Telescopic anti-rolling plant

Abstract

The invention provides a telescopic anti-rolling plant which comprises three anti-rolling devices of the same structure and in different sizes. Each anti-rolling device comprises an outer shaft, anti-rolling boards, a joystick, a power unit and a control system, and the two anti-rolling boards are the first anti-rolling board and the second anti-rolling board which are connected through the corresponding outer shaft. Each outer shaft is connected with the corresponding power unit through the corresponding telescopic joystick. Each control system controls the corresponding power unit to work and drives and controls the corresponding telescopic joystick to stretch and retract so as to control the positions of the corresponding anti-rolling boards relative to a hull. The three anti-rolling devices are installed in the position from 1 / 3 to 1 / 4 of the middle portion of the hull, the anti-rolling boards of the middle anti-rolling device are wide, and the anti-rolling boards of the other twoanti-rolling devices are narrow. The anti-rolling effect at various navigation speeds can be guaranteed, meanwhile, various sea conditions can be considered, the anti-rolling effect in the severe seacondition is guaranteed, and the low drag can be kept in the calm sea condition as well.

Description

technical field [0001] The invention relates to a new type of telescopic anti-rolling equipment. Background technique [0002] When a ship sails in waves, various swaying motions will be produced due to the interference of wind and waves and other factors, among which rolling motion is the most harmful to the ship. Large-scale rolling motion of the hull will not only affect the comfort and life safety of the crew, but also reduce the speed of the ship, deteriorate the working condition of the main engine, and reduce the stability. In severe cases, it may cause capsizing accidents. Therefore, how to effectively reduce rolling is a key issue in ship design. [0003] Rolling damping has a great influence on the rolling of ships. In order to increase the rolling damping of ships, the existing single anti-rolling equipment can no longer fully meet the anti-rolling needs of all ships. Traditional fin stabilizers cannot work effectively at zero speed and low speed, such as moorin...
