Abstract

The invention provides a T-shaped rotor foil low-speed stabilization apparatus. The T-shaped rotor foil low-speed stabilization apparatus comprises a column and horizontal rotor cylinders, the upper end of the column is fixed at the bottom of a ship, the lower end of the column is connected with the horizontal rotor cylinders, hydraulic cylinders are positioned at the inner part of the column, the hydraulic cylinders drive the horizontal rotor cylinders to swing back and forth, and motors at the inner parts of the horizontal rotor cylinders drive the horizontal rotor cylinders to rotate. At the zero speed, a T-shaped rotor foil is driven by the hydraulic cylinders, the horizontal rotor cylinders swing to a position vertical to the water-flow direction and swing back and forth regarding the position as the initial position, and the motors at the inner parts of the horizontal rotor cylinders drive the horizontal rotor cylinders to rotate; at the low speed, the horizontal rotor cylinders swing to the position vertical to the water-flow direction, and the motors at the inner parts of the horizontal rotor cylinders drive the horizontal rotor cylinders to rotate. According to the stabilization apparatus, the ship sea-keeping can be improved, when the T-shaped rotor foil does not need to operate, the horizontal rotor cylinders are taken back to the tail part of the column driven by the hydraulic cylinders, the navigation resistance can be reduced, fuels are saved, and the speed is increased.

Description

technical field [0001] The invention relates to an anti-rolling device, in particular to a low-speed anti-rolling device for a T-shaped rotor blade. Background technique [0002] With the rapid development of the maritime transport industry, all kinds of ships have increased. Catamaran is one of the most widely used ship types. Catamarans are generally favored for their large deck area, large cabin space, and convenience for luxurious decoration. They have become a type of ship that has developed rapidly, is widely used, and has a large number of constructions in recent years. Since the width of the catamaran is much larger than that of the monohull, its stability is obviously better than that of the monohull, and it has the ability to withstand relatively large wind and waves. The catamaran not only has good maneuverability, but also has a resistance peak that is not obvious. , Large loading capacity and other characteristics, so it is widely used as military ships and ci...
