A fire-fighting smoke purification device for high-rise buildings

Abstract

This invention discloses a fire-fighting smoke purification and treatment device for high-rise buildings, relating to the field of fire smoke treatment technology. It includes a housing with a rotating pipe rotatably connected to it, and a sliding pipe slidably connected to the rotating pipe. Through the arrangement of a water spray unit, a drive unit moves the sliding pipe and a fixed block. The movement of the fixed block moves a sliding rod outward, which in turn extends a telescopic frame. This extension causes multiple first nozzles to extend at equal intervals until a second nozzle sprays water. The movement of the sliding pipe moves a fixed ring upward, which, through a connecting rod, causes a rotating bar to rotate. This causes the rotating bar to unfold, leading to the unfolding of an elastic cloth until the rotating bar contacts the inner wall of the housing. The elastic cloth forms a conical hood, which concentrates the smoke. This increases the spray range and the number of nozzles, and effectively concentrates and purifies the smoke, thereby improving the smoke purification effect.

Description

Technical Field

[0001] This invention relates to the field of fire smoke treatment technology, and in particular to a fire smoke purification and treatment device for high-rise buildings. Background Technology

[0002] With the rapid development of high-rise buildings in cities, the internal structures of these buildings are becoming increasingly complex, with dense populations and equipment. In the event of a fire, smoke often becomes one of the main factors threatening people's lives and hindering fire rescue operations. Fire smoke contains a large amount of toxic and harmful gases, high-temperature particulate matter, and low-visibility aerosols. If not dealt with promptly and effectively, it can easily cause asphyxiation and poisoning, and seriously affect evacuation and firefighting efficiency.

[0003] A search revealed Chinese patent CN118558089B, which discloses a fire-fighting smoke treatment device for high-rise buildings. The device includes a housing and a high-voltage ionization device, and further comprises: an inlet mechanism for introducing smoke into the housing; a dust suppression mechanism for spraying water from top to bottom inside the housing; a filtration mechanism, comprising multiple filtration mechanisms for layered filtration of smoke particles entering the housing; and a tilting cleaning mechanism for cleaning and discharging the particulate impurities filtered out by the filtration mechanisms.

[0004] Based on the above research and existing technology, it was found that: Existing fire smoke purification devices, during water spraying for dust suppression, suffer from uneven purification and low efficiency due to the fixed nozzle positions and limited coverage, making it difficult to adapt to dynamic changes in spatial height and smoke concentration. Smoke tends to diffuse during purification, lacking an effective gathering structure, causing some smoke to escape without adequate treatment, affecting the overall purification effect. Most devices lack the ability to dynamically adjust the smoke introduction process, failing to achieve uniform distribution of smoke in the purification medium (such as water), thus reducing the contact efficiency between smoke and the purification medium per unit time. Furthermore, the mechanical structure for smoke purification is often relatively simple, lacking a coordinated adjustment mechanism, making it impossible to achieve synergistic optimization between spray range, nozzle density, and smoke gathering effect.

[0015] This invention provides an improved fire-fighting smoke purification device for high-rise buildings, which has the following improvements and advantages compared with the prior art: Firstly, this invention, through the setting of the water spray unit, drives the sliding tube and the fixed block to move. The movement of the fixed block causes the sliding rod to move outward, which in turn causes the telescopic frame to extend. The extension of the telescopic frame causes multiple first nozzles to extend at equal intervals. The increased distance between two first nozzles causes the telescopic tube to extend until the through hole moves to the position of the second nozzle, at which point the second nozzle sprays water. The movement of the sliding tube causes the fixed ring to move upward, and the movement of the fixed ring causes the rotating bar to rotate via the connecting rod. This causes the rotating bar to unfold, which in turn unfolds the elastic cloth until the rotating bar contacts the inner wall of the housing, causing the elastic cloth to form a conical hood. The conical hood can concentrate the smoke, thereby increasing the water spray range and the number of nozzles, and concentrating and purifying the smoke, thus improving the smoke purification effect.

[0016] Secondly, the present invention, through the setting of the reciprocating unit, the rotation of the annular shell drives the rotation of the annular rack, the rotation of the annular rack drives the rotation of the gear, the rotation of the gear drives the rotation of the connecting pipe, the fixed pipe and the movable bar, the rotation of the movable bar drives the rotation of the cylindrical rod, and the rotation of the cylindrical rod drives the T-shaped rod and the L-shaped tube to reciprocate, thereby enabling the smoke to be evenly placed into the water for purification.

