In order to be in the right attitude.

また、移動装置１が止水蓋２を保持した状態における、止水蓋２の、移動装置１の操作機構７に対向する位置には、充水機構８を設けてある。これはすなわち、移動装置１の中心軸と止水蓋２の中心軸が一致したときに、操作機構７の中心軸と充水機構８の中心軸も一致するということである。図４に示すように、充水機構８は、充水口８１と、弁体８２と、被係合部８３を有している。より詳しくは、止水蓋２に形成した孔に、後側に向けて開口する有底筒状の外筒体８４を嵌め込んであり、外筒体８４の底部に形成した前後方向（止水蓋２の表裏方向）に貫通する孔が充水口８１となっている。弁体８２は、充水口８１よりも直径が大きな円盤状のものであり、前側に環状のパッキン８２１を取り付けてあって、パッキン８２１が充水口８１の周囲の面に当接することで、充水口８１を後側（止水蓋２の表側）から塞ぐものである。また、弁体８２の前側には、前側に向けて開口する筒状で充水口８１に丁度嵌まる直径の内筒体８２２を設けてある。この内筒体８２２の側周面の後側部には、周方向に等間隔に四つの通水口８２３を形成してある。さらに、弁体８２の後側には、後側に向けて延びるロッド８５を設けてあり、外筒体８４の後端部が、外筒体８４と同直径の閉止板８４１により塞いであって、ロッド８５は閉止板８４１の中央に形成した孔を貫通して後側に突出している。すなわち、弁体８２は外筒体８４と閉止板８４１に囲まれた空間内に納まり、その空間の範囲内で前後方向（止水蓋２の表裏方向）に移動可能である。また、閉止板８４１の、ロッド８５の貫通部の周囲には、前後方向に貫通する流入口８４２を形成してある。そして、この空間内の、弁体８２と閉止板８４１の間に、ロッド８５に外挿してコイルバネからなる付勢部材８６を設けてある。付勢部材８６により、弁体８２が充水口８１（止水蓋２の表側）に向けて押圧されている。また、ロッド８５の後端に、被係合部８３を設けてあり、弁体８２と被係合部８３とは、ロッド８５で接続されて一体となっている。被係合部８３は、後側（操作機構７側）に向けて開口する有底筒状のものであって、その内径は、係合部７１の外径よりも大きく、爪部７４が上下に広がった状態の係合部７１が丁度納まる大きさである。被係合部８３の後側端の周縁部には、前方内周側に向けて突出する突起部８３１を有している。突起部８３１の内周側面は、後側（開口側）に向けて広がる形状となっており、最挟部（突起部８３１の先端部）の内径は、操作機構７の係合部７１が通過可能であるが、爪部７４が展開した状態の上下幅よりは狭い大きさである。また、被係合部８３の側周面の上下位置には、それぞれ円形の貫通孔８７を形成してある。   Further, a water charging mechanism 8 is provided at a position of the water blocking lid 2 facing the operation mechanism 7 of the moving device 1 in a state where the moving device 1 holds the water blocking lid 2. That is, when the central axis of the moving device 1 and the central axis of the water blocking lid 2 coincide with each other, the central axis of the operation mechanism 7 and the central axis of the water charging mechanism 8 also coincide with each other. As shown in FIG. 4, the water charging mechanism 8 has a water charging port 81, a valve body 82, and an engaged portion 83. More specifically, a bottomed cylindrical outer cylinder 84 opened toward the rear side is fitted in the hole formed in the water blocking lid 2 and formed in the bottom of the outer cylinder 84 A hole penetrating in the front and back direction of the lid 2 is the water filling port 81. The valve body 82 has a disk shape having a diameter larger than that of the water charging port 81, and an annular packing 821 is attached on the front side, and the packing 821 contacts the surface around the water charging port 81. 81 is closed from the rear side (front side of the water blocking lid 2). Further, on the front side of the valve body 82, an inner cylindrical body 822 having a cylindrical shape that opens toward the front side and having a diameter that just fits into the water charging port 81 is provided. On the rear side of the side circumferential surface of the inner cylindrical body 822, four water holes 823 are formed at equal intervals in the circumferential direction. Furthermore, a rod 85 extending rearward is provided on the rear side of the valve body 82, and the rear end of the outer cylinder 84 is closed by a closing plate 841 having the same diameter as the outer cylinder 84. The rod 85 projects rearward through a hole formed at the center of the closing plate 841. That is, the valve body 82 is accommodated in the space surrounded by the outer cylindrical body 84 and the closing plate 841 and is movable in the front-rear direction (front and back direction of the water blocking lid 2) within the range of the space. Further, an