Description

[Technical field]

[0001] The present invention relates to a bird and animal repellent device that emits light that repels birds and animals. [Background technology]

[0002] Damage caused by wild birds and animals is becoming a problem. For example, damage occurs when crops are eaten by birds and animals, and when birds such as crows and pigeons invade buildings such as warehouses and factories, causing damage such as soiling products and stored items with bird droppings. To deal with the latter, bird-proof netting is installed on the ceilings of buildings.

[0003] Patent Document 1 describes a bird and animal repellent device that projects a sheet-like light. In this bird and animal repellent device, the light sheet projection device is provided so as to be capable of repeatedly reciprocating between a right end position and a left end position. In addition, by adjusting the degree of bending of the projection device fixing part relative to the base fixing part, the projection direction of the light sheet projected from the light sheet projection device can be adjusted on a plane perpendicular to the motion plane of the crank arm that rotates back and forth.

[0004] [Patent Document 1] JP 2009-153427 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, this type of bird and animal repellent device may be installed at a high place, such as near the ceiling inside a building (e.g., a warehouse or a factory). When installed at a high place, after the bird and animal repellent device is installed, the light emission angle in the vertical direction is adjusted by working at a high place so that the light is irradiated toward the place where the birds are staying. However, if it becomes necessary to readjust the light emission angle in the vertical direction, the work at a high place is required again.

[0006] The present invention has been made in consideration of the above circumstances, and aims to realize a bird and animal repellent device that allows the light emission angle in the vertical direction to be adjusted without the need for working at height. [Means for solving the problem]

[0007] The first invention is a bird and animal repellent device comprising a base having an attachment structure, a light emitting unit movably attached to the base and emitting light that repels birds and animals, a first drive unit that rotates the light emitting unit horizontally relative to the base, a second drive unit that rotates the light emitting unit vertically relative to the base, and a remote control having an angle adjustment switch for remotely operating the second drive unit.

[0008] In a second invention, in the first invention, when the bird and animal repellent device is turned on, the light emitting unit emits light while rotating horizontally by the driving force of the first driving unit, with the vertical angle kept fixed.

[0009] The third invention is the first invention, in which when the bird and animal repellent device is turned on, the light emitting unit emits light while changing the vertical angle due to the driving force of the second driving unit, and rotating horizontally due to the driving force of the first driving unit.

[0010] According to a fourth aspect of the present invention, in the first aspect of the present invention, the second drive unit is configured to be able to rotate the rotation shaft of the first drive unit in the vertical direction.

[0011] The fifth invention is the first invention, in which the maximum movable range of the light output unit by the first drive unit is determined as the angular range in which it can be rotated horizontally, and the movable range during use can be set by setting restrictions on the maximum movable range depending on the installation site.

[0012] The sixth invention is the first invention, in which the maximum movable range of the light output unit is determined by the angle at which it can be rotated vertically by the second drive unit, and the movable range during use can be set by setting restrictions on the maximum movable range depending on the installation site.

[0013] According to a seventh aspect of the present invention, in the first aspect of the present invention, in addition to the remote control, an angle adjustment switch is provided on the main body side on which the light irradiation unit is provided. Effect of the Invention

[0014] In the present invention, when the base is attached to a high installation location, light can be emitted from the light emitting unit attached to the base. Here, the present invention is provided with a second drive unit that rotates the light emitting unit vertically relative to the base, and a remote control having an angle adjustment switch for remotely operating the second drive unit. Therefore, after the base is attached by working at a high altitude, the second drive unit can be remotely operated by the angle adjustment switch of the remote control to rotate the light emitting unit vertically relative to the base, thereby adjusting the light emission angle in the vertical direction. According to the present invention, a bird and animal repellent device that can adjust the light emission angle in the vertical direction can be realized without working at a high altitude.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Note that the following embodiments and modifications are merely examples of the present invention and are not intended to limit the scope of the present invention, its applications, or its uses.

