JPH0856533A - Electric shock imparting device for fishing - Google Patents

Abstract

PURPOSE: To make a large-sized fish not resist by electrically shocking the fish or making the fish into a state of apparent death and not to electrically shock a fisherman by mistake in fishing up the large-sized fish. CONSTITUTION: A low-voltage DC electric source 16 is used as input and output of a switching regulator 20 for raising the output of a low-frequency oscillator 21 by a transformer 23 is used as shock imparting output. The output is led to a fishing hook 13 at the tip of a fishing rod 11 and an electrode 15 by two isolated first and second lead wires 12 and 14. When the length of the first lead wire is properly taken, electric resistance between the electrode and the fishing hook being a readily usable value of 100Ω is turned to account to select the value as a threshold value. A changing means 30 for operating switching regulator only when the electric resistance is <= the threshold value and not operating when the electric resistance exceeds the fixed threshold value (e.g. 1kΩ) is installed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing device, and particularly to large fish in the ocean, such as tuna and bonito, which should be easily caught in order to make it easy to catch a fish which is countered with a great force when fishing. The present invention relates to an electric shock imparting device for fishing, which is devised so that an angler does not receive an electric shock due to a high voltage current.

[0002]

2. Description of the Related Art A fish method has been known for a long time, in which an electric shock is applied to a body of water in which a fish inhabits and a fish living therein is captured. I heard that this fishing method is generally a method of applying voltage with the earth as the earth potential, and it sometimes harms humans and animals in the water, and it is said to be regulated by the law as a dangerous method. By the way.

On the other hand, in the fish method for large migratory fish such as skipjack and tuna, the so-called single-line fishing method is used in which those fish are caught from the deck of a ship approaching the school of fish. Shaped fish have a strong resistance against fishing and take a long time to catch, so it has been desired to develop a method of catching as many fish as possible in a short time.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been devised for the purpose of facilitating fishing when an electric shock is applied to a fish hooked on the fishing hook to cause the fish to be in a shock death or asphyxia state. It is a thing. However, if large fish such as skipjack, tuna, etc. are given an electric shock to give them a sufficient shock, the fisherman will also be shocked if it is mistakenly transmitted to the fisherman's body. Since it has an electrical strength that can cause death or asphyxia, the danger must be taken to avoid it.

Further, the fishermen who work on the deck of a ship must have a poor operability so that the fishermen are more burdened than they have been doing so far.

Further, from the viewpoint of its working environment, it is subject to water and rainwater, so it must be safe and operate normally even in such a working environment.

An object of the present invention is to provide an electric shock impact imparting device for fishing, which can surely impart electric shock to the fish when the fish is caught and which does not pose a danger to the human body.

[0008]

The present invention has succeeded in solving the above-mentioned problems by adopting the following means.

As the fishing rod, an example in which a hollow elongated tubular rod made of glass fiber reinforced plastic (GRP) (thus electrically insulating) is used as a fishing rod will be described. An electric wire (referred to as a first conducting wire) having an insulating coating as a fishing line was attached to the tip thereof, and a metal fishing hook was electrically connected to the electric wire and attached to the tip of the fishing line. A part of this electric wire is a wire with the expansion force of stainless steel coated with nylon. An electric shock (voltage / current of one polarity) is applied to the fish on the needle through the fishing line and the hook. In the barrel of the fishing rod, an electric wire (second conducting wire) provided with a second insulating coating is run side by side with the first conducting wire for sending voltage / current to the fishing hook.

A battery or a battery of a fishing boat generator is used as a direct current power source suitable for use on a fishing boat, and a switching regulator for boosting the voltage of the battery to controllably generate an output is provided. The output of the second polarity is sent to the first conductor and the output of the second polarity is sent to the second conductor. The second conductor is the tip of the fishing rod or the first
In the middle of the conducting wire (a part called a wire work), a flexible cylindrical electrode was used for termination. First inside the tubular electrode
It is advisable to accommodate the wire of.

