Description

Technical Field

[0001] The utility model relates to a fire smoke exhaust device, in particular to a fire smoke exhaust device which is easy to maintain, and belongs to the technical field of fire smoke exhaust. Background Art

[0002] Fire smoke exhaust fans are essential firefighting equipment, primarily used for ventilation or high-temperature smoke exhaust in high-rise buildings, underground structures, tunnels, and other locations. These fans can operate continuously for at least 30 minutes under extreme conditions, such as temperatures of 280°C. This ensures effective smoke exhaust in emergency situations like fires, ensuring safe evacuation and firefighting operations.

[0003] Patent publication number CN220062020U discloses a fire smoke exhaust device that is easy to maintain, including a housing, a support frame fixedly connected to the bottom end of the housing, a motor disposed inside the housing, an impeller fixedly connected to the output shaft of the motor, a limit mechanism disposed inside the housing, the limit mechanism comprising a slide, a slide rail, a support rod, a connecting rod, a disc, and a bump, the outer wall of the bump being plugged with a limit rod, the limit rod passing through and slidably connected to the inner wall of the fixed rod, the limit rod being elastically connected to the inner wall of the fixed rod by a return spring, and the slide being provided on the inner wall of the housing. However, although the device can be pushed out of the housing by releasing the restriction of the fixing bolts, so that the disc and the support rod are away from the housing and exposed to the outer wall of the housing, making it easy for staff to observe and maintain; however, the motor, fan and other structures are separated from the housing, resulting in poor stability of the device as a whole during the smoke exhaust process, and the center is easily offset during the push-out process, causing safety accidents. Therefore, a fire smoke exhaust device that is easy to maintain is proposed. Utility Model Content
