Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of fire protection engineering, and specifically to a smoke exhaust device for fire protection engineering. Background Art

[0002] Fire smoke is a mixture of harmful gases and particulate matter produced in a fire, and its temperature can usually reach 300℃~800℃, which is mainly due to the heat released during the combustion process and the high temperature of the flame. The hot air in the smoke is lighter than the surrounding air, which will cause the smoke to rise locally, which further exacerbates the high temperature characteristics of the smoke. Therefore, the greater the degree of the fire, the more heat is generated by the combustion, and the faster the smoke rises.

[0003] When the existing smoke exhaust device for fire protection engineering is working, a smoke exhaust fan is usually used to suck the rising smoke into the smoke exhaust duct and then discharge it outdoors. In this process, the high-temperature smoke may cause the smoke exhaust fan to overheat and burn, resulting in the inability to continue the smoke exhaust work. In addition, the large amount of particulate matter contained in the smoke may block the smoke exhaust duct and reduce the smoke exhaust effect.

[0044] Please continue reading Figure 3 The fan rotating part 4 includes a rotating rod 401, a passive fan 402 is arranged at the bottom of the rotating rod 401 through the conical smoking pipe 102, the rotating rod 401 is rotatably connected to the conical smoking pipe 102, and the passive fan 402 is fixedly connected to the rotating rod 401. In this embodiment, by providing the fan rotating part 4, the high-temperature smoke moving upward drives the fan rotating part 4 to rotate, and then drives the movable valve part 6, thereby increasing the water flow inside the nozzle part 10, and facilitating cooling of the high-temperature smoke.

[0045] Please continue reading Figure 4-Figure 6 The two movable valve components 6 include a movable rod 601, a slider 602 is provided on one side of the movable rod 601, both ends of the movable rod 601 are respectively threadedly connected with the tops of the two rotating rods 401, a valve 603 is provided at the bottom of one end of the slider 602 through the tube body 101, the slider 602 is fixedly connected with the movable rod 601, the slider 602 is slidably connected with the tube body 101 through the slide groove 103, the top of the valve 603 is fixedly connected with the slider 602, and the bottom of the valve 603 is slidably connected with the inner side of the valve installation box 1003.

By providing the spring 9, when the high-temperature smoke drives the fan rotating component 4 to rotate, and then drives the movable valve component 6 to move upward, the force is less than the elastic force of the spring 9, and the movable valve component 6 will drop, blocking the nozzle component 10, avoiding the waste of water resources.

[0047] Based on the above structure, when a fire occurs, the motor 201 drives the smoke exhaust fan 203 to rotate, and the high-temperature smoke generated by the indoor combustion is extracted through the conical smoke pipe 102. The water pump 5 extracts a large amount of fire-fighting water from the water storage tank 8, and sends it to the inside of the diverter pipes 702 on both sides through the delivery pipe 701, and then to the inside of the connecting pipe 1001; in this process, the passive fan 402 is driven by the flowing high-temperature smoke, and then drives the rotating rod 401 to rotate, and then drives the spring slider 602 of the top movable rod 601 to move up, and moves along the slide groove 103. When the upward force of the movable rod 601 is greater than the elastic force of the spring 9, the valve 603 is lifted inside the valve installation box 1003, increasing the water flow inside the valve installation box 1003, and the fire water flows into the two nozzle installation pipes 1002; finally, it is sprayed out through multiple nozzles 1004 to cool the high-temperature smoke and filter the particles therein; when the upward force of the movable rod 601 is less than the elastic force of the spring 9, the valve 603 descends inside the valve installation box 1003, reducing the water flow inside the valve installation box 1003 and avoiding waste of water resources.
