Description

Technical Field

[0001] The present invention relates to the technical field of superconducting magnet skeletons, and specifically, to a connection structure for superconducting magnet skeletons. Background Art

[0002] As a key support structure of superconducting magnets, superconducting magnet skeletons play a crucial role in the application of superconducting technology. It not only needs to have sufficient strength and stability to support the weight of superconducting coils and resist external stresses, but also needs to ensure that the superconducting coils can maintain precise geometric shapes and positions during operation, so as to ensure the uniformity and stability of the magnetic field. In addition, the superconducting magnet skeletons also need to have good heat conduction performance to timely dissipate the heat generated by the superconducting coils during operation, preventing performance degradation or damage caused by local overheating.

[0003] In the existing connection technologies for superconducting magnet skeletons, although there are already some connection schemes for ensuring the internal sealing of the skeleton main body, these schemes still have some deficiencies in practical applications. The existing connection methods are often more complex in operation, which not only increases the difficulty of installation and maintenance, but also may lead to connection failure due to improper operation. Especially for those connection components that require precise alignment and fastening, once there is a deviation during the installation process, it may affect the overall sealing effect and the stability of the structure. Summary of the Invention

[0004] Technical Problems to be Solved

[0005] The purpose of the present invention is to make up for the deficiencies of the existing technology, and provide a connection structure for superconducting magnet skeletons. By setting a connection mechanism, impurities are avoided from entering during use. The connection mechanism is connected to the joint plate in a rotating manner, so as to achieve the purpose of connecting with the skeleton main body; by setting the mutual cooperation of the pressing plate and the tooth groove, the purpose of limiting the clamping plate can be achieved, avoiding rotation and thus affecting the sealing between the cover plate and the joint plate.

[0006] Technical Solutions

[0007] To achieve the above purpose, the present invention provides the following technical solutions: a connection structure for superconducting magnet skeletons, including a skeleton mechanism. The skeleton mechanism includes a skeleton main body, and joint plates are fixedly connected to both ends of the skeleton main body. A loose flange is fixedly connected to one side of the outer wall of the skeleton main body where one of the joint plates is located, and a fixed flange is fixedly connected to one side of the outer wall of the skeleton main body where the loose flange is located. A connection mechanism for establishing a connection with the skeleton main body is provided on one side of one of the joint plates away from the loose flange.

[0008] As described above, the connecting mechanism includes a cover plate placed on the outer wall of one of the joint plates. Symmetrically fixed to the outer walls of both the cover plate and the joint plate are clamping plates. Tooth grooves are provided on the outer walls of several of the clamping plates. The clamping plates on the outer walls of the cover plate and the joint plate are arranged in an alternating manner. Symmetrically fixed to the outer walls of both the cover plate and the joint plate are clamping frames.

[0009] As described above, the clamping frames on the outer walls of the cover plate and the joint plate are arranged in an alternating manner. Moreover, the clamping plates on the outer wall of the joint plate are slidably sleeved inside the clamping frames on the outer wall of the cover plate, and the clamping plates on the outer wall of the cover plate are slidably sleeved inside the clamping frames on the outer wall of the joint plate.

[0010] As described above, at positions corresponding to the tooth grooves of several of the clamping frames, there are pressure plates magnetically attracted to prevent the clamping plates from falling off. Fixed to the middle of the outer wall of the pressure plate is a lifting rod.

[0011] As described above, on one side of the cover plate close to the skeleton main body, a sealing groove is provided. Inside the sealing groove is placed a sealing ring that forms a sealed connection with the joint plate.

[0012] As described above, a non-winding area is formed between the joint plate close to the loose flange side and the fixed flange, and a winding area for placing the coil is formed between the joint plate close to the connecting mechanism side and the loose flange.

[0013] As described above, several through holes are evenly provided at positions of the outer wall of the skeleton mechanism in the winding area. On the outer wall of the loose flange, there are several wire passing grooves facilitating the coil to pass through.

[0014] Advantages:

[0015] Compared with the prior art, the connection structure for the superconducting magnet skeleton has the following advantages:

[0016] First, by providing a connecting mechanism, during use, the connection with the skeleton mechanism can be achieved through the connecting mechanism, thereby ensuring the sealing inside the skeleton main body and preventing impurities from entering during use. The connecting mechanism is connected to the joint plate in a rotating manner to achieve the purpose of connecting with the skeleton main body.

[0017] Second, by providing the mutual cooperation of the pressure plate and the tooth grooves, the purpose of limiting the clamping plates can be achieved, avoiding rotation and thus affecting the seal between the cover plate and the joint plate.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1-5 shown, the present invention provides a technical solution: a connection structure for a superconducting magnet skeleton, including a skeleton mechanism 1. The skeleton mechanism 1 includes a main body of the skeleton 11. Both ends of the main body of the skeleton 11 are fixedly connected with joint plates 15. A loose flange 12 is fixedly connected to the outer wall of the main body of the skeleton 11 on one side of one of the joint plates 15. A fixed flange 13 is fixedly connected to the outer wall of the main body of the skeleton 11 on one side of the loose flange 12. A connection mechanism 2 for establishing a connection with the main body of the skeleton 11 is provided on one side of one of the joint plates 15 away from the loose flange 12.

[0027] It should be noted that the main body of the framework 11, as the core component, is fixedly connected to the joint plates 15 at both ends, which not only enhances the stability of the overall structure but also provides a reliable interface for subsequent connections. The introduction of the connecting mechanism 2 greatly improves the connection efficiency and sealing performance between the main body of the framework 11 and other components. By establishing a tight connection with the main body of the framework 11, it ensures the stability and safety of the superconducting magnet framework during operation. At the same time, the design of the connecting mechanism 2 also takes into account the requirements of easy installation and disassembly, making the entire connection structure more flexible and convenient during use.

