Abstract
The utility model relates to a device for boat to efficiently solve the problem of lower dynamical stability in the sail of displacement boat and wing slide boat. The utility model is positioned on the novel stern fin of the stern portion of the displacement boat of the compound high-performance wing sliding boat formed by the boat body of shallow V-shaped stern sliding surface and head piercing hydrofoil or the displacement boat of shallow V-shaped stern sliding surface. The utility model is characterized in that the stern fins are positioned on the boat stern in pair. The main board comprising a main board and a fin board is connected with the lower edge of a closing board of the boat stern by a hinge or a connecting axle and the fin board is connected with the outside edge of the main board. The utility model can improve the sailing dynamical stability of the displacement boat or the wing sliding boat by adjusting the main board or the fin board angle to sufficiently guarantee the sailing safety performance and effectively improve the integrated technical economy performance.
Description
Technical field
The utility model relates to marine gear, refers in particular to a kind of gliding-hydrofoil craft and glider with performance-oriented novel stern fin.
Technical background
Present high speed vessel particularly glider mainly adopts wave suppression plate to be used to improve ship resistance and performance, because this wave suppression plate generally is an one flat plate, dynamic stability is poor during the glider navigation, causes safety of navigation decline, ensures sometimes even not; And head puts that to cut when drawing the gliding-hydrofoil craft navigation moving longitudinal stability not ideal, all has a lot of deficiencies.
Summary of the invention
The purpose of this utility model is under the prerequisite that keeps glider and the good rapidity of gliding-hydrofoil craft, solves the problem of glider and gliding-hydrofoil craft navigation dynamic stability difference effectively, provides a kind of gliding-hydrofoil craft and glider novel stern fin.
The utility model is the novel stern fin of the composite high-performance gliding-hydrofoil craft stern that constitutes of a kind of glider that is installed on shallow V-arrangement stern planing surface or shallow V-arrangement stern planing surface hull and first surface piercing hydrofoils, it is characterized in that the stern fin is arranged in the ship stern in pairs, constitute mainboard by mainboard and fin keel and link by hinge or coupling spindle and ship stern transom plate lower edge, fin keel is connected in the mainboard outer ledge.
Wherein fin keel with mainly contain two types connecting of mainboard:
A kind of for fin keel is fixed in the mainboard outer ledge, can whole rotate around ship stern transom plate lower edge;
Another kind links by coupling spindle and mainboard outer ledge for fin keel, and fin keel can be around its edge adapter shaft rotation.
Mainboard and fin keel aspect are one of trapezoidal or common quadrangle of rectangle.
Mainboard vertical profile cross section is a rectangle, and fin keel vertical profile cross section is airfoil or arc or crescent.
The advantage of the utility model stern fin is to improve glider or gliding-hydrofoil craft navigation dynamic stability in real time by adjusting mainboard or fin keel angle, makes safety of navigation fully be ensured, has improved its complex art economic performance effectively.

The specific embodiment
The utility model mainly cooperates with shallow V-type stern planing surface line style, is arranged in the ship stern in pairs, and manufactured materials generally adopts ordinary steel or high intensity for ship steel, also can adopt glass-felt plastic, aluminum alloy materials manufacturing.According to ship stern type and main frame and propelling unit deployment scenarios, mainboard (1) and fin keel (2) aspect can be the trapezoidal or common quadrangle of rectangle, and mainboard vertical profile cross section is a rectangle; Fin keel vertical profile cross section is airfoil shown in Fig. 5,6,7 or arc or crescent.
Fig. 1, fin keel fixed shown in Figure 2, the stern fin is arranged in the ship stern in pairs, constitute by mainboard (2) and fin keel (1), mainboard (2) front side links by the stern transom plate lower edge of hinge (4) with ship stern (5), fin keel (1) is fixedly linked in mainboard (2) outer ledge, and the two ends of telescopic oil cylinder (3) link to each other with mainboard (2) rear side with the stern transom plate of ship stern (5) respectively by hinge (4).
Fig. 3, fin keel adjustable type shown in Figure 4, its difference is that fin keel (1) links by fin keel hinge (8) and mainboard (2) outer ledge, the coupling spindle of fin keel hinge (8) links to each other with crowned teeth coupling (7) rear end, and crowned teeth coupling (7) front end links to each other with the mouth of rotary oil cylinder (6).
For different ships and light boats types, the utility model is taked different layouts:
Be symmetrically arranged in the outboard engine both sides;
Be symmetrically arranged in both sides behind the screw propeller of single-blade aircraft cockpit ship;
Be symmetrically arranged in the screw propeller rear side of two oar aircraft cockpit ships.
