Description

The present invention relates to a control device for a fish collecting paddle capable of storing or deploying a paddle equipped with a fish collecting light equipped on a fishing boat.

As a fishing method for catching catch objects that have a habit of gathering in the light such as saury (phototaxis), after turning on multiple paddle fish collection lights at the same time and gathering the catch targets near the hull, each fish collection A method is known in which a group of fish to be caught is guided to a mechanism of a rod net and captured by controlling the light and sequentially changing the irradiation position. Conventionally, an omnidirectional halogen lamp, a metal halide lamp, or the like has been used as a light source for such a fish collecting lamp (see, for example, Patent Document 1), but nowadays, a light emitting diode (LED) having excellent luminous efficiency and directivity. Is often used.

In a general fishing boat used in the above fishing method, a paddle for attaching a fish-collecting lamp (which may be abbreviated as "fish-collecting paddle" or simply "paddle" in the present specification), which is also called an electric rod, has a hull. Multiple lines are deployed to enclose. Each paddle is held so as to extend upward at a predetermined inclination angle, and is supported so as to be swingable with its base end as a fulcrum. A long member called a tension rod or the like for holding the paddle at a predetermined inclination angle is attached to each paddle. In addition, multiple ropes are attached to each paddle, and by operating these ropes and deploying the paddle so that it protrudes from the hull, the fish collecting light attached to the tip side of each paddle is outboard. It is possible to irradiate light toward the sea surface around the hull.

When catching saury by the above fishing method using a fishing boat as described above, usually, each paddle is pulled toward the hull side and stored until it arrives at the offshore fishing ground, and when it arrives at the fishing ground, each paddle is stored from outside the ship. Arrange them in a substantially radial pattern so that they stick out, and approach the school of fish detected by using a fish finder or search light while turning on the fishing light to attract saury near the hull. Next, after turning off the fish-collecting lights on the port side and setting up a stick net on the port side while collecting saury on the starboard side, by controlling each fish-collecting light and sequentially changing the irradiation position, it migrates in a large group. Guide the saury to the stick net and capture it. The saury group guided into the rod net is sucked up with seawater by a fish pump and stored in the fish storehouse. This work is done several times at night, and when a certain amount of catch is obtained, when returning to the port after fishing, the deployed paddle is pulled inside the ship and stored by tying it with a rope etc. Don't get in the way. The fish-collecting paddle is also stored in the event of stormy weather. The extension and storage of this paddle is currently done manually by the crew.

One fish collecting light is installed from the tip side of each paddle, or three to four are installed at regular intervals. Regarding the weight of the paddles for collecting fish deployed on saury fishing boats, for example, 3 to 4 fish collecting lights (hereinafter referred to as "LED type fish collecting lights") that use light emitting diodes as light sources, which are widely used these days, are attached. Including the weight of the paddle, each one weighs about 80 kilograms. Some of the paddles deployed on saury fishing boats have a length of about 7.5 to 9 meters, and heavy fish-collecting lights are attached to these long paddles. Normally, about 20 paddles are deployed on a medium-sized saury fishing boat of about 100 tons, and about 37 paddles are deployed on a large saury fishing boat of nearly 200 tons at predetermined intervals. Conventionally, each paddle has been independently deployed so that the irradiation position and irradiation angle of each fish collecting lamp can be adjusted separately.

In order to manually move such a long and heavy paddle or hold it at a predetermined position or tilt angle, it is used for aerial work called a catwalk along the side (side of the ship). A yakura-shaped scaffold with a narrow passage may be constructed. The worker climbs up to the scaffolding, manipulates the rope connected to the paddle, moves the fish collecting light to the desired position, ties it to a structure such as the scaffolding, and ties it up to store or deploy the paddle. Do. When storing the paddle, it is usually arranged so that its tip faces the stern side.

