Retractable emergency brake fin stabilizer for ship

Abstract

The invention provides a retractable emergency brake fin stabilizer for a ship. The fin stabilizer comprises a fin stabilizer body (1), an auxiliary fin (3), a hydraulic cylinder (4), a hydraulic motor (5), an oil pipeline (6) and a hydraulic oil pump (7). The fin stabilizer is characterized in that the fin stabilizer body (1) is of an inner cavity structure, a notch is formed in the bottom of the cavity, the notch is matched with the auxiliary fin (3), the two sides of the auxiliary fin (3) are provided with guide rails which are connected with the two sides of the fin stabilizer body (1) in a sliding mode, the hydraulic cylinder (4) is fixed to the inner wall of the cavity of the fin stabilizer body (1), the hydraulic oil pump (7) is communicated with the hydraulic cylinder (4) through the oil pipeline, power for reciprocating movement of the auxiliary fin (3) is provided, the hydraulic motor (5) is fixed to one side of the fin stabilizer body (1) and is communicated with the hydraulic oil pump (7) through the oil pipeline (6), the hydraulic oil pump (7) drives the hydraulic motor (5) to rotate and output torque, power allowing the fin stabilizer body (1) to swing in the vertical plane where the center axis is located is provided, and the fin stabilizer body is further used, so that an emergency brake function is added on the basis that the original stabilizing function of the fin stabilizer is not affected, the fin stabilizer is used to the largest extent, and the aim of braking the ship in emergencies through the fin stabilizer is achieved.

Description

technical field [0001] The invention relates to the technical field of marine braking devices, in particular to a marine retractable emergency braking stabilizer fin. Background technique [0002] At present, there are two types of fin stabilizers: retractable and non-retractable. It mainly uses the fin body to rotate according to the law of wave disturbance under the control of the fin stabilizer control system. When the lift generated by one fin is upward, the other side generates a downward lift, which generates a stabilizing moment relative to the roll axis, and finally overcomes the roll. All in all, fin stabilizers are mainly used to overcome various shocks caused by waves, sea wind and other factors when the ship is sailing at sea, especially the impact caused by roll, but fin stabilizers are still only used in emergency situations. Anti-rolling effect, single purpose of work, no braking effect. Contents of the invention [0003] In view of this, the present inven...
