Plate 2, a closing on the left side in figure, a unlatching on the right, left arrow represent that outside wind and rain enters in roofing ventilation unit 4
Direction, right side arrow represents the direction flowed from inside to outside of air-flow.
Following defect be present in above-mentioned traditional valve plate device：
Gap be present between valve plate and ventilator column, if running into extreme wind rainy day gas, rainwater is splashed into, and valve plate can have product
Water drainage；Steel wire rope coiling, which is realized, opens, and realizes during closing and closes by valve plate own wt, if running into the extreme wind rainy day
Gas, valve plate can produce vibrating noise and the infiltration inflow interior from gap；The maximum opening angle of valve plate is 60 degree or so, because of valve
Plate opening angle is limited, and ventilation relative can be reduced.
Utility model content
The purpose of this utility model is that to solve the above problems and provided rotating during a kind of side vertically installed is opened
Valve plate headstock gear for roofing ventilation unit.
The utility model is achieved through the following technical solutions above-mentioned purpose：
Rotating valve plate headstock gear during a kind of side for roofing ventilation unit is opened, is installed in the roofing ventilation unit
And by the vertical ventilator column, including valve plate and push-rod electric machine, the valve plate include multiple valve plate units, the two of homonymy
Entablature and sill are installed between the individual ventilator column, is provided between the entablature and the sill
Multiple laterally homogeneous spaced vertical pivots, multiple vertical valve plate units are installed on multiple described correspondingly respectively
On vertical pivot and it can rotate freely, one end of more branch cross bars is fixed with one-to-one multiple valve plate units respectively to be connected
Connect, the other end of the more branch cross bars is rotatably connected with total cross bar by hinge respectively, more branch cross bars with it is described total
Cross bar forms hinge linkage, one end of cross lever and the valve plate unit close to the push-rod electric machine or the hinge
Linkage is fixedly connected, and the other end of the cross lever is rotatably connected with the output shaft of the push-rod electric machine by hinge；
It is close to each other between the adjacent valve plate unit of each two or partially overlap when the valve plate is closed.
Preferably, the vertical pivot is located at the center of the corresponding valve plate unit.
Preferably, one end of the cross lever is fixedly connected with the valve plate unit close to the push-rod electric machine.
The beneficial effects of the utility model are：
The utility model passes through more by by multiple valve plate unit vertical arrays and being rotatably mounted on multiple vertical pivots
Branch cross bar and total cross bar form hinge linkage and driven by push-rod electric machine, so as to realize multiple valve plate units in the horizontal direction
Rotation control, finally realize whole valve plate keying control；Whole valve plate is placed in the side of ventilator column and substantially contour,
And the outside of ventilator column can be located at, can effectively it avoid because splashing rain drainage caused by extreme wind rainy day gas, rainwater can be because
The stop of vertical valve plate and flow directly into outdoor roofing；When the output shaft of push-rod electric machine is retracted, all valve plate units are in hinge
Realize united opening under the drive of linkage, 90 degree unlatchings of rotation in can be achieved, now ventiduct roadbed be maximum, close to opening
Open form ventilator ventiduct roadbed；Overall execution mechanism is rigid hinge linkage, ensure that valve plate structural stability and
Resisting wind press capacity, it is greatly reduced because of noise caused by valve plate vibrations.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As Figure 1-Figure 5, rotating valve plate headstock gear during the side described in the utility model for roofing ventilation unit is opened
It is installed in roofing ventilation unit 4 and by vertical ventilator column 1, roofing ventilation unit 4 is located at industrial premises roofing 6
Top, the side in opening rotating valve plate headstock gear include valve plate and push-rod electric machine 8, the valve plate includes multiple valve plate units
7, entablature 9 and sill 10 are installed between two ventilator columns 1 of homonymy, between entablature 9 and sill 10
Multiple laterally homogeneous spaced vertical pivots 11 are installed, multiple vertical valve plate units 7 are installed on more correspondingly respectively
On individual vertical pivot 11 and it can rotate freely, the center of the valve plate unit 7 corresponding to of vertical pivot 11, the one of more branch cross bars 13
End is fixedly connected with one-to-one multiple valve plate units 7 respectively, and the other end of more branch cross bars 13 is logical with total cross bar 14 respectively
Cross hinge rotatable connection, more branch cross bars 13 and total cross bar 14 form hinge linkage, one end of cross lever 12 with it is close
The valve plate unit 7 of push-rod electric machine 8 is fixedly connected (as needed, can also be with some part ratio in the hinge linkage
As total cross bar 14 connects), the other end of cross lever 12 is rotatably connected with the output shaft of push-rod electric machine 8 by hinge；The valve
It is close to each other between each two adjacent valve Slab element 7 or partially overlap when plate is closed.
As Figure 2-Figure 5, side described in the utility model in opening rotating valve plate headstock gear using when have opening and closing
Two states, the valve plate in Fig. 2 shown in left side are closed, and the valve plate on right side is in opening；The master that valve plate is closed
It is to stop that outdoor wind and rain is got in want function, so left arrow represents the side that outside wind and rain enters in roofing ventilation unit 4
To the major function that valve plate is opened is that indoor air flow is expelled into outdoor to realize ventilation function, so right side arrow represents
The direction that air-flow flows from inside to outside；During valve plate contract fully, rainwater is hit down can flow directly into outdoor roofing on the outside of closure valve plate,
The rain Seepage that floatd caused by extreme wind rainy day gas can effectively be prevented；During valve plate full open, ventiduct roadbed is maximum, close to
Open type ventilator ventiduct roadbed.
Above-described embodiment is preferred embodiment of the present utility model, is not the limit to technical solutions of the utility model
System, as long as the technical scheme that can be realized without creative work on the basis of above-described embodiment, is regarded as falling into
In the rights protection scope of the utility model patent.
