Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird and beast harm prevention device for preventing invasion of birds and beasts into a predetermined area.

[0002]

2. Description of the Related Art Conventionally, various kinds of damages caused by invasion of birds and beasts have been known. However, especially in a substation, the birds and beasts become a conductive material and a short circuit or a ground fault occurs. , A birds and animals harm prevention device is used to prevent the birds and animals from entering a predetermined area. As such a bird and beast harm prevention device, for example, a device in which an abnormal magnetic field is generated by a magnet to prevent the birds and beasts from approaching, a device that threatens the birds and beasts with light from a light-emitting body, and a device that threatens the birds and beasts by rotating a windmill Various methods have been proposed, such as objects and those that drive away beasts by making sounds such as a buzzer and a bark.

[0003]

However, none of the above-mentioned methods can achieve sufficient effects. For example, the method of generating an abnormal magnetic field with a magnet has a problem that birds and beasts soon become accustomed to the magnetic field and the effect does not continue. Further, in the method of intimidating with light, when using a luminous body, sufficient effect is not obtained in bright daytime, and when intimidating by reflection of light, on the contrary, it is effective only in bright daytime. There was a problem that I could not get it. Further, the method of intimidating by rotating the windmill has a problem that the effect cannot be obtained unless the wind blows. Further, the method of producing a sound has a problem that it causes noise to the surroundings.

On the other hand, in addition to these methods, there is known a method of forming needles at a place where birds and beasts stop. In this method, because the needles directly touch the birds and beasts to stimulate the tactile sensations of the birds and beasts, unlike the method described above, the birds and beasts do not get used to it immediately, and their effects are impaired depending on the time of day and the environment. There is no problem of noise.
Especially, in the method of forming the needles, the tactile sensation of birds and animals is stimulated, so that the effect of driving off birds and animals is much higher than the method of stimulating the sight and hearing of birds and animals. However, this method is not limited to chasing away the birds and beasts and may damage the bodies of the birds and beasts, which is not preferable in terms of animal welfare.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a bird and beast damage prevention apparatus which can effectively drive away birds and beasts without damaging them.

[0006]

Means for Solving the Problems and Effects of the Invention In the bird and beast damage prevention apparatus according to claim 1, which is made in order to achieve the above object, the detecting means detects that a beast has entered a predetermined monitoring area. To do. Then, when the detection means detects the invasion of the birds and beasts, the stimulating means performs an operation of stimulating the tactile sense of the birds and beasts in the monitoring area, and drives the birds and beasts out of the monitoring area.

According to the above-mentioned bird and beast damage prevention apparatus of the present invention, the bird and beast that has entered the surveillance area is actively driven to stimulate its tactile sensation so that the bird and the beast is driven away from the surveillance area. Therefore, it is possible to effectively drive away the birds and beasts without damaging them.

In other words, even if the structure is to stimulate the tactile sensation of the birds and beasts, it does not itself perform the operation of stimulating the tactile sensations of the birds and beasts, but when it is contacted by the birds and beasts, it stimulates the birds and beasts as a reaction. In a passive configuration such as
Only by being contacted by birds and beasts, it is possible to stimulate the birds and beasts, and accordingly, the tip has a sharply pointed shape, etc.
It may damage birds and beasts.

On the other hand, since the bird and beast damage prevention apparatus of the present invention is configured to positively stimulate the bird and beast regardless of the movement of the bird and beast, it is weaker than the stimulation by the passive configuration. Even then, a sufficient effect can be obtained. In addition, when the invasion of birds and beasts is detected, the action of stimulating the tactile sense of the birds and beasts has the effect of astonishing the birds and beasts due to the change from static to moving.

By the way, as the stimulating means for stimulating the tactile sensation of birds and beasts, it is preferable that a gas or a liquid is jetted to the monitoring area. By doing so, the spraying of gas or liquid is an act that the birds and beasts hate physiologically, and therefore the birds and beasts can be reliably driven off by only giving a weak stimulus to the birds and beasts.

