AUTOMATIC OPERATION DEVICE OF NON-AUTOMATIC OPERATION TYPE ELECTRIC PUMP

PROBLEM TO BE SOLVED: To provide an automatic operation device of a non-automatic operation type electric pump capable of immediately responding to a liquid level, by an automatic operation device of a non-automatic operation type electric pump which eliminates the need for positioning adjustment in detecting a liquid level and is easily handled.SOLUTION: The automatic operation device includes: a detection part 2a which detects a liquid level; a transmitting circuit part which performs a wireless communication 6 of a signal of the detection; and a receiving circuit part receives a detection signal which is performed a wireless communication 6 from a sensor unit 2 which are watertightly disposed a battery housing part. A power opening/closing control unit 3 is equipped with a control circuit part which controls supply and stop of the power to a motor of a non-automatic operation type electric pump 1 based on the received signal. A power cable 1w of the non-automatic operation type electric pump 1 is connected to the power opening/closing control unit 3. The detection sensor unit 2 is put in an area targeted for suction and drainage operation, in contact with liquid. The respective components are separately configured such that the power opening/closing control unit 3 suitably controls the power supply and stop to the non-automatic operation type electric pump 1, based on the detected signal from the detection sensor unit 2.
