Description

[0001]
[Industrial applications]
The present invention relates to a bird and animal repelling device for repelling annoying birds and animals such as wild monkeys, deers, and antelopes that destroy agricultural crops, and crows and stray cats that disperse garbage in a garbage storage area in an urban area.
[0002]
Problems to be solved by the prior art and the invention
Various means have conventionally been proposed as means for preventing damage to birds and beasts that destroy agricultural products. However, monkeys are especially smart and have a good learning ability, so if you simply set up a fence, use a scarecrow, or fire a firecracker, you will quickly get used to it, and if you go over a fence or in the case of a wire fence, Digging under the fence and devouring crops.
[0003]
For this reason, there is a need for a means for preventing the repelling means from becoming ineffective due to the learning ability of the bird and beast.
[0004]
A device that applies a high voltage to the fence to prevent the invasion of monkeys has also been proposed (Japanese Unexamined Patent Publication No. 06-225680). However, only the area surrounded by the fence is protected, and it is difficult to prevent the wide area. In addition, it requires a large amount of expense that is not worth the amount of crop damage.
[0005]
In addition, in order to monitor and pay off monkeys unattended, an energy source, which is an operation source of a sensor and a device for providing additional payment means, is required. However, in mountainous arable land, it is not desirable from the viewpoint of cost, and it is not practical to use the power supply at the garbage dump in the urban area from the viewpoint of burden of charges and maintenance management. Of course, it is desired that the equipment cost must be absolutely low.
[0006]
For this reason, equipment cost is low, and means for repelling unwanted birds and beasts which requires low management costs is required.
[0007]
Therefore, the present invention proposes a novel bird-and-beast repelling device in which even if the learning ability is excellent at a low cost of equipment, it does not approach a predetermined area due to danger.
[0008]
[Means to solve the problem]
A repelling device for birds and animals according to the present invention is a sensor that detects that a bird or animal approaches, an ejection system that ejects a predetermined liquid or gas capable of eliminating birds and animals, and a control unit that controls the operation of the ejection system by sensing the sensor. When the bird or animal to be eliminated approaches a predetermined area, the bird or animal to be eliminated disperses the liquid or gas which is repulsive over a wide area, or the nozzle part of the ejection system is swirled in an unstable state. It is mounted and fixed in a spring shape, and it is provided so that it swings due to external force such as wind or jet reaction, and scatters in an unspecified direction, creating a situation where the target birds and animals are difficult to learn, Keep away from getting used to.
[0009]
Further, the present invention is characterized in that the injection energy source in the device is high-pressure air filled in waste tires, and it is possible to easily obtain operating energy even in a place where there is no power supply, and to effectively use waste tires. And can be used repeatedly by refilling high-pressure air with a compressor.
[0010]
Also, the present invention provides a conductive liquid such as a saline solution for the injection liquid, applying a high voltage between the liquid and the ground, or providing two injection nozzles in parallel to perform two liquid injections. By applying a high voltage between the ejected liquids and applying an electric shock to the repulsion target, the target can be prevented from approaching the area. In particular, unlike a fixed electric wire, a means for approaching the area so as not to receive an electric shock cannot be learned, so that repeated intrusion is not attempted.
[0011]
Embodiment
<First Embodiment> Figs. 1 and 2 show a first embodiment of the present invention. The bird and animal repelling device of the first embodiment comprises a sensor unit 1, a control unit 2, and an injection system unit 3. Be composed.
[0012]
The sensor unit 1 employs a pyroelectric sensor widely used in a security system, and senses the body temperature of an approaching bird or beast (mainly monkey A) without being affected by the outside temperature, plants, or buildings. . Since the sensing range is about 10 meters, it is installed in consideration of the number and arrangement of the injection system units 3 and the injection direction in consideration of the protection target area.
[0013]
The control unit 2 is an electronic circuit that controls the operation of the injection system unit 3 based on the detection signal of the sensor unit 1. The power source 21 of the sensor unit 1 and the control unit 2 uses a dry battery or a storage type solar cell. If necessary, a predetermined pressure sensor or a liquid amount sensor is attached to the injection system unit 3, and control is performed based on a detection value of the sensor.
