Description

  The present invention relates to an apparatus for preventing bird nesting.

  Birds such as crows have been nesting on power poles of distribution lines in urban areas and suburbs about 20 years ago. In particular, birds in urban areas often nest using conductive materials such as wire hangers and scraps of electric wires because of easy procurement. However, nesting using a conductive material may cause a power failure or damage to equipment due to a short circuit or a ground fault.

  In addition, when birds nest on a telephone pole, the remainder of the food and scattering of feces occur around the telephone pole, which adversely affects the daily life of the residents from the viewpoint of hygiene. Furthermore, there is a concern that a parent bird may become violent and attack the passing people at the time of the spider web setting.

  Therefore, conventionally, the presence or absence of nesting on a telephone pole is inspected by inspection, and if found, the nest is immediately removed. However, considering the effects of bird flu, etc., workers removing the nest must wear protective clothing, and the removed nest is immediately sealed in a plastic bag or the like to make contact with the outside. There is a problem that the work takes a considerable amount of work because it is necessary to

  In addition, if the utility pole is along a major road, the road administrator must apply in advance for road use for the removal work, which takes administrative time. In addition, depending on the road conditions, the removal work must be performed late at night, which further increases the operation cost.

  On the other hand, Patent Document 1 discloses an apparatus for preventing nesting by stretching a tex in the vicinity of a steel tower. In addition to Patent Document 1, there is an attempt to prevent nesting by arranging a windmill, Kenzan, a light object or the like that birds repel.

Unexamined-Japanese-Patent No. 8-298714

  However, crows, in particular, have the habit of getting used to Tegus, windmills, Kenzan, light objects, etc., and there is a problem that the effect of preventing nesting is weak even if any means is adopted.

  Then, an object of this invention is to provide the orni-nest prevention apparatus which can prevent approach of birds from a viewpoint different from a prior art, and can aim at nest prevention by it.

The nest prevention apparatus according to the present invention includes a phonograph unit that phonographs a cry of a raptor, a sensor that detects the approach of birds, a speaker, a control unit, and a power feeding unit.
The control unit is characterized in that the control unit receives power from the power supply unit and reproduces a cry of the raptor stored in the phonograph unit through the speaker according to a signal from the sensor.

  According to the present invention, it is possible to provide an apparatus for preventing bird nesting which can block the approach of birds and thereby prevent nesting.

Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 1 is a front view of the bird nesting prevention device 1 according to the first embodiment, FIG. 2 is a top view of the bird nesting prevention device 1, and FIG. 3 is a side view of the bird nesting prevention device 1 FIG. 4 is a schematic view showing an internal configuration of the avian nest prevention apparatus 1. Note that for the sake of clarity, the front shield in FIG. 1 and the right shield in FIG. 3 are shown removed.

In the present specification, the term "bird of prey" refers to birds that feed on mammals and other birds such as eagles, eagles, falcons, vultures, condors and owls. Also, "birds" refers to birds that are preyed by birds of prey such as crows, starlings, pigeons, and sparrows. In the following embodiment, a bird of prey is described as an example, and a bird that prevents nesting is described as a crow.
Also, "storing" refers to storing a voice call or the like regardless of whether it is analog or digital.

  In FIG. 4, the bird nest prevention apparatus 1 controls an infrared sensor 2, a power feeding unit, an operation lamp 5, a switch 6, a volume knob 7, an interface unit 8 such as USB, and a speaker 9. And a control unit 10. The power supply unit is configured of the solar panel 3 and the storage battery 4.

  The infrared sensor 2 has a function of detecting the approach of the crows C by detecting infrared rays emitted from the body of the birds crows C. However, a sensor other than the infrared sensor may be used to detect the approach of the crows C.

  The solar panel 3 has a function of receiving the sunlight emitted from the sun S and converting it into electric power. The power from the solar panel 3 is supplied to each part via the control unit 10, and the surplus power is output to the storage battery 4 and charged. At night when the sunlight does not reach, the power of the storage battery 4 can cover the operation of each part. The storage battery 4 is preferably a nickel hydrogen battery.

  The control unit 10 incorporates a storage unit (a phonograph unit) that records raptor, for example, a song of a wolf, and stores it as data. In addition to the roar screams, screams and alert voices may be stored as data in the storage unit.

