Abstract

PURPOSE:To protect the water-tight mechanism from breaking upon rolling of hull, by providing a barrier belt of plastic on the under face of a hold cover while adjoining the edge of gasket such that the lower edge will contact with the upper face of horizontal member of hold edge member. CONSTITUTION:An elongated barrier belt 5 is provided on the under face of hold cover panel 2 while adjoining to the inner edge of gaskets 3a, 3b for constructing the water-tight system of hull cover. Said barrier 5 is composed of non-sparkable material such as copper alloy or plastic where the lower edge is contacted against the upper face of horizontal member 1H at the upper end of hold edge member 1. Consequently, the gasket can be protected from damage due to the hold cover panel 2 upon rolling of hull.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a watertight device for a rudder hatch, and more specifically, the present invention relates to a watertight device for a rudder hatch, and more specifically, to a watertight device for a rudder hatch, and more particularly, to a top surface of a horizontal member located at the upper end of a hull rim, and a bottom outer circumferential portion of a hull hatch panel placed in a closed position. It relates to a device for watertightly sealing the gap formed between the two.

The upper surface of the horizontal member located at the upper end of the rudder edge material and the closed position V
The conventional water supply device that seals the gap between the outer peripheral part of the lower surface of the rudder port cover panel attached to the rudder port panel is equipped with a gasket made of rubber that does not allow water, oil, etc. to permeate and is attached to the lower surface of the rudder port panel VC, with an appropriate degree of compression. 10 It is crimped onto the upper edge of the compression bar that protrudes upward from the horizontal side of the upper edge of the edge material to seal the contact surface between the two.The rubber material used as the gasket is appropriately selected and the material Assuming that it is not only impermeable to water or oil, but also sufficiently resistant to oil erosion, in the case of a rudder rim with a relatively narrow opening, Generally satisfactory results have been obtained. However, in some of the new ship shapes adopted in recent bulk carriers, the width of one port is extremely widened, and the width is the same as the width of the age of the ship. With such a wide port, a large amount of water such as ballast or cargo oil located inside the rudder port rim material applies impact to the 1il11 edge portion of the rudder port cover with a large amount of momentum when the ship is rocking. It is not possible to achieve a complete watertight seal simply by pressing the gasket with an excessive amount of compression to the compression bar at the upper end of the rudder edge material and chaining the contact surface between the two. Therefore, a need has arisen for protective equipment to prevent these interference waves from being applied directly to the torpedo system.

The present invention seeks to solve this ridge problem that occurs in ten lids that are defeated by wide m1 openings.

An object of the present invention is to provide a mechanism for preventing direct impact from being applied to the gasket due to the momentum of ballast or cargo oil moving inside the rudder edge member during the movement of the ship. It is possible to obtain a watertight device for the dawn palate leading to a particularly wide rudder port with a locking mechanism.

According to the present invention, a compression/degree bar protrudes upward from the upper surface of the horizontal member located at the upper end of the rudder edge member, and a compression/degree bar that is attached to the outer circumferential portion of the lower surface of the lid panel. A watertight device for the lid, comprising a gasket that requires pressure, and is installed vertically on the lower surface of the palatine panel adjacent to the inner edge of the pressure socket, and is attached to the lower edge of the lid. A slit made of copper alloy, plastic, or other material that does not generate sparks between the horizontal member and the horizontal member, which extends parallel to the slit and contacts the upper surface of the horizontal member at the upper end of the slit. A 10-lid watertight device is obtained, characterized in that it is equipped with a band-shaped barrier 5.

Now, an embodiment of the apparatus of the present invention will be described below with reference to the accompanying drawings.

Referring to Figures 1 and 2, a longitudinal bulkhead 23 is installed inside 1 of the outer skin 24, and the side coaming of the rudder edge material 1 that is attached to the deck 21 is A hull 20, such as a bulk gear, is shown with a bay 13 having an unusually wide width B located in the same vertical column as the bulkhead 23.

As shown in Figure 3, the hull 20 is 22 years old and is loaded with ballast or crude oil 14 during a voyage (from the upright position shown by the dotted chain line to the right of the line of fire due to sea waves). (J5.1 A large amount of ballast or crude oil located inside the mouth rim material 1 or at the upper end of the ship's age 22 moved to the starboard side 1.

It is provided with a barrier 5 consisting of a belt-shaped elongated vertical plate with +4y attached. The barrier 5 is made of a steel alloy or plastic material that does not generate sparks when it comes into contact with steel, and has a Hl: 1 piece, 1 stone piece, and an assembly plate panel 2 at the upper end.

The gasket 8α extends parallel to the gasket 8α with its lower end brought into contact with the upper surface of the top horizontal portion IH of the port edge member 1.

Barrier 51 construction Based on the movement of ballast or cargo oil that moves inside the rudder edge material 1 when the hull 20 moves, the barrier 51 has a thickness thick enough to withstand impact, and its lower end is connected horizontally to the top of the rudder edge material 1. Although it is slid along 1liJvC above the member IH, no sparks are generated. The flat iron member 7α to which the barrier 5 is attached is straightened on the extension line of the side coaming IS or end coaming IEl/) of the loading opening edge 1, and also serves as a partition plate constituting the socket 8a that accommodates the gasket 8a.

At the right end of the bottom plate 2B of the bottom plate 2B of the panel, there is a copper alloy/plastic scoop placed at predetermined intervals and a stool made of a material that does not generate sparks. It is designed to support the broken support block 11. Of the two rows of gaskets 8α and 8i3, the inner gasket 8a is mainly used to support the gap between the opening edge material 1 and the 1iiiD lid 2. The outer gasket 8h&''!, 1I4- is used to hold the retainer.

As described above, according to the present invention, the gaskets 8a and 8b and the compression bar 4a,
Since the watertight mechanism consisting of 4 h protects against the impact of moving ballast or cargo oil on the 10 edge side 1 (17) 179 part when the ship shakes, the water-tight side chain mechanism receives direct damage. There isn't.