[0017] [Configuration of bird and animal repellent device] This embodiment is a bird and animal repellent device 10 that emits light that repels birds and animals. As shown in Fig. 1(a), the bird and animal repellent device 10 includes a base 11 having a mounting structure 33 for mounting to a desired installation location such as a wall or ceiling surface, a light emitting unit 12 that is movably mounted to the base 11 and emits light that repels birds and animals, a first drive unit 13 that rotates the light emitting unit 12 laterally (e.g., horizontally) relative to the base 11, a second drive unit 14 that rotates the light emitting unit 12 vertically (e.g., vertically) relative to the base 11, and a remote control 15 provided with an angle adjustment switch 52 for remotely operating the second drive unit 14.

[0018] The base 11 includes a base body 21 having the above-mentioned mounting structure 33, and a box-shaped casing 22 integrated with the base body 21. The base body 21 includes a flat case mounting part 31 with the casing 22 attached to its front side, and a plurality of legs 32 supporting the case mounting part 31. In this embodiment, the case mounting part 31 and the pair of legs 32 are formed by bending a rectangular metal plate at four points (see FIG. 1(a)). Each leg 32 has an abutment part 32a that comes into contact with the mounting location, and a connection part 32b that extends from the case mounting part 31 to the back side and connects to the abutment part 32a. The abutment part 32a is in the shape of a long, thin plate, and a plurality of through holes 33 for inserting screws are formed as a mounting structure.

[0019] The casing 22 has a flat rectangular parallelepiped shape. Electrical components such as a control board are housed inside the casing 22 (not shown). A first power switch 41 and a first angle adjustment switch 42 are provided on an outer surface (e.g., a side surface) of the casing 22. A transparent cover 25 is attached to the front side of the casing 22. The transparent cover 25 is formed in a substantially hemispherical shape, and covers the light emitting unit 12, the first driving unit 13, and the second driving unit 14.

[0020] The light emitting unit 12 is, for example, a laser device that emits laser light. That is, the light that repels birds and animals is laser light. The light emitting unit 12 may be a device with an output that has an irradiation distance of about 100 m in a dark room (for example, an attic). The light emitting unit 12 may be a device that emits laser light with a predetermined beam spread angle.

[0021] The first drive unit 13 includes a rotating base 16 that rotates about a first rotating shaft 61 that extends in the vertical direction (height direction), and a first motor 17 that rotates the rotating base 16 about the first rotating shaft 61. The first motor 17 is fixed to the casing 22.

[0022] The maximum movable range of the light emitting unit 12 by the first driving unit 13 (the movable range of the rotating base 16) is an angular range in which the light emitting unit 12 can be rotated horizontally, which is 270 degrees or more. In this embodiment, this angular range is set to 300 degrees. However, in an installation location where the bird and animal repellent device 10 does not need to be rotated significantly horizontally, as shown in FIG. 1(b), a restriction is placed on the maximum movable range, and the movable range during use can be set to a range narrower than the maximum movable range. This setting may be performed by a stopper that physically imposes a restriction, or may be performed by controlling the first motor 17 (the restriction may be performed by control).

[0023] In the bird and animal repellent device 10, the side from which the laser light is emitted from the light emitting section 12 at the center position of the above angle range is the "front side" (the right side in FIG. 1(a)), and the opposite side is the "rear side".

[0024] The second drive unit 14 includes a movable member 18 rotatably connected to the rotating base 16 about a second rotation shaft 62 extending laterally, and a second motor 19 that rotates the movable member 18 about the second rotation shaft 62. The movable member 18 has a mounting surface for the light emitting unit 12, and the light emitting unit 12 is fixed to the mounting surface.

[0025] The movable range of the light emitting unit 12 by the second driving unit 14 (the movable range of the movable member 18) is an angular range of 80 degrees or more that allows vertical rotation. In this embodiment, this angular range is 90 degrees, and the angle of the light emitting unit 12 in the vertical direction (the emission angle of the laser light) can be adjusted from the horizontal to an elevation angle of 90 degrees. However, in an installation location where the bird and animal repellent device 10 does not need to be rotated significantly in the vertical direction, as shown in FIG. 1(c), a restriction is placed on the maximum movable range, and the movable range during use can be set to a range narrower than the maximum movable range. This setting may be performed by a stopper that physically imposes a restriction, or may be performed by controlling the second motor 19 (the restriction may be performed by control).

