Definitions
- This invention relates to bird scaring apparatus, such as may be employed in an agricultural environment, to discourage birds from eating or otherwise damaging growing produce, fish or the like, or to discourage birds from invading an industrial environment such as an oil rig or an airport.
- the present invention aims at providing a relatively simple form of apparatus which nevertheless is effective at scaring away birds, from a significant area. Accordingly, the present invention provides bird scaring apparatus comprising a plurality of highly reflective surfaces arranged to form a three- dimensional multi-faceted reflecting object, and power drive means arranged to support the object and to effect rotation of the object about a substantially vertical axis.
- the angle between the horizontal and at least some of the reflecting surfaces, externally of the three dimensional object is greater than 90°.
- said at least some of the reflecting surfaces will face upwardly away from the axis of rotation.
- the rotation of the reflecting object catches light as it rotates, sending back into the sky reflected beams of light, especially when the sun shines.
- Trials have shown that these reflected beams are unexpectedly effective at scaring away birds from around the area where the apparatus has been installed.
- the reflecting surfaces are arranged to provide a three-dimensional object in the form of a pyramid with the apex uppermost.
- such a pyramid has three similar reflecting surfaces arranged on a triangular base - that is to say, the reflecting object is in the form of a tetrahedron.
- the apex of the pyramid should lie substantially on the axis of rotation of that object.
- Trials and tests on the apparatus have shown that the angle each reflecting surface of the reflecting object makes to the horizontal is important, having regard to the intended use of the apparatus. I have now found that different birds will be scared by different reflecting angles and the configuration of the reflecting object should be selected having regard to the target to be protected and also the kinds of birds to be scared by the apparatus.
- the internal angle (of the three-dimensional object) each reflecting surface makes with the horizontal may vary from an acute angle through substantially vertical to an obtuse angle to the horizontal.
- the power drive means conveniently includes an electric motor drivingly connected to the multi-faceted reflecting object.
- an electric motor may be of the low-voltage kind so that it may be powered by a battery, such as a lead-acid accumulator of the type employed in motor vehicles. This has the added advantage of being relatively safe, even should the apparatus inadvertently become wet for example during periods of rain.
- the power drive means may be contained in a waterproof housing.
- the apparatus When the apparatus is intended for domestic use, to scare birds from a relatively small vegetable plot in a garden or possibly from a pond, it is convenient to provide an electric motor to effect rotation of the reflecting object which motor is powered by the domestic mains supply.
- the motor in the interests of safety, it is preferred for the motor to require relatively low voltage AC or DC, and for the power for that motor to be transformed from the 240v domestic mains supply down to a safe voltage such as 12v.
- the alternating current supplied from a transformer may be rectified for powering a DC motor.
- the battery should have a suitable capacity to ensure the motor may be driven for extended periods when there may be no sunshine, but as at least some sunshine may be expected most days during the growing season, the capacity of the battery may be significantly smaller than would be required in the event that no solar recharging arrangement were provided.
- wind power could be employed for this purpose , provided the apparatus be installed at a suf f i ci entl y exposed locat ion . Wind power probably would not be suitable for use in a domestic garden, but could be used agriculturally , in a field .
- the reflecting object need not be rotated during the hours of darkness since there are few birds active then, and in any event there is little light to be reflected from the reflecting object. Consequently, it is preferred for the apparatus to include switch means to inhibit rotation of the object other than during the daylight hours.
- switch means could be light-activated or could be in the form of a time switch which may be preset to turn on and off at pre-selected times. If the reflecting object is rotated continuously during daylight hours, birds could become used to the reflections and so ignore it. To prevent this happening, there could be advantages in having the power drive means arranged to operate cyclically, for pre-set on periods alternating with pre-set off periods.
- Figure 1 is a vertical section through a first embodiment of bird scaring apparatus constructed and arranged in accordance with the invention
- Figure 2 is a cross-section through line II-II marked on Figure 1 ;
- Figure 3 is a partial sectional view through a second embodiment of bird scaring apparatus.
