Description

Float tubes for the construction of articulated structures for marine aquaculture.

Description of the invention

The object of the present invention, as expressed in the statement of this specification, consists of " Tubes-Floats for the Construction of Articulated Structures for Marine Aquaculture ".

The growing importance of the marine aquaculture for the production of bivalve molluscs and different kinds of fish as an alternative to fishing extractive

The estuaries and protected natural environments of Temporary are used for this purpose, having reached a supersaturation, with serious pollution problems that they also affect the crops themselves.

Therefore, solutions are sought that can lead these offshore holdings, which implies solve the main problem of resistance to storms.

In the case of mussel farming, the Traditional "wooden bats", for their rigidity, are not suitable to withstand strong waves. Solutions have been sought from long lines of floats, attached by their ends to the background for two "dead", from which they hang vertically crop lines or structures similar or more complex submerged at a certain depth to decrease the effect of the waves.

The solution to submerge the crop to reducing the effects of the storm poses technical problems important when modifying the buoyancy of the system, which must rise for crop harvesting (water displacement of floats by compressed air, increase of floats ... etc.).

As for the cages to raise the fish, the general solution is based on welded PE pipes forming a long closed line from which hang the networks that They form the cage.

These cages are usually made up of two parallel lines of welded float tubes throughout their length which are held by very robust pieces made of plastic by the rotational molding technique that has an "L" shape Tied up the net.

This piece in L that rigidly fixes the tubes floats must withstand all the swell action and sometimes it breaks, despite its robustness, creating a serious problem of maintenance of the network enclosure.

On the other hand, the advantages of a Offshore platform are obvious:

\ ding {51}

One more mix is produced intense along the water column, so the oxygen concentration conditions are generally higher and The waters are cleaner.

\ ding {51}

The concentration of contaminants, pesticides, etc., can be considered to be virtually non-existent

\ ding {51}

The pellets produced by mussels, will have a greater dispersion in oceanic waters, since long distances will be transported while they settle to the bottom.

\ ding {51}

Outside the coastal areas protected nutrient enrichment because of Human activities is less. Therefore, it is foreseeable that chances of a phytoplankton proliferation occurring minors

For all these reasons, we have invented float tubes for the construction of floating structures and which we will describe below, which seeks to solve the problems of resistance to storms, without incurring serious technical complications such as the solution of submerging them, or excessive costs.

On the other hand, our " Articulated floating structure, in the form of a ladder ", allows a horizontal cultivation of bivalve molluscs, which is also a reason for claiming.

The present invention starts, as we have announced, of rigid float tubes (Fig 1), made of plastic (HDPE), with a resistance capable of withstanding internal pressures of 10 Kgs / cm, and of a diameter that will range between 250 and 500 mm. and a variable length (maximum that allows a transport by truck), in whose ends the " closing pieces " are welded (Figs 2 and 3) whose function is triple:

\ ding {51}

Make the tube airtight (float)

\ ding {51}

Allow the union with other tube-floats both longitudinally and transversely, forming: lines, T's or crosses.

       \ newpage
    

The joints between the tube-floats are made in a simple and fast way, by means of a single screw and nut designed for this purpose.

It is important to note that the design of these " closure pieces " (Figs 2 and 3) allow the attached float tubes to remain all in the same plane (waterline) without overlapping each other (Fig. 4 and 5).

\ ding {51}

Tie the protective nets to the " closing parts "

The advantages of our system are:

\ sqbullet

The union of tubes in one way so simple (just a screw and nut) allows an installation Fast and easy and inexpensive repairs.

\ sqbullet

The articulated form of lines allows to absorb the efforts that the Wave movement exerts on the structure.

\ sqbullet

You can modify the buoyancy of the system by short sections according to needs

\ sqbullet

For certain crops we can make a stair-shaped structure with two parallel lines of great length, crossed by perpendicular reinforcement lines by way of rungs of a ladder.

From the 2 long lines the crops can be hung horizontally, being protected in this case by networks that are subject to the " closing pieces " (Fig. 2.1).

Description of the drawings

Figure 1 presents the piece in 3 dimensions already finished and consisting of:

HDPE tube of high resistance (Fig. 1.1), manufactured with extrusion technology, capable of supporting a internal pressure of 10 kg / cm2. The diameter can range from 250 mm to 500 mm.

In both ends of the tube the " closing pieces " are welded in their 2 versions: Fig. 2 (longitudinal coupling) and Fig 3 (transversal coupling).

These parts are manufactured in HDPE with the injection molding technology, being very robust and being designed to withstand an effort of 5,000 kg. Take 2 vertical arms (Fig, 2.1) to tie the protection nets in necessary case.

The coupling between the different tubes Floats are made with a large screw and nut that are reinforced with a steel core and made of plastic HDPE by injection molding. These elements are not considered. object of the invention.

Figs. 4 and 5 tell us the detail of how two longitudinal and two transverse tubes are joined leaving all In the same plane.

Fig. 6 and 7 schematically indicate the construction of a ladder platform with cultivation horizontal.

Description of a case study

The utility of the invention and its great meaning Practical lies in its flexibility and its extreme ease to build marine aquaculture structures with guarantees of resist strong storms.

Indeed, if it is a closed cage for sustain a network where to grow fish, the producer or installer will join the float tubes longitudinally until Get the way he wants.

If it is circular you can cross the circumference With two diameters to maintain the circular position.

But you can also similarly make square or rectangular cages, independent or interconnected for different species or sizes

In the case of bivalve mollusc culture, the Producer can design his own crop: from a single line long to hang the growing ropes (French system, Italian), to the "smart-line" system (Norwegian), where the strings are replaced by meshes.

But with our articulated float tubes, a ladder structure can also be made, which allows place the crop horizontally (Fig 6 and 7), which is also a novelty that we want to claim, for its advantages of homogeneity of nutrients and light, which do not occur in the crop vertical.

In summary, the legislator establishes that for an invention to be accepted and protected as a "utility model" it must be a practical and useful novelty, not a simple modification on something already existing, and indeed, as we have been able to describe, it In our invention these conditions exist, there is currently no structure for marine aquaculture with ladder -float tubes with horizontal cultivation, or float-tubes with the characteristics we have invented, capable of forming articulated floating structures, both in the sense longitudinal as transverse, keeping all the float tubes the same plane or waterline, and being joined by a single screw and nut.

For all this, we want to explain that the exclusive exploitation privilege requested will fall on the following claims.
