Thereafter, it is reported to a fisherman waiting on fishing boats, and the fisherman recovers the fishing gear device along with the tunas being caught by the help of the position information signal.SELECTED DRAWING: Figure 6

Description

  The present invention relates to a fishing gear device for trolling used in the fishery field and a fishing method using the same.

There are a variety of large fishes that inhabit the ocean, but the most common are the salmon and coral. These are particularly preferred by Japanese people and are regarded as important fishery resources with high economic value.
These fishing grounds are also widely distributed in various parts of the world, although there are differences between the sea and the ocean, and fishing activities targeting them are actively carried out in many countries and regions.
In addition to these fishing methods, such as the longline fishing method and the swirl fishing method, which try to capture a large amount of salmon and bream at once, there is also a single fishing method that targets big fish individually.
And in the case of the former fishing method, especially the lathe net fishing method, even if there are no fishing periods and no fishing sea areas, they are still in the stage of young fish before the fish grows sufficiently and has high economic value. Risks that could lead to overfishing remain, and there are circumstances that are considered problematic in terms of depletion of fishery resources and economic loss.

However, in the case of a single-fishing fishing method that has great value in catching a big fish, the damage to the fish caught is relatively small, so even if the amount of captured individuals is small, each item is a high-quality product. May be traded at high prices. In this sense, this single fishing method is considered to have advantages that cannot be overlooked in terms of avoiding the load on fishery resources and economic loss.
This single fishing method is also popular in the field of leisure fishing that is conducted in relatively warm and calm waters. For example, fishermen are engaged in rough winters in rough winters, such as carp fishing in Oma Town, Aomori Prefecture. There are situations where you are faced with a great danger and are doing it.
In addition, as the cost structure in these fisheries, the fuel oil cost related to ship operation occupies a large proportion. Therefore, if this fuel cost can be reduced, the fishing method of single fishing is also considered from the viewpoint of the environmental cost that is being emphasized nowadays. Can be more environmentally friendly than ever.

As for non-patent literature 1, with a small unmanned aerial vehicle (drone) flying in the air, the fishing line (fishhook) with bait is transported to the offshore school of fish and the fish hooked on the fishhook is used. Attempts to fish with fishing rods have been made as part of leisure fishing. A number of ideas such as Patent Document 1 and Patent Document 2 have been proposed regarding means for transporting a fishhook to a distance that cannot be reached by throwing fishing using a normal fishing rod. Similar to the attempt of Non-Patent Document 1, these are summarized as an idea of using a machine to carry a fishhook to a distance and catching the caught fish with a fishing rod.
In addition, as something that seems to be related to some of the constituent elements of the present invention, it is different from the fishing gear device of the present invention, but the idea of an autonomous underwater navigation device that assumes scientific exploration and hazardous material processing ( Patent Literature 3) has been proposed so far.

“If you can catch it, you can use a drone to carry bait and make a single tuna fishing breakthrough” (http://karapaia.livedoor.biz/archives/52217103.html), dated May 6, 2016

  It is safer, has a high accuracy of catch, enables efficient fishing, and can be expected to be effective in reducing fishery risks and expenses, such as reducing fuel oil consumption associated with fishing boat operations, especially for large fish It is to realize a fishing gear device for a trolling fishing method and a fishing method using the same.

The present invention comprises a power source supply device and a propulsion device, and receives and transmits the position information signal to the outside while receiving the position information signal by the position information signal receiving and transmitting device, In accordance with the navigation route set in the storage device, unmanned navigation aircraft equipped with a control device for autonomous navigation while controlling the propulsion device pulls fish capturing means to capture large fish such as corals, It is an unmanned navigator (hereinafter referred to as “trolling drone”) as a fish trap.
A fishing line with a fishhook is a typical means for catching fish to be pulled.
In other words, this trolling drone captures large fishes such as rods and rods hanging on the hooks by trolling the hooks with bait and pseudo bait via fishing lines such as wires and tegs. It is a fishing gear device using this.

