Gate chamber interior ecological water discharging pipe structure

Abstract

The invention relates to the field of hydraulic engineering and hydroelectric gate chamber equipment, in particular to a gate chamber interior ecological water discharging pipe structure which is simple in arrangement, safe and flexible in usage, small in project amount and capable of saving the investment. An accident gate and a work gate are included. An ecological water discharging pipe is included. The accident gate is arranged in the upstream direction of the work gate. A water inlet of the ecological water discharging pipe is arranged between the accident gate and the work gate. A wateroutlet of the ecological water discharging pipe is formed in the downstream section of the work gate. The gate chamber interior ecological water discharging pipe structure is simple in arrangement, only an extremely short pipeline needs to be arranged, control facility equipment does not need to be independently arranged on the pipeline, accordingly, the project amount is greatly reduced, the costis saved, and the gate chamber interior ecological water discharging pipe structure is particularly suitable for various hydroelectric facilities needing to achieve ecological water discharging.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower sluice chamber equipment, in particular to an ecological discharge pipe structure in the sluice chamber. Background technique [0002] In water conservancy and hydropower projects, in order to meet the ecological water demand downstream of barrage dams, the ecological flow needs to be released downstream during each storage stage of the reservoir. In order to solve the problem of ecological water discharge during the initial water storage of the reservoir and the period when the permanent ecological water discharge channel is unusable, the project generally adopts the method of partially opening the gate of the discharge structure or setting up a temporary water supply tunnel separately. Partially opening the gates of drainage structures to discharge ecological flow often faces the problem of high operating head and small opening, which is likely to cause gate vibration and has a gr...

AI Technical Summary

Problems solved by technology

Partially opening the gates of the discharge structures to discharge ecological flow often faces the problem of high operating water head and small opening, which is likely to cause gate vibration and has a great impact on gate safety

However, the method of setting up temporary water supply tunnels alone has a large amount of work and high investment
