Description

  The present invention relates to an antifouling panel member, a structure on which the antifouling panel member is installed, a cathode member, and a connecting structure of the antifouling panel member, and particularly, for example, attached to a wall surface in contact with seawater and generating oxygen by electrolysis of seawater. The present invention relates to an antifouling panel member that forms an antifouling panel that prevents adhesion of marine organisms, a structure on which the antifouling panel member is installed, a cathode member, and a connecting structure of the antifouling panel member.

  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. 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 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 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 electric conductivity between adjacent panel-like titanium plates is to be secured. However, in the technique of Patent Document 1, since the edge of the upper overlapping portion of the panel-like titanium plate is exposed in a free state, the upper overlapping portion is easy to bend and there is a gap between the lower overlapping portion. It is likely to occur. Therefore, in the technique of Patent Document 1, the surface contact between the upper and lower overlapping portions cannot be properly maintained, and there is a possibility that the conductivity of the anode body cannot be stably maintained over a long period of time. In particular, considering the weight reduction and cost reduction of antifouling panel members, it is desirable to reduce the thickness of the panel-like titanium plate. The part becomes easier to drown. In addition, if a gap is generated between the upper and lower overlapping portions, microorganisms may enter the back side of the panel-like titanium plate from the gap, and the attachment of marine organisms may proceed using the microorganisms as nutrients.

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

  Another object of the present invention is to provide an antifouling panel member, a structure on which the antifouling panel member is installed, a cathode member, and a connecting structure of the antifouling panel member, capable of stably ensuring the electrical conductivity of the anode body over a long period of time.

Basically, panel members 10 connected to the bottom surface, the side surface, and the top surface of the seawater channel 102 are connected in a row in the tube axis direction. 10 can also be connected and installed in the width direction.

  In this embodiment, the length in the connecting direction of the panel member 10 is 800 mm, and the length in the width direction is 2000 mm. The size of the panel member 10 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.

  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.

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 anode element 22 does not necessarily need to cover the entire front surface side of the first fitting portion 26 and the entire back surface side of the second fitting portion 28, and the first fitting portion 26 and the second fitting portion 28 are not covered. If the anode elements 22 are in contact with each other and can be energized when fitted, and the end edges are not exposed in seawater, a part of the first fitting portion 26 and the second fitting portion 28 is used. It is good also as a structure covered.

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.

  2 and 3, in the antifouling system 100, the first cathode member 36 is provided at each of the end portions (four sides) of the antifouling panel 12 configured by connecting a plurality of panel members 10. . The first cathode member 36 has a rail shape, functions as a cathode when electrolyzing seawater, and is an end fixing member for preventing the antifouling panel 12 from falling off and peeling from the wall surface of the seawater channel 102. Also works.

  Specifically, as shown in FIGS. 7 and 8, the first cathode member 36 includes a rail portion 38 and a fixing portion 40 formed of a metal such as stainless steel. The rail portion 38 includes a first piece 42 and a second piece 44, and the first piece 42 is formed in a long rectangular flat plate shape and extends along the end surface of the antifouling panel 12. In addition, the second piece 44 is formed in a long rectangular flat plate shape projecting at a right angle from one end of the first piece 42, and extends along the surface of the antifouling panel 12. 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 the end portion of the antifouling panel 12 is formed in a groove portion formed by the inner surface side and the wall surface of the seawater channel 102. Is inserted. The length of the rail portion 38 in the longitudinal direction is, for example, 2000 mm, and the thickness of the first piece 42 and the second piece 44 is, for example, 3 mm.

  The fixing portion 40 is formed in a rectangular plate shape protruding from the other end of the first piece 42 in the opposite direction to the second piece 44, and is formed at predetermined intervals with respect to the longitudinal direction of the rail portion 38. A through hole 46 used for anchoring is formed in the center of the fixing portion 40.

  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 portion 38 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 thickness of the insulators 48 and 50 is 3 mm, for example.

