Embodiments of the present disclosure relate to a water body pollution intelligent investigation method and device based on unmanned ships. The method includes: determining a first pollutant concentration value of a monitored water area according to water quality data of the monitored water area; controlling an unmanned ship to cruise in the monitored water area according to a preset cruise trajectory and perform water quality collection to obtain a second pollutant concentration value of the monitored water area; determining, when there is an abnormal cruise coordinate point, a target cruise trajectory according to the second pollutant concentration value of the abnormal cruise coordinate point; and controlling the unmanned ship to cruise according to the target cruise trajectory to determine a pollution source of the monitored water area.

Systems and methods can support an autonomous pool skimming system. The pool skimming system may have a body with two or more hulls. Two or more paddlewheels may be coupled to the body. An independent motor may drive each paddlewheel. The motors may be independently controllable to support steering. The pool skimming system may have one or more processing units, two or more distance sensors, one or more solar cells, and a power supply operable to power the processing units and the motors from energy supplied by the solar cells. One or more processing modules may configure the processing units to plan and execute a traversal path across the surface of a body of water, such as a swimming pool, to collect debris into a removable basket. A portion of the traversal path may be established according to signals from distance sensors.

A waste management system for plastic or other material floating on the surface and in the subsurface of a body of water. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is frozen to a temperature at or below minus fifty degrees Fahrenheit, using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon may be recycled or used as fuel by the ship. Water may be used by the ship or returned to the ocean.

Systems, apparatus and methods useful for collecting debris from a body of water on a vessel having at least one cargo compartment and at least a first pump fluidly coupled to at least one cargo compartment and configured to concurrently draw water and debris from the body of water into, and remove water from, the cargo compartment(s) include at least a second pump, distinct from the first pump and configured to remove debris from at least one cargo compartment.

A towing apparatus has a spine with multiple generally parallel spine members extending in a longitudinal direction and having a length of at least 100 m, and with a leading end and a trailing end. A series of blades are mounted to the spine by couplers which allow the blade to rotate about an axis substantially transverse to the longitudinal direction, each blade having a first surface facing generally in the trailing end direction and a second surface facing generally in the leading end direction. Restraints prevent rotation of each blade by more than a pre-set amount towards the leading end, so that impingement of a wave on the first surface applies a force to the apparatus in the leading end direction. A pair of the towing apparatus' may be arranged to connect to a floating collector with a beach shape to collect floating debris on the sea surface, ridges helping to retain the debris on the slope until it is washed up into a channel.

A multifunctional ship for the collection and recycling of ocean debris and the system thereof may include a hull; a detection device provided on the hull to detect ocean debris floating on the sea or deposited on the seabed; a collection device installed on the hull to collect the ocean debris detected by the detection device; a sorting device installed on the hull to sort the ocean debris collected by the collection device; a compressing device installed on the hull to compress the sorted ocean debris to compress and remove moisture and reduce the volume; a waste plastic recycling device installed on the hull to produce recycled oil by thermally decomposing the waste plastic compressed in the compressing device; a storage tank installed at the bottom of the hull to store the recycled oil produced; and a purifier for purifying wastewater generated in the process of producing recycled oil.

A floating oceanic debris collection device may include a circular base, a debris collection unit, and a debris storage unit. The debris collection unit may include a blade erected on an upper surface of the base and an arm extending in an outward direction to a rotation direction side. The debris storage unit may include an annular inner peripheral float installed on a lower surface of the base, an inlet penetrating a peripheral surface of the inner peripheral float, and an outlet penetrating the upper surface of the base. An entirety of the base may be configured to rotate via receiving wind on the sea with the blade. The arm may be configured to scrap debris floating on a sea surface inward. The inlet may be configured to introduce the debris to an inside. The outlet may be configured to facilitate removal of the debris from the debris storage unit.
