  The adhesion of marine organisms such as mussels and barnacles to the wall surface of structures in contact with seawater 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 producing harmful substances, seawater is electrolyzed using an anode attached to the wall in contact with seawater to generate oxygen and decompose organic matter. 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-like body (anode body) is attached to the surface of an insulating material, and a plurality of cathode-forming belt-like bodies extending in the flow direction of the intake channel are attached to the back surface side of the insulating material. An apparatus for preventing adhesion of marine organisms is disclosed, in which an adhesion prevention plate (antifouling panel) is disposed on the inner wall surface of a water channel, and an anode forming plate-like body and a cathode forming strip-like body are electrically joined to an external DC power source. Yes. In the technique of Patent Literature 1, the marine organism adhesion prevention plate is constituted by a plurality of composite plates (panel members). Each of these composite plates has a panel-like titanium plate (anode element) composed of a main body part, an upper overlapping part and a lower overlapping part, and an insulation disposed on the back surface of the main body part and the lower overlapping part of the panel-like titanium plate. And a long stainless steel plate disposed at one end of the panel-like titanium plate via an insulating material. 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 arranged on the insulating resin arranged on the fixture mounting portion and other portions. Made of foam material.

  1-3, a panel mounting member (hereinafter simply referred to as “mounting member”) 10 according to one embodiment of the present invention is a marine organism such as a mussel or a barnacle on a wall surface of a structure in contact with seawater. Is used in the antifouling system 100 for preventing the adhesion of water. In this embodiment, an example in which the antifouling system 100 (attachment member 10) is applied to a concrete box culvert type seawater channel 102 is shown.

  In the antifouling system 100, the antifouling panel 12 is attached to each of the bottom surface, the side surface, and the top surface of the seawater channel 102, and the attachment member 10 is provided on each end (four sides) of the antifouling panel 12. Then, the anode body 14 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 is connected to the mounting member 10 to allow weak electricity to flow. Thus, the seawater is electrolyzed to generate oxygen from the anode body 14. The generated oxygen decomposes organic matter that is a nutrient of bacteria. Therefore, the antifouling system 100 can suppress the growth of bacteria, and the formation of a slime layer due to the growth of bacteria, the accompanying adhesion of algae and marine organisms. Can be prevented. In this antifouling system 100, the antifouling panel 12 is formed by connecting a plurality of panel members 18.

  First, the configuration of the panel member 18 will be described with reference to FIGS. 4 and 5. However, the panel member 18 described below is merely an example, and the attachment member 10 is not limited to the panel member 18 and is attached to an end portion of a panel member (antifouling panel) having another configuration. Can be used.

  As shown in FIGS. 4 and 5, the panel member 18 includes a substrate 20 and an anode element 22 attached thereto, and is connected to, for example, the pipe axis direction (flowing water direction) of the seawater channel 102 to form the antifouling panel 12. To do. Moreover, the anode element 14 is formed by connecting the anode elements 22 so as to be energized.

  The length of the connection direction of the panel member 18 is 800 mm, for example, and the length of the width direction is 2000 mm, for example. The size of the panel member 18 is the largest in a range that does not hinder the construction work when the seawater channel 102 is in use, that is, antifouling work in seawater is required and improvement in construction speed is required. This is what you set. That is, the length in the connecting direction is the maximum length that can be carried in from the inspection manhole (standard is 900φ). The length in the width direction is the maximum length that can be transported underwater without any trouble by the worker (diver) as a result of the workability experiment. Moreover, the weight of the panel member 18 is 15 kg, for example.

  The substrate 20 is formed of an insulating material, for example, a synthetic resin such as a vinyl chloride resin or a polyolefin resin. The substrate 20 includes a main body 24 formed in a rectangular flat plate shape. A first fitting portion 26 is formed at the lower end of one end of the connecting direction of the main body 24. Further, a second fitting portion 28 is formed on the other end upper portion of the main body 24 in the connecting direction. The first fitting portion 26 and the second fitting portion 28 have a rectangular cross-sectional shape protruding from the end portion of the main body 24, and are formed over the entire length of the main body 24 in the width direction. In this embodiment, the thickness of the main body 24 is 10 mm. Moreover, the thickness of the 1st fitting part 26 and the 2nd fitting part 28 is 4.7 mm, and the protrusion length is 19.7 mm. The panel member 18 can be reduced in weight by forming the substrate 20 from a foaming synthetic resin or forming a hollow portion inside the substrate 20.