  In addition, data of a plurality of types of raptors can be stored in the storage unit. For example, when the avian nest prevention device 1 is disposed in proximity, the control unit 10 may select different types of crys between the adjacent avian nest prevention devices 1 and reproduce them from the speaker 9, or random You may select and play a cry. Alternatively, after clocking for a fixed period of time by the clock built in the storage unit 10, the sound to be reproduced may be changed to a different one. By selecting the call of the bird of prey according to such a predetermined rule, it is possible to prevent the crow from getting used to the call and to maintain the anti-nesting effect over a long period of time. Furthermore, the storage unit may be a memory separate from the control unit 10.

  The switch 6 has a function of supplying power to the control unit 10 and each part by the on operation, causing the operation of the avian nest preventing apparatus 1 to be performed, and stopping the operation of the avian nest preventing apparatus 1 by the off operation.

  The operation lamp 5 is turned on in response to the start of the operation of the infrared sensor 2 by the on operation of the switch 6, and is turned off after a predetermined time period Tx after the operation of the infrared sensor 2 is stopped. When the infrared sensor 2 detects the approach of the crows C, this may be notified by blinking.

  The volume knob 7 has a function of adjusting the size of the sound reproduced from the speaker 9. The interface unit 8 is connected to an external PC, and used, for example, for replacing data of a cry of a raptor, rewriting a program of the control unit 10, or reading out a past operation history of the avian nest prevention apparatus 1 it can.

  In the present embodiment, the control unit 10 and the storage battery 4 are accommodated in a sealed case 11. The infrared sensor 2 and the solar panel 3 are installed on the upper shielding plate 12 which covers the upper surface of the housing 11. The upper shielding plate 12 is separated from the upper surface of the housing 11 via the support portion 13 (with a gap), and is attached to the housing 11 by screw fastening. The infrared sensor 2 is covered on the outside by a resin dome 14 capable of transmitting infrared light.

  Further, as shown in FIG. 3, the speaker 9 is an upper surface of the housing 11 below the upper shielding plate 12 so that voices can be well transmitted to the crows C flying above the bird nesting prevention apparatus 1. It is attached facing. However, the entire upper surface of the speaker 9 is doubly covered with a waterproof film 9a and a weather resistant sheet 9b capable of transmitting sound, as measures against rain water. Further, as shown in FIG. 2, a large number of through small holes 12 a are formed in the upper shielding plate 12 at positions facing the speaker 9 so as not to block the sound generated from the speaker 9.

  As shown in FIG. 1, the operation lamp 5, the switch 6, the volume knob 7, and the interface unit 8 are disposed on the front of the housing 11.

  As shown in FIGS. 2 and 3, the front shielding plate 15 is attached to the housing 11 by screw fastening while being separated from the front of the housing 11 (with a clearance) via the support portion 16.

  As shown in FIGS. 1 and 2, the left shielding plate 17 is attached to the housing 11 by screw fastening while being separated from the left side surface of the housing 11 (with a clearance) via the support portion 18.

  Further, the right shielding plate 19 is attached to the housing 11 by screw fastening while being separated from the right side surface of the housing 11 (with a clearance) via the support portion 20.

  A pair of aluminum angle members 21 and 22 are attached to the back of the housing 11. The angle members 21 and 22 having a common shape have a shape in which the bottom plates 21a and 22a are connected at right angles to the vertical plates 21b and 22b.

  In FIGS. 2 and 3, through holes 21c and 22c are formed in the vicinity of the end portions of the bottom plates 21a and 22a. Through holes 21d, 22d are formed at the centers of the vertical plates 21b, 22b, and elongated holes 21e, 22e are formed in the vicinity of the left and right ends.

  In the present embodiment, the long holes 21e and 22e are not used, and the avian nest prevention apparatus 1 is attached to the structure using the through holes 21d and 22d.

  While the vertical plates 21b and 22b are directed horizontally, the angle members 21 and 22 screw the screws 25 inserted through the through holes 21c and 22c into the screw holes of the housing 11, thereby housing the bottom plates 21a and 22a. It can be attached to the back of the body 11.

