Description

Technical Field

[0001] This utility model is a sealing and reinforcement structure for ship pipeline penetration components, belonging to the field of sealing and reinforcement technology for penetration components. Background Technology

[0002] Ship interiors are typically divided into multiple compartments, and relevant technical specifications require certain compartments to meet requirements for watertightness, airtightness, and fire resistance. This increases the difficulty of installing pipelines that pass through these compartments. To meet the requirements for pipelines passing through watertight, airtight, and fire-resistant bulkheads and decks, steel penetrations with appropriate fire resistance ratings must be installed at the bulkheads and decks.

[0003] Chinese patent CN215522279U proposes a ship compartment penetration device. Although it uses a compression flange to tightly press the extrusion expansion seal to seal the connection, the compression effect on the outer wall of the pipe is not good, and leakage is prone to occur. Moreover, the pipe is only softly connected to the compartment wall through the extrusion expansion seal, which is prone to shaking and loosening. There is still room for further improvement in its connection sealing performance. There is an urgent need for a sealing and reinforcement structure for ship pipeline penetration devices to solve the above-mentioned problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sealing and reinforcement structure for ship pipeline penetration components, so as to solve the problems mentioned in the background technology. This utility model has a reasonable structure, is easy to repeatedly disassemble and assemble, has good sealing performance at the connection, is simple and convenient to use, and is highly practical.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing and reinforcement structure for shipboard pipelines penetrating a cabin, comprising a bulkhead, a forward fixed seat, a sealing sleeve, a clamping plate, a mounting seat, an adjusting seat, a first pressing seat, a rear fixed seat, and a pipeline. The front fixed seat is provided on the front end face of the bulkhead, a sealing sleeve is provided in front of the forward fixed seat, a clamping plate is provided in front of the forward fixed seat, a mounting seat is welded to the front end face of the clamping plate, an adjusting seat is rotatably provided on the inner side of the mounting seat, a first pressing seat is provided on the inner side of the adjusting seat, a rear fixed seat is provided on the rear end face of the bulkhead, and a pipeline is penetrating through the interior of the bulkhead.

[0006] Furthermore, the surface of the bulkhead is provided with a groove, the front end face of the front fixed seat is provided with a countersunk hole, a long bolt is provided inside the countersunk hole, a gasket is provided on the rear end face of the rear fixed seat, a nut is provided on the rear end face of the gasket, the long bolt passes through the bulkhead, the rear fixed seat and the gasket in sequence and then engages with the nut, and a sealing ring is provided on the rear end face of the front fixed seat.

[0007] Furthermore, the front fixed seat is provided with a threaded seat on its front end face, and a short bolt is provided in front of the clamping plate. The short bolt passes through the clamping plate and engages with the threaded seat. The front fixed seat is provided with a compression seat on its front end face. The compression seat cooperates with the clamping plate to compress and fix the rear end of the sealing sleeve.

[0008] Furthermore, the inner side of the mounting base is provided with a first thread, and the outer side of the adjusting base is provided with a second thread. The adjusting base is engaged with the mounting base through the first thread and the second thread, and the front end face of the adjusting base is provided with a groove.

[0009] Furthermore, the rear end face of the adjusting seat is provided with a rotating cavity, and the front end face of the first pressing seat is provided with a rotating connecting block. The first pressing seat is rotatably connected to the adjusting seat through the rotating connecting block and the rotating cavity.

[0010] Furthermore, a second clamping seat is welded to the outer side of the pipe. The first clamping seat and the second clamping seat cooperate to compress and fix the front end of the sealing sleeve. A connecting flange is welded to the outer side of the pipe. A connecting bolt is provided on the rear side of the connecting flange. The pipe is fixedly connected to the rear fixing seat through the connecting flange and the connecting bolt.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a sealing and reinforcement structure for ship pipeline penetration components. Because it adds a clamping plate, a compression seat, a first clamping seat, a second clamping seat, and an adjusting seat, during installation, the clamping plate, in conjunction with the compression seat, clamps the rear end of the sealing sleeve, thereby ensuring the seal between the clamping plate and the front fixed seat. Then, the pipe is inserted from the rear fixed seat side, allowing the second clamping seat to enter the sealing sleeve. A special adjusting tool is then inserted into the groove, and the adjusting seat is rotated. Because the first and second threads mesh with each other, rotating the adjusting seat causes it to move inward along the mounting seat, driving the first clamping seat to move as well. Under the combined action of the first and second clamping seats, the front end of the sealing sleeve is pressed and fixed, thus ensuring a sealing effect. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a sealing and reinforcement structure for ship pipelines penetrating the cabin, including a bulkhead 1, a front fixed seat 2, a sealing sleeve 3, a clamping plate 4, a mounting seat 5, an adjusting seat 6, a first pressing seat 7, a rear fixed seat 8, and a pipe 9. The front fixed seat 2 is provided on the front end face of the bulkhead 1, the sealing sleeve 3 is provided in front of the front fixed seat 2, the clamping plate 4 is provided in front of the front fixed seat 2, the mounting seat 5 is welded to the front end face of the clamping plate 4, the adjusting seat 6 is rotatably provided on the inner side of the mounting seat 5, the first pressing seat 7 is provided on the inner side of the adjusting seat 6, the rear fixed seat 8 is provided on the rear end face of the bulkhead 1, and the pipe 9 is penetrating inside the bulkhead 1. This design solves the problem of poor sealing performance of the original sealing and reinforcement structure for penetrating the cabin.

