Description

  The present invention relates to an antifouling panel member and a structure on which the antifouling panel member is installed. In particular, the antifouling panel is attached to a wall surface in contact with seawater and generates oxygen by electrolysis of the seawater to prevent adhesion of marine organisms. The present invention relates to an antifouling panel member and a structure on which the antifouling panel member is installed.

  Marine organisms such as mussels and barnacles adhere to the wall surface of the structure in contact with seawater, but such adhesion of marine organisms may be a problem. For example, power plants use seawater as cooling water, but if marine organisms adhere to the waterway (seawater channel) for drawing in seawater, the water intake flow rate may decrease, causing normal functions of the seawater channel. Will be disturbed. Therefore, many techniques have been proposed in order to prevent marine organisms from adhering to the wall surface in contact with seawater. Among them, as a technology to prevent the attachment of marine organisms without generating harmful substances, the organic material is decomposed by generating oxygen by electrolyzing the seawater using an anode sheet attached to the wall in contact with the seawater. Therefore, the technology that prevents the attachment of marine organisms is considered promising. An example of such a technique is disclosed in Patent Document 1.

Patent Document 1 discloses a marine organism in which an anode forming plate (anode sheet) is mounted on the surface of an insulating material, and a plurality of cathode forming strips extending in the flow direction of the intake channel are mounted on the back side of the insulating material. A marine organism adhesion prevention device is disclosed in which an adhesion prevention plate is disposed on the inner wall surface of a water channel, and an anode-forming plate-like body and a cathode-forming belt-like body are electrically joined to an external DC power source. In the technique of Patent Document 1, the marine organism adhesion prevention plate is composed of a plurality of composite plates (antifouling panel members). Each of these composite plates includes a panel-like titanium plate comprising a main body part, an upper overlapping part and a lower overlapping part, an insulating material disposed on the back surface of the main body part and the lower overlapping part of the panel-like titanium plate, It consists of a long stainless steel plate arrange | positioned through the insulating material at the end of the titanium plate. The long stainless steel plate has a protruding portion protruding from the lower overlapping portion of the panel-like titanium plate, and the insulating material is an insulating resin arranged in the fixed portion and a foam arranged in the other portion. It consists of materials.
Japanese Patent No. 4256319 [A01M 29/00]

  In the technique of Patent Document 1, the composite plate is fixed to the inner wall surface of the intake channel by driving anchor bolts to both ends of the fixed portion of the composite plate in a state where the upper and lower overlapping portions of the panel-like titanium plate are overlapped. The electrical conductivity between adjacent panel-like titanium plates (and thus the whole anode sheet) is to be secured. However, in the technique of Patent Document 1, since only the both side ends of the overlapping portion of the panel-like titanium plate are pressed by the anchor bolts, floating or gaps are easily generated in the overlapping portion between the anchor bolts. , There is a risk that stable current conduction cannot be ensured. For example, if the panel-like titanium plate is bent due to construction failure or the like, and the upper and lower overlapping portions are not firmly overlapped with each other, it is not possible to secure stable electrical conductivity. For this reason, in actual construction, it may be necessary to spot weld the upper and lower overlapping portions in order to ensure stable electrical conductivity. Furthermore, since the titanium bar is tightened with bolts and nuts using a conductive titanium bar to connect the titanium plates to each other, the tightening may be loosened after a long period of time. In this case, the surface contact between the overlapping portions of the panel titanium plate cannot be properly maintained.

  Therefore, in the technique of Patent Document 1, appropriate surface contact between the upper and lower overlapping portions of the panel-like titanium plate cannot be maintained for a long period, that is, the conductivity of the anode sheet is stable for a long period. May not be maintained.

  Therefore, a main object of the present invention is to provide a novel antifouling panel member and a structure in which the antifouling panel member is installed.

  As shown in FIG. 6, first, a cathode-side conductor (cathode-side wiring) 50 formed of a stainless steel strip or the like is installed in the tube axis direction of the seawater channel 102, and then the seawater channel 102. A start member 52 is attached to the bottom surface. The start member 52 is obtained by cutting only the portion on the one end 26 side including the recessed portion 30 from the substrate 20 described above. When attaching the start member 52, first, an embedded anchor 54 (see FIG. 8) is installed at the attachment position of the start member 52. Then, the start member 52 is fixed to the bottom surface of the seawater channel 102 by attaching a bolt 56 to the embedded anchor 54 through each through hole formed in the start member 52. In addition, when attaching the start member 52 and the panel member 10 subsequent thereto to each wall surface of the seawater channel 102, the start member 52 and the panel member 10 may be attached via spacers 58 (see FIG. 8) formed of rubber or the like. For example, when the filler is injected between each wall surface of the seawater channel 102 and the antifouling panel 12, the spacer 58 secures a space as a path for the filler.

