Description

A photovoltaic power generation insulation greenhouse structure

technical field

The utility model relates to the technical field of planting greenhouses, in particular to a photovoltaic power generation heat preservation greenhouse structure. the

Background technique

Greenhouses are special equipment for vegetable production and are often used to grow off-season vegetables. With the development of production, greenhouses are more and more widely used. At present, greenhouses have been used for potted and cut flower cultivation. Fruit tree production is used for cultivating grapes, strawberries, watermelons, melons, and peaches. And citrus, etc., forestry production is used for tree seedling cultivation, ornamental tree cultivation, etc.; aquaculture is widely used for silkworm, chicken, cattle, pig, fish and fry; in 1958, China was able to produce agricultural products by itself. Polyethylene film, so the production of vegetables covered by small greenhouses has been extensive; in 1978, greenhouse production has been extended to all parts of the south, and the national greenhouse area has reached 100,000 mu. So far, the national greenhouse area has basically stabilized at more than 100,000 mu. Among them, there are more than 70,000 mu in the provinces and cities in the arid regions of northern China. It is estimated that the cultivation area of greenhouses will grow to about 200,000 mu during the "Seventh Five-Year Plan" period. the

At present, the material used to cover greenhouses is plastic film, which is suitable for covering large areas, because it is light in weight, has good light transmission and heat preservation performance, strong plasticity, low price, and is widely used. In the cold northeastern region, its winter temperature can reach minus 40 degrees. -50 degrees, the traditional film insulation effect is poor, resulting in a relatively low temperature in the greenhouse, which affects the growth of crops in the greenhouse. Power generation kills two birds with one stone and is environmentally friendly, but the traditional skeleton structure is made of bamboo and wood poles, cement poles, light steel pipes or pipes. On the one hand, due to the large area of greenhouses in northern China, more photovoltaic panels are used in the north. The weather in the north is harsh in winter, with heavy snowfall and long hours. The traditional structure has a small load capacity and is prone to collapse, causing unnecessary economic losses. At the same time, the traditional photovoltaic panels adopt a tiled structure, which affects the ability to receive sunlight and the tiled structure affects the direct sunlight entering the interior of the greenhouse and affects the photosynthesis of plants. the

Therefore, based on the above problems, the utility model provides a photovoltaic power generation heat preservation greenhouse structure. the
