Description

Technical Field

[0001] The invention relates to the technical field of greenhouses, and in particular to a double-opening butterfly-type skylight plastic greenhouse for large-scale vegetable production. Background Art

[0002] At present, the most widely used in vegetable facility production are relatively economical and affordable various steel frame plastic greenhouses. During the growth of vegetable facilities, ventilation is needed to adjust the temperature and humidity in the facility, exchange gases, and ensure the healthy growth of plants. At present, plastic greenhouses are ventilated through arch side windows, arch bottom side windows and shed doors at both ends;

[0003] Among them, arched bottom side windows are the most commonly used. They use roller shutter rods and motors to control the window size, which is simple and easy. However, bottom ventilation can only solve horizontal ventilation and cannot form vertical convection to discharge water vapor that rises to the upper part of the shed due to instantaneous high temperature. The humid hot air will also produce a large amount of condensed water on the roof and then drip on the leaves or stems of plants, causing a variety of diseases, increasing the cost of disease prevention and control and food safety risks;

[0004] At present, double-opening butterfly skylights have begun to be installed on the top of high-end glass greenhouses. The transmission rod is driven by an electric motor, which in turn drives the rack to extend and retract to complete the opening and closing of the top window. The double-opening butterfly skylight has a large ventilation area, and the degree of opening and closing can be flexibly controlled by temperature and humidity sensors. The ventilation effect is good, but the skylight control components (rack + rack box) are too expensive, so they have not yet been widely used in vegetable facility production.

[0005] The top skylight of the existing plastic greenhouse is inconvenient to operate and control. The plastic greenhouse film is prone to expansion, relaxation and aging after being exposed to high temperatures in the sun, and is easily blown away by strong winds, causing losses. Advanced skylights cannot be used in plastic greenhouses for vegetable production due to their high cost. Summary of the invention

[0006] To this end, the present invention provides a double-opening butterfly skylight plastic greenhouse for large-scale vegetable production, aiming to solve the problem that the top skylight of the existing plastic greenhouse is inconvenient to operate and control, the plastic greenhouse film is prone to expansion, relaxation and aging after being exposed to high temperatures in the sun, and is easily blown away by strong winds, causing losses, while advanced skylights cannot be used in plastic greenhouses for vegetable production due to their high cost.
