JP4936252B2 - Intimidating sound generator for birds and beasts - Google Patents

Description

  The present invention relates to a threatening sound generator used for threatening birds and beasts. More specifically, it relates to a threatening sound generator aimed at preventing or invading birds and beasts by means of surprise and intimidating birds and beasts with the same explosion sound as when firecrackers explode. .

  In recent years, with the aim of protecting agricultural products and human safety and life from frequent damage of birds and beasts, various methods have been used to threaten birds and beasts to prevent invasion and to disperse invaded birds and beasts. A proposal has been made.

Broadly speaking, various measures have been taken since ancient times, such as the firing sound of guns, the threat of loud sounds, the threat of light, the release of repellent odors, the model resembling natural enemies, and the scarecrow resembling a doll.
Also, recently, those that represent a large eyeball or those that emit explosive sound at appropriate intervals under the control of a timer by placing an explosion device using propane gas have been put into practical use. In addition, there are some complicated mechanisms that employ electronic control.
Accordingly, large, complex and advanced devices among these devices become expensive devices, and it is inevitable that the running cost is increased.

  In recent years, the development of the national land has progressed, and as a result of the expansion of settlements and cultivated land in undeveloped areas, the habitat of birds and beasts has been narrowed, or due to lack of food by birds and animals due to mountain devastation There are also cases where the habitat area has changed or expanded due to movement of the place of inhabitant and the increase in the number of birds and beasts due to protection.

  As a result, there is a tendency that the chances of encounter with birds and beasts have increased due to the closeness or crossing of the living / living area of people and the habitat of birds and beasts. As a result, there has been a situation in which human livelihood infringement (eg, crop damage, human injury, etc.) due to birds and beasts frequently occurs.

Therefore, various means have been proposed in agriculture, forestry, fishery, and daily life for the purpose of preventing damage from the aforementioned birds and beasts. However, completely preventing damage from birds and beasts in reality continues to be a difficult problem.
Therefore, when these problems are closely observed, in a sense, it has become an aspect of comparing wisdom between birds and animals.
In addition, when these methods that only stop regular sounds and movements are repeatedly implemented, there is a disadvantage that the use of the highly intelligent birds and beasts will become familiar and the effect will be diminished.

  Among them, fireworks and firecrackers have explosion sounds that are similar to the sound of fired hunting guns, and are considered to be less accustomed than other threats. Therefore, a number of threatening means using explosives to emit firecracker-like explosion sounds have been proposed and put into practical use.

For example, a pest control device for flying fireworks has been proposed (see Patent Document 1, page 1).
In addition, there has also been proposed a bird and animal threat device that uses fire ropes to continuously explode firecrackers at regular intervals (see Patent Document 2, page 1).
Shokai 57-41085 JP 2005-261253 A

  These means use fireworks or firecrackers, and in any case use explosives. Fireworks, firecrackers, etc. emit a loud and intimidating sound, which has the advantage that they are difficult to get used to, compared to other threatening means of birds and beasts.

  However, those using explosives are costly, and in order to obtain a certain effect, it is necessary to use a large number of fireworks, resulting in high costs. In addition, if it is necessary to continue threatening acts for a long period of time, it is necessary to prepare and store a large amount of explosive products. In addition to the above cost problems, safety problems such as fireworks explosions during storage occur. .

  In addition to the above, explosive sound generators using acetylene gas by carbide are also widely used, but it takes time to purchase, store and handle carbide and has a bad smell, and its equipment is also large. It has become. The operation cost is not cheap.

  Therefore, there is a need for a threatening means for birds and beasts that emits a large threatening sound similar to fireworks and firecrackers, can be easily manufactured, has no safety problems, and is low in cost. is there.

An object of the present invention is to provide a threatening sound generator for birds and beasts that does not use expensive explosives and generates an explosive sound that is not inferior to the explosive sound of explosives.
As a result of the research, the inventor encapsulated the water-resolved gas obtained by electrolysis of water in a plastic bottle used in beverages, etc., and ignited and exploded it, exceeding the expected (unexpected) large sound. The present invention was completed by finding that an accompanying explosion occurred.

The reason why a result with a large explosion sound is obtained with this configuration is caused by a mixed gas of water splitting gas hydrogen 2: oxygen 1 ratio, or the water splitting gas and the gas are enclosed. Whether the combination with a plastic bottle has such a remarkable effect is not clear.
Therefore, the material of the container of the PET bottle is extremely strong against pulling, resulting from the strength of the container or the preferred shape of the container, or these exhibiting a synergistic effect and changing the process or mechanism of the explosion. It is speculated that it has an explosive sound or an effect of increasing the explosive power.

