Description
Technical Field
The utility model relates to a seismograph technical field particularly relates to a power supply unit and adjustable terminal group for field exploration seismic apparatus.
Background
Seismic instruments are electronic instruments used in modern exploration techniques to record vibrations, the vibrations recorded by which exhibit a curve with different relief amplitudes, called the seismic spectrum. The amplitude of the curve corresponds to the amplitude of the ground vibrations caused by the seismic waves, so that the effects of various types of seismic waves are generally determined and identified from the seismic spectrum.
Seismic instruments currently in use, such as the us ES-2420 digital seismometer, are not equipped with a built-in power supply, and need to be driven by an external power supply alone. The instrument consumes more electricity when working, the current of the whole machine reaches about 45A, and the instant impact current of the starting-up reaches more than 50A. When the instrument works in the field, the power is continuously supplied through a large-capacity storage battery. In addition, for example, R24 shallow seismographs, which use 12VDC as the input power, also need to carry power separately while working in the field to ensure continuous operation of the instrument.
Therefore, in actual exploration and exploration work, different seismographs need to be independently provided with power supplies with different outputs, and the power supplies are large-capacity battery jars, are large in weight and size and are inconvenient to carry.
