Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, specifically to a corrosion-resistant cable protection pipe. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of several or several groups of conductors. Cables are generally buried underground during installation. To protect the cable, a protective tube is usually installed on the outside of the cable. Currently, when installing cable protective tubes, the cable needs to pass through the protective tube. However, the existing protective tubes are not removable, which is inconvenient when connecting cables in series.

[0003] A search revealed a utility model patent with publication number CN213521133U, which discloses a cable protection pipe with a built-in anti-corrosion protective wall. The pipe comprises two symmetrically arranged half-pipes, each with a protective layer on its inner wall. Two parallel connecting brackets are tightly bonded to each half-pipe. This cable protection pipe with a built-in anti-corrosion protective wall effectively prevents corrosion and protects the cable. The connecting brackets and fixing components connect the two half-pipes and fix them in place. The connection is convenient thanks to the cooperation of threaded rods and sliders. Therefore, when installing cables, the cable can be passed through the lower half-pipe first before installing the other two half-pipes. This design facilitates the installation of the protective pipe on the outside of the cable and is quick and easy.

[0004] The aforementioned patent, through its protective layer alone, effectively prevents corrosion and protects the cable. However, the connecting frame and fixing components, which connect the two half-pipes and secure them with the help of threaded rods and sliders, make the connection relatively convenient. This approach fails to adequately address the problems of pipe rupture and interface displacement that can easily occur in underground pipeline systems under complex geological environments or external loads due to overly simplified structural designs. These issues severely impact the normal use of cables. Furthermore, the overly simplistic waterproofing structure makes it prone to water accumulation, compromising cable lifespan.

[0005] Therefore, it is necessary to invent a corrosion-resistant cable protection pipe to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a corrosion-resistant cable protection pipe. It protects the cable through an upper pipe, a lower pipe, and an insulating protective layer, improving the safety factor of cable use. The addition of reinforcing ribs and supporting inclined plates enhances the compressive strength of the protective pipe structure, reducing the possibility of deformation. Furthermore, the internal support of the pipe body is made hollow by the reinforcing ribs and supporting inclined plates, significantly reducing the pipe's weight. A fireproof layer is filled inside the hollow structure to effectively limit cable fires, improving structural safety. This addresses the problems in existing underground pipeline systems where overly simplified structural designs lead to pipe rupture and interface displacement under complex geological environments or external loads, severely affecting cable use. Additionally, the overly simple waterproof structure allows for water accumulation, compromising cable lifespan.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant cable protection pipe, comprising an upper pipe and a lower pipe, wherein the upper pipe is located above the lower pipe, and a splicing edge 1 is fixedly connected to the bottom of both sides of the inner wall of the upper pipe, and a positioning strip is fixedly connected to the bottom of the splicing edge 1. A splicing edge 2 is fixedly connected to the top of both sides of the inner wall of the lower pipe, and a positioning groove matching the positioning strip is provided on the splicing edge 2. An insulating protective layer is fixedly connected between the two splicing edges 1 and splicing edges 2, and a guide groove is symmetrically provided in the middle of the insulating protective layer.

[0008] Preferably, an electromagnetic shielding layer is fixedly installed inside both the upper and lower half-pipes. A reinforcing rib is fixedly connected between the electromagnetic shielding layer and the interior of the upper and lower half-pipes. The number of reinforcing ribs is set to multiple, and the multiple reinforcing ribs are arranged in a ring array about the center point of the upper and lower half-pipes. A supporting inclined plate is fixedly connected between two adjacent reinforcing ribs, and a fireproof layer is filled between the supporting inclined plate and the reinforcing rib.

[0009] Preferably, both ends of the upper and lower pipes are fixedly connected with waterproof flanges.

[0010] Preferably, mounting brackets are symmetrically welded on both the upper and lower halves of the tube, and a fixing block is detachably connected between two adjacent mounting brackets by fixing screws. Positioning blocks are fixedly connected to the top and bottom of the fixing blocks.

[0011] Preferably, the mounting bracket has a fixing hole on its side that matches the fixing screw.

[0012] Preferably, the end of the mounting bracket is provided with a slot that matches the positioning block.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. The cable is protected by an upper half-pipe, a lower half-pipe, and an insulation protective layer, which improves the safety factor of the cable. The addition of reinforcing ribs and supporting inclined plates enhances the compressive strength of the protective pipe structure composed of the upper and lower half-pipes, reducing the possibility of deformation. Furthermore, the internal support of the pipe body is made into a hollow structure by reinforcing ribs and supporting inclined plates, which greatly reduces the weight of the pipe body. A fireproof layer is filled inside the hollow structure to effectively limit the cable fire and improve the safety of the structure.