Offshore off the sea is in an unstable and dangerous environment subject to high waves and strong winds, and the fishing method using a fish-collecting lamp is carried out at night after sunset. Conventionally, the storage or unfolding work of the paddle has been performed manually by climbing on the scaffolding provided on the side, which is dangerous and has a heavy physical burden. In addition, each paddle is deployed independently, and since the storage and deployment work was performed one by one, the work efficiency was poor, and it was necessary to devote a large number of personnel to the storage and deployment work of the paddle, and it was captured. There was a problem that personnel could not be assigned to other tasks such as. For example, it took about 3 minutes to store one paddle even if 3 to 4 people were assigned, and it took nearly 2 hours to store 37 paddles.

In order to ensure the freshness of the fish, it is necessary to return to the port immediately after storing it in the fish storehouse, but the conventional method has poor work efficiency and requires a lot of work time as described above. In addition, since offshore vessels are in an unstable environment that is prone to shaking, a highly stable configuration that is unlikely to cause a tipping accident as a device for maneuvering a heavy paddle with a fish collecting light attached.

FIG. 2 is a plan view showing an arrangement of a fish-collecting paddle to be deployed on a fishing boat to which the device can be applied and an example of a mounting area of the device, regardless of the embodiment of the fish-collecting paddle control device according to the present invention. Is. The control device for the fish collecting paddle according to the present invention motorizes (mechanizes) the deployment or storage work of the fish collecting paddle, and in any of the embodiments described later, a plurality of paddles for attaching the fish collecting light are deployed. It is assumed that it will be installed on the fishing boat 3, but in particular, a plurality of paddles deployed linearly at regular intervals, such as a plurality of paddles 2 deployed along the side S. It is a suitable technique applied to, for example, and is installed in the area 4 shown by the alternate long and short dash line in FIG.

The angle of inclination (elevation angle) of the fish collecting paddle 2 with its base end as a fulcrum is set to be about 45 ° upward with respect to the horizontal plane. In this regard, in the past, it was thought that better catch could be obtained by fine-tuning the inclination angle of the paddle at the time of deployment for each paddle. Therefore, each paddle was individually deployed and each paddle was deployed. The tilt angle was adjusted for each paddle by manipulating the tension rod connected to the paddle. However, according to the consideration based on the findings of the inventors, even if the inclination angle of the paddle is finely adjusted, it does not affect the catch so much, and even if the inclination angle of the paddle is uniformly maintained at, for example, about 45 °. Sufficient catch can be obtained. Therefore, the present invention proposes a control device 1 for a paddle for collecting fish, which can swing between a deployment position and a storage position while uniformly holding the inclination angle of each paddle at a constant angle. The angle of inclination of the paddle can be arbitrarily changed according to the type of the object to be caught, the length of the paddle, and the like.

As shown in FIG. 2, the fishing boat 3 is equipped with eight fishing paddles 2 on the bow side, 21 on the starboard side, and nine on the port side (one of which is a large paddle). Each paddle is deployed at a predetermined tilt angle (elevation angle). The length dimension of the fish collecting paddle 2 is about 7.5 to 9 meters, excluding the large paddle (parent paddle). A fish collecting lamp 5 (shown by a broken line in FIG. 1) is fixed to each of the fish collecting paddles 2 with the irradiation surface facing downward. The fish collecting light 5 is an LED type fish collecting light, in which a large number of red, green, or blue LEDs (Light Emitting Diodes) are arranged inside a box-shaped case to serve as a light source, and is supplied via a cable (not shown). By controlling the electric power, it can be turned on or off at an appropriate timing. The total number and length of paddles to be deployed on a fishing boat, the location of the paddles, and the type of fishing light are arbitrarily set according to the size of the boat and the target of fishing. By arranging the paddles at regular intervals, the lengths of the connecting members, which will be described later, can be made uniform.

