Abstract

The invention relates to a retractable fin stabilizer for an unmanned boat, a control system and a control method. The fin stabilizer includes a fin blade part, a first power mechanism, a first transmission mechanism, a fin shaft and a fin shaft limiter , the fin blade part includes the main fin unit, the second power unit, the second transmission mechanism and the auxiliary fin; the first power mechanism is connected to the fin shaft through the first transmission mechanism, and the fin shaft is connected to the main fin unit to realize the main fin unit Expand and retract, while the fin axis limiter is installed on the first transmission mechanism to prevent the main fin unit from over-extending and lock the working state; the auxiliary fin is installed on the main fin unit, and through the second transmission mechanism and the second The power unit is connected to control the extension of the auxiliary fin when the anti-rolling moment of the main fin unit is insufficient. Compared with the prior art, the present invention not only reduces the occupation of the inner space of the unmanned boat, but also can provide sufficient anti-rolling moment without affecting the speed of the ship as much as possible.

Description

technical field [0001] The invention relates to the technical field of unmanned boats, in particular to a retractable fin stabilizer for unmanned boats, a control system and a control method. Background technique [0002] With the deepening of human development and utilization of marine resources, unmanned surface vehicles, as a surface platform capable of autonomous navigation and performing various complex tasks, are also facing an increasingly complex marine environment. However, due to the generally small displacement of unmanned boats, when navigating in complex sea conditions, strong rolling will occur, which will reduce the maneuverability of unmanned boats, not only increase energy consumption, but also may cause the accuracy of shipboard equipment to decrease or even malfunction. Harm navigation safety and work efficiency. [0003] In the ship anti-rolling equipment, the fin stabilizer is the most effective device at present. The angle of the fin stabilizer is adju...