[0017] Thirdly, this invention, through the setting of the extrusion unit, uses a rotating rod to drive the extrusion block to rotate. The rotating extrusion block extrudes the inclined block downwards, and the movement of the inclined block drives the movable column and the annular piston downwards. The movement of the annular piston forces the oil in the annular shell into the fixed shell through the bent pipe. Then, the oil is squeezed into the fixed pipe through the mounting hole and connecting pipe. The oil entering the fixed pipe extrudes the movable bar and the cylindrical rod, thereby increasing the radius of the cylindrical rod and thus increasing the moving distance of the L-shaped pipe, improving the purification effect of water on smoke.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides an improved fire-fighting smoke purification device for high-rise buildings. The technical solution of this invention is as follows: like Figures 1 to 9 As shown, this embodiment of the invention provides a fire-fighting smoke purification and treatment device for high-rise buildings, including a housing 1, a rotating pipe 11 rotatably connected to the housing 1, a sliding pipe 12 slidably connected to the rotating pipe 11, and further comprising: The smoke purification mechanism is located on housing 1; The smoke purification mechanism includes a water spray unit, a drive unit, a reciprocating unit, and a compression unit.

Two rotating rods 15 are rotatably connected to the annular shell 41. Sliding rods 14 are slidably connected to each of the two rotating rods 15. Two fixing blocks 13 are fixedly connected to the bottom end of the sliding tube 12. One end of each of the two sliding rods 14 is rotatably connected to the two fixing blocks 13. A telescopic frame 16 is mounted on both the sliding rods 14 and the rotating rods 15. Multiple first nozzles 17 are fixedly connected to each of the two telescopic frames 16. A telescopic pipe 18 is fixedly connected to two adjacent first nozzles 17. A three-way pipe 110 is fixedly connected to the bottom end of the sliding pipe 12. Two flexible hoses 19 are fixedly connected to both ends of the three-way pipe 110. One end of each flexible hose 19 is fixedly connected to one of the first nozzles 17. An annular block 21 is fitted onto the sliding pipe 12. Multiple rotating bars 22 are rotatably connected to the annular block 21.

One end of each of the multiple connecting rods 23 is rotatably connected to the fixed ring 24. An elastic cloth 25 is fixedly connected to two adjacent rotating bars 22. Through the setting of the water spray unit, the drive unit drives the sliding tube 12 and the fixed block 13 to move. The movement of the fixed block 13 drives the sliding rod 14 to move outward. The movement of the sliding rod 14 drives the telescopic frame 16 to extend. The extension of the telescopic frame 16 drives the multiple first nozzles 17 to extend at equal intervals. The increase in the distance between two first nozzles 17 drives the telescopic tube 18 to extend until the through hole 112 moves to... When the second nozzle 111 is in position, the second nozzle 111 sprays water. The sliding tube 12 moves, causing the fixed ring 24 to move upward. The movement of the fixed ring 24 drives the rotating bar 22 to rotate through the connecting rod 23, causing the rotating bar 22 to unfold and drive the elastic cloth 25 to unfold until the rotating bar 22 contacts the inner wall of the housing 1, so that the elastic cloth 25 forms a cone-shaped hood. The cone-shaped hood can concentrate the smoke, thereby increasing the spray range and the number of nozzles, and can concentrate the smoke for water purification, thus improving the purification effect of the smoke.

[0023] Furthermore, each of the multiple telescopic pipes 18 is fixedly connected to a second nozzle 111, and each of the multiple telescopic pipes 18 is provided with a through hole 112. The top end of the rotating pipe 11 is rotatably connected to a water inlet pipe 61, and a fixing plate 6 is fixedly connected to the housing 1. The water inlet pipe 61 is fixedly connected to the fixing plate 6, and an air outlet pipe 7 is fixedly connected to the housing 1. Through the water inlet pipe 61, water enters the rotating pipe 11 through the water inlet pipe 61, and then enters the first nozzle 17 through the sliding pipe 12, the three-way pipe 110, and the flexible hose 19. Then, it enters the multiple first nozzles 17 through the telescopic pipes 18 and is sprayed out by the first nozzles 17. The sprayed water mist can perform secondary purification of the smoke. The setting of the fixing plate 6 improves the stability of the water inlet pipe 61.

