Flywheel energy storage device capable of automatically balancing in vacuum environment

Abstract

The invention discloses a flywheel energy storage device capable of automatically balancing in a vacuum environment, and the flywheel energy storage device capable of automatically balancing in the vacuum environment comprises a housing, a motor, a flywheel rotor, a plurality of counterweight parts, a signal collection assembly and a control assembly, the plurality of counterweight parts are arranged on the flywheel rotor and can be locked and released with the flywheel rotor, the signal acquisition assembly is in communication connection with the control assembly, the signal acquisition assembly can calculate the unbalanced mass of the flywheel rotor, and the control assembly can control any one of the plurality of counterweight parts to be locked and released with the flywheel rotor according to the unbalanced mass of the flywheel device. According to the flywheel energy storage device capable of balancing automatically in the vacuum environment, on the premise that the flywheel energy storage device is not disassembled and an operation window is not reserved, online dynamic balance of the flywheel rotor can be achieved, and efficient operation and sealing performance of the flywheel energy storage device are guaranteed.

Description

technical field [0001] The invention relates to the technical field of flywheel energy storage, in particular to a flywheel energy storage device that automatically balances in a vacuum environment. Background technique [0002] The balancing process of the flywheel rotor in the relevant technology includes offline dynamic balancing and online dynamic balancing. Offline dynamic balancing needs to be carried out on a balancing machine, which is costly and difficult to guarantee the balance accuracy due to the inconsistency between the rotating speed and the working speed during balancing. [0003] However, when the online dynamic balance in the related art increases or reduces the weight of the flywheel, it is necessary to reserve an operation window or disassemble the open flywheel. There are various problems in both methods. For example, the reserved operation window will affect the airtightness of the flywheel energy storage device. , and repeated disassembly of the flywhe...

[0002] The balancing process of the flywheel rotor in the relevant technology includes offline dynamic balancing and online dynamic balancing. Offline dynamic balancing needs to be carried out on a balancing machine, which is costly and difficult to guarantee the balance accuracy due to the inconsistency between the rotating speed and the working speed during balancing.

[0003] However, when the online dynamic balance in the related art increases or reduces the weight of the flywheel, it is necessary to reserve an operation window or disassemble the open flywheel. There are various problems in both methods. For example, the reserved operation window will affect the airtightness of the flywheel energy storage device. , and repeated disassembly of the flywheel will reduce the operating efficiency of the flywheel, and there will be assembly accuracy problems
