Abstract
The utility model discloses a light long -life adjustable -pitch propeller, include: thick liquid hub, paddle and rotating circular disk, the rotating circular disk passes through the connecting pin and installs thick liquid hub periphery, the paddle is installed on the rotating circular disk, thick liquid hub internally mounted has rotary mechanism, rotary mechanism can drive the rotating circular disk rotates, and thick liquid hub, paddle and rotating circular disk all adopt the high corrosion resistant ABS plastics of high strength to make. In this way, the utility model has the characteristics of simple structure, the quality is light, propulsive efficiency is high, long service life.
Description
Technical field
The utility model relates to screw propeller field, particularly relates to a kind of lightweight long life adjustable pitch propeller.
Background technology
Marine propeller promotes the mechanism that boats and ships advance, and screw propeller is installed on stern underwater, obtains power and rotating by marine main engine, after pushing water to ship, utilizes the antagonistic force of water to push boat advance.Current propeller for vessels is commonly used Cu alloy material and is made, due to the salt water contamination aggravation of bay and river waters in recent years, the corrosion resisting property of copper alloy propeller also starts to go wrong, because of the discharge of industrial waste water and municipal effluent, organic matter in seawater is rolled up, cause anaerobic desulfovibro amount reproduction, after the sulfate in seawater is reduced, create sulphion copper alloy to strong corrosion effect.Therefore, the destruction that copper alloy propeller causes because of this corrosion often has generation, even only use a few days screw propeller surface just turn black and coarse can't bear.
Replace the new direction that the good propeller material of the new type corrosion resistant performance of copper alloy just becomes propeller material exploitation.
Utility model content
The technical matters that the utility model mainly solves is: for the deficiencies in the prior art, a kind of lightweight long life adjustable pitch propeller is provided, the good highstrenghtpiston of corrosion resisting property is adopted to make, and blade can according to boats and ships regulating working conditions operating angle, have that structure is simple, quality is light, propulsion coefficient is high, the feature of long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of lightweight long life adjustable pitch propeller, comprise: slurry hub, blade and rotating circular disk, described rotating circular disk is arranged on described slurry hub periphery by connecting pin, described blade is arranged on described rotating circular disk, described slurry hub inside is provided with rotating mechanism, described rotating mechanism can drive described rotating circular disk to rotate, and described slurry hub, blade and rotating circular disk all adopt the ABS plastic of high strength highly corrosion resistant to make.
In the utility model preferred embodiment, described blade and rotating circular disk have 2-4, are distributed on the periphery of described slurry hub.
In the utility model preferred embodiment, described blade comprises guide margin and lagging edge, and described guide margin is circular arc line style, described lagging edge linearly type.
The beneficial effects of the utility model are: the utility model adopts the good highstrenghtpiston of corrosion resisting property to make, and be provided with rotating circular disk and rotating mechanism, this rotating mechanism can drive described rotating circular disk to rotate, and then driving described blade to regulate operating angle, this screw propeller has that structure is simple, quality is light, propulsion coefficient is high, the feature of long service life.
Accompanying drawing explanation
