Description
本願発明は、発電所等の取水口に進入するクラゲを処理するシステムに関し、特に、処理対象であるクラゲを水揚げすることなく洋上で処理するクラゲの洋上処理システムに関する。 The present invention relates to a system for processing a jellyfish that enters a water intake of a power plant or the like, and more particularly, to an offshore processing system for a jellyfish that processes a jellyfish that is a processing target on the ocean without landing.
火力発電所や原子力発電所等においては、冷却水として海水を使用するが、海水を取り入れる取水口には海水とともにクラゲ等の浮遊生物が取り込まれる。このため、クラゲが大量発生すると、取水された海水から塵芥を取り除く除塵機に過負荷がかかって故障の要因となるほか、取水量が低下して負荷が抑制され、電力の安定供給が阻害される場合が生じる。 In thermal power plants, nuclear power plants, and the like, seawater is used as cooling water, but floating organisms such as jellyfish are taken into the intake port for taking in seawater. For this reason, when a large amount of jellyfish is generated, the dust remover that removes the dust from the taken seawater is overloaded, causing a failure, and the amount of water intake is reduced, the load is suppressed, and stable power supply is hindered. May occur.
従来、発電所等の取水口に進入するクラゲを処理するために、除塵機の手前でクラゲを捕集し、捕集されたクラゲを水揚げして陸上の廃棄物処理容器で水抜きし、廃棄物として処理していたが、クラゲの処理に毎年多大なコストを要していた。
このため、捕集されたクラゲを廃棄物として処理せず、洋上で自然消滅させるクラゲの洋上処理システムが出願人によって開発された（特許文献１参照）。Conventionally, in order to treat jellyfish entering water intakes at power plants, etc., jellyfish are collected in front of the dust remover, the collected jellyfish are landed, drained in a land-based waste disposal container, and discarded. Although it was processed as a product, it was very expensive every year to process the jellyfish.
For this reason, the applicant has developed an offshore treatment system for jellyfish that does not treat the collected jellyfish as waste, but naturally disappears on the ocean (see Patent Document 1).
特許文献１に記載された従来のクラゲの洋上処理システムは、網状の部材で籠状に形成され、洋上においてクラゲを貯留するクラゲ貯留槽と、取水口付近のクラゲを吸引し、クラゲ貯留槽に生きたまま移送するクラゲ移送手段とを備え、収容されたクラゲを水揚げすることなくクラゲ貯留槽に貯留することで自然消滅させるものである。 The conventional jellyfish offshore processing system described in Patent Document 1 is formed in a bowl shape with a net-like member, sucks jellyfish in a jellyfish near the water intake, and stores the jellyfish near the water intake in the jellyfish storage tank. It is equipped with a jellyfish transporting means for transporting it alive, and naturally disappears by storing the stored jellyfish in a jellyfish storage tank without landing.
このようなクラゲの洋上処理システムを実用化することによって、捕集されたクラゲを水揚げして廃棄物として処理することが抑制され、クラゲを処理するためのコストが低減されるという効果が得られている。 By putting such a jellyfish offshore treatment system into practical use, it is possible to suppress the landing of the collected jellyfish as waste and to reduce the cost for treating the jellyfish. ing.
しかしながら、従来のクラゲの洋上処理システムでは、短期間に大量のクラゲがクラゲ貯留槽に流入した場合に、槽内のクラゲの密度が上昇し、クラゲが少ないときよりも早い速度でクラゲが消耗（クラゲが粘液を分泌して痩せること）し、より短期間で消滅する分、クラゲの消滅が原因で生ずる主にアンモニア、濁度、化学的酸素消費量（ＣＯＤ）の増加等の水質変化が大きくなり、水質基準の範囲内で実施する上で問題があった。 However, in the conventional jellyfish offshore treatment system, when a large amount of jellyfish flows into the jellyfish storage tank in a short period of time, the density of the jellyfish in the tank increases, and the jellyfish is consumed at a faster rate than when there are few jellyfish ( Jellyfish secretes mucus and disappears in a shorter period of time, and water quality changes such as ammonia, turbidity, and increase in chemical oxygen consumption (COD) are mainly caused by the disappearance of jellyfish. Therefore, there was a problem in implementing it within the range of water quality standards.
このため、クラゲ貯留槽内のクラゲの量が許容量を超えた場合には、クラゲ移送手段によるクラゲの移送先を陸上の廃棄物処理容器に切替えて、槽内の水質を基準内に抑えるようにすることを余儀なくされていたが、陸上の廃棄物処理容器に移送されたクラゲは、海水から分離されて水揚げされたものであるため、海洋汚染および海洋災害の防止に関する法律等に従って、結局は廃棄物として処理しなければならず、クラゲが大量に来襲した場合のクラゲ処理の費用を十分に削減できないという問題があった。
また、陸上の廃棄物処理容器に回収されたクラゲは水抜きして減容化を図る過程で、クラゲ特有の悪臭を発生し、ハエなどが集まって衛生的にも問題があった。For this reason, when the amount of jellyfish in the jellyfish storage tank exceeds the allowable amount, the jellyfish transfer destination by the jellyfish transfer means is switched to the land waste disposal container so that the water quality in the tank is kept within the standard. However, because the jellyfish transported to the land-based waste disposal container were separated from the seawater and landed, the jellyfish was eventually landed in accordance with the laws on the prevention of marine pollution and marine disasters. There is a problem that the cost of jellyfish treatment cannot be reduced sufficiently when it must be treated as waste and a large number of jellyfish attack.
In addition, the jellyfish collected in the land-based waste disposal container generated odors peculiar to jellyfish in the process of draining and reducing the volume, and flies gathered, causing problems in terms of hygiene.
また、クラゲ貯留槽に短期間に大量にクラゲが流入すると、貯留槽内で海水が滞留する部分や海面付近においてクラゲ同士が接触し、クラゲの体表粘液が剥がれるため、有機物濃度が増加し、海水の粘性が増すことによって、貯留槽内のクラゲ消滅時に特有の泡等が発生し、クラゲ貯留槽周辺の景観を著しく損なう等の環境への影響という問題があった。 In addition, when a large amount of jellyfish flows into the jellyfish storage tank in a short period of time, the jellyfish come into contact with each other in the part where the seawater stays in the storage tank or near the sea surface, and the body surface mucus of the jellyfish peels off, increasing the organic matter concentration, Due to the increase in the viscosity of the seawater, there are problems such as bubbles that are characteristic when jellyfish in the storage tank disappear, and the environment around the jellyfish storage tank is severely damaged.
それ故に、本願発明の目的は、クラゲが大量に来襲した場合においてもクラゲ貯留槽内の水質の変化を緩和し、収容されたクラゲを適切に自然消滅させることで、回収されたクラゲを水揚げして廃棄物として処理しなければならなくなるケースの発生を抑制し、クラゲの処理コストを更に低減するとともに、景観等の環境への影響を改善することができるクラゲの洋上処理システムを提供することである。 Therefore, the object of the present invention is to relieve the change in the water quality in the jellyfish storage tank even when a large number of jellyfish invade, and land the recovered jellyfish by properly erasing the contained jellyfish. By providing a jellyfish offshore treatment system that can reduce the cost of jellyfish treatment and further improve the impact on the environment such as landscape is there.
