Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like image 3 As shown, a set of anti-rolling devices adopted in the present invention includes an outer shaft 3 on which an arc-shaped anti-rolling plate 1 and a rectangular anti-rolling plate 2 are connected. One end of the telescopic control rod 4 is connected to the outer shaft 3 , and the other end is connected to the hydraulic power unit 5 , and the hydraulic power unit 5 is connected to the control system 6 . The control system 6 controls the operation of the hydraulic power unit 5 according to the instruction signal, drives and controls the expansion and contraction of the telescopic control rod 4, thereby controlling the position of the anti-rolling plate relative to the hull.

[0026] like image 3 As shown, the arc-shaped anti-rolling plate 1 is designed according to the shape of the bilge of the hull to ensure that it fits the bil...

Abstract

The invention provides a telescopic stabilizer. Each group of stabilizers comprises an external shaft, stabilizing plates, a control rod, a power unit and a control system and is characterized in thattwo stabilizing plates are arranged and are a first stabilizing plate and a second stabilizing plate which are connected with each other through the external shaft; the external shaft is connected with a power device through the telescopic control rod; the control system is connected with the power unit; the power unit is connected with the telescopic control rod; three groups of stabilizers aremounted within a range of 1 / 3-1 / 4 of ship length in the middle of a hull; the stabilizing plates of the stabilizer in the middle group are wider; and the stabilizing plates of the stabilizers in the other two groups are narrower. According to the telescopic stabilizer, stabilizing effects at various navigational speeds can be guaranteed, and meanwhile, various sea conditions can also be considered; and therefore, the stabilizing effect under a severe sea condition can be guaranteed, and lower resistance under a more peaceful sea condition can also be kept.

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...
