Description

Technical Field

[0001] The utility model relates to the technical field of ferromagnetic detection, in particular to a double-column ferromagnetic detection device. Background Art

[0002] In the early 1930s, fluxgate technology appeared, which can measure constant and low-frequency weak magnetic fields. Its basic principle is to use the induction coil made of soft magnetic material core with high magnetic permeability and low coercivity to produce the potential characteristics of even harmonic components that vary with the ambient magnetic field after being excited. The even harmonic components are measured by a high-performance fluxgate conditioning circuit, thereby measuring the size of the ambient magnetic field. The fluxgate sensor is a sensor that measures weak magnetic fields by using the nonlinear relationship between the magnetic induction intensity and the magnetic field intensity of the high-permeability core in the measured magnetic field under the saturation excitation of the alternating magnetic field. Compared with other types of magnetic measuring instruments, fluxgate sensors have the characteristics of high resolution, wide range of weak magnetic field measurement, reliability, and the ability to directly measure the components of the magnetic field.

[0003] After searching, a patent with publication number CN210401704U discloses a movable ferromagnetic detection device, including a base and a ferromagnetic detector body, the top of the base is fixedly connected to a fixing frame, and the surface of the fixing frame is connected to the ferromagnetic detector body, the corresponding two side walls of the ferromagnetic detector body are fixedly connected to fixing plates, and a clamping rod is provided on one side of the fixing plate close to the fixing frame, and clamping grooves are symmetrically opened on the surface of the fixing frame.

[0004] Existing equipment uses a single ferromagnetic detector body to detect passing metal objects, which makes it impossible to distinguish the approximate location of the metal objects and increases the steps of subsequent investigation. Therefore, we propose a double-column ferromagnetic detection device to solve the above problem. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a double-column ferromagnetic detection device, comprising two columnar detection rods, two magnetic flux current sensors are evenly installed at one end of the two columnar detection rods close to each other, and a spacing adjustment structure is installed between the two columnar detection rods;

[0007] The spacing adjustment structure includes two telescopic rods whose one end is installed on the top of the corresponding columnar detection rod by bolts, and the ends of the two telescopic rods close to each other are installed with storage rods by plugging, and the front of the storage rods is installed with alarm components;

[0008] The alarm component includes a device box whose rear end is installed on the storage rod by bolts, a display screen is clamped on the front of the device box, sound amplification ports are opened on the front of the device box and on both sides of the display screen, and an alarm is installed inside the device box and corresponding to the two sound amplification ports.

[0009] Preferably, a single chip microcomputer is installed inside the device box by screws, the display screen is connected to the single chip microcomputer by wires, the two alarms are connected to the single chip microcomputer by wires, and the four magnetic flux current sensors are connected to the single chip microcomputer by wires.

[0010] Preferably, the single chip microcomputer is connected to two indicator lights via wires, both of the two indicator lights are red and green dual-color lamps, and the single chip microcomputer is connected to two lighting lamps via wires.

[0011] Preferably, the rear ends of the two indicator lights are fixedly connected to the slots provided on the corresponding columnar detection rods through injection-molded clamping blocks.

[0012] Preferably, the ends of the two lighting lamps that are away from each other are both mounted on corresponding columnar detection rods by means of screws.

[0016] 1. The utility model symmetrically arranges two columnar detection rods, and emits magnetic waves through the four magnetic flux current sensors on the rods to detect metal objects passing by people. Once ferromagnetic anomalies are found, on the one hand, the indicator light on the corresponding columnar detection rod will be triggered to turn red to remind the location of the ferromagnetic object, reducing the steps of subsequent investigation. On the other hand, the alarm will sound an alarm to remind people that there are metal foreign objects.

On the one hand, it avoids the situation where the detected personnel are injured due to the small spacing between the two columnar detection rods. On the other hand, it avoids the problem of interruption of the magnetic flux signals of the four magnetic flux current sensors due to the long detection distance caused by the large spacing between the two columnar detection rods, thereby improving the accuracy of the detection data.
