[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that the rainproof component 8 includes a support rod 81, a rainproof plate 82, a hydrophobic layer 84, and a first inclined plate 87. The rainproof plate 82 is positioned above the ventilation fan 7 and the non-powered hood 9. A hydrophobic layer 84 is fixed to the surface of the rainproof plate 82. Support rods 81 are positioned on both sides of the lower end of the rainproof plate 82, and the first inclined plate 87 is fixed to the upper end of the support rods 81.

[0032] By adopting the above technical solution, the support rod 81 is fixed to the top of the pigsty, the rainproof plate 82 can block rain and snow, the water-repellent layer 84 facilitates the flow of rainwater, and the first inclined plate 87 can increase the contact area between the support rod 81 and the rainproof plate 82.

The second inclined plate 85 is fixed to the upper end of the supporting inclined rods 86.

[0034] By adopting the above technical solution, the supporting diagonal rod 86 at the upper end of the horizontal plate 83 can provide auxiliary support for the rainproof plate 82, making its structure more stable. The second diagonal plate 85 can increase the contact area between the supporting diagonal rod 86 and the rainproof plate 82, resulting in better stability.

[0035] In this embodiment, the support rod 81 is fixed to the top of the pigsty, the rainproof plate 82 can block rain and snow, the hydrophobic layer 84 facilitates the flow of rainwater, the first inclined plate 87 can increase the contact area between the support rod 81 and the rainproof plate 82, the support inclined rod 86 at the upper end of the horizontal plate 83 can provide auxiliary support for the rainproof plate 82, making its structure more stable, and the second inclined plate 85 can increase the contact area between the support inclined rod 86 and the rainproof plate 82, resulting in better stability.

[0036] The structure and working principle of the ventilation structure 3, which consists of a ventilation window, a top plate, ventilation holes, a buffer pad, a rotating shaft, a baffle, a ventilation mesh plate, a magnetic block, an electromagnet, and a gas-gathering hood, and the ventilation fan 7, have been disclosed in Chinese Patent Application No. 202322992706.8, which discloses a ventilation device for pig farms. The working principle of the ventilation structure 3 is to open and adjust the magnetic poles of the electromagnet so that the electromagnet and the magnetic block attract each other to open the baffle for ventilation, or close the baffle to stop ventilation. Air enters the ventilation window from the ventilation mesh plate, then enters the gas-gathering hood through the ventilation holes, and finally enters the ventilation sub-pipe 2. The working principle of the ventilation fan 7 is to convert the mechanical energy of rotation into gas pressure energy and kinetic energy, and then transport the gas out.

This causes the ventilation structure 3 in the pigsty 3 to draw the air from the pigpen 4 into the ventilation sub-pipe 2, and then into the ventilation riser 6 through the ventilation main pipe 1, completing the ventilation of the pigsty. The deodorizing plate 53 is snapped into the mounting plate 52. After the polluted air enters the deodorizing box 51, the activated carbon plate 55 can filter it, oxidizing and adsorbing the odor inside to prevent pollution of the outside air. The auxiliary structure 54 can be installed by fixing the side plate 56. The air can be further treated by placing the bio-enzyme air purifier in the drawer 541 of the mesh box 542 for further purification. The protective mesh plate 543 can prevent the purifier from being blown out by the wind. The support rod 81 is fixed to the top of the pigsty, and the rainproof plate 82 can block rain and snow. The hydrophobic layer 84 facilitates the flow of rainwater. The first inclined plate 87 can increase the contact area between the support rod 81 and the rainproof plate 82. The support inclined rod 86 at the top of the horizontal plate 83 can provide auxiliary support for the rainproof plate 82, making its structure more stable. The second inclined plate 85 can increase the contact area between the support inclined rod 86 and the rainproof plate 82, resulting in better stability.
