[0005] A fire safety ventilation device comprises a plurality of chassis and a plurality of bellows, wherein the four bottom corners of the chassis are rotatably connected to movable wheels, the top of the chassis is fixedly connected to a battery, a fixing frame is fixedly connected between the front and rear inner walls of the chassis, a ventilator is fixedly connected to the middle of the fixing frame, the ventilator is electrically connected to the battery, connecting pipes are fixedly connected to the middle of the left and right side walls of the chassis, the bellows are located on the left and right sides of the chassis, the bellows are sleeved on the outer wall of the connecting pipe, a fixing device is provided on the outside of the connecting pipe, the fixing device is located on the outer wall of the end of the bellows, the bellows is fixed to the outer wall of the connecting pipe through the fixing device, and the two chassis are connected through the bellows.

[0006] The fixing device includes a circular iron sheet and fixing bolts. The circular iron sheet is sleeved on the end of the corrugated pipe and is located outside the connecting pipe. The fixing bolts penetrate both ends of the circular iron sheet and are fixed to the outer wall of the connecting pipe by the fixing bolts.

[0007] Beneficial effects of the utility model:

[0008] The bottom of the chassis of the utility model is equipped with moving wheels. When facing an emergency, the entire device can be easily moved to any position where ventilation is required, which greatly improves the flexibility and convenience of use; the corrugated pipe is fixed to the connecting pipe by a fixing device, and the installation and removal are very simple, without complicated tools or equipment, which greatly saves the time of installation and removal;

[0009] The flexible nature of the bellows allows it to be bent according to the site environment to adapt to various complex spatial layouts, making the device applicable to more different scenarios;

[0010] When the ventilation path is long, multiple chassis can be connected in series through bellows, and multiple ventilators can work at the same time, which greatly improves the ventilation efficiency and ensures the ventilation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1-4 As shown: a fire safety ventilation device, including a plurality of chassis 1 and a plurality of bellows 8, the bottom four corners of the chassis 1 are rotatably connected with moving wheels 2, the top of the chassis 1 is fixedly connected with a battery 3, a fixing frame 4 is fixedly connected between the front and rear inner walls of the chassis 1, a ventilator 5 is fixedly connected to the middle of the fixing frame 4, the ventilator 5 is electrically connected to the battery 3, the middle of the left and right side walls of the chassis 1 are fixedly connected with connecting pipes 6, the bellows 8 are located on the left and right sides of the chassis 1, the bellows 8 is sleeved on the outer wall of the connecting pipe 6, the outer side of the connecting pipe 6 is provided with a fixing device 7, the fixing device 7 is located on the outer wall of the end of the bellows 8, the bellows 8 is fixed to the outer wall of the connecting pipe 6 through the fixing device 7, and the two chassis 1 are connected through the bellows 8.

[0017] The fixing device 7 includes a circular iron sheet 71 and fixing bolts. The circular iron sheet 71 is sleeved on the end of the corrugated pipe 8. The circular iron sheet 71 is located outside the connecting pipe 6. The fixing bolts pass through both ends of the circular iron sheet 71. The two ends of the circular iron sheet 71 are fixed to the outer wall of the connecting pipe 6 by fixing bolts.

[0018] When the fire safety ventilation device needs to be activated, first ensure that the battery 3 has sufficient power to drive the fan 5, and then move the chassis 1 to the position where ventilation is required through the moving wheel 2; when the chassis 1 reaches the specified position, the circuit between the fan 5 and the battery 3 is connected, and the fan 5 starts to work to generate airflow ventilation; the flexible nature of the bellows 8 allows it to be bent according to the on-site environment to adapt to different spatial layouts. The bellows 8 is fixed to the outer wall of the connecting pipe 6 by the fixing device 7 to ensure the stability of the connection; when the path to be ventilated is long, multiple chassis 1 can be connected in series through the bellows 8, and the fan 5 of each chassis 1 works at the same time, and the airflow is transmitted through the bellows 8, which is more flexible to use and has higher ventilation efficiency than a single fan, and can be bent to adapt to different ventilation paths.