[0024] Furthermore, two fixing rods 2 are fixedly connected to the inner wall of the box 1, and the ends of the two fixing rods 2 that are close to each other are fixedly connected to the annular block 21; the fixing rods 2 are fixed by setting them.

The two bevel gears 114 mesh with each other. Through the motor 113, the motor 113 drives the rotating tube 11 and the sliding tube 12 to rotate via the two bevel gears 114. The rotation of the sliding tube 12 drives the fixed block 13, the sliding rod 14, the rotating rod 15 and the annular shell 41 to rotate. The rotating rod 15 rotates the telescopic frame 16, the first nozzle 17, the telescopic tube 18 and the second nozzle 111 to rotate, so that the first nozzle 17 can rotate to spray water, thereby spraying water evenly and improving the purification effect of smoke.

[0026] Furthermore, the drive unit includes a hydraulic cylinder 3 fixedly connected to the housing 1. A fixing bar 31 is fixedly connected to the output end of the hydraulic cylinder 3. A connecting plate 33 is rotatably connected to the sliding tube 12. Sliding columns 32 are fixedly connected to both ends of the connecting plate 33. Both sliding columns 32 are slidably connected to the housing 1. One end of the fixing bar 31 is fixedly connected to the top of one of the sliding columns 32. By setting up the drive unit, starting the hydraulic cylinder 3 drives the fixing bar 31 to move upward. The movement of the fixing bar 31 drives the sliding column 32 and the connecting plate 33 to move. The movement of the connecting plate 33 drives the sliding tube 12 and the fixing block 13 to move, thereby realizing the upward movement of the sliding tube 12.

[0027] Furthermore, the reciprocating unit includes a protective cover 412 fixedly connected to the housing 1, the protective cover 412 being rotatably connected to the annular shell 41, a connecting pipe 44 being rotatably connected to the protective cover 412, a gear 43 being fixedly connected to the top end of the connecting pipe 44, a circular ring rack 42 being fixedly connected to the annular plate 4, the circular ring rack 42 and the gear 43 meshing, a fixed pipe 45 being fixedly connected to the bottom end of the connecting pipe 44, a movable bar 46 being slidably connected to the fixed pipe 45, a cylindrical rod 47 being fixedly connected to one end of the movable bar 46, an air inlet pipe 410 being fixedly connected to the housing 1, and an air inlet pipe 410 being... An L-shaped tube 49 is slidably connected, and a T-shaped rod 48 is fixedly connected to the L-shaped tube 49. A strip groove is opened on the T-shaped rod 48, and the bottom end of the cylindrical rod 47 extends into the strip groove. Through the setting of the reciprocating unit, the rotation of the annular shell 41 drives the rotation of the annular rack 42, the rotation of the annular rack 42 drives the rotation of the gear 43, the rotation of the gear 43 drives the rotation of the connecting tube 44, the fixed tube 45 and the movable bar 46, the rotation of the movable bar 46 drives the rotation of the cylindrical rod 47, and the rotation of the cylindrical rod 47 drives the T-shaped rod 48 and the L-shaped tube 49 to reciprocate, thereby enabling the smoke to be evenly placed into the water for purification.

[0028] Furthermore, the extrusion unit includes two movable columns 5 slidably connected to the annular shell 41. A circular piston 54 is fixedly connected to the bottom end of both movable columns 5. The circular piston 54 is slidably connected to the annular shell 41. A bent tube 55 is fixedly connected to the protective cover 412. The top end of the bent tube 55 is fixedly connected to the annular plate 4. The bottom end of the bent tube 55 is fixedly connected to a fixed shell 56, which is rotatably connected to the connecting pipe 44. An inclined block 51 is fixedly connected to the top end of each of the two movable columns 5. An extrusion block 52 is fixedly connected to each of the two rotating rods 15. The two extrusion blocks 52 are in contact with the two inclined blocks 51 respectively. An installation hole 411 is provided on the connecting pipe 44. The mounting hole 411 is located inside the fixed shell 56. Through the setting of the extrusion unit, the rotating rod 15 rotates to drive the extrusion block 52 to rotate. The rotating extrusion block 52 extrudes the inclined block 51 to move downward. The movement of the inclined block 51 drives the movable column 5 and the annular piston 54 to move downward. The movement of the annular piston 54 squeezes the oil in the annular shell 41 into the fixed shell 56 through the bent pipe 55. Then the oil is squeezed into the fixed pipe 45 through the mounting hole 411 and the connecting pipe 44. The oil entering the fixed pipe 45 squeezes the movable bar 46 and the cylindrical rod 47 to move, thereby increasing the radius of the cylindrical rod 47, thus increasing the moving distance of the L-shaped pipe 49 and improving the purification effect of water on smoke.