  The avian nest prevention apparatus 1 can be installed, for example, on a telephone pole or the like for which it is desired to prevent the nesting of crows. When installing the avian nest prevention apparatus 1, as shown in FIG. 3, the vertical plates 21b and 22b of the angle members 21 and 22 are brought into contact with a metal fitting (structure) 26 extending horizontally from a power pole (not shown). . While maintaining this state, the bolt 27 is inserted from the lower side into the through holes 21 d and 22 d from the lower side and is further passed through the hole 26 a of the metal fitting 26, and the nut 28 is screwed to the other end and fastened. The prevention device 1 can be fixed to the fitting 26.

  The upper shielding plate 12, the front shielding plate 15, the left shielding plate 17, and the right shielding plate 19 are formed of an aluminum composite plate in which aluminum and a foamable resin are combined, and shield the housing 11 from sunlight. , It has a heat shielding function to suppress that the inside becomes high temperature. In addition, since there is a gap between the housing 11, the upper shielding plate 12, the front shielding plate 15, the left shielding plate 17 and the right shielding plate 19 and adjacent shielding plates, the case is well ventilated. 11 can be further suppressed.

  Further, the upper shielding plate 12, the front shielding plate 15, the left shielding plate 17, the right shielding plate 19, and the angle members 21 and 22 also have a function of protecting the housing 11 from attacks such as bird's beaks. The reason why the lower surface of the housing 11 is not covered by the shielding plate is because it is difficult for sunlight to reach, and the attack of birds is not performed on the lower surface.

  Although it is preferable to provide a vent with the outside for the purpose of eliminating the pressure change of the housing 11, it is necessary to prevent the entry of rainwater. Therefore, such venting between the vent and the outside can be performed using a screw hole provided in the housing 11. For example, after the casing 11 has a double structure of an outer shell and an inner shell, air permeability can be obtained by separating the screw holes provided in the outer shell and the vents provided in the inner shell by about 45 mm to 70 mm. It is possible to prevent rainwater or the like from invading the housing 11 at the time of a storm, while securing the

  Further, in FIGS. 1 and 3, a cylindrical portion 11 a is formed on the lower surface of the housing 11, and a colored circular fiber sheet 29 is disposed inside the cylindrical portion 11 a, and the lower surface is covered with a waterproof film. A small hole 11 b communicating with the inside of the housing 11 is formed in the bottom wall of the housing 11 above the fiber sheet 29. The small hole 11 b may be used also as the vent of the housing 11.

  If rainwater or the like infiltrates into the case 11, the electronic components in the case 11 may be damaged. In such a case, rainwater or the like that has penetrated into the housing 11 flows downward through the small holes 11 b formed in the bottom wall of the housing 11. When the fiber sheet 29 installed under the small hole 11b gets wet with rain water etc., its color becomes dark, so it can be inferred that rain water etc. has penetrated into the housing 11, so maintenance of the bird nesting prevention device 1 It will be a guide to

  In particular, when the bird nesting prevention apparatus 1 is installed at a high position such as a telephone pole, an inspector who is on the ground whether there is discoloration of the fiber sheet 29 disposed on the lower surface even without approaching the housing 11 It can grasp from visual recognition. The cylindrical portion 11a has a function of enhancing the design of the avian nest prevention apparatus 1 and protecting the fiber sheet 29 from being broken by an external force.

(Operation of the bird nesting prevention device)
Since the avian nest prevention apparatus 1 operates by power supply from the solar panel 3 or the storage battery 4, it can be installed even in a place without a power supply.
When the switch 6 is turned on, the control unit 10 starts control of each part. When the crows C approach the avian nest prevention apparatus 1, the infrared sensor 2 transmits a detection signal to the control unit 10. The control unit 10 having received this reads out the data of the roaring voice from the built-in storage unit, and reproduces the roaring voice through the speaker 9.

  Since the infrared sensor 2 does not transmit a detection signal when the crows C surprised by the roaring cries cries out from the bird nesting prevention apparatus 1, the control unit 10 stops the reproduction of the cries craying from the speaker 9. As a result, since the speaker 9 is made to speak only when necessary, energy saving can be achieved, and even if the bird nest prevention apparatus 1 is installed in a residential area, its quiet environment can be maintained.

