Abstract
The utility model discloses an earth electric drainage device, comprising an earth cable (1), an earth casing (2), a plurality of fins (3) that is fixedly connected on the side wall of the grounding casing (2), a resistance reducing agent (4) that is provided in the inner cavity of the fins and a corrosion protective covering (5) that is fixedly connected on the external surface of the fins. The utility model has the following advantages of novel structure, automatically reduced resistance, good earth contact, fitted to various geographic environments and long the service life.
Description
Affiliated technical field
The utility model relates to a kind of earth electric drainage device that is applicable to any geographical environment.
Background technology
At present, along with the fast development of modern science and technology, need are more and more higher with the requirement on the equipment interconnection ground of earthing device.Existing earthing device, as: round steel, angle bar, copper rod etc., because earth resistance is big, poor reliability, the life-span is short, can not satisfy the requirement of equipment at different geographical environment groundbed structures, the normal operation that has even influenced equipment.
Summary of the invention
The purpose of the utility model is to provide a kind of improved earth electric drainage device, and it has overcome the above-mentioned deficiency of prior art, and resistance can fall in novel structure voluntarily, contacts with ground well, suitable various geographical environments, long service life.
For reaching above-mentioned purpose; the utility model is taked following technical scheme: the utility model comprises earth cable, ground connection housing; it is characterized in that: some fins that have been fixedly connected on the sidewall of ground connection housing, be equipped with resistance reducing agent in its inner chamber, its outer surface corrosion protective covering that has been fixedly connected.
The utility model is taked technique scheme, has following beneficial effect: the utility model has increased some fins on the sidewall of ground connection housing, has strengthened the contact area with soil, has reduced resistance; In its inner chamber resistance reducing agent is housed, resistance reducing agent can evenly absorb the moisture in the soil, forms the wetland zone around earthing device, and earth resistance reduces, and is reliable and stable; Its outer surface corrosion protective covering that has been fixedly connected has prolonged useful life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model structure diagram.
Embodiment
By shown in Figure 1, the utility model includes: earth cable 1, ground connection housing 2, fin 3, resistance reducing agent 4, corrosion protective covering 5.Fin 3 adopts high-frequency welding manner to be fixed on the outer wall of ground connection housing 2, and resistance reducing agent 4 is housed in the inner chamber of ground connection housing 2, and the composition of resistance reducing agent 4 is: land plaster, sodium sulphate, bentonite.The outer surface of ground connection housing 2 corrosion protective covering 5 that has been fixedly connected.Corrosion protective covering 5 is to adopt active metal alloy, and heat is sprayed on the outer surface of ground connection housing 2.The utility model when construction, will install in placely, fill out the part fine earth earlier, in earthing device, pour into certain water gaging, whole then backfill soil.
