[0026] DETAILED DESCRIPTION OF THE INVENTION

[0027] In this detailed description the subject matter of the invention are described with examples only for a better understanding of the subject in a non-limiting sense.

[0028] Fig. 1 shows a representative isometric view of the surface cleaning system (10) of the invention. Said surface cleaning system (10) is configured to collect waste on the sea surface. To achieve this, the surface cleaning system (10) is connected to a main body (20) with at least one collecting port (21 ) opening into a chamber where the waste is collected. Said main body (20) may be a body floating in water, a body of a watercraft, or any other body close to the seashore or similarly, sea surface. The figures show said surface cleaning system (10) of the invention as it is integrated into a main body (20) which may move in water and has its own motor. In this embodiment, the main body

[0029] (20) is an autonomous marine vessel which may be controlled remotely.

[0030] The surface cleaning system (10) includes at least one movable arm (30). Said movable arm (30) serves to direct the waste from the sea surface to the collecting port

[0031] (21 ). Therefore, the movable arm (30) surrounds the waste on the sea surface and pulls it towards the collecting chamber. The movable arm (30) contains a guide end (32) with at least one guiding mechanism (321 ) to provide this motion. The guide end (32) is the end of the movable arm (30) away from the main body (20). Fig. 2 shows a representative zoomed-in isometric view of the guiding mechanism (321 ). Said guiding mechanism (321 ) enables the movable arm (30) to be activated on the sea surface with at least one drive element (322) located therein, so that the movable arm (30) may surround the wastes on the sea surface. The drive element (322) may be a propeller in a possible embodiment. The surface cleaning system (10) preferably includes two movable arms (30). In this way, a larger area on the sea surface may be reached.

[0032] The movable arm (30) contains at least one flexible body (31). Said flexible body (31 ) allows the movable arm (30) to move freely and surround the wastes due to the elastic structure thereof. In a preferred embodiment, the flexible body (31 ) is a hose. However, the flexible body (31) may be any flexible material (a net, etc.) which may move the wastes when it is moved by contacting the wastes. The drive element (322) is connected to the guide end (32) of the flexible body (31) away from the main body (20) to allow the movable arm (30) to be easily moved to the desired area.

[0033] The movable arm (30) contains at least one hook (323). Said hook (323) allows the movable arms (30) to be interlocked with each other after surrounding the waste. The hook (323) is positioned at the guide end (32) of the movable arm (30). The hook (323) is connected to at least one locking motor (324), which activates the hook (323) to be coupled with the opposite movable arm (30) and allows the hook (323) to be opened and closed.

[0034] The movable arm (30) is connected to at least one float (325). Said float (325) allows the movable arm (30) to float on the surface of the sea. The float (325) is also connected to the guide end (32) of the movable arm (30), ensuring the entire flexible body (31 ) to remain in line with the sea surface.

[0035] The surface cleaning system (10) includes at least one pulley (35). Fig. 3 shows a representative zoomed-in isometric view of the pulley (35) portion. The flexible body (31 ) of the movable arm (30) may be rolled up by being wrapped on said pulley (35) and may be unwrapped to reach the sea surface. The pulley (35) is connected to at least one rotation motor (351 ). The rotation motor (351 ) serves to rotate the pulley (35) around itself. Accordingly, when the pulley (35) rotates in one direction, the movable arm (30) unwraps and extends on the sea surface, and when it rotates in the other direction, the movable arm (30) is wrapped around the pulley (35) and rolled up. There is at least one shaft (36) between the pulley (35) and the rotation motor (351), which transmits the motion in the rotation motor (351 ) to the pulley (35).

[0036] In the surface cleaning system (10), the movable arms (30) are controlled by means of the cables (33). The cables (33) extend together with the movable arm (30) and provide energy for the drive element (322) which activates the movable arm (30). The wired (33) control of the surface cleaning system (10) eliminates the need for additional batteries for the movable arms (30) and prevents power cuts.

[0037] In the preferred embodiment, the flexible body (31 ) is a hose, and the cables (33) pass through the hose. There is at least one anti-entanglement bearing (34) to prevent the cables (33) from becoming entangled during the rotation of the pulley (35). The antientanglement bearing (34) includes at least one movable bearing (342) and at least one fixed bearing (341 ). The movable bearing (342) is fixed on the shaft (36) and makes a rotational motion with the shaft (36). The fixed bearing (341) is positioned around the movable bearing (342). The movable bearing (342) and the fixed bearing (341 ) are connected in such a way that there is a freedom of rotation therebetween relative to each other around the extension direction of the shaft (36). The cables (33) are connected to the fixed bearing (341 ). Accordingly, although the shaft (36) rotates, the parts of the cables (33) outside the hose do not rotate, thus preventing the cables (33) from becoming entangled with each other.

[0038] The surface cleaning system (10) includes at least one control unit. The control unit provides the control of the elements in the surface cleaning system (10). However, the surface cleaning system (10) includes at least one image detection unit (40). Said image detection unit (40) is associated with the control unit. The image detection unit (40) analyzes an area where the wastes are located in the area to be cleaned and detects the spread of the wastes there. Therefore, the image detection unit (40) may contain at least one camera. The control unit, on the other hand, ensures the movable arms (30) are to have the appropriate opening depending on the information received from the image detection unit (40). Thanks to this embodiment, the surface cleaning system (10) of the invention ensures the wastes on the sea surface to be collected effectively with a compact structure. In order to achieve this, the movable arms (30) are unwrapped by the rotation of the pulley (35) and extend to the area where the waste is located, and when they surround the area by being guided by the drive elements (322), the locking motor (324) locks the hook (323) on one arm to the other. Thereafter, the pulleys (35) start to rotate in an opposite direction. Consequently, the interlocked guide ends (32) move towards the main body (20) and the collecting port (21 ). Meanwhile, the wastes between the collecting port (21 ) and the movable arms (30) are pushed by the flexible body with a sweeping motion, and the wastes enter the chamber through the collecting port (21 ).

[0039] In the surface cleaning system (10), the flexible bodies (31 ) of the movable arms (30) may be advanced to the desired area on the sea surface smoothly, thanks to the structure with drive elements (322) and floats (325) at the guide end (32). The floats (325) hold the guide end (32) on the sea surface, while the drive elements (322) guide the guide end (32). As shown in the figures, in the preferred embodiment, each movable arm (30) contains two floats (325). In this way, the guide end (32) may stand and be advanced more stable on the sea surface.

[0040] The image detection unit (40) allows the surface cleaning system (10) to operate autonomously, while the wired (33) drive structure reduces the cost of the system and provides an uninterrupted, efficient guidance. The anti-entanglement bearing (34), which prevents the cables (33) from becoming entangled, prevents the cables (33) from being damaged during the operation of the pulleys (35).

[0041] The scope of protection of the invention is specified in the attached claims and cannot be limited to what is explained in this detailed description for the exemplary purposes. That is because it is clear that a person skilled in the art may represent similar embodiments in the light of what has been explained above without departing from the main spirit of the invention.
