Description

Technical Field

[0001] This invention relates to the field of marine platform and ship engineering technology, specifically a temporary sealing device and method for electrical penetration holes in ships. Background Technology

[0002] In the construction of offshore platforms and ships, bulkheads and decks, as key structural components, can divide the interior of the ship into multiple functional areas, such as cargo storage areas, crew living quarters, and power equipment rooms, so that each area is functionally independent and does not interfere with each other. On the other hand, they undertake the important task of providing structural strength and play an irreplaceable role in resisting the impact of sea waves and ensuring the stability of the ship.

[0003] Because electrical equipment installation typically lags behind structural construction, the electrical penetration test (MCT) is often not yet installed when pressure water and air tightness tests are required for the compartment. This hinders the normal progress of the tests, as the lack of the MCT prevents the compartment from forming a completely sealed space for effective testing, thus preventing the tests from proceeding smoothly. Traditional methods use high-value filling materials to temporarily seal relevant areas, but these materials have very little value for reuse after the test, resulting in resource waste. Therefore, a new, efficient, and reliable temporary sealing method is urgently needed. Summary of the Invention

[0004] To address the problem of traditional methods using high-value filling materials for temporary sealing, which result in poor material reuse and resource waste, this invention provides a temporary sealing device and method for ship electrical penetration holes. In this invention, each sealing module's cross-section and modular clamping plate has at least one right angle. This facilitates direct splicing of the sealing modules. When multiple sealing modules of different shapes abut against each other at their right angles, gaps are avoided, achieving seamless splicing to ensure the tightness of the temporary sealing. Furthermore, the modular clamping plate, sealing modules, and back clamping plate are connected by bolts and nuts, facilitating disassembly and reassembly, and enabling the reuse of the sealing modules, thus avoiding resource waste caused by difficulty in reusing them.

[0005] The technical solution adopted in this invention is:

[0006] A temporary sealing device for electrical penetration holes in ships includes several sealing modules of different shapes, modular clamps with the same cross-sectional shape as the sealing modules, back clamps, and multiple sets of bolts and nuts. Each sealing module and modular clamp has at least one right angle in its cross-section and has through holes. The back clamp also has multiple through holes evenly distributed, and the distribution of through holes on the back clamp is the same as the distribution of through holes after seamless splicing of the sealing modules.

[0007] The right-angled sides of multiple plugging modules with different shapes abut against each other, and after seamless splicing, they are accommodated in the through-cabin hole frame, capable of covering the electrical through-cabin hole. The modular splint and the back splint are respectively located on both sides of the plugging module and the through-cabin hole frame. The plugging module is tightened by bolts and nuts passing through the modular splint, the plugging module, the through-cabin hole frame and the back splint to achieve the plugging of the electrical through-cabin hole.

[0008] Furthermore, the plugging module includes a first plugging module with a rectangular cross-section, a second plugging module with a "convex" cross-section, a third plugging module with a square cross-section, a fourth plugging module with a square cross-section having a rounded corner, a fifth plugging module with a "cross" cross-section, a sixth plugging module with a right-angled sector cross-section, and a seventh plugging module with a right-angled isosceles triangle cross-section.

[0009] Furthermore, the fourth plugging module has multiple replacement parts with different rounded corner sizes.

[0010] Furthermore, the number of through holes on the second plugging module is 4, the number of through holes on the first plugging module is 2 - 3, and the number of through holes on the fifth plugging module is 5; the number of through holes on the third plugging module, the fourth plugging module, the sixth plugging module, and the seventh plugging module is 1.

[0011] Furthermore, the width of the lateral extension part of the second plugging module and the fifth plugging module is 1 / 2 of the width of the longitudinal extension part.

[0012] Furthermore, the material of the plugging module is nitrile rubber.

[0013] Furthermore, there are multiple back splints, and the width of each back splint is not completely the same.

[0014] Furthermore, the length of the back splint is greater than the length of the electrical through-cabin hole.

[0015] Based on the above-mentioned temporary plugging method for the ship electrical through-cabin hole, it includes: according to the shape of the electrical through-cabin hole, splicing several plugging modules with different shapes and sizes in the through-cabin hole frame, making there be no gaps between adjacent plugging modules and between the plugging module and the through-cabin hole frame, and using the modular splint, the back splint, bolts and nuts to tighten the plugging module to achieve the plugging of the electrical through-cabin hole.