この発明にかかるクラゲの洋上処理システムは、網状の部材で籠状に形成され、洋上においてクラゲを海水中に貯留するクラゲ貯留槽と、取水口付近のクラゲを吸引し、生きたまま前記クラゲ貯留槽に移送するクラゲ移送手段とを備え、取水口付近に来襲したクラゲを水揚げすることなく前記クラゲ貯留槽に貯留して自然消滅させるクラゲの洋上処理システムにおいて、前記クラゲ貯留槽は、槽内の表層部に還流を生成させるために、側面の海面から深さ方向の一部を目張りする目張り手段を備えたものであって、前記目張り手段は、前記クラゲ貯留槽内のクラゲの減容速度を制御するために、深さ方向の目張りする範囲を調節する目張り範囲調節手段を備え、前記クラゲ貯留槽に流入するクラゲの量を検出するクラゲ流入量検出手段を備え、前記クラゲ流入量検出手段により検出されたクラゲの量によって、前記目張り範囲調節手段により前記クラゲ貯留槽の目張りする範囲を調節し、前記クラゲ貯留槽内のクラゲの減容速度を制御するようにしたものである。
この発明によれば、クラゲ貯留槽は、側面の海面から深さ方向の一部を目張りする目張り手段を備えるので、クラゲ移送手段によりクラゲとともに流入する海水によって表層部に穏やかな還流が生成され、これによって表層部において運動能力の高い元気なクラゲを一定期間活かした状態に保持し、その後運動能力の低下したクラゲが下層部に降りてきて下流側の網地に張り付いて消滅するというプロセスによってクラゲの減容を図ることができ、収容されたクラゲを水質の変化を緩和しつつ自然消滅させることができる。
また、この発明によれば、目張り手段は、深さ方向の目張りする範囲を調節する目張り範囲調節手段を備えるので、クラゲ貯留槽の表層部の還流が形成される範囲を調節することができ、クラゲが大量に来襲して表層部のクラゲの密度が高くなった場合においても、海面から深さ方向の目張りする範囲を増やすことで、還流が形成された表層部の容積が拡大され、表層部のクラゲの密度を下げることができるため、クラゲの減容速度が抑えられ、水質の変化を緩和することができる。
また、この発明によれば、クラゲ貯留槽に流入するクラゲの量を検出するクラゲ流入量検出手段を備え、クラゲ流入量検出手段により検出されたクラゲ流入量によって、目張り範囲調節手段によりクラゲ貯留槽の目張りする範囲を調節するようにしたので、クラゲの来襲量に応じて目張りする範囲を調節することでクラゲ貯留槽内のクラゲの減容速度を適切に制御することができ、クラゲ貯留槽に収容されたクラゲを水質基準を満たす範囲の最適な減容速度で自然消滅させることができる。これにより、クラゲ貯留槽が持つクラゲの処理能力を最大限に活かしたクラゲの洋上処理を行うことができる。また、回収されたクラゲをクラゲ貯留槽内の水質を基準内に抑えるために水揚げして廃棄物として処理しなければならなくなるケースの発生を抑制することができ、クラゲの処理コストを更に低減することができる。The offshore processing system for jellyfish according to the present invention is formed in a bowl shape with a net-like member, and sucks jellyfish in the vicinity of the water intake jellyfish in the sea and the jellyfish storage A jellyfish transporting means for transporting to a tank, and storing the jellyfish that invade near the water intake in the jellyfish storage tank without landing and killing it naturally, the jellyfish storage tank In order to generate reflux in the surface layer portion, it is provided with a weathering means for weathering a part of the depth direction from the sea surface on the side surface, and the weathering means has a volume reduction rate of the jellyfish in the jellyfish storage tank. In order to control, a range adjustment means for adjusting the range in the depth direction is provided, and a jellyfish inflow amount detection means for detecting the amount of jellyfish flowing into the jellyfish reservoir is provided. According to the amount of jellyfish detected by the jellyfish inflow amount detection means, the range of the jellyfish storage tank is adjusted by the weathering range adjustment means, and the volume reduction rate of the jellyfish in the jellyfish storage tank is controlled. Is.
According to this invention, since the jellyfish storage tank is equipped with a weathering means for weathering a part of the depth direction from the sea surface of the side surface, a gentle reflux is generated in the surface layer portion by the seawater flowing together with the jellyfish by the jellyfish transporting means, By this process, the jellyfish with high athletic ability in the surface layer is kept in a state where it has been utilized for a certain period of time, and then the jellyfish with reduced athletic ability descends to the lower layer and sticks to the downstream net and disappears. The volume of the jellyfish can be reduced, and the contained jellyfish can be naturally extinguished while mitigating changes in water quality.
In addition, according to the present invention, the weathering means includes the weathering range adjustment means for adjusting the range of the depth direction weathering, so that the range in which the reflux of the surface portion of the jellyfish storage tank is formed can be adjusted, Even when a large amount of jellyfish invade and the density of the jellyfish in the surface layer increases, the volume of the surface layer part where the reflux is formed is increased by increasing the range of the seam in the depth direction from the sea surface, and the surface layer part Since the density of jellyfish can be reduced, the volume reduction rate of jellyfish can be suppressed, and the change in water quality can be mitigated.
Further, according to the present invention, the jellyfish inflow amount detecting means for detecting the amount of the jellyfish flowing into the jellyfish storage tank is provided, and the jellyfish storage tank is adjusted by the eyelid range adjusting means according to the jellyfish inflow amount detected by the jellyfish inflow amount detecting means. Since the range of the jellyfish is adjusted, the volume reduction rate of the jellyfish in the jellyfish reservoir can be appropriately controlled by adjusting the range of the jellyfish in accordance with the jellyfish invasion amount. The contained jellyfish can be naturally extinguished at an optimal volume reduction rate within a range that satisfies water quality standards. Thereby, the jellyfish offshore process which fully utilizes the processing capability of the jellyfish which a jellyfish storage tank has can be performed. In addition, it is possible to suppress the occurrence of cases where the collected jellyfish must be landed and treated as waste in order to keep the water quality in the jellyfish storage tank within the standard, further reducing the jellyfish processing cost. be able to.

本願発明の上述の目的，その他の目的，特徴および利点は、図面を参照して行う以下の発明を実施するための形態の説明から一層明らかとなろう。 The above-described object, other objects, features, and advantages of the present invention will become more apparent from the following description of embodiments for carrying out the invention with reference to the drawings.
図１に、本願発明の一実施形態にかかるクラゲの洋上処理システムの概略構成を示す。
本願発明の一実施形態にかかるクラゲの洋上処理システム１００は、洋上でクラゲを貯留するためのクラゲ貯留槽１５０と、取水口付近に来襲したクラゲを誘導するクラゲ誘導網１１０と、クラゲ誘導網により誘導されたクラゲを洋上で回収するためのクラゲ回収台船１１２と、クラゲ回収台船により回収されたクラゲを吸引するクラゲ吸引ポンプ１１４と、クラゲ吸引ポンプにより吸引されたクラゲをクラゲ貯留槽に移送するクラゲ移送パイプ１１６とを備える。FIG. 1 shows a schematic configuration of a jellyfish offshore processing system according to an embodiment of the present invention.
