Double-layer thermal insulation solar greenhouse

Abstract

The invention discloses a double-layer thermal insulation solar greenhouse. The double-layer thermal insulation solar greenhouse comprises two parts, namely, a thermal storage and insulation wall bodyand a greenhouse framework, the thermal storage and insulation wall body is in the east-west direction in structure, the east-west length is 90 m, the south-north span is 8.5 m, a west side wall andan east side wall form the thermal storage and insulation wall body, an outer-layer shed and an inner-layer shed are arranged between the west side wall and the east side wall, the outer-layer shed comprises an outer arch frame, the outer side of the outer arch frame is covered with an outer covering film, a plurality of outer arch pull rods are arranged on the inner side of the outer arch frame,the inner-layer shed comprises an inner arch frame, the outer side of the inner arch frame is covered with an inner covering film, a plurality of inner arch pull rods are arranged on the inner side ofthe inner arch frame, multiple spraying systems are further arranged on the inner side of the inner arch frame and are connected to liquid conveying pipes, an inner-layer thermal insulation quilt isarranged at the high point between the outer arch frame and the inner arch frame and is wound around a reel, one end of the reel is movably connected to a left wall body, the other end of the reel isconnected to a roller shutter motor fixed to a right wall body, and the inner-layer thermal insulation quilt ascends and descends in a rotating mode through the roller shutter motor and a pull rope.

Description

technical field [0001] The invention belongs to the field of agricultural equipment, and in particular relates to a double-layer thermal insulation solar greenhouse. Background technique [0002] The solar greenhouse is a greenhouse structure independently developed by my country. It has the characteristics of low construction cost and good energy-saving effect. [0003] 25%, in the context of rising petrochemical energy prices and increasingly stringent environmental protection, solar greenhouses have become an important means for my country's facility horticulture industry to break through resource bottlenecks and maintain long-term effective supply of winter agricultural products. With the vigorous promotion and popularization of vegetable basket projects in various places , the construction of solar greenhouses will reach an unprecedented scale. [0004] However, the main problem of solar greenhouses in my country at present is that ① the performance of heat storage an...

Problems solved by technology

[0004] However, the main problem of solar greenhouses in my country at present is that ① the performance of heat storage and heat preservation in winter needs to be improved

The thermal insulation quilt or straw curtain is directly covered on the shed film by the roll-laying mechanism. Since the overlapping of the thermal insulation quilt is mostly tied with a tether, it is easy to have a lax lap; in addition, the thermal insulation quilt is mostly made of felt or light foaming material At night, strong winds can easily blow up the thermal insulation quilt covered on the canopy film, causing more heat loss in the room and reducing the thermal insulation effect of the thermal insulation quilt.

②Existing solar greenhouses are mainly used for winter production. Since they do not have facilities such as shading and cooling, oversummer cultivation of crops that are not resistant to high temperatures has become a problem for farmers. During the high temperature season from July to August, they can only "suspend the shed" and use it efficiently Anniversary or long-season production in solar greenhouses has become an urgent problem to be solved

③Most of the vents on the roof of the existing solar greenhouse are manual seams, which cannot be used in windy and rainy weather; in winter, they are mostly covered by insulation quilts or straw curtains, and are inconvenient to use when dehumidification and ventilation are required, and need to be improved
