A main bracket is arranged in a shell; a main motor is arranged on the main bracket; a double ejector rod hydraulic cylinder is arranged on the main bracket; one end of the piston rod of the main bracket is connected with a swing dial; the swing dial is fixed with the outer ring of a bearing and is connected with the main bracket; a rotating wobble plate is fixed with the inner ring of the bearing and is connected with a pin roll; a front supporting sleeve is fixed with the inner ring of the bearing; the main bracket is fixed with the outer ring of the bearing and the outer ring of an electric slip ring; an impeller shaft is fixed with the inner ring of the bearing; an impeller seat is fixed with the outer ring of the bearing; the main motor is connected with a middle shaft; the middle shaft penetrates the inner ring of the electric slip ring; the swing dial, the rotating wobble plate as well as a spherical turning wheel disk and is connected with the front supporting sleeve. The varying pitch propulsion machinery of the underwater moving body leads the swing dial and the rotating wobble plate to be capable of generating any displacement and obliquity in a certain range and leads the pitch angle of each blade to be capable of changing independently, namely, the direction of composite force for leading the blades of a propeller to generate thrust can be changed, thus generating vector thrust.
Description
(1) technical field
The present invention relates to a kind of underwater propulsion unit, particularly a kind of mechanical drive mode of underwater propulsion unit.
(2) background technology
In order to make the object can be, just must give one on object equal with water resistance (or greater than) but the opposite thrust of direction, and propeller blade be exactly the device that other forms of transformation of energy is become this thrust with certain speed at underwater exercise.Screw propeller is to be made up by a group aerofoil to form, and how much variations of aerofoil and the existence of pitch angle make the aerofoil fluid up and down of flowing through that different speed be arranged, and the difference of this speed can cause the difference of aerofoil upper and lower surface pressure, thereby produces thrust (lift).
The pitch of most screw propellers fix promptly usually said spacing oar.The spacing oar is fixed the pitch of each blade, makes the thrust of other directions of blade generation cancel out each other, be merged into along propeller hub axis direction thrust.This spacing oar can only change thrust by changing rotating speed, and can not produce the thrust of other directions.
There is the blade of some screw propellers can utilize transmission device to carry out rotation in the course of the work with respect to propeller hub, pitch that this just changes, thereby be called controllable pitch propeller again, be called for short the displacement oar.For example number of patent application is 98810011.8, and name is called the technical scheme put down in writing in the patent document of " variable pitch marine propeller " (open day a 2000.11.29) etc.But this displacement oar is synchronous to the change of pitch, i.e. the change of the pitch angle of all blades is simultaneously, and it is also identical to change angle.This just makes this displacement oar can change along the size and Orientation of propeller hub axis thrust.Though this displacement oar can change the size of thrust, but still can't produce the thrust of other directions.
(3) summary of the invention
The object of the present invention is to provide a kind of variable-pitch propelling plant of underwater moving body that can change the mechanical drive mode at each screw pitch of propeller blades angle of propelling unit arbitrarily.
The object of the present invention is achieved like this:
