DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] A quick-acting fire extinguisher, such as Figures 1-6As shown, it includes a mobile vehicle group, a fire extinguisher bottle 2, a valve 21, a delivery pipe 22, a movable nozzle 23, a fixing frame 31, a movable lock group, a transfer pipe 4, an extended nozzle 51, a side nozzle 52, a third compression spring 53 and a fusible link 54; the fire extinguisher bottle 2 is placed on the mobile vehicle group; the outlet end of the fire extinguisher bottle 2 is installed with a valve 21; the valve 21 is connected to the delivery pipe 22; the outlet end of the delivery pipe 22 is connected to the movable nozzle 23; the mobile vehicle group is connected to the fixing frame 31; the transfer pipe 4 is fixed to the fixing frame 31; the outlet end of the movable nozzle 23 is plugged into the transfer pipe 4; the outlet of the transfer pipe 4 A fixed nozzle structure 401 is provided at the end, and the fixed nozzle structure 401 is set as a flat mouth structure, which improves the lateral spray range of the fixed nozzle structure 401 on the fire powder; the outlet end of the adapter tube 4 is slidably connected to an extended nozzle 51; two symmetrical lateral nozzles 52 are connected to the extended nozzle 51; a third compression spring 53 is fixedly connected between the extended nozzle 51 and the adapter tube 4; two fusible wires 54 are fixedly connected between the extended nozzle 51 and the adapter tube 4, and the fusible wire 54 uses a cotton rope that can be quickly burned when exposed to open flames, and the third compression spring 53 is initially in a compressed state.

[0027] like Figure 1 As shown, the mobile vehicle group includes a mobile chassis 11, a push rod 12 and a lifting frame 13; the push rod 12 is connected to the mobile chassis 11; the lifting frame 13 is slidably connected to the push rod 12, and a damping strip is provided in the push rod 12 that is close to the lifting frame 13; the lifting frame 13 is connected to the fixed frame 31; the fire extinguisher bottle 2 is placed on the clamp component of the mobile chassis 11.

[0028] like Figure 5 As shown, two pressure rods 24 that are symmetrical to each other in the upper and lower directions are passed through and slidably connected to the movable sprinkler 23; a movable valve 25 is fixedly connected to the opposite sides of the two pressure rods 24, and the movable valve 25 is located in the movable sprinkler 23; a first compression spring 26 is fixedly connected between the two pressure rods 24 and the movable sprinkler 23; two clamping rods 41 are fixedly connected to the upper and lower sides of the transfer tube 4; the two clamping rods 41 on the upper side of the transfer tube 4 are jointly clamped on the pressure rod 24 on the upper side; the two clamping rods 41 on the lower side of the transfer tube 4 are jointly clamped on the pressure rod 24 on the lower side; the clamping rod 41 fixes the movable sprinkler 23 by clamping the pressure rod 24, so as to prevent the movable sprinkler 23 from loosening from the transfer tube 4 due to excessive recoil generated by spraying fire powder in the direction of the transfer tube 4.

[0029] When the user uses a quick-start fire extinguisher of the present invention, he first pulls the push rod 12 to control the mobile vehicle group to move the fire extinguisher bottle 2 to the area where the fire occurs, and makes the extended nozzle 51 and the side nozzle 52 face the burning site. Then, he turns the valve 21 to the open state, and the pressurized fire-fighting powder in the fire-extinguisher bottle 2 is transported to the extended nozzle 51 and the side nozzle 52 through the delivery pipe 22, the movable nozzle 23, and the adapter pipe 4 respectively. The fire-fighting powder is then sprayed outward from the extended nozzle 51 and the side nozzle 52 to the burning site at a long distance, so as to realize the quick start of the extended nozzle 51 and the side nozzle. The nozzle 52 automatically extinguishes the fire over a large area at a long distance in the area where the fire occurs, without the user having to approach the dangerous area where the fire occurs. The user can also drive the lifting frame 13 to move up and down along the push rod 12 according to the height and range of the fire in the burning site, and let the lifting frame 13 drive the transfer tube 4, the extended nozzle 51 and the side nozzle 52 to adjust the height in the up and down directions. The lifting frame 13 that has completed the lifting adjustment can hover at the current position on the push rod 12 through the friction with the damping strip, thereby realizing the adjustment of the automatic spraying area and automatic spraying range of the fire-fighting powder, thereby improving the automatic fire-fighting treatment effect.

[0030] During the automatic fire extinguishing process, when the user observes that the fire at the burning site is gradually weakening and is about to be controlled, the user first squeezes the two pressure rods 24 with one hand at the same time to drive the first compression spring 26 to compress, so that the two pressure rods 24 drive the two movable valves 25 to move towards each other and tightly adhere to the inside of the movable nozzle 23. The movable nozzle 23 is blocked by the two movable valves 25 tightly attached to each other, so that the fire powder is temporarily shut off and no longer flows through the movable nozzle 23 toward the transfer pipe 4. After being squeezed, the pressure rod 24 will leave the clamping rod 41, and the user can then Use the other hand to pull the movable sprinkler head 23 out of the adapter tube 4, and then the user releases the pressure rod 24. At the same time, the compressed first compression spring 26 pushes the pressure rod 24 to reset the movable valve 25, allowing the fire-fighting powder to continue to flow through the movable sprinkler head 23 and spray out. The user can then control the movable sprinkler head 23 to manually spray the fire-fighting powder toward the burning site. At this time, the fire-fighting powder is sprayed through the movable sprinkler head 23 instead of the extended sprinkler head 51 and the lateral sprinkler head 52, so that the movable sprinkler head 23 can be quickly started for more accurate manual fire extinguishing treatment, thereby improving the fire-fighting efficiency.

