Description

Technical Field

[0001] This utility model belongs to the field of smoke exhaust duct technology, specifically a smart fire-fighting smoke exhaust duct. Background Technology

[0002] Fire protection engineering is a comprehensive discipline involving the intersection, penetration, and integration of many other disciplines. Smoke control and exhaust systems are an important component of fire protection systems. Fire exhaust ducts are smoke extraction systems used inside buildings, playing a crucial role in fire emergencies. They are used to remove smoke, heat, and harmful gases during a fire, ensuring safe passage for people to escape and for firefighters to conduct firefighting and rescue operations. Fire exhaust ducts are usually made of materials such as metal or high-temperature resistant plastics. When existing smoke exhaust ducts are in use, they produce a large amount of smoke during a fire. The smoke has a high temperature and contains many toxic and harmful particles. If directly discharged into the atmosphere, it will cause air pollution and harm the environment and human health. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a smart fire-fighting smoke exhaust duct, which solves the problem that when a fire occurs, a large amount of smoke is generated. The smoke has a high temperature and contains a lot of toxic and harmful particles. If it is directly discharged into the atmosphere, it will cause air pollution and harm the environment and human health.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a smart fire-fighting smoke exhaust duct, including an exhaust pipe, a through groove is provided at the bottom of the exhaust pipe, a water storage tank is fixedly connected to the bottom of the exhaust pipe at the through groove, the water storage tank is connected to the through groove, a sliding frame is slidably connected through the top of the inner wall of the water storage tank, a filter screen is provided on the inner wall of the sliding frame, a water pump is fixedly connected to the bottom of the inner wall of the water storage tank, a water pump is installed at one end of the water pump passing through the water storage tank, the water pump is fixedly connected to the water storage tank, a guide pipe is provided at the top of the water pump, a spray strip is installed at one end of the guide pipe passing through the top of the exhaust pipe, the spray strip is fixedly connected to the top of the inner wall of the exhaust pipe, and the position of the spray strip corresponds to that of the through groove.

[0005] As a further embodiment of this utility model: a handle is fixedly connected to one side of the sliding frame, and two locking seats are installed on the side of the sliding frame near the handle.

[0006] As a further embodiment of this utility model: two locking rods are rotatably connected to the top of one side of the water storage tank via a rotating shaft, and the locking rods correspond to the locking seats.

[0007] As a further embodiment of this utility model: an air inlet pipe is connected to one side of the air outlet pipe by bolt thread, and a motor frame is fixedly connected inside the air inlet pipe.

[0008] As a further embodiment of this utility model: an output motor is fixedly connected to the inner wall of the motor frame, and the output motor is equipped with fan blades through an output shaft.

[0009] As a further embodiment of this utility model: a smoke sensor is fixedly connected to the bottom of the air inlet pipe, and a smoke alarm is fixedly installed on the bottom of the air inlet pipe on one side of the smoke sensor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This intelligent fire-fighting smoke exhaust duct, through the installation of a filter screen, water suction pipe, water pump, and guide pipe, uses an output motor to drive the fan blades to rotate, causing the fan blades to carry smoke into the exhaust duct. The water pump guides water from the storage tank to the guide pipe through the water suction pipe. As the water continues to flow upward, it flows through the guide pipe into the spray bar and is sprayed out, allowing the water flow to come into contact with the smoke. While cooling and dissipating heat from the smoke, the water also traps particles in the smoke, which fall onto the filter screen for filtration. The particles are then left on the filter screen, and the water falls back into the storage tank for recycling, improving the safety of smoke exhaust from the duct.

[0012] 2. This intelligent fire-fighting smoke exhaust duct is equipped with a handle, sliding bracket, snap-fit ​​seat, and snap-fit ​​rod. Rotating the snap-fit ​​rod moves it away from the top of the snap-fit ​​seat, thus removing the snap-fit ​​rod's restriction on the sliding bracket. Pulling the handle causes the sliding bracket to detach from the water storage tank, thereby causing the filter screen inside the sliding bracket to detach from the water storage tank. This facilitates the replacement or cleaning of the filter screen and prevents it from becoming clogged after long-term use. Attached Figure Description

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a smart fire-fighting smoke exhaust pipe, including an air outlet pipe 1, an air inlet pipe 13 connected to one side of the air outlet pipe 1 by bolt thread, and a motor frame 14 fixedly connected inside the air inlet pipe 13. By setting the motor frame 14, the motor frame 14 can support the output motor 15, so that the output motor 15 can be fixed inside the air outlet pipe 1.

