Description

Technical Field

[0001] The invention belongs to the technical field of vehicle transport ships, and in particular relates to a blocking device. Background Art

[0002] Vehicle transport ships include multiple decks, each deck is provided with lashing holes for tying vehicles. According to the construction specifications, car transport ships are equipped with fire partitions every 2-3 decks, and the lashing holes involving fire partitions need to be equipped with lashing bowls. Car transport ships that can carry 7,000 cars have more than 70,000 lashing bowls per ship, and the sum of the number of lashing bowls and lashing holes is more than twice the number of lashing bowls. The lashing bowls are welded on the sections, and the sandblasting and painting are completed in the section painting stage. They also go through the general section assembly, dock loading and dock commissioning stages. Because there are no perfect and effective protection measures, water, debris, dust, etc. enter the lashing bowls during the construction process at each stage after the painting is completed, forming a mixture of garbage and water. Some are hard and difficult to clean up later. In the later stage of ship construction, especially during the period close to sea trials and delivery, a large amount of manpower is required to clean the mixture of garbage and water in the lashing holes. Many factors such as tight construction period, wide area, and large number are intertwined, becoming one of the main contradictions before delivery.

[0003] At present, the following measures are mainly used to seal the binding holes: filling with rags, sealing with plastic covers, filling with sponges, filling with rubber and sponges, and using rags and plastic covers together. Filling with rags is not waterproof, and the rags themselves become garbage over time, posing a fire hazard. When using plastic covers for sealing, due to the different hole diameters, the unified plastic sealing tooling either cannot cover the hole or is easy to fall off. Some are barely installed, and it is laborious and time-consuming to remove, and they are not waterproof. Filling with sponges is not waterproof and is easy to fall off, similar to rags. When using sponges for sealing, a rubber is set on the top of the sponge. This measure is not sufficiently sealed, and water and debris still enter. When using rags and plastic covers together, the plastic cover is not easy to buckle or is easy to fall off, it is easy to get water in, and it is difficult to disassemble and assemble.

[0004] Based on the above situation, there is an urgent need to provide a blocking device. Summary of the invention

[0005] The embodiment of the present invention provides a sealing device, which can accommodate the error of the lashing hole diameter and seal the lashing hole, so that there is a closed space between the lashing bowl and the deck, and can be easily installed or disassembled from the lashing hole with good sealing performance.
