Abstract
The utility model discloses a novel double suspension streamline type flap rudder for an engineering ship and belongs to the field of ships. The novel double suspension streamline type flap rudder comprises a ship body, a primary rudderstock, primary rudders, flaps, connecting blocks and secondary rudderstock holes, wherein the tail of the ship body is provided with two primary rudders; the two primary rudders are arranged at the tail of the ship body through the primary rudderstock; the left sides of the primary rudders are provided with the flaps through the connecting blocks; the secondary rudderstock holes are formed in the flaps; an outwards convex arc is formed on the right sides of the flaps; an inwards concave arc is formed on the left sides of the flaps; the outwards convex arc is in clearance fit with the inwards concave arc; and pneumatic rotating heads are arranged on the connecting blocks. By the engineering ship, when the primary rudders are rotated to a maximum angle, the flaps can continuously rotate to enlarge the rotating angle; and therefore, the flexibility of the ship is greatly improved.
Description
Technical field
The utility model relates to a kind of two suspension stream line pattern flaps of new type of engineering ship, belongs to ship domain.
Background technology
Along with the fast development of marine economy, the marine engineering ship is also more and more, but present auxiliary vessel is traditional single rudder structure of single screw basically; And rudder all is the ordinary rudder of integral type; Reverse dumb and the radius of gyration limited, turning efficient is low, maneuvering performance is poor; Therefore greatly reducing the alerting ability of boats and ships, is a urgent problem at present.
Summary of the invention
The purpose of the utility model provides a kind of two suspension stream line pattern flaps of new type of engineering ship.
What the utility model will solve is that existing ordinary rudder reverses dumb and the radius of gyration is limited, turning efficient is low, the deficiency of maneuvering performance difference, thereby improves the efficient of existing ordinary rudder, improves maneuvering performance.
For realizing the purpose of the utility model, the technical scheme that the utility model adopts is:
A kind of two suspension stream line pattern flaps of new type of engineering ship; Comprise hull, rudder main stock, main rudder, wing flap, contiguous block, secondary rudder hole; The hull afterbody is provided with two main rudders, and main rudder is installed in the hull afterbody through rudder main stock, and main rudder passes on left contiguous block wing flap is installed.
Wing flap is provided with secondary rudder hole, and the wing flap right side forms evagination circular arc, and the main rudder left side forms indent circular arc, and both form free-running fit, and contiguous block is provided with pneumatic rotating head.
The utility model has the advantages that: this auxiliary vessel is after main rudder turns to maximum angle, and wing flap can be rotated further to enlarge rotational angle, has therefore improved the alerting ability of ship greatly, should have the vast market space.
Description of drawings
Fig. 1 is the schematic perspective view of two suspension stream line pattern flaps of a kind of new type of engineering ship of the utility model;
Fig. 2 is the enlarged diagram of two suspension stream line pattern flap rudder blades of a kind of new type of engineering ship of the utility model;
Among the figure: 1, hull 2, rudder main stock 3, main rudder 4, wing flap 5, contiguous block 6, secondary rudder hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in the figure; A kind of two suspension stream line pattern flaps of new type of engineering ship; Comprise hull 1, rudder main stock 2, main rudder 3, wing flap 4, contiguous block 5, secondary rudder hole 6; Hull 1 afterbody is provided with two main rudders 3, and main rudder 3 is installed in hull 1 afterbody through rudder main stock 2, and main rudder 3 passes on left contiguous block 5 wing flap 4 is installed.
The method of application of this device: the main frame that starts in the hull 1 drives twin screw 2 rotations; When auxiliary vessel need be turned; After main rudder 3 turns to maximum angle; Wing flap 4 can be rotated further to enlarge rotational angle, can make the ship flipper turn and reduce turn radius, has therefore improved the alerting ability of ship greatly.
