Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, specifically to an MPP power cable protection pipe. Background Technology

[0002] Most power cable lines are installed by burying them underground. The insulation layer of cables buried underground is often damaged by equipment due to excavation during subsequent construction. Therefore, in some special construction environments, it is necessary to put a protective sleeve on the outside of the cable in a special construction section to protect the power cable.

[0003] According to a public notice of an MPP power cable protection pipe (publication number: CN117674002A), the above application includes a protective outer pipe, a limiting mechanism is provided on the outer side of the protective outer pipe, an installation mechanism is provided at the lower end of the limiting mechanism, the limiting mechanism includes a fixing plate movably connected to the outer side of the protective outer pipe, a limiting plate movably connected to the lower side of the outer side of the protective outer pipe near the fixing plate, and a docking frame movably connected to the inner side of the fixing plate via a rotating shaft.

[0004] However, when installing these protective tubes, the cable must first be disconnected before the protective tube can be fitted onto the outside of the cable. Once the power cable is cut, it must be reconnected. The joint is likely to become the weakest link in the cable system, affecting insulation performance, mechanical strength, and even causing safety problems such as overheating and short circuits. At the same time, high-voltage cable joints are particularly complex and must use professional heat shrinking and cold shrinking processes. The construction process is demanding and risky. In view of this, we propose an MPP power cable protective tube. Utility Model Content

[0005] The purpose of this utility model is to provide an MPP power cable protection pipe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an MPP power cable protection pipe, comprising a cable body, wherein a protection pipe assembly is disposed on the outer wall of the cable body, and the protection pipe assembly includes:

[0009] Preferably, there are two sets of outer tubes and inner tubes, with the two sets of outer tubes interlocked and the two sets of inner tubes interlocked. The outer wall of the outer tube is fitted with a mounting bracket, which fixes the position of the cable body and the protective tube assembly.

[0010] Preferably, the outer tube and the inner tube are staggered, the axes of the outer tube and the inner tube coincide, and the axis of the inner tube coincides with the axis of the cable body.

[0012] Preferably, the slider is slidably connected to the positioning groove, and the clamp wraps around the cable body, thereby fixing the cable body and stabilizing the position of the cable body.

[0013] Preferably, the outer wall of the cable body is wrapped with a buffer membrane, and an anti-puncture membrane is fixedly connected to the outer wall of the buffer membrane.

[0014] Preferably, the puncture-resistant membrane is fitted to the inner wall of the clamp, and the buffer membrane is fitted to the outer wall of the cable body.

[0015] Compared with the prior art, this utility model provides an MPP power cable protection pipe, which has the following beneficial effects:

[0016] 1. This MPP power cable protection pipe, through the installation of a protection pipe assembly, connects two sets of outer and inner pipes to achieve non-cable-break installation, without damaging the original cable structure. It can directly wrap the cable from the outside without cutting the cable body. It is suitable for the renovation and reinforcement of cable lines that have been laid or are in operation. The outer and inner pipes are arranged in an interlaced structure with concentric axes. The outer pipe provides primary protection close to the cable, while the inner pipe provides a second layer of protection against external forces, improving the overall pressure resistance, wear resistance, and lateral pressure resistance. It can also prevent cable damage caused by external construction or collapse. The size of the clamp structure is adjustable, and the same protection pipe assembly can be used for various specifications of cables. It can adapt to the simultaneous wrapping of single or multiple cable bodies, improving on-site versatility and economy.

[0017] 2. This MPP power cable protection pipe, through the setting of a buffer film and an anti-puncture film, the buffer film, as a soft buffer layer, disperses stress and reduces local pressure, avoiding long-term wear, aging or insulation damage caused by the clamp directly contacting the surface of the cable body. The anti-puncture film is a hard or puncture-resistant material to resist external sharp objects and prevent sharp objects from puncturing or causing local damage to the cable body.
