Floating generating set discharged flow water temperature observation apparatus and installation method thereof

Abstract

The invention discloses a floating generating set discharged flow water temperature observation apparatus and an installation method thereof. The observation apparatus comprises a steel pipe vertically arranged on the inner wall of a tailrace platform. The steel pipe is installed on the inner wall of the tailrace platform through a plurality of supports. A floating ball is disposed in the steel pipe. The bottom of the floating ball is connected with a water temperature probe through a connection chain. A steel cable is installed on the top of the floating ball. The other end of the steel cable is fixed to the top of the steel pipe. The floating generating set discharged flow water temperature observation apparatus fills a blank of the observation of a conventional generating set discharged water temperature change rule system, has important significance to improvement in the technical level and accomplishment quality of China reservoir discharged water temperature change rule observation, further promotion of China river water temperature change rule mathematic model research, improvement in empirical formulas and calculating software development research level, and promotion of industrial technical progress, and has obvious economic social, and environmental benefit.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering monitoring, in particular to a discharge water temperature observation device of a floating generator set and an installation method thereof. Background technique [0002] At present, there are few systematic observations of water temperature changes in the discharge water body of hydropower project generating units in my country, especially for the impact of low-temperature water discharge from high-dam and large reservoirs in hydropower projects. Between the vertical water body and the observation work of the water temperature change law of the discharge of the generating set, there are generally problems of uncoordinated work requirements and mismatching results. The change law of discharge water temperature is not pertinent, resulting in systematic, representative, and unreliable problems in the quality of the observation results of the overall water temperat...

Problems solved by technology

[0002] At present, there are few systematic observations of water temperature changes in the discharge water body of hydropower project generating units in my country, especially for the impact of low-temperature water discharge from high-dam and large reservoirs in hydropower projects. Between the vertical water body and the observation work of the water temperature change law of the discharge of the generating set, there are generally problems of uncoordinated work requirements and mismatching results. The change law of discharge water temperature is not pertinent, resulting in systematic, representative, and unreliable problems in the quality of the observation results of the overall water temperature change law in the reservoir area and downstream of the hydropower project. , improvement of empirical formulas and development of calculation software are of little reference value
