Description

Technical Field

[0001] The invention relates to the technical field of fire safety, and in particular to an intelligent alarm device for fire safety. Background Art

[0002] Fire safety refers to the prevention of fires and other emergencies, and the protection of people and property from fires and other disasters, including fire prevention, fire emergency response, fire escape and rescue. Fire safety can be improved through intelligent alarm devices, including smoke detectors, fire alarms, temperature monitors and other devices, which can monitor the fire risk in the environment in real time and issue alarms in time when abnormal conditions are found, so that timely measures can be taken to deal with the fire threat.

[0003] At present, traditional intelligent alarm devices for fire safety generally conduct real-time monitoring of the site based on the feedback from smoke detectors, fire alarms or temperature monitors, and then conduct fire alarms and emergency processing at the fire scene based on the feedback from the sensor equipment. In this process, the on-site monitoring and ringing alarms of the sensor equipment need to be connected to a stable power supply. When a fire occurs, the power supply of the environment will be directly turned off, and the timeliness and power supply effect of the backup battery cannot be guaranteed. Therefore, there will be a certain degree of uncertainty, which increases the risk of fire and is not conducive to the safety of life and property of residents. In addition, after a fire occurs or when the fire sprinkler is damaged, the fire sprinkler needs to be replaced. At present, when replacing the fire sprinkler, it is necessary to first close the corresponding water supply gate, and then empty the other end before replacing it, which is more troublesome.

The water limiting ring 3011 is movably connected to the gyro-shaped valve plate 3013 through the second spring rod 3012 at one end close to the driving rod 1031. The end of the valve plate 3013 close to the driving rod 1031 is fixedly connected to the propulsion rod 3014. The rod body of the propulsion rod 3014 is slidably connected to the inside of the support plate 3015. The support plate 3015 is fixedly connected to the inside of the fire-fighting pipe 301. The pen tip of the propulsion rod 3014 contacts the driving screw 1033. The middle position of the side surface of the conical end of the driving screw 1033 is rotatably connected with a swivel 1034, and one side of the swivel 1034 is fixedly connected to the linkage rod 1035.

[0044] During operation, if the fire sprinkler is damaged, the bolt at the lower end of the driving rod 1031 can be rotated to drive the driving rod 1031 to rotate, and the driving rod 1031 will drive the driving screw 1033 to rotate, and the driving screw 1033 will rotate downward from the inside of the screw seat 302, and in the process of rotating out, push the propulsion rod 3014 to both sides, and the propulsion rod 3014 will slide along the support piece 3015 and compress the second spring rod 3012 supporting the valve plate 3013 until the valve plate 3013 is tightly attached to the water outlet at the center of the water limiting ring 3011, so as to achieve the blocking of the fire pipe 301, and in the process of the valve plate 3013 moving and blocking, as the driving screw 1033 moves downward, it will simultaneously drive the linkage rod 1035 to move downward, and the linkage rod 1035 will press the gate downward Plate 2023 is pressed to make it slide down along the water control pipe 2022, and the first spring rod 2024 is compressed during the sliding process until the water outlet on the surface of the gate plate 2023 is directly opposite to the water outlet on the upper end of the water control pipe 2022. At this time, the water intercepted between the valve plates 3013 will quickly flow into the water control pipe 2022 and be discharged from the through hole at the bottom of the alarm bell 202. Then the alarm structure 2 can be disassembled from the inside of the wall to the oblique lower side, and the alarm structure 2 can be separated from the detection structure 1. Then the detection structure 1 is rotated to separate the detection structure 1 from the fire protection pipeline 301. Then the alarm structure 2 and the detection structure 1 can be inspected, maintained or replaced. When replacing and reinstalling, the detection structure 1 must be installed first, and then the alarm structure 2 is installed. Then the alarm structure 2 is fixed, and the drive screw 1033 is reset before it can be used again.

[0045] To sum up, through the arrangement of the drive rod 1031, the drive screw 1033, the water control pipe 2022, the gate plate 2023 and the pipe sealing structure 3, when the equipment is damaged, part of the fire-fighting pipeline 301 can be manually and quickly blocked, and the water inside the blocked area can be led out during the blocking process. In this way, during the maintenance of the fire safety intelligent alarm device, there is no need to close the sluice gate and drain the water at the front end, which can greatly reduce the trouble of maintenance and improve the convenience of maintenance operations.

