Hydropower station water level alarm device and use method thereof

Abstract

The present invention discloses a hydropower station water level alarm device which comprises a base with a fixing hole, a vertical height adjusting mechanism, a horizontal length stretching mechanism and a monitoring mechanism used for monitoring the water level, the vertical height adjusting mechanism is installed at the upper end of the base, the horizontal length stretching mechanism is connected with a lifting component of the vertical height adjusting mechanism, and the monitoring mechanism is connected with a horizontal moving part of the horizontal length stretching mechanism; and the vertical height adjusting mechanism comprises a screw rod, a stand column, a supporting plate and a threaded sleeve. The height positions of the first abutting piece and the second abutting piece can be adjusted according to the actual water level of a river, so that the alarm threshold values of the highest water level and the lowest water level are limited, meanwhile, alarming is conducted in the high water level dangerous state and the low water level dangerous state, the situation that the water level is lower than the lowest water level in the water drainage process can be avoided, and the device is simple in structure, and high in flexibility, and the installation position of the water level alarm device for the hydropower station can be moved according to actual conditions, so that the self-operation cost is saved.

Description

technical field [0001] The invention belongs to the technical field of water level alarms for hydropower stations, and in particular relates to a water level alarm device for hydropower stations; the invention also designs a method for using the water level alarm device for hydropower stations. Background technique [0002] The safety of hydropower stations is very important. It is not only related to the electricity consumption for production and life, but also to the personal safety of people downstream. Therefore, the safety of hydropower stations has always been a hot spot of concern, and the water level of hydropower stations is an important factor affecting the safety of hydropower stations. Factors, because the water level is too high, or the arrival of the flood peak may cause safety problems of the dam, so it is necessary to monitor the upstream water level and water flow at all times. [0003] In the prior art, the water level monitoring device of the hydropower st...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a water level alarm device for a hydropower station to solve the problem that the monitoring components cannot monitor the actual water level due to the leakage of the river bed in the summer when the river water dries up in the prior art mentioned in the background art
