Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cable protection pipe technology, specifically relating to a high-strength MPP cable protection pipe. Background Technology
[0002] MPP cable protection pipe is a type of protective pipe with wide applications. It effectively protects cables and facilitates cable laying when buried underground. It also reduces the corrosive effects of underground moisture and microorganisms on the cables. Protecting cables with MPP cable protection pipe can extend their service life and reduce the hassle of cable maintenance.
[0003] Existing MPP cable protection pipes are usually made of single or double layers of material, which have weak buffering capacity against external impacts. In addition, the strength of the MPP cable protection pipes themselves is usually limited, making it difficult to protect the cable well under external impacts. Furthermore, during construction, MPP cable protection pipes sometimes need to be dragged in relatively rough environments or buried. Traditional MPP cable protection pipes have poor wear resistance and compressive strength.
[0004] Therefore, a new type of MPP cable protection pipe is needed to meet the above requirements. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-strength MPP cable protection pipe, the specific solution of which is as follows:
[0006] A high-strength MPP cable protection pipe includes a pipe body with connectors at both ends. Each connector includes an annular plate with a connecting cylinder attached to it. The connecting cylinder is fixed to the pipe body by an adhesive layer. The annular plate also has multiple through holes. A rubber gasket is provided on one side of one of the annular plates. The pipe body includes an inner rubber layer, a braided layer on the outside of the inner rubber layer, a middle rubber layer on the outside of the braided layer with partial penetration into the braided layer, a metal mesh layer on the outside of the middle rubber layer, and an outer rubber layer on the outside of the metal mesh layer with partial penetration into the metal mesh layer.
[0007] Based on the above, the pipe body has a cross-shaped support plate frame inside, and the inner side of the inner adhesive layer has a groove for the support plate frame; the support plate frame is made of polycarbonate.
[0008] Based on the above, the material of the inner rubber layer is chlorosulfonated polyethylene rubber.
[0009] Based on the above, the outer adhesive layer is made of neoprene rubber.
[0010] Based on the above, the wear-resistant layer is made of butyl rubber containing metal powder.
[0011] Based on the above, a wear-resistant layer is provided on the outside of the outer adhesive layer, and the wear-resistant layer is made of butyl rubber containing metal powder.
[0012] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:
[0013] The high-strength MPP cable protection pipe provided by this utility model can have good flame retardancy, wear resistance and signal shielding performance while ensuring its own structural strength. It is also easy to assemble pipes together. The structure is ingenious and practical. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0021] Example
[0022] like Figure 1-5As shown, this utility model provides a high-strength MPP cable protection pipe, including a pipe body 1. Both ends of the pipe body 1 are provided with connectors 2. Each connector 2 includes an annular plate 2-1. A connecting cylinder 2-2 is provided on the annular plate 2-1. The connecting cylinder 2-2 is fixed to the pipe body 1 by an adhesive layer 4. The annular plate 2-1 is also provided with multiple through holes 2-3. A rubber gasket 3 is provided on one side of one of the annular plates 2-1. The pipe body 1 includes an inner rubber layer 1-1. A braided layer 1-2 is provided on the outside of the inner rubber layer 1-1. A middle rubber layer 1-3 is provided on the outside of the braided layer 1-2. The middle rubber layer 1-3 partially penetrates into the braided layer 1-2. A metal mesh layer 1-4 is provided on the outside of the middle rubber layer 1-3. An outer rubber layer 1-5 is provided on the outside of the metal mesh layer 1-4. The outer rubber layer 1-5 partially penetrates into the metal mesh layer 1-4.
[0023] To ensure the overall structural strength of the protective pipe, a cross-shaped support plate frame 5 is provided inside the pipe body 1, and a groove 1-1-1 for the support plate frame 5 is provided on the inner side of the inner adhesive layer 1-1; in addition, the support plate frame 5 is made of polycarbonate.
[0024] To ensure the flame-retardant and corrosion-resistant properties of the protective tube, the inner rubber layer 1-1 is made of chlorosulfonated polyethylene rubber.
[0025] To further ensure the flame-retardant performance of the protective tube, the outer rubber layers 1-5 are made of neoprene rubber.
[0026] To ensure the wear resistance of the protective tube, a wear-resistant layer 1-6 is provided on the outside of the outer rubber layer 1-5. The wear-resistant layer 1-6 is made of butyl rubber containing metal powder.
[0027] It should be noted that the inner diameter of the main pipe body 1 and the inner diameter of the annular plate 2-1 are both R.
[0028] In practical use, the protective pipe simply needs to be passed through the channel between the support plate frame 5 and the pipe body 1. When different protective pipes need to be connected, simply connect the protective pipes together, then pass bolts through the through holes 2-3 on the annular plate 2-1 and tighten them with the corresponding nuts.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
