Description

Technical Field

[0001] This utility model belongs to the field of cable-related technology, specifically a power cable protection pipe. Background Technology

[0002] Power cable protection conduits are conduit systems specifically designed for laying and protecting power cables, typically made of high-performance materials such as CPVC, MPP, and HDPE. Like a "robust armor" for the cable, they are pre-installed underground, in tunnels, or within walls through methods such as direct burial, pipe jacking, or ductwork, providing a safe and stable physical passage for the core power transmission carrier cable. Their core function is to effectively resist multiple hazards such as groundwater, moisture, acid and alkali corrosion, microorganisms, accidental compression, and external mechanical impact, greatly extending the cable's service life and ensuring the reliability and stability of power transmission. They are an indispensable infrastructure in modern urban power grids, traffic lighting, and various engineering projects.

[0003] Patent document CN213585023U describes an MPP cable protection pipe, including a protection pipe body. The protection pipe body has a first connecting ring and a second connecting ring at both ends. The first connecting ring has a sealing block and several positioning pins, and the second connecting ring has a corresponding sealing groove and several positioning holes. Several mounting seats are symmetrically arranged on the first connecting ring. A lead screw is rotatably mounted on each mounting seat. A nut is threaded onto each lead screw. A connecting rod is hinged to each nut. A connecting block is fixedly connected to the end of each connecting rod. Each connecting block is engaged with a locking block. The locking blocks are all installed on the second connecting ring.

[0004] Existing power cable protection pipes have certain shortcomings in use. Traditional power cable protection pipes do not have a combined fixing structure. When laying cables, multiple cables usually need to be laid. The cable protection pipes cannot be arbitrarily adjusted according to the cable layout and number of cables, which reduces their flexibility in use. Secondly, the structural strength of traditional cable protection pipes is poor. The cable protection pipes only protect the cables through the pipe body structure. The cable protection pipes are prone to deformation under external pressure, which reduces their safety. In summary, existing power cable protection pipes do not have a combined fixing structure. When laying cables, multiple cables usually need to be laid. The cable protection pipes cannot be arbitrarily adjusted according to the cable layout and number of cables, which reduces their flexibility in use. Utility Model Content

[0005] This utility model provides a power cable protection pipe, which solves the problem that existing power cable protection pipes do not have a combined fixing structure. When laying cables, multiple cables are usually required, and the cable protection pipe cannot be arbitrarily adjusted according to the cable arrangement and number of cables, reducing its flexibility in use. A power cable protection pipe includes a pipe body and several sets of combined sleeves. The sets of combined sleeves are all fixedly sleeved on the outer surface of the pipe body and are evenly distributed between each set of combined sleeves. The inner side of each combined sleeve is provided with a fixing ring for use with the pipe body. The fixing ring is sleeved between the combined sleeve and the pipe body. The inner side of the pipe body is fixedly installed with a support part for use with the cable. The cross-section of the support part is a cross-shaped structure. Two sets of docking blocks are spliced ​​and installed on the outer side of the combined sleeve.

[0006] As a further technical solution of this utility model, the outer surface of the combined sleeve is provided with four sets of docking slots. The combined sleeve and the docking block are fixed together by docking slots. The four sets of docking slots are located at the top, bottom, left and right positions of the combined sleeve. When splicing and installing two sets of combined sleeves, the docking block can be locked in the docking slots of the two sets of combined sleeves to complete the splicing and fixing of the two sets of combined sleeves at any position. By connecting the combined sleeve to the pipe body, several sets of pipe bodies can be fixed together, which facilitates the protection installation of multiple sets of power cables.

[0007] As a further technical solution of this utility model, a limiting ring is fixedly installed on the inner side of one end of the combined sleeve to cooperate with the fixing ring. The inner diameter of the limiting ring is smaller than the outer diameter of the fixing ring. The setting of the fixing ring reinforces the installation of the pipe body and the combined sleeve. During operation, the fixing ring is first sleeved on the outer surface of the pipe body, and then the combined sleeve is sleeved on the pipe body. Pushing the combined sleeve causes it to squeeze the outer side of the fixing ring. At the same time, the limiting ring is used to limit and fix one end of the fixing ring, preventing the fixing ring from passing through the combined sleeve. The rubber fixing ring is deformed by the compression of the combined sleeve, so that the fixing ring is stuck between the combined sleeve and the pipe body, which reinforces the installation of the combined sleeve.

[0008] As a further technical solution of this utility model, the outer surface of the side of the fixing collar is inclined, and both the fixing collar and the combined sleeve are provided with a circular groove in the middle. The fixed collar with the inclined structure design can reduce the resistance when the combined sleeve is sleeved, and facilitate the docking operation between the combined sleeve and the fixing collar.

[0009] As a further technical solution of this utility model, a docking ring is provided on the outer surface of one end of the tube body, and the two tube bodies are fixed together by the docking ring. The docking ring plays the role of connecting the two tube bodies end to end.