inlet 842 penetrating in the front-rear direction is formed around the penetrating portion of the rod 85 of the closing plate 841. And in this space, between the valve body 82 and the closing plate 841, an urging member 86 consisting of a coil spring is provided by extrapolating the rod 85. The valve body 82 is pressed toward the water filling port 81 (front side of the water blocking lid 2) by the biasing member 86. Further, an engaged portion 83 is provided at the rear end of the rod 85, and the valve body 82 and the engaged portion 83 are connected by the rod 85 and integrated. The engaged portion 83 has a bottomed cylindrical shape that opens toward the rear side (the operation mechanism 7 side), and the inner diameter thereof is larger than the outer diameter of the engaging portion 71, and the claw portion 74 is vertically The engaging portion 71 in a state of being expanded to a size that fits exactly. At the peripheral edge portion of the rear end of the engaged portion 83, there is provided a projecting portion 831 which protrudes toward the front inner peripheral side. The inner peripheral side surface of the projection 831 is shaped to expand toward the rear side (opening side), and the inner diameter of the rearmost portion (the tip of the projection 831) passes through the engagement portion 71 of the operation mechanism 7 Although possible, the size is smaller than the upper and lower width of the expanded state of the claws 74. Further, circular through holes 87 are formed at the upper and lower positions of the side peripheral surface of the engaged portion 83, respectively.

次に、このように構成した移動装置１によって、止水蓋２を水中搬送する方法について説明する。水中の所定箇所に設置された止水蓋２に対して、まず、操作者がカメラ１１の画像を見ながら移動装置１を遠隔操作して、図１（ａ）に示すように、移動装置１を止水蓋２の後側に位置させる。移動装置１のカメラ１１の前側には、ケース１３に描いた移動装置１の照準部１２が位置しているので、カメラ１１の画像には、常にこの十字形の照準部１２が映し出された状態である。そして、カメラ１１を止水蓋２の覗き窓２１に対向させると、覗き窓２１を通して、止水蓋２の十字形の照準部２２が映し出される。この状態で、移動装置１の位置と姿勢を調整して、カメラ１１の画像を通して移動装置１の照準部１２と止水蓋２の照準部２２を重ね合わせれば、移動装置１の中心軸と止水蓋２の中心軸が一致し、移動装置１の連結部４と止水蓋２の被連結部５が前後に対向する。そして、ここから移動装置１を前進させれば、移動装置１の三つの連結部４がそれぞれ止水蓋２の三つのガイド部６の挿入穴６１に挿入される。この際、対流などの影響で移動装置１の照準部１２と止水蓋２の照準部２２が多少ずれていたとしても、ガイド部６の挿入穴６１が開口側に向けてラッパ状に広がっているので、連結部４は支障なく挿入穴６１に挿入される。そして、図１（ｂ）に示すように、連結部４が被連結部５に当接したら、連結部４の電源をオンにすることで、磁力が発生し、被連結部５が吸着されて、移動装置１により止水蓋２が保持され、水中搬送が可能となる。一方、移動装置１を止水蓋２から離脱させるには、止水蓋２を所定箇所に設置した後、連結部４の電源をオフにすることで、磁力が消滅するので、そのまま移動装置１を後退させて、ガイド部６の挿入穴６１から連結部４を引き抜けばよい。このように、連結部４の電源のオンオフによって、被連結部５に対して連結部４が着脱するものであり、移動装置１により止水蓋２を確実に保持して水中搬送することができ、また移動装置１を止水蓋２から容易に離脱できる。   Next, a method of underwater transport of the water blocking lid 2 by the moving device 1 configured as described above will be described. With respect to the water blocking lid 2 installed at a predetermined place in the water, first, the operator remotely operates the moving device 1 while looking at the image of the camera 11, and as shown in FIG. 1 (a), the moving device 1 On the rear side of the water blocking lid 2. Since the aiming unit 12 of the moving device 1 depicted in the case 13 is located on the front side of the camera 11 of the moving device 1, a state in which the cruciform aiming unit 12 is always shown in the image of the camera 11 It is. Then, when the camera 11 is made to face the viewing window 21 of the water blocking lid 2, the cross-shaped aiming portion 22 of the water blocking lid 2 is projected through the viewing window 