Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster prevention facility for a container ship in which containers are loaded so as to cross a deck.

Here, disaster prevention means windproof, rainproof, waveproof, snowproof and the like.

[0003]

2. Description of the Related Art This type of disaster prevention equipment is used for container ships in which containers are loaded on decks, and in some cases, also on hatch covers. This type of disaster prevention equipment is installed on a container ship that does not have a hatch cover and has an open cargo compartment. In this kind of container ship, at least two containers, especially 4
To accommodate less than one container above the deck, the container loading device extends upward from the double bottom, past the narrow deck, past the side of the cargo compartment.

Such a ship is, for example, German Patent Publication No. 4
No. 022504. This known ship has a narrow main deck beside the cargo compartment. Also,
An outer sidewall extending upward is provided to protect the container. Further, it is described that the superstructure of a ship can be closed by a light-weight automatically operated hatch cover or a cover such as a hatch cover. However, the details of this cover are not described.

WO 87/00137 discloses an open container ship. However, the sides of the double wall extend to the area of the uppermost container and no top cover is provided.

German Utility Model Registration No. 7520130 describes a container ship in which the container guide part extends beyond the height of the disaster prevention deck. However, there is no cover on the container surface only on the side disaster prevention wall.
Judging from the layout of the breakwater, this type of cover is not expected.

Normally, in the case of an open container ship, rainwater entering from above can be removed by a bilge pump. However, bilge pumps are not satisfactory in the case of heavy rainfall, for example in the tropics. further,
It has been found that when a container ship is not full of containers, the uneven loading of the containers results in uneven surfaces and increased wind resistance.

SUMMARY OF THE INVENTION It is an object of the present invention to bring out the advantages of a container ship even in harsh weather conditions and / or loading conditions and to remove it easily so as not to interfere with the loading and unloading of containers. It is to provide disaster prevention equipment for possible container ships.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention extends beyond the uppermost container, extends over the width of the cargo compartment, and has an interval corresponding to the length of one container. And a cover surface consisting of a corrugated plate is provided, the end of the cover surface extending transversely to the corrugations being provided. , Each of which is easily removably mounted and can be fixed on the strips of two adjacent frames.

The cover is reinforced at its ends laterally with respect to the corrugations by a transverse frame which is mounted or inserted. The lateral frame can be configured in the shape of a prism or a T, and its horizontal legs can rest on a horizontal surface (rest) on the side wall of the lateral conduit. Between these two horizontal planes, a releasable connection can be achieved using a pivotable lever or similar means for a form-constrained or force-restrained connection.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

According to FIG. 1, a container ship has a double bottom 1
And a double-walled side wall 2 capable of accommodating the tank chamber, and a narrow deck 3 provided on the side wall 2 on both sides of the loading chamber. Depending on the height of the deck 3 or the freeboard, a side protection wall 9 for the container 4 can be provided on the deck 3.

This type of ship is provided with a mounting frame. The mounting frame is composed of a horizontal upper strip portion 6 and a vertical frame support portion 5. The frame column 5 can extend along the inner side wall to the double bottom 1. On the other hand, for example, in relation to the partition wall 8, the frame strut portion 5 may be configured as an upward extension portion of the partition wall 8 with a space from the inner side wall. The upper strip 6 is configured as a lateral conduit and therefore covers 1
It can also be used as a rain gutter capable of flowing water flowing from 0. Water flowing through the gutter flows out from the side edge to the outside of the freeboard. An upper end of a vertical carrier 7 that carries a container guide rail (not shown) is also fixed to the upper strip 6.

As can be seen from FIGS. 1 and 2, in the illustrated embodiment four or more containers are provided above the deck 3 and above the side protection wall 9 barely three containers 4 are provided.
Is provided. In FIG. 2, the upper edge of the side protection wall 9 is indicated by the line 9a, and the height of the deck 3 is indicated by the line 3a. The cover 10 forms a protective roof above the container 4. The container is not protected at the side protection wall 9 or at the upper side of the corresponding edging.

The distance between the frames 5 and 6 substantially corresponds to the length of the container 4 loaded between them. The cover surface 10 between the two frames consists of a wide central part 11 and two narrow side parts 12. The waves on the cover surface 10 travel in the longitudinal direction of the container ship. Reinforcing horizontal frames 13 are arranged at both ends of the cover surface 10 extending in the horizontal direction with respect to the waves. The horizontal frame 13 can be installed so as to be rounded in front of the end of the wavefront, in which case drain holes are provided in the horizontal frame 13 for each wave trough (FIG. 3). Alternatively, the transverse frame 13 with teeth can be welded below the corrugations of both parts 11 and 12 of the cover surface 10, in which case the edges of the cover surface 10 are
It projects through 3 into the lateral conduit 6 (FIGS. 2 and 4). The horizontal frame 13 is bent downward to form a T-shape,
It is mounted on the upper lateral strip 6a on the side wall 6b of the lateral conduit 6. In order to prevent the covers 11, 12 from coming off, an easily removable connection must be achieved by means of a pivotable lever or similar means. In this case, the deformation of the mounting frame from the hull is considered.

FIG. 4 shows the operating screw 15 rotatably arranged on the side wall 6b. The operation screw 15 can be screwed into a slit of a fixed portion attached to the horizontal plate 13,
Fixed by nuts. A bell crank, for example, can be used as another suitable fixing means for fixing the lateral plate 13 to the strip 6a.

The central portion 11 and side portions 1 of the cover surface 10
2 is provided with a metal fitting 14. The fitting 14 is gripped by the container lift and can be removed laterally, for example on another cover surface.

Also attached to the upper strip 6 having the lateral conduit is the upper end of a vertical carrier 7 (FIG. 3) for a container guide rail, not shown.

Advantageously, the waves on the cover surface 10 are angular, having a height of 300 mm and a width of the narrow surface of the waves of about 300.
mm, the width of the wide surface is advantageously about 600 mm. The material of the cover surface 10 is steel for construction or steel for hulls, and is provided with a corrosion-resistant coating portion.

From a model experiment of such a container ship according to the invention, it has been found that a disaster-proof roof significantly reduces wind resistance, especially when the container cargo has not reached its maximum height.
