In the leak stopping method of the application, although the rapid blocking plate can block the crack at the deep water depth part on the ship body by using the water pressure, for the crack at the position close to the water surface on the ship body (for example, the crack of the ship body within 1 water from the water depth), because the water depth is shallow, the water pressure at the crack part of the ship body close to the water surface part is small, at this time, the rapid blocking plate is simply adsorbed at the crack part on the outer wall of the ship body, and the crack on the ship body is difficult to reliably block. Therefore, the existing plugging method for plugging broken holes and cracks by adsorbing the quick plugging plate on the outer wall of the ship body by using water pressure has poor effect when being applied to plugging the ship body cracks with shallow water depth, and is difficult to reliably plug the cracks on the ship body.