  When the fish hook swallows the fishhook and a fish pull exceeding the preset force is sensed by the fish shin sensing device via the fishing line, the airbag device is activated, and the force of the airbag activates it. The braking device that has been folded up will expand in the shape of an umbrella in the water. The rapid movement of the airbag device and the braking device interlocked with the movement of the rod that tries to escape from the fishhook, and the reaction force against the movement of the rod and the like due to the resistance of the inflated airbag and the open braking device Give rise to This reaction force automatically has a hooking effect to ensure that a swallowed fishhook bites into the fish body, so that a general angler operates a fishing rod against a fish shin Therefore, it is possible to prevent the fishhook from escaping from the hung fish such as a hail.

  In this case, it is not assumed that the brake device will be activated immediately upon detection of the fish belief (around) by the fish bean detection device, and the airbag will be delayed and deployed after a predetermined time has elapsed since the fish bean detection by the timer. You may make it do. This is the same as when a fisherman who feels a fish belief (hit) performs a hooking action (matching) by pulling a fishing rod suddenly while measuring the timing of swallowing bait according to the fish species he is aiming for. By automatically generating a hooking effect at an appropriate timing according to the fish species, it is possible to more reliably catch the fish that is a prey.

Then, when the air bag device is activated, a notification device for notifying a fisherman who fishes using this trolling drone that a fish has started is activated, the control device stops the propulsion device, and the trolling drone is autonomous. End navigation and stop.
After making the trolling drone sail autonomously, the fisherman waiting for the fishing result and waiting on the fishing boat etc. receives a report from the trolling drone that the fish has caught, and also relies on the position information signal sent from the trolling drone The stop location will be identified, headed to that point, and the trolling drone will be collected along with the captured fish such as carp.

An unmanned trolling drone performs trolling while autonomously navigating the route set in consideration of the migration route of fish and the location of the school of fish, and when a dredging or the like is applied, it detects the fish faith (per) and detects the air bag When the device is activated (in some cases, the airbag device is activated at a time difference by a timer) and the braking device that opens like an umbrella suddenly operates, a reaction force against the pulling of the bag or the like occurs, and an automatic hooking operation is performed. It will be performed and large fish such as cormorants will be captured automatically and reliably.
And since the reporting device is activated at the time of capture and informs the fisherman of the fishing results, the fisherman must wait on the fishing boat or wait for another task until receiving the report. It is sufficient to realize efficient fishing.
Therefore, compared with the case where a large fishing boat is operated and trolling is performed while moving on the sea, the amount of fuel oil consumption can be greatly reduced, and cost and environmental load can be reduced.
Also, in some cases, in the rough seas in the severe winter season, in other cases, many fishing boats gather in the narrow waters where the fish such as sharks migrate and the school of fish is concentrated. Compared to the situation where you want to cut the heel, there is an advantage that the safety and comfort of fishing are greatly improved.

It is a perspective view of a trolling drone (state before operating a braking device). It is an association figure of each apparatus of a trolling drone. It is a perspective view of the trolling drone (state after operating the braking device). It is a reference figure regarding the mechanism in which a braking device opens like an umbrella. It is a reference figure (state before capture) which shows the use situation of a trolling drone. It is a reference figure (state after capture) which shows the use situation of a trolling drone.

Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a trolling drone 1 according to the present invention as viewed obliquely from behind and above.
About the trolling drone 1, from a functional viewpoint, the rough structure can be roughly divided into two parts, namely, the main body part 2 and the tail part 3, and can be roughly divided into two parts. However, this division is for convenience only.
The front part which becomes the direction side (arrow side in the figure) in which the trolling drone 1 navigates is the main body part 2, and various devices for enabling the trolling drone 1 to autonomously navigate, such as a storage device and a control device. It is stored inside (internal devices that are not visible from the outside are not shown in FIGS. 1 and 3). Further, the propulsion device 6 that generates the propulsive force of the trolling drone 1 is installed integrally with the body 4 or separated from the side of the body 4 as shown in FIG.
And after the main body 2 of the trolling drone 1, a traction device 11 that pulls a fishing line 12 to which a fishhook with bait or pseudo bait is tied, or a trolling that opens in an umbrella shape when fish catches on a fishhook. A tail portion 3 including a drone 1 and a braking device 15 that suppresses the movement of fish is connected. The tail portion 3 is pulled underwater in accordance with the autonomous navigation of the main body portion 2.

