Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting coils, and particularly to a skeleton structure with a magnetic conduction function. Background Technique

[0002] During the winding process of the heat-conducting coil, the skeleton, as the main structural component for carrying the superconducting coil, plays key roles such as coil winding and forming, fixing of superconducting joints, and installation of accessories. In order to concentrate and guide the magnetic field, the skeleton of the heat-conducting coil usually has the function of magnetic conduction to improve the heat transfer efficiency of the heat-conducting coil.

[0003] The authorized announcement number CN210606846U provides a winding skeleton structure for a superconducting magnet coil, which includes a skeleton central tube. Coaxial end plates are respectively arranged at both ends of the skeleton central tube, and a threaded structure is arranged on the winding surface of the skeleton central tube; the surface of the skeleton central tube is sprayed with ceramics for insulating isolation between the coil and the skeleton.

[0004] The outer wall of the existing winding skeleton is a smooth arc surface. During the winding process, the gap between each turn of the conductor cannot be controlled evenly, which will lead to uneven magnetic field distribution, thereby affecting the performance of the magnetic conduction function. The uneven heat distribution will reduce the heat transfer efficiency, and the reduction of the overall heat conduction efficiency will also cause an increase in local heat, resulting in local overheating. Therefore, the present application provides a skeleton structure with a magnetic conduction function to meet the requirements. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a skeleton structure with a magnetic conduction function to solve the problem that the outer wall of the existing winding skeleton is a smooth arc surface, and the gap between each turn of the conductor cannot be controlled evenly during the winding process, which will lead to uneven magnetic field distribution and thus affect the performance of the magnetic conduction function as described in the above background technique.

[0006] To solve the above technical problem, the utility model provides the following technical solutions:

[0007] A skeleton structure with a magnetic conduction function includes a winding shaft body. The cross-section of the winding shaft body is elliptical. Two magnetic conduction metal strips are installed through the inside of the winding shaft body. The two magnetic conduction metal strips are located on the major axis of the cross-section of the winding shaft body and are symmetric with respect to the axis of the inner wall of the winding shaft body. A plurality of deep wire grooves are formed on the outer wall of the winding shaft body, and a plurality of shallow wire grooves are formed on the outer wall of the winding shaft body. An internal thread one is formed on the inner wall of the winding shaft body, and an external thread one is formed on the outer wall of the winding shaft body. One end of the winding shaft body is threadedly connected to a connection disk one, and an external thread two that cooperates with the internal thread one is fixedly installed on the connection disk one. The other end of the winding shaft body is threadedly connected to a connection disk two, and an internal thread two that cooperates with the external thread one is formed on the connection disk two.

[0008] Preferably, four fixing members are fixedly installed on the outer wall of the winding shaft body, and every two of the fixing members are located on the same horizontal straight line.

[0009] Preferably, a ceramic tube is fixedly connected to the inner wall of the winding shaft body.

[0010] Preferably, a plurality of groups of fixing grooves are formed through the first connecting disc and the second connecting disc.

[0011] Preferably, an opening groove is formed on one side of the fixing groove.

[0012] Preferably, a circular chamfer is provided at the edge of the opening groove.

[0013] Preferably, one side of the two fixing members is in contact with one side of the first connecting disc.

[0014] Preferably, one side of the other two fixing members is in contact with one side of the second connecting disc.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] In the above solution, by providing the deep wire grooves and the shallow wire grooves, the heat-conducting coil is more firmly and stably wound on the outer wall of the winding shaft body, reducing the stress and deformation on the surface of the coil, contributing to improving the service life and stability of the heat-conducting coil. At the same time, the uniformly arranged heat-conducting coils make the heat more evenly distributed, effectively reducing the temperature gradient on the surface of the coil and reducing the phenomena of local overheating and heat concentration, thereby improving the heat transfer efficiency.

[0017] By providing the fixing members, the winding shaft body is perpendicular to both the first connecting disc and the second connecting disc, ensuring the connection strength and stability. When using multiple winding shaft bodies to complete the coil winding, the fixing members play a role in positioning the coil, and play a role in dividing and positioning the coils with a long axial distance of winding, thereby ensuring the stability and uniformity during the coil winding.

[0018] By providing the fixing grooves, the ends of the coils are fixed, so that the part of the coil wound on the winding shaft body will not shift, ensuring the stability of the overall structure of the coil, avoiding the coil from falling off or moving, and maintaining the safety of the coil. By providing the opening grooves, it is convenient to clamp the ends of the coils inside the fixing grooves. The chamfer at the edge of the opening groove avoids damaging the outer wall of the coil, and when the winding shaft body is placed horizontally, due to the opening of the opening grooves, the winding shaft body can be placed stably to avoid rolling.

