Abstract

The invention discloses an automatic seismograph leveling and locking device and relates to the technical field of marine seismic observation. The automatic seismograph leveling and locking device comprises a sensor, a leveling mechanism, two groups of locking mechanisms and a control component, wherein the sensor is arranged on the top of a seismograph and is used for detecting whether the seismograph is horizontal or not; the leveling mechanism comprises an outer balance ring, an inner balance ring and a clamping ring; the seismograph is fixed in the clamping ring; a center of gravity of the seismograph is lower than a horizontal plane where the clamping ring is positioned, the clamping ring is pivoted inside the inner balance ring, and the inner balance ring is pivoted inside the outer balance ring; the two groups of locking mechanisms are respectively used for locking relative positions of the clamping ring and the inner balance ring and relative positions of the inner balance ring and the outer balance ring; the control component is electrically connected with the sensor and the two groups of locking mechanisms and is used for receiving detection results from the sensor and sending operation instructions to the two groups of locking mechanism. The invention provides the automatic seismograph leveling and locking device which is used for solving a problem that an automatic leveling and locking function cannot be fulfilled by a seabed seismograph.

Description

technical field [0001] The invention relates to the technical field of marine seismic observation, in particular to an automatic leveling and locking device for a seismograph. Background technique [0002] The frequency band of natural seismic waves is very wide. According to the different frequency bands of seismic observation, seismographs are divided into short-period seismographs, broadband seismographs, and very wide-band seismographs. Seismographs of different frequency bands are also required for submarine seismic observation. Earthquakes that occur under the sea. [0003] Broadband seismographs are widely used in research fields such as crustal movement, resource exploration and development, internal structure imaging of the earth, and monitoring of seabed dynamic processes. Seismographs are high-precision instruments that are sensitive to orientation, especially in the vertical direction. When the seismograph is in a tilted state and exceeds the limit range allowed...
