Abstract
The invention discloses a marine propeller. The marine propeller comprises a wheel hub, wherein a plurality of propeller blades are fixedly mounted at the side periphery of the wheel hub; the surface of each propeller blade is a curved surface; an arc-shaped grid plate is fixedly connected between every two adjacent propeller blades; the arc-shaped grid plates encircle the axis of the wheel hub, so that an annular pressurization system is formed; the surface radian formed by the pressurization system is matched with the curved-surface curvature formed by the surfaces of the propeller blades. By adopting the marine propeller disclosed by the invention, the pressure generated by the propeller can be increased, so that the power of the propeller is increased; the marine propeller is simple in structure, convenient to manufacture, and low in production cost.
Description
Technical field
The present invention relates to marine equipment, particularly relate to a kind of marine propeller.
Background technology
Along with improving constantly of science and technology, ship industry is more and more flourishing, and people are also more and more higher for the requirement of boats and ships, screw propeller is a kind of is the propelling unit of propulsive force by turn of engine power conversion, and be the important component part in boats and ships, its performance requriements is particularly important, and traditional screw propeller all adopts the propeller blade of a specification to realize advancing, but the limited pressure that such screw propeller is formed, thus cause its propulsive force less, the fast-developing requirement of science and technology now cannot be met.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of marine propeller, can promote the pressure that screw propeller causes, thus promotes the power of screw propeller, and structure is simple, and easily manufactured, productive costs is also lower.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of marine propeller, comprise: wheel hub, the side periphery of described wheel hub is installed with multiple propeller blade, each described propeller blade surface is curved surface, and arc web plate is fixedly connected with between each two adjacent propeller blades, each described arc web plate forms the pressure charging system of ring-type around the axis of wheel hub, and the surperficial radian that described pressure charging system is formed matches with the surperficial curved surface curvature formed of described propeller blade.
In a preferred embodiment of the present invention, the material of described arc web plate is high-speed alloy steel.
In a preferred embodiment of the present invention, the thickness of described arc web plate is identical with the thickness of described propeller blade.
In a preferred embodiment of the present invention, the mesh diameter of described arc web plate is 1-2cm.
The invention has the beneficial effects as follows: the present invention can promote the pressure that screw propeller causes, thus promote the power of screw propeller, structure is simple, and easily manufactured, productive costs is also lower.
Accompanying drawing explanation
Fig. 1 is marine propeller of the present invention structural representation in a preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, wheel hub, and 2, propeller blade, 3, web plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention is:
A kind of marine propeller, comprise: wheel hub 1, the side periphery of described wheel hub 1 is installed with multiple propeller blade 2, each described propeller blade 2 surface is curved surface, and arc web plate 3 is fixedly connected with between each two adjacent propeller blades 2, each described arc web plate 3 forms the pressure charging system of ring-type around the axis of wheel hub 1, and the curved surface curvature that the surperficial radian that formed of described pressure charging system and described propeller blade 2 surface are formed matches.
Wherein, the material of described arc web plate 3 is high-speed alloy steel, can ensure that arc web plate 3 has stronger corrosion stability and higher hardness, improves service life.
The thickness of described arc web plate 3 is identical with the thickness of described propeller blade 2; The mesh diameter of described arc web plate 3 is 1-2cm.
Be different from prior art, present invention is disclosed a kind of marine propeller, its main operation logic is: when wheel hub 1 starts High Rotation Speed, the curved surface on propeller blade 2 surface will form the pressure of one driven forward, and the radian now formed due to arc web plate 3 surface is identical with the curvature on propeller blade 2 surface, the pressure that the pressure that arc web plate 3 is formed in the process of High Rotation Speed can be formed with propeller blade 2 is superimposed, thus realizes advancing.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