[0029] Furthermore, each of the two movable columns 5 is fitted with a compression spring 53, and the two ends of the compression spring 53 are fixedly connected to the inclined block 51 and the annular shell 41, respectively. By setting the compression spring 53, the compression spring 53 can drive the inclined block 51 and the movable column 5 to reset.

[0030] Specific implementation steps: A certain amount of water is placed at the bottom of the housing 1, with the water outlet of the L-shaped pipe 49 located in the water. Smoke and air are introduced into the water through the air inlet pipe 410 and the L-shaped pipe 49, allowing the water to perform initial purification of the smoke. Incompletely purified air rises from the water. The water enters the rotating pipe 11 through the water inlet pipe 61, then enters the first nozzle 17 through the sliding pipe 12, the three-way pipe 110, and the flexible hose 19. It then enters multiple first nozzles 17 through the telescopic pipe 18 and is sprayed out by the first nozzles 17. The sprayed water mist can perform secondary purification of the smoke. The motor 113 drives the rotating pipe 11 and the sliding pipe 12 to rotate through two bevel gears 114. The rotation of the sliding pipe 12 drives the fixed block 13, the sliding rod 14, the rotating rod 15, and the annular shell. 41. Rotating the rotating rod 15 causes the telescopic frame 16, the first nozzle 17, the telescopic tube 18, and the second nozzle 111 to rotate, enabling the first nozzle 17 to rotate and spray water evenly, thereby improving the purification effect on the smoke. The hydraulic cylinder 3 is activated, causing the fixing bar 31 to move upwards. The movement of the fixing bar 31 causes the sliding column 32 and the connecting plate 33 to move. The movement of the connecting plate 33 causes the sliding tube 12 and the fixing block 13 to move. The movement of the fixing block 13 causes the sliding rod 14 to move outwards. The movement of the sliding rod 14 causes the telescopic frame 16 to extend. The extension of the telescopic frame 16 causes multiple first nozzles 17 to extend at equal intervals. The increased distance between two first nozzles 17 causes the telescopic tube 18 to extend until the through hole 112 moves to the position of the second nozzle 111. When the second nozzle 111 sprays water, the sliding tube 12 moves, causing the fixed ring 24 to move upward. The movement of the fixed ring 24 drives the rotating bar 22 to rotate via the connecting rod 23, causing the rotating bar 22 to unfold and the elastic cloth 25 to unfold until the rotating bar 22 contacts the inner wall of the housing 1, so that the elastic cloth 25 forms a conical hood. The conical hood can concentrate the smoke, thereby increasing the spray range and the number of nozzles, and can concentrate and purify the smoke, thus improving the purification effect. The rotation of the annular shell 41 drives the circular ring rack 42 to rotate, the rotation of the circular ring rack 42 drives the gear 43 to rotate, the rotation of the gear 43 drives the connecting tube 44, the fixed tube 45 and the movable bar 46 to rotate, and the rotation of the movable bar 46 drives the cylindrical rod 47 to rotate. The rotating cylindrical rod 47 drives the T-shaped rod 48 and L-shaped tube 49 to reciprocate, thus evenly distributing the smoke into the water for purification. The rotating rod 15 drives the squeezing block 52 to rotate, squeezing the inclined block 51 downwards. The movement of the inclined block 51 drives the movable column 5 and the annular piston 54 downwards. The movement of the inclined block 51 compresses the squeezing spring 53, causing it to undergo elastic deformation. The movement of the annular piston 54 forces the oil in the annular shell 41 into the fixed shell 56 through the bent pipe 55. Then, the oil is squeezed into the fixed tube 45 through the mounting hole 411 and the connecting pipe 44. The oil entering the fixed tube 45 squeezes the movable bar 46 and the cylindrical rod 47, thereby increasing the radius of the cylindrical rod 47 and thus increasing the moving distance of the L-shaped tube 49.This improves the water's purification effect on the smoke, and the purified air is discharged from the exhaust pipe 7.
