Underwater base plate sledge

The utility model relates to the technical field of ocean engineering, and discloses an underwater base plate sledge. The base plate sledge comprises a base (1) and a reinforcing plate assembly (4) used for fixing a manifold (3), and the reinforcing plate assembly (4) is arranged on the base (1). The base (1) comprises a bottom plate (8), at least two cross beams (7-1) and at least two longitudinal beams (7-2), the cross beams (7-1) and the longitudinal beams (7-2) are fixed on the bottom plate (8), the cross beams and the longitudinal beams are arranged in a crossed mode, and an exhaust pipe (6) is arranged on the bottom plate (8) corresponding to a crossed face formed by two adjacent cross beams and two adjacent longitudinal beams in a crossed mode. According to the utility model, the base and the reinforcing plate assembly are matched for use, so that the manifold can be quickly disassembled and assembled, and the anti-sliding capability of the underwater base plate sledge is improved.
