Marine Propeller Control Method Or System.
Jul 14, 2018

Marine propeller control method or system 1. Propeller turning device The propeller turning device includes an upper bracket, a lower bracket, an intermediate shaft, and a nut. The intermediate shaft is fixedly connected with the lower bracket by a bottom portion thereof, and the upper portion of the intermediate shaft is formed into a wedge shape and is provided with a thread on the round surface. The thread is matched with the nut, and the top end and the bottom end of the intermediate shaft are respectively provided with upper lifting ears and lower portions. a lug, the middle portion of the upper bracket is provided with a forming ring hole matching the wedge portion of the intermediate shaft, and the upper bracket is formed with a wedge-shaped portion of the intermediate shaft with the forming ring hole, and the nut is screwed on the intermediate shaft and passes through The washer is pressed against the upper bracket to form a propeller turning device. After the propeller is installed in the upper and lower brackets, the nut is pressed tightly, and the sling does not contact the propeller when lifting the turning body, completely eliminating the damage to the blade and the sling cutting, changing the original spiral will turn over The hoisting method is an innovative technological transformation of the blade turning over. It has a strong practical value for mass shipbuilding and professional shipbuilding. 2. Control method and control system for controllable pitch marine propeller A method for controlling the controllable pitch marine propeller pitch of an engine having an engine includes the following steps: providing a power stop mode to rapidly reduce the ship speed as the vessel advances; The propeller pitch is adjusted to a fully retracted position, while engine power is available throughout the entire process of the vessel transitioning from forward motion to reduced vessel forward speed. The present invention also discloses a system for controlling a controllable pitch marine propeller pitch of a vessel including an engine, comprising: a drive actuator movable from a forward position to a reverse position; a controller for adjusting a pitch of the propeller so that The pitch is in a fully retracted position; and wherein the controller determines the power stop demand by monitoring the movement of the actuator, and is used to adjust the propeller pitch to the fully retracted position according to the determination of the power stop, while the engine power is shifted from the forward movement of the vessel to The entire process of vessel deceleration is available. 3. A propeller lifting and reversing device A propeller lifting and reversing device, the propeller is connected with the lower end of the lifting rod, the lifting rod is arranged in the rotating sleeve, and the lifting rod and the rotating sleeve are arranged in the following manner: The rotating sleeve moves up and down, and the lifting rod and the rotating sleeve cannot rotate with each other, and the rotating sleeve is disposed in the fixing sleeve at the stern, and the upper end of the rotating sleeve protrudes from the fixing sleeve, and is arranged on the rotating sleeve protruding from the fixing sleeve portion. There is a steering rod connected to a piston rod of a hydraulic cylinder fixed at the stern, and the upper end of the lifting rod is connected to the piston rod of another hydraulic cylinder fixed on the rotating sleeve through the connecting bracket. The utility model has the advantages that the propeller lifting and reversing device can quickly lift and reverse the propeller, and remove the garbage or debris wrapped around the propeller, and the operation is convenient, the degree of mechanization is high, and the normal navigation of the water surface clean collecting ship is ensured. And homework. 4. Control method and control system for controllable pitch marine propeller A method for controlling a pitch of a controllable pitch marine propeller including a vessel of an engine, comprising: providing a ship speed indication; according to any one or more parameters selected from the following parameters The ship's speed is used to control engine power. These parameters include: propeller pitch and vessel operating mode. A system for controlling a controllable pitch marine propeller pitch of a vessel including an engine, comprising: means for providing a speed indicating a speed of the ship; and for using the output according to any one or more parameters selected from the following parameters Controllers that control engine power, including: propeller pitch and vessel operating mode. 5. Method and apparatus for actively controlling the propeller thrust pulsation of a boat. A method and apparatus for actively controlling the propeller thrust pulsation of a boat, measured by an axial thrust or axial vibration measuring system mounted on the boat propulsion shafting The pulsation of the axial thrust of the boat propeller or the magnitude of the axial vibration of the propulsion shafting. According to the axial thrust of the boat propeller or the axial vibration of the propulsion shafting, the thrust pulsation controller calculates the need to eliminate the thrust pulsation in the ship. The amount of control force exerted on the boat's propulsion shaft, and then the signal from the thrust pulsation controller is amplified by the power amplifier, and then passed through a non-contact electromagnetic force actuator mounted on the boat's propulsion shafting. The required axial control force is generated to control and compensate the ship's propeller thrust pulsation, thereby reducing the ship


The influence of the propeller propulsive force pulsation on the vibration of the boat.
