Description

Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, and in particular to a cabinet-type heptafluoropropane gas fire extinguishing device. Background Art

[0002] The cabinet-type HFC-227ea gas fire extinguishing device is mainly composed of a cabinet, a storage bottle, a bottle head valve, a starting electromagnetic device, a pressure signal device, a spray pipe, a nozzle and other components. In addition, it is usually used in conjunction with fire detectors, gas fire extinguishing alarm controllers, etc. to achieve automatic or electrical manual control. When a fire occurs, the fire detector will quickly identify the source of the fire and send out an alarm signal. Subsequently, the starting electromagnetic device will open the bottle head valve to release the HFC-227ea gas in the storage bottle. These gases will quickly spread to the surrounding area of ​​the fire source through the spray pipe and nozzle, forming a protective circle to prevent the fire from spreading. At the same time, the HFC-227ea gas can quickly penetrate flames and smoke to extinguish the fire.

[0003] Chinese patent CN218458509U discloses a "cabinet-type heptafluoropropane gas fire extinguishing device", comprising a cabinet, a partition is installed inside the cabinet, a movable support plate is installed on the top of the partition, a positioning assembly is installed on the movable support plate, a fire extinguishing agent storage bottle is installed on the positioning assembly, and an adjustment mechanism is installed at the bottom of the cabinet; this patent can facilitate the removal of the movable support plate during use, so that the staff can better place and replace the fire extinguishing agent storage bottle, thereby effectively avoiding the problem of affecting the staff's operation due to the relatively small space in the cabinet.

[0004] However, the prior art has the following problems:

[0005] 1. In the prior art, when spraying heptafluoropropane gas, the nozzle is usually fixed, so that the heptafluoropropane gas is continuously sprayed at a fixed angle, resulting in a problem that the heptafluoropropane gas has a small diffusion range in the room when extinguishing the fire. When the indoor fire range is large, due to the small diffusion range of the heptafluoropropane gas, some fire sources may not be extinguished in time.

[0006] 2. Since the fire extinguishing device may have been placed for a long time before it is activated, some sediment may accumulate in the pipeline of the fire extinguishing device, which may cause local pipeline blockage, resulting in the air output being affected when it is activated, thereby affecting the fire extinguishing efficiency.

Example

[0038] See also Figure 1 - Figure 7A cabinet-type heptafluoropropane gas fire extinguishing device comprises: a cabinet 1, a tank 2 is installed in the cabinet 1, a front door 12 is installed on the front side of the cabinet 1, a front plate 10 is installed on the front side of the cabinet 1, a mounting groove 11 is arranged on the front plate 10, the front plate 10 is located above the front door 12, a bottle head valve 3 is installed on the top of the tank 2, a solenoid valve 4 is connected to the top of the bottle head valve 3, a receiver 9 is installed inside the cabinet 1, the receiver 9 is connected to the solenoid valve 4 through a wire, the bottle head valve 3 is connected to the gas pipe 5, the cabinet 1 is installed indoors, when a fire occurs indoors, the fire alarm transmits a signal to the receiver 9, the receiver 9 controls the solenoid valve 4 to open, and the solenoid valve 4 is opened to drive the bottle head valve 3 to open, so that the heptafluoropropane gas in the tank 2 is discharged. Fluoropropane gas enters the air pipe 5 through the bottle head valve 3; the injection assembly 6 is used to inject heptafluoropropane gas, and the injection assembly 6 includes a gas chamber 61, which is installed on the top of the inner wall of the cabinet 1, and the gas chamber 61 is connected to the end of the air pipe 5 away from the bottle head valve 3. A rotating shaft 62 is rotatably installed on the inner wall of the cabinet 1, and the rotating shaft 62 passes through the gas chamber 61. The rotating shaft 62 is rotatably connected to the gas chamber 61, and a wind wheel 63 is connected to the rotating shaft 62. The wind wheel 63 is located inside the gas chamber 61. A ball slider 65 is slidably installed on the top of the inner wall of the cabinet 1, and a reciprocating thread groove 64 is provided on the rotating shaft 62. The inner wall of the ball slider 65 is slidably connected to the reciprocating thread groove 64 through a ball. When the heptafluoropropane gas passes through the gas chamber 61, the gas pushes The moving wind wheel 63 rotates, and the wind wheel 63 drives the rotating shaft 62 to rotate. When the rotating shaft 62 rotates, the cooperation between the reciprocating thread groove 64 and the ball drives the ball slider 65 to slide back and forth left and right. The side of the ball slider 65 close to the front door 12 is connected to a lever 66. The end of the air chamber 61 away from the air pipe 5 is connected to a hose 610. The end of the hose 610 away from the air chamber 61 is connected to a fixed pipe 69. The outer wall of the fixed pipe 69 is connected to a sliding shaft 67. The end of the fixed pipe 69 away from the hose 610 is rotatably connected to a rotating nozzle 611. The heptafluoropropane gas in the air pipe 5 is sequentially transported to the rotating nozzle 611 through the air chamber 61, the hose 610, and the fixed pipe 69. The outer wall of the air chamber 61 close to the front plate 10 is connected to the rotating nozzle 611.

