  Hereinafter, a birds and animals intrusion prevention device 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

  In the present embodiment, as shown in FIG. 1, the fence B is provided for the line A which is a no entry area, but for some of the line A, the ground is complicated, etc. The fence B is not provided, and it demonstrates using the example which prevents a birds and animals from invading the track A from the part (intrusion opening C) in which the fence B is not provided.

  The animal and animal invasion prevention device 1 according to the present embodiment is disposed in the vicinity of the entrance C as shown in FIG. 1, and as shown in FIG. 2, a detection unit 2, a plurality of jets 3 and an air pressure source. 4, a power supply 5, and a control unit 6.

  The detection unit 2 detects birds and animals present at a first position P separated by a distance X in a direction away from the track A (outside of the entrance C). In the present embodiment, as shown in FIG. 3, the birds and animals are detected by irradiating infrared rays obliquely downward (angle θ with respect to the horizontal plane) from the position of height H1 toward the first position P. As a detection method, various methods such as a near infrared reflection detection method and a near infrared transmission detection method can be considered.

  As shown in FIG. 1, the plurality of jetted parts 3 (three in the present embodiment) are radially arranged when viewed from the vertical direction, and high pressure air is set so that the birds and animals do not approach the entrance C. It is possible to squirt.

  The central ejection part 3a is provided corresponding to the detection part 2, and as shown in FIG. 3, the ejection part 3a is below the detection part 2 and wants to eject high pressure air of the target bird and beast A high-pressure air is jetted substantially horizontally toward the first position P, which is disposed at the same height H2 as a portion (e.g., near the body).

  When the pressure and distance X of the high pressure air at the time of ejection are set so that the pressure in the range suitable for repelling the birds and animals at the first position P separated by the distance X, θ, H1 and H2 are It is set to have a relationship of tan θ = (H 1 −H 2) / X. The "pressure in a suitable range" is also set by the user in a predetermined range in accordance with the type of bird and the like. Depending on the purpose, for example, it is difficult to repel birds and animals with gentle wind pressure, while the pressure that would cause needless damage to birds and animals is undesirable, so set the pressure in such a range. Conceivable.

  On the other hand, as shown in FIG. 1, the jet parts 3b located on the left and right of the jet part 3a can jet high-pressure air toward the left and right second positions Q of the first position P, respectively. And is arranged at the height H2. In the present embodiment, high-pressure air having the same pressure as the ejection part 3a is ejected from the ejection part 3b, so the high-pressure air ejected from the ejection part 3b is the distance X on the circumferential line Y shown in FIG. In the second position Q, which is far apart, the pressure is in a range suitable for repelling the birds and animals.

  In the present embodiment, the ejection portion 3a corresponds to the "first ejection portion" of the present invention, and the ejection portion 3b corresponds to the "second ejection portion" of the present invention.

  The air pressure source 4 is filled with high pressure air, and supplies high pressure air to the plurality of jet parts 3.

  The power supply 5 supplies drive power to the detection unit 2, the plurality of ejection units 3, and the control unit 6. As the power source 5, it is conceivable to use electric power from a solar panel, a track, a railway facility or the like other than a normal storage battery.

  The control unit 6 causes high pressure air to be ejected from the ejection unit 3a when a bird is detected by the detection unit 2.

  By the way, after the high pressure air is ejected from the ejection part 3a, it is also conceivable that the birds and animals escape toward the entrance C, in which case, as shown in FIG. 1, the first path R or the second path It is considered to pass through L and go to the entrance C.

  Therefore, in the present embodiment, after the high pressure air is ejected from the ejection unit 3, the high pressure air is also ejected from the ejection unit 3b after a predetermined time has elapsed. As a result, the birds and animals are prevented from passing through the first route R or the second route L toward the entrance C, and as a result, the entry to the track A, which is a no entry area, is prevented. Ru.

  The above-mentioned predetermined time is set according to the distance from the first position P to the second position Q, the moving speed of the target bird and animal, and the ejection speed of the high pressure air from the ejection part 3b. Thus, it is possible to apply a pressure in a range suitable for repelling the birds and animals with the high pressure air from the ejection part 3b. The moving speed of birds and beasts is preferably set for each type of target birds and beasts.

  The control by the control unit 6 described above will be described using the flowchart of FIG. 4.

  First, the control unit 6 determines whether the detection unit 2 detects a bird or a beast (S1).

  When a bird and a beast are detected (S1: YES), high pressure air is ejected from the ejection part 3a (S2).

  Then, after a predetermined time has elapsed from the ejection of high pressure air from the ejection portion 3a (S3: YES), the high pressure air is also ejected from the ejection portion 3b (S4).

  As described above, in the animal and animal intrusion prevention device 1 according to the present embodiment, when the detection unit 2 detects a birds and animals, the high pressure air from the ejection unit 3a corresponding to the detection unit 3 toward the first position P Then, after a predetermined time has elapsed according to the moving speed of the birds and animals, high pressure air is jetted from the jet portion 3b toward the left and right second positions Q of the first position P as well.

