Definitions
- the invention relates to a floating protection system against jellyfish.
- the invention will find application in the protection of bathing areas.
- This solution has a complex structure that involves a high manufacturing cost and a high cost of assembly.
- installation and uninstallation are particularly difficult and time consuming.
- These disadvantages are all the more detrimental as the length of the bathing area to be protected is important.
- the present invention aims to improve the existing floating protection systems.
- a floating protection system comprising at least one float, a protective net acting as a barrier for jellyfish and / or pollution, the protective net being arranged in a manner to act as a sleeve enveloping the float.
- the protective net provides continuity of protection between the floats and the net. It thus offers a good efficiency.
- the assembly of the various elements can be carried out particularly easily.
- the claimed structure allows mounting by simply inserting the floats into the previously formed sleeve, or by forming the sleeve around the floats previously arranged in contact with the protective net. This simplicity of assembly also contributes to reducing costs.
- the floating protection system according to the invention may furthermore have at least one of the following characteristics: -
- the protective net has an upper portion having a first mesh size and a lower portion having a second mesh size, the first mesh size being smaller than the second mesh size.
- the first mesh size is between 1 and 8 mm 2 and more particularly between 1 and 5 mm 2 ,
- the second mesh size is between 1 and 2 cm 2 and more particularly between 1, 2 and 1, 8 cm 2 ,
- stop means prevent the floats from moving in the holding net
- fastening means making it possible to bond the protective net and the retaining net to another protection system or to an independent support of the protection system
- the net is arranged in such a way that the meshes have a limited deformation when transverse traction is applied to the system
- the system comprises a cord connecting the floats between them,
- the cord comprises stop means for limiting the translation of the floats along the cord.
- a floating protection assembly comprising at least two systems according to any one of the preceding characteristics and fixing means, the two systems being linked to each other by the fixing means.
- the invention provides a protection assembly comprising a system according to any one of the preceding characteristics and a guying system arranged so as to allow a temporary displacement of the floats and tending to keep the protective net in a substantially vertical position.
- a protection assembly comprising a system according to any one of the preceding characteristics, the assembly comprising a fish tunnel connected to the lower portion of the protective net intended to rest on the ground, the tunnel and the net protection devices arranged in such a way that fish can only pass through the protection assembly through the tunnel.
- FIG. 1 is a diagrammatic front view of an example of a protection system according to the invention
- FIG. 2 is a diagrammatic side view of an example of a protection assembly comprising a protection system and a guying system according to the invention
- FIG. 3 is a schematic perspective view of an exemplary tunnel for a protection assembly according to the invention.
- - Figure 4 is a partial view of a protection system having a net according to an exemplary embodiment
- - Figure 5 is a partial view of a protection system having a net according to another embodiment.
- the system comprises floats 2 and a protective net 3 connected to the floats 2.
- the protective net 3 is formed from a base piece of substantially rectangular shape, constituting a mesh and having an upper edge and a lower edge opposite the lower edge.
- the upper edge is fixed on the base piece so as to form a sleeve 33 extending over substantially the entire length of the latter.
- the fastening of the upper edge on the base piece is performed by conventional means including sewing or stapling.
- the system also comprises a ballast 6 attached to the protective net 3.
- the ballast 6 is fixed to the bottom edge.
- the ballast 6 has for function to bring the bottom edge to contact or at least towards the bottom during use.
- the floats 2 are housed inside the sleeve 33 and distributed over substantially the entire length of the latter. Their dimensions, their number and their material are chosen so as to ensure the flotation of the protection system 1 regardless of the length of the protective net 3 or the ballast 6 used.
- the protective net 3 extends between the floats 2 and the ballast 6 and defines a substantially vertical plane.
- the height of the protective net 3 is adapted according to the bathing area protected and is chosen so that the protection system 1 extends substantially from the surface of the water to the bottom.
- the mesh size of the protective net 3 is chosen to prevent the passage of jellyfish but allows the flow of water.
- the protection system 1 thus provides an effective barrier against jellyfish.
- connection between the floats 2 and the net is provided in a particularly simple manner. This simplicity makes it possible to reduce the number of parts and thus to limit the manufacturing cost.
- the mounting of the net can be ensured particularly fast and easy which also helps to limit manufacturing costs.
- this connection of the floats 2 and the net allows a quick and easy installation and uninstallation of the floating protection system. This advantage is particularly appreciable when the protection zone is extended or when the installation or uninstallation operations are carried out under difficult conditions. Furthermore, the protection system 1 according to the invention has a small footprint, which proves to be advantageous during storage, transportation or installation or uninstallation operations.
- the protection system 1 makes it possible to present a resistance limited to the current and the waves.
- the protective net 3 comprises an upper portion 31 and a lower portion 32.
- the upper portion 31 comprises the sleeve 33, and has a submerged portion of about 20 cm in height.
- the upper portion 31 has a first mesh size.