  Subsequently, in the same manner as the connecting method shown in FIG. 5, the panel member 10 is connected to the start member 52, and the bottom wall of the recess 30 of the panel member 10 is anchored by the embedded anchor 54 and the bolt 56. The panel member 10 is fixed to the bottom surface of the seawater channel 102. Then, as shown in FIG. 7, the antifouling panel 12 is formed over the whole construction part by connecting and fixing the panel member 10 sequentially. At this time, as shown in FIG. 8, the heads of the bolts 56 are accommodated in a space formed by the recessed part 30 of the panel member 10 and the part on the other end 28 side of the flat plate part 24. That is, since the anchoring bolts 56 do not protrude from the surface of the panel member 10, the antifouling panel 12 having a smooth surface is formed. Further, as described above, by simply connecting the panel members 10 to each other, the adjacent titanium sheet elements 22 are connected to each other so as to be energized, and the titanium sheet 14 covering the entire surface of the antifouling panel 12 is formed.

  Further, when the antifouling panel 12 is formed, a cathode bar (cathode member) 60 formed in a rod shape with stainless steel or the like is installed at a ratio of about one for the two panel members 10. In this embodiment, the cathode bar 60 is installed using a recess 30 and a bolt 56 made of stainless steel for anchoring. That is, as shown in FIG. 9A, a screw hole 62 is formed in advance on the head of the bolt 56 at the position where the cathode bar 60 is to be installed, and the flat plate portion 24 covering the top thereof. A through hole 64 is formed in advance. Further, when the panel member 10 is anchored, a cathode-side conductor 50 formed of a stainless steel strip or the like is installed at the same time (see FIG. 2). The cathode-side conductor 50 is connected to the cathode-side conductor 50 that has been previously installed in the tube axis direction of the seawater channel 102. Then, as shown in FIG. 9B, the cathode bar 60 is installed using the screw holes 62 of the bolts 56 at an appropriate time after the panel member 10 (antifouling panel 12) is attached. At this time, the tip of the cathode bar 60 protrudes about several cm from the surface of the panel member 10 so that seawater can be efficiently electrolyzed. However, the cathode bar 60 is not necessarily required to protrude from the surface of the panel member 10 and is not necessarily provided.

  When the panel member 10 (antifouling panel 12) is attached to the bottom surface of the sea channel 102, the panel member 10 is attached to the side surface and the top surface of the sea channel 102 in the same manner. Thereafter, if necessary, a filler such as mortar is injected between each wall surface of the seawater channel 102 and the antifouling panel 12 to firmly integrate each wall surface of the seawater channel 102 and the antifouling panel 12. The titanium sheet 12 formed on the surface of the antifouling panel 12 is connected to the positive electrode of the DC power supply device 16 installed outside, and the negative electrode of the DC power supply device 16 is connected to the cathode-side conductor 50. .

  According to this embodiment, since the titanium sheet element 22 is affixed to the substrate 20 so as to extend to the fitting portions (the engaging portion 32 and the receiving portion 38), the adjacent titanium can be obtained by fitting the fitting portions. The end portions of the sheet element 22 are uniformly pressed by the substrate 20 to come into surface contact. Therefore, the electrical conductivity between the adjacent titanium sheet elements 22 (and thus the titanium sheet 14) is stably ensured over a long period of time. In addition, since it is not necessary to perform spot welding in order to ensure stable electrical conductivity between the adjacent titanium sheet elements 22, attachment work is facilitated and the number of construction steps is reduced, thereby reducing costs. it can.

  Moreover, since the head of the bolt 56 used for anchoring does not protrude from the surface of the formed antifouling panel 12, obstruction of the flow of water after construction is reduced and the landscape is also improved.

  Next, with reference to FIGS. 10-13, the structure of the panel member 10 which is the other Example of this invention is demonstrated. The panel member 10 shown in FIG. 10 forms a groove portion with respect to the flat plate portion 24 of the panel member 10 shown in FIG. 3, and a lid is attached to the groove portion. Since the basic configuration of the other portions is substantially the same as that of the panel member 10 shown in FIG. 3, the same reference numerals are given to the common portions, and redundant descriptions are omitted or simplified.

