Abstract

The invention is a rotating magnetic field loading device with adjustable strength and direction, which includes a magnetic block spacing adjustment mechanism, a magnetic block fixing mechanism, a horizontal rotation mechanism and a vertical rotation mechanism; the magnetic block spacing adjustment mechanism is installed on the magnetic block fixing mechanism , to apply a load to the workpiece to be tested, and adjust the distance between the magnetic blocks; the horizontal rotation mechanism and the magnetic block fixing mechanism are connected together through two vertical rotation shafts, and the two can rotate relative to each other; the vertical rotation mechanism is fixedly connected to a vertical rotation shaft, which can Offset the power of the rotation of the vertical rotation axis, so that the magnetic block fixing mechanism can be fixed at a specific position. The inclined magnetic field surface can be formed, so that the surface of the workpiece to be tested is in different magnetic field environments, which overcomes the defect that the existing device can only study the electrochemical performance of a single surface of the material under the magnetic field, and can improve the speed and efficiency.

[0003] Research on the performance of energy materials under adjustable magnetic fields of angle and size will involve in-situ application of magnetic fields of different directions and sizes. For example, when studying the electrochemical performance of energy materials in a magnetic field environment, different magnetic field directions and different sizes of magnetic fields It will lead to different directions and distances of charge movement of energy materials, which in turn will lead to different electrochemical properties of energy materials

At present, rotating samples are generally used to change the magnetic field angle. For example, a "device for adjusting the loading angle between samples and bias magnetic fields" disclosed in Chinese patent documents, the announcement number of which is CN 210572101U, includes material placement tables, driving gears, The driven gear, the rotating rod and the casing, the experimental sample needs to be fixed on the material placement table during the experiment, and then according to the experimental requirements, the lower shaft knob is rotated to drive the driven gear and the rotating rod to rotate by controlling the driving gear to realize the experimental sample. To adjust the horizontal angle, rotating the upper shaft knob can drive the rotation of the material placement table in the vertical direction by controlling the rotation of the upper shaft, and realize the adjustment of the vertical angle of the sample. This method cannot be used for experiments on non-solid materials, and requires An additional magnetic field source is set, so it is necessary to design a rotating magnetic field loading device that can adjust the angle of the magnet, change the size of the magnetic field, and make the material interact with the external physical field
