[0021] In this embodiment: when the device is used to ventilate and dissipate heat in the factory building, the hot air in the factory building circulates upward, passes through the ventilation slots, and is discharged outward through the gap between the ceiling 1 and the rain shelter 2, thereby achieving a heat dissipation effect. When it rains, rainwater drops on the ceiling 1, and drops downward along the inclined surface of the ceiling 1 onto the guide plate 8, and then is discharged outward through the drainage hole 9, thereby preventing rainwater from directly dripping into the factory building;

[0022] In snowy weather, the blocking mechanism is activated to block the ventilation slots to prevent snowflakes from drifting into the factory building.

[0023] Please refer to Figure 2 A secondary keel 7 is fixedly connected to the bottom end of the ceiling 1 , one end of the secondary keel 7 is fixedly connected to the outer side of the main keel 6 , and the other end of the secondary keel 7 is fixedly connected to the inner side of the rain shelter 2 .

[0024] In this embodiment: the secondary keel 7 is used to improve the connection force between the ceiling 1 and the rain shelter 2, making the device more stable.

[0025] Please refer to Figure 2 and Figure 3 The blocking mechanism includes an electric push rod 10 rotatably mounted on the outside of a guide plate 8, and a connecting plate 11 is rotatably mounted on the top of the electric push rod 10; a closing plate 13 is rotatably mounted between the two fixed plates 3, and the connecting plate 11 is integrally formed on the outer wall of a closing plate 13, and the ends of the two closing plates 13 that are away from each other are rotatably connected to the fixed plate 3 through a rotating shaft, one end of the two rotating shafts penetrates to the outside of a fixed plate 3, and one end of the two fixed plates 3 is connected to a gear 4, the two gears 4 are meshed with each other, and a protective box 5 for protecting the two gears 4 is fixedly mounted on the outside of a fixed plate 3.

[0026] In this embodiment: when the closing plate 13 is in the open state, by starting the electric push rod 10, the output end of the electric push rod 10 pulls a closing plate 13 to rotate through the connecting plate 11, and the closing plate 13 rotates around the rotating shaft. At this time, the rotating shaft drives the gear 4 connected to it to rotate, and the gear 4 drives another gear 4 to rotate synchronously in the opposite direction. The other gear 4 mobilizes another closing plate 13 to rotate synchronously through the rotating shaft connected to it. At this time, the two closing plates 13 rotate synchronously in the opposite direction, and the rotation direction is from top to bottom, until the bottom of the closing plate 13 contacts the top of the guide plate 8, the ventilation slot can be closed to prevent snowflakes from falling into the factory building or snowflakes from accumulating on the guide plate 8 and entering the factory building.

[0027] Please refer to Figure 2 A sealing plate 12 is fixedly installed between the two fixing plates 3 below the butt joint of the two closing plates 13 in the closed state, and a rubber seal is installed at the contact position between the top of the sealing plate 12 and the two closing plates 13.

[0028] In this embodiment: during the closing process of the two closing plates 13, the bottom end of the closing plate 13 squeezes the rubber seal, and the rubber seal is deformed under pressure, thereby improving the sealing performance of the contact position between the two, thereby preventing water generated by melting snowflakes from dripping into the factory building.
