Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, and in particular to a high wear-resistant power cable protection pipe. Background Technology

[0002] Cable protection pipes are protective conduits with a certain mechanical strength, laid on the outer layer of cables to prevent damage. They are mainly installed at intersections where communication cables and power lines cross to prevent short circuits caused by power line breaks. Cable protection pipes have a wide range of applications. In existing technology, the outer wall of cable protection pipes installed on the outside of low-altitude cables is easily worn during use, for example, by contact with external objects. Wear on the outer wall can cause damage or breakage of the cable protection pipe, leading to its failure and, in severe cases, damage to the cable itself. Therefore, the wear resistance of cable protection pipes is extremely important. Furthermore, existing cable protection pipes are generally tubular structures, making installation time-consuming and labor-intensive during cable insertion. Therefore, there is an urgent need for a more easily installed and wear-resistant cable protection pipe. Utility Model Content

[0003] The purpose of this invention is to provide a highly wear-resistant power cable protection pipe to solve the problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a high wear-resistant power cable protection pipe, comprising several sections of the protection pipe body. The protection pipe body includes a first arc-shaped plate and a second arc-shaped plate. One end of the first arc-shaped plate is rotatably connected to the second arc-shaped plate, and a connecting component is provided between the other end of the first arc-shaped plate and the second arc-shaped plate. Buffer meshes are fixedly connected to the inner walls of the first arc-shaped plate and the second arc-shaped plate, and the two buffer meshes form a cylindrical structure located around the cable. Several wear-resistant plates are detachably connected to the outer side of the protection pipe body.

[0005] Preferably, the connecting component includes a first arc-shaped groove formed in the first arc-shaped plate, an arc-shaped connecting plate slidably connected in the first arc-shaped groove, a compression spring fixedly connected between the arc-shaped connecting plate and the bottom wall of the first arc-shaped groove, and a second arc-shaped groove corresponding to the first arc-shaped groove, the length of the second arc-shaped groove being half the length of the arc-shaped connecting plate.

[0006] Preferably, a limiting groove is formed on the outer wall of the end of the arc-shaped connecting plate away from the compression spring, and through grooves are respectively formed on the first arc-shaped plate and the second arc-shaped plate corresponding to the limiting groove, and a limiting pin is detachably connected in the through groove.

[0007] Preferably, a plurality of limiting strips are fixedly connected to the periphery of the protective tube body. The plurality of limiting strips are arranged along the axial direction of the protective tube body. The cross-section of the limiting strip is T-shaped, and there is a gap between two adjacent limiting strips. The gap between two adjacent limiting strips and the outer wall of the protective tube body form an installation groove. The cross-section of the wear-resistant sheet is I-shaped. The bottom end of the wear-resistant sheet slides within the installation groove, and the top end of the limiting strip slides within the middle recess of the wear-resistant sheet.

[0008] Preferably, the wear-resistant sheet is a polyamide sheet.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figure 1-3 This utility model provides a high wear-resistant power cable protection pipe, comprising several sections of the protection pipe body. Each protection pipe body includes a first arc-shaped plate 1 and a second arc-shaped plate 2. One end of the first arc-shaped plate 1 is rotatably connected to the second arc-shaped plate 2, and a connecting component is provided between the other end of the first arc-shaped plate 1 and the second arc-shaped plate 2. Buffer mesh 3 is fixedly connected to the inner walls of the first arc-shaped plate 1 and the second arc-shaped plate 2, forming a cylindrical structure located around the cable. Several wear-resistant plates 4 are detachably connected to the outer side of the protection pipe body. By detachably providing several polyamide wear-resistant plates 4 on the outer side of the protection pipe body, the protection pipe body can be effectively protected, enhancing its overall wear resistance and thus better protecting the cable. Furthermore, this utility model sets the cable protection pipe into a segmented, split structure, and each section of the protection pipe body includes a rotatably mounted first arc-shaped plate 1 and a second arc-shaped plate 2. The first arc-shaped plate 1 and the second arc-shaped plate 2 are connected by a connecting component, making it easy to install at a designated location on the cable without the time-consuming and laborious process of threading the cable.

