A device for cleaning water wells comprises a downhole apparatus, which consists of an electrohydraulic unit (7) with a resonant circuit and an ultrasonic unit (4) with an electroacoustic transducer (3) arranged consecutively in a single housing, sensors of pressure (10) and flow (11), a hydrophone (12), a pump, an ultrasonic generator (13), a pulse generator (14), sensor monitoring equipment (15), and a downhole apparatus control unit (16) provided with a synchronizer for synchronizing the operation of the electrohydraulic unit (7) and the ultrasonic unit (4), and also with a device for controlling pulse duration, beating frequency and the signal spectrum of the resonant circuit of the electrohydraulic unit in order to alter the area of action. Furthermore, a discharge chamber (8) and a protective cap (9) are situated in the bottom part of the downhole apparatus. |
