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

Embodiment

[0025] Example: Beipanjiang Dongqing Hydropower Station

[0026] (1) Observation background

[0027] Dongqing Hydropower Station is the last cascade of the main stream of the Beipan River, with an installed capacity of 880MW. There are 4 single-unit 220MW hydro-generator sets in total. The normal storage level of the reservoir is 490m, the stagnant water level is 483m, and the limit water level for power generation is 475m. It is a daily regulation reservoir. The elevation of the bottom plate of the tower water inlet is 455m, the elevation of the tower top is 494.5m, the height of the tower is 39.5m, and the front width of the water inlet is 89.2m. The water temperature structure of the reservoir is a transitional type. The floor of the tower water inlet has a height difference of 35m from the normal water storage level. Most of the discharge flow for power generation comes from the water body in the deep-water low-temperature area at an elevation of 455m to 470m in front of t...

Abstract

The invention discloses a floating generating set discharge water temperature observation device and an installation method thereof. The device includes a steel pipe vertically arranged on the inner wall of the tail water platform. The steel pipe is installed on the inner wall of the tail water platform through several brackets. The bottom of the floating ball is connected with a water temperature probe through a connecting chain, a steel cable is installed on the top of the floating ball, and the other end of the steel cable is fixed on the top of the steel pipe. The present invention makes up for the gap in the current systematic observation work of the water temperature change law of the discharge water body of the generator set, improves the technical level and the quality of the results of the observation work of the water temperature change law of the discharged water body of the reservoir in my country, and further improves the mathematical model research on the water temperature change law of rivers in my country, the improvement of the empirical formula and the improvement of the empirical formula. Its computing software development and research work level is of great significance to promote the technological progress of the industry, and its economic, social and environmental benefits are remarkable.

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...