[0028] As Figures 3-5 shown, the connecting mechanism 2 includes a cover plate 21 placed on the outer wall of one of the joint plates 15. Symmetrically fixed to the outer walls of both the cover plate 21 and the joint plate 15 are clamping plates 24. A plurality of tooth grooves 241 are formed on the outer walls of the clamping plates 24. The clamping plates 24 on the outer walls of the cover plate 21 and the joint plate 15 are arranged in a staggered manner. Symmetrically fixed to the outer walls of both the cover plate 21 and the joint plate 15 are clamping frames 25. The clamping frames 25 on the outer walls of the cover plate 21 and the joint plate 15 are arranged in a staggered manner. Moreover, the clamping plates 24 on the outer wall of the joint plate 15 are slidably sleeved inside the clamping frames 25 on the outer wall of the cover plate 21, and the clamping plates 24 on the outer wall of the cover plate 21 are slidably sleeved inside the clamping frames 25 on the outer wall of the joint plate 15. At the positions corresponding to the tooth grooves 241 of a plurality of clamping frames 25, there is a pressing plate 26 magnetically attracted to prevent the clamping plates 24 from falling off. Fixed to the middle of the outer wall of the pressing plate 26 is a lifting rod 27.

[0029] It should be noted that the staggered arrangement of the clamping plates 24 and the clamping frames 25 and their sliding sleeves between each other achieve an efficient and stable connection between the cover plate 21 and the joint plate 15, which not only simplifies the installation process but also greatly improves the reliability and durability of the connection. The cooperation between the tooth grooves 241 formed on the outer walls of the clamping plates 24 and the clamping frames 25 effectively prevents the clamping plates 24 from sliding or falling off during the connection process, thus ensuring the stability and durability of the connection. At the same time, the design of the tooth grooves 241 also enhances the biting force between the clamping plates 24 and the clamping frames 25, making the connection tighter and more secure. The pressing plate 26 is firmly adsorbed on the clamping frames 25 through magnetic attraction at the positions corresponding to the tooth grooves 241, effectively preventing the clamping plates 24 from accidentally falling off during the connection process.

[0030] As Figure 3 and Figure 4 shown, a sealing groove 22 is formed on the side of the cover plate 21 close to the main body of the framework 11. Inside the sealing groove 22, there is a sealing ring 23 that forms a sealed connection with the joint plate 15.

[0031] It should be noted that a sealing groove 22 is provided on the side of the cover plate 21 close to the main body of the skeleton 11, and a sealing ring 23 is carefully placed in this groove. This design greatly enhances the sealing performance between the connecting mechanism 2 and the joint plate 15. The precise dimensions and shape of the sealing groove 22 ensure that the sealing ring 23 can be completely embedded and closely fitted, thus effectively preventing the infiltration of external impurities, gases or liquids, and protecting the purity and stability of the internal environment of the superconducting magnet skeleton.

[0032] As Figure 1 and Figure 2 shown, a non-winding area 14 is formed between the joint plate 15 close to the loose flange 12 and the fixed flange 13, and a winding area 17 for placing the coil is formed between the joint plate 15 close to the connecting mechanism 2 and the loose flange 12. A number of through holes 16 are evenly provided at the position of the outer wall of the skeleton mechanism 1 in the winding area 17, and a number of wire passing grooves for facilitating the coil to pass through are provided on the outer wall of the loose flange 12.

[0033] It should be noted that the non-winding area 14 formed between the joint plate 15 close to the loose flange 12 and the fixed flange 13 provides an important space optimization for the structural design of the superconducting magnet skeleton. The design of this area avoids the winding of the coil, ensures the neatness of the skeleton structure and the rationality of the layout, and at the same time reduces the possibility of electromagnetic interference and improves the overall performance of the superconducting magnet.

[0034] Working principle: When it is necessary to connect the cover plate 21 with the joint plate 15, first ensure that the clamping plates 24 on the cover plate 21 and the clamping plates 24 on the joint plate 15 are arranged staggeredly, so that the clamping plates 24 can be embedded into the inside of the clamping frames 25 of each other to form a preliminary connection. Subsequently, by rotating the cover plate 21, the tooth grooves 241 on the clamping plates 24 cooperate with the clamping frames 25, further enhancing the stability of the connection. During the rotation process, due to the meshing effect of the tooth grooves 241 and the clamping frames 25, the connection between the cover plate 21 and the joint plate 15 becomes tighter. At the same time, in order to prevent the clamping plates 24 from falling off during the rotation process, a pressing plate 26 is provided. The pressing plate 26 is fixed on the clamping frame 25 by magnetic attraction, corresponding to the position of the tooth groove 241, thus effectively restricting the movement of the clamping plate 24. The setting of the lifting rod 27 facilitates the installation and disassembly of the pressing plate 26 by the user. In addition, a sealing groove 22 is opened on the side of the cover plate 21 close to the skeleton main body 11, and a sealing ring 23 is placed therein. When the cover plate 21 is tightly connected to the joint plate 15, the sealing ring 23 can effectively prevent external impurities from entering the inside of the skeleton main body 11, ensuring its sealing performance. In the design of the skeleton mechanism 1, a non-winding area 14 is formed between the joint plate 15 close to the loose flange 12 and the fixed flange 13, while a winding area 17 for placing the coil is formed between the joint plate 15 close to the connecting mechanism 2 and the loose flange 12. The through holes 16 on the winding area 17 facilitate the placement and fixation of the coil.

[0035] It should be understood that in the development process of any actual implementation mode, in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine work of design, manufacturing and production.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
