Description

[Technical field]

[0001] The present invention relates to a bird and animal repelling device for repelling birds and animals that feed on agricultural crops in a farm field or the like. [Background technology]

[0002] Damage to agricultural crops caused by wild birds and animals is thought to be increasing, as can be seen from the fact that while the area of ​​cultivated land in Japan is decreasing, there has been no significant change in the total area of ​​damage from year to year. Damage to agricultural crops exceeds 17 billion yen per year, and necessary measures are needed. In addition to damage caused by deer, wild boars, crows, monkeys, etc., damage caused by ducks is also serious, and due to their habits, they are particularly active at night, causing damage to agricultural crops in succession. Ducks have the habit of flying into fields at night when agricultural work is not being done to feed, and it is not easy to take measures to repel them.

[0003] Conventionally, devices disclosed in Patent Documents 1 and 2 are known as devices for repelling harmful birds and animals. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility model registration No. 3217837 [Patent Document 2] Patent Publication No. 2020-5532 Summary of the Invention [Problem to be solved by the invention]

[0005] Patent Document 1 relates to a device for repelling harmful birds and animals using laser light, which aims to prevent damage caused by ducks digging up plant sprouts, especially at night, by irradiating a laser pointer back and forth horizontally at a specified time interval and at a specified angle toward a lotus root field. However, in the device of Patent Document 1, the laser pointer only repeats horizontal back and forth irradiation at an angle of, for example, 90 degrees, and the connection shaft of the cylindrical laser pointer 1 and the oscillating motor 2 is connected at a right angle and irradiates only a certain horizontal range fixed therein, so the ducks are only able to repel the ducks by irradiating the laser monotonously, and the ducks gradually stop leaving the field due to the learning effect, since the device only repeats horizontal back and forth irradiation in a 90 degree range. In addition, depending on the lotus root field, for example, the device may be installed on a slope or on an uneven ground, and in such cases, the straightness of the laser light may obstruct the light path, causing the laser light to reach only part of the light path. Furthermore, Patent Document 2 proposes a device that uses a sensor to detect birds and animals approaching a farm field, tracks them, and ultimately repels them from the field. However, this requires special surveillance cameras and image processing control devices, which makes the overall cost of the device and its maintenance costs high, making it poorly cost-effective. In addition, the device requires training in how to use, and so the device cannot be expected to be effective even with simple use.

[0006] The present invention has been made in consideration of the above-mentioned problems of the prior art, and one of its objectives is to provide a cost-effective wide-angle irradiation type bird and animal repellent device that can be manually adjusted in all directions and elevation angles at low cost with a simple configuration. Another objective of the present invention is to provide a user-friendly wide-angle irradiation type bird and animal repellent device that can be easily installed and has an elevation angle adjustment and irradiation range change setting of 180 degrees and 360 degrees by simple manual operations. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a wide-area irradiation type bird and animal repellent device 1, 200, 300 which comprises a rotating device 2 including a rotating table 10 which rotates horizontally around a vertical axis v, a holder mechanism 3 which is installed on the rotating table 10 and holds a cylindrical semiconductor laser device 4, and a cylindrical semiconductor laser device 4 which is supported by the holder mechanism 3 with the horizontal direction as its irradiation range, and the holder mechanism 3 includes a replacement holding section 5 which holds the longitudinal end of the cylindrical semiconductor laser device 4 so that it can be freely inverted and replaced.

[0008] In this case, the holder mechanism 3 preferably includes a swing support part 6 fixed to the rotating table 10 and supporting the replacement holding part 5 so that it can swing freely around the horizontal axis h, and the replacement holding part 5 supported by the swing support part 6.

[0009] Moreover, the replacement holder 5 may have a detachable arm portion 17 for detachably holding the body portion 4a of the cylindrical semiconductor laser device 4.

[0010] In addition, the detachable arm portion 17 may include a plurality of detachable arms 17a, 17b whose tip portions face each other across the insertion gap 18, and an inverted Ω-shaped holder that forms a palm-receiving portion 19 that is continuous with the insertion gap 18.