An on / off switch (for example, a push button switch) is provided on at least one of the outputs of the switching regulator, and it is arranged at a position where a fisherman who operates the fishing rod can operate the switch while holding the fishing rod. In other words, when the switch is closed and in the ON state, and the electric resistance between the flexible tubular electrode at the tip of the fishing rod and the fishhook is less than or equal to a predetermined threshold value, in other words, , Only when the switch is on and the fishhook and the tubular electrode are pulled into the seawater, activate the switching regulator so that the switching regulator can generate the electric shock output. , When the above conditions are not satisfied, for example, when the fishing hook is not present or the hook is not in seawater, and the electrical resistance between the hook and the tubular electrode exceeds a predetermined threshold value, the switching regulator does not operate. It was decided to provide a switching means for doing so.

The fishing hook according to the present invention has the same function and effect even if it is replaced with a mortar or a key. Therefore, in the present specification, the fishing hook is used in a broad sense.

[0013]

In the present invention, the high voltage from the switching regulator is guided to the tip of the fishing rod by the two conductors, and the ground is not used as the conductor.

One electrode was arranged in the middle of the wire arrangement, and the other electrode was used as a fish hook. Insulating conductors were used as fishing lines up to the fishing hook, and the fishing lines acted as conductors.

A major feature of the operation of the present invention is, for example, an electrode at a wire rod portion of a fishing rod tip or a first conductor,
The distance between the fishhook and the electrode is, for example, 20 to 100 cm,
Preferably, for example, when the distance is 30 to 40 cm, the distance between both electrodes in seawater is 200 to 500 Ω, preferably 300.
It is supposed to be used that becomes Ω. When this fishing rod is immersed in seawater, it shows a resistance value that is easy to use in the design of an electronic circuit of the order of 100Ω, whereas when the fishing rod is lifted into the air, the fishing rod and fishing line are wet with seawater. However, it is known that there is more than 5 kΩ. In addition, it has been empirically found that the resistance value of the order of 100Ω is never obtained even if a human touches both electrodes. Furthermore, it has been found that a resistance value of 100Ω order can always be obtained in seawater when the distance between both electrodes, that is, the length of a fishing line made of a conductive wire is in the range of 1 m to 10 cm.

Therefore, when switching the switching regulator on and off, whether or not the portion from the electrode to the fishhook is in seawater, that is, as the threshold value, for example, a gentle width in the range of 500Ω or less and 1-2 kΩ or more. Set a value with
It is possible to adopt a device having a switching means that turns off when the resistance is 2 kΩ or more.

By adopting such means, the high voltage / current is output from the switching regulator only when both electrodes are in seawater.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an electrical configuration diagram of an embodiment of the present invention. The part of the fishing tackle 10 on the right side of the drawing is the fishing rod 1
1 and the 1st, 2nd conducting wire 1 inserted in this opening
2, 14 and the first conducting wire 12 hanging from the tip of the fishing rod 11 are attached to the water surface (sea surface) indicated by the chain line at the lower end of the first conducting wire 12, and a fishing hook 13 having conductivity is attached. In the present invention, a stainless steel wire, which is insulation-coated with nylon, is used as the fishing line. The fishing line is therefore the first electrical conductor 12. Actually this nylon coated wire is Wy
A fishing wire commercially available under the trade name of lon was used. This wire has an appropriate color for the coating, and is designed so that it cannot be seen by the fish eye in water. The first conducting wire 12, which is the fishing line, extends from the hand of the fishing rod 11 to the output terminal 27 of the switching regulator 20 for generating a high voltage / current which will be described later, and in the embodiment, a positive voltage is applied. .

