Description

Technical Field

[0001] This utility model relates to the field of cable protection pipes, specifically to a cable protection pipe for cable protection. Background Technology

[0002] High-voltage power cables are important carriers for power and communication transmission. During the installation of high-voltage power cables, it is often necessary to install protective conduits around the cables to effectively protect them.

[0003] Existing cable protection pipes mostly use a single material, making it difficult to balance lightweight and high strength. Traditional protection pipes do not have an independent insulation layer and rely solely on the insulation of the base material itself, which is insufficient to meet the insulation requirements under high voltage environments. Furthermore, the installation openings lack effective shielding and sealing structures, allowing moisture to easily seep into the pipe body, leading to cable short circuits or corrosion. They also have poor waterproof sealing and are not convenient for quick snap-fit ​​installation. There is an urgent need to design a cable protection pipe for cable protection to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cable protection tube for cable protection, so as to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable protection conduit for cable protection includes a conduit body with an installation opening and a shielding portion corresponding to the installation opening. The conduit body comprises an insulation layer, a substrate, and a water-cured coating, which are stacked sequentially from the inside to the outside. A sealing layer is provided at the bottom of the shielding portion, corresponding to the insulation layer. A snap-fit ​​assembly is provided between the shielding portion and the installation opening.

[0007] Furthermore, the substrate is made of basalt filaments and glass fiber filaments, and the substrate is formed by plain weaving of basalt filaments and glass fiber filaments.

[0008] Furthermore, the water-curing coating is a waterproof and moisture-proof coating formed by a moisture-curing polyurethane adhesive, and the overall thickness of the water-curing coating is 3-5 mm.

[0009] Furthermore, one side of the installation opening and one end of the shielding part are both provided with a slope. The snap-fit ​​assembly includes an extension strip provided on the shielding part, a plurality of snap pins provided at the bottom of the extension strip, a positioning groove provided at the top of one side of the installation opening, and a plurality of slots opened at the top of the positioning groove. The extension strip corresponds to the positioning groove, and the plurality of snap pins respectively engage with the plurality of slots.

[0010] Furthermore, the insulating layer and the sealing layer are integrally connected, the insulating layer and the sealing layer are made of silicone rubber, and the insulating layer and the substrate are integrally formed by molding process.

[0011] Furthermore, one end of the insulating layer and one end of the sealing layer are both provided with an angle, and the angle at one end of the insulating layer abuts against the angle at one end of the sealing layer.

[0012] In the above technical solution, the cable protection tube for cable protection provided by this utility model has the following beneficial effects:

[0013] Through the design of the shielding part, insulation layer, substrate, water-curing coating and sealing layer, the water-curing coating and insulation layer form a double insulation barrier to effectively block current leakage. The shielding part and sealing layer, together with the insulation layer, reduce moisture penetration. The moisture-curing polyurethane adhesive cures in a humid environment to form a dense waterproof layer, preventing the substrate from absorbing moisture and expanding. The snap-fit ​​assembly allows for manual installation with its ring-clamp structure, facilitating quick snap-fit ​​fixing. The basalt fiber and glass fiber in the substrate are lightweight, reducing the weight of the protective tube body, making it convenient for transportation and installation while resisting external pressure and puncture.

[0020] 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.

[0021] like Figure 1-4 As shown in the figure, this utility model provides a cable protection tube for cable protection.

[0022] The device includes a protective tube body 1, which has an installation opening 2 and a shielding part 3, which corresponds to the installation opening 2. The protective tube body 1 includes an insulating layer 4, a substrate 5, and a water-cured coating 6, which are stacked sequentially from the inside to the outside. A sealing layer 7 is provided at the bottom of the shielding part 3, which corresponds to the insulating layer 4. A snap-fit ​​assembly 8 is provided between the shielding part 3 and the installation opening 2.

