Abstract
The utility model discloses a cable inlet device capable of preventing leakage and water inflow for an underground power distribution room, which relates to the technical field of cable installation and comprises an upper half wire inlet cylinder, a lower half wire inlet cylinder and an inner wire inlet cylinder, and the upper half wire inlet cylinder is located at the upper end of the lower half wire inlet cylinder. An outer wire inlet is formed in the middle of the end of one side of the upper half wire inlet cylinder and the middle of the end of one side of the lower half wire inlet cylinder, outer fixing rings are arranged at the ends of the other sides of the upper half wire inlet cylinder and the lower half wire inlet cylinder, and connecting lugs are arranged on the side walls of the upper half wire inlet cylinder and the lower half wire inlet cylinder and the side walls of the two sets of outer fixing rings. And first bolts are arranged in the middles of the connecting lugs, first nuts are arranged on the outer walls of the lower portions of the first bolts, and a filling cavity is formed in the middle of the inner wall of the upper half wire inlet cylinder and the middle of the inner wall of the lower half wire inlet cylinder. The anti-seepage water inlet cable inlet device for the underground power distribution room has a better anti-seepage effect, and the installation process is simpler and more convenient.
