gear 34 mesh with each other, the terminal 31 is located on the displacement trajectory of the protective cover 33, the top of the mounting plate 5 is provided with a mounting groove, and the side of the protective cover 33 is provided with a slot 48. The design of the mounting plate 5 allows the entire grounding device to be installed in the required location.

[0031] There are two mounting plates 5, which are symmetrical to each other along the vertical central axis of the rotating rod 32. There are two wiring terminals 31, which are arranged in a linear array on the top of the support plate 2. The two mounting plates 5 can be used for stable installation.

[0032] Two L-shaped rods 38, cylindrical rods 35, gears 34, electric telescopic rods 37, and diagonal rods 36 are provided and are symmetrical to each other along the vertical central axis of the protective cover 33. The two electric telescopic rods 37 can operate simultaneously from both ends to help the protective cover 33 move stably.

[0033] In this embodiment, when the grounding structure is not in use, the telescopic end of the electric telescopic rod 37 can be extended, which will drive the rack 310 to move, allowing the rack 310 to slide along the long plate 39 and move away from the inclined rod 36. The movement of the rack 310 will drive the gear 34 to rotate clockwise, which will drive the rotating rod 32 to rotate clockwise, and the clockwise rotation of the rotating rod 32 will drive the protective cover 33 to rotate towards the top of the grounding structure, covering the connecting wire 311, the wire connector 31 and other structures for protection. When the protective cover 33 is not needed for protection, the telescopic end of the electric telescopic rod 37 is retracted, the rack 310 moves towards the side close to the inclined rod 36, the rack 310 drives the gear 34 to reverse, the rotating rod 32 reverses, and the protective cover 33 rotates away from the top of the grounding structure. The electric telescopic rod 37 can automatically extend and retract, triggering the rotation of the protective cover 33, thereby automatically covering the key components such as the wire connector 31 when needed, providing protection. This automatic mechanism reduces the need for human intervention, improving the safety and convenience of operation. When the protective cover 33 is covered, it can effectively isolate external factors (such as dust, moisture, collision, etc.) from affecting the grounding structure, ensuring that the grounding structure is not damaged and reducing equipment failure or performance degradation caused by environmental factors. By regularly protecting and automatically closing the protective cover 33, the device can be protected from external environmental influences, prolonging the service life of the grounding structure and preventing corrosion or other damage caused by long-term exposure to the external environment.
