A water temperature comparison observation system on both sides of the front retaining wall of the reservoir

Abstract

The invention discloses a water temperature comparison observation system on both sides of a front retaining wall of a reservoir, which comprises a retaining wall located upstream of the water inlet of the reservoir, the retaining wall is vertically arranged on the foundation of the retaining wall, and Vertical perforated steel pipes are respectively arranged on both sides of the body, and a number of water temperature online observation probes are arranged in the vertical perforated steel pipes. face. The system of the present invention effectively covers the observation of the warming effect of the front retaining wall of the reservoir, ensuring the systemicity, representativeness and reliability of the overall observation and research results of the reservoir and downstream water temperature change laws; It is of great significance to improve and optimize the design, construction and operation scheduling of water intake measures for the front retaining wall of subsequent water conservancy and hydropower projects.

Description

technical field [0001] The invention belongs to the technical field of hydrological observation of water conservancy and hydropower projects, and in particular relates to a water temperature comparison observation system on both sides of a retaining wall in front of a reservoir. Background technique [0002] The hydrological situation and water body environment of the reservoir area have been changed after the water conservancy and hydropower projects and other hydraulic constructions have been built into the reservoir. Considering the stratified water intake measures to take the water body in the high temperature area of ​​the surface layer of the reservoir, most of the discharge flow of the reservoir comes from the water body in the deep water low temperature area of ​​the reservoir area, and the low temperature water discharge of the reservoir will have a long-term and far-reaching impact on the downstream river water ecosystem. [0003] At present, my country's water con...

AI Technical Summary

Problems solved by technology

[0003] At present, my country's water conservancy and hydropower projects usually adopt the method of setting a front retaining wall in front of the water inlet to use the surface water of the reservoir to generate electricity or divert water, so as to slow down the impact of the low-temperature water discharged from the original reservoir inlet on the downstream river water ecosystem, which has been gradually popularized. However, the observation work of the warming effect system of the front retaining wall in water conservancy and hydropower projects is still in a blank stage, and the technical methods and requirements for the observation work of the warming effect system of the front retaining wall lack the effective unity of relevant guidelines or specifications, resulting in the reservoir and the downstream as a whole The observation of water temperature change law and the quality of research results generally have problems such as systematicness, representativeness, and low reliability. It is a reference for improving and optimizing the design, construction, and operation scheduling of water intake measures for the front retaining wall in subsequent water conservancy and hydropower projects. It is of little significance, and it is of little significance to improve the research on the mathematical model of the change law of river water temperature in our country, the improvement of empirical formulas and the development of calculation software, and to promote the scientific and technological progress of the industry.
