Description

【0001】
【発明の属する技術分野】
この発明は、定置網を用いて漁をする定置漁船の揚網機の装着構造に関するものである。
【0002】
【従来の技術】
定置漁業は海中に定置網を設置し、回遊してくる魚を網内に導いて捕獲するというもので、網は比較的沿岸に近い海域に設置される。定置網は海面に張られたワイヤや化繊ロープに懸吊された状態で設置されており、毎日漁船を網内に入れ、網の奥の部分を入口側から順に海面に寄せて魚を網の奥端に追い込んで水揚げする。
【0003】
従来はこの網起しや魚の捕獲を数隻の漁船で行なっていたが、漁価の低減と人件費の高騰、漁業人口の高齢化等のために、省力化と機械化が進み、1隻の漁船で水揚げや網の交換を行なうようになってきている。そのため、定置漁船は大型化し、搭載される省力化機械の増大して、トン数も大きくなっている。
【0004】
また漁業資源の減少や漁船の大型化に伴って、波の高い外海や従来より沿岸から離れた海域に網が設置されることも多くなり、以前であれば操業できなかった気象状況でも操業するようになってきている。
【0005】
定置漁船は、漁をするときは船を横向きにして移動させながら魚を追い込んでゆくこと、漁をするには網を懸吊しているワイヤや化繊ロープを乗り越えて網の内側に入らなければならないことなどのために、船幅が広く吃水の浅い平底の船が用いられている。
【0006】
定置網の網に関しては、漁獲量の増大や網の交換期間の延長、海中における網の安定性の増大などを目的として種々の改良がなされているが、定置漁船の改良はあまり行われていない。前述したように、漁船が大型化し、搭載される機械器具の重量が増し、波の高い海域をより遠くまで航行することが多くなっているが、従来の船型をそのままスケールアップして大型化に対応しているのが現状である。
【0007】
他方、外洋を航行する比較的大型の貨物船・商船・沖合漁業船等に採用される船首形状として、船首の吃水下に前方に突出する球状突起を設けた形状(球状船首、バルバスバウなどと呼ばれている)が採用されている。この船首形状は、航行時に船首が水をかき分けるときに生ずる波と水中を進行する球状突起によって生ずる波とが互いに打消し合って、造波抵抗が減少する作用が特に大型船の場合に大きいという特徴があり、更に船首に設けた突起が水中で上下動するときに水の抵抗を受けるために船のピッチングが抑えられること、突起を設けた分だけ船首部分の浮力が大きくなること、突起の長さ分だけ船の幅に対する長さが長くなるので航行抵抗が小さくなる等の特徴を持っている。
【0008】
【発明が解決しようとする課題】
定置漁船は上述した形状を備えているため、航行時に波によって船首が持ち上げられやすく、ピッチング、特に船が波に向って航行するときのピッチングが大きい。また近時の定置漁船は、船形が大型化しているため、波が高いときには船首が高く持ち上げられたあと海面に叩き付けられて大きな衝撃が生ずる。更に機械化された定置漁船の船首には、重い(通常3トン程度ある)揚網機が搭載されるため、ピッチングを起こしたときの衝撃が更に増大する。このような船の挙動は、搭乗者に不快感を与え、船の速やかな航行を妨げるばかりでなく、航行の安全を害する。
【0009】
この発明は、船首に揚網機を搭載した定置漁船の航行時のピッチングによる衝撃を抑えて、波のある海域での航行安全性に優れた定置漁船を提供することを課題としている。
【0010】
【課題を解決するための手段】
この発明の定置漁船は、船首に揚網機1を搭載した定置漁船において、上記揚網機の基台12が船首甲板に固定した前後方向のレール7に沿って摺動自在に装着されかつ当該レールと平行に配置されて揚網機1を船首側と船尾側に移動する駆動杆16に連結されていることを特徴とするものである。
【0011】
駆動杆16は、油圧シリンダのロッドとすることもできるが、好ましくは油圧モータ17駆動のねじ杆とし、このねじ杆を揚網機の基台12に固定したナット部材18と螺合して上記駆動杆16と揚網機の基台12とを連結する。
【0012】
この発明の定置漁船においては、揚網時には揚網機を船首側へ移動して操業を行い、航行時には揚網機をレール7の船尾側に移動して航行する。航行時に揚網機を船尾側に移動すると、波によって船がピッチングしたときの船の揺動中心から揚網機1までのモーメント長さが短くなり、従って船首が持ち上げられたり波に叩きつけられたりするときの衝撃が小さくなる。操業時には揚網機1を船首側に移動するので、揚網作業に支障が生ずることはない。駆動杆16としてねじ杆を用いれば、ねじのセルフロック作用により揚網機1がみだりに移動することを防止でき、ねじ杆16を油圧モータ17で駆動することで、海水による漏電や電気腐食の危険を回避できる。なお、揚網機の基台12のレール7に対向する箇所に固定ピンや固定バイスを設ければ、船首側及び船尾側の移動端で揚網機1を固定可能にできる。
【0013】
更に上記構造で揚網機を搭載した定置漁船において、船首底部から前方に突出する球状突起2を設け、この球状突起2の先端と船首上部3との間に上記球状突起2より幅狭い、例えばパイプや棒材等の杆材やリブなどの板材等からなる、網抑え部材4を設けて、この網抑え部材4により、船首上部3と球状突起2の先端との間に海面に設置された網やワイヤを球状突起2の下方へ案内する下向き後方に傾斜した網抑え縁6を形成することで、航行時のピッチングの発生を更に抑制できる。
【0014】
すなわち、船首底部に球状突起2を設けることにより、船首が波に突っ込み又波から離れるときの船首の上下動に抵抗を与えて、航行時における船のピッチングを抑制すると共に、船首に搭載される揚網機の重量に対応する浮力を船首部分に与え、かつ網抑え部材4によって形成された網抑え縁6により、船が漁場に入るときの船首への網やワイヤの引っ掛かりを防止できる。球状突起2の形状としては、比較的偏平で、上動しようとするときの水の抵抗の大きな形状とするのがより好適である。
【0015】
