Abstract

The invention discloses a waterproof and breathable underground cable capable of preventing mistaken digging and breaking. The waterproof and breathable underground cable comprises an outer pipe and an inner pipe, wherein the outer pipe sleeves the inner pipe, the outer pipe comprises a connecting end and a contact end, a clamping groove is formed in the contact end, the connecting end is connected with the front of the inner wall of the clamping groove through a rubber pipe, the connecting end is matched with the clamping groove, a first rubber plug and a second rubber plug are embedded in the connecting end and the contact end respectively in a penetrating mode, a puncture needle is arranged on the first rubber plug and the second rubber plug in one set in a penetrating mode, the puncture needle is connected with the output end of the draught fan, the inner pipe comprises a first air pipe, and a plurality of L-shaped connecting rods are fixedly arranged in the first air pipe. The waterproof and breathable underground cable has the beneficial effects that the length of the whole outer pipe is released, the flexibility of the cable is increased, the probability of being broken by digging is reduced, the opportunity of adjusting the digging angle is provided for related personnel, and the situation of power failure of corresponding electrical apparatus elements is avoided.

Description

technical field [0001] The invention relates to the field of underground cables, in particular to a waterproof and air-permeable underground cable that prevents accidental digging. Background technique [0002] The shape of the cable is similar to a rope. It is usually twisted by multiple groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulating coating; the cable is mostly erected in the air Or installed underground or underwater for telecommunications or power transmission; in order to ensure the normal and stable operation of the cable, the cable must have basic safety performance, such as wear resistance, flame retardancy, fire resistance, etc., and depending on the application occasion It also needs to have corresponding characteristic properties, such as insect repellency, anti-corrosion, cold resistance, etc. [0003] The Chinese application number is CN20151053...