[0011] In addition, the rotating device 2 includes a storage box 20 that houses at least the rotation drive motor 41 of the rotating table 10 and a control unit 22, and a resilient support device 60 is provided on the underside of the storage box 20 to resiliently support the entire storage box while expanding the irradiation range of the cylindrical semiconductor laser device 4 through vibration.

[0012] Additionally, the resilient support device 60 may include one or more spring members 62 .

[0013] Furthermore, the device may include a vertical support case 70 that is erected on the rotating table and rotates together with the rotating table 10, and also serves to protect the electrical wiring; and an upper semiconductor laser device 90 that is supported by the vertical support case 70 and that reflects laser light from the laser light oscillator 92 on a rotating mirror surface 95 and irradiates it back and forth in the vertical direction to emit a vertical plate-shaped laser light. Effect of the Invention

[0014] The wide-angle irradiation type bird and animal repellent device of the present invention has a simple configuration and is low cost, and it is possible to adjust the elevation angle of the bird and animal repellent laser light and change the irradiation range setting to 180 degrees or 360 degrees around with simple operations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the wide-angle irradiation type bird and animal repellent device of the present invention will be described with reference to the attached drawings. The wide-angle irradiation type bird and animal repellent device of the present invention is used to prevent birds and animals from approaching farm fields, other agricultural crop planting areas, fish and shellfish farming areas, and other areas where birds and animals should not run wild or fly in, by using laser light. In particular, this embodiment is proposed as a repellent device that is installed in a large field, for example, a square of 1 chobu or more, with each side being about 100 meters or more, to prevent damage to lotus root crops, etc., by ducks at night.

[0017] Figures 1 to 8 show a first embodiment of the present invention, and in Figures 1 to 3, a wide-angle irradiation type bird and animal repellent device 1 of the present invention includes a rotation device 2, a holder mechanism 3, a cylindrical semiconductor laser device 4, and a replaceable holding portion 5.

[0018] In this embodiment, the rotation device 2 includes a rotation table 10 that rotates horizontally around a vertical axis, a storage box 20, and a drive mechanism 40. The rotation device 2 is a rotary drive means that rotates horizontally around a vertical axis v the rotation table 10 on which at least the cylindrical semiconductor laser device 4 is mounted, and the rotation table 10 has, for example, a horizontal plane or any other mounting surface 10a suitable for mounting the cylindrical semiconductor laser device 4. As shown in Figures 1, 4, and 5, in this embodiment, the rotation table 10 is supported on the storage box 20 via a bearing portion 11 so as to be rotatable in any direction around the vertical axis.

[0019] In the embodiment, the storage box 20 is a casing member that supports the rotation table 10 and supports the horizontal rotation of the cylindrical semiconductor laser device 4 around the vertical axis, and houses therein a drive unit 21 and a control unit 22, which will be described later. In the embodiment, the storage box 20 is configured as a hollow box-shaped three-dimensional case having six sides, but the three-dimensional shape and form can be set arbitrarily.

[0020] In this embodiment, the cylindrical semiconductor laser device 4 is a laser light irradiating means that generates coherent light with a high optical energy frequency and phase by light amplification by stimulated emission of radiation caused by recombination of electrons and holes in a semiconductor element of a P, N junction, and is configured in a cylindrical shape having a laser light emitting part. In the embodiment, as shown in the figure, the semiconductor laser device 4 is formed in a substantially cylindrical shape, and its body side part is detachably attached to the replacement holding part 5 and is held so that its longitudinal direction can be reversed and replaced. The semiconductor laser device 4 does not necessarily have to be configured in a cylindrical shape, and can be configured in a square, pentagonal, hexagonal cylindrical shape, other polygonal cylindrical shape, or any other three-dimensional shape that is long in one direction.

