    • A method for the maintenance of a ship or platform propulsion assembly includes providing a hull insert forming a watertight housing located within a hull of a ship except for an opening. A motor is in the hull external to the housing and a thruster is external to the hull. A telescopic driving shaft sealingly passes through one of the walls of the housing to operatively connect the motor and the thruster to transmit movement to the thruster. Moving the thruster includes retracting the thruster into the housing through the opening. A separable submersible movable hatch is lowered by removable hanging cables. The submersible movable hatch externally engages the housing and sealingly closes the opening to close the housing and form a watertight closed chamber. Fluids within the closed chamber are evacuated even when the hull is floating and partially submersed, with the thruster at least partially in air.
    • 一种用于维护船舶或平台推进组件的方法包括提供形成位于船舶船体外的除了开口之外的水密壳体的船体插入件。 电机在外壳外部,推进器位于船体的外部。 伸缩驱动轴密封地穿过壳体的一个壁,以可操作地连接马达和推进器,以将运动传递到推进器。 移动推进器包括通过开口将推进器缩回到壳体中。 可拆卸的潜水可移动舱口由可拆卸悬挂电缆降低。 潜水移动舱口外部接合壳体并密封地关闭开口以关闭壳体并形成水密闭合的室。 即使在船体浮起并部分浸没的情况下,封闭室内的液体也被排空,推进器至少部分地在空气中。

    • The present invention relates to a portable boat with catamaran configuration. The boat basically consists of two inflatable floats joined by two connecting bars with plates at their ends for fastening the connecting bars to the floats. A rigid platform can be assembled between the two connecting bars, forming a deck for the occupant. The present invention allows the occupant to remain standing on the rigid platform while using a paddle to propel the boat. The lateral floats provide greater stability, making it easier for the occupant to keep his balance. Removable fins can be mounted on the rear underside of each float to help keep a straight path and improve performance (decreasing zigzags, and allowing a greater number of paddle strokes before having to change sides). The boat exhibits high hydrodynamic efficiency and can be disassembled so as to occupy a small volume, making it easy to transport and store.
    • 本发明涉及具有双体船结构的便携式船。 船基本上由两个充气浮子组成,两个连接杆在其端部连接有板,用于将连接杆固定到浮子上。 可以在两个连接杆之间组装刚性平台,形成乘客的甲板。 本发明允许乘客在使用桨来推动船的同时保持站在刚性平台上。 侧面浮标提供更大的稳定性,使乘客更容易保持平衡。 可拆卸的散热片可以安装在每个浮子的后侧,以帮助保持直线路径并提高性能(减少之字形,并且在更换侧面之前允许更多的桨叶冲程)。 该船具有较高的流体动力学效率,可拆卸,占用体积小,易于运输和储存。

    • Disclosed is a method for maintenance of a ship propeller including the steps of: placing a flexible habitat having an open upper end over an uppermost blade and a portion of the propeller hub, and establishing a gas seal between the upper end of the habitat and the blade to close the habitat at its upper end. After fixing the lower end of the habitat relatively to the propeller, compressed gas is preferably introduced into the habitat to displace the water in the habitat. The apparatus for maintenance of a ship propeller under water comprises a flexible habitat with an open upper end. The habitat has a gas seal adapted to cooperate with a propeller blade surface to establish a gas seal to close the habitat at its upper end and fixing means adapted to fix the open lower end of the habitat relatively to the propeller. A means for introducing compressed gas into the habitat is provided.
    • 本发明公开了一种维修船舶螺旋桨的方法,包括以下步骤:将具有敞开的上端的柔性栖息地放置在最上面的叶片和螺旋桨轮毂的一部分上,并在栖息地的上端和 在其上端关闭栖息地。 在将栖息地的下端相对于螺旋桨固定之后,优选将压缩气体引入栖息地以置换栖息地中的水。 用于在水下维护船舶螺旋桨的装置包括具有敞开的上端的柔性栖息地。 栖息地具有适于与螺旋桨叶片表面配合的气体密封件,以建立气体密封件以封闭其上端处的栖息地,并且固定装置适于将栖息地的敞开的下端相对于螺旋桨固定。 提供了一种将压缩气体引入栖息地的手段。
