Description

[Detailed Description of the Invention] The present invention divides the hull of the hopper into two in the length direction and opens the hull in the lateral direction, so that the earth and sand from the hopper can be passed through the space between the left and right hulls of the two halves. This relates to a two-part continuous soil supply system that can be dropped.

Conventionally, the continuous supply of earth and sand, in which earth and sand and rocks are loaded in two halves and then opened and dumped into the water, has been devised and put into practical use; Among continuous feeders, when a two-part hull is opened using two hinges, the hull rotates around the hinges to dump earth and rocks, so when the hull is opened, the hull rotates around the hinges.
In shallow waters, there is a limitation in that the hull comes into contact with the bottom when opened.

On the other hand, since the hulls are connected by hinges, there is an unavoidable problem that as the hull becomes larger, the strength of the hull becomes weaker and the distortion increases.

Therefore, the present invention was made in order to solve the above-mentioned conventional problems, and the hull is formed into two parts in the length direction, and the hull is opened laterally to dump rocks and earth. The purpose is to provide a continuous supply of earth and sand that can maintain sufficient hull strength and dump earth and sand even into shallow l17+ water.

That is, the two-split continuous earth and sand feeding system of the present invention forms a hull having a hopper into two parts in the length direction, and
At both the front and rear ends of the two-part part, there is a joint part that can horizontally slide horizontally in the lateral direction of the hull and the tightening and opening b'1 of the male and female mating parts. ``This is illustrated by providing a locking device capable of ``J''.

Below, referring to one drawing, the two-split type continuous soil feeding in the embodiment of the present invention will be explained.As shown in Fig. 1,
A ship body having a hopper 1 and having a trapezoidal cross section is formed into two halves in the length direction, with a right half shown by two people and a left half shown by 2B, and the right half 2A And at both front and rear ends of the left half 2B, there is a phase l in the lateral direction indicated by W of the hull.

The left half 2B changes from the fastened state shown by the solid line to the released state as shown in the center of the hopper 1 in FIG. The fitting direction of the joints 6 and 4 is indicated by W on the hull (move in the yellow direction and move the hopper 1 as shown in Figure 6).
An opening 11 will be formed in the bottom of the ship, and earth and sand 16 will be discharged into the water through the opening 11 and dumped.

On the other hand, when the earth and sand 16 is squeezed and twisted, no pressure is generated by the earth and sand 16, so the release/linda 1u provided with the female and male fitting parts 5, 4V'LC shown in FIG. 2 is operated. The openings 11 in the right half 2A and left half 2B of the hull can be opened.

In addition, in FIG. 2, two sets of locking devices 5 are shown in a high position.

A triangular protrusion 12 and a gasket 16 can be provided at the contact portion of the opening 11 with the portion 2B, respectively.

Therefore, in the continuous earth and sand feeding system of the present invention, the hull is formed into two halves in the length direction, and the female fitting parts provided at both ends can be slid horizontally in the lateral direction of the hull. ,
There is an advantage that the size of the hull can be increased by i(+).

-Ma/ko, since the hull split in two opens laterally,-
1.Even if the water depth at the place where the sand is to be dumped is as shallow as the 6.74 bearing draft of the ship, it is possible to dump the sand.

Historically, it has been possible to install as many locking devices as necessary to tighten and release the male and female mating parts of the two-part hull, making it possible to reduce the gap between the openings in the left and right hulls due to the hull shape. Moreover, since contact between the gaps can be maintained through the packing and the triangular protrusion, it is easy to prevent water leakage.

A multi-segmented earth transport ship, characterized in that a male and female fitting part that can be mutually slid horizontally in the lateral direction of the hull and a locking device that can tighten and open the male and female fitting parts are provided at both ends. 3. Detailed Description of the Invention The present invention relates to a multi-segmented cargo ship which is divided into multiple sections and opened laterally so that earth and sand from the hopper can be dropped through the space between the left and right hulls. Conventionally, various methods of continuous soil feeding have been devised and put into practical use, in which earth and sand or rocks are loaded into a ship that is split into two, and the hull of the two parts is opened and dumped into the water. Among shipping vessels, when the two-part hull is opened using two hinges, the hull rotates instead of the hinges to dump sand and rocks. At sea, there is a limit that the hull can only come into contact with the seabed once when opened. On the other hand, since the hulls are connected by hinges, there is a problem in that as the hull becomes larger, the strength of the hull becomes weaker and the distortion increases, making it unavoidable. Therefore, the present invention has been made in order to solve the above-mentioned problems of the conventional art.The present invention is made by forming the hull into at least two halves in the length direction, and opening the hull laterally to dump rocks and earth. The purpose of the present invention is to provide an earth transport vessel that can maintain sufficient hull strength and dump earth and sand even into shallow irrigation water. That is, the multi-segmented earth transport vessel of the present invention has a hull having a hot slit formed into at least two halves in the length direction, and both front and rear ends of the at least two halves, 4jl4 of the hull. It is constructed by providing a male and female fitting part that can be slid horizontally relative to each other in the direction, and a locking device that can tighten and open the male and female fitting part. The multi-segmented earth carrier according to the embodiment of the present invention will be explained below with reference to the drawings.

This locking device 5 includes a tension bar 6, a toggle device 7, a hydraulic cylinder 8, a hydraulic cylinder salt (= number of J eye plates 9 The locking device 5 having the following configuration is provided at the rear circular end of the hull. As shown in the front sectional view of FIG. 5, the toggle device 7 is bent to the state shown by the broken line in FIG. 2 by operating the hydraulic cylinder 8. The half 2A and the left half 2B go from the fastened state shown by the solid line to the released state as shown in the center of the hopper 1 in FIG. 6, and due to the pressure of the heavy fabric of the loaded earth and sand 16, they move in the direction of the arrow 11 in FIG. In other words, it moves in the lateral direction indicated by W of the hull, which is the direction in which the female fitting parts 6 and 4 are fitted, and creates an opening 11 in the bottom of the hopper 1 as shown in FIG. is discharged into the water from the opening 11 and dumped.On the other hand, if the upper sand 16 is not loaded, the upper sand 16
Since no pressure is generated, as shown in Figure 2 < J: [

The hydraulic cylinder 8 is used for operation with one hydraulic cylinder 8. In order to prevent the earth and sand 16 from leaking from the opening 11 when loading the earth and sand 16 into the hopper 1, it is necessary to open the right half 2A and the left half 2B of the hull as shown in Figs. A triangular protrusion 12 and a gasket 16 can be provided at the contact portion 11, respectively. In this embodiment, a cargo transport ship divided into two parts has been explained, but the present invention is not limited to this, and the purpose of the present invention is not limited to this.

It is formed into a split type, and the AJl female fitting parts provided at both ends can be slid in the lateral direction of the hull.
The advantage is that the hull can be made larger. The multi-segmented hull opens laterally, so even if the depth of the water at the place where the earth and sand is dumped is as shallow as the full load draft of the ship, the work of dumping the earth and sand can still be carried out. Furthermore, since a large number of locking devices that can tighten and open the gL female fitting part of the multi-divided hull can be provided as needed, the gap between the openings of both the left and right hulls due to hull distortion can be reduced, and the However, since contact between the gaps can be maintained through the packing and triangular protrusions, it is easy to prevent water leakage. 4 Brief description of the drawings Fig. 1 is a front view of a two-split type double feed according to an embodiment of the present invention, Fig. 2 is a front sectional view of the main part in the AA direction of Fig. 1,
