Marine bubble resistance reduction device with water inlet flow channel

The marine bubble resistance reduction device is arranged on the outer surface of a ship body and comprises a bulge, an air inlet mechanism and the water inlet flow channel, the bulge is installed on the upper portion of the front end of the bubble resistance reduction device, has a streamline appearance and protrudes downwards, and the bulge comprises a wave rider shell, an upper structure and a cavity. The waverider shell and the upper structure form a cavity, an air nozzle of an air inlet mechanism is installed on the waverider shell, the air nozzle sprays air provided by an air supply system in the ship into the water inlet flow channel for air-liquid mixing to form microbubbles, the microbubbles are sprayed out through the air-liquid nozzle, and a continuous bubble layer is formed at the bottom of the ship shell. Aiming at the current situation that the energy efficiency of the current ship is difficult to improve by the increasingly stringent emission regulations, the bubble resistance reduction device
