Description

Technical Field

[0001] This application relates to the field of superconducting magnet measurement technology, and in particular to a superconducting magnet magnetic field measurement device. Background Technology

[0002] A superconducting magnet is an electromagnet that uses a type of superconductor with a high transition temperature and a particularly high critical magnetic field to make coils at low temperatures.

[0003] Measuring the magnetic field of a superconducting magnet is an essential step after the manufacture of each superconducting magnet. It is also an important step in verifying whether the design and manufacture of the superconducting magnet meet the requirements for use. Conventional measurement methods mostly measure specific locations or specific paths, which cannot comprehensively measure the magnetic field. In addition, they are cumbersome to use and operate, reducing measurement efficiency. Utility Model Content

[0004] To address the problems that existing methods for measuring the magnetic field of superconducting magnets mostly measure specific locations or paths, failing to provide a comprehensive measurement of the magnetic field, and are cumbersome to use and operate, thus reducing measurement efficiency, this application provides a superconducting magnet magnetic field measuring device.

[0005] The superconducting magnet magnetic field measuring device provided in this application adopts the following technical solution:

[0006] A superconducting magnet magnetic field measuring device includes a support base, a toothed ring fixedly connected to the outer side of the support base, a drive assembly meshing with the outer surface of the toothed ring, a slide fixedly connected to the top of the drive assembly, a measuring groove formed in the middle of the support base, an annular groove formed in the inner wall of a placement platform in the middle of the measuring groove, a slider slidably connected in the annular groove, a bottom end of the slide fixedly connected to the slider, a lifting mechanism mounted above the slide, and a bracket for placing the measuring instrument fixedly at the top of the lifting mechanism.

[0007] Preferably, the drive assembly includes a first motor fixed above the slide table and a gear installed at the output end of the first motor. One side of the gear meshes with a gear ring for transmission, and the output shaft end of the first motor extends through to the outside of the slide table and is fixedly connected to the gear.

[0008] Preferably, a groove is formed on the upper surface of the slide, and a mounting base is fixedly installed inside the groove. A second motor is fixed on one side of the mounting base, and a lead screw is installed at the output end of the second motor. The other end of the lead screw passes through the mounting base and is rotatably connected to the inner wall of the groove, and a movable seat is installed on the outer side by a helical drive.

[0009] Preferably, a limiting rod is symmetrically fixed between the inner wall of the groove and the mounting base, and both ends of the movable base are slidably connected to the limiting rod.

[0010] Preferably, the lifting mechanism includes a base fixedly disposed above the movable seat and an electric push rod mounted on the base, and the bracket is disposed at the top of the output shaft end of the electric push rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This superconducting magnet magnetic field measuring device guides a slider through an annular groove, causing the slider to drive a sliding table to move in a circle along a supporting base. This, in turn, moves the measuring instrument in a circle, enabling the measurement of magnetic field changes around the circumference. A second motor drives a lead screw to rotate, causing a moving seat to slide within a groove, which in turn moves the measuring instrument along with the moving seat, enabling the measurement of magnetic field changes in the horizontal direction. By driving an electric push rod, the measuring instrument can move up and down with the support frame, enabling the measurement of magnetic field changes in the vertical direction. By measuring all data sequentially, the device achieves multi-position measurement, thus improving measurement efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution:

[0019] A superconducting magnet magnetic field measuring device includes a support base 1, a toothed ring 2 fixedly connected to the outer side of the support base 1, a drive assembly meshing on the outer surface of the toothed ring 2, a slide table 3 fixedly connected to the top of the drive assembly, a measuring groove 4 opened in the middle of the support base 1, a placement platform set in the middle of the measuring groove 4, and an annular groove 5 opened in the inner wall, a slide rail fixedly installed in the annular groove 5, a slider 6 slidably connected on the slide rail, one end of the slide table 3 being fixedly connected to the bottom of the slider 6, a lifting mechanism installed above the slide table 3, and a bracket 7 for placing the measuring instrument fixedly at the top of the lifting mechanism.

[0020] The drive assembly includes a first motor 8 fixed above the slide table 3 and a gear 9 installed at the output end of the first motor 8. One side of the gear 9 meshes with the gear ring 2 for transmission, and the output shaft end of the first motor 8 extends through to the outside of the slide table 3 and is fixedly connected to the gear 9.

[0021] The upper surface of the slide table 3 has a groove 10, and a mounting base is fixedly installed inside the groove 10. A second motor 11 is fixed on one side of the mounting base. A lead screw 12 is installed at the output end of the second motor 11. The other end of the lead screw 12 passes through the mounting base and is rotatably connected to the inner wall of the groove 10. A movable seat 13 is installed on the outer side by a screw drive.

[0022] A limiting rod 14 is symmetrically fixed between the inner wall of the groove 10 and the mounting base. The two ends of the movable base 13 are slidably connected to the limiting rod 14. The limiting rod 14 limits the movement and ensures the stability during measurement.

[0023] The lifting mechanism includes a base fixedly mounted above the movable seat 13 and an electric push rod 15 mounted on the base. The bracket 7 is located at the top of the output shaft end of the electric push rod 15.

[0024] During measurement, the superconducting magnet is placed on the platform, and the measuring instrument is placed on the support 7. Discharging the superconducting magnet with an external power source generates a magnetic field at its center. A drive assembly is used to start the first motor 8, which drives the gear 9 to rotate. Under the meshing of the gear ring 2, the gear 9 moves the slide table 3, which in turn moves the slider 6. The slider 6 is guided by the annular groove 5, causing it to move the slide table 3 in a circular motion along the support base 1. This causes the measuring instrument to move in a circular motion, allowing for the measurement of circumferential magnetic field changes. A second motor 11 drives the lead screw 12 to rotate, causing the moving seat 13 to slide within the groove 10. This causes the measuring instrument to move along with the moving seat 13, allowing for the measurement of horizontal magnetic field changes. Driving the electric push rod 15 allows the measuring instrument to move up and down with the support 7, allowing for the measurement of vertical magnetic field changes. All data are measured sequentially, achieving multi-position measurement and improving measurement efficiency.
