Water level monitoring device with alarm function

Abstract

The invention discloses a water level monitoring device with an alarm function, and relates to the technical field of water level monitoring devices. During use, when the water level rises, the first air bag floater and the second air bag floater drive the lifting sliding rod and the mounting plate to move upwards based on buoyancy; when the water level rises rapidly, gas cannot be exhausted in time, the deformation speed of the deformation air bag is not equal to the water level rising speed, at the moment, the upward movement speed of the mounting plate and the upward movement speed of the lifting sliding rod are different, the detection piece and the protruding block are matched, and the difference is detected; the water level rising condition can be judged conveniently; due to the fact that the multiple vertically-distributed installation bags are installed on the connecting rod, the more the installation bags are immersed when the water level rises, the corresponding buoyancy is increased accordingly, if the protruding block can still move upwards in the detection channel, it is indicated that the water level rising speed is high, and when the set protruding block reaches the set detection piece, the alarm mechanism conducts alarm processing.
