Embodiment 1

[0042] Embodiment 1 provides a kind of elastic ring electrode, such as Figure 1-5 shown, including: metal bracket and elastic ring conductor;

[0043] The metal bracket is composed of an upper annular part 10 and a lower hollow cylindrical part 20, and the upper part of the lower hollow cylindrical body 20 is connected to the inner ring of the upper annular part 10;

[0044] The elastic ring conductor includes an elastic liner 30 and a metal mesh conductor 40 coated on the surface of the elastic liner;

[0045] The elastic liner 30 is in the shape of a torus and is composed of an outer skin and fillers. In order to facilitate shaping and increase the contact area between the electrode mesh conductor and the ground surface, the outer skin is made of latex or rubber-like elastic material, and the filling The material is oily soil (plasticine), preferably, the making material of the liner is synthetic rubber.

[0046] The diameter and inner diameter of the elastic liner 30 aft...

Embodiment 2

[0069] Embodiment 2 provides a method for manufacturing the elastic ring electrode of Embodiment 1, comprising:

[0070] Step S1, using a lathe to process a 5mm thick copper plate into a first ring plate and a second ring plate, the first ring plate is used as the upper ring portion 10, and the second ring plate is used as the counterweight plate 50 ;

[0071] Step S2, using a lathe to process a 5mm thick copper plate into a hollow cylinder 20 as the lower hollow cylinder part;

[0072] Step S3, welding the inner wall of the upper annular part 10 to a designated position below the top of the outer wall of the lower hollow cylindrical part 20; the designated position is 5 mm to 10 mm from the top of the lower hollow cylindrical part 20.

[0073] Step S4, using about 210000mm 3 The oily soil is made into an oily soil cylinder with a diameter of 60mm and a length of 450mm. Cut the rubber film into a rectangle of 400mm*900mm, and then cover it outside the oily soil cylinder to c...

Abstract

The invention relates to an elastic annular electrode for reducing grounding resistance and a manufacturing method of the elastic annular electrode. The elastic annular electrode comprises a metal support and an elastic annular conductor, wherein the metal support is composed of an upper circular ring part and a lower hollow cylinder part, and the upper portion of the lower hollow cylinder part isconnected with an inner ring of the upper circular ring part; the elastic annular conductor comprises an elastic inner container and a metal net-shaped conductor wrapping the surface of the elastic inner container; the elastic annular conductor is arranged around the lower hollow cylinder, and the metal net-shaped conductor at the upper part of the elastic annular conductor is welded on the bottom surface of the upper circular ring part; the elastic annular electrode further comprises a balance weight disc, and the balance weight disc is detachably arranged above the upper circular ring part.According to the elastic annular electrode provided by the invention, earth ramming, watering or drilling is not needed in the construction process, and the grounding resistance of bare rock or cement ground can be effectively reduced.

Description

technical field [0001] The invention relates to the field of geophysical exploration, in particular to an elastic ring-shaped electrode for reducing grounding resistance and a manufacturing method thereof. Background technique [0002] In the field of electrical prospecting, iron or steel brazing electrodes are generally used as power supply electrodes at present, and electrodes such as strip-shaped thin copper sheets, strip-shaped copper wire braids, aluminum plates, and iron plates that can be rolled up and carried. In some special terrains such as exposed areas of high-resistance hard rock and areas covered by cement ground, it will be very difficult to ground the electrode or it is impossible to drive the electrode into the ground at all. The traditional response method is the rammed earth method, that is, to make a soil mound in the construction area by artificially mounding the soil, and to ensure the viscosity and electrical conductivity of the mound by pouring salt w...
