Description

The present invention relates to a wild animal repelling device for intimidating and repelling wild animals, typified by mammals and birds, that appear in agricultural lands, ranches, especially rice paddies, vegetable fields, marine farms, and the like.

In recent years, areas infested with wild animals (deer, wild boars, bears, etc.) have expanded due to factors such as wildlife protection, expansion of human living environments, depopulation of rural areas, abandoned cultivation, and a decrease in the number of hunters. The damage to these areas has become serious.

Until now, in order to protect crops from wild birds and animals, the installation of electric fences (for example, Patent Document 1), the evacuation of wild animals by using acoustics such as ultrasonic waves and explosive sounds (for example, Patent Document 2), and the prevention of natural enemies such as lions and wolves. A variety of measures are being taken, including the spraying of repellents that smell like excreta, and hunting and trapping to secure and exterminate pests.

In addition, a wild animal repelling device that uses a shape similar to a wolf, a threatening sound, and a light to intimidate wild animals has been reported (for example, Non-Patent Document 1).

Is "Monster Wolf" effective? Video of repelling bears, deer, and monkeys - Read and see photos - Sankei Photo, [online], November 27, 2017, [searched March 29, 2022], Internet <URL: https://www.sankei .com/photo/story/news/171127/sty1711270007-n1.html＞

However, in the case of the electric fence described in Patent Document 1, installation and maintenance are cumbersome, the undergrowth must be kept short to prevent electricity short-circuiting, installation and removal work is labor-intensive, and accurate Coupled with the aging of farmers, it is becoming increasingly difficult to ensure proper methods of pinning. There was also the problem of safety risks such as electric shock accidents. Furthermore, animals that break through the electric fence and enter the fields cannot easily get out of the electric fence, causing further damage to the fields.

Furthermore, although the method of evacuating wild animals using sounds such as explosive sounds described in Patent Document 2 has a temporary repelling effect, it is not possible to continuously instill an association with danger through the learning function of wild animals. However, there was a problem that the effect did not last long.

The wild animal repelling device described in Non-Patent Document 1 has a repelling effect on wild animals because it is equipped with a figure made to resemble the shape of an animal feared by wild animals. The device activates when a wild animal approaches, and it also activates at regular intervals, randomly playing various loud warning sounds, and shaking its neck with two glowing eyes, making it difficult to see if it is alive. It is something that threatens wild animals. This wild animal repellent device has achieved a certain level of effectiveness and maintains its superiority in the market. However, the effect is assumed to be dependent on the surrounding environment. If there are feeding grounds that wild animals prefer in the surrounding area or if they have other territories, it is not necessary to stick to the installation location of the device. will not approach. However, in situations where there are no suitable feeding grounds nearby, in areas where wild animals are densely populated, or where the food is a favorite food of wild animals, there is a high possibility that some wild animals will stick to that location; I could see it.

Furthermore, conventional methods for evacuating wild animals tend to target wild animals on the ground, and there is a problem in that there are few methods that are effective in evacuating birds such as crows in the air. .

Furthermore, there are no effective countermeasures against damage caused by wild boars raiding rice fields, feeding damage caused by ducks and other birds in lotus root fields, and damage caused by ducks and other birds feeding on offshore farms (for example, seaweed farms). This is the current situation.

Therefore, the present invention solves the above-mentioned problems of the prior art, and its purpose is to protect wild animals, such as mammals and birds, that are particularly found in paddy fields, lotus root fields, marine farms, etc. where water is plentiful.

FIG. 3 schematically shows the overall configuration of a wild animal repelling device 200 according to a second embodiment of the present invention, and FIG. 4 shows a block configuration of the wild animal repelling device 200 of FIG. 3.

As shown in FIGS. 3 and 4, the wild animal repelling device 200 according to the second embodiment includes a water spouting means 10, a detection means 20, a control means 30B, a moving means 40, and an air jetting means 50. It is equipped with This wild animal repelling device 200 has the same configuration as the above-described wild animal repelling device 100A, except that it includes an air blowing means 50 and the configuration of the control means 30B is different. , the explanation thereof will be omitted.