[0046] Working principle: During operation, when a fire occurs, if the fire source is on one side of the alarm structure 2, the high-temperature gas will directly transfer the temperature to the surface of the external introducer 1022, and the mercury 1021 inside the external introducer 1022 will expand rapidly after being heated and push the valve body 1023 upward, and at the same time compress the compression spring 1024. At this time, the expansion speed of the mercury column 2041 is lower than the mercury 1021 inside the external introducer 1022. As the valve body 1023 moves upward, it will drive the tooth plate 2011 to move, and the tooth plate 2011 will drive the gear set 2012 to rotate through the side teeth. The large gear in the gear set 2012 will drive the small gear to rotate rapidly, and at the same time, it will drive the pay-off wheel 20121 to rotate, and the pay-off The wheel 20121 will lower the wound pull rope, and the length of the rope lowered is greater than the pay-off length generated by the mercury column 2041, and then the end of the warning light 203 connected to the pay-off wheel 20121 will rotate and offset with the water guide plate 2032 as the center, and during the rotation, the liquid inside the spindle cavity liquid tube 2031 will act on the button switch surface of the warning light 203 close to the alarm structure 2, so that the warning light 203 is powered on and illuminates to warn the direction of the fire source, thereby guiding the people in the room to escape, and the small gear will coaxially drive the drive plate 2013 to rotate, and the rotating drive plate 2013 will pull the striking rod 2014 up and down in a rotating manner, so that it can slide back and forth up and down along the slide rail 2021, and when it slides to the bottom to hit On the surface of the alarm 202, the alarm 202 produces a loud sound to ring the room of the fire. When the upper valve ring of the valve body 1023 moves out of the heat-resistant body 102 and enters the fire-fighting pipe 301, the alarm 202 stops ringing. In the process of the valve body 1023 moving up into the fire-fighting pipe 301, the valve body 1023 simultaneously pushes up the driving screw 1033 through the connecting kit 1025. In the process of the driving screw 1033 moving up along the screw seat 302, the pushing rods 3014 of the sealing pipe structure 3 on both sides thereof gradually approach it under the action of the second spring rod 3012, and the blocking of the water limiting ring 3011 by the valve plate 3013 will gradually decrease, and the opening caliber will gradually increase, and the water flow rate passing through will increase. When the annular hole at the upper end of the heat-resisting body 102 is connected with the interior of the fire-fighting pipe 301, the water in the fire-fighting pipe 301 will enter the gap between the heat-resisting body 102 and the valve body 1023, and enter the interior of the transfer water chamber 1012 through the water hole 1013 on the surface of the heat-resisting body 102, and then flow out from the water hole 1013 at the bottom of the transfer water chamber 1012, and fall on the surface of the water guide plate 2032 that deflects synchronously with the spindle chamber liquid pipe 2031, and then the water will flow mainly in the direction of the fire source under the guidance of the water guide plate 2032, and fall on the surface of the sprinkler plate 1011, and then sprinkle in the direction of the fire source, so as to realize the water spraying fire extinguishing of the fire house, and when the fire stops, the mercury 1021 will be compressed and reset by the compression spring 1024;If the fire source is on the side away from the alarm structure 2, the mercury column 2041 will be heated and expanded first, and the expanded mercury column 2041 will push down the moving body 2042, and the moving body 2042 will compress the pay-off spring 2043 during the downward movement, and the lower end of the lower body 2042 will be connected to the pull rope, and the warning light 203 connected to the pull rope will rotate and deviate around the water guide plate 2032. At this time, the liquid inside the spindle cavity liquid tube 2031 moves to the side away from the alarm structure 2, and the warning light 203 is powered on to emit light to warn the direction of the fire source, thereby guiding the indoor personnel to escape. In this process, the expansion speed of the mercury 1021 inside the external introducer 1022 is lower than that of the mercury column 2041, and the pay-off length is less than the pay-off length generated by the mercury column 2041, and the direction of the water spray is still mainly the direction of the fire source.

[0047] If the fire sprinkler is damaged, the bolt at the lower end of the driving rod 1031 can be rotated to drive the driving rod 1031 to rotate, and the driving rod 1031 will drive the driving screw 1033 to rotate, and the driving screw 1033 will rotate downward from the inside of the screw seat 302, and in the process of rotating out, push the push rod 3014 to both sides, and the push rod 3014 will slide along the support piece 3015 and compress the second spring rod 3012 supporting the valve plate 3013 until the valve plate 3013 is tightly attached to the water outlet at the center of the water limiting ring 3011, so as to achieve the blocking of the fire pipe 301, and in the process of the valve plate 3013 moving and blocking, as the driving screw 1033 moves downward, it will simultaneously drive the linkage rod 1035 to move downward, and the linkage rod 1035 will press down the gate plate 2 023, so that it slides down along the water control pipe 2022, and compresses the first spring rod 2024 during the sliding process until the water outlet on the surface of the gate plate 2023 is opposite to the water outlet on the upper end of the water control pipe 2022. At this time, the water intercepted between the valve plates 3013 will quickly flow into the water control pipe 2022 and be discharged from the through hole at the bottom of the alarm bell 202. Then, the alarm structure 2 can be disassembled from the inside of the wall to the oblique lower side, and the alarm structure 2 can be separated from the detection structure 1. Then, the detection structure 1 can be rotated to separate the detection structure 1 from the fire-fighting pipeline 301. Then, the alarm structure 2 and the detection structure 1 can be inspected, maintained or replaced. When replacing and reinstalling, the detection structure 1 must be installed first, and then the alarm structure 2 is installed. Then, the alarm structure 2 is fixed, and the drive screw 1033 is reset before it can be used again.

[0048] It should be noted that the force exerted on the pull rope during the expansion of mercury column 2041 is the same as that of mercury 1021.
