TECHNICAL FIELD

[0001] The utility model relates to the field of sanitation vehicles, in particular to a sanitation vehicle box body buffer type flow guide cover. BACKGROUND

[0002] Sanitation vehicles are special vehicles for urban appearance arrangement and cleaning, and they play an important role in urban environmental health management. The water truck is one of the sanitation vehicles. The water truck needs to inject a large amount of water into the vehicle compartment. The impact force of the water column will be applied to the inner wall of the vehicle compartment during water injection. Long-term use will cause damage to the vehicle compartment. Therefore, the impact force of the water column needs to be buffered and guided. However, the common flow guide cover cannot uniformly and effectively distribute the water column. Simply relying on the circular arc plate to guide the water column will still cause the guided water column to impact a certain area. Moreover, at the moment when the water column impacts the flow guide cover, the flow guide cover cannot buffer the impact force. Therefore, the present application provides a sanitation vehicle box body buffer type flow guide cover. SUMMARY
