Description

Technical Field

[0001] This utility model relates to the technical field of power pipes, specifically a highly flexible power pipe. Background Technology

[0002] With the continuous advancement of materials science, manufacturing processes and other technologies, highly flexible power cables have seen significant improvements in their flexibility, wear resistance, bending resistance and interference resistance, and are able to adapt to more complex and harsh working environments.

[0003] For example, a highly flexible power cable with authorization announcement number "CN201237925Y" solves the problems of insulation and sheath material cracking and shortened service life of existing highly flexible power cables. This cable, through a soft composite structure using extremely fine copper wire strands and multiple strands in the conductor, exhibits even greater flexibility than Class 5 conductors, allowing for better flexibility in special mobile applications than previous power cables. The insulation and sheath materials used are low-smoke, halogen-free, and extremely low toxicity, with radiation resistance, high and low temperature resistance, and abrasion resistance. They effectively adapt to wide temperature variations, resist radiation, and withstand the photo-aging of high-intensity ultraviolet light, with minimal toxicity to humans. Considering that existing highly flexible power cables still have insufficient protective performance in extreme environments, especially in conditions of frequent bending and movement, they are prone to sheath cracking and shielding layer breakage, affecting the stability and safety of power transmission. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing high-flexibility power cables are prone to sheath cracking and shielding layer breakage under frequent bending and movement conditions, and to propose a high-flexibility power conduit.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highly flexible power pipe, comprising a conductive layer and an insulating layer, wherein the inner wall of the insulating layer is fixedly connected to the conductive layer, an inner nameplate is processed on the outer wall of the insulating layer, the outer wall of the insulating layer is fixedly connected to a plastic sheath, and a reinforcing mechanism is connected to the outer wall of the plastic sheath.

[0006] This design features a flexible assembly with an ultra-fine copper wire stranded into a conductive layer, and the outer nameplate is laser-engraved to ensure clear and durable markings, facilitating identification during installation and maintenance.

[0007] Preferably, the reinforcing mechanism includes a shielding layer, the outer wall of which is slidably connected to a plastic sheath, the outer wall of which is fixedly connected to the reinforcing layer, and the outer wall of the reinforcing layer is coated.

[0008] This enhancement mechanism employs a multi-layer composite structure design, significantly improving the tensile strength and bending resistance of the power tube. The shielding layer is made of tin-plated copper mesh, which effectively shields against low frequencies and ensures the stability of power transmission. The reinforcement layer uses an aramid fiber woven structure, and the carbon coating is a nanotube coating, which effectively shields against low frequencies and absorbs high frequencies.

[0009] Preferably, the inner side of the reinforcing layer is machined with a cavity, and the outer wall of the coating is connected to a protective mechanism.

[0010] This cavity design reduces the overall weight while maintaining the compressive strength of the tube.

[0011] Preferably, the protective mechanism includes a sheath layer, the inner wall of which is attached to the sheath layer, the inner wall of which is fixedly connected to the curtain cord, and the outer wall of which is machined with a spiral groove.

[0012] The sheath layer is made of wear-resistant rubber, and the spiral groove design on the surface enhances the bending flexibility and anti-slip performance of the tube. Cords are added inside the sheath layer to improve the external mechanical strength and flexibility.

[0013] Preferably, the surface of the sheath layer is machined with an outer nameplate.

[0014] The nameplate is made of weather-resistant material, which can withstand various harsh environmental conditions and can be quickly identified during maintenance.

[0015] The present invention proposes a highly flexible power pipe, which has the following advantages: through the multi-layer composite structure design of the reinforcing mechanism, the mechanical strength and durability of the power pipe are significantly improved. The reinforcing layer is woven from high-strength fiber material and combined with a specially designed cavity structure, which reduces weight while maintaining excellent pressure resistance. The protective mechanism is made of wear-resistant rubber material, and the spiral groove design on the surface not only enhances flexibility and can adapt to various complex working conditions, but also effectively reduces the risk of damage under frequent bending and movement conditions.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] Please see Figure 1-7 In this embodiment, a highly flexible power pipe includes a conductive layer 1 and an insulating layer 2. The inner wall of the insulating layer 2 is fixedly connected to the conductive layer 1. An inner nameplate 3 is processed on the outer wall of the insulating layer 2. The outer wall of the insulating layer 2 is fixedly connected to a plastic sheath 4. A reinforcing mechanism 5 is connected to the outer wall of the plastic sheath 4.

