A kind of fluxgate with protective function

Abstract

The invention relates to the technical field of fluxgates, in particular to a fluxgate with a protection function, comprising a main body mechanism, a first protection mechanism, a fixing mechanism, a second protection mechanism and a battery installation mechanism; The first protection mechanism, when the main mechanism is not used to detect the magnetic field of the mine, pulls one end of the first protection mechanism and lays the first protection mechanism on the surface of the main mechanism, thus realizing the protection of the main mechanism and avoiding sand and gravel Scratch the main mechanism, which is beneficial to the observation of the measured data; one end of the first protective mechanism is connected with a fixing mechanism, and the first protective mechanism is fixed by the fixing mechanism after the first protective mechanism is pulled out, and the operation is simple; one side of the main mechanism The second protection mechanism is installed, and the probe line is stored inside the second protection mechanism when not in use, thereby realizing the protection and storage of the probe line and avoiding the looseness of the probe line.

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
