Description

Technical Field

[0001] This utility model relates to the field of pipeline equipment technology, and in particular to a pipeline fixed support structure and a pipeline transportation system. Background Technology

[0002] Since pipelines in nuclear power plant seawater-related systems are sometimes located below sea level, seawater corrosion is a problem that must be addressed in pipeline transportation systems. Using high-polymer materials with excellent corrosion resistance, such as HDPE (high-density polyethylene), as pipeline materials can effectively solve the corrosion problem of pipelines in nuclear power plant seawater-related systems. Pipeline supports, as an important part of the process system layout, are used to bear the weight of the pipeline, limit pipeline vibration, or control pipeline displacement. Although corrosion-resistant polymer materials solve the problem of pipe corrosion, the harsh marine environment, the strong corrosiveness of seawater, and the extremely high load on underwater pipelines under seismic action place higher demands on the structural performance and stability of the supports.

[0003] Composite material supports offer excellent corrosion resistance, but their strength and stiffness are insufficient, making them unable to withstand the massive hydraulic impacts caused by earthquakes or ocean currents. Cathodic protection technology has high maintenance costs and its effectiveness is unstable in complex environments, making it unsuitable for large-scale applications. Coated anti-corrosion metal supports exhibit good corrosion resistance, but polymer pipes have high toughness and low strength. The point / line contact of traditional supports easily leads to localized stress concentration, causing pipe crushing or cracking. Therefore, it is necessary to provide a fixed support for polymer material pipes suitable for marine applications, with high structural strength, capable of withstanding the massive hydraulic impacts of seawater under earthquakes, and possessing excellent corrosion resistance.

[0035] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0037] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0038] In pipeline transportation systems, traditional metal pipe supports rely on anti-corrosion coatings or cathodic protection technology, which carries the risk of failure in deep-sea environments. While composite material supports are corrosion-resistant, their insufficient strength makes them unable to withstand the hydraulic impact caused by earthquakes or ocean currents. Furthermore, polymer pipes have high toughness but low strength, and the point / line contact of traditional supports can easily lead to localized stress concentration, causing pipe crushing and cracking. Currently, the industry lacks mature support and hanger solutions specifically for underwater polymer pipes, and there is an urgent need to develop fixing structures that combine high structural strength, corrosion resistance, and load distribution capabilities.

[0039] Please see Figures 1 to 5This utility model proposes a pipe fixing support structure, including a base 100 and a support 200. The base 100 is fixed to the civil structure and is used to fix the support structure as a whole to the civil structure. The support 200 is fixed on the base 100 and is used to support and fix the pipe. The pipe section 300 is installed on the support 200. The support 200 consists of an outer frame 210 enclosing the pipe section 300 and a protective plate assembly 220 located inside it. The outer frame 210 is located on the outer periphery of the pipe section 300, enclosing and forming the installation space of the pipe section 300. The protective plate assembly 220 is arranged circumferentially along the pipe section 300 and its inner side is an arc-shaped surface 221 with curvature matching the pipe section 300. It is located circumferentially to limit the pipe section 300 radially. A circumferential fixing ring 310 is integrally formed on the surface of the pipe section 300. The protective plate assembly 220 is located on both sides of the fixing ring 310 and forms a groove structure. The fixing ring 310 is engaged with the groove structure to limit the pipe section 300 axially. A lateral gap is left between the side wall of the groove structure and the fixing ring 310. The non-tightening groove engagement avoids stress concentration and damage to the pipeline. The support 200 uses metal components and is treated with seawater corrosion resistant materials to ensure stable operation in the seawater environment for a long time. By cooperating with the arc-shaped end face of the guard plate assembly 220 and the pipe section 300, the point load is transformed into a surface load, significantly reducing local stress and resulting in high structural strength. At the same time, the groove-type constraint structure formed by the guard plate assemblies 220 on both sides clamps the fixing ring 310, which can resist multi-directional impacts and ensure good stability. Combined with corrosion-resistant material treatment, it can achieve long-term stable operation in deep-sea environments.

[0040] Please see Figures 1 to 5 In one optional embodiment, the base 100 includes an anchor plate 110 and expansion bolts 120. The anchor plate 110 is fixed to the civil structure by the expansion bolts 120. The bracket 200 is welded to the upper surface of the anchor plate 110, providing rigid support through the welded connection. The expansion bolts 120 offset vibration displacement through friction anchoring. The two work together to enhance the seismic load resistance of the bracket 200 and avoid the risk of loosening, making it particularly suitable for seawater erosion environments. In other embodiments, the anchor plate 110 may also use a pre-embedded steel plate or chemical anchors for fixing the structure, or high-strength riveting may be used to adapt to different civil engineering conditions.

