[0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons. It is a viscous, dark brown liquid with a natural appearance. It is called the "blood of industry". Petroleum is mainly used as fuel and gasoline. It is also the raw material for many chemical industrial products, such as solutions, fertilizers, pesticides and plastics. Petroleum needs to be stored in storage tanks. At present, before the use of petroleum storage tanks, the welds, wall thickness, etc. of the storage tanks need to be inspected by non-destructive testing instruments. Due to the large size of the storage tanks, it is very difficult to perform tumbling inspections, and the inspection is relatively inconvenient. In addition, the outer surface of the tank is often stained with a large amount of dust, soil and rust due to various external factors, which affects the accuracy of the inspection of the petroleum storage tanks. Therefore, we proposed a non-destructive inspection rotary device for petroleum storage tanks to solve the above problems. Utility Model Content