A jellyfish offshore processing system 100 according to an embodiment of the present invention includes a jellyfish storage tank 150 for storing jellyfish on the ocean, a jellyfish guiding network 110 for guiding a jellyfish that has come near the water intake, and a jellyfish guiding network. Jellyfish collection stand 112 for collecting the guided jellyfish at sea, jellyfish suction pump 114 for sucking jellyfish collected by the jellyfish collection stand, and jellyfish sucked by the jellyfish suction pump are transferred to the jellyfish storage tank. And a jellyfish transfer pipe 116.
クラゲ吸引ポンプ１１４は、クラゲ回収台船により回収されたクラゲを傷つけることなくクラゲ貯留槽に移送するため、いわゆるフィッシュポンプが用いられ、洋上に設置される。 The jellyfish suction pump 114 is a so-called fish pump and is installed on the ocean in order to transfer the jellyfish recovered by the jellyfish recovery platform ship to the jellyfish storage tank without damaging them.
また、クラゲ移送パイプの途中には、クラゲ吸引ポンプによってクラゲとともに吸引された海水を、一部の海水を残して排出するためのセパレータ１２０を備える。 Further, a separator 120 is provided in the middle of the jellyfish transfer pipe to discharge the seawater sucked together with the jellyfish by the jellyfish suction pump while leaving a part of the seawater.
本願発明の一実施形態にかかるクラゲの洋上処理システム１００では、クラゲ貯留槽に流入するクラゲの量を検出できるようにするため、クラゲ移送出口配管１３０の径方向の中央部において、配管内を通過するクラゲを検知するクラゲ検知センサ１４０を備える。 In the jellyfish offshore processing system 100 according to one embodiment of the present invention, in order to detect the amount of jellyfish flowing into the jellyfish storage tank, the jellyfish transfer outlet pipe 130 passes through the pipe in the radial direction. The jellyfish detection sensor 140 which detects the jellyfish which does is provided.
クラゲ検知センサ１４０は、例えば赤外線反射式の光センサを用いることができ、これをクラゲ移送出口配管内の上方に設置することで、配管内をクラゲが通過したときにクラゲの表面からの反射光によってクラゲの通過が検知され、クラゲ通過信号が出力される。 As the jellyfish detection sensor 140, for example, an infrared reflection type optical sensor can be used. By installing this sensor above the jellyfish transfer outlet pipe, the reflected light from the surface of the jellyfish when the jellyfish passes through the pipe. Detects the passage of the jellyfish and outputs a jellyfish passage signal.
クラゲ検知センサ１４０より出力されたクラゲ通過信号は、コンピュータ１９０に入力され、コンピュータ１９０においてクラゲ流入量が演算される。
コンピュータ１９０によるクラゲ流入量の演算は、例えば、クラゲがクラゲ移送出口配管のクラゲ検知センサの直下を通過する標準通過速度と、平均的なクラゲの傘の直径と容積（または重量）との関係を示すクラゲ容積係数（または重量係数）をパラメータとして予め設定しておき、クラゲ検知センサにより検知されたクラゲ通過信号の信号継続時間に対して、設定されたクラゲの標準通過速度に基づいて検知されたクラゲの直径を演算し、演算されたクラゲの直径に対して、設定されたクラゲ容積係数（または重量係数）に基づいて、検知されたクラゲの容積（または重量）を演算する。
このようにして演算されたクラゲの容積（または重量）を設定された期間内で積算することでその期間内のクラゲの流入量を推定することができる。The jellyfish passage signal output from the jellyfish detection sensor 140 is input to the computer 190, and the computer 190 calculates the jellyfish inflow amount.
The calculation of the amount of jellyfish inflow by the computer 190 is, for example, the relationship between the standard passing speed at which the jellyfish passes directly under the jellyfish detection sensor in the jellyfish transfer outlet pipe, and the diameter and volume (or weight) of the average jellyfish umbrella. The jellyfish volume coefficient (or weight coefficient) indicated is set in advance as a parameter, and is detected based on the standard passing speed of the set jellyfish with respect to the signal continuation time of the jellyfish passing signal detected by the jellyfish detecting sensor. The jellyfish diameter is calculated, and the detected jellyfish volume (or weight) is calculated based on the set jellyfish volume coefficient (or weight coefficient) with respect to the calculated jellyfish diameter.
By integrating the volume (or weight) of the jellyfish thus calculated within a set period, the amount of jellyfish inflow within that period can be estimated.
ここで、複数のクラゲが連なってクラゲ検知センサの直下を通過する場合も考えられるので、クラゲ検知センサによるクラゲ通過信号の信号継続時間が一定時間を超えた場合は、複数のクラゲが連なっているものと判断して、平均的なクラゲの直径に相当する時間で分割してクラゲの容積（または重量）を推定する。 Here, since it may be possible that a plurality of jellyfish pass through directly under the jellyfish detection sensor, when the signal duration of the jellyfish passage signal by the jellyfish detection sensor exceeds a certain time, a plurality of jellyfish are connected. Judgment is made, and the volume (or weight) of the jellyfish is estimated by dividing by a time corresponding to the average diameter of the jellyfish.
なお、クラゲ移送出口配管を通過するクラゲは、必ずしも配管の中央を通過するとは限らないので、配管の径方向の中央部以外の両側にもクラゲ検知センサを設け、各センサにおいてクラゲ通過信号が出力された期間とタイミングとから総合的に判断してクラゲ流入量を推定することが好ましい。 The jellyfish that passes through the jellyfish transfer outlet pipe does not necessarily pass through the center of the pipe. Therefore, a jellyfish detection sensor is provided on both sides other than the center of the pipe in the radial direction, and a jellyfish passage signal is output from each sensor. It is preferable to estimate the jellyfish inflow amount comprehensively from the determined period and timing.
また、クラゲ検知センサとして、クラゲ移送パイプの出口配管に、配管内を径方向に走査して反射光を検出する光センサまたはラインセンサを設置し、クラゲが通過したときのクラゲの幅を検知し、その時間変化によりクラゲの大きさを計測してクラゲ流入量を検出するようにしてもよく、小型のテレビカメラを設置し、クラゲを２次元画像として検知してクラゲ流入量を検出するようにしてもよい。 In addition, as a jellyfish detection sensor, an optical sensor or line sensor that scans the inside of the pipe in the radial direction and detects reflected light is installed at the outlet pipe of the jellyfish transfer pipe to detect the width of the jellyfish when it passes. The jellyfish inflow may be detected by measuring the size of the jellyfish according to the change over time, or a small TV camera may be installed to detect the jellyfish inflow by detecting the jellyfish as a two-dimensional image. May be.
クラゲ移送出口配管１３０には、吸引されたクラゲとともにセパレータ１２０によって排出されなかった海水が通過する。このため、クラゲ検知センサは、配管内をクラゲとともに通過する海水によってクラゲ以外のところで反射光を検出して誤動作する可能性があり、クラゲ流入量を正しく検出できない場合が生ずるという問題がある。また、通過する海水によって光センサの表面が汚損され、クラゲの検出が困難となる場合が生ずるという問題がある。 Seawater that has not been discharged by the separator 120 along with the sucked jellyfish passes through the jellyfish transfer outlet pipe 130. For this reason, there is a problem that the jellyfish detection sensor may malfunction due to detection of reflected light other than the jellyfish due to seawater that passes through the pipe together with the jellyfish, and the jellyfish inflow amount may not be detected correctly. In addition, there is a problem that the surface of the optical sensor is soiled by the passing seawater and it may be difficult to detect jellyfish.
