Title (EN) WARNING DEVICES FOR BIRDS,AND METHOD OF FITTING
(FR) AVERTISSEURS DE DANGER POUR OISEAUX ET PROCEDE DE MONTAGE
Abstract: front page image
(EN)Warning devices for birds having the specific purpose of attaining a situation conducive to preventing them from flying into a given area. According to the invention, representations (4) - for example in the form of silhouettes - of predatory birds are selected or these warning devices, which silhouettes may be suspended, for example, between successive pylons (10, 11) of overhead high-tension power transmission systems. The invention furthermore relates to a method of fitting representations of predatory birds on or near a group of high-tension wires (12) to which end use is made of a helicopter (100) from which a reel (13) is suspended onto which a bearing cable (1) with the predatory bird silhouettes is wound. The helicopter flies from pylon to pylon while the bearing cable is being unwound from the reel. Cooperation with an operator (14) having taken up his position in the top of each pylon allows a bearing cable to be hung by its ends on two pylons from instance to instance.
(FR)Avertisseurs de danger pour oiseaux dans le but specifique d"atteindre une situation contribuant a les empecher de voler dans une zone donnee. Des representations (4), par exemple ayant la forme de silhouettes d"oiseaux predateurs sont choisies pour ces avertisseurs de danger, lesquelles silhouettes peuvent etre suspendues, par exemple, entre des pylones successifs (10, 11) de systemes de transmission aeriens de courant a haute tension. L"invention concerne en outre un procede de montage de representation d"oiseaux predateurs sur ou a proximite d"un groupe de cables a haute tension (12). A cet effet, on utilise un helicoptere (100) auquel est suspendue une bobine (13) sur laquelle est enroule un cable porteur (1) avec les silhouettes d"oiseaux predateurs. L"helicoptere vole de pylone en pylone pendant que le cable porteur se deroule de la bobine. En cooperant avec un operateur (14) ayant pris position au sommet de chaque pylone, on peut suspendre un cable porteur par ses extremites sur deux pylones de maniere successive.