[0031] During the automatic fire extinguishing process, when the user observes that the fire at the burning site is not under control and evolves into a phenomenon of continuously spreading and burning, the user further avoids in the direction away from the burning site. At this time, when the spreading open flame contacts the fusible link 54 between the extended nozzle 51 and the adapter tube 4, the fusible link 54 will be burned out immediately. At the same time, the third compression spring 53, which is initially in a compressed state, pushes the extended nozzle 51 to drive the lateral nozzle 52 to pop outward away from the adapter tube 4. At this time, the fire-fighting powder flowing through the adapter tube 4 will be directly sprayed outward through the fixed nozzle structure 401, realizing the rapid start of the fixed nozzle structure 4 on the adapter tube 4. 01 performs large-scale automatic fire extinguishing at close range, and the diffusion range of the fire-fighting powder sprayed from the fixed nozzle structure 401 on the transfer tube 4 is much smaller than the diffusion range of the fire-fighting powder sprayed from the extended nozzle 51 and the side nozzle 52 at the same time. Therefore, the concentration of the fire-fighting powder sprayed from the fixed nozzle structure 401 on the transfer tube 4 will also be much greater than the concentration of the fire-fighting powder sprayed from the extended nozzle 51 and the side nozzle 52 at the same time, thereby improving the suppression effect of the fire-fighting powder on the spreading fire, slowing down the speed at which the fire spreads toward the fire extinguisher bottle 2, and buying time for the user to escape and the subsequent arrival of professional firefighters.

[0032] Example 2

[0033] On the basis of Example 1, Figures 1-6 As shown, the fixed frame 31 of this embodiment is rotatably connected to the lifting frame 13; the lifting frame 13 is provided with two front and rear sets of movable lock groups for fixing the fixed frame 31; the movable lock groups are composed of wedge-shaped locking blocks 32 and second compression springs 33; a plurality of wedge-shaped locking groove structures 310 are formed on the fixed frame 31; a wedge-shaped locking block 32 aligned with the wedge-shaped locking groove structures 310 is slidably connected to the lifting frame 13; a second compression spring 33 is fixedly connected between the wedge-shaped locking block 32 and the lifting frame 13; the wedge-shaped locking block 32 is inserted into the adjacent wedge-shaped locking groove structures 310, and the second compression spring 33 is initially in a compressed state.

[0034] During the automatic fire extinguishing process, the user only needs to forcefully turn the fixing bracket 31 up and down to drive the fixing bracket 31 to push the wedge-shaped locking block 32 downward through the wedge-shaped locking groove structure 310. At the same time, the wedge-shaped locking block 32 drives the second compression spring 33 to compress downward, so that the fixing bracket 31 is no longer restricted by the wedge-shaped locking block 32 and can smoothly drive the transfer tube 4, the extended nozzle 51 and the side nozzle 52 to adjust the angle in the up and down directions, thereby realizing the control and automatic locking of the automatic fire extinguishing angle of the transfer tube 4, the extended nozzle 51 and the side nozzle 52.

[0035] Example 3

[0036] On the basis of Example 2, Figure 1-Figure 7As shown, the push rod 12 of this embodiment is rotatably connected to the mobile chassis 11 via a rotating shaft; a flap 14 is rotatably connected to the mobile chassis 11 via a rotating shaft; two insertion rods 15 are welded to the flap 14; the two insertion rods 15 are jointly inserted into the push rod 12, so that the mobile chassis 11 fixes the push rod 12 through the insertion rods 15; a pedal 16 is welded to the flap 14.

[0037] When extinguishing a fire in a parking lot, if a fire occurs on the vehicle chassis, the user only needs to step on the pedal 16 to turn the flap 14 downward, and let the flap 14 drive the insertion rod 15 downward to leave the push rod 12, completing the quick unlocking process of the push rod 12. Then, the user turns the push rod 12 and drives the fixing frame 31, the transfer tube 4, the extended nozzle 51 and the side nozzle 52 to turn downward by 90 degrees. At the same time, the user turns the fixing frame 31 to drive the transfer tube 4, the extended nozzle 51 and the side nozzle 52 to turn right by 90 degrees. Figure 8 As shown, the extended nozzle 51 and the side nozzle 52 are placed against the ground and aligned with the chassis of the vehicle on fire. Then, the user opens the valve 21 of the fire extinguisher bottle 2, and the extended nozzle 51 and the side nozzle 52 can spray fire powder in a large range toward the vehicle chassis, automatically completing the fire extinguishing process of the vehicle chassis. The user does not need to approach the vehicle on fire to extinguish the fire, thereby providing protection for the user's personal safety.
