Background
With the progress of ocean development technology and the development of ship industry in China, the requirements of China on ship underwater propellers are greatly improved, the traditional underwater propellers are that a motor shaft is provided with a propeller hub, when the motor drives the propeller to rotate, water flows in from the front of the motor, the motor generates head-on resistance on blades, the blade tips of the propeller generate induced resistance and cavitation when rotating, and the efficiency of the propeller is reduced. In addition, because the output shaft of the traditional underwater motor is long in rotation, the propeller can generate radial vibration when rotating, and the efficiency of the whole propeller is reduced. Therefore, the hollow hub propeller comes into force, the mounting mode of the propeller blades of the existing hollow hub propeller is fixedly mounted in the flow guide box of the motor rotor of the hollow hub propeller, and the radial included angle of the blades relative to the motor rotor is fixed, namely the pitch of the propeller is fixed and cannot be adjusted.
In the same-level ship, due to different ship body designs, the matching difference between the helix angle in the propeller and the ship shape is very large, the helix angle is increased, and the pitch is also increased, namely, the same blade changes the helix angle in the propeller, namely, the pitch of the propeller is changed. In the production of products, the design of the spiral angle of the propeller is based on a drawing, the optimal spiral angle is obtained through theoretical calculation, and because the actual ship has errors with the theoretical design, the optimal spiral angle of the actual ship in the driving process cannot be completely matched with the theoretical design, and sometimes the errors are larger. The helical angle of the propeller is large, the torque of the motor is increased, and the motor is easy to block; the helix angle of the propeller is small, and the rated power of the motor cannot be completely absorbed by the propeller, so that reactive power is generated, the working efficiency of the motor is also reduced, and the quality of a power grid in a ship power station is influenced.
Although the problems can be solved by the adjustable propeller, the adjustable propeller mechanism is complex and expensive, and particularly, an inner hole of a motor rotor of the hollow hub propulsion device is a mounting hole of a propeller, so that a blade rotating mechanism for mounting the adjustable propeller is not arranged in a space position.
In addition, the hollow propulsion unit usually, the water conservancy diversion letter in its propulsion motor rotor is the straight letter way, diameter is unanimous around the water conservancy diversion letter promptly, when propulsion motor drove screw during operation, the rivers of intaking through the acceleration back of screw, its play rivers velocity will be improved, because the water conservancy diversion letter intake water yield equals the play water yield, consequently, the export water column of water conservancy diversion letter will be less than the import water column, because the screw is through rotatory inertia, carry rivers away, rotatory rivers flow when being greater than the water conservancy diversion letter of its water column diameter, must produce the inflation, lead to a rivers velocity of flow and water pressure reduction, thereby propulsion efficiency has been reduced.
In summary, the propellers in the motor rotor of the existing hollow propeller are fixedly installed and cannot be changed once being manufactured, so that the shapes of the ships and other manufacturing errors cannot be caused, the propellers cannot be adjusted, the propellers and the shapes of the ships are in one-to-one correspondence, one propeller can only be used by one ship, and the use efficiency and the use range of the propeller are influenced,
