The invention discloses a multi-beam flow guide device for a moon pool structure scientific investigation ship, and relates to the field of ships. In the sailing process of a ship, a large number of bubbles can be generated near the water plane of a bow by broken waves, splashes and the like, and if the bubbles are discharged near the bottom of multiple beams at the bottom of the ship along with water flow, the measurement accuracy of the multiple beams can be greatly and negatively influenced. The device comprises a wave pressing plate, a wave reducing ring and a flow guide structure, the wave pressing plate is arranged on the lower portion of a moon pool, a gap is formed between the periphery of the wave pressing plate and the side wall of the moon pool, and the wave reducing ring is arranged at the lower end of the moon pool; the inner diameter of the upper end of the wave reducing ring is the same as that of the lower port of the moon pool, and the inner diameter of the wave reducing ring increases in an arc shape from top to bottom. The flow guide structure comprises a bottom plate arranged at the lower end of the wave reducing ring, wave reduction holes are formed in the bottom plate, the peripheries of the wave reduction holes are fixedly connected with a ring opening in the lower end of the wave reducing ring, and the bottom plate is connected with the bottom of a hullthrough rib plates. The device can effectively reduce the fluctuation of water flow entering the bottom of the ship, and the measurement precision of the multi-beam instrument is improved.
本发明公开了一种用于月池结构科考船的多波束导流装置,涉及船舶领域。船舶在航行过程中,碎波、飞溅等在船首水线面附近会产生大量的气泡,如果气泡随水流下泄到船底多波束底部附近,就会对多波束的测量精度产生极大负面影响。本发明包括压波板、降波环和导流结构,压波板设于月池下部,压波板外周与月池侧壁之间设有间隙,降波环设于月池下端端部,降波环的上端内侧口径与月池下端口径相同,降波环的从上往下其内径呈弧形增大,导流结构包括设于降波环下端的底板,底板上设有降波孔,降波孔的孔周与降波环下端的环口连接固定,底板与船体的底部通过肋板连接。该装置能够有效的降低进入船底的水流的波动,增加多波束仪器的测量精度。
