Abstract

The invention discloses an integrated water jet propulsion system. The system comprises a water inlet system, a control system and a drainage system. The water inlet system comprises a water suction port, a water suction turbine, a submersible motor, a pressurizing paddle and a main duct. The water suction port is formed in the front end of the main duct. The water suction turbine is arranged in the water suction port in the front end of the main duct. The pressurizing paddle is arranged in the main duct. The submersible motor is a double-output submersible motor and is installed between the water suction port and the front end of the main duct through a support, and the output ends at the two ends of the submersible motor are connected with the water suction turbine and the pressurizing paddle respectively. The drainage system comprises a tail water spraying opening and a flow guide ring arranged in the tail water spraying opening, and the tail water spraying opening is fixed to the tail portion of the main duct. The control system comprises a low-speed motor, a gear set, a controller and a storage battery which are arranged in a cavity. By means of the structure, the phenomenon that the jet flow diffuses around is eliminated, the sprayed jet flow is fully utilized, and more energy-saving, environment-friendly and efficient propelling is achieved.

Description

technical field [0001] The invention relates to the field of marine equipment, in particular to a propeller, in particular to an integrated water jet propulsion system. Background technique [0002] A propeller is a device on a ship that generates kinetic energy. The propeller propeller is the most common type of propeller. The propeller is installed on the propulsion shaft below the waterline at the stern of the boat. The main engine drives the propulsion shaft to rotate together. The reaction force of the water propels the boat forward. Because traditional propellers require a spindle with excellent mechanical properties, they have extremely high requirements on the manufacturing process of the spindle. The transmission efficiency of the mechanical spindle is low, and a large amount of oily lubricant is used, which will cause serious environmental pollution problems. [0003] In recent years, a new type of water jet propeller has emerged. The water jet propeller is a ki...