The control means 30B has a function of controlling the operation of the air blowing means 50 in addition to the function of the control means 30A described above. This control means 30B controls the air blowing means 50 when the detection means 20 detects the approach of a wild animal such as a mammal or bird, and/or at a predetermined time interval. It is configured to be activated to repel wild animals such as mammals and birds.

The air blowing means 50 generates an air flow (air blow) by blowing out compressed air. This air jetting means 50 includes a compressor (not shown) as a supply source, a solenoid valve (not shown) that controls injection, and an air nozzle 51 that jets air (blower air). The air nozzle 51 is connected to a solenoid valve and a compressor via, for example, a flexible hose. Moreover, it is preferable that the air blowing means 50 has at least one air blowing port and is configured to blow out compressed air continuously or intermittently. In the second embodiment, the air jetting means 50 includes a plurality of air nozzles (straight type) having air jetting ports that jet compressed air in different directions. Further, it is more preferable that the air blowing means 50 generates an air flow like an air gun, and is colored so that the shape of the air flow can be visually recognized. Note that the air nozzle is not limited to this. For example, an air nozzle that has a jetting port that can jet simultaneously in multiple directions (vertically or horizontally), an air nozzle that has multiple air jetting ports and jets evenly within a predetermined jetting width, or an air nozzle that has multiple air jetting ports that jet evenly within a predetermined jetting width, or multiple air jetting ports. , and a wide flat air nozzle may be used. In the air nozzle, a large number of ejection holes are installed, and various types such as linear, multi-stage, circular, and angular shapes can be selected. Also, if you use an amplifying nozzle, you can spray it over a longer distance. In actual experiments, you can feel the wind (airflow) from a distance of about 10 meters.

As described above, the wild animal repelling device 200 of the second embodiment includes the water jetting means 10, the detecting means 20, the control means 30B, the moving means 40, and the air jetting means 50. When the detection means 20 detects the approach of a wild animal such as a mammal or bird, the water jetting means 10 and the air jetting means 50 are activated when the wild animal approaches and/or at predetermined time intervals to detect the mammal or bird. By repelling wild animals, such as mammals and birds, it is possible to efficiently intimidate and evacuate wild animals, as well as to exert a wide-area intimidation and repelling effect, thereby achieving sustainability. Therefore, damage to agricultural crops, etc. can be reduced. In particular, it is possible to efficiently evacuate wild animals and birds that appear in rice paddies, marine aquaculture farms, etc. where water is plentiful. Air can be jetted in multiple directions from the air jetting means 50, and an air flow similar to an air cannon can be generated.

FIG. 5 schematically shows the overall configuration of a wild animal repelling device 300 according to the third embodiment of the present invention, FIG. 6 shows a block configuration of the wild animal repelling device 300 of FIG. 5, and FIG. The electrical configuration of the control means 30C is schematically shown.

As shown in FIGS. 5 and 6, the wild animal repelling device 300 according to the third embodiment includes a water spouting means 10, a detection means 20, a control means 30C, a moving means 40, and an air jetting means 50. , a light emitting means 60, and a sound generating means 70. This wild animal repelling device 300 includes a light emitting device 60 and a sound generating device 70, and has the same configuration as the above-mentioned wild animal repelling device 200 except for the configuration of the control device 30C. Explanation of the constituent parts will be omitted.

In addition to the functions of the control means 30B described above, the control means 30C has a function of controlling the operations of the light emitting means 60 and the sound generation means 70 (see FIG. 7 described later). This control means 30C operates the light emitting means 60 and the sound generating means 70 when the wild animals and birds approach and/or at predetermined time intervals when the detection means 20 detects the approach of wild animals and birds. It is designed to repel wild animals such as

