WIPO Patent Application WO/2023/098080
Kind Code:
A1
Abstract:
Disclosed in the present invention is a guide rail mechanism suitable for cleaning a steam generator. The guide rail mechanism comprises a first guide rail and a second guide rail which are in insertion fit with each other, and a line rail arranged on the first guide rail and the second guide rail, wherein a plurality of positioning holes are provided in the line rail, the distance between adjacent positioning holes is the same as that between adjacent heat transfer tubes in the steam generator, and the positioning holes cooperate with a proximity sensor on a cleaning mechanism, so as to achieve stepped positioning of the cleaning mechanism. The guide rail mechanism comprises a first clamping assembly and a second clamping assembly which are arranged on the first guide rail and the second guide rail, and used for clamping a left portion and a right portion, respectively, of a spreader plate in the steam generator. According to the guide rail mechanism suitable for cleaning a steam generator in the present invention, the cleaning mechanism can equidistantly move below the whole-section guide rail mechanism, and the guide rail mechanism is convenient to mount, and is structurally stable after being mounted.
