The working efficiency of river cleaning vessels is far higher than that of traditional manual salvage, with an efficiency improvement of up to dozens of times. Different types of cleaning vessels have different efficiency performances due to differences in functions and specifications, as detailed below:
I. Core Efficiency Advantages: Significant Improvement Compared with Manual Labor
Longer Operation Hours
Manual salvage is limited by weather and physical strength, with daily effective operation hours usually 6-8 hours. In contrast, cleaning vessels (especially solar-powered and unmanned types) can achieve 24/7 uninterrupted operation, requiring only regular docking to clean the garbage storage bin. The daily operation hours are more than three times that of manual labor.
Wider Coverage
Small semi-automatic cleaning vessels: The operation width can reach 3-5 meters, capable of cleaning 10-20 kilometers of river course per day, suitable for narrow inland rivers.
Large mechanical arm cleaning vessels: For example, models equipped with 15-meter dual mechanical arms have an operation width of up to 30 meters, and can clean more than 50,000 square meters of water area per day (equivalent to 7 standard football fields). The daily workload of one vessel is equivalent to that of 50-80 manual workers.
Unmanned cleaning vessels: Through autonomous cruise and path planning, they can cover shoals and bends that are difficult for manual access, achieving dead-corner-free cleaning and avoiding garbage omissions.
Stronger Garbage Disposal Capacity
Cleaning vessels are equipped with special collection bins and automated conveying systems, with a single garbage load capacity of 0.5-5 tons (depending on the model), eliminating the need for frequent round-trip unloading. In contrast, manual salvage mostly uses small tools, with a single load capacity of less than 50 kg, resulting in many round trips and time-consuming labor.
In addition, for stubborn aquatic plants such as waterweeds and water hyacinths, some cleaning vessels have an integrated cutting-crushing-collection function, capable of processing 200-500 square meters of waterweeds per hour, which is 10 times more efficient than manual mowing.
II. Key Factors Affecting Efficiency
Water Environment: In open rivers without complex obstacles, the efficiency of cleaning vessels can be optimized. Narrow rivers with many bends or underwater obstacles will reduce the operation speed.
Garbage Type: Higher efficiency is achieved when cleaning lightweight garbage such as floating plastic bags and leaves. If dominated by large construction waste and heavy waterweeds, the collection bin needs to be cleaned frequently, resulting in a slight decrease in efficiency.
Equipment Configuration: Cleaning vessels equipped with automatic garbage compression functions can reduce unloading times and further improve continuous operation efficiency.
III. Summary
Through the three core advantages of automated operation, wide coverage, and large-capacity storage, river cleaning vessels have achieved a leapfrog improvement in cleaning efficiency, especially suitable for large-scale and regular river cleaning needs. Compared with manual salvage, they not only significantly reduce labor costs and operation risks but also ensure the timeliness and stability of river cleaning, making them the core equipment for modern water environment governance.
