Energy-storage power-generation reservoir

Abstract

The invention discloses a novel energy-storage power-generation reservoir, comprising an underground reservoir, a heat exchange system and an expanding work-applying power generation device. The novel energy-storage power-generation reservoir can store ice in winter and store hot water in summer. The expanding work-applying power generation device generates power by the using temperature difference of winter and summer air and the hot water or the ice of the underground reservoir; and the underground reservoir is built under the ground and is obtained in manners that grooves, valleys and the like with proper water conditions, weather conditions and geological conditions are subjected to construction technology and impermeable heat-proof treatment, and a high-quality cultivated land is manufactured by covering soil on the top. The energy-storage power-generation reservoir not only can store and supply water but also can fully utilize heat energy in summer and cold amount in winter in the natural environment, can generate power, does not occupy land resource and can build the cultivated land.

Description

technical field [0001] The invention relates to a reservoir, in particular to an energy storage and generating type reservoir. Background technique [0002] At present, the known reservoirs are all open-air, occupy land resources, store water in wet seasons, and supply water in dry seasons. They only play a simple role in water storage, and cannot utilize heat energy in summer and cold energy in winter. Contents of the invention [0003] In order to overcome the fact that the existing reservoirs are all open-air, occupying land resources, storing water in the wet season and supplying water in the dry season, which only play a simple role in storing water and cannot utilize the heat energy in summer and the cooling capacity in winter, the present invention provides a An energy-storage and power-generating reservoir includes an underground reservoir, a heat exchange system, and an expansion power generation device. The energy-storage power generation type reservoir achieves...