このパイプステイやリブのような網抑え部材4の下端を球状突起2に固定する固定手段として、ボルトによる締結構造などを採用したときは、その締結部分に形成される凹凸に網が引っ掛かるのを防止するため、網抑え部材4と球状突起2との接続部にファイバ補強樹脂などによる整形部を設けて、網抑え縁6の下端が滑らかに球状突起2の先端に連接されるようにする。
【0016】
【発明の実施の形態】
図2はこの発明の定置漁船の一実施例を示す全体側面図、図1はその船首部分の拡大側面図である。
【0017】
定置漁船は吃水の浅い平底の船型をしており、船尾のスクリュー及びラダー部分には、網やワイヤが引っかからないようにガードが設けられている。平面図は省略しているが、比較的船幅の広い矩形に近い平面形状の甲板を備えており、操舵室や機関室は後部に設けられて、船の中央から船首にかけて、水揚げした魚や網交換時に網を搭載するための広い甲板が設けられている。船首には揚網機1が搭載されている。
【0018】
この揚網機1は、定置漁船の船首甲板上に設けた前後方向のレール7上に移動自在に搭載されている。レール7は、平行に配置した2本のH形鋼からなり、船首甲板上に固定されている。揚網機1は、左右のガイド側板8の間に配置されたV形の周溝を有する揚網ローラ9と、その船尾側に位置する押えローラ10とを備えており、揚網ローラ9を回転駆動する油圧モータ11が設けられている。揚網機のこれらの機器を支持する基台12の底部に、レール7の上フランジを外側から抱くようにL形のスライドガイド13が左右前後2箇所ずつ設けられ、各レールの内側の位置には、押えガイド14が設けられている。基台12の底部のレール7の上面に接触する部分には、摩擦係数の小さな材料で製作されたスライドシュー15が添設されている。
【0019】
2本のレール7、7の中央には、前後端を軸受で甲板に軸支したねじ杆16がレール7、7と平行に装架され、その船尾側端部に油圧モータ17が連結されている。ねじ杆16は、揚網機の基台12の底部中央に固設したナット部材18に螺合している。油圧モータ17を正逆回転することにより、揚網機1はレール7の船首側端部と船尾側端部の間を移動する。操業時には揚網機1をレール7の船首側端部に移動して揚網作業を行い、航行時には船尾側端部に移動して航行する。揚網機が載っていない部分のレール7上には、適宜なカバーを設けてレール上面及びねじ杆を保護する。このカバーは、揚網機が船首側に移動したときと、船尾側に移動したときとで、当該揚網機の前後に移動させることにより、同一のものを操業時と航行時とに兼用できる。
【0020】
図示実施例の定置漁船には、船首底部に球状突起2が設けられている。図示実施例の球状突起2は、水中での上下方向の水の抵抗を大きくするために、前方から見たときに横に細長い偏平形状となっており、かつ上面が若干くびれた形状にして、特に水中で上動するときの水の抵抗を大きくするように考慮されている。
【0021】
球状突起2は、造波抵抗の減少作用をあまり期待しないので、必ずしも常時水面下にある必要はない。船首が波にぶつかったときには、船体が波に当たるより先に球状突起2が波の中に進入するので、ピッチングを低減する作用は十分に発揮できる。
【0022】
この球状突起2の先端上部と船首上部の球状突起の先端より前方の部分3との間に、ステンレスパイプ製のステイ4が装架されている。このパイプステイ4は、上端と下端とに設けたフランジを船首上部の下面及び球状突起2の先端上部にボルトで締結することによって固定されている。そして、その締結部には、グラスファイバー樹脂を積層した整形部を設けて、凹凸のない滑らかな形状としてある。
【0023】
パイプステイ4の前縁によって網やワイヤを下方へ案内する網抑え縁6が形成される。船が網内へ進入するとき、網、特に海面上に張られたワイヤや化繊ロープがパイプステイの前縁に衝突して、当該前縁の傾斜により、球状突起2の下方にワイヤや化繊ロープが案内されて、当該ワイヤや化繊ロープが船首に引っかかるのが防止され、船を網内の漁場へ乗り入れることができる。
【0024】
【発明の効果】
上述したこの発明により、重い揚網機を船首に搭載した定置漁船において、航行時に揚網機を船尾側に移動させることにより、船のピッチングを抑え、またピッチングをしたときの船首底部に作用する衝撃を抑えて、波のある海上を航行するときの定置漁船の航行安全性を高めることができる。この効果は、船首底部に球状突起を設けてない定置漁船においても、この発明を採用することにより得られる。
【0025】
更に実施態様に示すように、船首底部に球状突起を設けることにより、航行抵抗や航行時のピッチングを更に抑制した定置漁船を提供することができ、漁場に入るときに、海面に張られたワイヤや化繊ロープが船首の球状突起に引っ掛かる危険も防止できるので、定置漁船の大型化及び機械化並びに定置網の設置場所の拡大に伴って生ずる航行安全性や航行距離の増大に対応可能な定置漁船を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a lifting net of a stationary fishing boat that uses a stationary net for fishing.
[0002]
[Prior art]
In the fixed fishery, a fixed net is installed in the sea, and the migrating fish is guided into the net and caught. The net is set in the sea area relatively close to the coast. The stationary net is installed in a state of being suspended by wires or synthetic ropes stretched over the sea surface. The fishing boat is put into the net every day, and the back part of the net is brought into the sea surface in order from the entrance side to bring the fish into the back. Drive to the end and land.
