Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to a novel water curtain guide device for an LNG loading and unloading station. Background Art

[0002] On LNG transport and bunkering ships, when transferring liquid cargo at the loading and unloading station, the temperature of LNG in the liquefied state is as low as -162°, which is very easy to cause low-temperature damage to the ship's deck and outer plate. In order to avoid or reduce such damage, water curtains are generally installed on the outer plate of the hull to protect the outer plate.

[0003] However, how to form a uniform water curtain on the outer plate of the water curtain tube becomes a difficult problem. Utility Model Content

[0004] In response to the above problems, the utility model provides a water curtain guide plate, which can form a uniformly distributed water curtain, thereby protecting the outer plate. The specific solution is as follows:

[0005] A novel water curtain diversion device for an LNG loading and unloading station includes a support frame and a diversion plate. The support frame is installed on the deck at a position behind the ship's side. The diversion plate is installed on the side of the support frame facing the ship's side. The diversion plate includes a vertically arranged water baffle, a cover plate arranged on the top of the water baffle, and a diversion plate arranged at the bottom of the water baffle. The cover plate is arranged toward the ship's side. The diversion plate and the cover plate are on the same side, and the bottom of the diversion plate overlaps the ship's side.

[0006] It also includes a water curtain pipe, which is arranged along the length direction of the guide plate, and the guide plate half surrounds the water curtain pipe, and the water outlet of the water curtain pipe is arranged facing the guide plate.

[0007] Furthermore, a plurality of notches are arranged in sequence along the length direction of the guide plate, and a pipe bracket is provided in the notch. The pipe bracket is an inverted L-shaped angle plate, comprising a support plate fixedly connected to the deck and a horizontal frame plate located on the top of the support plate. A pipe clamp for fixing the water curtain pipe is installed at the bottom of the horizontal frame plate.

[0008] Furthermore, the water curtain pipe is composed of a plurality of branch pipes connected in series, the length of the branch pipe corresponds to the interval between two adjacent notches, and the two adjacent branch pipes are butt-jointed via flanges.

[0009] Furthermore, there are multiple support frames, which are located on both sides of each gap. The water retaining plate is located on the side of the gap and is provided with a connecting plate that fits with the side of the support frame. The connecting plate is fixed to the support frame by bolts.

[0010] Furthermore, the support frame is angle steel.

[0011] Furthermore, the cover plate is perpendicular to the water retaining plate, and a downwardly bent edge is provided on the outer side of the cover plate.

[0012] Furthermore, the cover plate, water baffle plate and drainage plate are integrally formed stainless steel plates.

[0013] Compared with the prior art, the advantages of the present invention are as follows:

[0014] 1. The utility model forms a semi-enclosed guide plate for the water curtain pipe, so that the water flow ejected from the water curtain pipe is evenly distributed on the plate, and then the water is drained by the guide plate to form a uniform and continuous water curtain, thereby achieving the effect of effectively protecting the outer plate of the ship;

[0015] 2. The water curtain guide plate has the characteristics of simple production and lighter weight than conventional forms;

[0016] 3. When installing the pipe support, directly dig a groove at the corresponding location, which is smaller in size and has the advantage of being convenient for layout in areas with a large number of branch pipes. BRIEF DESCRIPTION OF THE DRAWINGS
