Technical Field
[0001] This utility model relates to the field of fire protection equipment technology, specifically a smoke extinguishing and fire suppression device for fire protection. Background Technology
[0002] Firefighting is the elimination of hidden dangers and prevention of disasters. In its narrower sense, it initially referred to fire. It primarily includes personnel rescue at fire scenes, the salvage of important facilities, equipment, and cultural relics, the protection and rescue of important property, and extinguishing fires. The aim is to reduce the extent of damage caused by fires and minimize casualties and property losses.
[0003] Firefighting requires smoke suppression and extinguishing devices, but existing devices have limitations. They often only adjust the extinguishing height but cannot expand the extinguishing range. Manual operation is required to achieve a larger extinguishing range, which wastes unnecessary manpower and time and makes them inconvenient for people to use. Utility Model Content
[0004] The purpose of this utility model is to provide a fire-fighting smoke suppression and extinguishing device, which has the advantage of being able to move the nozzle back and forth during spray extinguishing, thus giving the device a larger extinguishing range.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire-fighting smoke extinguishing device, including a trolley, wherein the surface of the trolley is provided with a fire extinguishing mechanism and a smoke extinguishing mechanism;
[0006] The fire extinguishing mechanism includes a water tank, a delivery pump connected to the surface of the water tank, a fixed frame and a cylinder fixed to the top of the trolley, one end of the cylinder passing through the fixed frame and fixed to a movable plate, a mounting shell fixed to the top of the movable plate, a motor housing fixed to the top of the mounting shell, a motor output shaft inside the motor housing passing through the mounting shell and fixed to a reciprocating lead screw, a slider threaded to the surface of the reciprocating lead screw, a rack fixed to the surface of the slider, a side plate fixed to the surface of the mounting shell, a rotating shaft rotatably connected to the surface of the side plate, a gear fixed to the surface of the rotating shaft, spray pipes fixed to both ends of the rotating shaft, a flexible hose connected to the surface of the delivery pump, and a mounting frame fixed above the surface of the mounting shell.
[0007] As a preferred embodiment of the fire-fighting smoke extinguishing device of this utility model, the smoke extinguishing mechanism includes a filter box, an exhaust fan is connected to the lower side of the inner wall of the filter box through a pipe, an exhaust pipe is connected to the top of the filter box, an exhaust shell is connected to the surface of the exhaust pipe, the exhaust shell is fixedly connected to the surface of the mounting bracket, and two filter plates are provided inside the filter box.
[0008] As a preferred embodiment of the fire-fighting smoke extinguishing device of this utility model, the inner wall of the exhaust shell is fixed with a grille, and a filter screen is provided on the upper part of the filter box.
[0009] As a preferred embodiment of the fire-fighting smoke extinguishing device of this utility model, the inner wall of the filter box is fixed with three U-shaped shells, the surface of the U-shaped shells is provided with placement grooves, the filter screen and filter plate are slidably connected to the placement grooves on the surface of the U-shaped shells, and the surface of the filter box is hinged with a door.
[0010] As a preferred embodiment of the fire-fighting smoke extinguishing device of this utility model, the upper filter plate is an activated carbon filter plate, and the lower filter plate is an HPEA filter plate.
[0011] As a preferred embodiment of the fire-fighting smoke extinguishing device of this utility model, both the exhaust pipe and the flexible hose are fitted with corrugated pipes.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, through the design of the fire extinguishing mechanism, enables the device to have a larger fire extinguishing range. During fire extinguishing, the height of the movable plate can be adjusted by starting the cylinder, thereby changing the height position of the sprinkler pipe to meet the needs of fire extinguishing at various heights. When it is necessary to expand the fire extinguishing range, the motor inside the motor box is started, causing the reciprocating screw to rotate. This causes the slider to be affected by the thread, driving the rack to move up and down. During this process, the rack drives the gear to rotate back and forth, causing the rotating shaft to drive the sprinkler pipe to rotate back and forth, thereby achieving a fan-shaped spraying effect. Through the rotation of the fan-shaped range, the sprinkler pipe can dynamically change the direction of water spraying, expanding the coverage area of the water flow. It is particularly suitable for irregular spaces or occasions requiring all-round fire extinguishing. This design can more effectively reach all corners of the fire scene, reduce fire extinguishing blind spots, and expand the fire extinguishing range.
[0014] 2. This utility model enables the device to perform smoke elimination by setting up a smoke elimination mechanism. When the exhaust fan is started, it can draw air into the filter box, so that the filter box can generate negative pressure, thereby allowing the exhaust shell to draw in the outside smoke and transport it into the filter box through the exhaust pipe. Then, it is filtered by two filter plates to finally achieve the smoke elimination effect. Attached Figure Description

[0022] Please see Figures 1-6 A fire-fighting smoke extinguishing device includes a trolley 1, on the surface of which a fire extinguishing mechanism 2 and a smoke extinguishing mechanism 3 are provided;
[0023] The fire extinguishing mechanism 2 enables the device to have a larger fire extinguishing range, and the smoke elimination mechanism 3 enables the device to perform smoke elimination.
