Description

Heat preservation and sun shading method for greenhouse

Technical Field

The invention relates to the technical field of greenhouses, in particular to a heat preservation and sun shading method for a greenhouse.

Background

The greenhouse is a constant-temperature protection structure for vegetable planting, and people can plant vegetables in various seasons in the greenhouse so as to meet the requirement that people can eat out-of-season vegetables in different seasons, particularly in winter, and also meet the requirement of people on fresh vegetables.

The existing greenhouse mainly comprises a steel frame structure and a transparent plastic film outside the steel frame structure, wherein an insulating layer is required to cover the outside of a heat-insulating film of the greenhouse at night in winter to keep the temperature in the greenhouse, the existing greenhouse insulating layer is a roller shutter type one-layer or multi-layer quilt, the quilt is made of non-woven fabrics, PE (polyethylene) fabrics or woven fabrics and the like, the insulating layer is light-proof, the insulating layer of the structure is required to be put down at night in winter to cover the heat-insulating film of the greenhouse, and sunlight is coiled on the greenhouse in daytime to penetrate through the heat-insulating film to shine into the greenhouse. Therefore, the heat insulation facility with the structure needs to roll and place the heat insulation layer every day, occupies manpower, is troublesome to operate, and wastes time and labor. In summer, the temperature is too high, the temperature in the greenhouse is too high, the growth of vegetables is not facilitated, the heat insulation film of the greenhouse needs to be manually removed, the operation is troublesome, the labor is occupied, and time and labor are wasted.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example one

Referring to fig. 1 and 2, and fig. 6 and 7, in the method for keeping warm and shading sunlight of a greenhouse of the present embodiment, a greenhouse frame 1, for example, a steel-structured greenhouse frame, is first provided, a transparent plastic film 2 is provided on the periphery of the greenhouse frame 1, at least one transparent bubble film 3 is covered on the top of the plastic film 2, the edge of the bubble film 3 can be adhered to the plastic film 2, and a plastic film 2 is laid on the outermost layer of the bubble film to fix and strengthen the warm keeping function. Of course, the outer surfaces of the two ends of the plastic film 2 can be pasted with bubble films. A plurality of bubbles 31 are uniformly distributed on the surface of the bubble film 3, and the bubbles 31 are filled with gas. The bubble film forms a film for isolating the inside and the outside of the greenhouse and a gas heat exchange isolation layer, so that the heat exchange inside and outside the greenhouse is isolated, and a good heat insulation effect is achieved. The transparent bubble film is used as a heat preservation layer, is transparent and heat-preserving, can transmit light without being rolled up in the daytime, can be used for plant growth in the greenhouse by allowing sunlight to penetrate through the bubble film 3 and the plastic film 2 to shine into the greenhouse, and can play a good heat preservation role at night, so that the roller shutter type heat preservation layer is not used in the greenhouse, and the heat preservation layer is not rolled up and put down every day. Saving labor and convenient use. Referring to fig. 6, the bubble film 3 may be a shock-proof dot bubble film, and a plurality of dot-shaped bubbles 31 may be arranged on the surface. Referring to fig. 7, the bubble film 3 may be a strip-shaped inflated bubble film, and a plurality of strip-shaped bubbles 31 are distributed on the surface.

The bubbles 31 of the bubble film 3 are filled with an inert gas. For example, helium, neon, argon, etc. have a good heat preservation effect because the temperature is largely transferred by molecular vibration in the air, but the inert gas has poor activity and poor heat conductivity, and therefore, the bubble film 3 is filled with the inert gas to better isolate the heat exchange inside and outside the greenhouse.

Example two

Referring to fig. 3, the structure of the present embodiment is substantially the same as that of the first embodiment, except that: two layers of transparent bubble films 3 are covered on the periphery of the plastic film 2, and the bubbles 31 of the bubble film 3 on the lower layer and the bubbles 31 of the bubble film 3 on the adjacent upper layer are arranged in a staggered mode, so that a complete gas isolation layer for isolating the inside and the outside of the greenhouse is formed, and the heat insulation effect can be further enhanced. Of course, the number of layers of the bubble film is not limited to one or two, and may be two or more.

EXAMPLE III

Referring to fig. 4, the structure of the present embodiment is substantially the same as that of the second embodiment, except that: a sun-shading layer is laid above the uppermost air bubble film 3, and can be nylon sun-shading net or non-woven fabric. A layer of soil 4 or cement covered completely may be sprayed on the plastic film 2 on the outermost side, or a layer of cloth may be laid and then a layer of soil 4 or cement covered completely may be sprayed on the cloth. The air bubble film 3 plays a good role in heat preservation, and meanwhile, the sun-shading layer plays a good role in sun shading. The structure is suitable for breeding animals in a greenhouse.

Referring to fig. 5, the soil 4 or cement sprayed may also be sprayed at intervals, and a gap is left between two adjacent soil 4 or cement.

The foregoing is illustrative of the best mode of the invention and details not described herein are within the common general knowledge of a person of ordinary skill in the art. The scope of the present invention is defined by the appended claims, and any equivalent modifications based on the technical teaching of the present invention are also within the scope of the present invention.
