A greenhouse device includes a main frame and two shielding assemblies arranged on the top side of the main frame, the shielding assembly includes an arch roof frame and two shielding units, the arch roof frame has a central peak part and two bottoms on both sides, the two shielding units are respectively arranged on both sides of the central peak part of the arch roof frame.Each shielding unit includes a scroll, two driving support mechanisms and a shielding layer.The scroll is arranged above the arched roof frame.The two driving support mechanisms jointly support the winding shaft and can drive the winding shaft to rotate around its shaft to move between the central peak part of the arch roof frame and one of the corresponding bottom edges.The two driving supporting mechanisms drive the winding shaft to move back and forth between the central peak part of the arch roof frame and one of the corresponding bottom edges to control the winding or unfolding of the shelter layer.一種溫室裝置，包含一主架及兩設置在該主架的頂側的遮蔽總成，該遮蔽總成包括一拱形頂架及兩個遮蔽單元，該拱形頂架具有一中央峰部及分別位於兩側的兩個底邊，該兩遮蔽單元分別設置於該拱形頂架的中央峰部的兩側。每一遮蔽單元包括一捲軸、兩個驅動支撐機構及一遮蔽層。該捲軸設於該拱形頂架上方。該兩驅動支撐機構共同支撐該捲軸並可驅動該捲軸繞其軸轉動地在該拱形頂架的中央峰部與對應的其中一底邊之間移動。藉由該兩驅動支撐機構驅動該捲軸在該拱形頂架的中央峰部與對應的其中一底邊之間往復移動而控制該遮蔽層捲收或展開。
