The invention relates to a liquefied natural gas (LNG) leakage receiving device of a bottom support of a type-B enclosure system. The receiving device is of a rhombic basin-shaped structure composed of main screens and oblique plates, wherein the main screens and the oblique plates are formed by bending stainless steel plates. Stainless steel strip-shaped plates distributed in a crossed mode are arranged on diagonal lines of the rhombic basin-shaped structure. The rhombic basin-shaped structure is arranged between an outer bottom plate and the bottom support. The bottom support comprises laminated wood and an insulating layer. The rhombic basin-shaped structure is tightly wrapped with the insulating layer. The outer ends of the main screens are distributed at the outer ends of wrist plates. The outer ends of the wrist plates are wrapped with the main screens. The upper end faces of the oblique plates communicate with flat straight screened films in a support-free area. Gaps are reversed between the flat strai
