Description

Technical Field

[0001] This utility model relates to the technical field of foam fire extinguishing devices, specifically a high-efficiency and environmentally friendly foam fire extinguishing device. Background Technology

[0002] Foam fire extinguishing systems mainly consist of foam liquid storage tanks, spray guns, proportioning mixers, hoses, and wheeled chassis. It is a new type of environmentally friendly and highly efficient foam fire extinguishing system, characterized by rapid and simple operation, high flexibility, and high reliability. In the early stages of a fire, the system can be easily and flexibly propelled to the fire scene for extinguishing.

[0003] However, existing environmentally friendly and efficient foam fire extinguishing devices have drawbacks during use. When the user holds the spray gun, foam will splash out from the spray gun. If the user does not wear appropriate protective equipment, they may inhale harmful gases or be covered by foam, which may affect breathing and vision, causing blurred vision, or even damage to the cornea in extreme cases. In order to address the above problems, the inventor proposes a high-efficiency and environmentally friendly foam fire extinguishing device to solve the above problems. Utility Model Content

[0004] To address the problems of limited application range and low extinguishing efficiency caused by the inability to adjust the spray height of the nozzle according to the actual ignition point in the use of environmentally friendly and efficient foam fire extinguishing devices, the purpose of this utility model is to provide a high-efficiency and environmentally friendly foam fire extinguishing device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a high-efficiency and environmentally friendly foam fire extinguishing device, comprising a fire extinguishing device body, the fire extinguishing device body comprising a base plate, a foam liquid storage tank, a proportioning mixer and a suction pipe, the foam liquid storage tank being located on the top surface of the base plate, the proportioning mixer being fixedly disposed on the outer surface of the foam liquid storage tank, the suction pipe being fixedly disposed between the foam liquid storage tank and the proportioning mixer, a fixing hoop being fixedly disposed on the top surface of the adjusting plate, and a spray gun being fixedly disposed inside the fixing hoop;

[0006] A fixed plate is provided above the base plate, and an adjusting plate is provided above the fixed plate. A first motor is installed on one side of the fixed plate. A threaded rod is fixedly provided at the output end of the first motor. A threaded block is threadedly fitted on the outer surface of the threaded rod. A movable plate is fixedly provided on the top surface of the threaded block. An ear plate is fixedly provided on the top surface of the movable plate. A rotating shaft is fixedly provided inside the ear plate. A rotating roller is rotatably fitted on the outer surface of the rotating shaft. An inclined plate is fixedly provided on the bottom surface of the adjusting plate. The rotating roller is attached to the bottom surface of the inclined plate. A sliding groove is opened in the fixed plate, and the threaded block slides in the sliding groove. A fixing ear is fixedly provided on the top surface of the fixed plate. A rotating rod is fixedly connected between the ears. A fixed seat is fixedly provided on the bottom surface of the adjusting plate. The fixed seat is rotatably sleeved on the outer surface of the rotating rod. First, take one of the hoses out of the toolbox, then connect one end of the hose to one end of the proportioning mixer, and then connect the other end to the fire hydrant or pressurized water source. Then connect the two ends of the other hose to the proportioning mixer and the spray gun respectively. Turn on the water source. When the high-pressure water flows through the proportioning mixer at high speed, a vacuum (negative pressure) is formed inside the proportioning mixer due to the lateral movement and diffusion of the jet particles. At this time, the foam liquid in the foam liquid storage tank is sucked into the proportioning mixer through the suction pipe under atmospheric pressure. The foam liquid and pressurized water are mixed in a certain proportion in the proportioning mixer to form a foam mixture. When the foam mixture flows through the foam spray gun, the performance of the spray gun will draw in a certain amount of air, causing the mixture to foam and form foam. Then the foam is sprayed to the fire scene through the spray gun.

[0007] By activating the first motor, the threaded rod rotates, causing the threaded block to move the moving plate, which in turn moves the ear plate. This causes the rotating shaft to drive the rotating roller to contact the inclined surface at the lower end of the inclined plate and roll on the inclined surface. This causes the adjusting plate to drive the fixed seat to rotate on the outer surface of the rotating rod, thereby adjusting the angle of the spray gun so that the spray gun can extinguish the fire. By activating the second motor, the connecting rod rotates, causing the connecting rod to drive the gear to rotate. The gear meshes with the toothed plate, causing the toothed plate to drive the support rod to slide inside the sleeve. The support rod drives the fixed plate to rise, thereby adjusting the height of the spray gun to suit different fire locations, increasing the extinguishing range and accelerating the extinguishing efficiency.