  According to the present embodiment, by utilizing the fact that the whale is a natural enemy of crows C, the crows C can be expelled by making the roar of the whales flow from the speaker 9. Since crows C avoid nesting in the vicinity of the avian nest prevention device 1 from instinct, nesting prevention can be realized for a long period of time.

(Modification)
FIG. 5 is a top view similar to FIG. 2 according to a variation of the avian nest prevention apparatus. According to this modification, the casing 11 is formed by the screw 25 in which the angle members 21 and 22 are screwed into the common screw holes of the casing 11 in a state where the vertical plates 21b and 22b are separated and perpendicular to each other. Can be attached to

  The bird nesting prevention apparatus 1 according to the modification can be directly attached to the power pole T which is a structure. Specifically, with the vertical plates 21b and 22b of the angle members 21 and 22 separated, the bottom plates 21a and 22a are attached to each other, and the screws 25 inserted through the through holes 21c and 22c are inserted into the screw holes of the housing 11 The bottom plates 21 a and 22 a are attached to the rear surface of the housing 11 by screwing.

  Further, the stainless steel belt 30 wound around the utility pole T is inserted into the long hole 21 e of the angle member 21 and the long hole 22 e of the angle member 21, and the both ends thereof are connected by the fastening member 31. The clamp 31 has a structure in which the end of the stainless steel belt 30 is gradually wound around the rotation shaft by repeatedly swinging the attached handle, and a predetermined tension can be applied to the stainless steel belt 30. Thereby, the bird nesting prevention apparatus 1 can be attached to the telephone pole T reliably.

  As is apparent from the above, by changing the combination of the common angle members 21 and 22, attachment is possible even when the structure to which the avian nest prevention device 1 is attached changes. In addition, if this modification is used, it can attach directly also to a utility pole etc., without using a metal fitting.

Second Embodiment
FIG. 6 is a front view of the bird nesting prevention apparatus 1 ′ according to the second embodiment. In this embodiment, the support form of an infrared sensor and a solar panel differs with respect to the embodiment mentioned above. The other configuration is the same as that of the above-described embodiment, so the same reference numerals are given and duplicate explanations are omitted.

  In the present embodiment, the infrared sensor 2 is covered by the dome 14 and supported by the cylindrical support 2 a. The support portion 2 a is supported by a tube 2 b penetrating the upper shielding plate 12. The lower end of the tube 2 b is fixed to the upper surface of the housing 11. The wire to which the signal from the infrared sensor 2 is transmitted passes through the inside of the tube 2b.

  The solar panel 3 is tiltably and twistably supported by a flexible support 3 a. Although it is preferable to use what covered the comparatively thick copper wire which transmits the electric power obtained by the electric power generation of the solar panel 3 to the housing | casing 11 with an insulating tube as the supporting material 3a, it is not restricted to it.

  According to the present embodiment, the infrared sensor 2 protrudes upward from the upper shielding plate 12 by the tube 2 b. Therefore, for example, in the installation environment of the bird nesting prevention apparatus 1 ′, the infrared sensor 2 may be disposed so as to protrude above the leaf L even when there is a possibility that the leaf L thickens and covers the infrared sensor 2 This makes it possible to detect crows with high accuracy.

  Further, since the inside of the dome 14 and the inside of the housing 11 communicate with each other through the hollow tube 2b whose inside becomes the air passage, the internal pressure change in the dome 14 can be absorbed, whereby the air pressure in the dome 14 is lowered. Rainwater suction can be avoided. Although the illustration is omitted, the infrared sensor 2 and its support ring, the cavity of the leg of the infrared sensor 2 and the connection portion of the copper wire, the gap of the twisted portion of the copper wire, and the stranded wire continue to the housing 11 , Breathable enough. Similar vents can also be used in the first embodiment.

  Furthermore, according to the present embodiment, since the supporting member 3a is formed of a flexible material, after setting the bird nesting prevention device 1 'at an optimum position, the supporting member is adjusted according to the altitude and azimuth angle of the sun The panel surface of the solar panel 3 can be oriented in an optimal direction by deforming 3a. Thereby, high generated power can be obtained from the solar panel 3.
