The invention discloses a lightweight fire-fighting movable induced draft fan. The lightweight fire-fighting movable induced draft fan comprises a rack assembly and a smoke ventilator. The smoke ventilator comprises a protection shell and a blade driving assembly in the protection shell, and the support assembly comprises a main supporting beam frame. The main supporting beam frame comprises frame-shaped racks on the two sides and multiple connecting beams fixed between the two frame-shaped racks. The protection shell is located between the frame-shaped racks on the two sides, and an adjustingassembly is arranged on each frame-shaped rack. Each adjusting assembly comprises a base plate, a positioning pin and a movable bolt. Each base plate is fixed into an inner hole of the correspondingframe-shaped rack, and pin holes are machined in the base plates. One end of each positioning pin is in running fit with the pin hole of the corresponding base plate, and the other end of each positioning pin is connected with the protection shell. Strip-shaped arc holes are machined in the base plates, and the threaded ends of the movable bolts penetrate through the strip-shaped arc holes and areconnected with the protection shell. According to the lightweight fire-fighting movable induced draft fan, the function that the water mist spraying angle is adjustable is added on the basis of the design concept of being light, simple and easy to operate based on the complete machine, so that the use scene adaptability and adjustability of the complete machine are improved.
Description
technical field [0001] The invention relates to the technical field of fire-fighting and smoke exhaust, in particular to a lightweight fire-fighting mobile smoke exhaust machine. Background technique [0002] The fire smoke exhaust machine is suitable for high-rise buildings, underground buildings, tunnels, subways, industrial and mining enterprises, etc., and can exhaust smoke and reduce radiation.
