1. An emergency response containment vessel (ERCV) comprising:
a vehicle frame including a frame body, and a plurality of wheels rotatably connected to said frame body; and
a sealing container fixedly mounted on said frame body, being carried by said vehicle frame, and including
a barrel body extending along a central axis, defining a receiving space adapted for receiving a cylinder therein, and including an open end that defines an opening in spatial communication with said receiving space and that has an outer rim,
a locking module including
a fixed seat that is connected to said barrel body and that is disposed adjacent to said open end,
a ring seat that is connected rotatably to said fixed seat, that is rotatable relative to said fixed seat about the central axis, and that includes an annular bottom wall extending radially and outwardly from said outer rim, an annular side wall connected to and perpendicular to a periphery of said annular bottom wall and extending away from said barrel body in a direction along the central axis, and a plurality of blocks projecting radially and inwardly from an inner surface of said side wall and spaced apart from one another along a circumferential direction of said side wall, said annular bottom wall, said annular side wall and said blocks cooperating with one another to define an annular groove thereamong, said ring seat having a plurality of notches each between adjacent two of said blocks and in spatial communication with said annular groove, and
a driving device that is operable to drive said ring seat to rotate, and
a cover module including a connecting arm that is pivotably connected to said fixed seat, and a cover that is connected to said connecting arm, that removably covers said opening, and that includes
a central portion removably covering said opening, and
a plurality of engaging portions projecting radially and outwardly from a periphery of said central portion, being respectively complementary in shape with said notches, and removably received in said annular groove,
wherein said ring seat is driven by said driving device to rotate relative to said fixed seat between an unlock position, where said engaging portions are aligned respectively with said notches so as to allow said engaging portions to pass respectively through said notches so that said cover is removable from a position of covering said opening, and a lock position, where said engaging portions are misaligned with said notches and are blocked respectively by said blocks to restrict said cover at the position of covering said opening.
