FIELD: electricity.SUBSTANCE: pulse non-explosive seismic vibrator with an electromagnetic drive includes a stiff plate emitting seismic waves, a balance weight, dampers, an electrical power supply system consisting of a charging device and a capacitor battery, and an electromechanical converter. An emitter is made in the form of a hollow box with a flat bottom. Inside the box there arranged in the centre is a balance weight of variable mass, and on both sides of the balance weight there arranged is a charging device and a capacitor battery. The electromechanical converter is made in the form of a short-stroke pulse electric motor consisting of an armature and an inductor, which represents an integral part of the balance weight. The inductor has slots on the side facing to the armature, in which an excitation coil is arranged. Between the armature and the inductor there are arranged plates with a possibility of controlling a working gap between the armature and the inductor, the charging device with the capacitor battery is connected via a power cable to the excitation coil.EFFECT: higher operating efficiency of a seismic vibrator.4 cl, 1 dwg |
