Example 2

Referring to fig. 1 to 4, the difference from embodiment 1 is that: the whole hollow structure that is of control cavity 3, control cavity 3 upper surface is the cambered surface structure, and the lower surface is planar structure, control cavity 3 lower surface is relative with the upper surface of ceiling 1, and control cavity 3 is hollow structure of cavity, furthest reduces the holistic weight of control cavity 3, because control cavity 3 upper surface is the arc structure, lower surface planar structure, when the wind blows, because the wind speed is unanimous all the time, and the distance that the wind walked the cambered surface is longer than planar distance, can lead to the reduction of the atmospheric pressure of cambered surface department for control cavity 3 and the interval between the ceiling 1 change, when the amount of wind is less, the interval is less relatively, and ceiling 1 upper surface wind speed is improved, and the suction of production is also stronger.

Example 3

Referring to fig. 1 to 4, the difference from embodiment 1 is that: the side baffles 2 are connected with the ceiling 1 through the brackets, gaps exist between the bottom edges of the side baffles 2 and the upper surface of the ceiling 1, and the gaps between the side baffles 2 and the ceiling 1 can be used for running wind to gather external wind to enter the upper surfaces of the control cavity 3 and the ceiling 1.

The working principle of the invention is as follows:

when the device is blown into the device from a gap between the ceiling 1 and the side baffle 2 in windy weather, the distance between the upper surface of the control cavity 3 and the lower surface of the control cavity 3 is shorter than that between the upper surface of the control cavity 3 due to the longer distance between the upper surface of the control cavity 3, so that the gas flow rate above the control cavity 3 is faster, the gas pressure above the control cavity 3 is smaller, the whole control cavity 3 has a lifting effect, and the distance between the control cavity 3 and the upper surface of the ceiling 1 is changed after lifting;

when the air enters strong wind weather, the lifting height of the control cavity 3 is higher, the more the amount of air flowing into the gap is, the more the air quantity can enter the exhaust hole 7 is, and the more the heat dissipation effect is;

when the weather with weaker wind force is met, the lifting height of the control cavity 3 is relatively low, under the condition that the gas flow is kept unchanged, the space at the gap is reduced, so that the flow rate of the gas is accelerated, the air pressure on the ceiling 1 is reduced due to the fact that the flow rate of the gas is faster, the gas below the ceiling 1 is easier to flow out from the exhaust hole 7, and the heat dissipation capacity of the ceiling 1 is improved;

when encountering heavy rain and heavy wind weather, the rainwater can drop downwards from the highest position of the ceiling 1 to the effect of gathering is produced inside the rainproof fish scale 5, finally the acting force of the torsion spring of the rainproof fish scale 5 customer service is pressed downwards, and one end of the drain hole 6 of the rainproof fish scale 5 is bent downwards, so that the rainwater is prevented from being flushed into the exhaust hole 7 in heavy wind and heavy rain weather, the drain hole 6 can drain slowly outwards, and the problem of accumulated water can be solved.
