Description

Technical Field

[0001] The present invention relates to the technical field of runner maintenance, and in particular to an airbag-based runner maintenance operation platform system. Background Art

[0002] As a key component for energy conversion, the runner of a hydro-generator set will have problems such as wear and fatigue cracks during long-term power generation in a hydropower station. Therefore, the runner needs to be regularly maintained.

[0003] Currently, the maintenance of the runner of a hydro-generator set is operated through an airbag maintenance platform. The current airbag-based operation platform has the following disadvantages: insufficient load-bearing capacity compared to scaffolding; poor mobility and inability to cover the entire runner maintenance; and no solution to the safety protection problems during the construction of the maintenance platform and the use of the operation platform. Therefore, it is necessary to design an airbag-based runner maintenance platform system with strong load-bearing capacity, convenient movement, and high safety factor. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the specification of this application, to avoid obscuring the purpose of this part, the abstract, and the title. However, such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the problems of the existing maintenance platform with insufficient load-bearing capacity, inconvenient movement, and low safety factor, the present invention is proposed.
