Solar sail for solar greenhouse

Abstract

The invention discloses a solar sail for a solar greenhouse. The solar sail is characterized by comprising a frame, a condensing light reflecting cover plate or a light reflecting film, a greenhouse film, a heat-insulating quilt and a switch driver, the bottom end of the frame is hinged to a rear roof of the solar greenhouse, one end of the switch driver is fixedly connected with the top end of the frame while the other end of the same is hinged to the rear roof of the solar greenhouse, and the condensing light reflecting cover plate or the light reflecting film, the greenhouse film and the heat-insulating quilt are sequentially stacked on the frame and fixedly connected. The solar soil can be used for both newly built solar greenhouses and upgrading and rebuilding of old greenhouses. At present, more than 90% of greenhouses currently used in Northern cold regions need artificial energy-consuming temperature increase for fruit-vegetable production in winter, which is high in productioncost and generates a lot of emission causing environment pollution. If the solar sail is used to rebuild existing greenhouses, the rear roof of the greenhouse is light-permeable; if the solar sail and a heat collection and supply system thereof are additionally mounted, the defect that the old greenhouses are insufficient in heat storage can be made up.

Description

technical field [0001] The invention relates to agricultural facilities, in particular to solar greenhouse components, which is a solar sail for the solar greenhouse. Background technique [0002] As a technical equipment for facility agriculture, solar greenhouses are becoming more and more common in cold zone areas. However, traditional greenhouses have limited ability to absorb and store solar energy by themselves, and it is difficult to carry out winter production without artificial energy consumption, especially in high latitude areas. Most of the solar greenhouses built have given up winter production due to poor heat storage capacity, low night temperature, and increased costs due to manual energy consumption. Therefore, the economic benefit of facility agriculture in the north is poor, the enthusiasm of farmers for production is not high, and the industrial development is slow.

[0002] As a technical equipment for facility agriculture, solar greenhouses are becoming more and more common in cold zone areas. However, traditional greenhouses have limited ability to absorb and store solar energy, and it is difficult to produce in winter without artificial energy consumption, especially in high latitude areas. Most of the solar greenhouses built have given up winter production due to poor heat storage capacity, low night temperature, and increased costs due to manual energy consumption.

Therefore, the economic benefit of facility agriculture in the north is poor, the enthusiasm of farmers for production is not high, and the industrial development is slow