[0016] The beneficial effects of the present invention are:

[0017] In this invention, each sealing module and modular clamp has at least one right angle in its cross-section. This facilitates direct splicing of the sealing modules. When multiple sealing modules of different shapes abut each other at their right angles, gaps are avoided, achieving a seamless splicing to ensure the tightness of temporary sealing. Furthermore, the modular clamp, sealing module, and back clamp are connected by bolts and nuts, facilitating disassembly and reassembly, and promoting the reuse of the sealing modules, thus avoiding resource waste due to difficulty in secondary use. Using modular clamps with the same cross-sectional shape as the sealing module also prevents the bolt heads from directly pressing on the sealing module, causing it to sink and affecting its secondary use, and also prevents excessive deformation of the sealing module from affecting the sealing effect.

[0018] In this invention, the first, second, and square third sealing modules can be located in the middle part of the penetration hole frame or on the right-angled side of the penetration hole frame. The fourth and sixth sealing modules can be used for the rounded corner design of the penetration hole frame, the seventh sealing module can be used for the chamfered design of the penetration hole frame, and the fifth sealing module can be located in the middle part. This allows different combinations of sealing modules to be used with different penetration hole frames. Whether it is a right-angled, rounded, or chamfered design, the penetration hole frame can be blocked by splicing. The fourth sealing module has multiple replacement parts with different rounded corner sizes, thus it can be adapted to different sizes of rounded corners. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0024] Figure 1-2 This invention provides a structure for a temporary sealing device for electrical penetration holes in ships. The temporary sealing device includes several sealing modules 1 of different shapes, modular clamping plates 6 with the same cross-sectional shape as the sealing modules 1, a back clamping plate 2, and multiple sets of bolts 3 and nuts 4. Each sealing module 1 and modular clamping plate 6 has at least one right angle in its cross-section and through holes. The back clamping plate 2 also has multiple through holes evenly spaced, and the distribution of the through holes on the back clamping plate 2 is the same as the distribution of the through holes in the sealing modules 1 after seamless splicing. The right-angled sides of the multiple sealing modules 1 of different shapes abut against each other, are seamlessly spliced, and accommodated within the penetration hole frame 5, thus covering the electrical penetration hole. The fact that each sealing module 1 and modular clamping plate 6 have at least one right angle in their cross-section facilitates direct splicing of the sealing modules 1. When the right-angled sides of the multiple sealing modules 1 of different shapes abut against each other, gaps are avoided, achieving a seamless splicing. Modular clamping plate 6 and back clamping plate 2 are located on both sides of the sealing module 1 and the through-hole frame 5, respectively. The sealing module 1 is pressed together by bolts 3 and nuts 4 that pass through the modular clamping plate 6, the sealing module 1, the through-hole frame 5, and the back clamping plate 2 to seal the electrical through-hole. The modular clamping plate 6, the sealing module 1, the through-hole frame 5, and the back clamping plate 2 are detachably connected by bolts 3 and nuts 4, which is convenient for disassembly and assembly, facilitates the reuse of the sealing module, and avoids resource waste caused by the inability to reuse it.

[0025] Combination Figure 3As shown, the plugging module 1 includes a first plugging module 11 with a rectangular cross-section, a second plugging module 12 with a "convex" cross-section, a third plugging module 13 with a square cross-section, a fourth plugging module 14 with a square cross-section having a rounded corner, a fifth plugging module 15 with a "cross" cross-section, a sixth plugging module 6 with a right-angled sector cross-section, and a seventh plugging module 17 with a right-angled isosceles triangle cross-section. Among them, the first plugging module 11, the second plugging module 12, and the square third plugging module 13 can be located in the middle part of the penetration hole frame 5 or on the right-angled sides of the penetration hole frame 5. The fourth plugging module 14 and the sixth plugging module 6 can be used for the rounded corner design of the penetration hole frame 5. The seventh plugging module 17 can be used for the chamfer design of the penetration hole frame 5. The fifth plugging module 15 can be located in the middle part, so that different combinations of the plugging modules 1 can use different penetration hole frames 5. Whether it is a right angle, a rounded corner or a chamfer design, the penetration hole frame 5 can be blocked by splicing. The fourth plugging module 14 has multiple replacement parts with different rounded corner sizes, so it can be applied to different-sized rounded corners. At the same time, the modular splint 6 with the same cross-sectional shape as the plugging module 1 also includes a first modular splint 11 in the shape of a rectangle, a second modular splint 12 in the shape of a "convex", a third modular splint 13 in the shape of a square, a fourth modular splint 14 in the shape of a square with a rounded corner, a fifth modular splint 15 in the shape of a "cross", a sixth modular splint 6 in the shape of a right-angled sector, and a seventh modular splint 17 in the shape of a right-angled isosceles triangle. The material of the plugging module 1 is nitrile rubber, which has excellent elasticity and sealing performance, ensuring the tightness of the temporary plugging and meeting the requirements of the water pressure and airtightness tests. Since the plugging module 1 is rubber, a modular splint 6 with the same cross-sectional shape as the plugging module 1 is provided. When using bolts 3 and nuts 4 to connect the modular splint 6, the plugging module 1, the penetration hole frame 5, and the back splint 2, it can also avoid the direct extrusion of the bolt 3 head on the plugging module 1, which causes the plugging module 1 to sink. On the one hand, it affects the secondary use of the plugging module 1, and on the other hand, it is also easy to affect the sealing effect due to excessive deformation of the plugging module 1. The width of the lateral extension part of the second plugging module 12 and the fifth plugging module 15 is 1 / 2 of the width of the longitudinal extension part to achieve various size combinations.

