Description

  The present invention relates to a nesting prevention apparatus for preventing birds from building a nest on a utility pole or the like.

  Birds such as crows, for example, make a nest on the pole of a utility pole in early spring, for example, and there is no end to the case where a distribution line accident occurs. For this reason, when a nest is found during a patrol inspection, the nest is removed, and a windmill or a needle-type bird damage prevention device is attached to the armor to prevent the birds from forming the nest. However, even if such preventive measures are taken, it is difficult to effectively prevent nesting because the nesting place can be changed and the birds become accustomed.

  On the other hand, there is known a technique for preventing a nesting of an arm by attaching a cover over which a thread is stretched to the arm of a utility pole (see, for example, Patent Document 1).

Special Table 2002-524671

  However, in the technique of the above-mentioned Patent Document 1, even if a cover over which a thread is stretched is attached to the arm itself, a crow or the like may be caught by an electric wire near the arm and make a nest on the cover. In other words, nesting cannot be effectively prevented.

  Then, this invention aims at providing the nesting prevention apparatus which can prevent nesting more effectively.

  In order to solve the above-mentioned problems, the invention of claim 1 is a nesting prevention apparatus for preventing birds from forming a nest, comprising a dummy nest imitating the bird's nest, and a dummy nest arranged in the dummy nest. A dummy egg imitating the bird's egg, an egg holding means for detecting the egg holding of the dummy egg by the birds, and when the egg holding is detected by the egg holding detection means, the birds And a threatening means for threatening and driving away.

  According to the present invention, when a bird such as a crow approaches a dummy nest and holds a dummy egg, the egg holding means is detected, and the bird is driven away by the threat of the threat means.

  According to a second aspect of the present invention, in the nesting prevention apparatus according to the first aspect, the egg-holding detecting means is constituted by an activation switch that activates the threatening means, and the threatening means is turned on by the egg-holding and the threatening The means is adapted to be activated.

  The invention according to claim 3 is the nesting prevention apparatus according to claim 1 or 2, wherein the threatening means vibrates the dummy egg.

  The invention of claim 4 is the nesting prevention apparatus according to claim 1 or 2, wherein the threatening means inflates the dummy egg.

  According to the first aspect of the present invention, when a bird holds a dummy egg, the bird is threatened and driven away by a threatening means, so that nesting can be more effectively prevented. In other words, in accordance with habits and instinct, the birds threaten the birds while holding the dummy eggs, so that it is possible to more effectively drive away the birds and prevent nesting more effectively.

  According to the invention of claim 2, when the bird holds the dummy egg, the start switch of the egg detection means is turned on and the threatening means is started. In other words, in a state where the birds do not hold the dummy eggs (normal time), it is possible to reduce the power required for starting and operating the threatening means, and it is possible to reduce the power consumption of the entire apparatus.

  According to the invention of claim 3, when the birds hold the dummy eggs, the dummy eggs vibrate, so that the birds are surprised and separated from the dummy nest. In this way, it is possible to more effectively drive away birds and prevent nesting more effectively.

  According to the invention of claim 4, when the birds hold the dummy eggs, the dummy eggs expand, so that the birds are surprised and separated from the dummy nest. In this way, it is possible to more effectively drive away birds and prevent nesting more effectively.

This nesting prevention device 1 is a device for preventing birds from building a nest, and mainly includes a dummy nest 2, a dummy egg 3, and a device body 4. Here, in this embodiment, the case where the birds are crows K and the nest is prevented from nesting in power facilities such as utility poles and power transmission towers will be mainly described.

  The dummy nest 2 is an artificial nest that imitates and imitates an actual nest of a crow K, and is made of an electrically insulating material (for example, plastic). Specifically, it has a substantially cage shape, and a plurality of drain holes 2a are formed in the bottom and the wall, and although not shown, a large number of artificial branches are arranged to form a bed. Here, it may be made of a deformable material so that the dummy nest 2 can be deformed according to the arrangement position or the like, or the size and shape can be changed like a universal steamer.

