Description

[0001] The present invention relates to a control apparatus for bilge keel,

The present invention relates to a bilge keel, and more particularly to a bilge killer.

In general, ships and offshore structures are subject to rolling due to the external characteristics of the ship and offshore structures, both in and out of service.

When such rolling fluctuations are caused by the weather conditions or waves, various problems arise. For example, if the resonance occurs due to the similarity of the wave period and the transverse wave period to the side of a ship or an offshore structure, the transverse fluctuation of the ship and the offshore structure can be greatly overturned. In the case of LNG carriers and oil tankers, when sloshing is carried out on the storage tank and the liquid cargo loaded by the rolling motion, fatigue cracks accumulate in the storage tank, and the storage tank may be destroyed.

For this reason, bilge kills have been proposed to reduce the transverse sway of ships and offshore structures. In addition, in order to more effectively reduce the rolling motion of vessels and offshore structure, Korean Patent Laid-Open No. 10-2010-0059142 proposes a foldable bilge kill of a ship whose length is adjusted, Korean Patent Laid- -0008331 proposed a rolling pin restraining device in which the projecting angle is adjusted, and Korean Patent Laid-Open Publication No. 10-2012-0081431 proposes a lift pin whose length and projecting angle are adjusted.

However, the folding bilge keel proposed in Korean Patent Laid-Open No. 10-2010-0059142 and the rolling prevention device proposed in Korean Patent Laid-Open Publication No. 10-2012-0008331 always protrude to the outside of the hull. Accordingly, when a ship having a folding bilge keel or a rocking restraining device of a ship or an offshore structure is navigated or stopped in the polar region, the folding bilge keel and the rocking restraining device of the ship may be damaged by ice.

The lift pin proposed in Korean Patent Laid-Open Publication No. 10-2012-0081431 can be embedded in the hull but has a multi-stage telescopic structure. As a result, the rigidity of the lift pin is low.

Korean Patent Laid-Open Publication No. 10-2010-0059142 (the name of the invention: folding bilge kill, public date: June 04, 2010) Korean Patent Laid-Open Publication No. 10-2012-0008331 (entitled "Rolling shake suppression device, public date: January 30, 2012) Korean Patent Laid-Open Publication No. 10-2012-0081431 (title of invention: a lift pin and a ship having the lift pin, published on July 19, 2012)

It is an object of the present invention to provide a bilge killer control device capable of being buried in a hull and having high rigidity and controlling the length and the angle of protrusion of the bilge killer. .

According to an aspect of the present invention, there is provided a bilge killer control device comprising: a bilge killer that is embedded in a bilge killer receptacle provided in a hull; A support table installed in the bilge keel; An upper link device that connects the upper portion of the support and the upper portion of the bilge keel; And a lower link device that connects the lower portion of the support and the lower portion of the bilge keel and is expandable and contractible.

The upper link unit includes an upper link hydraulic cylinder having one end rotatably coupled to the upper portion of the support, a lower link rotatably coupled to the upper portion of the bilge kill at one end, A lower link hydraulic cylinder having one end rotatably coupled to the lower portion of the support and a piston rotatably coupled to the lower portion of the bilge kill at one end and a lower link hydraulic cylinder having one end inserted into the lower link hydraulic cylinder, Lt; RTI ID = 0.0 > a < / RTI > lower link piston.

With the bilge kill control device according to the present invention as described above, the bilge killer can be embedded in the hull, has high rigidity, and the length and the angle of protrusion can be adjusted.

1 is a side view showing a bilge killer control apparatus according to an embodiment of the present invention.
2 is a cross-sectional view illustrating a bilge killer control apparatus according to an embodiment of the present invention.
FIGS. 3 to 5 are views for explaining the operation and effect of the bilge killer control apparatus according to an embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. This does not mean that the technical ideas and categories of the present invention are limited.

Hereinafter, a bilge kill control device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a side view of a bilge killer control apparatus according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view illustrating a bilge killer control apparatus according to an embodiment of the present invention.

1 and 2, a bilge killer control apparatus 100 according to an embodiment of the present invention includes a bilge killer 120 which can be embedded in a bilge killer receiving unit 110 provided in the hull 101, A supporting bar 130 installed on the bilge keeper accommodating part 120 and a lower part of the upper link device 140 and the supporting bar 130 that connect the upper part of the supporting bar 130 and the upper part of the bilge kill 120, And a lower link device 150 connecting the lower portion of the keel 120 and extending and retracting.

The bilge keel 120 may be integrally formed without a connecting structure and a stretching and contracting structure. As a result, the rigidity of the bilge keel 120 is increased.

The cross section of the bilge keel 120 may be approximately semicircular. Accordingly, when the bilge keel 120 is received in the bilge keel receiving portion 110, one side of the bilge keel 120 forms a side surface of the ship.

The upper link device 140 includes an upper link hydraulic cylinder 141 whose one end is rotatably coupled to the upper portion of the support 130, one end rotatably coupled to the upper portion of the bilge killer 120, And an upper link piston 142 that is inserted into the cylinder 141. The lower link device 150 includes a lower link hydraulic cylinder 151 whose one end is rotatably coupled to the lower portion of the support 130, one end rotatably coupled to the lower portion of the bilge killer 120, And a lower link piston 152 inserted into the hydraulic cylinder 151. The hydraulic pressure of the upper link hydraulic cylinder 141 of the upper link device 140 and the hydraulic pressure of the lower link hydraulic cylinder 152 of the lower link device 150 are adjusted so that the protrusion length L of the bilge killer 120 and the protrusion angle (A) is adjusted.

Hereinafter, the operation and effect of the bilge killer control apparatus according to one embodiment of the present invention will be described with reference to the drawings.

FIGS. 3 to 5 are views for explaining operations and effects of a bilge killer control apparatus according to an embodiment of the present invention.

Thus, the bilge killer 120 is prevented from being damaged by ice.

4 and 5, when a ship or an offshore structure equipped with the bilge killer control apparatus 100 according to an embodiment of the present invention is stopped in a sea where the waves are intense or the ocean is severely damaged, The hydraulic pressure of the upper link hydraulic cylinder 141 of the lower link device 140 and the hydraulic pressure of the lower link hydraulic cylinder 152 of the lower link device 150 are adjusted so that the protrusion length L and the protrusion angle A of the bilge killer 120 are . As a result, the rolling motion of ships and offshore structures is more effectively reduced.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Therefore, the true scope of technical protection of this invention should be determined by the technical idea of the appended utility model registration claim.