- FIGS 4 to 6 show alternative embodiments of bird scaring apparatus of this invention.
- a housing 10 having a removable side wall (not shown) and in which may be located a lead-acid accumulator 11 such as a conventional 12 volt car battery.
- a lead-acid accumulator 11 such as a conventional 12 volt car battery.
- Mounted in the lid 12 of the housing 10 is an electric motor 13, the connecting wires 14 of which are suitably terminated, to permit those two wires to be connected to the two terminals respectively of a battery located in the housing.
- the wires could be provided with screw-eyes, as shown, or for convenience of connecting and disconnecting the battery, the wires could carry bulldog clips.
- the battery could be arranged externally to the housing 10, in a separate enclosure.
- a photocell 15 mounted in the lid 12 of the housing is a photocell 15, connected back to a suitable switching arrangement in the motor casing.
- a solid state switch could be employed, connected to supply power to the motor 13 only when the ambient light exceeds some pre-set value.
- the motor output shaft is coupled to a coaxial gearbox 16 which has a shaft 17 projecting through the lid 12 of the housing.
- a suitable seal (not shown) is provided around that shaft, to prevent the ingress of water, neither to the gearbox nor to the interior of the housing.
- the apparatus further comprises a reflecting three-dimensional object 18, in the form of a tetrahedron made up from three similar planar mirrors 19 (only one of which is visible in the drawing), each of equilateral shape, and a base panel 20 of the same shape and dimensions of the mirrors 19.
- a circular face plate 21 having a boss 22 is attached to the base panel 20 such that the axis of the boss 22 passes through the apex 23 of the reflecting object 18.
- the boss 22 fits on to the output shaft 17 from the gearbox; a pin may pass diametrically through both the boss and the shaft, or the end of the shaft may be D- shaped and the aperture in the boss may be similarly shaped, so that rotation of the shaft is imparted to the reflecting object 18.
- the motor and gearbox are arranged so that in use, the object 18 will rotate at about 30 to 35 rpm.
- the housing should be positioned in an area to be protected so that the reflecting object is above the level of the growing produce. Tests and trials have shown that light reflected from the object serves unexpectedly well at discouraging birds from alighting on the growing produce.
- Figure 3 shows apparatus similar to that of Figure 1 and like parts are given like reference numerals; those parts will not be described again here.
- the apparatus of Figure 3 employs a housing 25 having a lower profile than the housing 10 of Figure 1, and instead of incorporating an accumulator within that housing, power for the motor 13 is obtained from a solar cell panel 26 fitted in the lid 27 of the housing. There is no need for a separate photocell, for the solar cell panel 26 will not generate sufficient power to rotate the object 18 other than when the daylight intensity exceeds some minimum value.
- Figures 4 to 6 show three alternative arrangements from those of Figures 1 and 3. Any of these three further arrangements could use the housing assembly of either of these two Figures, but in Figure 4, the boss 30 is formed as an elongate shaft so that the reflecting object 18 is situated at a relatively great height above the housing 10. Such a configuration may be used with growing crops such as wheat, in which case, the length of the boss 30 might be 500-750mm, or so.
- the embod iment s o f F i gure s 5 and 6 the reflecting object is constructed from triangular panels 31 and 32 respectively , which panels are of isosceles s hape .
- the pane l s 3 1 s hown i n F i gure 5 have a relatively short base and long sides, to give an object with a small included angle at the apex.
- the panels 32 shown in Figure 6 have a relatively long base and short sides, to give an object with a large included angle at the apex.
- the objects described above are all tetra ⁇ hedrons, objects of other shapes could be employed.
- the objects could be pyramidal, and so on a square base.
- more complex three- dimensional objects could be employed, possibly having the reflecting surfaces at various angles to the horizontal.
- the shape and configuration of the three- dimensional object, and also of any tinting applied to the reflective surfaces, may be selected having regard to the birds expected to be in the area where the apparatus is to be positioned.
- the apparatus may thus be "tuned" to the particular birds in order to optimise the scaring effect.
