Abstract

The invention relates to a shallow-layer transverse wave seismic prospecting epicenter device based on a linear motor; a connecting module is fixed in front of a mount rack module; a linear motor stator is fixed on a recessed surface in front of a vertical plate stator connecting plate of the connecting module; a linear motor mover is fixed on the backside of a mover slide block connecting plate of a weight module; the mover slide block connecting plate is fixed on four linear guide rail slider blocks; the liner guide rail slide blocks are arranged in the front side of two linear guide rails in a slide manner; the two linear guide rails are fixed on projection surfaces on two sides in front of the vertical plate stator connecting plate of the connecting module; the weight is fixed in front of the mover slide block connecting plate; an isolation board is arranged right below the weight; a control box is arranged on the left side of the whole device. The shallow-layer transverse wave seismic prospecting epicenter device can excite standard seismic waves, has large impact speed, can adjust the weight angle according to real landscapes, thus ensuring the impact verticality; the shallow-layer transverse wave seismic prospecting epicenter device is low in noises, high in energy, simple in operation, portable, and economical and practical.

Description

technical field [0001] The invention relates to a seismic source used in the field of shallow shear wave seismic exploration, in particular to a shallow shear wave seismic exploration seismic source device based on a linear motor. Background technique [0002] Seismic exploration uses artificial methods to excite seismic waves (elastic waves), and arranges seismic instruments along the lateral line. According to the different elasticity of various rocks or media that make up the formation, when the seismic wave propagates in the formation, its propagation path, travel time, waveform, The amplitude, etc. will change with the elasticity of the medium and the geometry of the formation interface, and then it is a traditional geophysical method to find out the underground geological conditions. Seismic exploration has a wide range of applications, and has the advantages of high precision, detailed layers, and large detection depth. It plays an important role in the general survey...
