The core working principle of a river cleaning vessel is to achieve integrated operation of “collection-transportation-storage-unloading” of floating debris such as garbage and aquatic plants through the linkage of mechanical structures. The workflow varies slightly among different types of vessels (e.g., salvage ships, weed-cutting ships, unmanned intelligent ships), with the following core steps:
1.Front-end Collection Stage
For floating garbage (plastic bottles, foam, branches, etc.): The bow is equipped with salvage arms, nets or conveyor grilles. As the vessel moves forward, the thrust drives garbage into the collection area. Some large-sized vessels allow adjustable salvage arm width to expand the operation range.
For aquatic plants (waterweeds, water hyacinths, etc.): Weed-cutting vessels are fitted with rotary cutting blades that first chop plants into small segments, then gather them to the collection port via a convergence device.
2.Mid-stage Conveying and Filtration Stage
Garbage/aquatic plants from the collection port are transported to the onboard storage cabin via a roller conveyor belt. The belt surface is designed with drainage holes to quickly drain water, reducing the vessel’s load and improving operational efficiency. High-end models are equipped with additional filters to capture microplastics larger than 0.5 millimeters.
3.Storage Stage
Dehydrated waste is transferred to the ship’s closed garbage bin, which is fitted with anti-spill baffles to prevent waste from falling back into the water during transportation. Small-sized cleaning vessels use detachable bins, while large-sized ones are equipped with hydraulically liftable storage silos.
4.End-stage Unloading Stage
When the bin is full, the hydraulic system tilts and lifts the storage silo, or reverses the conveyor belt to rapidly unload waste into shore-based garbage trucks, completing one operation cycle.
5.Intelligent Control Stage (Exclusive to Unmanned Cleaning Vessels)
Relying on millimeter-wave radar + visual recognition + GPS positioning technology, the vessel achieves autonomous route planning and precise obstacle avoidance (e.g., bridge piers, ships, shoals). Sensors monitor the bin’s full status and the vessel’s battery life in real time, supporting remote one-click start/stop and route adjustment. Some models can simultaneously collect water quality data.
