This invention belongs to the technological field of bird control and refers, more specifically, to a system to inhibit the presence of birds and the respective inhibitor device.
With the advancement of population concentration in large centers, the issue of bird control has been increasingly addressed, not only as a way to contain the inconveniences of a significant increase in the population of these agents, but also as a great ally of public health.
In this scenario, it is important to consider that the unwanted movement of birds, especially in areas of high human concentration, can represent lots of damages ranging from dirt and mechanical damage to air conditioning equipment and gutters, for example, even serious risks to human health.
Thus, it is possible to cite some measures currently used for this purpose, most often in a palliative way, such as the use of viscous gel, to prevent birds from landing in certain locations, spicules equipped with pointed elements, similar to barbed wire fences, with the objective of causing physical damage to the birds and also preventing them from landing in certain areas, protective screens, among other barriers, and, finally, the use of ultrasound emitters.
All the physical barriers mentioned above causes suffering to birds in addition to not being effective, since the birds end up adapting to these barriers and finding other ways to stay in the inappropriate place.
The viscous gel, for example, contrary to what is expected, ends up holding the birds to the place where they should be removed. These birds end up dying and decomposing on the surface, which brings even more risks of contamination. Spicules cause injuries to birds that can also lead to death, also increasing the risk of contamination.
The ultrasound technique, on the other hand, ends up being a solution with temporary effects, since the birds adapt to these waves and over time they start to live with them without major difficulties due to the low impact caused by this type of wave. This solution can even be compared with less efficient solutions such as light reflectors or even the old scarecrows.
Therefore, there are also some alternatives that represent the current state of the art and that are described in patent documents. Some examples can be seen as in the case of U.S. Pat. No. 8,905,459, which discloses a support structure to repel birds comprising a base provided with arms that extend therefrom in different directions and a non-magnetic support rod provided of a magnet, said rod oscillating in response to the wind, in such a way that said magnets generate a variable magnetic field that tends to repel birds.
The Spanish patent no. ES2060998T reveals an electrical system composed of a static pulser that provides one or more connections with high voltage pulses and low electrical power, this voltage being applied to the conductors in order to keep pigeons and other birds, away from the facades of churches, monuments, hospitals and buildings in general.
There is also the German patent document DE10110306 which discloses an electrical measuring and adjustment device, through which the electrical resistance between the conductive wires is periodically measured, in order to deliver the adequate voltage for each type of impedance, aiming at also repel birds.
Finally, it is important to cite the patent document U.S. Pat. No. 2,647,228, which proposes equipment to control the presence of birds in buildings that comprises a wire arranged in the resting places of birds, so that any bird that enters its zone of radiation immediately induces an electrical discharge in your direction.
All these patent solutions presented above cause electric shocks of different intensities to birds, which makes them illegal, as they are contrary to The Animal Welfare Act, so that actions that cause any type of mistreatment to these animals are considered crime, and can be punished with a fine, in addition to imprisonment and other types of legal sanctions provided for.
Finally, from all the inconveniences in the systems and equipment currently used, described above, it is visible the existence of a gap in the creation of a system that inhibits the presence of birds that does not cause any kind of suffering to these animals and that, in an efficient way, prevents its circulation in certain places where it will be installed.
The fact that migratory birds orient themselves with bio-magnetic sensors has been known for decades. It is known that the navigation ability of pigeons and some other birds is based on the ability to detect variations in the Earth's magnetic field.
Baylor College of Medicine researchers, Le-Qing Wu and David Dickman, identified that the responsible for this targeting ability of pigeons is in the cells present in the bird's brain, which record detailed information about the Earth's magnetic field, such as a kind of biological compass.
Therefore, the proposed system and device aims to promote the repulsion of birds from certain locations through an electromagnetic pulse converter in SPIN's, which regulates the alternating current supplied by the grid, reducing its frequency and power to non-ionizing levels. The sinusoidal pattern of the waveform in this circuit favors the generation of the “spin” effect, which increases the amplitude of the electromagnetic waves, allowing the system to be able to drive these birds away without any suffering.
The electrical insulation obtained through the antennas (radiant elements) represents a great technological advance for this field due to the diversity of possible formats and locations to be protected against the presence of birds, since these radiant elements are made of high-quality materials. electrical insulation, in addition to great flexibility and resilience, making it possible to customize the device according to the area to be protected, such as windows or places with easy human access, without the risk of electric shock.
The present device is composed of a converter (1), first capacitor (2), additional capacitors (2n), traction spring (3), magnetic flux carrier cable (5) and connection coil (6), being able to contain, if necessary, one or more radiant sets (4).
