Abstract

FIELD: applied geophysics. SUBSTANCE: seismic vibrator has actuating mechanism with sensor mounted in it from which signal is sent to automatic controlling amplifier and from the latter - into comparator where it is compared with reference signal from master unit. Isolated disagreement of signals from master unit and sensor is transmitted into hydraulic-volumetric generator. The latter includes two units of cylinders with motors mounted in case for rotation relative to case and driving shaft. Driving shaft carries cams kinematically coupled to cylinders and travelling in cylinders unit. Working chambers of cylinders are connected to main lines with actuating mechanism. Turn of one cylinder unit with reference to the other one leads to change of amplitude of output signal and joint turn of cylinder units relative to case and driving shaft changes vibration phase. Vibration frequency is determined by rotation of driving shaft. Proposed vibrator makes it possible to organize control over frequency, amplitude and phase of seismic vibrator within wide range independent of each other, without use of converters of signal registered by sensor. EFFECT: increased accuracy of control over parameters of seismic vibrator to enhance its efficiency.

Использование: в источниках сейсмических сигналов вибрационного действия в прикладной геофизике. Цель: повышение точности управления гидравлическим вибратором. Сущность: сейсмический вибратор с гидрообъемным генератором колебаний содержит исполнительный механизм с установленным на нем датчиком, сигнал с которого подается на автоматический регулирующий усилитель, а с последнего - в сравнивающее устройство, где он сопоставляется с опорным сигналом с задающего устройства, выделенное несовпадение сигнала с задающего устройства и датчика подается на гидрообъемный генератор колебаний. Последний включает два блока цилиндров с двигателями, размещенными в корпусе с возможностью поворота относительно корпуса и приводного вала. На приводном валу жестко установлены кулачки, кинематически связанные с цилиндрами, перемещающимися в блоке цилиндров, а рабочие камеры последних соединены магистралями с исполнительным механизмом. Поворот одного блока цилиндров относительно другого блока цилиндров приводит к изменению амплитуды выходного сигнала, а совместный поворот блоков цилиндров относительно корпуса и приводного вала изменяет фазу колебаний. Частота колебаний определяется вращением приводного вала. Предлагаемое устройство позволяет организовать независимое друг от друга регулирование частоты, амплитуды и фазы сейсмического вибратора в широком диапазоне, без устройств преобразования сигнала, фиксируемого датчиком.Usage: in the sources of seismic signals of vibrational action in applied geophysics. Purpose: improving the accuracy of control of a hydraulic vibrator. SUBSTANCE: seismic vibrator with a hydrovolume oscillation generator contains an actuator with a sensor installed on it, the signal from which is fed to an automatic control amplifier, and from the latter to a comparison device, where it is compared with a reference signal from the driver, the selected signal mismatch from the driver and the sensor is fed to a hydrostatic oscillator. The latter includes two cylinder blocks with engines placed in the housing with the possibility of rotation relative to the housing and the drive shaft. Cams kinematically connected to cylinders moving in the cylinder block are rigidly mounted on the drive shaft, and the working chambers of the latter are connected by highways to the actuator. The rotation of one cylinder block relative to another cylinder block leads to a change in the amplitude of the output signal, and the joint rotation of the cylinder blocks relative to the housing and the drive shaft changes the phase of the oscillations. The oscillation frequency is determined by the rotation of the drive shaft. The proposed device allows you to organize independent from each other regulation of the frequency, amplitude and phase of the seismic vibrator in a wide range, without signal conversion devices recorded by the sensor.