  In such a first cathode member 36, the conductive portion in contact with seawater, that is, the outer surface side of the second piece 44 of the rail portion 38 and the fixing portion 40 act as a cathode. 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 first cathode member 36 holds the antifouling panel 12 with a certain degree of freedom within a range in which the antifouling panel 12 can be prevented from falling off or peeling off. In addition, the conduction | electrical_connection between the adjacent 1st cathode members 36 is ensured by connecting the fixing | fixed part 46 using the flat conductor 52 formed by stainless steel etc. (refer FIG. 2).

  Further, in the antifouling system 100, a plurality of second cathode members 54 extending in the width direction are provided on the surface side of the antifouling panel 12 (see FIGS. 2 and 3). The second cathode member 54 is provided at a predetermined interval with respect to the connecting direction, for example, at a rate of about one for the five panel members 10.

  Specifically, as shown in FIGS. 9 and 10, the second cathode member 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 10 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 second cathode member 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 10. The attachment hole 62 is used for attaching the second cathode member 54 to the surface side of the antifouling panel 12. In this embodiment, as shown in FIG. 3 and FIG. 11, for attaching the second cathode member 54 to the antifouling panel 12, the anchor bolt 34 for connecting the panel member 10 and fixing it to the wall surface of the seawater channel. Is used. 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 10 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 second cathode member 54 is attached to the antifouling panel 12 using the anchor bolt 34, the anode element 22 of the panel member 10 and the anode element 60 of the second cathode member 54 are in surface contact with each other so as to be energized. The anode element 60 of the second cathode member 54 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 2nd cathode member 54 is installed on the antifouling panel 12, when a malfunction, such as corrosion, arises, replacement | exchange is easy.

  Further, a projection 66 is formed on the head of the anchor bolt 34 that fixes the second cathode member 54 so as to protrude from the surface of the second cathode member 54 by about several centimeters. 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 second cathode member 54 is formed with attachment 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 to attach the second cathode member 54 to the front surface side of the antifouling panel 12 and electrically connects the rail portion 38 of the first cathode member 36 and the cathode body 58 of the second cathode member 54. Used to make For example, a branch portion may be formed in the conducting body 52 that connects the adjacent first cathode members 36, and the branch portion may be connected to the cathode body 58 of the second cathode member 54 and fixed by the anchor bolt 34 (FIG. 2). reference).

  A through hole is also formed in the panel member 10 at a position corresponding to the mounting hole 68 of the second cathode member 54, and the anode body 14 and the anchor bolt 34 are insulated from the through hole of the panel member 10. A core member 64 is mounted. 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.

  2 and 3 exemplify a mode in which the second cathode member 54 is attached to the connection portion (through holes 30 and 32) of the panel member 10, the present invention is not limited to this, and the second cathode member 54 It can also be attached to other parts of the panel member 10, for example, the central part of the panel member 10. That is, the second cathode member 54 can be mounted on the surface of the antifouling panel 12 (panel member 10) using a mounting tool different from the anchor bolt 34 that is a fixing tool for fixing the panel member 10 to the wall surface. . The attachment in this case is only required to fix the second cathode member 54 to at least the antifouling panel 12 and is not necessarily an anchor bolt for fixing the antifouling panel 12 and the second cathode member 54 to the wall surface of the seawater channel 102. .

  Next, an example of a method for installing the antifouling system 100 (panel member 10) in the seawater channel 102 will be described. Here, the case where the panel member 10 is installed on the side surface of the sea channel 102 will be described. However, the panel member 10 can be similarly installed on the top surface and the bottom surface of the sea channel 102. The panel member 10 may be installed in the seawater channel 102 by removing seawater from the seawater channel 102. If the seawater channel 102 is in use and cannot be removed, You may make it perform.

  With reference to FIGS. 2 and 3, first, the first cathode members 36 at the lower end (bottom surface 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 10 are sequentially carried in from an inspection manhole or the like. Then, the end of the panel member 10 is fitted into a groove formed by the first cathode member 36 supported by the first cathode member 36 (that is, the first cathode member 36 and the wall surface of the seawater channel 102). In the temporarily placed state), the second fitting portion 28 of the panel member 10 following the first fitting portion 26 of the leading panel member 10 is overlapped, and the anchor bolt 34 is inserted into each of the through holes 30 and 32. The panel member 10 is fixed to the wall surface of the sea channel 102 (see FIG. 6). Thereafter, the panel member 10 is connected and anchored in the same manner, thereby forming the antifouling panel 12 over the entire construction portion.