Next, each apparatus which comprises the main-body part 2 and the tail part 3 is demonstrated sequentially.
Note that the relationship diagram of these devices is as shown in FIG.
Further, as will be described later, the fish detection device 14, a part of the airbag device 16 (for example, an inflator), the notification device 22 and the timer 23 are not necessarily installed in the tail portion 3. It may be on the side. In FIG. 2 and the following description, for convenience of explanation, the main body portion 2 and the tail portion 3 are divided in this way.
First, it is the main body 2.
The body 4 of the main body 2 shown in FIG. 1 is not easily rusted and has a light weight such as GFRP (glass fiber reinforced plastic) or CFRP (carbon fiber reinforced plastic) in order to satisfy the strength that is not easily broken by external water pressure or impact. It is desirable to use a robust material. The outer shape is formed with an overall smooth aspect in order to reduce fluid resistance during navigation. Needless to say, the materials and structure of the body 4 do not allow water to penetrate in order to protect the various devices stored inside from being wet. It is necessary to be carried out with precision. In that sense, it is considered effective to make the design specifications of the parts constituting the body 4 consisting of as few parts as possible that have been molded in a predetermined shape in advance.
Moreover, for the stable navigation of the trolling drone 1, the whole should be designed while paying attention to the weight balance of the front and rear and the left and right including the main body 2 and the tail 3.

Inside the body 4, as shown in the association diagram of FIG. 2, a power source supply device 5 such as a battery or a fuel oil tank, and a power source such as electricity or fuel oil supplied from the power source supply device 5. A propulsion device 6 composed of a motor and an engine driven by a motor, a screw propeller, a water jet propulsion device, a rudder and a ballast tank for changing the course and depth of the trolling drone 1 if necessary, and the like. A storage device 7 capable of storing a navigation route (including depth), a position information signal receiving / transmitting device 8 such as a GPS (Global Positioning System) signal, and a received position information signal are used to measure the position of the aircraft. And a control device 10 for appropriately controlling the propulsion device 6 so that the aircraft can self-activate in accordance with the navigation route set in the storage device 7. Make.
As described above, the propulsion device 6 can be installed integrally with the body 4, or can be separated from the body 4 and installed on the side surface thereof as shown in FIG. 1.
The storage device 7, the transmission / reception device 8, and the control device 10 other than the propulsion device 6 are operated by electricity. When the power source supply device 5 is a battery, the power supply is supplied from the battery. In addition to the power supply supply device 5, a dedicated battery for operating these devices should be installed separately from the propulsion battery as a power source supply device 5 Is also possible.

The power source supply device 5 is a device for supplying electricity to the motor or supplying fuel oil to the engine in order to generate the power of the trolling drone 1, that is, propulsive force. It consists of a combination with auxiliary equipment including electric cords and fuel oil pipes.
In the case of a battery, in addition to the specification of a replaceable cartridge type, it is also possible to make it a specification that can be charged from the outside. The same applies to the fuel oil tank, but from the viewpoint of its weight and ease of handling, it seems that a specification that allows fuel oil to be replenished from the outside by providing a fuel filler port in the fuel oil tank would be common. It is.

The propulsion device 6 includes a motor and an engine, and a screw propeller and a water jet propeller driven by the motor and engine. A motor or engine is operated by a power source such as electricity or fuel oil supplied from the power source supply device 5 and a propeller is generated by driving a screw propeller, a water jet propulsion device or the like by the generated power, and a trolling drone 1 sails.
The navigation, course change, and stop of the trolling drone 1 are performed by driving the propulsion device 6 while appropriately controlling the storage device 7 and the transmission / reception device 8 that will be described later. It will be.

In addition, there is an example in which two propulsion devices 6 are installed in parallel so as to protrude to the left and right of the body 4 as shown in FIG. It will be installed. For example, in the state as shown in FIG. 1, there is no problem even if another propulsion device 6 is provided at the lower part and a total of three machines are combined. In addition, the body 4 and the propulsion device 6 are integrated so as to reduce the resistance of water at the time of navigation, without the shape protruding from the body 4 as shown in FIG. It is good also as a shape.
In addition, about a rudder, it does not necessarily need to provide this, The specification which controls a some propulsion apparatus 6 and changes a course may be used, and providing the ballast tank for adjusting the depth of navigation is also considered. It is done.
In addition, a motor (or engine) and a screw propeller (or water jet propulsion device) may be combined on a one-to-one basis, and a plurality of screw propellers (or water jet propulsion devices) are driven by a single motor (or engine). It is good as a thing.
The power source supply device 5 and the propulsion device 6 are not a choice between a battery, a fuel oil tank, a motor and an engine, but a motor and an engine that are widely used in automobiles. A hybrid system is also conceivable.

