Abstract

The invention discloses an autonomous adjustment method for the immersion depth of a propeller propelling device of an unmanned culture ship, which comprises the following steps: step 1, a propeller propelling device is arranged at the tail part of the unmanned culture ship, the propeller propelling device comprises an immersion rod, a propeller assembly and a lifting driving assembly, the propeller assembly is connected with the bottom of the immersion rod, a lifting driving assembly is arranged on the unmanned culture ship, the power output end of the lifting driving assembly is connected with the immersion rod, the propeller assembly comprises a propeller, a rotating motor and a water depth sensor, and a weighing sensor and a central processing unit are arranged in the unmanned culture ship; step 2, the unmanned culture ship is placed in water, the propeller is driven to rotate by a rotating motor, the water depth sensor is adopted to collect the immersion depth data of the propeller, the weighing sensor is adopted to collect load data of the unmanned culture ship, the immersion depth data and the load data are transmitted to a central processing unit, the central processing unit is adopted to control the lifting assembly to work, and autonomous adjustment of the immersion depth of the propeller propelling device is achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned breeding ships, in particular to a method for autonomously adjusting the immersion depth of a propeller propulsion device of an unmanned breeding ship. Background technique [0002] A marine propeller is a device that converts propeller rotational power into ship propulsion by rotating the blades in the water. The draft of the hull of the ship is different under different loading conditions, and the immersion depth of the propeller will also change. As the load capacity of the ship decreases, the immersion depth of the propeller will also decrease. When it exceeds a certain threshold, the propeller blades will be exposed to the water surface, commonly known as the propeller "out of water". Once the propeller "gets out of the water", its propulsion efficiency will decrease. [0003] At present, the propellers used on ships are generally fixed installations, and the immersion depth of the propell...
