Online flood monitoring and alarming system applied to cities

Abstract

The invention discloses an online flood monitoring and alarming system applied to cities. The system comprises a box body and an alarm; a switch button is fixedly connected to the top of the inner side wall of the box body, a sliding rod is fixedly connected to the inner side wall of the box body, a floating ball is slidably connected to the outer side wall of the sliding rod, and a floating plateis fixedly connected to the outer side wall of the floating ball. The outer side wall of the floating plate is fixedly connected with a cleaning plate. According to the system, flood is monitored andalarmed in time through the acting force of water, the inner side wall of the device is cleaned through the buoyancy effect of the water, and the situation that in-time monitoring and controlling ofthe flood by the device is influenced due to the fact that too much dirt exists on the inner side wall of the device is prevented; the outer side wall of the filter screen is cleaned through water flowing, the situation that due to the fact that the filter screen is blocked by dirt in long-term working water of the filter screen, monitoring and alarming are not conducted in time, and the masses are threatened is prevented, resources are greatly saved, and the working efficiency and timeliness of the device are improved.
