An artificial seismic source device for geophysical exploration

Abstract

The invention discloses an artificial seismic source device for geophysical exploration. The artificial seismic source device comprises two standing columns I, middle columns, and standing columns II.A bottom box is arranged at the bottoms of the standing columns I; a drive box is arranged at the top of the bottom box; and a telescopic moving mechanism is arranged at the inner wall of the drive box. A plurality of fixing holes distributed uniformly at equal intervals are formed in the outer walls of the middle columns. The middle columns are fixed at the inner tops of the standing columns I and the inner bottoms of the standing columns II by fastening bolts I; and one same top plate is arrange at the tops of the two standing columns II. A power supply mechanism is arranged at the top of the top plate; two fixed frames are arranged at the bottom of the top plate; and same directional wheels are arranged at opposite sides of the two fixed frames. According to the invention, on the basisof an electric hydraulic push rod driving mode, the height of the universal wheel is adjusted freely, the ground gripping effect of the device is improved; the light energy utilization rate is increased; the effects of energy conservation and environment protection are realized; and the wearing of the metal-structure hanging ring is avoided.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration, in particular to an artificial seismic source device for geophysical exploration. Background technique [0002] At present, shallow seismic exploration technology is used as one of the methods of fracture exploration in the existing field shallow geophysical exploration.
