A kind of method, device and equipment for adjusting the benefit of a reservoir in alpine region

Abstract

The invention provides a profiting regulation method, device and equipment for a water reservoir in a high and cold area. The method comprises the following steps: determining change rules of a frozenlayer in the high and cold area; acquiring water volume lost during freezing of water in winter and the water volume increased during ice melting in spring according to the change rules of the frozenlayer in the high and cold area; and by combining the water volume lost during freezing and the water volume increased during ice melting, calculating a profiting scale and maximum water supplying capability of the water reservoir according to a water volume balance principle. According to the method provided by the invention, the problems that an existing water reservoir project is larger in profiting scale and safer and project investment is relatively large are solved, the profiting scale of the water reservoir project is reduced to the utmost extent by calculating the frozen layers, participating in profiting regulation, of the water reservoir in the high and cold area, water supply benefit is increased, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a method and a device for regulating the efficiency of reservoirs in alpine regions. Background technique [0002] Due to the cold and long winter in alpine regions, for example, the winter in Heilongjiang Province lasts from November to April of the next year, which lasts about 6 months, and in March every year, the temperature in mountainous areas is lower than -25°C , the thickness of the frozen layer is more than 1.2m. In addition, the winter precipitation in the alpine region is mainly snowfall, and the generation and confluence are less, resulting in less inflow of the river, or even completely cut off, providing a very limited amount of reservoir inflow. During the design process of the reservoir project, on the basis of meeting the water requirements of the downstream water supply objects, the impact of freezing in winter should be fully considered, ...

AI Technical Summary

Problems solved by technology

During the design process of the reservoir project, on the basis of meeting the water requirements of the downstream water supply objects, the impact of freezing in winter should be fully considered, that is, the scale of the reservoir should be determined on the basis of meeting the engineering tasks, and then the direct impact of the largest frozen layer in winter should be considered. In addition, due to the small amount of storage in cold areas in winter, in order to meet the demand for water supply, it is required that the reservoir project must be large-scale and store as much water as possible during the smooth flow period to meet the needs of the long winter. The downstream water supply demand, the reservoir project determined by this method is relatively large in scale, relatively safe, and the project investment is relatively large
