Description

Technical Field

[0001] This utility model relates to the field of flame-retardant fabric technology, specifically to an emergency cooling device for flame-retardant fabrics. Background Technology

[0002] Flame-retardant fabrics are fire-resistant clothing materials. Their main function is to prevent or slow down combustion, protecting people's lives and property. Specifically, flame-retardant fabrics do not ignite immediately upon contact with a fire source, or they burn very slowly and can self-extinguish within a certain time. This characteristic makes flame-retardant fabrics widely used in many fields. Firefighting suits are one of the important applications of flame-retardant fabrics. Firefighting suits need to have good flame-retardant, heat-insulating, and waterproof properties to protect the safety of firefighters at fire scenes.

[0003] While existing flame-retardant fabrics can delay combustion, they still accumulate heat under sustained high temperatures, causing a sharp rise in internal temperature. Furthermore, prolonged exposure of flame-retardant fabrics to high temperatures can lead to the breakage of aramid fiber molecular chains and damage to the fabric, which can also affect user safety. To address these issues, we propose an emergency cooling device for flame-retardant fabrics. Utility Model Content

[0011] This utility model provides an emergency cooling device for flame-retardant fabrics, which has the following beneficial effects:

[0012] (1) This utility model monitors the temperature of the part of the flame-retardant fabric that is in close contact with the human body, i.e. the interlayer, in real time through the set temperature sensor. After the temperature reaches the set value, the signal is transmitted to the control unit through the wireless communication module.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, an emergency cooling device for flame-retardant fabric includes a flame-retardant fabric 1 and an external box 2. The external box 2 contains an installation box 3, which in turn contains a fixing base 21. A high-pressure gas tank 5 and a liquid storage tank 6 are mounted on the fixing base 21. The installation box 3 contains a pressure regulating valve 7 corresponding to the high-pressure gas tank 5, a liquid proportioning valve 8 corresponding to the liquid storage tank 6, a dual-fluid nozzle 9, a gas-liquid mixing box 10, and an atomizing nozzle 11. The pressure regulating valve 7 is connected to the high-pressure gas tank 5 and the dual-fluid nozzle 9 via pipelines. The liquid proportioning valve 8 is connected to the liquid storage tank 6 and the dual-fluid nozzle 9 via pipelines. The gas-liquid mixing box 10 is connected to the dual-fluid nozzle 9 and the atomizing nozzle 11 via pipelines. A sandwich layer 4 is formed within the flame-retardant fabric 1, and the atomizing nozzle 11 is located within this sandwich layer 4. A temperature sensor 12 is located within the sandwich layer 4. The mounting box 3 is equipped with a control unit 13 and a wireless communication module 14. The temperature sensor 12 monitors the temperature of the part of the flame-retardant fabric that is in close contact with the human body, namely the interlayer 4, in real time. After the temperature reaches the set value, the signal is transmitted to the control unit 13 through the wireless communication module 14. The control unit 13 controls the air pressure regulating valve 7 and the liquid proportioning valve 8 to open simultaneously through the wireless communication module 14. The high-pressure gas and liquid in the high-pressure gas tank 5 and the liquid storage tank 6 are delivered to the dual-fluid nozzle 9 and the gas-liquid mixing box 10. The high-pressure gas shears the liquid in the Venturi mixing chamber of the gas-liquid mixing box 10 to form a micro-mist, which is then sprayed through the atomizing nozzle 11. The high-pressure gas tank 5 is filled with carbon dioxide gas, and the liquid storage tank 6 is filled with water mixed with flame retardant. The dual cooling is achieved by the sublimation heat absorption of carbon dioxide and the evaporation heat absorption of water. The flame retardant in the water can enhance the fire resistance of the residual layer after cooling, thus achieving emergency cooling of the flame-retardant fabric.