[0021] 1, 3, 4, 5, and 6, the holder mechanism 3 is a holding means for a cylindrical semiconductor laser device that holds a cylindrical semiconductor laser device 4, and in this embodiment, the holder mechanism 3 includes a replacement holding section 5. The replacement holding section 5 is a holding means for holding the cylindrical semiconductor laser device 4 so that the longitudinal direction can be manually reversed and replaced. Since the longitudinal direction can be manually reversed and replaced, for example, by preparing two holder mechanisms 3 for holding a cylindrical semiconductor laser device that performs laser light irradiation by 180 degrees horizontal rotation, 180 degrees horizontal irradiation or 360 degrees full circumference laser light irradiation can be easily switched, and the device can be operated according to a specific installation location for bird and animal repelling. When two cylindrical semiconductor laser devices are supported with the irradiation directions reversed, 180 degrees horizontal rotation of the turntable 10 enables 360 degrees irradiation while performing 180 degrees irradiation on the front and back, respectively, and in this case, the driving device and control configuration are simplified, and the device cost can be kept low. In this embodiment, two holder mechanisms 3 are installed at positions spaced apart as opposing outer edges on a disk-shaped rotating table 10 so that the longitudinal directions of the cylinders of the laser device are parallel to each other. Three or more holder mechanisms 3 including the replacement holding unit 5 can be installed on the rotating table 10.

[0022] In the figure, in this embodiment, the holder mechanism 3 includes a swing support part 6 and a replacement holding part 5. The swing support part 6 is a swing support means fixed on a rotating table 10 and supporting the replacement holding part 5 so as to be swingable around a horizontal axis h, and includes a bracket 13 erected on a base 12. In this embodiment, as shown in Figs. 4(a) and 4(b), the bracket 13 has a plurality of bearing walls 14 perpendicular to the horizontal axis h. Then, a swing shaft 16 is provided in the horizontal axis direction for threading the bearing walls 14 of the bracket 13 and the legs 15 of the replacement holding part 5 with the legs 15 of the replacement holding part 5 inserted between the bearing walls 14, thereby allowing the replacement holding part 5 to swing around the horizontal axis h. In this embodiment, the replacement holding part 5 can swing around the swing shaft 16 by 45 degrees each to the left and right from the vertical direction (see Fig. 5(b)), within a total range of 90 degrees. While there is no problem if the angle can be changed by swinging within this range in terms of device use, swinging within a swing range of 90 degrees or more may be used. This allows the cylindrical semiconductor laser device 4 to instantly perform horizontal rotation around the vertical axis v, swing rotation around the horizontal axis h that allows adjustment of the elevation angle direction of the device 4, and changing and setting the horizontal rotation range by inverting the device 4 in the longitudinal direction of the replacement holding part 5 with a simple operation.

[0023] 1 to 6, in this embodiment, the replacement holding part 5 has a detachable arm part 17. The detachable arm part 17 is a part that directly receives and holds the body side part of the cylindrical semiconductor laser device 4 when holding the cylindrical semiconductor laser device 4 so that the longitudinal side of the cylindrical semiconductor laser device 4 can be freely inverted and replaced, and in this embodiment, it is composed of two detachable arms 17a and 17b whose tip parts face each other across an insertion gap 18, and an inverted Ω-shaped holder that forms a palm receiving part 19 that is continuous with the insertion gap 18.

[0024] In the embodiment, the replacement holding part 5 is made of, for example, rubber or elastic plastic, and the tips of the first and second detachable arms 17a and 17b have a certain degree of elasticity and are set to expand the insertion gap 18 when pressure is applied and to return to the original spacing of the insertion gap 18 when pressure is released. Therefore, when the body side part 4a of the cylindrical semiconductor laser device 4 is strongly pressed manually against the tips of the detachable arms 17a and 17b in Fig. 4(a) and (b), both tips are pushed open and enter the receiving part 19, and the cylindrical semiconductor laser device 4 is stably held. In addition, since the cylindrical semiconductor laser device 4 can be easily pulled out manually while being held by the receiving part 19, the irradiation direction can be easily and quickly switched by reversing the longitudinal direction.

