Combined leakage stoppage mat

Abstract

The invention relates to a combined leakage stoppage mat. The combined leakage stoppage mat is characterized in that the combined leakage stoppage mat comprises a leakage stoppage cushion, a leakage stoppage base plate and an end cover. A stepped camshaft is arranged on the inner side of the leakage stoppage base plate, and the cross section of the stepped camshaft is in an inverted-T shape. A round hole is formed in the center of the leakage stoppage base plate. A round hole is formed in the center of the leakage stoppage cushion. The leakage stoppage cushion is arranged on the camshaft of the leakage stoppage base plate in a penetrating mode. The combined leakage stoppage mat is formed by the leakage stoppage cushion, the leakage stoppage base plate and the end cover. The combined leakage stoppage mat has the beneficial effects that the leakage stoppage cushion and the leakage stoppage base plate are combined for use, so that the complex process that a leakage stoppage cushion and a board are temporarily combined for leakage stoppage is simplified; in addition, the leakage stoppage cushion can also be disassembled quite conveniently to be applied to other leakage stoppage occasions, and the applicability is improved; and the combined leakage stoppage mat can be used for blocking a small hole of a inward folded edge or an outward folded edge and can be used in cooperation with the auxiliary appliances such as a movable screw frame, a telescopic supporting column and a rib supporting frame, and the application occasions are widened.

Description

technical field [0001] The invention belongs to leak-stopping equipment for ships, in particular to a combined leak-stopping pad. Background technique [0002] Hull damage is a common and important form of ship damage that may cause great harm. After damage occurs, a large amount of seawater is poured into the hull. If the range of water ingress cannot be controlled, the seawater will flow and increase arbitrarily, which will cause the ship to tilt, reduce buoyancy, and even capsize or sink. Hull plugging is to control the degree of damage after the hull is damaged. Various equipment and tools are used to block the breaches, loopholes and cracks to prevent seawater from entering. The existing ship plugging equipment at home and abroad mainly include soft-sided plugging boards, plugging cushions, plugging boxes, loose-leaf plugging boards, plugging umbrellas, air plugging bags, plugging blankets, wooden plugs, wooden wedges, etc. In addition, there are auxiliary equipment f...

Problems solved by technology

However, when the plugging cushion with holes is used in conjunction with the movable screw frame, the thread of the movable screw frame often scratches the fabric at the hole, and the wadding in the cushion is easy to wrap around the thread after being exposed, making the thread fit place impossible. Rotate, the plugging cushion cannot be compressed, often resulting in plugging failure
