A novel cable sealing structure

Abstract

This utility model discloses a novel cable sealing structure, comprising: a three-sided rectangular cable frame and two web plates. The three-sided rectangular cable frame includes a long-side rectangular steel plate and two short-side rectangular steel plates. The two short-side rectangular steel plates are vertically fixed to both sides of the long-side rectangular steel plate and aligned. The structure of the three-sided rectangular cable frame is "U". The web plates are fixed to the ends of the short-side rectangular steel plates, ensuring that the edges of the web plates do not protrude beyond the outer edge of the three-sided rectangular cable frame. The structure of the web plates is "D". The open cable structure allows the cable frame to be installed closer to the wall, making it particularly suitable for space-constrained applications. It can be installed through the deck, and the addition of web plates at the cable-wall welding point provides a larger operating space for the welder. The "U"-shaped structure allows welders to directly contact and weld the weld between the short-side rectangular steel plates and the wall from the outside, thereby ensuring stable and reliable welding quality, reducing rework rates, and improving overall construction quality.

Description

Technical Field

[0001] This utility model belongs to the field of marine engineering technology, and specifically relates to a novel cable sealing structure. Background Technology

[0002] In the field of marine engineering, especially in the construction of offshore oil and gas platforms, the laying and protection of cables is a crucial aspect. These cables are responsible for providing power and control signals to the electrical and instrumentation equipment throughout the platform, and therefore, the way they pass through decks and walls directly affects the platform's safety and functionality. Traditionally, rectangular cable frames are used for fixing and protecting cables to allow them to pass through different decks or walls. However, in practical applications, this traditional solution faces many challenges.

[0003] Firstly, when cable frames are located beside deck walkways (safe passageways) or inside rooms, they must be installed as close to the wall panels as possible to ensure sufficient passage width or facilitate the installation of internal outfitting panels. However, due to the limited space between the cable frame and the wall panels, and the relatively high wall panels (typically 250mm high, with the portion extending 150mm above the deck), effective welding of the cable frame to the deck on the wall side is difficult. Even attempts to overcome this difficulty using methods such as longer welding rods result in inconsistent welding quality due to limited operating space and poor visibility, leading to issues such as porosity, slag inclusions, weld beads, and substandard weld positions. These problems not only increase the risk of rework but also significantly impact work efficiency and extend project cycles.

[0004] Secondly, existing cable frame designs place high demands on the pre-arrangement of cable positions, especially when using MCT frames. The cable layout within each frame requires meticulous planning in advance, which undoubtedly increases the time cost and technical complexity of the design phase. Furthermore, for applications in special environments, such as those requiring fire resistance, selecting appropriate sealing materials is a pressing issue. Conventional cable frame designs often limit the use of only a single type of sealing material, restricting their applicability and flexibility. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of cable sealing structure, which simplifies the installation process by providing a three-sided structure that is neither fully enclosed nor sealed, and can be directly attached to the wall, thus providing a more efficient, flexible and easy-to-implement cable frame solution.

[0006] To solve the above problems, the technical solution adopted by the present utility model is as follows: A new type of cable sealing structure, comprising: a three-sided rectangular cable frame, the three-sided rectangular cable frame includes a long-side rectangular steel plate and two short-side rectangular steel plates, the two short-side rectangular steel plates are perpendicularly fixed on both sides of the long-side rectangular steel plate, and the two short-side rectangular steel plates are aligned, and the structure of the three-sided rectangular cable frame is in a "C" shape;

[0007] Two webs, the webs are fixed at the ends of the short-side rectangular steel plates and the edges of the webs do not protrude beyond the outer edge of the three-sided rectangular cable frame, and the structure of the webs is in a "D" shape.

The cable frame formed by this structure is not enclosed and is hollow. The open cable structure enables the cable frame to be installed closer to the wall, especially suitable for occasions with limited space, and can penetrate the deck. Moreover, a web is added at the welding joint between the cable and the wall, providing a large operating space for welders. The "C" shape structure allows welders to directly access and weld the weld between the short-side rectangular steel plate and the wall from the outside, thus ensuring stable and reliable welding quality, reducing the rework rate, and improving the overall construction quality.

[0009] For the above-mentioned sealing structure, the size of the long-side rectangular steel plate is 400 mm in length and 250 mm in thickness.

[0010] For the above-mentioned sealing structure, the size of the short-side rectangular steel plate is 250 mm in length and 250 mm in thickness.

[0011] For the above-mentioned sealing structure, the size of the web is 280 mm in diameter and 15 mm in width.