  The storage device 7 is a device that bears a part of the brain of the trolling drone 1 in order to efficiently navigate the trolling drone 1 along a route with a high catch probability. The navigation route can be set for the storage device 7 by operating from a personal computer or the like connected wirelessly or by wire. For example, the navigation route is stored in a storage medium such as a USB memory, CD, or DVD, and stored. It is also possible to adopt a specification that is inserted into the device 7 and read. The route setting may be set as needed on board, taking into account weather conditions, sea conditions, and the location of the school of fish, etc., and a standard navigation route is determined in advance and this is input in advance from a personal computer etc. It is also assumed that the medium in which the navigation route is stored is replaced by a cartridge exchange method.

The position information signal receiving / transmitting device 8 receives the position information signal to specify the position of the own aircraft on the navigation route in order to cause the trolling drone 1 to autonomously navigate according to the navigation route stored in the storage device 7. To do. Although this receiving / transmitting device 8 that receives a position information signal has an antenna unit 9, a part of the upper surface of the body 4 is used to reliably receive the position information signal while the trolling drone 1 is submerged in water. In order to avoid the influence of waves during stormy weather, etc., the antenna unit 9 of the transmission / reception device 8 is transmitted / received. It is formed in the shape of a buoyant body (buoy) that can be separated from the main body of the device, connected to the main body of the receiving / transmitting device with an antenna cord extending from the upper surface of the body 4, and this buoyant-shaped antenna portion 9 is constantly levitated above the water surface. Alternatively, a position information signal may be received while pulling. In this case, in order to prevent disconnection, the antenna cord is devised such as covering the outer surface with a material such as corrosion resistant or strong rubber.
As a result, the trolling drone 1 measures the position of the own aircraft based on the received position information signal, and moves so as to follow the navigation route that is preset and stored in the storage device 7.
Further, the receiving / transmitting device 8 transmits a position information signal indicating its own position to the outside as necessary, and informs the fishermen who are monitoring the movement of the trolling drone 1 from a mother boat or the like. Also bears.

  Next, another brain part of the trolling drone 1 along with the storage device 7 is a control device 10. This is based on the position information signal received by the transmission / reception device 8 to determine the position of the own device, and by controlling the motor or engine of the propulsion device 6 or when a rudder or ballast tank is installed, The trolling drone 1 is controlled so as to autonomously follow the navigation route stored in the storage device 7. Like a computer system, this is a combination of hardware and software, and it can always evolve with software updates.

  As described above, the various devices (power source supply device 5, storage device 7, receiving / transmitting device 8, control device 10) incorporated in the body 4 of the main body 2 of the trolling drone 1 and the propulsion device 6 cooperate. Thus, the trolling drone 1 can autonomously travel on a route with a high fishing probability set in consideration of the movement route of the fish and the position of the flock.

And the tail part 3 which consists of the following various apparatuses fulfill | performs the function for moving according to the autonomous navigation of the main-body part 2 of the trolling drone 1 and to catch a fish reliably, pulling the fishing line 12 with the fishhook. Is.
Hereinafter, various devices constituting the tail portion 3 will be described.

The traction device 11 is connected to the body 4 of the main body 2.
The shape is a hollow, elongated cylindrical shape, and a fishing line 12 such as a wire or a teg is passed through the hollow part, and a fishing hook with bait or pseudo bait is tied to the fishing line 12 and pulled according to the self-contained navigation of the main body part 2. . The traction device 11 also functions to protect the fishing line 12 from being entangled with the trolling drone 1 due to the fish caught on the fishhook and the braking device 15 described later from being damaged by the fishing line 12. Depending on the type of fish, the pulling device 11 may be made of a metal or plastic having strength that does not break, but it is effective to use a lightweight and strong material such as CFRP (carbon fiber reinforced plastic). It is. In some cases, the material from the body 4 side to the distal end side of the braking device 15 is made of a material such as a metal that is hard and less bent, and the portion beyond the distal end portion of the braking device 15 beyond that is a flexible material. Further, while bending like a fishing rod, it may be devised to escape the power of the fish that is hung on the fishhook, and to more effectively suppress the rampage of the fishing line 12.