The present invention uses a plastic bottle used for a commercially available beverage or the like, fills it with a water splitting gas, ignites the gas by electric means, and burns and explodes the filled gas at once. In this way, the explosion sounds intimidate birds and beasts, prevent intrusions, dissipate them, and prevent damage from birds and beasts.
The threatening sound generator of the present invention has an outstanding feature suitable for a threatening purpose because it has an outstanding feature that it produces a large explosion sound regardless of a very simple configuration.

  That is, in a threatening sound generator for birds and beasts, a bottle of a plastic bottle filled with water splitting gas, a cap fitted to the bottle, an ignition means arranged in the bottle, and one end of the cap from the upper side to the lower side A pair of conducting wires that hang down through the cap, and are connected to both ends of the ignition means to suspend the ignition means at the bottle opening, and the other ends are connected to respective poles of the power source. And a threatening sound generator for birds and beasts, characterized in that the ignition means has a wire diameter smaller than that of the conductive wire. And an ignition coil having a wire diameter of 0.1 mm to 0.3 mm and a winding coil-like structure of two or more turns and suspended from one end of a conducting wire at the bottle inner opening. Request 1 is a rattling sound generating device for wildlife according. 2. The bird and beast according to claim 1, wherein the ignition means is an ignition plug for a gasoline engine or a nichrome wire having a wire diameter of 0.3 to 0.5 mm and has a coiled structure of two or more turns. The threatening sound generator for birds and beasts according to claim 1, wherein the applied voltage is 12V.

  According to the present invention, it is possible to obtain a threatening sound generator for birds and beasts with a large explosion sound similar to a firecracker at a low cost, using a material that is readily available. The threatening sound generator of the present invention is intended to generate a threatening sound to birds and beasts, to prevent the invasion of birds and beasts, or to dissipate the invaders, so that animals and animals are not captured or killed. There is no risk of conflict with laws and regulations for the purpose of protecting and protecting people.

A firecracker that uses explosives because it is possible to use commercially available PET bottles as containers for threatening sound generators, and to use gas that is cheap and safe and easy to produce for the gas to be filled and exploded. Compared with, the cost is extremely low. The gas to be filled has an advantage that it can be easily produced with a simple apparatus.
In addition, the threatening sound generator of the present invention does not require a large-scale device, and since it is a small bottle, there is an effect that it can be used at any place without selecting an installation place.
For example, it can be used even when hung on a tree branch, and a normal effect can be expected.

  Compared to other threatening means of birds and beasts, explosion sounds with the same properties as firecracker sounds that are less likely to be used are obtained, which is preferable from the standpoint of preventing habituation. In addition, the 12V battery used for ignition can be from an automobile, and if necessary, it can be used in a mountain, wilderness, or other place where there is no electricity. The threatening sound generator of the invention can be used.

In the event of an explosion, use a protective cage to prevent splashing of bottle fragments due to the explosion.
The fragments of the synthetic resin that are not naturally decomposed are scattered around to prevent environmental pollution and to ensure the safety of the user of the present invention. Further, since the container is a synthetic resin bottle and a synthetic resin cap, an explosion accident due to ignition or the like does not occur during storage, so that the container is extremely safe.

  This threatening sound generator has an excellent feature that emits a large explosion sound with a simple structure, and has a destructive power that is smaller and safer than the explosion sound, is safe, and has an extremely favorable firecracker sound. A threatening sound generator for birds and beasts with explosive sounds with similar properties was obtained.

BEST MODE FOR CARRYING OUT THE INVENTION

The structure and manufacturing method of the threatening sound generator 1 of the present invention will be described with reference to FIGS.
The threatening sound generator 1 of the present invention connects a bottle 3 and a cap 2 (using a beverage PET bottle), a water split gas filled in the bottle 3, an ignition coil 4 attached to the cap 2, a power source and the like. It consists of a conducting wire and a protective cage 14.

  The bottle 3 uses a PET bottle used / sold as a beverage or the like as a gas filling container. Commercially available plastic bottles are available in 2 liters, 1 liter, 500 milliliters, 250 milliliters, 200 milliliters, etc., all of which can be used. Is preferred. In the usual case, a capacity of 2 liters is necessary and sufficient. If it is a bottle made from a pet, it can be used without any trouble even if it is made by any company.