[0015] 2. The insertion and cooperation of the positioning strip and the positioning groove can achieve a good waterproof effect at the connection between the upper and lower pipes, preventing external water stains from entering the interior and protecting the cable. The drainage groove can guide the internal water to avoid accumulation and extend the cable's life. Combined with the waterproof edge, it greatly reduces the phenomenon of fluid intrusion through the two ends of the pipe body, improving structural safety. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The diagram shows a corrosion-resistant cable protection pipe, comprising an upper pipe 1 and a lower pipe 2. The upper pipe 1 is positioned above the lower pipe 2. A splicing edge 3 is fixedly connected to the bottom of both sides of the inner wall of the upper pipe 1, and a positioning strip 4 is fixedly connected to the bottom of the splicing edge 3. A splicing edge 2 5 is fixedly connected to the top of both sides of the inner wall of the lower pipe 2. A positioning groove 6 matching the positioning strip 4 is provided on the splicing edge 2 5. The splicing edge 1 3 and the upper pipe 1 are integrally formed, and the splicing edge 2 5 and the lower pipe 2 are integrally formed. The insertion and connection of the positioning strip 4 and the positioning groove 6 provides good waterproofing, preventing external water stains from entering the upper pipe 1 and the lower pipe 2, thus protecting the cable. The upper pipe 1 and the lower pipe 2 are made of PVC material, which has the advantages of light weight, corrosion resistance, and high pressure resistance, making it suitable as a cable protection pipe.

[0026] An insulating protective layer 7 is fixedly connected between the two splicing edges 3 and the splicing edge 5. The insulating protective layer 7 is made of polyurethane anti-corrosion coating. The polyurethane anti-corrosion coating can play a good anti-corrosion role and can protect the cable placed inside.

[0027] The insulating protective layer 7 has symmetrically opened guide grooves 8 in the middle. The guide grooves 8 can guide the fluid accumulated in the upper pipe 1 to the openings at both ends of the upper pipe 1 and the lower pipe 2, so as to avoid accumulation in the upper pipe 1 and the lower pipe 2.

[0028] Both the upper tube 1 and the lower tube 2 are fixedly equipped with an electromagnetic shielding layer 9. The electromagnetic shielding layer 9 can enhance the protection of the cables placed inside the upper tube 1 and the lower tube 2.

[0029] The electromagnetic shielding layer 9 is fixedly connected to the interior of the upper half-pipe 1 and the lower half-pipe 2 by reinforcing ribs 10. The number of reinforcing ribs 10 is set to multiple, and the multiple reinforcing ribs 10 are arranged in a ring array about the center point of the upper half-pipe 1 and the lower half-pipe 2. A supporting inclined plate 11 is fixedly connected between two adjacent reinforcing ribs 10. A fireproof layer 12 is filled between the supporting inclined plate 11 and the reinforcing rib 10. The supporting inclined plate 11 and the reinforcing rib 10 work together to enhance the overall structural strength of the upper half-pipe 1 and the lower half-pipe 2. Due to the uniform distribution of the structure, it can promote the uniform external force on the upper half-pipe 1 and the lower half-pipe 2, while greatly improving the compressive strength. The fireproof layer 12 can effectively limit the cable fire.

[0030] Both ends of the upper pipe 1 and the lower pipe 2 are fixedly connected with waterproof flanges 13. The waterproof flanges 13 are set at the opening of the pipe body to reduce the possibility of rainwater flowing into the inside of the pipe body.

[0031] Mounting brackets 14 are symmetrically welded on both the upper half-pipe 1 and the lower half-pipe 2. A fixing block 16 is detachably connected between two adjacent mounting brackets 14 by fixing screws 15.

[0032] Positioning blocks 17 are fixedly connected to both the top and bottom of the fixing block 16.

[0033] The mounting bracket 14 has mounting holes 19 on its side that match the fixing screws 15.

[0034] The end of the mounting bracket 14 is provided with a slot 18 that matches the positioning block 17. By pre-inserting the positioning block 17 into the slot 18 and then connecting it with the threaded installation of the fixing screw 15 and the fixing hole 19, the tightness of the two mounting brackets 14 can be improved, and the misalignment caused by gaps can be avoided, which would affect the stability of the tube assembly.

[0035] The working principle of this practical application is as follows:

[0036] The user first passes the cable through the lower half-pipe 2. Then, the user inserts the positioning block 17 located at the bottom of the fixing block 16 into the corresponding slot 18 on the lower half-pipe 2. The user then places the upper half-pipe 1 aligned with the lower half-pipe 2. At the same time, the user aligns the slot 18 in the mounting bracket 14 on the upper half-pipe 1 with the positioning block 17 above the fixing block 16 and inserts it. Once the fixing block 16 is in place, the two mounting brackets 14 are connected. The user then rotates the fixing screw 15 and inserts it into the fixing hole 19 to achieve a fixed connection between the upper half-pipe 1 and the lower half-pipe 2.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
