System and method considering electric power generation and reduction of water evaporation

Abstract

The present application provides a system and a method considering electric power generation and reduction of water evaporation. The system comprises: a temperature sensor, an illumination intensity sensor, a signal acquisition device, a data transceiving device, a terminal device, a plurality of solar power generation systems, a transformer and a power transmission tower. In this way, the angle between a solar panel and the surface of a reservoir can be automatically adjusted, thereby the projection area of the solar panel on the reservoir surface is changed; the purpose of regulating the water temperature of the reservoir and the illumination intensity is realized; the evaporation of water in the reservoir is effectively suppressed; and a large amount of water resources are saved. Moreover, the present application adjusts the azimuth angle and the elevating angle of the solar panel so that the solar incident light remains perpendicular to the solar panel in time and space dimensions. At the same time, the solar panel always faces the sun in one day so that the thermoelectric efficiency of the solar panel is improved and the electric power generation effect of the solar panel is enhanced; the electric energy generated by the solar panel is transmitted to each electric unit through the transformer and the power transmission tower; and electric power generation is taken into consideration.

Description

technical field [0001] This application relates to the technical field of water conservancy engineering, in particular to a system and method for both power generation and water evaporation reduction. Background technique [0002] Evaporation is one of the leading factors in the natural water cycle process and an important component of the three major elements of water balance. The arid region in Northwest my country is one of the areas with the most severe water shortage in China, with an average annual precipitation of 230 mm and an evaporation capacity of 8 to 10 times that of precipitation. [0003] Taking Xinjiang as an example, the annual average evaporation is 2463.6mm, and the annual average precipitation is only 147mm. At present, 489 reservoirs have been built in Xinjiang, with a total storage capacity of 83.78×10 8 m 3 . Studies have shown that the annual evaporation of plain reservoirs in Xinjiang is 26.1×10 8 m 3 , the lake surface evaporation loss exceeds...

Problems solved by technology

[0011] Although the monomolecular film can inhibit the evaporation of the lake surface of the reservoir is better, but due to the high cost of the monomolecular film, the constraints of factors such as wind force, sand dust, wind and waves in the external environment, its popularization and application is not ideal.