  The end of the fishing line 12 passed through the hollow traction device 11 (the side opposite to the side to which the fishhook is bound) is connected to the fish detection device 14 on the end side of the main body 2 of the traction device 11. In other words, this fish faith sensing device 14 is generally installed in the vicinity of the connection portion between the main body 2 and the tail portion 3 of the trolling drone 1. In this case, an installation space for the fish detection device 14 may be secured, for example, by slightly expanding the vicinity of the main body connection portion of the tail portion 3, and the fish detection device 14 may be stored in a part of the tail portion 3. The fish detection device 14 may be stored inside the body 4 of the unit 2. And this fish faith detection device 14 detects the attraction force exceeding the force set according to the fish type as a fish pull of the fishing line 12, and a braking device 15 for stopping the movement of the trolling drone 1 It will be activated via deployment of the device 16.

When it is detected by the fish detection device 14 that a fish has been applied, the braking device 15 is activated.
In fishing, a fisherman who senses a fish shin (operating) operates a fishing rod and acts as hooking to apply a reaction force that matches the movement of the fish so that the fishhook is securely hooked to the mouth of the fish. I do. This braking device 15 has the effect of reliably catching the fish hook of the catching means on the fish body, such as increasing the resistance of water so as to be a large reaction force against the pulling of the fish in conjunction with the rapid activation of the airbag device 16. Is generated.

The braking device 15 is folded so as not to obstruct the navigation when the trolling drone 1 is navigating. However, the operation of the airbag device 16 activated by the fish faith sensing device 14 causes the braking device 15 to be umbrella-shaped as shown in FIG. Will open.
FIG. 4 shows a simplified image of the operation of the airbag device 16.
The structure of the braking device 15 is a lightweight and strong umbrella skeleton 17 and receiving bone 19 made of a material such as CFRP (carbon fiber reinforced plastic), upper and lower rockers that bundle them, and an umbrella fabric that cannot be easily broken. 21. The umbrella fabric 21 is preferably a lightly tough material that does not absorb water and a sheet of plastic fiber that is neatly folded. Moreover, what corresponds to the middle stick of the umbrella is the tubular traction device 11 described above, and the lower rocker 20 connected so as to bundle the receiving bone 19 is connected to the main bone 17 on the body 4 side along the traction device 11. The brake device 15 is opened in an umbrella shape by moving toward the upper rocker 18 connected so as to be bundled together.

In order to open the braking device 15 in an umbrella shape, the airbag device 16 that is activated by the fish shin sensing device 14 performs the following operation.
First, gas is sent from the inflator (gas generating device) of the airbag device 16 into the airbag, and the airbag is deployed. Although this inflator and other ancillary equipment are not shown in FIG. 4, the storage position of the inflator may be the tail portion 3 that secures the installation space, as in the fish detection device 14, or the main body portion 2. It may be stored in the body 4.
And about the installation position of an airbag, it folds small and is installed so that the pulling device 11 may be enclosed in the back side of the receiving bone 19 and the lower rocker 20. The shape of the airbag is such that the airbag 4 is inflated so as to be drawn toward the body 4 side, and during operation, the lower roll 20 that binds the ribs 19 is attached to the main body while the airbag is inflated as shown in FIG. The braking device 15 opens in an umbrella shape by being pulled and moved to the upper side 18 that bundles the main bone 17 on the part 2 side.
Further, in the example of FIG. 4 (lower figure), the airbag is installed in a small folded manner so as to surround the traction device 11 between the upper and lower lofts 18, 20. By pushing open, the lower rocker 20 is drawn toward the upper rocker 18 side, and the braking device 15 is opened in an umbrella shape.

