Abstract
The invention discloses a paddle wheel for a paddle wheel ship, which comprises a wheel shaft, a wheel hub arranged around the wheel shaft, and paddles which are uniformly arranged on the outer edge of the wheel hub, wherein the water-repelling surface of the paddle is formed by at least two flat surfaces or camber surfaces which are connected with each other or by a flat surface and a camber surface which are connected with each other; and the water-repelling surface of the paddle deflects to the rotating direction of the paddle wheel from the outer edge to the inter edge, with the defection angle Alpha larger than 10 degrees and less than 120 degrees. The invention has the advantages that the energy waste during the high-speed rotation of the paddle wheel is avoided, the water-repelling surface of the paddle deflects to the rotating direction of the paddle wheel from the outer edge to the inter edge by 10 degrees to 120 degrees, so when the paddle repels water, the movement direction of water body flying off upward can be changed, and an extra upward counter acting force can be obtained, so the useful work is increased, and the idle work can be reduced, thus realizing the improvement of propulsive efficiency of the paddle wheel when in high-speed rotation.
Description
Technical field
The present invention relates to paddle steamer, especially relate to the paddle wheel that is used for paddle steamer.
Background technology
The paddle wheel that the tradition paddle steamer uses, its blade is slab construction.When the paddle wheel low speed rotation, the entry stroke of blade is to clap water state downwards, and the water outlet stroke of blade is the state that upwards pumps up water, and the idle work ratio of two states is all bigger, thereby has wasted a large amount of kinetic energy; So the propulsion coefficient during the paddle wheel low speed rotation is very low.When the paddle wheel high speed revolution, the entry stroke of blade is to clap water state downwards, and the major part of being clapped water body flies out downwards, and paddle wheel obtains antagonistic force upwards, is used to support the gravity of hull, is useful work; The fraction of being clapped water body upwards flies out, and is idle work, thereby has wasted a small amount of kinetic energy; State during the blade water outlet is idle running, because blade drying this moment water body in front has been drained; So, though the propulsion coefficient height of the propulsion coefficient during the paddle wheel high speed revolution during than low speed rotation, but still undesirable.
Summary of the invention
The high paddle wheel that is used for paddle steamer of propulsion coefficient when the object of the invention is to provide a kind of high speed revolution.
For achieving the above object, the present invention can take following technical proposals:
The paddle wheel that is used for paddle steamer of the present invention, by wheel shaft, around described wheel hub of taking turns axle mounting, the blade that radial equipartition is arranged on the described wheel hub outer rim is formed; The drying face of described blade is made of interconnective two planes or cambered surface or interconnective plane and cambered surface at least, the drying face of described blade from the position, outer to interior along the position to the deflection of paddle wheel hand of rotation, deflection angle a is greater than 10 degree, less than 120 degree.
Described cambered surface is an arc surface.
Described cambered surface is an elliptical arc surface.
Described cambered surface is the parabola cambered surface.
The outer of described drying face and the end face of blade are or/and the end face of the interior edge of drying face and blade is an acute angle.
The invention has the advantages that and avoid the energy dissipation of paddle wheel when high speed revolution, the drying face of blade is spent to paddle wheel hand of rotation deflection 10 degree～120 along the position to interior from the position, outer, therefore changed the sense of motion of the water body that upwards flies out during the blade drying, obtain an extra upward reaction force, to increase useful work, reduce idle work, thus the propulsion coefficient when realize improving the paddle wheel high speed revolution.

Fig. 2 is the structural representation that blade drying face of the present invention is made of three planes.
Fig. 3 is that blade drying face of the present invention is the structural representation of cambered surface.
Fig. 4 is the structural representation that blade drying face of the present invention is made of plane and cambered surface.
The specific embodiment
As shown in Figure 1, the paddle wheel that is used for paddle steamer of the present invention, by wheel shaft 1, around the wheel hub 2 that described wheel shaft 1 is installed, six blades 3 that radial equipartition is arranged on described wheel hub 2 outer rims are formed; The drying face 4 of described blade 3 is made of interconnective two planes, the drying face 4 of described blade 3 from the outer 5 positions to interior along 6 positions to the deflection of paddle wheel hand of rotation, deflection angle a be 60 the degree; The outer 5 of described drying face 4 and the end face of blade 3, interiorly be acute angle with the end face of blade 3 along 6.As shown in Figure 2, the drying face 4 of described blade 3 also can be made of three planes.As shown in Figure 3, the drying face 4 of described blade 3 also can be cambered surface.As shown in Figure 4, the drying face 4 of described blade 3 also can be made of plane and cambered surface.