The converter, represented in
In an exemplary assembly, as can be seen in
The capacitor (2) (2n), shown in
The capacitors (2) (2n) can be fixed in the structures with the most varied dispositions. Each capacitor (2) (2n) is fixed at the desired perimeters maintaining an average spacing of 2 meters between them. Preferably, in order to guarantee greater stability, the capacitors (2) (2n) can be fixed to the structures by means of fixing pins or screws inserted in the connection hole (2.2) present in the base (2.1), as shown in
For the arrangement of the first capacitor (2) on the surface to be protected, it is recommended that its base (2.1) be arranged opposite to the initial direction of the additional capacitors (2n), ensuring that the pressure exerted by the carrier cable of magnetic flux (5) is contained, keeping the capacitor (2) stabilized, as can be seen in
Similarly to the first capacitor (2), the last capacitor (2n) of the set must also be fixed with the base (2.1) arranged in the opposite direction to the electromagnetic flux carrier cable, also verifiable in
After arranging the web of capacitors (2) (2n) according to the desired design, the coil (6) must be inserted into the initial capacitor (2) and connected to the spring (3) through the connection ends (3.1), establishing the electromagnetic connection between the first capacitor (2) and the last capacitor (2n) and the proper voltage adequacy between the electromagnetic flux carrier cable (5) and the coil (6), as shown in
Next, the electromagnetic flux carrier cable (5) can be arranged over each capacitor (2n) with a single connection turn (5.1) clockwise, until in the last capacitor (2n), the electromagnetic flux carrier cable electromagnetic flux (5) is completely wound without leaving any residue. Both the clockwise arrangement of the connection loop (5.1) and the final winding of the cable (5) serve to ensure the best possible electromagnetic flow, as is well known.
The flow of electrical energy present in the capacitors (2) (2n), being either positive or negative, due to the symmetric rectification caused by the converter (1), generates the “spin” effect, that is, electrical oscillations that provide a rotating electromagnetic field capable of reaching up to 60 centimeters in height, this effect being fundamental to carry out the removal of birds.
The radiant set (4) has the function of directing the electromagnetic pulses to certain places from which the birds are desired, however, access is not possible through the traditional arrangement of the capacitors (2) (2n) or in that the traditional installation can present some risk of electric shock due to the proximity of the movement of people, such as in windows or doors.
For this purpose, the radiant assembly (4) preferably consists of a radiant element (4.5) with high pressure external coating, with a preferential circumference of 1.20 m, connected by means of a retention element (4.4), preferably the PG9 type connector, being fed by a connection cable (4.3) of high isolation connected to the converter (1) through one of the electromagnetic flux carrier cables (5), transporting the electromagnetic flux generated by the converter (1) to the inside the radiating element (4.5).
As seen in
The fixing of the radiant element (4.5) is made through the hole (4.2) in the metallic support (4.1) of the radiant set (4). The fact that the support (4.1) is metallic is fundamental, not only to provide support, but also to enable an adequate grounding of the set.
The radiant element (4.5) is made of flexible material, and can freely assume different formats, according to the area to be protected against the presence of birds, as can be seen in
After fully assembled, the proposed device provides a pulsating symmetrical direct current through the converter (1) fed with a preferred nominal voltage that can vary from 90 to 235 volts, consuming an average power at full load of approximately 14 watts.
The converter (1) operates with a primary frequency of 120 hertz, and in the feedback process, this frequency can reach 30 mega Hertz, limited to the current applied in the electronic circuit, due to the arrangement of the capacitors (2) (2n), and the frequency control occurs automatically.
However, the operating power of the converter (1) must be manually regulated, via a potentiometer (1.1), according to the total desired area of protection for each type of installation, considering an output current of the electrical pulses of approximately 5 m A/h as a pulse output voltage of approximately 1.5 kV.
Because of the way this system operates, there is a process of emission of free electrons by the capacitors (2) (2n) and radiant sets (4) or metallic cables of any kind, through high-insulation cabling. These free electrons are launched omnidirectionally, reaching average heights of up to 60 centimeters.
The aforementioned flow of free electrons is responsible for keeping the birds away from the desired perimeter, as it causes a momentary discomfort that leads to flight disorientation. This is the reason why birds do not approach locations with this kind of energy.
The system that operates the device comprises the six steps below:
The SPIN's generation effect is achieved due to an LRC set, that is, inductance, through a coil (6) consisting of only one turn; resistance, through the characteristic resistance of the transport cables themselves (5); and capacitance, caused by the application of capacitors (2) (2n) in the set. This whole set is necessary to obtain the desired energy field, that is, capable of keeping the birds away.
The figures presented as well as the description provided herein do not have the power to limit the ways of implementing the system and device proposed herein, serving only as an illustrative and preferential basis for this solution. Therefore, it is possible that there are other equivalent forms that do not escape the revealed scope of protection.
This descriptive report presented a system and device that inhibits the presence of birds composed of a device that generates a directional and rotating electromagnetic flow capable of inhibiting the presence of birds due to the emission of an electromagnetic frequency that affects the orientation of the flight, forcing it to those to change route, without the emission of noise or any risk of suffering and physical damage to these birds, endowed with novelty, inventive step, descriptive sufficiency, industrial application and, consequently, covered with all the essential requirements for granting the privilege claimed.