The sliding shaft 67 is slidably connected with the sliding groove of the lever 66. The curved groove plate 68 is provided with a sliding groove, and the sliding shaft 67 is also slidably connected with the sliding groove of the curved groove plate 68. When the lever 66 moves back and forth, the sliding shaft 67 is moved through the sliding groove above it, so that the sliding shaft 67 slides back and forth on the sliding groove on the curved groove plate 68. Since the hose 610 is flexibly arranged, the sliding shaft 67 drives the fixed pipe 69 to swing left and right when sliding back and forth, and the fixed pipe 69 drives the rotating nozzle 611 to swing left and right in the mounting groove 11 of the front plate 10, so that the rotating nozzle 611 can also swing back and forth when spraying heptafluoropropane gas, thereby expanding the spraying area;The rotating nozzle 611 is provided with two nozzles, and the two nozzles of the rotating nozzle 611 are both located outside the front plate 10. The rotating nozzle 611 is connected with a toothed ring 612, and an arc-shaped rack 613 is installed in the mounting groove 11. The toothed ring 612 meshes with the arc-shaped rack 613. When the rotating nozzle 611 swings left and right, the toothed ring 612 on the rotating nozzle 611 rotates due to the meshing action with the arc-shaped rack 613, so that the toothed ring 612 drives the rotating nozzle 611 to rotate, thereby achieving the effect that the rotating nozzle 611 can also rotate when swinging back and forth left and right, further expanding the spraying range; The setting of the spray assembly 6 enables the rotating spray head 611 to automatically swing back and forth by utilizing the impact force generated by the heptafluoropropane gas when a fire occurs indoors. The reciprocating swing expands the spray range and improves the coverage of the heptafluoropropane gas, thereby avoiding the problem of local fire sources not being covered due to spraying in a fixed direction. The rotating spray head 611 can also rotate while swinging back and forth by the cooperation of the gear ring 612 and the arc-shaped rack 613. The two spray heads on the rotating spray head 611 can expand the longitudinal spatial coverage of the heptafluoropropane gas by rotating, thereby further improving the fire extinguishing efficiency. ;

