The invention discloses a combined submarine driving device for inhibiting clearance leakage, which comprises a pump shell, a blade and a pump inlet, a circle of blade front cover plate is arranged on the periphery of the blade, the blade front cover plate is fixedly connected with the periphery of the blade, no clearance exists between the blade front cover plate and the blade, and the blade front cover plate rotates together with the blade; a gap is formed between the blade front cover plate and the pump shell in the radial direction, and a leakage flow channel is formed in the gap. A plurality of outer magnet assemblies are evenly arranged on the pump shell in the flowing direction of the leakage flow channel, a plurality of inner magnet assemblies are evenly arranged on the blade front cover plate in the flowing direction of the leakage flow channel, and the outer magnet assemblies and the inner magnet assemblies correspond to each other in position and are opposite in polarity, so that magnetic induction lines are generated. The front cover plate is additionally arranged on the impeller part, a magnetic structure is additionally arranged, the leakage flow of the submarine driving device is restrained according to the electromagnetic induction principle, the leakage amount and noise are reduced, and the efficiency and concealment of the submarine driving device are improved.

    本发明公开了一种组合式抑制间隙泄露的潜艇驱动装置,包括泵壳、叶片和泵进口,在叶片外围设有一圈叶片前盖板,叶片前盖板与叶片外围固定连接且两者之间无间隙,叶片前盖板随叶片共同旋转;叶片前盖板与泵壳在径向上具有间隙,间隙处形成泄露流道;泵壳上沿泄露流道的流动方向均匀布置有多组外磁铁组件,叶片前盖板上沿泄露流道的流动方向均匀布置有多组内磁铁组件,外磁铁组件和内磁铁组件的位置相对应且极性相反,从而产生磁感应线。本发明通过对叶轮部件进行增加前盖板改造和增加磁性结构,利用电磁感应原理对潜艇驱动装置的泄露流进行抑制,减少泄露量和噪音,提高潜艇驱动装置的效率和隐蔽性。
