Description

Technical Field

[0001] This utility model relates to the field of safety rope technology, and in particular to a flame-retardant safety rope. Background Technology

[0002] For space-constrained but functionally important equipment, such as meter boxes, distribution cabinets, switch boxes, frequency converter cabinets, control cabinets, server racks, and other electrical cabinets, these are primarily used for power distribution, equipment control, and automatic power cut-off in case of overload, short circuit, or leakage, providing safety protection. These electrical cabinets typically house numerous electronic components, terminals, cables, and other complex electrical equipment. The confined space and abundance of flammable materials create a high fire risk. Due to their compact structure, traditional fire suppression systems are often difficult to install and function effectively. Therefore, implementing targeted electrical fire prevention and suppression measures is crucial.

[0003] Therefore, there is an urgent need for a flame-retardant safety rope with embedded fire-extinguishing microcapsules that can be freely installed near the ignition point. When a fire occurs inside an electrical cabinet, it can precisely extinguish the fire by cooling and isolating oxygen, thus effectively preventing electrical fires. Utility Model Content

[0004] This addresses the problem that traditional fire suppression systems often struggle to be effectively installed and function properly in electrical cabinets.

[0005] This utility model provides a flame-retardant safety rope, including a load-bearing rope body, a protective layer, and a metal strip; the load-bearing rope body has a flat structure and is used to provide load-bearing tensile force; the protective layer is located on the left and right sides of the load-bearing rope body, and the protective layer is filled with fire extinguishing microcapsules, the inside of which contains fire extinguishing agent, and the protective layer is used for flame retardant fire extinguishing; the metal strip is located at the top and bottom of the load-bearing rope body and is used to conduct heat.

[0006] Preferably, the fire extinguishing microcapsule includes a wall material and a core material, with the core material encapsulated inside the wall material, and the core material is perfluorohexanone fire extinguishing agent.

[0007] Preferably, the wall material is selected from polyurea-formaldehyde resin, melamine resin, and polyvinyl alcohol.

[0008] Preferably, the load-bearing rope is made of one of polyester fiber, nylon or polypropylene.

[0009] Preferably, the metal strip is selected from one of galvanized steel strip, stainless steel strip, or aluminum alloy strip.

[0010] Preferably, the outer side of the load-bearing rope is wrapped with a heat insulation layer.

[0011] Preferably, the insulation layer is made of one of aramid fibers, polyimide fibers or polybenzimidazole fibers.

[0012] Preferably, at least one end of the flame-retardant safety rope is provided with an encapsulation sleeve, and the encapsulation sleeve is provided with a D-ring.

[0013] The beneficial effects of this utility model are reflected in: 1) By setting a load-bearing rope, the overall mechanical strength of the flame-retardant safety rope is ensured. The load-bearing rope is placed in the middle of the flame-retardant safety rope to reduce the possibility of it being burned through, so that it can have a certain binding performance in addition to its fire extinguishing and flame-retardant performance.

[0014] 2) By setting up a protective layer, the fire extinguishing microcapsules rupture and release the fire extinguishing agent when heated, thus extinguishing the fire.

[0015] 3) By setting up metal strips, local abnormal high temperatures can be quickly captured and the heat can be rapidly conducted to the entire length of the rope. This allows the heat to be quickly transferred to a sufficiently long range through the metal strips, even if the fire hazard is only a section of the safety rope, thereby triggering the fire extinguishing microcapsules in a larger area. This enables rapid response and coverage fire extinguishing, avoiding situations where the fire extinguishing agent cannot be activated due to the small size of the hot spot.

[0016] The entire fire extinguishing process is triggered by heat, allowing for automatic suppression in the early stages, making it suitable for unattended electrical cabinets. This solves the problem that traditional fire suppression systems often struggle to be effectively installed and function properly around electrical cabinets. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figures 1-2A flame-retardant safety rope includes a load-bearing rope body 1, a protective layer 3, and a metal strip 4. The load-bearing rope body 1 has a flat structure and is used to provide load-bearing tensile force. The protective layer 3 is located on the left and right sides of the load-bearing rope body 1. The protective layer 3 is filled with fire extinguishing microcapsules, and the fire extinguishing microcapsules contain fire extinguishing agents. The protective layer 3 is used for flame retardant fire extinguishing. The metal strip 4 is located at the top and bottom of the load-bearing rope body 1 and is used to conduct heat.

