Culvert water level warning device

Abstract

The invention discloses a culvert water level warning device. The device comprises a sensor, wherein the sensor is mounted in a culvert, and the sensor is used for always detecting a water level in the culvert to be used as input signals to be sent to a railing control circuit; when the water level in the culvert is detected by the sensor to reach a danger value, a motor is controlled by the railing control circuit to drive an automatic railing to be automatically put down, and pedestrians and vehicles are forbidden to pass. For the culvert water level warning device disclosed by the invention, when the water level in the culvert reaches the danger value, the automatic railing can be automatically controlled to be put down, so that the pedestrians and the vehicles are forbidden to pass, and the ultimate goal of the water level warning device is achieved.

Description

technical field [0001] The invention relates to the technical field of electronic instruments and sensors, in particular to a water level warning device for culverts. Background technique [0002] At present, there are frequent incidents of culverts being flooded and causing casualties; although there are warning signs at the culvert entrance, the signs are not eye-catching and cannot dynamically indicate the water level in the culvert. Passage, or with a fluke mentality, it is too late when irreparable losses are caused; some water management departments require special personnel to go to the scene to maintain order during heavy rains, which increases administrative costs and violates the scientific and efficient urban management. Concept, for this reason, we have developed a culvert water level warning device with a buzzer alarm and automatic lowering of the railings when the water level reaches a dangerous value, thus protecting the lives and property of the people and im...
