Problems solved by technology

[0004] However, because the existing underground cables cannot be seen, they are easily cut off by some construction excavators at one time, and the relevant personnel are not given the opportunity to adjust, thus causing the electrical components involved in the cable to be out of power and cannot be used.

Embodiment 1

[0034] see Figure 1-6 , according to an embodiment of the present invention, a waterproof and breathable underground cable to prevent accidental digging, comprising an outer tube 1 and an inner tube 2, the outer tube 1 is sleeved outside the inner tube 2, and the outer tube 1 includes The connection end 3 and the contact end 4, the contact end 4 is provided with a card slot 5, the connection end 3 is connected to the inner wall of the card slot 5 through a rubber tube 6, and the connection end 3 is connected to the The card slot 5 is matched, and the connecting end 3 and the contacting end 4 are respectively embedded with a first rubber plug 7 and a second rubber plug 8, wherein a set of the first rubber plug 7 and the second rubber plug 8 are A puncture needle 9 is provided throughout, and the puncture needle 9 is connected to the output end of the fan 10. The inner pipe 2 includes a first air duct 11, and a plurality of L-shaped connecting rods 12 are fixed inside the first...

Embodiment 2

[0037] see again Figure 1-6 , for the card slot 5, the inner wall of the card slot 5 is provided with a first rubber ring 23, and the outside of the connecting end 3 is provided with a second rubber ring 24, and the first rubber ring 23 and the second rubber ring 24 matches. Through the first rubber ring 23 and the second rubber ring 24, the connection stability between the connecting end 3 and the draw-in groove 5 can be effectively guaranteed. For the puncture needle 9, the puncture needle 9 includes a needle point 25 and a connecting sleeve 26, and the needle point 25 passes through the first rubber stopper 7, the second rubber stopper 8 and the third rubber stopper 22 in sequence, and the needle point One end of 25 is fixed with the connecting sleeve 26 , and one end of the connecting sleeve 26 communicates with the output end of the fan 10 through the second air pipe 27 . By setting the puncture needle 9, it can be ensured that the airflow driven by the fan 10 can smoo...

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...