[0023] Reference Figure 4 In this embodiment, the substrate 5 is made of basalt filaments and glass fiber filaments, and is formed by plain weaving of basalt filaments and glass fiber filaments. Basalt filaments are a high-performance inorganic fiber material with high tensile strength, high elastic modulus and impact resistance, outstanding high temperature resistance, and can be completely degraded after use. Glass fiber filaments have high strength, corrosion resistance and insulation, and are mainly used as reinforcing materials.

[0024] Reference Figure 4 In this embodiment, the water-curing coating 6 is a waterproof and moisture-proof coating formed by a moisture-curing polyurethane adhesive, and the overall thickness of the water-curing coating 6 is 4mm. Moisture-curing polyurethane adhesives have the characteristic of rapid curing, curing quickly in humid environments without the need for additional heat sources or ultraviolet radiation. They are easy to operate and form a dense waterproof layer after curing, preventing the substrate from absorbing moisture and expanding.

[0025] Reference Figure 2In this embodiment, both one side of the installation opening 2 and one end of the shielding part 3 are provided with inclined surfaces 9. The snap-fit ​​assembly 8 includes an extension strip 10 provided on the shielding part 3, multiple snap fasteners 11 provided at the bottom of the extension strip 10, a positioning groove 12 provided at the top of one side of the installation opening 2, and multiple slots 13 opened at the top of the positioning groove 12. The extension strip 10 corresponds to the positioning groove 12, and the multiple snap fasteners 11 respectively engage with the multiple slots 13. Through the provided extension strip 10, the extension strip 10 can be positioned and correspond to the positioning groove 12, so that the inclined surface 9 on one side of the installation opening 2 corresponds to the inclined surface 9 at one end of the shielding part 3. At the same time, pressing the extension strip 10 can cause the multiple snap fasteners 11 to enter the corresponding multiple slots 13 for snap-fit ​​fixation, completing the splicing and sealing of the protective tube body 1, so that the protective tube body 1 protects the cable.

[0026] Reference Figure 3 In this embodiment, the insulating layer 4 and the sealing layer 7 are integrally connected. The insulating layer 4 and the sealing layer 7 are made of silicone rubber, and the insulating layer 4 and the substrate 5 are integrally molded by compression molding. The insulating layer 4 and the sealing layer 7 have the same thickness, typically 5 mm. Silicone rubber is an insulating material with excellent insulation properties, which can effectively isolate current, prevent leakage, and also has resistance to high and low temperatures, and can have a certain degree of elasticity at high temperatures.

[0027] Reference Figure 3 In this embodiment, both one end of the insulating layer 4 and one end of the sealing layer 7 are provided with an angled bevel 14, which abuts against the angled bevel 14 at one end of the insulating layer 4 and the angled bevel 14 at one end of the sealing layer 7. Through the mating fit of the angled bevel 14, a continuous insulating and sealing structure is formed, which is simple to connect and has better sealing performance.

[0028] Working principle: In use, the protective tube body 1 is first installed around the cable. The cable is installed through the installation opening 2 on the protective tube body 1, allowing the cable to enter the protective tube body 1 through the installation opening 2. During the installation process, the insulation layer 4 will adhere to the cable periphery, forming the first layer of insulation protection. The shielding part 3 is used to shield and seal the installation opening 2. The synergistic effect of the snap-fit ​​component 8 and the inclined surface 9 significantly improves the sealing performance. At the same time, the sealing layer 7 will cooperate with the insulation layer 4 to form a continuous insulating and sealing structure. The substrate 5 plays a protective and supporting role, with anti-compression and anti-puncture effects. The moisture-curing polyurethane adhesive will cure in a humid environment, enhancing the waterproof performance and preventing the substrate 5 from cracking.

[0029] This utility model embodiment provides another material combination for the substrate 5, which uses aramid yarn and basalt yarn in a 3:1 ratio of twill weave. Aramid yarn has higher strength and can reduce structural weight in aerospace materials, thus having the advantage of lightweighting. Aramid yarn has good adhesion to rubber and is used as an insulating material for electrical equipment.

[0030] 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.
