The underground water seepage can be effectively prevented when the underground station power equipment grounding, the signal equipment grounding and the lightning protection grounding are connected with the comprehensive grounding network, and the protection requirement of fault current (stray current) can be well met.

The ground lead-out wire of the subway ground lead-out device produced by all factories is fixed in length, local lines in a subway station are shorter, local lines are longer, the length of the ground lead-out wire of the existing subway ground lead-out device cannot be adjusted, and the applicability is poor.

Disclosure of Invention

The present utility model is directed to a novel grounding device, which solves the problem that the length of the grounding lead-out wire cannot be adjusted by the grounding lead-out device proposed in the background art.

In order to solve the technical problems, the utility model provides the following technical scheme:

the novel grounding device comprises a protection cylinder, wherein a first grounding lead wire of a cylindrical structure is arranged in the protection cylinder, a threaded groove is formed in the top of the first grounding lead wire, a second grounding lead wire of the cylindrical structure is connected in the threaded groove in a threaded manner, and an external thread structure is arranged on the outer wall of the second grounding lead wire.

Further, a water stop ring is arranged in the middle of the outer part of the protection cylinder.

Further, an insulating filler is filled between the inner wall of the protection cylinder and the outer wall of the grounding outgoing line.

Further, the diameter of the first grounding lead wire is larger than that of the second grounding lead wire.

Furthermore, the lower end of the first grounding lead wire and the upper end of the second grounding lead wire are respectively provided with a connecting hole.

Further, the first grounding lead wire and the second grounding lead wire are copper columns

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the second grounding outgoing line is rotated to enable the second grounding outgoing line to ascend or descend, so that the length of the second grounding outgoing line is changed according to the reserved length of the circuit, the applicability is better, and the installation and the use are more convenient.

Detailed Description

For the purpose of further illustrating the various embodiments, the present utility model provides the accompanying drawings, which are a part of the disclosure of the present utility model, and which are mainly used to illustrate the embodiments and, together with the description, serve to explain the principles of the embodiments, and with reference to these descriptions, one skilled in the art will recognize other possible implementations and advantages of the present utility model, wherein elements are not drawn to scale, and like reference numerals are generally used to designate like elements.

According to an embodiment of the present utility model, a novel grounding device is provided.

Embodiment one:

as shown in fig. 1-2, the novel grounding device comprises a protection cylinder 1, wherein a first grounding lead wire 2 with a cylindrical structure is arranged in the protection cylinder 1, a thread groove 3 is formed at the top of the first grounding lead wire 2, a second grounding lead wire 4 with the cylindrical structure is connected in the thread groove 3 in a threaded manner, and an external thread structure is arranged on the outer wall of the second grounding lead wire 4;

embodiment two:

a water stop ring 5 is arranged in the middle outside the protection cylinder 1;

insulating filler is filled between the inner wall of the protection cylinder 1 and the outer wall of the grounding lead-out wire I2;

the diameter of the first grounding lead wire 2 is larger than that of the second grounding lead wire 4;

the lower end of the first grounding lead wire 2 and the upper end of the second grounding lead wire 4 are respectively provided with a connecting hole 6, and the connecting holes 6 are used for connecting circuits;

the first grounding lead-out wire 2 and the second grounding lead-out wire 4 are copper columns;

the working principle of the utility model is as follows:

when the line reservation is longer, the second grounding lead wire 4 is rotated anticlockwise, so that the second grounding lead wire 4 descends, and the length of the second grounding lead wire 4 is shortened to adapt to the longer line;

when the line reservation is shorter, the second grounding lead wire 4 is rotated clockwise to enable the second grounding lead wire 4 to rise, so that the length of the second grounding lead wire 4 is increased to adapt to the longer line

Therefore, the second grounding lead wire 4 is rotated to enable the second grounding lead wire 4 to ascend or descend, so that the length of the second grounding lead wire 4 is changed according to the reserved length of the circuit, the applicability is better, and the installation and the use are more convenient.
