Chinese solar double arch greenhouse

The greenhouse is a double arch structure, the outer layer is covered with film, and the inner layer is covered with film thermal insulation quilt. 

When the quilt is rolled up, the indoor light increases, the side ventilation promotes the internal air circulation of the greenhouse, and the insect protection net prevents the entry of pests. 

When it is cold, put down the quilt to create a double-layer insulation effect. 

Design principle: To prevent excessive rain and snow, resulting in quilt can not roll up the situation. 

The outer layer can be fitted with a snow shaker to shake off accumulated snow.
