Center regulating rotary table for Helmholtz coil

Abstract

The invention relates to a center regulating rotary table for a Helmholtz coil. The device comprises a main structural frame (29) and an azimuth and lifting frame (37), wherein the main structural frame (29) comprises two circular ring-shaped plates (2) which are coaxially fixed; the circular ring-shaped plates (2) are provided with semicircular holes (49); the peripheral ring-shaped surfaces of the circular ring-shaped plates (2) are provided with grooves around the whole peripheries; the coil is wound in the grooves; the azimuth and lifting frame comprises a height regulating unit, a horizontal azimuth regulating unit and an inclination angle regulating unit; and by the arrangement of the units, high-accuracy three-dimensional continuous regulation on the height, the azimuth of spherical coordinates and the inclination angle position is implemented. The center regulating rotary table for the Helmholtz coil has the advantages that each part of the Helmholtz coil disclosed by the invention is reasonably designed, is simple and convenient to assemble and disassemble, is easy to frequently disassemble and carry and can easily implement omnibearing high-accuracy detection; and the Helmholtz coil disclosed by the invention has field windproof design and has good outdoor use applicability and strong anti-interference performance.

Description

technical field [0001] The invention relates to a coil used in a magenta electromagnetic detection test, in particular, the invention relates to a Helmholtz coil center adjustment turntable. Background technique [0002] Since the space waves to be detected by scientific detection equipment such as space-borne low-frequency magnetic field fluctuation detectors are extremely weak and require extremely high sensitivity and stability, it is necessary to continuously carry out strict various types of performance tests during each stage of development and parameter calibration, etc. At present, it is still difficult to simulate the real space background in the laboratory of the urban environment, and it is also difficult to meet the strict indicators required for detection. For example, the indicators of some low-frequency bands require 10-5nT / Hz1 / 2 indicators, etc. Therefore, it is necessary to simulate a corresponding space electromagnetic environment in a shielded laboratory....

Problems solved by technology

This requires frequent handling, disassembly and assembly of measuring instruments, especially large-scale fixed test equipment such as large-scale Helmholtz coil equipment that is inconvenient to disassemble, which is not conducive to field tests

[0003] In the patent application with the application number 200510117699.0, a detachable Helmholtz coil for field testing is provided, which solves the problem of inconvenient transportation for field testing in the past. The height and azimuth adjustment device at the center of the coil still has a series of problems such as inconvenient use, poor accuracy and inability to continuously change the inclination angle of the measured object when it is used to adjust the height and azimuth position of the measured object.