  It is also conceivable that a timer 23 for delaying activation of the airbag device 16 is installed between the fish faith detection device 14 and the airbag device 16 as shown in FIG. This is because it is considered that the timing of hooking (matching) varies depending on the type of fish to be captured, so that the braking device 15 is operated suddenly with a time difference from the fish pulling together with the bait or the pseudo bait. By hooking the swallowed fishhook over the mouth of the fish more reliably, the fishhook is removed from the fish and the effect of reducing the probability that the caught fish will be lost is brought about. With regard to the delayed activation time, if the specification can be appropriately changed, the braking device 15 corresponding to various fish species can be provided.

When the airbag device 16 is activated, the information is transmitted to the notification device 22 and the control device 10 of the main body 2.
The reporting device 22 reports to a fisherman waiting on a fishing boat that a fish has been caught on the trolling drone 1. At the same time, the control device 10 that has received information that the airbag device 16 has been activated stops the propulsion device 6 and stops the autonomous navigation of the trolling drone 1.

  As described above, the tail portion 3 performs trolling by hitting a fishhook while following the self-contained navigation of the main body portion 2. When the fish catches the fishhook, a large resistance force is generated by the action of the braking device 15, a reaction force against the fish pulling is generated, and a hooking operation (matching) for automatically increasing the catch of the fish is automatically performed. Then, since the fisherman is notified that this series of operations has been performed, the fisherman operates the fishing boat, etc., and based on the positional information signal transmitted from the trolling drone 1, The trolling drone 1 will be collected.

Next, a supplementary explanation of the fishing method using the trolling drone 1 will be given.
The size of the trolling drone 1 varies depending on the fish species to be captured. In the case of a large fish species such as black sea bream, it is appropriate that the total length from the main body to the tail portion is 2 m or more.
A route for navigating the trolling drone 1 is set in advance in consideration of the habitat area and migratory route of the fish to be captured, or the location of the fish school by the fish detector, and the navigation route is stored in the storage device 7. .
And the fisherman who headed for the capture area by the fishing boat etc. which loaded the trolling drone 1 surfaced the trolling drone 1 on the sea surface, and made it navigate independently according to the set navigation route.
At this time, the navigation depth of the trolling drone 1 is also set in consideration of the state of waves. Since it is necessary to appropriately receive and transmit the position information signal, in many cases, it is considered that the navigation is performed near the water surface within 3 m below the water surface.

The trolling drone 1 navigates to a fish habitat area, a migratory route, and a confirmed school of fish while pulling a fishhook 13 with a prey or a pseudo food as shown in FIG. The recognized fish will swallow it. However, the fishing line 12 of FIG. 5 is described briefly for the sake of simplicity.
When detecting the force applied to the fishing line 12, the fish faith detecting device 14 activates the airbag device 16 when detecting a fish pull larger than the set force.
In the normal state, the airbag is thinly folded between the traction device 11 and the braking device 15 as shown in FIG.

When a fish shin (perception) is detected, air is sent from the inflator of the airbag device 16 to the airbag, and the airbag is deployed to open the braking device 15 like an umbrella as shown in FIGS. .
The rods and the like hung on the fishhook 13 try to dive deeply into the water to escape, but the impact of the air bag device 16 that operates suddenly, the resistance of the brake device 15 that opens like an umbrella, and the gas are inflated. The fishhook 13 that has received a large reaction force against the movement of the rod or the like due to the buoyancy of the airbag will deeply bite into the mouth of the rod or the like.
Since the trolling drone 1 is sufficiently large and its resistance and buoyancy are also large, the kites cannot easily escape and eventually the power is exhausted.

Since the trolling drone 1 also has a function of notifying the starter of the airbag device 16 to a fisherman waiting on a fishing boat or the like and transmitting a position information signal of the own aircraft, In order to quickly collect the hung prey, we will head for the location information signal transmission place.
Taking into account the timing of hooking according to the fish species, the timer 23 delays the time from the detection of the fish signal (periphery) by the fish signal sensor 14 to the activation of the braking device 15, so that the fishhook As described in the description of the apparatus, the fishing probability is increased by hooking 13 deeply and reliably on fish.
Moreover, although it is the trolling drone 1 after having used once, it can be reused by making the airbag device 16 exchangeable, folding the brake device 15 opened in an umbrella shape, and re-installing it. Be possible.