[0026] The remote control 15 is connected to the casing 22 via a connection cord 23. The length of the connection cord 23 is, for example, 3 m or more. In this embodiment, the remote control 15 is a wired type, but it may be a wireless type.

[0027] A power cord 24 is connected to the remote control 15, and power is supplied via the power cord 24. The power supplied to the remote control 15 is supplied to the light emitting unit 12, the first motor 17, and the second motor 19 via a connection cord 23 and a control board (not shown) in the casing 22. The remote control 15 is provided with a second power switch 51 and a second angle adjustment switch 52. The second power switch 51 is operated to the same object as the first power switch 41. The second angle adjustment switch 52 is operated to the same object as the first angle adjustment switch 42.

[0028] [Operation of bird and animal repellent device] Each of the power switches 41, 51 is, for example, a two-contact switch, and can be switched between an ON state and an OFF state. When the power switches 41, 51 are switched to the ON state, the bird and animal repellent device 10 switches to an operating state in which laser light is emitted from the light emitting unit 12. In the operating state, power is supplied to each of the light emitting unit 12 and the first motor 17, but power is not supplied to the second motor 19. In the operating state, the light emitting unit 12 emits laser light while continuously rotating in the horizontal direction (horizontal rotation) by the driving force of the first motor 17 with the vertical angle fixed.

[0029] In the operating state, the first motor 17 switches its rotation direction every certain rotation angle (angle within the angular range in which horizontal rotation is possible (angle of the movable range when in use)), and the light emitting unit 12 also switches its rotation direction every certain rotation angle. For example, in the case of the installation state shown in Fig. 2, the irradiation spot of the laser light L reciprocates along the length direction of the beam (member on which the bird 1 perches) 9 extending along the ceiling surface 6.

[0030] In addition, in the operating state, power may also be supplied to the second motor 19, and the light emitting unit 12 may emit light while continuously rotating in the horizontal direction by the driving force of the first driving unit 13, while changing the vertical angle by the driving force of the second driving unit 14. In this case, in the operating state, whether or not the vertical angle of the light emitting unit 12 is changed by the driving force of the second driving unit 14 may be switched ON / OFF by a switch.

[0031] Moreover, each angle adjustment switch 42, 52 is a three-contact switch and can be switched to a first ON state, a second ON state, and an OFF state. When each angle adjustment switch 42, 52 is switched to the first ON state, the second motor 19 rotates in a first rotation direction in which the elevation angle of the light emitting unit 12 increases. When each angle adjustment switch 42, 52 is switched to the second ON state, the second motor 19 rotates in a second rotation direction (opposite to the first rotation direction) in which the elevation angle of the light emitting unit 12 decreases. By operating each angle adjustment switch 42, 52, the angle of the light emitting unit 12 in the vertical direction (the emission angle of the laser light L) can be adjusted. This adjustment can also be applied to the case where the vertical angle of the light emitting unit 12 is changed in the operating state. In this case, for example, the central angle of the vertical movable range of the light emitting unit 12 (the movable range during use) is adjusted.

[0032] [Installation of the bird and animal repellent device and angle adjustment, and effects of this embodiment] The bird and animal repellent device 10 is installed, for example, near the ceiling surface 6 of a building 5. In Fig. 2(a), the bird and animal repellent device 10 is installed with its front side facing upward. The bird and animal repellent device 10 is fixed to a member 8 fixed to the building 5 by bolts 34 passed through each through hole 33 of the legs 32.

[0033] After the bird and animal repellent device 10 is installed, the angle of the light emitting unit 12 in the vertical direction is adjusted to a desired angle (for example, an angle facing a place where the bird 1 is perched) by the angle adjustment switches 42, 52. This adjustment of the angle of the light emitting unit 12 adjusts the emission angle (magnitude of the elevation angle) of the laser light L in the vertical direction. For example, a worker who installs the bird and animal repellent device 10 while working at a height can adjust the angle of the light emitting unit 12 in the vertical direction by operating the first angle adjustment switch 42.

