Abstract
An efficient and powerful boat propeller consists of a hub and a plurality of paddles. Convex line fishtail lines are arranged on the thrashing surface of each paddle, and the thrashing surface is manufactured into an entire rough surface; the paddles are made of metal materials; the thrashing surface of each metal paddle is coated with a layer of tire rubber surface; and convex line fishtail lines are arranged on the tire rubber surface which is manufactured into an entire rough surface. The propeller has the advantages of simple structure, and convenient and reliable use. Furthermore, boat thrust power is increased when the propeller is used, the thrust power of the propeller is usually increased by 15 to 30 percent, the mute effect can be achieved, etc.
Description
Technical field
What the present invention relates to is a kind of propelling unit peculiar to vessel that is exclusively used in, especially a kind of vigorous propeller efficiently peculiar to vessel.
Background technology
In the prior art, the boats and ships that sail on the water realize that by ship propeller this ship propeller comprises that diesel engine for boats is used as power, by transmission shaft connecting bolt oar, make screw propeller fast rotational paddling current, and make it to produce antagonistic force, promote boats and ships and advance.The surface of the smoother during face of striking waters of the screw propeller known to us at present, it carries out design-calculated based on hydromechanical theory, and the blade face of screw propeller is shape in the shape of a spiral, and it can produce a kind of effect of striking.But the screw propeller design on the smooth blade face of this employing does not conform to some experiences in our daily life., before watching weightlifter's hand to lift barbell, on palm, be coated with always and spread some white powder, and then go grasping to have the barbell of anti-skidding asperities as us, carry out weight lifting competition.These white powders can increase the friction between hand and the barbell in the magnesium powder, prevent the slippage of hand, and the sportsman is made energetically, go out power.If instead the sportsman is before weight lifting competition, at the lubricant of smearing machine oil, butter or petroleum ointment and so on hand of oneself, and that employed barbell is a root is very smooth, the non-standard barbell that do not have anti-skidding thin asperities, so, the sportsman can only lift him and can lift 30% or 50% of weight at ordinary times.That is to say the existence owing to smooth side, the weight lifting achievement will reduce greatly.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and a kind of screw propeller blade face friction coefficient of striking waters that can strengthen is provided, strengthen the high-efficiency vigorous propeller for ship of propeller thrust.
The objective of the invention is to finish by following technical solution, described screw propeller mainly is made up of wheel hub and many blades, and the described blade surface of striking waters is provided with the convex line crow's feet and is made into holistic rough surface.
Described blade is made with metallic material, and it is compounded with one deck rubber for tire face on the surface of striking waters of metal blade, and this rubber for tire face is provided with the convex line crow's feet and is made into holistic rough surface.
Screw propeller of the present invention mainly is to convert centnifugal force to actv. thrust, what play is a kind of effect of striking, increase the strike waters roughness on surface of screw propeller, can significantly improve the dynamics of striking, also promptly increase centnifugal force, thereby it have simple in structure, easy to use and reliable, increased the propulsion of ship power when screw propeller uses, the thrust of screw propeller increases 15-30% usually, and can reach quiet characteristics such as effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in the accompanying drawing 1, the present invention mainly is made up of wheel hub 1 and many blades 2, and described blade 2 surface of striking waters is provided with convex line crow's feet 3 and is made into holistic rough surface 4.This blade 2 can be made with metal or non-metallic material, is made by the high-strength carbon fiber material as non-metal etc.Blade of the present invention also can be made with metallic material, and it is compounded with one deck rubber for tire face on the surface of striking waters of blade, and this rubber for tire face is provided with the convex line crow's feet and is made into holistic rough surface.Owing to the invention belongs to a kind of improvement to prior art, those of ordinary skill in the art can implement the present invention easily on understanding basis of the present invention.
