Abstract
The utility model relates to a low-resistance grounding device, which comprises a poleshank, a module body and a fastener, wherein the module is of the tubular structure; the surface of the outer wall of the tip of the poleshank is provided with screw thread; the surface of the inner wall of the fastener is provided with screw thread and is connected with the tip of the poleshank by screw thread; the poleshank is inserted into the module body; and the module body and the poleshank are fixed into one by the fastener. The low-resistance grounding device has simple structure, low manufacturing cost and convenient use; and the poleshank can be replaced by dismounting the fastener directly when the poleshank is damaged.
Description
Technical field
The utility model relates to a kind of thunder resisting equipment, particularly a kind of low resistance earthing device.
Background technology
Now in the society along with continuous progress in science and technology, the product category that lightning protection is used is various, and seems in engineer operation and be even more important.The lightning protection product of all trades and professions all adopted steel pipe in the past, metal materials such as angle steel are as earth resistance, its electric conductivity is good, exactly because but what adopt is metal material, so very easily be corroded, product cost height, the resistivity height, poor stability, and when pole piece damages, because earth resistance is a global facility, can not change pole piece and also cause great waste.
The utility model content
The purpose of this utility model be to improve the deficiency of existing product and provide a kind of can be anticorrosive, long service life, simple in structure, easy to use, removable low resistance earthing device when pole piece damages.
For achieving the above object, the utility model provides a kind of low resistance earthing device, it comprises pole piece, module body and securing member, described module body is a tubular structure, described pole piece termination outer wall surface is provided with screw thread, and described securing member inner wall surface is provided with screw thread, and is spirally connected with the pole piece termination, described pole piece is inserted in the module body, and securing member is fixed into one with module body and pole piece.
Further, avoid fractureing when longer dimension or weight are bigger in order to make described module body, that prolongs module body in module body axially and radially is provided with the mesh-supported frame.
Further, the two ends of described pole piece are exposed at the module body outside, and are connected with securing member respectively.
Further, described module body is cylinder or cuboid.
Further, described module body is nonmetal jello.
Advantage of the present utility model is:
1, resistivity is low, electric current can be discharged in the ground rapidly.
2, anticorrosive, pollution-free, the time in useful life is long.
3, simple in structure, low cost of manufacture, easy to use, when pole piece is impaired, can directly change pole piece by pulling down securing member.

Fig. 2 is cylindrical end view for the utility model;
Figure number explanation: 1 pole piece, 2 module bodies, 3 securing members, 4 mesh-supported framves
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
A kind of as shown in Figure 1, 2 low resistance earthing device, it comprises pole piece 1, module body 2 and securing member 3; Described module body 2 is a tubular structure, and described pole piece 1 termination outer wall surface is provided with screw thread, and described securing member 3 inner wall surface are provided with screw thread, and are spirally connected with pole piece 1 termination, and described pole piece 1 is inserted in the module body 2, and securing member 3 is fixed into one with module body 2 and pole piece 1.
That prolongs module body 2 in the described module body 2 axially and radially is provided with mesh-supported frame 4.
The two ends of described pole piece 1 are exposed at module body 2 outsides, and are connected with securing member 3 respectively.
Described module body 2 is cylinder or cuboid.
Described module body 2 is nonmetal jello.
Securing member 3 with pole piece 1 two ends during use is connected with the port of external conductor with lightning protection, lightning protection, the pole piece 1 and the module body 2 of different sizes can be set according to the needs of working condition, when pole piece 1 damages, can pull down the low resistance earthing device, open securing member 3 and change the pole piece 1 of module body 2 inside, saved the waste of resource largely.
The execution mode of the above is one of case study on implementation of the present utility model; be not to limit practical range of the present utility model with this; so the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be encompassed in the protection range of this utility model.
