Abstract
The utility model discloses a variable rudder, including the rudderstock of rudder blade with setting marginal part before the rudder blade, be provided with the steel sheet in the lower part of rudder blade, the leading edge of rudder blade be provided with with steel sheet complex gate, still be provided with pneumatic cylinder and latent oil pump in the rudder blade, set up the airtight chamber of rudder chamber for being equipped with fluid of latent oil pump, dive oil pump and pneumatic cylinder through automatically controlled valve and tube coupling, form the control steel sheet and follow that the rudder blade transversely stretches out and the retract hydraulic control system on gate. The utility model discloses variable rudder, it is through set up steel sheet and the flexible hydraulic control system of drive steel sheet in the rudder blade lower part, when normally navigating by water, the steel sheet is located the rudder blade, the rudder is for coiling the rudder balance, the rudder blade receive rivers influence to, it is stable good to navigate by water, 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.
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 the tubulose rudder bearer etc. of rudder blade, rudder stock, support rudder stock.
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.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of type variable rudder for ship, to solve the larger problem of steering torque needed for unbalanced rudder.
The utility model type variable rudder for ship, comprise rudder blade and the rudder stock being arranged on rudder blade exterior region, 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.
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, the wing flap being hinged on rudder blade rear is also comprised.
The beneficial effects of the utility model:
The utility model type variable rudder for ship, it is by the hydraulic control system arranging steel plate in rudder blade bottom and drive steel plate flexible, and when when normal/cruise, steel plate is positioned at rudder blade, rudder for ship for not coil balanced rudder, rudder blade be subject to 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model type variable rudder for ship;
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 type variable rudder for ship, comprise rudder blade 1 and the rudder stock 2 being arranged on rudder blade exterior region, 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, arranges the rudder chamber 6 of submersible pump for being equipped with the closed chamber of fluid, 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.
The present embodiment type variable rudder for ship, it is by the hydraulic control system arranging steel plate in rudder blade bottom and drive steel plate flexible, and when when normal/cruise, steel plate is positioned at rudder blade, rudder for ship for not coil balanced rudder, rudder blade be subject to 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.
As the improvement to the present embodiment, the leading edge of described steel plate 3 stretches out doorway and the shape of its leading edge is identical with rudder blade leading edge shape, is arc; The leading edge of steel plate 3 is that arc makes the resistance of itself and water less, can reduce fuel oil consumption when navigating by water.
As the improvement to the present embodiment, described hydraulic actuating cylinder 4 and electrically-controlled valve 7 to be arranged in rudder blade independently in closed cavity, described closed cavity wall are provided with maintenance window (maintenance window is not shown in FIG.), are convenient to safeguard.
As the improvement to the present embodiment, this type variable rudder for ship also comprises the wing flap 8 being hinged on rudder blade rear, and wing flap can improve the road-holding property of steerage and boats and ships further.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