A special electrode 15, which will be described in detail later, is attached to the tip of the second conductive wire 14. Along with the first conducting wire 12, a second conducting wire 14 extends from the output terminal 28 of the switching regulator 20 to the electrode 15 at the tip of the fishing rod 11. The second conductive wire 14 is preferably made of the same nylon-coated stainless steel wire as the first conductive wire 12. Alternatively, the first conducting wire 12 and the second conducting wire 14 may be in the form of coaxial cables. Further, the first conducting wire 12 and the second conducting wire 14 may be extended through the inside of the hollow hollow fishing rod 11 made of plastic reinforced with glass fiber. The fishing rod 11 referred to here is intended to facilitate a fisherman to throw a needle and a thread from a shore or a boat toward a sea or a river to a desired place, and is not limited to a rod-like one in that sense. In some cases, the fishing rod 11 may be omitted and the first and second conducting wires 12 and 14 may be directly operated. The electric resistance between the fishing hook 13 and the electrode 15 is tentatively expressed as a resistance R.

The DC power supply 16 is preferably a battery. The switching regulator 20 is of a commonly used type, and in the embodiment, DC 24V is changed to DC 200V.
Boosted to. DC200V is high enough to give an electric shock to large fish such as skipjack and tuna. The output voltage can be adjusted according to the purpose. Low-frequency oscillator 21 with pulse width control circuit for boosting, power FET 2
2, 22 ', a transformer 23, and diodes 24, 24, a capacitor 25 and a diode 26 are used for rectification and smoothing, respectively. A portion 40 surrounded by a chain line in the switching regulator 20 shown in FIG. 1 constitutes a main part of the present invention together with the fishing tackle 10.

The chain line portion 40 will be called switching means. A push-type switch 29 is placed outside the right side portion of the switching means 40 at a position where a fisherman can easily operate the fish while catching the fish. For simplicity of explanation, this switch 29 is assumed to be closed. DC power supply (9
The voltage source of 5 V from V) 30 passing through the regulator 31 and the diode 32 has a first polarity of the switching regulator 20, for example, the positive output terminal 27, the first conducting wire 12,
Fishing hook 13, virtual resistance R, electrode 15, second conducting wire 14,
A closed circuit that returns to the DC power supply 30 through the light emitting element 34 through the switch 29 and the Zener diode (4V) 33 is created. This closed circuit causes the light emitting element 34 to emit light when the resistance R is on the order of 100Ω.
When it is Ω or more, the light emitting element 34 cannot emit light. Of course, even when the switch 29 is open, the light emitting element 3
4 does not emit light. When the light emitting element 34 emits light, the active switch 35 formed of a phototransistor or the like is closed and the transistor switch 36 is turned on, the alarm sound of the buzzer 37 is emitted, and the fisherman outputs a high voltage to the output terminals 27 and 28 of the switching regulator 20. A buzzer sound is displayed to indicate the appearance state, that is, the active state. When the switching transistor 36 is on, the low frequency oscillator 21
Since the B power is supplied and the low frequency oscillator 21 oscillates,
A high voltage is generated on the secondary side of the transformer 23, and a 200V electric shock impact voltage is generated between the output terminals 27 and 28 of the switching regulator 20. Light emitting element 34 and switch 3
The relay in which 5 and 5 are integrated is commercially available, for example, as TL431.

In order to explain the state in which the virtual resistance R becomes, for example, 500Ω or less, or 2 kΩ or more,
A configuration diagram of the fishing rod 11 shown in FIG. 2 will be described. The fishing line portion I has a length of about 300 to 400 mm, and the fishing hook 1
Except for the portion to be crimped with 3, it is covered with a colored nylon insulator that is difficult to see with the eyes of the fish. Also,
On the other hand, it may be a wire that is colored to make it look like a fish to make it attractive, or a nylon insulator that is not colored at all. In the portion II corresponding to the fishing rod 11, the first and second conductive wires 12 and 14 are housed in a shrink tube or employ a braided structure of polyester fiber. The tips of the first and second conducting wires 12 and 14 are connected to the output terminals 27 and 2 of the switching regulator 20.
It is terminated with a terminal or a connector for facilitating connection to the connector 8 (not shown). The total length of the fishing rod is 2
~ 4m is a place where it is easy to use. The second conducting wire 14 has a length of about 100 mm and is made of a stainless steel spring-shaped electrode 1.
5 is electrically and mechanically attached, and the first conducting wire (nylon-coated wire) 12 is insulatedly inserted and fixed to the electrode 15. Since the electrode 15 accommodates the first conducting wire (nylon-coated wire) 12 therein, it preferably has a flexible tubular structure.

