Ventilated Solar Greenhouse

Abstract

The invention discloses a ventilation type sunlight greenhouse, which comprises a plurality of arc-shaped skeletons connected with one another through longitudinal structures, and a plastic film is spread on the arc-shaped skeletons, so that a greenhouse is formed; the roof and lower front part of the greenhouse are respectively provided with a plurality of ventilation openings and air inlets, V-shaped support structures are respectively and fixedly connected with the tops of the arc-shaped skeletons located at both ends of each ventilation opening in the greenhouse, and a V-shaped water-collecting plate is arranged between each two V-shaped support structures; a rainproof plate is hinged in each ventilation opening, and ventilation windows are hinged with the air inlets of the lower front part of the greenhouse. The ventilation type sunlight greenhouse has the following advantages: the wind load of the greenhouse cannot be increased additionally, the influence of wind power on the ventilation structure does not need to be taken into consideration, the service life is long, the natural ventilation principle of buildings can be utilized to realize natural ventilation, the structure is reasonable, the ventilation effect is good, and the manufacturing cost is low; the ventilation type sunlight greenhouse is convenient and quick to install, does not have installation and maintenance operation risk, and is highly safe; the ventilation type sunlight greenhouse can implement a wind-shielding and rainproof function, weather changes, such as rain and hail, do not need to be worried about for greenhouse ventilation, and the effective time of the natural ventilation regulation of the greenhouse environment is prolonged.

Description

technical field [0001] The invention relates to facility agriculture technology, in particular to a ventilated solar greenhouse. Background technique [0002] Greenhouses first appeared in the application of off-season crop production, mainly considering the problem of lighting and heat preservation in winter applications. Nowadays, most greenhouses are used in all-season production applications. The hot climate in summer and the ventilation adjustment ability of greenhouses with seasonal climate changes are particularly important. [0003] However, currently used greenhouses generally lack reasonable natural ventilation technology, especially solar greenhouses that use simple structures and film coverings. It is impossible to use high-cost ventilation technology. The air vents of the artificial membrane are used for natural ventilation. Such a backward form of ventilation is far from meeting the ventilation and regulation needs of the greenhouse environment in all seasons....

AI Technical Summary

Problems solved by technology

[0004] Natural ventilation technology has been used for a long time, and solar greenhouses have very suitable ambient temperature conditions for natural ventilation regulation. However, due to the large self-weight load and wind load of the conventional natural ventilation technology that protrudes from the roof, it has a great impact on the structural strength and cost of solar greenhouses. The impact is so great that this energy-saving ventilation method has not been effectively used in greenhouse applications
