DESCRIPTION

Protection device for Bouchot mussel breeding piles

FIELD OF THE INVENTION

The present invention relates to a protection device that is installed in Bouchot mussel breeding piles to protect them from predators.

STATE OF THE TECHNIQUE

Bouchot mussels transported by breeding piles are exposed to multiple predators. To protect them, there are already, according to document WO 2008/142215, protection devices composed of modules that slide over the batteries. These modules are grid-shaped and surround the growth and development space of the mollusks.

However, the installation of these basket modules is not easy due to the large number of modules that must be installed and then removed to collect the molds.

There is also a device called a "fishbowl cone" shaped like a workshop lampshade, which consists of two superimposed cones with a curved generatrix: a relatively narrow upper cone and a much widened lower cone. Apart from the fact that the cone only fits one size of pile and that you need as many types of cone as there are pile sizes, it does not offer sufficient protection to the mussels. The large legs of crustaceans can penetrate the cone by hooking on the lower edge of the lower cone.

PURPOSE OF THE INVENTION

The objective of the present invention is to develop a protection device for mussel breeding piles that is simple and economical to manufacture, quick to install and dismantle and, at the same time, very effective in protecting the mussels in the mussel breeding piles. breeding.

DESCRIPTION AND ADVANTAGES OF THE INVENTION

To this end, the object of the invention is a protection device for a Bouchot mussel breeding pole, characterized in that it has a cap structure composed of a cap in the shape of a truncated pyramid that exceeds its edge in the form of a truncated conical skirt, having the truncated pyramid an open top and facets, and a rectangular and in particular square section, the truncated pyramid being longitudinally subdivided by means of at least one breaking groove originating at the edge of the open top, the truncated pyramid being attached to the conical skirt by means of a joining band without a sharp edge in the course of the geometric intersection of the truncated pyramid and the conical skirt, the truncated pyramid is subdivided by cuts that meet its outer edge, in order to open from of the vertex and adapt the pyramid to the cross section of the pile in which the protection device is installed.

This protection device has the advantage of being very easy to manufacture, install or remove. This shape easily adapts to various types of piles, of different sections and allows effective protection of the mussels raised in the pile, against predators, in particular crustaceans.

The surface covered by the protective device is important because it is not a grid, but rather a relatively continuous surface. Despite the sail-shaped surface of the protector, its structure gives it the necessary rigidity to protect the mollusks well despite the repeated and sometimes violent movement of seawater over and between the protectors.

This strength is especially reinforced by the facets of the truncated pyramid, which are joined by curved surface edges, thus forming a three-dimensional reinforcement of the edges of the truncated pyramid.

Particularly advantageously, the facets are joined by ridges arising from the substantially punctual union of the upper faces of the facets that form the open upper part of the pyramid, extending from this union by a conical sectoral surface to the side of each facet. at the junction with the skirt. This facet shape Combined with the ridges it provides a rigid but adaptable structure for the cross section of the brood piles.

In another advantageous feature, the path of the tie band followed by the tie band is a three-dimensional geometric curve composed of concave arcs forming the underside of each facet, these concave arcs being connected by convex arcs at the bottom of each. truncated surface that forms the edge that connects the two corresponding facets.

This three-dimensional design develops a rigid peripheral surface at the junction of the truncated pyramid shape and the truncated skirt, to which the top of the truncated pyramid and the peripheral part of the truncated skirt are flexibly articulated.

The elasticity of these two parts, one due to its adaptability to the pile and the other due to participating in the movement of the water, guarantees the good behavior of the device and its reliability.

According to another characteristic, at least two opposite facets of the truncated pyramid, in particular all the facets or at least two edges and in particular all the edges, are provided with a breaking opening. In other words, at least one or two opposite facets of the truncated pyramid or all facets of the truncated pyramid are provided with a breaking opening, or at least one breaking opening is provided on one or two opposite edges or on all edges of the truncated pyramid. In this way, the cross section of the protection device in contact with the periphery of the pile can be adapted to different cross sections of the pile by uniformly distributing the forces and elasticity of the protection device on its periphery, without stressing a single part. Of the device.

Another feature is that the breakage space is closed by breakable bridges to adapt the contact cross section of the protection device to the stack and keep the device firmly in the stack.