  As shown in FIGS. 10 to 13, the panel member 10 of this embodiment includes a member main body 70 and a lid 72. The member main body 70 is substantially the same as the panel member 10 shown in FIG. 3, but the substrate 20 of the member main body 70 has a groove portion that functions as a second recess portion in addition to the recess portion 30 that functions as a first recess portion. 74 is formed with respect to the flat plate portion 24. The groove portion 74 is formed in a substantially U shape that extends over the entire length in the width direction of the flat plate portion 24 at an arbitrary position between the one end 26 and the other end 28 and is recessed from the flat plate portion 24. An engaging portion 76 is formed on each inner surface of the side wall of the groove portion 74. Further, the titanium sheet element 22 attached to the member main body 70 is divided into two. One of them is affixed to the substrate 20 so as to cover the entire surface of the flat plate portion 24 on the one end 26 side and extend to the upper surface of the engaging portion 32 and the upper surface of the engaging portion 76. The other one is attached to the substrate 20 so as to cover the entire surface of the flat plate portion 24 on the other end 28 side and to extend to the inner surface of the receiving portion 28 and the upper surface of the engaging portion 76.

  The lid 72 covers the entire upper portion of the groove portion 74 of the member main body 70 and maintains the smoothness and electrical conductivity of the surface of the panel member 10. The lid 72 includes a rectangular flat plate-like portion 78. Two protrusions that rise in an oblique direction are formed on the back surface of the plate-shaped portion 78, and these protrusions and the end of the plate-shaped portion 78 are integrated to form two locking portions that open in the lateral direction. 80 is formed. Further, the titanium sheet element 22 is affixed to the surface of the plate-like portion 78, and the end portion of the titanium sheet element 22 extends to the back surface of the end portion in the connecting direction of the plate-like portion 78, that is, the locking portion 80.

  As shown in FIG. 13, when the lid 72 is attached to the member main body 70, the engaging portion 76 of the member main body 70 and the locking portion 80 of the lid 72 are fitted and fixed. Then, the two titanium sheet elements 22 of the member main body 70 and the titanium sheet element 22 of the lid 72 are brought into surface contact so that the ends thereof are pressed against each other. As a result, the electrical conductivity of the titanium sheet element 22 covering the surface of the panel member 10 as a whole is stably secured.

  When attaching the panel member 10 shown in FIG. 10 to the sea channel 102, the member main body 70 is fixed to the wall surface of the sea channel 102 in the same manner as the panel member 10 shown in FIG. That is, the upper part of the hollow part 30 is covered with the portion on the other end 28 side of the flat plate part 24, and the engaging part 32 and the receiving part 38 of the adjacent member main body 70 are fitted and connected to each other. At anchoring. The lid 72 may be attached at an appropriate time.

  Similarly, in the panel member 10 shown in FIG. 10, the ends of the adjacent titanium sheet elements 22 are evenly pressed and brought into surface contact by the fitting of the engaging portions 32 and the receiving portions 38 of the adjacent panel members 10. Therefore, the electrical conductivity between the adjacent titanium sheet elements 22 (and thus the titanium sheet 14) is stably ensured over a long period of time. Moreover, since the head of the bolt 56 used for anchoring does not protrude from the surface of the formed antifouling panel 12, obstruction of the flow of water after construction is reduced and the landscape is also improved.

  However, the panel member 10 shown in FIG. 10 is different from the panel member 10 shown in FIG. 3 in the way of installing the cathode-side conductor 50 and the cathode bar 60. That is, in the panel member 10 shown in FIG. 10, as shown in FIGS. 14 and 15, the cathode-side conductor 50 and the cathode bar 60 are installed using the groove 74 of the member main body 70. For example, a through hole 82 for allowing the cathode bar 60 to protrude is formed in the lid 72. In addition, the rod-shaped cathode bar 60 is provided with a flange portion 84 for holding the cathode-side conductor 50 and a male screw 86 formed at the lower portion. Then, the cathode bar 60 may be fixed to the groove portion 74 by using the flange portion 84 and the nut 88 attached to the male screw 86 so as to sandwich the cathode-side conductor 50 disposed in the groove portion 74 and the bottom portion of the groove portion 74. However, the shape and fixing method of the cathode bar 60 are not limited to this. For example, a male screw may be formed in the lower part of the cathode bar 60, and the cathode bar 60 may be fixed to the groove portion 74 by being sandwiched between two nuts. Further, for example, a screw hole (hole) may be formed in the bottom wall itself of the groove portion 74, and the cathode bar 60 may be fixed to the groove portion 74 using the screw hole.