  When the explosion is low, the explosion sound is small. When the explosion is over 2 liters, the explosion sound and the destructive power of the explosion are too great, resulting in a safety problem. It is wise to avoid using it near a private house if it is not suitable and has a large capacity.

  Use water splitting gas as explosive fuel to get explosion sound. This water decomposition gas is obtained as a mixed gas of hydrogen and oxygen when water is electrolyzed. The water splitting gas is easily obtained by a known water electrolysis method and is called so-called squeal. The gas sealed in the bottle 3 is filled in the bottle 3 and sealed with the cap 2 in a state where the gas is collected without applying a gas pressure.

  For gas sampling, filling, and sealing, the water splitting gas generated by the gas generator 9 is placed in an inverted water bottle 3 in a water tank filled with water, and a gas supply pipe is placed in the mouth. If the 10 outlets are inserted, the water in the bottle 3 is pushed out of the bottle and the water and the gas 13 are replaced, so that the water can be easily collected and filled (see FIG. 3). ).

When all the water is pushed out by the gas 13 and the replacement of the water in the bottle 3 with the gas is completed, the cap 3 is sealed to seal the gas 13, and the bottle 3 is taken out as it is.
An ignition coil 4 mounted in the bottle 3 is energized to generate heat up to the ignition temperature, and the enclosed gas is ignited.

Water splitting gas can be easily manufactured at a very low cost by electrolysis of water.
Since it is electrolysis of water, it can be produced continuously by preparing an electric power, an electrolyte mixed with electrolyzed water, and an electrode that is worn by electrolysis.

The ignition coil 4 uses a thin copper wire wound in a coil shape (spiral) a predetermined number of times.
The ignition coil 4 is suspended from the top of the cap 2 from the upper side to the lower side through a pair of conductors 5 and 5a of an anode and a cathode, and is connected to both ends of the ignition coil 4, respectively. It is made into the state suspended by the opening | mouth part in the bottle 3 with the lead wire.
In this case, the protective cylinders 6 and 6a for the two conducting wires may be planted symmetrically at the top of the cap 2.

Further, the ignition coil 4 has a hole 7 of an appropriate size in the body of the bottle 3, the ignition coil 4 is attached, and a synthetic resin plate 8 on which the ignition coil 4 is mounted so as to completely cover the hole 7. Thus, the ignition coil 4 can be attached sideways by sealing.

  In other words, in the manufacturing process of the threatening sound generator, apart from the difficulty of attaching the ignition coil 4, if the ignition coil 4 is in a container in contact with the gas filled in the container at any position of the bottle 3, the ignition coil 4 can be ignited, so there is no particular problem.

  The applied voltage uses a 12V battery. A 12V battery (not shown) for ignition is used in automobiles. If the operator uses the battery of the car or cannot use it, he or she can use the intimidating sound generator 1 of the present invention even in the wilderness or mountains where electricity does not come. can do.

  When the switch is turned on and energized with a 12V power supply, an overcurrent flows through the thin copper wire ignition coil 4, the ignition coil 4 generates heat, rises to the ignition temperature of the gas, is ignited by the gas, and the gas burns at once. explode. For this reason, it is necessary to make the wire diameter of the ignition coil 4 smaller than the wire diameter of the conducting wire. If this condition is not satisfied, an overcurrent flows through the ignition coil 4 and the temperature does not rise to the ignition temperature. I cannot ignite the gas.

  The ignition coil 4 needs to have a wire diameter of 0.1 mm to 0.3 mm in order to reach the ignition temperature with an applied voltage of 12V.

When the coil wire diameter of the ignition coil 4 exceeds 0.3 mm, it is not preferable because it does not rise well to the ignition temperature or it takes time to reach the ignition temperature.
Also, those less than 0.1 mm are not preferable because they are easily burned out and cannot be used repeatedly.
In this case, in order to cause the ignition coil 4 to generate heat and quickly ignite, the number of turns of the ignition coil 4 needs to be two or more. As a result, the ignition coil 4 quickly rises to the ignition temperature.

Moreover, since the ignition coil 4 and the conducting wires 5 and 5a are not burned out or destroyed by explosion, the ignition coil 4 can be used repeatedly. Therefore, the cap 2 equipped with the ignition coil 4 can be placed in a fixed manner on the ceiling portion of the protective cage 14 to be described later, and the conductors 5 and 5a can be used repeatedly until they are damaged.
In order to prevent the conductors 5 and 5a from being easily broken by an explosion, a so-called standard electric cord generally used for home appliances is used as the conductor.