[0039] For further information, see Figure 8 - Fig.10, the anti-blocking component 7 is used to prevent the pipeline from being blocked. The anti-blocking component 7 includes a slide bar 72, which is slidably installed on the side of the air warehouse 61 close to the air pipe 5. A connecting rod 71 is connected between the slide bar 72 and the ball slider 65. When the ball slider 65 moves back and forth left and right, the slide bar 72 is driven by the connecting rod 71 to slide back and forth on the outer wall of the air warehouse 61. A shift fork 73 is connected to the slide bar 72. Two inner swivel rings 75 are rotatably installed on the inner wall of the air pipe 5. Elbows are respectively provided at the upper and lower ends of the air pipe 5. The two inner swivel rings 75 are both located between the two elbows of the air pipe 5. Four steel sheets 76 are connected between the two inner swivel rings 75. The outer wall of the inner swivel ring 75 located at the top is connected to a rotating rod 74. The rotating rod 74 passes through the air pipe 5. The air pipe 5 is provided with a long The rotating rod 74 is slidably connected with the long groove of the air pipe 5, and the rotating rod 74 is in contact with the shift fork 73. When the shift fork 73 moves back and forth left and right, the rotating rod 74 drives the inner rotating ring 75 located above to reciprocate. A reinforcement ring 77 is connected between the four steel sheets 76. The reinforcement ring 77 can improve the stability of the four steel sheets 76. When the inner rotating ring 75 located above rotates, it drives the four steel sheets 76 and another inner rotating ring 75 to reciprocate. When the four steel sheets 76 reciprocate, they can scrape the inner wall of the air pipe 5. When the air pipe 5 is placed for a long time and the inner wall is scaled, the four steel sheets 76 can scrape off the sediment on the inner wall of the air pipe 5 by scraping, so as to avoid the inner wall of the air pipe 5 from reducing the effective passing area due to a lot of sediment; Two limiting rings 78 are installed, and the ends of the two inner rotating rings 75 away from the steel sheet 76 are respectively connected to four elastic strips 79. The eight elastic strips 79 are divided into two groups, and one group of elastic strips 79 consists of four elastic strips. The two groups of elastic strips 79 are respectively located inside the two elbows of the trachea 5. When the two inner rotating rings 75 rotate, they respectively drive the two groups of elastic strips 79 to reciprocate. The upper group of elastic strips 79 are all active in the gaps between the two limiting rings 78 located at the upper positions and the inner wall of the trachea 5, and the lower group of elastic strips 79 are all active in the gaps between the two limiting rings 78 located at the lower positions and the inner wall of the trachea 5. The two limiting rings 78 in the same elbow limit the four elastic strips 79, so that the elastic strips 79 can maintain contact with the inner rotating ring 75 when it moves. The fit of the inner wall of the elbow and the movement of the four elastic strips 79 in the elbow can prevent the accumulation of sediments at the elbow, and prevent the sediments in the tank body 2 and the air pipe 5 from being deposited at the elbow when following the movement of the heptafluoropropane gas, resulting in local blockage at the elbow of the air pipe 5, thereby affecting the ventilation volume; through the setting of the anti-blocking component 7, the four steel sheets 76 can scrape the inner wall of the air pipe 5 through reciprocating rotation on the inner wall of the air pipe 5, and remove the sediments attached to the inner wall of the air pipe 5, thereby ensuring the ventilation efficiency of the air pipe 5; through the setting of the two groups of elastic strips 79, the two groups of elastic strips 79 can reciprocate in the two elbows of the air pipe 5, thereby preventing the accumulation of a lot of sediments inside the two elbows of the air pipe 5, resulting in blockage in the air pipe 5, thereby affecting the fire extinguishing efficiency.

