Problems solved by technology

At present, when the bilge keel in the prior art is installed, due to the longer hull structure and more welding work for the continuous structure, it will cause large welding stress on the outer plate of the ship. , the complete bilge keel cannot be pre-installed in the small closing stage, and a partial bilge keel of about 1m must be reserved at the large segmental joint. Participating in the overall longitudinal bending, when the bilge keel partially falls off, it will cause the entire bilge keel to fall off and hit the hull, resulting in the expansion of the scope of damage

Abstract

The invention discloses a bilge keel structure of a ship, and relates to the technical field of ship design. The bilge keel structure of the ship is symmetrically arranged on bilge parts on the two sides of the ship in the width direction and connected with an outer plate of the ship, the bilge keel structure comprises a plurality of bilge keel bodies and a plurality of cushion blocks, the multiple bilge keel bodies are evenly arranged at intervals in the hull streamline direction of the ship, and all the bilge keel bodies extend in the hull streamline direction of the ship. The multiple bilge keel bodies are all connected with the outer plate. The multiple cushion blocks are evenly arranged at intervals in the streamline direction of a ship body, the multiple cushion blocks correspond to the multiple bilge keel bodies one to one, the cushion blocks are arranged between the bilge keel bodies and the outer plate, and the two sides of the cushion blocks are connected with the bilge keel bodies and the outer plate correspondingly. The multiple bilge keel bodies are evenly arranged in the streamline direction of the ship body at intervals, the workload of continuous welding can be reduced, and the mounting and assembling preassembling rate is increased. Meanwhile, when one bilge keel body falls off, other bilge keel bodies cannot be influenced, and therefore the damage influence range cannot be enlarged.

Description

technical field [0001] The invention relates to the technical field of ship design, in particular to a bilge keel structure of a ship. Background technique [0002] The rolling of the ship has the greatest impact on the performance of the ship. In order to slow down or reduce the rolling of the ship, an anti-rolling device can be added to the ship. At present, the commonly used anti-rolling devices for ships include: bilge keels, fin stabilizers, water tanks, gyroscope anti-roll devices and rudder anti-roll devices, etc. Among them, the bilge keel is widely used because of its simple structure, low cost, convenient maintenance and good performance. Almost every ship is equipped with a bilge keel. The principle of bilge keel anti-rolling is to use it installed on the shell of the bilge of the hull to generate additional water resistance to the ship's roll, so as to reduce the ship's roll. Generally speaking, the bilge keel is a long strip fixedly installed on the bilge outs...
