Curtain-type leak stopper for ship cracks and leak stopping method

Abstract

The invention discloses a curtain-type leak stopper for ship cracks and a leak stopping method. The curtain-type leak stopper comprises a leak stopping framework, a winding drum arranged on one side wall of the leak stopping framework and used for contracting and releasing curtain cloth, a first pulley, a second pulley and a pull rope. The first pulley is arranged on the other side wall of the leak stopping framework corresponding to the winding drum and used for supporting the pull rod and enabling the pull rope to inwardly fold and steer. The second pulley is arranged in the middle of the leak stopping framework and used for supporting the pull rope to slide and facilitates tensioning the pull rope. One end of the pull rope is connected with the curtain cloth wound in the winding drum and the other end thereof orderly penetrates through the first pulley and the second pulley. The curtain-type leak stopper for ship cracks and the leak stopping method have the following beneficial effects: by tensioning the pull rope, the curtain cloth can be drawn out of the winding drum and covers the leak stopping framework so that the leak stopping effect is exerted; the curtain-type leak stopper is ingenious in concept, convenient in operation, timely in leak stopping operation and good in leak stopping effect and is safe and reliable; a great crack can be block timely when any ship leaks; and the curtain-type leak stopper can effectively prevent excessive water from entering a cabin so that ship sinking and great loss of cargo are prevented.

Description

technical field [0001] The invention relates to a curtain-type ship crack plugging device and a plugging method, belonging to the technical field of ship leak plugging. Background technique [0002] At present, the hull and lower part of the ship are pierced by hidden reefs during navigation, or leaks caused by collisions and other reasons need to be plugged in time, otherwise major safety problems of hull tilting will easily occur. However, some existing hull leak plugging devices have problems such as long time consumption, low efficiency, inconvenient operation, poor reliability, and inability to effectively block a large amount of water pouring into the cabin in a very short period of time. [0003] For example, a rolling-type ship plugging blanket device and its leak plugging blanket (authorized announcement number CN2635514Y), which consists of two stainless steel symmetrical brackets, the upper and lower parallel bracket fixing rods in between, and the blanket guide r...

AI Technical Summary

Problems solved by technology

From the perspective of the structure and working method of the leak stopper, it is not only complicated and bulky in structure, but also inconvenient to operate, time-consuming and laborious, and cannot achieve fast, safe and reliable plugging

[0004] For example, a quick plugging umbrella (application number 88217693.5), which consists of mandrel, umbrella cap, umbrella rib, support rod, spring, umbrella sliding sleeve, upper support ring, lower support ring, soft umbrella surface, sleeve