[0021] In the first embodiment of this utility model: a groove 11 is formed on the surface of the bulkhead 1; a countersunk hole 21 is formed on the front end face of the front fixing seat 2, and a long bolt 22 is installed inside the countersunk hole 21; a washer 81 is provided on the rear end face of the rear fixing seat 8, and a nut 82 is provided on the rear end face of the washer 81; the long bolt 22 passes through the bulkhead 1, the rear fixing seat 8, and the washer 81 in sequence and engages with the nut 82; a sealing ring 25 is provided on the rear end face of the front fixing seat 2; and the nut 82 can fix the long bolt 22, thereby fixing the front fixing seat 2 and the rear fixing seat 8 to the two sides of the bulkhead 1 respectively. The sealing ring 25 ensures the sealing performance of the contact area between the front fixed seat 2 and the surface of the bulkhead 1. The front fixed seat 2 is provided with a threaded seat 23 at its front end. A short bolt 41 is provided in front of the clamping plate 4. The short bolt 41 passes through the clamping plate 4 and engages with the threaded seat 23. This design can fix the clamping plate 4 and the front fixed seat 2 in place. The front fixed seat 2 is provided with a compression seat 24 at its front end. The compression seat 24 cooperates with the clamping plate 4 to compress and fix the rear end of the sealing sleeve 3. The design of the compression seat 24 can ensure the sealing performance at the connection between the front fixed seat 2 and the clamping plate 4.

[0022] The inner side of the mounting base 5 has a first thread 51, and the outer side of the adjusting base 6 has a second thread 61. The adjusting base 6 is engaged with the mounting base 5 through the first thread 51 and the second thread 61. The front end face of the adjusting base 6 has a groove 62, which facilitates the user's rotation of the adjusting base 6 using a special tool. The design of the first thread 51 and the second thread 61 facilitates the movement of the adjusting base 6. The rear end face of the adjusting base 6 has a rotating cavity 63. The front end face of the first clamping base 7 is provided with a rotating connecting block 71. The first clamping base 7 is connected to the mounting base 5 through the rotating connecting block 71 and the rotating cavity 63. The moving cavity 63 is rotatably connected to the adjusting seat 6. This design allows the first pressing seat 7 to rotate independently of the adjusting seat 6. A second pressing seat 91 is welded to the outer side of the pipe 9. The first pressing seat 7 and the second pressing seat 91 cooperate to compress and fix the front end of the sealing sleeve 3. This design can ensure the sealing performance of the outer wall of the pipe 9. A connecting flange 92 is welded to the outer side of the pipe 9. A connecting bolt 93 is provided on the rear side of the connecting flange 92. The pipe 9 is fixedly connected to the rear fixed seat 8 through the connecting flange 92 and the connecting bolt 93. This design facilitates fixing the position of the pipe 9.

[0023] As a second embodiment of this utility model: the user first fixes the front fixed seat 2 and the rear fixed seat 8 to the two sides of the bulkhead 1 respectively using long bolts 22 and nuts 82. Then, the clamping plate 4 is fixedly installed to the front fixed seat 2 using short bolts 41. During installation, the clamping plate 4 cooperates with the compression seat 24 to clamp the rear end of the sealing sleeve 3, thereby ensuring the sealing between the clamping plate 4 and the front fixed seat 2. Then, the pipe 9 is inserted from the side of the rear fixed seat 8, so that the second compression seat 91 enters the interior of the sealing sleeve 3. Then, the pipe 9 is fixedly connected to the rear fixed seat 8 using connecting bolts 93 and connecting flanges 92, thereby preventing the pipe 9 from loosening. Then, a special adjusting tool is inserted into the groove 62 and the adjusting seat 6 is rotated. Since the first thread 51 and the second thread 61 are meshed with each other, rotating the adjusting seat 6 causes it to move inward along the mounting seat 5, and drives the first compression seat 7 to move together. Under the combined action of the first compression seat 7 and the second compression seat 91, the front end of the sealing sleeve 3 is pressed and fixed, thereby ensuring the sealing effect.
