Description

Inflatable plugging device based on ship damage

technical field

The invention relates to a ship application tool, in particular to an inflatable leakage plugging device based on ship damage.

Background technique

my country is a big shipping country, and the shipping industry is developing rapidly. There are also many collision accidents such as collision and grounding of ships during navigation, and it is very easy for the hull to be damaged or flooded. If the damaged loopholes cannot be blocked in time and quickly, when the damaged loopholes reach a certain level, the ship will sink into the sea, causing loss of personnel and property; in addition, the leakage of fuel oil inside the ship will pollute the ocean. At present, cork, plugging board, plugging blanket, plugging box and other utensils are generally used for plugging ship damage leaks. The above-mentioned ship leak plugging methods are complicated to operate and take a long time to plug the leaks, and it is impossible to quickly plug the leaks; at the same time, due to the limited plugging materials used and the lack of special auxiliary plugging tools, there are problems such as poor plugging, poor plugging effect, and The defect of low plugging efficiency; in addition, when the large-tonnage hull and damaged leaks are located under the deep sea, they are under great pressure from seawater, and the traditional plugging methods are difficult to ensure the success rate and low reliability of plugging.

In order to overcome the above-mentioned defects, various ship plugging devices with good applicability have been developed in the prior art. For example, the Chinese utility model patent with the authorized announcement number CN204452880U discloses a fast leak plugging device for ships, which includes a plugging baffle (4), sliding rod (7), quick clamping device (9), pull rope switch (1), binding belt (11), and the plugging baffle (4) are composed of several steel plates, and the steel plates are combined by Page connection, the plugging baffle (4) is fixedly connected on the slide bar (7), the other end of the slide bar (7) passes through the quick clamping device (9), the leak plugging baffle (4) and the quick clamp Also be connected with stay rope switch (1) between tight device (9), fast clamping device (9) is equipped with inner support baffle plate (8) from the nearer side of leak-stopping baffle plate (4). This kind of plugging device opens the plugging baffle under the action of pull rope switch, binding belt, hinge and spring, pushes the quick clamping device to block the leak from the support baffle inside the hull, and finally through the quick clamping The device fixes the support baffle to complete the plugging work. Its operation is relatively simple, but the expansion of the plugging baffle (4) is only driven by the force of the binding belt (11), the force area is small, and it is impacted and affected by the seawater pressure outside the hull during the expansion process, which requires a lot of cost. It can only be unfolded with strength, and the binding belt (11) is easy to break, resulting in the failure of the sealing work; in addition, the inner support baffle (8) has poor airtightness for sealing the leak, and cannot be seamlessly fitted according to the shape and size of the damaged leak Plug the leak, the reliability of plugging is low.
