Abstract: A fast blind plate switching device is provided, including a sealing structure, a clamping structure, a support structure and an execution mechanism. The blind plate has an open-state and a blind-state. The support structure is used for connecting pipelines at two sides and providing support for the whole device. The clamping structure and the sealing structure are located inside the support structure. The clamping structure is driven by the execution mechanism, and under the drive of the execution mechanism, the clamping structure presses on the blind plate to eliminate a gap between two sides of the blind plate, so that sealing is formed by means of the sealing structure. When a gap is formed away from the blind plate, the open/state and the blind state of the blind plate is switched.
