Problems solved by technology

However, the bilge keel is a passive anti-rolling device, and for some ocean-going high-speed ships, its effect is far from meeting the requirements
Therefore, its engineering application is limited

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0036] Such as figure 1 As shown, a ship stabilizer fin with a semi-active control type inerter structure includes an upper shell 2, a lower shell 19, a ball screw type inerter assembly, a rack and pinion transmission mechanism and a sealing device. The lower shell 19 is fixedly installed on the hull plate 17, the upper shell 2 is fixedly connected with the lower shell 19, and the ball screw type inerter assembly, the rack and pinion transmission mechanism and the sealing device are arranged on the In the inner cavity between the upper housing 2 and the lower housing 19; the middle position of the lower housing 19 is provided with a penetrating inerter installation hole, and the ball screw type is fixedly installed in the inerter installation hole. The inerter assembly, ...

Abstract

The invention discloses a ship fin stabilizer with a semi-active control type inertial structure. The ship fin stabilizer comprises an upper shell, a lower shell, a fin rod, a ball screw type inerter assembly, a gear and rack transmission mechanism and a sealing structure. The upper shell and the lower shell are connected. The lower shell and a hull board are connected. The ball screw type inerter assembly comprises a penetrating screw, a bearing lower limiting ring, a flywheel, a bearing upper limiting ring and a ball. The sealing structure comprises a rubber ring A, a sealing shell, a rubber ring B and a welding sleeve. By the adoption of the ship fin stabilizer, the ball screw type inerter assembly is designed into an inner control structure of the semi-active fin stabilizer; compared with an active fin stabilizer structure, the structure is greatly simplified; compared with a bilge keel, the ship fin stabilizer has the beneficial effects of being optimized in stabilization effect, economical, environment-friendly, capable of saving energy and high in engineering application value.

Description

technical field [0001] The invention relates to a ship fin stabilizer structure, in particular to a ship fin stabilizer with a semi-active control inertial structure, belonging to the technical field of ship equipment. Background technique [0002] When a ship encounters wind and waves during navigation, it will sway laterally. The lateral sway of the ship will reduce the seaworthiness of the ship, damage the hull structure, affect the normal operation of equipment and instruments, and cause cargo displacement or impact damage , It will also make the staff or passengers dizzy, and will greatly affect the combat effectiveness of combat ships. In order to reduce the lateral swing of the ship, the current solution with better effect is to install fin stabilizers on the bilge of the ship. [0003] The stabilizer fins are installed in the bilge of the two sides of the ship, and the section is wing-shaped, also known as the side rudder. The stabilizer fins are rotated by the opera...