  An anode element 22 is attached to the surface side of the substrate 20 using an insulating adhesive mainly composed of an epoxy resin or the like. The anode element 22 is a sheet, a film, or a plate formed of titanium into a thin film, and has a thickness of, for example, 0.3 mm. Specifically, the anode element 22 covers the entire surface of the main body 24, and one end thereof extends to the front surface side of the first fitting portion 26, and the other end extends to the back surface side of the second fitting portion 28. As shown in FIG. That is, the anode element 22 is attached to the substrate 20 so as to not only cover the entire front surface side of the substrate 20 but also to the back surface side of the second fitting portion 28.

  The surface of the anode element 22 is preferably covered with an electric catalyst (not shown) of a platinum group metal such as platinum or a platinum ruthenium alloy. By covering the surface of the anode element 22 with an electrocatalyst, oxygen can be generated efficiently while suppressing the generation of chlorine.

  Further, the panel member 18 is provided with a plurality of (two in this embodiment) through holes 30 penetrating the first fitting portion 26 and the anode element 22 affixed thereto at a predetermined interval in the width direction. . Further, a plurality of through holes 32 penetrating the second fitting portion 28 and the anode element 22 attached thereto are provided at positions corresponding to the through holes 30. The through holes 30 and 32 are used when the panel member 18 is anchored to the wall surface of the seawater channel 102. When the panel members 18 are connected to each other, the first fitting portion 26 and the second fitting that are adjacent to each other are used. They are formed so as to communicate with each other when the joining portion 28 is overlapped.

  As shown in FIG. 6, when the panel members 18 are connected to each other and installed on the wall surface of the seawater channel 102, the adjacent second fitting portions 28 are overlapped on the first fitting portions 26. Then, anchor bolts 34 are inserted into the through holes 30 and 32 to anchor the panel member 18 to the wall surface of the seawater channel 102. At this time, the anode element 22 that covers the surface of the first fitting portion 26 and the anode element 22 that covers the back surface of the second fitting portion 28 are in surface contact, and the adjacent anode elements 22 are connected to be energized. .

  Thus, the adjacent anode elements 22 are connected to each other so as to be energized only by connecting the panel members 18 and anchoring the seawater channel 102 to each other. At this time, the other end portion of the anode element 22 is wound around the second fitting portion 28, and the edge of the anode element 22 is not exposed in seawater, so that the anode element 22 (and thus the anode body 14) is curled. Is prevented. Further, due to the tightening force of the anchor bolt 34, the entire end portion of the adjacent anode element 22 is evenly pressed by the substrate 20 (the first fitting portion 26 and the second fitting portion 28), and is in surface contact. To do. Therefore, the conductivity of the anode body 14 can be stably secured over a long period of time.

  Then, the structure of the attachment member 10 which is one Example of this invention is demonstrated. As shown in FIGS. 2 and 3, the attachment member 10 is provided on each of the end portions (four sides) of the antifouling panel 12 configured by connecting a plurality of panel members 18. The mounting member 10 has a rail shape, and functions as a cathode conductor for energizing an in-plane cathode member (34, 58, 80) to be described later, and a cathode when electrolyzing seawater. It also functions as an end fixing member for preventing the antifouling panel 12 from falling off or peeling off from the wall surface.

  Specifically, as shown in FIGS. 7 and 8, the attachment member 10 includes a rail portion 38 and a fixture attachment portion 40 formed of a conductive material such as stainless steel. The rail part 38 has the 1st piece 42 and the 2nd piece 44, and the 1st piece 42 is formed in the elongate rectangular flat plate shape. Further, the second piece 44 is formed in a long rectangular flat plate shape that rises in a substantially right angle direction from one end of the first piece 42, and extends over the entire length of the first piece 42. That is, the rail portion 38 is formed in an L-shaped cross section by the first piece 42 and the second piece 44, and when attaching the attachment member 10 to the end portion of the antifouling panel 12, The end of the antifouling panel 12 is fitted into a groove formed by the wall surface of the seawater channel 102 (see FIG. 3).

