Abstract
The invention belongs to ship's propeller, especially a kind of technical fields of the flat-pushing propeller of high speed displacement rotary vane for displacement rotary vane high-speed thruster.Structure bulky, the revolution of paddlewheel propulsion device be low, blade movement when need to be discharged, enter hydrodynamic(al) work, running resistance is big, easily by many defects such as Lidar Equation.The present invention, for basic prototype, uses displacement rotary vane for thrust power with paddlewheel propulsion device, and it is as follows that major technique improves main points: 1. the installation form of this propeller is full immersion, can effectively eliminate the influence of water surface stormy waves；2. the newly-increased rotating cylinder with T-type groove, and displacement rotary vane is then hidden in the T-type groove of rotating cylinder, the displacement rotary motion that rotary vane is realized stretching under the action of limit track, retracted.Blade pushes away water acting, thrust output when stretching out rotating cylinder groove；When blades retracted rotating cylinder groove, idle return；This technology alteration effectively reduces resistance loss of the rotary vane in return course, and overall structure revolving speed more compact faster, greatly increases fltting speed.
Description
Technical field
The invention belongs to ship's propeller, especially a kind of technical field of the flat-pushing propeller of high speed displacement rotary vane.
Background technique
Present invention combination paddlewheel propulsion device, the flat-pushing propeller of full circle swinging are basic prototype, select displacement rotary vane flat-pushing
For thrust power.Propeller revolving body, in terms of be suitably modified, increase displacement rotary vane restriction track,
And semiclosed propeller housing, mounting means are changed to full immersion hull bottom installation.
Summary of the invention
The main construction of this propeller includes 1. blade, 2. rotating cylinder, 3. limit track, 4. semiclosed as shown in Figure 1:
Shell.
Working principle: blade is made of cuboid plate, both ends position rotating idler wheel, and cuboid plate is mounted on revolving drum
In the T-slot of body.Blade synchronous rotary, blade idler wheel in the case where the rotation of rotating cylinder drives design rail along fixed limit track
Mark rotation, the displacement rotary motion for stretching out, retracting is realized with blade under the collective effect of rotary centrifugal force.Blade stretches out revolving drum
It is effective push acting area segments when body operates, is idle return phase when blades retracted rotating cylinder operates.Six blades are successively
Circulation persistently pushes away water acting and generates continuously-directional thrust.
Mounting means: this propeller is as shown in Figure 2 using installation form:
Entire propeller submerges installation to two side bottom of hull, and the lower section sealing surface of semi-enclosed shell is installed to ship
On body, blade acting area surface is extend out on the outside of hull, and rest part is all on the inside of hull.Such mounting means pushes away blade
Water acting is more smooth, also greatly reduces propeller to the drag effects of hull.Compared with screw propeller, this propeller
Vane stress area it is smaller, the thrust of generation is also small, it is therefore desirable to multiple groups propeller be used in conjunction with could drive ship high speed
Navigation.Propeller is installed and can be arranged along hull two sides length direction, one mountable 8, ship or more propellers.
Product example: structure is complicated for this propeller, and the propeller using effect of small dimension size is not so good as propeller, revolution
Barrel diameter is greater than 1 meter or more has certain advantage just now.The present invention is with 1080 × 1000(mm of rotating cylinder specification φ) be
Example, as shown in Figure 3: the average radius of gyration R of the model propeller effective push blade is 0.55 meter, and rotating cylinder designs revolution
N be 600 revs/min, theoretical calculation effective push blade be averaged rotation speed up to the π of v=2 Rn/60 be 34.54 meter per seconds.Assuming that
It is loaded on the ship of 7 meters of (width) × 35 meter (length), shipped quantity 8, theory can push ship with the speed of 38 nautical miles/hour
Navigation.
The utility model has the advantages that the ship of installation propeller of the present invention, route speed are fast；The power of single propeller is small, is easy real
The automation control of existing all electric propulsion；By controlling direction of rotation and the revolving speed of propeller, the navigation side of ship just can control
To controllability is stronger；Along the equally distributed thrust device of hull surrounding, the influence of water flow can be largely reduced, is increased anti-
Stormy waves ability.
