降式スラスタの構造。[Scope of Claim for Utility Model Registration] (1) In an elevating thruster in which the propeller section can be moved upward and retracted using an elevating device, a seal that is installed opposite to a water seal cylinder that is raised and lowered to constantly seal off water outside the vessel. In addition, a preliminary seal is provided on the side closer to the water outside the vessel than the above-mentioned seal, and the preliminary seal is made of a hollow elastic material that can be elastically deformed in the direction of the opposing water seal cylinder by conducting pressure fluid from the outside. The structure of an elevating thruster characterized by being constructed by. (2) A pressure sensor is provided in the packing part of the seal, an on-off valve is provided in the middle of the fluid pressure line for conducting pressure fluid to the preliminary seal, and the pressure sensor and the on-off valve are electrically connected. The structure of an elevating type thruster according to claim (1) of the registered utility model, which controls the opening and closing of an on-off valve according to a detected value of a pressure sensor. (3) At a position closer to the water outside the vessel than the preliminary seal mentioned above, at a position that leaves a very small gap between the outer circumferential surface of the water seal and the water seal, to scrape off any accretions on the circumference of the water seal. A structure of an elevating type thruster according to claim 1 or 2 of the registered utility model, in which a cutter is provided protruding from the hull side.
