Pneumatically-controlled greenhouse capable of compressing air and forming convective cooling

Abstract

The invention belongs to a pneumatically-controlled greenhouse capable of compressing air and forming convective cooling. The greenhouse is characterized in that the greenhouse is of a metal herringbone framework structure, wherein PC transparent sunshine plates are paved on the front side and the back side of a metal herringbone framework; PC transparent sunshine plate movable windows are formedin the PC transparent sunshine plates and are welded with a cylinder I, a cylinder II and a cylinder III respectively; a fixed tempered glass window and a movable tempered glass window are formed in each of two sides of the herringbone top of the greenhouse; each movable tempered glass window is welded with a cylinder IV and a cylinder V; a compressed air source is supplied to each movable tempered glass window by an electric air pump; a wireless controller is used for controlling a three-way bypass electronic master air valve. The pneumatically-controlled greenhouse has the advantages that the PC transparent sunshine plate movable windows are formed in both the front side and the back side of the greenhouse, air convection movable windows are formed in the tops of the PC transparent sunshine plate movable windows, the automatic control is achieved through telescopic movement of cylinder rods, and the convective cooling is formed in the greenhouse and is used for controlling the temperature in the greenhouse.

Description

technical field

[0001] The invention relates to an agricultural technical facility, in particular to an air-compressed convective cooling pneumatic control greenhouse. Background technique

[0002] In summer, for farmers who plant greenhouse crops, the ventilation of the greenhouse can be said to be indispensable. The purpose is mainly to remove the waste heat and moisture in the greenhouse, adjust the air composition in the greenhouse, and eliminate harmful gases. Environmental temperature, humidity and air conditions are suitable for plant growth. At present, there are two types of cooling methods for greenhouses: mechanical fan ventilation and wet curtain fan cooling. Mechanical fan ventilation for greenhouses requires high-power fans and dual forced ventilation of intake and exhaust. If the greenhouse area increases, the ventilation effect will weaken, and the cost of the window opening mechanism and operating energy consumption will also increase. The cooling of the we...