In a further feature, the truncated pyramid is provided with peripheral reinforcements along at least one section of the truncated pyramid between its open top and its base, which peripheral reinforcement passes through the fracture grooves with reinforced bridges.

As an additional feature, the skirt has cutouts attached to its outer edge to adapt its flexibility to the movement of water around the pile.

Another characteristic is that the facets are formed by two flat parts joined in the center of the facet by a truncated conical segment.

In another feature, to facilitate the packaging and transportation of the protective devices, the lower part of the skirt is provided with triangular support sheets distributed in a circle with a rounded vertex to serve as a support for stacking the protective devices and to support the skirt of the protective device at the base of a stack of protective devices on a sleeve.

In this way, the pile is supported on the support, preferably in the form of a cylindrical sleeve, by means of the lamellae that are located near the junction between the skirt and the truncated pyramid of each protective device.

In other words, the weight of the stacked protective device does not rest on the contour of the skirt at the base of this stack of protective devices.

DESCRIPTION OF THE METHODS OF APPLICATION OF THE INVENTION

According to an embodiment shown in Figures 1 to 4, the subject of the invention is a protection device for breeding mussels on stilts. The protection device has the shape of a hat whose perforated lid allows it to be hooked on a pile represented by its vertical axis ZZ.

The protection device 100 consists of a truncated pyramid 1 with a polygonal section similar to that of a square, with the open upper part 1a and connected at its base 1b to the edge of this hat shape; this edge is formed by a conical skirt 2. The protection device 100 has a rotationally symmetrical shape around the ZZ axis.

The protection device 100 consists of a truncated pyramid 1 of polygonal section, with an open upper part 1a and connected by its base 1b to the edge of this hat shape; this edge is constituted by a conical skirt 2. The protection device 100 preferably has a rotationally symmetrical shape around the ZZ axis showing the stack it is intended to equip and protect.

The base 1b of the truncated pyramid 1 with an open top 1a is joined to the truncated skirt 2 by a joint or connecting band 3 that follows a connecting line 31 corresponding to the geometric intersection of these geometric shapes in the form of a network of a molded or injected plastic material.

The truncated pyramid 1 of polygonal section has, in this example, a rectangular section, in particular square. The facets 11 are joined by edges 12 with a rounded section, forming conical sections that widen from the upper part 1a to the base 1b. The edges 11 are preferably subdivided in the center by a break line consisting of a slit 13 that begins above the base 1b and opens at the upper edge of the vertex 1 a; The slot 13 is interrupted by bridges 131 connecting its two edges 13a, 13b. These bridges 131 can be broken to allow the opening of the slot 13 and increase the entrance section of the pyramid 1' which is limited by the section of its vertex 1a, and adapt to the section of the pile while remaining elastically applied against the pile.

The slot 13 preferably stops at a certain height above the splice band 3 to prevent the opening of the slot 13 from reaching the splice band 3.

Preferably, each facet 11 is subdivided by a breaking groove 13 into two parts of this facet 111, 112. The dihedrals formed by the two parts 111, 112 of two adjacent facets 11, connected by an edge 12, are thus rigid dihedrals; The widening of the edges 13a, 13b of the breaking grooves 13 that open in a V shape from the small base 1a is possible mainly without deformation of the area of the skirt 2 connected to this dihedral formed by the parts 111, 112 , 12.

The inner surface of the truncated pyramid 1 has peripheral reinforcements 14 located at different levels. These peripheral stiffeners 14 have reinforced bridges 141 that traverse the break grooves 13 to form reinforced lines that locally stop the opening of the break groove 13 at different levels, for example, three levels corresponding respectively to increasing opening sections of the truncated pyramid. 1.

The peripheral reinforcements 14 are, for example, raised beads. The inner surface of the facets 11 also has hooking points 15 consisting of notch-shaped reliefs to favor the hooking of the protective device 100 in the best possible way, thus avoiding a smooth inner surface of the pyramid.

The relief of the inner surface of the truncated pyramid 1, that is, the peripheral reinforcements 14 and the attachment points 15, separate the truncated pyramids from two protective devices 100 stacked on top of each other in a stowed state; This separation prevents the two surfaces from sticking together and subsequently complicating their separation when unpacking.

