Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model relates to a plastic greenhouse that provides insulation and cold protection in winter and cooling and rain protection in summer. The greenhouse has a span of 6.0-8.0m, a shoulder height of 1.7-2.0m, and a ridge height of 3.4-3.8m.

[0019] The inner insulation frame 2 is located inside the greenhouse, above shoulder height. The two ends of the arch rod are fixedly connected to the greenhouse frame 1, with the connection point located 5-10cm below the shoulder. The inner insulation frame 2 is connected as a whole by 2-3 longitudinal tie rods 6. Specifically, the greenhouse frame 1 is a Φ32mm galvanized steel pipe, and the inner insulation frame 2 and the longitudinal tie rods 6 are Φ25mm galvanized steel pipes.

[0020] The top vertical ventilation opening 3 is located on one side of the ridge of the greenhouse, at a distance of not less than 1.2m from the ridge, and the height of the ventilation opening is not less than 0.6m. The top is fixedly connected by a longitudinal tie rod 6.

[0021] The greenhouse is equipped with bottom ventilation openings 5 ​​on both sides, with a height of 1.2m-1.4m.

[0022] The ear-shaped support 4 is located on the outside of the bottom ventilation openings 5 ​​on both sides of the greenhouse. The upper end of the ear-shaped support rod 7 is connected to the outside of the greenhouse frame 1, with the connection point located at the shoulder of the greenhouse. The lower end is buried in the soil, and the lower end is 0.5m away from the bottom of the greenhouse frame 1. The ear-shaped support rod 7 is a galvanized steel pipe with a diameter of 25mm, and one is set every 2-3 greenhouse frames 1.

[0023] The interauricular vent 8 is located on the interauricular support rod 7, and the height of the interauricular vent 8 is not less than the height of the bottom vents 5 on both sides of the frame.

[0024] The greenhouse frame 1 has a slot 9 at the shoulder and the connection between the inner insulation frame 2 and the greenhouse frame to facilitate the covering of the insulation material. When covering with plastic film, the outer frame is covered as a whole, while the area below the shoulder of the greenhouse frame 1 and the inner insulation frame 2 are covered separately. The opening and closing of the plastic film is controlled by the film rolling device 10.

[0025] More specifically, when the temperature is low in winter, all the frame supports are covered with plastic film. The inner insulation frame 2 and the ear support rod 7 are staggered and connected to the greenhouse frame 1 to form a double-layer insulation cover.
