Flywheel energy storage power generation device

The invention relates to the technical field of power generation, and discloses a flywheel energy storage power generation device which comprises a hydraulic station, a hydraulic pipe, a hydraulic cylinder, a flywheel, bearings, a transmission and a generator, the hydraulic station is connected with the hydraulic cylinder through the hydraulic pipe, the bearings are installed on the two sides of the output end of the hydraulic cylinder, and the two bearings are connected with the flywheel and the transmission correspondingly; and the transmission is connected with the generator. According to the flywheel energy storage power generation device, mechanical linear motion is converted into mechanical rotating motion through energy conversion, hydraulic oil is made to do linear reciprocating motion through a hydraulic cylinder by means of a hydraulic station, the flywheel is pushed to do rotating motion, and therefore linear motion is converted into rotating motion, large-torque and low-rotating-speed power output
