The present invention discloses a mooring unmanned rotor craft cluster platform system and liquid continuous sprinkling system, and relates to a mooring unmanned rotor craft system and the unmanned aerial vehicle agricultural plant protection technology field. The system comprises a mobile mooring platform, a power supply system, a bollard, a plurality of unmanned rotor crafts, a central control system and the liquid continuous sprinkling system. The power supply system moves along with the mobile mooring platform and provides electric energy to the plurality of unmanned rotor crafts via the bollard, and the bollard is driven to lift off by the plurality of unmanned rotor crafts, so that the bollard can form a spatial three dimensional folded curves in the air to thereby avoid or bypass the obstacles, fit the terrain better and adapt to the terrain change, and the spatial range of the mooring unmanned rotor craft and a task load carried by the mooring unmanned rotor craft in a horizontal direction is increased greatly. The conveying pipelines of the liquid continuous sprinkling system are arranged along the bollard, so that the liquid can be supplied to a nozzle uninterruptedly, and the working efficiency is improved substantially.
