Abstract

The invention relates to the technical field of power generation equipment, in particular to an energy storage flywheel protection device. The device is used for protecting a flywheel and components of a flywheel under a sudden instability state of the flywheel, so that destructive damage is prevented. The energy storage flywheel protection device comprises a magnetic sucker, a butterfly spring, arotary support, a sensor, a guide column and a pre-tightening nut, wherein the rotary support is internally and fixedly connected with an external bolt, the butterfly spring is added between the magnetic sucker and the rotary support through the guide column, the guide column is in threaded pair connection with the magnetic sucker, the guide column is in sliding pair connection with the rotary support, and pre-tightening is conducted through the pre-tightening nut. The device aims to solve the problem that the impact force of the flywheel cannot be borne by a common bearing.

Description

technical field [0001] The present application relates to the technical field of power generation equipment, in particular to an energy storage flywheel protection device. Background technique [0002] The advantages of flywheel energy storage, such as high power density, long life, stability, environmental protection, and high adaptability to the environment, have gradually been widely used in energy storage, power supply, and energy supplement industries. At present, the impact force of the flywheel falling after instability is borne by ordinary bearings, and because the impact force of the flywheel falling during high-speed rotation is relatively large, ordinary bearings cannot bear it, which will cause serious damage to the internal structure, resulting in Along with economic losses, there are potential safety hazards. Contents of the invention [0003] The present application provides an energy storage flywheel protection device for the above problems. [0004] In o...