[0025] As described above, the rotating device 2 is a rotary drive means for horizontally rotating the rotating table 10 around the vertical axis v, and in the embodiment, includes the drive mechanism 40. In Figs. 1, 2, 3, and 9, the drive mechanism 40 is provided in the storage box 20, and includes at least a drive motor 41, a motor drive circuit 42, and a controller 43 as a control unit. In this embodiment, a light / dark sensor 44, a timer 45, and a limit switch changeover unit 46 are further included and installed. The timer 45 is set to irradiate for 30 seconds in one operation, for example, at intervals of 5 minutes, 10 minutes, and 30 minutes. In addition, the control unit 22 receives a changeover signal from the limit switch changeover unit 48 and supplies a right or left rotation command signal to the motor drive circuit 42 to rotate the drive motor 41 right or left accordingly.

[0026] In the embodiment, the drive motor 41 is, for example, a DC direct current motor, and the motor shaft 41a and the lower end of the rotating table 10 are connected to, for example, a shaft not shown, so that the rotating table 10 rotates horizontally by the rotation of the motor. In FIG. 8, a protrusion 46 is attached to the end of the rotating shaft of the motor as a dog that rotates following the rotation of the motor, and limit switches 47a, 47b are provided at each of 90 degrees on one side of the 180 degrees rotation range. The dog 46 rotates integrally with the rotating table 10. When the protrusion 46 at the end of the rotating shaft strikes the striker of one of the limit switches 47a, b, the DC motor rotates repeatedly while reversing the range of 180 degrees. The drive mechanism 40 is connected to an external power source such as a solar battery device not shown, and the power is turned on to the controller at a specified time via an external schedule timer. At that time, if the day / night signal of the light / dark sensor 44 is night, the interval timer 45 is started. Then, the drive motor 41 and the cylindrical semiconductor laser device 4 perform repeated operations until the timer output signal is released. When the timer output signal is released, the repeated operations are stopped for the designated interval time. Then, after the interval time has elapsed, the drive motor 41 and the cylindrical semiconductor laser device 4 perform repeated operations again. The above series of operations is repeated unless the external schedule timer turns off the power.

[0027] The wide-area irradiation type bird and animal repellent device 1 of the embodiment is preferably used by being supported at a certain height on the outer edge of a field via supporting stakes, poles, or other supports. It can also be installed in the center of the field in a plan view and irradiated with laser light in all directions at 360 degrees.

[0028] 7 shows the switches, terminals, etc. attached to one side of the storage box 20, with 50 being a selector switch for setting the operation time of the interval timer 45 to 5, 10, or 30 minutes, 51 being a terminal for connecting an external speaker, 52 being an operation indicator light that lights up only while the automatic illumination or inspection switch is pressed, 53 being an inspection switch that can perform the same operation as the automatic illumination only while the switch is pressed when the light sensor is at night, 54 being a light sensor for distinguishing day and night, 55 being an option switch, and 56 being a cable gland that is an outlet connector for pulling in electric wires.

[0029] Next, the operation of the wide-area irradiating bird and animal repellent device of the first embodiment will be described. In this embodiment, as shown in FIG. 2, two cylindrical semiconductor laser devices 4 are provided on the outer edge of the rotating table 10 at positions equidistant from the center and 180 degrees apart in the circumferential direction so that their longitudinal directions are parallel to each other. In FIG. 5(a), the cylindrical semiconductor laser device 4 is held with its body part 4a at the longitudinal center held by the detachable arm part 17 so that the cylinder is oriented horizontally. In FIG. 5, only one side (the right side of FIG. 4(a)) of the two cylindrical semiconductor laser devices 4 is shown, and the left direction in the figure is set as the irradiation range of the laser light. At this time, if the other side is also set as the irradiation range in the same direction, when the rotating table 10 rotates horizontally, for example, half a turn, the two cylindrical semiconductor laser devices 4 will irradiate laser light in the horizontal direction of 180 degrees. When irradiating the wide-angle irradiation type bird and animal repellent device 1 with laser light in the entire circumference direction, the barrel 4a of the cylindrical semiconductor laser device 4 is manually grasped from the state shown in FIG. 5(a) and pulled out from the detachable arm part 17, and then inverted in the longitudinal direction as shown in FIG. 5(c) so that the laser beam is directed in the opposite direction and then attached. As a result, the two cylindrical semiconductor laser devices 4 are each irradiated with a 180-degree range on the opposite side by the 180-degree horizontal rotation of the rotating table 10, and it is possible to irradiate the entire 360-degree circumference range around the wide-angle irradiation type bird and animal repellent device with laser light to perform bird and animal repelling action. Note that FIG. 5(b) shows the swing range of the swing shaft 16 described later, which is set to be swingable, for example, 45 degrees on each side in the vertical direction. The swing range can be set to be swingable within any range.

