Abstract

The utility model relates to a retractable ground flat steel connecting device, including run -on, spring, copper ring and flexible coupling line, the run -on sets up both ends, the one end of run -on is passed through the bolt and is connected with ground flat steel, the other end of run -on respectively through the spring with the copper ring links to each other, the run -on with be provided with the flexible coupling line between the copper ring, the utility model discloses a retractable ground flat steel connecting device when the both ends grounding band steel because of subsiding or certain external force factor when leading to the dislocation tensile, the spring can keep the flexonics, reduces the destruction that external force caused to ground flat steel, through flexible coupling line and copper ring formation ground loop, reduce contact resistance, ensure that ground resistance keeps at reliable within range.

Description

A kind of extension type grounding flat steel attachment means
Technical field
This utility model is related to a kind of grounding flat steel attachment means, more particularly to a kind of extension type grounding flat steel connection dress Put.
Background technology
As the surface subsidence of coastal area power plant is more serious, ground connection facility can the stress stretching or curved because of surface subsidence Song, serious meeting cause grounding flat steel to be broken, and extensively adopt is welded and fixed existing grounding flat steel connected mode more, and coastal region Power plant can cause there is displacement difference between different structures because of sedimentation, which results in the grounding flat steel stress for rigidly fixing and become Shape, seriously can then break, and earth resistance can increase even up to infinitely great, and protective grounding can be ineffective, and personal safety can be received To threat, while this electrical equipment high to lightning protection facility and grounding requirement also brings great potential safety hazard.
In view of above-mentioned defect, the positive in addition research and innovation of the design people is flat to founding a kind of extension type ground connection Steel attachment means so as to more the value in industry.
Utility model content
For solve above-mentioned technical problem, even if the purpose of this utility model be to provide one kind two-terminal-grounding band steel because sedimentation or When certain external force factor causes dislocation stretching, still keep earth resistance invariable, improve stretching for earthed system reliability Contracting formula grounding flat steel attachment means.
A kind of extension type grounding flat steel attachment means of the present utility model, including connection row, spring, copper ring and are flexible coupling Line, the connection row arrange two ends, and one end of the connection row is connected with grounding flat steel by bolt, the connection row other end It is connected with the copper ring by spring respectively, between the connection row and the copper ring, is provided with flexible connecting line.
Further, the length of the flexible connecting line is 1.2-2 times of the spring length of run.
Further, the copper ring is positioned at the centre position of two line rows
By such scheme, this utility model at least has advantages below:1st, when two-terminal-grounding band steel because sedimentation or certain When external force factor causes dislocation stretching, spring can keep flexible connection, reduce the destruction that external force is caused to grounding flat steel;2nd, lead to Cross flexible connecting line and earth-return circuit is formed with copper ring, reduce contact resistance, it is ensured that earth resistance is maintained in confidence band.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model Art handss end, and being practiced according to the content of description, with preferred embodiment of the present utility model and coordinates accompanying drawing detailed below Describe in detail bright as after.
Description of the drawings
Fig. 1 is a kind of structural representation of extension type grounding flat steel attachment means of this utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
Embodiment 1
Referring to Fig. 1, a kind of extension type grounding flat steel attachment means described in one preferred embodiment of this utility model include Connection row 1, spring 2, copper ring 3 and flexible connecting line 4, connection row 1 are arranged on two ends, and one end of connection row 1 passes through bolt and ground connection Band steel connects, and the other end of connection row 1 is connected with the copper ring 3 of centre by spring 2 respectively, arranges between connection row 1 and copper ring 3 The length for having flexible connecting line 4, flexible connecting line has certain surplus, is 1.2-2 times of spring length of run.
When the connection row 1 that grounding flat steel is located is affected to produce displacement stretching by surface subsidence, band steel is kept by spring 2 Stress equalization, the flexible connecting line 4 of 3 both sides of copper ring keep enough length surpluses, are not forced, this ensures that there two-terminal-grounding Band steel will not cause earth resistance to become big because of external force so that ground connection is relatively reliable.
The settlement of foundation of Wu Sha mountains Power Plant Buildings thing is affected by various factors, and annual settling amount does not all know, around structure The grounding flat steel for building thing has the situation for being pulled off displacement every year, and the earth resistance local ground is unqualified, by installing The ground connecting device, it is ensured that the earth resistance of whole earth mat is balanced, it is to avoid Yin Jiyin sedimentations and cause earth mat to destroy, pole Big improves Earthing Reliability.
The above is only preferred implementation of the present utility model, is not limited to this utility model, it is noted that For those skilled in the art, on the premise of without departing from this utility model know-why, can also do Go out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
