Definitions

  • the present invention relates to means for keeping birds away from refuse dumps, water cleaning plants and other large localities. Besides the troubles caused at such places by tight concentrations of seagulls and certain other birds, there are still more serious problems in that the birds, foraging at such places, often give off their waste products at more peaceful places, frequently in nearby lake areas, which may form part of a supply system for drinking water. It is not least for that reason it is desirable to keep the birds away from the discussed places.
  • the building side should be provided with the required access opening or openings for persons or vehicles, but even such openings should be closable by filament material when not in use.
  • Fig. 1 is a perspective view of a system according to the invention, shown under construction
  • Fig 2 is a corresponding, but more detailed view of a part of the system
  • Fig. 3 is a perspective view of the system seen from a corner thereof.
  • Figs. 4 and 5 are perspective view of two different wire clamps.
  • Fig. 1 In Fig. 1 is indicated a refuse dump 2, along the edge of which there is erected a number of masts 4, between which, in the cross direction of the elongate area, there are stretched relatively strong carrier wires 6 in the form of metal cables.
  • the masts There are quite considerable spans between the masts, and since the wires 6 will be subjected to high pulling forces, particularly during the mounting of the system, the masts should be strongly supported by a heavy foundation or with the use of stays 8, optionally by the cables 6 being extended downwardly and outwardly and fastened to a stay anchoring.
  • the cables 6 may be mounted by means of any suitable contractor equipment, though often in quite big heights, e.g. 20 - 30 m.
  • barrage wires 10 should be fastened to the cables, these wires 10 only being indicated in the foremost right hand part of Fig. 1, inasfar as these wires will normally be practically invisible.
  • they can be twisted plastic wires having a diameter of the magnitude 1 mm, and preferably having a dark colour such as fully black, which makes them least visible.
  • These wires should be laid up in parallel with a mutual spacing of e.g. 15 - 30 cm in order to form an effective shelter against intruding birds.
  • the wire 18 is continued or returned in a return wire 20 stretching back to a reversing roller 22 placed at the starting area of the bundle of wires 10 adjacent the carrier cable 16.
  • This roller is mounted on a working basket 24 carried by a crane jig 26, and it will be noted that the rake 12 may be advanced by a pull either directly in the wire 18 or in the return wire 20.
  • an outwardly projecting guiding member 28 for diverting the wires 10 as fed from the reels 14 to the generally or in principle horizontal stretch out over or under the carrier cables 6.
  • each carrier cable 6 By the mounting of the system there is at each carrier cable 6 suspended a working cart 28 accomodating an operator 30.
  • a base plate of this cart is provided with a forwardly projecting carrier beam 32 having upstanding separation fingers 34 for receiving the individual wires 10 between these fingers.
  • the wires may be disposed relatively close to each other, but the operator 30, who can reach the wires from his - working position, will fasten them successively to the carrier cable with the correct, larger spacing. It is imperative that the wires are well controlled for avoiding entangling of the wires.
  • the rake 12 is pulled from the reel end 14 of the system all the way to the opposite end before the operators start fastening the wires.
  • the wires may extend down to lower holding cables 36, to which they are fastened, such that the end walls of the system are also made by the wires.
  • the remaining sides may be made of separate wires 38, Fig. 1.
  • the wall wires should extend outwardly and downwardly sloping, see also fig. 3.
  • triangular openings will be left at the corners, and also these should be covered by wires, 40, as the birds can well find their way through relatively minor openings in the large system.
  • all access openings 42 should be provided with doors or net covers.
  • suspension hooks 44 as shown in Fig. 4 may be used. These may be hooked with clamping action on the cables and be brought to receive the wires by placing the wire in the lower groove and then allow the wire to turn about a vertical axis, whereby, as directly apparent from Fig. 4, the wire will be held by the hook member 44. With this design of the hook members the wires will not be locked against axial displacement relative the hook members, but that can be acceptable in some instances.
  • the lower end of the hook member is provided with a depending flap portion which may be folded up about an integrated hinge and be locked behind a protruding locking nose 46., whereby the wire 10 can be clamped in an effective and simple manner. Generally, such a clamped fastening should be preferred in practice.

Abstract

Divers systèmes basés sur l'effarouchement ont été essayés, avec peu de succès, pour empêcher l'invasion des décharges et autres aires importantes par les oiseaux. La présente invention permet de résoudre le problème de manière radicale en installant un filet ou un treillis supporté par de grands mats (4), complété par des éléments latéraux sur tout le pourtour. L'invention porte sur les méthodes et accessoires rendant particulièrement aisé le montage de cette installation.
