Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flood prevention and control, and in particular to a self-starting flood prevention device. Background Art
[0002] During the flood season every year, due to the continuous increase in rainfall, the river water level will rise sharply over a period of time. Once the river backflows, it will cause flooding. Once the flood is rampant, it will cause damage to houses in towns, flooding of roads, destruction of rice fields, etc., threatening people's property and safety. Therefore, during the flood season every year, water conservancy maintenance personnel will adjust the river water level by controlling the opening and closing of sluice gates according to the rainfall conditions to prevent flooding.
