[0008] As a further improvement to the above solution, angle plates are symmetrically arranged between the lower end of the back surface of the panel and the upper surface of the base plate seat to strengthen the strength of the panel and avoid changes in the angle between the panel and the base plate seat.

[0009] As a further improvement to the above solution, an L-shaped scale plate is fitted under the base plate, and the scale line is a safety line for expressing a safe water level.

[0010] As a further improvement to the above solution, warning scale lines are symmetrically arranged on both sides of the front side of the panel.

[0011] Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, novel and unique concept, by floating the float on the water surface, utilizing the rising water level and the buoyancy of the float on the water surface to push the hollow tube upward, the guide bar is displaced in the waist hole, and the pointers on both sides of the guide bar will be displaced on the scale line to indicate the water level; in addition, the guide bar is displaced in the waist hole, and the slider integrally connected to the guide bar is displaced in the box body, ensuring that the guide bar is displaced smoothly with the slider to prevent jamming, and at the same time the scale of the L-shaped scale plate indicates the safe water level.