[0019] A further optimized solution includes a connecting component comprising a first arc-shaped groove 5 formed within a first arc-shaped plate 1, an arc-shaped connecting plate 6 slidably connected within the first arc-shaped groove 5, and a compression spring 7 fixedly connected between the arc-shaped connecting plate 6 and the bottom wall of the first arc-shaped groove 5. A second arc-shaped plate 2 has a second arc-shaped groove 8 corresponding to the first arc-shaped groove 5, the length of which is half the length of the arc-shaped connecting plate 6. The compression spring 7 moves one end of the arc-shaped connecting plate 6 into the second arc-shaped groove 8, while the other end of the arc-shaped connecting plate 6 remains within the first arc-shaped groove 5. Because the center of the arc-shaped connecting plate 6 is not aligned with the rotation center of the first arc-shaped plate 1, it limits the movement of the first arc-shaped plate 1 and the second arc-shaped plate 2, preventing them from separating and achieving connection.

[0020] To further optimize the design, a limiting groove 9 is formed on the outer wall of the arc-shaped connecting plate 6 away from the compression spring 7. Corresponding to the limiting groove 9, through grooves 10 are formed on the first arc-shaped plate 1 and the second arc-shaped plate 2, respectively. A limiting pin is detachably connected within each through groove 10. By engaging the limiting pin with the through groove 10 on the first arc-shaped plate 1, the arc-shaped connecting plate 6 can be stably secured within the first arc-shaped groove 5 before installation. The engaging pin with the through groove 10 on the second arc-shaped plate 2 ensures that one end of the arc-shaped connecting plate 6 is located within the second arc-shaped groove 8, guaranteeing the connection between the first arc-shaped plate 1 and the second arc-shaped plate 2.

[0021] Further optimization of the design involves fixing several limiting strips 11 around the periphery of the protective tube body. These limiting strips 11 are arranged along the axial direction of the protective tube body, and each limiting strip 11 has a T-shaped cross-section. A gap is left between adjacent limiting strips 11, and this gap, together with the outer wall of the protective tube body, forms an installation groove. The wear-resistant plate 4 has an I-shaped cross-section, with its bottom end sliding within the installation groove, and the top end of each limiting strip 11 sliding in the central recess of the wear-resistant plate 4. Through the cooperation of the wear-resistant plate 4 and the limiting strips 11, the wear-resistant plate 4 can be stably installed around the protective tube body, thereby protecting the protective tube body and enhancing its overall wear resistance.

[0022] Further optimization of the design: wear-resistant sheet 4 is now made of polyamide.

[0023] The design was further optimized so that the buffer mesh 3 is a mesh made of interwoven steel wires, and the cross-section of the buffer mesh 3 is semi-circular. The interwoven steel wire mesh can buffer external impacts, thereby protecting the internal cables.

[0024] The working process of this utility model is as follows: In use, firstly, the first arc plate 1 is attached to the designated position of the cable, then the second arc plate 2 is rotated to make the second arc plate 2 and the first arc plate 1 fasten together. Then, the limiting pin located on the first arc plate 1 is pulled out, and the arc connecting plate 6 moves into the second arc groove 8 under the action of the compression spring 7. Since the length of the arc connecting plate 6 is equal to that of the second arc groove 8, half of the arc connecting plate 6 is located in the second arc groove 8 and half is located in the first arc groove 5. Since the center of the arc connecting plate 6 is not the same as the rotation center of the first arc plate 1, the limiting is achieved, ensuring the connection between the first arc plate 1 and the second arc plate 2. Then, the limiting pin is inserted into the through groove 10 on the second arc plate 2. The limiting pin and the limiting groove 9 are used to limit the arc connecting plate 6. Then, the wear-resistant plate 4 is inserted between the limiting strips 11 to improve the wear resistance.
