When when normally navigating by water, the steel sheet is located the rudder blade, and the rudder is for coiling the rudder balance, the rudder blade receive rivers influence to, navigation stability is good, when ship course -changing, the hydraulic control system steel sheet stretches out the rudder blade, and the rudder changes the semibalance rudder into by unbalanced rudder, and the rudder blade required steering moment diminish, and the steerage is higher, and steering wheel consumed power is lower, and through between rudder blade and the rudderstock, set up seal structure between tubulose rudder bearing and the rudderstock to can prevent the fluid in the rudder blade to get into the fit clearance between rudderstock and rudder blade and the tubulose rudder bearing, can avoid the filth in the fluid to damage the fitting surface.
Description
Technical field
The utility model relates to a kind of ship parts, particularly a kind of rudder for ship.
Background technology
Rudder for ship is attached to outside hull, utilizes and acts on the dynaflow on rudder blade during ship's navigation and the device controlling ship course, be usually made up of rudder blade, rudder stock and tubulose rudder bearer etc.
In prior art, rudder for ship can be divided into balanced rudder, unbalanced rudder and gnomon rudder, and the rudder stock of balanced rudder is near the middle part of rudder blade, and steering torque is little, and rudder blade is poor by water impact navigation stability in water; The steering torque of unbalanced rudder is comparatively large, but rudder blade is less by water hammering effects, and navigation stability is better; The steering torque of gnomon rudder is between balanced rudder and unbalanced rudder.
Meanwhile, along with the rise of international oil price, how to reduce the energy consumption of boats and ships, the economic benefit improving boats and ships also becomes the important subject causing industry.And found by research, there is an obvious meiobar in the rear, center of screw propeller promoting boats and ships, the current in this region are very disorderly and have eddy current, and this part current can not play progradation to boats and ships, can reduce capacity usage ratio and the economic benefit of boats and ships.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of type variable rudder for ship with rectifier structure, to solve the larger problem of steering torque needed for unbalanced rudder; And solve the problem of propeller center rear turbulent flow to boats and ships energy ezpenditure.
The utility model has the type variable rudder for ship of rectifier structure, comprise rudder blade and rudder stock, 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, and 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 is just provided with rudder ball in the leading edge of propeller center, and described rudder ball is column, and the front end arcwall face of rudder ball has a sharp apex.
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 rudder ball also comprises the fusiformis rear along rudder blade horizontally set.
Further, the type variable rudder for ship described in rectifier structure also comprises the wing flap being hinged on rudder blade rear end.
The beneficial effects of the utility model:
1, the utility model has the type variable rudder for ship of rectifier structure, and 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 has the type variable rudder for ship of rectifier structure, it by arranging hermetically-sealed construction between rudder blade and rudder stock, between tubulose rudder bearer and rudder stock, thus the fluid in rudder blade can be stoped to enter rudder stock and the tolerance clearance between rudder blade and tubulose rudder bearer, the dirt in fluid can be avoided to damage fitting surface, and avoid greasy dirt to cause rudder stock to rotate the problem such as alerting ability variation and maintenance dismounting difficulty.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model has the type variable rudder for ship of rectifier structure;
Fig. 2 is the cutaway view along A-A in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment has the type variable rudder for ship of rectifier structure, comprise rudder blade 1 and rudder stock 2, steel plate 3 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, is also provided with hydraulic actuating cylinder 4 and submersible pump 5 in described rudder blade, and the rudder chamber arranging submersible pump is the closed chamber 6 that fluid is housed, described submersible pump is connected with pipeline by electrically-controlled valve 7 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 is just provided with rudder ball 8 in the leading edge of propeller center, and described rudder ball is column, and the front end arcwall face of rudder ball has a sharp apex 9.
The present embodiment has the type variable rudder for ship of rectifier structure, and 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.