- This first mesh size is between 1 and 8 mm 2 , and more precisely is between 1 and 5 mm 2 .
- mesh size refers to the maximum dimension of the basic pattern forming the mesh (diagonal for a square, a rectangle or a diamond, diameter for a circle, etc.).
- this upper portion 31 is intended to act as a barrier against jellyfish and also against surface pollution.
- the protective net 3 makes it possible to filter jellyfish and also polluting substances of small sizes such as hydrocarbons and dust while allowing the water to pass through.
- the lower portion 31 is intended to be completely immersed and has a second mesh size.
- This second mesh size is between 1 and 2 cm 2 . More particularly, this second mesh size is between 1, 2 and 1, 8 cm 2 . More particularly, this second mesh dimension is equal to 1.5 cm 2 .
- the lower portion 32 effectively filters the jellyfish while allowing the water to pass significantly. This lower portion 32 thus makes it possible to limit the current resistance of the protection system 1.
- this second mesh size makes it possible to prevent the bathers from clinging to the protective net 3 involuntarily. It limits the risk of injury.
- the lower portion 32 and the upper portion 31 may be either formed from the same base piece or from two different base pieces having different mesh sizes and joined during the manufacture of the protection system 1.
- the upper and lower portions are obtained separately and then assembled to form the protective net 3. This assembly is performed by sewing or stitching along a fastening zone 34.
- the protection net 3 is formed of meshes 35 whose general shape at rest remains substantially identical when the system 1 is subjected to significant traction in a transverse direction 300.
- transverse direction 300 is denoted the direction in which the protection system 1 extends and is, in operation, substantially vertical.
- a transverse traction may be applied to the system 1 in particular because of the swell which tends to pull up the floats 2 and the portion of the net 3 disposed near the floats. This traction is all the more important that the lower end of the net 3 is attached to the ground or is weighted.
- FIGS. 4 and 5 illustrate examples of threads 3 whose basic patterns are rectangles and hexagons, respectively.
- the protection system 1 comprises a net 3 having an upper portion 31 and a lower portion 32
- this particular arrangement of the meshes 35 is preferably applied to the lower portion 32 since it generally has a larger area than the upper portion 31 It is also possible to apply this provision to the upper portion 31 only or additionally to the lower portion 32.
- the protection system 1 will absorb only a limited portion of the force generated by the current or the waves which will reduce the stresses to which it is subjected and increase its lifetime.
- the protection system 1 also comprises straps 8 arranged to facilitate the gripping of the system during installation or uninstallation operations and to facilitate docking. These straps 8 can be fixed at the seam of the sleeve 33, as shown in Figure 1 or at the seam binding the upper portion 31 to the lower portion 32 to improve the strength of the fastener. Advantageously, the straps 8 are sewn.
- the protection system 1 also comprises a retaining net 4.
- This holding net 4 has a shape and dimensions adapted to substantially match the shape of the floats 2 so as to wrap these.
- the maintenance net 4 serves to maintain the floats 2 between them so as to form a line of floats 2.
- the assembly consisting of the retaining net 4 and the floats 2 can thus be introduced into the sleeve 33 in a particularly easy manner .
- the support net 4 thus significantly facilitates the assembly and disassembly of the protection system 1. It thus helps to limit the cost of the latter. Moreover, it facilitates the disassembly of the parts of the protection system 1 which is useful especially when certain elements such as floats 2 are damaged.
- the floats 2 and the holding net 4 have a generally cylindrical general shape. This form makes it easier to introduce the floats 2 into the retaining net 4 when it is formed before the insertion of the latter.
- the support net 4 contributes to improving the rigidity of the line of floats 2 which allows to delimit accurately the swimming area protected. In addition, it also improves the strength of the assembly. In particular, if the upper portion 31 is damaged, the support net 4 prevents the floats 2 from escaping.
- the holding net 4 thus housed in the protective net 3 serves neither to form a filter against jellyfish nor against pollution, this function being provided by the upper portion 31 of the protective net 3.
- a mesh dimension substantially greater than the first mesh size will be chosen in order to limit the weight, the cost and the water resistance of the protection system 1.
- the support net 4 comprises stopping points arranged at each interval separating two floats 2. These stopping points can be obtained by tightening the retaining net 4 and are arranged so as to prevent the floats 2 from moving in the retaining net 4 and thereby even in the sleeve 33. This tightening can for example be obtained using a ring, an elastic, a seam, or a knot.
- the protection system 1 comprises a bead passing right through each of the floats 2. The cord thus makes it possible to bind the floats 2 to one another. assembly of the system 1 are therefore facilitated.
- the cord comprises stop means for limiting the movement of the floats along the cord.
- the stopping means comprise at least one stopping point between two consecutive floats. Each stopping point is arranged so as to form a stop to stop the translation along the cord of the floats which are adjacent.