  The cathode-side conductor 50 and the cathode bar 60 may be installed in the groove 74 either before, when, or after the member main body 70 is attached to the seawater channel 102. For example, the cathode bar 60 is fixed to the groove portion 74 in advance, and after the plurality of member main bodies 70 are attached to the seawater channel 102, the cathode-side conductor 50 passing through the groove portion 74 is connected to the cathode bar 60. Also good. Further, for example, both the cathode-side conductor 50 and the cathode bar 60 may be fixed in advance in the groove 74 and the member main body 70 may be attached to the seawater channel 102. Further, for example, the cathode-side conductor 50 and the cathode bar 60 may be fixed to the groove 74 after the plurality of member main bodies 70 are attached to the seawater channel 102.

  As described above, according to the panel member 10 shown in FIG. 10, the cathode-side conductor 50 and the cathode bar 60 can be installed using the groove portion 74 of the member main body 70. In this case, since the cathode-side conductor 50 can be installed after the plurality of member main bodies 70 (antifouling panels 12) are attached to the seawater channel 102, the degree of freedom in construction increases and the construction becomes easy. .

  In addition, although the panel member 10 shown in FIG. 10 can also be used independently, it can also be used in combination with the panel member 10 shown in FIG. As described above, since the cathode bar 60 is installed at a ratio of about one to the two panel members 10, for example, the panel members 10 shown in FIG. 3 and the panel members 10 shown in FIG. The cathode-side conductor 50 and the cathode bar 60 are preferably installed by using the groove 74 of the panel member 10 shown in FIG.

  In each of the above-described embodiments, the anchoring is performed at the recessed portion 30 formed at the one end 26 of the flat plate portion 24, but the fixing method of the panel member 10 is not limited to this. Further, the fitting structure of the fitting portion (the engaging portion 32 and the receiving portion 38 in the embodiment shown in FIGS. 3 and 10) formed at the one end 26 and the other end 28 of the flat plate portion 24 is not limited to this. .

  For example, as in the embodiment shown in FIG. 16, an insertion portion (first fitting portion) 90 extending in the lateral direction from the back surface is formed at one end of the flat plate portion 24, and the other end of the flat plate portion 24 is A substantially U-shaped receiving portion (second fitting portion) 92 is formed integrally with the end portion of the flat plate portion 24 and opens sideways. Then, by fitting the insertion portion 90 and the receiving portion 92, the ends of the adjacent titanium sheet elements 22 can be brought into surface contact with each other so as to be energized. In this case, when the panel member 10 is fixed to the seawater channel 102 by anchoring at an appropriate position of the flat plate portion 24, the cathode-side conductor 50 is installed so as to pass through the space on the back surface side of the flat plate portion 24. Good.

  Further, for example, as in the embodiment shown in FIG. 17, a saw blade-like protrusion (first fitting portion) 94 is formed on one end face of the flat plate portion 24, and the other end face of the flat plate portion 24 is formed. Corresponding receiving portions (second fitting portions) 96 are formed. Then, by fitting the projecting portion 94 and the receiving portion 96, the ends of the adjacent titanium sheet elements 22 can be brought into surface contact with each other so as to be energized. In this case, for example, a groove 98 may be formed on the back surface side of the flat plate portion 24, and the cathode-side conductor 50 may be installed so as to pass through the groove 98. Further, the panel member 10 may be fixed to the seawater channel 102 by anchoring at an appropriate position of the flat plate portion 24.

  Although illustration is omitted, also in the panel member 10 having a fitting structure as shown in FIGS. 16 and 17, the groove portion 74 is formed in the flat plate portion 24 as in the panel member 10 shown in FIG. 10. The groove 74 may be covered with a lid 72. In this case, the groove portion 74 functions as a first recess portion, and the groove portion 74 can be used for installing the cathode-side conductor 50 and the cathode bar 60 and for anchoring. Alternatively, two rows of groove portions 74 may be formed on the flat plate portion 24, and the lid 72 may be attached to each of the two rows of groove portions 74. In this case, for example, one groove 74 can be used for anchoring, and the other groove 74 can be used for installing the cathode-side conductor 50 and the cathode bar 60. That is, one groove portion 74 functions as a first recess portion, and the other groove portion 74 functions as a second recess portion.