FIG. 3 is a side view showing an example of the configuration of the paddle receiving metal fitting 6. In order to swing each fish collecting paddle 2 so as to be swingable, a paddle receiving metal fitting 6 generally used in the past is attached to the base end portion of each paddle 2. The paddle receiving metal fitting 6 is integrated with a tubular portion 8 attached to the base end portion of the support column 7 and opening vertically upward, a swivel shaft portion 9 rotatably inserted into the tubular portion 8, and the upper end of the swivel shaft portion 9. It is provided with a connecting piece portion 10 which is provided as a base and a hole is formed horizontally. The tubular portion 8 is fixed to a side view U-shaped spacer 11 welded to the support column 7. Fastening holes corresponding to the holes are provided at the base end of the paddle 2, and the base end of the paddle 2 is fastened by inserting a headed bolt 12 into each hole and fastening at a predetermined inclination angle. It is supported so that it can swing in the horizontal direction as a fulcrum. During the fishing holiday, the paddle and the fishing light are removed from the hull and stored in the warehouse. Therefore, the paddle 2 and the paddle receiving metal fitting 6 are detachably fastened with a nut screwed into the head bolt 12. There is.

For convenience of explanation, the drawing of the fish collecting lamp is omitted in each drawing, and preferably, the number of paddles connected to the connecting rod as the connecting member is three or more. According to the control device 1 for the fish collecting paddle having the above configuration, as shown in FIGS. 4 to 6, a plurality of adjacent paddles 2 are collectively and simultaneously moved by using a power source. Compared to the conventional method of manually operating the paddles one by one, there is no need to adjust the angle or position the paddles, and the danger and physical burden on the workers associated with the storage and deployment work of the paddle 2 is greatly reduced. It is possible to improve the work efficiency and reduce the work time required for storing or deploying the paddle 2. In addition, as will be described later, it is possible to provide a control device for a paddle for collecting fish with higher stability than a fishing boat of a type that retracts or deploys the paddle by rotating it in the vertical direction. In addition, by restricting the expansion and contraction of the rod, it is not necessary to tie the paddle with rope work, and it is not always necessary to install a scaffolded Yakura as described in the background technology. Hereinafter, each configuration and operation will be described in detail.

The stanchions 7 are erected at predetermined positions on the ship corresponding to the deployment interval of the fish collecting paddle 2. A paddle bracket 6 is attached to the base end of the support column 7. The horizontal member 13 is fixed at a predetermined height position of each support column 7 so as to be bridged over the columns 7 adjacent to each other. The horizontal member 13 is formed of a shaped steel having a square cross section, which includes a front surface serving as an arm receiving metal fitting mounting surface and a back surface serving as an electric actuator mounting surface. A fixed structure is formed by the support column 7 and the horizontal member 13.

The rod 14 is a member attached to a support column 7 or a horizontal member 13 and driven to reciprocate in the horizontal direction by a power source. When the rod 14 is reciprocated, the link mechanism 15 is driven by the rod 14 to reciprocate the rod 14. 2 swings in the horizontal direction. An electric actuator 32 is used as a device including the rod 14 and a power source, but a hydraulic, pneumatic, or internal combustion engine can also be used as the power source. The rod 14 is arranged so that its expansion and contraction direction is horizontal, and its tip is connected to the link mechanism 15 by a configuration described later.

The link mechanism 15 connects each of at least two or more rods 2 arranged adjacent to each other with the rod 14, and swings the rod 2 in the horizontal direction in accordance with the reciprocating motion of the rod 14. , The first shaft body 16, the connecting plate 17, the connecting rod 18 as a connecting member, one end side is swingably connected to the connecting rod 18 via the second shaft body 19, and the other end side is the third shaft body 20. It has an arm 21 that is swingably connected to a rod 14 via a rod 14, and an arm receiving metal fitting 24 that includes a tubular body 22 and a fourth shaft body 23. In order to connect the plurality of paddles 2 to the connecting rod 18, the link mechanism 15 has a plurality of connecting plates 17. Further, in order to enable swinging in the horizontal direction, each of the first shaft body 16, the second shaft body 19, the third shaft body 20, the fourth shaft body 23, and the fifth shaft body 33 described later is vertical. Arranged in the direction.

In the present embodiment, the clamp metal fitting 25 is fastened to the middle abdomen of the rod-shaped paddle 2, and the first shaft body 16 is projected vertically downward by welding to the clamp metal fitting 25 (see FIG. 7). For the paddles to which the same connecting rods are connected, each of the first shaft bodies 16 is projected at the same height position. When the connecting member is arranged between the paddle and the ship edge, the first axle body projects vertically upward with respect to the paddle 2.

