Flood prevention early warning device for reservoir

Abstract

The invention relates to the field of flood prevention early warning, in particular to a flood prevention early warning device for a reservoir, which comprises a fixed pipe. Mounting blocks are arranged on the outer surfaces of the two ends of the fixed pipe, a base station is arranged at the upper end of the fixed pipe, a driving mechanism is arranged in the fixed pipe, a moving mechanism is arranged at one end of the driving mechanism, a trigger mechanism is arranged at one end of the base station, the driving mechanism comprises a sliding groove formed in the inner wall of the fixed pipe, a floating block is arranged on the inner side of the fixed pipe, limiting blocks are connected to the outer surfaces of the front end and the rear end of the floating block, a rack is arranged on the inner side of the sliding groove in the upper ends of the limiting blocks, a fixing frame is connected to the upper end of the base station, and a gear is connected between the rack and the fixing frame. According to the flood prevention early warning device for the reservoir, a flood prevention alarm system can be started along with the change of the water level of a dam, and the whole device is full-automatic, not prone to being affected by stormy waves, high in stability and sensitive.

Description

technical field [0001] The invention relates to the technical field of flood control and early warning, in particular to a flood control and early warning device for reservoirs. Background technique [0002] Reservoirs are generally interpreted as "hydraulic engineering structures that hold back flood water and regulate water flow, and can be used for irrigation, power generation, flood control and fish farming." It refers to artificial lakes formed by building dams at the narrow mouths of ravines or rivers . After the reservoir is completed, it can play the roles of flood control, water storage for irrigation, water supply, power generation, and fish farming. Sometimes natural lakes are also called reservoirs (natural reservoirs). The size of the reservoir is usually divided into small, medium, and large according to the size of the storage capacity. In some southern regions, if there is continuous heavy rain, the water level of the reservoir may increase suddenly, which ...

AI Technical Summary

Problems solved by technology

[0003] The traditional flood control early warning device for reservoirs has some shortcomings. The flood control early warning device is greatly affected by the waves on the water surface. When the wind is strong, even if the water level does not reach the alarm level, the flood control alarm device may be triggered, which is not stable enough and has a wide range of applications. narrow