  In each of the above-described embodiments, the dent 30 and the groove 74 (the first dent and the second dent) are formed over the entire length in the width direction of the substrate 20, but the present invention is not limited thereto. It can also be formed partially in the width direction.

  Further, in each of the above-described embodiments, the ends of the adjacent titanium sheet elements 22 are brought into surface contact with each other by fitting of the fitting portions so as to be electrically connected. You may make it apply | coat an electrically conductive adhesive with respect to the edge part surface (namely, contact part). As a result, the ends of the adjacent titanium sheet elements 22 are more firmly connected to each other and are more resistant to corrosion, so that the conductivity of the titanium sheet 14 can be reliably maintained over a longer period. This also applies to the case where the upper portion of the groove portion 74 is covered with the lid 72, and an electroconductive adhesive may be applied to the end surface of the titanium sheet element 22.

  Further, in each of the above-described embodiments, the ends of the adjacent titanium sheet elements 22 are fitted by fitting the first fitting portion and the second fitting portion (such as the engaging portion 32 and the receiving portion 38) of the substrate 20. The parts are energized, but the present invention is not limited to this, and the ends of the titanium sheet elements of the adjacent panel members 10 are energized through the lid as in the panel member 10 shown in FIGS. You can also

  Hereinafter, with reference to FIGS. 18-21, the structure of the panel member 10 which is the other Example of this invention is demonstrated. The panel member 10 shown in FIG. 18 is basically the same as the panel member 10 shown in FIG. 3 and FIG. 10 except for the portions other than energizing the ends of the titanium sheet elements of the adjacent panel members 10 through the lid. Since the configuration and the operation and effect are common, overlapping description will be omitted or simplified.

  As shown in FIG. 18, the panel member 10 of this embodiment includes a member main body 110 and a lid 112. Further, as shown in FIG. 19, the member main body 110 includes a substrate 114 formed of an insulating material and a titanium sheet element 116 attached thereto.

  The substrate 114 includes a flat plate portion 120 formed in a flat plate shape. One end (first end) 122 and the other end (second end) 124 in the connecting direction of the flat plate portion 120 extend in a straight line with respect to the width direction in parallel to each other. In each of the one end 122 and the other end 124 of the flat plate portion 120, recessed portions 126 and 128 are formed over the entire length in the width direction.

  A depression (first depression) 126 formed at one end 122 has a substantially J-shaped cross-sectional shape, and extends from the back surface side of one end 122 of the flat plate portion 120 toward the opposite direction of the other end 124. It protrudes and its tip portion curves upward. However, the shape of the dent portion 126 (the same applies to the dent portion 128 described later) is not limited to this, and may be formed in a shape (substantially L-shaped) in which the tip portion is not curved upward, for example. A receiving portion (first fitting portion) 130 is formed at the tip of the recessed portion 126 over the entire length in the width direction. The receiving part 130 is formed so as to have a substantially U-shaped cross-sectional shape that is integrated with the tip part of the recessed part 126 and opens sideways. In addition, a plurality of through holes 132 are provided in the bottom wall of the recessed portion 126 at predetermined intervals in the width direction. The through hole 132 is used when the panel member 10 is anchored to the wall surface of the seawater channel 102. Furthermore, the engaging part 134 which has a substantially triangular cross-sectional shape is formed in the base part of the hollow part 126 over the full length of the width direction.

  On the other hand, the dent part (second dent part) 128 formed in the other end 124 has a substantially J-shaped cross-sectional shape, and extends in the direction opposite to the one end 122 from the back surface side of the one end 124 of the flat plate part 120. Projecting toward the top, the tip portion is curved upward. An engaging portion (second fitting portion) 136 that fits with the receiving portion 130 is formed at the tip of the hollow portion 128. The engaging portion 136 is formed so as to extend in the direction opposite to the one end 122 from the tip of the recess 128. The receiving portion 130 and the engaging portion 136 are mainly used for positioning when the panel members 10 are connected to each other. Therefore, the receiving portion 130 and the engaging portion 136 do not need to be closely fitted to each other, and the fitting structure is not particularly limited. . For example, the receiving part 130 and the engaging part 136 may be in contact with each other. An engaging portion 138 having a substantially triangular cross-sectional shape is formed at the base portion of the recess portion 128 over the entire length in the width direction.

