(2) placing and fixing a submersible pump in the water collecting well, wherein the submersible pump is not contacted with the liquid level detector, the submersible pump is connected with a water pumping belt, and the tail end of the water pumping belt is placed at a water outlet of the submersible pump;
(3) installing searchlights on the wall of the foundation pit, wherein the number, the installation position and the size of the searchlights are based on illuminating all corners of the foundation pit;
(4) installing spherical cameras on the wall of the foundation pit, wherein the number, the installation position and the size are based on observing all corners of the foundation pit;
(5) a control box, a computer and an audible and visual alarm are arranged in a control room, and the logic control mode is as follows: the liquid level detector receives signals and transmits the signals to the control box, the control box can start the submersible pump, the searchlight, the spherical camera and the audible and visual alarm after processing and analysis, after the liquid level detector has no signals, the submersible pump stops working, and the other parts all work normally; after the water leakage accident is processed, manually restoring the system to an initial state;
(6) the floating ball, the floating ball supporting rod, the supporting rod induction head, the guide cylinder and the proximity switch of the liquid level detector are respectively three, the three floating ball supporting rods are different in length, when the water level rises to a certain height, the floating ball connected with the longest floating ball supporting rod rises due to buoyancy, the corresponding supporting rod induction head is close to the corresponding proximity switch, the proximity switch acts and transmits signals to the control box, the control box controls the searchlight and the spherical camera to be turned on through the PLC system, the submersible pump works, the audible and visual alarm acts, a person on duty hears the audible and visual alarm and then turns on the computer, receives the image transmitted by the spherical camera, observes the internal water accumulation condition, searches for a water leakage point and informs related persons to make a solution; if the liquid level rises fast, the floating ball connected with the medium-length floating ball supporting rod rises to trigger the corresponding proximity switch, and the PLC system continues to start the second submersible pump, and so on; after the submersible pump pumps out all the water, the professional enters a pit to treat a water leakage point.
