摘要: Disclosed are a method of controlling an underwater thruster, an underwater thruster and a computer-readable storage medium. The control method includes: obtaining a current control parameter and/or a motor control parameter corresponding to an ultra-high power mode when entering the ultra-high power mode; and controlling an operating current of the underwater thruster according to the current control parameter, and/or controlling motor revolutions of the underwater thruster to rotate in a preset mode according to the motor control parameter to control the underwater thruster to operate in the ultra-high power mode. By providing the ultra-high power mode on the underwater thruster, the underwater thruster can output ultra-high power, overcome the problem of slow uplift due to the influence of water flow resistance in the process of underwater operation, and achieve the effect of enhancing the uplift speed.

摘要: A water jet propulsion boat includes a hull, a drive source, a power storage, a jet propulsion mechanism, a power generator, and a controller. The hull includes a water inlet, a jet outlet, and a flow path connecting the water inlet and the jet outlet and including at least a main flow path extending from the water inlet to the jet outlet. The drive source is located in the hull, and the power storage supplies power to the drive source. The jet propulsion mechanism includes an impeller in the main flow path and driven by a driving force of the drive source to generate a water flow to generate a propulsive force to the hull. The power generator is located in the flow path and uses the water flow generated by the impeller to generate power. The controller charges the power storage with the power generated by the power generator.

摘要: A waterborne vessel includes a hull structure, longitudinal and transverse drive tunnels, and one or more thrusters. The hull structure has a base and side walls forming a U-shaped cross-section, open forward and aft ends, and an open top. The drive tunnels extend through the base portion of the hull structure. Each thruster is located at a corresponding intersection of longitudinal and transverse drive tunnels. Each thruster drives water flow through the corresponding drive tunnels and is rotatable about a vertical axis among multiple different thruster orientations in which the thruster drives water flow in one direction or the other through the corresponding longitudinal or transverse drive tunnel. A method includes: lowering the vessel through water to a submerged target payload; maneuvering the vessel and/or payload to position the payload on the hull structure between the side walls; and raising the vessel and payload toward the water surface.

摘要: An energy efficient ship is achieved by powering the ship using at least one propulsion level, each propulsion level having large grids at the forward and stern ends of the ship and side channels incorporating turbines that move water through the ship, rather than around the ship, thereby substantially eliminating energy wasting wakes and cavitation.

摘要: An underwater thruster with improved guide stability and increased kinetic energy utilization rate comprises a power part and a propeller, wherein the power part is provided upstream of the propeller for driving the propeller to rotate. The underwater thruster further comprises a diversion part which is provided between the water inlet part and the water outlet part and is connected with the water inlet part and the water outlet part respectively in a plug-in manner, to uniformly disperse water entering the water inlet part to blades of the propeller.

摘要: A jet pump assembly includes a marine engine, a jet drive and a shield adapted to be secured to a transom of a watercraft. The shield has arms to which the marine engine is secured and legs to which the jet drive is secured, the arms and legs extending in opposite directions. The shield has a flange adapted to be secured to the transom of the watercraft. The shield covers an opening in the transom through which the jet pump assembly is passed during assembly. A gasket between the shield and transom prevents water from entering the watercraft.

摘要: A personal watercraft comprises a deck having coupled thereto a hull defining a bottom wall, a rear wall and a water intake extending from the bottom wall to the rear wall, and a jet propulsion system. The jet propulsion system comprises a housing coupled to the rear wall and defining an inlet to receive water from the water intake, a venturi, and an outlet to expel the water, and comprises a rim-driven motor disposed within the housing between the inlet and the venturi. The rim-driven motor defines a center axis and comprises a stator coupled to the housing, a rotor disposed radially inwardly of the stator relative to the center axis, and impeller blades coupled to the rotor and projecting towards the center axis, the rotor and the impeller blades rotatable about the center axis to draw the water via the inlet and expel the water via the outlet.

摘要: A water-jet propulsion unit includes a body, an impeller for moving water, the impeller disposed in an impeller tunnel, an impeller shaft for driving the impeller, a first bearing housing to support the impeller shaft on the body, and a jet nozzle for forming a water jet. The body comprises a shaft opening for the impeller, a flow duct having a first contact surface, an inlet opening, and an outlet opening, the planes of which are at an angle α relative to each other. The impeller tunnel has a first end comprising a planar second contact surface and a second end comprising a planar third contact surface to seal the impeller tunnel between the body and the jet nozzle. The second and third planar contact surfaces of the impeller tunnel are arranged at an angle relative to each other. The impeller shaft is adapted for alternative types of installation by turning the impeller tunnel through 180° about the rotational axis of the impeller shaft. Support equipment supports the impeller shaft on the body in the alternative positions.
