Rotating magnetic field loading device with adjustable intensity and direction

Abstract

The invention relates to a rotating magnetic field loading device with adjustable intensity and direction. The rotating magnetic field loading device comprises a magnetic block spacing adjusting mechanism, a magnetic block fixing mechanism, a horizontal rotating mechanism and a vertical rotating mechanism. The magnetic block spacing adjusting mechanism is mounted on the magnetic block fixing mechanism, and is used for applying a load to the to-be-tested workpiece and adjusting the spacing of the magnetic blocks; the horizontal rotating mechanism and the magnetic block fixing mechanism are connected together through two vertical rotating shafts and can rotate relatively; the vertical rotating mechanism is fixedly connected with a vertical rotating shaft and can counteract the rotating power of the vertical rotating shaft, so that the magnetic block fixing mechanism can be fixed at a specific position. A gradient magnetic field surface can be formed, so that the surface of a to-be-tested workpiece is in different magnetic field environments, the defect that an existing device can only research the electrochemical performance of a material under the action of a single surface magnetic field is overcome, and the speed and efficiency can be improved.

[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
