Description

Technical Field

[0001] The utility model relates to the technical field of fire protection Internet of Things, and specifically to a fire protection smoke prevention device based on the fire protection Internet of Things. Background Art

[0002] The Fire Internet of Things is a fire safety management system based on the Internet of Things technology. It uses various sensors, controllers, communication equipment and other technical means to achieve real-time monitoring, control and management of fire-fighting facilities, fire-fighting equipment, fire-fighting water sources inside and outside the building, thereby improving the efficiency and accuracy of fire safety management.

[0003] Fire smoke prevention device is an important part of the fire Internet of Things. It is mainly composed of smoke detectors, smoke sensors, sound and light alarms, controllers and other equipment. It can monitor the smoke, flames and other conditions inside the building in real time. Once an abnormal situation is detected, it will immediately send out an sound and light alarm signal to remind people to take timely measures to avoid fire accidents.

[0004] The working principle of the fire-fighting and smoke-proof device is that the smoke detector and smoke sensor sense the smoke and flames in the surrounding environment and transmit the signal to the controller. The controller determines whether it is necessary to issue an alarm signal based on the received signal and alerts people through the sound and light alarm. At the same time, the controller can also send the alarm signal to the fire department so that rescue measures can be taken in time.

[0005] It can monitor the smoke and flame conditions inside the building in real time, detect fire hazards in time and avoid fire accidents. At the same time, it can also remotely control fire-fighting facilities through controllers to improve the efficiency and accuracy of fire safety management. Therefore, in modern buildings, fire smoke prevention devices have become an indispensable fire safety equipment.

[0006] The existing fire smoke prevention devices based on the fire Internet of Things are generally aimed at the problem that the door gap is not sealed tightly enough, causing smoke to enter the room, posing a threat to human life safety. They do not have the function of purifying, filtering, eliminating smoke and reducing dust in the affected room, so that the fire smoke prevention can not be effectively improved. For example, the authorized Chinese patent CN217503909U discloses a fire smoke prevention device based on the fire Internet of Things, which can achieve the purpose of thoroughly purifying smoke and dust through the coordinated use of structures such as exhaust fans, fan drive motors, motor protection covers, controllers, network transmitters, gathering covers, air supply cabins, airflow ducts, water tanks, partitions, filters and purification cabins, so that the filtered and purified smoke can be discharged, thereby achieving the effect of eliminating smoke and reducing dust, improving fire smoke prevention and slowing down smoke spread.

[0007] However, when the fire-fighting smoke prevention device based on the fire-fighting Internet of Things in the above-cited document is in use, in the process of smoke being discharged into the water tank through the suction pipe, due to the different physical properties of water and smoke, the smoke cannot be completely mixed with water, but forms a mixture of a certain proportion. First, the density of water is much higher than that of air. Therefore, in the water tank, water will sink to the bottom, while smoke will float on the surface of the water. Secondly, the intermolecular interaction forces of water and smoke are also different, which makes them unable to completely dissolve in each other. Therefore, in the water tank, smoke and water will form a mixture of a certain proportion, in which part of the smoke will be dispersed into the water with the movement of the water, and the other part will float on the water surface and eventually be discharged into the air, so that the smoke is not completely filtered, which will still threaten the lives of personnel, resulting in the need to improve the use effect of the existing fire-fighting smoke prevention device.

[0034] In this embodiment, the fully dissolving stirring mechanism 600 is a structure for stirring and fusing water, surfactant and smoke.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the fully dissolving stirring mechanism 600 includes a waterproof box 601 fixedly mounted on the inner wall of the filtered water tank 1 and a driving component installed in the waterproof box 601, one side of the driving component is connected to a gear transmission component and a stirring component connected to the gear transmission component, and the outer side of the stirring component is connected to a scraping component that fits the filtered water tank 1;

[0038] It can be understood that one side of the No. 1 bearing support 6023 is fixedly mounted on the inner wall of the waterproof box 601, and the outer side of the No. 1 rotating rod 6022 is rotatably connected to the inner side of the No. 1 bearing support 6023 through a bearing, in order to more stably support the rotation of the No. 1 rotating rod 6022.

