Description

Technical Field

[0001] The utility model relates to the technical field of cable tubes, in particular to a CPVC power cable protection tube. Background Art

[0002] CPVC power pipe is usually used as a cable protection pipe. The cable protection pipe refers to a metal protection pipe with a certain mechanical strength and laid on the outer layer of the cable to prevent the cable from being damaged.

[0003] The cable protection tube in the related art is generally buried underground. Since the cable protection tube buried underground is easy to be drilled by termites, the structural strength of the cable protection tube is reduced, which easily causes rainwater to penetrate into the cable protection tube, which easily causes damage to the cable and affects the normal operation of the cable.

[0004] The existing patent (publication number: CN218040570U) is a CPVC power cable protection tube, which relates to the field of cable tubes. It includes an inner tube and a reinforcement tube sleeved on the inner tube. A protective layer, an insect repellent layer and an anti-cracking reinforcement layer are arranged in sequence between the relative tube walls of the reinforcement tube and the inner tube. The insect repellent layer includes a plurality of air bags filled with an insect repellent gel layer. This application has the effect of helping to prevent termites from biting the cable protection tube and enhancing the structural strength of the cable protection tube.

[0005] In view of the above problems, the existing patent provides a solution, but the patent only has the function of preventing insects and cannot cope with the functions of cable noise, cable bending and multiple cable protection.

[0006] Therefore, a CPVC power cable protection tube is proposed. Summary of the invention

[0009] Preferably, the material of the silent cotton is porous fiber silent cotton, which has good sound absorption performance. When sound waves contact the silent cotton, the sound waves will be absorbed by the silent cotton and converted into heat energy, thereby achieving the effect of reducing noise.

[0010] Preferably, the explosion-proof layer is made of polytetrafluoroethylene, which has excellent high temperature resistance, corrosion resistance and aging resistance, and can maintain stable performance under high temperature and high pressure environments.

[0011] Preferably, the reinforcing layer is made of glass fiber, which has excellent properties such as high strength, high elastic modulus, low density, high temperature resistance, corrosion resistance, and insulation, and can significantly improve the strength, rigidity, fatigue resistance, and corrosion resistance of the composite material.

[0012] Preferably, the adhesive layer is made of epoxy resin, which enhances the bonding force between the layers, ensures the overall stability of the pipe, and provides additional protection and support for the base layer.

[0013] Preferably, the base layer is made of CPVC material, which provides basic electrical insulation performance and is combined with other reinforcement material layers to provide the required physical properties.

[0014] Preferably, the plastic layer is made of plastic to protect the cable surface from wear and tear.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 , the utility model provides a technical solution:

[0028] A CPVC power cable protection tube comprises an outer tube 1, a partition 2 is arranged inside the outer tube 1, a silent cotton 3 is arranged on one side of the partition 2, an explosion-proof layer 4 is arranged on the inner side of the outer tube 1, a reinforcing layer 5 is arranged on the inner side of the explosion-proof layer 4, an adhesive layer 6 is arranged inside the reinforcing layer 5, a base layer 7 is arranged on the inner side of the adhesive layer 6, and a plastic layer 8 is arranged on the inner side of the base layer 7.

[0029] The outer tube 1 is used for basic support, and the noise of the cable is absorbed by the sound-absorbing cotton. The explosion-proof layer 4 can release the pressure in time when the pressure inside the pipe is too high to avoid explosion or rupture of the pipe. The reinforcement layer 5 can add a layer of glass fiber reinforcement layer 5 to improve the strength and rigidity of the pipe, which can effectively reduce the deformation and damage of the pipe when subjected to external force. The adhesive layer 6 supports the base layer 7 on the one hand, and enhances the adhesion between the base layer 7 and the reinforcement layer 5 on the other hand. The base layer 7 is supported by the plastic layer 8 and cooperates with the outer tube 1 to support all layers. The plastic layer 8 is on the side close to the cable, mainly to reduce wear on the cable surface.

[0030] Specifically, Figure 1 As shown, the material of the silent cotton 3 is porous fiber silent cotton 3, which has good sound absorption performance. When the sound waves contact the silent cotton 3, the sound waves will be absorbed by the silent cotton 3 and converted into heat energy, thereby achieving the effect of reducing noise.