The light emitting means 60 is an LED light emitting device composed of a plurality of light emitting elements capable of generating light of a wavelength that is visible to wild animals such as mammals and birds. As the light emitting element, for example, a high brightness LED element with a luminous flux of 120 lumens or more is used. Therefore, wild animals can be made to recognize luminescence not only at night but also during the day. Furthermore, the LED element and its control device can operate at -5°C or lower. That is, a control system including an LED element that can be used outdoors in a cold region is preferable. The number of LED elements used as the light emitting means 60 may be changed as necessary. On the other hand, if the luminous flux of the LED elements is less than 120 lumens, or if the number of LED elements is less than 2, it will be too dark and it will be difficult for wild animals to perceive the light or they will not be able to perceive it. Further, the light emitting means 60 is configured to blink at a frequency of 18 to 24 Hz by the control means 30C. It is effective and more preferable for the blinking frequency of the light emitting means 60 to be around 21 Hz. In addition, the flashing light emission of the light emitting means 60 is controlled to be performed at a stop interval of 15 minutes or more, except when a wild animal appears, together with the sound generating means 70. In addition, by controlling each light emitting means 60 to blink individually, complex blinking of light becomes possible, and it is possible to prevent wild animals from getting used to it. Furthermore, the emitted light color of the light emitting means 60 may be set appropriately as necessary, but light wavelengths mainly in green are not suitable for use in dimly lit environments such as moonlight, since many herbivorous animals are originally nocturnal. However, because they needed to recognize the greenness of grass and trees, herbivores are thought to have a high ability to recognize the 400-600 nm range. Additionally, carnivorous animals can be recognized even at wavelengths of 600 nm or more, but in order to enable both to effectively recognize light, the emission wavelength of the LED element as the light emitting means 60 is preferably in the range of 400 to 600 nm.

The sound generating means 70 generates a threatening sound to intimidate wild animals, and for example, a speaker is used. This sound generating means 70 may be arranged, for example, on the support P, or may be arranged on the drive section. Further, the sound generating means 70 is configured to be able to generate a threatening sound of 80 dB or more. As will be described later, the type (pattern) of the menacing sound generated by the sound generating means 70 can be randomly switched by the sound control section 34 of the control means 30C to make it something that wild animals dislike and are not accustomed to. can. For this reason, a higher repelling effect can be achieved by issuing a sound threat together with flashing lights. In addition, in a demonstration experiment (deer experiment), the effect was weak unless the threatening sound was 80 dB or higher. On the other hand, more than 90% of deer evacuated when hearing a threatening sound of 80 dB or more. 100% evacuated at 90dB threatening sound. In addition, unusual sounds such as the sound of a passing racing car, the sound of a jet plane, and the sound of a chainsaw are highly effective (more than 80%) as threatening sounds, and these also need to be loud (80 dB or more). Note that the sound generating means 70 of the third embodiment is configured to generate a sound of 20 kHz or less.

As shown in FIG. 7, the control means 30C controls the blinking of the blinking pattern storage section 31 that stores a plurality of blinking patterns, the audio data storage section 32 that stores a plurality of audio data of threatening sounds, and the light emitting section 60. a blinking control section 33 that controls the sound generation means 70, a sound control section 34 that controls the sound generation means 70, an air jet control section 35, a water jet control section 36, a movement control section 37 that controls the operation of the moving means 40, It includes a power supply section 38, a CPU 39a, a ROM 39b, and a RAM 39c.

The blinking pattern storage section 31 is composed of a ROM, a RAM, a flash memory, etc., and stores a plurality of blinking pattern data as timings for blinking the light emitting means 60. The blinking pattern data stored in the blinking pattern storage section 31 is not limited to what is stored in advance, and effective blinking pattern data can be added and stored later depending on the type of wild animal.

The audio data storage unit 32 is composed of a ROM, a RAM, a flash memory, etc., and stores a plurality of audio data of threatening sounds output from the sound generating means 70 and used to intimidate wild animals. As a threat sound, for example, use four or more patterns including at least one of the following: an actual wolf voice (howl), an actual deer voice (warning sound), an actual dog voice (bark), a human voice, or a gunshot. have The audio data stored in the audio data storage unit 32 is not limited to what is stored in advance, and effective audio data can be added and stored later depending on the type of wild animal. Note that the audio data may be a recording of an actual voice (real voice) or an artificially created voice.

