the control processor (2) outputs a clamping signal to the clamping device (39).
9. Method of operating a sampling device for sampling liquids at different depths as in claim 7, characterized in that the adjustment means (38) adjust the position of the aspirator (37) to the corresponding operating position comprises the following steps:
the adjusting device (38) receives the adjusting signal;
the recovery device (382) releases the connection tube, which is extended with the displacement of the sampling tube (32).
10. A method of operating a sampling device for sampling liquids at different depths as set forth in claim 7, comprising the steps of:
if the capacity detection device (4) detects that the smelting of the sampling tube (32) reaches a preset capacity threshold value, the capacity detection device (4) outputs a capacity signal to the control processor (2);
the control processor (2) outputs a stop signal to the aspirator (37) corresponding to the sampling tube (32);
the suction unit (37) stops suction;
if the distance value monitored by the distance sensor (5) is larger than a preset distance value threshold value, the distance sensor (5) outputs a closing signal to the control processor (2);
the control processor (2) restarts all the attractors (37) and shuts down the restarted attractors (37) within a preset time.