FIG. 7 is a side view showing a connected state of the fish collecting paddle 2 and the connecting member 18. The connecting plate 17 is a rectangular member, and a first shaft body rotation hole is formed at one end thereof, and a connecting rod 18 is fixed to the other end by welding. The first shaft body 16 is formed by welding the head of a headed bolt, and when the nut 26 is attached to the headed bolt, the connecting plate 17 can swing with respect to the paddle 2. It is connected.

The connecting rod 18 is a member that is arranged substantially horizontally and is connected to the paddle 2 via the connecting plate 17 to connect the paddles 2 arranged adjacent to each other to each other. Although it is formed of a cylindrical steel pipe in the present embodiment, it may be formed of a shaped steel such as an L-shaped steel. Further, in the case shown in FIG. 1, two connecting rods 18 are used to connect the three paddles 2, but the number of members constituting the connecting member and the paddles connected to each connecting member are used. The number of is arbitrary. Further, a member which is stretchably connected by inserting a plurality of cylindrical members into each other, such as a telescopic fishing rod, may be used as the connecting member. By making the connecting member expandable and contractible, the connecting member can absorb the shaking of the hull and the distortion between the constituent members of the control device of the fish collecting rod.

In order to connect the arm 21 to the connecting rod 18, a connecting piece 27 having a second shaft body rotation hole is welded to one of the connecting rods 18 (the connecting member on the front side in FIG. 1). There is. The arm 21 is formed of a cylindrical steel pipe, and a hole penetrating vertically is formed on one end side thereof, and a head bolt is inserted into the hole and the second shaft body rotation hole. A biaxial body 19 is formed. It should be noted that the connecting rod 18 may be provided with a second shaft body rotating hole to be directly connected without providing the connecting piece 27.

On the other hand, a connecting metal fitting 28 provided with a third shaft body 20 is fitted at a predetermined position on the other end side of the arm 21, and the tip of the rod 14 is attached to the connecting metal fitting 28 to form a third. The rod 14 is swingably connected to the arm 21 via the shaft body 20 in the horizontal direction. The connecting metal fitting 28 includes a cylindrical clamp portion 29 having a tightening screw 29a and fitted into the arm 21, a cylindrical mounting portion 30 into which the tip of the rod 14 is inserted, and a clamp portion 29 and a mounting portion 30. It is provided with a third shaft body 20 for swingably connecting the above.

The arm receiving bracket is a component that supports the arm so as to be swingable in the horizontal direction. By providing the arm receiving bracket, each component of the link mechanism connected to the arm can be smoothly swung at sea with shaking. Can be made to. The arm receiving bracket includes a tubular body into which the middle abdomen of the arm is inserted and a fourth axial body that is rotatably attached to the horizontal member, so that the arm can be reciprocated with respect to the tubular body. It may be inserted, or the arm may be inserted into the cylinder so as not to reciprocate. FIG. 8 is a side view showing an example of the configuration of the arm receiving metal fitting 24 according to the former insertion form. In particular, the arm 21 is rotatably attached to the horizontal member 13 so that the middle abdomen of the arm 21 can reciprocate. It is a figure which shows the inserted arm receiving metal fitting 24 from the longitudinal direction of an arm. The fourth shaft body 23 is rotatably inserted into a tubular portion 31 that is fixed to the horizontal member 13 and opens vertically, and the tubular body 22 is attached to the upper end of the fourth shaft body 23. A U-shaped connecting portion 23a having a hole is provided at the upper end of the fourth shaft body 23, and a hole is formed at the bottom of the tubular body 22 and inserted into the U-shaped connecting portion. The connecting piece 22a is provided, and the tubular body 22 is attached to the upper end of the fourth shaft body 23 by fastening them with the fastening member 36. However, this is merely an example, and the tubular body is subjected to welding or the like. The fourth shaft body may be provided integrally.

On the other hand, in the latter insertion form, the length and connection position of each component of the link mechanism are adjusted so that the link mechanism can swing even when the arm is fixed to the tubular body, and then a fastener (not shown) is used. By fixing the arm inserted into the cylinder using the above, the arm cannot be reciprocated. According to this insertion form, the rigidity of the entire link mechanism is increased, and the external force (axial force, etc.) acting on the arm can be received by the fixed structure (horizontal member) via the tubular body, and the rod (electric actuator). ) Contributes to protection.