[0012] For the above-mentioned sealing structure, a cavity is provided inside the three-sided rectangular cable frame formed by the long-side rectangular steel plate and the short-side rectangular steel plates, and the "C" shape notch side is installed facing the wall, and the deck can penetrate the cavity.

[0013] For the above-mentioned sealing structure, the "C" shape notch side can be directly fixed to the wall, and there are inner and outer welds between the short-side rectangular steel plate and the wall.

[0014] For the above-mentioned sealing structure, the short-side rectangular steel plate and the long-side rectangular steel plate are fixed by welding.

[0015] For the above-mentioned sealing structure, the short-side rectangular steel plate and the web are fixed by welding.

[0020] Explanation of the reference numerals in the drawings: 100 three-sided rectangular cable frame, 110 long-side rectangular steel plate, 120 short-side rectangular steel plates, 130 cavity, 140 internal weld, 150 external weld, 200 web, 300 deck, 400 wall, 500 safety passage border, 600 cable. Detailed Description of the Embodiment

[0021] The following details the embodiments of the present utility model. Referring to Figures 1 to 2 , the embodiments of the present utility model provide a new type of cable sealing structure, including: a three-sided rectangular cable frame 100 and two webs 200. The three-sided rectangular cable frame 100 includes a long-side rectangular steel plate 110 and two short-side rectangular steel plates 120. The two short-side rectangular steel plates 120 are perpendicularly fixed on both sides of the long-side rectangular steel plate 110 and are aligned. The structure of the three-sided rectangular cable frame 100 is in a "C" shape; the web 200 is fixed at the end of the short-side rectangular steel plate 120 and the edge of the web 200 does not protrude beyond the outer edge of the three-sided rectangular cable frame 100. The structure of the web 200 is in a "D" shape. The three-sided rectangular cable frame 100 proposed by the present utility model is composed of a long-side rectangular steel plate 110 and two short-side rectangular steel plates 120, and its shape is in a "C" shape. The cable frame formed by this structure does not enclose and is hollow. The open cable structure enables the cable frame to be installed closer to the wall 400, especially suitable for occasions with limited space, and can penetrate the deck 300. Moreover, a web 200 is added at the welding joint between the cable 600 and the wall 400, providing a large operating space for welders. The "C" shape structure allows welders to directly access and weld the weld between the short-side rectangular steel plate 120 and the wall from the outside, thus ensuring stable and reliable welding quality, reducing the rework rate, and improving the overall construction quality.

[0022] Furthermore, traditional cable frames are mostly rectangular with four sides. When a rectangular cable frame passes through the deck 300 and is installed close to the wall panel, the gap between the cable frame and the wall panel is too small, and the cable frame wall panel is relatively high (generally 250mm, 150mm above the deck 300). This results in the wall panel of the cable frame being unable to be welded to the deck 300. Even using methods such as using longer welding rods, it is not only labor-intensive and time-consuming, but even if a weld is completed, the resulting weld will have quality problems such as porosity, slag inclusions, weld beads, and unqualified weld positions, resulting in rework. This affects the subsequent work and reduces efficiency. This utility model proposes a novel cable sealing structure with a simple design, referring to... Figure 1 and Figure 2 The cable frame material is easy to select, and the manufacturing site can be self-made. Compared with the conventional rectangular cable frame, it has one less side, saving project construction costs. Compared with the multi-cable crossing device frame (MCT frame), it is not necessary to pre-arrange the cable 600 positions in each cable frame, saving design costs. Furthermore, this application does not limit the specific dimensions of the long-side rectangular steel plate 110, the short-side rectangular steel plate 120, and the web plate 200. Preferably, the dimensions of the long-side rectangular steel plate 110 are 400mm in length and 250mm in thickness. This dimension also takes into account the matching relationship with building components (such as deck 300, wall panels). For example, in offshore platforms, the 300mm deck spacing and wall structure typically have certain standards. A 400mm span allows for smooth passage without damaging the original structure, while ensuring airtightness and fire resistance. The short-side rectangular steel plate 120 has dimensions of 250mm in length and 250mm in thickness. The short-side rectangle ensures that the connection area between the cable frame and the wall is large enough to withstand the load from the cable and the environment, while not occupying too much space and affecting the passage or layout of the surrounding area. Moreover, the thickness is consistent with the thickness of the long-side rectangle, ensuring the uniform height of the entire cable frame, which facilitates welding operations in different directions. Especially in welding near the wall, the uniform height also helps welders to weld accurately and improves weld quality. The web plate 200 has dimensions of 280mm in diameter and 15mm in width. In terms of structural stability, the 280mm diameter ensures that the web plate 200 can provide sufficient support area, effectively distributing the stress generated during welding and preventing the cable frame from deforming or twisting during use. Especially in harsh environments such as marine engineering, facing external loads such as strong winds and wave impacts, an appropriate web 200 dimension can significantly improve the overall structural rigidity and bending resistance, ensuring the safe operation of the cable 600. From a manufacturing perspective, a width of 15mm ensures that the web 200 has sufficient strength to bear the expected load without increasing material costs or affecting installation operations due to excessive width. Simultaneously, this width is suitable for cutting and shaping with most standard processing equipment, improving production efficiency and reducing manufacturing costs.

