[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention:

[0023] Please see Figure 1 and Figure 2This utility model discloses a temporary grounding device, including a planetary gear module 2, a grounding rod 1, and a grounding plate 3. The planetary gear module 2 includes a gear ring 21, a sun gear 22, a planet carrier 24, and three planet gears 23. Each planet gear 23 meshes with the sun gear 22 and the gear ring 21, respectively. The planet carrier 24 is located above the sun gear 22 and is fixedly connected to all three planet gears 23. The grounding rod 1 is vertically fixed to the bottom of the sun gear 22. Two telescopic brackets 4 are also fixedly installed at the bottom of the gear ring 21, and the two telescopic brackets 4 are evenly arranged along the gear ring 21. Each telescopic bracket 4 has a grounding claw 6 at its bottom end. The grounding plate 3 is welded and fixed to the upper part of the grounding rod 1, and a grounding hole is opened on the grounding plate 3. 31; A rotating handle 7 is fixedly installed on the top of the planetary carrier 24; the grounding rod 1 includes a round steel 11 and a drill rod 12 welded and fixed to the bottom end of the round steel 11, the round steel 11 being a galvanized steel pipe; in use, hold the rotating handle 7, place the grounding rod 1 of the temporary grounding device perpendicular to the ground, and insert the grounding claws 6 at the bottom of the two telescopic brackets 4 into the ground to provide support for the gear ring 21. Then, turn the rotating handle 7 clockwise to drive the planetary carrier 24 and planetary gears 23 to rotate. After the planetary gears rotate, they drive the sun gear 22 to rotate, thereby driving the grounding rod 1 to rotate and drill into the ground until it drills into the ground 1000mm and protrudes 200mm above the ground. Connect the grounding wire of the tool to the grounding hole 31. When the tool is removed from the site, remove the grounding wire, turn the rotating handle counterclockwise to make it automatically protrude from the ground, and continue rotating to easily rotate out the grounding rod 1.

[0024] Specifically, the aforementioned grounding plate 3 is made of galvanized flat steel, and the aforementioned telescopic bracket 4 is welded and fixed to the bottom of the toothed ring 21.

[0025] In an embodiment of this utility model, the telescopic bracket 4 has a three-section structure, including a bottom rod, a middle rod, and an upper rod. The middle rod and the upper rod are hollow. The lower rod is telescopically fitted inside the middle rod, and the middle rod is telescopically fitted inside the upper rod. Rubber washers 5 are fixedly fitted on the outer walls of the top ends of the middle rod and the lower rod. The outer diameter of the rubber washers 5 on the outer wall of the middle rod is 0.1 to 0.3 mm larger than the inner diameter of the upper rod, and the outer diameter of the rubber washers 5 on the outer wall of the lower rod is 0.1 to 0.3 mm larger than the inner diameter of the middle rod. This allows the telescopic bracket 4 to provide a certain supporting force to the planetary gear module 2, and does not affect the downward displacement of the grounding rod 1 when it is driven downward by the planetary gear module 2.

[0026] Specifically, the assembly method of the aforementioned temporary grounding device includes: purchasing a drill rod 12 (φ40, 200mm in length) and a planetary gear module 2; welding the drill rod 12 to a round steel 11 (φ40) (1000mm long) to form a grounding rod 1; welding a 100mm galvanized flat steel to the side of the round steel 11 and drilling a grounding hole 31 to form a grounding plate 3 on the upper part of the grounding rod 1; welding the sun gear 22 of the planetary gear module 2 to the top of the grounding rod 1; welding a rotating handle 7 above the planetary carrier 24 of the planetary gear module 2; welding two telescopic rods with a length of 1200mm to the corresponding sides of the gear ring 21 as telescopic supports 4; and welding ground claws 6 to the bottom of the telescopic supports 4 to complete the assembly of the temporary grounding device. The telescopic supports 4 are used to support the gear ring 21 on the one hand, and can also help improve the verticality of the grounding rod 1 after it is drilled into the ground on the other hand.

[0027] The aforementioned planetary gear module 2 is used to increase the rotational speed of the grounding rod 1; specifically, in the planetary gear module 2: the gear ring 21 has 100 teeth and a radius of 100 mm; the sun gear 22 has 26 teeth and a radius of 26 mm; and the planet gear 23 has 37 teeth and a radius of 37 mm.

[0028] This utility model discloses a temporary grounding device that utilizes a planetary gear module to accelerate the drilling of the grounding device into the ground, saving time and improving work efficiency. It also provides accurate control over the burial depth; by rotating the drill, construction personnel can easily control the burial depth, improving the compliance of construction operations. This temporary grounding device is specifically designed for metallurgical engineering construction and offers strong flexibility, readily responding to sudden emergency repair tasks. It allows construction tools and distribution boxes to be quickly grounded and put into use. The device can be used in various complex construction environments. Maintenance operations in metallurgical engineering are often conducted within steel plants, where the environment is complex and the work area is often small. Therefore, the lightweight and compact design of the grounding device is particularly important. This temporary grounding device occupies little space, requiring no external motor or other space-consuming accessories, making it highly adaptable to maintenance work. It is simple to manufacture, and the entire grounding process is convenient and quick. It does not require complicated operating procedures, which can greatly save construction preparation time, improve maintenance efficiency, have a low damage rate, low component cost, simple assembly, and can be stockpiled in batches. If it is damaged during construction, it can be directly replaced, saving time wasted on maintenance and saving later maintenance costs.
