Earthquake displacement recording device

Abstract

The invention relates to the technical field of earthquake monitoring, specifically to an earthquake displacement recording device. The device comprises a device body; the device body comprises an upper measuring rod, a lower measuring rod and a recording plate; the upper measuring rod is upwards connected with an upper mounting foundation and downwards connected with the lower measuring rod; thelower measuring rod is downwards connected with a probe; the tip of the probe is downwards in contact with the recording plate; and the recording plate is connected with the lower mounting foundation;the lower measuring rod is provided with a first inner cavity with a downward opening; a spring is arranged in the first inner cavity; and the upper end of the probe extends into the first inner cavity and contacts with the spring. The device is simple in structure and easy to manufacture, popularize and use; due to the fact that the device body is of a pure mechanical structure, the hidden danger of instability caused by a traditional electronic and mechanical combined structure with a sensor as a detection element is eliminated, the working stability is good, the service life is long, and the real-time performance is good.

Description

technical field [0001] The invention relates to the technical field of seismic monitoring, in particular to a seismic displacement recording device. Background technique [0002] Seismic monitoring refers to the monitoring and measurement of earthquake precursor anomalies and seismic activity before and after an earthquake. Generally, monitoring instruments, such as water level gauges, seismographs, and electromagnetic wave measuring instruments, are used to monitor the microscopic precursor information of earthquakes. Traditional earthquake monitoring devices or equipment are generally equipped with displacement or acceleration sensors to measure and capture relevant information. Conventional displacement sensors are rod-shaped structures that can only measure and capture displacement data in one direction, while data in other directions are basically It cannot be obtained, and its setting needs to be perpendicular to the measurement direction and cannot be moved, but the ...

Traditional earthquake monitoring devices or equipment are generally equipped with displacement or acceleration sensors to measure and capture relevant information. Conventional displacement sensors are rod-shaped structures that can only measure and capture displacement data in one direction, while data in other directions are basically It cannot be obtained, and its setting needs to be perpendicular to the measurement direction, and it cannot be moved, but the direction of earthquake occurrence is basically unpredictable, so the application of this type of sensing device is limited
