Description

Technical Field

[0001] The present invention relates to the technical field of ship maintenance, and specifically to an adaptive hull rapid leak repair method. Background Art

[0002] With the development of technology and industrial production, activities such as maritime trade, fishery, oil exploration, and scientific research expeditions require regular warships to guard the vast territorial seas. In modern military affairs, large ships and warships are playing an increasingly important role in the military field. If a maritime conflict occurs during the execution of military tasks by warships, it will inevitably lead to damage to the hull of the warship. Therefore, quickly repairing the holes caused by conflicts in warships is a necessary measure to effectively avoid the expansion of losses and protect the normal navigation of warships, and it is of extremely important significance for maintaining the combat effectiveness of warships.

[0003] Currently, when there are breaches in key parts of ships, leak repair materials such as cork are mostly used for filling, with limited repair capabilities. In addition, the repair efficiency is not high. Summary of the Invention

[0004] The main purpose of the present invention is to provide an adaptive hull rapid leak repair method, aiming to improve the repair ability and repair efficiency of the hull hole area.

[0005] To achieve the above purpose, the present invention provides an adaptive hull rapid leak repair method, including the following steps:

[0006] Determine the location of the hull hole and preliminarily judge the size of the hull hole. Underwater, paste a waterproof coil made of waterproof material on the curved surface outside the hole area, and fix it at the boundary where the waterproof coil contacts the ship body;

[0007] Seal the outer boundary of the repair area formed by the waterproof coil.

[0008] Preferably, after the step of sealing the outer boundary of the repair area formed by the waterproof coil, the following steps are further included:

[0009] Pump out the water in the hull hole area and repair the hole area inside the hull.

[0010] Preferably, when repairing the hole area inside the hull, the inside of the hull is repaired by splicing or welding steel plates.

[0011] Preferably, when pasting the waterproof coil made of waterproof material on the curved surface outside the hole area underwater, an equidistant circle is used to divide the grid to determine the area where the waterproof coil needs to be pasted.

[0012] Preferably, when using an equidistant circle to divide the grid, the center of the circle is at the breach of the hole.

[0013] Preferably, when fixing the boundary where the waterproof coiled material contacts the hull, underwater laser welding is used for fixing.

[0014] Preferably, when welding the waterproof coiled material, a semiconductor laser emits laser underwater so that the laser irradiates from the side of the waterproof coiled material. A melting area is generated at the interface near the connection between the waterproof coiled material and the hull steel plate, and tiny bubbles are excited inside. The generation or expansion of the bubbles generates high pressure, causing the melted waterproof coiled material to closely adhere to the metal surface, achieving the purpose of connection.

[0015] Preferably, when sealing the outer boundary of the repair area formed by the waterproof coiled material, a waterproof coating is used to coat the outer boundary of the repair area formed by the waterproof coiled material.

[0016] Preferably, the waterproof coating is made of polyurethane waterproof coating.

[0017] Preferably, the waterproof coiled material is made of high molecular waterproof coiled material chloroprene rubber.

[0018] The self - adaptive hull rapid leak - repair method proposed by the present invention can quickly repair the situation where there is no space for repair inside the ship or it is difficult to complete the repair work, avoiding serious consequences caused by the expansion of the leak. The operation of the present invention is simple. By combining the grid division method, the best leak - repair area can be found. The leak - repair is rapid and has a good effect, and it can be self - adaptive to the size of the leak. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The realization of the purpose, functional characteristics and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] It should be noted that in the description of the present invention, the orientation or positional relationship indicated by terms such as "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention. In addition, terms such as "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0026] Referring to Figure 1 , in this preferred embodiment, an adaptive hull rapid leak repair method includes the following steps:

[0027] Step S10: Determine the location of the hull leak and preliminarily judge the size of the hull leak. Underwater, paste a waterproof coil made of waterproof material on the curved surface outside the leak area, and fix it at the boundary where the waterproof coil contacts the hull.

[0028] Step S20: Seal the peripheral boundary of the repair area formed by the waterproof coil. Paste the waterproof coil on the hull curved surface. The waterproof coil has good ductility and can adapt to curved surfaces with different curvatures. The fitting method of the hull leak break is as Figure 3 shown.

[0029] The area of the repair area needs to be larger than the area of the leak area and cover the entire leak area.

