Abstract
The utility model discloses a kind of industrial exhaust fan protection type shutters, including forms, blade, shaft, the forms are mounted on exhaust fan, the forms are equipped with the window of installation blade, the blade is connected to by shaft on forms, and the first half that the shaft is mounted on blade allows blade to keep hang by its own gravity.A kind of industrial exhaust fan protection type shutter of the utility model, is closed automatically when so that it is not worked using the dead weight of shutter, and due to the effect of wind turbine when work, shutter blows certain angle open by outlet air, and angle is with air output adjust automatically.When shutdown when not used, due to gravity, shutter sagging closure automatically plays the role of protecting equipment.As a result of convex bending and sinking bending, ensure good fit between each blade and blade and windowsill, makes it have good appearance and sealing effect.The utility model is simple in structure, and manufacture is easy for installation.
Description
Technical field
The utility model is related to a kind of air draft fan leaf, more particularly to a kind of industrial exhaust fan protection type shutter.
Background technology
Industrial exhaust fan conventional blind adjustment is mostly that craft or motor drive and adjust the angle or operate not side
Just or cost is excessively high, is not suitable for the operating mode of unattended industrial exhaust fan.And the shutter of traditional industry exhaust fan is also
It is easy, into dirt into rain, to be easy to cause the damage of fan.
In view of the above problems, the utility model provides a kind of industrial exhaust fan protection type shutter, using shutter from
It is closed automatically when so that it is not worked again, since the effect of wind turbine, shutter blow certain angle open by outlet air when work,
And angle is with air output adjust automatically.
Utility model content
The main purpose of the utility model is to provide a kind of industrial exhaust fan protection type shutters, can effectively solve to carry on the back
Technical problem in scape technology.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of industrial exhaust fan protection type shutter described in the utility model, including forms, blade, shaft, the window
Body is mounted on exhaust fan, and the forms are equipped with the window of installation blade, and the blade is connected to by shaft on forms,
The first half that the shaft is mounted on blade allows blade to keep hang by its own gravity.
Further, a kind of industrial exhaust fan protection type shutter described in the utility model, the blade are flat up and down
Between-line spacing arranges, and can be pressed on the blade of lower part after the upper sheet blade is sagging.
Further, a kind of industrial exhaust fan protection type shutter described in the utility model, subordinate on the blade
Recessed, the blade lower part is convex, and neighbouring blade can be with lapping together；It is provided with folding at left and right sides of the window
Side, flanging install the circular hole of shaft equipped with through.
Further, a kind of industrial exhaust fan protection type shutter described in the utility model, the window lower part is set
It is equipped with sinking bending, the bending makes blade be kept in one plane with forms in a piece of blade closed state under most.
Further, a kind of industrial exhaust fan protection type shutter described in the utility model, the window top is set
It is equipped with convex bending, the convex height of the convex bending is more than a piece of blade of topmost, and the convex bending is leant out
Part is enough to block the top edge of topmost blade.
Further, a kind of industrial exhaust fan protection type shutter described in the utility model, the forms are provided with
Mounting hole.
Compared with prior art, the utility model has the advantages that：The folding angle of shutter is according to exhaust fan
Wind speed adaptively adjusted；When shutdown when not used, due to gravity, shutter sagging closure automatically plays protection and sets
Standby effect.Simultaneously as using convex bending and sinking bending, ensure good between each blade and blade and windowsill
Fitting, makes it have good appearance and sealing effect.The utility model is simple in structure, and manufacture is easy for installation.
Description of the drawings
Fig. 1 is a kind of dimensional structure diagram of industrial exhaust fan protection type shutter of the utility model；
Fig. 2 is a kind of side view of industrial exhaust fan protection type shutter of the utility model.
In figure：1, forms；2, blade；3, shaft；4, window；5, flanging；6, circular hole；7, sinking bending；8, convex bending；
9, mounting hole.
Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-2, a kind of industrial exhaust fan protection type shutter described in the utility model, including forms 1, blade
2, shaft 3, the forms 1 are mounted on exhaust fan, and the forms 1 are equipped with the window 4 of installation blade 2, and the blade 2 is logical
It crosses shaft 3 to be connected on forms 1, the first half that the shaft 3 is mounted on blade 2 allows blade 2 to pass through its own gravity
Keep hang.
Further, about 2 parallel interval of blade arrangement, can be pressed in after the upper sheet blade 2 is sagging
On the blade 2 of lower part.
Further, 2 top of blade is recessed, and 2 lower part of blade is convex, and neighbouring blade 2 can be with
Lapping is together；4 left and right sides of window is provided with flanging 5, and flanging 5 installs the circle of shaft 3 equipped with through
Hole 6.
Further, 4 lower part of window is provided with sinking bending 7, a piece of blade 2 under most of the sinking bending 7
Blade 2 is made to be kept in one plane with forms 1 when closed state.
Further, 4 top of window is provided with convex bending 8, and the convex height of the convex bending 8 is more than
The a piece of blade 2 of topmost, the convex bending 8 lean out part and are enough to block the top edge of topmost blade 2.
Further, the forms 1 are provided with mounting hole 9.
It should be noted that the utility model is a kind of industrial exhaust fan protection type shutter, when work, wind turbine blows leaf open
The opening angle of piece 2 and blade 2 is adapted to automatically by the size of air output, and wind turbine is stopped, and 3 rotations exist blade 2 around the shaft
Under gravity under automatic vertical, window 4 is sheltered from, so as to avoid the entrance of dust and rainwater.Due to sinking bending 7 so that most
The blade 2 of lower part is after closure, and just so that blade 2 and the metal plate of forms 1 are kept in one plane, convex bending 8 is leant out
Certain length shelters from opening portion as eaves, plays the role of effective protection.The peace that the forms 1 of shutter pass through setting
Hole 9 is filled to be mounted on wind turbine.
As described above, the plan content given by conjunction with the accompanying drawings and embodiments, can derive similar technical solution.But
Every content without departing from technical solutions of the utility model, it is made by the above technical examples according to the technical essence of the present invention
Any simple modification, equivalent change and modification still fall within the range of technical solutions of the utility model.
