[0040] Working principle: First, in the process of moving with the mining equipment or moving due to changes in the site environment, if it encounters external mine falling impact or equipment pulling and other unexpected situations, the rubber sealing pad 3 will play a role first. The rubber sealing pad 3 can quickly absorb part of the external force, while the remaining impact force is transmitted to the damping spring 4. The damping spring 4 will accurately buffer and disperse the external force according to the size and direction of the impact force through its own stretching and contracting changes, avoiding the direct effect of strong impact force on the cable, effectively protecting the cable skin from being worn and the internal circuit from being pulled apart, and providing all-round protection for the stable transmission performance of the cable; secondly, in the presence of high temperature environment, fire hazard or in a humid environment and other harsh conditions in the mining site, the protective isolation box 5 and its internal rock wool 6, flame-retardant foam 7 and surface fireproof coating will work together to build a safe defense line for the cable. The protective isolation box 5 forms the first physical protection barrier. The rock wool 6 carefully filled in the inner layer can effectively block the entry of external high temperature heat. Even if the surrounding environment temperature rises sharply, it can also isolate heat to a large extent to prevent the cable from overheating and causing performance degradation, damage and other problems. When encountering open flames or high temperatures, the flame-retardant foam 7 can quickly expand and form a dense barrier layer to suppress the spread of fire and prevent the flame from contacting the cable, further reducing the risk of fire damage to the cable. The fireproof coating on the surface of the protective isolation box 5 has good high temperature resistance and flame retardant performance. When a fire occurs, it can form a solid protective film on the surface, slowing down the erosion speed of the protective isolation box 5 by the flame, and cooperating with the rock wool 6 and flame-retardant foam 7 to create a relatively safe internal environment for the cable. At the same time, the rubber sealing pad 3 also plays a role in preventing moisture to a certain extent. It tightly adheres to the surface and can block the entry of external humid air into the protective isolation box 5, preventing the cable from short-circuiting, aging and other faults due to moisture, and ensuring the safe operation of the cable in various harsh environments, effectively ensuring that the mining operation can proceed smoothly and efficiently, reducing the downtime of equipment due to cable failure and the increase in maintenance costs.
