Stabilization device suitable for single-propeller unmanned surveying vessel

Abstract

The invention relates to the technical field of unmanned ships, in particular to a stabilization device suitable for a single-propeller unmanned surveying vessel. The stabilization device comprises an unmanned ship body; a propeller and a rudder blade are sequentially arranged at the bottom of the stern of the unmanned ship body from the bow to the stern; the propeller and the rudder blade are located on the middle longitudinal section of the unmanned ship body; the left side and the right side of the propeller are each provided with a composite fin stabilizer; the two composite fin stabilizers are symmetrically arranged left and right along the middle longitudinal section; the upper ends of the two composite fin stabilizers are fixed to the bottom of the unmanned ship body. The two composite fin stabilizers are installed on the two sides of a stern propeller and in front of a rudder according to the hydrodynamic characteristics of the single-propeller unmanned surveying vessel, and through the special design of main fins and auxiliary fins, the motion response of the unmanned surveying vessel in waves can be reduced, and the seaworthiness performance is improved; meanwhile, the two composite fin stabilizers can also play a role in protecting the propeller, so that the operation efficiency of the unmanned surveying vessel is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned ships, in particular to an anti-rolling device suitable for single-bladed unmanned survey ships. Background technique [0002] With the development of autonomous control technology, surface unmanned systems represented by unmanned ships are playing an increasingly important role in the construction of environmental fields such as marine environmental measurements. The operation of unmanned surveying ships does not have high requirements on the speed of the ship, but it needs to deal with unexpected sea conditions, so it often has high requirements on the seaworthiness and stability of the ship in wind and waves. [0003] At present, unmanned ships for offshore surveys are generally transformed from manned ships, which are small in size (length <10m) and have limited wind and wave resistance. Unmanned survey ships have weak wind and wave resistance when sailing in wind and waves, which reduces ...