The details of the tip of the fishing rod 11 are shown in FIG.
As shown in FIG. 3, an electrode 17A for attaching a wire made of brass is attached to the end portion of the first conducting wire 12, and a conductive ring 17B is formed on the electrode 17. A removable conductive movable hook 12A connected to the upper end of the first conducting wire 12 having the fishing hook 13 attached to the lower end is hooked on the ring 17B. That is, the first
Although the conductor wire 12 is cut in the middle, it is in the form of being connected by the ring 17B and the movable hook 12A. 18A is an electrode for attaching a brass wire, which is electrically connected to the tip of the second conducting wire 14 and has an electrode 15 attached to the lower end thereof.
The upper end of the lead wire 14 is a fitting 1 such as a screw or a hook.
It is attached to the electrode 18A by 8B. That is, the second
Although the conductor wire 14 is also cut in the middle, it becomes a form in which it is connected to the electrode 18A and the fixture 18B.

According to experiments, the electric resistance between the hook 13 and the electrode 15 is in an insulating state when dried in air,
When immersed in seawater, the conductivity of seawater (which is known to be suitable even in fresh water) is 300.
In the length of ~ 400mm, it becomes almost 200-300Ω,
Fishing line length is not a critical factor.
It was confirmed that even if a person grips the electrode 15 and the fishing hook 13 with the bare hand on the ground, the electric resistance can be reduced only to the order of kΩ.

That is, according to the present invention, the switching regulator 20 is turned on only when the switch 29 is turned on and both the fishing hook 13 and the electrode 15 are put into the sea, that is, when the fish bites and pulls the fishing line into the sea. The output terminals 27 and 28 of are activated. In this state, when the fisherman is strongly pulling the fishing line on the fish, the switch 29 is pressed for the purpose of giving an electric shock to the fish.

The output of the switching regulator 20 is
Instead of a flat DC output, a wavy or pulsed output may be used. Therefore, in FIG. 1, the multi-vibrator 38 and the power FET 39 are used to generate a wavy waveform. Purposely high pressure (200-30
It is the DC power supply 1 that generates the wave-like voltage from the direct current (0V)
This is a method adopted to ensure sufficient insulation between the switch 6 and the output of the switch regulator 20 and to reduce the load on the battery power supply.

[0027]

According to the present invention, the electric resistance in seawater is approximately 1 to 1 between electrodes having a dot-like distance of 300 to 400 mm.
It should be on the order of 00Ω, and this resistance value should be a value that is easy to design and work in constructing an electronic circuit.
Focusing on the fact that the resistance is one digit lower than the resistance when a person touches the electrode, the operation threshold of the switching regulator is set. Also, without ground 2
By adopting the power feeding method of this structure, we decided to use a stainless steel wire with an insulating coating as a fishing line that doubles as a conducting wire.

Therefore, it has been possible to realize a human-body-safe, all-weather type device capable of imparting an electric shock only when a large-sized fish which is opposed to being caught is caught from the sea (or generally underwater). It can help improve the productivity of fisheries.

The voltage used is 100 to 300 V, and the application time can be shortened by operating the switch. Therefore, damage to the fish to be caught (for example, breaking the spine or changing the meat quality by electricity). thing)
Can be given. Therefore, the quality of the fish is not deteriorated, and the violence of the fish after the catch is reduced, so that the freshness can be easily maintained.