[0030] Further, after step S20, it further includes:

[0031] Step S30: Pump out the water in the hull leak area and repair the hull leak area inside the hull.

[0032] In step S30, when repairing the hull leak area inside the hull, the hull inside is repaired by splicing or welding steel plates. Splicing means connecting multiple steel plates together (sometimes it is inconvenient to carry large-sized plates, and multiple standard plates can be spliced into the required size), and then welding the spliced plates as a whole to the leak area. Welding means welding a whole steel plate to the leak area.

[0033] Using the method of welding or splicing steel plates inside the hull for repair further enhances the reliability of the repair.

[0034] When there are holes in the hull of a ship, there are two situations. When there is space inside and it is convenient to carry out repairs, this method can be used to repair outside the ship. After eliminating the influence of the water pressure inside and outside the ship, it is easier to complete the hole repair work inside the ship. The hole can be repaired by splicing or welding steel plates inside the ship. However, inevitably, the hull hole occurs in a position where there is no space for repair inside or the repair tools inside the ship are not easy to operate. Through the method of the present invention, it can adapt to the size of the hole and make the waterproof coiled material better fit the curved surface by laser welding, and carry out edge sealing treatment on the surrounded area of each point determined by the method of grid division to achieve the purpose of rapid repair.

[0035] Referring to Figure 2 and Figure 3 , in step S10, when determining the location of the hull hole, find the location of the hull hole of the ship according to the internal alarm of the ship. When pasting the waterproof coiled material made of waterproof material on the curved surface outside the hole area underwater, the method of using equally spaced circles for grid division is adopted to determine the area where the waterproof coiled material needs to be pasted. When using equally spaced circles for grid division, the center of the circle is at the break of the hole. The schematic diagram of using equally spaced circles for grid division is shown in Figure 2 , Figure 2 . In

[0036] , with the break of the hole as the center of the circle, four circles are divided. The diameter difference between adjacent two circles is equal, that is, equally spaced circles. Determine the equally spaced circles according to the hole area, and it is necessary to make the area of each sector region cover the hole area.

[0037] In step S10, when fixing the boundary where the waterproof coiled material contacts the ship's hull, underwater laser welding is used for fixing.

[0038] Referring to Figure 3 , when welding the waterproof coiled material, the semiconductor laser emits laser underwater so that the laser irradiates from the side of the waterproof coiled material. A melting area is generated at the adjacent connection interface between the waterproof coiled material and the hull steel plate, and tiny bubbles are excited inside. The generation or expansion of the bubbles generates high pressure to make the melted waterproof coiled material closely adhere to the metal surface to achieve the purpose of connection.

[0039] In step S20, when carrying out edge sealing treatment on the outer boundary of the repair area formed by the waterproof coiled material, use waterproof paint to brush the outer boundary of the repair area formed by the waterproof coiled material.

[0040] In this embodiment, it is preferred that the waterproof coating is made of polyurethane waterproof coating. The specific reasons for the waterproof coating being polyurethane waterproof coating are as follows: 1. Polyurethane waterproof coating can be constructed on wet base surfaces; 2. It has a strong adhesion to the base surface and can be used for bonding some polymer membranes; 3. It is green and environmentally friendly without polluting the environment; 4. It has high strength, good elasticity, good weather resistance, good waterproof performance, wear resistance, and acid and alkali resistance.

[0041] The waterproof membrane is made of neoprene, a synthetic polymer waterproof membrane. The specific reasons for the waterproof membrane being neoprene are as follows: 1. The polymer waterproof membrane has excellent elasticity and tensile strength and strong adaptability to the deformation of the base layer; 2. It has excellent weather resistance, enabling the membrane to have a longer service life under normal maintenance conditions and reducing the costs of maintenance and renovation.

[0042] The self-adaptive rapid leak repair method for ship hulls proposed by the present invention can quickly repair the situation where there is no space for repair or it is difficult to complete the repair work inside the ship, avoiding serious consequences caused by the expansion of the leak. The operation of the present invention is simple. By combining with the grid division method, the best leak repair area can be found. The leak repair is rapid and the leak repair effect is good, and it can be self-adaptive to the size of the leak.

[0043] The above are only the preferred embodiments of the present invention and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
