Deep well grounding device for high soil resistivity area

Abstract

The invention provides a deep well grounding device for a high soil resistivity area, which comprises a foundation, a deep well body, a well bottom, a lifting motor, a worm gear reducer, a rotating shaft, a winding wheel and a lifting rope, and is characterized in that the deep well body is arranged in the foundation; a well bottom is arranged at the bottom of the deep well body; the lifting motor is in bolted connection with the lower end of the worm gear reducer; and an output shaft coupling of the worm gear reducer is connected with the right end of the rotating shaft. Through the arrangement of the outer pile casing, the mounting pipe, the vertical seat, the rainproof guide plate, the connecting seat and the telescopic adjusting rod, the problem of soil loss in rainy days can be avoided, well mouth soil of the deep well body can be protected through the outer pile casing and the mounting pipe, soil loss is avoided, and the action position of the telescopic adjusting rod in the connecting seat is adjusted in a telescopic mode. The rainproof guide plate can move in the interior between the vertical seats, and after the protection angle is determined, rainproof and flow guiding work can be carried out, so that the protection effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of grounding electrodes, in particular to deep well grounding devices in areas with high soil resistivity. Background technique [0002] The deep well grounding electrode refers to a vertical grounding body that first drills a hole through a deep well, then puts a vertical grounding electrode of the same length as the design depth into the hole, fills the gap with a low-resistivity material, and finally achieves the purpose of effectively reducing the grounding resistance. [0003] At present, deep well grounding devices in areas with high soil resistivity are widely used. [0004] However, the existing deep well grounding device still has the problems of poor protection effect, easy to cause the dust on the well wall to fall off, inconvenient support and fixation, affecting operational stability, failure of protection in rainy days, prone to soil loss and inability to adjust the length. [0005] Therefore,...