The conical skirt 2 is flared without edge but with substantially radial notches 21 to give it flexibility; The smooth edge 22 of the edgeless skirt 2 prevents any point or area for crustaceans to catch on the protective device 100.

The joint 3 between the truncated pyramid 1 and the skirt 2 follows line 31, which is the geometric intersection between the prismatic surface constituted by the truncated pyramid 1 and the conical surface of the skirt 2. The joint 3 is a band with a rounded or curved section that follows the large base 12 according to line 31. It should be noted that this line 31 is a three-dimensional line that avoids a line in a plane between the base 1b of the truncated pyramid 1 and the conical skirt 2 and which would be a weakened or fragile contour due to the repeated movements caused by the passage of water around the pile.

The joint 3 thus forms a band composed of four arcs 32 at the base of each facet 11, connected to the convex curvature 33 of the truncated conical shapes of the base 121 of each edge 12.

The connection area 3 thus created constitutes a framework, stabilizing the shape of the device 100 while leaving it elastic and adaptable to the section of the stack along the edge of the upper part 1a of the truncated pyramid 1 and to a certain flexibility of the skirt. 2 resulting from its cuts 21 and also from the deformations produced by the back and forth movements of the water.

The narrowest non-expandable inner section of joint 3 is larger than the largest section of a pile.

Truncated pyramid 1 has a square cross section that best fits the rounded shape of a pile. However, this cross section can also be polygonal, for example with five or six sides; can be different from a square cross section depending on the cross section of any pile, which then fits better into a rectangle than a square.

Reducing the cross section of pyramid 1 to a four-sided cross section allows the facets 11, edges 12 and; The parts 111, 112 of the facet 11 joined to the segment 16' result in a pyramid with a rigid shape while having sufficient elasticity through the breaking edges 13 to fit firmly to the cross section of the piles.

Figure 1A shows in more detail the structure of a half pyramid 1, highlighting the shape of the facets 11, which are flat on both sides 113, which gives them a trapezoidal shape at the top of the facet that continues with parallel edges. .

This figure 1A shows three peripheral reinforcements 14a, b, c at three levels defining three different sections to elastically accommodate three pile sections.

The bridges 131 of the breaking grooves 13 are replaced or completed in the peripheral reinforcements 14a, 14b, 14c by reinforced bridges 141 to constitute breaking points that offer more resistance than the other bridges 131 in order to mark the corresponding section of the pyramid 1 in each peripheral reinforcement 14.

The sides 13a, 13b of the breaking grooves form the geometric line of connection with the edges 12, highlighting the conical sector shape of the edges 11, which start from the straight contour of the vertex 1a and widen clearly downwards.

The lower contour drawn in Figure 1A is a simple cut in the drawing and does not represent the part of the actual path 31 of the contour of the base of the truncated pyramid. This contour is shown in the axial section of Figure 4.

Figures 1 and 2, seen from below, show the lines of the fixing points 15 on the inner surface of the facets 11.

Figures 3 and 4 show the overall shape of the protection device 100 in front view and in half section and, in particular, highlight the highly accentuated three-dimensional shape of the connection 3 with the concave arches 32 of the base 1b and the arches convex edges 33 of the conical edges 12, as well as the strong taper of the skirt 2.

According to Figures 5 and 6, the second embodiment of the protection device 100' has the shape of a hat, whose perforated cover allows it to be hooked on a post represented by its vertical axis ZZ, generally a post with a square section, for example with a 10 x 10 section. cm.

The description of this second embodiment, which corresponds in many respects to that of the first embodiment described above, will be completed only by the variants.

The protection device 100' consists of a truncated pyramid 1' of polygonal section similar to a square, with the open upper part 1a' and joined at its base 1b' to the edge of the plug formed by a 2' conical skirt. The protection device 100' is rotationally symmetrical with respect to the ZZ axis.

The base 1b' is joined to the conical skirt 2' by a connecting band 3' that follows a connecting line 31' corresponding to the geometric intersection of these geometric shapes similar to a veil of molded/injected plastic material.

The truncated pyramid 1' of polygonal section has, in this example, a square cross section which is clearly shown in Figure 5, since the edge of the vertex 1a' is flat, while the cross section represented by the base 1b' is the intersection of the truncated pyramid 1' and the truncated skirt 2', which is a three-dimensional intersection curve.