[0030] In addition, since the angle of the replacement holder 5 can be changed and set in the elevation angle direction via the swing support part 6, the horizontal direction and the elevation angle direction of the irradiation range of the laser light can be freely changed and adjusted and set. At that time, the irradiation range in the elevation angle direction can also be changed and adjusted and set in the reverse direction.

[0031] Fig. 6 is a schematic diagram showing the laser light irradiation direction of the cylindrical semiconductor laser device 4 by two holder mechanisms 3 installed in parallel on a rotating table 10, for example, and Fig. 6(a) shows the positional relationship of the replacement holding part 5 and the swing support part 6 with respect to the same swing axis 16, but Figs. 6(b), (c), and (d) show the swing axis 16 in a shifted position for easier viewing. Fig. 6(a) shows two cylindrical semiconductor laser devices 4 set so that the irradiation direction is the same radial direction, and Figs. 6(b), (c), and (d) show an example in which the cylindrical semiconductor laser devices 4 are set by inverting the longitudinal direction and replacing them so that the irradiation ranges are 180 degrees opposite to each other.

[0032] Next, a second embodiment of the wide-angle irradiation type bird and animal repellent device of the present invention will be described with reference to Figs. 10 and 11. The same members as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0033] In the wide-angle irradiation type bird and animal repellent device 200 of the second embodiment, a resilient support device 60 is provided on the underside of the storage box 20 of the rotating device 2 of the wide-angle irradiation type bird and animal repellent device 1 of the first embodiment. The resilient support device 60 is a resilient support means that resiliently supports the entire storage box 20 on the underside of the storage box 20, and amplifies vibrations generated by mechanical contact and friction between members caused by the driving of the rotating device 2, particularly when the rotating base 10 of the rotating device 2 rotates, when the rotation direction is switched during the forward / reverse reversal operation of the driving motor 41, and other times, to expand the elevation angle direction irradiation range of the cylindrical semiconductor laser device 4 installed on the upper side of the rotating base 10. In particular, the vertical amplitude is amplified to expand the irradiation range of the field scene, thereby improving the bird and animal repellent function.

[0034] In Fig. 10 and Fig. 11, a receiving plate 61 is disposed below the lower surface of the storage box 20 with a space therebetween. The receiving plate 61 is disposed approximately parallel to the lower surface of the storage box 20. A spring member 62 is interposed between the lower surface of the storage box 20 and the receiving plate 61 at a position corresponding to each of the four corners of the storage box 20. The resilient support device 60 includes the spring member 62, and resiliently supports the entire storage box 20 on the lower surface side of the storage box 20. Due to the resilient support force of the spring member 62, the projection 46 strikes one of the limit switches 47a, 47b to horizontally rotate the rotating table 10 in the opposite direction, and the irradiation range of the laser light from the cylindrical semiconductor laser device of the replacement holding unit 5 is greatly amplified in the direction of expansion through the micro-vibration generated when the projection 46 strikes one of the limit switches 47a, 47b to horizontally rotate the rotating table 10 in the opposite direction, thereby improving the bird and animal repelling function. 10, the underside of the storage box 20 and the receiving plate 61 are connected by a screw shaft 64 with an adjustment nut 63, and the spring member 62 is attached so that the screw shaft 64 penetrates a central gap of the spring member 62. Reference numeral 65 denotes support legs of the receiving plate 61, which are attached to the four corner positions of the receiving plate. In the embodiment, four spring members 62 are provided at the four corner positions of the underside of the storage box 20, but the number and attachment positions are not limited. Also, in the embodiment, the resilient support device 60 is a spring member, but a rubber material or other resilient material may be used.

