Description

Clamping parts for float tubes.

Description of the invention

The Object of the present invention "Pieces of clamp for float tubes ", as the name implies, It consists of a series of parts to hold and keep aligned the float tubes used in Aquaculture facilities Marina, whose diameter can range between 20 and 50 cms.

Since Polyethylene has a large chemical resistance to the action of seawater and is waterproof, most of the floating structures that are designed for the Marine aquaculture, whether for fish or for bivalve molluscs, are based on HDPE (High Density Polyethylene) tubes, especially in the case of spaces exposed to temporary (offshore). These tubes are welded forming straight lines from which hang the ropes with the crops (mollusks), or closed lines of which The nets hang for the fish cages.

To increase the weight that can support these Float tubes are arranged two and up to three lines in parallel, held by sturdy and rigid L-shaped pieces, manufactured by rotational molding in HDPE. These pieces are called "Brackets" and have at their base two or three holes aligned and parallel where the pipes run. "Brackets" go located approximately every three meters so that they hold the tubes and hold them together and parallel.

Despite the great strength and rigidity of "Brackets", these get to break due to the effort that they are subjected by the waves that move the float tubes, especially in temporary situations.

Moreover, the technology of manufacturing parts Rotomoulding plastic is not the safest when mechanical resistance requirements are high, since the mass of the product may present internal cracks and lack of compaction

We must also mean that more and more look for stronger floating structures, for example to use them as barriers, to reduce sea currents and waves and Protect crops better. In these cases you have to go to structures in steel, more expensive in construction and maintenance, since to hold more than three tubes with "Brackets", manufactured by rotational molding, It is not realizable.

A technology to manufacture plastic parts, which does guarantee a good compaction and therefore the consistency in the quality and mechanical resistance of the piece is the Injection Molding, but the design and size of "Brackets" to hold the tubes advised against it, because of its high cost

The present invention has solved the problem of the design in an original simple way, through four pieces that fit together in different ways to hold the tubes floats without limitation of their number or assembly or position.

These four CLAMPING PARTS, to which we will call STAR, "L" CLAMP, "U" CLAMP and "T" CLAMP, have common characteristics that we will describe below, and that allows them to be coupled by screw and nut, making it possible, by repetition and combination, the formation of float tube lines without number limitation

The four CLAMPING PARTS are manufactured in HDPE, with Injection Molding technology, which guarantees a well compacted and seamless dough. They also wear armor interior with steel rod (metallic insert) that attached to a cross rib system, ensures mechanical resistance to the most demanding sea conditions.

Description of the drawings

Fig. 1 shows Front and Profile the piece called STAR .

It is made of HDPE (High Polyethylene Density), with Injection Molding technology. Consists of four equal arms, arranged in a cross, that can support or hug four tubes (4), as indicated in the drawing Fig. 1.

At the ends of the four arms, as well as in the center of the piece there are identical circular holes (1), which allow coupling with other stars or with other fasteners, by screw and nut.

In all its surface a series have been arranged of straight and crossed nerves, marked with (2), to give resistance. This drawing of nerves is identical on both sides.

The piece is totally symmetrical with respect to plane that divides it into two parts of equal weight, be the middle plane which would give us two full stars, but with half the thickness,  like the cutting piano that goes through the center of the vertical axis or Horizontal would give us two half stars.

In the middle central plane of the STAR, in its interior, completely covered by the injected HDPE, we have introduced metal inserts of steel rods (3) that surround and join the five holes, giving them great cohesion and resistance.

Fig. 2 shows the Front and Profile the "L" CLAMP part .

Manufactured in the same way as the STAR, its mission is to attach a float tube to any of the other PARTS CLAMPING

It consists of two arms of equal shape and length L-shaped, at whose ends and center there are holes identical circular (1) that allow the coupling with the other CLAMPING PARTS, by screw and nut.

It also carries the design of nerves (2) to give it resistance and the inner metal insert (3) that surrounds and connect the three holes (1).

It is also symmetric with respect to the middle plane center that divides the piece into two equal parts with half of thickness.

Fig. 3 shows the "U-CLAMP" part of Front and Profile .

Everything said for the previous piece (Bra in L), in terms of manufacturing, design, symmetry ... is valid for the "U-Bra", with the difference that it embraces, holds two tubes, when coupled with the STAR or with the next piece (T-bra), instead of a single tube, as is the case with the piece of fig. 2.

Fig. 4 shows the "T-CLAMP" part of Front and Profile .

Everything described for the previous pieces is Transferable to this piece. The T-Bra also embraces two tubes, but it can have other functions such as handrail to hold nets in a fish cage.

To make it easier to understand the novelty that means these pieces in relation to the subjection of float tubes we have drawn schematically in the figures 5 and 6 two possible assemblies that today are not realizable with the Current rotational molding brackets:

Fig. 5 represents the schematic section of a fish cage with four tubes and railing and Fig. 6 the schematic section of an assembly of eight breakwater float tubes .

As seen in these schematic drawings, the composition of the four CLAMPING PIECES, which are enshrined by screw and nut, through its matching holes, it allows us all float tube constructions without number limitation or positioning.

Description of a case study

The novelty of the invention and its great practical sense lies in its unlimited possibilities of being able to join the float tubes used in Marine Aquaculture in number and arrangement, vertical or horizontal, so that the load they have to bear will no longer be an obstacle.

If it is FISH CAGES, they can be done larger diameter or with double and safety nets, since we can have more buoyancy by placing four, five ... or lines of float tubes that are necessary.

If it's LONG-LINES of where oyster and mussel crops are hung we can increase the load by increasing the number of tubes.

Also with these CLAMPING PARTS you can build floating structures like platforms, break currents and breakwaters that until now were only reserved for metal floats whose cost is much higher.

And all without limitation as to conditions that the sea can present to us, since the PARTS OF SUBJECT have been designed to withstand the storms, being Made of High Density Polyethylene, by Molding by Injection, with an inner metal armor and a system of nerves that makes them virtually unbreakable.

In summary, the legislator states that so that an invention can be accepted and protected as a "model of utility "must be a practical and useful novelty, not a  simple modification on something already existing, and indeed, as we have been able to describe, these inventions are given conditions, not currently existing CLAMPING PARTS of Float tubes, manufactured in HDPE by Injection Molding, or that allow so many possibilities of joining float tubes without number limitation, neither in height, nor in width, and all this by the simple combination of four pieces that are joined by a screw and nut.

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