[0002] Oil field water injection is a measure to inject purified water into the oil layer from the ground in order to maintain the oil layer pressure and improve the oil layer recovery rate. In order to make the oil field continue to have high and stable production and improve the ultimate recovery rate of the oil field, many oil fields at home and abroad adopt the method of injecting water into the oil layer to maintain the formation pressure and improve the oil well recovery rate. Since it is difficult to use pure water for cost considerations, the water body used in water injection needs to be filtered and cleaned before water injection to avoid impurities in the water body during water injection, which may cause blockage of the main water pipe and cause losses. However, the filter modules used in the existing water injection diversion devices are mostly complicated to clean, and the filter modules need to be disassembled for cleaning, which greatly increases the use cost of the water injection diversion device.

[0003] Among them, publication number "CN214035627U" discloses "an oilfield water injection diversion device". This water injection diversion device provides an idea of ​​setting components such as cross bars, rotating shafts, annular scrapers, straws, and nozzles from the aspect of facilitating the cleaning of the filter module, and has high practicality. However, this water injection diversion device still has certain shortcomings in actual use. Although this water injection diversion device allows the filter module to be cleaned without being disassembled through many components, it not only needs to spray water inward to flush the barrel, but also needs to shake the handle to operate, which requires manual intervention. For this reason, the utility model provides an oilfield water injection diversion device. Utility Model Content
