Abstract

The utility model belongs to a ground body of grounding line device, wherein, the ground body is a metal pipe 2; a series of holes 3 are processed on the pipe wall of the metal pipe 2; one end of the metal pipe 2 is a cone 4. When the utility model is in use, the ground body is driven into underground and connected with equipment through a conductor 1, and resistance-reducing agent is timely injected into the metal pipe 2; the resistance-reducing agent can fully and rapidly infiltrate into soil layer through the holes 3 on the metal pipe 2, which improves resistance-reducing effect. The utility model has the advantages of simple structure, good grounding effect and convenient use as well as maintenance, which is particularly applicable to maneuvering equipment.

Description

A kind of earth electrode of grounding wire device

The utility model relates to a kind of earth electrode of grounding wire device, the porose earth electrode of particularly a kind of metal pipe-wall processing.

Setting up grounding wire device at present under the wild environment adopts ground nail, ground connection row etc. to make earth electrode usually.When adopting ground nail, have that contact area is little over the ground, the bigger shortcoming of ground resistance as earth electrode; When adopting ground connection row to make earth electrode, exist volume big, bury (removing receipts) inconvenience underground, be not easy to water shortcomings such as resistance reducing agent.

The purpose of this utility model is to solve general earth electrode contact area is little over the ground, and the ground resistance is bigger, is not easy to water problems such as resistance reducing agent.

The purpose of this utility model is achieved in that

Adopt metal tube to make earth electrode, the one end is processed into cone, so that be driven underground (in the shallow relatively sandstone area of soil property or beach, sea (river, river) when ground wire is installed, the metal tube level can be imbedded underground appropriate depth and connect plastic tube to more than the ground) at the mouth of pipe.Process a series of holes (upwards reserve two bigger holes the end of from, when setting up earth electrode, can pass iron staff therein) on the tube wall of metal tube for strike provides stress point every 40-60 centimetre of symmetry.After such earth electrode is driven underground, can pour into resistance reducing agent easily in metal tube, the resistance reducing agent that pours into can utilize the hole of opening on the tube wall fully to infiltrate earth electrode soil on every side, reaches the purpose that reduces earth resistance.

Figure one, the earth electrode schematic diagram

Below, be illustrated in conjunction with the embodiments.In the accompanying drawing

1-lead 2-metal tube

3-hole 4-cone

One section metal tube 2 of length intercepting on demand, cone 4 is processed in the lower end of metal tube 2, processes a series of holes 3 on the tube wall of metal tube 2.Lead 1 is connected on the metal tube 2, has just constituted this earth electrode.

During use this earth electrode is driven underground, links to each other with equipment, and in metal tube 2, inject resistance reducing agent in good time, can make resistance reducing agent infiltrate soil layer fully, rapidly, improve resistance reducing effect by the hole on the metal tube 23 by lead 1.

The earth connection that adopts the utility model to install, have simple in structure, easy to maintenance, earthing effect is good Good, as to be convenient to install and remove receipts advantage is particularly suited for the use of motor device.

Claims (1)

1, a kind of earth electrode of being made up of lead 1, metal tube 2, cone 4 is characterized by metal tube 2 and is processed with one group of hole 3.