  The fixture attaching portion 40 is formed in a rectangular plate shape protruding in the opposite direction from the second piece 44 from the other end of the first piece 42, and is formed at predetermined intervals with respect to the longitudinal direction of the rail portion 38. In this embodiment, the fixture attachment portions 40 are formed at both ends and the center of the rail portion 38 in the longitudinal direction. A through hole 46 is formed at the center of the fixture attachment portion 40, and the attachment member 10 is fixed to the wall surface by attaching a fixture such as the anchor bolt 34 to the wall surface of the seawater channel 102 through the through hole 46. The

  Further, an insulator 48 such as a rubber lining for insulating the anode body 14 and the rail portion 38 is provided on the inner surface side of the rail portion 38. The insulator 48 covers the entire inner surface of the rail portion 38, and its end extends to the upper portion of the outer surface of the rail portion 38 and is folded back to the outer surface side. Further, an insulator 50 such as a rubber lining is also provided on the outer surface side of the first piece 42. The insulator 50 adjusts the surface area of the conductive portion in contact with the seawater on the outer surface of the rail so that the seawater can be electrolyzed more efficiently. Moreover, the short circuit between the anode body 14 installed on the other wall surface of the rail portion 38 and the seawater channel 102 (for example, the anode body 14 on the top surface with respect to the rail portion 38 on the side surface) is prevented.

  The length in the longitudinal direction of the mounting member 10 is preferably matched with the length in the width direction of the panel member 18 and is, for example, 2000 mm, and the weight of the mounting member 10 is, for example, 3 kg. Moreover, the thickness of the 1st piece 42 and the 2nd piece 44 is 3 mm, for example, and the thickness of the insulators 48 and 50 is 3 mm, for example. Further, the width of the groove formed by the insulator 48 attached to the inner surface of the rail portion 38 and the wall surface of the seawater channel 102 is set to be slightly larger than the thickness (for example, 10.3 mm) of the antifouling panel 12. For example, 12 mm. Moreover, the height of the groove part is 25 mm, for example. That is, the attachment member 10 prevents the antifouling panel 12 from dropping or peeling off by holding the end of the antifouling panel 12 with a certain degree of freedom.

  In such a mounting member 10, the conductive portion in contact with seawater, that is, the outer surface side of the second piece 44 of the rail portion 38, the fixture mounting portion 40, and the like act as a cathode. In addition, conduction | electrical_connection between adjacent attachment members 10 is ensured by connecting the fixture attachment parts 46 using the flat conductor 52 and the anchor volt | bolt 34 which are formed with stainless steel etc. (FIG. 2). reference).

  Further, in the antifouling system 100, a plurality of cathode panels 54 extending in the width direction are provided on the surface side of the antifouling panel 12 (see FIGS. 2 and 3). The cathode panels 54 are provided at a predetermined interval with respect to the connecting direction, for example, at a rate of about one for the five panel members 18.

  Specifically, as shown in FIGS. 9 and 10, the cathode panel 54 includes a substrate 56, a cathode body 58, and an anode element 60. The substrate 56 is formed in a long rectangular flat plate shape using an insulating material, for example, a synthetic resin such as a vinyl chloride resin or a polyolefin resin. The length of the substrate 56 is, for example, 2000 mm, its width (length in the connecting direction) is, for example, 70 mm, and its thickness is, for example, 10 mm. A cathode body 58 is embedded in the substrate 56. The cathode body 58 is formed in a long rectangular flat plate shape from a metal such as stainless steel, and extends over the entire length of the substrate 56 in the longitudinal direction. The width of the cathode body 58 is, for example, 30 mm, and the thickness thereof is, for example, 3 mm.

