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.

Description

technical field [0001] The invention relates to the technical field of online flood monitoring, in particular to an online flood monitoring and alarm system applied to cities. Background technique [0002] Flood refers to the flooding and waterlogging of low-lying areas due to heavy rain, heavy rain or continuous rainfall. Rainwater mainly endangers the growth of crops, causes crop production reduction or failure, and disrupts the normal development of agricultural production and other industries. Its impact is comprehensive. It will endanger the safety of human life and property, and affect the long-term stability of the country. From the perspective of the occurrence mechanism of flood disasters, floods have obvious seasonality, regionality and repeatability. For example, the floods in the middle and lower reaches of the Yangtze River in China almost all occur in In summer, the causes are basically the same, but in the Yellow River Basin, there are different characteristic...

Problems solved by technology

[0003] Most of the traditional online flood monitoring and alarm systems are intelligent modularization. Although this method can also monitor floods, this method requires a lot of resources, and most of the traditional flood monitoring and alarm systems cannot be installed correctly. Internal cleaning, which will cause a large amount of dust to accumulate inside the device during long-term use will cause certain failures in the device and affect the timely monitoring and early warning of flood disasters. For this reason, we propose an online flood monitoring and alarm system applied to cities to solve the problem. above question
