Industrial big fan with power-off protection mechanism
The utility model is related to industrial big fan technical field more particularly to a kind of industry with power-off protection mechanism are big
In order to improve the comfort of workshop condition, Industrial fan, traditional work are generally both provided in workshop
Industry fan dimension is smaller, is mounted on roof or wall, and the region in order to blow to farther out must assure that setting is enough
More quantity increases cost, and the power of single Industrial fan is very high, and the wind that such Industrial fan is produced by boasting can be very big,
Discomfort is caused to worker, later in order to improve this situation, industrial big fan occurs, the flabellum of industrial big fan is very long, long
Up to several meters, thus only need an industrial big fan can so that large stretch of region generates wind, and need not be very high rotating speed,
So that the wind blown to worker is very soft.
But there is some to influence its a wide range of the shortcomings that promoting the use of for existing industrial big fan, existing industry is big
The operation principle of fan is that driving device (motor) drives fan leaf rotation, and in the case of normal power down, motor is until fan
Leaf stops to impact motor others component there are one the process slowly slowed down, but in the feelings powered off suddenly
Under condition, motor, speed reducer shut down suddenly, and the rotation that fan leaf will continue under the action of inertia, and then compulsory band
Dynamic motor movement, is easily damaged, the service life of motor and other component greatly reduces.
Utility model content
The purpose of this utility model is that in place of avoiding the deficiencies in the prior art, the industry with power-off protection mechanism is provided
Big fan, to effectively solve the shortcomings of the prior art.
To achieve the above object, the technical solution that the utility model is taken is：Industrial strong wind with power-off protection mechanism
Fan, including drive shaft, the rotatable turning set being sleeved on the outside of drive shaft, for driving the driving of the drive shaft turns to fill
Set and be fixed at the strong wind flabellum of turning set bottom；
Elastic component is provided in the turning set, the outside of the drive shaft is circumferentially evenly provided with several place's dampings
Slot, the distance between the inside of damping slot and the drive shaft center of circle continuously enlarge along clockwise direction, and the inside of the elastic component is supported
It leans against in damping slot.
Further, the damping slot is circumferentially evenly provided with everywhere.
Further, the elastic component is circumferentially evenly provided at two.
Further, it is provided with pressure bearing between the drive shaft and turning set.
Further, the driving device includes motor and speed reducer, and the output shaft of speed reducer is fixedly connected with drive shaft.
Further, the elastic component includes threaded rod, jacking block and the spring for connecting the threaded rod, jacking block, institute
It states and the threaded rod is coordinated to be provided with threaded hole on turning set, jacking block acts against in the damping slot.
Further, the threaded hole is arranged along the radial direction of turning set.
Further, it is provided with pressure sensor between the spring and threaded rod, is provided on the outside of threaded rod and pressure
The indicator light of sensor electrical connection.
The above-mentioned technical proposal of the utility model has the advantages that：When unexpected power-off, drive shaft stops
Rotation, due to the elasticity of elastic component and the inertia of strong wind flabellum, turning set drives elastic component to continue to rotate clockwise, at one
In motion process in damping slot, elastic component is gradually compressed, and generates a reaction force to turning set, helps turning set
Stopping as soon as possible, elastic component out can enter another adjacent damping slot from a damping slot, until stopping completely, this
Sample is arranged, and the compulsory drive driving device movement of turning set is to driving device and other portions in the case of avoiding power-off suddenly
Damage, greatly extends driving device and the service life of other component caused by part.

Specific implementation mode
The embodiment of the utility model is described in further detail with reference to the accompanying drawings and examples.Following embodiment
For illustrating the utility model, but cannot be used for limiting the scope of the utility model.
In the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more；Term
The orientation of the instructions such as "upper", "lower", "left", "right", "inner", "outside", " front end ", " rear end ", " head ", " tail portion " or position are closed
System is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, rather than
Indicate or imply that signified device or element must have a particular orientation, with specific azimuth configuration and operation, therefore cannot
It is construed as a limitation of the present invention.In the description of the present invention, it should be noted that unless otherwise specific regulation
And restriction, term " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection,
Or it is integrally connected；It can be mechanical connection, can also be electrical connection；It can be directly connected, intermediary can also be passed through
It is indirectly connected.For the ordinary skill in the art, it can understand above-mentioned term in the present invention with concrete condition
As shown in Figs. 1-3, the industrial big fan with power-off protection mechanism described in the present embodiment, including drive shaft 1, can
It the turning set 2 for being sleeved on the outside of drive shaft 1 of rotation, the driving device for driving drive shaft 1 to rotate and is fixed at
The strong wind flabellum 3 of 2 bottom of turning set, strong wind flabellum 3 are circumferentially evenly provided with multiple；
Elastic component 4 is provided in turning set 2, the outside of drive shaft 1 is circumferentially evenly provided with several place's damping slots 5,
The distance between the inside of damping slot 5 and 1 center of circle of drive shaft continuously enlarge along clockwise direction, and the inside of elastic component 4 is resisted against
In damping slot 5.
The operation principle of the utility model is：As shown in Fig. 2, in a state of use, drive shaft 1 rotates clockwise, elasticity
The inside of part 4 acts against in damping slot 5, and is stuck in the bosom of damping slot 5, thus drive shaft 1 by the transmission of elastic component 4 into
And turning set 2 is driven to rotate, and then strong wind flabellum 3 is driven to rotate, when unexpected power-off, drive shaft 1 stops operating, due to
The elasticity of elastic component 4 and the inertia of strong wind flabellum 3, turning set 2 drive elastic component 4 to continue to rotate clockwise, and are damped at one
