Abstract
The utility model provides a paddle-rudder integrated device with concavo-convex guiding rims. Concave-convex blades are symmetrically mounted on a propeller hub, one sides of the concave-convex blades are blade arc sides, and the other sides are blade concave-convex guiding rims; a rudder plate straight edge is arranged on the front side of a rudder plate, and a rudder plate concave-convex guiding rim is arranged on the back side of the rudder plate. According to the utility model, through the arrangement of the concave-convex guiding rims on a propeller and the rudder plate, the operation resistances of the propeller and a rudder are reduced, and energy conservation is achieved. The paddle-rudder integrated device is suitable for being used as the paddle and the rudderof a ship.
Description
Technical field
The utility model provides the device that ship power drives, the specifically concavo-convex oar rudder integrated apparatus of guide lug.
Background technology
The effect of oar rudder integrated apparatus is to provide the power advancing and the maneuvering performance that guarantees boats and ships to boats and ships.Tradition oar rudder integrated apparatus expends the huge energy when work.Therefore energy-conservation is key problem in technology of the present utility model.
Summary of the invention
For the energy-conservation problem of oar rudder, the utility model provides guide lug concavo-convex oar rudder integrated apparatus, and this device, by screw blade and rudder, concaveconvex structure being set, solves and improves oar rudder operating efficiency and energy-conservation technical matters.
The scheme that the utility model technical solution problem adopts is:
On propeller hub, be symmetrically installed with concavo-convex blade, concavo-convex blade one side is blade arc limit, and opposite side is the concavo-convex guide lug of blade;
Rudder plate front side is provided with rudder plate straight flange, and rear side is provided with the concavo-convex guide lug of rudder plate.
Good effect, the utility model, by concavo-convex guide lug is set on screw propeller and rudder plate, reduces the running resistance of screw propeller and rudder, realizes energy-conservation.Suitablely as ship propeller rudder, apply.
Accompanying drawing explanation
Fig. 1 is the utility model screw propeller front view
Fig. 2 is the utility model screw propeller lateral plan
Fig. 3 is the utility model rudder plate schematic diagram
in figure,1. concavo-convex guide lug 2. propeller hubs of concavo-convex blade 1.1. blade arc limit 1.2. blade, 3. rudder plate, 3.1. rudder plate straight flange, the concavo-convex guide lug of 3.2. rudder plate.
The specific embodiment
Shown in Fig. 1 and Fig. 2, on propeller hub 2, be symmetrically installed with concavo-convex blade 1, concavo-convex blade one side is blade arc limit 1.1, opposite side is the concavo-convex guide lug 1.2 of blade;
Shown in Fig. 3, rudder plate 3 front sides are provided with rudder plate straight flange 3.1, and rear side is provided with the concavo-convex guide lug 3.2 of rudder plate.
Concavo-convex guide lug on rudder plate is the symmetrical crest of many groups and trough shape.
The concavo-convex oar rudder integrated propulsion device of guide lug is arranged on the stern of boats and ships, after marine rudder is positioned at screw propeller, screw propeller is connected with ship stern by oar axle, when flowing through hull, incoming flow arrives before concavo-convex screw propeller oar dish, the concavo-convex guide lug of blade first contacts with current, concavo-convex guide lug trough place at screw propeller can produce the vortex of contrarotation, and the vortex of rotation injects power in liquid stream, and the energy of incoming flow is re-used.Increase the thrust of screw propeller, reduced the resistance of screw propeller, improved the efficiency of screw propeller.
Incoming flow flows through the concavo-convex guide lug of rudder plate for screw propeller arrived ship, trough place at concavo-convex guide lug also can produce the vortex of contrarotation, identical with screw propeller, and the vortex of contrarotation refills power in fluid, improve the lift of marine rudder, strengthened the road-holding property of rudder.
The utility model preferred version is:
The screw propeller of selecting is Ka systematic propeller sequential, and diameter is 0.5m, and number of blade is 4, and sinusoidal wave height is 0.005m;
The concavo-convex rudder aspect ratio that the utility model is selected is 1:1, and sinusoidal wave height is also 0.005m;
Propeller hub center is R to the distance of blade limb, and the radius of the propeller-blade section in the propeller hub center of circle is r, r/R=1,0.8,0.6,0.4, the 0.2nd, sinusoidal balance position, r/R=0.9, the 0.5th, crest location, r/R=0.3, the 0.7th, sinusoidal wave trough position.
