Description

[0001]
[Industrial application fields]
The present invention relates to a wildlife repelling device for repelling wild monkeys, deer, antelopes that destroy agricultural crops, and nuisance birds and beasts such as crows and stray cats that devour trash in an urban garbage place.
[0002]
[Prior art and problems to be solved by the invention]
Various means have been proposed as means for preventing damage to birds and beasts that damage crops. However, monkeys are especially smart and have excellent learning skills, so if you simply use a fence, use a scarlet child, or fire a firecracker, you will get used to it immediately. Digging under the fence and eating the crops.
[0003]
For this reason, there is a need for means that the repelling means are not effective due to the learning ability of the birds and beasts.
[0004]
In addition, a device has been proposed to prevent the intrusion of monkeys by applying a high voltage to the fence (Japanese Patent Laid-Open No. 06-225680), but only the area surrounded by the fence is protected and difficult to prevent in a wide area. In addition, a large amount of expenses that are not commensurate with the amount of crop damage is required.
[0005]
Furthermore, in order to monitor and remove wild monkeys unattended, an energy source as an operation source of the device for providing sensors and additional means is necessary. However, it is not desirable from the viewpoint of cost in mountainous farmland, and it is not realistic to use a power source in a garbage dumping site in an urban area from the viewpoint of burden of charge and maintenance management. Of course, it is desirable that the equipment cost should be absolutely low.
[0006]
For this reason, the equipment cost is low, and there is a need for a means of repelling nuisance birds and beasts that requires low management costs.
[0007]
Therefore, the present invention proposes a new bird and animal repelling device that is kept away from a predetermined area due to danger, even if it has low facility costs and excellent learning ability.
[0008]
[Means for solving the problems]
The wildlife repelling device according to the present invention includes a sensor that senses that a wildlife has approached, a jet system that sprays and jets a liquid or gas that heals the exclusion target wildlife, and a control unit that controls the operation of the jet system by sensing the sensor. In the birds and beasts repelling device configured as described above, the injection energy source is high-pressure air filled in waste tires.
[0009]
Thus, a sensor that senses that the birds and beasts have approached, and when the birds and animals to be excluded approach a predetermined area, a liquid or gas that heals the animals to be excluded is sprayed over a wide area so that the animals and animals to be excluded do not approach. In particular, since the injection energy source is high-pressure air filled in waste tires, it is possible to easily obtain operating energy even in places where there is no power source, and the waste tires can be used effectively, and by refilling high-pressure air with a compressor Can be used repeatedly.
[0010]
Further, according to the present invention (Claim 2), the injection nozzle portion of the injection system is placed and fixed in the form of an unstable spiral spring, and is provided so as to swing by an external force such as wind or an injection reaction. By spreading in the direction, it is possible to create a situation where the target wildlife is difficult to learn, and the repelled wildlife will not approach again due to familiarity.
[0011]
[Embodiment]
The figure shows an embodiment of the present invention, and the bird and animal fighting apparatus according to the embodiment includes a sensor unit 1, a control unit 2, and an injection system unit 3.
[0012]
The sensor unit 1 employs a pyroelectric sensor frequently used in security systems, and senses the body temperature of an approaching wildlife (mainly monkey A) without being affected by the outside air 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, and the power source 21 of the sensor unit 1 and the control unit 2 uses a dry cell, a storage type solar cell, or the like. Further, if necessary, a predetermined pressure sensor or a liquid amount sensor is attached to the injection system unit 3, and control based on the detection value of the sensor is also performed.
[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 line 33 for supplying 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 a pipe line 33 having an electromagnetic opening / closing valve 34 connected to the discharge port. The storage tank 32 may be a plastic bottle, and can be used as a waste product. The spray liquid B contained in the storage tank 32 extracts stimulating components that are disgusting by animals such as chili and tortoises, and dissolves them in aqueous ammonia or aqueous alcohol. Liquid.
[0016]
The injection nozzle 35 is placed and fixed on an unstable spiral spring 37 provided on the 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 38 (for example, a ring body is provided around the nozzle) that restricts the swing range of the nozzle 35.
[0017]
Thus, when the sensor unit 1 senses the approach of the monkey A, the electromagnetic valve 34 is opened or closed for a predetermined time (several seconds) continuously or intermittently, and the spray liquid B is ejected vigorously into the sensing area.
[0018]
Since the injection nozzle 35 is supported by the spiral spring 37, when the injection starts, the injection reaction is swung to the opposite side of the injection direction, and coupled with the return action of the spring, the nozzle 35 performs an unstable swinging motion. Injecting while doing.
[0019]
Further, by providing the restricting member 38, the injection target area is not far away from the injection target area, so that the injection target area can be specified, and waste can be eliminated.
[0020]
Accordingly, since the landing point of the spray liquid B is randomly moved by the swinging motion of the spray nozzle, for the monkey A, the spray liquid B is scattered so as to follow in the escape direction, and the radiation direction of the spray liquid is learned. I can't. On the contrary, when entering a specific area, it learns that the injection of disliked liquid is inevitable, so that it does not approach the area and monkey harm can be suppressed.
[0021]
In the above embodiment, a low-cost repulse system can be constructed by using the air pressure of a waste tire of an automobile as an energy source in a mountain cultivated land without an energy source such as electricity.
[0022]
Moreover, if the operation of the solenoid valve 34 is stopped when the remaining amount of liquid in the storage tank 32 is exhausted, the air pressure will not be consumed, and the air pressure of the waste tire 31 can be easily monitored with a pressure gauge. Therefore, anyone can easily maintain and manage the storage tank (pet bottle) 32 by replacing the storage tank 32 during occasional inspections.
[0023]
The embodiment of the present invention is not limited to the above-described configuration, and a specific structure can be arbitrarily determined as long as the intended purpose is achieved. May be provided in the middle of the injection nozzle 35 from the storage tank 32 in place of the pipe line 33. Further, instead of the injection liquid B, the waste tire 31 is filled with malodorous gas, and gas injection is performed. You may also repel wild monkeys.
[0024]
In the above-described embodiment, a single device independent for each injection target area may be configured to protect a certain range by continuing the injection target area, or a large number of sensors and a large number of radiation systems may be protected. The entire operation may be controlled by one control unit.
[0025]
In addition, a number of sensors may be arranged so as to incorporate an injection direction control mechanism for an injection nozzle that detects the approach and approach position of the monkey A and the like and directs the injection nozzle toward the approach position to inject the injection liquid or the like.
[0026]
【The invention's effect】
As described above, the present invention provides a sensor that senses the approach of a bird and beast, an ejection system that ejects a predetermined liquid or gas that can be eliminated by a wild animal, and a control unit that controls the operation of the ejection system by sensing the sensor. This is a liquid that uses high-pressure air filled with waste tires as a jet energy source. Alternatively, gas can be sprayed and sprayed to easily repel birds and beasts.
