Automatic control electric spark source device applied in field of engineering survey and detection

Abstract

The invention discloses an automatic control electric spark source device applied in the field of engineering survey and detection. The automatic control electric spark source device comprises a relay, wherein one end of the output end of the relay is connected with the live wire of an AC 220V power supply, the other end of the output end of the relay is connected with one end of the input end ofan AC transformer; the control end of the relay is connected to a controller through a circuit; the neutral line of the AC 220V power supply is connected to the other end of the input end of the AC transformer; the output end of the AC transformer is connected to the input end of a voltage doubling device; the output end of the voltage doubling device is directly connected to the input end of a high-voltage energy storage capacitor; and the controller controls the on-off state of the relay so as to realize a charging control function of the high-voltage energy storage capacitor. The automaticcontrol electric spark source device can automatically control charging and discharging, can greatly improve the field exploration efficiency, and reduce the labor cost. A synchronous trigger signal can trigger equipment such as a sonic instrument, a seismograph, a TSP instrument and the like, can be used in conjunction with the sonic instrument, the seismograph, the TSP and the like, avoids the idleness of the equipment and enhances the usage rate of the equipment.

Description

technical field [0001] The invention relates to technologies such as AC boosting, half-wave rectification, high-voltage capacitor energy storage, DC high-voltage detection, automatic control, etc., and is mainly used in fields such as engineering survey and detection. Background technique [0002] There are two main types of seismic sources used in engineering: explosive seismic sources and non-explosive seismic sources. The explosion source has good pulse performance and high excitation energy. It has been used since the beginning of elastic wave detection technology. Its disadvantage is that after the explosive is buried on the surface or in the drilling, it will damage the surrounding environment and drilling, and at the same time cause safety hazards. The recovery of the site requires manpower and material resources. In addition, the country’s control over explosives is becoming more and more strict, and the approval process is becoming more and more complicated. Therefo...

According to relevant information, it is found that most of the EDM seismic sources are currently used in marine exploration. Although there are few EDM seismic sources for land exploration, they are relatively heavy, and are not suitable for exploration in areas with inconvenient transportation on land. Occasionally, light ones, but Its performance is lacking; moreover, the sound waves excited by the existing terrestrial electric spark sources generally have weak penetrating ability across holes, and the work efficiency is low