[0035] Next, a third embodiment of the wide-angle irradiation type bird and animal repellent device of the present invention will be described with reference to Figs. 12 to 14. The same members as those in the first and second embodiments are given the same reference numerals, and detailed descriptions thereof will be omitted.

[0036] The wide-angle irradiation type bird and animal repellent device 300 according to the third embodiment is configured by providing a resilient support device 60 on the underside of a storage box, and further mounting an upper semiconductor laser device 90 via a vertical support case 70 on a rotating platform 10. In Figs. 12 and 13, the vertical support case 70 is erected in the approximate center of the rotating platform 10 on the storage box 20, and an operating lever section 71 and a monitor camera 72 are mounted on the upper part of the vertical support case 70, and further the upper semiconductor laser device 90 is mounted on the upper part of the monitor camera 72. In this embodiment,

[0037] In Fig. 14, the upper semiconductor laser device 90 includes a housing 91, a laser light oscillator 92 installed in the housing 91, a rotary reflecting mirror device 93 that continuously reflects the laser light emitted from the laser light oscillator 92 while rotating around a horizontal axis, and a slit hole 94 that is long in one direction and is provided on a wall surface 91a of the housing 91 and passes the laser light reflected by the rotary reflecting mirror device 93. The upper semiconductor laser device 90 is configured to include a vertical support case 70 that is erected on a rotating table 10 and rotates together with the rotating table 10 and also serves to protect electrical wiring, a laser light oscillator 92 supported by the vertical support case 70, and a laser light from the laser light oscillator 92 that is reflected by a rotating mirror surface 95 and reciprocated in the vertical direction to emit a vertical plate-shaped laser light. In Fig. 14, 95 is a reflecting mirror, and 96 is a rotating axis of the reflecting mirror. In this embodiment, the housing 91 is rotatable around a horizontal axis 97 and can be locked at any rotation position to irradiate the laser light.

[0038] In the wide-angle irradiation type bird and animal repellent device 300 of the third embodiment, the vertically elongated plate-like laser beam Φ formed after passing through the slit hole 94 is scanned and moved in a sector-like manner laterally in the emission direction by the horizontal rotation of the turntable 10, making it possible to emit or irradiate the laser beam in a planar manner over the entire target farm field, cultivation area, etc. This realizes linear laser light irradiation over a 180-degree range or a full 360-degree range of the device by the replaceable holding part 5, as well as circumferential sweep irradiation by a vertical cross-sectional linear laser light in space, making it possible to significantly improve the bird and animal repellent function with an inexpensive configuration.

[0039] In the wide-angle irradiation type bird and animal repellent device 300 of the third embodiment, the arrangement, number, angle, etc. of the mirrors of the rotary reflector are not limited to those in the embodiment, but may be any that can form a vertical plate-shaped laser beam.

[0040] In addition, in the wide-area irradiation type bird and animal repellent devices of the first and second embodiments, as in the device of the third embodiment, support piles 80 or the like may be fixed to the underside of the receiving plate 61 or the storage box 20 and the support piles may be driven directly into the ground of the field, etc., to support the device at a certain height above the ground.

