Abstract
Description
Technical Field
[0001] This application relates to the field of high-energy pipeline protection devices, and in particular to a high-energy pipeline anti-slip component. Background Technology
[0002] Generally, high-energy pipelines are a type of high-tech pipeline used in the energy field, typically for transporting high-energy, high-velocity substances. These substances may be gases, liquids, or plasmas, and they are usually transported through the pipeline at extremely high speeds and energy states. The extremely high velocity of the substances in high-energy pipelines gives them high transport efficiency. To maintain the high-velocity flow of substances within the pipeline, high-energy pipelines typically maintain high pressure. If a pipeline ruptures, the fluid ejects at high speed from the breach, generating enormous impact energy that can powerfully impact surrounding structures and equipment, even affecting the safe operation of power equipment, causing further damage, and threatening the safety of equipment and personnel.
[0003] In existing technologies, high-energy pipelines are typically protected using anti-slip devices, and there are various types of such devices available on the market. Among these, the method of adding numerous U-shaped clamps and other anti-slip devices to protect surrounding safety components from breakage and impact accidents often relies on screw-type steel. The tensile strength of these U-shaped clamps is insufficient to prevent the high-energy pipeline from breaking, potentially causing secondary accidents. Utility Model Content
[0004] This specification provides an embodiment of a high-energy pipeline anti-slip component, which partially solves the problems existing in the prior art.
[0005] The embodiments in this specification adopt the following technical solutions:
[0006] This specification provides a high-energy pipeline anti-throw component, including:
[0007] The steel cable U-shaped anti-slinging component is a U-shaped steel cable with a spiral strand cross-section, formed by rotating and crossing multiple steel wires at a preset angle. It is used to limit the impact range of high-energy pipelines.
[0008] A buffer energy-absorbing layer is set on the periphery of the cable-stayed U-shaped anti-swing component to absorb the high-energy pipeline impact energy and buffer the impact on the cable-stayed U-shaped anti-swing component.
[0009] A sealing layer, located around the buffer energy-absorbing layer, is used to create a sealed protective layer for the buffer energy-absorbing layer.
[0010] Optionally, the buffer energy-absorbing layer includes:
[0011] A buffer is installed around the cable-stayed U-shaped anti-swing component to reduce the impact energy of high-energy pipes hitting the cable-stayed U-shaped anti-swing component.
[0012] Energy-absorbing components are installed around the buffer components to absorb the energy ejected from the high-energy pipeline.
[0013] Optionally, the sealing layer is configured as a two-ring structure with an energy-absorbing element sandwiched between the two ring structures.
[0014] Optionally, multiple high-energy pipeline anti-spinning components are installed on the bend section of the high-energy pipeline, and each high-energy pipeline anti-spinning component on the bend section is fixedly connected to the attachment surface of the high-energy pipeline.
[0015] Optionally, multiple high-energy pipeline anti-spinning components are installed on the near-bend side of the straight section of the high-energy pipeline, and each high-energy pipeline anti-spinning component on the straight section is hinged to the attachment surface of the high-energy pipeline.
[0016] The above-described at least one technical solution adopted in the embodiments of this specification can achieve the following beneficial effects:
[0017] By rotating and crossing multiple steel wires at a preset angle to form a U-shaped steel cable with a spiral cross-section, a steel cable-type U-shaped anti-swing component with high tensile strength and rigidity is obtained. A buffer energy-absorbing layer is set on the outside of the steel cable-type U-shaped anti-swing component. When the high-energy pipeline anti-swing component is impacted by a high-energy pipeline, the buffer energy-absorbing layer first absorbs the impact energy of the high-energy pipeline, avoiding direct impact on the steel cable-type U-shaped anti-swing component, reducing the impact intensity on the steel cable-type U-shaped anti-swing component, improving the overall tensile strength of the high-energy pipeline anti-swing component, and thus improving the protection effect on the high-energy pipeline.

[0024] To make the objectives, technical solutions, and advantages of this specification clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without creative effort are within the scope of protection of this application.
[0025] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.
