Gravity energy storage device

Abstract

The invention relates to a gravity energy storage device. The gravity energy storage device comprises a control module, a hanging basket, an elevated side beam, fixed pulleys, movable pulleys, a guidewheel, a winch, a cable, a transmission and an electric generator, wherein the hanging basket is a gravity carrier, the fixed pulleys are connected to the elevated side beam, the movable pulleys areconnected to the hanging basket, one end of the cable is connected to the elevated side beam and is connected to the winch through the guide wheel after pass around all the movable pulleys and the fixed pulleys; the control module controls the energy inputting, storing and outputting of the gravity energy storage device the winch is provided with a brake, the winch is connected with the electric generator through a transmission, the control module controls the electric generator to rotate, the winch is driven to roll up the cable to increase the energy input of the hanging basket, and the control module controls the electric generator to stop rotating to store energy; and the hanging basket descends, and the cable pulls the winch to drive the electric generator to generate electricity forpower output. According to the device, the energy can be stored and utilized, the structure is simple, the manufacturing cost is low, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to a gravity energy storage device. Background technique [0002] The development and utilization of renewable energy will usher in a period of great development in the near future. In renewable energy, solar and wind power generation is unstable, so many energy storage technologies are needed to adjust peaks and fill valleys. At present, pumped energy storage is the most used, but pumped energy storage depends on natural conditions, so the quantity is limited, and it is far from enough to rely on pumped energy storage to adjust peaks and fill valleys. However, large wind farms and large solar power plants often require larger energy storage equipment, and the cost of using batteries for energy storage is too high, and the batteries will decay and age after 2 to 3 years of use, and the power storage will decline.