The faces of the pyramid are 11' planar facets with a frustoconical segment in the center. The facets 11' are joined together by edges 12' with a rounded section, forming conical sections that widen from the vertex 1a' to the base 1b'. The edge of the vertex 1a' in the part of the truncated conical segments 16' has a claw 161' for fixing to the post.

The base of the truncated cones 16' is preferably closed by a lid to prevent the ascent of predators without affecting the mechanical function of the truncated cones 16'.

The edges 12' are subdivided in the center by a break line consisting of a slit 13' that begins above the base 1b' and opens at the upper edge of the vertex 1a'; The slit 13' is interrupted by bridges 131' connecting its two slit edges. These bridges 131' can be broken to open the slot 13' and increase the entrance cross section of the pyramid 1' (limited before breaking by the cross section of its vertex 1a'), and to adapt to the cross section of the pile remaining resiliently pressed against the pile. Advantageously, the slot 13' is interrupted at a certain height of the base so as not to join the joint 3' and thus reinforce the support of the post.

Each facet 11' is divided by the conical segment 16' into two facet parts 111', 112'. The dihedrals formed by the two parts 111', 112' of two adjacent facets 11', Connected by an edge 12', they are dihedrals that open in a V shape from the small base 1 a' and without deformation of the skirt area 2'.

The conical skirt 2' is flared with a smooth edge 22' without flange but with substantially radial notches 21' to give it flexibility; The smooth edge 22' prevents any snagging point or area for crustaceans that could climb the protective device 100'.

The connection 3' between the truncated pyramid 1' and the skirt 2' follows the path 31', which is the geometric intersection between the prismatic surface constituted by the truncated pyramid 1' and the conical surface of the skirt 2'. Joint 3' is a band with a rounded or curved section that follows the large base 1b' along line 31'.

The joint 3' forms a band consisting of four arcs 32' at the base of each facet 11', connected to the convex curvature 33' of the base of each edge 12' through the smooth curve of the parts 111', 112 'facet 11'.

The joining area 3' thus created constitutes a framework that stabilizes the shape of the device 100', leaving at the same time elasticity and adaptability to the section of the stack along the edge of the upper part 1a' of the truncated pyramid 1' and a certain flexibility of the skirt 2' resulting from its cuts 21'.

The narrowest non-expandable inner section of the joint 3' is larger than the largest section of a pile.

Truncated pyramid 1 has a square cross section that best fits the square shape of a pile. However, this cross section can also be polygonal, for example with five or six sides; may be different from a square cross section depending on the cross section of any pile that fits a rectangle better than a square.

Reducing the cross section of the pyramid 1' to a four-sided cross section stiffens the facets 11' and opens the edges 12'; the parts 111', 112' of the facet 11' attached to the segment 16' stiffen the pyramid while leaving sufficient elasticity to through the breaking edges 13 to fit tightly to the cross section of the piles.

The cross-sectional view of Figure 7 and its enlargement in Figure 7A according to the axial section plane VN-VN of Figure 6 show the stacking of two protection devices 100'.

In the vicinity of its connection 31' with the trunk of the pyramid 1', the lower part of the skirt 2' has support sheets 17'. These triangular sheets 17' have a lower side 171' slightly inclined towards the horizontal plane HH, which makes it possible to stabilize the stacking of several protection devices 100' on a storage support in the form of a cylindrical sleeve 4' with a diameter equal to that of the circle. which passes through the point of union of the sides 171' with the petals 23' formed by the notches 21' of the skirt 2'.

The sides 171' of the support sheets 17' therefore lie on an inverted conical surface which is located at the upper edge of the support 4'.

The top 172' of these sheets 171' is rounded to rest securely against the top of the skirt 2' of a device 100' already placed in the stack.

For stability reasons, the support sheets 171' are evenly distributed and each located in the center of a respective petal 23'.

In this way, the stacking is carried out without surface contact between the successive devices 100' and without the device 100' located in the lower part of the stack resting on its skirt other than under the effect of its own weight. In this way, the devices 100' can be stacked and palletized very densely without risk of deformation.