  The dummy egg 3 is an artificial egg that is arranged in the dummy nest 2 and imitates and imitates an actual egg of crow K, and is made of an electrically insulating material (for example, plastic). Specifically, it is arranged at the bottom (bed) of the dummy nest 2, and the number of arrangement is the same as the normal number (for example, 2, 3) that the crow K actually lays eggs in the nest and warms. Is set. Each dummy egg 3 is connected to the apparatus body 4 (movable switch 42 and the like) as will be described later.

  The device body 4 is a device in which devices for preventing nesting by the crow K are accommodated, and as shown in FIG. 2, a warming switch (egg detection means) 41 and , A movable switch (egg detection means) 42, a power source 43, a vibrator (intimidation means) 44, a buzzer (intimidation means) 45, and a central processing unit 46 for controlling these.

  The sensation switch 41 and the movable switch 42 are sensors that detect the incubation of the dummy egg 3 by the crow K, and are configured by a startup switch that activates the vibrator 44 and the buzzer 45. 44 and the buzzer 45 are activated.

  Specifically, the temperature sensation switch 41 is turned on when a temperature rise is detected. For example, the temperature sensation switch 41 is made of bimetal and is disposed on the upper surface side of the casing of the apparatus main body 4. Then, when the crow K holds the dummy egg 3 and the abdomen of the crow K comes into contact with the upper surface of the housing, the temperature around the upper surface of the housing rises, and when the temperature reaches a predetermined temperature, the warm feeling switch 41 is turned on. It has become. In this way, when the warm feeling switch 41 is turned on, the incubation of the dummy egg 3 by the crow K is detected.

  The movable switch 42 is turned on when pressed, and is connected to each dummy egg 3 via a connecting rod 31, as shown in FIG. When the dummy egg 3 is pressed by the crow K holding the dummy egg 3 (when the dummy egg 3 moves), the movable switch 42 is pressed and the movable switch 42 is turned on. Yes. In this way, when the movable switch 42 is turned on, the incubation of the dummy egg 3 by the crow K is detected.

  Such a warm feeling switch 41 and the movable switch 42 operate | move without requiring electric power.

  The power supply 43 is a power supply for starting and operating the vibrator 44 and the buzzer 45, and in this embodiment, is constituted by a battery.

  The vibrator 44 and the buzzer 45 intimidate and drive away the crow K when the incubation of the dummy egg 3 by the crow K is detected by the warm feeling switch 41 and the movable switch 42.

  Specifically, the vibrator 44 vibrates the dummy eggs 3 and is connected to each dummy egg 3 via the connecting rod 31. When the warm switch 41 and the movable switch 42 are turned on as described above, the power source 43 is turned on, the vibrator 44 is activated, and vibration is started. Along with this, each dummy egg 3 vibrates via the connecting rod 31. This vibration time is set to a time sufficient to threaten and drive away the crow K.

  The buzzer 45 emits a sound that the crow K dislikes, and includes a sound source and a speaker. When the temperature switch 41 and the movable switch 42 are turned on as described above, the power source 43 is turned on, the buzzer 45 is activated, and a sound is emitted. The sound output time is set to a time sufficient to threaten and drive away the crow K.

  Here, in this embodiment, when the egg hold of the dummy egg 3 by the crow K is detected by at least one of the thermal switch 41 and the movable switch 42, both the vibrator 44 and the buzzer 45 are activated and actuated. It is like that. On the other hand, when the incubation of the dummy egg 3 by the crow K is detected by both the warm feeling switch 41 and the movable switch 42, both or one of the vibrator 44 and the buzzer 45 is activated and operated. Also good. Alternatively, when the egg-holding is detected by the warm feeling switch 41, one of the vibrator 44 or the buzzer 45 is activated, and when the egg-holding is detected by the movable switch 42, the other of the vibrator 44 or the buzzer 45 is turned on. You may make it start.

  Furthermore, the activation of the vibrator 44 and the buzzer 45 may be switched every time an egg is detected (degree of egg holding). For example, the threatening method may be changed alternately such that the vibrator 44 is activated in the first detection, the buzzer 45 is activated in the next detection, and the vibrator 44 is activated in the subsequent detection. As a result, it is possible to prevent the crow K from being intimidated (learned), and to appropriately and surely remove the crow K.

  As shown in FIGS. 1 and 3, a flat plate-like magnet body 5 is disposed on the lower surface of the casing of the apparatus main body 4. The nesting prevention device 1 can be attached to and detached from the attachment target by attaching the magnet body 5 to the attachment target such as a metal arm of a power pole.

