Winter vegetable sunlight greenhouse in alpine regions

Abstract

The invention discloses a winter vegetable sunlight greenhouse in alpine regions. The winter vegetable sunlight greenhouse comprises a cold-proof layer, a front wall, a daylighting roofing, a greenhouse top, a rear roofing, a cob wall, a biomass counter-burning multipass low-carbon and energy-saving hot water boiler, a hot water outlet pipe, a heat sink, a water return pipe, a chimney, a cotton quilt and an electric roller shutter machine, wherein the front wall is taken as a starting point; the corresponding roofing daylighting angles are 53 DEG -57 DEG, 48 DEG -52 DEG, 43 DEG -47 DEG, 38 DEG -42 DEG, 33 DEG -37 DEG, 28 DEG -32 DEG and 23 DEG -27 DEG respectively at the distances of 0.5 m -1.5m, 1.5 m -2.5m, 2.5 m -3.5m, 3.5 m -4.5m, 4.5 m -5.5m, 5.5 m -6.5m and 6.5 m -7.5m from the front wall; a distance from a perpendicular line of the greenhouse top to the interior of the cob wall is 0.5-1.5m; a height from the greenhouse top to an indoor ground plane is 4.4-4.6m; an elevation angle between a top part of the cob wall and the interior of the greenhouse roofing is 63 DEG -67 DEG; a base angle located in the greenhouse is 80 DEG -90 DEG; and the biomass counter-burning multipass low carbon and energy-saving hot water boiler is arranged in the greenhouse.

Description

technical field [0001] The invention relates to a sunlight greenhouse, in particular to a winter vegetable sunlight greenhouse in an alpine region. Background technique [0002] Sunlight greenhouses are agricultural planting facilities for growing vegetables in the cold season. Generally, vegetables are cultivated overwintering without heating. Under the condition of no heating, the source of temperature in the greenhouse mainly depends on the direct radiation and diffuse radiation of the sun, which shines through the film to the ground and Insulation walls, in turn, increase the indoor temperature, so the size of each part of the greenhouse must be designed according to the angle of altitude, latitude and sunlight, especially the size of the lighting surface angle of the greenhouse and the inward angle of the slope of the rear roof are important for the lighting, heat preservation and storage of the greenhouse Heat plays an important role. At present, the problem of heat pr...

Problems solved by technology

[0003] The present invention aims at the problems of the above-mentioned products, and provides a winter vegetable solar greenhouse in the alpine region, which solves the above-mentioned low temperature in winter in the northern frigid zone of my country, and the unreasonable design of the lighting roof angle and the inward elevation angle of the rear roof slope will lead to the lighting and heat preservation of the greenhouse. The capacity has certain limitations. At the same time, the traditional method of heating requires a large amount of fuel as an energy source, which not only increases the cost of heating equipment, but also produces a large amount of waste gas released by these energy sources during combustion. It will also cause environmental pollution and other problems.
