The utility model discloses further set up to: the edge of the shielding plate is provided with a downward inclined flange.

Through adopting above-mentioned technical scheme, the shielding plate can provide better rain-proof ability.

The utility model discloses further set up to: the air duct is arranged along the inner side of the wall of the factory building main body, and an inner air vent is formed in the air duct.

Through adopting above-mentioned technical scheme, when having the heat source in the factory building main part, can also utilize interior air vent to lead out the hot-air of factory building main part.

The utility model discloses further set up to: the internal thread of the internal vent hole is connected with a plug.

Through adopting above-mentioned technical scheme, the user of service can decide whether to open interior air vent according to the circumstances of reality, and it is convenient to use.

The utility model discloses further set up to: a plurality of air ducts are arranged on the same connecting pipe.

Through adopting above-mentioned technical scheme, a plurality of air ducts on the same connecting pipe can disperse on the wall of factory building main part, reinforcing air flow's homogeneity.

To sum up, the utility model discloses a beneficial technological effect does:

the utility model discloses utilize the ventilation pipe as the guide channel to the difference in height that utilizes factory building main part itself produces the difference in temperature, makes the air current that produces the upflow in leading to the minute pipe, comes to provide drive power for rotatory ring, thereby under the less strong condition of natural wind, the circulation of air ability in the factory building main part is still stronger.

Detailed Description

The present invention will now be described more fully hereinafter with reference to the accompanying examples.

Referring to the attached drawing 1, the automatic ventilation factory building comprises a factory building main body 1, wherein the factory building main body 1 is of a steel structure, and the roof of the factory building main body 1 is of a pitched roof structure. The fixed ventilation pipe 2 that is provided with in roof of factory building main part 1, combines figure 2, and ventilation pipe 2 communicates the upper and lower both sides on factory building main part 1 roof. A driving cylinder 3 is arranged in the ventilation pipe 2 in a penetrating way, the lower end of the driving cylinder 3 is closed, the upper end of the driving cylinder is rotatably provided with a rotating ring 4, and the inner side and the outer side of the rotating ring 4 are both provided with rotating blades 5. The rotating ring 4 is provided with a wind cap 6, the lower part of the wind cap 6 is fixed with a circle of shielding plates 7, and the edges of the shielding plates 7 are provided with downward flanges 8.

The ventilation pipe 2 is fixedly connected with the driving cylinder 3 through a plurality of connecting pipes 9, the connecting pipes 9 are communicated with the driving cylinder 3, and the connecting pipes 9 penetrate through the ventilation pipe 2. Connecting pipe 9 UNICOM is provided with a plurality of air ducts 10, combines figure 3, and air duct 10 lays along the inside wall of factory building main part 1, and the one end that connecting pipe 9 was kept away from to air duct 10 is located the bottom in the factory building main part 1 wall outside. The air duct 10 is provided with an inner vent hole 11, and the inner vent hole 11 is internally threaded with a plug 12.

The working principle of the embodiment is as follows: generally, the temperature of the ground is slightly higher than the temperature of the air, and because a large height difference exists between the roof of the plant main body 1 and the ground, a significant temperature difference also exists, so that the lower end of the ventilation pipe 2 is high-temperature low-density gas, and the upper end of the ventilation pipe 2 is low-temperature high-density gas, so that an upward flowing air flow will occur in the ventilation pipe 2, and thus the air flow can drive the rotating ring 4 to rotate through the rotating blades 5 on the inner side of the rotating ring 4. When the rotating ring 4 rotates, the air between the ventilating pipe 2 and the driving cylinder 3 is forced to flow upwards by the rotating blades 5 on the outer side, so that the air flow in the plant main body 1 is promoted. Thus, even when natural wind is weak, the plant main body 1 can have good ventilation capability. The hood 6 can provide the pivoted drive power for the swivel becket under the circumstances that has the natural wind to the hood 6 can play the effect that keeps off the rain with shielding plate 7 together, prevents that the rainwater from entering into in the ventilation pipe 2. When there is the heat source in factory building main part 1, can also utilize interior air vent 11 to lead out the hot-air of factory building main part 1.

The above, only be the utility model discloses the embodiment of preferred does not restrict according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
