The invention belongs to the technical field of ships, and discloses a hinge type rudder system underwater inspection structure, which comprises a rudder blade, a cover plate, a plurality of seat plates and a hinge unit, the rudder blade is provided with an inspection hole, the outer side of the cover plate is flush with the outer side of the rudder blade, the edge of the cover plate is circumferentially provided with a plurality of notches at intervals, the seat plates are connected to the cover plate, and the seat plates are embedded into the notches in a one-to-one correspondence manner. The shape of the cross section of the seat plate is the same as that of the notch, the outer side of the seat plate does not exceed the outer side of the cover plate, the seat plate can be detachably connected with the rudder blade through the fixing piece, and the two ends of the fixing piece in the length direction do not exceed the outer side of the cover plate, so that adverse effects on the steering performance of a rudder system are avoided, and cavitation corrosion of the rudder system is prevented; the hinge unit comprises a hinge seat and a hinge arm, the hinge seat is arranged on the inner side of the rudder blade, one end of the hinge arm is hinged to the hinge seat, the other end of the hinge arm is connected to the inner side of the cover plate, the cover plate is rotationally connected to the rudder blade through the hinge unit, when the inspection hole is opened, the cover plate does not need to be completely disassembled, and workers can independently finish opening.

    本发明属于船舶技术领域,公开了一种铰链式舵系水下检验结构,包括舵叶、盖板、座板及铰接单元,舵叶设有检验孔,盖板的外侧与舵叶的外侧齐平,盖板的边沿周向间隔开设有多个缺口,座板设有多个且均连接于盖板,座板一一对应嵌入缺口,座板的截面形状与缺口的形状相同,座板的外侧不超出盖板的外侧,座板能通过固定件可拆卸连接舵叶,固定件沿其长度方向的两端均不超出盖板的外侧,避免对舵系操纵性能产生不利影响,防止舵系的空泡腐蚀;铰接单元包括铰接座以及铰接臂,铰接座设置于舵叶的内侧,铰接臂的一端铰接于铰接座,另一端连接于盖板的内侧,盖板通过铰接单元转动连接于舵叶,在开启检验孔时,不需将盖板完全拆下,工作人员可以单独完成。
