Description

Technical Field

[0001] The utility model belongs to the technical field of coal mines, and in particular relates to a discharge maintenance device for electrical equipment in underground coal mines. Background Art

[0002] The discharge maintenance device for underground electrical equipment in coal mines is a special device used to repair underground electrical equipment in coal mines. Due to the complex environment, poor ventilation and explosion hazards in coal mines, special safety measures need to be taken when repairing underground electrical equipment to ensure the safety of personnel and equipment.

[0003] When the existing coal mine underground electrical equipment discharge maintenance device is used to maintain some electrical equipment installed at a higher or deeper position, the operator needs to reach the maintenance position by climbing a ladder or other means. The operation is cumbersome and there is a certain risk, which increases the difficulty and risk of the maintenance process. In addition, when the existing discharge maintenance device is used to discharge electrical equipment at a higher or deeper position, due to the limited length of the discharge rod, the insulation effect is often poor, and the charge inside the equipment cannot be completely released, which poses a certain safety hazard. This may lead to a discharge accident caused by charge accumulation during the maintenance process, causing damage or even injury to the operator and equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a discharge maintenance device for electrical equipment in underground coal mines to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model provides a threaded plate, an adjusting screw, an abutment seat and a telescopic rod, so that when the length of the discharge inspection head is adjusted, the telescopic rod can be disengaged from the limit position abutting against it by rotating the adjusting screw, thereby facilitating the adjustment and control of the length of the discharge inspection head, so that the discharge inspection head can be extended and retracted as needed to adapt to electrical devices in different positions for discharge inspection. Once adjusted to a suitable length, the discharge inspection head can be fixed at a specific position by rotating the adjusting screw, thereby ensuring stability and accuracy during the discharge inspection process, thereby improving the convenience and efficiency of operation.

[0024] The adjusting mechanism 2 is arranged inside the mounting base 1, and the adjusting mechanism 2 includes a threaded plate 201, an adjusting screw 202 and a mating seat 203. The threaded plate 201 is installed on the outer wall of the mounting base 1, and the adjusting screw 202 is inserted inside the threaded plate 201. The mating seat 203 is installed on the inner wall of the mounting base 1, and a telescopic rod 204 is inserted inside the mating seat 203.

[0025] Specifically, after the adjusting screw 202 is rotated, it can be telescopically adjusted in the threaded plate 201, so that the adjusting screw 202 can abut and fix the telescopic rod 204, thereby fixing the telescopic rod 204 after the length is adjusted.

[0026] It can be seen from the above that when the length of the discharge inspection head 3 is adjusted, the telescopic rod 204 can be disengaged from the abutment limit on the adjusting screw 202 by rotating the adjusting screw 202, thereby facilitating the length stretching control of the discharge inspection head 3, and by rotating the adjusting screw 202, the discharge inspection head 3 can be limited and fixed after the length adjustment, thereby facilitating the discharge inspection head 3 to perform discharge inspection on electrical devices at different positions.
