UNIVERSAL NON-EXPLOSIVE PULSED ELECTRODYNAMIC SEISMIC VIBRATOR FOR TRANSIT ZONES Russian patent published in 2020 - IPC G01V1/02 

FIELD: device for generation of seismic energy.

SUBSTANCE: invention relates to devices for generation of seismic energy. Device comprises sealed housing (11) with bottom made from steel, made with possibility of arrangement of suspended float system. Inside housing (11) there is rigid plate-emitter (1) of seismic waves. On upper surface of emitting plate (1) there are first excitation coils (2) made in form of copper spiral. On plate-emitter (1) there are insulating plates (3), in groove on lower surface of which there are adjacent to first excitation coils (2) second excitation coils (4). Outputs of second excitation coils (4) are connected to unit (5) of storage capacitors and their charging device, as well as to electronic control cabinet. On each insulating plate (3) there is balance weight (6) with linear bearing (7), which is made with possibility of movement along guide tube (8) installed on plate-emitter (1). Inside guide tube (8) there is damper (9).

EFFECT: high reliability of the seismic vibrator during operation in difficult climatic conditions and broader capabilities of performing seismic operations.