[0010] As a further technical solution of this utility model, both ends of the docking ring are provided with arc-shaped portions, and the outer surface of the tube body is provided with arc-shaped grooves that cooperate with the arc-shaped portions. By using the arc-shaped portions to connect with the arc-shaped grooves, the docking and fixing between the tube body and the docking ring is completed.

[0011] As a further technical solution of this utility model, the end of the docking ring is provided with a beveled part on one side of the arc-shaped part. The arc-shaped part, the arc-shaped groove and the beveled part are all ring-shaped structures. The beveled part can reduce the resistance when the tube body and the docking ring are docked.

[0012] As a further technical solution of this utility model, the support part includes a horizontal support bar and a vertical support bar, which are perpendicular to each other. The support part is formed by extrusion. The cross-shaped support part is composed of a horizontal support bar and a vertical support bar. The support part is sleeved inside the tube body to form a cross-shaped partition support structure inside the tube body, which can improve the structural strength of the tube body and at the same time play a role in separating the cables inside the tube body, thereby improving the heat dissipation effect of the cables.

[0013] As a further technical solution of this utility model, the depth of the docking slot is half the thickness of the docking block, and the docking block is a rectangular block structure. The docking block can be used to dock two sets of docking slots.

[0014] As a further technical solution of this utility model, the ends of the horizontal and vertical support bars are both arc-shaped structures, and the ends of the horizontal and vertical support bars fit together with the inner wall of the pipe. The arc-shaped structure design allows the horizontal and vertical support bars to fit better with the inner wall of the pipe.

[0015] The beneficial effects of this utility model are as follows: By setting up a combination sleeve, this utility model provides a splicing and combination fixing structure for the power cable protection pipe. It can be arbitrarily combined according to the number and distribution of cables, improving its flexibility in use. During operation, the fixing ring is first fitted onto the outer surface of the pipe body, and then the combination sleeve is fitted onto the pipe body. Pushing the combination sleeve causes it to press against the outer side of the fixing ring. At the same time, the limiting ring is used to limit and fix one end of the fixing ring, preventing the fixing ring from passing through the combination sleeve and deforming the rubber fixing ring due to the compression of the combination sleeve. This causes the fixing ring to be stuck between the combination sleeve and the pipe body, which reinforces the installation of the combination sleeve. The four sets of docking slots are located at the top, bottom, left, and right positions of the combination sleeve. When splicing and installing two sets of combination sleeves, the docking blocks can be locked into the docking slots of the two sets of combination sleeves, completing the splicing and fixing of two sets of combination sleeves at any position. By fitting the combination sleeve onto the pipe body, several sets of pipe bodies can be combined and fixed, facilitating the protection installation of multiple sets of power cables. By incorporating a support section, the power cable protection pipe features a cross-shaped auxiliary support structure inside, enhancing its structural strength. The arc-shaped design allows the horizontal and vertical support bars to better conform to the inner wall of the pipe. The support section, formed by extrusion molding, consists of horizontal and vertical support bars. When fitted inside the pipe, it creates a cross-shaped partition support structure, improving the pipe's structural strength and simultaneously separating the cables within the pipe, allowing for separate storage of multiple cables and improving heat dissipation.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1-4 As shown, a power cable protection pipe includes a pipe body 1 and several sets of combined sleeves 2. The several sets of combined sleeves 2 are all fixedly sleeved on the outer surface of the pipe body 1. The several sets of combined sleeves 2 are distributed at equal intervals. The inner side of the combined sleeve 2 is provided with a fixing ring 9 for use with the pipe body 1. The fixing ring 9 is sleeved between the combined sleeve 2 and the pipe body 1. The inner side of the pipe body 1 is fixedly installed with a support part 5 for use with the cable 6. The cross-section of the support part 5 is a cross-shaped structure. Two sets of docking blocks 3 are spliced ​​and installed on the outer side of the combined sleeve 2.

[0021] The outer surface of the combination sleeve 2 is provided with four sets of docking slots 7. The combination sleeve 2 and the docking block 3 are fixed together by docking slots 7. The four sets of docking slots 7 are located at the top, bottom, left and right positions of the combination sleeve 2. When splicing and installing two sets of combination sleeves 2, the docking block 3 can be locked in the docking slots 7 of the two sets of combination sleeves 2 to complete the splicing and fixing of the two sets of combination sleeves 2 in any position. By connecting the combination sleeve 2 to the pipe body 1, several sets of pipe bodies 1 can be fixed together, which facilitates the protection installation of multiple sets of power cables.

