Description

Detachable solar greenhouse for winter and summer

technical field

The invention relates to a solar greenhouse, in particular to a dual-purpose detachable solar greenhouse for winter and summer.

Background technique

In recent years, a variety of different types of solar greenhouses have emerged in northern my country. The back walls of these solar greenhouses are mostly brick, concrete or earth-hit wall structures, and the front roof arches are often made of bamboo wood or hot-dip galvanized steel pipes. , the buffer room is located outside the side wall of the greenhouse. It uses the principle of heat storage during the day and heat release at night. Compared with other non-heating agricultural facilities, the thermal insulation performance is better, and it can realize the delayed autumn, overwintering and early spring production of crops. It has become the "Three North "The most common type of horticultural facilities in the region. However, my country has a vast territory, diverse climatic conditions, and large temperature differences between seasons. Some solar greenhouses with good thermal insulation performance have poor indoor natural ventilation in summer, and the temperature is often too high, making it difficult to carry out summer production. Some users often expose the film to open field production or abandon indoor land in summer, resulting in a decline in economic benefits and land utilization. In addition, the arches on the front roof of the existing solar greenhouses are mostly fixed structures, which require a long time for on-site construction, great difficulty in construction, complicated maintenance processes, and cannot be relocated and installed in other places for reuse. The buffer room is located on the outside of the gable of the solar greenhouse, with limited length and narrow space, where sundries or tools cannot be piled up, and workers cannot be accommodated.
