Suspension system for wideband electrochemical seismometer

Abstract

The invention relates to a suspension system for a wideband electrochemical seismometer, belonging to the field of wideband electrochemical seismometers. The suspension system comprises a diaphragm spring, a vibration pick-up body and a spring bracket, wherein the diaphragm spring is applied to a vertical or horizontal component of the electrochemical seismometer and has different outline structures, and the vertical component diaphragm spring is capable of supplying a gravity supporting force to the vibration pick-up body and guaranteeing the axial flexibility when the radial stiffness is provided; the vibration pick-up body comprises a hollow frame body and a framework tip, the hollow frame coaxially penetrates through an electrochemical measurement unit, and a protruded part on the inner side of the framework tip is connected with the outer surface of a rubber sealing film of the electrochemical measurement unit; and the spring bracket is rigidly fixed at rubber film pressure platesat two ends of the electrochemical measurement unit, and the vibration pick-up body is suspended by virtue of the diaphragm spring and is coaxially aligned with the center of an electrochemical seismometer measurement unit. According to the suspension system, the cross coupling influence among sensitive shafts of the seismometer can be reduced, the long-term stability of parameter indexes can beimproved, and the vibration response consistency of vertical and horizontal components can be improved.