[0040] Further, see Fig.11 - Fig.13 The cooling assembly 8 is used to prevent the tank body 2 from overheating when a fire occurs. The cooling assembly 8 includes an isolation cover 81, which is installed inside the cabinet 1. Two straps 82 are installed on the isolation cover 81. The tank body 2 is located between the two straps 82 and the inner side of the isolation cover 81. The isolation cover 81 has a certain temperature isolation effect. When a fire occurs indoors, it can reduce the impact of the indoor high temperature on the tank body 2. The tank body 2 is fixed to the inner side of the isolation cover 81 by two straps 82. The straps 82 are provided with buckles. The staff can open the front door 12, open the straps 82 by the buckles, and replace the tank body 2. The interior of the cabinet 1 is supported by a support The frame is equipped with a wind tube 85, and an inner shaft 86 is installed inside the wind tube 85 for rotation. The inner shaft 86 is connected with a fan blade 87, and the fan blade 87 is located inside the wind tube 85. An exhaust hood 83 is installed on the front plate 10, and a section of pipe 84 is connected between the exhaust hood 83 and the wind tube 85. One end of the inner shaft 86 away from the section of pipe 84 is connected to a first gear 88, and the first gear 88 is located outside the wind tube 85. A second gear 89 is connected to the rotating shaft 62, and the second gear 89 is meshed with the first gear 88. When the rotating shaft 62 rotates, the first gear 88 is driven to rotate through the second gear 89. When the first gear 88 rotates, the fan blade 87 is driven to rotate through the inner shaft 86. The fan blade When the cabinet 87 rotates, the air below the rotating nozzle 611 is sucked into the wind tube 85 through the first section of the pipe 84 and the exhaust hood 83. A cooling pipe 811 is serpentinely laid in the isolation hood 81. A second section of the pipe 810 is connected between one end of the cooling pipe 811 and the wind tube 85. An end of the cooling pipe 811 away from the second section of the pipe 810 is connected to an exhaust pipe 812. The end of the exhaust pipe 812 is located outside the cabinet 1. The air in the wind tube 85 is transported to the cooling pipe 811 through the second section of the pipe 810. The air in the cooling pipe 811 is discharged through the exhaust pipe 812. Since the HFC-227ea gas quickly absorbs the temperature of the surrounding air when it is ejected, the air in the exhaust hood 83 is The contact air temperature is lower. After the lower temperature air enters the cooling pipe 811, it can lower the temperature of the isolation cover 81, so that the isolation cover 81 can absorb more heat from the tank body 2 and its vicinity; through the setting of the cooling component 8, the isolation cover 81 can play a certain protective role on the tank body 2, and it is convenient to replace the tank body 2; through the setting of the cooling pipe 811, the cooling pipe 811 uses the cooled air to cool the isolation cover 81, so that the isolation cover 81 absorbs the heat from the tank body 2 and its vicinity, avoiding overheating of the tank body 2 and reducing the risk of explosion of the tank body 2, while also ensuring the stability and fire extinguishing effect of the heptafluoropropane gas.

[0041] With the above structure, the working principle of this case is that the cabinet 1 is installed indoors. When a fire occurs indoors, the fire alarm transmits a signal to the receiver 9, and the receiver 9 controls the solenoid valve 4 to open. After the solenoid valve 4 is opened, the bottle head valve 3 is driven to open, so that the heptafluoropropane gas in the tank 2 enters the air pipe 5 through the bottle head valve 3. The heptafluoropropane gas in the air pipe 5 is sequentially transmitted through the gas warehouse 61, the hose 610, and the fixed pipe 69 to the rotating nozzle 611. The two nozzles on the rotating nozzle 611 spray the heptafluoropropane gas to achieve the effect of extinguishing the fire. When the gas chamber 61 is in operation, the gas pushes the wind wheel 63 to rotate, and the wind wheel 63 drives the rotating shaft 62 to rotate. When the rotating shaft 62 rotates, the cooperation between the reciprocating thread groove 64 and the ball drives the ball slider 65 to slide back and forth left and right. The ball slider 65 drives the lever 66 to move back and forth left and right. When the lever 66 moves back and forth left and right, it drives the sliding shaft 67 through the sliding groove above it, so that the sliding shaft 67 slides back and forth on the sliding groove on the curved groove plate 68. Since the hose 610 is flexibly set, the sliding shaft 67 drives the fixed pipe 69 to swing left and right when it slides back and forth, and the fixed pipe 69 drives the rotating nozzle 611 swings left and right in the installation groove 11 of the front plate 10, so that the rotating nozzle 611 can also swing back and forth when spraying heptafluoropropane gas, thereby expanding the spraying area; when the rotating nozzle 611 swings left and right, the toothed ring 612 on the rotating nozzle 611 rotates due to the meshing action with the arc-shaped rack 613, so that the toothed ring 612 drives the rotating nozzle 611 to rotate, thereby achieving the effect that the rotating nozzle 611 can also rotate when swinging back and forth, further expanding the spraying range; through the setting of the spraying assembly 6, the indoor During a fire, the rotating nozzle 611 can automatically swing back and forth left and right by utilizing the impact force generated by the HFC-227ea gas. The left and right reciprocating swing expands the spraying range, improves the coverage of the HFC-227ea gas, and avoids the problem of local fire sources not being covered due to spraying in a fixed direction. Through the cooperation of the gear ring 612 and the arc-shaped rack 613, the rotating nozzle 611 can also rotate while swinging back and forth left and right. The two nozzles on the rotating nozzle 611 can expand the longitudinal spatial coverage of the HFC-227ea gas by rotating, further improving the fire extinguishing efficiency.

