Description

Technical Field

[0001] This utility model relates to a combined thermal aerosol automatic fire extinguishing device, belonging to the technical field of fire extinguishing devices. Background Technology

[0002] Thermal aerosol fire extinguishing devices are a new type of fire extinguishing equipment. The fire extinguishing aerosol produced after activation is non-toxic, does not deplete the atmospheric ozone layer, and has high fire extinguishing efficiency. The product is easy to install and maintain, and is an ideal alternative to halon fire extinguishing equipment in certain specific locations.

[0003] While existing automatic thermal aerosol fire extinguishing systems are capable of routine firefighting operations, they become unusable after use due to the depletion of internal reactants, requiring replacement. Furthermore, the intact casing is recycled, resulting in resource waste and a low resource reuse rate. Additionally, the system generates a mixture of solid particles and gas during spraying; if these particles are not completely expelled, they can clog the nozzles. Subsequent reuse requires separate cleaning by personnel, causing inconvenience and further compromising the ease of use of automatic thermal aerosol fire extinguishing systems.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] This utility model provides a combined thermal aerosol automatic fire extinguishing device.

[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes an outer shell 1, which is a high-temperature resistant and flame-retardant shell 1. The outer shell 1 is made of PA6+30%GF injection molding and has a temperature resistance of 200 degrees Celsius. The inner part of the outer shell 1 has a placement groove 2, which is used to place the aerosol extinguishing agent body 4. There are two through holes 3 on both sides of the placement groove 2. The inner wall of the placement groove 2 is provided with the aerosol extinguishing agent body 4. The aerosol extinguishing agent body 4 contains aerosol extinguishing agent and coolant and can be used with a heat-sensitive wire 6 for hot start. There are two nozzles 5 on both sides of the aerosol extinguishing agent body 4. The heat-sensitive wires 6 are provided on both sides of the lower end of the aerosol extinguishing agent body 4. The middle part of the outer shell 1 has a sliding groove 7. The inner wall of the sliding groove 7 is provided with a connecting structure. The connecting structure includes a counterweight 8. A connecting rod 9 is fixed in the middle of the counterweight 8. The other end of the connecting rod 9 is rotatably connected to a connecting frame 10. The other end of the connecting frame 10 is rotatably connected to a closing plate 11.

[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the outer surface of the sealing plate 11 is slidably connected to the inner wall of the outer shell 1, the upper surface of the sealing plate 11 is in contact with the lower surface of the aerosol extinguishing agent body 4, the outer surface of the aerosol extinguishing agent body 4 is in contact with the inner wall of the placement groove 2, and several nozzles 5 correspond one-to-one with several through holes 3. The cross-section of the sealing plate 11 is U-shaped. The outer surface of the counterweight 8 is slidably connected to the inner wall of the slide groove 7. The upper end of the connecting rod 9 is fixed to the middle of the counterweight 8. The outer surface of the connecting rod 9 is slidably connected to the inner wall of the outer shell 1. The lower end of the connecting frame 10 is rotatably connected to the outer surface of the connecting rod 9, and the upper end of the connecting frame 10 is rotatably connected to one side of the sealing plate 11.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that mounting brackets 15 are fixed on both the upper and lower sides of the outer casing 1, and pre-drilled holes 16 are provided in the middle of both mounting brackets 15.

[0030] In use, this invention involves manually pulling the counterweight 8 upwards. The counterweight 8, stabilized by the sliding groove 7, moves the centrally fixed connecting rod 9 upwards. The upward-moving connecting rod 9, via the lower rotating connecting frame 10, moves the sealing plate 11 within the inner wall of the outer shell 1. When the sealing plate 11 moves away from below the aerosol extinguishing agent body 4, the aerosol extinguishing agent body 4 is unobstructed and can be easily disassembled. When the sealing plate 11 moves below the aerosol extinguishing agent body 4, the aerosol extinguishing agent body 4 is blocked by the sealing plate 11, thus encapsulating it within the placement groove 2. This achieves the effect of assembly and replacement. After use, only the reactants need to be replaced, allowing the outer shell 1 to be reused, thereby improving the resource utilization rate of the thermal aerosol automatic fire extinguishing device.

[0031] Example 2

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Embodiment 1, a convenient cleaning function has been added.

[0033] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that through slots 12 are provided on both sides of the outer shell 1, and fixed brackets 13 are fixed on both sides of the connecting rod 9. Brush holders 14 are fixed at both ends of the two fixed brackets 13. The outer surfaces of the two fixed brackets 13 are slidably connected to the inner walls of the two through slots 12. One end of each brush holder 14 is fixed to one end of each fixed bracket 13, and the bristles of each brush holder 14 are attached to the outer surface of the outer shell 1.

[0034] In use, this utility model involves manually pulling the counterweight 8 upwards. The counterweight 8, stabilized by the sliding groove 7, moves the centrally fixed connecting rod 9 upwards. The upward-moving connecting rod 9 then causes the two fixed brackets 13 on both sides to slide within the two through grooves 12. These sliding brackets 13 then move the brush holder 14 fixed to them. The moving brush holder 14 cleans the dust and impurities clogging the through holes 3, achieving convenient cleaning without requiring separate cleaning by personnel, thus improving the ease of use of the automatic thermal aerosol fire extinguishing device.
