[0024] The utility model provides a plastic greenhouse with vertical natural ventilation system, like Figure 1As shown, it comprises: a plastic greenhouse body 1, a first film sealing piece, a second film sealing piece, a wind port turning piece 2, a third film sealing piece and a fourth film sealing piece. The plastic greenhouse body 1 comprises a first film 11 and a first arched frame 12. The first film 11 is wrapped on the first arched frame 12. The top of the first film 11 is provided with an upper air vent 15. The two sides of the bottom of the first film 11 are provided with a first air vent 13 and a second air vent 14. The first film sealing piece is used to be detachably fixedly connected with the plastic greenhouse body 1 to seal the first air vent 13. The second film sealing piece is used to be detachably fixedly connected with the plastic greenhouse body 1 to seal the second air vent 14. The wind port turning piece 2 is arranged above the upper air vent 15 and is fixedly connected with the first arched frame. The two sides of the wind port turning piece are provided with inclined third and fourth air vents 23 and 24 which are communicated with the upper air vent 15. The third film sealing piece is used to be detachably fixedly connected with the wind port turning piece 2 to seal the third air vent 23 and to make the rainwater falling on the third film sealing piece slide off. The fourth film sealing piece is used to be detachably fixedly connected with the wind port turning piece 2 to seal the fourth air vent 24 and to make the rainwater falling on the fourth film sealing piece slide off. By arranging the wind port turning piece 2 at the upper air vent 15 of the plastic greenhouse body 1, the upward upper air vent 15 is changed into two inclined third and fourth air vents 23 and 24. While effectively ensuring the ventilation effect, after the third and fourth air vents 23 and 24 are sealed by the third and fourth film sealing pieces in rainy days, the rainwater falling on the inclined third and fourth film sealing pieces will directly slide off and will not accumulate on the third and fourth film sealing pieces. The structure is simple, convenient to use and can effectively improve the water accumulation phenomenon at the top of the plastic greenhouse and prolong the service life of the plastic greenhouse.
[0025] In a preferred embodiment, the wind port turning piece 2 is in an arched structure which has good stability and strength and can withstand certain external forces such as wind and rain. At the same time, the arched structure is also conducive to the sliding of rainwater and avoids the accumulation of rainwater on the wind port turning piece 2.
[0026] In a preferred embodiment, the wind port turning piece 2 comprises a second arched frame 21 and a second film 22. The second film 22 is wrapped on the second arched frame 21. The two sides of the second film 22 are provided with third and fourth air vents 23 and 24. The two ends of the bottom of the second arched frame 21 are fixedly connected with the positions outside the two ends of the upper air vent 15 of the first arched frame 12. The wind port turning piece 2 composed of the second arched frame 21 and the second film 22 has a simple structure and is easy to install and maintain. The fixed connection mode with the first arched frame 12 ensures the stability of the wind port turning piece 2 and prevents it from being easily moved or damaged by external forces.
[0027] In a preferred embodiment, the height of the second arched frame 21 is 0.9-1.1 m, preferably 1 m, and the distance between the two ends of the bottom of the second arched frame 21 is 2.5-3.5 m, preferably 3 m. The appropriate height and width parameters ensure that the air inlet turning piece 2 can effectively guide the ventilation without occupying too much space. The design of the height and width also takes into account the sliding angle of the rainwater, so that the rainwater can smoothly slide off the air inlet turning piece 2.
[0028] In a preferred embodiment, the width of the third air inlet 23 is 1.4-1.5 m, preferably 1.45 m, and the fourth air inlet 24 is arranged opposite to the third air inlet 23, and the width of the fourth air inlet 24 is 1.4-1.5 m, preferably 1.45 m. The specific width of the air inlet can ensure sufficient ventilation, while also not causing excessive heat loss or the entry of external pests due to the air inlet being too large. The oppositely arranged air inlets are conducive to air convection, improving the ventilation effect.
[0029] In a preferred embodiment, the third air inlet 23 and the fourth air inlet 24 are provided with insect-proof nets.
[0030] In a preferred embodiment, the air inlet turning piece 2 further comprises a first clamping groove 25 formed by a clamping member and a plurality of first clamping springs. The first clamping groove 25 is arranged along the circumference of the third air inlet 23, and the circumferential edge of the third shed film sealing member is fixed in the first clamping groove 25 by the first clamping springs. The design of the clamping groove and the clamping spring makes the installation of the shed film sealing member more secure and less likely to fall off. At the same time, this connection method facilitates the disassembly and replacement of the shed film sealing member, improving the convenience of maintenance.
[0031] In a preferred embodiment, the air inlet turning piece 2 further comprises a second clamping groove 26 formed by a clamping member and a plurality of second clamping springs. The second clamping groove 26 is arranged along the circumference of the fourth air inlet 24, and the circumferential edge of the fourth shed film sealing member is fixed in the fourth clamping groove by the second clamping springs. Similar to the connection method of the third air inlet 23, the design ensures the stability and detachability of the fourth air inlet 24 shed film sealing member, facilitating maintenance and use.
[0032] In a preferred embodiment, the plastic shed body 1 further comprises a reinforcing frame 16 fixedly connected to the top of the first arched frame 12 to reinforce the position of the upper air inlet 15. The reinforcing frame 16 enhances the structural strength of the upper air inlet 15, preventing deformation or damage of the air inlet due to long-term use or external forces. This improves the overall stability and service life of the shed.
[0033] In a preferred embodiment, the width of the plastic greenhouse body 1 is 11-13 m, preferably 12 m, and the height of the plastic greenhouse body 1 is 4.4-4.6 m, preferably 4.5 m. The appropriate width and height parameters make the interior space of the greenhouse large enough to meet the planting requirements of different crops. At the same time, the stability and cost factors of the greenhouse are also considered. On the premise of ensuring the use effect, the construction cost is reduced as much as possible.
[0034] In a preferred embodiment, the plastic greenhouse body 1 further comprises a third clamping groove formed by a clamping piece, a fourth clamping groove formed by a clamping piece, a plurality of third clamping springs, and a plurality of fourth clamping springs. The third clamping groove is arranged along the circumference of the first ventilation port 13, and the circumferential edge of the first film sealing piece is fixed in the third clamping groove by the third clamping springs. The fourth clamping groove is arranged along the circumference of the second ventilation port 14, and the circumferential edge of the second film sealing piece is fixed in the fourth clamping groove by the fourth clamping springs. The connection mode of the ventilation port turning piece 2 is similar, which ensures the stability and detachability of the bottom ventilation port film sealing piece, and facilitates flexible sealing or opening of the ventilation port according to actual needs, so as to adjust the environmental conditions in the greenhouse.
