The utility model type variable rudder for ship easy to assemble, comprise rudder blade, rudder stock, secondary rudderpost, by the hinged wing flap of secondary rudderpost and rudder blade and the connecting rod being connected rudder stock and secondary rudderpost, steel plate is provided with in the bottom of described rudder blade, the leading edge of described rudder blade is provided with the doorway coordinated with steel plate, hydraulic actuating cylinder and submersible pump is also provided with in described rudder blade, the rudder chamber arranging submersible pump is the closed chamber that fluid is housed, described submersible pump is connected with pipeline by electrically-controlled valve with hydraulic actuating cylinder, and formation control steel plate crosses out along rudder blade and the hydraulic control system on doorway of retracting;
Described rudder blade comprises rudder blade body and rudder blade lid, and described rudder blade body is provided with assembling window, and described rudder blade lid is fixed by screws on assembling window, and described rudder stock, secondary rudderpost and connecting rod are arranged in the region that rudder blade lid covers.
Further, the leading edge of described steel plate stretches out doorway and the shape of its leading edge is identical with rudder blade leading edge shape, is arc.
Further, described hydraulic actuating cylinder and electrically-controlled valve to be arranged in rudder blade independently in closed cavity, and described closed cavity wall is provided with maintenance window.
Further, described secondary rudderpost comprise axis body and be connected with axis body upper end detachable hinged seat, described hinged seat is connected by key in a circumferential direction with axis body upper end, and described axis body upper end is connected by screw the cover plate preventing hinged seat from coming off.
The beneficial effects of the utility model:
1, the utility model type variable rudder for ship easy to assemble, it is by the hydraulic control system arranging steel plate in rudder blade bottom and drive steel plate flexible, when when normal/cruise, steel plate is positioned at rudder blade, rudder for ship for not coil balanced rudder, rudder blade by water currents to, navigation stability is good; When ship turning, hydraulic control system controls steel plate and stretches out rudder blade, and rudder for ship changes gnomon rudder into by unbalanced rudder, and needed for rudder blade, steering torque diminishes, and steerage is higher, and steering wheel consumed power is lower.
2, the utility model type variable rudder for ship easy to assemble, it by arranging assembling window and rudder blade lid on main rudder leaf, when the inner structure of main rudder leaf breaks down, open rudder blade lid, can easily the part such as secondary rudderpost, connecting rod, axle sleeve, lining, bearing in main rudder leaf be dismantled and be keeped in repair, thus the dismounting difficulty of reduction connecting rod rudder that can be very large, improve servicing ease and maintenance work efficiency.
3, the utility model type variable rudder for ship easy to assemble, its secondary rudderpost is improved to axis body and hinged seat detachable unitized construction by existing integral structure, has further facilitated the dismounting to secondary rudderpost and maintenance difficulty.