The blinking control unit 33 controls the blinking patterns stored in the blinking pattern storage unit 31 to randomly switch between blinking patterns in which a predetermined blinking frequency is adjusted. For example, a blinking pattern is randomly selected from among a plurality of blinking patterns and blinked. This can prevent wild animals from getting used to the flashing lights, and can maintain the repellent effect. Note that the blinking control unit 33 can not only randomly switch the blinking pattern, but also perform control to fix the blinking pattern to a predetermined blinking pattern.

The sound control section 34 controls the threatening sound generated by the sound generating means 70. The sound control unit 34 controls the sound generating means 70 to generate a threatening sound of 80 dB or more at stop intervals of 15 minutes or more, except when a wild animal is present. Furthermore, the sound control unit 34 randomly switches and controls the threatening sounds stored in the audio data storage unit 32. For example, a threatening sound is randomly selected from among a wolf's cry, a deer's warning sound, a dog's bark, a human voice, and a gunshot, and is generated by the sound generating means 20. Therefore, it is possible to prevent wild animals from becoming accustomed to the threatening sound, and the repellent effect can be maintained. Note that the sound control unit 34 can not only randomly switch the threatening sound, but also control to fix it to a predetermined threatening sound. Furthermore, the sound control section 34 also controls an ultrasonic generator that is used when there are houses nearby and there is a risk of noise problems.

The air injection control section 35 controls the flow of air generated by the air injection means 50. This air injection control section 35 controls the compressed air from the air injection means 50 to be ejected continuously or intermittently. Note that the air injection control section 35 can cause the air injection means 50 to generate an air flow like an air cannon.

The water injection control section 36 controls the pump 12 and the flow of water generated by the water injection means 10. The water injection control unit 36 controls the water ejection means 10 to eject water continuously or intermittently.

The movement control unit 37 controls the movement means 40 to move within a predetermined range. By moving the moving means 40 in which the water jetting means 10, the detecting means 20, the control means 30C, the air jetting means 50, the light emitting means 60, and the sound generating means 70 are arranged, wild animals can be threatened over a wider range. The movement of the moving means 40 is rotational or linear movement, or movement along any programmed route.

The power supply section 38 is for supplying power to the wild animal repelling device 300. For example, by installing a solar panel and generating solar power, the wild animal repelling device 300 can be installed in a place where there is no electricity. Note that a storage battery or an external power source can be used for the power source section 38.

The CPU 39a controls the overall operation of the wild animal repellent device 300 while using the RAM 39c as a work area according to a control program stored in the ROM 39b.

In the third embodiment, the operating time of the light emitting means 60 and the sound generating means 70 can be set to about 30 seconds to 60 seconds by the blinking control section 33 and the sound control section 34, and the stop time (interval) can be set to 15 minutes or more. preferable. In demonstration experiments, when the stoppage time was about 5 to 10 minutes, deer became accustomed to the system and came closer. If the stoppage time is 15 minutes or more, the effect lasts for more than 5 years. It is recommended that the stop time be desirably 30 minutes. In addition, by ejecting compressed air continuously or intermittently, it is possible to intimidate wild animals and provide contact stimulation at the same time, which is highly effective in repelling wild animals. It is also effective as described above.

As explained above, the wild animal repelling device 300 of the third embodiment includes the water spouting means 10, the detection means 20, the control means 30C, the moving means 40, the air jetting means 50, and the light emitting means 60. , and sound generating means 70. As a result, in addition to the intimidating and repelling effects of the water jetting means 10 and the air jetting means 50, the light emitting means 60 and the sound generating means 70 can efficiently intimidate and evacuate wild animals, making it difficult to learn (get used to). , can maintain a threatening effect for a long period of time.

FIG. 8 schematically shows the overall configuration of a wild animal repelling device 400 according to the fourth embodiment of the present invention, and FIG. The configuration is schematically shown.

As shown in FIG. 8, the wild animal repelling device 400 of the fourth embodiment includes a water jetting means 10, a detecting means 20, a control means 30D, an air jetting means 50, a light emitting means 60, and a sound generating means. 70 and display means 80. This wild animal repelling device 400 has the same configuration as the above-described wild animal repelling device 300, except that it includes a display means 80 and does not have the moving means 40, and the configuration of the control means 30D is different. Therefore, descriptions of similar components will be omitted.