  An anode element 60 similar to the panel member 18 is attached to the surface side of the substrate 56. Specifically, the anode element 60 covers the entire surface of the substrate 56, and both ends of the anode element 60 extend to the back surface side end portion of the substrate 56, that is, the substrate 56 is wound up to the back surface side end portion of the substrate 56. It is pasted.

  The cathode panel 54 is provided with a mounting hole 62 that penetrates the substrate 56, the cathode body 58, and the anode element 60 at positions corresponding to the through holes 30 and 32 of the panel member 18. The attachment hole 62 is used for attaching the cathode panel 54 to the surface side of the antifouling panel 12. In this embodiment, as shown in FIGS. 3 and 11, the anchor bolt 34 for connecting the panel member 18 and fixing it to the wall surface of the seawater channel is used to attach the cathode panel 54 to the antifouling panel 12. Is done. The mounting hole 62 is enlarged in the portion above the cathode body 58 so as to ensure insulation between the anode element 60 and the anchor bolt 34. A core member 64 is attached to the through holes 30 and 32 of the panel member 18 in order to insulate the anode body 14 and the anchor bolt 34 from each other. The core member 64 is formed of an insulating material such as synthetic resin or rubber, and includes a cylindrical portion and a flange portion formed at the upper end thereof.

  When the cathode panel 54 is attached to the antifouling panel 12 using the anchor bolt 34, the anode element 22 of the panel member 18 and the anode element 60 of the cathode panel 54 are in surface contact with each other so as to be energized. The anode element 60 also becomes a part of the anode body 14. At this time, both end portions of the anode element 60 are wound up to the end portion on the back surface side of the substrate 56, and the edge of the anode element 60 is not exposed in seawater, so that the anode element 60 is prevented from dripping. In addition, since the fastening force of the anchor bolt 34 is applied, the entire end portions of the anode element 60 are evenly pressed by the substrate 56 and brought into surface contact with each other, so that the conductivity of the anode body 14 is stable over a long period of time. Can be secured. In addition, since the cathode panel 54 is installed on the antifouling panel 12, it can be easily replaced when a malfunction such as corrosion occurs.

  Further, a projection 66 is formed on the head of the anchor bolt 34 that fixes the cathode panel 54 so as to protrude about several cm from the surface of the cathode panel 54. The protrusion 66 is not necessarily formed, but seawater can be electrolyzed more efficiently by the portion protruding from the surface acting as a cathode.

  Returning to FIGS. 9 and 10, the cathode panel 54 is formed with mounting holes 68 that penetrate the substrate 56, the cathode body 58, and the anode element 60 at both ends in the longitudinal direction. The attachment hole 68 is used for attaching the cathode panel 54 to the surface side of the antifouling panel 12 and is used for conducting the rail portion 38 of the attachment member 10 and the cathode body 58 of the cathode panel 54. For example, a branch portion may be formed in the conductive body 52 that connects the adjacent mounting members 10 to each other, and the branch portion may be connected to the cathode body 58 of the cathode panel 54 and fixed by the anchor bolt 34 (see FIG. 2). As a result, the rail portion 38 of the mounting member 10 is connected to the anchor bolt 34 and the cathode body 58 (in-plane cathode member) installed in the antifouling panel region, and for the cathode for energizing these in-plane cathode members 34 and 58. It also functions as a conductor.

  A through hole is also formed in the panel member 18 at a position corresponding to the mounting hole 68 of the cathode panel 54, and the anode body 14 and the anchor bolt 34 are insulated from the through hole of the panel member 18. A core member 64 is attached. The mounting hole 68 is expanded in diameter above the cathode body 58 so that insulation between the anode element 60 and the anchor bolt 34 can be secured and the conductive body 52 can be connected. Notched.

  Next, an example of a method for installing the antifouling system 100 in the seawater channel 102 will be described. Here, the case where the attachment member 10 and the antifouling panel 12 are installed on the side surface of the seawater channel 102 will be described. However, the attachment member 10 and the antifouling panel are similarly applied to the top and bottom surfaces of the seawater channel 102. 12 can be installed. The installation of the attachment member 10 and the antifouling panel 12 to the seawater channel 102 may be performed by removing the seawater from the seawater channel 102, or when the seawater channel 102 is in use and the seawater cannot be removed. May be performed in seawater.

