Self-balancing flywheel energy storage device in vacuum environment

Abstract

The invention discloses a self-balancing flywheel energy storage device in a vacuum environment. The self-balancing flywheel energy storage device in a vacuum environment comprises a casing, a motor, a flywheel rotor, a plurality of counterweights, a signal acquisition component and a control component , the motor and the flywheel rotor are both arranged in the housing, a plurality of counterweights are arranged on the flywheel rotor and can be locked and released with the flywheel rotor, the signal acquisition component and the control component are connected in communication, and the signal acquisition component can calculate the flywheel rotor For the balance mass, the control assembly can control any one of the plurality of counterweights to lock and release with the flywheel rotor according to the unbalanced mass of the flywheel device. The self-balancing flywheel energy storage device in the vacuum environment of the present invention can realize the online dynamic balance of the flywheel rotor without disassembling the flywheel energy storage device and the reserved operation window, and ensure the efficient operation and sealing of the flywheel energy storage device. .

Description

technical field [0001] The invention relates to the technical field of flywheel energy storage, in particular to a flywheel energy storage device that is automatically balanced in a vacuum environment. Background technique [0002] The balancing process of the flywheel rotor in the related technology includes off-line dynamic balancing and on-line dynamic balancing. Off-line dynamic balancing needs to be carried out on a balancing machine, which is costly and difficult to ensure the balancing accuracy due to the inconsistency between the rotational speed during balancing and the working rotational speed. [0003] In the related art, when the online dynamic balancing increases or decreases the weight of the flywheel, it is necessary to reserve an operating window or remove the open flywheel. Both methods have various problems. For example, the reserved operating window will affect the airtightness of the flywheel energy storage device. , and the repeated disassembly of the fl...

Problems solved by technology

[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
