Description

Technical Field

[0001] This utility model belongs to the field of protective pipes, specifically relating to a high-strength cable protective pipe. Background Technology

[0002] Cable protection pipes are protective conduits with a certain mechanical strength, laid around the outer layer of cables to prevent damage. They are mainly installed where communication cables and power lines cross, primarily underground or on the surface, to protect cables from corrosion and damage, and to prevent short circuits caused by power line breaks. Cable protection pipes are commonly used in various environments, including underwater, snowy, saline-alkali environments, and urban underground power grid installations. However, when cable protection pipes are subjected to external pressure and deformation, the outer pipe can easily collapse, causing direct contact between the outer and inner pipes. This reduces the pressure resistance of the CPVC cable protection pipe, hindering its long-term use. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A high-strength cable protection tube includes a first inner tube and a first outer tube. The first inner tube is disposed inside the first outer tube. The outer side wall of the first inner tube is provided with a plurality of first support grooves, and the inner side wall of the first outer tube is provided with a plurality of second support grooves. The first support grooves and the second support grooves correspond one-to-one. A first support tube is disposed in the first support grooves and the second support grooves. The first inner tube, the first outer tube, and the first support tubes form a plurality of first elastic cavities. A first support plate is disposed in the first elastic cavity. The two ends of the first support plate are respectively hinged to the adjacent first support tubes.

[0006] Furthermore, the first support plate has a first arched portion that protrudes towards the first outer tube in the middle, and the inner wall of the first outer tube has a plurality of first grooves, each corresponding to one of the first arched portions.

[0007] Furthermore, a plurality of first support columns are provided on the outer side wall of the first inner tube, and a first arc surface is provided on the outer side of the first support column, and the first arc surface corresponds one-to-one with the first arched part.

[0019] Preferred embodiment.

[0020] This embodiment provides a high-strength cable protection pipe, including a first inner tube 20 and a first outer tube 10. The first inner tube 20 is disposed inside the first outer tube 10. The outer side wall of the first inner tube 20 is provided with a plurality of first support grooves 21, and the inner side wall of the first outer tube 10 is provided with a plurality of second support grooves 11. The first support grooves 21 and the second support grooves 11 correspond one-to-one. A first support tube 30 is disposed in the first support grooves 21 and the second support grooves 11. The first inner tube 20, the first outer tube 10 and the first support tube 30 form a plurality of first elastic cavities 40. A first support plate 31 is disposed in the first elastic cavity 40. The two ends of the first support plate 31 are respectively hinged to the adjacent first support tube 30.

[0021] Furthermore, the first support plate 31 has a first arched portion 32 that protrudes towards the first outer tube 10 in the middle, and the inner sidewall of the first outer tube 10 has a plurality of first grooves 12, which correspond one-to-one with the first arched portion 32.

[0022] Furthermore, a plurality of first support columns 22 are provided on the outer side wall of the first inner tube 20, and a first arc surface 26 is provided on the outer side of the first support column 22, and the first arc surface 26 corresponds one-to-one with the first arched part 32.

[0023] Furthermore, the inner wall of the first inner tube 20 is provided with a plurality of first reinforcing grooves 23, and the first reinforcing grooves 23 correspond one-to-one with the first support column 22.

[0024] Furthermore, the first reinforcing groove 23 is provided with a plurality of first rollers 24, and first rollers 25 are rolled on the first rollers 24.

[0025] Working principle: The first inner tube 20 is disposed inside the first outer tube 10. The cable passes through the first inner tube 20. The first roller 25 reduces the friction between the cable and the first inner tube 20, facilitating cable insertion. The first support tube 30 is disposed between the first inner tube 20 and the first outer tube 10, serving as a limit and support. When the first outer tube 10 is impacted, the first support tube 30 undergoes elastic deformation and disperses the pressure to both sides through the first support plate 31, thus protecting the cable. Simultaneously, the first support column 22 supports the first support plate 31 when no collision occurs, maintaining the relative stability of the cable protection tube. When a collision occurs, the first support plate 31 is affected by the deformation of the first support tube 30, causing it to flip to a certain extent. The first groove 12 limits excessive flipping of the first support plate 31, ensuring the deformation range of the first support tube 30 and guaranteeing the overall structural strength and stability. The first reinforcing groove 23 serves to increase the structural strength of the first inner tube 20 and also provides a location for the installation of the first roller 25.

[0026] It is worth mentioning that the technical features such as the first roller 25 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0027] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
