Siphonic weir capable of controlling water level automatically

Abstract

The invention discloses a siphonic weir capable of controlling a water level automatically. The siphonic weir comprises a barrage for intercepting water flow and forming an upstream riverway and a downstream riverway and a water pipe arranged on the barrage. The water pipe penetrates through the barrage. The water pipe comprises an upstream pipe body and a downstream pipe body. The upstream pipe body is provided with a water inlet arranged at the upstream riverway, and the downstream pipe body is provided with a water outlet arranged at the downstream riverway. The water pipe is provided with a top end, the height of the top end relative to the bottom of the barrage is larger than that of any position of the water pipe relative to the bottom of the barrage, and the top end is higher than the water inlet and lower than a water overflowing position of the barrage. The water inlet is higher than the water outlet. The siphonic weir can control the river water level automatically, discharge flood automatically and reduce river management cost.

Description

technical field [0001] The invention relates to the field of water conservancy and fluid control engineering, in particular to a siphon type automatic control water level weir. Background technique [0002] Landscape rivers or inland rivers in the city need to be intercepted and stored in the dry season. The river after storage can beautify the city environment and adjust the urban humidity; while in the wet season, it is necessary to open the gate to release water to prevent Waterlogging. The control of the river water level is generally done by arranging staff to work on the dam, but this increases labor and management costs, and is not safe for those who often work on the dam. [0003] Therefore, it is very necessary to provide a weir gate that can effectively realize automatic water level control. However, the current problem of water level control barrages is that the drainage gate and its control device rely on external energy such as electricity in the process of op...

AI Technical Summary

Problems solved by technology

However, the current problem of controlling water level barrages is that the drainage gate and its control device rely on external energy such as electricity in the process of realizing operation, and the cost is relatively high, and the drainage gate and its control device often need to arrange technical personnel for maintenance

In addition, when the water level of the river soars, automatic flooding cannot be realized, and it is still necessary to manually open the gate to release the water