[0022] like Figure 4 and Figure 5As shown, two sets of symmetrically distributed rotating rings 22 are rotatably installed inside the fixed base 21. Each set of rotating rings 22 is fitted with a toothed ring 24. Multiple sets of annularly distributed clamping plates 23 are provided inside the fixed base 21. These clamping plates 23 are rotatably connected to the fixed base 21 via mounting shafts 25. Gears 26 are fitted onto each of the mounting shafts 25, and these gears 26 mesh with the toothed rings 24. The clamping plates 23 are respectively attached to the outer wall of the corresponding high-pressure gas tank 5 or liquid storage tank 6. Two sets of cross-distributed first supports 15 are provided between the mounting box 3 and the external box 2. First sliders 16 are rotatably installed at both ends of the two sets of first supports 15. The mounting box 3 and the external box 2... Each box 2 has a first sliding rod 17 fixedly installed inside. A damping rod 19 is fixedly installed between the first slider 16 and the corresponding mounting box 3 or external box 2. A third spring 20 is sleeved on the damping rod 19. The first slider 16 is slidably sleeved with the corresponding first sliding rod 17. A first spring 18 is sleeved on the first sliding rod 17. The two ends of the first spring 18 are fixedly connected to the first slider 16 and the mounting box 3 or external box 2, respectively. Two sets of symmetrically distributed second supports 27 are provided between the fixed base 21 and the mounting box 3. The second supports 27 are rotatably connected to the fixed base 21 through a rotating shaft. The end of the second support 27 away from the fixed base 21 is rotatably mounted with a third spring 20. The second slider 28 has a second sliding rod 29 fixedly installed inside the mounting box 3. An air spring 31 is fixedly installed between the second slider 28 and the mounting box 3. The second slider 28 and the second sliding rod 29 are slidably connected. A second spring 30 is sleeved on the second sliding rod 29. The two ends of the second spring 30 are fixedly connected to the second slider 28 and the mounting box 3, respectively. The installation and fixation of the high-pressure gas tank 5 and the liquid storage tank 6 are achieved through the fixed seat 21 and multiple sets of clamping plates 23 in the mounting box 3. The first bracket 15, the first slider 16, the damping rod 19 and the third spring 20 cooperate with the second bracket 27 and the second slider 28. The air spring 31 and other components provide shock absorption and anti-collision protection for the mounting box 3 and the components installed in the mounting box 3, so as to avoid damage to the internal structure of the cooling device due to the user running or shaking during the use of the flame-retardant fabric. When the outer box 2 shakes or is hit, the third spring 20, damping rod 19 and air spring 31 deform to absorb energy and release the energy generated by the vibration, so as to avoid adverse effects on the internal components as much as possible. At the same time, both the outer box 2 and the mounting box 3 in the cooling device are made of high temperature resistant heat insulation materials to ensure the normal operation of the components in the mounting box 3 as much as possible and maintain the stability of the emergency cooling device.

[0023] This utility model provides an emergency cooling device for flame-retardant fabrics. The specific working principle is as follows: A temperature sensor 12 monitors the temperature in real time in the part of the flame-retardant fabric closest to the human body, i.e., the interlayer 4. Once the temperature reaches a set value, the signal is transmitted to the control unit 13 via a wireless communication module 14. The control unit 13, through the wireless communication module 14, controls the simultaneous opening of the pressure regulating valve 7 and the liquid proportioning valve 8, delivering the high-pressure gas and liquid from the high-pressure gas tank 5 and the liquid storage tank 6 to the dual-fluid nozzle 9 and the gas-liquid mixing chamber 10. The high-pressure gas shears the liquid in the Venturi mixing chamber of the gas-liquid mixing chamber 10 to form a micro-mist, which is then sprayed through the atomizing nozzle 11. The high-pressure gas tank 5 is filled with carbon dioxide gas, and the liquid storage tank 6 is filled with water mixed with a flame retardant. The device utilizes the dual cooling effect of carbon dioxide sublimation and water evaporation absorption. The flame retardant in the water enhances the fire resistance of the residual layer after cooling, thus achieving effective cooling of the flame-retardant fabric. Emergency cooling is achieved by using the fixed base 21 and multiple sets of clamping plates 23 in the installation box 3 to install and fix the high-pressure gas tank 5 and the liquid storage tank 6. The first bracket 15, the first slider 16, the damping rod 19 and the third spring 20, together with the second bracket 27, the second slider 28 and the air spring 31, provide shock absorption and anti-collision protection for the installation box 3 and the components installed in the installation box 3. This prevents damage to the internal structure of the cooling device due to running or shaking by the user during use with the flame-retardant fabric. When the outer box 2 shakes or is hit, the third spring 20, the damping rod 19 and the air spring 31 deform to absorb energy and release the energy generated by the vibration, minimizing adverse effects on the internal components. At the same time, both the outer box 2 and the installation box 3 in this cooling device are made of high-temperature resistant heat-insulating materials to ensure the normal operation of the components in the installation box 3 and maintain the stability of the emergency cooling device.
