Embodiment 1

[0043] This embodiment provides a protective mechanism, such as figure 1 As shown, it includes: a flexible protective member 1, which is a strip-shaped base material that is spirally coiled, and the strip-shaped base material has a buckled state in which adjacent strip-shaped base materials are fastened to each other along the width direction of the strip; In the closed state, the flexible protective part 1 has an installation cavity suitable for accommodating cables; the locking part 2 is arranged on the flexible protective part 1 and is suitable for limiting the flexible protective part 1 and the cables. For example: when the adjacent strip-shaped base materials in the flexible protective member 1 in this embodiment are snapped together, the adjacent contact surfaces of the strip-shaped base materials can be clamped by generating frictional force. The flexible protective part 1 in this embodiment is flexible, so that the flexible protective part 1 can be used normally under ...

Embodiment 2

[0050]This embodiment provides a protection device, including the protection mechanism in Embodiment 1. The protective device provided in this embodiment also includes a protective tube 4, and the protective tube 4 has a protective cavity suitable for accommodating cables; on the side of the protective tube 4 close to the flexible protective part 1, the flexible protective part 1 is sleeved on the protective tube 4 Outside, and use the locking piece 2 to lock both ends of the flexible protective piece 1. For example, the protective pipe 4 in this embodiment is a galvanized steel pipe, because the galvanized steel pipe has good flexibility, corrosion resistance, high temperature resistance, wear resistance and tensile resistance, and is an excellent power material, so Often used as a protective sleeve for cables. In other optional forms, the protective pipe 4 can also be made of PVC wire pipe, because PVC wire pipe has good tensile resistance, corrosion resistance and insulati...

Embodiment 3

[0052] This embodiment provides a cable conveying system, including the protection device provided in Embodiment 2. The cable conveying system provided in this embodiment further includes a cable, and the cable is installed in the protective device.

Abstract

The invention discloses a protection mechanism, a protection device, a cable conveying system and a cable protection method. The protection mechanism comprises a flexible protection piece and a locking piece, the flexible protection piece is a strip-shaped base material which is spirally coiled, and the strip-shaped base material has a buckling state that adjacent strip-shaped base materials are buckled with each other in the strip-shaped width direction of the strip-shaped base material; and in the buckling state, the flexible protection piece is provided with an installation cavity suitable for containing a cable. The locking piece is arranged on the flexible protection piece and is suitable for limiting the flexible protection piece and the cable. The flexible protection piece is a strip-shaped base material which is spirally coiled, and when the flexible protection piece is used, the strip-shaped base material can be separated from each other or buckled in the width direction so that the flexible protection piece can quickly mount and dismount the cable; and the flexible protection piece has certain deflection, cables with bends and corners can be bent according to the required bending degree, the installation protection of the cables is realized by matching with the existing straight-pipe galvanized steel pipe, and the safety of cable conveying is further improved.

Description

technical field [0001] The invention relates to the technical field of cable protection, in particular to a protection mechanism, a protection device, a cable conveying system and a cable protection method. Background technique [0002] Cables undertake the task of power transmission and distribution. In the process of modern city construction, the use of cables for power transmission and distribution is conducive to reducing the impact of natural factors and the environment on power lines and making the city appearance neat and tidy. [0003] In the prior art, in order to realize the protective effect of the cable, the cable application environment may be affected by hidden dangers such as man-made damage, mechanical damage, vibration, water immersion, corrosive chemicals, etc., and it is necessary to seal the cable through a metal tube for protection throughout the entire process. Usually, galvanized steel pipe is used to cover the outside of the cable, and the galvanized ...