[0041] Please see Figures 1 to 5In one optional embodiment, the outer frame 210 includes a rectangular frame 211 and a support frame 212. The rectangular frame 211 serves as an installation frame, with its vertical anchor plate 110 arranged to enclose the installation space of the pipe section 300. The protective plate assembly 220 is disposed within the rectangular frame 211 to fix the pipe section 300. Support frames 212 are provided on both sides of the rectangular frame 211. The support frames 212 serve as lateral reinforcement structures, and are inclined to the anchor plate 110 and the rectangular frame 211. Their two ends are respectively fixed to the anchor plate 110 and the rectangular frame 211. The angle between the support frame 212 and the anchor plate 110 can be, for example, 55°-65°. This triangular support structure decomposes the pipe load into vertical pressure and horizontal shear force, significantly improving the bending stiffness and suppressing the unstable deformation of the frame under hydraulic impact. It is understood that the structure of the outer frame 210 is not limited. In other embodiments, the support frame 212 can also be designed as an X-shaped cross brace or a K-shaped truss structure, and the tilt angle can also be adjusted within a certain range to adapt to different load requirements.

[0042] Please see Figures 1 to 5 In one optional embodiment, the guard plate assembly 220 is evenly distributed and symmetrically arranged on both sides of the fixing ring 310 along the circumference of the pipe segment 300. The multi-point fixing structure ensures the reliability of the fixing and the stability of the overall structure. The impact force is transmitted to the guard plate assembly 220 and converted into multiple force points evenly distributed along the circumference, dispersing the load, avoiding local stress exceeding the limit and crushing, improving the impact resistance, and the symmetrical layout forms a constraint to suppress vibration deflection, resulting in better stability.

[0043] Understandably, to ensure structural strength, the outer frame 210 is made of welded steel frame, and the protective plate assembly 220 is made of steel protective plate 222. The components are connected by welding. At the same time, the support 200 is made of seawater corrosion resistant materials, such as duplex stainless steel, or coated with seawater corrosion resistant paint or titanium-plated on the surface of the steel plate. As a result, the support 200 not only has high structural strength and can withstand the huge impact of seawater, but also has good corrosion resistance, making it suitable for the seabed environment and enabling long-term stable operation.

[0044] Please see Figures 1 to 5 In an optional embodiment, the guard plate assembly 220 includes a guard plate 222 and a guard plate support 223. One end of the guard plate 222 is fixed to the rectangular frame 211, and the other end forms an arc-shaped surface 221 that matches the outer diameter of the pipe section 300. The guard plates 222 are distributed on both sides of the fixing ring 310 to clamp the fixing ring 310. The guard plate support 223 is disposed on the side of the guard plate 222 away from the fixing ring 310. One end of the guard plate support 223 is fixed to the guard plate 222, and the other end is fixed to the rectangular frame 211. It is used to provide radial stiffness support and prevent the guard plate 222 from being deformed under pressure. The guard plate assembly 220 adopts a symmetrical layout so that the load is evenly transmitted to the frame, avoiding stress concentration on one side and ensuring structural strength and stability.

[0045] Please see Figures 1 to 5 In one optional embodiment, one end of the protective plate 222 is welded to the rectangular frame 211, and the other end is an arc-shaped surface 221, which is arranged around the outer periphery of the pipe section 300. The curvature of the arc-shaped surface 221 matches the outer diameter of the pipe section 300 to fit the outer surface of the pipe section 300. Understandably, the pipe section 300, made of polymer materials such as high-density polyethylene, has good toughness but low strength. Under heavy loads, point or line contact with the support structure can cause significant damage, destroying the pipe's structure. The curved surface 221 of the protective plate 222 increases the contact area between the support 200 and the pipe section 300, converting destructive line loads into safe surface loads, improving the fixing effect, enhancing the stability and impact resistance of the support 200, while avoiding damage to the pipe's structure. In coordination with the external rectangular frame 211, the rectangular frame 211 provides full-domain boundary constraints for the protective plate 222, suppressing bending under load. Through a couple resistance mechanism, it enhances overturning resistance, further strengthening the overall structural strength and stability. This allows for long-term stable operation in harsh seawater environments with low maintenance costs.

[0046] Please see Figures 1 to 5 In one optional embodiment, the protective plate support 223 includes multiple support plates evenly distributed along the length of the protective plate 222. These support plates are welded between the protective plate 222 and the rectangular frame 211. The use of multiple support plates forms distributed reinforcing ribs, which decompose and diffuse local impact loads to the entire frame through the support plates, avoiding stress concentration and solving the problem of pressure damage to polymer pipes. At the same time, it significantly improves the bending stiffness of the protective plate 222, avoids instability and deformation, and ensures the residual strength of the structure when a single plate fails, thereby improving the impact resistance stability of the bracket 200.