21. In this state, by adjusting the position and posture of the moving device 1 and overlapping the sighting portion 12 of the moving device 1 and the sighting portion 22 of the water blocking lid 2 through the image of the camera 11, the center axis of the moving device 1 and the stop The central axes of the water lid 2 coincide with each other, and the connecting portion 4 of the moving device 1 and the connected portion 5 of the water blocking lid 2 face in the front-rear direction. Then, when the moving device 1 is advanced from here, the three connecting portions 4 of the moving device 1 are respectively inserted into the insertion holes 61 of the three guide portions 6 of the water blocking lid 2. At this time, even if the sighting part 12 of the moving device 1 and the sighting part 22 of the water blocking lid 2 are somewhat shifted due to the influence of convection etc., the insertion hole 61 of the guide part 6 spreads in a trumpet shape toward the opening side Therefore, the connecting portion 4 is inserted into the insertion hole 61 without any problem. Then, as shown in FIG. 1 (b), when the connecting part 4 abuts on the connected part 5, turning on the power of the connecting part 4 generates a magnetic force, and the connected part 5 is attracted. The water blocking lid 2 is held by the moving device 1 and can be transported in water. On the other hand, in order to separate the moving device 1 from the water blocking lid 2, after the water blocking lid 2 is installed at a predetermined location, the magnetic force disappears by turning off the power of the connecting portion 4. And retract the connecting portion 4 from the insertion hole 61 of the guide portion 6. As described above, when the power of the connecting part 4 is turned on and off, the connecting part 4 is attached to and detached from the connected part 5, and the water blocking lid 2 can be reliably held by the moving device 1 and transported underwater. Also, the moving device 1 can be easily detached from the water blocking lid 2.

また、このように構成した操作機構７及び充水機構８により、止水蓋２を通して充水する方法について、図６に基づき説明する。ここでは、止水蓋２が止水対象となる開口部を塞いでいて、止水蓋２の後側（表側）の空間が水で満たされており、前側（裏側）の空間が排水された状態であるとする。この状態では、充水機構８の弁体８２が、水圧及び付勢部材８６の付勢力により充水口８１に向けて押圧されており、充水口８１が閉じられている。図１（ａ）に示すように、移動装置１の中心軸と止水蓋２の中心軸を一致させると、操作機構７と充水機構８は、前後に対向する（図６（ａ））。ただし、操作機構７の動作部７２のピストンロッド７３は最も後退した位置にあり、操作機構７の係合部７１と充水機構８の被係合部８３は離隔している。この状態から移動装置１を前進させ、図１（ｂ）に示すように、移動装置１の連結部４と止水蓋２の被連結部５を当接させて、止水蓋２が移動装置１に保持された状態にすると、操作機構７の係合部７１の先端が充水機構８の被係合部８３に挿入された配置となる（図６（ｂ））。その後、操作者がコントローラを操作して操作機構７のピストンロッド７３を前進させると、それに伴って係合部７１も前進し、係合部７１の上下に展開した爪部７４が、被係合部８３の突起部８３１に当接し、前進に伴って展開部材７６の付勢力に抗して係合部７１側に折り畳まれて切欠部７５内に納まる（図６（ｃ））。さらに係合部７１を前進させて、爪部７４が被係合部８３の突起部８３１を通過すると、展開部材７６の付勢力により、爪部７４が被係合部８３内で再び外周側に展開する（図６（ｄ））。この状態から、操作機構７の動作部７２のピストンロッド７３を後退させると、それに伴って係合部７１も後退し、さらに係合部７１の爪部７４の先端が被係合部８３の突起部８３１に係止するので、被係合部８３、ロッド８５及び弁体８２も併せて後退する。すると、弁体８２のパッキン８２１が充水口８１の周囲の面から離隔し、内筒体８２２の通水口８２３が被係合部８３内に露出するので、止水蓋２の後側（表側）の空間から、閉止板８４１の流入口８４２及び内筒体８２２の通水口８２３を経由し、止水蓋２の前側（裏側）の空間までが連通して、止水蓋２の充水口８１を通して後側（表側）の空間から前側（裏側）の空間へ充水される（図６（ｅ））。なお、これらの動作は全て止水蓋２が移動装置１に保持された状態、すなわち止水蓋２と移動装置１がともに固定された状態で行われるので、動作部７２の動作により移動装置１自体が動くことはない。   