そこで、本実施形態では、クラゲ移送出口配管１３０の配管内において、クラゲ検知センサの設置位置よりも手前において海水を除去する水切りスリット１３２を備え、水切りスリットにより海水が除去されたクラゲはクラゲ検知センサ１４０が設置されたクラゲ通路１３４を通ってクラゲ貯留槽に流入させ、水切りスリットにより除去された海水は海水通路１３６を通ってクラゲ貯留槽に流入させるようにした。
このように、水切りスリットで分離された海水も海水通路を通ってクラゲ貯留槽に流入するようにしたので、クラゲ貯留槽の表層部に還流を形成する機能に影響を与えることがない。Therefore, in this embodiment, the jellyfish transfer outlet pipe 130 includes a draining slit 132 for removing seawater before the installation position of the jellyfish detection sensor, and the jellyfish from which the seawater has been removed by the draining slit is the jellyfish detection sensor. The seawater removed by the draining slit was caused to flow into the jellyfish reservoir through the seawater passage 136 through the jellyfish passage 134 in which 140 is installed.
Thus, since the seawater separated by the draining slit also flows into the jellyfish storage tank through the seawater passage, the function of forming a reflux in the surface portion of the jellyfish storage tank is not affected.
一方、本願発明の一実施形態にかかるクラゲ貯留槽１５０は、網地１５２によって籠状に形成され、回収されたクラゲを海水中に貯留できるようにするため、上端フレームをフロート１５４で海面に浮揚させ、下端フレームを錘１５６で沈めることで網地１５２を海水中に伸展させる。
このようなクラゲ貯留槽を、取水口付近の海水の流れを有する洋上に設置し、収容されたクラゲを下流側の網地に張り付かせることで早期に自然消滅させる。On the other hand, the jellyfish storage tank 150 according to an embodiment of the present invention is formed in a bowl shape by the net 152, and the upper end frame is floated to the sea surface by the float 154 so that the recovered jellyfish can be stored in seawater. Then, the lower end frame is submerged with the weight 156 to extend the net 152 into the seawater.
Such a jellyfish storage tank is installed on the ocean with the flow of seawater near the intake, and the housed jellyfish is pasted on the downstream netting to be naturally extinguished early.
また、クラゲ貯留槽１５０は、収容されたクラゲが急速に死滅することによる水質の変化を緩和するため、側面の網地には、海面から深さ方向の一部を目張りする目張りシート１６０を備え、クラゲ移送出口配管１３０からクラゲとともに流入する海水によって表層部に穏やかな還流が形成されるように構成している。
このような表層部の穏やかな還流により、収容された直後の元気なクラゲを一定期間活かした状態に保持し、その後運動能力の低下したクラゲが下層部に降りてきて下流側の網地に張り付いて消滅するというプロセスによってクラゲの減容を図ることで、水質の変化を緩和しつつ早期にクラゲを自然消滅させる。In addition, the jellyfish storage tank 150 includes a weather sheet 160 that stretches a part in the depth direction from the sea surface to the side netting in order to mitigate changes in water quality due to rapid death of the contained jellyfish. The seawater flowing together with the jellyfish from the jellyfish transfer outlet pipe 130 is configured to form a gentle reflux in the surface layer portion.
Such gentle reflux of the surface layer keeps the energetic jellyfish immediately after being accommodated for a certain period of time, after which the jellyfish with reduced exercise capacity descends to the lower layer and stretches on the downstream network. By reducing the volume of the jellyfish through the process of disappearing, the jellyfish is naturally extinguished early while mitigating changes in water quality.
ここで、クラゲ貯留槽の側面に設ける目張りシートの深さ方向の目張り範囲によって、クラゲ貯留槽に収容されたクラゲの減容速度がどのように変化するかを確認するため、一辺が１ｍの立方形状の貯留槽を用いてクラゲの貯留実験を行った。
その結果、図６に示すように、目張りシートの深さを０．３ｍ（貯留槽の深さの約３分の１）にしたときがクラゲの減容速度が最も早く、それ以上に深くするとクラゲの減容速度が低下していくことが確認された。
このように、クラゲ貯留槽に設ける目張りシートの深さを変えることで、クラゲ貯留槽に収容されたクラゲの減容速度を制御できることが確認されたので、本願発明では、クラゲ貯留槽の側面の目張りシートの深さ方向の目張り範囲を調節する目張り範囲調節機構を設けた。Here, in order to confirm how the volume reduction rate of the jellyfish stored in the jellyfish storage tank changes according to the depth range of the weathering sheet provided on the side surface of the jellyfish storage tank, a cube with a side of 1 m A jellyfish storage experiment was conducted using a shaped storage tank.
As a result, as shown in FIG. 6, when the depth of the weather sheet is set to 0.3 m (about one third of the depth of the storage tank), the volume reduction rate of the jellyfish is the fastest, and if it is deeper than that, It was confirmed that the jellyfish volume reduction rate decreased.
As described above, it was confirmed that the volume reduction rate of the jellyfish stored in the jellyfish storage tank can be controlled by changing the depth of the weather sheet provided in the jellyfish storage tank. A weathering range adjustment mechanism for adjusting the weathering range in the depth direction of the weathering sheet is provided.
図６の実験結果からも判るように、目張りシートの深さをクラゲ貯留槽の深さの約３分の１にしたときがクラゲの減容速度が最も早いことが確認されているので、この実施形態のクラゲ貯留槽１５０の目張り範囲調節機構は、図１に示すように、海面からクラゲ貯留槽の深さの約３分の１を目張りする固定の目張りシート１６０と、高さ方向の位置を変えることができる可動の目張りシート１７０とを備え、可動目張りシートの高さを下げることで、目張り範囲を深くしてクラゲの減容速度を抑制することができるようにした。 As can be seen from the experimental results in FIG. 6, it has been confirmed that the volume reduction rate of the jellyfish is the fastest when the depth of the weather sheet is about one third of the depth of the jellyfish reservoir. As shown in FIG. 1, the cover area adjusting mechanism of the jellyfish reservoir 150 of the embodiment includes a fixed cover sheet 160 that covers approximately one third of the depth of the jellyfish reservoir from the sea surface, and a position in the height direction. The movable weathering sheet 170 can be changed, and by reducing the height of the movable weathering sheet, the range of the weathering can be deepened and the volume reduction rate of the jellyfish can be suppressed.
