Embodiment 1

[0025] Embodiment one (comparative example):

[0026] see Figure 1-Figure 2 , the existing A-shaped bilge keel used for comparison mainly consists of two plates 2 and a round steel 3. From figure 2 It can be seen that the round steel 3 needs to be welded with the two plates 2 at the same time. The surface of the round steel is arc-shaped, and the positioning on both sides is difficult, and the positioning and operation during welding are relatively difficult.

Embodiment 2

[0028] see Figure 3-4 , an A-shaped bilge keel, comprising a flat bulb steel 4 and a plate 2; the straight end of the flat bulb steel 4 is fixedly connected to the hull 1; one end of the plate 5 is fixedly connected to the hull 1, and the other end is fixed to the hull 1. The convex end of the flat bulb steel 4 is welded and fixed; the cross section of the flat bulb steel 4 and the plate 2 forms an A-shaped angle.

[0029] see Figure 4 , two auxiliary connecting plates are welded and fixed on the hull 1, the flat end of the bulb flat steel 4 is welded and fixed to one of the auxiliary connecting plates, and the plate 2 is welded and fixed to the other auxiliary connecting plate.

[0030] see Figure 4 , the end of the protruding end of the bulb flat steel 4 is welded and fixed to the plate 2 .

[0031] see Figure 3-4 , the thickness of the raised end is greater than the thickness of the straight end.

[0032] see Figure 3-4 , the plate 2 is located below the bulb fla...

Abstract

The invention relates to an A-shaped bilge keel which comprises flat-bulb steel and a plate. The straight end of the flat-bulb steel is fixedly connected with a hull; one end of the plate is fixedly connected with the hull, and the other end of the plate is welded and fixed with the convex end of the flat-bulb steel; and an A-shaped included angle is formed between the flat-bulb steel and the cross section of the plate. The A-shaped bilge keel is composed of the flat-bulb steel and the plate, the structure of the A-shaped bilge keel is simplified, and the number of the components is reduced; the welding amount is reduced, and the difficulty of positioning and operation during welding is greatly reduced; and the whole structural design is simpler and clearer.

Description

technical field [0001] The invention relates to an A-shaped bilge keel, belonging to the technical field of ship bilge keels. Background technique [0002] The bilge keel is a necessary structural member for ship control roll. Among them, the A-shaped bilge keel is often used in high ice areas or ships with relatively high requirements for roll control. The conventional A-shaped bilge keel is as follows figure 1 and figure 2 As shown, it is mainly composed of two plates and a round steel. [0003] Among them, the round steel needs to be welded with two plates at the same time, and the positioning and operation during welding are difficult.
