Telescopic fin stabilizer for unmanned ship, control system and control method

Abstract

The invention relates to a telescopic fin stabilizer for an unmanned ship, a control system and a control method, the fin stabilizer comprises a fin blade part, a first power mechanism, a first transmission mechanism, a fin shaft and a fin shaft limiter, and the fin blade part comprises a main fin unit, a second power unit, a second transmission mechanism and an auxiliary fin; the first power mechanism is connected with the fin shaft through the first transmission mechanism, the fin shaft is connected with the main fin unit and used for achieving unfolding and folding of the main fin unit, andmeanwhile the fin shaft limiter is installed on the first transmission mechanism and used for preventing the main fin unit from excessively stretching and locking the working state. The auxiliary finis mounted on the main fin unit, is connected with the second power unit through the second transmission mechanism, and is used for controlling the auxiliary fin to extend when the anti-rolling moment of the main fin unit is insufficient. Compared with the prior art, the telescopic fin stabilizer has the advantages that occupation of the internal space of the unmanned ship is reduced, enough anti-rolling torque can be provided under the condition that the navigational speed is not affected as much as possible, and the like.

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...

Problems solved by technology

However, at present, many stabilizer fins are integral structures. If the area of ​​the stabilizer fins is small, it is difficult to form a good anti-roll effect. The interior space of the human boat is very tight