[0024] Fire extinguishing mechanism 2 includes a water tank 201, with a delivery pump 202 connected to its surface. Both the water tank 201 and the delivery pump 202 are fixed to the top of a trolley 1. A mounting bracket 203 and a cylinder 204 are fixed to the top of the trolley 1. One end of the cylinder 204 passes through the mounting bracket 203 and is fixed to a movable plate 205. The movable plate 205 is slidably connected to the surface of the mounting bracket 203. A mounting shell 206 is fixed to the top of the movable plate 205. A motor housing 207 is fixed to the top of the mounting shell 206. Inside the motor housing 207, the motor output shaft passes through the mounting shell 206 and is fixed to a reciprocating screw 208. The bottom of the reciprocating screw 208 is rotatably connected to the inner wall of the mounting shell 206. The surface of the housing 206 is provided with a sliding groove. The reciprocating screw 208 is threadedly connected to a slider 209. The slider 209 is slidably connected to the surface of the sliding groove. A rack 210 is fixed to the surface of the slider 209. A side plate 211 is fixed to the surface of the housing 206. A rotating shaft 212 is rotatably connected to the surface of the side plate 211. A gear 213 is fixed to the surface of the rotating shaft 212. The gear 213 meshes with the rack 210. Spray pipes 214 are fixed to both ends of the rotating shaft 212. Multiple nozzles are connected to the surface of the spray pipes 214. A hose 215 is connected to the surface of the delivery pump 202. The hose 215 is connected to the spray pipes 214. A mounting bracket 216 is fixed above the surface of the housing 206.
[0025] During firefighting, the height of the movable plate 205 can be adjusted by activating cylinder 204, thereby changing the height of the sprinkler pipe 214 to accommodate firefighting needs at greater heights. When it is necessary to expand the firefighting range, the motor inside the motor box 207 is activated, causing the reciprocating screw 208 to rotate. This causes the slider 209 to be affected by the thread, driving the rack 210 to move up and down. During this process, the rack 210 drives the gear 213 to rotate back and forth, causing the rotating shaft 212 to drive the sprinkler pipe 214 to rotate back and forth, thus achieving a fan-shaped spraying effect. By rotating within a fan-shaped range, the sprinkler pipe 214 can dynamically change the direction of water spray, expanding the coverage area of the water flow. This design is particularly suitable for irregular spaces or situations requiring all-round firefighting. This design can more effectively reach every corner of the fire scene, reduce firefighting blind spots, and expand the firefighting range.
[0026] Furthermore, the smoke elimination mechanism 3 includes a filter box 301, with an exhaust fan 302 connected to the lower side of the inner wall of the filter box 301 via a pipe, an exhaust pipe 303 connected to the top of the filter box 301, an exhaust shell 304 connected to the surface of the exhaust pipe 303, and the exhaust shell 304 fixedly connected to the surface of the mounting bracket 216. Two filter plates 305 are provided inside the filter box 301.
[0027] When the exhaust fan 302 starts, it can draw air into the filter box 301, creating a negative pressure inside the filter box 301. This allows the exhaust casing 304 to draw in outside smoke, which is then transported to the filter box 301 through the exhaust pipe 303. The smoke is then filtered by the two filter plates 305, ultimately achieving the smoke elimination effect.
[0028] Furthermore, a grille 307 is fixed to the inner wall of the exhaust casing 304, and a filter screen 306 is provided on the upper part of the filter box 301.
[0029] The grille 307 prevents large impurities from being sucked into the exhaust housing 304, while the filter 306 intercepts large particles and impurities in the air, preventing impurities from affecting the normal filtration of the filter 306.
[0030] Furthermore, three U-shaped shells 308 are fixed to the inner wall of the filter box 301. Placement grooves are opened on the surface of the U-shaped shells 308. The filter screen 306 and the filter plate 305 are slidably connected to the placement grooves on the surface of the U-shaped shells 308. A door 309 is hinged to the surface of the filter box 301, and the opening on the surface of the U-shaped shells 308 is aligned with the door 309.
[0031] Both the filter screen 306 and the filter plate 305 are effectively contained within the U-shaped housing 308. When the door 309 is opened, the operator can directly pull out the filter plate 305 or the filter screen 306 from inside the U-shaped housing 308 for cleaning or replacement.
[0032] Furthermore, filter plate 305 is an activated carbon filter plate, and the lower filter plate 305 is an HPEA filter plate;
[0033] Activated carbon filter plates contain numerous micropores and have an extremely high specific surface area, which can effectively adsorb harmful gases in flue gas, reducing the burden on subsequent HEPA filters. HEPA filter plates can efficiently capture and filter out at least 99.97% of particles with a diameter of 0.3 micrometers, including fine soot in flue gas, tiny particles produced by combustion, and microorganisms, achieving deep air purification. When used together, both can achieve comprehensive purification of flue gas, removing not only harmful gases but also particulate matter, creating a safer and healthier breathing environment.
[0034] Furthermore, corrugated pipes 310 are installed on the surfaces of both the extraction pipe 303 and the hose 215;
[0035] When the cylinder 204 moves the movable plate 205, the bellows 310 can extend and retract, thus ensuring the normal transmission of gas and liquid.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
