Description

Double-layer frameless inflatable closed heat-insulation plastic film greenhouse

Description

1. Field of the invention

The invention relates to the field of plastic film greenhouses, in particular to a double-layer frameless inflatable closed heat-insulation plastic film greenhouse.

2. Background of the invention

With the rapid development of the industrial and agricultural technology level in China, the wide application and popularization of the agricultural science and technology greatly improve the material living level of people. Especially, the vegetable baskets in winter are various in variety and good in quality, the simple life mode that only radish and Chinese cabbages exist in winter in the past is thoroughly changed, and the vegetable baskets are popularized and used by virtue of the plastic greenhouse.

In recent years, agricultural plastic film greenhouses are developed from simple bamboo and wood structures and steel structures to frame plastic film structures, glass structures and the like, the scale and the space are increased more and more, and the cost is also increased more and more. The luxurious greenhouse with high cost not only needs more funds and a large amount of materials, but also has longer construction time (about two months), and some times even half a year. In addition, a larger and tidy plot is required. This is difficult for most farmers to do due to the influence of capital and land topography.

At present, the most common greenhouse which is used most is a circular arc single-layer plastic film greenhouse with the span of 3-10 meters, which is also called a cold greenhouse. The plastic film of the greenhouse is attached to various supports to form a whole. The greenhouse is simple and easy to operate, can be large or small, can be long or short, is not influenced by the size of the terrain, and is short in manufacturing and building time and low in cost. Therefore, the greenhouse is the greenhouse which is most easily accepted by general farmers at present. However, because the single-layer plastic film structure is adopted, the wind resistance and heat preservation effects are not ideal; in addition, the framework of the greenhouse is troublesome to install, has longer span and exceeds the height of people, and has certain insecurity; the cost of the greenhouse framework exceeds 50 percent of the total cost; the framework material comprises bamboo, steel angle, round steel, steel pipe and the like, the steel framework is used, electric welding is often used, and substances such as welding slag, rust on the steel framework, paint and the like can pollute the land; in addition, in bad weather (strong wind, strong rain, snow, hail and the like), the greenhouse is easy to accumulate snow and water, the plastic film is damaged if the greenhouse is light, and the whole framework collapses if the greenhouse is heavy. Whether the bamboo and wood framework or the steel framework can cause fatal damage to crops in the greenhouse;

in order to improve the thermal insulation performance of the greenhouse, people continuously consider changing a single-layer plastic film of the greenhouse into a double-layer plastic film: a shed-in-shed with double-layer supports; the suspended ceiling and the like in the greenhouse increase the material quantity and the construction difficulty, reduce the space in the greenhouse and also have poor tightness, namely poor heat preservation. In addition, there are inflatable greenhouse designs, but the structure is not ideal and difficult to realize.

In summary, the single greenhouse widely used at present has the problems of low strength (wind resistance, snow resistance, rain resistance and hail resistance), safety in installation and use, relatively long installation time, more materials, more labor, high installation cost, soil pollution, and the most important problem that the sealing and heat preservation are not ideal. The warm shed covering the quilt has better heat preservation effect, but the construction cost and the construction period are really high, and the phenomena of land occupation and waste are more prominent.

In a word, at present, no plastic film greenhouse which has good heat insulation performance, high wind and rain resistance, is ideal and is suitable for vast low-income farmers exists.

Example two

In order to make the double-layer frameless inflatable closed heat-insulating plastic film greenhouse suitable for the requirements of different areas and different environments, particularly the requirements of poor areas, the second embodiment can be improved on the basis of the first embodiment as follows: namely, the inflatable main body and the underground parts at two sides are kept unchanged, and the color steel sandwich boards of the wall bodies (1) at two ends are changed into double-layer bubble films. Meanwhile, an exhaust fan (R), a steel wire rope (7) and the like are omitted, so that the cost of the greenhouse is lower, and the greenhouse is particularly suitable for being used in poor regions.
