Abstract
A nozzle-submerged water jet propeller capable of backing and a working method thereof belong to the field of water jet propulsion. The impeller comprises an impeller, blades arranged on the impeller and an impeller driving motor, and is characterized in that the impeller driving motor is a forward and reverse running motor, and a blade angle regulator is arranged in the impeller. When the water jet propulsion device operates in the forward direction, the motor operates in the forward direction and the reverse direction, the angle of the impeller blade is kept unchanged, and the ship sails in the forward direction. When the ship runs in the reverse direction, the forward and reverse running motors rotate reversely, the impeller blades rotate 180 degrees through the blade angle regulators, and the ship can reverse. The invention gets rid of the current situation that backing can be realized only by a backing device originally, saves a large space for the ship and lightens the weight of the ship; meanwhile, the hydraulic control system is removed, and the structure of the whole water jet propulsion device is greatly simplified.