[0003]
In the past, this reticulation and fish capture were carried out by several fishing boats. However, labor saving and mechanization have progressed due to a decrease in fishing prices, rising labor costs, and an aging fishing population. Fishing boats have been used for landing and changing nets. For this reason, stationary fishing boats have become larger, and labor-saving machines to be mounted have increased, resulting in a large tonnage.
[0004]
In addition, with the decrease in fishery resources and the increase in size of fishing boats, nets are often installed in waved open seas and areas far from the coast, making it possible to operate in weather conditions that could not be operated before. It has become like this.
[0005]
When fishing, a stationary fishing boat must drive the fish while moving the boat sideways. In order to fish, the fisherman must go over the wire and synthetic fiber rope that suspends the net and enter the inside of the net. For reasons such as not becoming necessary, flat-bottomed boats with a wide width and shallow water are used.
[0006]
Various improvements have been made to stationary nets for the purpose of increasing catch, extending the exchange period of nets, and increasing the stability of nets in the sea. However, fixed fishing vessels have not been improved much. As mentioned earlier, fishing boats have become larger, the weight of machinery and equipment mounted on them has increased, and it has become more frequent to travel farther in high-wave sea areas. The current situation is to support this.
[0007]
On the other hand, as a bow shape adopted for relatively large cargo ships, merchant ships, offshore fishing boats, etc. sailing in the open ocean, a shape with a spherical protrusion protruding forward under the bow of the bow (referred to as a spherical bow, Barbus bow, etc.) Is adopted). This bow shape is said to be particularly effective in the case of large ships because the waves generated when the bow splits the water during navigation and the waves generated by the spherical projections traveling in the water cancel each other. There is a feature, and the pitching of the ship is suppressed to receive the resistance of water when the projection provided on the bow moves up and down in the water, the buoyancy of the bow part increases by the provision of the projection, It has the characteristics that the navigation resistance is reduced because the length with respect to the width of the ship is increased by the length.
