Description

Technical Field

[0001] The present invention relates to the technical field of cleaning platforms, and in particular to a mobile underground well cleaning platform and a cleaning control method. Background Art

[0002] With the vigorous development of my country's aviation industry, the scale of airports has continued to expand, and more and more large airports have laid pipeline networks. As an important part of the aviation fuel supply system, the number of airport apron pipeline valve wells has also increased accordingly.

[0003] According to MH / T6002, "Technical Specifications for the Integrity of Civil Aviation Fuel Equipment," apron pipe network valve wells must be free of water and debris. Seasonal maintenance, inspections, and upkeep are performed every six months. Pipeline network operations require access to valve wells for valve opening and closing. Because valve wells are confined spaces, they must be managed in accordance with special confined space operations.

[0004] Traditional valve well cleaning uses fixed cleaning equipment, which requires laying complex pipelines around the valve well. However, in some busy large airports, there are a large number of valve wells that need to be cleaned every day. Laying pipelines with fixed cleaning equipment takes a lot of time, which reduces the efficiency of valve well cleaning. Summary of the Invention
