A double-layer enclosed vegetable greenhouse

Abstract

The invention discloses a double-layer closed vegetable greenhouse. The greenhouse comprises two rows of support columns vertically installed and an arc ceiling which is installed at the upper ends of the support columns and connects the two rows of support columns as a whole; water storage plates extending towards the outer side are further installed at the outer sides of the support columns; a water fender is further installed at the end of each water storage plate; the arc ceiling and the support columns at the two sides are wrapped and sealed by laminating; each water storage plate at the two sides is further provided with a slide rail; an arc sealing cover is further arranged on the arc ceiling. In the double-layer closed vegetable greenhouse, the water storage plates extending toward the outer side are arranged at the outer sides of the support columns and have three functions, wherein firstly, a broad installing space for installing the disposable arc sealing cover exists, secondly, the water storage plates can be used for storing clean rainwater for sprinkling and watering, and finally, the water storage plates can be used for installing a disposable vertical sealing cover.

Description

technical field [0001] The invention relates to a vegetable planting greenhouse, in particular to a double-layer closed vegetable greenhouse. Background technique [0002] The water irrigation of the existing vegetable greenhouses has always been a problem. The most commonly used method is to pump groundwater or river water for irrigation and spraying, which costs a lot for irrigation; and most of the existing methods are to pump river water. irrigation, but the pollution of the river water in the existing environment is relatively large, which is easy to cause pollution to the grown vegetables; and in winter, the heat preservation of the vegetable greenhouses is also a problem, and the existing planting greenhouses are mostly single-layer structures. , to keep the room temperature in the shed constant, the thermal insulation and heating device needs to run continuously, which requires huge energy consumption and increased costs; moreover, the ventilation of the existing gre...

[0002] The water irrigation of the existing vegetable greenhouses has always been a problem. The most commonly used method is to pump groundwater or river water for irrigation and spraying, which costs a lot for irrigation; and most of the existing methods are to pump river water. irrigation, but the pollution of the river water in the existing environment is relatively large, which is easy to cause pollution to the grown vegetables; and in winter, the heat preservation of the vegetable greenhouses is also a problem, and the existing planting greenhouses are mostly single-layer structures. , to keep the room temperature in the shed constant, the thermal insulation and heating device needs to run continuously, which requires huge energy consumption and increased costs; moreover, the ventilation of the existing greenhouses is mostly to roll up the film for ventilation, although the ventilation and ventilation The quality of the air is high, but the operation is more troublesome. It is inconvenient to operate all the covering films on the roof and supporting parts.
