A double-arch three-film greenhouse

technical field

The utility model relates to the technical field of solar greenhouses, in particular to a double-arch three-film greenhouse.

Background technique

my country is a vast country with a wide latitude spanning from north to south, and the amount of heat received by the sun varies from place to place. According to the difference in the accumulated temperature of each place, China has cold temperate, middle temperate, warm temperate, subtropical, and tropical temperatures from north to south. In the Qinghai-Tibet alpine zone, and in the special alpine region of Qinghai-Tibet, the thermal conditions vary greatly from place to place, and the agricultural development also varies greatly from place to place. In the winter in the northerly regions or in regions where it is relatively cold all year round, the planting industry is greatly limited due to climate reasons. With the continuous progress of the society, the traditional agricultural production mode can no longer meet the needs of the development of modern civilization. The new type of facility agriculture has gradually attracted people's attention and attention, the most representative of which is the greenhouse facility.

Greenhouses, also known as greenhouses, can transmit light and keep warm. They are used to cultivate plants. In seasons that are not suitable for plant growth, they can provide greenhouse growth periods and increase production. Seedling etc. There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions. Improving the thermal insulation performance of the greenhouse and reducing energy consumption are the most direct means to improve the production efficiency of the greenhouse. The thermal insulation ratio of the greenhouse is a basic indicator to measure the thermal insulation performance of the greenhouse. The greenhouse insulation ratio refers to the ratio of the coverage area of the greenhouse light-transmitting material with a small thermal resistance to the sum of the coverage area of the greenhouse enclosure structure with a large thermal resistance and the ground area. The larger the insulation ratio, the better the insulation performance of the greenhouse. In actual production, because producers do not pay attention to or blindly save costs and other reasons, greenhouses generally have the problem of poor thermal insulation effect, resulting in the greenhouse not achieving the expected production efficiency.

Therefore, how to solve the current situation of the poor thermal insulation effect of the greenhouse in the prior art is a problem to be solved urgently by those skilled in the art.
