▎ 摘　　要

NOVELTY - The system (100) has a vessel (106) which is placed in the water body. The conveyor belt is configured with a net operatively coupled to the vessel. The conveyor belt with the net is adapted to collect rubbish from the water body such that the collected rubbish comprising wet rubbish and dry rubbish. The two containers comprise the first container and the second container. The first container and the second container adapted to store the separated dry rubbish and the wet rubbish respectively. A rubbish compressing unit (114) is operatively coupled to the rubbish separating unit (110) and to the rubbish storing unit (112), and configured to compress the separated dry rubbish to increase space for storage in the first container. A water filtering unit (116) is operatively coupled to the rubbish storing unit, the water filtering unit configured to extract water from the separated wet rubbish and purify the extracted water by removing solid wastes and impurities from the extracted water. USE - System for cleaning water body such as oceans, seas, river, ponds and swimming pools. ADVANTAGE - The system performs the efficient cleaning of water bodies by removing industrial rubbish and other chemical pollutants from the water bodies in real-time. The system is provided for cleaning or purifying a water body by collecting and removing rubbish present in/on the water body. The system is provided for cleaning or purifying a water body by collecting and removing rubbish present in/on the water body automatically. The simple and cost effective system is provided for cleaning or purifying a water body by collecting and removing rubbish present in/on the water body. The precise and time efficient system is provided for cleaning or filtering a water body by collecting and removing pollutants such as rubbish, plastic etc. present in/on the water body. The system is provided for cleaning or filtering a water body completely by collecting and removing rubbish present in/on the water body and without using any chemical based water filters. The system is provided for cleaning or filtering a water body completely by collecting and removing rubbish present in/on the water body in real-time and with reduced labor. DETAILED DESCRIPTION - The rubbish separating unit is operatively coupled to the vessel and to the conveyor belt. The rubbish separating unit comprising the sieve adapted to separate the dry rubbish and the wet rubbish from the collected rubbish. A rubbish storing unit is operatively coupled to the rubbish separating unit. The rubbish storing unit comprises two containers. The water filtering unit comprises filter. The filter is a graphene coated polyurethane (PU) foam based filter configured with bamboo fibers. The filter is adapted to purify the extracted water by removing solid wastes and impurities from the extracted water. The graphene coated PU foam based filter is adapted to implement graphene sand to purify the extracted water. The vessel is a robotic vessel. The vessel is selected from any of a boat, ship, ferry, yacht and watercraft. The water filtering unit comprises the filter. The filter is a graphene coated PU foam based filter configured with bamboo fibers. The filter is adapted to purify the extracted water by removing solid wastes and impurities from the extracted water. An INDEPENDENT CLAIM is included for a method for cleaning a water body, involves collecting rubbish from the water body by using at least one conveyer belt configured with the net operatively coupled to a vessel placed in the water, such that the collected rubbish comprising wet rubbish and dry rubbish. The dry rubbish and the wet rubbish are separated from the collected rubbish, by using the sieve of a rubbish separating unit. The separated dry rubbish and the wet rubbish are respectively stored, by using the first container and the second container of a rubbish storing unit. The separated dry rubbish is compressed, by using a rubbish compressing unit, to increase space for storage in the first container. The water from the separated wet rubbish is extracted, by using a water filtering unit. The extracted water by removing solid wastes and impurities from the extracted water is purified, by using the water filtering unit.