[0008]
[Problems to be solved by the invention]
Since the stationary fishing boat has the above-described shape, the bow is easily lifted by waves during navigation, and pitching, particularly when the boat sails toward the waves, is large. In addition, recent stationary fishing boats have a large shape, so when the waves are high, the bow is lifted high and then struck against the sea surface, causing a large impact. Further, since the head of a mechanized stationary fishing boat is equipped with a heavy (usually about 3 tons) lifting machine, the impact when pitching occurs further increases. Such behavior of the ship not only makes passengers uncomfortable and disturbs the ship's rapid navigation, but also compromises the safety of navigation.
[0009]
An object of the present invention is to provide a stationary fishing boat excellent in navigation safety in a waved sea area by suppressing impact due to pitching during navigation of a stationary fishing boat having a lifting net machine mounted on the bow.
[0010]
[Means for Solving the Problems]
Stationary vessels of the present invention, in the stationary vessels equipped with Agemo machine 1 at the bow, the base 12 of the lifting network machine, slidably mounted along a longitudinal direction of the rails 7 fixed to the bow deck is characterized in that either one is the rail and arranged in parallel with the lifting network device 1 is connected to a drive rod 16 to move fore and aft.
[0011]
The drive rod 16 may be a rod of a hydraulic cylinder, but is preferably a screw rod driven by the hydraulic motor 17, and the screw rod is screwed with a nut member 18 fixed to the base 12 of the lifting netting machine. The driving rod 16 and the base 12 of the lifting net are connected.
[0012]
In the stationary fishing boat according to the present invention, the lifting net is moved to the bow side during the lifting operation, and the lifting net is moved to the stern side of the rail 7 during the navigation. When the lifting net is moved to the stern side during navigation, the moment length from the center of rocking of the ship to the lifting net 1 when the ship is pitched by the wave is shortened, so the bow is lifted or struck by the wave. The impact when doing is reduced. During operation, the lifting machine 1 is moved to the bow side, so that there is no problem with the lifting work. If a screw rod is used as the drive rod 16, the lifting net 1 can be prevented from moving unnecessarily due to the self-locking action of the screw, and the screw rod 16 is driven by the hydraulic motor 17, thereby causing a risk of electric leakage due to seawater and electric corrosion. Can be avoided. In addition, if a fixing pin and a fixing vise are provided in the location facing the rail 7 of the base 12 of the lifting net, the lifting net 1 can be fixed at the moving ends on the bow side and the stern side.
[0013]
Further, in a stationary fishing boat having the above structure and equipped with a lifting net, a spherical protrusion 2 protruding forward from the bottom of the bow is provided, and is narrower than the spherical protrusion 2 between the tip of the spherical protrusion 2 and the upper portion 3 of the bow, A net restraining member 4 made of a plate material such as a rib or a rib, such as a pipe or a bar, is provided, and this net restraining member 4 is installed on the sea surface between the bow upper part 3 and the tip of the spherical protrusion 2 . the net or wire by forming a network suppressing edge 6 is inclined downward rearward to guide downward in the spherical protrusion 2, it can be further suppressed pitching generation during sailing.
[0014]
That is, by providing the spherical projection 2 at the bottom of the bow, it resists the vertical movement of the bow when the bow rushes into and away from the wave, suppresses the pitching of the ship during navigation, and is mounted on the bow. The buoyancy corresponding to the weight of the lifting netting machine is given to the bow portion, and the net restraining edge 6 formed by the net restraining member 4 can prevent the net or wire from being caught on the bow when the ship enters the fishing ground. As the shape of the spherical protrusion 2, it is more preferable to use a shape that is relatively flat and has high water resistance when attempting to move upward.
[0015]
When a fastening structure such as a bolt is used as a fixing means for fixing the lower end of the mesh restraining member 4 such as a pipe stay or rib to the spherical protrusion 2, the mesh is caught by the irregularities formed in the fastening portion. In order to prevent this, a shaping portion made of fiber reinforced resin or the like is provided at the connection portion between the mesh restraining member 4 and the spherical projection 2 so that the lower end of the mesh restraining edge 6 is smoothly connected to the tip of the spherical projection 2.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 2 is an overall side view showing an embodiment of a stationary fishing boat according to the present invention, and FIG. 1 is an enlarged side view of the bow portion.
[0017]
Stationary fishing boats have a flat bottom with shallow water, and guards are provided on the stern screw and rudder so that nets and wires are not caught. Although the plan view is omitted, it is equipped with a flat deck with a relatively wide rectangular shape, and the wheelhouse and engine room are located at the rear, and fish and nets are caught from the center of the ship to the bow. A wide deck is provided to mount the net during replacement. A lifting net 1 is mounted on the bow.