[0042] When the locking cam 75 is in the unlocking state, the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state, so that the locking cam 73 is locked and the locking cam 73 is locked. 78. The two limiting rings 78 in the same elbow limit the four elastic strips 79, so that the elastic strips 79 can maintain the fit with the inner wall of the elbow when following the movement of the inner rotating ring 75. The four elastic strips 79 in the elbow can avoid the accumulation of sediments at the elbow through movement, and avoid the sediments in the tank body 2 and the air pipe 5 from being deposited at the elbow when following the movement of the heptafluoropropane gas, resulting in local blockage at the elbow of the air pipe 5, thereby affecting the ventilation volume; through the setting of the anti-blocking component 7, the four steel sheets 76 can scrape the inner wall of the air pipe 5 through reciprocating rotation on the inner wall of the air pipe 5, and remove the sediments attached to the inner wall of the air pipe 5, thereby ensuring the ventilation efficiency of the air pipe 5; through the setting of the two groups of elastic strips 79, the two groups of elastic strips 79 can reciprocate in the two elbows of the air pipe 5, avoiding the accumulation of a lot of sediments inside the two elbows of the air pipe 5, resulting in blockage in the air pipe 5, thereby affecting the fire extinguishing efficiency.

[0043] The isolation cover 81 has a certain temperature isolation effect. When a fire occurs indoors, it can reduce the impact of the indoor high temperature on the tank body 2. The tank body 2 is fixed to the inner side of the isolation cover 81 by two straps 82. The straps 82 are provided with buckles. The staff can open the front door 12, open the straps 82 through the buckles, and replace the tank body 2; when the shaft 62 rotates, the second gear 89 drives the first gear 88 to rotate, and when the first gear 88 rotates, the inner shaft 86 drives the fan blade 87 to rotate. When the fan blade 87 rotates, the air under the rotating nozzle 611 is sucked into the wind tube 85 through a section of the pipe 84 and the exhaust cover 83. The air in the wind tube 85 is then transported to the cooling pipe 811 through the second section of the pipe 810. The air in the cooling pipe 811 is discharged through the exhaust pipe 812. Since the heptafluoropropane gas will quickly absorb the surrounding air when it is ejected The temperature makes the air temperature that the exhaust hood 83 contacts lower. After the lower temperature air enters the cooling pipe 811, it can reduce the temperature of the isolation cover 81, so that the isolation cover 81 can absorb more heat from the tank body 2 and its vicinity, and avoid the tank body 2 during the fire extinguishing process. The stability of the heptafluoropropane gas inside the tank body 2 is reduced due to the excessively high indoor temperature, thereby increasing the explosion risk of the tank body 2; through the setting of the cooling component 8, the isolation cover 81 can play a certain protective role on the tank body 2 and facilitate the replacement of the tank body 2; through the setting of the cooling pipe 811, the cooling pipe 811 uses the cooled air to cool the isolation cover 81, so that the isolation cover 81 absorbs the heat from the tank body 2 and its vicinity, avoids overheating of the tank body 2, reduces the risk of explosion of the tank body 2, and also ensures the stability of the heptafluoropropane gas and the fire extinguishing effect.
