Fluxgate with protection function

Abstract

The invention relates to the technical field of fluxgates, in particular to a fluxgate with a protection function, which comprises a main body mechanism, a first protection mechanism, a fixing mechanism, a second protection mechanism and a battery mounting mechanism, the first protection mechanism is installed on the side face of the main body mechanism, when the main body mechanism is not used for detecting the magnetic field of the mine, one end of the first protection mechanism is pulled, the first protection mechanism is laid on the surface of the main body mechanism, protection of the main body mechanism is achieved, the main body mechanism is prevented from being scratched by gravel, and observation of measured data is facilitated; one end of the first protection mechanism is connected with the fixing mechanism, the first protection mechanism is fixed through the fixing mechanism after the first protection mechanism is pulled out, and operation is easy; the second protection mechanism is mounted on one side of the main body mechanism, and the probe wire is stored in the second protection mechanism when the probe wire is not used, so that the probe wire is protected and stored, and the probe wire is prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of fluxgates, in particular to a fluxgate with protection function. Background technique [0002] A fluxgate is a magnetic field measurement element that can be used in current measurement with high precision; the working principle of a fluxgate sensor is the same as that of a current sensor based on the Hall effect: the magnetic field generated by the primary current to be measured is generated by Specific sensing element detection. The fluxgate design is similar to that of a closed-loop Hall-effect current sensor, except that this approach uses a saturable inductor in the air gap instead of a Hall-effect sensor; The probe of the printed board, two sensor circuit boards, support tubes and fasteners, input and output connectors, a probe is installed in parallel between the two sensor circuit boards through the support tube and fasteners, and the two sensor circuit boards are connected by soldering. One end...

Problems solved by technology

[0003] At present, when the fluxgate used for mine detection is in use, the display screen is in a state of leakage. The rubber protective cover of the fluxgate can only protect the surroundings of the fluxgate, and the display screen is not protected. It has been used for a long time The fluxgate used in the mine has a lot of dust, which is easy to cause scratches on the display screen, and if the fluxgate falls during use, it may easily cause the display screen to be broken, which is also not conducive to the observation of the detected data; and the probe connected to the fluxgate The wire and the fluxgate are set separately, the probe wire is difficult to store inside the fluxgate when not in use, and it is inconvenient to store the probe
