Description

Technical Field

[0001] This utility model relates to the field of underground cable protection technology, specifically to an underground cable that is tear-resistant and moisture-proof. Background Technology

[0002] Because underground cables are buried underground, and the underground environment contains not only soil but also insects and rodents (such as rats), these animals may bite the cables when they pass by. Once the cables are bitten, they can easily damage the power transmission lines and cause various losses. Therefore, it is particularly important to strengthen the anti-bite function of cables. To solve this problem, the existing technology is to thicken the cable sheath, but there is still a risk that it will be bitten through, it's just a matter of time. While setting spikes on the cable sheath to prevent rodents from biting through can prevent it from being bitten through, it is not easy to grip, which affects subsequent maintenance and is not very practical. Moreover, most of them are fixed structures and are inconvenient to disassemble and replace later.

[0003] Therefore, it is particularly important to design an underground cable that is resistant to tearing and moisture to overcome the above-mentioned technical defects and improve its overall practicality. Utility Model Content

[0004] The purpose of this invention is to provide an underground cable that is resistant to tearing and moisture, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

An anti-bite protective sleeve is fitted onto the outside of the cable body. The anti-bite protective sleeve includes multiple telescopic flexible sections, two adjacent telescopic flexible sections are connected by a shaping ring, and multiple sets of equally spaced anti-bite spikes are distributed around the outside of the shaping ring. Operating levers are embedded on the outside of the shaping ring at both ends. Limiting rings are provided at both ends of the anti-bite protective sleeve, and multiple sets of semi-bent clips are distributed around the inside of the limiting ring. The semi-bent clips are connected to the limiting ring by a spring assembly.

[0007] As a preferred embodiment of this utility model, the overall structure composed of the telescopic soft part and the shaping ring part is similar to the gooseneck tube structure.

[0008] As a preferred embodiment of this utility model, the internal structural size of the telescopic flexible part and the shaping ring part is adapted to the external structural size of the cable body.

[0009] As a preferred embodiment of this utility model, the cable body and the anti-bite protective sleeve are designed to be separable.

[0010] As a preferred embodiment of this utility model, the anti-bite protective cover is made of reinforced PVC material, and the anti-bite spikes are designed with a cone-shaped structure with the cone tip pointing outwards.

[0011] As a preferred embodiment of this utility model, the inner side of the semi-curved card is fitted with an anti-slip film.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention relates to an underground cable designed to prevent bites and moisture. A removable and installable anti-bite protective sleeve is provided on the outside of the cable body. This sleeve consists of a multi-section telescopic flexible part and a shaping ring, forming a telescopic structure. When stretched, the anti-bite spikes encase the entire cable body, effectively preventing the cable from being chewed through by rats. For subsequent maintenance, the sleeve can be retracted by closing the operating levers on both sides, making it easy for operators to grip and improving usability. Furthermore, both ends of the sleeve are equipped with semi-bent clips via spring assemblies, which can securely fasten both ends of the cable body, preventing movement of the sleeve and adapting to different cable sizes, thus enhancing its practicality.
