Abstract
Description
Technical Field
[0001] This utility model relates to the field of flame-retardant cable protection pipe technology, specifically a flame-retardant cable protection pipe. Background Technology
[0002] Cable protection conduits, especially those installed in densely packed or high-temperature environments, must possess flame-retardant properties to prevent the spread of fire. Existing flame-retardant protective conduits mostly achieve this by adding halogen-based or phosphorus-based flame retardants. While these can delay combustion, they may release toxic fumes (such as halogen gases), endangering personal safety and the environment. Halogen-free flame-retardant technologies (such as aluminum hydroxide and nitrogen-based flame retardants) are more environmentally friendly, but suffer from problems such as high dosage requirements, decreased mechanical properties, and high costs. Some metal protective conduits, while possessing excellent flame retardancy, have poor insulation and are prone to thermal conductivity, making them unsuitable for all scenarios.
[0003] Furthermore, existing cable protection pipes only have passive flame-retardant function and lack active flame-retardant function, leaving room for improvement. Utility Model Content
[0004] The purpose of this utility model is to provide a flame-retardant cable protection pipe to solve the problems mentioned in the background art and overcome its technical defects.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a flame-retardant cable protection tube, including an outer layer, a protective tube interlayer, and an inner layer, wherein the outer layer, the protective tube interlayer, and the inner layer are arranged sequentially from the outside to the inside; a heat-conducting element is provided between the outer layer and the protective tube interlayer, and between the protective tube interlayer and the inner layer; a circumferentially distributed heat-conducting material is provided inside the protective tube interlayer; and a ring-shaped array of heat-conducting tracks is movably connected inside the inner layer of the protective tube.
[0006] As a further embodiment of this utility model: a flame-retardant cable protection pipe, wherein the heat-conducting track includes a heat dissipation guide rail, and a mating groove is provided inside the inner layer of the protection pipe, and the heat dissipation guide rail is adapted to the mating groove.
[0007] As a further embodiment of this utility model: a flame-retardant cable protection pipe, the heat-conducting component includes an outer heat-dissipating armor and an inner heat-dissipating armor, the outer heat-dissipating armor is disposed in the interlayer between the outer layer of the protection pipe and the interlayer of the protection pipe, and the inner heat-dissipating armor is disposed in the interlayer between the interlayer of the protection pipe and the inner layer of the protection pipe.
[0008] As a further embodiment of this utility model: a flame-retardant cable protection pipe, the heat-conducting material includes a corrugated ring, a receiving cavity, a cooling column and a hexagon, the corrugated ring is fixedly installed inside the hexagon, the receiving cavity is opened between the corrugated ring and the hexagon, and the cooling column is disposed inside the receiving cavity.
[0009] As a further embodiment of this utility model: a flame-retardant cable protection pipe, wherein the hexagonal structure is honeycomb-shaped and distributed in a ring array on the inner and outer walls of the protective pipe interlayer.
[0010] As a further embodiment of this utility model: a flame-retardant cable protection pipe, wherein the heat dissipation guide rail and the mating groove are configured with a tenon and mortise structure to prevent detachment.
[0011] As a further embodiment of this utility model: a flame-retardant cable protection pipe, wherein the corrugated ring, cooling column and hexagon are all made of gel.
[0012] As a further embodiment of this utility model: a flame-retardant cable protection pipe, wherein both the outer heat dissipation armor and the inner heat dissipation armor are made of copper alloy with good thermal conductivity.
[0013] Compared with the prior art, the beneficial effects of this utility model include:
[0014] Because the outer layer, the interlayer, and the inner layer of the protective tube are arranged sequentially from the outside to the inside, and heat-conducting components are provided between the outer layer and the interlayer, and between the interlayer and the inner layer, the inner layer of the protective tube has circumferentially distributed heat-conducting material inside, and the inner layer of the protective tube has a movably connected annularly arrayed heat-conducting track inside. Specifically, the heat-conducting track includes a heat dissipation guide rail. The inner layer of the protective tube has a mating groove inside, and the heat dissipation guide rail is adapted to the mating groove. Therefore, when the cable is assembled with the cable protection tube, the heat generated by its operation can be evenly discharged to the cable protection tube, avoiding the risk of local overheating of the cable protection tube leading to high-temperature melting or even fire.
[0015] Since the heat-conducting component includes an outer heat-dissipating armor and an inner heat-dissipating armor, with the outer heat-dissipating armor disposed in the interlayer between the outer layer and the inner layer of the protective tube, and the inner heat-dissipating armor disposed in the interlayer between the inner layer and the outer layer of the protective tube, the cable protective tube can quickly dissipate heat into the metal armor with a small specific heat capacity after being heated, thus achieving rapid heat dissipation of the cable.
[0016] Since the thermally conductive material includes a corrugated ring, a receiving cavity, a cooling column, and a hexagon, the corrugated ring is fixedly installed inside the hexagon, the receiving cavity is opened between the corrugated ring and the hexagon, and the cooling column is disposed inside the receiving cavity. Since both the corrugated ring and the cooling column are made of gel, the gel will burst open when heated during a high-temperature fire, shielding the fire and promoting the extinguishing of the fire.
