Definitions
- the invention relates to the field of protective shells intended to cover longitudinal elements, in particular cables or pipes in an environment subject to the presence of rodents, mammals, or other animal categories, which may corrode or damage the elements.
- longitudinal components and their components are intended to cover longitudinal elements, in particular cables or pipes in an environment subject to the presence of rodents, mammals, or other animal categories, which may corrode or damage the elements.
- optical fiber cables described in patent WO99 / 59166 have been developed for the purpose of removing rodents by adding insulating mass and repellent fibers: these products do not represent the entire market and imply, subject to their effectiveness. , disconnect the electrical systems to dismantle the entire network and change the cables.
- the attack is less often on the cable than on the end thereof where a bunch of cables of smaller sections is connected to the connectors. Small sections have less insulation in volume and are therefore particularly fragile in the face of rodent attack.
- ultrasonic boxes sold for vehicles have a high price, an additional purchase constraint for the user, installation costs and additional energy consumption for powering the device.
- the present invention proposes a protective envelope intended for overlaps of longitudinal elements such as cables or pipes, the protective envelope comprising a textile comprising at least one irritating material, and at least one thermoplastic material, the irritating material having an elongation at break of less than 10% and preferably less than 6%.
- a protective envelope intended for overlaps of longitudinal elements such as cables or pipes, the protective envelope comprising a textile comprising at least one irritating material, and at least one thermoplastic material, the irritating material having an elongation at break of less than 10% and preferably less than 6%.
- 'irritant material' is meant in this document a fragile and easily broken material whose fragments are likely to irritate a certain category of animals, such as rodents capable of biting the envelope. , especially in the mouth and respiratory tracts. This irritating effect is achieved by the bite of any type of animal, from rodents, mustelids to the aquatic animal, or other mammals, who would take the protective envelope in the mouth.
- the present invention makes it possible to dissuade rodents or other animal species from attacking the protective envelope and thus from protecting electrical and communication cables or any other longitudinal object. Indeed, many behavioral studies show that an undesirable effect occurring just after a specific act causes the animal to adapt its behavior to avoid the undesirable effect. When the rodent is gnawed the envelope once, its irritating character stops him and discourages him to start again.
- the protective envelope is configured to be attached to longitudinal elements, such as cables or pipes, the protective envelope comprising a woven, non-woven, knitted, or braided textile, comprising at least one irritant material, and at least one thermoplastic material, the irritating material having an elongation at break of less than 10% and preferably less than 6% so as to break into irritating fragments under the effect of the bite of an animal. After bite, the mouth of the animal is filled with irritating fibers and it does not repeat his gesture.
- the product does not break in the hands of the installer.
- the textile form has a flexibility that allows to fix in a desired shape the protective envelope, which can thus be adapted to the shapes of the longitudinal elements to be protected.
- textile is meant herein any arrangement of yarns, such as woven, nonwoven, knitted, braided yarns, etc.
- the textile is an arrangement of woven, non-woven, knitted, or braided yarns.
- yarn is understood herein to mean an assembly of fibers that may especially have been pretreated prior to being used to form filaments.
- the yarns may consist of monofilaments or multifilaments and then are arranged to form said textile.
- the yarns are pre-milled, that is to say that the yarn is turned on itself a given number of turns per meter, or gimped, that is, that is, the gimped yarns are treated to comprise a core yarn and a yarn wound around the core yarn so as to form a coating agent before forming the fabric.
- the textile used to form the protective envelope according to the present invention is flexible, unlike known materials comprising glass fibers or other irritant material cast in a thermoplastic matrix, coated or coated with a thermoplastic resin which form composite solid materials.
- This makes it possible to position the envelope easily around the functional longitudinal element but which, according to the site where it is positioned, needs to be protected.
- the protective envelope may also be reported on a local portion only of this longitudinal element which is known to be susceptible to degradation by the bite. It may even be envisaged to use the protective envelope to cover all or part of a longitudinal element already placed on a site of use in which it is subjected to the attack of animals.
- This configuration confers undeniable advantages to the present invention, especially in terms of cost compared to techniques which provide protection by the introduction of irritating fibers at the very core of the layers forming the cable, even before it is functional ( or any other longitudinal element) and which require dedicated manufacturing steps.
