Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a seismic geomagnetic detection device. Background Art

[0002] When the earth rotates, a rotating magnetic field is generated. This rotating magnetic field can act on the magma undercurrent to generate an "electromagnetic stirring" force, causing the magma undercurrent to run along with this "electromagnetic stirring force" (similar to the operating principle of an asynchronous motor). During the operation of the magma undercurrent, different undercurrent materials may sometimes be glued together, which is equivalent to a "short circuit" between coils. At this time, underground "lightning" discharges will occur at the "short circuit" site, causing irregular changes in the local magnetic field, resulting in a local loss of gravitational balance in the crust and triggering earthquakes. Irregular changes in the local magnetic field can also lead to the generation of "earthquake clouds" and "earth lights". Therefore, using geomagnetic sensors to measure changes in geomagnetism to predict earthquakes is one of the many ways to predict earthquakes in the prior art. The geomagnetic sensor is made of thin film alloy (permeable magnetic alloy) and measures magnetic field changes based on the basic principle that the resistance characteristics of current-carrying magnetic materials will change when an external magnetic field exists. When the sensor is turned on, assuming there is no external magnetic field, the thin film alloy will have an internal magnetization vector parallel to the direction of the current.

[0003] The existing Chinese patent with announcement number CN214041758U discloses a geomagnetic sensor, which belongs to the technical field of detection equipment, including a shell, a sensing device, a solar panel and a battery. The shell includes a cover body and a base body. The cover body includes a cover plate and a first sleeve connected to the cover plate and arranged circumferentially. The solar panel is installed in the sleeve. The cover plate is arched in an arc shape, and the top surface of the inner cavity of the cover body is provided with grid-shaped reinforcement ribs. The intersection of the reinforcement ribs is provided with threaded holes, and the solar panel is provided with through holes corresponding to the threaded holes, so as to achieve the effect of firmly installing the solar panel and other components.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: there is no alarm measure when the device is stepped on, the protection effect is poor, and the angle of the solar panel cannot be adjusted, which affects the power generation efficiency and needs to be improved; therefore, an earthquake geomagnetic detection device is proposed to address the above problems.