[0008] Preferably, a sleeve is fixedly provided on the top surface of the base plate, a support rod is slidably inserted into the sleeve, the support rod is fixedly provided on the bottom surface of the fixed plate, a fixed frame is fixedly provided on the outer surface of the sleeve, a connecting rod is rotatably inserted into the fixed frame, a second motor is installed at one end of the fixed frame, the output end of the second motor is fixedly connected to the connecting rod, a gear is fixedly sleeved on the outer surface of the connecting rod, a toothed plate is fixedly provided in the support rod, the gear meshes with the toothed plate, a groove is opened in the support rod, and the toothed plate is fixedly provided in the groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The fixed base is rotated on the outer surface of the rotating rod by the adjustment plate, which can adjust the angle of the spray gun. The spray gun can then be used to extinguish the fire without people having to hold the spray gun. This avoids foam splashing into the eyes or harmful gases entering the body and will not cause injury to people.

[0011] 2. The support rod slides inside the sleeve, causing the fixed plate to rise, thereby adjusting the height of the spray gun to suit different fire locations, increasing the fire extinguishing range and accelerating the fire extinguishing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5 As shown, this utility model provides a high-efficiency and environmentally friendly foam fire extinguishing device, including a fire extinguishing device body 1. The fire extinguishing device body 1 includes a base plate 101, a foam liquid storage tank 11, a proportioning mixer 12, and a suction pipe 13. The foam liquid storage tank 11 is located on the top surface of the base plate 101. The proportioning mixer 12 is fixedly installed on the outer surface of the foam liquid storage tank 11. The suction pipe 13 is fixedly installed between the foam liquid storage tank 11 and the proportioning mixer 12. A fixing hoop 17 is fixedly installed on the top surface of the adjusting plate 27. A spray gun 18 is fixedly installed inside the fixing hoop 17. An inlet pipe 14 is provided on the outer surface of the foam liquid storage tank 11. A toolbox 15 is fixedly installed on the top surface of the base plate 101. Two water hoses 16 are placed inside toolbox 15. One water hose 16 is taken out of toolbox 15 and connected to one end of proportioner 12. The other end is connected to a fire hydrant or pressurized water source. The two ends of the other water hose 16 are connected to proportioner 12 and spray gun 18 respectively. When the water source is turned on, when the high-pressure water flows through proportioner 12 at high speed, a vacuum (negative pressure) is formed inside proportioner 12 due to the lateral movement and diffusion of the jet particles. At this time, the foam liquid in foam liquid storage tank 11 is sucked into proportioner 12 through suction pipe 13 under atmospheric pressure. The foam mixture is mixed with pressurized water in a certain proportion in the proportioner 12 to form a foam mixture. When the foam mixture flows through the foam spray gun 18, the performance of the spray gun 18 will draw in a certain amount of air, causing the mixture to foam and form foam. Then the foam is sprayed through the spray gun 18 to the fire scene, covering the surface of the burning material, and extinguishing the fire by means of cooling, isolating oxygen and suppressing steam.