[0022] By setting up a load-bearing rope 1, the overall mechanical strength of the flame-retardant safety rope is ensured. Positioning the load-bearing rope 1 in the middle of the flame-retardant safety rope reduces the possibility of it burning through, giving it both fire-retardant and fire-extinguishing properties, as well as some binding performance. By setting up a protective layer 3, the fire-extinguishing microcapsules rupture and release the extinguishing agent when heated, thus extinguishing the fire. By setting up a metal strip 4, localized abnormal high temperatures can be quickly captured and the heat rapidly conducted along the entire length of the rope. This ensures that even if the fire hazard is only adjacent to a section of the safety rope, the heat can be quickly transferred to a sufficiently long area through the metal strip 4, triggering the fire-extinguishing microcapsules over a larger area, achieving rapid response and comprehensive fire suppression, avoiding situations where the fire extinguishing agent cannot be activated due to a small hotspot. The entire fire extinguishing process is entirely heat-triggered, allowing for automatic extinguishing in the nascent stage, making it suitable for unattended electrical cabinets. This solves the problem that traditional fire extinguishing systems are often difficult to install effectively and function properly for electrical cabinets.

[0023] In some embodiments, the fire extinguishing microcapsule includes a wall material and a core material, with the core material encapsulated inside the wall material, and the core material being perfluorohexanone fire extinguishing agent.

[0024] Perfluorohexanone liquid contains no freely moving charged ions and does not react with most materials upon contact. It has good insulation properties, making it suitable for extinguishing fires involving electrical equipment. It will not cause secondary electric shock accidents, nor will it damage electronic components and wiring, thus avoiding secondary damage. However, perfluorohexanone is susceptible to environmental conditions such as light, temperature, and humidity. Encasing it in wall materials can effectively prevent the extinguishing agent from evaporating or degrading due to these external factors, thereby ensuring its long-term effectiveness.

[0025] Preferably, the wall material is selected from polyurea-formaldehyde resin, melamine resin, and polyvinyl alcohol.

[0026] Polyurea-formaldehyde resin, melamine resin, or polyvinyl alcohol all possess high mechanical strength, excellent sealing properties, designable thermal response, good chemical stability, and absolute insulation. These properties ensure that the extinguishing agent remains effective for a long period and is precisely activated at the critical point of a fire, thus solving the core problem of the difficulty in extinguishing fires involving electrical cabinets. Furthermore, as an explanation rather than a limitation, the thickness and porosity of the microcapsule wall material can be adjusted by changing the polymer ratio or adding specific additives, thereby controlling the release rate of the extinguishing agent.

[0027] In some embodiments, the load-bearing rope 1 is made of one of polyester fiber, nylon or polypropylene.

[0028] Polyester fiber is known for its high strength, abrasion resistance, and good resistance to ultraviolet rays and chemical corrosion, making it suitable for long-term outdoor use; nylon has excellent elasticity and shock absorption capacity, and it also has excellent abrasion resistance and fatigue resistance; polypropylene is lightweight and soft.

[0029] Choosing polyester fiber, nylon, or polypropylene as the load-bearing rope body 1 ensures the physical reliability of the safety rope, enabling it to adapt to the complex environment of the electrical cabinet and perform bending and binding functions. At the same time, its thermal and chemical properties work in synergy with the fire extinguishing function of the upper layer, neither prematurely damaging the structure nor interfering with fire extinguishing.

[0030] In some embodiments, the metal strip 4 is selected from galvanized steel strip, stainless steel strip, or aluminum alloy strip.

[0031] Galvanized steel strips, stainless steel strips, or aluminum alloy strips can quickly capture the heat from localized hot spots and rapidly conduct it longitudinally along the rope, thereby triggering a synchronous response of fire extinguishing microcapsules over a larger area. This solves the problem that insufficient fire extinguishing agent may not be effectively activated due to the small size of the fire source, and realizes the precise fire extinguishing function from passively waiting to actively searching for heat sources.

[0032] In some embodiments, the outer side of the load-bearing rope 1 is wrapped with a heat insulation layer 2.

[0033] Reference Figure 2 By setting up the heat insulation layer 2, the internal load-bearing rope 1 is protected from high temperature damage, ensuring that it maintains its structural strength in a fire.

[0034] Preferably, the heat insulation layer 2 is made of one of aramid fibers, polyimide fibers or polybenzimidazole fibers.

[0035] By utilizing the extreme high-temperature resistance, low thermal conductivity, and non-flammability of aramid, polyimide, or polybenzimidazole fibers, a robust thermal barrier is formed to ensure that the high temperature of an external fire will not prematurely burn the internal load-bearing rope 1, causing it to break.

[0036] Reference Figure 1 In some embodiments, at least one end of the flame-retardant safety rope is provided with an encapsulation sleeve 5, and the encapsulation sleeve 5 is provided with a D-ring 51.

[0037] By setting up the encapsulation sleeve 5 and D-ring 51, a high-strength, standardized, and quick connection point is provided for the flame-retardant safety rope, allowing users to directly connect it to the cabinet anchor point or electrical equipment without tying knots, thus improving installation efficiency and reliability.