In the fourth embodiment, the water tank 13A of the water spouting means 10 may use water from a pond, a paddy field, or a lotus root field, for example. In the case of marine aquaculture farms, seawater may be used.

As shown in FIG. 9, the control means 30D includes a computer 31D, an LED drive circuit 32D, a display drive circuit 33D, a speaker drive circuit 34D, which are electrically connected to the computer 31D via an input/output interface (not shown). Power is supplied to the water ejection means drive circuit 35D, the air ejection means drive circuit 36D, the computer 31D, the above-mentioned LED drive circuit 32D, the display drive circuit 33D, the speaker drive circuit 34D, the water ejection means drive circuit 35D, and the air ejection drive circuit 36D. A power supply device (not shown) is provided. The LED driving circuit 32D is electrically connected to the light emitting means 60, the display driving circuit 33D is electrically connected to the display means 80, and the speaker driving circuit 34D is electrically connected to the sound generating means 70. The water ejecting means drive circuit 35D is electrically connected to the water ejecting means 10. The detection means 20 is electrically connected to the computer 31D via an input/output interface (not shown). Although not shown, the computer 31D includes a CPU, ROM, RAM, flash memory, etc. in addition to the input/output interface described above, and may also include a wireless or wired communication device.

The storage unit (ROM, RAM, flash memory, etc.) of the computer 31D stores color moving image data of an animal (for example, an apex predator) that threatens wild animals, which is displayed on the display means 80. A plurality of types of moving image data are stored, and the computer 31D can appropriately select and output the data according to, for example, year, season, month, week, day, or time. This moving image data can be added and stored later. Further, even if the image is not necessarily a moving image, it is also possible to reproduce a pseudo moving image by sequentially showing still images like a slide show of still images.

The storage unit (ROM, RAM, flash memory, etc.) of the computer 31D also stores a plurality of blinking pattern data as the blinking timing of the light emitting means 60. The computer 31D can control the stored blinking patterns to randomly switch between blinking patterns in which a predetermined blinking frequency is adjusted. For example, it is possible to randomly select a blinking pattern from among a plurality of blinking patterns and make it blink, thereby preventing wild animals from getting used to the blinking light and making it possible to maintain the repellent effect. Note that the computer 31D can not only randomly switch the blinking pattern, but also control to fix it to a predetermined blinking pattern. The blinking pattern data is not limited to what is stored in advance, and effective blinking pattern data can be added and stored later depending on the type of wild animal.

The storage unit (ROM, RAM, flash memory, etc.) of the computer 31D further stores a plurality of audio data of threatening sounds output from the sound generating means 70 to threaten wild animals. As a threat sound, for example, use four or more patterns including at least one of the following: an actual wolf voice (howl), an actual deer voice (warning sound), an actual dog voice (bark), a human voice, or a gunshot. have The audio data stored in this storage section is not limited to what is stored in advance, and effective audio data can be added and stored later depending on the type of wild animal. Note that the audio data may be a recording of an actual voice (real voice) or an artificially created voice. Furthermore, the sound can be replaced with ultrasonic sound of about 20 kHz to 30 kHz, which is audible to wild animals but inaudible to humans. In this case, since humans cannot hear the noise, it can be used as a countermeasure against noise problems caused by humans in areas such as downtown areas or places close to people's homes.

The computer 31D can control the threatening sound to be generated. For example, it is controlled to generate a threatening sound of 80 dB or more at stop intervals of 15 minutes or more. Further, the threatening sounds stored in the storage unit mentioned above are randomly switched and controlled. For example, a threatening sound is randomly selected from among a wolf's howl, a deer's warning sound, a dog's bark, a human voice, and a gunshot, and is sent to the sound generating means 70 via the speaker drive circuit 34D to be generated. Therefore, it is possible to prevent wild animals from becoming accustomed to the threatening sound, and the repellent effect can be maintained. Note that the computer 31D can not only randomly switch the threatening sound, but also control to fix it to a predetermined threatening sound.

