Sunlight greenhouse

Abstract

The invention discloses a sunlight greenhouse, which is enclosed by two side walls on east and west faces and a rear wall on the north side. A front slope surface and a rear slope surface are formed and are provided with a plurality of transverse or longitudinal bearing lines or bearing beams; transparent thermal insulation layers are laid on the bearing lines or bearing beams of the front slope surface; and transparent foam material layers are arranged on the bearing lines or bearing beams of the rear slope surface. The rear wall and the two side walls are hollow wall bodies, and bottled or bagged black water or water packaged by black bottles or black bags is arranged in the hollow wall bodies. By the sunlight greenhouse, the land utilization rate can be greatly improved; light can penetrate through the rear slope surface in the daytime, so that illumination of north plants in the greenhouse is improved; thermal insulation objects are needed to be covered on south and north sides inthe greenhouse at night in an inner thermal insulation mode or an outer thermal insulation mode; a curtain rolling machine, and thick and fine curtain rolling shafts which are arranged at intervals are arranged on a ridge part; and nighttime thermal insulation objects on the south side are rolled on the coarse section of an output shaft and nighttime thermal insulation objects on the north side are rolled on the fine section of the output shaft through ropes.

Description

technical field [0001] The invention relates to a solar greenhouse for growing agricultural products, in particular to an agricultural solar greenhouse with a back wall and a thermal insulation layer. Background technique [0002] In the current agricultural production of protected areas, the protection facilities with the largest area are solar greenhouses and large arch sheds. Solar greenhouses have the best protection conditions. In many areas in northern my country, agricultural production can be carried out on an annual basis, followed by large arch sheds, but it is difficult to carry out annual production. , especially in deep winter is difficult to produce. Compared with the two, the solar greenhouse has the following characteristics: 1. Good heat preservation and heat storage performance, but high construction and use costs; 2. The land utilization rate is low, only 45-55%; 3. It can only receive sunlight from the south, and the rest It is opaque on three sides. On ...

[0002] In the current agricultural production of protected areas, the protection facilities with the largest area are solar greenhouses and large arch sheds. Solar greenhouses have the best protection conditions. In many areas in northern my country, agricultural production can be carried out on an annual basis, followed by large arch sheds, but it is difficult to carry out annual production. , especially in deep winter it is difficult to produce

Compared with the two, the solar greenhouse has the following characteristics: 1. Good heat preservation and heat storage performance, but high construction and use costs; 2. The land utilization rate is low, only 45-55%; 3. It can only receive sunlight from the south, and the rest Opaque on three sides

The solar greenhouse is equipped with a back wall, which has a strong thermal insulation and heat storage capacity, so it can be produced on a yearly basis. Although the large arched shed has good lighting, it cannot keep thermal insulation and heat storage, so it cannot be produced on an annual basis.

[0006] At present, there are only a few greenhouses with long back slopes, but they are not transparent, so the north side of the greenhouse is dark and cannot carry out good production, and the land output per unit area is greatly affected.
