Description

Technical Field

[0002] The existing public transportation systems, public buildings, subway platforms and other enclosed places are equipped with fire safety ventilation devices at the air intake vents. When a fire occurs, a large amount of thick smoke will be generated. The fire ventilation devices are installed to absorb the thick smoke to ensure internal and external air circulation and improve the internal air quality.

[0003] A Chinese patent document with publication number CN115468253A provides a fire safety ventilation device, whose structure includes ventilation fan blades, a mounting seat, a main body, a purification device, a clamping ring, and a protective cover. The filter screen is inserted into the processing chamber and plugged into the limit seat. The joint will rest on the frame to stably install the filter screen inside the processing chamber. When exhausting air, the filter screen will directly contact the thick smoke. The filter screen initially blocks impurities in the thick smoke. The blocked thick smoke flows into the interior of the purification tank, and then the thick smoke is purified through the purification tank. The purified thick smoke flows to the exhaust component, and the exhaust component quickly disperses and discharges the thick smoke.

[0004] However, the existing ventilation device is completely driven by external electricity. When a fire occurs, the power supply is easily cut off. After the power supply is cut off, the ventilation device can only rely on air convection to exhaust the smoke and dust outdoors. The smoke and dust exhaust by air convection will be very slow, resulting in poor smoke exhaust effect. The smoke and dust are difficult to be discharged quickly, but it is easy to increase the spread of the fire. Utility Model Content

In this way, the problem that the ventilation device in the prior art is prone to poor exhaust effect due to the external power being cut off when a fire occurs can be solved.

[0027] Preferably, in the embodiment of the present utility model, the emergency power supply 10 is an emergency battery, the controller 11 is a control panel, and the smoke detection component 3 is a smoke sensor.

[0028] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the control unit further includes a relay 13 , and the smoke detection component 3 is electrically connected to the controller 11 via the relay 13 .

[0029] Through the above arrangement, after the smoke detection component 3 senses smoke, the smoke detection component 3 first starts the relay 13, and the relay then starts the controller, and the emergency plan is started through the controller, so that the emergency power supply 10 directly transmits electrical energy to the fluid power mechanism through the controller, so as to utilize the fluid power mechanism to drive the airflow.

[0036] Specifically, Figure 3As shown, in the embodiment of the present utility model, the base 8 is fixedly connected to the outside of the driving motor 6 , and the base 8 is fixedly connected to the air duct housing 1 .

[0037] Specifically, Figure 3 As shown, in the embodiment of the present utility model, the output end of the controller 11 is electrically connected to the driving motor 6 through the connecting wire tube 12.
