Claims

[Scope of utility model registration request]

In order to control the blade angle of a variable pitch propeller for propulsion on a ship, an actuator that can move the movable blades of the variable pitch propeller, a fuel supply amount detector that detects the amount of fuel supplied to the main engine, and a load that sets the load on the main engine a setting device; a first comparator that compares the detection signal from the fuel supply amount detector with the load setting signal from the load setting device; an actuator control mechanism that receives power through an input terminal and controls the power supply from the pump to the actuator, and also includes an emergency signal generator that outputs an emergency signal in an emergency, and a rotation speed that detects the rotation speed of the main engine. A detector, a rotation speed setting device for setting the rotation speed of the main engine, and a second comparator for comparing a detection signal from the rotation speed detector and a rotation speed setting signal from the rotation speed setting device, a transmission circuit that transmits a control signal output from the second comparator to the actuator control mechanism via a second input terminal of the changeover switch; and a transmission circuit that is normally closed to the first input terminal. A propeller blade angle control device for a ship, comprising an emergency switch operating mechanism that switches a changeover switch to 0 and to the second input end side when an emergency signal from the emergency signal generator is received.