- This is also verified with respect to other known methods which provide for forming one or more layers by multi-filament winding of glass or winding of woven fiberglass strips around an already manufactured and functional cable.
- this known technique it is indeed necessary to protect the entire length of the cable (or the longitudinal element) before positioning on the site and not to limit the protection risk portions only.
- this protection provided on the entire longitudinal element considerably increases the weight of the latter which is then more difficult to handle.
- the protective envelope forms an outer protective sheath, configured to be attached to a longitudinal member so as to protect it.
- the longitudinal element is already manufactured before being covered by the protective envelope, in the sense that the longitudinal element as such can fulfill its final function even before being covered and protected by the protective envelope , forming an outer protective sheath.
- the envelope is already manufactured separately from the longitudinal element to which it must be reported to form external protective sheath. According to one possibility, the protective envelope is only formed by this textile.
- the textile comprises at least one irritating material in a proportion of between approximately 50 and 85% by weight. This value range makes it possible to optimize the irritating properties while maintaining the mechanical strength of the envelope.
- At least one irritating material has a Young's modulus of between approximately 40 and 900 GPa. This ensures that the irritant material breaks under the bite of an animal becoming irritating, as well as for a material whose elongation at break is less than 10% or even less than 6%.
- the textile of the protective envelope further comprises at least one metallic material.
- the metallic material may be present in the textile in the form of metal wires used as a bite dam and in addition to the other materials of the protective envelope. Indeed, a textile consisting solely of metal threads encourages the contrary harmful animals to gnaw to limit the growth of their teeth.
- At least one thermoplastic material of the protective envelope is a polymer chosen from PET (polyethylene terephthalate), PET-FR (acronym for polyethylene terephthalate Flame Retardant), PP (polypropylene), LDPE (low density polyethylene ), PEhd (high density polyethylene), PBT (polybutylene terephthalate), PA4.6 (polyamide 4.6), PAU (polyamide 11), PA6.6 (polyamide 6.6), PA12 (polyamide 12), PPS (phenylene polysulfide) , PTFE
- thermoform the protective envelope in particular in a cylindrical shape to receive cables.
- ECTFE ethylene chlorotrifluoroethylene
- PVDF polyvinylidene fluoride
- ETFE ethylene tetrafluoroethylene
- PFA perfluoroalkoxy
- PEEK polyetheretherketone
- PMMA polymethylmethacrylate
- these materials are used in the form of resin and are less hard and less resistant to rodent bite than are the prior art totally made of metal. Rodents are therefore not encouraged to file their teeth by regular and repeated contact.
- At least one irritating material of the protective envelope is selected from inorganic materials, such as glass, carbon, basalt, boron, silica carbide, silica, and ceramic son son. .
- inorganic materials such as glass, carbon, basalt, boron, silica carbide, silica, and ceramic son son. .
- These materials are chosen for their fragile and brittle nature so as to irritate the mouth of the animal that gnawed the envelope.
- the son of glass for example break under the load of a bite and the mouth of the animal is filled with fine and irritating fibers and the animal stops its attack.
- several studies show that when a harmful event occurs, the animal memorizes the place and the action and does not reiterate its action in the same place. This material then also has a deterrent effect for the animal that has been a first time in contact.
- the textile also comprises at least one repellent material, such as denatonium benzoate, ricinius speciis seed oil and palmitamidopropyl dimethylamine.
- at least one repellent material such as denatonium benzoate, ricinius speciis seed oil and palmitamidopropyl dimethylamine.
- repellent material in this document a material configured to repel a certain category of animals such as rodents, it may especially be an olfactory repellent and / or taste.
- the repellent material provides a deterrent component to the attack of the envelope by the animals considered.
- the repellent material is included in the composition of the thermoplastic material and / or the composition of the irritant material.
- thermoplastic material is incorporated in the composition for example by an intimate mixture of masterbatch type or adding additive at the time of extrusion of the thermoplastic material.
- said repellent material is coated on the textile forming the envelope or on the son constituting the textile.
- the textile of the protective envelope is woven and comprises weft threads and warp threads, preferably each of the weft threads consists of the at least one thermoplastic material and each of the warp threads consists of of the at least one irritating material.
- the fabric can be thermoformed in a determined configuration.
- the application of a stress in a direction perpendicular to the direction of the warp of the woven fabric results in the weft yarns curving around this same direction.