[0014]
The injection system unit 3 includes a waste tire 31 serving as an injection energy source, a storage tank 32 for the injection liquid B, a solenoid valve 34 interposed in a pipe 33 that supplies high-pressure air from the waste tire 31 to the storage tank 32, An injection nozzle 35 connected to the storage tank 32 is provided.
[0015]
The waste tire 31 has a discharge port incorporated in advance, and the discharge port is connected to a pipe 33 to which an electromagnetic on-off valve 34 is connected. The storage tank 32 may be a PET bottle, which can be used for waste, and the jetting liquid B contained therein extracts a stimulant contained in chili peppers, turtles, etc. which is disliked by animals and is dissolved in aqueous ammonia or an aqueous alcohol solution. Liquid.
[0016]
The injection nozzle 35 is mounted and fixed on an unstable spiral spring 37 provided on a fixed base 36, and is provided so as to swing by an external force such as wind or an injection reaction. The nozzle 35 is provided with a regulating member (for example, a ring body is provided around the nozzle) 38 for limiting the swing range of the nozzle 35.
[0017]
When the sensor unit 1 senses the approach of the monkey A, the electromagnetic valve 34 is opened or closed continuously or intermittently for a predetermined time (several seconds), and the jetting liquid B is jetted vigorously to the sensing area.
[0018]
Since the injection nozzle 35 is supported by the spiral spring 37, when the injection starts, the injection nozzle 35 is swung to the opposite side to the injection direction by the reaction of the injection, and the nozzle 35 performs an unstable swinging movement together with the return operation of the spring. The injection operation is performed while performing.
[0019]
Further, by providing the regulating member 38, the ejection liquid B is not ejected far away from the ejection target area, so that the ejection target area can be specified and waste can be eliminated.
[0020]
Therefore, the landing point of the jet B moves randomly by the swinging motion of the jet nozzle, so that the wild monkey A scatters so that the jet B follows the escape direction, and learns the radiation direction of the jet. I can't do that. Conversely, when the user enters a specific area, he learns that injurious liquid injection is unavoidable, so that he does not approach the area and can prevent monkey damage.
[0021]
The first embodiment is a mountain arable land without an energy source such as electricity, it is possible to build a low-cost repulsion system by using the air pressure of the waste tire of the car as an energy source. is there.
[0022]
In addition, if the remaining amount of liquid in the storage tank 32 is exhausted, the air pressure will not be consumed by stopping the operation of the solenoid valve, the air pressure of the waste tire 31 can be easily monitored with a pressure gauge, and if it decreases, a portable compressor or bicycle Can be easily injected and returned by the air pump, and anyone can easily perform maintenance and management together with replacement of the storage tank (pet bottle) 32 during occasional patrols.
[0023]
Note that the first embodiment of the present invention is not limited to the above-described configuration, and a specific structure is arbitrarily determined as long as an intended purpose is achieved. The mounting position may be provided in the middle of the injection nozzle 34 from the storage tank 32 instead of the pipe line 33. Further, instead of the injection liquid B, the waste tire 31 may be filled with an odorous gas, The injection may be used to repel wild monkeys.
[0024]
Further, the device of the first embodiment may be configured such that a single device independent for each ejection target area is connected to the ejection target area to protect a certain range, or a large number of sensors and a large number of radiations are provided. The entire operation of the system may be controlled by a single control unit. Further, an injection direction control mechanism for the injection nozzle described later may be incorporated.
[0025]
<Second Embodiment> FIGS. 3 and 4 show a second embodiment of the present invention, which realizes repelling birds and beasts by electric shock.
[0026]
Similarly to the first embodiment, the second embodiment includes a sensor unit 4, a control unit 5, and an injection system unit 6.
[0027]
The sensor unit 4 employs a pyroelectric sensor as in the first embodiment. However, since the position of an approaching bird and beast (mainly monkey A) is specified to some extent, a plurality of sensors 41 and 42 are used. , 43... Are arranged, and the position of the animal A to be repelled is specified by sensing by a plurality of sensors.
[0028]
The control unit 5 controls the operation of the injection system unit 6 (operation of the injection liquid pump, nozzle direction operation, high voltage application) based on the detection signal of the sensor unit 1.
