An artificial seismic source device for exploration

Abstract

The invention relates to the field of seismic source devices, in particular to an artificial seismic source device for exploration. The seismic source device comprises a base, a first adjusting mechanism, a second adjusting mechanism, a lifting mechanism and a jacking mechanism; the lifting mechanism comprises a lifting assembly and a fixing assembly. The jacking mechanism comprises a jacking assembly, an impact assembly and a clamping assembly. The jacking assembly is arranged at the upper end of the lifting assembly, the impact assembly and the clamping assembly are both installed at the upper end of the jacking assembly; a power distribution cabinet is arranged on the base, four moving wheels are arranged at the lower end of the base, a pushing handle is arranged at one end of the base,a first through opening is formed in the middle of the base, and two gradienters perpendicular to each other are arranged on the second adjusting mechanism. Through adjustment of the first adjustingmechanism and the second adjusting mechanism, the requirement for the flatness of an experimental area can be lowered, the applicability of the device can be improved, through cooperative work of theimpact assembly and the fixing assembly, the kinetic energy of the balancing weight can be controlled and improved, and the applicability of the device is further improved.

Description

technical field [0001] The invention relates to the field of seismic source devices, in particular to an artificial seismic source device for exploration. Background technique [0002] Shallow seismic prospecting technology is one of the fracture survey methods used in shallow surface prospecting in the field. It mainly uses the characteristics of seismic wave propagation in different rocks and soils to detect shallow (usually tens to hundreds of meters) geological structures, determine Engineering geological and geophysical exploration of physical and mechanical parameters of rock and soil. [0003] Chinese patent No. CN201910143246.7 discloses an artificial seismic source device for geophysical exploration, including two No. 1 columns, a middle column and a No. 2 column. The top is provided with a drive box, and the inner wall of the drive box is provided with a telescopic movement mechanism. The outer wall of the center column is provided with a number of fixed holes eve...

AI Technical Summary

Problems solved by technology

Therefore, there are the following insufficient expenditures. First, because the vibration block generates kinetic energy under the action of gravity, the overall equipment needs to reach a certain height to make the kinetic energy of the vibration block large enough. If the overall height of the equipment is too high, it will not only increase the equipment The cost will also increase the finishing weight of the equipment, which is not conducive to field transportation; second, it is not convenient to control the kinetic energy of the vibration block, so it is not convenient to conduct experiments in areas of different nature

Third, there is no adjustment mechanism in the above-mentioned patent, so when in use, the flatness of the experimental site is required to be high, which will increase the labor workload of the experimenters and reduce the efficiency of the experiment