[0031] By setting the silent cotton 3 made of porous fiber sound-absorbing cotton material, the effect of absorbing noise can be achieved. The characteristic of the porous fiber silent cotton 3 is that there are a large number of tiny holes inside the material. These holes can absorb sound wave energy and convert it into heat energy, thereby achieving the purpose of noise reduction. In addition, the porous fiber silent cotton 3 also has good moisture absorption and moisture-proof properties, and can effectively absorb moisture in the air to prevent the influence of moisture on the sound insulation effect.

[0032] Specifically, Figure 3 As shown, the material of the explosion-proof layer 4 is polytetrafluoroethylene, which has excellent high temperature resistance, corrosion resistance and aging resistance, and can maintain stable performance under high temperature and high pressure environment.

[0033] By setting the explosion-proof layer 4 made of polytetrafluoroethylene, the rupture and bending forces inside the pipeline can be absorbed. Polytetrafluoroethylene (PTFE) is a synthetic polymer formed by the polymerization of tetrafluoroethylene. Since the fluorine atoms in its molecular structure occupy the position between the carbon-hydrogen atoms, polytetrafluoroethylene has many excellent properties, such as high temperature resistance, corrosion resistance, non-stickiness, insulation, low friction coefficient, etc.

[0034] Specifically, Figure 5 As shown, the reinforcing layer 5 is made of glass fiber, which has excellent properties such as high strength, high elastic modulus, low density, high temperature resistance, corrosion resistance, and insulation, and can significantly improve the strength, rigidity, fatigue resistance, and corrosion resistance of the composite material.

[0035] By providing a reinforcing layer 5 made of glass fiber material, the supporting strength inside the outer tube 1 can be increased. The advantages of glass fiber include good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, etc. It can withstand high temperature and chemical corrosion, and has high strength and wear resistance.

[0036] Specifically, Figure 5 As shown, the material of the adhesive layer 6 is epoxy resin, which enhances the bonding force between the layers, ensures the overall stability of the pipe, and provides additional protection and support for the base layer 7.

[0037] By setting an explosion-proof layer 4 made of polytetrafluoroethylene material.

[0038] Specifically, Figure 1 As shown, the base layer 7 is made of CPVC material, which provides basic electrical insulation performance and is combined with other reinforcement material layers to provide required physical properties.

[0039] By providing a base layer 7 of epoxy resin material, basic strength can be provided for the interior of the outer tube 1. The advantages of epoxy resin include strong adhesion, small shrinkage, good stability, strong corrosion resistance, etc. It can form strong adhesion with the surfaces of various materials and has a small shrinkage, which is beneficial to improving the dimensional accuracy and stability of the product.

[0040] Specifically, Figure 1 As shown, the plastic layer 8 is made of plastic to protect the cable surface from wear and tear.

[0041] The surface of the cable can be protected from being scratched by providing the plastic layer 8. Advantages of plastic products include light weight, high strength, good insulation, strong corrosion resistance, etc.

[0042] Specifically, Figure 4 As shown, an anti-wear portion 9 is provided on the outer side of the outer tube 1 , and both the anti-wear portion 9 and the outer tube 1 are made of PVC material.

[0043] By providing the anti-wear portion 9 made of PVC material, the surface of the outer tube 1 can have an anti-wear effect.

[0044] By adopting the above technical solution, the problem that the existing CPVC power pipe usually only has the function of insect prevention and cannot cope with the cable noise, cable bending and cable multiple protection functions is solved.

[0045] Working principle: When the present application is in use, first, the outer tube 1 is used for basic support, and the noise of the cable is absorbed by the sound-absorbing cotton. The explosion-proof layer 4 can release the pressure in time when the pressure inside the pipe is too high to avoid explosion or rupture of the pipe. The reinforcement layer 5 can add a layer of glass fiber reinforcement layer 5 to improve the strength and rigidity of the pipe, which can effectively reduce the deformation and damage of the pipe when subjected to external force. The adhesive layer 6 supports the base layer 7 on the one hand, and enhances the adhesion between the base layer 7 and the reinforcement layer 5 on the other hand. The base layer 7 is supported by the plastic layer 8 and the outer tube 1 cooperates to support all the layers. The plastic layer 8 is on the side close to the cable, which mainly reduces the wear on the cable surface. By setting the anti-wear part 9, the surface of the outer tube 1 can have an anti-wear effect.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