When an explosion occurs, the thinnest and weakest part of the bottle 3 (the part below the neck of the bottle 3) is ruptured and destroyed by the rapid expansion pressure caused by the gas explosion. Will not be destroyed.
Instead of the ignition coil 4 described above, a means for igniting using a small engine ignition plug (ignitions at high voltage and sparks are scattered) may be employed.
Further, a nichrome wire having a wire diameter of about 0.3 mm to 0.5 mm may be used for the ignition coil 4.
The nichrome wire having a wire diameter of less than 0.3 mm is not desirable because it burns out. Moreover, the wire diameter exceeding 0.5 mm is not preferable because it takes time to reach the ignition temperature.

  Needless to say, when the spark plug for the small gasoline engine is used or when the thin nichrome wire is used, the spark plug and the nichrome wire are not damaged by the explosion and can be used repeatedly.

In order to prevent the broken pieces of the bottle 3 from being scattered due to the explosion and to avoid damage to the human body or the like due to the scattered pieces, a fine wire mesh protective gauge 14 having a mesh size of 3 mm or less is used. This prevents scattering and ensures safety.
The protective cage 14 is configured as a hexahedron having a size capable of storing the threatening sound generator 1 using a fine metal mesh, and one side of the protective cage 14 is opened and closed for storing the threatening sound generator 1. The other surface is bonded and fixed by welding or the like. The opening / closing door 15 is provided with a clasp that can be fixed after closing.

The protective cage 14 may have a structure in which a metal mesh is formed in a cylindrical shape, the upper surface of the cylinder is fixed and sealed, and the lower surface is an open / close door.
The point is that it can prevent the broken bottle 3 from popping out, but it should not block the passage of the blast that spouts vigorously, and is preferably a wire mesh.

  The purpose of the protective cage 14 is to prevent the fragments of the bottle 3 destroyed by the explosion from scattering and to ensure the safety of the human body.

Although the threatening sound generator 1 of the present invention produces a large explosion sound, the destructive power of the explosion itself is weak for the explosion sound, and does not have a destructive power that damages an article or hurts a human body.
If the length of the conducting wires 5 and 5a is selected from an appropriate distance that can ensure the safety of the operator from the explosion location, there is no safety problem.

  By the way, when the 2 liter bottle 3 was used, even if it was exploded at a place about 1 meter away using the protective gauge 14, no danger to the body was felt.

  Next, a method of using the threatening sound generator 1 of the present invention will be described.

  The bottle 3 is separately filled with water splitting gas and sealed with the cap 2.

  The bottle 3 is stored in the protective cage 14, the cap 2 is removed, and the cap 3 with the ignition coil 4 fixed to the ceiling portion of the protective cage 14 is screwed onto the cap 2, and the bottle 3 is replaced. Is screwed onto the cap 2 fitted with the ignition coil 4.)

  The power source is a 12V battery (not shown), energized at a point where the operator can ensure safety, heats the ignition coil 4, and the water-splitting gas filled in the bottle 3 When it is ignited, a combustion explosion occurs at once and a loud explosion sound is generated.

  After the explosion, the broken pieces of the bottle 3 destroyed by the explosion remain in the protective cage 14 without being scattered to the surroundings. Incidentally, in the bottle 3 after the explosion, the body part which is the lower part from the neck of the bottle 3 was largely torn, and a small piece (about 3 cm) remained slightly in the cage.

  When intermittent threatening sounds are generated at regular intervals, a large number of bottles 3 filled with gas are prepared with a normal cap that is separately filled with water splitting gas and not equipped with an ignition coil 4 Then, these may be operated in the order described above to be exploded.

  Since the bottle 3 and the cap to be stored after filling with gas are all made of synthetic resin, there is no possibility of an explosion accident due to spontaneous ignition or the like.

  By repeatedly exploding this at appropriate time intervals according to the appearance of the birds and beasts, the birds and beasts can be intimidated to prevent the intrusion or escape the invaders and maintain the damage to the birds and beasts. Can be prevented.

As described above, the bottle 3 filled with water splitting gas and filled with water splitting gas is used, and the gas is not pressurized.
The ignition coil 4 is prepared by winding a copper wire having a wire diameter of 0.3 mm twice in a spiral manner, and preparing a 10 mm long one end with the top of the cap 2 vertically extending from the top to the bottom of the top of the cap 2. A pair of lead wires 5, 5 a (anode, cathode) arranged so as to penetrate are respectively connected to both ends of the ignition coil 4 and suspended from the mouth portion in the bottle 3. The other ends of the conducting wires 5 and 5a are connected to a power source.
