A water inlet is provided on the water distribution box. The two sides of the water distribution box are respectively connected to the first self-priming large-flow water pump and the second self-priming large-flow water pump. The first self-priming large-flow water pump and the second self-priming large-flow water pump are respectively connected to the water collecting box through pipes, and the water collecting box is connected to the sprinkler nozzle.
