Description

Technical Field

[0001] This utility model relates to the field of aerosol fire extinguishing technology, specifically to a thermal aerosol fire extinguishing device. Background Technology

[0002] Aerosol fire extinguishing devices contain a solid agent that is released as an aerosol through an oxidation-reduction reaction, such as the aerosol fire extinguishing device with application number CN202122461473.X. When a fire occurs, an ignition element ignites the aerosol, which burns within the inner cavity, producing a large amount of solid particles and extinguishing gas. This large amount of extinguishing gas is then released through multiple outlets to extinguish the fire. However, existing aerosol fire extinguishing devices have nozzles positioned vertically downwards, resulting in poor outward diffusion and a limited extinguishing range. Furthermore, aerosol fire extinguishing devices are typically installed using clamps, requiring replacement of the clamps when changing to different models, leading to limited applicability.

Detailed Implementation

[0020] Example 1: A preferred embodiment of this utility model provides a thermal aerosol fire extinguishing device, including a housing 110, a thermal start line 120, a guide fluid 160, a clamping assembly 170, and an installation assembly 180. The thermal start line 120 is connected to the top of the housing 110. The guide fluid 160 is constructed at the nozzle of the outer ring nozzle 150 at the bottom of the housing 110. The guide fluid 160 is a strip structure, and its installation end is fixed at the nozzle of the outer ring nozzle 150. Alternatively, it can be integrally formed with the housing 110. The guide fluid 160 is inclined in a direction away from the housing 110, thereby providing a guiding effect for the aerosol to be sprayed outward. The inner ring nozzle 140, which does not have the guide fluid 160 at its nozzle, continues to spray downward. The outer ring nozzle 150 and the inner ring nozzle 140 are used in combination to enable the fire extinguishing aerosol to be sprayed in multiple directions to extinguish the fire, thereby increasing the fire extinguishing range.

[0021] Example 2: A preferred embodiment of this utility model provides a thermal aerosol fire extinguishing device, which differs from the above embodiments only in that:

[0022] The clamping assembly 170 is mounted on the outer shell 110. The clamping assembly 170 is used to clamp and fix various models of the outer shell 110. The clamping assembly 170 includes a first arc-shaped mother plate 171, a second arc-shaped mother plate 172, an arc-shaped insert plate 173, a threaded rod 174, a nut 175, and a latch 176. The two ends of the arc-shaped insert plate 173 are slidably inserted into the first arc-shaped mother plate 171 and the second arc-shaped mother plate 172, respectively. One end of the threaded rod 174 is fixed to the outer wall of the arc-shaped insert plate 173. Several threaded rods 174 pass through the first arc-shaped mother plate 171 and the second arc-shaped mother plate 172, respectively. The nut 175... 5. The threaded sleeve is fitted onto the threaded rod 174. The corresponding two second arc-shaped mother plates 172 are fixed together by the buckle 176. The first arc-shaped mother plate 171 and the second arc-shaped mother plate 172 are snapped onto the outer shell 110. The outer shell 110 has a slot 130. The first arc-shaped mother plate 171 and the second arc-shaped mother plate 172 are snapped into the slot 130. Both the first arc-shaped mother plate 171 and the second arc-shaped mother plate 172 have a strip-shaped through groove 177. The threaded rod 174 passes through the strip-shaped through groove 177. The setting of the strip-shaped through groove 177 facilitates the adjustment of the distance between the first arc-shaped mother plate 171 and the second arc-shaped mother plate 172.

[0023] Example 3: A preferred embodiment of this utility model provides a thermal aerosol fire extinguishing device, which differs from the above embodiments only in that:
