Description

Technical Field

[0001] The present invention relates to the technical field of dry powder fire extinguishers, and particularly to a smart fire fighting dry powder fire extinguisher. Background Art

[0002] Generally, fire fighting equipment needs to be equipped in indoor buildings. There are a large number of circuits in most indoor buildings. When a fire occurs in the circuit, a dry powder fire extinguisher can effectively and safely extinguish the fire. However, there are still some deficiencies in the existing dry powder fire extinguishers.

[0003] In the prior art, for example, a dry powder fire extinguisher with the publication number CN111821620A. By pulling the pull ring, the lower end of the pull ring slides out of the jack. At this time, the rack slides to the left under the action of the return spring. Then the rack drives the gear to rotate. The gear drives the cross plate to rotate through the hollow sleeve. The cross plate drives the stirring rod to stir and loosen the dry powder in the fire extinguisher. The operation is simpler and faster, and the loosening effect of the dry powder is better. While the stirring rod is stirring, the stirring rod drives the transmission shaft to rotate through the turntable. The transmission shaft will drive the input pipe to rotate. The input pipe will drive the device pipes on both sides to rotate. The sliding rods in the two device pipes slide in opposite directions and separate under the action of centrifugal force. At this time, the input pipe will communicate with the gas storage tank. The high-pressure gas in the gas storage tank will enter the end cover from the input pipe, then enter the nozzle from the end cover through the connecting pipe and the vertical pipe, and be sprayed into the fire extinguisher from the nozzle, so as to disperse the dry powder in the fire extinguisher and make the loosening effect of the dry powder in the fire extinguisher better;

[0004] However, during its use, due to the limited gas stored inside the bottle body and the inability to adjust the gas pressure, when some gas is discharged, the gas pressure inside the bottle body decreases, thereby reducing the impact force on the dry powder, and further greatly affecting the spraying distance of the dry powder, thus affecting the fire extinguishing effect of the fire extinguisher, and there are certain usage defects. Summary of the Invention

[0005] The purpose of the present invention is to provide a smart fire fighting dry powder fire extinguisher to solve the problem in the above background art that in the current market, due to the limited gas stored inside the bottle body of the dry powder fire extinguisher and the inability to adjust the gas pressure, when some gas is discharged, the gas pressure inside the bottle body decreases, thereby reducing the impact force on the dry powder, and further greatly affecting the spraying distance of the dry powder, thus affecting the fire extinguishing effect of the fire extinguisher.

[0013] Preferably, a controller is fixedly arranged at the upper end of the bottle body, a double-headed motor is fixedly installed on the outer side of the controller, roller wheels are fixedly installed at the output ends on both sides of the double-headed motor, and the roller wheels roll inside the guide rail, and the guide rail is fixedly installed by hanging on the building roof.

[0014] By adopting the above technical solution, the double-headed motor is controlled to drive the roller wheels, so that the roller wheels slide along the guide rail, and the position of the bottle body can be adjusted, so that the bottle body can quickly move to the vicinity of the fire point inside the building.

[0015] Preferably, the heat-conducting bin plates are made of copper heat-conducting material, and the two heat-conducting bin plates are respectively located on both sides of the guide rail, and the inner wall of the heat-conducting bin plates is attached to the air storage bag, and the air storage bag is filled with inert gas.

[0016] By adopting the above technical solution, when the bottle body moves to the vicinity of the fire point, the heat-conducting bin plate on the corresponding side of the fire point will quickly absorb heat and conduct the heat to the gas in the air storage bag, causing the gas to expand.

[0017] Preferably, the air storage bag is connected to the elastic air bag on the opposite side through a pipeline, and the pipeline is attached to the outer side of the bottle body, and the elastic air bags are also symmetrically arranged with respect to the guide rail.

[0018] By adopting the above technical solution, after the air storage bag is heated, the expanded gas enters the elastic air bag on the opposite side, so that the corresponding elastic air bag expands and deforms, and then drives the adjusting plate to tilt, so that the nozzle inside the adjusting plate is adjusted in orientation, enabling the nozzle to automatically face near the fire point.

[0019] Preferably, compressed fire extinguishing gas is filled between the partition plate and the piston sheet, the lower surface of the partition plate is attached to the air collecting cover, the air collecting cover is arranged in a funnel-shaped structure, and there is an air duct between the air collecting cover and the impeller.

[0020] By adopting the above technical solution, after the air valve is opened, the compressed gas will enter the air collecting cover through the air valve and blow towards the impeller, causing the impeller to rotate under the action of the wind force, thereby driving the rotating shaft to rotate, enabling the stirring rod to stir the dry powder inside the bottle body and preventing caking from affecting the spraying effect.

[0021] Preferably, the piston sheet is hermetically attached to the inner wall of the bottle body, the piston sheet is threadedly connected to the threaded rod, two guide posts penetrate through the piston sheet symmetrically, the guide posts are fixedly installed on the upper surface of the partition plate, and the piston sheet and the guide posts form a lifting structure.

[0022] By adopting the above technical solution, when the threaded rod rotates, it can drive the piston sheet to move downward through the threaded connection, thereby changing the space between the partition plate and the piston sheet, ensuring the stable air pressure of the gas, and preventing the air pressure in the air valve from decreasing and affecting the spraying of the dry powder.

[0023] Preferably, the movable ring and the guide block form a lifting structure, the guide blocks are uniformly fixedly arranged on the outer side of the bottle body, magnetic sheets are uniformly embedded on the inner wall of the movable ring, and the positions of the magnetic sheets and the magnetic blocks correspond and the magnetic poles are opposite.

[0024] By adopting the above technical solution, during the downward movement of the piston sheet, the magnetic block on its outer side can attract the magnetic sheet, so that the movable ring slides down along the guide post on the outer side of the bottle body.

[0025] Preferably, the heat conducting sheets are uniformly rotatably connected to the outer side of the movable ring, the ends of the heat conducting sheets are attached to the movable ring, the movable ring is attached to the outer wall of the bottle body, a pull rope is wound around the shaft end of the heat conducting sheet, the other end of the pull rope is fixedly connected to the lower end surface of the fixed ring, and the side of the heat conducting sheet close to the bottle body is a wavy surface.

[0026] By adopting the above technical solution, when the movable ring moves downward, the pull rope will pull the heat conducting sheet to rotate and unfold, so that the wavy surface of the heat conducting sheet faces downward, thereby absorbing the heat of the fire point faster and heating the fire extinguishing gas inside the bottle body through heat conduction to ensure the air pressure of the gas.

[0027] Preferably, the through hole is arranged in an annular structure, and the width of the through hole gradually increases and then gradually decreases in the clockwise direction. A fan-shaped shutter is fixedly installed at the lower end of the rotating shaft, and the shutter fits against the baffle and partially covers the through hole.

[0028] By adopting the above technical solution, during the rotation of the rotating shaft, the baffle can be driven to cover different positions of the through hole, so as to realize the breathable area of the through hole, adjust the air pressure ejected from the through hole, make the air pressure change reciprocally, so that the spraying distance of the dry powder has a reciprocal adjustment, realize reciprocating spraying, effectively expand the spraying area of the dry powder, and improve the fire extinguishing effect.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: This intelligent fire-fighting dry powder fire extinguisher can synchronously adjust the air pressure inside it during use to ensure the dry powder ejection pressure, and at the same time can evenly cover the fire point, effectively improving the fire extinguishing effect. The specific content is as follows;

[0030] 1. It is provided with a guide rail, an air storage bag and an elastic air bag. When a fire breaks out inside a building, the controller controls the double-headed motor to start, so that the roller moves along the guide rail, and the bottle body moves to near the fire point. At this time, the heat-conducting bin plate will absorb heat and heat the air storage bag, so that the air pressure inside both the air storage bag and the elastic air bag increases, so that the elastic air bag undergoes elastic deformation, and then pushes the adjusting plate to tilt, so that the nozzle automatically faces the fire point to achieve precise fire extinguishing;

[0031] 2. It is provided with an air collecting hood, an impeller, a movable ring and heat-conducting sheets. When the solenoid valve and the air valve are both opened to extinguish the fire, the high-pressure gas will pass through the air collecting hood, thereby blowing the impeller, so that the impeller drives the stirring rod and the threaded rod to rotate through the rotating shaft, so that the stirring rod can stir the dry powder, and the threaded rod will drive the piston piece to move down, reducing the gas storage space, realizing the preliminary adjustment of the air pressure. As the piston piece moves down, it drives the movable ring to move synchronously through the magnetic force, so that the heat-conducting sheet moves down and rotates, realizing efficient heat conduction, thereby heating the gas inside the bottle body, realizing the further boosting of the gas, ensuring that the dry powder has sufficient ejection pressure, and ensuring the fire extinguishing effect;

[0032] 3. It is provided with a baffle, a through hole and a shutter. When the solenoid valve is opened, the high-pressure air flow will eject the dry powder through the through hole of the baffle. During the rotation of the rotating shaft, the shutter will be driven to rotate synchronously, so that the shutter can cover different positions of the through hole, making the area of the dry powder passing through the through hole change reciprocally, so that the air pressure changes, making the spraying distance of the dry powder have a reciprocal adjustment, making the dry powder evenly sprayed towards the fire point, thereby expanding the spraying area of the dry powder and further improving the fire extinguishing effect.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figure 1-9, the present invention provides a technical solution: a smart fire dry powder fire extinguisher, including a bottle body 1 filled with dry powder. An electromagnetic valve 8 is connected to the lower opening of the bottle body 1, and the lower end of the electromagnetic valve 8 is connected to a nozzle 10 through a hose 9. A controller 2 is fixedly arranged at the upper end of the bottle body 1, and a double-headed motor 3 is fixedly installed outside the controller 2. Output ends on both sides of the double-headed motor 3 are fixedly installed with rollers 4, and the rollers 4 roll inside a guide rail 5. At the same time, the guide rail 5 is fixedly installed by hanging on the roof of a building.

[0045] As Figure 1 shown, when a fire breaks out inside a building, the controller 2 will start to control the double-headed motor 3, thereby driving the rollers 4 to roll along the guide rail 5, so as to adjust the position of the bottle body 1, making the bottle body 1 move near the fire point, facilitating subsequent fire extinguishing operations.

[0046] It further includes: a heat-conducting bin plate 6, fixedly installed on both sides of the bottle body 1, and a gas storage bag 7 is fitted and embedded inside the heat-conducting bin plate 6. A fixing plate 11 is fixedly installed outside the electromagnetic valve 8. An adjusting plate 12 is arranged below the fixing plate 11, and the adjusting plate 12 is fixedly installed outside the nozzle 10. Two elastic air bags 13 are symmetrically bonded and fixed between the fixing plate 11 and the adjusting plate 12. The heat-conducting bin plate 6 is made of copper heat-conducting material, and the two heat-conducting bin plates 6 are respectively located on both sides of the guide rail 5. The inner wall of the heat-conducting bin plate 6 is attached to the gas storage bag 7, and the gas storage bag 7 is filled with inert gas. The gas storage bag 7 is connected to the elastic air bag 13 on the opposite side through a pipeline, and the pipeline is attached to the outside of the bottle body 1. The elastic air bags 13 are also symmetrically arranged with respect to the guide rail 5.

[0047] As Figure 2 and Figure 5 shown, the heat-conducting bin plate 6 on the corresponding side of the fire point will quickly absorb and conduct the nearby heat to the gas storage bag 7 inside it, causing the gases inside both the gas storage bag 7 and the elastic air bag 13 to expand due to heat, so that the elastic air bag 13 expands and deforms. The expanded elastic air bag 13 will push the adjusting plate 12 to tilt and adjust, so that the nozzle 10 can accurately face the fire point, realizing automatic search for the fire point position.

[0048] The partition plate 14 is fixedly installed inside the bottle body 1. Above the partition plate 14, there is a piston piece 15. At the middle position of the partition plate 14, a rotating shaft 18 is rotatably installed. And on the outer side of the rotating shaft 18, an impeller 19 is fixedly installed. At the same time, on the outer side of the impeller 19, a gas collecting hood 17 is fixedly arranged. Moreover, on the outer side of the middle part of the rotating shaft 18, a stirring rod 20 is fixedly arranged. At the top of the rotating shaft 18, a threaded rod 21 is fixedly arranged; a magnetic block 23 is fixedly arranged on the lower surface of the piston piece 15; a movable ring 24 is sleeved on the outer side of the bottle body 1. Inside the inner wall of the movable ring 24, a magnetic sheet 25 is embedded. And on the outer side of the movable ring 24, a heat conducting sheet 28 is rotatably connected. And above the movable ring 24, there is a fixed ring 27 fixedly connected to the bottle body 1. At the same time, a pull rope 29 is wound around the outer side of the shaft end of the heat conducting sheet 28;

