[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Reference Figure 1-5 The first embodiment of the present invention provides a support device for low temperature testing of a superconducting magnet, wherein the device has a reference axis 1 in position, and the reference axis 1 is a fixed straight line direction. In addition, the device also includes:

[0030] There are multiple support wheels 2, which are configured to move away from or converge synchronously with respect to the reference axis 1, and the support wheels 2 can rotate around their own axes;

[0031] A packaging part, which is used to cooperate with the skeleton of the superconducting magnet to form a storage cavity, and the storage cavity is used to accommodate a refrigeration medium (liquid helium);

[0032] A test element 3, which is fixedly arranged at the reference axis 1, and the test element 3 can be a Hall element;

[0033] like Figure 5 As shown, in the process of realizing superconducting magnet measurement of the present invention, the superconducting magnet skeleton is mounted on a plurality of support wheels 2, and the plurality of support wheels 2 are spaced apart from each other with the reference axis 1 as the center, thereby supporting the skeleton of the superconducting magnet. Through the structure of the support wheels 2, the skeleton can rotate around the reference axis 1, and the geometric center of the skeleton is maintained at the reference axis 1. When the magnetic field center is at the geometric center of the skeleton, the magnetic field size at the reference axis 1 will not change as the skeleton rotates. On the contrary, when there is a deviation, the magnetic field strength changes, thereby realizing the measurement of the magnetic field center position.

[0034] Further, see Figure 1 and Figure 2 The present invention also includes a base 4, on which at least two moving parts 5 are slidably arranged, and the moving parts 5 are circular. The reference axis 1 passes through the centers of the two moving parts 5, and a plurality of the support wheels 2 are evenly distributed on the two moving parts 5. The support wheels 2 can move away from or towards each other in a divergent manner compared to the center of the moving parts 5. Through the cooperation of the two moving parts 5, the two support wheels 2 can be moved away from or towards each other horizontally at the same time, so as to realize the placement and removal of the superconducting magnet skeleton on the device.

[0035] Further, see Figure 1 and Figure 2 Regarding the activity mode of the support wheel 2 on the moving part 5, specifically, the present invention also includes a sliding block 6 and a driving shaft 7 corresponding to the roller, the roller and the sliding block 6 are rotatably matched, the sliding block 6 is slidably set on the moving part 5, the driving shaft 7 is rotatably set on the moving part 5, and is rotatably matched with the sliding block 6. When the driving shaft 7 rotates, it drives the sliding block 6 to move, thereby realizing the movement of the support wheel 2. A driving mechanism is provided on the moving part 5, which is used to drive the driving shaft 7 to rotate, thereby realizing the mutual movement of multiple support wheels 2.

[0036] Further, see Figure 1-4 The driving mechanism includes an electric push rod 8 fixedly arranged on the moving part 5, and also includes a pushing block 9 slidably arranged on the moving part 5. The pushing block 9 is connected to the electric push rod 8 and cooperates with the teeth of the driving shaft 7 to achieve a transmission effect between the driving shaft 7 and the driving shaft 7. When the pushing block 9 moves under the action of the electric push rod 8, it drives the driving shaft 7 to rotate.

[0037] Further, see Figure 1-3 The packaging part includes cover plates 10 respectively arranged on the two moving parts 5. When the two moving parts 5 are brought closer together, the two cover plates 10 respectively cover the two ends of the skeleton of the superconducting magnet to form a storage cavity, and at least one of the moving parts 5 is provided with a liquid inlet 11 for the entry and extraction of liquid helium.

[0038] Further, see Figure 1-3 The cover plate 10 is rotatably matched with the moving part 5 so that the cover plate 10 can rotate synchronously with the frame. When the frame rotates, it will not be subject to friction resistance from the cover plate 10.

[0039] Further, see Figure 1 and Figure 2 A support 12 is slidably provided on the base 4, and the support 12 corresponds to the moving part 5 and is fixedly connected to the moving part 5, so as to realize the moving effect of the moving part 5 on the base, and a driving force acting on the support 12 is configured on the base 4, so as to meet the movement requirements of the moving part 5 when the skeleton is installed on the device.

[0040] Further, see Figure 1 A support rod 13 is rotatably provided on the base 4, and the support 12 is threadedly matched with the support rod 13. When the support rod 13 is rotated, the movement of the two supports 12 can be realized synchronously.

[0041] Furthermore, for the power supply method of the superconducting magnet, the cover plate 10 can be provided with a corresponding electrical connection mechanism, such as a socket structure, etc., and the cover plate 10 and the moving part 5 can be connected in circuit via a conductive slip ring mechanism.

[0042] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
