Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this reality
It is described in detail with new.
As shown in Figure 1-Figure 3, the fire control smoke exhausting device, its structure mainly include：
First rain cover 11 and the second rain cover 21；
The bottom of second rain cover 21 is provided with several carrier bars 31；
The top of second rain cover 21 is provided with motor rack 52, and motor 51, the output of motor 51 are provided with motor rack 52
Axle is fixedly connected with the rotating shaft of the first rain cover 11；
First rain cover 11 is provided with several first exhaust smoke holes 12；Second rain cover 21 is provided with several
Second exhaust smoke hole 22；The first exhaust smoke hole (12) on first rain cover (11) and the second smoke evacuation on the second rain cover (21)
The position in hole (22) is mutually correspondingly arranged.
During fine day, by the first exhaust smoke hole 12 on the first rain cover 11 and the second row on the second rain cover 21
The position of cigarette hole 22 overlaps.
As preferable embodiment, the first rain cover 11 is provided with support bar 53, and the bottom of support bar 53 has support wheel
54, support wheel 54 is pressed on the second rain cover 21.The structure can cause most of quality of the first rain cover 11 by support bar
53 and support wheel 54 undertake.
According to different needs, the first exhaust smoke hole 12 is circular or rectangle, and the second exhaust smoke hole 22 is also circular or rectangle.No
By being circular or rectangle, the shape and quantity of the first exhaust smoke hole 12 and the second exhaust smoke hole 22 all should work as it is identical, to realize the two
Overlap.For example, the first exhaust smoke hole 12 and the second exhaust smoke hole 22 are 4.
In use, carrier bar 31 is directly fixedly connected on outlet flue 41.After installation is complete, it should be ensured that the
Outlet flue 41 is completely covered two rain covers 21.From the point of view of cost is reduced, the first rain cover 11 and the second rain cover
21 main part is umbellate form, and top is circle.
With reference to shown in figure 4, when weather is fine, the first exhaust smoke hole 12 and the second exhaust smoke hole 22 are completely superposed, and flue gas is from smoke
After mouthfuls 41 outflows, through the first exhaust smoke hole 12 and the second exhaust smoke hole 22 it is in line enter air in.
With reference to shown in figure 5 and Fig. 6, during wind and rain weather, start motor 51 and rotate the first rain cover 11, make the first exhaust smoke hole 12
Mutually stagger with the position of the second exhaust smoke hole 22, so that the first exhaust smoke hole 12 and the second exhaust smoke hole 22 are completely misaligned.Raindrop
Under wind action, move from left to right as shown in the figure, through the first exhaust smoke hole 12 after beat on the second rain cover 21.Due to
One exhaust smoke hole 12 and the position of the second exhaust smoke hole 22 are offset from each other, therefore are had between the first exhaust smoke hole 12 and the second exhaust smoke hole 22
There is a certain distance L, enter outlet flue 41 so as to avoid after raindrop sequentially pass through the first exhaust smoke hole 12 and the second exhaust smoke hole 22
It is internal.
Also, because the first exhaust smoke hole 12 and the second exhaust smoke hole 22 are completely misaligned, so flue gas exists in discharge process
Certain resistance, but because there is the presence of wind, first exhaust smoke hole 12 in left side just becomes tunnel inlet, it is right in malleation
First exhaust smoke hole 12 of side just becomes ducting outlet, in negative pressure.The then sky between the first rain cover 11 and the second rain cover 21
Between just become the air channel of air lateral flow.Now, flue gas can accelerate flowing from left to right under the action of the forces of the wind, and then
So that the air pressure between the first rain cover 11 and the second rain cover 21 is less than between the second rain cover 21 and outlet flue 41
Pressure, make the flue gas of the second rain cover 21 and outlet flue 41 accelerate to flow up, thus largely compensate for due to the
One exhaust smoke hole 12 and the position of the second exhaust smoke hole 22 stagger completely caused by smoke evacuation resistance, realize the smoke evacuation under wind and rain weather
Speed effect substantially suitable with the flue gas velocity under fine day situation, it is ensured that smoke discharging effect is not deteriorated because of Changes in weather.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.Finally illustrate, with
Upper embodiment is only to illustrate the technical solution of the utility model and unrestricted, although with reference to preferred embodiment to the utility model
It is described in detail, it will be understood by those within the art that, the technical solution of the utility model can be repaiied
Change or equivalent substitution, without departing from the objective and scope of technical solutions of the utility model, it all should cover in the utility model
Right among.
