One-wall energy-saving sunlight greenhouse

Abstract

The invention discloses a one-wall energy-saving sunlight greenhouse which is characterized in that both gable walls are light-transmission gable walls which are internal and external light-transmission layers composed of light-transmission films and support grids; the grids between the internal light-transmission layers and external light-transmission layers are connected and fixed with a framework by lacing bars; a reservoir is arranged at the bottom of a rear wall; a thermal storage tube nest communicated with the reservoir to form a circulation loop is arranged below a rear slope above the rear wall; and a reflective film is placed between the rear slope and the thermal storage tube nest. In the greenhouse, the light-transmission gable walls replace the original cob walls or brick walls; shading of the gable walls is avoided; the land utilization rate is increased; photosynthesis of plants is improved, so that output of planted crops can be significantly increased; compared with the existing greenhouse, the temperature is increased by 3-5 DEG C, and the benefit is increased by more than 10%; with the adoption of an arc greenhouse body, the highest point moves forward, and the best lighting angle is increased by 5-10 DEG; with the adoption of 1 million mu greenhouse, the greenhouse land area available is increased by 95.95 thousand mu, and the greenhouse utilization rate of the original 1 mu of land is as high as 109.59%; and the greenhouse is good in heat preservation, is windproof and rain-proof, and is high in stability.

Description

technical field [0001] The invention relates to facilities for agricultural planting, in particular to a one-wall energy-saving solar greenhouse in which two gable walls are all designed as light-transmitting gable walls. Background technique [0002] Due to the high energy consumption and high maintenance costs of modern multi-span greenhouses, it is difficult for general factories to make profits, which is contrary to energy conservation and emission reduction. Currently, vegetables and fruits produced in winter are produced by single-span solar greenhouses. The existing single solar greenhouse is composed of a back wall, two gables and a light-transmitting front roof. The existing solar greenhouse is usually composed of a back wall, two gables and a light-transmitting shed surface. The gable is made of earth or brick walls. The biggest disadvantage of this greenhouse structure is shading. For example, an 8-meter-wide solar greenhouse has a 45° triangular shading area at 9...

AI Technical Summary

Problems solved by technology

Because the shading of the gable material first affects the photosynthesis of plants, the ground temperature in the unlit part is low, so the output on both sides of the greenhouse is low, and the benefit is poor; at the same time, the greenhouse space is small, the lighting angle design is unreasonable, the height-span ratio of the greenhouse is small, and the light intensity Not enough; due to the high back wall and short back slope, it is generally difficult to plant tall plants in the front row space at about 1.5-2.0 meters; at the same time, the high back wall and short back slope plus the height of straw curtains and insulation quilts are used. When building a group of greenhouses, the distance between the front and rear greenhouses is very large (shade part), and the land utilization rate is low
