Abstract

PURPOSE:To facilitate mount/dismount of working vessel by arranging square lower hull through guide post onto upper hull having U-shaped top view then regulating ballast in each hull. CONSTITUTION:A portion of hull of submergible barge to be used for transporting various working vessels is splitted into upper and lower sections. The upper hull 1 has U-shaped top view and provided with ballast tanks 6, 7. The lower hull 2 is made square and provided with ballast tank 8 while a guide post 4 provided with a stopper 9 is planted and penetrated through a guide hole 5 of upper hull 1 to constitute both hulls 1, 2. When transporting a working vessel 13, ballast in both hulls 1, 2 is regulated to mount easily onto a barge.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a submersible bullge capable of submersible water.

With conventional submerged pull barges, the hull (barge) must be submerged on a flat bottom at an appropriate depth in order to load or unload objects for continuous shooting.
When loading or unloading, there were problems such as having to select a specific area and also paying considerable attention to sea conditions such as tides and wave size.

The present invention was made in order to improve the above-mentioned problem, and the hull is divided into an upper hull and a lower hull, the upper hull has a planar shape that is approximately U-shaped, and the lower hull has a planar shape that is approximately U-shaped. The upper and lower hulls are connected via guide struts so that they can move up and down, and each is equipped with water supply and drainage equipment for ballast to form a submerged pull barge, making it possible to load or unload cargo. The purpose of the present invention is to provide a submerged pull barge that can easily and easily load or unload cargo at any location without having to select a specific area.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the present invention, as shown in FIG.
＞ is divided into an upper hull (upper hull) and a lower hull (lower hull). That is, 3 is a notch, 1a is a wide part that the notch 3 cannot reach, and lb
are both side edges narrowed by the notch 3.

In addition, the lower hull 2 has a substantially square planar shape,
Two guide struts 4 are provided on each side edge of the lower hull 2 to project upward, and holes 5 that are slidably fitted with these four guide struts 4 are provided in each of the upper hull l. The upper hull 1 and the lower hull 2 are connected to each other via these guide struts 4 so as to be vertically movable, and each of the upper hull 1 and the lower hull 2 is provided with water supply and drainage equipment for ballast. establish. In other words, 6 and 7 in Fig. 2 are the ballast tanks installed in the upper hull 1, and 8 is the ballast tank installed in the lower hull 2.
This is the internal ballast tank.

In addition, 9 in the figure is a stopper fixed to the upper end of the guide column 4 to prevent it from being pulled out, 10 in FIG. , a notch provided to avoid interference with the upper hull 1.

Next, the operation of the apparatus of the present invention constructed as described above will be explained.

FIG. 2(a) is a sectional view showing a state in which the submerged pull purge of the present invention is floating on the water surface with no load, and in this case, the ballast tank 8 in the lower hull 2 is filled with air. . Therefore, the lower hull 2 floats to the uppermost position and overlaps with the upper hull. In this case, in order to balance the entire purge, a small amount of water 12 is poured into the ballast tank 7 of the upper hull 1. This state is suitable for navigation when the ship is empty.

Next, for example, in order to load the work boat 18 shown in FIG. 2, as shown in FIG. Inject water into the tank 6.7 and sink the lower hull 2 while keeping the second hull 1 horizontal.In this way, the lower hull 2 will be connected to the four guide columns 4, The lower hull 2 sinks directly below the upper hull 1 while being guided by the holes 5 in the upper hull.Even if the lower hull 2 reaches its lowest limit, the stopper 11 prevents the support 4 from coming out of the hole 5. do not have.

Once the lower hull 2 has sunk, the work vessel 13 to be loaded is introduced into the notch 3 of the upper hull 1 as shown in FIG. is discharged to the outside. As the discharge of this ballast water 14 progresses, the lower hull 2 gradually rises to the surface and eventually reaches the second
As shown in FIG.

When unloading, the loading operation described above may be reversed. That is, from the state shown in FIG. 2 ((1)), water is first injected into the lower hull 2 to sink the lower hull 2 as shown in FIG. Just pull it out.

Since the purge of the present invention is as described above, there is no need to select a specific area when loading or unloading goods as in the past, and it is possible to simply and easily transport goods at any location. The excellent effect of loading and unloading can be obtained.