[0026] Through holes of the same size are provided at corresponding positions between the plugging module 1 and the back splint 2, and the two are detachably connected by bolts 3 and nuts 4. Specifically, the bolt 3 passes through the through holes on the plugging module 1 and the back splint 2 in sequence and is threadedly connected to the nut 4. The through holes on each plugging module 1 are of the same size, and bolts 3 and nuts 4 of the same model can be used to connect the plugging module 1 and the back splint 2. The same specification tools can also be used during disassembly and assembly. A plurality of back splints 2 are provided. The width of each back splint 2 is not completely the same and corresponds to the height of a different plugging module 1. The back splint 2 matches the plugging module 1 and is modularly designed, facilitating processing, production and management. The length of the back splint 2 is not less than the length of the cabin penetration frame 5. The number of through holes on the second plugging module 12 is 4, the number of through holes on the first plugging module 11 is 2 - 3, and the number of through holes on the fifth plugging module 15 is 5; the number of through holes on the third plugging module 13, the fourth plugging module 14, the sixth plugging module 16 and the seventh plugging module 17 is 1; the number of through holes on the modular splint 6 is the same as the number of through holes on the corresponding second plugging module 12. The second plugging module 12 can be regarded as integrally formed by arranging 4 square plugging modules in a "convex" shape. The first plugging module 11 can be regarded as integrally formed by 2 - 3 square plugging modules. The fifth plugging module 15 can be regarded as integrally formed by 5 square plugging modules in a cross shape. That is to say, the number of through holes on the plugging modules 1 of various shapes is set according to the same rule. In this way, the positions of the through holes on the back splint 2 can also adopt the same rule, that is, the modularization of the back splint 2 is realized, which is convenient for the design, production and use of the back splint 2.

[0027] The temporary plugging method using the temporary plugging device for ship electrical cabin penetrations of the present invention includes: according to the shape of the electrical cabin penetration, splicing a number of plugging modules 1 with different shapes and sizes within the cabin penetration frame 5, making there be no gaps between adjacent plugging modules 1, between the plugging module 1 and the cabin penetration frame 5, and using the modular splint 6, the back splint 2, bolts 3 and nuts to press the plugging module 1 tightly to achieve the plugging of the electrical cabin penetration.

[0028] In this invention, each sealing module 1 has at least one right angle in its cross-section and modular clamping plate 6. This facilitates direct splicing of the sealing modules 1. When multiple sealing modules 1 of different shapes abut each other, gaps can be avoided to achieve seamless splicing and meet the requirements for ensuring the tightness of temporary sealing. At the same time, the sealing module 1 has excellent elasticity and sealing performance, ensuring the tightness of temporary sealing and meeting the requirements of pressurized water and pressurized air tightness tests. The first sealing module 11, the second sealing module 12, and the square third sealing module 13 can be located in the middle part of the perforation frame 5 or on the right angle side of the perforation frame 5. The fourth sealing module 14 and the sixth sealing module 6 can be used for the rounded corner design of the perforation frame 5. The seventh sealing module 17 can be used for the chamfered design of the perforation frame 5. The fifth sealing module 15 can be located in the middle part. This allows different combinations of sealing modules 1 to use different perforation frames 5. Whether it is a right angle, rounded corner, or chamfered design, the perforation frame 5 can be blocked by splicing. The fourth sealing module 14 has multiple replacement parts with different corner radius sizes, making it suitable for corner radii of different sizes. The modular clamping plate 6, the sealing module 1, and the back clamping plate 2 are connected by bolts 3 and nuts 4, facilitating disassembly and reassembly and enabling the reusability of the sealing module 1. Using a modular clamping plate 6 with the same cross-sectional shape as the sealing module 1 also prevents the bolt heads from directly pressing against the sealing module 1, causing it to sink and affecting its secondary use, and also avoids excessive deformation of the sealing module 1 that could compromise the sealing effect.

[0029] The examples described are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essence of the present invention are within the protection scope of the present invention.
