Description

Technical Field

[0001] The utility model relates to the technical field of waterlogging monitoring and early warning, and in particular to a waterlogging monitoring and early warning device for urban waterlogging points. Background Art

[0002] High rainfall intensity and concentrated range are the direct causes of urban waterlogging. Especially sudden rainfall and long-term, high-intensity rainfall can easily cause water accumulation. These accumulated waters cannot be discharged in time through the city’s sewer network, thus causing urban waterlogging.

[0003] In order to obtain urban waterlogging information in a timely manner, it is necessary to conduct real-time monitoring of waterlogging points. Usually, the monitoring location is the sewer of the drainage network. The existing monitoring system actually sets a water level monitor in the sewer, and judges the information of urban waterlogging through the data fed back by the water level monitor. However, since the water level monitor is set in the sewer, the sewer is responsible for the drainage of the city, which makes the water level sensor easily affected by debris. The actual use effect is very poor and there are certain shortcomings. For this reason, we propose a waterlogging monitoring and early warning device for urban waterlogging points.
