Problems solved by technology

[0003] Various geophones are used in the current exploration industry, which can be divided into analog, digital, active, passive, single-component or multi-component. The structure of these geophones is very complicated, and some still expensive
One disadvantage of these geophones is that they all need to be manually aligned and coupled with the ground to pick up the seismic reflections generated by the seismic source to explore geological structures

Abstract

The invention discloses an all-terrain geophone shell, which comprises an outer shell, an inner shell, a double-axis swashplate, a geophone core fixing bracket, and a return spring. A The freely rolling positioning steel ball is provided with a locking magnet at the bottom of the fixing bracket of the core body of the geophone. The two-axis swash plate is fixed on the inner casing through the two shafts of its outer ring; one end of the geophone core fixing bracket is fixedly connected to one end of the return spring, and the other end is fixed to the double-axis swashplate. The inner ring of the double shaft swash plate is fixedly connected; the other end of the return spring is fixed on the inner ring of the double shaft swash plate. The present invention is simple in structure and easy to use. Through ingenious structural combination and using few parts, functions such as automatic vertical, automatic locking and automatic unlocking can be realized. and use.

Description

technical field [0001] The invention relates to the field of geophones, in particular to an all-terrain geophone shell. Background technique [0002] Geophones are needed in seismic exploration operations. Geophones are devices that convert ground mechanical vibration signals excited by artificial seismic sources into electrical signals. They are key components for field data acquisition of seismographs. [0003] Various geophones are used in the current exploration industry, which can be divided into analog, digital, active, passive, single-component or multi-component. The structure of these geophones is very complicated, and some Also very expensive. One disadvantage of these geophones is that they all need to be manually aligned and coupled with the ground to pick up the seismic reflections generated by the seismic source to detect geological structures. Contents of the invention [0004] The object of the present invention is to provide an all-terrain geophone shell...