  With reference to FIGS. 2 and 3, first, the attachment members 10 at the lower end (bottom side) are arranged in a straight line on the side surface of the seawater channel 102, and are sequentially attached using the anchor bolts 34. Next, the panel members 18 are sequentially carried in from an inspection manhole or the like. At this time, the end portion of the antifouling panel 12 is fitted into a groove formed by the inner surface side of the rail portion 38 of the mounting member 10 and the wall surface of the seawater channel 102, and the panel member 18 is conveyed so as to slide on the rail. If it does, conveyance of the panel member 18 can be performed smoothly.

  Subsequently, the second fitting portion 28 of the panel member 18 subsequent to the first fitting portion 26 of the leading panel member 18 is overlapped, and the anchor bolts 34 are inserted into the through holes 30 and 32, and the seawater channel 102. The panel member 18 is fixed to the wall surface (see FIG. 6). At this time, the front panel member 18 and the succeeding panel member 18 are placed on the mounting member 10 (that is, the end portion of the panel member 18 in the groove formed by the mounting member 10 and the wall surface of the seawater channel 102). When the panel member 18 is installed in a temporarily placed state, the temporary fixing of the heavy panel member 18 to the wall surface is facilitated, and the displacement of the panel member 18 is prevented. Therefore, the installation work of the panel member 18 becomes easy. Thereafter, in the same manner, the subsequent panel member 18 is connected and anchored to form the antifouling panel 12 over the entire construction portion.

  Further, when the antifouling panel 12 is formed, the panel members 18 are connected and anchored at a ratio of about one to the five panel members 18, and at the same time, the cathode panel 54 is anchored. (See FIG. 11).

  When the antifouling panel 12 is formed over the entire construction portion, the attachment member 10 is attached to the upper end (top surface side) of the antifouling panel 12 and both ends in the connecting direction. When attaching the attachment members 10 to both ends in the connecting direction, with respect to the space below the second fitting portion 28 of the leading panel member 18 and above the first fitting portion 16 of the last panel member 18, A spacer 70 formed in a rectangular parallelepiped shape is preferably attached. Adjacent mounting members 10 and adjacent mounting members 10 and the cathode panel 54 are connected to each other so as to be energized using the conductive body 52 and the anchor bolt 34. Thus, the attachment member 10 functions as a cathode conductor that energizes the anchor bolt 34 and the cathode body 58 that function as an in-plane cathode member.

  Thereafter, the anode body 14 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 mounting member 10. Then, the installation work of the antifouling system 100 to the sea channel 102 is completed.

  According to this embodiment, in addition to functioning as a cathode and a cathode conductor, the attachment member 10 can also function as an end fixing member that fixes the end of the antifouling panel 12. It is possible to reliably prevent the panel 12 from falling off or peeling off.

  Further, when the panel member 18 is connected and anchored to the wall surface, this operation can be performed with the panel member 18 placed on the mounting member 10. Accordingly, the temporary fixing of the heavy panel member 18 to the wall surface is facilitated, and the displacement of the panel member 18 is prevented, so that the installation work of the panel member 18 (antifouling panel 12) is facilitated. .

  In the above-described antifouling system 100, the cathode panel 54 is provided on the antifouling panel 12, but the panel member itself can also function as a cathode panel. Hereinafter, the configuration of the panel member 110, which is another example of the panel member, will be described with reference to FIGS. As shown in FIGS. 12 and 13, the panel member 110 is connected to the five panel members 18 at a ratio of about one, similarly to the cathode panel 54 shown in FIG. 9. To put it simply, the panel member 110 is obtained by embedding a cathode body inside the substrate 20 of the panel member 18 shown in FIG. Since they are the same, common parts are given the same numbers, and redundant descriptions are omitted or simplified.