  According to such a configuration, it is possible to control the moving direction of the birds and animals by the high pressure air jetted from the jet portion 3b, so the bird and beast surprised by the high pressure air jetted from the jet portion 3a intrudes in reverse. It is prevented from jumping toward the mouth C and jumping into the track A which is a no entry area.

  Moreover, in the animal and animal intrusion prevention device 1 according to the present embodiment, the jetted parts 3b are arranged radially around the jetted part 3a.

  According to such a configuration, it is possible to eject high pressure air to a wider area from the ejection part arranged in a small space, so that it is possible to more appropriately prevent the birds and animals from intruding into the intrusion prevention area. It becomes possible.

  In addition, the animal and animal invasion preventing apparatus of the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the scope of the claims.

  For example, in the above embodiment, although the case where three jets 3 are provided is described for ease of understanding, when the entrance C is wide or when the moving direction of the birds and animals is controlled more precisely, etc. , May be provided more.

  Moreover, in the said embodiment, although the detection part 2 was provided corresponding only to the ejection part 3a, you may provide the detection part 2 with respect to some of the some ejection parts 3, or each. In this case, the spouting portion 3 corresponding to the detection portion 2 which first detected the bird becomes the spouting portion 3a (first spouting portion), and the spouting portion 3 adjacent to the spouting portion 3a is the spouting portion 3b (second Of the

  According to such a configuration, the bird / beast can be detected more reliably regardless of where the bird / beast approaches the entrance C. Therefore, it is possible to more reliably prevent the bird / beast from intruding into the infested area. Is possible. In addition, when the ejection part 3a (1st ejection part) corresponding to the detection part 2 which detected the birds and beasts first is located in an end part (when there exists the ejection part 3 adjacent to only one side), the said one side The ejection part 3 adjacent only to becomes the ejection part 3 b (second ejection part).

  Further, in the above embodiment, although the plurality of ejection parts 3 are arranged radially and the high pressure air is ejected in different directions, as shown in FIG. 5, the plurality of ejection parts 3 are arranged side by side, respectively May blow high pressure air in the same direction. In this case, the area where the high pressure air can be jetted becomes narrower than in the case where they are arranged radially, but it is possible to control the moving direction of the birds and animals, so the birds and animals can not enter the invasion prohibited area Be suppressed.

  In this case, it is preferable to make the pressure of the high pressure air jetted from the jet portion 3 b weaker than that of the jet portion 3 a. This makes it possible to apply near-optimal pressure to birds and animals approaching the entrance C, and also to reduce the possibility of unnecessarily damaging the birds and animals by applying extremely strong pressure. It becomes.

  Moreover, in the said embodiment, although the birds-and-animals intrusion prevention apparatus 1 was arrange | positioned in the vicinity of the intrusion opening C, the effect of this invention is acquired even if arrange | positioned somewhat inside or a little outside rather than the intrusion opening C.

  Moreover, although the infrared ray was demonstrated to the example as a detection method by the detection part 2 in this Embodiment, you may employ | adopt other methods, such as an ultrasonic wave and an image identification. In the image identification, for example, a face image of a target beast is stored in the bird and animal intrusion prevention device 1, and the bird and the beast is detected when an image having a matching rate with the face image appears in a predetermined amount on the camera. Conceivable.

  Further, in the above-described embodiment, the predetermined time which is the timing at which the high-pressure air is ejected from the ejection part 3b is the distance from the first position P to the second position Q, the moving speed of the target birds and animals, and the ejection It is set according to the ejection speed of high pressure air from part 3b, but depending on the difference of scaffolding or reduction of the filling amount of high pressure air in air pressure source 4, giving birds and animals a pressure in the range suitable for repelling It is possible that the situation can not be done.

  In consideration of such a situation, a camera may be provided in the birds and animals invasion device 1 to photograph the repel situation, and the predetermined time or the like may be changed according to the repel situation. Furthermore, a pressure sensor corresponding to the ejection portion 3b is provided, the number of times the high pressure air in a pressure range suitable for the repulsion hits the birds and animals is counted, and the predetermined time or the like is changed in consideration of this number. Is also conceivable.

  Further, in the above-described embodiment, as the “the course that a bird or beast that has received high-pressure air from the first ejection portion at the first position according to the present invention will pass when it goes to the intrusion prohibited area” Although the course R and the second course L are listed, a plurality of courses can be considered even with the first course R, for example. In such a case, a route range in which a plurality of possible routes are combined is passed when the birds and animals that have received high-pressure air from the first ejection portion at It can be a path of In the case of FIG. 1, for example, the range of “the course that the birds and animals that have received the high pressure air from the first ejection portion at the first position will pass when going to the entry prohibited area” is, for example, The range between the position P and the entrance C and the width of the entrance C is preferable.

  Further, the “intrusion-free area” according to the present invention is applicable not only to the track but also to other areas such as roads, motorways, houses, and fields.
