[0002] Vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It allows people to eat off-season vegetables. Generally, vegetable greenhouses use bamboo or steel structure frames, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film effectively prevents the loss of carbon dioxide produced by the growth of vegetables inside, making the greenhouse have a good thermal insulation effect.
[0003] However, in order to keep the temperature in the greenhouse constant, the greenhouse needs to be ventilated and cooled when the temperature is too high. Usually, personnel manually open and close the ventilation channels, which has low work efficiency. In addition, the insulation film is often hooked on the frame and lacks a fixed structure, which makes the insulation film easy to fall off, causing irreversible damage to the vegetables.
