     BACKGROUND ART 
     With the trend of stricter international regulations on environmental pollution and greenhouse gas in recent years, renewable energy systems such as photovoltaic systems are being actively studied in order to replace the use of fossil fuels such as coal. The photovoltaic system is a power generation system that uses solar heat to produce electricity, and may be classified into a terrestrial photovoltaic system and an overwater photovoltaic system according to the installation environment thereof. The overwater photovoltaic system is a system in which photovoltaic panels are installed to float on the water such as seawalls, seas, streams, rivers, dams, reservoirs, and freshwater lakes. The overwater photovoltaic system is in the spotlight because it can overcome the space constraints on the ground and have photovoltaic facilities installed in a large space without damaging agricultural land or forests. 
     In addition, the overwater photovoltaic system is also advantageous in that it can have enhanced power generation efficiency by virtue of cooling effects above the surface of water, reduce direct sunlight on the surface of water to prevent green algae and red algae, and increase the number of fish living therebelow.

     Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. 
       FIG.  1    is a view illustrating an overwater photovoltaic panel installation structure according to an embodiment of the present disclosure. 
     Referring to  FIG.  1   , the overwater photovoltaic panel installation structure, which is designated by reference numeral  1 , according to the embodiment of the present disclosure is installed in the ocean or freshwater lake, is moored while floating on the surface of water by buoyancy, and provides a growth space where aquatic organisms can grow. 
     In more detail, the overwater photovoltaic panel installation structure  1  includes buoyancy bodies  130  spaced apart from each other, a photovoltaic panel support assembly  110  supported on the buoyancy bodies  130 , a plurality of photovoltaic panels  120  supported by the photovoltaic panel support assembly  110 , an environment-friendly marine-farm-type mooring anchor module connected to the photovoltaic panel support assembly  110 , configured to moor the photovoltaic panel support assembly  110  on the water S, and seated on the floor surface of the ocean, a connection unit  400  having one side connected to the photovoltaic panel support assembly  110  and the other side fixed to the environment-friendly marine-farm-type mooring anchor module, and a power cable  200  for transmitting electric power generated by the photovoltaic panels to a management device  500  on the ground L. 
     Each of the photovoltaic panels  120  is a power generation unit that generates electric power based on incident sunlight, and may be formed of, for example, a polysilicon solar panel or a CIGS solar panel. 
     The photovoltaic panel support assembly  110  provides an installation place where the photovoltaic panel  120  is installed. The photovoltaic panel support assembly  110  may include a photovoltaic panel support frame (not shown) that allows the photovoltaic panel  120  to be installed while being oriented at a predetermined angle and a main frame (not shown) in which the photovoltaic panel support frame is installed and including a work plate or the like. The photovoltaic panel support assembly  110  may be made of, for example, a lightweight material having corrosion resistance, such as metal or fiber reinforced plastic (FRP). In addition, the main frame of the photovoltaic panel support assembly  110  includes a plurality of support members pivotably connected to each other so as to stably support the photovoltaic panel  120  against an external force generated by storms. 
     Each of the buoyancy bodies  130  is made of, for example, fiber reinforced plastic (FRP), and is filled therein with air or a lightweight polymer material such as Styrofoam to be floatable on the water S. The photovoltaic panel support assembly  110  is disposed on the plurality of buoyancy bodies  130 . 
     The environment-friendly marine-farm-type mooring anchor module is made of a heavy material such as stone or reinforcing steel, and is seated or fixed on the floor surface of the ocean such as the seabed. In the state in which the environment-friendly marine-farm-type mooring anchor module made of heavy material is seated or fixed on the floor surface of the ocean B so as to be immobile, the photovoltaic panel support assembly  110  connected to the environment-friendly marine-farm-type mooring anchor module by the connection unit  400  may remain moored at a specific position. 
     In the present embodiment, the environment-friendly marine-farm-type mooring anchor module may consist of a plurality of environment-friendly marine-farm-type mooring anchor modules. The weight and number of environment-friendly marine-farm-type mooring anchor modules may be determined according to the size of the photovoltaic panel support assembly  110  or the like. 
     In the present embodiment, the photovoltaic panel support assembly  110  further includes a floating connection member  140  formed separately from the main frame. 
     The floating connection member  140  is directly connected to the environment-friendly marine-farm-type mooring anchor module by the connection unit  400 . The floating connection member  140  includes a floating connection member body  141  formed to be floatable on the water S and a connection bracket  142  formed on one side of the floating connection member body  141  and connected to the main frame by an auxiliary connection unit. 
     In the present embodiment, the connection unit  400  and the auxiliary connection unit may each be made of, for example, a metal material, a fiber material, a rubber material, or the like. 
     The overwater photovoltaic panel installation structure  1  according to the present embodiment can be suppressed from being damaged by an external force such as storms as the main frame of the photovoltaic panel support assembly  110  is connected to the environment-friendly marine-farm-type mooring anchor module through the floating connection member  140  capable of relative motion. 
     The management device  500  is connected to the power cable  200  for transmitting electric power to supply the received electric power to a power distribution network, and so on. The management device  500  may include a battery unit (not shown) configured to temporarily store electric power therein. In addition, the management device  500  may receive the operating state information of the photovoltaic panel  120  from the power cable  200  and transmit the power generation status of the photovoltaic panel  120  to the outside. 
     The power cable  200  is connected at one side thereof to the photovoltaic panel  120 , in which state the power cable  200  is connected at one end thereof to the management device  500  while being disposed along the floor surface of the ocean B. In this case, the power cable  200  is disposed such that a portion thereof is covered by the environment-friendly marine-farm-type mooring anchor module. That is, a portion of the power cable  200  is fixed to the floor surface of the ocean B due to the load of the environment-friendly marine-farm-type mooring anchor module, thereby enabling the power cable  200  to be suppressed from moving due to ocean currents or the like. The environment-friendly marine-farm-type mooring anchor module may have a cable fixing groove  315  formed to stably fix the power cable  200 . 
