The invention provides a gravity energy storage system based on a vertical shaft and a roadway. The gravity energy storage system comprises the vertical shaft (1), the roadway (2), an upper rail (3), a lower rail (4), a supporting beam frame (5), a motor generator (6), a winch (7), a lift car (8) and n weight carriers (9). Under the energy storage working condition, one weight carrier (9-n) moves into the lift car (8) from the lower rail (4), the winch (7) is driven by the motor generator (6) to hoist a weight carrier module (9-n) to the top, and then the weight carrier module (9-n) moves to the upper rail (3) from the interior of the lift car (8); and under the energy release working condition, the weight carrier module (9-n) moves into the lift car (8) from the upper rail (3), in the descending process of the weight carrier module (9-n), the winch (7) drives the motor generator (6) to generate electricity, and after the weight carrier module (9-n) falls to the bottom, the weight carrier module (9-n) moves to the lower rail (4) from the interior of the lift car (8) to be parked. The gravity energy storage system can be installed in a mountain or underground, and large-scale energy storage can be achieved.
本发明提出一种基于竖井和巷道的重力储能系统,包括竖井(1)、巷道(2)、上部轨道(3)、下部轨道(4)、支撑梁架(5)、电动发电机(6)、绞盘(7)、轿厢(8)和n个重物载体(9);在储能工况,一个重物载体(9‑n)从下部轨道(4)运动到轿厢(8)内部,通过电动发电机(6)带动绞盘(7)将重物载体模块(9‑n)吊到顶部,然后从轿厢(8)内部运动到上部轨道(3);在释能工况,重物载体模块(9‑n)从上部轨道(3)运动到轿厢(8)内部,重物载体模块(9‑n)降落过程中,通过绞盘(7)带动电动发电机(6)发电,重物载体模块(9‑n)落到底部后,从轿厢(8)内运动到下部轨道(4)停放。重力储能系统可以在山体内部或地下安装,可实现规模化储能。
