DESCRIPTION

DEVICE FOR CLEANING SEA WATER

OBJECT OF THE INVENTION

The present invention relates to a device for cleaning sea water.

BACKGROUND OF THE INVENTION

The pollution of marine waters by plastics is an undeniable fact, which is causing enormous damage to life as it enters the food chain by being decomposed into smaller and smaller plastics and microplastics and being ingested by fish, chelonians and mammals marine, in such a way that the use of plastics is even being limited and / or prohibited by administrations.

Despite this ban, a large amount of plastics are already in the sea, and need to be removed. The problem is that adequate means are not available for this, a drawback that is solved with the device of the invention.

DESCRIPTION OF THE INVENTION

The device for cleaning seawater of the invention comprises:

-an autonomous unmanned floating stand,

-a set of purification elements that comprise first submerged filters, vacuum cleaners by venturi effect associated with blowers to force a suction of sea water through said first filters, and the corresponding conduits), and

-a control unit associated with the blowers.

In this way, the floating support can be navigating or anchored autonomously (without crew) in areas that are known to be contaminated with plastics and microplastics, carrying out continuous cleaning and purification in the area near the surface, which is precisely where it is most they accumulate these residues and where they are most ingested when they are confused against the light with dams. It also filters any other type of polluting residues. The suction by venturi effect is carried out by blowing the blowers, which also improves oxygenation and purification of the same, achieving an additional unexpected effect consisting of a gentle aspiration of sea water, much softer than that carried out by any pump, which is more selective with microplastics, preventing small fish from being aspirated or any other fauna.

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

The device (1) for cleaning seawater of the invention comprises:

-a floating stand (2) autonomous unmanned,

-a set of purification elements comprising first submerged filters (5a), vacuum cleaners (66) by venturi effect associated with blowers (44) to force a suction of seawater through said first filters (5a), and the corresponding conduits (45) (which include a return (45a) of the treated water to the sea), and

- a control unit (10) associated with the blowers (44).

In addition to the above, the device (1) may comprise (or not) pumps (6), suction intakes (3) and discharge intakes (4) of sea water, to direct the water towards second filters (5b), which are shipped on the floating support (2), to work in waters with a higher degree of plastic pollution.

The invention also provides for the provision of rechargeable batteries (8) to power the control unit (10), the blowers (44) and pumps (6), where appropriate, and photovoltaic plates (11) for recharging the batteries. batteries (8), increasing their autonomy.

The floating support (2) can lack propulsion, being able to be anchored or navigate at the mercy of the currents, or it can comprise an autonomous unmanned vehicle, with autonomous means of movement and navigation; the control unit (10) then comprising a navigation control associated with said autonomous means of movement and navigation. The autonomous means of movement and navigation can include, at the less, an electric propeller (7), and rudders (9) or flow directional variation elements fed from the batteries (8). The navigation control of the control unit (10) may comprise a satellite navigation device (100) to program a route and that can follow it autonomously, and in addition or alternatively a signal receiver (101) of a remote control (102 ) management.

The different interior elements of the floating support (2) can go under a canvas (20), leaving the photovoltaic panels (11) on the outside of it.

Having sufficiently described the nature of the invention, as well as the way in which it is carried out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are susceptible to detailed modifications as long as they do not alter the fundamental principle.