  Further, when the antifouling panel 12 is formed, the panel members 10 are connected to each other and anchored at a ratio of about one to the five panel members 10, and the second cathode member 54 is also anchored. (See FIG. 11).

  When the antifouling panel 12 is formed over the entire construction portion, the first cathode member 36 is attached to the upper end (top surface side) of the antifouling panel 12 and both ends in the connecting direction. When the first cathode members 36 are attached to both ends in the connecting direction, the space is below the second fitting portion 28 of the leading panel member 10 and above the first fitting portion 16 of the last panel member 10. Thus, a spacer 70 formed in a rectangular parallelepiped shape is preferably attached. Further, the adjacent first cathode members 36 and the adjacent first cathode member 36 and second cathode member 54 are connected so as to be energized using the conductive body 52 and the anchor bolt 34.

  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 first cathode member 36. Thus, the installation work of the antifouling system 100 to the seawater channel 102 is completed.

  According to this embodiment, the other end portion of the anode element 22 is wound up to the back surface side of the second fitting portion 28 and the edge of the anode element 22 is not exposed in seawater. This prevents the anode body 14) from twisting. 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 this embodiment, the adjacent anode elements 22 are connected to each other so as to be energized only by fitting the end portions of the panel member 10 so as to overlap each other and anchoring the seawater channel 102 to each other. Moreover, the magnitude | size of the panel member 10 is set to the largest magnitude | size in the range which does not interfere with construction work. Therefore, the attachment work to the wall surface becomes easy and the construction speed is improved, so that it can be suitably used for construction in seawater and the cost can be reduced.

  Furthermore, since the antifouling panel 12 is formed using one type of panel member 10 standardized with a simple shape, the effect of cost reduction by mass production is great. Further, the anode element 22 is prevented from being twisted, and the anode element 22 (anode body 14) can be thinned. Therefore, the cost can be reduced by making the anode element 22 thin.

  In the antifouling system 100 described above, the second cathode member 54 is provided on the antifouling panel 12, but the panel member itself can also function as the second cathode member. That is, a cathode-equipped antifouling panel member can be obtained. Hereinafter, with reference to FIGS. 12-15, the structure of the panel member 110 which is the other Example of this invention is demonstrated. As shown in FIGS. 12 and 13, the panel member 110 is connected to the five panel members 10 at a rate of about one, similarly to the second cathode member 54 shown in FIG. To put it simply, the panel member 110 is obtained by embedding a cathode body inside the substrate 20 of the panel member 10 shown in FIG. Since they are the same, common parts are given the same numbers, and redundant descriptions are omitted or simplified. The same applies to the cathode-fouled antifouling panel members 120 and 130, which are other examples described later.

  As shown in FIGS. 14 and 15, the panel member 110 is an antifouling panel member having a cathode, and 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 first fitting portion 26 and the second fitting portion 28 have a rectangular cross-sectional shape and are formed over the entire length of the substrate 20 in the width 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 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). A protrusion 66 is formed on the head of the anchor bolt 34 and protrudes from the surface of the panel member 110 by several cm. 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.

  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 conducting the rail portion 38 of the first cathode member 36 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 first cathode members 36, 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 10 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 10 may be performed. That is, the adjacent second fitting portion 28 is superposed on the first fitting portion 26, the anchor bolt 34 is inserted into each through hole 30, 32, and the panel members 10, 110 are placed on 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 install the cathode extending in the width direction only by being connected to the panel member 10, so that the construction is further simplified and the working efficiency is improved. Further, the surface of the formed antifouling panel 12 (anode body 14) can be kept almost smooth.

