Hydraulic dam water level early warning device

Abstract

The invention discloses a hydraulic dam water level early warning device which is characterized in that an early warning mechanism comprises a stand column, an alarm is fixedly connected to the top of the stand column, a lifting groove is formed in the outer surface of the stand column, a rotating groove is formed in the outer surface of the stand column, and a screw rod is rotationally connected into the lifting groove. The invention relates to the technical field of a hydraulic dam. According to the hydraulic dam water level early warning device, by arranging the early warning mechanism, when the water level stably rises and reaches the early warning water level, a connecting sleeve makes contact with a connecting rod, so that an alarm circuit is switched on for early warning; and then when the water level rapidly rises, the screw rod drives a rotating plate to increase the rotating speed, so that the contact frequency of the rotating plate and a contact plate is increased; and when the contact frequency reaches the preset frequency, the alarm performs water level early warning so as to timely discharge the dam and discharge the flood. Through the combination of the structures, the problems that the flood spreads and the hydraulic system of the hydraulic dam is damaged easily due to the fact that the water level rapidly rises when the existing flood season comes are solved.

Description

Technical field [0001] The present invention relates to the technical field of hydraulic dams, in particular a hydraulic dam water level early warning device. Background technique [0002] Hydraulic concrete lift dam is a relatively simple activity dam technology in water conservancy technology. It is widely used in agricultural irrigation, fisheries, ship locks, sea water, urban river landscape engineering and small water power station, etc., hydraulic lifting dam mechanical structure, no water Not afraid of mud silt; not affected by floating objects; can easily rush away from the float of upstream, so that the river is clear; the dam is fast, does not affect flood protection; strong ability to impact floods It overcome the shortcomings of traditional event dam types, but it also has all the advantages of traditional dam type: it is like rubber dams in the river bed without water (better than the rubber dam); Dam row, any water level height; it is rugged like a water gate.

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a hydraulic dam water level early warning device, which solves the existing problem that the rapid rise of the water level when the flood season comes easily causes the flood to spread and the hydraulic system of the hydraulic dam is damaged.