[0031] As Figures 1-5 shown, an embodiment of the present utility model provides a skeleton structure with a magnetic conduction function, including a winding shaft body 1. The cross-section of the winding shaft body 1 is elliptical. Two magnetic conduction metal bars 2 are installed through the inside of the winding shaft body 1. The two magnetic conduction metal bars 2 are located on the major axis of the cross-section of the winding shaft body 1 and are symmetric with respect to the axis of the inner wall of the winding shaft body 1. A plurality of deep wire grooves 3 are provided on the outer wall of the winding shaft body 1, and a plurality of shallow wire grooves 4 are provided on the outer wall of the winding shaft body 1. An internal thread one 6 is provided on the inner wall of the winding shaft body 1, and an external thread one 7 is provided on the outer wall of the winding shaft body 1. One end of the winding shaft body 1 is threadedly connected to a connection plate one 9. An external thread two 11 that mates with the internal thread one 6 is fixedly installed on the connection plate one 9. The other end of the winding shaft body 1 is threadedly connected to a connection plate two 10. An internal thread two 12 that mates with the external thread one 7 is provided on the connection plate two 10. Four fixing members 5 are fixedly installed on the outer wall of the winding shaft body 1. The four fixing members 5 are respectively arranged at both ends of the outer wall of the winding shaft body 1. Every two fixing members 5 are located on the same horizontal straight line. One side of two fixing members 5 is in contact with one side of the connection plate one 9, and one side of the other two fixing members 5 is in contact with one side of the connection plate two 10. A ceramic tube 8 is fixedly connected to the inner wall of the winding shaft body 1. A plurality of fixing grooves 13 are provided through the connection plate one 9 and the connection plate two 10. An opening groove 14 is provided on one side of the fixing groove 13, and a circular chamfer is provided at the edge of the opening groove 14.

[0032] When winding the heat-conducting coil, an appropriate amount of winding shaft bodies 1 are selected according to the length of the coil to be wound. The internal thread 1-6 and the external thread 1-7 on one side of each winding shaft body 1 can be fitted and installed. The magnetic conductive metal strip 2 enables the magnetic field to be evenly distributed inside the coil, improving the magnetic field transmission efficiency. The magnetic conductive metal strip 2 concentrates the magnetic field lines and reduces the magnetic leakage phenomenon of the magnetic field. Then, the external thread 2-11 rotates relative to the internal thread 1-6 to fix the connecting plate 1-9 to one end of the winding shaft body 1, and the internal thread 2-12 rotates relative to the external thread 1-7 to fix the connecting plate 2-10 to the other end of the winding shaft body 1. One end of the coil is clamped inside the fixing groove 13, and then the coil is wound. First, the coil is wound along the trend of the deep wire groove 3 on the outer wall of the winding shaft body 1. Since the groove position of the deep wire groove 3 is deeper than that of the shallow wire groove 4, after the coil is completely wound along the deep wire groove 3, it is wound along the outer wall of the shallow wire groove 4. By setting the deep wire groove 3 and the shallow wire groove 4, the heat-conducting coil is more firmly and stably wound on the outer wall of the winding shaft body 1, reducing the stress and deformation on the surface of the coil, which helps to improve the service life and stability of the heat-conducting coil. At the same time, the evenly arranged heat-conducting coils make the heat more evenly distributed, effectively reducing the temperature gradient on the surface of the coil and reducing the phenomena of local overheating and heat concentration, thereby improving the heat transfer efficiency. When using one winding shaft body 1 to complete the coil winding, the four fixing parts 5 contact one side of the connecting plate 1-9 and the connecting plate 2-10, playing a positioning role between the winding shaft body 1, the connecting plate 1-9 and the connecting plate 2-10, so that the winding shaft body 1 is perpendicular to both the connecting plate 1-9 and the connecting plate 2-10, ensuring the connection strength and stability. When using multiple groups of winding shaft bodies 1 to complete the coil winding, the setting of the fixing parts 5 has a positioning effect on the coil, playing a role of dividing and positioning for the coil with a long winding axial distance, thereby ensuring the stability and uniformity during coil winding. By setting the ceramic tube 8, the ceramic tube 8 has good insulation performance and relatively high hardness, thus playing a supporting role for the winding shaft body 1 to prevent the winding shaft body 1 from deforming due to excessive winding of the coil on its outer wall. The other end of the wound coil is pulled from the opening of the opening groove 14 to the inside of the fixing groove 13. By setting the fixing groove 13, the end of the coil is fixed, so that the part of the coil wound on the winding shaft body 1 will not shift, ensuring the overall structural stability of the coil, preventing the coil from falling off or moving, and maintaining the safety of the coil. By setting the opening groove 14, it is convenient to clamp the end of the coil inside the fixing groove 13. The chamfer at the edge of the opening groove 14 avoids damaging the outer wall of the coil, and when the winding shaft body 1 is placed horizontally, due to the opening of the opening groove 14, the winding shaft body 1 can be placed stably and avoid rolling.

[0033] For the technical solution provided by the present utility model, when winding the heat-conducting coil, an appropriate amount of winding shaft bodies 1 are selected according to the length of the coil to be wound. The internal thread one 6 and the external thread one 7 on one side of each winding shaft body 1 can be fitted and installed. Then, the external thread two 11 rotates relative to the internal thread one 6 to fix the connecting plate one 9 to one end of the winding shaft body 1, and the internal thread two 12 rotates relative to the external thread one 7 to fix the connecting plate two 10 to the other end of the winding shaft body 1. One end of the coil is clamped inside the fixing groove 13, and then the coil is wound. First, the coil is wound along the outer wall of the winding shaft body 1 according to the trend of the deep wire groove 3. Since the groove position of the deep wire groove 3 is deeper than that of the shallow wire groove 4, after the coil is completely wound according to the deep wire groove 3, it is wound along the outer wall of the shallow wire groove 4. The four fixing members 5 contact one side of the connecting plate one 9 and the connecting plate two 10, so that the winding shaft body 1 is perpendicular to both the connecting plate one 9 and the connecting plate two 10. The other end of the wound coil is pulled from the opening of the opening groove 14 into the inside of the fixing groove 13.