[0021] A fixed plate 2 is provided above the base plate 101, and an adjusting plate 27 is provided above the fixed plate 2. A first motor 21 is installed on one side of the fixed plate 2. A threaded rod 211 is fixedly provided at the output end of the first motor 21. A threaded block 22 is threadedly fitted on the outer surface of the threaded rod 211. A movable plate 23 is fixedly provided on the top surface of the threaded block 22. An ear plate 24 is fixedly provided on the top surface of the movable plate 23. A rotating shaft 25 is fixedly provided inside the ear plate 24. A rotating roller 26 is rotatably fitted on the outer surface of the rotating shaft 25. An inclined plate 28 is fixedly provided on the bottom surface of the adjusting plate 27. The rotating roller 26 is attached to the bottom surface of the inclined plate 28. A sliding groove 201 is provided inside the fixed plate 2. The threaded block 22 is slidably disposed in the sliding groove 201. A fixed ear 29 is fixedly provided on the top surface of the fixed plate 2. The fixed ears 29 are fixedly connected to each other. A rotating rod 291 is connected to a fixed base 292 fixed on the bottom surface of an adjusting plate 27. The fixed base 292 is rotatably sleeved on the outer surface of the rotating rod 291. By turning on the first motor 21, the threaded rod 211 is rotated, which causes the threaded block 22 to move the moving plate 23, which in turn causes the moving plate 23 to move the ear plate 24. This causes the rotating shaft 25 to drive the rotating roller 26 to fit against the inclined surface at the lower end of the inclined plate 28 and roll on the inclined surface of the inclined plate 28. This causes the adjusting plate 27 to drive the fixed base 292 to rotate on the outer surface of the rotating rod 291, thereby enabling the angle of the spray gun 18 to be adjusted. Thus, the spray gun 18 can extinguish the fire without people needing to hold the spray gun 18, avoiding foam splashing into the eyes or harmful gases entering the body, and preventing injury to people.

[0022] A sleeve 3 is fixedly installed on the top surface of the base plate 101. A support rod 31 is slidably inserted into the sleeve 3. The support rod 31 is fixedly installed on the bottom surface of the fixed plate 2. A fixed frame 33 is fixedly installed on the outer surface of the sleeve 3. A connecting rod 34 is rotatably inserted into the fixed frame 33. A second motor 35 is installed at one end of the fixed frame 33. The output end of the second motor 35 is fixedly connected to the connecting rod 34. A gear 36 is fixedly sleeved on the outer surface of the connecting rod 34. A toothed plate 32 is fixedly installed in the support rod 31. The gear 36 meshes with the toothed plate 32. A groove 311 is opened in the support rod 31. The toothed plate 32 is fixedly installed in the groove 311.

[0023] By adopting the above technical solution, the second motor 35 is turned on, causing the connecting rod 34 to rotate. The connecting rod 34 drives the gear 36 to rotate, and the gear 36 meshes with the toothed plate 32 for transmission. This causes the toothed plate 32 to drive the support rod 31 to slide inside the sleeve 3. The support rod 31 drives the fixed plate 2 to rise, thereby enabling the height of the spray gun 18 to be adjusted to suit different fire locations, increase the fire extinguishing range, and accelerate the fire extinguishing efficiency.

[0024] Working principle: First, take one of the hoses 16 out of the toolbox 15. Then, connect one end of the hose 16 to one end of the proportioner 12, and the other end to a fire hydrant or pressurized water source. Then, connect the two ends of the other hose 16 to the proportioner 12 and the spray gun 18 respectively. Turn on the water source. When the high-pressure water flows through the proportioner 12 at high speed, a vacuum (negative pressure) is formed inside the proportioner 12 due to the lateral movement and diffusion of the jet particles. At this time, the foam liquid in the foam liquid storage tank 11 is drawn into the proportioner 12 through the suction pipe 13 under atmospheric pressure. The foam liquid and pressurized water are mixed in a certain proportion in the proportioner 12 to form a foam mixture. When the foam mixture flows through the foam spray gun 18, the performance of the spray gun 18 will draw in a certain amount of air, causing the mixture to foam and form foam. Then, the foam is sprayed to the fire scene through the spray gun 18.

[0025] By activating the first motor 21, the threaded rod 211 rotates, causing the threaded block 22 to move the moving plate 23. The moving plate 23 then moves the ear plate 24, causing the rotating shaft 25 to drive the rotating roller 26 to adhere to the inclined surface at the lower end of the inclined plate 28 and roll on the inclined surface of the inclined plate 28. This causes the adjusting plate 27 to drive the fixed seat 292 to rotate on the outer surface of the rotating rod 291, thereby enabling the angle of the spray gun 18 to be adjusted so that the spray gun 18 can extinguish the fire. By activating the second motor 35, the connecting rod 34 rotates, causing the connecting rod 34 to drive the gear 36 to rotate. The gear 36 meshes with the toothed plate 32, causing the toothed plate 32 to drive the support rod 31 to slide inside the sleeve 3. The support rod 31 drives the fixed plate 2 to rise, thereby enabling the height of the spray gun 18 to be adjusted so that it can be used for fires in different locations, increasing the fire extinguishing range and accelerating the fire extinguishing efficiency.