[0039] In addition, the gear transmission assembly includes a driving bevel gear 6031 and a driven bevel gear 6032; one side of the servo motor 6021 is fixedly connected to an end of the first rotating rod 6022 away from the servo motor 6021;

[0040] The servo motor 6021 drives the first rotating rod 6022 to rotate, so as to drive the driven bevel gear 6032 meshed with the driving bevel gear 6031 to rotate, so as to stably drive the stirring assembly to rotate.

[0041] In this embodiment, the stirring assembly includes a No. 2 rotating rod 6041, a No. 2 bearing support 6042 and a stirring rod 6043; one end of the No. 2 rotating rod 6041 penetrates the waterproof box 601 and is fixedly connected to one side of the driven bevel gear 6032, and the other end sequentially penetrates the scraping assembly and is rotatably connected to the inner side of the No. 2 bearing support 6042 through a bearing, and one side of the stirring rod 6043 is fixedly connected to the outer side of the No. 2 rotating rod 6041, and the number of stirring rods 6043 is multiple and evenly distributed, so as to fully blend the surfactant with water and smoke, promote the mutual dissolution of water and smoke, thereby reducing the concentration of smoke;

[0046] The working principle of the above embodiment is:

[0047] When a fire occurs, a large amount of smoke is sucked in by the exhaust fan 2, and the sucked smoke enters the smoke hood 4. The smoke hood 4 adopts a circular groove structure. The circular groove can gather the smoke and generate a vortex airflow as the exhaust fan 2 sucks in, so that the inhaled smoke can flow around in the smoke hood 4 and enter the filtered water tank 1 through the smoke pipe 5. The smoke enters the area where the surfactant and water are mixed in the filtered water tank 1. Then, the servo motor 6021 is started, and the first rotating rod 6022 is driven to rotate stably under the rotation support of the bearing, so as to drive the driven bevel gear 6032 meshed with the driving bevel gear 6031 to rotate. Under the rotation support of the bearing, the second rotating rod 6041 rotates with the driven bevel gear 6032, and drives the second rotating rod 6041 to rotate. The stirring rod 6043 fixed on the outside of the rotating rod 6041 rotates, and the rotating connecting block 6051 rotates accordingly, and drives the scraper 6053 fixed on the connecting rod 6052 to continuously scrape the inner wall of the filtered water tank 1, so as to promote the mutual dissolution of water and smoke, thereby reducing the concentration of smoke. The surfactant adsorbs on the surface of the smoke particles to reduce the attraction between the particles, so that the smoke particles are more easily surrounded and dissolved by water molecules. Water and surfactants are used to filter the smoke, and many particles and impurities in the smoke are filtered out. The filtered gas emerges from the water and is filtered through multiple filter screens. Each filter screen uses an asbestos net or a fiber net, which can adsorb and filter the impurities in the gas again, that is, it can adsorb and filter the harmful substances in the gas, thereby achieving the purpose of completely purifying the smoke.

[0048] Compared with the prior art: the fire-fighting smoke prevention device based on the fire-fighting Internet of Things, through the mutual coordination of the exhaust fan 2, the controller 3, the smoke hood 4, the smoke pipe 5 and the fully dissolving and stirring mechanism 600 on the filtering water tank 1, can provide a function of stirring and fusing water, surfactants and smoke. The surfactants are adsorbed on the surface of the smoke particles to reduce the attraction between the particles, so that the smoke particles are more easily surrounded and dissolved by water molecules, thereby reducing the concentration of the smoke and making the smoke more dispersed in the surfactant, thereby effectively improving the use effect of the existing fire-fighting smoke prevention devices and solving the problem of poor use effect of the existing fire-fighting smoke prevention devices.