  In addition, the titanium sheet element 116 is attached to the substrate 114 so as to cover the entire surface of the flat plate portion 120 and extend to the upper surfaces of the engaging portions 134 and 138. That is, the titanium sheet element 116 not only covers the entire surface of the flat plate portion 120 but also a flat plate that is a portion that presses when the engaging portions 134 and 138 and a locking portion 142 of the lid 112 described later are fitted. It is affixed on the board | substrate 114 so that the whole end surface of the one end 122 and the other end 124 of the part 120 and the whole upper surface of the engaging part 134,138 may also be covered.

  The lid 112 covers the entire upper portions of the recess portions 126 and 128 after connecting the member main bodies 110 to each other, and maintains the smoothness and electrical conductivity of the surface of the formed antifouling panel 12. As shown in FIG. 20, the lid 112 includes a rectangular flat plate-like portion 140. Two protrusions rising in an oblique direction are formed on the back surface of the plate-like portion 140, and these protrusions and the end of the plate-like portion 140 are integrated to form two locking portions that open in the lateral direction. 142 is formed. Further, a titanium sheet element 144 is attached to the surface of the plate-like portion 140, and an end portion of the titanium sheet element 144 extends to the back surface of the end portion in the connecting direction of the plate-like portion 140, that is, the locking portion 142. Further, the lid 112 is appropriately formed with a through hole (not shown) for projecting the cathode bar.

  When the panel members 10 shown in FIG. 18 are connected to each other and attached to the sea channel, first, the member main bodies 110 are sequentially connected and fixed as shown in FIG. That is, after the preceding member main body 110 is fixed to the seawater passage, the subsequent member main body 110 is positioned by fitting the receiving portion 130 and the engaging portion 136 of the adjacent member main body 110 together. And in the state which positioned, the subsequent member main body 110 is anchored using the through-hole 132 of the hollow part 126. FIG. In this case, the cathode-side conductor and the cathode bar may be appropriately installed using the recess 128. However, the depression 126 can be used for installing the cathode-side conductor and the cathode bar, and the depression 128 can be used for anchoring.

  Then, as shown in FIG. 21 (B), a lid 112 is attached to the connected member main body 110 at an appropriate time after the anchor stop and the installation of the cathode-side conductor and the cathode bar. That is, the engaging portions 134 and 138 of the member main body 110 and the locking portion 142 of the lid 112 are fitted and fixed so as to cover the upper portions of the recessed portions 126 and 128 of the adjacent member main bodies 110. At this time, the adjacent titanium sheet elements 116 and 144 are uniformly pressed against each other by the rigid substrate 114 and the plate-like portion 140 and are in surface contact with each other, so that the adjacent titanium sheet elements 116 and 144 are in contact with each other ( As a result, the conductivity of the titanium sheet 14) is stably secured. In addition, if an electroconductive adhesive is apply | coated with respect to the edge part surface of the titanium sheet element 116,144, electroconductivity can be ensured more stably.

  As described above, according to the panel member 10 shown in FIG. 18, only by attaching the lid 112 to the connected member main body 110, the end of the titanium sheet element 144 of the lid 112 and the titanium sheet element of the adjacent member main body 110. Each of the ends of 116 is connected to be energized. In addition, since the entire end portions of the titanium sheet elements 116 and 144 are uniformly pressed by the substrate 114 and the plate-like portion 140 to come into surface contact, the formed titanium sheet 14 is stably conductive over a long period of time. Can be secured. Moreover, according to the panel member 10 shown in FIG. 18, since a cathode side conductor etc. can also be installed after attaching the several member main body 110 to a seawater channel, the freedom degree of construction increases and construction is also easy. Become.

  In each of the above-described embodiments, the antifouling panel 12 is formed by connecting the panel member 10 in the pipe axis direction (flowing water direction) of the seawater channel 102, but the panel member 10 is disposed in the circumferential direction of the seawater channel 102. Can also be connected. Further, the panel member 10 (antifouling system 100) may be applied anywhere as long as it is in contact with seawater. For example, the panel member 10 (antifouling system 100) may be applied to a grooved seawater channel (open water channel) whose upper part is open. It can also be applied to piers and coastal walls. Furthermore, if the wall surface to apply is a curved surface, the panel member 10 can also be formed in the curved plate shape corresponding to the curvature.

  Further, in each of the above-described embodiments, titanium is used as the material of the anode sheet element 22 (anode sheet 14), and stainless steel is used as the material of the cathode-side conductor 50 and the cathode bar 60. As long as oxygen can be generated, these materials may be appropriately changed. However, it preferably has resistance to corrosion.
