Further, the left sealed air cavity 3111 is further slowly compressed, so that the compressed air is released and passes through the ventilation cavity 3114 and the injection box 3202, and then enters the dry powder cavity 3115 to drive the dry powder downward, and the air pressure of the compressed air is slowly released, so that the impeller 3308 is driven to rotate and cannot move downward; meanwhile, the connecting plate 3402 and the spraying box 3202 are driven to rotate, so that meshing transmission of a second bevel gear 3502 and the first bevel gear 3401 can be formed, the second bevel gear 3502 rotates around the first bevel gear 3401, meanwhile, the second bevel gear 3502 can also rotate, and then the spraying box 3202 is driven to move while rotating, and annular, uniform, slow and sustainable spraying fire extinguishing on fire is completed.
The working process is as follows:
the fire extinguishing mechanism 3 is arranged at the upper end of an engine compartment of the automobile, and the pressure sensor 2 is arranged at the front end of the head of the automobile. When the car bumps, pressure sensor 2 detects pressure signal and then transmits for mechanism 3 of putting out a fire, and the explosion chamber 3110 intussuseption of mechanism 3 of putting out a fire is filled with combustible gas, and is equipped with automatic ignition ware in, after 2 perception car collision signals of pressure sensor, triggers automatic ignition ware.
After explosion occurs in the explosion cavity 3110, high-pressure gas generated by the explosion can be divided into two parts, and one part of the high-pressure gas can directly enter the dry powder cavity 3115 from the explosion cavity 3110 through the through hole 3116 and the one-way valve, so that the dry powder extinguishing agent stored in the dry powder cavity 3115 can be instantly sprayed. Specifically, the explosion air pressure entering the dry powder cavity 3115 can instantly drive the impeller 3308 and the sleeve 3303 to integrally move downward, so that the transmission rod 3404 is inserted into the fixing hole 3406 of the first bevel gear 3401 in a downward moving manner to be matched and fastened. At this time, a form in which the fixed shaft 3302 and the transmission rod 3404 are locked two shafts is formed, and the injection tank 3201 and the sleeve 3303 cannot rotate. The transmission rod 3404 moves downwards to drive the transmission plate 3405 to move downwards, so as to drive the bottom plate 3307 to move downwards, so that the bottom plate 3307 and the third shell 3306 are staggered to form a large-area nozzle, and finally large-area instant injection is completed. With the release of the pressure, the second elastic member 3314 will drive the bottom plate 3307 to move upward to achieve a quick reset; not only the prevention effect of the automobile collision fire is realized, but also the large-area rapid injection is realized to rapidly extinguish the fire.
The dry powder extinguishing agent is sprayed in the dry powder cavity 3115 instantly at high pressure, and the pressure is released; another portion of the high pressure gas generated by the explosion acts on the cushioning components within the upper chamber 3102. Specifically, the first elastic member 3108 and the hydraulic damper 3104 in the upper chamber 3102 can perform "energy storage" on energy generated by partial air pressure acting on the upper chamber 3102, that is, the third push plate 3109 is subjected to a large pressure and can reach the highest speed instantly when moving leftwards and rightwards in a unidirectional manner under the action of the ratchet 3117, but the energy storage is temporarily realized because the damping effect of the first elastic member 3108 and the hydraulic damper 3104 is slowly compressed, and then the energy is transferred to the sealed air chamber 3111. So that the left sealed air cavity 3111 is further slowly compressed, causing the compressed air to be released and to pass through the vent tube 3118 and the one-way valve into the dry powder cavity 3115, which in turn drives the dry powder downward through the nozzle at the bottom end of the spray box 3202 for spraying.
At this time, the air pressure of the compressed air is slowly released, so that the impeller 3308 and the sleeve 3303 are driven to rotate relative to the fixed shaft 3302, and at this time, the pressure is not enough to push the impeller 3308 to move downward due to the small pressure. At the same time, the sleeve 3303 drives the connecting plate 3402 and the ejection cartridge 3202 to rotate, and thus, the second bevel gear 3502 and the first bevel gear 3401 are in meshing transmission, that is, the second bevel gear 3502 rotates around the first bevel gear 3401, and at the same time, the second bevel gear 3502 also rotates. Further, the rotating shaft 3501 rotates to drive the spraying box 3202 to move, at the moment, the movement track of the nozzle at the bottom end of the spraying box 3202 is spiral, the radius of the nozzle is gradually increased, and the track of the sprayed dry powder is consistent with the track of the sprayed dry powder, so that the annular, uniform, slow and sustainable spraying fire extinguishment is completed; the practicability and the efficiency of the device are further improved; the dual purposes of the fire extinguishing agent after being sprayed suddenly and sprayed continuously are achieved, and the effect of preventing reignition at the ignition point is achieved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