この実施形態の目張り範囲調節機構は、可動目張りシートの高さ方向の位置を調節するため、錘の役目をする可動目張りシート下端フレーム１７４と、可動目張りシート上端フレーム１７２を吊り下げる可動目張りシート高さ調節用ワイヤ１７６と、ワイヤ１７６を巻き取る巻取機１７８とを備え、巻取機１７８によるワイヤの巻取量を調節することで、可動目張りシート１７０を上下に移動させ、クラゲ貯留槽の目張り範囲を調節する。
従って、クラゲ検知センサ１４０により検出されたクラゲの流入量に応じて、巻取機１７８によるワイヤの巻取量を制御することで、クラゲ貯留槽の目張り範囲が調節され、最適なクラゲの減容速度を設定することができる。The weathering range adjustment mechanism of this embodiment adjusts the position of the movable weathering sheet in the height direction, so that the movable weathering sheet lower end frame 174 serving as a weight and the movable weathering sheet upper end frame 172 are suspended. A wire 176 for adjusting the thickness and a winder 178 that winds the wire 176, and by adjusting the winding amount of the wire by the winder 178, the movable weather sheet 170 is moved up and down, and the jellyfish storage tank Adjust the cover area.
Therefore, the amount of winding of the wire by the winder 178 is controlled in accordance with the amount of inflow of the jellyfish detected by the jellyfish detection sensor 140, so that the range of the jellyfish storage tank is adjusted and the optimum volume reduction of the jellyfish. Speed can be set.
この実施形態の目張り範囲調節機構においては、巻取機１７８はコンピュータ１９０に接続されており、コンピュータ１９０からの指令に基づいて巻取機１７８の巻取量を制御することで、クラゲ貯留槽の目張りシートによる目張り範囲を指定された目張り範囲に設定することができる。 In the weathering range adjustment mechanism of this embodiment, the winder 178 is connected to the computer 190, and by controlling the winding amount of the winder 178 based on a command from the computer 190, the jellyfish storage tank. It is possible to set the range of the cover by the cover sheet to the specified range.
また、本願発明の一実施形態にかかるクラゲの洋上処理システム１００は、クラゲ貯留槽の縁辺部から表層部に注水する注水装置として注水パイプ１８０を備える。
注水パイプ１８０には、クラゲ貯留槽の縁辺部からクラゲ貯留槽の表層部に海水を注水する還流生成用注水ノズル１８４を複数個所に備え、クラゲ貯留槽の表層部に注水することで表層部に還流を生成させることができる。これにより、クラゲ移送出口配管１３０からクラゲとともに流入する海水によって生成される表層部の穏やかな還流の形成状況を改善して局所的な水質の濃度差を緩和することができる。
また、注水パイプ１８０には、クラゲ貯留槽の上面からクラゲ貯留槽の表面に散水する消泡用散水ノズル１８６を備え、クラゲ貯留槽の表層部においてクラゲ同士が接触することにより生じた泡を消泡することができ、大量のクラゲが来襲したときの景観等の環境への影響を改善することができる。Moreover, the jellyfish offshore processing system 100 concerning one Embodiment of this invention is equipped with the water injection pipe 180 as a water injection apparatus which injects water from the edge part of a jellyfish storage tank to a surface layer part.
The water injection pipe 180 is provided with a plurality of reflux generating water injection nozzles 184 for injecting seawater from the edge of the jellyfish storage tank to the surface layer of the jellyfish storage tank, and by pouring water into the surface layer of the jellyfish storage tank, Reflux can be generated. As a result, it is possible to improve the formation of a gentle reflux in the surface layer portion generated by the seawater that flows in along with the jellyfish from the jellyfish transfer outlet pipe 130, and to reduce the local water quality concentration difference.
In addition, the water injection pipe 180 includes a defoaming water spray nozzle 186 for spraying water from the upper surface of the jellyfish storage tank to the surface of the jellyfish storage tank so as to eliminate bubbles generated by the jellyfish coming into contact with each other in the surface layer portion of the jellyfish storage tank. It can foam and can improve the environmental impact such as landscape when a large amount of jellyfish attack.
注水パイプ１８０は、注水パイプに海水を給水するための給水ポンプ１８６に接続されており、給水ポンプ１８６を制御することで、クラゲ貯留槽の表層部に注水する注水量を調節することができる。
従って、クラゲ検知センサ１４０により検出されたクラゲの流入量に応じて給水ポンプ１８６による給水量を制御することで、クラゲ貯留槽の表層部の還流の形成状況を最適化することができる。The water injection pipe 180 is connected to a water supply pump 186 for supplying seawater to the water injection pipe. By controlling the water supply pump 186, the amount of water injected into the surface layer of the jellyfish storage tank can be adjusted.
Therefore, by controlling the amount of water supplied by the water supply pump 186 according to the amount of inflow of jellyfish detected by the jellyfish detection sensor 140, it is possible to optimize the formation of reflux in the surface portion of the jellyfish storage tank.
この実施形態の注水装置においては、給水ポンプ１８６はコンピュータ１９０に接続されており、コンピュータ１９０からの指令に基づいて給水ポンプ１８６の給水量を制御することで、クラゲ貯留槽の表層部に注水する注水量を指定された注水量に設定することができる。 In the water injection device of this embodiment, the water supply pump 186 is connected to the computer 190, and water is injected into the surface layer portion of the jellyfish storage tank by controlling the water supply amount of the water supply pump 186 based on a command from the computer 190.

図４に、本願発明の一実施形態にかかる注水装置の概略構成を示す。図４（１）はクラゲ貯留槽が丸型の場合の構成例であり、図４（２）はクラゲ貯留槽が角型の場合の構成例である。
図４に示すように、クラゲ貯留槽１５０の表層部には、クラゲ移送出口配管１３０からクラゲとともに流入する海水によって穏やかな還流が常時形成されている。
これに対して、クラゲ貯留槽１５０の縁辺部に設置された注水パイプ１８０の複数個所に設けられた還流生成用注水ノズル１８２からクラゲ貯留槽の表層部に注水することにより、クラゲ貯留槽の表層部に形成されている穏やかな還流に対して調整流が加わり、表層部の還流が補強される。これにより、クラゲが大量に来襲した場合に、還流生成用注水ノズルからクラゲ貯留槽の表層部への注水量を増やすことで、クラゲ貯留槽の表層部において生ずる局所的な水質の濃度差を緩和することができる。
また、クラゲ貯留槽１５０の縁辺部に設置された注水パイプ１８０の複数個所において、クラゲ貯留槽の上面の縁辺部から中心部に向かって延設された消泡用散水ノズル１８４からクラゲ貯留槽の表面に散水することによって、クラゲ貯留槽の表層部においてクラゲ同士が接触することにより生じた泡を消泡することができ、大量のクラゲが来襲したときの景観等の環境への影響を改善することができる。In FIG. 4, schematic structure of the water injection apparatus concerning one Embodiment of this invention is shown. FIG. 4A is a configuration example when the jellyfish storage tank is a round shape, and FIG. 4B is a configuration example when the jellyfish storage tank is a square shape.
As shown in FIG. 4, a gentle reflux is always formed in the surface layer portion of the jellyfish storage tank 150 by the seawater that flows together with the jellyfish from the jellyfish transfer outlet pipe 130.
On the other hand, the surface layer of the jellyfish storage tank is injected by injecting water into the surface layer part of the jellyfish storage tank from the reflux generating water injection nozzles 182 provided at a plurality of locations of the water injection pipes 180 installed at the edge of the jellyfish storage tank 150. Regulated flow is added to the gentle reflux formed in the part, and the reflux in the surface layer part is reinforced. As a result, when a large amount of jellyfish invade, the amount of water injected from the water injection nozzle for reflux generation to the surface layer of the jellyfish storage tank is increased, thereby mitigating local water quality concentration differences that occur in the surface layer of the jellyfish storage tank. can do.