  As shown in FIGS. 14 and 15, the panel member 110 includes a substrate 20, an anode element 22, and a cathode body 80. The substrate 20 is formed of an insulating material and includes a main body 24 formed in a rectangular flat plate shape. A first fitting portion 26 is formed at the lower end of one end of the main body 24 in the connecting direction, and a second fitting portion 28 is formed at the upper end of the other end of the main body 24 in the connecting direction. The anode element 22 covers the entire surface of the main body 24, and one end thereof extends to the surface side of the first fitting portion 26 and the other end extends to the back surface side of the second fitting portion 28. It is pasted. A plurality of through holes 30 and 32 are provided in the first fitting portion 26 and the second fitting portion 28 at predetermined intervals in the width direction.

  A cathode body 80 (in-plane cathode member) is embedded in the main body 24 of the substrate 20. The cathode body 80 is formed in a long rectangular flat plate shape from a metal such as stainless steel and extends over the entire length of the substrate 20 in the width direction. The width of the cathode body 80 is, for example, 30 mm, and the thickness thereof is, for example, 3 mm. Further, the panel member 110 is formed with a mounting hole 82 that penetrates the anode element 22, the main body 24, and the cathode body 80. The mounting hole 82 is used for anchoring the panel member 110 to the wall surface of the seawater channel 102, and is a portion above the cathode body 80 so as to ensure insulation between the anode body 14 and the anchor bolt 34. (See FIG. 13).

  Furthermore, attachment holes 84 that penetrate the anode element 22, the main body 24, and the cathode body 80 are formed at both ends in the width direction of the panel member 110. The mounting hole 84 is used for anchoring the panel member 110 to the wall surface of the seawater channel 102 and is used for electrical connection between the rail portion 38 of the mounting member 10 and the cathode body 80 of the panel member 110. For example, a branch portion may be formed in the conductive body 52 that connects the adjacent mounting members 10 together, and the branch portion may be connected to the cathode body 80 of the panel member 110 and fixed with the anchor bolt 34 (see FIG. 12). The mounting hole 84 is enlarged in diameter above the cathode body 80 so that insulation between the anode element 22 and the anchor bolt 34 can be secured and the conductive body 52 can be connected, and the end in the width direction is cut. It is lacking.

  When the panel member 110 and the panel member 18 are connected to each other and installed on the wall surface of the seawater channel 102, the same operation as that for connecting the panel members 18 may be performed. That is, the adjacent second fitting portion 28 is superimposed on the first fitting portion 26, the anchor bolts 34 are inserted into the through holes 30 and 32, and the panel members 18 and 110 are attached to the wall surface of the seawater channel 102. It is good to fix. Also in this case, since the other end portion of the anode element 22 is wound around the second fitting portion 28 and the edge of the anode element 22 is not exposed in seawater, the anode element 22 (and thus the anode body 14) The drowning is prevented. In addition, due to the tightening force of the anchor bolt 34, the entire end portion of the adjacent anode element 22 is evenly pressed by the substrate 20 and brought into surface contact. Therefore, the conductivity of the anode body 14 can be stably secured over a long period of time. Further, according to the panel member 110, it is possible to perform installation of the cathode extending in the width direction only by being connected to the panel member 18, so that the construction is further simplified and the working efficiency is improved. Furthermore, the surface of the formed antifouling panel 12 (anode body 14) can be kept almost smooth.

  By attaching the attachment member 10 to the end portion of the antifouling panel 12 formed by connecting the panel member 18 and the panel member 110 in this manner, the antifouling panel 12 can be prevented from falling off or peeling off. Further, the installation work of the antifouling panel 12 is facilitated by performing the installation work of the panel members 18 and 110 (antifouling panel 12) in a state of being mounted (supported) on the attachment member 10.

  In the above-described embodiment, the second piece 44 is formed over the entire length of the first piece 42 of the rail portion 38. However, the present invention is not limited to this, and a portion with respect to the longitudinal direction of the first piece 42 is used. Alternatively, the second piece 44 can be formed. For example, a notch may be formed at predetermined intervals in the longitudinal direction with respect to the second piece 44. The first piece 42 is also formed with a plurality of through-holes (notches) arranged in the longitudinal direction, that is, in the form of a long plate having through-holes, so that the mounting member 10 can be reduced in weight. Also good.

