VIBRATION PULSE SOURCE OF SEISMIC SIGNALS Russian patent published in 2001 - IPC

FIELD: generation of seismic waves by dynamic loading of ground space. SUBSTANCE: vibration pulse source includes weight located in body, rests to fix weight in initial position, system controlling rests coupled to hydraulic control system, emitting plate and mobile mass on springy tubular members deformed in advance and coupled to oscillator. Mobile mass carries hydraulic cylinder-pusher coupled to hydraulic-pneumatic accumulator used to return weight to initial position. EFFECT: increased dynamic action of ground space and reduced energy consumption to rest source for excitation of next pulse. 1 dwg
