A scale plate 6 is fixedly connected to the middle of the bottom side of the upper part of the bracket body 1. A groove 301 is provided on the scale plate 6, and the scale plate 6 is movably connected within the groove 301. A threaded knob 302 is fixedly connected to the upper surface of the groove 301. The lifting mechanism 2 includes a fixed box 201, a gear 202, a limiting plate 203, a spring 204, a lifting column 205, a rotating rod 206, and an iron ring 208.

The solar panel 4 is electrically connected to the infrared sensor to power the infrared alarm 3. The water level is limited by the scale plate 6. The water level warning is achieved by setting the distance of the slide 301 on the scale plate 6. When the water level rises, the float 8 rises due to the design of the through hole 803 in the center of the float 8. When the infrared alarm 3 detects the float 8, it will sound an alarm.