[0023] Furthermore, the three-sided rectangular cable frame 100, formed by the long rectangular steel plate 110 and the short rectangular steel plate 120, has a cavity 130. The cable is installed with the "U"-shaped notch side facing the wall 400, and the deck 300 can pass through the cavity 130. The cavity 130 provides ample space for the cable 600, allowing it to be arranged freely without being compressed. This not only facilitates heat dissipation for the cable 600 but also makes subsequent maintenance easier. Compared to traditional closed cable frames, the open design reduces restrictions on cable routing direction and increases flexibility. The "U"-shaped notch side facing the wall 400 directly simplifies the installation process. Traditional cable frames, being enclosed on all sides, make high-quality welding difficult on the side near the wall 400, easily leading to welding defects. This invention, by having the notch side facing the wall 400, allows welders to operate directly from the outside, ensuring welding quality and aesthetics, reducing rework rates, and improving work efficiency. Of course, the "U"-shaped notch side can be directly fixed to the wall 400, and the short rectangular steel plate 120 has an inner weld 140 and an outer weld 150 between it and the wall 400. Direct fixing to the wall 400 greatly simplifies the installation process, eliminating the need for complex positioning and adjustment, and allowing for rapid initial fixing of the cable frame. This method is particularly suitable for scenarios with limited space or requiring rapid deployment, such as emergency repairs or temporary facility construction on offshore platforms. The design of the inner and outer welds significantly improves the strength and reliability of the welded joint. The inner weld 140 primarily strengthens the initial connection between the cable frame and the wall 400, ensuring the initial stability of the structure; while the outer weld 150 further reinforces the connection point, forming a double protection mechanism. Even if a problem occurs in one layer of the weld, the other layer can still maintain basic functionality, preventing the overall structure from collapsing due to a single point of failure.

[0024] Furthermore, this utility model does not limit the specific fixing method of the short-side rectangular steel plate 120 and the long-side rectangular steel plate 110. Preferably, the short-side rectangular steel plate 120 and the long-side rectangular steel plate 110 are fixed by welding; the short-side rectangular steel plate 120 and the web plate 200 are also fixed by welding. The welding connection ensures a high-strength bond between the short-side rectangular steel plate 120 and the long-side rectangular steel plate 110. Compared to other connection methods (such as bolted connections), welding can form a continuous and uninterrupted joint surface, significantly enhancing the integrity and load-bearing capacity of the structure. This is particularly important for cable frames that bear large mechanical loads, especially on offshore platforms where they frequently face extreme environmental conditions such as strong winds and waves. Reliable welding connections can effectively ensure the safe and stable operation of the cable frame. At the same time, the welding connection gives the short-side rectangular steel plate 120 and the D-shaped web plate 200 extremely high connection strength. When facing complex external forces (such as earthquakes and wave impacts), the welded joint can provide stable support, ensuring the integrity and stability of the cable frame structure. Especially for components like the D-shaped web 200 that need to withstand additional lateral loads, the welded connection method can maximize its reinforcing effect and effectively prevent deformation or damage to the cable frame. Of course, this application does not limit the specific structure of the triangular rectangular cable frame 100. Preferably, the structure of the triangular rectangular cable frame 100 can also be semi-circular or semi-elliptical. Different shapes of cable frames have their own advantages in structural strength. Semi-circular or semi-elliptical designs generally have better compressive and bending resistance because the circular cross-section can more evenly distribute applied stress, reduce stress concentration areas, and thus reduce the risk of structural damage. Especially when facing strong vibration or impact loads, this shape can better demonstrate its superior mechanical properties, ensuring the safe operation of the cable 600. Furthermore, this application does not limit the specific material of the triangular rectangular cable frame 100. Preferably, the triangular rectangular cable frame 100 is made of high-strength metal material.