According to the control device 1 for the fish collecting paddle provided with the link mechanism 15, by expanding and contracting the rod 14 by the electric actuator 32, a swinging force is applied to each paddle 2 via the arm 21 and the connecting rod 18 connected to the rod 14. Each rod 2 swings in the horizontal direction with the base end as a fulcrum. By controlling the electric actuator 32, each paddle 2 can be moved all at once to a predetermined position including the unfolding or storing position, or can be stopped at the position, and the above-mentioned effect can be exhibited.

In the control device 1 for the fish collecting rod, preferably, the electric actuator 32 including the rod 14 and the power source is attached to the horizontal member 13 via the fifth shaft body 33. As a result, the link mechanism 15 can be operated smoothly, the swing range is expanded, and each paddle 2 is substantially parallel to the side wall surface of the hull from a position orthogonal to the side wall surface of the hull (see FIG. 4). It can be swung at a horizontal swing angle of 0 ° to 90 ° up to the position (see FIG. 6), which facilitates deployment and storage work. The fifth shaft body may be attached to the support column 7.

More preferably, the control device 1 for the fish collecting paddle has a horizontal length L from the first shaft body 16 to the outer surface of the connecting rod 18 larger than the radius r of the paddle 2 (see FIG. 6). That is, the connecting plate 17 is dimensioned in the longitudinal direction so that the horizontal length L from the first shaft body 16 to the connecting rod 18 is larger than the radius r of the paddle 2, and the other end is the connecting rod. It is fixed at a substantially right angle to 18. With this configuration, when the paddle 2 is stored, the paddle 2 and the connecting rod 18 do not interfere with each other, and as shown in FIG. 6, the paddle 2 and the connecting rod 18 are folded to a position where they are substantially parallel to each other. Can be crowded and stored.

In the present embodiment, a tension rod 34 is connected to each paddle 2. The tension rod 34 is formed of a round rod, one end of which is horizontally rotatably connected to the middle abdomen of the support column 7 by a metal fitting 35, and the other end of which is connected to the middle abdomen of the paddle 2 so that the ship shakes and vibrates. Even when it acts, it supports the heavy rod 2 to which the LED fish collecting lamp 5 is attached at a predetermined inclination angle. When the ship sways due to wave power in the deployed state of the paddle 2, a bending force acts on the paddle 2, but by connecting the tension rod 34, the bending of the paddle 2 can be suppressed, and the paddle 2 can be set to a predetermined value. The paddle 2 can be swung smoothly while being held at an inclination angle (elevation angle).

First, each rod 2 is pulled toward the hull side and stored by keeping the rod 14 extended to a predetermined position (see FIG. 6) until it arrives at the offshore fishing ground. Next, when arriving at the fishing ground, the rod 14 is retracted to a predetermined position (see FIG. 4), and each paddle 2 is radially expanded and arranged so as to protrude from the outboard, and then by the method described in the background technique. , Collect, guide and capture saury and store it in the fish storehouse. When returning to the port after fishing, the rod 14 is extended to a predetermined position (see FIG. 6), and the unfolded paddle 2 is pulled inside the ship and fixed with a rope or the like to store it, which hinders navigation. Try not to be. In this regard, in the past, the storage or deployment work of the paddle was performed by manually operating the rope by climbing on the scaffolding provided on the side, or it was dangerous and physically burdensome, and it was not stored. There was a problem that the work efficiency was poor because the deployment work was done one by one, but on the other hand, according to the control device 1 of the fish collecting rod, it is possible to store or deploy a plurality of rods 2 at the same time, which is dangerous. Moreover, it is possible to improve work efficiency by being freed from work that places a heavy physical burden. Since the paddle can be stored immediately after storage in the fish storehouse and returned to the port, the freshness of the fish can be maintained more than before.

By the way, since the fishing boat 3 is equipped with various devices and equipment, it may be difficult to install the first embodiment due to the space.
