The invention relates to a moon pool drag reduction device which comprises a bottom plate which is shaped like an opening of a moon pool, and the bottom plate can be placed on a platform which is arranged at the bottom of the moon pool in a matched mode and protrudes inwards. Notches for communicating water bodies above and below the bottom plate through pipes are symmetrically formed in the periphery of the bottom plate; at least one pressure balance hole device is arranged in the middle of the bottom plate and comprises a through hole formed in the bottom plate, a pressure balance hole flowguide plate with the front portion tilting upwards is arranged above the through hole, and a pressure balance hole is formed between the front portion of the pressure balance hole flow guide plate andthe bottom plate. The design that the non-watertight open type steel plate girder structure cover plate is matched with the manual clamping device is adopted, the structure is simple, the design is ingenious, implementation is convenient, and the cost is low; devices such as a hydraulic oil cylinder and a control system are not adopted so that the construction cost and the later maintenance costare greatly saved.

    本发明涉及一种月池减阻装置,包括一与月池开孔仿形的底板,底板可搁置在月池底部配套设置的向内侧凸起的平台上;底板的周围设有对称布置的用以使底板上下方水体管通的缺口;底板中部设有至少一压力平衡孔装置,压力平衡孔装置包括开设于底板上的通孔,通孔上方设有一前部向上翘起的压力平衡孔导流板,压力平衡孔导流板前部与底板之间形成一压力平衡孔。本发明采用非水密的开放式钢制板梁结构盖板配合手动夹紧装置的设计,结构简单,设计巧妙,实施方便,成本低廉;不采用液压油缸和控制系统等装置,极大的节省建造成本和后期维护维修成本。
