Embodiment Construction

[0022] The present invention will be further described in detail with reference to the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, and are not used to limit the protection scope of the present invention.

[0023] Now in combination with the above-mentioned drawings, an implementation case of an arrangement of an internally stretched openable clam-type bilge keel on a ship is proposed.

[0024] The device is an internally stretched openable clamshell bilge keel, which is mainly used in various ships to suppress roll in various complex states.

[0025] Such as Figure 1 to Figure 5 As shown, a kind of internal expansion clamshell bilge keel of the present invention can be opened and closed. The main structure is composed of two parts: a fixed clamshell structure 2 and a rotating clamshell structure 1. The fixed clamshell structure 2 and the rotating clamshell structure 1 is a flat closed structu...

Abstract

The invention relates to a bilge keel. A body structure of the bilge keel comprises a fixed clamshell structure (2) and a rotary clamshell structure (1) which are in a flat shape after being combined; the head and tail ends are in a streamline shape; the fixed clamshell structure (2) is fixedly connected to a bilge strake (3); the rotary clamshell structure (1) is connected with the fixed clamshell structure (2) through a rotary shaft system; the rotary shaft system is used for opening and closing the rotary clamshell structure (1). The bilge keel can increase the rolling damping of a ship, effectively reduce rolling of the ship and enhance the rolling stability.

Description

technical field [0001] The invention relates to marine equipment for reducing rolling, in particular to a bilge keel used for anti-sinking, anti-rolling and anti-overturning of ships. Background technique [0002] The swaying motion of the ship is a harmful ship motion, which has adverse effects on the crew, hull structure, mechanical equipment, etc. Ship swaying motions include six types: roll, pitch, yaw, surge, sway and heave, among which roll has the greatest impact on ship performance, followed by pitch. In order to slow down or reduce the sway of the ship, an anti-rolling device can be added to the ship. [0003] According to the essential classification of the force constituting the stabilizing moment, the anti-rolling device can be divided into three types: gravity action type, fluid dynamic action type, and rotary force action type; according to the control form, it can be divided into passive type and active type. At present, the commonly used anti-rolling device...
