Description

Technical Field

[0001] This utility model relates to the field of corrugated pipes, and more particularly to cold-resistant and wear-resistant carbon corrugated pipes. Background Technology

[0002] Carbon corrugated pipe is a new type of power cable protection pipe made of chemical HDPE high-density polyethylene resin as the main material and modified carbon and other auxiliary materials. It is extruded through a special process and has excellent chemical properties, including insulation, pressure resistance, good toughness and acid and alkali corrosion resistance. This pipe is suitable for the protection of power cables. Its flexibility allows it to bend freely when encountering obstacles, which is convenient for construction.

[0003] Existing corrugated pipes lack a limiting structure during use, making it impossible to limit the bending position of the corrugated pipe after installation. As a result, the corrugated pipe is prone to springback due to its own material structure after installation, leading to the problem of misalignment of the installation position.

[0004] Therefore, to address the issue that existing corrugated pipes lack a limiting structure during use, making it impossible to limit the bending position after installation and causing the pipe to easily spring back, a cold-resistant and wear-resistant carbon corrugated pipe can be designed. By setting a first hook, a connecting rod, and a second hook, the corrugated pipe body will usually bend at a certain angle after installation. After bending, the first hook and the second hook at both ends of the connecting rod can be hung on suitable mounting seats respectively. The setting of the first connecting ring, the first hinge seat, the second connecting ring, and the second hinge seat facilitates the rotation and adjustment of the entire limiting structure, thereby facilitating installation and limiting the bending position of the corrugated pipe body to prevent springback. Utility Model Content

[0005] In order to overcome the problem that existing corrugated pipes do not have a limiting structure during use, and cannot limit the bending position of the corrugated pipe after installation, resulting in the corrugated pipe easily springing back after installation.

[0006] The technical solution of this utility model is as follows: a cold-resistant and wear-resistant carbon corrugated pipe, including a corrugated pipe body; it also includes a mounting base, a connecting hole, a first hook, a first connecting ring, a first hinge seat, a connecting rod, a second hinge seat, a second connecting ring, and a second hook. Multiple mounting bases are evenly spaced at the concave position on the lower side of the outer surface of the corrugated pipe body. Each mounting base has a connecting hole extending through it at the lower front surface. The foremost mounting base is connected to a first hook through the connecting hole. A first connecting ring is mounted at the bottom of the first hook. A first hinge seat is connected at the bottom of the first connecting ring. A connecting rod is located at the bottom of the first hinge seat. A second hinge seat is mounted at the bottom of the connecting rod. A second connecting ring is located at the bottom of the second hinge seat. A second hook is connected at the bottom of the second connecting ring.

[0007] Preferably, by setting a first hook, a connecting rod, and a second hook, the corrugated pipe body will usually bend at a certain angle after installation. After bending, the first hook and the second hook at both ends of the connecting rod can be hung on suitable mounting seats respectively. The setting of the first connecting ring, the first hinge seat, the second connecting ring, and the second hinge seat can facilitate the rotation and adjustment of the entire limiting structure, thereby facilitating installation. This limits the bending position of the corrugated pipe body and avoids the problem of springback. This solves the problem that existing corrugated pipes do not have a limiting structure when in use, and cannot limit the bending position of the corrugated pipe after installation, which leads to the problem of springback of the corrugated pipe after installation.

[0008] Preferably, the outer surface of the corrugated pipe body is coated with an acrylic polyurethane topcoat.

[0009] Preferably, the inner surface of the corrugated pipe body is coated with epoxy resin paint.

[0010] Preferably, the inner surface of the corrugated pipe body is provided with an insulation layer, which is made of rock wool.

[0011] Preferably, connecting seats are provided at both the front and rear ends of the corrugated pipe body, and connecting pipes are provided on the side surface of the connecting seats away from the corrugated pipe body.

[0012] Preferably, both the first connecting ring and the second connecting ring are made of rubber.

[0013] Preferably, the first hinge seat, the second hinge seat, and the connecting rod are fixed together by welding.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a first hook, a connecting rod, and a second hook, the corrugated pipe body will usually bend at a certain angle after installation. After bending, the first hook and the second hook at both ends of the connecting rod can be hung on the appropriate mounting base respectively. The setting of the first connecting ring, the first hinge base, the second connecting ring, and the second hinge base can facilitate the rotation and adjustment of the entire limiting structure, thereby facilitating installation. This limits the bending position of the corrugated pipe body and avoids the problem of springback. This solves the problem that existing corrugated pipes do not have a limiting structure when in use, and cannot limit the bending position of the corrugated pipe after installation, which leads to the problem of springback after installation.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a cold-resistant and wear-resistant carbon corrugated pipe, including a corrugated pipe body 1; it also includes a mounting base 2, a connecting hole 3, a first hook 4, a first connecting ring 5, a first hinge seat 6, a connecting rod 7, a second hinge seat 9, a second connecting ring 10, and a second hook 11. Multiple mounting bases 2 are evenly spaced at the recessed position on the lower side of the outer surface of the corrugated pipe body 1. A connecting hole 3 is provided through the lower part of the front surface of each mounting base 2. The foremost mounting base 2 is connected to the first hook 4 through the connecting hole 3. The bottom end of the first hook 4 is fitted with the first connecting ring 5, and the bottom end of the first connecting ring 5 is connected to the first hinge seat 6. A connecting rod 7 is provided at the bottom of the first hinge seat 6. A second hinge seat 9 is installed at the bottom of the connecting rod 7. A second connecting ring 10 is provided at the bottom of the second hinge seat 9. A second hook 11 is connected to the bottom end of the second connecting ring 10. By setting the first hook 4, the connecting rod 7, and the second hook 11, the bellows body 1 will usually bend at a certain angle after installation. After bending, the first hook 4 and the second hook 11 at both ends of the connecting rod 7 can be hung on the appropriate mounting seat 2 respectively. The setting of the first connecting ring 5, the first hinge seat 6, the second connecting ring 10, and the second hinge seat 9 can facilitate the rotation and adjustment of the entire limiting structure, thereby facilitating installation. This limits the bending position of the bellows body 1 and prevents it from springing back.