[0018]
The lifting net 1 is movably mounted on a front-rear rail 7 provided on the bow deck of a stationary fishing boat. The rail 7 is made of two H-sections arranged in parallel, and is fixed on the bow deck. The lifting net machine 1 includes a lifting net roller 9 having a V-shaped circumferential groove disposed between the left and right guide side plates 8 and a presser roller 10 positioned on the stern side thereof. A hydraulic motor 11 that rotates is provided. Two L-shaped slide guides 13 are provided on the bottom of the base 12 that supports these devices of the lifting net so as to hold the upper flange of the rail 7 from the outside in the left and right front and rear positions at the inside of each rail. The presser guide 14 is provided. A slide shoe 15 made of a material having a small friction coefficient is attached to a portion of the bottom of the base 12 that contacts the upper surface of the rail 7.
[0019]
At the center of the two rails 7 and 7, a screw rod 16 whose front and rear ends are supported by a deck with bearings is mounted in parallel with the rails 7 and 7, and a hydraulic motor 17 is connected to the stern side end. Yes. The screw rod 16 is screwed into a nut member 18 fixed at the center of the bottom of the base 12 of the lifting net. By rotating the hydraulic motor 17 forward and backward, the lifting net 1 moves between the bow end and the stern end of the rail 7. During operation, the lifting net 1 is moved to the bow end of the rail 7 to perform the lifting net operation, and during navigation, the lifting net 1 is moved to the stern end. An appropriate cover is provided on the rail 7 where the lifting machine is not mounted to protect the rail upper surface and the screw rod. This cover can be used both during operation and during navigation by moving the cover forward and backward when the lifting machine moves to the bow side and when it moves to the stern side. .
[0020]
In the stationary fishing boat of the illustrated embodiment, a spherical protrusion 2 is provided at the bow bottom. In order to increase the resistance of water in the vertical direction in water, the spherical protrusion 2 in the illustrated embodiment has a flat shape that is elongated horizontally when viewed from the front, and has a slightly constricted upper surface. In particular, it is considered to increase the resistance of water when moving up in water.
[0021]
The spherical protrusion 2 is not necessarily expected to be under the water surface at all times because it is not expected to reduce the wave resistance. When the bow hits the wave, the spherical protrusion 2 enters the wave before the hull hits the wave, so that the effect of reducing the pitching can be sufficiently exerted.
[0022]
A stay 4 made of stainless steel pipe is mounted between the upper end of the spherical protrusion 2 and a portion 3 ahead of the front end of the spherical protrusion at the upper bow. The pipe stay 4 is fixed by fastening flanges provided at the upper end and the lower end to the lower surface of the upper bow and the upper end of the spherical protrusion 2 with bolts. And in the fastening part, the shaping part which laminated | stacked glass fiber resin is provided, and it is set as the smooth shape without an unevenness | corrugation.
[0023]
A net restraining edge 6 for guiding the net or wire downward is formed by the front edge of the pipe stay 4. When a ship enters the net, a wire or a synthetic rope stretched on the net, particularly the sea surface, collides with the front edge of the pipe stay, and the wire or the synthetic rope is located below the spherical protrusion 2 due to the inclination of the front edge. Is guided to prevent the wire or the synthetic fiber rope from being caught on the bow, and the ship can enter the fishing ground in the net.
[0024]
【The invention's effect】
According to the present invention described above, in a stationary fishing boat having a heavy lifting machine mounted on the bow, it is possible to suppress the pitching of the ship by moving the lifting machine to the stern side during navigation and to act on the bottom of the bow when pitching. It is possible to suppress the impact and improve the navigation safety of the stationary fishing boat when navigating the waved sea. This effect can be obtained by adopting the present invention even in a stationary fishing boat in which a spherical projection is not provided at the bow bottom.
[0025]
Furthermore, as shown in the embodiment, by providing a spherical projection on the bottom of the bow, it is possible to provide a stationary fishing boat that further suppresses navigation resistance and pitching during navigation, and the wire stretched on the sea surface when entering the fishing ground Since it can prevent the risk of hooking the synthetic fiber ropes on the spherical projections on the bow, we will provide a stationary fishing boat that can respond to the increase in navigation safety and navigation distance that accompanies an increase in the size and mechanization of the stationary fishing boat and the expansion of the installation location of the stationary net can do.
