    • A unit for protecting a propeller of a boat from underwater hazards like shoals, reefs and algae. The unit comprises a frame (10) which may have a floating structure, a supporting arrangement (14) for holding the propeller (8) below a bottom line of the floating frame, a mounting assembly (16) for pivotally attaching the floating frame (10) behind the boat (6) with a pivot axis (18) transverse to the boat (6), and a protective fin assembly (22) downwardly projecting from the frame (10) in front of and under the propeller (8). The protective fin assembly (22) has a transverse cutting blade (24) extending near the propeller. A spring arrangement (46) can be provided between the boat (6) and the floating frame (10) for exerting a pressure against pivotal motion of the floating frame (10) with respect to the boat (6).
    • 用于保护船只螺旋桨免受水下危害的单位,如浅滩,礁石和藻类。 该单元包括可以具有浮动结构的框架(10),用于将螺旋桨(8)保持在浮动框架的底线下方的支撑装置(14),用于枢转地附接浮动框架的安装组件(16) 10)在具有横向于所述船(6)的枢转轴线(18)的船尾(6)之后,以及保护翼组件(22),其在所述螺旋桨(8)的前方和下方从所述框架(10)向下突出。 保护翅片组件(22)具有在螺旋桨附近延伸的横向切割刀片(24)。 可以在船(6)和浮动框架(10)之间设置弹簧装置(46),以施加压力抵抗浮动框架(10)相对于船(6)的枢转运动。

    • PURPOSE:To prevent a propeller driving mechanism from damage even if driftwood or the like collides with a propeller machine, by constituting the bottom front edge of a propeller machine casing with an elastic material. CONSTITUTION:A propeller machine 18 is vertically and laterally turnably mounted to a transom 12 of a ship body 10. A propeller driving mecahnism consisting of a gear mechanism 40 is provided to the inside of a bottom casing 36 of the propeller machine 18. A front edge of the casing 36 is constituted by an elastic material 38 of rubber or the like. In this way, even if driftwood or the like moved along a ship bottom collides against the propeller machine 18, the driving mechanism is never damaged.
    • 目的:为了防止螺旋桨驱动机构即使漂流木等与螺旋桨机碰撞,也可以通过用弹性材料构成螺旋桨机壳的底部前缘。 构成:螺旋桨机18被竖直和横向可转动地安装在船体10的横梁12上。由螺旋桨机构40组成的螺旋桨驱动装置设置在螺旋桨机18的底部壳体36的内部。前部 壳体36的边缘由橡胶等的弹性材料38构成。 以这种方式,即使沿着船底移动的漂流木等与螺旋桨机18碰撞,也不会损坏驱动机构。
