The present invention relates to a supply supporting apparatus for smoothly supplying liquefied natural gas (LNG) to a submerged pump (3) connected to a pump tower installed in a cargo tank. The supply supporting apparatus includes a housing (10) and a reverse flow prevention apparatus (20). The housing (10) has a hexagonal structure which has an opening (12) formed on the upper part to have the lower part of the submerged pump (3) being inserted and mounted therein while having a storage space (14) arranged therein in a predetermined size. The housing (10) also includes: an extended hole (16) formed in a predetermined size on each corner part of the lower surface; and an adhesion surface (18) formed to be stepped in a longitudinal direction along the left and right upper parts of the extended hole (16). The reverse flow prevention apparatus (20) includes: a pair of left and right coupling pieces (22) which are formed on the lower inner surfaces of upper storage spaces adjacent to each extended hole (16) while being spaced apart from each other by a predetermined gap; an operating bar (24) which has a side part coupled to each of the coupling pieces (22) and the other end moving in a hinged manner around the coupling pieces (22) that are extended and protrude into the storage space (14); an operating rod (26) having both ends coupled to the operating bar (24); and an opening and closing plate (28) which opens or closes the extended hole (16) while having left and right corners adhered to or separated from the adhesion surface (18) by using the weight of the operating rod (26) while being coupled to the lower surface of the operating rod (26) in a longitudinal direction and having a predetermined width.

    본 발명은, 카고탱크 내부에 설치되는 펌프타워와 연결되는 잠수펌프(3)에 엘엔지가 원활하게 공급하는 공급보조장치로서, 상측에는 잠수펌프(3)의 하측 부위가 삽입되어 장착되도록 개구부(12)가 형성되고 내부에는 일정크기의 저장공간(14)이 마련되는 육면체 구조로 이루어지되, 하면의 각 모서리 부위를 따라 일정 길이로 형성되는 장공(16)과, 장공(16)의 좌우 상측 부위를 따라 길이 방향으로 단차져 형성되는 밀착면(18)이 형성되는 하우징(10); 각 장공(16)과 인접한 상부저장공간(12)의 하측 내면 각각에는 일정 간격 이격되어 좌우 한 쌍으로 설치되는 결합편(22)과, 일측 부위는 각 결합편(22)에 결합되고 연장되는 타측 부위는 저장공간(14) 내부로 돌출되는 결합편(22)을 기점으로 힌지 운동하는 가동바(24)와, 양단 부위가 가동바(24)에 결합되는 가동봉(26)과, 일정 폭을 가지며 가동봉(26) 하면에 길이 방향으로 결합되되 가동봉(26)의 자중에 따라 좌우 모서리 부위가 밀착면(18)과 밀착되거나 분리되면서 장공(16)을 개폐하는 개폐판(28)으로 이루어지는 역류방지기구(20);를 포함하는 카고탱크에 설치되는 엘엔지 공급보조장치를 제공한다.