[0034] However, after this adjustment, it may be necessary to readjust the vertical angle of the light emitting unit 12. For example, if there is no bird 1 at the time of the first adjustment, and a bird 1 flies in after work at height is completed, the manager of the building may want to readjust the vertical angle of the light emitting unit 12 when viewed from the floor side of the building 5.

[0035] In such a case, in this embodiment, a second drive unit 14 is provided which rotates the light emitting unit 12 vertically, and a remote control 15 is provided which has a second angle adjustment switch 52 for remotely controlling the second drive unit 14, so that the angle of the light emitting unit 12 in the vertical direction can be readjusted by remotely controlling the second drive unit 14.

[0036] The bird and animal repellent device 10 can be installed in a variety of positions depending on the conditions of the building 5. For example, as shown in FIG. 3(a), the bird and animal repellent device 10 may be installed on the ceiling surface 6. The bird and animal repellent device 10 is installed with its front side facing downward. In this case, since the light emitting unit 12 of the bird and animal repellent device 10 can rotate laterally within an angular range of 270 degrees or more, by arranging the bird and animal repellent device 10 near the center of the ceiling surface 6, the irradiation spot of the laser light L can be moved over a wide range, and the area of ​​the ceiling 6 where the bird net is to be installed can be significantly reduced.

[0037] Also, as shown in FIG. 3(b), the bird and animal repellent device 10 may be installed on a wall surface 7. The bird and animal repellent device 10 is installed so that its front side faces downward. In this case, in this embodiment, the angle range in which the light emitting unit 12 can rotate vertically is 90 degrees from the horizontal, which is an elevation angle. Therefore, in FIG. 2(a), the emission angle of the laser light L can only be adjusted upward, but in FIG. 3(b), the emission angle of the laser light L can be adjusted downward. Note that, in this embodiment, the angle of the light emitting unit 12 in the vertical direction can only be adjusted on the elevation angle side, but it may also be adjusted on the depression angle side.

[0038] [Modification of this embodiment] The bird and animal repellent device 10 according to this modified example is configured so that the second drive unit 14 can rotate the rotation shaft 61 of the first drive unit 13 in the vertical direction.

[0039] For example, as shown in Fig. 4, the second driving unit 14 may include, in addition to the movable member 18 and the second motor 19, a fixed member 40 fixed to the casing 22, a motor installation unit 45 to which the first motor 17 is fixed, and a third motor 46 that rotates the motor installation unit 45 in the vertical direction relative to the fixed member 40. In this case, the motor installation unit 45 is connected to the fixed member 40 so as to be rotatable about a third rotation shaft 63 extending in the horizontal direction. Note that, as shown in Fig. 5, a configuration in which the movable member 18 and the second motor 19 are omitted may be used.

[0040] According to this modification, it is possible to easily move the irradiation spot of the laser light L by the light irradiation unit 12 two-dimensionally, that is, in the vertical and horizontal directions as viewed from the side. In this case, by controlling the first motor 17 and the third motor 46, in the operating state, the irradiation spot of the laser light L may be moved randomly, the irradiation spot of the laser light L may be moved in a wavy manner, or the irradiation spot of the laser light L may be scanned in the horizontal direction at various angles in the vertical direction.

[0041] [Other variations] In the above-described embodiment, a solar power generation system may be connectable as a power source for the bird and animal repellent device 10.

[0042] In the above-described embodiment, the bird and animal repellent device 10 may further include a timer and a switch for operating the timer (not shown). For example, when this switch is switched to the ON state, the timer operates, and when the timer's set time (e.g., 24 hours) has elapsed, the power is turned OFF. This allows the power consumption to be reduced.

[0043] In the above-described embodiment, the operation may be stopped when the bird 1 is not present in the passing area of ​​the irradiation spot of the light emitted from the light emitting portion 12, and may be resumed when the bird 1 arrives. [Industrial Applicability]
