Definitions

  • the present invention relates to bird deterrent means.
  • the invention is directed to a device for deterring birds from perching or roosting on moored boats, the coping and cornices of buildings, railings and the like.
  • a device for deterring birds from perching, or roosting, on a moored boat, a building or other structure having a broad surface attracting birds for perching said device comprising electrical circuit means for generating a pulsed electrical voltage at an output, and electrical conduction means supported upon said surface and connected to said output to form electrically charged regions, said regions being arranged in lines in a spread-out pattern with said lines so widely spaced and located to permit movement of a bird between said lines but requiring to be crossed by the bird in its passage to an edge of the surface.
  • the conduction means are flat metal ribbons which are laid in parallel pairs closely-spaced along the surface of the boat, or structure, so that when a bird's foot bridges the conductors, it will receive an electric shock from the voltage pulses.
  • the conduction means are flat metal ribbons which are laid in parallel pairs closely-spaced along the surface of the boat, or structure, so that when a bird's foot bridges the conductors, it will receive an electric shock from the voltage pulses.
  • the craft is composed of timber, or fibre glass.
  • a single conductor in the case of a metal hull, can be laid over the boat insulated therefrom by a thin ribbon insulator, the other terminal of the output of the electrical circuit means being connected to the boat body.
  • the electrical circuit means provides a high voltage/low current pulse output which shocks the bird, but does not harm it.
  • the shock is a sufficient deterrent to frighten the bird from th boat and, unlike other known deterrents, birds do not become accustomed to such electrical shocks.
  • a conductor insulated from the rail need only be arranged on the upper portion of the rail and the other terminal of the output of the electrical circuit means connected directly to the rail.
  • the present invention utilizes the principle of electric fences which are used to restrict cattle within a certain area.
  • such known electric fences cannot be applied directly to boats, or the other structures referred to above since the voltages used are not suitable and the arrangement of the conductors and their insulation from fence posts are inapplicable to boats.
  • the earth is one terminal of the applied power.
  • the pattern of the electrical charged regions is broad, i.e.
  • Narrow spacing might at first be considered necessary to ensure that an alighting bird does not avoid contact with the regions.
  • Such close spacing of the electrical conductors would detract from the appearance of a boat as well as add considerably to the cost.
  • the perching habit of many of the troublesome birds which entail early movement of the bird towards the gunwale enables the pattern of the ines of conductors to be widely spread and therefore intercept the movement of the bird shortly after alighting.
  • the conduction means is preferably constructed as flat ribbon which can be adhered to the horizontal surfaces of the hull and cabin of the boat but is insulated from the surface by a thin insulating layer provided with a pressure-sensitive adhesive. Electrical conductor strips are exposed on the topside of the ribbon for contact with the bird. In this manner, the conductors need only be laid on those portions from which the birds are to be deterred, and the high voltage pulses do not interfere with other electronic equipment on board the boat.
  • the same ribbon may be used on the topside of rigging.
  • the ribbon applied on the topside of the metal rail requires only a single electrical conductor with the opposite terminal of the electrical circuit means connected directly to the metal rail.
  • Fig. 1 is a partial diagrammatic representation of a marine launch to which the bird deterrent device according to the invention has been applied;
  • Fig. 2 is a perspective of an electrical control for said device.
  • Fig. 3 is a circuit diagram of the electrical voltage pulser. BEST MODE OF CARRYING OUT THE INVENTION
  • the control 10 for the bird deterrent device includes an electrical circuit (Fig. 3) in a housing 11 which can be affixed in the cockpit 12 of the boat 13 (Fig. 1).
  • the input of the control 10 is connected to a D.C. voltage supply, typically a 12 volt battery, by leads 14.
  • a pulsed output voltage is provided at the output terminals 15 of the control 10.
  • the amplitude of the voltage pulses can be controlled by switch 16 and the frequency of the pulses can be varied by a control 17.
  • a light emitting diode 18 can also be provided to indicate the impulse timing.
  • a pair of conductors 19 and 20 are connected to respective output terminals 15 of the control 10.
  • the conductors 19 and 20 are flat metal ribbon conductors with an adhesive coating on their underside so that they can be affixed to a broad surface of the boat such as the deck 21 from which the birds are to be deterred from perching.
  • the conductors 19 and 20 are spaced about 15 ram apart and also include a thin underside electrically insulating layer which insulates the live conductor from the boat deck 21.
  • the pair of conductors 19,20 are laid parallel and closely spaced so that a bird's foot can span both conductors 19,20. A bird thereby provides a conductive path between the conductors 19,20 and will receive an electric shock from the next voltage pulse produced by the control 10.
  • Both conductors 19 and 20 may be carried upon a common insulating layer.
  • the ribbon may carry a single electrical conductor, say conductor 19, upon the insula ing layer with the output terminals 15 connected respectively to the conductor 19 and the metal railing 22 of the boat, or to the deck 21 if composed of metal.
  • the ribbon of conductors 19 and 20, or conductor 19 alone will be permanently attached to the deck 21, it may be instead affixed upon a plastics sheeting which can be laid out and recovered as desired.
  • conductors 19 and 20 are supported directly upon the deck 21 or the plastics sheeting, at least one of the conductors 19, 20 may be supported in a raised (or shielded) position to minimise any shorting effect which might be created by the presence of dew or rain.
  • each conductor 19 and 20 may be a flexible metal braid, of the type known as "Monel" mesh sewn to the insulating layer, or may be a metallised plastics tape.
  • the electrical circuit for the control 10 is shown in Fig. 3.
  • the circuit is powered from a voltage supply which may be from 9V to 28V DC.
  • a voltage regulator LM 317T is connected to the voltage supply so as to provide a steady voltage power supply to the circuit.
  • Diode D1 is used as a protection diode and capacitor C1 as a filter capacitor.
  • Resistors R5 and R6 adjust the output voltage of the regulator to approximately 8V.
  • a 2N 6027 programable unijunction transistor (PUT) Q1 initiates a discharge cycle by supplying a brief pulse to the gate G of the SCR. This causes the SCR to turn on, discharging the capacitor C5 through the coil W1. The SCR will remain on until the discharge current falls below its "hold on” current.
  • the rate at which the PUT transistor supplies trigger pulses to the SCR depends on two factors, viz. a reference voltage set on its own gate by the ratio of resistors R2 and R3, and the time constant of resistor R4 and capacitor C3. When capacitor C3, and hence the anode A of transistor Q1, reach a voltage of 0.6V higher than the reference voltage, the device switches on.
  • the capacitor 3C This allows the capacitor 3C to discharge into the gate G of the SCR thereby supplying a trigger pulse.
  • the neon fires at approximately 90V through resistor R10 and is used as an indicator.
  • the pulse produced with a 50 ohm load, approximately once every second, will have a voltage of 2KV at 250mA.
  • the circuit imposes only a small drain on the voltage supply, typically 25mA into a 500 ohm load at 2KV. Accordingly, battery life will not be a problem. Furthermore, when a high voltage shock is imparted to a bird, only a negligible amount of current, and hence power is used.
  • the device can be activated merely by a flick of a switch and will not interfere with normal sailing or motoring activities.

Abstract

Dispositif pour dissuader des oiseaux de se percher sur une structure à surface large, par exemple un bateau ou un bâtiment, où des conducteurs à impulsion électrique sont appliqués à la surface selon un réseau de lignes largement espacées permettant à un oiseau de marcher entre des lignes voisines mais qui sont traversées lors du passage de l'oiseau à un bord de la surface. L'impulsion électrique est inoffensive pour l'oiseau mais suffisante pour lui faire peur.
