Problems solved by technology

In the plugging method of this application, although the fast plugging plate can block the cracks in the deeper parts of the hull by using water pressure, but for the cracks on the hull near the water surface (such as hull cracks within 1 water depth), due to The water depth is shallow, and the water pressure at the cracks of the hull near the water surface is small. At this time, simply adsorbing the quick-sealing plate to the cracks on the outer wall of the hull will not be able to reliably seal the cracks on the hull
It can be seen that the current plugging method of using water pressure to adsorb the quick-sealing plate on the outer wall of the hull to seal holes and cracks is not effective when it is applied to the hull cracks with shallow water depth, and it is difficult to seal them reliably. plugging the cracks in the hull

specific Embodiment 1

[0039] Specific embodiment one: as figure 1 , figure 2 As shown, a leakage plugging device for hull cracks includes a support assembly 1 and a rubber plugging member 2 . The support assembly is a plurality of support members 1.1 that are sequentially hinged and connected. A first magnetic part 1.2 is provided on the supporting part, and the supporting part is adsorbed and fixed on the outer wall surface of the hull 3 through the first magnetic part, and each supporting part is sequentially distributed on the outer wall surface of the hull from top to bottom. The support member is provided with a limit groove 1.3 with an opening facing the outer wall of the hull, and the limit groove extends up and down and runs through the support member.

[0040] The rubber plugging member 2 includes a rubber sealing belt 2.1 connected to the support assembly and extending up and down, and a sealed inner cavity 2.3 arranged in the rubber sealing belt and extending up and down. In this em...

Abstract

The invention discloses a hull crack leakage blocking device and a leakage blocking method, and aims to provide the hull crack leakage blocking device which can effectively block hull cracks at partsat the relatively small water depth of a hull by the aid of hydraulic pressure and the leakage blocking method. The hull crack leakage blocking device comprises a supporting component and a rubber leakage blocking piece; the supporting component comprises a plurality of supporting pieces connected sequentially in a hinged manner; the supporting pieces are fixed to the surface of the outer wall ofthe hull through first magnetic pieces in an attraction manner and are distributed sequentially from top to bottom; limiting grooves with openings facing the outer wall of the hull are formed in the supporting pieces; the rubber leakage blocking piece comprises a rubber sealing belt which is connected with the supporting component and is distributed in an up-and-down extending manner and a closedinner cavity which is formed in the rubber sealing belt and extends up and down; the upper part of the rubber sealing belt is accommodated in the limiting grooves; the lower part of the rubber sealingbelt is located below the supporting component; and the lower end of the rubber sealing belt extends downwards to the set depth along the outer wall of the hull.

Description

technical field [0001] The invention relates to a leak-stopping device, in particular to a leak-stopping device and a leak-stopping method for hull cracks. Background technique [0002] During the voyage of the ship, the hull may have cracks or holes due to collisions and other reasons, and it is necessary to plug the cracks or holes in the hull in time, otherwise the hull will easily cause safety problems such as tilting the hull or even sinking due to water pouring into the cabin; but Since underwater leak plugging needs to overcome water pressure, the current underwater leak plugging of the hull is not effective. [0003] In order to solve this problem, some inventors have made improvements. For example, Chinese Patent Publication No. CN102320359B, the name of the invention is the ship crawler type quick-blocking plate, which includes thin plates connected in a straight line, and between two adjacent thin plates Hinged, so as to form a crawler form as a whole; one side o...
