Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more specifically to a method for paint protection of detachable hull plates. Background Technology

[0002] During the dock assembly and outfitting process, the ship's construction environment is complex and there are many overlapping operations. Oil stains, sewage and other pollutants will be generated on the deck surface. The oil stains and sewage are discharged from the hull plate drain pipe openings in the bottom or freeboard area through the drainage holes set on the deck surface. The discharged oil stains and sewage flow down the hull plate, causing pollution to the hull plate coating, increasing the workload of hull plate grinding and rust removal, and in more serious cases, it will lead to the rework of the hull plate paint.

[0003] Currently, common methods for guiding sewage away from the hull involve welding an arc-shaped steel plate below the side pipe, or using plastic hoses. However, the method of using welded semi-circular pipes requires prefabricating arc-shaped steel plates, which must be cut off before final delivery. The cut semi-circular pipes have imperfections at the edges, making them unsuitable for reuse and costly. Furthermore, welding on the hull plating area causes paint damage, which is repeated during the subsequent cutting process, requiring repainting and refinishing. Cutting the semi-circular pipes offshore requires a crane, making the entire process cumbersome, labor-intensive, and dangerous, consuming significant manpower and resources. When using plastic hoses, the softness of the plastic makes the extended ends prone to deformation and difficult to secure, causing sewage to flow down the hull plating and failing to provide effective drainage.

[0004] Therefore, there is an urgent need to propose a detachable hull plating paint protection method to ensure the effectiveness, economy and convenience of hull plating coating protection, and to effectively avoid pollution and damage to the hull plating coating. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a detachable method for protecting the paint on the hull of a ship, effectively ensuring the effectiveness of the method, the economy of the protective device, and the convenience of the protective operation, while avoiding the waste of manpower and resources.

[0006] The technical solution adopted in this invention is: A method for painting protection of detachable hull plates includes the following steps: Step 1: Prepare galvanized sheet metal rolled into pipes; Step 2: Fix the galvanized sheet metal rolled pipe; Step 3: Install the galvanized sheet metal rolled pipe; Step 4: Disassemble the galvanized sheet metal rolled pipe; Step 5: Recycle galvanized iron sheets to make pipes.

[0007] Preferably, in step 1, the diameter of the galvanized sheet metal rolled tube is set according to the diameter of the outer pipe of the hull, galvanized sheet metal is selected, and the galvanized sheet metal is rolled into a round tube along the length direction of the galvanized sheet metal to obtain the galvanized sheet metal rolled tube.

[0008] Preferably, the length of the galvanized sheet metal rolled tube is not less than 500 mm.

[0009] Preferably, in step 2, after the galvanized sheet metal rolled pipe is inserted into the outer pipe of the blasting hull and connected with the pipe opening of the outer pipe, a pair of hose clamp fasteners are used to fix the galvanized sheet metal rolled pipe.

[0010] Preferably, the hose clamp fastener on the side closer to the outer tube of the bleacher is called the near hose clamp fastener, and the hose clamp fastener on the side farther from the outer tube of the bleacher is called the far hose clamp fastener.

[0011] Preferably, in step 3, glass glue is evenly applied to the pipe opening of the outer hull pipe, the galvanized iron sheet rolled pipe is connected to the pipe opening of the outer hull pipe and pressed tightly, and the galvanized iron sheet rolled pipe is fixed with a nylon rope. The nylon rope is in a straight state, with one end fixed to the far throat clamp fastener and the other end fixed to the side railing of the deck.

[0012] Preferably, in step 4, a galvanized sheet metal rolled pipe is used to discharge sewage. After the entire ship construction is completed, the galvanized sheet metal rolled pipe is struck with a steel pipe to separate the galvanized sheet metal rolled pipe from the outlet pipe.

[0013] Preferably, in step 5, the galvanized sheet metal rolled pipe is recovered using a nylon rope. The galvanized sheet metal rolled pipe is pulled onto the deck, the nylon rope and hose clamp fasteners fixed to the galvanized sheet metal rolled pipe are removed, and the galvanized sheet metal rolled pipe is unfolded back into galvanized sheet metal, thus completing the recovery of the galvanized sheet metal rolled pipe.