Moreover, the method to charge water through the water blocking lid 2 by the operation mechanism 7 and the water charging mechanism 8 which were comprised in this way is demonstrated based on FIG. Here, the water blocking lid 2 closes the opening for water blocking, the space on the rear side (front side) of the water blocking lid 2 is filled with water, and the space on the front side (back side) is drained. Assume that it is in the state. In this state, the valve body 82 of the water charging mechanism 8 is pressed toward the water charging port 81 by the water pressure and the biasing force of the biasing member 86, and the water charging port 81 is closed. As shown in FIG. 1 (a), when the central axis of the moving device 1 and the central axis of the water blocking lid 2 coincide with each other, the operation mechanism 7 and the water charging mechanism 8 face front to back (FIG. 6 (a)). . However, the piston rod 73 of the operation portion 72 of the operation mechanism 7 is at the most retracted position, and the engagement portion 71 of the operation mechanism 7 and the engaged portion 83 of the water charging mechanism 8 are separated. The moving device 1 is advanced from this state, and the connecting portion 4 of the moving device 1 and the connected portion 5 of the water blocking lid 2 are brought into contact with each other as shown in FIG. In the state of being held at 1, the tip end of the engaging portion 71 of the operation mechanism 7 is disposed so as to be inserted into the engaged portion 83 of the water charging mechanism 8 (FIG. 6 (b)). Thereafter, when the operator operates the controller to move the piston rod 73 of the operation mechanism 7 forward, the engaging portion 71 also advances accordingly, and the claw portions 74 expanded above and below the engaging portion 71 are engaged It abuts on the projecting portion 831 of the portion 83, and is folded toward the engaging portion 71 against the biasing force of the deployment member 76 as it advances, and is accommodated in the notch 75 (FIG. 6C). When the engaging portion 71 is further advanced, and the claw portion 74 passes through the projection 831 of the engaged portion 83, the urging force of the deployment member 76 causes the claw portion 74 to again move outward in the engaged portion 83. Deploy (Fig. 6 (d)). When the piston rod 73 of the operating portion 72 of the operating mechanism 7 is retracted from this state, the engaging portion 71 is also retracted accordingly, and the tip of the claw portion 74 of the engaging portion 71 is further a protrusion of the engaged portion 83 Since it locks to the portion 831, the engaged portion 83, the rod 85 and the valve body 82 are also retracted together. Then, the packing 821 of the valve body 82 is separated from the surface around the water inlet 81, and the water inlet 823 of the inner cylinder 822 is exposed in the engaged portion 83, so the rear side (front side) of the water blocking lid 2 From the space of the closing plate 841 to the space on the front side (back side) of the water blocking lid 2 via the water inlet 842 of the closing plate 841 and the water passing port 823 of the inner cylinder 822. The water is charged from the space on the rear side (front side) to the space on the front side (back side) (FIG. 6 (e)). Note that these operations are all performed in a state where the water blocking lid 2 is held by the moving device 1, that is, in a state in which both the water blocking lid 2 and the moving device 1 are fixed. It does not move itself.