A power supply device (not shown) is for supplying power to the entire wild animal repelling device 400. For example, by installing a solar panel and generating solar power, the wild animal repelling device 400 can be installed in a place where there is no electricity. Note that a storage battery or an external power source can be used as the power supply device.

In the computer 31D of the control means 30D, the CPU controls the overall operation of the wild animal repellent device according to the fourth embodiment, using the RAM as a work area according to a control program stored in the ROM.

In the fourth embodiment, the display means 80 is arranged such that the screens are installed in a plurality of different directions in a horizontal plane, specifically, as shown in FIG. It consists of three liquid crystal flat panels 81. By driving the control and driving device 30D, a color image of an animal that threatens wild animals (for example, an apex predator) is displayed on the screen of these liquid crystal flat panels 81 not as a still image but as a moving image. The images displayed on each liquid crystal flat panel 81 may be the same or different from each other. Wild animals learn because the images of animals are shown in motion, and images of different types of animals, different shapes, different movements, different colors, different brightness, and different brightness can be easily displayed. This makes it possible to sustainably maintain the repelling effect. Note that the number of liquid crystal flat panels 81 may be two (180 degrees apart from each other), four (90 degrees apart from each other), or more. Furthermore, a flat screen or a flat electronic display board may be used instead of the liquid crystal flat panel. Further, as the display means, an organic EL curved panel, a curved screen, or a curved electric light display board may be used.

The order in which the water jetting means 10, the air jetting means 50, the light emitting means 60, the sound generating means 70, and the display means 80 are attached to the column P in the vertical direction is not limited to the order shown in FIG. 8.

As explained above, the wild animal repelling device 400 of the fourth embodiment includes the water jetting means 10, the detecting means 20, the control means 30D, the air jetting means 50, the light emitting means 60, and the sound generating means 70. and display means 80. Accordingly, according to the fourth embodiment, the display means 80 is configured to display an image of an animal that threatens a wild animal (for example, an apex predator) in a still image slide show or a moving image, so that the threatening animal It is possible to give movement to the statue. Furthermore, since the image of the threatening animal is configured to be displayed on the display means 80, it is possible to easily display images of different types of animals, different shapes, different movements, different colors, different brightness, and different brightness. can. Therefore, it becomes difficult for wild animals to learn about images of the threatening animal, and as a result, it becomes possible to effectively and sustainably maintain the repelling effect. Furthermore, the water jetting means 10 and the air jetting means 50 can jet water and air in multiple directions by being configured to jet water and compressed air continuously or intermittently. It is possible to generate air flow such as Therefore, the stimulation can be used to intimidate and repel animals on the ground, and it is also effective against birds such as crows, cormorants, and ducks that engage in aerial combat. In particular, it is possible to efficiently evacuate birds, which are wild animals that often appear in rice fields, lotus root fields, marine aquaculture farms, etc. where water is plentiful.

FIG. 10 schematically shows the overall configuration of a modification of the wild animal repellent device shown in FIG. 8. As shown in the figure, the wild animal repelling device 400A of this modified embodiment includes a water spouting means 10, a detection means 20, a control means 30E, a moving means 40, an air jetting means 50, a light emitting means 60, It includes a sound generating means 70 and a three-dimensional display means 80A.

This wild animal repelling device 400A includes a moving means 40, and is similar to the wild animal repelling device 400 described above, except that the configurations of the control means 30E and the three-dimensional display means 80A are different from the control means 30D and the display means 80. Therefore, descriptions of similar components will be omitted.

The control means 30E controls the three-dimensional display means 80A instead of the display means 80, and its electrical configuration and control processing operation are the same as in the embodiment of FIG. 9, so a detailed explanation will be omitted. do.