[0023] Please see Figures 1-4In this embodiment, the outer surface of the corrugated pipe body 1 is coated with acrylic polyurethane topcoat. By coating the outer surface of the corrugated pipe body 1 with acrylic polyurethane topcoat, the corrugated pipe body 1 can have high wear resistance, solvent resistance, alkali resistance and other characteristics, and is suitable for various environments. The inner surface of the corrugated pipe body 1 is coated with epoxy resin paint. By coating the inner surface of the corrugated pipe body 1 with epoxy resin paint, the corrugated pipe body 1 can have good weather resistance, heat resistance, low temperature resistance, chemical resistance and other properties, and is suitable for installation in cold environments. The inner surface of the corrugated pipe body 1 is provided with a heat insulation layer 8, which is made of rock wool. By providing a heat insulation layer 8 made of rock wool, the cold resistance and heat insulation effect of the corrugated pipe body 1 can be improved, and the corrugated pipe body 1 can be prevented from cracking due to excessively low temperature.

[0024] Please see Figures 1-4 In this embodiment, connecting seats 12 are provided at both the front and rear ends of the corrugated pipe body 1. A connecting pipe 13 is provided on the side surface of the connecting seat 12 away from the corrugated pipe body 1. By providing connecting seats 12 and connecting pipes 13, it is convenient for workers to install and connect the corrugated pipe body 1 with external pipes, thus improving installation efficiency. The first connecting ring 5 and the second connecting ring 10 are both made of rubber. By using rubber materials for the first connecting ring 5 and the second connecting ring 10, the first connecting ring 5 and the second connecting ring 10 can have a certain elasticity and extensibility, so that the first hook 4 and the second hook 11 can be easily hung inside the corresponding connecting hole 3. The first hinge seat 6, the second hinge seat 9 and the connecting rod 7 are fixed by welding. By fixing the first hinge seat 6, the second hinge seat 9 and the connecting rod 7 by welding, the fixing strength between the three can be improved, and the problem of the first hinge seat 6 or the second hinge seat 9 falling off due to the long-term tensile force on both ends of the connecting rod 7 can be avoided.

[0025] During operation, spraying an acrylic polyurethane topcoat onto the outer surface of the corrugated pipe body 1 gives it high wear resistance, solvent resistance, and alkali resistance, making it suitable for various environments. Spraying an epoxy resin paint onto the inner surface of the corrugated pipe body 1 provides it with good weather resistance, heat resistance, low-temperature resistance, and chemical resistance, making it suitable for installation in cold environments. The addition of a rock wool insulation layer 8 improves the cold-resistant insulation effect of the corrugated pipe body 1, preventing it from cracking due to excessively low temperatures. The connection seat 12 and the connecting pipe 13 further enhance the connection. This facilitates the installation and connection of the corrugated pipe body 1 with the external pipe, improving installation efficiency. By using rubber materials for the first connecting ring 5 and the second connecting ring 10, the first connecting ring 5 and the second connecting ring 10 can have a certain elasticity and extensibility, making it easy to hang the first hook 4 and the second hook 11 inside the corresponding connecting hole 3. By using welding to fix the first hinge seat 6, the second hinge seat 9 and the connecting rod 7, the fixing strength between the three can be improved, avoiding the problem of the first hinge seat 6 or the second hinge seat 9 falling off due to the long-term tensile force on both ends of the connecting rod 7.

[0026] Through the above steps, by setting the first hook 4, connecting rod 7, and second hook 11, the corrugated pipe body 1 will usually bend at a certain angle after installation. After bending, the first hook 4 and the second hook 11 at both ends of the connecting rod 7 can be hung on the appropriate mounting base 2 respectively. The setting of the first connecting ring 5, the first hinge base 6, the second connecting ring 10, and the second hinge base 9 can facilitate the rotation and adjustment of the entire limiting structure, thereby facilitating installation. This limits the bending position of the corrugated pipe body 1 and avoids the problem of springback. This solves the problem that existing corrugated pipes do not have a limiting structure when in use, and cannot limit the bending position of the corrugated pipe after installation, which leads to the problem of springback of the corrugated pipe after installation.