Further, at a plurality of locations of the water injection pipes 180 installed at the edge of the jellyfish reservoir 150, the defoaming water spray nozzle 184 extending from the edge of the upper surface of the jellyfish reservoir toward the center of the jellyfish reservoir 184 By sprinkling water on the surface, it is possible to eliminate bubbles generated by jellyfish coming into contact with each other in the surface layer of the jellyfish storage tank, improving the environmental impact such as landscape when a large amount of jellyfish attack be able to.
図４において、還流生成用注水ノズル１８２は、クラゲ貯留槽の縁辺部の４箇所に設けているが、これは還流生成用注水ノズルによる還流形成の調整流の機能を説明するために例示したものであって、還流生成用注水ノズルをクラゲ貯留槽の表層部の具体的どの部分にどのように設置するかは、クラゲ貯留槽の形状や設置場所の環境条件に応じて表層部において適切に還流が形成されるように決定される。
なお、さまざまな設置条件に対応できるように多数の還流生成用注水ノズルを設け、それぞれの注入量を個別に調節できるようにしてもよい。これにより、さまざまなクラゲ貯留槽の形状や設置場所の環境条件に対応できる柔軟なクラゲの洋上処理システムを構成することができる。In FIG. 4, the reflux generation water injection nozzles 182 are provided at four positions on the edge of the jellyfish storage tank, and this is illustrated to explain the function of the adjustment flow for the reflux formation by the reflux generation water injection nozzle. And how to install the water injection nozzle for reflux generation in the specific part of the surface layer part of the jellyfish storage tank depends on the shape of the jellyfish storage tank and the environmental conditions of the installation location. Is determined to be formed.
In addition, a large number of water injection nozzles for reflux generation may be provided so as to cope with various installation conditions, and the respective injection amounts may be individually adjusted. Thereby, the flexible jellyfish offshore processing system which can respond to the environmental conditions of the shape and installation location of various jellyfish storage tanks can be comprised.
また、図４において、消泡用散水ノズル１８４は、クラゲ貯留槽の上面において縁辺部の４箇所から中心部に向かって延設されているが、これは消泡用散水ノズルによる消泡散水の機能を説明するために例示したものであって、消泡用散水ノズルをクラゲ貯留槽の上面のどの部分にどのように設置するかについても、クラゲ貯留槽の形状や設置場所の環境条件に応じて適切に消泡できるように決定される。 Moreover, in FIG. 4, although the defoaming watering nozzle 184 is extended toward the center part from four places of the edge part in the upper surface of a jellyfish storage tank, this is the defoaming watering by a defoaming watering nozzle. It is an example for explaining the function, and depending on the shape of the jellyfish storage tank and the environmental conditions of the installation location, how to install the defoaming watering nozzle on which part of the upper surface of the jellyfish storage tank It is determined so that it can be properly removed.
また、図４において、還流生成用注水ノズル１８２と消泡用散水ノズル１８４とは、図面の簡略化のため同一の注水パイプ１８０に接続されるものとして説明したが、還流生成用注水ノズルと消泡用散水ノズルをそれぞれ個別に配管し、それぞれの配管に対して個別に給水ポンプを備えるようにすれば、還流形成のための注水量の調節と消泡のための散水量の調節を個別に行うことができ、クラゲ貯留槽へのクラゲの流入量の変化に対してより柔軟に対応することが可能となる。 In FIG. 4, the reflux generation water injection nozzle 182 and the defoaming water spray nozzle 184 have been described as being connected to the same water injection pipe 180 for the sake of simplification of the drawing. If each of the foaming nozzles is piped individually and a water supply pump is provided for each pipe, adjustment of the amount of water injected for reflux formation and adjustment of the amount of water sprayed for defoaming are performed separately. It can be performed, and it becomes possible to respond more flexibly to changes in the amount of jellyfish flowing into the jellyfish storage tank.
次に、上述したようなクラゲの洋上処理システム１００を用いて、クラゲ検知センサにより検出されたクラゲ流入量に対応して、クラゲ貯留槽の目張り範囲をどのように調整し、クラゲ貯留槽の表層部への注水量をどのように調節すればよいかについて説明する。 Next, using the jellyfish offshore processing system 100 as described above, the surface area of the jellyfish storage tank is adjusted according to the amount of the jellyfish storage tank according to the jellyfish inflow amount detected by the jellyfish detection sensor. How to adjust the amount of water injected to the part will be described.
図５に、本願発明の一実施形態にかかるクラゲの洋上処理システムのコンピュータ１９０による制御手順の例を示す。
本願発明の一実施形態にかかる制御手順（Ｓ１００）は、最初に、上述したクラゲ検知センサによるクラゲ通過信号に基づいてコンピュータ１９０において演算された前回から今回までのクラゲ流入量を取得する（Ｓ１０２）。
次に、前回のクラゲ残存量、前回の目張り範囲設定、前回の注水量設定に基づいて、前回から今回までのクラゲ減容量を推定する（Ｓ１０４）。このクラゲ減容量の推定は、目張り範囲とクラゲ減容速度の関係を測定したデータ（例えば、図６）、注水量とクラゲ減容速度の関係を測定したデータ等を用いて行う。FIG. 5 shows an example of a control procedure by the computer 190 of the jellyfish offshore processing system according to an embodiment of the present invention.
In the control procedure (S100) according to an embodiment of the present invention, first, the jellyfish inflow amount from the previous time to the current time calculated in the computer 190 is acquired based on the jellyfish passage signal from the jellyfish detection sensor described above (S102). .
Next, the jellyfish reduction capacity from the previous time to the current time is estimated based on the previous jellyfish remaining amount, the previous setting of the eyelid range, and the previous water injection amount setting (S104). The estimation of the jellyfish volume reduction is performed using data (for example, FIG. 6) obtained by measuring the relationship between the eyelid range and the jellyfish volume reduction rate, data obtained by measuring the relationship between the water injection amount and the jellyfish volume reduction rate, and the like.
次に、取得されたクラゲ流入量と推定されたクラゲ減容量に基づいて、現在のクラゲ貯留槽内のクラゲ残存量を演算する（Ｓ１０６）。
そして、クラゲ貯留槽の現在のクラゲ残存量における水質負荷を予測する（Ｓ１０８）。この水質負荷の予測は、クラゲ残存量とクラゲ貯留槽内の水質分布の関係を測定したデータ、クラゲ貯留槽の設置環境における海流データ（例えば、図７）等を用いて行う。Next, the remaining amount of jellyfish in the current jellyfish reservoir is calculated based on the acquired amount of jellyfish inflow and the estimated jellyfish reduction capacity (S106).
And the water quality load in the current amount of jellyfish remaining in the jellyfish reservoir is predicted (S108). The prediction of the water quality load is performed using data obtained by measuring the relationship between the remaining amount of jellyfish and the water quality distribution in the jellyfish storage tank, ocean current data (for example, FIG. 7) in the installation environment of the jellyfish storage tank, and the like.
