Description

Technical Field

[0001] This utility model relates to the field of superconducting magnet technology, and in particular to a pipeline structure for a liquid helium-free superconducting magnet coil. Background Technology

[0002] In traditional superconducting magnet technology, to maintain the stable superconducting state of the superconducting coil, it is usually necessary to immerse the superconducting coil in liquid helium. Due to its extremely low boiling point and high thermal conductivity, liquid helium can quickly remove heat from the superconducting coil, ensuring that the coil remains in a superconducting state. To reduce operating costs and improve the stability and safety of the magnet, a tubing structure for a liquid helium-free superconducting magnet coil is needed.

[0003] The piping structure of liquid helium-free superconducting magnet coils achieves effective cooling and stable operation by employing a specific cooling medium and innovative cooling methods. This structure not only eliminates dependence on liquid helium but also improves the system's cooling efficiency and stability, providing new ideas for the development of superconducting magnet technology. However, the refrigerant may experience pressure and temperature fluctuations during flow. If these fluctuations directly affect the piping system, they may cause vibration, wear, or even rupture of the pipes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pipeline structure for a liquid helium-free superconducting magnet coil, which aims to improve the problem that previous pipelines could not effectively absorb the fluctuations generated by the refrigerant during the flow process and could not effectively protect the integrity and stability of the pipeline.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A tubular structure for a liquid helium-free superconducting magnet coil includes a fixed tube. A fixed block is fixedly connected to the inner wall of the fixed tube. A limit rod is fixedly connected to the outer wall of the fixed block. A first spring and a sliding ring are slidably connected to the outer wall of the limit rod. The outer wall of the first spring is fixedly connected to the outer wall of the sliding ring. A first U-shaped block is fixedly connected to the outer wall of the sliding ring. A connecting rod is rotatably connected to the inside of the first U-shaped block. A second U-shaped block is rotatably connected to the outer wall of the connecting rod. A conveying assembly is provided on the outer wall of the second U-shaped block for conveying refrigerant.

[0007] Preferably, the conveying assembly includes an insulated pipe, the outer wall of which is fixedly connected to the outer wall of the second U-shaped block, and a conveying pipe is fixedly connected inside the insulated pipe.

[0008] Preferably, a connecting block is fixedly connected to the outer wall of the fixed tube, and a limiting cylinder is fixedly connected inside the connecting block.

[0009] Preferably, a connecting column is slidably connected inside the limiting cylinder, and a cylindrical block is fixedly connected to the top of the connecting column. The outer wall of the cylindrical block is slidably connected to the inner wall of the limiting cylinder.

[0010] Preferably, a second spring is slidably connected to the outer wall of the connecting column, and the outer wall of the second spring is slidably connected to the inner wall of the limiting cylinder.

[0011] Preferably, a support block is fixedly connected to the bottom end of the connecting column, and the outer wall of the support block is slidably connected to the inner wall of the limiting cylinder.

[0012] Preferably, an L-shaped rod is slidably connected to the lower surface of the support block, and a fixed shaft is slidably connected inside the L-shaped rod, with the outer wall of the fixed shaft fixedly connected to the inside of the limiting cylinder.

[0013] Preferably, a third spring is fixedly connected to the outer wall of the L-shaped rod, and the outer wall of the third spring is fixedly connected to the inner wall of the limiting cylinder.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when the generated fluctuations are transmitted to the second U-shaped block through the insulation pipe, the connecting rod will rotate around the first U-shaped block. Then, the connecting rod will drive the sliding ring to slide on the limiting rod through the first U-shaped block. Under the action of the first spring, the fluctuations generated in the delivery pipeline when the refrigerant is flowing are buffered.

[0016] 2. In this utility model, pulling or pressing the cylindrical block causes the connecting column to slide in the limiting cylinder while the cylindrical block compresses the second spring. The connecting column then drives the L-shaped rod to rotate around the fixed axis through the support block, allowing the L-shaped rod to extend or retract from the limiting cylinder. This enables the entire assembly to be installed or disassembled, achieving the effect of quick installation or disassembly of the pipeline. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a pipeline structure for a liquid helium-free superconducting magnet coil, comprising a fixed tube 1, a fixed block 2 fixedly connected to the inner wall of the fixed tube 1, a limiting rod 12 fixedly connected to the outer wall of the fixed block 2, a first spring 3 and a sliding ring 4 slidably connected to the outer wall of the limiting rod 12, the outer wall of the first spring 3 fixedly connected to the outer wall of the sliding ring 4, a first U-shaped block 5 fixedly connected to the outer wall of the sliding ring 4, a connecting rod 6 rotatably connected to the inside of the first U-shaped block 5, a second U-shaped block 7 rotatably connected to the outer wall of the connecting rod 6, and a conveying assembly provided on the outer wall of the second U-shaped block 7 for conveying refrigerant; the conveying assembly includes an insulation tube 8, the outer wall of the insulation tube 8 fixedly connected to the outer wall of the second U-shaped block 7, and a conveying pipe 9 fixedly connected to the inside of the insulation tube 8.