Further, it is more effective if the gas or the liquid is irregularly ejected as in the third aspect. In other words, even birds and beasts with high learning ability are less accustomed to the stimulus, and the effect can be maintained for a long period of time. Further, it is particularly preferable to use air as the gas to be jetted. If it is air, there is no need to prepare it and it is harmless.
Alternatively, for example, helium or the like may be used.

Similarly, it is preferable to use water as the liquid to be jetted. Water is easy to obtain and harmless. Further, for example, sugar water or soap water may be used. Next, the bird and beast damage prevention apparatus according to claim 4 is provided with a stop target which is provided in the monitoring area and in which a bird and beast that has entered the area is stopped, and when the intrusion of the bird and beast is detected by the detection means, stimulation is performed. Means vibrate the stationary object.

That is, in the bird and beast damage prevention apparatus according to claim 4,
By vibrating the stationary object, the tactile sensation of the birds and beasts that have stopped on the stationary object is stimulated. Even with such a configuration, vibrating the object to be stopped is an act that the birds and beasts physiologically dislike, so that the birds and beasts can be reliably driven off by only giving a weak stimulus to the birds and beasts.

[0014] In particular, if the object to be stopped is vibrated irregularly as in claim 5, even a beast having a high learning ability will not easily get used to the stimulation, so that the effect will be exerted for a long period of time. Can be sustained.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a bird and beast damage prevention apparatus according to an embodiment of the present invention will be described with reference to the drawings.
First, FIG. 1 is an explanatory view of a bird-and-animal damage prevention device 20 of the first embodiment installed on a beam 10 provided in a substation.

As shown in FIG. 1, this bird and beast harm prevention device 2
Reference numeral 0 designates a light emitter 3 provided at one end (right side in the drawing) in the longitudinal direction on the upper surface 11 of the beam 10 and emitting infrared rays for bird and beast detection toward the other end (left side in the drawing) in the longitudinal direction.
1, 31 and an infrared sensor provided at the other end in the longitudinal direction of the infrared sensor 32, 32 for receiving the infrared rays for bird and beast detection, and the light emitters 31, 31 and the optical receiver 32 of the infrared sensor on the upper surface 11 of the beam 10. , 32, and a plurality of air injectors 40, 40 for injecting air in a direction facing each other from both ends at positions at both ends in the longitudinal direction of a part sandwiched between the parts 32, 32. In addition, FIG.
The arrangement of each component is shown schematically, and the relative size and detailed shape of each component are not shown. For example, each of the components 31 to 40 constituting the bird and beast damage prevention device 20 can be formed smaller than the beam 10.

Further, the bird and beast damage prevention device 20 is
As shown in FIG. 2, a compressor 50 for compressing air
(In this embodiment, the pressure is 7 to 10 kgf / cm ² ), and an air supply path 51 forming a flow path for supplying the air compressed by the compressor 50 to each of the air injectors 40, 40, .... And an electromagnetic valve 52 that is provided in the middle of the air supply path 51 and that opens and closes the air flow path by electrical power, and is provided on the air supply path 51 downstream of the electromagnetic valve 52.
By changing the air flow area by manual operation from the outside,
An air volume adjusting valve 53 that adjusts the flow rate of air, and a controller 60 that controls the opening and closing of the electromagnetic valve 52 based on information obtained by the infrared sensor are provided. The compressor 50 and the controller 60 are connected to an external power source.

The light emitters 31, 31 and the light receivers 32, 32 of the infrared sensor are located at a position lower than the height of the birds and beasts (ie, the height of the birds and beasts) where the emission or reception of the infrared rays for bird and beast detection is supposed to stay on the upper surface 11 of the beam 10. Infrared for bird and beast detection
At a height that would be hindered by the birds and beasts. Then, the light emitters 31, 31 and the light receivers 32, 32 are arranged on the upper surface 11 of the beam 10 so that the bird and beast detection infrared rays are blocked by the bird and beast wherever the bird and beast stays.
Are provided along the lateral direction of.