さらに、上記のようにして充水機構８の被係合部８３に操作機構７の係合部７１が係合した状態において、被係合部８３から係合部７１を取り外す方法について、図７に基づき説明する。充水のために充水機構８の充水口８１を開いた状態では、係合部７１の爪部７４の先端が被係合部８３の突起部８３１に係止しており、被係合部８３から係合部７１を取り外すことができない（図７（ａ））。そこでまず、操作機構７の動作部７２のピストンロッド７３とともに係合部７１を前進させて、被係合部８３の突起部８３１から係合部７１の爪部７４を離脱させる（図７（ｂ））。すると、弁体８２は付勢部材８６の付勢力により充水口８１を閉じた状態となる。次に、被係合部８３の上下の貫通孔８７に挿入可能なピン９を有する取外用治具を用意する（図７（ｃ））。次に、取外用治具のピン９を被係合部８３の上下の貫通孔８７に挿入し、爪部７４を内周側に押し込んで、係合部７１の切欠部７５内に納める（図７（ｄ））。そして、取外用治具のピン９を貫通孔８７に挿入したままの状態で、操作機構７の動作部７２のピストンロッド７３とともに係合部７１を後退させれば、爪部７４が被係合部８３の突起部８３１に引っ掛かることはなく、係合部７１が被係合部８３から引き抜かれ、取り外しが完了する（図７（ｅ））。   Furthermore, in the state where the engaging portion 71 of the operation mechanism 7 is engaged with the engaged portion 83 of the water charging mechanism 8 as described above, the method of removing the engaging portion 71 from the engaged portion 83 will be described with reference to FIG. It explains based on. In a state where the water filling port 81 of the water charging mechanism 8 is opened for water filling, the tip end of the claw part 74 of the engaging part 71 is engaged with the projection 831 of the engaged part 83, and the engaged part The engaging part 71 can not be removed from 83 (Fig. 7 (a)). Therefore, first, the engaging portion 71 is advanced with the piston rod 73 of the operating portion 72 of the operating mechanism 7 to separate the claw portion 74 of the engaging portion 71 from the projection 831 of the engaged portion 83 (FIG. 7 (b )). Then, the valve body 82 is in a state in which the water inlet 81 is closed by the biasing force of the biasing member 86. Next, a removal jig having pins 9 insertable into the upper and lower through holes 87 of the engaged portion 83 is prepared (FIG. 7 (c)). Next, the pins 9 of the removal jig are inserted into the upper and lower through holes 87 of the engaged portion 83, and the claws 74 are pushed inward to the inside of the notches 75 of the engaging portion 71 (see FIG. 7 (d). Then, with the pin 9 of the removal jig still inserted into the through hole 87, if the engaging portion 71 is retracted together with the piston rod 73 of the operating portion 72 of the operating mechanism 7, the claw portion 74 is engaged The engaging portion 71 is pulled out of the engaged portion 83 without being caught by the projection 831 of the portion 83, and the removal is completed (FIG. 7 (e)).