[0019] An output motor 15 is fixedly connected to the inner wall of the motor frame 14. The output motor 15 is equipped with a fan blade 16 through the output shaft. By setting the fan blade 16, the output motor 15 drives the fan blade 16 to rotate through the output shaft, so that the fan blade 16 can drive the smoke to flow towards the air outlet duct 1, which facilitates the treatment and discharge of the smoke inside the air outlet duct 1.

[0020] A smoke sensor 17 is fixedly connected to the bottom of the air inlet duct 13. A smoke alarm 18 is fixedly installed on the bottom of the air inlet duct 13 on one side of the smoke sensor 17. When particulate impurities in the smoke enter the smoke sensor 17, the smoke alarm 18 is triggered to sound an alarm.

[0021] A through groove 2 is provided at the bottom of the air outlet duct 1. A water storage tank 3 is fixedly connected to the bottom of the air outlet duct 1 in the through groove 2. The water storage tank 3 is connected to the through groove 2. A sliding frame 4 is slidably connected through the top of the inner wall of the water storage tank 3. By setting the sliding frame 4, which is set on the inner wall of the water storage tank 3, the filter screen 5 in the sliding frame 4 can filter the water mixed with particulate impurities, so that the water can fall back into the water storage tank 3 for recycling, reducing water consumption.

[0022] A handle 10 is fixedly connected to one side of the sliding frame 4. Two locking seats 11 are installed on the side of the sliding frame 4 near the handle 10. Two locking rods 12 are rotatably connected to the top of the side of the water tank 3 via a rotating shaft. The locking rods 12 are positioned corresponding to the locking seats 11. By setting the locking rods 12 and rotating the locking rods 12, the locking rods 12 are locked onto the top of the locking seats 11, so that the locking rods 12 can limit and fix the sliding frame 4 through the locking seats 11.

[0023] A filter screen 5 is installed on the inner wall of the sliding frame 4. A water pump 6 is fixedly connected to the bottom of the inner wall of the water tank 3. One end of the water pump 6 passes through the water tank 3 and a water pump 7 is installed thereon. The water pump 7 is fixedly connected to the water tank 3. A guide pipe 8 is installed on the top of the water pump 7. One end of the guide pipe 8 passes through the top of the air outlet pipe 1 and a spray strip 9 is installed thereon. The spray strip 9 is fixedly connected to the top of the air outlet pipe 1 and the position of the spray strip 9 corresponds to that of the through groove 2. By setting the spray strip 9, the water flows through the guide pipe 8 and enters the spray strip 9, and then sprays out into the air outlet pipe 1 through the spray strip 9, so that the water can cool and adsorb the smoke inside the air outlet pipe 1.

[0024] The working principle of this utility model is as follows:

[0025] In use, smoke comes into contact with the smoke sensor 17. When the smoke sensor 17 detects smoke, it activates the smoke alarm 18 to sound an alarm. At the same time, the output motor 15 is started. The output motor 15 drives the fan blades 16 to rotate through the output shaft, causing the fan blades 16 to carry the smoke from the air inlet duct 13 to the air outlet duct 1. Simultaneously, the water pump 7 drives the water in the water storage tank 3 to flow into the water pumping pipe 6, allowing the water to be drawn into the guide pipe 8 and then sprayed out through the guide pipe 8 into the spray bar 9. Thus, the water comes into contact with the smoke entering the air outlet duct 1, allowing the water to cool the smoke. Meanwhile, water carrying particulate impurities from the smoke flows downwards until it falls on top of the filter screen 5. It is then filtered by the filter screen 5, leaving the particulate impurities on top of the filter screen 5. The water then falls back into the water storage tank 3 for recycling. When it is necessary to remove the filter screen 5 for cleaning, rotate the locking rod 12 to make the locking rod 12 rotate away from the top of the locking seat 11, thereby releasing the limit on the sliding frame 4. Pull the handle 10 to make the handle 10 drive the sliding frame 4 to slide out of the water storage tank 3, so that the sliding frame 4 moves the filter screen 5 out of the water storage tank 3, making it easier to clean the filter screen 5.
