[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Figure 1 This is a structural diagram of one embodiment of a high-coupling, high-induction, high-precision seismograph seismic signal detection needle device of this utility model, as shown below. Figure 1 As shown, this embodiment includes:
[0026] 1. Probe needle; 2. Sensor module; 3. Signal amplification and processing module; 5. Adjustment support structure; and 4. Data transmission and storage module.
[0027] The probe 1 is connected to the sensor module 2. The probe 1 is mounted on the adjustment support structure 5. The sensor module 2 is electrically connected to the signal amplification and processing module 3. The signal amplification and processing module 3 is electrically connected to the data transmission and storage module 4.
[0028] It is understood that this embodiment includes a probe 1, a sensor module 2, a signal amplification and processing module 3, an adjustment support structure 5, and a data transmission and storage module 4.

The sensor module 2 and the signal amplification and processing module 3 are electrically connected, and the signal amplification and processing module 3 and the data transmission and storage module 4 are electrically connected. This can effectively improve the coupling effect between the seismograph and the ground surface, improve the sensitivity and accuracy of earthquake signal detection, and thus achieve accurate detection of weak seismic waves and teleseismic signals, as well as weak ground vibration signals in urban areas.
[0029] It should be noted that the adjusting support structure 5 has an automatic leveling system that automatically adjusts the length of each support structure to ensure that the seismograph's base remains level, thus preventing data distortion due to ground tilt. An automatic stabilization system adapts to ground vibrations or uneven settlement, reducing external environmental interference with the seismograph. The automatic leveling system includes a controller and an inclination sensor. The controller adjusts the length of each support structure based on the inclination sensor signal to ensure the seismograph's base remains level.

This module is designed with an adaptive coupling system, dynamically adjusting the sensor's response characteristics to adapt to variations in the frequency and intensity of different seismic waves, thereby improving detection accuracy. It is integrated with the probe 1, and its base is weight-adjustable to increase stability.
[0037] Through mechanical structure optimization, probe 1 is directly coupled to piezoelectric, inductive, and fiber optic sensors. Vibrations from probe 1 are transmitted to the sensor interior via rigid or flexible connections, reducing energy loss. Flexible connections utilize elastic materials for vibration matching, preventing attenuation of high-frequency signals.

This module employs a multi-stage amplification circuit design to effectively reduce signal noise and remove environmental interference through filtering technology. The amplified signal is then transmitted to the signal processing unit for further digital processing and feature extraction.

[0046] In some optional embodiments, the base is made of high-strength material and fixed to the ground surface to ensure the stability of the device during seismic signal detection. The probe 1 is made of highly conductive material, with one end fixed to the base and the other end in direct contact with the ground surface to conduct seismic signals.
