Description

Technical Field

[0001] The present invention relates to the technical field of dust-proof sheds, and in particular to an intelligent automated multi-station unit maintenance smoke and dust purification dust-proof shed and its usage method. Background Art

[0002] The A / B-level maintenance work of the basin power station unit is an important link to ensure the normal operation of the power station. During this period, it is essential to carry out maintenance operations such as rust removal, grinding, and welding on key components such as the top cover, movable guide vanes, guide vane sleeves, and water seals. However, a large amount of dust and smoke are generated during these operations, posing a potential threat to the health of the operators.

[0003] Currently, temporary covers are usually used to isolate the operation area to reduce the diffusion of dust and smoke. However, the existing temporary covers have a simple structure. Although they play a role in reducing the diffusion of smoke and dust, they cannot effectively purify the smoke and dust. Especially when multiple workstations are grinding simultaneously, a large amount of smoke and dust is generated. There is also a method of using a dust collector with a suction pipe to absorb smoke and dust. However, usually, manual adjustment of the suction component to a specified position is required to achieve smoke and dust absorption. It is impossible to detect the smoke and dust at the workstations and impossible to achieve automated mobile dust suction, which is inconvenient to use. Therefore, an intelligent automated multi-station unit maintenance smoke and dust purification dust-proof shed is needed to improve the above problems. Summary of the Invention
