Description

[0002] Food is the basis of people's survival. In order to avoid famine caused by food shortage, the state or enterprises will store reserve grain to stabilize the market price when food production decreases, and can directly distribute the reserve grain to the people to help them overcome the food crisis. As an important transit and storage warehouse type in the food industry, grain flat warehouse has the advantages of large storage capacity, good heat insulation and moisture-proof performance, low cost, convenient management, flexible use, etc., and is widely used. With the proposal of energy conservation and emission reduction, solar photovoltaic new energy has made rapid progress in the field of grain flat warehouses.

[0003] The photovoltaic panels of grain warehouses in the existing technology usually adopt a three-point ground-type support structure (with supporting points on the ridge and the two end eaves walls). The weight of the photovoltaic panels and the supporting structure is partially or completely borne by the warehouse roof, resulting in a greater risk of bearing weight on the warehouse roof, which does not meet the requirements for high-standard grain warehouse construction. In addition, since a supporting point must be set in the middle of the supporting structure of the ground-type photovoltaic panels, the roof waterproofing layer needs to be partially destroyed, which makes the construction difficult and the installation cost high. Summary of the invention
