Description

Movable ground stake

Technical field:

The utility model relates to a movable ground pile.

Background technique:

In recent years, with the intensification of substation construction and technical transformation of substation equipment, the replacement of equipment in substations is increasing. When replacing switches with grounding switches or performing maintenance work on grounding switches, maintenance equipment needs to be installed Temporary ground wires ensure the personal safety of maintenance personnel during work. However, at present, the workload of adding grounding piles to the grounding switch in the substation is very large, the implementation period is long, and a large amount of fixed grounding pile materials are required. Therefore, it is necessary to design a movable grounding pile to ensure temporary grounding. When the line is installed, it can be reliably grounded.

Invention content:

In order to overcome the defects of the prior art, the purpose of this utility model is to provide a movable grounding pile, which can ensure reliable grounding when the temporary grounding wire is installed. It can also meet the requirements of the State Grid Corporation of China to prevent electrical misoperation, and can be included in the substation microcomputer anti-misoperation locking management. It solves the problem of large workload and large amount of grounding piles for welding fixed grounding piles in order to install temporary grounding wires for reliable grounding at the substation site, and reduces labor intensity. On the other hand, the layout of on-site safety measures is flexible, reducing on-site safety risks and improving on-site safety management.

The utility model solves the technical problem and adopts the following technical solutions:

Movable grounding pile, the body of the grounding pile is in the shape of an inverted F, and a clamping bolt is threaded on the middle platform of the grounding pile, and the bottom end of the clamping bolt is fixedly connected with a clamping plate. The pressing plate and the bottom platform of the grounding pile form a wire clip; the grounding pile body above the intermediate platform is provided with a grounding terminal jack.

A U-shaped groove is arranged on the bottom platform of the ground pile.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

1. The ground pile of the utility model is convenient and flexible to install, can be reliably installed on the ground flat iron or round steel at the maintenance site, and is firmly connected with the ground grid.

2. After the grounding pile of the utility model is put into use, it will be incorporated into the microcomputer five-proof locking management process, and the logic of the original microcomputer five-proof locking will not be changed.

3. The grounding pile of the utility model eliminates the need to add a large number of fixed grounding piles to be welded in the substation, which not only reduces a lot of workload, but also saves the materials for fixing the grounding pile.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Labels in the figure: 1 grounding pile body, 2 clamping bolts, 3 clamping plate, 4 grounding terminal jack, 5 bottom platform, 6 U-shaped groove, 7 middle platform, 8 hexagonal wrench.

The utility model will be further described below through specific embodiments in conjunction with the accompanying drawings.

Detailed ways:

Embodiment: In combination with Fig. 1, the movable grounding pile of this embodiment, the grounding pile body 1 is in an inverted F shape, and the clamping bolt 2 is threaded on the middle platform 7, and the bottom end of the clamping bolt 2 is fixedly connected with a The clamping plate 3 is used to form a line clamp by clamping the platen 3 and the bottom platform 5 of the grounding pile; the grounding terminal jack 4 is provided on the grounding pile body 1 above the intermediate platform. A U-shaped groove 6 is arranged on the bottom platform 5 of the ground pile.

When in use, clamp the clamp between the bottom platform 5 of the ground pile and the clamping plate 3 on the grounded flat iron or grounded round steel, and use the hex wrench 8 to pull the clamping bolt 2 to make the clamping plate 3 Move and fix the grounding pile firmly on the grounding flat iron or grounding round steel, take out the inner hexagonal wrench 8, pass the grounding side of the temporary grounding wire through the grounding terminal jack 4 and fix it, and then hang a five-proof locking padlock. At this time, the inner hexagonal wrench 8 cannot be inserted into the clamping bolt 2 because of the installation of the grounding side of the grounding wire, so as to ensure the reliable fixing of the mobile grounding pile.