このように構成した本発明の充水装置によれば、止水蓋２をダム湖１０から配管２０などの止水対象となる開口部に設置し、止水蓋２の前側（裏側）から排水することで、後側（表側）と前側（裏側）の水圧差により、止水蓋２が押圧されて固定されるとともに、弁体８２が押圧されて充水口８１を閉じる。そして、操作機構７により弁体８２を動かして充水口８１を開けば、止水蓋２を通して後側（表側）から前側（裏側）に充水することができる。そして、付勢部材８６が弁体８２を充水口８１に向けて押圧するので、水深が浅い場合など、止水蓋２の後側（表側）と前側（裏側）の水圧差が十分でない場合でも、確実に充水口８１を閉じることができ、外的要因によって充水口８１が開くことがない。さらに、操作機構７の動作部７２により係合部７１を充水機構８側へ移動させるだけで、係合部７１の爪部７４が被係合部８３の突起部８３１に係止するので、容易かつ確実に係合部７１が被係合部８３に係合して、弁体８２を動かすことができる。また、止水蓋２の前側（裏側）から排水するとき及び止水蓋２を通して前側（裏側）に充水するときに、止水蓋２の覗き窓２１を通して排水又は充水の状況をカメラ１１の画像で視認できる。さらに、止水蓋２によりダム湖１０に連通する配管２０を塞ぐ際、止水蓋２の周縁部が配管２０の開口部の周囲の面に当接するが、止水蓋２の最外周部の前側面には、全周にわたって高弾性スポンジゴムからなる止水部２６を取り付けてあり、この止水部２６には水深に応じた圧縮変形が生じるので、当接面に凹凸があっても、止水部２６が凹凸に沿って変形し、確実に止水される。   According to the water storage device of the present invention configured as described above, the water blocking lid 2 is installed from the dam lake 10 to the opening to be a water blocking object such as the piping 20, and drainage is performed from the front side (back side) of the water blocking lid 2. By doing so, the water blocking lid 2 is pressed and fixed by the water pressure difference between the rear side (front side) and the front side (back side), and the valve body 82 is pressed to close the water charging port 81. Then, when the valve body 82 is moved by the operation mechanism 7 to open the water filling port 81, water can be charged from the rear side (front side) to the front side (back side) through the water blocking lid 2. And since the biasing member 86 presses the valve body 82 toward the water filling port 81, even when the water depth is shallow, even if the water pressure difference between the back side (front side) and the front side (back side) of the water blocking lid 2 is not sufficient. The charging port 81 can be reliably closed, and the charging port 81 does not open due to an external factor. Furthermore, the claw portion 74 of the engagement portion 71 is engaged with the projection 831 of the engaged portion 83 only by moving the engagement portion 71 toward the water charging mechanism 8 by the operation portion 72 of the operation mechanism 7. The engaging portion 71 can be engaged with the engaged portion 83 easily and reliably, and the valve body 82 can be moved. In addition, when draining from the front side (back side) of the water blocking lid 2 and when water is filled to the front side (back side) through the water blocking lid 2, the status of the drainage or water filling through the viewing window 21 of the water blocking lid 2 is camera 11 It can be seen in the image of. Furthermore, when closing the pipe 20 communicating with the dam lake 10 with the water blocking lid 2, the peripheral portion of the water blocking lid 2 abuts on the surface around the opening of the pipe 20. On the front side, the water blocking portion 26 made of high elastic sponge rubber is attached over the entire circumference, and the water blocking portion 26 is subjected to compressive deformation corresponding to the water depth, so even if the contact surface has unevenness, The water blocking portion 26 is deformed along the asperities, and the water blocking is surely performed.