[0047] Please see Figures 1 to 5 In one optional embodiment, a fixing ring 310 protrudes circumferentially from the outer side of the pipe segment 300. The fixing ring 310 is secured by the protective plates 222 on both sides, thereby fixing the pipe segment 300. The fixing ring 310 secures the pipe, preventing direct contact between the metal parts and the polymer pipe and eliminating the risk of electrochemical corrosion. Utilizing the easy processing and molding characteristics of polymer materials, the fixing ring 310 can be integrally formed on the outer circumference of the pipe segment 300 by injection molding or machining. This ring works in conjunction with the support 200 to fix the pipe segment 300. The integral molding eliminates the risk of connection interface failure and ensures the stability of the pipe segment 300's position.

[0048] Please see Figures 1 to 5In one optional embodiment, a radial gap is left between the arc-shaped surface 221 of the protective plate 222 and the outer wall of the pipe section 300, and a lateral gap is left between the side wall of the protective plate 222 and the fixing ring 310. The gap design allows the pipe to move freely due to thermal expansion and contraction, avoiding the accumulation of thermal stress. Specifically, for example, a radial gap of 2mm-4mm is left between the arc-shaped surface 221 of the protective plate 222 and the outer wall of the pipe section 300, and a lateral gap of 1mm-2mm is left between the side wall of the protective plate 222 and the fixing ring 310. This allows the pipe to deform due to thermal expansion and contraction, avoids structural cracking caused by the accumulation of thermal expansion stress, and controls the displacement amplitude to ensure that the fixing ring 310 and the pipe are constrained by the groove and arc surface in special environments such as earthquakes, thus ensuring the stability of the system. Because the fixing ring 310 is not tightly inserted into the groove structure formed by the protective plate 222, it effectively limits the position while eliminating the local stress concentration of the pipeline caused by the traditional fixing method, preventing the pipeline material from being squeezed and deformed or cracked. Moreover, the gap design allows the pipeline to vibrate slightly within the gap under special environments such as when seismic waves are transmitted, avoiding resonance amplification caused by rigid connection, further reducing the risk of fatigue failure of the pipeline system, and coordinating with the structural design of the diagonal bracing frame to avoid displacement instability of the support structure under external impact.

[0049] Please see Figures 1 to 5 This utility model also proposes a pipeline transportation system, which includes the pipeline fixing support structure described in any of the above embodiments. The pipeline is fixed by the fixing support structure, and it can be applied to seawater pipeline systems in nuclear power plants and other pipeline systems with high structural strength and stability requirements. Specifically, in the seawater pipeline system of a nuclear power plant, the pipeline fixing support structure is fixed to the civil structure by anchor plates 110. The pipeline is made of polymer materials such as HDPE, with a fixing ring 310 integrally formed on it. The pipeline is set inside the support 200. The pipeline is limited and fixed by the structure of the guard plates 222 on both sides of the fixing ring 310 and the arc surface 221 of the guard plate 222. When subjected to force impact, the pipeline load is transmitted to the guard plate assembly 220 through the fixing ring 310, and the arc surface 221 disperses it into a surface load, avoiding damage to the pipeline structure. Combined with the overall structural design of the support 200, the hydraulic impact force can be transmitted to the diagonal bracing frame through the guard plate assembly 220, and finally absorbed by the anchoring system of the base 100, improving the fixing effect, enhancing the stability and impact resistance of the support 200, and the overall structural strength is high. The appropriate gap between the guard plate assembly 220 and the pipeline ensures the free thermal expansion and contraction of the pipeline. At the same time, the support 200 material is treated with corrosion resistance, which can operate stably for a long time in harsh seawater environment and has low maintenance costs.

[0050] In summary, this invention avoids stress concentration and direct contact between the fixing bracket and the polymer pipe through the grooved locking ring design, eliminating the risk of electrochemical corrosion and pipe damage. The matching of the grooved guard plate assembly 220 with the pipe section fixing ring 310, and the matching design of the arc-shaped guard plate 222 with the outer diameter of the pipe section 300, achieves good fixation of the pipe section 300 and solves the problem of pipe damage caused by excessive local linear loads. The diagonal bracing frame and the distributed guard plate support 223 work together to evenly distribute the wave impact load along the guard plate assembly 220 to the impact-resistant frame. Effectively resisting irregular hydraulic loads and improving impact resistance and structural stability, the gap design of the 220 protective plate assembly balances constraint and thermal displacement requirements, allowing the pipeline to expand and contract freely under seawater temperature fluctuations, avoiding thermal stress accumulation and reducing the risk of pipeline system fatigue failure. Thus, it achieves zero pipeline damage and long-term stable operation of supports under harsh sea conditions of strong corrosion, high impact, and variable temperature. Corrosion-resistant material treatment ensures service life in deep-sea environments. The overall structure is simple, strong, and stable, and can adapt to the high load requirements of polymer material pipelines, giving it significant technical advantages in harsh scenarios such as nuclear power plants.