[0041] The wide-area irradiation type bird and animal repellent device realized in the above embodiment includes a rotating device including a rotating table that rotates horizontally around a vertical axis, a holder mechanism that is installed on the rotating table and holds a cylindrical semiconductor laser device, and a cylindrical semiconductor laser device that is supported by the holder mechanism with the horizontal direction as the irradiation range. The holder mechanism includes a replacement holding part that holds the cylindrical semiconductor laser device in a manner that allows it to be freely inverted and replaced, thereby rotating the cylindrical semiconductor laser device horizontally around the vertical axis, and supporting, for example, one of the multiple cylindrical semiconductor laser devices so that the longitudinal direction is inverted and replaced to irradiate laser light in 180-degree opposite directions, so that laser light can be irradiated in 360-degree directions all around by simply rotating the rotating table horizontally around the 180-degree direction around the wide-area irradiation type bird and animal repellent device, and the bird and animal repellent function can be performed in all directions all around by simply moving the rotating table back and forth only in a 180-degree range in the horizontal direction. In addition, the longitudinal direction of the cylindrical semiconductor laser device can be inverted and replaced manually in an extremely simple and short time. This also enables the rotation table to irradiate a wide area of ​​laser light by repeatedly rotating it 180 degrees using a DC motor and a limit switch, etc., which allows for a simple device configuration and a low cost for the entire device. In addition, by installing multiple holder mechanisms and cylindrical semiconductor laser devices on the rotation table, the irradiation range can be set in any direction, making it possible to effectively irradiate a wide area of ​​laser light.

[0042] In addition, the holder mechanism includes a swing support part that is fixed to the rotating table and swingably supports the replacement holding part around a horizontal axis, and the replacement holding part supported by the swing support part, so that it is possible to adjust the irradiation position in the elevation angle direction of the cylindrical semiconductor laser device that irradiates laser light directed in the horizontal direction, for example, via the swing support part, and it is possible to realize the adjustment setting of the direction of laser light irradiation for the entire surrounding space. In particular, the angle of laser light irradiation can be easily set in fields with many uneven areas and large differences in elevation, which can improve the bird and animal repelling function.

[0043] In addition, the replacement holding portion has a detachable arm portion that holds the body portion of the cylindrical semiconductor laser device in a freely detachable manner, so that the body portion of the cylindrical semiconductor laser device can be manually grasped to easily and quickly reverse the laser light irradiation direction.

[0044] In addition, the detachable arm section is provided with a plurality of detachable arms whose tip ends face each other across the insertion gap, and an inverted Ω-shaped holder that forms a receiving portion that is continuous with the insertion gap, thereby enabling the cylindrical semiconductor laser device to be detachably held in the replacement holding section.

[0045] In addition, the rotating device includes a storage box that houses at least the rotation drive motor and control unit of the rotating table, and a resilient support device is provided on the underside of the storage box that resiliently supports the entire storage box while expanding the irradiation range of the cylindrical semiconductor laser device through vibration.This allows the cylindrical semiconductor laser device to be horizontally rotated at any angle in the elevation direction while amplified and irradiated with the amplitude of the micro-vibration at a triangulation irradiation position located, for example, 100 to 200 meters away, thereby enhancing the bird and animal repellent function.

[0046] Furthermore, by configuring the resilient support device to include one or more spring members, it is possible to specifically realize the resilient support function of the rotation table and, in turn, the cylindrical semiconductor laser device.

[0047] Furthermore, by including a vertical support case that is erected on the rotating table and rotates together with the rotating table, and that also serves to protect the electrical wiring, and an upper semiconductor laser device that is supported by the vertical support case and irradiates vertically in a sector-like reciprocating manner around the horizontal axis, it is possible to irradiate a vertically long, plate-shaped laser beam via the upper semiconductor laser device in addition to the cylindrical semiconductor laser device into the surrounding space while maintaining a simple structure, thereby further enhancing the bird and animal repelling function.

[0048] As described above, the wide-area irradiation type bird and animal repellent device of the present invention has a low-cost device configuration, is highly effective in repelling birds and animals, and is easy to operate, allowing the user to easily set the laser light irradiation range, angle, number of operating devices, etc. [Industrial Applicability]

In addition, the present invention can effectively exert a repellent function against nighttime feeding damage caused by birds such as crows, and other animals such as deer, wild boars, crows, and monkeys.
