Description

Technical Field

[0001] The utility model relates to the technical field of seismic geophone sensors, in particular to a geophysical exploration seismic geophone sensor. Background Technique

[0002] In the prior art, seismic geophone sensors are widely used in geological exploration and detection in industries such as coal and geology. The structural principle of the seismic geophone sensor is that a resonance system composed of a pair of spring sheets and coils with relatively strong anti-lateral interference ability is arranged in the geophone core body. This resonance system is placed in the working air gap of the magnetic circuit composed of the cylindrical permanent magnetic shell of the geophone and the magnetic steel, magnetic yoke, etc. placed in the center. When the ground vibrates, the geophone shell fixed to the ground moves accordingly, and the coil in the geophone also makes reciprocating vibrations up and down in the working air gap of the magnetic circuit.

[0003] After retrieval, a patent with the Chinese patent application number 202322447916.9 discloses a geophysical exploration seismic geophone sensor, including a sensor and an anti-shock structure, and the anti-shock structure is arranged on the surface of the sensor; the anti-shock structure includes a support ring sleeved on the surface of the sensor shell, and the anti-shock structure also includes a plurality of evenly distributed transmission rods hinged to the top of the sensor base and the surface of the support ring. A working sleeve is sleeved on the surface of two opposite transmission rods. Sliding holes are opened on both sides of the working sleeve. The transmission rod extends into the interior of the working sleeve through the sliding hole. One end of the transmission rod located inside the working sleeve is fixedly connected with a driving plate, and a plurality of evenly distributed flow holes are opened on the surface of the driving plate.

[0004] The above patent has the following deficiencies: This device quickly slows down, absorbs, and resists shocks through the principle of damping effect and magnetic force repulsion of like poles, and then can cause the sensor to quickly reset; in field acquisition, it is inevitable that there will be times when the geophone is used as a shock source trigger. A simple method is to connect the geophone to the instrument vehicle and place it close to the shock source position. When the shock source is triggered, the geophone close to the shock source receives the signal first, thereby triggering the instrument to receive the shock source signal to form a acquisition record. However, the above seismic geophone sensor has relatively low accuracy and is not conducive to rapid use. Content of the Utility Model