  Next, the operation of the nesting prevention apparatus 1 having such a configuration will be described. Here, it is assumed that the nesting prevention device 1 is attached to a power facility such as a utility pole as described above.

  First, when the crow K approaches the dummy nest 2 and holds the dummy egg 3 based on the habit or instinct of holding an egg, the egg holding is performed by the warm switch 41 and the movable switch 42 as described above. Detected. Subsequently, the power supply 43 is turned on to activate the vibrator 44, the dummy egg 3 vibrates, and the buzzer 45 is activated to generate a sound. As a result, the crow K is surprised and escapes from the dummy nest 2.

  As described above, according to the nesting prevention apparatus 1, when the crow K holds the dummy egg 3, the crow K is intimidated and driven away by the vibration and sound of the dummy egg 3, thereby preventing the nesting more effectively. Is possible. That is, in order to intimidate crow K in the state where crow K is holding and holding dummy egg 3 according to habits and instinct etc., crow K is more effectively surprised and driven away, and nesting is more effectively prevented It becomes possible.

  Moreover, when the crow K holds the dummy egg 3, the dummy egg 3 vibrates, so that the crow K is more surprised and moves away from the dummy nest 2. That is, since the egg does not vibrate in nature, the crow K is surprised and leaves the dummy nest 2. In this way, it is possible to more effectively drive away the crow K and prevent nesting more effectively.

  The temperature switch 41 and the movable switch 42 operate without requiring electric power. When the crow K holds the dummy egg 3, the temperature switch 41 and the movable switch 42 are turned on and the vibrator 44 and the buzzer 45 are activated. To do. In other words, in the state where the crow K does not hold the dummy egg 3 (normal time), power to the sensation switch 41, the movable switch 42, the vibrator 44, and the buzzer 45 is unnecessary, so that the power consumption of the entire apparatus is reduced. Is possible.

(Embodiment 2)
FIG. 4 is a schematic block diagram showing the apparatus main body 4 of the nesting prevention apparatus 1 according to this embodiment, and the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted. .

  This embodiment is different from the first embodiment in that an expander (intimidating means) 47 that expands the dummy egg 3 is provided in place of the vibrator 44.

  That is, in the first embodiment, the dummy egg 3 can freely expand and contract like a balloon, and is connected to the expander 47 via the hollow connecting rod 31, and the expander 47 is an air tank that stores compressed air. It has. When the egg hold of the dummy egg 3 by the crow K is detected by the warm feeling switch 41 and the movable switch 42, the power source 43 is turned on to activate the inflator 47, and the dummy egg 3 is removed from the air tank via the connecting rod 31. Compressed air flows through the dummy egg 3 so as to expand. Further, the expander 47 is provided with a release valve. When the release valve is opened, the compressed air in the dummy egg 3 flows to the outside, and the dummy egg 3 contracts again.

  Thus, according to this embodiment, when the crow K holds the dummy egg 3, the dummy egg 3 expands, so that the crow K is more surprised and moves away from the dummy nest 2. That is, the egg does not swell in nature, so the crow K is surprised and leaves the dummy nest 2. In this way, it is possible to more effectively drive away the crow K and prevent nesting more effectively.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, the egg-holding detection means is composed of a thermal switch 41 and a movable switch 42 that do not require electric power, and is an activation switch that activates the vibrator 44 and the buzzer 45, but the egg-holding detection means requires electric power. It may be a simple sensor. For example, the egg-holding detection means is constituted by a temperature sensor or a pressure sensor, and the detected ambient temperature and pressure to the dummy egg 3 are sequentially transmitted to the central processing unit 46. Then, the central processing unit 46 may determine and detect the incubation of the dummy egg 3 by the crow K based on the ambient temperature and pressure, and activate the vibrator 44 and the buzzer 45.

  Further, threatening may be started by activating the vibrator 44, the buzzer 45, and the inflator 47 after a predetermined time from detecting the egg hug. This makes it possible to intimidate the crow K in a state where the crow K is holding the dummy egg 3 in a calm state or in a state of being relieved, and can be more effectively surprised and driven away. .
