Description
Technical field
A kind of two oar square tube marine propeller, relates to a kind of marine propeller, particularly relates to a kind of square tube marine propeller.
Background technology
Traditional band cylinder propeller is columnar, and the plane of rotation of its blade is substantially vertical with the opening direction of shell, and sectional area is comparatively large, and resistance is comparatively large, and especially during high speed, resistance is larger, and owing to adopting single screw propeller, ratchet knob square is large, poor stability.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of resistance less and button square two oar square tube marine propellers of cancelling out each other.
The technical solution of the utility model is: a kind of two oar square tube marine propeller, comprises Left Hand Engine, left handed propeller, right driving engine, right-hand screw oar and square-tube-shaped shell.Left Hand Engine is arranged on outside the left side of square-tube-shaped shell by left socle, and the output shaft of Left Hand Engine is connected with left handed propeller; Right driving engine is arranged on outside the right side of square-tube-shaped shell by right support, and the output shaft of right driving engine is connected with right-hand screw oar.Left Hand Engine is identical with right driving engine.Left handed propeller and right-hand screw paddle structure and measure-alike.Square-tube-shaped shell is surrounded by left plate, top board, right panel and base plate.Left handed propeller and the symmetrical inside being installed on square-tube-shaped shell of right-hand screw oar.The rotational plane of left handed propeller and the rotational plane of right-hand screw oar are less than 160 ° at the angle in front, and the opening of this angle forward.The angle of the rotational plane of left handed propeller and the left plate of square-tube-shaped shell is less than 80 °, and the opening of this angle backward.The rotational plane of left handed propeller is all vertical with base plate with the top board of square-tube-shaped shell.The section of left handed propeller and right-hand screw oar is all aerofoil profile.Square-tube-shaped shell and left handed propeller and right-hand screw oar coordinate compactly, and the minimum clearance between left handed propeller and square-tube-shaped shell is less than 8mm.Left handed propeller and right-hand screw oar are near installing but can not touching.Left handed propeller and right-hand screw oar can rotate neatly respectively under the driving of Left Hand Engine and right driving engine in square-tube-shaped shell, the direction of rotation of left handed propeller and right-hand screw oar, torque of cancelling out each other.
For convenience of controlling party to, the rear end midway location of square-tube-shaped shell is provided with yaw rudder, and the resistance of rear end midway location to incoming flow that yaw rudder is arranged on square-tube-shaped shell is less, and controlling party to effect better.Because current can be extruded from rear end the right and left of square-tube-shaped shell in the combined action of left handed propeller, right-hand screw oar and square-tube-shaped shell.
The utility model a kind of pair of oar square tube marine propeller is work like this: Left Hand Engine drives left handed propeller to rotate, right driven by engine right-hand screw oar rotates, and then extrudes in the water inspiration square-tube-shaped shell in front from the rear of square-tube-shaped shell in the combined action of left handed propeller, right-hand screw oar and square-tube-shaped shell.
The advantage of the utility model a kind of pair of oar square tube marine propeller is: compared with traditional marine propeller, and when flow is identical, the angle of rake basal area of the utility model is much smaller, and efficiency is higher than traditional propeller; When the most outstanding advantage of the utility model propelling unit is high speed, resistance is less.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model a kind of pair of oar square tube marine propeller, and Fig. 2 is the birds-eye view of Fig. 1.In figure: 1 is Left Hand Engine, 11 is the output shaft of Left Hand Engine, and 2 is left handed propeller, 21 path of motions representing the tip of left handed propellers, 3 is right driving engine, 31 is the output shaft of right driving engine, and 4 is right-hand screw oar, 41 path of motions representing the tip of right-hand screw oars, 5 is square-tube-shaped shell, 6 is yaw rudder, the swaying direction of 61 expression yaw rudders, and 7 represent streamlines; In Fig. 1, upper left hollow arrow represents described angle of rake working direction.
Detailed description of the invention
Be illustrated the utility model below in conjunction with accompanying drawing: with reference to accompanying drawing, a kind of two oar square tube marine propeller, comprises Left Hand Engine 1, left handed propeller 2, right driving engine 3, right-hand screw oar 4 and square-tube-shaped shell 5.Left Hand Engine 1 is arranged on outside the left side of square-tube-shaped shell 5 by left socle, and the output shaft 11 of Left Hand Engine is connected with left handed propeller 2; Right driving engine 3 is arranged on outside the right side of square-tube-shaped shell 5 by right support, the output shaft 31 of right driving engine is connected with right-hand screw oar 4.Left Hand Engine 1 is identical with right driving engine 3.Left handed propeller 2 and right-hand screw oar 4 structure and measure-alike.Square-tube-shaped shell 5 is surrounded by left plate, top board, right panel and base plate.Left handed propeller 2 and the symmetrical inside being installed on square-tube-shaped shell 5 of right-hand screw oar 4.The rotational plane of left handed propeller 2 and the rotational plane of right-hand screw oar 4 are 80 ° at the angle β in front, and the opening of this angle β forward.The angle α of the rotational plane of left handed propeller 2 and the left plate of square-tube-shaped shell 5 is 40 °, and the opening of this angle α backward.The rotational plane of left handed propeller 2 is all vertical with base plate with the top board of square-tube-shaped shell 5.The section of left handed propeller 2 and right-hand screw oar 4 is all aerofoil profile.Square-tube-shaped shell 5 coordinates compact with left handed propeller 2 and right-hand screw oar 4, and the minimum clearance between left handed propeller 2 and square-tube-shaped shell 5 is 4mm.Left handed propeller 2 and right-hand screw oar 4 are near installing but can not touching.Left handed propeller 2 and right-hand screw oar 4 can rotate neatly respectively under the driving of Left Hand Engine 1 and right driving engine 2 in square-tube-shaped shell 5, the direction of rotation of left handed propeller 2 and right-hand screw oar 4, torque of cancelling out each other.The rear end midway location of square-tube-shaped shell 5 is provided with yaw rudder 6.
Described propelling unit is work like this: Left Hand Engine 1 drives left handed propeller 2 to rotate, right driving engine 3 drives right-hand screw oar 4 to rotate, and then extrudes in the water inspiration square-tube-shaped shell 5 in front from the rear of square-tube-shaped shell 5 in the combined action of left handed propeller 2, right-hand screw oar 4 and square-tube-shaped shell 5.Steering rudder 6 switch can change the direction of advancing.Because left handed propeller 2 and right-hand screw oar 4 are tilting, water side is little, and resistance is little, and due to the effect of square-tube-shaped shell 5, described propelling unit creates mirrored effect, and there is the insectival urgency of class and open the fluid-mechanical effect with sumo, therefore propulsion coefficient is high.