In this modification, the display means 80A is a hologram display device that displays an image of an animal in three dimensions, and specifically, as shown in FIG. It is installed in By driving this hologram display device H by the control and drive device, a color three-dimensional image of an animal that threatens wild animals (for example, an apex predator) is displayed on a screen formed by water vapor or fine particles, etc. The video 81a is displayed as a still image slide show or a moving image. Since a 3D still image slideshow or video is displayed, the animal images have movement, and it is easy to display images of different types of animals, different shapes, different movements, different colors, different brightness, and different brightness. Because it can be displayed, it is difficult for wild animals to learn, and it becomes possible to sustainably maintain the repelling effect.

Note that the order in which the water jetting means 10, the air jetting means 50, the light emitting means 60, and the sound generating means 70 are attached to the column P in the vertical direction is not limited to the order shown in FIG. 10.

The configurations and effects of the water jetting means 10, the air jetting means 50, the light emitting means 60, and the sound generating means 70 are the same as those in the above-described embodiment, and therefore their explanations will be omitted.

As explained above, the wild animal repelling device 400A of this modified embodiment includes the water spouting means 10, the detection means 20, the control means 30E, the moving means 40, the air jetting means 50, the light emitting means 60, and the sound emitting means 50. It includes a generating means 70 and a three-dimensional display means 80A. According to this modification, the display means 80A can display a three-dimensional image of an animal that threatens wild animals, and can give movement to the image of the threatening animal. Furthermore, since the image of the threatening animal is displayed on the display means 80A, it is possible to easily display images of different types of animals, different shapes, different movements, different colors, different brightness, and different brightness. can. Therefore, it becomes difficult for wild animals to learn about the image of the threatening animal, and as a result, it becomes possible to effectively and sustainably maintain the repelling effect.

FIG. 11 schematically shows the overall configuration of another modification of the wild animal repellent device shown in FIG. 8. As shown in the figure, the wild animal repelling device 400B of this modified embodiment includes a water jetting means 10, a detecting means 20, a control means 30D, an air jetting means 50, a light emitting means 60, and a sound generating means 70. , and an image projection means (projector) 80B.

This wild animal repelling device 400B has the same configuration as the above-described wild animal repelling device 400, except that the configuration of the image projection means (projector) 80B is different from the display means 80, and therefore, the similar components are , the explanation thereof will be omitted.

The control means 30F controls the image projection means 80B in place of the display means 80, and its electrical configuration and control processing operation are the same as in the embodiment of FIG. 9, so a detailed explanation will be omitted.

Similar to a display, the image projection means (projector) 80B projects images onto a screen (projection sheet) 81B, the ground, walls, rocks, and other objects on which images can be projected (images can be recognized), such as two-dimensional animals, etc. 80a is displayed. The operation and effect are the same as those of the wild animal repelling device 400 described above, so a description thereof will be omitted.

Although FIG. 11 shows an example in which the wild animal repelling device 400B projects onto a screen (projection sheet) 81B, the present invention is not limited to this. Even if you want to project onto the wall of a building, etc., any object that can be projected (an image can be recognized) such as the ground, floor, wall, tree trunk, tree leaves, rock, water surface, etc. is fine. . Furthermore, as the image projection means (projector) 80B, a small portable device such as a smart phone that can project a two-dimensional image or a three-dimensional hologram image that can be carried by humans may be used.

As explained above, the wild animal repelling device 400B of this modified embodiment includes the water jetting means 10, the detecting means 20, the control means 30D, the air jetting means 50, the light emitting means 60, the sound generating means 70, It also includes an image projection means (projector) 80B. According to this modification, the control and drive device outputs a drive signal in response to the detection signal from the detection means 20. As a result, similar to the display type described above, the threat of fountains, air stimulation, and light, sound, and images give wild animals a sense of danger, and the repellent effect is greatly increased. In this wild animal repelling device 400B, since the image projection location and the projection device location are different, it is necessary to control the location where sound and light are generated and the location where air stimulation is applied. There are few problems when projecting from a relatively long distance, but care must be taken when threatening from close range. In order to minimize the sense of incongruity and intimidation, it is necessary to set the projection location and the locations where sound, light, and air are generated close to each other.

In the various embodiments and modifications described above, the display or projection is configured to display an image of a threatening animal, but when no wild animals such as mammals or birds appear, the display or projection Additionally, advertisements, guidance, environmental data, etc. may be displayed. This is particularly effective when displays or projections are installed at unmanned highway entrances, near railway animal intrusion prevention fences, or near residences.

