ES2270701B1 - CIRCULAR OR ELIPTIC BATEA FOR BIVALBOS BREEDING WITH RADIAL FLOATING SYSTEM. - Google Patents

Abstract

Bat formed by concentric and equidistant circular crowns (1) of polyethylene tube from which the culture ropes will hang; these crowns will be held together thanks to the fact that under these two types of radially arranged floats will be arranged: primary floats (2) that will give buoyancy to the system and serve as mooring points for the bat and docking of auxiliary ship, and secondary floats (3) (smaller than the primary ones) that will act as reinforcement of the previous ones.

Description

Circular or elliptical bat for bivalve breeding with radial flotation system.

(NOTE: when "open sea" is cited it will be done reference to an area that is approximately one mile away from the coast and at a depth ranging between 30 and 50 m)

Technical sector

This patent belongs to the scope of the aquaculture, a sector dedicated to the cultivation of marine species of interest for man.

State of the art

At present, for the breeding of bivalves, the most widespread device is the traditional bat, consisting of large floats of variable number on which a eucalyptus wood structure as a grid of which Hang the ropes for cultivation.

One of the inconveniences of the bats traditional, is the use of wood for construction of the grid due to deforestation of national forests of recent times, resulting in a difficulty in Search for large eucalyptus with optimal characteristics. At the same time, mention that the duration of this type of material in The marine environment is approximately 10 years old. It is also necessary that there is a considerable distance between it and the surface marine, since organisms found in water damage the wood in a shorter period of time.

Traditional trays, being built for the most part wood, they are not able to withstand existing in the open sea, so it is mostly they have located in sheltered areas such as the Galician estuaries (where the administration no longer grants licenses), with water rich in nutrients but already very worn in recent years due to the large number of existing polygons, which entails a high growth rate but lower than what would occur in open sea.

On the other hand, for fish farming (tunas, sea bream, sea bass, etc ...) in the open sea in recent years, it have been using circular structures manufactured with polyethylene with which excellent results are being achieved of useful life of the facilities and low maintenance.

Description of the invention

The bat built by:

-

Crowns of polyethylene tube. Located on radial, primary and secondary floats.

-

Primary radial floats. Primary metallic and polyethylene structures * treated with anti-corrosives whose function will be to maintain the different tube crowns in position and that contribute to the flotation of the artifact. In addition, they will serve as a mooring point for the realization of the anchor of the "bat" and the work boat. They will divide the  tubular crowns in "sectors",

\ text {*}

When this report cites "metallic and polyethylene structures" means: that they can be totally iron, totally polyethylene, or Polyethylene parts with reinforcements and metal hardware. This it expresses itself this way, because the inventor has developed all three options, being able to choose between any of the three depending on of the occasion and preferences of the client who orders the bat.

-

Secondary radial floats. Secondary structures formed by polyethylene parts and metallic (smaller than the previous primary structures), that will act as reinforcement of the previous ones. They will be willing between two primary structures and like these, they will divide the circular crowns in "sectors".

-

Railings. They will be chains, ends or Similar and its installation is optional. Iran located to greater height that the crowns of polyethylene tube and moved towards the interior or exterior thereof, in such a way as to facilitate step over these tubes and allow the work of Work is done safely.

-

Gateways (optional). They would be available alternatively surface walkways anti-slip between polyethylene pipes for facilitate work tasks. They would be manufactured in polyethylene or other material.

-

The cultivation ropes These can be hung both from the crowns of polyethylene pipes, such as radial floats, whether primary or secondary

-

Nets anti-predators (optional). Touring the interior and exterior perimeter of the artifact, would be hung both in the inner limbs as in the outer limbs of the primary and secondary radial floats networks that would protect crop ropes from predatory attacks sailors These networks would have a counterweight on their part lower so that they remained extended.

This structure (bat) has a large strength and flexibility, being possible to install in areas of open sea, since it will be able to resist the envy of the sea and warp adapting to the waves, thus contributing to facilitate the clamping of the mussel on the growing ropes. It is also equally suitable for estuaries, provided that the size and anchoring.

Brief description of the drawings

Description of an embodiment of the invention

The invention is formed by:

-

Five crowns of polyethylene tubes (1) of 200 mm outside diameter. It starts from an outer crown of 48.5 m in diameter from which, in an equidistant way, the remaining ones will be placed. These crowns will be located on radial floats.

-

The polyethylene tube crowns will maintain their position by 8 primary metal and polyethylene floats (2), arranged radial shape In addition, these floats will serve as a mooring point for the realization of the anchor of the "bat" and the ship of job.

-

It will have 64 secondary floats, arranged radially, basically made with 400 tubes mm diameter of polyethylene (3) that will act as reinforcement of the primary floats.

-

The railings will be constructed with 40 mm composite stake diameter, (4). Iran located on the polyethylene crowns and displaced into or out of them, in such a way so that they facilitate the passage over these and allow the Work tasks are carried out safely.

-

Footbridges (5) with dimensions of 1700 x 500 mm made of polyethylene and with surface anti-slip. Its function will be to facilitate the movement in work tasks.

-

At traditional bivalve culture ropes (6), may be hung  both of polyethylene pipes and radial floats either primary or secondary.

-

Nets anti-predators (7). Touring the perimeter inside and outside the artifact, they would hang both on the inner extremities as in the outer extremities of the primary and secondary radial floats 60 mm nets Mesh light that will protect the crop ropes from attacks of marine predators. These networks will have a counterweight (8) in its lower part so that they remain extended.
