Problems solved by technology
If it is raining or the ground is wet, there will be a hidden danger of electric leakage at the cable joint
Once leakage occurs, it will not only cause the substation to "trip", causing huge economic losses to the production and operation of the enterprise, but also bring life danger to the production personnel on site

Abstract
The invention discloses a protective device for a cable joint in a sediment mining area, which comprises a fixed plate, a supporting device, a slide rail, a sliding sleeve, a threaded column, a pretightening force adjusting nut, a height adjusting nut, a fixed semi-circular ring, and a movable semi-circular The ring and the clamping limit device, through the function of the legs, make the present invention firmly placed on the ground, erect the cable, effectively eliminate the hidden danger of electric leakage in the cable joint when it rains or when the ground is wet, avoid the cable short circuit phenomenon, and The operation is simple and fast. By loosening and tightening the jacking bolts, it is convenient to adjust the position of the sliding sleeve, so it is convenient to adjust the position of the cable, and the number of sliding sleeves can be increased on the slide rail according to the needs, which is convenient to use. During the process, the first coil spring has the function of shock absorption, and the shock absorption effect of the first coil spring can be adjusted by adjusting the pre-tightening force adjustment nut, and the height of the cable erection can be easily adjusted by adjusting the height adjustment nut, and the structure is simple.
Description
technical field [0001] The invention relates to the technical field of mining equipment, in particular to a cable joint protection device for sand mining mining areas. Background technique [0002] Mining equipment is operated by connecting the 6KV voltage to the equipment with a power supply cable, and the power supply cable is placed on the ground in the open air. As the equipment moves, the power supply cable also needs to move and extend accordingly. Due to long-term friction with the ground or other reasons such as equipment failure, the outer insulation of the cable is often damaged or short-circuited. Usually, maintenance personnel will continue to use the cable after wrapping and repairing the cable at the position where the outer insulation of the cable is damaged or short-circuited. [0003] Generally, a power supply cable like this will have 3 to 5 connectors as it is used for a long time. If it is raining or the ground is wet, there will be a hidden danger of e...
