Problems solved by technology

Existing cables have poor stretchability and flexibility. When uneven settlement occurs on the ground, the cable protective cover will be stretched, compressed or deflected, which will damage the cable protective cover and fail to protect the cable.

Embodiment 1

[0024] like figure 1 and figure 2 As shown, the present invention includes a sleeve body 1, and the sleeve body 1 is composed of a flexible section 2. The flexible section 2 includes a number of flexible ring bodies 2.1 arranged along its axial direction. The flexible ring bodies 2.1 are circular, and the hollow holes of the flexible ring bodies 2.1 constitute the cable channel 2.2. Two adjacent flexible ring bodies 2.1 form a flexible monomer 2.3. The outer peripheral surfaces of the two flexible ring bodies 2.1 in the flexible monomer 2.3 are connected, and the inner peripheral surfaces of the two adjacent flexible ring bodies 2.1 in the adjacent flexible monomers 2.3 are connected. Each flexible ring body 2.1 is provided with a first bending portion 2.4 and a second bending portion 2.5, the bending directions of the first bending portion 2.4 and the second bending portion 2.5 are opposite, and the corresponding two flexible ring bodies 2.1 in the flexible monomer 2.3 The...

Embodiment 2

[0030] like image 3 As shown, the difference between this embodiment and embodiment 1 is that: the sleeve body 1 further includes a straight pipe section 3 , and the straight pipe section 3 communicates with the flexible section 2 and is arranged at intervals. The straight pipe section 3 cannot be bent and stretched, so the plastic deformation of the protective cover can be reduced, the protective cover has a certain compression resistance, and excessive bending of the protective cover can be avoided.

Abstract

The invention relates to a power cable protection sleeve. The power cable protection sleeve comprises a sleeve body, wherein the sleeve body comprises a flexible segment, the flexible segment comprises a plurality of flexible annular bodies arranged along an axial direction of the flexible segment, hollow holes of the flexible annular bodies form a cable passage, two adjacent flexible annular bodies forma a single flexible body, outer circumferential surfaces of the two flexible annular bodies in the single flexible body are connected, inner circumferential surfaces of two adjacent flexible annular bodies in two adjacent single flexible bodies are connected, each flexible annular body is provided with a first bending part and a second bending part, bending directions of the first bending part and the second bending part are opposite to each other, and the first bending part and the second bending part corresponding to two flexible annular bodies in the single flexible body are adaptiveto each other. The power cable protection sleeve is reasonable in structural design, is convenient to use, has favorable flexibility and bending performance and can be suitable for differential settlement of ground to a certain extent, and damage to the protection sleeve is prevented.

Description

technical field [0001] The invention relates to a power cable protective cover. Background technique [0002] Power cables are cables used to transmit and distribute electrical energy, and are usually laid underground to relieve pressure on ground space. When the cable is laid, it is necessary to add a protective sheath to the outside to protect the cable. Existing cables have poor stretchability and flexibility. When uneven settlement occurs on the ground, the cable protective sheath is stretched, compressed or deflected, so that the cable protective sheath is damaged and the cable cannot be protected. Contents of the invention [0003] The invention provides a power cable protective cover, which has a reasonable structural design, is convenient to use, has good stretchability and flexibility, can adapt to a certain degree of uneven settlement on the ground, and avoids the occurrence of damage to the protective cover. The purpose of better protecting the power cable is ...