その結果、クラゲ貯留槽内の水質を所定の水質基準を満たすように維持するためにクラゲ貯留槽の目張り範囲を調節する必要があると判断された場合は（Ｓ１１０）、目張り範囲とクラゲ減容速度の関係を測定したデータに基づいて最適な目張り範囲を演算し（Ｓ１１２）、クラゲ貯留槽の目張り範囲調節機構を制御して目張りシートによる目張り範囲を演算された最適な目張り範囲に設定する（Ｓ１１４）。 As a result, when it is determined that it is necessary to adjust the cover area of the jellyfish storage tank in order to maintain the water quality in the jellyfish storage tank so as to satisfy the predetermined water quality standard (S110), the cover area and jellyfish volume reduction Based on the data obtained by measuring the speed relationship, the optimum range of the range is calculated (S112), and the range range adjustment mechanism of the jellyfish storage tank is controlled to set the range of the range of the ranged sheet to the calculated optimal range of range ( S114).
また、クラゲ貯留槽内の水質を所定の水質基準を満たすように維持するためにクラゲ貯留槽の表層部に注水する注水量を調節する必要があると判断された場合は（Ｓ１１６）、上記設定された目張り範囲において注水量とクラゲ減容速度の関係を測定したデータに基づいて最適な注水量を演算し（Ｓ１１８）、注水装置の給水ポンプを制御してクラゲ貯留槽の表層部に注入する注水量を演算された最適な注水量に設定する（Ｓ１２０）。
以上のような制御を、設定周期が経過する毎に（例えば、一日に一回）、最初から繰り返す（Ｓ１２２）。In addition, when it is determined that it is necessary to adjust the amount of water injected into the surface layer of the jellyfish storage tank in order to maintain the water quality in the jellyfish storage tank so as to satisfy the predetermined water quality standard (S116), the above setting The optimum water injection amount is calculated based on the data obtained by measuring the relationship between the water injection amount and the jellyfish volume reduction rate within the specified range (S118), and the water supply pump of the water injection device is controlled and injected into the surface layer of the jellyfish storage tank. The water injection amount is set to the calculated optimal water injection amount (S120).
The above control is repeated from the beginning every time the set cycle elapses (for example, once a day) (S122).
なお、上記制御手順では説明を省略したが、予測されたクラゲ貯留槽の水質負荷が目張り範囲の調節や注水量の調節によって改善できる範囲を超えていることが確認された場合は、その旨を作業者に通知し、クラゲの移送先を陸上の廃棄物保管庫に切替えたり、クラゲ貯留槽に収容されている一部のクラゲを陸上の廃棄物保管容器に回収したりするなどの措置を行う。 In addition, although explanation was omitted in the above control procedure, if it is confirmed that the predicted water quality load of the jellyfish storage tank exceeds the range that can be improved by adjusting the cover area or adjusting the amount of water injected, that fact is indicated. Notify the worker and take measures such as switching the jellyfish transfer destination to an onshore waste storage, or collecting some jellyfish contained in the jellyfish storage tank to an onshore waste storage container. .
また、上記制御手順では、現在のクラゲ残存量の演算は、前回のクラゲ残存量に基づいてクラゲ減容量を推定し、新たなクラゲ流入量と推定されたクラゲ減容量から現在のクラゲ残存量を決定するものとして説明したが、これは個々のクラゲの減容速度がクラゲ貯留槽における貯留期間によっては大きく変化せず、クラゲ貯留槽に残存しているクラゲの総量によってクラゲの減容量を決定できることを前提としたものである。
個々のクラゲの減容速度がクラゲ貯留槽における貯留期間によって大きく変化する場合には、各制御周期毎のクラゲ流入量に対応するクラゲ残存量の履歴を保存するようにし、各制御周期毎のクラゲ残存量についてそれぞれの貯留期間に対応したクラゲ減容量によってクラゲ残存量を更新し、各制御周期毎のクラゲ残存量の総和として全体のクラゲ残存量を演算するようにすればよい。この場合において、各制御周期毎のクラゲ残存量のなかでクラゲ残存量が一定量以下となったものについては既にクラゲが消滅したとして履歴から抹消するようにしてもよい。Also, in the above control procedure, the current jellyfish remaining amount is calculated by estimating the jellyfish reduction capacity based on the previous jellyfish residual amount, and calculating the current jellyfish residual amount from the new jellyfish inflow amount and the estimated jellyfish reduction amount. As explained above, this means that the volume reduction rate of individual jellyfish does not change greatly depending on the storage period in the jellyfish storage tank, and the jellyfish volume reduction can be determined by the total amount of jellyfish remaining in the jellyfish storage tank. It is based on this.
If the volume reduction rate of individual jellyfish varies greatly depending on the storage period in the jellyfish storage tank, the jellyfish remaining amount history corresponding to the jellyfish inflow amount for each control cycle is stored, and the jellyfish for each control cycle is stored. What is necessary is just to update the jellyfish residual amount by the jellyfish reduction | decrease capacity | capacitance corresponding to each storage period about the residual amount, and to calculate the whole jellyfish residual amount as a sum total of the jellyfish residual amount for every control period. In this case, among the remaining amount of jellyfish for each control cycle, the remaining amount of the jellyfish may be erased from the history assuming that the jellyfish have already disappeared.
以上のように、この発明のクラゲの洋上処理システム１００によれば、クラゲ検知センサにより検出されたクラゲ流入量に対応して、クラゲ貯留槽の目張りシートの目張り範囲と注水量を適切に調節することで、クラゲ貯留槽において水質基準を満たす範囲の最速でクラゲを自然消滅させることができるので、クラゲが大量に来襲した場合でも、陸上に水揚げして廃棄物として処理しなければならなくなる事態を最大限に回避することができ、クラゲの処理コストを更に抑制することが可能となる。 As mentioned above, according to the jellyfish offshore processing system 100 of this invention, according to the jellyfish inflow amount detected by the jellyfish detection sensor, the weathering range and water injection amount of the weathering sheet of a jellyfish storage tank are adjusted appropriately. This means that jellyfish can be extinguished spontaneously at the fastest speed that meets the water quality standards in the jellyfish storage tank, so that even if a large number of jellyfish invade, it must be landed and treated as waste. It can be avoided to the maximum, and the jellyfish processing cost can be further suppressed.
上記実施形態では、コンピュータによって、クラゲ検知手段により検出されたクラゲ流入量に基づいてクラゲ貯留槽の目張り範囲や表層部への注水量が自動的に制御されるものとして説明したが、本願発明はこれに限定されるものではなく、コンピュータによってクラゲ検知センサからの信号に基づいてクラゲ流入量を演算して画面表示し、これに基づいて作業者がクラゲ貯留槽の目張り範囲や表層部への注水量を人為的に調節するようにしてもよい。この場合には、目張り範囲調節機構の巻取機は必ずしも電動の巻取機である必要はなく、手巻きのウインチ等を用いることもできる。 In the above embodiment, the computer has been described as automatically controlling the amount of water injected into the jellyfish storage tank and the surface layer portion based on the jellyfish inflow amount detected by the jellyfish detection means. The jellyfish inflow amount is calculated by a computer based on the signal from the jellyfish detection sensor and displayed on the screen. Based on this, the operator can inject the jellyfish storage tank into the cover area or surface layer. The amount of water may be artificially adjusted. In this case, the winder of the weathering range adjusting mechanism is not necessarily an electric winder, and a manually wound winch or the like can be used.
