Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a watertight device for a hatch cover provided on a ship, and more particularly to a rubber for repairing a packing.

[0002]

[Prior Art]

 The hatch cover provided in the hold of the ship has a watertight structure to prevent intrusion of seawater and rainwater. For example, as shown in FIG. 3, between the hatch cover 4 and the hatch coaming 6 that open and close the hold 7. The tightening bar 3 protruding from the hatch coaming 6 and the packing 1 formed of an elastic body fixed to the hatch cover bottom plate 40 are brought into close contact with each other by the fastening metal fitting 5 and the lock lever 51, and seawater or rainwater enters the hold 7. A structure is known to prevent this.

[0003]

[Problems to be solved by the device]

 The packing 1 is always in close contact with the tightening bar 3 while the ship is sailing, and the packing 1 causes friction with the tightening bar 3 when the hatch cover 4 is opened and closed. As shown in, the permanent deformation portion 12 formed of a recessed portion having a loss of elasticity is formed in the base portion 10 of the packing 1 that contacts the tightening bar 3 and the seal member 11.

When the permanent deformation part 12 is generated in the packing 1, a gap is created between the tightening bar 3 and the packing 1 when the hatch cover 4 is closed, and the watertight performance is deteriorated, so that seawater or rainwater enters the hold 7. .. Therefore, in order to recover the watertight performance, the packing 1 having the permanently deformed portion 12 is removed from the hatch cover bottom portion 40, and a new packing 1 is fixed again for replacement.

However, there has been a problem that the packing repair work requires a great number of man-hours and costs.

Therefore, an object of the present invention is to provide a watertight device capable of easily and inexpensively repairing a packing of a hatch cover that has been permanently deformed due to aging or the like.

[0007]

[Means for Solving the Problems]

 The present invention is formed of an elastic body that is fixed to the hatch cover that covers the hatch opening of the deck so that it can be opened and closed, the tightening bar that projects along the periphery of the hatch opening, and the hatch cover that faces the tightening bar. Formed of a rod-shaped elastic body having a fixed packing, a permanent deformation portion of the packing formed at the abutting portion of the tightening bar, and a convex portion of a predetermined height fitted and bonded to the permanent deformation portion. Equipped with repaired rubber.

[0008]

[Action]

 When the hatch cover is closed, the repair rubber that is fitted and fixed to the permanent deformation part of the packing comes into contact with the tightening bar, and the repair rubber deforms according to the pressure of this contact and adheres tightly to the tightening bar. To do.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a packing adhered and fixed to a hatch cover (not shown) that abuts a tightening bar (not shown). The base 10 is formed of a rectangular elastic body, and is fixed to the base 10. The seal member 11 is formed of an elastic body.

Reference numeral 12 denotes a permanently deformed portion that comes into contact with a tightening bar (not shown) and loses elasticity due to secular change to become a concave portion. It maintains the same recess as when it abuts the ning bar.

The base 10 is made of sponge rubber as an example, and the seal member 11 is made of neoprene sheet as an example.

Reference numeral 2 is a repair rubber formed of a rod-shaped elastic body and formed in a predetermined shape to fit into the permanent deformation portion 12, and 21 is a packing 1 having a shape equal to the curvature of the concave portion of the permanent deformation portion 12. In the abutting convex portion, the height of the convex portion 21 is substantially equal to the depth of the permanent deformable portion 12, and 22 is a flat portion that is a surface that abuts a not shown tightening bar.

The repair rubber 2 is formed of a neoprene sheet, for example.

When the convex portion 21 of the repair rubber 2 is fitted along the permanent deformation portion 12 of the packing 1 and fixed by an adhesive means such as an adhesive, the packing 1 and the repair rubber 2 are integrated, and the seal member 11 and the flat portion 22 form a surface having substantially the same height.

With the above-mentioned configuration, the operation will be described.

When the packing 1 is brought into contact with a tightening bar (not shown) (see FIG. 3), the flat portion 22 of the repair rubber 2 comes into contact with the tightening bar. At this time, the repair rubber 2 is deformed according to the abutting pressure and adheres to the tightening bar to form a watertight structure.

The permanent deformation portion 12 generated in the base portion 10 and the seal member 11 of the packing 1 loses elasticity, but when the repair rubber 2 is fitted and fixed to the permanent deformation portion 12 by an adhesive means, The elasticity of the repair rubber 2 can restore the watertight function again.

Therefore, even if the permanent deformation portion 12 is generated in the packing 1 due to secular change or the like, and the watertight function is deteriorated, the watertight function can be restored only by fixing the repair rubber 2 to the permanent deformation portion 12, and a special skill can be obtained. It is possible to easily and inexpensively repair the packing 1 without requiring the operation.

[0020]

[Effect of the device]

 As described above, according to the present invention, the watertight function can be restored by simply fixing the repair rubber to the permanent deformation portion of the packing without removing and replacing the packing having the permanent deformation portion. The packing can be repaired easily and inexpensively without requiring skill, and the time required for the repair can be shortened.
