Dam automatic safety protective device

Abstract

A dam automatic protection safety device belongs to the field of water conservancy safety protection. A flood discharge pipe is fixed on the fixed seat, a dike protection switch is set on the upper part of the flood discharge pipe, and the dike protection switch and the flood discharge pipe are directly sealed or sealed The water discharged from the flood discharge pipe is directly sent out of the dam or sent out of the dam through the outlet pipe or sent out of the dam through the channel. The dam protection switch can move up and down on the upper part of the spill pipe, and can open or close the spill channel when moving up and down. The dam automatic protection safety device has a compact and reasonable structure, is convenient to manufacture and use, has a strong ability to protect the safety of the reservoir, and has a high degree of automation. choose.

Description

technical field [0001] The invention relates to an automatic protection safety device for dams in the field of safety protection and management of reservoir dams. Background technique [0002] The flood discharge of present reservoirs basically all adopts overflow flood discharge, and its method is: offer a flood discharge channel on the embankment, perhaps, offer a flood discharge inlet hole on the embankment. Open the flood channel on the embankment, because the flood channel is opened on the embankment, the stress uniformity of the dam body of the embankment is affected, causing the embankment to be easily washed away by the flood in the flood season. Open the flood discharge inlet hole on the embankment, because there are floating objects in the flood, the floating object in the flood causes the flood discharge inlet hole to be blocked, and then causes the flood to cross the embankment. In addition, the dams of general reservoirs basically use stone dams, and the fillin...

AI Technical Summary

Problems solved by technology

In addition, the dams of general reservoirs basically use stone dams, and the fillings in the dams are soil; especially in summer, the dams of the reservoir become dry and loose after being exposed to the sun. , the heavy rain makes the water level of the reservoir rise sharply, and it is easy to wash away the part of the dam above the normal water level that has been dried and loosened by the sun

In addition, when there is a heavy rain, the mountain torrents also erupt, causing the reservoir's flood channel to be unable to drain the torrential rain and torrents in the reservoir in time, which in turn causes the water level in the reservoir to rise sharply, causing the torrential rain and torrents to overturn from the dam. when the dams of the reservoirs are overturned by heavy rains and mountain floods, the dams are easily washed away, causing floods
