[0002] In the petrochemical industry, finished or semi-finished oil products need to be stored in storage tanks. During the long-term storage process of the storage tanks, impurities, sand grains, soil, heavy metal salts, and heavy oil components such as paraffin and asphaltene in the oil products will settle naturally due to the specific gravity difference and accumulate at the bottom of the oil tank, forming a black and thick colloidal substance layer, which is the bottom sludge of the oil tank. The bottom sludge at the bottom increases with the increase of the continuous storage time. Over time, the effective volume of the storage tank is reduced, seriously affecting the storage efficiency of the oil tank, and it must be removed regularly.

[0003] At present, the bottom sludge of storage tanks is generally cleaned manually. However, due to the large size of the oil tanks, the labor intensity of the workers is also large; and the interior of the oil tanks is full of flammable crude oil, so the internal environment of the oil tanks is dangerous and prone to fire or even explosion, seriously threatening the lives of the workers.

[0004] Therefore, it is necessary to design a cleaning device for oilfield storage tanks to solve the deficiencies of the prior art. Summary of the Utility Model