[0014] The beneficial effects of this invention are as follows: (1) The method of the present invention obtains a galvanized galvanized sheet rolled tube by rolling galvanized sheet into a round tube, and uses the galvanized sheet rolled tube to guide deck sewage, which shortens the preparation time of the deck sewage diversion device, and the galvanized sheet rolled tube can be reused, which greatly reduces the manufacturing cost of the deck sewage diversion device.

[0015] (2) The method of the present invention uses hose clamp fasteners to fix galvanized iron sheet, which makes it easy to adjust the diameter of the rolled pipe of galvanized iron sheet. It is suitable for docking outboard pipes of different sizes, and the galvanized iron sheet can be recycled and reused, which enhances the applicability of rolled pipe of galvanized iron sheet.

[0016] (3) The present invention uses glass glue to fix the galvanized iron sheet rolled pipe at the pipe opening of the outer side pipe. No welding or cutting operations are required during installation and disassembly, which effectively avoids rework caused by coating damage.

[0017] (4) The present invention uses nylon rope to connect the hose clamp fastener and the deck side railing, which reduces the risk of galvanized iron sheet rolled pipe falling off and will not damage the coating on the deck side railing. At the same time, the present invention also uses nylon rope to realize the rapid recycling of galvanized iron sheet rolled pipe, effectively reducing the difficulty of recycling galvanized iron sheet rolled pipe.

To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] The present invention will now be described in detail with reference to the accompanying drawings: This embodiment proposes a method for paint protection of detachable hull plates, including the following steps: Step 1: Prepare galvanized sheet metal rolled pipe.

[0025] In this embodiment, the diameter of the galvanized iron sheet rolled tube is set according to the diameter of the outer pipe of the hull. A galvanized iron sheet 1 with dimensions of 1000mm×1000mm×1mm is selected to make a galvanized iron sheet rolled tube 2. The galvanized iron sheet 1 is rolled along its length to form a round tube, resulting in a galvanized iron sheet rolled tube 2 with a length of not less than 500mm. Figure 1 As shown.

[0026] Step 2: Fix the galvanized sheet metal rolled pipe.

[0027] In this embodiment, the galvanized sheet metal rolled pipe 2 is inserted into the outer hull pipe 3 of the hull hull plating 6. After docking with the pipe opening of the outer hull pipe 3, a pair of hose clamp fasteners 4 are used to fix the galvanized sheet metal rolled pipe to the hull hull plating 6. Figure 2 As shown, the hose clamp fasteners on the side closer to the outer hull tube are called near-hose clamp fasteners, and the hose clamp fasteners on the side farther from the outer hull tube are called far-hose clamp fasteners.

[0028] Step 3: Install the galvanized sheet metal rolled pipe.

[0029] In this embodiment, a small amount of silicone sealant 5 is evenly applied to the opening of the outer hull pipe, and the galvanized sheet metal rolled pipe 2 is connected to and pressed tightly to the opening of the outer hull pipe 3. Figure 3 As shown, galvanized sheet metal coiled pipe 2 is fixed with nylon rope 7. The nylon rope is in a taut state, with one end fixed to the far throat clamp fastener and the other end fixed to the side railing 9 of the deck 8. Figure 4 As shown.

[0030] Step 4: Disassemble the galvanized sheet metal rolled pipe.

[0031] In this embodiment, a galvanized sheet metal rolled pipe is used to discharge sewage. After the entire ship is constructed, the galvanized sheet metal rolled pipe is struck with a steel pipe to separate the galvanized sheet metal rolled pipe 2 from the outlet pipe 3. The galvanized sheet metal rolled pipe is then removed from the outlet pipe 3, thereby removing the galvanized sheet metal rolled pipe from the outer hull plate 6.

[0032] Step 5: Recycle galvanized iron sheets to make pipes.

[0033] In this embodiment, the galvanized iron sheet rolled tube 2 is recovered using nylon rope 7. The galvanized iron sheet rolled tube is pulled to the deck 8, and the nylon rope 7 and hose clamp fastener 4 fixed to the galvanized iron sheet rolled tube 2 are removed. The galvanized iron sheet rolled tube is then unfolded back into galvanized iron sheet, thus completing the recovery of the galvanized iron sheet rolled tube.

[0034] Meanwhile, the galvanized iron sheet recovered in this embodiment can be reused to prepare galvanized iron sheet rolled pipes, which can be applied to the paint protection of the ship's outer plating, thus realizing the reuse of the paint protection device for the ship's outer plating.

[0035] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
