[0024] like Figure 3 As shown: In a preferred embodiment, the outer wall 110 includes a main frame 111, an inner sealing plate 112, an insulation layer 113, a radiation shielding plate 114, an outer sealing plate 115, and a reinforcing keel 116. The inner sealing plate 112 is located on one side of the main frame 111, and the radiation shielding plate 114 is located on the other side of the main frame 111. The outer sealing plate 115 is located on the outer side of the radiation shielding plate 114.
