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 novel folding and pushing heat preservation device in a solar greenhouse. Technical Background

[0002] China is a major agricultural country. In the past decade, the scale of use of solar greenhouses has been expanding year by year, and people's requirements for greenhouse insulation systems have become increasingly stringent. After several generations, the insulation structure of solar greenhouses has gradually stabilized, but there is still much room for improvement.

[0003] The insulation system of a solar greenhouse can be divided into two parts: an insulation enclosure structure and a movable insulation blanket. During the daytime, the front roof is only covered with plastic film for lighting. When outdoor light weakens, the plastic film is covered with a movable insulation blanket in time to strengthen the insulation of the greenhouse.

[0004] The insulation enclosure structure consisting of three walls on the east, west and north sides and a single slope plastic film is a type of solar greenhouse insulation system. It can effectively maintain indoor heat and reduce heat loss. Walls with different structures, materials and thicknesses have different insulation properties. The ideal wall should have a heat storage layer composed of materials with strong heat absorption and heat storage capabilities on the inside, an insulation layer composed of materials with poor heat conduction and heat dissipation capabilities on the outside, and a heterogeneous composite wall with interlayer insulation in the middle.

[0005] There are many types of roller shutter machines on the market. However, the manufacturing technology of roller shutter machines is still immature, and roller shutter machine equipment often has many defects. During the use of the roller shutter machine, if the operator's clothes are rolled into the roller shutter machine or the fingers are entangled by the rope, personal injury accidents are very likely to occur. Moreover, since each rope is subjected to uneven force, the tightness varies after a period of use, and the tightness of the rope needs to be adjusted frequently, and the pull rope needs to be replaced almost every year. In addition, some of the brackets of the roller shutter machine are buried in the back roof of the solar greenhouse. Over time, it is very destructive to it, or rainwater wets the back wall, causing collapse and serious losses. Therefore, it is particularly important to design a more intelligent, safe, firm and economical greenhouse roller shutter device.

[0006] 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 an asymmetric internal insulation device will play a very important role in the development of greenhouses in northern my country.
