TECHNICAL FIELD
[0001] The present application relates to the field of cable laying, in particular to a silicon core pipe facilitating cable insertion. BACKGROUND
[0002] The silicon core pipe is a plastic pipe used for protecting cables. When in use, the cable is inserted into the silicon core pipe, and the silicon core pipe surrounding the cable can protect the cable from damage.
[0003] However, when the cable is inserted into the silicon core pipe, a large friction will be generated between the cable and the inner wall of the silicon core pipe, resulting in a large resistance to the cable insertion, which greatly increases the difficulty of cable insertion and reduces the efficiency of cable insertion. CONTENT OF THE INVENTION
[0004] In order to overcome the shortcomings of the prior art, the present application provides a silicon core pipe facilitating cable insertion.
[0005] The silicon core pipe provided by the present application adopts the following technical solution:
[0006] The silicon core pipe facilitating cable insertion comprises a pipe body and a wire layer arranged on the inner wall of the pipe body, and a plurality of wire grooves are arranged on the wire layer in a circumferential direction of the pipe body, each wire groove extending along the axial direction of the pipe body.
[0007] By adopting the above technical solution, the plurality of wire grooves can effectively reduce the contact area between the cable and the pipe body, reduce the friction between the cable and the pipe body, and reduce the resistance to the cable insertion, thereby reducing the difficulty of cable insertion and improving the efficiency of cable insertion.
[0008] In a specific embodiment, the wire layer comprises a plurality of wire strips arranged in the circumferential direction of the pipe body, and each wire groove is formed between two adjacent wire strips.
[0009] In a specific embodiment, the cross section of the wire strip is arc-shaped.
[0010] By adopting the above technical solution, the smoothness of the wire strip is effectively improved, and the resistance to cable insertion is reduced.
[0011] In a specific embodiment, the pipe body comprises a penetration-resistant layer, and the wire layer is arranged on the inner wall of the penetration-resistant layer.
[0012] By adopting the above technical solution, the penetration-resistant layer can prevent ultraviolet light from penetrating the pipe body, thereby preventing the cable from being damaged under the irradiation of ultraviolet light.
[0013] In one specific implementation, the thickness of the anti-permeation layer is greater than the thickness of the wire layer.
[0014] By using the above technical solution, the anti-permeation effect of the anti-permeation layer is effectively improved.
[0015] In one specific implementation, the pipe body further comprises a protective layer arranged on the outer wall of the anti-permeation layer, and the outer wall of the protective layer is smooth.
[0016] By using the above technical solution, the protective layer can protect the pipe body, and the smooth outer wall of the protective layer can prevent it from generating large friction with the external structure during installation, thereby facilitating the installation of the silicon core pipe in the external structure.
[0017] In one specific implementation, at least one guide line is coated on the protective layer, and the guide line extends along the axial direction of the pipe body.
[0018] By using the above technical solution, the guide line can serve as a guide for the installation of the silicon core pipe, thereby preventing the silicon core pipe from generating large deflection during installation.
[0019] In one specific implementation, the pipe body further comprises an oxygen barrier layer arranged between the anti-permeation layer and the protective layer.
[0020] By using the above technical solution, the oxygen barrier layer can block oxygen, thereby avoiding excessive oxygen from penetrating into the pipe body and causing mold growth of the cable.
[0021] In one specific implementation, the pipe body further comprises a heat preservation layer arranged between the anti-permeation layer and the oxygen barrier layer.
[0022] By using the above technical solution, the heat preservation layer can achieve heat preservation of the cable, thereby avoiding damage of the cable in extreme temperature environment.
[0023] In one specific implementation, the pipe body further comprises a buffer layer arranged between the anti-permeation layer and the wire layer.
[0024] By using the above technical solution, the buffer layer can serve as a buffer between the cable and the pipe body, thereby avoiding excessive rigid impact between the cable and the pipe body and causing abrasion.
[0025] In summary, the present application has at least one of the following beneficial technical effects:
[0026] The plurality of wire grooves can effectively reduce the contact area between the cable and the pipe body, reduce the friction between the cable and the pipe body, reduce the resistance received by the cable during threading, thereby reducing the threading difficulty of the cable and improving the threading efficiency of the cable.
