Fig. 2 is lateral plan embodiment illustrated in fig. 1.
Fig. 3 is action schematic diagram embodiment illustrated in fig. 1.
Fig. 4 is action schematic diagram embodiment illustrated in fig. 1.
Figure 5 shows that the structural representation of the embodiment of the present invention two.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.
Embodiment one
Fig. 1 is the structural representation of ship propeller of the present invention, and hull is extended with power take-off shaft 1 backward, and the outer hull of all sides of described power take-off shaft is provided with four hold-down arms 2, and four described hold-down arms are parallel to be arranged in the same way with power take-off shaft; Rib arm 3 is connected with, to strengthen the intensity of single hold-down arm between adjacent two hold-down arms;
Propelling unit 4, be made up of axle and two screw propellers be arranged on axle, the front end of angle of rake axle is connected by joint coupling 8 with described Power output shaft rear end; Coaxially be covered with tubbiness fairing 5 outward at described screw propeller, fairing 5 by support installing on the axle of thruster;
One hanging stick 6, is movably connected in above fairing back segment and between upper support arm; Bulb shape can be arranged in the two ends of described hanging stick, then coordinates bowl-shape adaptor union to be connected on hold-down arm and fairing, can make propelling unit can at the driving lower swing of pendulous device like this.
Pendulous device 7; Be connected between side, fairing rear end and a side support arm; Wherein, described pendulous device can drive propelling unit to move in the horizontal direction.
Fig. 2 is to Figure 4 shows that side diagram embodiment illustrated in fig. 1 and action schematic diagram.As can be seen from Fig. 3 and Fig. 4, because hanging stick is movably arranged on the hold-down arm of top, therefore, under the effect swinging executive device 7, propelling unit afterbody to the left or right side deflection, thus can change the water outlet direction of water outlet, change nyctitropic object to reach.
Wherein, it can be mechanical or fluid pressure type for swinging executive device 7, mechanical is that the rotary motion of original rudder is become hunting motion, like this when the steering wheel on ship turns to, pass through connecting rod swing, thus drive angle of rake rear end to depart from the axial line of power take-off shaft, to change water outlet direction, thus reach the object changing hull direct of travel.
In order to reduce the process of noise spinner case surface rubber coating further, effectively reducing noise radiation unofficial biography, strengthening disguised.
The propelling unit of the present embodiment can be applicable to various water surface ship.
Embodiment two
Fig. 5 is the schematic diagram of another embodiment of ship propeller of the present invention.
In the present embodiment, hanging stick 6 is changed into the second pendulous device 9, first pendulous device 7 and the second pendulous device 9 adopt hydraulic actuating cylinder, and wherein, the first pendulous device 7 is for the driving of horizontal direction, second pendulous device 9 is for the driving of above-below direction, two combineds action to change the water outlet direction of propelling unit tail end, thus reach the object that hull changes multiple directions, therefore, the propelling unit of the 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, on existing waterborne, submarine navigation device, use noise reduction clearly, be a kind of Novel propeller.Novel propeller has powerful propulsive force, improves a lot than traditional propeller, effectively reduces the degradation of energy of propeller current, saving fuel.The propeller shaft rotating speed that cardan shaft, axle revolution ratio are traditional under water can reduce by more than 40 percent, in order to reduce the process of noise spinner case surface rubber coating further, effectively reduces noise radiation unofficial biography, strengthens disguised.
The present invention is a multi-function propeller, no matter do not limit to above-mentioned embodiment, method does any structural change in shape at it, all should think and drop within scope.
