Description

[Detailed Description of the Invention] The present invention relates to a ship side water spray device that sprays water onto the ship side outer plating surface.

Conventionally, the ship's side near the shore connection in the center of LNG (liquefied natural gas) tankers has been constructed with round gunwales, which are used to protect the ship's side shell from fires while berthing and to prevent low-temperature damage caused by throughflow. Therefore, a device is installed to direct water from above the round gunwale onto the ship's outer plating.

In other words, the water jet ejected downward from the nozzle of the water supply pipe installed in the longitudinal direction above the round gunwale,
The water flows down the surface of the round gunwale and is guided to the ship's side shell, which protects the ship from fires and spills.

However, in such a conventional device, if a strong wind hits the water before the water flow completely reaches the side shell surface of the ship, the water flowing out may be blown away by the wind.

In addition, if the ship's side is formed with vertical gunwales, the upper edge of the ship's side skin will block the discharged water, causing the problem that water will accumulate on the deck along the ship's side, and overflow water will flow overboard. It will flow to.

The present invention aims to solve these problems, and is designed to provide a ship side water spray that can reliably guide the jet of water to the ship's side shell surface even under strong winds or in the case of vertical gunwales. The purpose is to provide equipment.

For this reason, the ship's side water spray device of the present invention has a water supply pipe with a nozzle hole installed above the deck along the ship's side, and one side edge welded to the outer surface of the pipe along the length of the water supply pipe. a guide plate, and the guide plate is arranged to protrude outward from the ship's side outer plate surface so as to cover the nozzle hole in order to guide the jet of water from the nozzle hole of the water supply pipe toward the outside of the ship. a first guiding part bent from the first guiding part in order to obliquely guide the ejected water flow guided along the first guiding part to the outer surface of the ship's side shell plating. It is characterized by having two guiding parts.

Hereinafter, a ship side water spray device as an embodiment of the present invention will be explained with reference to the drawings. FIG. 1 is a perspective view thereof, and FIG. 2 is a cross-sectional view thereof. A water supply pipe 3 with holes 2 is provided, and its base end is connected to a pump (not shown) via piping.

Further, along the longitudinal direction of the water supply pipe 3, a guide plate 4 is provided on the outer surface of the water supply pipe 3, one edge of which is welded.

The guide plate 4 includes a first guide part 4a that guides the water jet from the nozzle hole 2 of the water supply pipe 3 toward the outside of the ship, and a first guide part 4a that guides the jet water flow directed along the first guide part 4a to the side shell plate 5. The second guide portion 4b is configured to guide the guide obliquely toward the upper surface of the guide member.

The first guide part 4a is arranged to protrude outward from the ship's side shell plate 5 so as to cover the nozzle hole 2 from above, and the second guide part 4b
is arranged so as to be bent from the first guiding portion 4a, and its leading edge 4c is directed in a direction intersecting the outer surface of the ship's side shell plate 5 from diagonally above.

Note that the water supply pipe 3 is parallel to the first guide portion 4a of the guide plate 4.
A lower guide plate 4' is provided projecting from the lower guide plate 4', and both guide plates 4, 4' are connected via a spacer 6.

With the above-described configuration, when pressure water is sent to the water supply pipe 3, the water jetted from the nozzle hole 2 is directed to the guide plates 4, 4.
' and is first guided outboard along the first guide section 4a, then the direction is changed at the second guide section 4b and guided obliquely toward the outer surface of the side shell plating 5.

Therefore, even under strong winds, it will not be affected by the wind.
It becomes possible to reliably guide the jet water flow to the ship's side outer plating 5, and even in the case of a vertical gunwale as shown in the figure, problems such as water accumulation on the deck part do not occur.

The jetted water flow induced in this way causes the ship's side shell plate 5 to
Since the outer surface of the LN can be efficiently covered, this device can be used as a LN
If used in G tankers, etc., it will be possible to significantly improve their safety.

As described in detail above, according to the ship side water spray device of the present invention, the guide plate that guides the jet water flow from the nozzle hole of the water supply pipe above the ship side deck portion is configured to guide the jet water flow toward the outside of the ship. A first guiding part is arranged to protrude outward from the surface of the ship's side shell plate so as to cover the nozzle hole, and the jetting water flow guided along the first guiding part is directed to the side shell plate of the ship. It has an extremely simple structure consisting of a second guiding part that is bent from the first guiding part to guide the water diagonally toward the outside surface, and it is able to sufficiently supply the water jet to the outer surface of the ship. This makes it possible to carry out operations with high reliability, contributing to the prevention of disasters on LNG tankers, etc.
