The invention discloses online detection equipment for a liquid in a
sewage pool, wherein the online detection equipment comprises the
sewage pool, and a mounting plate is arranged at the bottom end in the
sewage pool. According to the online detection equipment, through cooperative use of a floating plate, a detection rod, a first limiting rod, a second limiting rod, a sliding sleeve, a first transverse plate, a second transverse plate, a third transverse plate, an
inductor, a rubber pad and an alarm, online detection of the liquid in the sewage pool is facilitated, and the phenomenon of idle running of a pump body is prevented; when the liquid level in the sewage tank is low, the floating plate can drive the detection rod to move downwards, so that the rubber pad at the bottom end of the third transverse plate on the surface of the detection rod is in contact with the
inductor at the top of the first transverse plate, then the
inductor transmits a
signal to a control panel, the control panel stops working of the pump body, and then an alarm is controlled to sound to play a warning role; and by means of the mode, the liquid level in the sewage pool can be effectively detected on line, and the phenomenon of idle running of the pump body is prevented.