  In addition, the length of the connection direction of the panel member 110 is not specifically limited, For example, it can also be made the same as the panel member 10 and can also be made into the length comparable as the 2nd cathode member 54. FIG. If the length of the connecting direction of the panel member 110 is shortened, the replacement of the panel member 110 is facilitated when a malfunction such as corrosion of the cathode body 80 occurs.

  Further, in the panel member 110 shown in FIG. 14, the cathode body 80 is embedded in the main body 24 and the protrusion 66 is formed on the anchor bolt 34 so as to act as the cathode. A plate-like cathode body 92 can be provided by forming a groove portion 90 on the side and fitting into the groove portion 90.

  For example, referring to FIGS. 16 and 17, in panel member 120 according to another embodiment of the present invention, groove portion 90 extending in the width direction is formed on the surface of main body 24 of substrate 20. The anode element 22 covers the entire surface of the main body 24 including the inner surface of the groove portion 90, 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. Further, an insulator 94 such as a rubber lining is provided on the anode element 22 attached to the inner surface of the groove portion 90, and a cathode body that is formed into a long rectangular flat plate from a metal such as stainless steel. 92 is provided. The cathode body 92 is fixed to the substrate 20 by using a fixing tool 96 such as an insulating screw or rivet, and an end portion of the cathode body 92 is connected to the first cathode member 36.

  In such a panel member 120, the surface part of the cathode body 92 exposed in seawater acts as a cathode. However, the cathode body 92 may be fixed to the substrate 20 using a conductive fixing tool formed of a metal such as stainless steel instead of the fixing tool 96 having an insulating property. For example, as a conductive fixture, using the anchor bolt 36 that fixes the panel member 120 to the wall surface of the seawater channel 102, the head of the anchor bolt 36 is left as it is, or the protrusion 66 is formed on the head, You may make it act as a cathode. In this case, it is necessary to ensure insulation between the conductive fixture and the anode element 22 by using an insulating core member 64 or by cutting the anode element 22 into a larger size.

  Further, for example, instead of using the insulating fixture 96, the anchor bolt 36, etc., the groove 90 is formed in a tapered shape as in the panel member 130 according to another embodiment of the present invention shown in FIG. The plate-like cathode body 92 may be fixed to the substrate 20 by forming the body 92 in a trapezoidal cross section. According to this panel member 130, the surface of the formed antifouling panel 12 (anode body 14) can be kept substantially smooth.

  In each of the above-described embodiments (panel members 10, 110, 120, and 130), the first fitting portion 26 and the second fitting portion 28 are formed to have a rectangular cross-sectional shape. The cross-sectional shapes of 26 and 28 are not particularly limited, and may be formed in a trapezoidal shape or a triangular shape. For example, as shown in FIG. 19, the front surface of the first fitting portion 26 and the back surface of the second fitting portion 28 may be formed in a slope shape so as to become thicker toward the end surface. Further, for example, as shown in FIG. 20, a stepped locking portion 98 can be formed in each of the first fitting portion 26 and the second fitting portion 28. That is, the front surface of the first fitting portion 26 and the back surface of the second fitting portion 28 do not necessarily have to be parallel to the wall surface to be installed, and have slopes or steps extending in an oblique direction with respect to the wall surface. It may be a surface. Furthermore, for example, as shown in FIG. 21, the first fitting portion 26 and the second fitting portion 28 are not only fitted so as to be overlapped in the vertical direction, but also a second fitting formed in a cross-sectional groove shape. The first fitting portion 26 may be fitted in the groove portion of the portion 28 from the lateral direction.

  According to the embodiment shown in FIG. 19 and FIG. 20, since the displacement of the connecting direction when the first fitting portion 26 and the second fitting portion 28 are overlapped is prevented, the panel member 10 can be easily positioned. Thus, the installation work of the panel member 10 on the wall surface of the seawater channel 102 becomes easy. Further, according to the embodiment shown in FIG. 21, since the shift in the thickness direction (front and back direction) of the panel member 10 is prevented, the positioning of the panel member 10 is facilitated, and the installation work of the panel member 10 is facilitated.