Then, the controller 60 detects that the infrared rays for bird and beast detection to be received are blocked by the light receivers 32, 32 of the infrared sensor, so that the bird and beast from the upper surface 11 of the beam 10 in the inter-sensor portion. It detects that a bird or beast has entered the monitoring area, which is a range up to the height at which the infrared rays for detection are emitted and received.

When the controller 60 detects the invasion of birds and beasts, the controller 60 performs a random opening / closing process in which the opening / closing time of the solenoid valve 52 is changed irregularly (randomly) and the opening / closing is repeated. Next, the control process performed by the controller 60 will be described with reference to the flowchart of FIG.

When the controller 60 does not detect the invasion of birds and animals by the above-mentioned procedure by the infrared sensor (S
100: NO), the solenoid valve 52 is maintained in the closed state (S110). Therefore, the air supply line from the compressor 50 to the air injectors 40, 40, ... Is cut off.

On the other hand, when the controller 60 detects the invasion of birds and beasts by the infrared sensor (S100: YES),
Random opening / closing processing is performed to open / close the solenoid valve 52 irregularly (S120). By this processing, the compressor 50 causes the air ejector 4 to operate only when the solenoid valve 52 is open.
Air supply lines to 0, 40, ... Are formed, and air is intermittently and irregularly injected from the air injectors 40, 40 ,. Therefore, as soon as the birds and beasts enter the surveillance area, they are ejected with air and are expelled.
Then, when the birds and beasts are no longer detected by the infrared sensor (S100: NO), the controller 90 causes the solenoid valve 52 to move.
Of the air injectors 40, 40, ...
Stops the injection of air from.

In the first embodiment, the compressor 5
0, the air supply path 51, the solenoid valve 52, and the air injector 4
0, 40, ... And the process of step 120 in FIG. 3 correspond to the stimulating means. That is, the controller 6
0 controls the opening / closing of the solenoid valve 52, and the compressor 50
Air compressed by the air injector 4 via the air supply passage 51
The configuration of jetting from 0, 40, ... Corresponds to the stimulating means. Further, the infrared sensor including the light emitters 31 and 31 and the light receivers 32 and 32 and the process of step 100 in FIG. 3 correspond to the detection means.

According to the birds and beasts damage prevention apparatus 20 of the first embodiment as described above, the birds and beasts are injured by the structure in which air is jetted to the birds and beasts invading the monitoring area to actively stimulate the tactile sensations of the birds and beasts. You can effectively get rid of it.
Moreover, since the air injection is started at the time when the invasion of the birds and beasts is detected, the birds and beasts can be surprised also by the change in the state caused by the air being suddenly ejected from the state where the air is not ejected.

Further, since the injection of air is an act that the beast is physiologically disliked, it is possible to surely drive away the beast without giving any pain to the beast by giving a weak stimulus to the beast. . In particular, since the bird and beast harm prevention apparatus 20 injects air in an irregular manner, it is difficult to get accustomed to the stimulus even for birds and beasts such as crows, which are said to have high learning ability, and the effect is long-term. Can be sustained.

In addition, since the bird and beast damage prevention apparatus 20 uses air as the gas to be jetted, there is an advantage that it does not need to be prepared like other gases and is harmless. Incidentally, in the first embodiment, the air injector 4
Although the air is intermittently and irregularly jetted from 0, 40, ..., The jetting pattern of the air may be other than that. For example, the valve opening time and the valve closing time of the electromagnetic valve 52 may be set to fixed values, respectively, and air may be injected intermittently and regularly. Further, instead of intermittently, the solenoid valve 52 may be maintained in the open state and the air may be continuously injected. And, even in the case of continuously injecting air, the injection speed and the injection flow rate may be changed regularly or irregularly,
Of course, it may be constant.

