Automatic linkage-type simple rain protection shed

The invention provides an automatic linkage-type simple rain protection shed. A hot-dip galvanized steel skeleton structure is adopted for the rain protection shed. A circular-arch-type roof is adopted. The length of the rain protection shed is 24 meters in the north and south direction. A span is formed every eight meters, and a total of three spans are formed. The width of the rain protection shed is 28 meters in the east and west direction, a bay is formed every four meters, and a total of seven bays are formed. The foundation elevation is +/-0.000, the height of each upright is 3 meters, the arch rise is 2 meters, and the total height is 5.0 meters. Rain protection shed skeletons are of a hot-dip galvanized steel structure, 15-filament thin films are adopted for covering a roof part and the periphery, and clamping rings and clamping grooves are specially adopted for fixing the rain protection shed. The problem that on a rain day, supporting rods are very prone to rusting after wet, and therefore the supporting rods are ineffective in supporting is avoided. Meanwhile, maintenance cost is saved for a farmer, and production cost of the farmer is reduced. The automatic linkage-type simple rain protection shed is good in wind resistance performance and compression resistance performance.