[0049] Between the partition plate 14 and the piston piece 15, compressed fire extinguishing gas is filled. And the lower surface of the partition plate 14 is attached to the gas collecting hood 17. And the gas collecting hood 17 is arranged in a funnel-shaped structure. At the same time, there is an air duct between the gas collecting hood 17 and the impeller 19. The piston piece 15 is in sealed fit with the inner wall of the bottle body 1. And the piston piece 15 is in threaded connection with the threaded rod 21. And on the piston piece 15, two guide posts 22 penetrate symmetrically. At the same time, the guide posts 22 are fixedly installed on the upper surface of the partition plate 14. And the piston piece 15 and the guide posts 22 form a lifting structure. The movable ring 24 and the guide block 26 form a lifting structure. And the guide blocks 26 are evenly fixedly arranged on the outer side of the bottle body 1. And on the inner wall of the movable ring 24, magnetic sheets 25 are evenly embedded. At the same time, the positions of the magnetic sheets 25 and the magnetic block 23 correspond and the magnetic poles are opposite. The heat conducting sheets 28 are evenly rotatably connected to the outer side of the movable ring 24. And the end of the heat conducting sheet 28 is attached to the movable ring 24. And the movable ring 24 is attached to the outer wall of the bottle body 1. At the same time, a pull rope 29 is wound around the shaft end of the heat conducting sheet 28. And the other end of the pull rope 29 is fixedly connected to the lower end surface of the fixed ring 27. The side of the heat conducting sheet 28 close to the bottle body 1 is a wavy surface.

[0050] As Figure 2-5 and Figure 8-9 shown, when fire extinguishing is needed, the electromagnetic valve 8 and the air valve 16 are opened, so that the compressed gas above the partition plate 14 enters the gas collecting hood 17 through the air valve 16, thereby impacting the impeller 19, making the impeller 19 drive the rotating shaft 18 to rotate synchronously, so that the stirring rod 20 on the outer side of the middle part of the rotating shaft 18 can stir the dry powder, avoiding the dry powder from sticking and being unable to be ejected. At the same time, the threaded rod 21 will be in threaded connection with the piston piece 15, driving the piston piece 15 to move downward close to the partition plate 14, thereby reducing the space between the two, initially ensuring the gas pressure between the two. At the same time, under the magnetic force of the magnetic block 23 and the magnetic sheet 25, the piston piece 15 drives the movable ring 24 to move downward along the guide block 26. At this time, the pull rope 29 will pull the heat conducting sheet 28 to rotate and unfold, so that the heat conducting sheet 28 can quickly absorb heat and conduct the heat to the gas in the bottle body 1, thereby further realizing the pressure increase of the gas and ensuring the continuous ejection pressure of the dry powder.

[0051] The baffle 30 is fixedly arranged in the lower opening of the bottle body 1, and a through hole 31 is formed in the baffle 30. The through hole 31 is arranged in an annular structure, and the width of the through hole 31 gradually increases and then gradually decreases in the clockwise direction. And a sector-shaped cover piece 32 is fixedly installed at the lower end of the rotating shaft 18. At the same time, the cover piece 32 fits on the baffle 30 and partially covers the through hole 31, as Figure 5-7 shown, the high-pressure gas will carry the dry powder through the through hole 31 into the spray head 10 and spray out. At the same time, the rotating shaft 18 will drive the cover piece 32 to rotate synchronously, so that the cover piece 32 can cover different positions of the through hole 31, causing the opening area of the through hole 31 to change reciprocally. At this time, the air pressure of the spray head 10 changes, and then the spraying distance of the dry powder near the fire point is adjusted reciprocally, thereby expanding the spraying area of the dry powder and further improving the fire extinguishing effect.

[0052] Working principle: When using this intelligent fire-fighting dry powder fire extinguisher, first, as Figure 1-9 shown, when a fire breaks out, the double-headed motor 3 drives the roller 4 to drive the bottle body 1 to move near the fire point. At this time, the gas inside the storage airbag 7 will expand due to heat, and then the elastic airbag 13 is used to adjust the orientation of the spray head 10, so that the spray head 10 faces the fire point. The electromagnetic valve 8 and the air valve 16 are opened, so that the high-pressure gas carries the dry powder and sprays it towards the fire point. At the same time, the stirring rod 20 can loosen the dry powder, and the piston piece 15 and the movable ring 24 will be adjusted synchronously to ensure the air pressure inside the bottle body 1. And the cover piece 32 will cover different positions of the through hole 31, causing the wind speed of the through hole 31 to change reciprocally, so that the spraying distance of the dry powder is adjusted reciprocally, increasing the spraying area of the dry powder, and achieving efficient fire extinguishing, thus completing a series of operations.
