Abstract
The invention relates to a marine variable-paddle-bending-degree propeller which aims at solving the problems that a traditional marine propeller is small in propulsive force, low in propulsive efficiency and not high in maneuverability and no technical schemes for improving the propulsive force and the propulsive efficiency of the propeller by changing the bending degree of the propeller exist. The marine variable-paddle-bending-degree propeller comprises a propeller hub and a plurality of paddles. Each paddle comprises a paddle body, a flap, a second flap driver, a flap fixing rod, a flap push rod and a displacement amplification mechanism. The paddles are evenly and fixedly arranged on the propeller hub in the circumferential direction. A flap installation hole is machined in each paddle body. The flap fixing rods are inserted in the flaps. The two ends of each flap fixing rod are fixedly arranged on the side walls of the corresponding flap installation hole. The displacement amplification mechanisms are arranged on the second flap drivers in a sleeving mode. Each second flap driver is fixedly arranged on the corresponding paddle body in the mode that the second flap driver is close to the corresponding flap installation hole. The marine variable-paddle-bending-degree propeller is used for the field of propeller manufacturing.
Description
Technical field
The present invention relates to the screw propeller that blade camber peculiar to vessel is variable.
Background technology
The Push Technology of marine propeller is the emphasis of science and techniques of defence development always, tradition marine propeller propulsive force is relatively little and propulsion coefficient is relatively low, manoevreability is not high, along with boats and ships are further urgent to the requirement of Push Technology, tradition marine propeller obviously can not reach required performance, therefore needing to carry out improvement to screw propeller to be better propulsion of ship industry service, although a lot of scholar improves for traditional propeller, but because the blade form of screw propeller itself does not change, the Combination property of the screw propeller after improving is not had greatly improved, at present, its propulsive force and the simpler beyond doubt and effective method of propulsion coefficient is improved by changing the camber of screw propeller, prior art does not also improve the method for marine propeller propulsive force and propulsion coefficient by solving problems.
Summary of the invention
Content of the present invention is that traditional marine propeller propulsive force is relatively little and propulsion coefficient is relatively low in order to solve, the problem that manoevreability is not high, and the camber also not by changing screw propeller improves the technical scheme of its propulsive force and propulsion coefficient, and then the screw propeller providing blade camber peculiar to vessel variable.
The present invention is the technical scheme adopted that solves the problem:
The screw propeller that blade camber peculiar to vessel is variable, it comprises propeller hub and multiple blade; Each blade comprises blade body, wing flap, the second flap drive, wing flap fixed link, wing flap push rod, displacement amplifying mechanism; Multiple blade body is along the circumferential direction uniform to be fixedly mounted on propeller hub, each blade body is processed with wing flap mounting hole, each wing flap fixed link is inserted on wing flap, wing flap and wing flap fixed link are interference fit, and the two ends of each wing flap fixed link are fixedly mounted on wing flap mounting hole sidewall, displacement amplifying mechanism is sleeved in the second flap drive, each second flap drive is fixedly mounted on blade body near wing flap mounting hole, and one end of each wing flap push rod is fixedly mounted on displacement amplifying mechanism, the other end of each wing flap push rod withstands on wing flap.
The invention has the beneficial effects as follows: the swing being driven wing flap 3 by the second flap drive 4, the hunting range of wing flap 3 is 20 °, deflection angle when regulation wing flap does not swing is 0 °, the reference angle that this angle swings as wing flap, wing flap is swung to direction, screw propeller blade face and is defined as "+", swing to blade blade back direction and be defined as "-", the deflection angle of wing flap can be made to realize the change of-10 ° ~+10 ° by design, and then realize the change of propeller blade 2 camber, thus realize the change of screw propeller propulsive force, and under different rotating speeds, keep screw propeller all to have relatively higher propulsion coefficient and larger fltting speed and propulsive force, have under maximum speed of revolution and compare the higher fltting speed of similar screw propeller and larger propulsive force, start fast at screw propeller, emergency brake, under the operating mode such as to swerve, there is more stable performance, and then realize screw propeller there is more high maneuverability, when boats and ships are in cruising condition, flap deflection can be made to arrive the most effective situation of propeller works, thus fuel saving, when propeller load is overweight, easily part load can be laid down by changing its camber, while the few damaged of protection screw propeller, also the impact failure brought because of the mode of operation of conversion marine main engine is avoided, the high degree of flexibility of this screw propeller and multi-operation mode will improve its Combination property greatly, it is made more to be adapted to complicated marine environment, for its high efficiency in different situations, large propulsive force, high maneuverability advances and haves laid a good foundation.
