摘要：NOVELTY - The instrument has a lower clamping sleeve fixed on an inner surface of an organic glass ball (1) in horizontal circumferential direction. A bolt (3) and a supporting frame (7) are connected with a spring (4), where an end of the spring is fixed on an experiment platform (14) of a longitudinal wave electrode plate (6). The longitudinal wave electrode plate is connected with a power supply (12b) that is connected with an indicator light and an alarm (11b). A cathode contact is connected to a lead to perform different longitudinal wave seismic level peak accelerations. USE - Elastic rolling earthquake wave measuring instrument. ADVANTAGE - The instrument has simple structure and reduced power consumption, and is inexpensive. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an elastic rolling earthquake wave measuring instrument.
