The invention provides an acceleration seismic source excitation device based on SH transverse waves, and relates to the technical field of underground space exploration devices. The acceleration seismic source excitation device comprises a rack, a chopping board, a nitrogen spring, a heavy hammer, a heavy hammer locking mechanism and a heavy hammer lifting mechanism. The rack is of a hollow structure with an opening in the lower end. The chopping board is arranged at the bottom of the rack; the heavy hammer is movably arranged in the rack and used for impacting the chopping board; the nitrogen spring is arranged in the rack and located at the upper end of the rack. The nitrogen spring is used for accelerating the heavy hammer; the heavy hammer lifting mechanism is arranged on the outer side of the rack and is used for lifting the heavy hammer to an upper limit position, so that the heavy hammer extrudes the nitrogen spring to a compressed state; the heavy hammer locking mechanism is arranged on the outer side of the rack and used for locking or releasing the heavy hammer at the upper limit position; the counter weight can generate large acceleration under the action of the nitrogen spring, the chopping board is impacted by large impact force, and the device has the advantages of being large in detection depth and high in resolution ratio.
Description
technical field [0001] The invention relates to the technical field of underground space exploration devices, in particular to an acceleration seismic source excitation device based on SH shear waves. Background technique [0002] Seismic exploration sources are divided into explosive sources and non-explosive sources. Wherein the explosive source is an explosive source. Non-explosive sources can be divided into vibrators and impact sources. The vibrator includes: electric spark vibrator, electromagnetic vibrator, hydraulic vibrator, etc. The impact type vibrator includes: artificial hammer vibrator, falling weight hammer vibrator, impact rammer vibrator, acceleration hammer vibrator. [0003] The acceleration weight source is gradually improved and developed from the early drop weight source. The current acceleration weight vibration source is to reduce the weight and lifting height of the weight of the falling weight vibration source, and increase its excitation speed t...
