[0002] Greenhouse, also known as hot house, is a facility for growing plants that can transmit light, keep warm or heat. In seasons not suitable for plant growth, it can provide a greenhouse growth period and increase production. It is mostly used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees and other plants in low temperature seasons. There are many types of greenhouses, which can be divided into many categories according to different roof frame materials, lighting materials, appearance and heating conditions.
[0003] Existing greenhouses are often single-span single-tooth structures with a lot of invalid space, poor wind resistance, and no facade windows. On rainy days in summer, windows cannot be opened for ventilation and cooling.

[0030] Reference Figure 1-5 The utility model provides an embodiment: a one-span, two-tooth-shaped-top large-span film greenhouse, comprising a plurality of main columns 1, a plurality of composite cross beams 2 fixedly connected between the plurality of main columns 1, the upper ends of the plurality of composite cross beams 2 are fixedly connected with left and right opposite load-bearing rods 3, the upper ends of the plurality of load-bearing rods 3 are fixedly connected with shed poles 4, the left ends of the plurality of load-bearing rods 3 are fixedly connected with inclined rods 6, the middle parts of the lower ends of the plurality of shed poles 4 are fixedly connected with longitudinal rods 5, the upper ends of the plurality of main columns 1 are fixedly connected with water troughs 7, the lower sides of the left ends of the plurality of shed poles 4 are fixedly connected to the upper ends of the water troughs 7, the upper ends of the plurality of composite cross beams 2 are fixedly connected with water troughs 7, the outer sides of the plurality of shed poles 4 are provided with long-life films 8, the right ends of the plurality of shed poles 4 are provided with roll film windows 16, and the outer sides of the roll film windows 16 are provided with long-life films 8.
[0031] Specifically, the stability of the entire greenhouse is ensured by the main columns 1 and the composite beams 2. Both the main columns 1 and the composite beams 2 are rectangular tubes, which have better crop hanging loads than single beams and can be easily expanded to install other equipment. The load-bearing rods 3 support and fix the shed poles 4. The diagonal rods 6 support and fix the load-bearing rods 3. The longitudinal rods 5 support and fix the shed poles 4. The water trough 7 collects and discharges rainwater. Rainwater on the longevity film 8 on the shed pole 4 slides into the water trough 7 to prevent it from dripping onto the plants. The roll film windows 16 are conducive to the smooth discharge of hot air and improve the cooling effect. At the same time, ventilation and cooling can be kept open on rainy days in summer. The roll film windows 16 can be closed by the longevity film 8 on windy days.
[0032] The other ends of the plurality of longitudinal rods 5 are fixedly connected to the upper end of the composite cross beam 2 .
[0033] Specifically, the composite cross beam 2 plays a role in fixing and supporting the longitudinal rod 5 .
[0034] The other ends of the plurality of inclined tie rods 6 are fixedly connected to the upper end of the composite cross beam 2 .
[0035] Specifically, the composite cross beam 2 plays a role in fixing and supporting the diagonal tie rod 6 .
[0036] The upper ends of the multiple composite beams 2 are fixedly connected to film rolling rods 9, the outer sides of the multiple film rolling rods 9 are slidably connected to sliders 10, the outer sides of the multiple sliders 10 are fixedly connected to protection blocks 11, and the interiors of the multiple protection blocks 11 are fixedly connected to bidirectional motors 12.
[0037] Specifically, the slider 10 can slide on the film rolling rod 9 through external driving, drive the protection block 11 to slide, and then drive the bidirectional motor 12 to move vertically. The protection block 11 plays a protective role on the bidirectional motor 12.
[0038] The output ends of the multiple bidirectional motors 12 are all fixedly connected to round rods 13 , the other ends of the multiple round rods 13 are all rotatably connected to the other end sliders 10 , and long-life films 8 are arranged on the outside of the multiple round rods 13 .
[0039] Specifically, the round rod 13 is driven to rotate by the bidirectional motor 12 , which then drives the round rod 13 to reel in the long-life film 8 , and the film roll window 16 is opened. The slider 10 serves to limit the round rod 13 .
[0040] The outer sides of the plurality of shelf poles 4 are all fixedly connected with fixing blocks 14 , and the outer sides of the plurality of fixing blocks 14 are all fixedly connected with electric push rods 15 .
[0041] Specifically, the fixing block 14 plays a role in fixing and supporting the electric push rod 15 .
[0042] The output ends of the lower ends of the plurality of electric push rods 15 are all fixedly connected with the slider 10 .
[0043] Specifically, the electric push rod 15 pushes the slider 10, driving the round rod 13 to roll up the long-life film 8 and move vertically at the same time, thereby ensuring the normal film rolling operation.
[0044] Working principle: The stability of the entire greenhouse is guaranteed by the main column 1 and the composite beam 2. The main column 1 and the composite beam 2 are both rectangular tubes, which have better crop hanging load than a single beam and can be easily expanded to install other equipment. The lower left ends of multiple shed poles 4 are fixedly connected to the upper end of the water trough 7. Rainwater from the longevity film 8 on the shed pole 4 slides into the water trough 7 and will not drip directly on the plants in the middle of the half slope, avoiding pollution to the crops. The film roll window 16 is conducive to the smooth discharge of hot air and improves the cooling effect. At the same time, ventilation and cooling can be often opened on rainy days in summer. When it is necessary to roll up the longevity film 8 on the film roll window 16, the bidirectional motor 12 drives the round rod 13 to rotate, and then drives the round rod 13 to rewind the longevity film 8. At the same time, the electric push rod 15 plays a pushing role on the slider 10, driving the round rod 13 to rewind the longevity film 8 while moving vertically, ensuring the normal operation of the film roll, and the film roll window 16 can be opened and closed.
