Problems solved by technology

[0002] The known greenhouses are usually covered with a layer of film, and it is necessary to cover the film with a quilt to prevent the cold. The disadvantages are: the cost of the quilt is high, and it is opaque
The cold protection of the membrane structure building Water Cube is to inflate the double-layer membrane. The disadvantage is that an automatic inflation system is required, which is costly and requires frequent maintenance.

Embodiment Construction

[0008] Such as figure 1 , when covering and fixing the double-layer film: cut two layers of plastic film according to the geometric plane surrounded by the support rod, paste the outer plastic film on the outer top surface of the support rod, insert a high-elastic elastic rod such as carbon fiber into the support rod, and use the elasticity of the elastic rod The outer film is arched to form an arc surface, and then the inner film is pasted on the inner bottom surface of the support rod. Such as figure 2 , when covering the movable double-layer membrane: according to the geometric plane surrounded by the support rods, find several intersection points of the support rods, insert a threaded shaft perpendicular to the two intersecting support rods at each intersection point and penetrate through it, and connect the step below the threaded shaft The rotating shaft of the stepping motor is fixed to the stepping motor and the support rod. Make a covering frame according to the ge...

Abstract

The invention discloses a double-layer film covering method for a greenhouse, and belongs to the technical field of greenhouses. The method can achieve a good cold-proof effect without the need for covering the quilts and inflating the double-layer film. The method has the advantages of light transmission, good heat preservation effect, low cost, and adjustable humidity and temperature.

Description

technical field [0001] The invention relates to the technical field of greenhouses, in particular to a double-layer film covering method for greenhouses. Background technique [0002] Known greenhouses are usually covered with a layer of film, and the film needs to be covered with a quilt to prevent cold. The disadvantages are: the cost of the quilt is high and it is opaque. The cold protection of the membrane structure building Water Cube is to inflate the double-layer membrane. The disadvantage is that an automatic inflation system is required, which is costly and requires frequent maintenance. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a double-layer film covering method for greenhouses. [0004] The technical solution adopted in the present invention is: use the elasticity of the elastic rod to arch the outer film into an arc surface, so that there is more air in the double-...