上記実施形態では、目張り範囲調節機構は、固定の目張りシートと可動の目張りシートを用い、可動の目張りシートを上下させることで目張り範囲を調節するものとして説明したが、クラゲ貯留槽の側面の海面から深さ方向の目張り範囲を調節できるものであればどのようなものでもよく、例えば巻取式の目張りシートを用いて巻取量を変化させることで目張り範囲を調節するようにしてもよい。 In the above embodiment, the description has been given that the weathering range adjustment mechanism uses a fixed weathering sheet and a movable weathering sheet, and adjusts the weathering range by moving the movable weathering sheet up and down, but the sea surface on the side surface of the jellyfish storage tank Any material can be used as long as it can adjust the depth range in the depth direction. For example, the range may be adjusted by changing the winding amount using a winding type weathering sheet.
上記実施形態では、注水装置の注水量を調節することによってクラゲ貯留槽の表層部の還流の形成状況を制御するものとして説明したが、クラゲ吸引ポンプによりクラゲとともに吸引された海水を排出するセパレータにおいて海水排出量を調節可能なものとし、この海水排出量を調節することで、クラゲ貯留槽の表層部の還流の形成状況を制御するようにしてもよく、注水装置による注水量の調節とセパレータによる海水排出量の調節を組合せてクラゲ貯留槽の表層部の還流の形成状況を制御するようにしてもよい。
なお、セパレータにおける海水排出量の調節は、例えば、セパレータの海水を排出する部分にスライド式のシャッタを設けて排水面積を調節することによって実現することができる。In the above embodiment, it is described that the formation state of the reflux of the surface portion of the jellyfish storage tank is controlled by adjusting the amount of water injected by the water injection device, but in the separator that discharges the seawater sucked together with the jellyfish by the jellyfish suction pump. The amount of seawater discharged can be adjusted, and by adjusting the amount of seawater discharged, the formation of reflux in the surface layer of the jellyfish storage tank may be controlled. You may make it control the formation condition of the reflux of the surface layer part of a jellyfish storage tank combining adjustment of seawater discharge.
The adjustment of the seawater discharge amount in the separator can be realized, for example, by adjusting the drainage area by providing a slide type shutter at the portion of the separator that discharges the seawater.
上記実施形態では、クラゲ貯留槽の表層部には、クラゲ移送出口配管からクラゲとともに流入する海水によって穏やかな還流が常時形成されており、これに対して注水装置の還流生成用注水ノズルからクラゲ貯留槽の表層部に注水することで表層部の還流を補強し、還流の形成状況を改善するものとして説明したが、本願発明はこれに限定されるものではなく、クラゲ貯留槽の表層部の還流形成に対してクラゲ移送出口配管からクラゲとともに流入する海水は寄与しないものであって、主として注水装置の還流生成用注水ノズルからクラゲ貯留槽の表層部に注水することによって表層部に還流を生成させるものであってもよい。 In the above embodiment, a gentle reflux is always formed by the seawater that flows in along with the jellyfish from the jellyfish transfer outlet pipe in the surface layer portion of the jellyfish storage tank. It was explained that the reflux of the surface layer part was reinforced by pouring water into the surface part of the tank, and the formation state of the reflux was improved, but the present invention is not limited to this, and the reflux of the surface part of the jellyfish storage tank The seawater that flows in along with the jellyfish from the jellyfish transfer outlet pipe does not contribute to the formation, and the surface layer part generates reflux mainly by pouring water from the water injection nozzle for reflux generation of the water injection device to the surface layer part of the jellyfish storage tank. It may be a thing.
上記実施形態では、クラゲ検知センサとして、光センサを用いるものとして説明したが、本願発明はこれに限定されるものではなく、配管内を通過するクラゲを検知できるものである限りどのようなセンサを用いてもよく、例えばクラゲの表面からの超音波の反射を検知することによりクラゲの流入量を検出するようにしてもよい。 In the above embodiment, the optical sensor is used as the jellyfish detection sensor. However, the present invention is not limited to this, and any sensor can be used as long as it can detect the jellyfish passing through the pipe. For example, the amount of jellyfish inflow may be detected by detecting the reflection of ultrasonic waves from the surface of the jellyfish.
上記実施形態では、クラゲ流入量検出手段として、クラゲ移送出口配管にクラゲ検知センサを設けるものとして説明したが、本願発明はこれに限定されるものではなく、例えば取水口付近を撮像するテレビカメラを備え、その画像を処理することで取水口付近に来襲しているクラゲの概算量を検出し、これに基づいてクラゲ貯留槽に流入するクラゲ流入量を推定するようにしてもよく、本願発明の効果を奏する。 In the above embodiment, the jellyfish inflow detection means has been described as providing a jellyfish detection sensor in the jellyfish transfer outlet pipe. However, the present invention is not limited to this, and for example, a television camera that captures the vicinity of a water intake is used. It is possible to detect the approximate amount of jellyfish that has come near the water intake by processing the image, and to estimate the jellyfish inflow amount flowing into the jellyfish reservoir based on this, There is an effect.
以上のように、本願発明によれば、クラゲが大量に来襲した場合においても、クラゲ貯留槽に収容されたクラゲの減容速度と貯留槽内の海水の流れの状況を、来襲するクラゲの量に応じて制御することにより、水質の変化を緩和することができる。これにより、水質基準を満たす範囲内で処理可能なクラゲの量を従来よりも多くすることができ、貯留槽を小型化したり、廃棄物として処理されるクラゲの量を低減することができる。また、クラゲ消滅時の景観上好ましくない泡等の発生を軽減することができ、環境への影響が可能な限り小さくなるように制御可能な状況下でクラゲの洋上処理を実施することができる。 As described above, according to the present invention, even when a large amount of jellyfish strikes, the amount of jellyfish that attacks the volume reduction rate of the jellyfish contained in the jellyfish reservoir and the state of the flow of seawater in the reservoir. By controlling according to this, the change in water quality can be mitigated. Thereby, the quantity of the jellyfish which can be processed within the range which satisfy | fills a water quality standard can be increased more than before, a storage tank can be reduced in size, and the quantity of the jellyfish processed as waste can be reduced. Moreover, generation | occurrence | production of the bubble etc. which are unpreferable on the landscape at the time of a jellyfish extinction can be reduced, and the jellyfish offshore process can be implemented in the condition which can be controlled so that the influence on an environment may become as small as possible.
尚、本願発明は上述した各実施形態に限定されるものではなく、本願発明の効果を奏する限り、各実施形態で述べた構成要素を適宜入れ替えたり、新たな構成要素を追加したり、一部の構成要素を削除したりしてもよいことはいうまでもない。 Note that the present invention is not limited to the above-described embodiments, and as long as the effects of the present invention are achieved, the constituent elements described in the respective embodiments are appropriately replaced, new constituent elements are added, or a part thereof It goes without saying that the constituent elements may be deleted.
