Embodiment Construction

[0067] The technical solution of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0068] Such as Figure 1-15 As shown, a multi-span solar greenhouse for annual production in the Yangtze River Basin includes an arched circular greenhouse 1 and a solar greenhouse 2 and a workshop 3.

[0069] The arched circular greenhouse 1 and the solar greenhouse 2 are all arranged in a north-south direction, extending from east to west; the arched circular greenhouse 2 is located on the south side, with a span of 10.0m, a shoulder height of 3.0m, and a ridge height of 5.0m; the solar greenhouse 2 is located On the north side, the span is 10.0m, the front shoulder height is 3.0m, the ridge height is 5.5m, the rear wall height is 4.0m, the rear wall thickness is 0.60m, the rear roof inclination angle is 46°, and the rear half slope roof horizontal projection is 1.40 m; The working room 3 is close to the gable 24 at the east end of t...

Abstract

The invention discloses a multi-span solar greenhouse used for annual production in the Yangtze River basin region. The greenhouse comprises a circular-arch-shaped greenhouse body, a sunlight greenhouse body and a workshop. The circular-arch-shaped greenhouse body and the sunlight greenhouse body are connected side by side in the length direction and isolated from each other by a plastic thin film; an outer shading system is arranged above the circular-arch-shaped greenhouse body and the sunlight greenhouse body, a first inner heat preserving system is arranged in the circular-arch-shaped greenhouse body, and a second inner heat preserving system is arranged in the sunlight greenhouse body. Greenhouse framework structures are installed in an assembled mode, time and labor are saved, construction and maintenance are convenient, and the greenhouse can be transferred to a different place to be installed for repeated use. The greenhouse overcomes defects that common plastic greenhouses and dual-layer thin film greenhouses are poor in heat preservation and sunlight greenhouses are high in temperature and humidity in summer, a wall is good in heat preservation and heat storage property, solar energy is fully used, a rear wall can increase the light-permeating area, and light is fully used. The greenhouse is high in compatibility and suitable for regions to the south of the Huaihe River.

Description

Technical field [0001] The invention relates to a greenhouse structure, in particular to a multi-span solar greenhouse used for annual production in the Yangtze River Basin. Background technique [0002] my country's modern facility gardening is in the ascendant. As an energy-saving and low-cost facility, the solar greenhouse is in line with my country's current development needs. In the northern area bordered by the Qinling-Huaihe River, solar greenhouses have been widely promoted in this area due to the cold winter but sufficient sunlight. The southern region has less sunlight in winter and is not suitable for the construction of conventional solar greenhouses. Therefore, the horticultural facilities in this area are mostly plastic greenhouses. The solar greenhouse has the characteristics of heat storage during the day and heat preservation at night. Crops can be cultivated without heating in winter. However, the three sides of the greenhouse are walls. The ventilation and lig...