[0022] A limiting ring 8 is fixedly installed on the inner side of one end of the combined sleeve 2 to cooperate with the fixing ring 9. The inner diameter of the limiting ring 8 is smaller than the outer diameter of the fixing ring 9. The setting of the fixing ring 9 plays a role in reinforcing the installation of the pipe body 1 and the combined sleeve 2. During operation, first, the fixing ring 9 is put on the outer surface of the pipe body 1, and then the combined sleeve 2 is put on the pipe body 1. Push the combined sleeve 2 so that the combined sleeve 2 squeezes the outer side of the fixing ring 9. At the same time, the limiting ring 8 is used to limit and fix one end of the fixing ring 9 to prevent the fixing ring 9 from passing through the combined sleeve 2. The rubber fixing ring 9 is deformed by the compression of the combined sleeve 2, so that the fixing ring 9 is stuck between the combined sleeve 2 and the pipe body 1, which plays a role in reinforcing the installation of the combined sleeve 2.

[0023] The outer surface of the fixed collar 9 is inclined, and both the fixed collar 9 and the combined sleeve 2 have a circular groove 10 in the middle. The fixed collar 9 with its inclined structure design can reduce the resistance when the combined sleeve 2 is fitted, and facilitate the docking operation between the combined sleeve 2 and the fixed collar 9.

[0024] A docking ring 4 is provided on the outer surface of one end of the tube body 1. The two tube bodies 1 are fixed together by the docking ring 4, which serves to connect the two tube bodies 1 end to end.

[0025] Both ends of the docking ring 4 are provided with arc-shaped parts 11, and the outer surface of the tube body 1 is provided with arc-shaped grooves 12 that are used to match the arc-shaped parts 11. The arc-shaped parts 11 are connected to the arc-shaped grooves 12 to complete the docking and fixing between the tube body 1 and the docking ring 4.

[0026] The end of the docking ring 4 is provided with a beveled part 13 on one side of the arc-shaped part 11. The arc-shaped part 11, the arc-shaped groove 12 and the beveled part 13 are all ring-shaped structures. The beveled part 13 can reduce the resistance when the tube body 1 and the docking ring 4 are docked.

[0027] The support part 5 includes a horizontal support bar 14 and a vertical support bar 15, which are perpendicular to each other. The support part 5 is formed by extrusion. The cross-shaped support part 5 is composed of the horizontal support bar 14 and the vertical support bar 15. The support part 5 is sleeved inside the tube body 1 to form a cross-shaped partition support structure inside the tube body 1, which can improve the structural strength of the tube body 1. At the same time, it can separate the cable 6 inside the tube body 1 and improve the heat dissipation effect of the cable 6.

[0028] The depth of the docking slot 7 is half the thickness of the docking block 3. The docking block 3 is a rectangular block structure. The docking slots 7 can be docked using the docking block 3.

[0029] The ends of the horizontal support bar 14 and the vertical support bar 15 are both arc-shaped structures. The ends of the horizontal support bar 14 and the vertical support bar 15 fit together with the inner wall of the pipe body 1. The arc-shaped structure design allows the horizontal support bar 14 and the vertical support bar 15 to fit better against the inner wall of the pipe body 1.

[0030] A power cable protection pipe, when in use, features a modular sleeve 2, providing a splicing and modular fixing structure. This allows for arbitrary combinations based on the number and distribution of cables, enhancing its flexibility. During operation, the fixing ring 9 is first fitted onto the outer surface of the pipe body 1, then the modular sleeve 2 is fitted onto the pipe body 1. Pushing the modular sleeve 2 causes it to press against the outer side of the fixing ring 9. Simultaneously, a limiting stop ring 8 limits and fixes one end of the fixing ring 9, preventing it from passing through the modular sleeve 2 and being subjected to its own force. The compression deforms the rubber retaining ring 9, causing it to lock between the combined sleeve 2 and the pipe body 1, thus reinforcing the installation of the combined sleeve 2. The four sets of docking slots 7 are located at the top, bottom, left, and right positions of the combined sleeve 2. When splicing two sets of combined sleeve 2, the docking block 3 can be locked in the docking slots 7 of the two sets of combined sleeve 2, completing the splicing and fixing of two sets of combined sleeve 2 in any position. By connecting the combined sleeve 2 to the pipe body 1, several sets of pipe bodies 1 can be fixed together, facilitating the protection installation of multiple sets of power cables. By setting the support part 5, the power cable protection pipe has a cross-shaped auxiliary support structure inside when in use, which improves the structural strength of the pipe body 1. First, the arc structure design allows the horizontal support bar 14 and the vertical support bar 15 to fit better against the inner wall of the pipe body 1. The support part 5 is formed by extrusion molding. The cross-shaped support part 5 is composed of the horizontal support bar 14 and the vertical support bar 15. The support part 5 is sleeved inside the pipe body 1 to form a cross-shaped partition support structure inside the pipe body 1, which can improve the structural strength of the pipe body 1. At the same time, it plays a role in separating the cables 6 inside the pipe body 1, allowing multiple cables 6 to be stored separately and improving the heat dissipation effect of the cables 6.

[0031] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