[0026] Generally, when preventing high-energy pipelines from being thrown, U-shaped clamps are often installed on the straight sections of the pipeline. However, when the rigidity of the high-energy pipeline is insufficient, the bends may be the first to undergo shear deformation and break. Furthermore, high-energy pipelines are arranged in complex and tortuous patterns in special environments such as nuclear power plants. Therefore, an optimized arrangement of anti-throw components plays a crucial role in the normal operation of the pipeline.
[0027] Figure 1 This is a cross-sectional schematic diagram of a high-energy pipeline anti-throw component described in this specification. Figure 1 It can be seen that the high-energy pipeline anti-swing component includes a buffer energy-absorbing layer and a sealing layer formed by a steel cable U-shaped anti-swing component 4, a buffer component 3 and an energy-absorbing component 2. Figure 2 This is a front view of a high-energy pipeline anti-throw component described in this specification. Figure 2 It can be seen that it includes a buffer and energy-absorbing layer and a sealing layer 1 formed by a steel cable U-shaped anti-swing component 4, a buffer component 3 and an energy-absorbing component 2. Figure 2 The bottom of the structure is a hinged support 5, and the high-energy pipeline anti-slip component can be hinged based on the hinged support 5. Of course, Figure 2 The example shown is for illustrative purposes only; the high-energy pipeline anti-slip component can also be fixedly connected to the support surface.
[0028] Among them, the cable-type U-shaped anti-slinging component 4 is used to limit the impact range of high-energy pipelines. The cable-type anti-slinging component 4 can be made of stainless steel, and the entire cable can be woven from multiple steel wires. After the multiple steel wires are rotated and crossed at a specific angle to form the cable, a spiral strand steel wire rope is formed. The cable can often form a uniform structure, giving it high tensile strength and rigidity to improve stability. Compared with existing technologies, the high-energy pipeline anti-slinging component based on the cable is lighter and easier to manufacture and apply.
[0029] A buffer energy-absorbing layer can be installed around the aforementioned cable-stayed U-shaped anti-swing component, completely surrounding it. Finally, a sealing layer 1 is attached to the outside of the buffer energy-absorbing layer to seal and protect it. This buffer energy-absorbing layer, when the high-energy pipeline anti-swing component is impacted by a high-energy pipeline, absorbs the impact energy before the cable-stayed U-shaped anti-swing component, thus buffering the impact. This avoids direct contact between the cable-stayed U-shaped anti-swing component and the high-energy pipeline, reducing the impact intensity on the cable-stayed U-shaped anti-swing component and improving its overall protective effect.
[0030] Specifically, in one or more embodiments of this specification, the buffer energy-absorbing layer may include: a buffer element 3 and an energy-absorbing element 4.
[0031] The buffer 3 is installed around the cable-stayed U-shaped anti-swing component to reduce the high-energy pipe impact energy hitting the cable-stayed U-shaped anti-swing component. The buffer 3 can be made of spring steel.
[0032] Energy-absorbing component 4 is installed around the buffer to initially absorb the impact energy from the high-energy pipeline. The energy-absorbing component can be made of aluminum foam or rubber. Taking aluminum foam as an example, energy-absorbing component 4 uses aluminum foam with good cushioning effect, low density, high energy absorption efficiency, and fire and water resistance. While possessing excellent explosion-proof and bulletproof performance, it maintains a relatively light structural weight. As the first protective layer to come into contact with the high-energy pipeline, it can effectively absorb the impact energy from the high-energy pipeline, protecting personnel and property safety.
[0033] For the sealing layer 1, in one or more embodiments of this specification, the sealing layer 1 may be configured as a two-ring structure with an energy-absorbing element 4 sandwiched between the two ring structures.
[0034] Furthermore, in one or more embodiments of this specification, when applying high-energy pipeline anti-throw components, the protective effect can be improved through various arrangement methods. Traditional anti-throw component arrangement methods often only involve arranging them perpendicular to the cross-section of the high-energy pipeline, which has certain limitations. This utility model selects different arrangement methods for different working conditions. By combining nonlinear calculation software such as LS-DYNA to calculate and analyze the energy, stress, and impact velocity of the described cases, the most cost-effective basic arrangement method can be determined.
