The invention discloses a photovoltaic water pumping energy storage device. The device comprises a photovoltaic power generation device, a water tank, a water pump, a water well, a water turbine, a power generator, a first connecting pipe, a second connecting pipe and a controller, wherein the photovoltaic power generation device and the water tank are adjacently installed on a house roof, and an electromagnetic valve is installed at a water outlet of the water tank; a water inlet of the water pump communicates with the well; a water outlet in the bottom of the water turbine is communicated with the water well; and an input shaft of the generator is in transmission connection with an output shaft of the water turbine. The system is novel in design and simple in structure, overcomes intermittency of a distributed photovoltaic power generation device, avoids the construction of high-investment infrastructures, fully utilizes the height difference between a house and a well and the environmental advantage that the well has sufficient water sources, absorbs light energy through the photovoltaic power generation device, converts the light energy into electric energy, pumps water through a water pump and injects the water into a water tank, and the electric energy is converted into potential energy of water and stored or directly sold to an external state grid.
Description
technical field [0001] The invention relates to the field of renewable energy utilization, in particular to a photovoltaic pumped water energy storage device. Background technique [0002] At present, 75% of China's electricity demand comes from coal. China's rapid economic development and population increase have led to more electricity demand, which in turn intensifies coal consumption. However, coal combustion for power generation will not only release more nitrogen dioxide, oxidation Nitrogen and nitrogen dioxide pollute the air, and also cause a lot of water pollution and noise pollution, so it is becoming more and more important to increase the utilization of renewable energy. Renewable energy is divided into solar energy, wind energy, water energy, biomass energy and tidal energy Compared with other renewable energy sources, solar energy has more mature application technology and lower environmental requirements, which is more conducive to popularization and use.
