[0002] The mine electromechanical equipment is an important component part in the mine production process, covering various electrical and mechanical equipment, such as electric motor, transformer, crane, ventilation system, transportation equipment, etc. These devices usually work in harsh environmental conditions and are affected by factors such as humidity, high temperature, and dust, which are prone to electric leakage. Electric leakage not only causes damage to the equipment and production stagnation, but also may cause safety accidents. Therefore, it is particularly important to detect electric leakage of mine electromechanical equipment.

[0003] The existing electric leakage detection device for electromechanical equipment (publication number: CN212905368U) has at least the following disadvantages: Although the above device protects the electric leakage monitor by a protective box and installs the detection touch head on the surface of the equipment using a C-shaped plate for detection, in actual use, the operator needs to manually take out the detector from the protective box, which is relatively cumbersome. At the same time, after the detector is taken out, the protective box cannot continue to protect it, increasing the risk of equipment damage and the influence of the environment on the detector. The above problems not only reduce the detection efficiency, but also affect the reliability and effect of detection, resulting in poor overall performance of the device. Therefore, we propose the present utility model. UTILITY MODEL CONTENT
