Description

Technical Field

[0001] The invention relates to the technical field of magnetometers, in particular to a portable magnetometer for magnetic detection. Background Art

[0002] The optical pumping magnetometer is based on the Zeeman splitting of atoms of helium, mercury, nitrogen, hydrogen, and alkali metals such as rubidium and cesium in an external magnetic field, and is developed using optical pumping and magnetic resonance technology. It uses the magnetic moment of the arranged atoms to produce a resonant absorption effect under the action of an alternating electromagnetic field of a specific frequency, disrupting the arrangement of the atoms. The frequency of the electromagnetic field where the resonant absorption phenomenon occurs is proportional to the strength of the external magnetic field at the point where the sample is located to obtain data.

[0014] The beneficial effects of the present invention are embodied in: 1. The portable magnetometer for magnetic detection is provided with a folding bracket. When the pull rod is pushed into the storage box, the connecting rod pushes the sliding block inside the lower slide rail to move, so that the two ends of the bottom of the folding bracket are close to each other, so that the folding bracket is extended, the lifting plate is pushed out of the storage box, and the magnetometer body is pushed out of the storage box.

When the bidirectional screw is rotated, the two displacement blocks on the same bidirectional screw are brought close to each other, so that the support rod pushes the displacement plate to move, and the moving wheel is pushed out of the through hole, so that the moving wheel moves to the outside of the retractable box, so that the storage box can store the magnetometer body and then move it through the moving wheel.

[0016] 3. This portable magnetometer for magnetic detection is provided with two transmission wheels and a transmission belt. When the push rod is pushed into the storage slot of the storage box, the connecting rod is driven to move, thereby causing the transmission belt to rotate, and the bidirectional lead screw is driven to rotate through the second transmission wheel, thereby causing the two displacement blocks on the same bidirectional lead screw to move away from each other, and the moving wheel is put into the retractable box through the through hole. Conversely, when the pull rod is pulled out, the folding bracket contracts to put the magnetometer body into the storage box, while causing the transmission belt to reverse, thereby causing the moving wheel to be pushed out from the through hole, thereby facilitating the movement of the magnetometer body after storage.

[0017] 4. This portable magnetometer for magnetic detection is equipped with a synchronous wheel and a synchronous belt. When the transmission belt drives the bidirectional lead screw located below to rotate, the synchronous wheel and the synchronous belt drive another bidirectional lead screw located above to rotate synchronously, thereby making the two bidirectional lead screws rotate synchronously and push the displacement plate to move.