In addition, in the wild animal repelling devices 100, 100A, 200, 300, 400, 400A, and 400B of the above-mentioned embodiments and modifications, the plurality of water spouts 11 of the water spouting means 10 are attached to a plurality of straight pipes, Although an example has been described in which the support is mounted at a predetermined height of the support P, the present invention is not limited to this. The shape and arrangement of the plurality of water spouts of the water spouting means can be appropriately designed as necessary.

Moreover, in the wild animal repelling devices 100, 100A, 200, 300, 400, 400A, and 400B of the above-mentioned embodiments and modified aspects, an example has been described in which a passive infrared sensor or an active infrared sensor is used. It is not limited. For example, a radio wave detector (radar) or a light detector (laser) may be used, or an AI method for identifying wild animals based on images may be used. If the distance capability of the detection means 20 is increased so that it can detect approaching wild animals even at a longer distance, the repellent effect will be further improved. In this case, it becomes possible to sense the approach of wild animals even over long distances, and in particular, it is possible to increase the effect of repelling small animals such as weasels, raccoon dogs, and raccoons, and wild animals such as birds. It is especially effective against small animals such as weasels, raccoons, and raccoons, as well as birds.

Further, in the wild animal repelling devices 100, 100A, 200, 300, 400, 400A, and 400B of the above-described embodiments and modifications, an example has been described in which the detection means 20 is installed on the support P, but the present invention It is not limited to this. It may be installed separately from the support P. Furthermore, the detection means 20 may be installed at multiple locations.

Furthermore, although an example has been described in which the wild animal repelling devices 200 and 300 of the embodiments described above include the moving means 40, the present invention is not limited to this. Instead of providing the moving means 40, a fixed type may be used in which the support P is installed at a predetermined position.

Furthermore, although the wild animal repelling device 100 of the above-described embodiments and modifications has been described as being installed on one support P, the present invention is not limited thereto. For example, as shown in FIG. 12, the plurality of supports P on which the wild animal repelling device 100 is installed may be arranged at regular intervals. In this case, a beam P1 is provided between the pillars P, and the water spout 11 of the water spouting means 10 is also provided in the beam P1. This allows water to be sprayed upwards over large areas for airborne animals such as birds, and downwards for land-based wild animals such as mammals. It is configured. In this way, when protecting a large area, the distance between the supports P will be set depending on the water jetting means 10 and the jetting distance. When protecting a large area, in the case of a fixed type, the arrangement of pillars P senses the approach of wild animals, ejects water, and threatens them with contact stimulation. Birds tend to dislike touch stimuli the most, especially those that touch their feathers. Through actual experience, we have recognized that tactile stimuli tend to have a greater threatening effect than sound or light. Note that in addition to the water spout 11, an air nozzle 51 of the air jet means 50 may be provided on the beam P1. In this case, water or air can be sprayed upwards against animals flying from the air, such as birds.

Naturally, since water has a larger mass than air, it can be ejected over a long distance, and water is a better threat means than air as a means of applying contact stimulation over a long distance. However, water requires a means of replenishment, and if you move or are in an environment with little water, you will not be able to maintain the jet for a long time. In the case of such moving intimidation measures or intimidation devices in environments with little water, air discharge is a better intimidation means. For example, in the case of water environments such as offshore fish farms, rice paddies, and lotus root fields, water jets are suitable, while air jets are suitable for fields, towns, mountain areas, etc. However, if you install a means to supply water and create an environment where water can be intentionally secured, it becomes possible to select water jetting or use it in combination with air jetting.

The present invention is not limited to the above-described embodiments and modifications, but includes within its technical scope various design modifications without departing from the gist of the invention as set forth in the claims. .

INDUSTRIAL APPLICATION This invention can be utilized for the purpose of intimidating and repelling wild animals, represented by mammals and birds, that appear in agricultural lands, ranches, especially rice paddies, vegetable fields, marine aquaculture farms, etc.
