Description

Technical Field

[0001] The present application relates to the technical field of underwater ship maintenance, and in particular to a watertight compartment for underwater ship maintenance. Background Art

[0002] Underwater ship maintenance is essential to ensure the safe operation of ships. Ship maintenance has long been a key link in maritime transportation and marine engineering, especially when facing ocean-going ships and large ships exposed to seawater for a long time, wear and corrosion on the hull surface are often inevitable. In order to extend the service life of ships and maintain normal operations, efficient underwater maintenance methods have become an urgent need. In recent years, with the rapid development of the marine economy, higher requirements have been placed on the maintenance and overhaul technology of ships and their related facilities, which not only require high efficiency, but also need to be able to minimize the impact of maintenance activities on operations while ensuring operational safety.

[0003] The existing underwater ship maintenance technology mainly includes several common measures, such as direct water operation by divers, use of floating platforms, use of mobile watertight compartments or installation of fixed underwater work compartments for local isolation. Among them, although the manual maintenance method of divers is simple, it is not only labor-intensive but also faces high safety risks because the operators are directly exposed to the harsh environment. Although the use of temporary water platforms can improve the working environment to a certain extent, this method is often subject to the limitations of on-site conditions, and the construction time is long and the cost is high. For mobile watertight compartments, the length of the connecting compartment in the traditional watertight compartment design is usually preset in advance, and the distance between the maintenance compartment and the hull cannot be adjusted according to actual needs, resulting in the need to customize the connecting compartment before each maintenance, resulting in a waste of resources. In addition, there is also a dedicated workstation to complete the repair work in a specific area. Although this approach improves the safety and accuracy of the operation, it is limited by its own fixed position and is not flexible.

[0004] However, the above-mentioned methods generally have certain limitations. For example, temporary structures may not be able to respond quickly to changing sea conditions, resulting in extended construction periods and unnecessary expenses. For those relatively permanent facilities, the degree of support for ships of different sizes and shapes may be inconsistent due to their size design or location layout, which in turn affects the schedule and technical implementation of the entire maintenance project. In addition, no matter which type of method is used, when facing deeper waters or places with faster flow rates, how to ensure that external water flow interference can be effectively blocked while accurately locating the damaged parts becomes a thorny problem, which directly affects the quality and reliability of subsequent repair work. Especially for mobile watertight compartments, the problem that the connecting compartment cannot flexibly adjust the length makes it difficult for existing technologies to provide a solution that can adapt to a variety of ship types and quickly respond to complex environmental changes.

[0049] Reference Figure 1 and Figure 4 An upper access door 11 is provided on the top of the maintenance chamber 1, and a side access door 12 is provided between the maintenance chamber 1 and the connection chamber 2. Before the maintenance chamber 1 is launched into the water, maintenance personnel can enter the maintenance chamber 1 through the upper access door 11. After the connection chamber 2 is positioned, sealed, fixed and drained, maintenance personnel can open the side access door 12 to enter the connection chamber 2 to repair the hull.

[0050] A controller is also provided in the maintenance chamber 1. The electrical control equipment of the overall watertight chamber includes a first telescopic rod 41, a second telescopic rod 61, a first air pump 67, a second air pump 60, a third telescopic rod 52, a vacuum pump 56, a water pump 22, a one-way water valve 23, an air valve 25 and a drain valve 32, all of which are electrically connected to the controller, and the start and shutdown of these electrical control equipment can be controlled by the controller.

[0051] The implementation principle of a ship underwater maintenance watertight compartment in the embodiment of the present application is: When the watertight compartment is working, the repair compartment 1 is first lifted by the lifting cable 71 and the lifting ring 72, and then put into the sea water and moved to a position close to the hull that needs to be repaired.

[0052] When positioning the repair chamber 1, the repair chamber 1 is first moved to the height corresponding to the position where the hull needs to be repaired through the suspension cable 71, and then the third telescopic rod 52 is started to extend, driving the positioning block 53 to move toward the direction close to the hull, so that the adsorption block 54 can be adsorbed on the hull, so that the repair chamber 1 can be initially positioned at the position where the repair needs to be repaired. When the repair chamber 1 is initially positioned by the adsorption block 54, the vacuum suction cup 55 is also adsorbed onto the surface of the hull, and then the vacuum pump 56 is started to evacuate the vacuum suction cup 55 to enhance the stability of the initial positioning.

[0053] After the maintenance cabin 1 is initially positioned, the first telescopic rod 41 is started to extend, driving the adjustment cabin 42 to move, so that the adjustment cabin 42 moves to a position close to the hull.

[0054] After the regulating chamber 42 is adjusted to a suitable position, the second air pump 60 is started to adjust the second sealing airbag 69 to an inflated state, so that a sealing structure is formed between the connecting chamber 2 and the regulating chamber 42 .

[0055] After adjusting and sealing the position of the adjustment chamber 42, the second telescopic rod 61 is started to drive the fixing block 62 and the sealing strip 63 to move toward the direction close to the hull, so that the sealing strip 63 can form a tight fit with the hull under the action of its own deformable material. When the second telescopic rod 61 is extended, it drives the sealing strip 63 to move toward the direction close to the hull, while driving the sealing chamber 64 to move toward the direction close to the hull, which can further increase the length of the connection chamber 2; when the sealing strip 63 is in close contact with the surface of the hull, the first air pump 67 is started to adjust the first sealing airbag 66 to the inflated state, so that a sealing structure is formed between the sealing chamber 64 and the adjustment chamber 42.

[0056] After the connection chamber 2 is positioned and sealed, the watertight chamber is fixed by the steel cable 81, and the tension of the steel cable 81 is adjusted by the basket bolt 82 to ensure the stability and reliability of the entire watertight chamber.

[0057] After the connection chamber 2 is positioned and sealed, the water pump 22 is started and the one-way water valve 23 and the air valve 25 are opened, so that the seawater in the connection chamber 2 flows into the drainage chamber 3 and the air in the drainage chamber 3 enters the connection chamber 2 .

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
