Feedback device for side propeller

Abstract

The invention relates to a feedback device for a side propeller. The end part of a propeller shaft is provided with a bearing block, a base above the propeller shaft is fixedly provided with a guide rod, the guide rod is sheathed with a sliding block, one end of the sliding block is fixedly connected with the bearing block, the other end of the sliding block is hinged with one end of a first connecting rod, the other end of the first connecting rod is hinged with a first crank, the first crank is fixedly connected with a lower bar, the lower bar is rotatably and freely supported onto the base, the lower bar is connected with an upper bar, the upper bar is rotatably and freely supported onto a rack, a second crank is fixedly connected with the upper bar, the second crank is hinged with one end of a second connecting rod, the other end of the second connecting rod is hinged with a third crank, the second crank and the third crank are parallel and equal, the third crank is fixedly connected with a projecting shaft of a potentiometer, the projecting shaft of the potentiometer is fixedly provided with a pointer, and the pointer is opposite to the potentiometer. According to the feedback device disclosed by the invention, one slider-crank mechanism and one parallel double-crank mechanism are utilized for converting the rotation angle of a crank disc into the reading of a dial plate, the feedback accuracy is improved, and mounting and debugging are convenient.

Description

technical field [0001] The invention relates to a marine adjustable pitch lateral thruster, in particular to a feedback device of the lateral thruster. Background technique [0002] The adjustable pitch side thruster is to change the thrust magnitude and direction of the side thruster by changing the pitch angle of the blade through the hydraulic system without changing the motor speed and rotation direction. There is a rotating blade mechanism in the hub body of the adjustable pitch lateral propeller, which changes the reciprocating linear motion from the power cylinder into the circular motion of the blade turning. The feedback mechanism converts the rotation angle and direction of the blade into electrical signals through a series of transformations. [0003] Existing feedback is applied to marine adjustable pitch lateral propellers, which is a technology that expresses the rotation angle of the propeller blade through a mechanical device, and through a series of transfo...