[0026] The reinforcing mechanism 5 includes a shielding layer 501, the outer wall of which is slidably connected to the plastic sheath 4, and the outer wall of the shielding layer 501 is fixedly connected to the reinforcing layer 502. The outer wall of the reinforcing layer 502 is coated with a coating 503.

[0027] The multi-layer composite structure design of the reinforcing mechanism 5 significantly improves the mechanical strength and durability of the power pipe. The reinforcing layer 502 is woven from high-strength fiber material and has a specially designed cavity structure, which reduces weight while maintaining excellent pressure resistance. The protective mechanism 7 is made of wear-resistant rubber material, and the spiral groove 703 design on the surface not only enhances flexibility and can adapt to various complex working conditions, but also effectively reduces the phenomenon of easy damage under frequent bending and movement conditions.

[0028] The inner side of the reinforcing layer 502 has a cavity 6, and the outer wall of the coating 503 is connected to a protective mechanism 7. The protective mechanism 7 includes a sheath layer 701, the inner wall of the sheath layer 701 is attached to the outer wall of the coating 503, the inner wall of the sheath layer 701 is fixedly connected to the cord 702, the outer wall of the sheath layer 701 has a spiral groove 703, and the surface of the sheath layer 701 has an outer nameplate 8.

[0029] Working principle:

[0030] The smooth, mirror-like plastic sheath 4 on the outer wall of the insulation layer 2 makes it easier to pull out and insert the insulation layer 2 and the conductive layer 1 from the inside. The shielding layer 501 uses professional tin-plated copper mesh material. The tin plating process gives it strong anti-oxidation ability. The fine woven structure of the copper mesh is like a tight protective cover, which can effectively suppress external electromagnetic interference and ensure that power can be transmitted stably and smoothly inside, greatly improving the stability and reliability of transmission quality.

[0031] The reinforcing layer 502 in the reinforcing mechanism 5 adopts an aramid fiber braided structure. The aramid fiber itself has ultra-high strength and modulus, providing support for the entire power tube. The nanotube coating 503, which is closely bonded to it, has a unique microstructure and physical properties. It can quickly disperse stress when subjected to external impact. Furthermore, the carbon nanotube coating can effectively shield low frequencies and absorb high frequencies, significantly improving the tensile strength and shielding strength of the power tube and effectively extending the service life of the power tube.

[0032] The carefully designed cavity 6 inside the reinforcing layer 502 significantly reduces the overall weight, making the installation and transportation of the power pipe more convenient and reducing the difficulty and cost of operation. At the same time, the structure of the cavity optimizes the distribution of force, so that when the pipe is subjected to pressure, the pressure can be evenly transmitted and dispersed, avoiding excessive local pressure that could lead to deformation or damage.

[0033] The sheath layer 701 in the protective mechanism 7 is made of highly elastic rubber material, which has excellent wear resistance, flexibility and weather resistance. The cords 702 embedded inside it form a strong mesh support structure. When the tube is subjected to external force, the cords 702 can quickly disperse the external force to the entire sheath layer 701, avoiding localized stress concentration that could lead to damage. The spiral grooves 703 on the surface of the sheath layer 701 not only enhance its overall aesthetics, but more importantly, they work in synergy with the cords 702. When the tube is bent, the spiral grooves can act as guides, allowing the stress to be evenly distributed during bending, preventing excessive localized deformation of the tube, and ensuring that the tube maintains good flexibility and stability in various complex environments.

[0034] The outer nameplate 8 employs advanced laser etching technology. This process ensures that the markings remain clear and intact even after prolonged exposure to harsh environments such as sunlight, rain, and wind, without becoming blurred or fading. In practical use, maintenance personnel can quickly and accurately identify the pipe's parameters and specifications, greatly facilitating rapid repair and replacement of power pipes, effectively shortening maintenance time and improving work efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
