The system works in the same way as boats, even with modestly sized debris, they move when they arrive, allowing the debris to pass through, and then back into position. The anchorage of the floating devices is designed so that it detaches in the event of a very strong impact.
The floating device is equipped with GPS inside the floating buoy, in case of impact they are then recovered. The system is designed to require the least possible maintenance, in case of failures or blocks these will probably be limited to the single rotating units. The river cleaning system is anchored to the bottom in the frontal position, so the current keeps them parallel to the watercourse and in the correct position. Depending on the initial installation, they are arranged and calibrated so as to reposition themselves on the axis even if subject to shocks or variations in the intensity of the current.
The ropes to which they are anchored, have sufficient length to allow the devices to remain functioning in a wide range of river level variation. When the water level changes, the angle with which the ropes connect to the units will also vary. The river cleaning system provides different types of anchoring according to the needs of the river.
We cannot indicate the type of anchorage unless we first know the specific characteristics of the river. In the case of large water courses, or with particular characteristics, the modular system allows more consecutive lines to be arranged, the devices can also have very different dimensions, in order to adapt to the best environment and plant requirements.

If you are an operator who can facilitate efforts to clean local waterways, a local government that is actively ready in its territory to solve the pollution problem or you are a company that would like to finance this revolutionary technology, all you have to do is wtrite us an email. You can arrange a standard collection point that contains the waste and can then be picked up and replaced comfortably.
Alternatively, a separator system can be installed which divides the waste at the moment. River Cleaning System. Why revolutionize everything? But unless the flow of garbage is stanched at the source, cleanup can only ever be a rearguard solution. The catamarans 24 metres long and 8.
The screens, located near midships, are designed to pick up small debris which is then deposited into storage containers located on deck. Larger debris is captured at the bow in coarse mesh buckets, which also allows the smaller items to pass through and move towards the finer debris screens that are found midships. In the US, skimmer boats have been in use since the early s. United Marine International manufactures the TrashCat, which comes in 3 sizes pictures below.
They are capable of collecting up to cubic feet 34 cubic meters of floating debris per load. US company Alpha Boats sells similar machines.
The invention is more specifically directed to highly maneuverable vessels equipped with means for picking up floating debris, means for storing the debris on the vessel, and means for discharging the debris from the vessel to a storage area, which may be ashore or which may be another vessel such as a barge. Many work boats and vessels have been proposed for collection of floating solid waste and other debris.
These may typically be formed as a catamaran-type hull, i. In one typical trash skimmer design, one or more hydraulically powered open mesh conveyors are positioned between the pontoons of a catamaran-type twin-hull vessel.
Twin over-the-rear propellers are used to propel and maneuver the vessel, and these can be tipped up for cleaning weeds and debris from the propeller blades. A main pickup conveyor extends off the front end, and extends into the water to catch the floatables, which it picks up and carries back to a main storage conveyor. When the storage conveyor is completely loaded, the boat is taken to a discharge position where the debris can be transferred to a truck or barge or other facility.
A rear conveyor at the stern of the craft carries the debris from the storage conveyor up and back to drop it into the barge or on-shore storage facility.
In some cases, a separate, on-shore conveyor can be used to pick up the trash discharged from the vessel. In the vessels of this type, the debris or trash is picked up and loaded from the front, and is discharged from the rear or stern of the vessel.
This means that there have to be three conveyor system, i. Second, because the region of the vessel on the centerline and sternward of the storage conveyor is occupied by the discharge conveyor, the motor, the cockpit or operator control position, and any other necessary equipment have to located to one side or the other, usually atop one of the pontoons.
The control position may be located on a bridge standing over the storage area. A number of skimmer boats of various designs for collection of floating solid debris have been proposed, for example, in U.
At present, there are no skimmer boats designed for loading and discharge from the same end using the same conveyor. Also, there are no work boats in which an auxiliary portion of the hull can be added for extra flotation for the forward conveyor, and can be removed to keep the vessel narrow enough to be trucked or trailered on a roadway.
It is another object to provide a trash skimmer of improved design to facilitate loading of trash onto the vessel and discharge of trash from the vessel. It is a further object to provide a trash skimmer vessel that is stable and easily maneuverable in the water, simple to operate for collection and discharge operations, and is easily trailerable for transportation by roadway between work sites.
According to one aspect of this invention, a trash collection skimmer boat is designed for collecting trash in a harbor, canal, lakeshore, or other body of water and later discharging the collected trash to a discharge station, i. The skimmer's flotation hull can favorably be of an open design, in which there are left and right i. A storage conveyor positioned on the boat hull, favorably approximately amidships and along the center line.
In a favorable embodiment, the storage conveyor has an open mesh web that travels over forward and aft rollers that define forward and aft ends of the storage conveyor. The storage conveyor is mounted to the hull on a slide or track arrangement that permits motion fore and aft for a limited distance relative to the hull. An actuator, i. A forward conveyor is mounted at the bow portion of the hull and is used for picking up trash or debris from the body of water and transferring the same to the storage conveyor.
The forward conveyor is also used discharging the trash or material stored on the skimmer boat to a discharge station. A frame of the forward conveyor extends past the bow of the trash skimmer. The frame is mounted to the hull so that it can be tilted at a range of angles, up and down, and so that the proximal end of the forward conveyor can be positioned above or below the distal or forward end of the storage conveyor. The forward conveyor favorably has an open mesh web, and fore and aft rollers over which the web travels and defining distal and proximal ends of the forward conveyor.
The forward conveyor can be oriented by the operator, such that in a trash collection position the proximal end of the forward conveyor is positioned above the forward end of the storage conveyor, and in a trash discharge position the proximal end of the forward conveyor is positioned below the forward end of the storage conveyor. The storage conveyor is brought sternward so that there is clearance for the proximal end of the forward conveyor to be raised or lowered, and then is brought back forward so that the storage conveyor is in position to receive the trash and debris from the forward conveyor or to discharge the trash and debris onto it.
At the front or distal end of the forward conveyor there are preferably also a pair of supplemental conveyors. These are respectively carried on left and right jaw members or wings. These jaw members are articulated so that they can open and close laterally. This enables the front conveyor to pick up debris from a wide area at the front of the vessel.
The jaws can be narrowed when loading from a narrow area, i. The engine for the vessel, which also powers the conveyors and the actuator, is mounted on the hull, favorably sternward of said storage conveyor and on the centerline.
In one favorable embodiment, a stern hull portion is situated beneath the engine, such that the port and starboard pontoon members extend forward from the sides of the stern hull portion. This hull portion at the stern end provides plenty of buoyancy at the position of the engine. Favorably, the hydraulic pump and associated equipment are located adjacent the engine, and the hydraulic reservoir and valving are preferably located between the engine and a stern wall of the storage conveyor.
A pair of demountable auxiliary floats or sponsons are mounted outward of main hull on the port and starboard sides to provide additional floatation for the front conveyor when the boat is in the water. These auxiliary floats are removed from the hull when the boat is out of the water and needs to be transported by truck or trailer.