[0035] Figure 3 This is a schematic diagram of one type of layout in this specification. Figure 3The image shows a straight section 3a of a high-energy pipeline, a bend section 3b of a high-energy pipeline, high-energy pipeline anti-slip components 31 on the straight section, and high-energy pipeline anti-slip components 32 on the bend section. Taking a single high-energy pipeline as an example, several high-energy pipeline anti-slip components 31 are arranged along the direction of the high-energy pipeline in the straight section 3a. Based on this, several high-energy pipeline anti-slip components 32 are arranged at a 45° angle in the bend section 3b. The bottom of the high-energy pipeline anti-slip component 31 on the straight section is hinged to the surface of the high-energy pipeline (e.g., a wall), and the bottom of the high-energy pipeline anti-slip component 32 on the bend section is fixedly connected to the surface of the high-energy pipeline.
[0036] Figure 4 This is a schematic diagram of one type II layout method in this specification. Figure 4 The image shows a high-energy pipeline straight section 4a, a high-energy pipeline bend section 4b, a high-energy pipeline straight section near the break point 4c, high-energy pipeline anti-slip components 41, 42, and 43 of the high-energy pipeline straight section near the break point. Taking two straight pipelines on the same plane as an example, several high-energy pipeline anti-slip components 41 are arranged along the direction of the high-energy pipeline in the high-energy pipeline straight section 4a. Based on this, several high-energy pipeline anti-slip components 42 are arranged at a 45° angle in the high-energy pipeline bend section 4b. Based on this, several high-energy pipeline anti-slip components 43 are arranged in the high-energy pipeline straight section near the break point 4c. For the connection method, each high-energy pipeline anti-slip component on the straight section is hinged to the attachment surface of the high-energy pipeline. Each high-energy pipeline anti-slip component on the bend section is fixedly connected to the attachment surface of the high-energy pipeline.
[0037] For multi-pipe systems on the same plane, anti-slip devices can be arranged on the same side of the relative pipe positions. Depending on the needs, protection can often be achieved by increasing the diameter, quantity, and fixed leg length. Since the bottom surface of the anti-slip device needs to leave a space for hinges, after being subjected to impact force, the diameter, quantity, and fixed leg length of the anti-slip device on the side where the tensile direction is the same as the impact force direction can be increased as needed.
[0038] If anti-swing components are arranged on the same plane, space constraints may exist, affecting the layout of pipes and equipment. Furthermore, in some cases, anti-swing components for high-energy pipes may not completely prevent the pipes from swinging, such as when the high-energy pipes are subjected to significant impact or vibration. Therefore, this invention further proposes a multi-pipe system with anti-swing components arranged on different sides relative to the pipe positions.
[0039] Figure 5 This is a schematic diagram of one of the three types of layouts in this specification. Figure 5The image shows the high-energy pipeline bend section 5a near the rupture end, the high-energy pipeline straight section 5b near the rupture end, the high-energy pipeline bend section 5c far from the rupture end, and the high-energy pipeline straight section 5d far from the rupture end. It also shows the high-energy pipeline anti-spinning component 51 for the high-energy pipeline bend section near the rupture end, the high-energy pipeline anti-spinning component 52 for the high-energy pipeline straight section near the rupture end, the high-energy pipeline anti-spinning component 53 for the high-energy pipeline bend section far from the rupture end, and the high-energy pipeline anti-spinning component 54 for the high-energy pipeline straight section far from the rupture end.
[0040] Taking a double-bend pipeline with different planes as an example, assuming the break point is on a different plane from the fixed end of the pipeline, several high-energy pipeline anti-slip components 51 are arranged along a 45° direction in the high-energy pipeline bend section 5a near the break point; several high-energy pipeline anti-slip components 52 are arranged along the pipeline direction in the high-energy pipeline straight section 5b near the break point; several high-energy pipeline anti-slip components 53 are arranged along a 45° direction in the high-energy pipeline bend section 5c far from the break point; and several high-energy pipeline anti-slip components 54 are arranged along the pipeline direction in the high-energy pipeline straight section 5d far from the break point. For the connection method, each high-energy pipeline anti-slip component on the straight section is hinged to the attachment surface of the high-energy pipeline. Each high-energy pipeline anti-slip component on the bend section is fixedly connected to the attachment surface of the high-energy pipeline.
