Abstract

The utility model relates to a fluid centrifugal propulsion device; one end of the device is completely opened, and a rotator composed of a round disc, a paddle and a shaft is arranged in a bucker provided with a ring-shaped cover plate at the other end thereof, so as to form the propulsion device. By utilizing the rotator to rotate in the bucker, the fluid can be driven to rotate; and by utilizing the centrifugal movement generated by the liquid rotation, the fluid pressure which is originally balanced on the round disc is separated, so as to achieve the effect on increasing the pushing power of the propulsion device.

Description

The fluid centrifugal propellor

[affiliated technical field]

The utility model relates to a kind of mechanical device.Be a kind of liquid propeller that separates flat constant force specifically.

[background technology]

In the air or the aircraft institute general-duty propeller in the water, be to arrange fluid by propeller blade to produce thrust at present.This screw propeller can only produce a kind of thrust at work, is the antagonistic force of fluid to blade.If utilize the propelling unit of the centrifugal propelling unit of fluid, the thrust that can produce when it arranges fluid except blade at work, can also produce a thrust again as aircraft.

[summary of the invention]

The utility model provides a kind of propelling unit, and this propelling unit increases than present general-duty propeller thrust, and mechanical efficiency improves.The utility model is achieved through the following technical solutions: a rotor that is made of blade, disk, axle, being contained in one one end opens wide entirely, form mechanical device in the drum shape case of one end by annular cover plate, one end of axle is vertically fixed on disc centre, be fixed with blade on the axle, blade is vertical with disk.Drum shape case is to be fixed on the aircraft, and power machine is installed in the aircraft, and the transmission shaft of power machine is connected with rotor shaft.Rotor is mounted in the drum shape case, and rotor has an end of disk to be contained in worn-out mouthful of end of drum shape case, and is in case with interior position.The other end of rotor is contained in the annular cover plate, between blade and cover plate the microclearance is arranged, and rotor shaft stretches out outside the case and is connected with the power machine transmission shaft.

Is example with this device as the propelling unit of ship, and its principle of work is described, this device is mounted in fixed position on the ship, and the rotor in the case can only rotate in case, can not translation.When rotor rotated in case, the fluid that the blade of rotation drives in the case was done the circumference rotation, and the fluid of high-speed operation produces centrifugal displacement, and this just makes the disk inner face lose fluid, has also just lost the application force of fluid to the disk inner face.But the fluid of disk outside still exists the application force of disk outside, like this, the suffered fluid force in the about two sides of disk is not just being equalled perseverance, if the rotating speed of rotor reach a certain height, can be similar to and think, fluid is zero to the application force of disk the inside, and the fluid pressure that the disk outside is subjected to still exists, direction is pointed to the service direction of ship, and the fluid that its size equals the disk outside multiply by the area of disk to the pressure of disk.

Because drum shape case one end opens wide entirely, the other end has annular cover plate, and the fluid of high speed revolution is squeezed, and can only overflow from the end that case opens wide.Fluid in the case to the pressure of case the inside greater than the fluid of case outside pressure to the case outside.The fluid pressure that the annular cover plate inner face is subjected to equals the fluid pressure of annular cover plate area multiplication ring female cap plate inner face, the fluid pressure of annular cover plate outside equals the fluid pressure of annular cover plate area multiplication ring female cap plate outside, and the difference that the fluid pressure that the annular cover plate inner face is subjected to deducts the fluid pressure that is subjected to outside the annular cover plate just equals another thrust that aircraft is subjected to.Its direction is pointed to the service direction of ship.

Like this, the centrifugal propelling unit of the fluid in the work will be to ship two thrusts simultaneously, i.e. the fluid pressure that is subjected to of the fluid pressure that is subjected to of disk outside and annular cover plate inner face.The fluid pressure that the disk outside is subjected to will be big more and big more with the degree of depth that this device is under water.The annular cover plate inner face is subjected to the pressure of fluid, and the quality that arranges fluid with blade is directly proportional.

When the blade of centrifugal liquid propeller rotor drove fluid and rotates, drum inner fluid pressure increased, and the fluid that increases pressure can only be that direction behind the ship flows out from the case open end, and fluid promptly is the thrust that ship is subjected to the antagonistic force that annular cover plate produces.Its size, the quality that arranges fluid with blade is directly proportional.If peculiar to vessel is present general-duty propeller, the fluid that screw propeller arranges also be to the ship rear to outflow, fluid is the thrust that ship is subjected to the antagonistic force that propeller blade produces.Its size arranges how much being directly proportional of fluid mass with screw propeller.This just explanation, under equal power situation, the thrust of general-duty propeller generation at present, it only is approximately equal to the thrust that centrifugal liquid propeller annular cover plate produces, the thrust that centrifugal liquid propeller produces is greater than the thrust of general-duty propeller generation at present.

During centrifugal liquid propeller device busy, fluid is rotated discharge in case, and it will produce biasing force to sail body as the autogyro screw propeller.Address this problem, two such propelling units can be installed on aircraft at least work simultaneously, turning to of the rotor of these two propeller systems should be opposite.

[embodiment]

Is example with the utility model as the propelling unit of ship, is described with reference to the accompanying drawings concrete device of the present utility model and service condition.Case (1) is fixed in the stern water, and case (1) opening end is towards the stern direction.Axle (4) is vertically mounted on the center of disk (2), blade (3) is fixed on the axle (4), blade (3) is vertical with disk (2) and fix.The rotor that disk (2), blade (3), axle (4) are formed is put in the case (1), disk (2) is in the opening end of case (1), blade (3) is contained in the annular cover plate (5), between blade (3) and the annular cover plate (5) microclearance is arranged, axle (4) stretches out from annular cover plate (5) middle and and propeller shaft couplings.

Accompanying drawing 3 represents that this device is immersed in the water when not working, the inside and outside water of device all is flat permanent to installing inside and outside pressure.Fig. 4 represents that rotor shaft (4) is rotating, and drives blade (3) and disk (2) and rotates together, and the water in the case also and then rotates.This just makes the centrifugal displacement of water generates of disk (2) inner face, and loses water, and the inside and outside surface pressure of disk (2) is no longer flat permanent, and the water of disk (2) outside becomes thrust to ship to the pressure of disk (2) outside.The water of the interior high speed revolution of case (1) becomes greatly the pressure of annular cover plate (5), and the pressure that is subjected to water outside annular cover plate (5) is interior is just no longer flat permanent, and annular cover plate (5) inner face is subjected to the pressure of the pressure of water greater than the water that is subjected to outside the annular cover plate (5).Water is consistent with the service direction of ship to the pressure direction of annular cover plate (5) inner face, becomes the thrust to the shipping row.

When from above-mentioned, this device busy being described, advancing of ship produced two thrusts simultaneously.