- the floats 2 are held in position even under the effect of strong stresses generated for example by winds or large sea currents.
- the stopping points formed by the holding net 4 make it possible to ensure the regularity of the float line along the system 1 and to improve the rigidity as well as the robustness of the protection system 1.
- the cord and possibly the stopping points can be combined with a retaining net 4 or can equip a protection system 1 without a protective net.
- a stopping point is arranged in the immediate vicinity of the end of each float 2.
- the stopping points arranged on the cord are obtained by a node formed by the cord, or by an element attached to the cord. It is also possible to obtain the breakpoints by thermo welding floats on the cord. For this purpose, it is possible to cover the floats and the cord with a heat-sealable material such as polyurethane.
- the bead has a diameter of 14 mm.
- the protection system 1 also comprises fastening means 7 for securing the protection system 1 with another identical protection system or with an independent element of the protection system 1.
- these means 7 comprise a rope whose first end is connected to both the retaining thread 4 and the protective net 3 and whose other end is connected to an element independent of the protection system 1 or to another protection system 1.
- the attachment means 7 may also comprise laces 9 arranged at regular intervals over the entire length of the protective net 3. For a given protection system 1, each of these laces 9 is arranged to be attached to the protective net. a protection system adjacent to the protection system 1 given. These laces 9 make it possible to maintain the continuity of the protection assembly formed of several protection systems 1. They thus contribute to enhancing the effectiveness of the protection. Preferably one has a lace every fifty centimeters. Thus several protection systems can be put end to end so as to form a floating protection package providing continuous protection over an entire bathing area. A protection package with protection systems of 50 meters in length makes it possible to limit production costs and the difficulties of transport, storage, installation and uninstallation.
- This floating protection assembly also comprises a floating protection system 1, an exemplary embodiment of which has been previously described, as well as a guying system 100.
- This floating protection assembly is shown in FIG. 2.
- the guying system 100 allows to ensure the stabilization of the floating protection system 1 to prevent it from drifting when currents or waves are important. It also makes it possible to maintain the protective net in a substantially vertical position despite the displacement of the floats 2.
- the guying system 100 thus allows the protection system 2 to absorb the movements of the sea without breaking and while maintaining effective protection .
- the guying system 100 comprises a first end 101, one end of which is connected to the protective net 3, and the other end of which is connected to a chain 102.
- the chain 102 is connected to a mass, preferably metal, concrete or stone.
- the guying system 100 is arranged so that the chain 102 rests on the bottom when the sea is not agitated.
- the end 101 is connected to the protective net 3 at the junction between the upper portion 31 and the lower portion 32.
- guying devices 100 may be arranged.
- these various guying devices 100 will be arranged on either side of the protection system 1. than several anchors 103 are preferably fixed on the same chain 102.
- the floating protection assembly also comprises a fish tunnel 200 connected to the lower portion 32 of the protective net 3 and arranged so that the fish can cross the floating assembly only by the tunnel.
- the tunnel 200 comprises a duct 201 inside which are disposed baffles 202.
- the duct 201 has a first opening accessible from the protected area by the protection system 1 and a second opening accessible from the non-protected area by the control system. protection 1.
- the tunnel 200 is intended to be arranged on the bottom.
- the function of the tunnel 200 is to allow fish to pass on either side of the protective net 3, that is to say to pass from the protected swimming area to the unprotected area and vice versa.
- the baffles 202 prevent the jellyfish from crossing the tunnel 200 but allow the fish to do so.
- the dimensions of the tunnel 200 and the baffles 202 will be adapted according to the types of fish that one wishes to cross the entire protection.
- the conduit 201 shown in Figure 3 has a substantially parallelepiped shape.
- the tunnel 200 comprises gripping means 203 which remain accessible when it rests on the bottom. These gripping means 203 make it easy to deposit and remove the tunnel. Moreover, these gripping means 203 make it possible to link the tunnel 200 to the floating protection system 1. These gripping means 203 thus make it possible to ensure a good continuity of the protection, by ensuring that the protection system 1 follows the contour of the tunnel 200 and remains secured thereto by means of the gripping means 203.
- these gripping means 203 comprise two holes formed on a surface of the conduit 201 which remains accessible when the latter rests on the bottom. It can also be provided that these gripping means 203 comprise a rope, an elastic intended to cooperate with these holes. Advantageously, the holes are intended to cooperate with elastics provided with a hook to facilitate the attachment of the protective net 3 on the tunnel.
- the invention also provides effective protection against other species in the water and having dimensions similar to those of jellyfish.
- the protection system 1 is ideal for protecting a swimming area from the intrusion of fish. If the latter do not evolve on the surface, it will of course avoid the use of a tunnel 200 for fish.
- the upper portion 31 of the protective net 3 is made of polyester and has a mesh size of 2 mm 2 .
- the lower portion 32 of the protective net 3 is made of polyamide and has a mesh size of 1.5 cm 2 .