また、着脱機構３の連結部４が電磁石からなり、被連結部５が磁性体である鋼鉄からなるので、連結部４の電源をオンにすると、連結部４の磁力により被連結部５が吸着されて、移動装置１により止水蓋２が確実に保持される。そして、連結部４の電源のオンオフにより、磁力が瞬時に発生・消滅するので、移動装置１により止水蓋２を容易に着脱できる。また、連結部４が被連結部５に設けたガイド部６の挿入穴６１に挿入される構造なので、移動装置１に対して止水蓋２が正確に位置決めされる。水中搬送に際しては、移動装置１が止水蓋２を正しい位置で保持しないと、浮力のバランスが崩れて移動装置１が正しい姿勢を維持できず、スムーズに搬送できないおそれがあるが、本構造により、確実に正しい位置で保持できる。さらに、連結部４をガイド部６の挿入穴６１に挿入する際に、相互の位置が多少ずれていても、連結部４が挿入穴６１の内周面にガイドされてスムーズに挿入されるので、より容易に位置決めできる。また、移動装置１のカメラ１１の前側に止水蓋２が保持されるが、止水蓋２の覗き窓２１を通して止水蓋２の前側を撮影可能なので、支障なく遠隔操作できる。そして、操作者が、カメラ１１の画像を通して移動装置１の照準部１２と止水蓋２の照準部２２が重なり合うように移動装置１を操作することで、被連結部５に対して連結部４が位置決めされるので、そのまま移動装置１を前進させれば連結部４が被連結部５に当接するものであり、操作が容易である。   Further, since the connecting portion 4 of the mounting and demounting mechanism 3 is an electromagnet and the connected portion 5 is made of steel which is a magnetic body, when the power of the connecting portion 4 is turned on, the magnetic force of the connected portion 4 is attracted by the magnetic force of the connecting portion 4 As a result, the water blocking lid 2 is reliably held by the moving device 1. And since the magnetic force is generated and disappears instantaneously by turning on and off the power supply of the connecting part 4, the water blocking lid 2 can be easily attached and detached by the moving device 1. Further, since the connecting portion 4 is inserted into the insertion hole 61 of the guide portion 6 provided in the connected portion 5, the water blocking lid 2 is accurately positioned with respect to the moving device 1. If the moving device 1 does not hold the water blocking lid 2 at the correct position during underwater conveyance, the balance of buoyancy is lost and the moving device 1 can not maintain the correct posture, and there is a risk that smooth conveyance can not be achieved. It can be held securely in the correct position. Furthermore, when inserting the connecting portion 4 into the insertion hole 61 of the guide portion 6, the connecting portion 4 is guided by the inner peripheral surface of the insertion hole 61 and smoothly inserted even if the mutual positions are slightly deviated. It can be positioned more easily. Further, although the water blocking lid 2 is held on the front side of the camera 11 of the moving device 1, since the front side of the water blocking lid 2 can be photographed through the observation window 21 of the water blocking lid 2, remote control can be performed without any problem. Then, the operator operates the moving device 1 so that the sighting portion 12 of the moving device 1 and the sighting portion 22 of the water blocking lid 2 overlap with each other through the image of the camera 11. As the moving device 1 is advanced as it is, the connecting portion 4 abuts on the connected portion 5 and the operation is easy.

本発明は、上記の実施形態に限定されない。たとえば、上記実施形態では、移動装置の中心軸と止水蓋の中心軸を一致させているが、これは必ずしも一致させなくてもよく、止水蓋を保持した状態で、移動装置に設けた操作機構の係合部と止水蓋に設けた充水機構の被係合部の中心軸が一致すればよい。また、係合部と被係合部に構造は、相互に係合して弁体を操作可能となるものであればどのようなものであってもよく、その構造によっては、両者の中心軸を一致させなくてもよい場合もあり得る。さらに、充水機構の被係合部をマニュアルハンドルとし、操作機構の係合部をマニピュレータなどの把持部として、遠隔操作で把持部によりハンドルを把持して充水口を開閉するものであってもよい。   The present invention is not limited to the above embodiments. For example, in the above embodiment, the central axis of the moving device and the central axis of the water blocking lid are made to coincide with each other, but this does not have to be necessarily the same. It suffices that the central axes of the engaging portion of the operation mechanism and the engaged portion of the water charging mechanism provided on the water blocking lid coincide with each other. Further, the structure of the engaging portion and the engaged portion may be anything as long as the valve body can be operated by engaging with each other, and depending on the structure, the central axes of both may be used. There is a possibility that they do not have to match. Furthermore, even if the engaged portion of the water charging mechanism is a manual handle and the engaging portion of the operation mechanism is a gripping portion of a manipulator or the like, the handle is gripped by the gripping portion by remote control to open and close the water charging port. Good.
