Title:
DEEP WELL GROUNDING ELECTRODE AND DEEP WELL GROUNDING ELECTRODE MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/036608
Kind Code:
A1
Abstract:
A deep well grounding electrode and a deep well grounding electrode monitoring system. The deep well grounding electrode comprises a feeding rod (1), a feeding head (2), a steel sleeve (3) with a diameter smaller than the aperture of a well body, a temperature measurement optical cable (4), an exhaust pipe (5), and a drainage cable (6); the steel sleeve (3) is located in the well body, and is coated with an insulating erosion-resistant layer (7) from a certain depth to the top; the feeding head (2) is located at the bottom of the steel sleeve (3), and comprises a grouting device capable of pumping coke liquid; the feeding rod (1), the temperature measurement optical cable (4), the exhaust pipe (5), and the drainage cable (6) are located in the steel sleeve (3); the temperature measurement optical cable (4) extends from a bottom end of the feeding rod (1) to a monitoring module; the exhaust pipe (5) extends from the bottom end of the feeding rod (1) to the ground; and one end of the drainage cable (6) is welded on the feeding rod (1), the other end extends to the monitoring module, and the drainage cable (6) is fixed to the feeding rod (1) by bolts. By means of a construction method of the deep well grounding electrode, the purpose of enhancing direct current deep ground layer diffusion can be realized, and the influence of the grounding electrode on the surface environment is greatly reduced.