  In addition, when the 1st fitting part 26 and the 2nd fitting part 28 are made to fit, a level | step difference may arise in the surface side or back surface side of the antifouling panel 12 formed, It is preferable that the surface of the second fitting portion 28 and the surface of the main body 24 be flush with each other so as not to hinder the flow. Moreover, it is preferable that the back surface of the first fitting portion 26 and the back surface of the main body 24 be flush with each other so that no gap is generated between the antifouling panel 12 and the wall surface of the seawater channel 102.

  Further, in each of the above-described embodiments, the through holes 30 and 32 are formed in the first fitting portion 26 and the second fitting portion 28, and the anchor bolt 36 is attached thereto, thereby fixing the panel member 10. However, it is not limited to this. For example, a through hole may be formed at the end of the main body 24 in the connecting direction, and the anchor bolt 36 may be attached to the through hole. However, in order to cause the end portions of the anode elements 22 to come into surface contact with each other more firmly by causing the fastening force of the anchor bolt 34 to act directly on the first fitting portion 26 and the second fitting portion 28, the first fitting is performed. It is preferable to attach the anchor bolt 34 to the joint portion 26 and the second fitting portion 28.

  Further, apart from the through holes 30 and 32, a through hole is formed in the central part of the connecting direction of the panel member 10, and the panel member 10 is anchored to the wall surface of the seawater channel 102 using this through hole. Also good. Thereby, the panel member 10 can be more firmly fixed to the wall surface of the seawater channel 102. The second cathode member 54 may be attached using a through hole separately formed in the panel member 10 as described above.

  Furthermore, in each of the above-described embodiments, the first fitting portion 26 and the second fitting portion 28 are formed over the entire length of the main body 24 in the width direction. It can also be formed partially.

  Moreover, in each of the above-described embodiments, the end portions of the adjacent anode elements 22 are brought into surface contact with each other so that they can be energized. However, when seawater is removed from the seawater channel 102 and construction can be performed, You may make it apply | coat an electrically conductive adhesive with respect to the edge part surface (namely, contact part) of the anode element 22. FIG. As a result, the ends of the adjacent anode elements 22 are more firmly connected to each other and are more resistant to corrosion, so that the conductivity of the anode body 14 can be reliably maintained over a longer period.

  Further, in each of the above-described embodiments, titanium is adopted as the material of the anode element 22 (anode body 14) that acts as the anode, the anchor bolt 34 that acts as the cathode, the rail portion 38 of the first cathode member 36, and the cathode body 58. , 80, 92 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 first cathode member 36 is provided on each of the four sides of the antifouling panel 12, and the second cathode member 54 and the cathode-equipped panel member 110 are provided at predetermined intervals in the connecting direction. 120, 130 are not limited to this, but the first cathode member 36, the second cathode member 54, the cathode-equipped panel members 110, 120, 130, and the like can be omitted as appropriate. For example, when the construction length of the antifouling panel 12 is short, the first cathode is provided on each of the four sides of the antifouling panel 12 without providing the second cathode member 54 and the cathode-equipped panel members 110, 120, 130, etc. The member 36 may be provided only, or the first cathode member 36 may be provided only on any one or three sides of the antifouling panel 12. Further, for example, the second cathode member 54, the cathode-equipped panel members 110, 120, 130, and the like may be provided at predetermined intervals in the connecting direction, and the first cathode member 36 may be provided only in the connecting direction. Further, for example, the first cathode member 36 is not provided, but the second cathode member 54, the cathode-equipped panel members 110, 120, and 130 are provided at predetermined intervals in the connecting direction, and the cathodes extend in the connecting direction. It can also be connected by an electrical conductor. In addition, when the 1st cathode member 36 is not provided in the connection direction edge part of the pollution protection panel 12, it is good to fix the connection direction edge part of the pollution protection panel 12 using the anchor volt | bolt 34 grade | etc.,.

  Furthermore, in the above-described antifouling system 100, 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 is disposed in the circumferential direction of the seawater channel 102. 10 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.

  Furthermore, in the antifouling system 100 described above, the panel members 10 having the same shape are connected. However, the antifouling panel 12 can also be formed by connecting panel members having different shapes.