  Moreover, in the above-mentioned Example, although the attachment member 10 was made into a 2000 mm long body, the attachment member 10 does not necessarily need to be formed as a long body, and the length of the attachment member 10 can be changed suitably. When shortening the length of the mounting member 10, for example, the mounting member 10 is arranged at a predetermined interval with respect to the end portion of the antifouling panel 12, and a long conductive body 52 is connected between them. It is good to do so.

  Furthermore, in the above-described embodiment, the width of the groove portion formed by the insulator 48 attached to the inner surface of the rail portion 38 and the wall surface of the seawater channel 102 is set to be slightly larger than the thickness of the antifouling panel 12. However, it is not limited to this. The width of the groove portion can be set to be the same as or slightly smaller than the thickness of the antifouling panel 12 and can be fixed by pressing the end surface of the antifouling panel 12 by the second piece 44. Moreover, if the rail part 38 (metal main body) of the attachment member 10 has at least the 1st piece 42, when installing the panel member 18 in the side surface of the seawater channel 102, the member which mounts the panel member 18 The attachment member 10 can be used. That is, when the attachment member 10 is not used as an end fixing member for preventing the antifouling panel 12 from dropping or peeling off, the second piece 44 may not be formed.

  In the above-described embodiment, the attachment member 10 is made to function as a cathode and a cathode conductor, but the attachment member 10 is not necessarily used as a cathode and a cathode conductor. When the attachment member 10 is not used as a cathode conductor, the in-plane cathode members 34, 58, and 80 may be energized by providing a cathode conductor separately. Further, the mounting member 10 can be used as an anode by making the rail portion 38 of the mounting member 10 made of titanium or covering the rail portion 38 with a titanium sheet. In the case where the mounting member 10 is used as an anode, the insulators 48 and 50 are unnecessary.

  In the above-described antifouling system 100, titanium is used as the material of the anode element 22 (anode body 14) that acts as the anode, and the rail portion 38, the anchor bolt 34, and the cathode body 58 of the mounting member 10 that act as the cathode. , 80 and the like are made of stainless steel, but these materials may be appropriately changed as long as seawater can be electrolyzed to generate oxygen. However, it preferably has resistance to corrosion. In addition, since electricity flows also to the cathode, resistance to corrosion can be expected even with a general structural rolled steel material (SS equivalent product) due to the anticorrosion effect.

  In the antifouling system 100 described above, the attachment member 10 is provided on each of the four sides of the antifouling panel 12, and the panel member 110 including the cathode panel 54 and the cathode body 80 is provided at predetermined intervals in the connecting direction. However, it is not limited to this. For example, when the construction length of the antifouling panel 12 is short, the attachment member 10 may be provided only on each of the four sides of the antifouling panel 12 without providing the cathode panel 54 and the panel member 110 and the like. The attachment member 10 may be provided only on any one or three sides of the dirty panel 12. Further, for example, the cathode panel 54, the panel member 110, and the like can be provided at predetermined intervals in the connecting direction, and the mounting member 10 can be provided only in the connecting direction. When the attachment member 10 is not provided at the connection direction end of the antifouling panel 12, the connection direction end of the antifouling panel 12 may be fixed using an anchor bolt 34 or the like.

  Furthermore, in the antifouling system 100 described above, the antifouling panel 12 is formed by connecting the panel member 18 in the pipe axis direction (flowing water direction) of the seawater channel 102, but the panel member is disposed in the circumferential direction of the seawater channel 102. 18 can also be connected. Further, the antifouling system 100 may be applied anywhere as long as it is in contact with seawater. For example, the antifouling system 100 can be applied to a groove-type seawater channel (open water channel) with an open top, a pier or a coastal wall. It can also be applied to. Furthermore, when the applied wall surface is a curved surface and the antifouling panel 12 is formed in a curved plate shape, the mounting member 10 can be bent and deformed in accordance with the curvature.

  It should be noted that the specific numerical values such as the dimensions given above are merely examples, and can be appropriately changed according to necessity such as product specifications.
