Abstract
The invention discloses a ducted propeller which comprises a propeller hub (2). A duct (1) is arranged inside the propeller hub (2), and four blades (3) are arranged and uniformly distributed on the propeller hub (2); the duct (1) is a hollow duct, and the propeller hub (2) and the center of the duct (1) are arranged on the same horizontal line. The duct of the ducted propeller is hollow, and the blades are uniformly distributed on the propeller hub, so that when the blades rotate, water flow passes through the hollow duct, the resistance to the water flow is reduced, the propulsive efficiency of the propeller is improved, and the operating speed is accelerated.
Description
Technical field
The present invention relates to propeller for vessels technical field is and in particular to a kind of conduit is starched.
Background technology
Propeller is the propeller form being most widely used on current various ships, and it can be by 70% about machine
Tool power-conversion is propulsive force, has the advantages that simple structure, cheap, easy to use and efficiency are higher.Enter 21
Century, environment and energy problem's situation are more and more severeer.Shipping as the prevailing traffic strength of commodity logistics, in shipping
A large amount of non-renewable energy resources amplification quantity dusty gass and greenhouse gases side by side are consumed, for this situation, International Maritime group in journey
Knit and be proposed Ship Design energy efficiency indexes, enforced in 13 years, therefore, development ship hydrodynamics power-saving technology is compeled in eyebrow
Eyelash.And improving propeller propulsive efficiency is one of important development direction of ship hydrodynamics power-saving technology.
In addition to improving propulsive efficiency, the mankind's also more and more higher of the requirement to ship comfortableness.Existing Design of Propeller
Method, while improving efficiency, often sacrifices cavity and noiseproof feature.The deterioration of cavity and noiseproof feature is except affecting ship
Outside oceangoing ship comfortableness, also can disturb the sound field environment of marine organisms life, impact is halobiontic to look for food and health.
Propeller for vessels theoretical developments have gone up the history of a century so far, are passed by diameter, disk ratio and skew back optimization etc.
System method has almost accomplished ultimate attainment, propeller efficiency, cavitation oscillation pressure and noise etc. come the technological means to improve its performance
The lifting further of performance encounters larger technical bottleneck.How moreover it is possible to fall while ensureing propeller high propulsive efficiency
Fluctuation pressure is steeped in low latitude and hydrodynamic noise is always the difficult problem in impeller design field.
Marine propeller is the mechanism promoting ship to advance, and propeller is installed on stern underwater, is obtained by marine main engine
Power and rotate, water is pushed to after ship, is pushed boat advance using the counteracting force of water.
With the increase of larger-sized vessel and the speed of a ship or plane, the load of propeller is bigger, and existing propeller for vessels is due to blade
Stream loss, wake flow contraction after propeller etc. of point make its propulsive efficiency not high, therefore existing propeller for vessels can not be expired
The angle of rake requirement of sufficient large ship.
Content of the invention
In place of the present invention is directed to the deficiencies in the prior art, provide a kind of conduit slurry.
The present invention solve prior art problem scheme be：A kind of conduit slurry, including hub, is provided with described hub and leads
Pipe, described hub is provided with blade.
Further preferred as this programme, the quantity of described blade is 4.
Further preferred as this programme, described blade is evenly distributed in hub.
Further preferred as this programme, described conduit is hollow tubing conductor.
Further preferred as this programme, the center of circle of described hub and conduit is in the same horizontal line.
Beneficial effects of the present invention：The present invention provides a kind of conduit slurry can effectively improve the propulsive efficiency of propeller.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the left view of the present invention.
In figure：1st, conduit；2nd, hub；3rd, blade.
Specific embodiment
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clearly defining.
As shown in Figure 1, 2, a kind of conduit slurry, including hub（2）, described hub（2）Inside it is provided with conduit（1）, described hub
（2）It is provided with blade（3）.
Further preferred as this programme, described blade（3）Quantity be 4.
Further preferred as this programme, described blade（3）It is evenly distributed on hub（2）On.
Further preferred as this programme, described conduit（1）For hollow tubing conductor.
Further preferred as this programme, described hub（2）With the center of circle of conduit in the same horizontal line.
A kind of conduit of conduit slurry that the present invention provides is hollow, and blade is evenly distributed in hub, so working as blade
During rotation, current pass through hollow tubing conductor, decrease the resistance of current, improve the fltting speed of propeller, accelerate operation speed
Degree.
Beneficial effects of the present invention：The present invention provides a kind of conduit slurry can effectively improve the propulsive efficiency of propeller.
For a person skilled in the art, it still can be carried out to the technical scheme described in foregoing embodiments
Wherein some technical characteristics or are carried out equivalent by modification, all within the spirit and principles in the present invention, made any
Modification, equivalent, improvement etc., should be included within the scope of the present invention.
Claims (5)
1. a kind of conduit slurry, including hub（2）It is characterised in that：Described hub（2）Inside it is provided with conduit（1）, described hub（2）
It is provided with blade（3）.
2. conduit as claimed in claim 1 slurry it is characterised in that：Described blade（3）Quantity be 4.
