CN2566481Y - Earthing pipe - Google Patents

Abstract

The utility model discloses a novel ground pipe which is mainly composed of a ground pipe which is formed by the compound of a conductive pipe and a lining pipe. The utility model is characterized in that the lining pipe is provided with a reinforcing rib. The novel ground pipe has reasonable structure. Because the lining pipe is provided with the reinforcing rib, the novel ground pipe has the stiffness of an iron pipe and toughness. The weight of the novel ground pipe is only 1/5 of the existing ground pipe. The utility model has the advantages of small size, light weight, high conductivity, convenient transportation and convenient construction and can simultaneously satisfy strength requirement.

Description

Novel grounded pipe

Technical field:

The utility model relates to a kind of electric equipment, high-tension line, transformer station, the lightning-arrest earthing device in warehouse, particularly relates to the earthing device that a kind of ground pipe is a multiple tube.

Background technology:

The application of zinc-plated steel ground pipe has the history of decades, the electric equipment in China's overwhelming majority area, high-tension line, transformer station, the lightning-arrest ground connection in warehouse are all adopted this product at present, this product low-carbon alloy steel pipe manufacturer, 2.7 meters of length, 42 millimeters of diameters, ground end hot extrusion or strike out taper, the anticorrosion process of galvanizing by dipping, about 12 kilograms of weight are adopted in the surface.Use through reality, exist following defective: volume is big, Heavy Weight, conductance is low, construction is inconvenient, easy-to-rust.

Summary of the invention:

Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, and volume is little, in light weight, conductance is high and can satisfy the novel grounded pipe of requirement of strength simultaneously.The technical scheme that its technical problem that solves the utility model adopts is, a kind of novel grounded pipe mainly is made up of ground pipe, and ground pipe is to be composited by contact tube and bushing pipe, and its characteristics are: bushing pipe is provided with reinforcement.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, the utility model is rational in infrastructure, be skillfully constructed, because bushing pipe is provided with reinforcement, the stiffness that makes it existing iron pipe is flexible again, and weight only is 1/5th of former ground pipe, be convenient to transportation, construction, the tool promotional value.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 be among Fig. 1 A-A to cutaway view.

Embodiment:

Referring to Fig. 1, a kind of novel grounded pipe mainly is made up of ground pipe, the contact tube 3 that ground pipe can be made by the red copper material and be composited by the bushing pipe 4 that the highstrenghtpiston makes.The top of ground pipe is fixed with a steel cap 2, be provided with ground connection band steel 1 outside the steel cap 2, and the bottom of ground pipe is provided with a ground pipe drift 6 by pin 5.Referring to Fig. 2, wherein, be provided with cross reinforcement 7 in the bushing pipe 4.
