Inflatable thermal insulation system and multi-span greenhouse including the same

A greenhouse for preserving heat and reducing heat dissipation, the greenhouse comprising:

• a lateral frame having opposed ends;
• a vertical frame having a top side and a bottom side;
• a top cover;
• an inflatable and thermal insulation system including a thermal insulation quilt;
• a plurality of rotary shafts;
• and
• a plurality of flexible mounting slots,
• wherein the lateral frame is arranged above and supported by the vertical frame, the top cover is arranged above the lateral frame;
• wherein the plurality of rotary shafts are provided at both ends of the lateral frame, and at the top end of the vertical frame, wherein the plurality of rotary shafts are driven by a motor to rotate so that the thermal insulation quit moves,
• wherein the inflatable and thermal insulation system further includes an air compressor, a dust collector, a dehydrator, a dryer, a constant-pressure and air-releasing controller, and the thermal insulation quilt, which are communicated with each other through a pipeline,
• wherein the plurality of flexible mounting slots are at an outer surface of the thermal insulation quit and are used to seal top, bottom, left and right sides of the thermal insulation quilt,
• wherein the thermal insulation quilt has an inner portion with a honeycomb structure or a grid structure, and
• in a sunny day, the rotary shafts move the thermal insulation quilt in the lateral frame to one end, and move the thermal insulation quilt in the vertical frame to the top side and in a cloudy day or at night, the rotary shafts move the thermal insulation quilt to an opposite end, and the air compressor starts working to inflate the thermal insulation quilt.
