Detailed Description
The invention will be described in detail below with reference to the following figures: the blade rotating device for the adjustable propeller mainly comprises a propeller body, wherein the propeller body consists of a propeller shaft and an inner oil pipe arranged in the middle of the propeller shaft, and is characterized in that one end of an outer sleeve 2 is arranged between the propeller shaft and the inner oil pipe, the outer sleeve can horizontally move in the propeller shaft, the other end of the outer sleeve is provided with an inner sleeve 3, the inner sleeve 3 is sleeved between the outer end of the inner oil pipe and the outer sleeve, the inner sleeve 3 moves back and forth under the driving of the movement of the inner oil pipe of the adjustable propeller, so that the outer sleeve 2 moves back and forth in the propeller shaft, a first oil inlet is formed in the upper part of the outer sleeve 2, and a second oil inlet is formed in the rear end of the inner sleeve 3. The inner sleeve 3 is fixedly connected with the outer sleeve 2 through a nut 5, the inner sleeve 3 is connected with the inner oil pipe through threads, the outer sleeve 2 is sealed with the propeller shaft through a sealing ring 1, and the inner sleeve 3 is sealed with the outer sleeve through a sealing ring 4
The left end of the inner sleeve is connected with an inner oil pipe of the adjustable paddle through threads, and the horizontal movement of the inner oil pipe of the adjustable paddle drives the inner sleeve to move back and forth, so that the outer sleeve moves back and forth in the central hole of the paddle shaft. Oil is fed from a joint at the upper part of the outer sleeve, pressure oil enters a front oil cavity of a propeller hub oil cylinder at the rear end of the propeller shaft through a middle hole of the propeller shaft, a piston is pushed to move backwards, and then a crank mechanism in the propeller hub drives the blades to rotate in the positive direction and simultaneously drives the outer sleeve to move backwards; on the contrary, oil is fed from the right end joint of the inner sleeve, pressure oil enters the rear oil cavity of the propeller hub oil cylinder through the inner sleeve and the inner oil pipe, the blades are driven to rotate in the opposite direction, and the outer sleeve moves forwards.
Example (b): the invention mainly comprises a sealing ring, an outer sleeve, an inner sleeve, a nut and a joint. The left end of the outer sleeve is arranged in the paddle shaft, dynamic sealing is achieved through the sealing ring, and the outer sleeve can horizontally move in the paddle shaft; the inner sleeve is fixed in an inner hole of the outer sleeve through a nut and a sealing ring, the left end of the inner sleeve is connected with an inner oil pipe of the adjustable paddle through threads, and the horizontal movement of the inner oil pipe of the adjustable paddle drives the inner sleeve to move back and forth, so that the outer sleeve moves back and forth in a central hole of the paddle shaft. When the paddle needs to rotate forwards, the hand pump is connected with the joint at the upper part of the outer sleeve through the rubber pipe, and pressure oil enters a front oil cavity of the oil cylinder of the paddle hub to push the piston to move backwards; when the paddle needs to be rotated reversely, the hand-operated pump is connected with the connector on the right side of the inner sleeve through the rubber tube, and pressure oil enters the rear oil cavity of the paddle hub oil cylinder to push the piston to move forwards.
