[0013] (III) Beneficial effects

[0014] The utility model provides a sewage well pH detection device with an alarm function. It has the following beneficial effects:

[0015] (1) A sewage well pH detection device with an alarm function. It can be concluded from the above that, when the sewage water level in the sewage well body gradually rises, the buoyancy of the water exerts an upward force on the float and the float rod, and the float and the float rod push the movable plate, the sealing ring, the first copper sheet, and the slide rod to slide upward. The spring is compressed and deformed to generate elastic force. When the movable plate drives the first copper sheet to move upward until it contacts the second copper sheet, the circuit is closed, and the controller controls the warning light to start. The warning light flashes brightly to give a high water level alarm. After the sewage is discharged from the sewage well body, the elastic force of the spring pushes the movable plate, the first copper sheet, and the detection probe to descend. The first copper sheet is no longer in contact with the second copper sheet, the circuit is disconnected, and the warning light no longer gives an alarm. The sealing ring slides with the inner wall of the box body to prevent sewage from entering the upper part of the movable plate in the box body. The detection probe contacts the sewage, and the pH detection value is converted into an electrical signal and transmitted to the pH detector. The pH value of the sewage can be read at any time by the pH detector, so as to record the pH of the sewage.

[0016] (2) This sewage well pH detection device with an alarm function is capable of manually detecting the high water level alarm function by periodically pulling the pull rope upwards. The pull rope drives the sliding rod, the movable plate, the first copper sheet, the floating rod and the floating ball to move upwards, so that the first copper sheet contacts the second copper sheet, the circuit is connected, and the warning light sounds an alarm. This prevents the high water level alarm function from malfunctioning. BRIEF DESCRIPTION OF THE DRAWINGS