[0029]
The injection system unit 6 stores the injection liquid C in a storage tank 61, a nozzle 62 that injects the injection liquid C, an injection direction control unit 63 that determines the injection direction of the injection nozzle 62, and supplies the injection liquid to the injection nozzle 62 at a high pressure. It comprises a pump section 64 and a high voltage power supply 65 for supplying a high voltage.
[0030]
The injection liquid C is a conductive liquid such as saline, and the pump unit 64 may have any type of structure if the injection liquid B can be continuously injected for a predetermined time (several seconds). A piston type that performs injection is suitable.
[0031]
The ejection direction control unit 63 includes a mounting table 632 provided with a horizontal rotation mechanism 631 for the injection nozzle 62, and a tilting mechanism 633 for tilting the mounting table 632 in the vertical direction, and can perform nozzle injection in a desired direction. To do.
[0032]
The high-voltage power supply 65 generates a predetermined high voltage by incorporating an appropriate high-voltage generating circuit. The high-voltage power supply 65 is configured to apply a high voltage between the jet liquid C jetted from the jet nozzle 62 and the ground D. One terminal of the generating circuit is grounded, the tip of the injection nozzle 62 is formed of a conductor, and the other terminal of the high voltage generating circuit is connected.
[0033]
When the approach and approach position of the monkey A are detected by any of the sensors 41, 42,... Of the sensor section 4, the ejection direction control section (horizontal rotation mechanism 631, tilt mechanism 633) 63 is operated. The injection nozzle 62 is directed to the approach position, and the pump unit 63 is operated to inject the injection liquid B toward the monkey A. At the same time that the liquid C comes into contact with the monkey A, a high voltage is applied between the liquid C and the ground D, so that the monkey A receives an electric shock.
[0034]
Therefore, by arranging the repulsion device in the vicinity of the protected area, the monkey A receives an electric shock regardless of the direction from which the monkey A enters, and learns that the monkey A receives the electric shock when entering the specific area. It will not approach the area, and can prevent monkey harm.
[0035]
FIG. 5 shows another example of the second embodiment, in which two jet nozzles 62a are provided in parallel to perform two liquid jets, and a high voltage is applied between the two jet liquids. Is what you do.
[0036]
Therefore, when the ejected liquid comes into contact with the monkey A, the monkey A receives an electric shock due to a high voltage short-circuit between the two jets, and the repelling means is not avoided by the learning ability of the monkey or the like as described above. .
[0037]
Further, in the second embodiment of the present invention, a fixed point injection method without the injection direction control unit of the injection system unit may be used. That is, when a monkey approaches the protected area and a predetermined sensor detects, the injection of the jet liquid (conductive liquid) C causes the spark or the jet liquid C between the jet liquid C and the ground D near the invading monkey. The intervening sparks can scare monkeys, and they will eventually become shocked, so they won't get used to sparks. Therefore, a sufficient repulsion effect can be expected without necessarily having the injection direction control unit.
[0038]
【The invention's effect】
As described above, the present invention provides a sensor that detects that a bird or animal approaches, an ejection system that ejects a predetermined liquid or gas that can be removed by a bird and animal, and a control unit that controls the operation of the ejection system by sensing the sensor. When the birds and beasts to be excluded approach a predetermined area, the liquid or gas that the birds and beasts to be excluded repel is disturbed over a wide area, or the nozzle part of the ejection system is a spiral spring in an unstable state. It is mounted and fixed in a shape, and it is provided so that it swings due to external force such as wind or jet reaction, and scatters in an unspecified direction, creating a situation where the target birds and animals are difficult to learn, and the repelled birds and animals become familiar Thus, it is possible to easily implement the method even in a mountainous area where it is difficult to secure operating energy.
[0039]
Also, the present invention provides a conductive liquid such as a saline solution for the injection liquid, applying a high voltage between the liquid and the ground, or providing two injection nozzles in parallel to perform two liquid injections. By applying a high voltage between the ejected liquids and applying an electric shock to the repulsion target, the target can be prevented from approaching the area. In particular, unlike a fixed electric wire, means for approaching the area so as not to receive an electric shock cannot be learned, so that repeated attempts to intrude are not made.
[0040]
In this way, by repeatedly learning that the approach to the protected area is dangerous without being unmanned, it is possible to permanently repel wild monkeys and the like without killing them.
