Description

Technical Field

[0001] The utility model relates to the technical field of fire protection engineering, in particular to an automatic smoke exhaust device for fire protection engineering. Background Art

[0002] After a fire occurs, the first process is the generation of a large amount of smoke. If the smoke cannot be discharged smoothly, it will gradually accumulate and settle, which will directly affect safe evacuation. When a fire occurs, the smoke needs to be discharged quickly after it is generated. Therefore, an automatic smoke exhaust device for fire engineering is needed to discharge the smoke.

[0003] When a traditional automatic smoke exhaust device discharges a large amount of smoke, the smoke will cause the indoor pressure to gradually decrease, slowly forming a negative pressure in the room, thereby greatly reducing the smoke exhaust efficiency and causing the smoke to be unable to be discharged; the traditional smoke exhaust device has only a single exhaust port, which is slow in efficiency and delays rescue. Therefore, in response to the above problems, an automatic smoke exhaust device for fire protection engineering is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic smoke exhaust device for fire protection engineering to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

The smoke exhaust device of claim 13, wherein the smoke exhaust fan is connected to the exhaust pipe at the outer side thereof, the temperature detector is fixedly connected to the inner side thereof, the temperature detector is fixedly connected to the temperature probe on the side away from the exhaust pipe, a first connecting pipe is symmetrically arranged on the inner side of the exhaust pipe with the temperature detector as the center, an exhaust port is fixedly connected to the first connecting pipe on the side away from the exhaust pipe, a second filter is fixedly connected to the inside of the exhaust port, an intake pipe is fixedly connected to the bottom end of the exhaust pipe, a smoke detector is fixedly connected to the inner side of the intake pipe, a smoke probe is fixedly connected to the side of the smoke detector away from the intake pipe, an intake fan is connected to the outer side of the intake pipe, a second connecting pipe is connected to the left and right sides of the inner side of the intake pipe, the second connecting pipe is fixedly connected to the air intake on the side away from the intake pipe, a heat insulation layer is fixedly connected to the inside of the exhaust pipe, and the first filter is fixedly connected to the inside of the second connecting pipe.

[0007] Preferably, there are two smoke probes, which are symmetrically arranged on the surface of the smoke detector.

[0008] Preferably, the first connecting pipe and the exhaust port form a group, with a total of four groups, and are symmetrically arranged on the inner side of the exhaust pipe in front and back and left and right directions.

[0009] Preferably, the exhaust pipe and the intake pipe are in a U-shape and have the same size.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by providing the exhaust pipe, exhaust fan, first connecting pipe, exhaust port, air inlet pipe, air inlet and other components, it is realized that the flowing air is supplemented to the room while exhausting the smoke, and the stability of the smoke exhaust system is ensured, thereby solving the problem that when a large amount of smoke is discharged from the traditional automatic smoke exhaust device, the smoke will cause the indoor pressure to gradually decrease, slowly forming a negative pressure in the room, thereby causing a significant reduction in the smoke exhaust efficiency, resulting in the inability to exhaust the smoke;

[0013] 2. In the utility model, by setting four exhaust ports, the smoke generated by the fire can be discharged in multiple directions, which greatly improves the efficiency, thereby solving the problem that the traditional smoke exhaust device has only a single exhaust port, low efficiency and delayed rescue;

[0014] 3. In the utility model, the temperature detector, temperature probe, smoke detector and smoke probe are arranged to monitor the room, detect temperature changes and smoke concentration. If the temperature is too high, the exhaust system will be automatically turned on. If the smoke concentration is too high, the exhaust fan speed will be increased, and the intake fan will be started to replenish air in the room, thus solving the problem that the traditional fire protection engineering automatic smoke exhaust device cannot adjust the exhaust fan power according to the real-time situation; BRIEF DESCRIPTION OF THE DRAWINGS