The gas to be jetted may be something other than air (eg, water vapor). Alternatively, liquid may be ejected. Here, it is particularly preferable to use water as the ejected liquid. Water is easy to obtain and harmless.

Next, the bird and beast harm prevention device 70 of the second embodiment.
Will be described with reference to FIGS. 4 to 6. Note that, in FIGS. 4 and 5, the same components as those in the case of the birds and beasts damage prevention apparatus 20 of the first embodiment (FIGS. 1 and 2) are denoted by the same reference numerals, and therefore description thereof will be omitted. .

As shown in FIGS. 4 and 5, the bird-beast harm prevention device 70 includes a diaphragm 80 which covers from above the inter-sensor portion where the birds and animals are stopped, and a diaphragm based on information obtained by the infrared sensor. And a controller 90 that controls the vibration of 80. The diaphragm 80 vibrates when energized by the controller 90. In the present embodiment, the diaphragm 80 corresponds to the stationary object.

Then, like the controller 60 of the first embodiment, the controller 90 detects that a bird or beast has entered the monitoring area (that is, that the bird or beast has stayed on the diaphragm 80) by the infrared sensor. Also, the controller 90
When detecting the invasion of birds and beasts, the random vibration process is performed in which the vibration time and the stop time of the diaphragm 80 are changed irregularly (randomly) and the vibration and the stop are repeated.

Next, the control process performed by the controller 90 will be described with reference to the flowchart of FIG. When the controller 90 does not detect the invasion of the birds and beasts by the above procedure by the infrared sensor (S200: NO),
The diaphragm 80 is maintained in a stopped state (S21
0).

On the other hand, when the controller 90 detects the invasion of birds and animals by the infrared sensor (S200: YES),
Random vibration processing is performed to vibrate the diaphragm 80 intermittently and irregularly (S220). For this reason, the bird and beast vibrates 8
As soon as it stays at 0, it vibrates the diaphragm 80 and is expelled. Then, when the birds and beasts are no longer detected by the infrared sensor, the controller 90 (S200: N
O), the random vibration processing of the diaphragm 80 is completed, and the diaphragm 80 is maintained in the stopped state again (S210).

In the second embodiment, the diaphragm 80 and the process of step 220 in FIG. 6 correspond to the stimulating means. In other words, the controller 90 causes the diaphragm 80 to
The configuration that vibrates the body corresponds to the stimulating means. Further, the infrared sensor including the light emitters 31 and 31 and the light receivers 32 and 32 and the process of step 200 in FIG. 6 correspond to the detection means.

According to the birds and beasts damage prevention apparatus 70 of the second embodiment, as in the first embodiment, the birds and beasts can be effectively repelled without being damaged. Also, vibrating the diaphragm 80 where the birds and beasts stop is also an act that the birds and beasts physiologically dislike. Therefore, by only giving a weak stimulus to the birds and beasts, the birds and beasts can be surely secured without causing pain. Since the diaphragm 80 is vibrated irregularly, the effect can be maintained for a long period of time.

Although the diaphragm 80 is vibrated intermittently and irregularly in the second embodiment, the vibration pattern of the diaphragm 80 may be other than that. For example, it may be vibrated intermittently and regularly, or may be vibrated continuously instead of intermittently. And when vibrating continuously,
The vibration frequency and the vibration intensity may be varied regularly or irregularly, or may be constant.

Although one embodiment of the present invention has been described above, it goes without saying that the present invention can take various forms. For example, in each of the above-described embodiments, an infrared sensor having a configuration that detects birds and animals by blocking the infrared rays for bird and beast detection is used, but the invention is not limited to this. For example, a configuration in which infrared rays emitted are reflected by birds and animals and received. It may be a thing or the thing etc. which detect infrared rays by the body temperature of a beast. Further, the sensor is not limited to the infrared sensor, and another sensor (for example, an ultrasonic sensor or a weight sensor) may be used.

In addition to the beam 10 in the substation, the present invention can be applied to various places such as a tower or a building, a veranda and the like.
