[0035] In this embodiment, the vertical bracket and the horizontal bracket are welded from square steel. The first vertical bracket 1 and the second vertical bracket 2 are vertical structures and are installed on the ground. The top of the first vertical bracket 1 is in the shape of a letter "I", and the top of the second vertical bracket 2 is in the shape of a letter "O". The horizontal bracket 3 is a rectangular structure and is placed flat on the top of the first vertical bracket 1 and the second vertical bracket 2. Each bracket connection component is designed with bolt holes, and the horizontal bracket 3 is fixedly connected to the first vertical bracket 1 and the second vertical bracket 2 by bolts. The bottoms of the first vertical bracket 1 and the second vertical bracket 2 are designed with fixing holes, which can be fixed to the ground by bolts. The integral bracket is used to support the installation of various smoke prevention system components.

[0036] The vertical air duct 4 is a rectangular cross-section and is installed on the first vertical bracket 1. Its top is flush with the top of the first vertical bracket 1, and the top is open and connected to the transverse air duct 5 through a flange. The transverse air duct 5 includes a first transverse air duct 501, a second transverse air duct 502 and a third transverse air duct 503 connected in sequence. The first transverse air duct 501 is also a rectangular cross-section and is installed on the horizontal bracket 3. The left bottom of the first transverse air duct 501 is open and connected to the vertical air duct 4, and the right side is connected to the left side of the second transverse air duct 502 through a flange. The third transverse air duct 503 is a flexible short air duct. The third transverse air duct 503 is a circular cross-section and is connected to the right side of the second transverse air duct 502 through a flange. The other side of the flexible short air duct is then connected to the blower 6 through a flange.

[0037] The air outlet 8 is a pressurized air supply outlet, which is installed at the lower part of the vertical air duct 4. The air outlet is in a louver shape, and the upper part is provided with a manual air outlet opening device and an automatic air outlet opening device.

[0038] The electric fire damper 11 is installed in the transverse air duct 5 and can be opened and closed by electric control. When the fire damper is opened, the transverse air duct 5 can be ventilated normally, and when the fire damper is closed, the transverse air duct 5 cannot be ventilated. At the same time, the fire damper is built-in with a temperature control module. When the ambient temperature exceeds 70 degrees, the fire damper will automatically close.

[0039] The blower 6 is a pressurized blower, which is controlled by a control module in the control box 10. After being powered on, it can supply pressurized air to the side of the flexible short air duct. A shock-absorbing rubber pad is designed at the bottom of the blower to reduce the vibration between it and the bracket during operation.

[0040] The control box 10 is used for power supply and control of the entire smoke prevention system. Circuit breakers, AC contactors, relays, grounding strips, neutral strips, control terminal strips, etc. are installed inside. The control box door panel is installed with a start / stop button, a manual / automatic conversion switch, indicator lights, etc.; the control box is designed with hanging ears and fixing holes on both sides and is installed on the second vertical bracket 2.

[0042] The mounting plate 7 is a rectangular structural steel plate, fixed below the horizontal bracket 3 and located between the first vertical bracket 1 and the second vertical bracket 2. Two fire detectors 9 are installed below the mounting plate 7. The fire detectors 9 are ceiling-mounted and are a temperature detector and a smoke detector respectively.

[0043] When the present invention is used, it needs to be used in conjunction with a fire engineering control center, which mainly includes a fire system alarm host. The space between the first vertical bracket and the second vertical bracket simulates an indoor room. In the initial state, the two detectors at the top of the room are in an untriggered state, the vertical air duct simulates the passage area outside the room, the pressurized air outlet is initially closed, the horizontal air duct simulates the top area of ​​the room, the electric fire damper is initially open, and the pressurized air supply fan is initially closed.

[0044] When the temperature detector or smoke detector detects the high temperature or thick smoke of a fire, it will send an alarm signal to the fire host of the control center. The fire host will send a start-up electrical signal to the control box to power the pressurized air supply fan, and send the natural wind from the outdoor environment into the first transverse air duct through the flexible third transverse air duct and the second transverse air duct. The natural wind is then sent to the vertical air duct through the first transverse air duct. At the same time, the pressurized air outlet also receives the start-up electrical signal and the air outlet opens. At this time, natural wind will be continuously sent out from the air outlet, simulating the air supply scene of the escape passage outside the room when a fire occurs. If the fire host fails to start the air supply fan after receiving the alarm signal from the detector, the pressurized air outlet can be opened through the manual start device on the pressurized air outlet. At this time, the pressurized air supply fan will also start in conjunction.

[0045] During the air supply process, if the temperature of the incoming natural air exceeds 70 degrees, the temperature control module of the electric fire damper will be activated, forcibly closing the fire damper to ensure the safety of the personnel passage.

[0046] Finally, it should be noted that the above-described embodiments are only specific implementations of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them. The protection scope of the present invention is not limited thereto.
