Unusual seismic detection system of portable urban geology

The utility model relates to an unusual seismic detection system of portable urban geology, including seismic signal receiving arrangement, its adoption is conjuncted through the linear mobilizable sensor level that many connecting rods shock insulation leg joint constitutes by a plurality of roller type seismic sensor, sets up the wave detector core in the roller bearing of roller type seismic sensor, installs wireless earthquake on many connecting rods shock insulation support respectively and gathers basic station and outer trigger device, and the seismic source device sets up the side at many connecting rods shock insulation support, the seismic source device is connected with outer trigger device, wireless earthquake is gathered the basic station and is connected with wave detector core, outer trigger device respectively. The utility model is suitable for a city is unusual detection within 50 meters and geology diagnosis secretly. Because the wave detector core is fixed in and rolls axletree part, realiz
