Road water level monitoring and alarming device

Abstract

This invention discloses a road flooding level monitoring and alarm device, belonging to the field of water level monitoring, comprising a base, a cone, a transparent light-emitting tube, and a water level indicator tube. The base has multiple fixing feet evenly distributed around its bottom perimeter and a through hole in its center. Multiple guide holes are formed in the base, each containing a sliding adjustment tube driven by a screw-driven adjustment knob. A radially sliding stop is located at the bottom to accommodate the installation of drainage grates. The cone is fixed to the base and communicates with the through hole. The transparent light-emitting tube is coaxially mounted inside the cone and can slide up and down, with a first floating airbag in its center. The water level indicator tube, red in color, is slidably mounted inside the transparent light-emitting tube and has a float at its bottom. A first limiting component is located at the top of the cone to restrict the transparent light-emitting tube from floating upwards; a driving component is located on the base to drive the stop to slide. When the floodwater level rises, the float moves the water level indicator tube upwards, while the transparent light-emitting tube floats with the floating airbag, visually indicating the water level and thus providing an alarm function.