[0025] Specifically, when the refrigerant vibrates during its flow, the vibrations are transmitted to the second U-shaped block 7 via the insulation pipe 8. The second U-shaped block 7 then drives the connecting rod 6 to rotate around the first U-shaped block 5. The connecting rod 6, through the first U-shaped block 5, causes the sliding ring 4 to slide on the limiting rod 12. By compressing and stretching the first spring 3, the impact force is buffered. The limiting rod 12 supports and limits the sliding ring 4 and the first spring 3. The fixing block 2 supports and fixes the limiting rod 12.

[0026] Reference Figure 1 A connecting block 10 is fixedly connected to the outer wall of the fixed pipe 1, and a limiting cylinder 11 is fixedly connected inside the connecting block 10.

[0027] Specifically, the fixing tube 1 serves to support the fixing connecting block 10, and the connecting block 10 serves to support the fixing limiting cylinder 11.

[0028] Reference Figure 1 , Figure 2 and Figure 4 The limiting cylinder 11 is slidably connected to a connecting column 13. A cylindrical block 14 is fixedly connected to the top of the connecting column 13. The outer wall of the cylindrical block 14 is slidably connected to the inner wall of the limiting cylinder 11. A second spring 15 is slidably connected to the outer wall of the connecting column 13. The outer wall of the second spring 15 is slidably connected to the inner wall of the limiting cylinder 11. A support block 16 is fixedly connected to the bottom end of the connecting column 13. The outer wall of the support block 16 is slidably connected to the inner wall of the limiting cylinder 11. An L-shaped rod 17 is slidably connected to the lower surface of the support block 16. A fixed shaft 18 is slidably connected to the inside of the L-shaped rod 17. The outer wall of the fixed shaft 18 is fixedly connected to the inside of the limiting cylinder 11. A third spring 19 is fixedly connected to the outer wall of the L-shaped rod 17. The outer wall of the third spring 19 is fixedly connected to the inner wall of the limiting cylinder 11.

[0029] Specifically, slightly pulling the cylindrical block 14 causes the connecting column 13 to slide within the limiting cylinder 11. The connecting column 13 then causes the supporting block 16 to slide within the limiting cylinder 11. Under the elastic force of the third spring 19, the L-shaped rod 17 rotates around the fixed shaft 18, which supports and limits the L-shaped rod 17, thus achieving the effect of positioning and fixing the whole. Pressing the cylindrical block 14 compresses the second spring 15 and causes the connecting column 13 to slide within the limiting cylinder 11. The connecting column 13, through the supporting block 16, causes the L-shaped rod 17 to rotate around the fixed shaft 18, allowing the L-shaped rod 17 to retract into the limiting cylinder 11, thus achieving the effect of disassembling the whole.

[0030] Working principle: When this structure is needed, first place the fixing tube 1 at the desired installation location. Under gravity, the L-shaped rod 17 is driven into the groove by the limiting cylinder 11. Slightly pull the cylindrical block 14, which in turn drives the connecting column 13 to slide within the limiting cylinder 11. The connecting column 13 then drives the support block 16 to slide within the limiting cylinder 11. Under the elastic force of the third spring 19, the L-shaped rod 17 rotates around the fixing axis 18, thus positioning and fixing the entire structure. Pressing the cylindrical block 14 compresses the second spring 15, causing the connecting column 13 to slide within the limiting cylinder 11. The connecting column 13, through the support block 16, drives the L-shaped rod 17 to rotate around the fixing axis 18, allowing the L-shaped rod 17 to retract into the limiting cylinder 11. The entire system can then be disassembled. The refrigerant, which needs to be circulated, will flow in the delivery pipe 9, carrying away the heat generated by the superconducting coil. During the flow of the refrigerant, vibrations will occur, and these fluctuations will be transmitted to the second U-shaped block 7 through the insulation pipe 8. The second U-shaped block 7 will then drive the connecting rod 6 to rotate around the first U-shaped block 5. The connecting rod 6 will then drive the sliding ring 4 to slide on the limiting rod 12 via the first U-shaped block 5. The impact force is buffered by compressing and stretching the first spring 3. This structure not only buffers the fluctuations generated by the delivery pipe 9 during refrigerant flow—which may cause pressure and temperature fluctuations—but also effectively absorbs these fluctuations, protecting the integrity and stability of the pipeline system. Stable refrigerant flow also helps improve the cooling effect of the superconducting magnet coil, ensuring the normal operation of the superconducting magnet. Furthermore, it allows for quick installation or disassembly of the pipeline, reducing downtime and maintenance costs. The pipeline can also be reconfigured or expanded as needed.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
