In particular, oil stains are particularly easy to adhere to the inner wall of the smoke exhaust duct. These oil stains can help combustion in the event of a fire. If a fire occurs inside the duct, these oil stains will increase the speed of the fire spread. Summary of the invention

DETAILED DESCRIPTION

[0018] The present invention is further described below with reference to the accompanying drawings and some embodiments.

[0019] Figure 1-2 A fire smoke exhaust pipe for preventing fires comprises a pipe body 1, a suffocating fire extinguishing device for segmented suffocating fire extinguishing, and a sprinkler device for accelerating fire extinguishing, wherein the suffocating fire extinguishing device and the sprinkler device are both arranged in the pipe body 1;

[0020] The suffocation fire extinguishing device includes a plurality of fire dampers 2 for forming a closed space for suffocation fire extinguishing in a pipeline body 1, a plurality of temperature sensors 3, and a microcontroller 4. The fire dampers 2 are arranged in intervals in the pipeline body 1, and adjacent fire dampers 2 can form a sealed space in pairs when closed. The temperature sensor 3 is arranged in the sealed space, and the microcontroller 4 is arranged outside the pipeline body 1. The temperature sensor 3 is connected to the input end of the microcontroller 4, and the fire damper 2 is connected to the output end of the microcontroller 4. The temperature sensor 3 can detect the temperature change within each sealed space in real time and transmit the temperature information to the microcontroller 4. When a fire occurs, the temperature rises rapidly. After reaching the set temperature, the microcontroller 4 transmits information to the fire damper 2, so that the fire damper 2 doors on both sides of the temperature sensor 3 are closed to form a sealed space, isolate the air, and prevent oxygen from entering the sealed space, thereby achieving the purpose of fire extinguishing. The fire damper 2 can be a square pipeline gas valve or a circular pipeline gas valve commonly used in the prior art. The specific valve type can be determined according to the shape of the actual pipeline;

[0021] The spray device includes a nozzle 5, a water pipe 6, a water tank 7, a booster pump 8 that can change the water pressure to break through the oil film and clear the nozzle 5 when the oil film covers the water outlet of the nozzle 5, a flow meter 9 that can detect the blockage of the nozzle 5, a three-way valve 10, and a water outlet pipe 11. The nozzle 5 is connected to the water outlet end of the three-way valve 10, the water pipe 6 is connected to one of the water inlet ends of the three-way valve 10, the water tank 7 is arranged outside the pipeline body 1, the water pipe 6 is connected to the water tank 7, the booster pump 8 is arranged on the water pipe 6, the flow meter 9 is arranged at the water outlet of the three-way valve 10, and the water outlet pipe 11 is arranged at the bottom of the sealed space. The booster pump 8, the flow meter 9, and the three-way valve 10 are all electrically connected to the microcontroller 4. The nozzle 5 is a water mist nozzle 5. When a fire occurs, the microcontroller 4 synchronously transmits information to the booster pump 8 and the three-way valve 10, so that the three-way valve 10 is opened, the booster pump 8 works, and then sprays water mist from the nozzle 5 to extinguish the fire, and the water after the fire is extinguished is discharged through the outlet pipe 11; the flow meter 9 synchronously monitors the water flow of the three-way valve 10, and transmits the water flow information to the microcontroller 4. When the water flow does not move, the hole on the nozzle 5 is blocked by the discharged oil smoke and covered with a layer of oil film. At this time, the microcontroller 4 transmits information to the booster pump 8, so that the booster pump 8 increases the pressure so that the water pressure can break through the oil film, thereby unblocking the nozzle 5 and enabling the nozzle 5 to work normally. When the flow meter 9 detects that the water flow is normal, the microcontroller 4 transmits it to the booster pump 8, so that the booster pump 8 is adjusted to the normal water pressure to extinguish the fire;

[0022] It also includes a smoke exhaust water device that can drain water and smoke during fire extinguishing to avoid affecting the normal operation of the smoke exhaust pipe, and a cleaning device that can regularly clean the oil stains on the inner wall of the pipe body 1 to prevent fire.

[0023] In this embodiment, the smoke exhaust water device includes a preparatory pipe 12 and a solenoid valve 13. The preparatory pipe 12 is arranged next to the pipe body 1. The other end of the water outlet pipe 11 is connected to the preparatory pipe 12, so that the preparatory pipe 12 is connected to the bottom side of the sealed space, and the solenoid valve 13 is arranged in the water outlet pipe 11; when the three-way valve 10 and the booster pump 8 are opened, the microcontroller 4 transmits to the solenoid valve 13 to open the solenoid valve 13. After opening, water and smoke are discharged from the water outlet pipe 11 together. When the solenoid valve 13 of the sealed space is opened, the adjacent lower solenoid valve 13 is opened, so that the smoke can be discharged normally.

[0024] In this embodiment, the cleaning device includes a detergent box 14, a detergent pipe 15, and a detergent pump 16. The detergent box 14 is arranged outside the pipeline body 1, and the detergent pipe 15 is connected to the detergent box 14 at one end and connected to the other water inlet end of the three-way valve 10 at the other end. The detergent pump 16 is arranged on the detergent pipe 15; under normal conditions, the time can be set so that the inside of the pipeline is cleaned at regular intervals, and the time when no one uses it can usually be selected at midnight. During cleaning, the microcontroller 4 transmits information to the fire damper 2 at the top and the bottom to close it, and then opens all the three-way valves 10 and the detergent pump 16, and then opens the solenoid valve 13 of the water outlet pipe 11 at the bottom, and the detergent spray is sprayed from the nozzle 5 to clean the oil stains inside the pipeline. After the spraying time is set, the detergent pump 16 stops working, and the booster pump 8 works at this time to spray water mist from the nozzle 5 to perform secondary cleaning on the inner wall of the pipeline, and the water and oil stain mixture produced by the cleaning flows into the preparation pipeline 12 through the water outlet pipe 11.
