Background technique

In recent years, with the construction and development of cities, power cable lines have gradually shown the characteristics of occupying less urban space, being safer and more stable than traditional overhead lines. However, during operation, power cable lines will inevitably cause cable line accidents due to external damage, natural factors, poor manufacturing technology, insulation aging and moisture, and many other reasons. Moreover, due to historical reasons, the development of distribution network shows regional imbalance. In the old urban areas of some cities, cables are often stacked together in trenches and wells, blocking the cable ducts and making maintenance difficult, especially when it comes to connecting wells, tee wells, and four-way wells. When opening the well, the cables in the trench are stacked across each other, and the space inside the well is small. Some on-site cranes cannot enter or the safety distance is not enough after the boom is raised. Some on-site emergency repair personnel need to use tools such as crowbars and hemp ropes, and a lot of manpower is invested to lift the well. Pulling the faulty cable to the appropriate position consumes a lot of time and energy, which reduces the efficiency of the emergency repair work. These unfavorable objective conditions bring greater difficulties and safety hazards to the construction and emergency repair personnel's emergency repair work.

Based on the above situation, designing a device that can shorten the cable repair time, save the investment of repair personnel, restore power supply faster, and enhance the company's power supply reliability and corporate image has become an urgent problem to be solved.
