Wherein, to drive propelling unit circumferentially mobile for described first pendulous device and the second pendulous device combined action.
Preferably, described propelling unit is made up of the plural paddle of axle and coaxial setting.
Preferably, described propeller shaft is provided with fairing, is coated with rubber layer at described fairing.
Among above-mentioned the present invention, utilize pendulous device, can change angle of rake water outlet direction, thereby can directly drive hull under the situation that does not need rudder turns, to form a kind of propelling unit of brand new, this propelling unit directly can be turned simultaneously, thereby has reduced turn radius.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention one.
Fig. 2 is lateral plan embodiment illustrated in fig. 1.
Fig. 3 is action scheme drawing embodiment illustrated in fig. 1.
Fig. 4 is action scheme drawing embodiment illustrated in fig. 1.
Figure 5 shows that the structural representation of the embodiment of the invention two.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
Embodiment one
Fig. 1 is the structural representation of ship propeller of the present invention, is extended with power take-off shaft 1 on hull backward, is provided with four hold-down arms 2 at the outer hull of all sides of described power take-off shaft, and described four hold-down arms are parallel to be arranged in the same way with power take-off shaft; Be connected with rib arm 3 between adjacent two hold-down arms, to strengthen the intensity of single hold-down arm;
One hanging stick 6 is movably connected between fairing back segment top and the top hold-down arm; The bulb shape can be arranged in the two ends of described hanging stick, cooperates bowl-shape adaptor union to be connected on hold-down arm and the fairing then, can make the propelling unit can be at the driving lower swing of pendulous device like this.
Fig. 2 is to Figure 4 shows that side diagram embodiment illustrated in fig. 1 and action scheme drawing.From Fig. 3 and Fig. 4 as can be seen since hanging stick be movably arranged on the top hold-down arm on, therefore, under the effect of swing executive device 7, the propelling unit afterbody can be to the left or right side deflection, thereby can change the water outlet direction of water outlet, to reach the purpose that changes direction.
Wherein, swing executive device 7 can be for mechanical or fluid pressure type, mechanical is that rotatablely moving of original rudder become hunting motion, like this when the direction machine on the ship turns to, pass through connecting rod swing, thereby drive the axial line that power take-off shaft is departed from angle of rake rear end, with change water outlet direction, thereby reach the purpose that changes the hull direct of travel.
Handle with rubber coating in order further to reduce noise spinner case surface, effectively reduce the noise radiation unofficial biography, strengthen disguised.
The propelling unit of present embodiment can be applicable to various water surface ships.
Embodiment two
Fig. 5 is the scheme drawing of another embodiment of ship propeller of the present invention.
In the present embodiment, changed hanging stick 6 into second pendulous device 9, first pendulous device 7 and second pendulous device 9 adopt hydraulic actuating cylinder, and wherein, first pendulous device 7 is used for the driving of horizontal direction, second pendulous device 9 is used for the driving of above-below direction, two combineds action to be changing the water outlet direction of propelling unit tail end, thereby reach the purpose that hull changes a plurality of directions, therefore, the propelling unit of present embodiment can be applicable to various submersible vessels, as Submarine etc.
In summary, the invention provides a kind of energy-saving fuel, increase the speed of a ship or plane, quick steering, effectively reduce noise ability, existing waterborne, submarine navigation device uses noise reduction very obvious, is a kind of novel propelling unit.Novel propelling unit has powerful propulsive force, improves a lot than traditional propeller, effectively reduces degradation of energy, the saving fuel of propeller current.Cardan shaft, the traditional propeller shaft rotating speed of axle revolution ratio can reduce more than 40 percent under water, handle with rubber coating in order further to reduce noise spinner case surface, effectively reduce the noise radiation unofficial biography, strengthen disguised.
The present invention is a multi-function propeller, does not make any structure in shape at it and changes no matter do not limit to above-mentioned embodiment, method, all should think and drop within the protection domain of the present invention.
