Description

Technical Field

[0001] The invention relates to the technical field of heat preservation blanket storage and release in a solar greenhouse, in particular to a heat preservation device in a solar greenhouse. Background Art

[0002] The solar greenhouse insulation system can be divided into two parts: insulation enclosure structure and insulation blanket. Among them, the insulation blanket plays an important role in reducing the heat exchange between the inside and outside of the greenhouse and increasing the temperature inside the greenhouse.

[0003] There are many types of internal insulation devices on the market. However, the manufacturing technology of internal insulation devices is not mature yet, and internal insulation devices often have many defects. During the use of internal insulation devices, if the operator's clothes are rolled into the roller shutter or the fingers are entangled by the rope, it is very easy to cause danger. In addition, due to uneven force on the reel, the reel tilts after a period of use and needs to be adjusted frequently. It needs to be replaced almost every year, which seriously wastes human resources. Therefore, it is particularly important to design a more intelligent, safe, strong and economical greenhouse internal insulation device.

[0004] In view of the problems existing in the asymmetric solar greenhouse insulation devices in the north, the traditional external insulation method is changed, and an insulation device with an insulation blanket laid from the inside and can be freely retracted is designed to solve the problem that the traditional insulation blanket is exposed to the outside for a long time and is soaked by rain and exposed to the sun, which causes heavy burden on the greenhouse and seriously shortens the service life of the insulation. The internal insulation method can effectively solve such problems, so the design of a new type of internal insulation device in the solar greenhouse will play a very important role in the development of greenhouses in northern my country.
