Description
Technical Field
The utility model relates to a fan technical field, concretely relates to axial-flow type smoke exhaust fan.
Background
With the development of the construction industry, the fire prevention problem of buildings becomes more and more important. Modern buildings built in recent years are generally provided with a fire-fighting smoke exhaust system, and the system mainly comprises a sensing device, a control device, a smoke exhaust air duct, a smoke exhaust fan and the like. The smoke exhaust fan is a core component of a fire-fighting smoke exhaust system, and the development of the high-performance fire-fighting smoke exhaust fan can generate good economic and social benefits. The vibration of the fan is a common phenomenon in operation, and cannot cause great influence as long as the vibration is within a vibration control range. However, after the vibration of the fan exceeds the standard, the fan causes the faults of damage of a bearing seat or a motor bearing, loosening of a motor foundation bolt, damage of a fan shell, blades and a wind channel, burning of the motor, heating and the like, so that the working performance of the fan is reduced, and even the fan cannot work at all. Accidents may be caused by vibration seriously, and the personal health and the working environment are harmed.
SUMMERY OF THE UTILITY MODEL
The utility model provides an axial-flow type smoke exhaust fan to solve the problem that the fan vibration that prior art exists influences fan normal operating greatly.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an axial-flow type smoke exhaust fan, by the casing, the shock attenuation seat, a plurality of blades, the motor barrel, motor and wheel hub constitute, the motor is fixed inside the motor barrel, the motor barrel passes through the link and links to each other with the casing, the bolt fastening is passed through at the shock attenuation seat top in the casing bottom, the shock attenuation seat is by the shock attenuation upper cover, vibration damping bottom plate and a plurality of limiting plate are constituteed, the bottom and the vibration damping bottom plate top symmetry of shock attenuation upper cover set up a plurality of magnets, the magnet of shock attenuation upper cover is the same magnetic pole with vibration damping bottom plate's magnet opposite face, the limiting plate is fixed and can be spacing to preventing to deviate from to the shock attenuation upper cover on vibration damping bottom plate, the output shaft of motor links to each other with wheel hub.
The utility model discloses an operating principle is the blade coaxial coupling of installation on motor and the wheel hub, the blade is inhaled gaseous medium through the arc windward side under the motor drives and is entered, wind gets into the inside tailwheel department discharge of then motor barrel rear end of motor barrel, the operation in-process, the magnet of shock attenuation upper cover is the same magnetic pole with damping bottom plate's magnet opposite face, the shock attenuation upper cover can be unsettled at the damping bottom plate top like this, the vibration that the fan produced can conduct to the shock attenuation upper cover, the shock attenuation upper cover can downstream under the effect of vibrations, thereby the repulsive force of vibrational force and magnet homopolar offsets each other and slows down the fan vibration.
The utility model discloses an axial-flow type wind-guiding structure utilizes the arc windward side of blade to combine the tailwheel of motor rear end, can discharge fume the wind-guiding steadily, and the vibration power of fan is offset to the repulsion force that the magnet homopolar of shock mount bottom the fan utilization, has effectively ensured fan operating stability, has design benefit, durable and the good advantage of shock attenuation effect.
