Abstract
The utility model is related to the marine propeller that a kind of blade has wing fence, and propeller is made up of blade, propeller hub and wing fence.Blade 1 is fixed on propeller hub 2, and wing fence 3 is a thin slice for having one fixed width, mounted in the front of blade 1, lagging edge is continued up to from the guide margin of blade, the narrow edge direction of wing fence is vertical with blade surface.The long side of wing fence is in arc-shaped, and its center of circle coincides with propeller hub axle center, can there is the wing fence of several isocentric circular arcs on a blade.Blade has the marine propeller of wing fence, using the wing fence on propeller blade front, blocks the radial direction current produced during propeller rotational, improves the operating efficiency of propeller.
Description
Technical field
The utility model is related to the marine propeller that a kind of blade has wing fence, using the wing fence on propeller blade front,
The radial direction current produced during propeller rotational are blocked, the operating efficiency of propeller is improved.
Technical background
Now, many ships all use propeller as propulsive element, and propeller absorbs marine main engine work(with its rotation
Rate, forms the thrust of ship motion.When propeller is rotated in water, under the promotion of blade, the current of both direction can be produced,
One kind is axial current, and axial current produce the thrust of ship motion；Another is radial direction current, and radial direction current are to ship running
There is no any contribution, simply consume marine main engine power, making the operating efficiency of propeller reduces.
The content of the invention
The marine propeller that a kind of blade has wing fence is made up of blade, propeller hub and wing fence.Blade is fixed on propeller hub, wing fence
For a thin slice for having one fixed width, mounted in blade front, lagging edge, the narrow edge direction and oar of wing fence are continued up to from blade guide margin
Leaf surface is vertical.The long side of wing fence is in arc-shaped, and its center of circle coincides with propeller hub axle center, can have several concentric circles on a blade
The wing fence of arc.
The concrete technical scheme that the utility model is taken is that a kind of blade has the marine propeller of wing fence by blade, propeller hub
Constituted with wing fence.Blade is fixed on propeller hub, and wing fence is a thin slice for having one fixed width, mounted in blade front, from blade guide margin
Lagging edge is continued up to, the narrow edge direction of wing fence is vertical with blade surface, the long side of wing fence is in arc-shaped, its center of circle and propeller hub axle center
Coincide, there can be the wing fence of several isocentric circular arcs on a blade.
The beneficial effects of the utility model are, in propeller rotational, and the wing fence on blade front blocks current in blade
Positive Radial Flow, reduces the raw energy loss of radial water miscarriage, it is possible to increase the operating efficiency of propeller.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Figure of description is the front view and top view for the three leaf marine propellers that a kind of blade has wing fence, wherein, Fig. 1 is
Front view, Fig. 2 is top view.In fig. 1 and 2,1 is blade, and 2 be propeller hub, and 3 be wing fence.Wing fence has one fixed width for one
Thin slice, mounted in the front of blade, lagging edge is continued up to from blade guide margin, the long side of wing fence is in arc-shaped, its center of circle and propeller hub axle
The heart coincides, and the narrow edge direction of wing fence is vertical with blade surface.There can be several isocentric circular arc wing fences on one blade, in figure
Represented example is to have three wing fences on three leaf oars, each blade.Propeller can be 2 leaves or multi-blade propeller, propeller
Each blade can have one or more isocentric circular arc wing fences.
Embodiment
Figure of description show the front view (Fig. 1) and top view that a kind of blade has three leaf marine propellers of wing fence
(Fig. 2), wherein 1 is blade, 2 be propeller hub, and 3 be wing fence.Wing fence is a thin slice for having an one fixed width, mounted in the front of blade, from
Blade guide margin continues up to lagging edge, and the long side of wing fence is in arc-shaped, and its center of circle coincides with propeller hub axle center, the narrow edge direction of wing fence
It is vertical with blade surface.There can be the wing fence of several isocentric circular arcs on one blade, example represented in the accompanying drawings is three leaves
There are three wing fences on oar, each blade.Propeller can be 2 leaves or multi-blade propeller, and each blade of propeller can have one
Individual or multiple isocentric circular arc wing fences.