     The environment-friendly marine-farm-type mooring anchor module according to the present embodiment provides a growth space in which aquatic organisms can grow in an aquatic ecosystem, while simultaneously allowing the photovoltaic panel installation structure  1  to be stably moored at a predetermined position by the load thereof. 
     Hereinafter, the configuration of the environment-friendly marine-farm-type mooring anchor module of the overwater photovoltaic panel installation structure  1  according to the present embodiment will be described in more detail. 
       FIG.  2    is a view illustrating an environment-friendly marine-farm-type mooring anchor module of the overwater photovoltaic panel installation structure of  FIG.  1   .  FIG.  3    is a view illustrating the internal configuration of the mooring anchor module of  FIG.  2   . 
     Referring to  FIGS.  2  and  3   , the environment-friendly marine-farm-type mooring anchor module according to the present embodiment includes an anchor module body  310  defining an external appearance thereof, a frame section  340  disposed inside the anchor module body  310  and made of a more rigid material than the anchor module body  310 , and a connection section  320  exposed through an upper surface  311  of the anchor module body  310  and having both lower ends coupled to the frame section  340 . The anchor module body  310  has a plurality of growth space sections  330  recessed from at least one surface  312  or  313  thereof to provide a growth space for aquatic organisms. The connection section  320  may be a single connection section or consist of a plurality of connection sections. 
     The anchor module body  310  is, for example, in the form of a rectangular parallelepiped or a cube, and is made of stone such as concrete, which is a heavy material. 
     The growth space sections  330  may be defined on surfaces forming the sides of the anchor module body  310 . Each of the growth space sections  330  includes an inlet area  331  disposed on the associated surface  312  or  313  of the anchor module body  310 , a bottom area  332  facing the inlet area  331  and forming a bottom surface of the growth space section  310 , and a side area  333  connecting the inlet area  331  to the bottom area  332 . 
     The inlet area  331  of the growth space section  330  may have, for example, a rectangular shape. Each of the growth space sections  330  has more pores than in other portions of the anchor module body  310  where the growth space sections  330  are not defined. Accordingly, it is possible to provide a space in which aquatic organisms, including aquatic plants such as laver and sea mustard and aquatic animals such as shellfish, whelks, and barnacles, can settle and grow more smoothly. 
     In the growth space section  330 , the inlet area  331  is larger in size than the bottom area  332 , and the side area  333  is inclined toward the inlet area  331  from the bottom area  332 . 
     The distance between the inlet area  331  and the bottom area  332 , that is, the recessed depth of the growth space section  330  is 1/20 to ⅓ of the distance between one of the sides of the anchor module body  310  and the other side facing the same. 
     In the present embodiment, the growth space sections  330  may be configured such that three growth space sections are arranged in one row in the longitudinal direction on each surface  312  or  313  of the anchor module body  310 . 
     Each of the growth space sections  330  is formed so as not to overlap the frame section  340  of the environment-friendly marine-farm-type mooring anchor module, thereby suppressing exposure of the frame section  340  to the outside. 
     The frame section  340  may be disposed inside the anchor module body  310  to maintain the rigidity of the environment-friendly marine-farm-type mooring anchor module. The frame section  340  may be made of, for example, at least one or a combination of two or more of metal, fiber reinforced polymer (FRP) reinforcing material, glass fiber reinforced polymer (GFRP) reinforcing material, and carbon fiber reinforced polymer (CFRP) reinforcing material. 
     The frame section  340  includes a plurality of first frames  341  extending in a horizontal direction, a plurality of second frames  342  orthogonal to the first frames  341  in the horizontal direction, and a plurality of third frames  343  bent vertically from the first and second frames  341  and  342 . 
     The connection section  320  includes a connection area  321  rounded and exposed upward from the anchor module body  321  and having both ends embedded within the anchor module body  310 , and a pair of bent areas  322  disposed at and bent in a direction orthogonal to both ends of the connection area  321 . The connection unit  400  is connected to the connection area  321  of the connection section  320 , and the connection section  320  may be a single connection section or consist of a plurality of connection sections. 
     The pair of bent areas  322  of the connection section  320  are latched to one of the first frames  341  of the frame section  340  and another first frame  341  in parallel therewith. The connection section  320  is fixed to the anchor module body  310  with the bent areas  322  latched to the associated respective first frames  341 . Accordingly, when tension is applied to the connection section  320 , the bent areas  322  of the connection section  320  receives a force applied in a direction opposite thereto by the frame section  340 , thereby enabling the overwater photovoltaic panel installation structure to be more stably moored. 
     According to the proposed embodiment, it is possible to provide a more ecologically friendly environment by providing a space in which aquatic organisms can grow smoothly in the body of water where the overwater photovoltaic panel installation structure is installed, and simultaneously by allowing the overwater photovoltaic panel installation structure to be stably moored.

FIG.  8    is a cross-sectional view of the mooring anchor module taken along line VIII-VIII of  FIG.  7   . 
     The overwater photovoltaic panel installation structure according to the present embodiment has substantially the same configuration as that illustrated in  FIGS.  1  to  3   , except that there is a difference in the configuration of the mooring anchor module. Therefore, the main features of the present embodiment will be described below. 
     Referring to  FIGS.  7  and  8   , the environment-friendly marine-farm-type mooring anchor module according to the present embodiment includes a plurality of growth space sections  330  communicating with each other. 
     In more detail, each of the growth space sections  330  includes an inlet area  331  disposed on an associated surface of an anchor module body  310  and a communication area  350  connected to the inlet area  331 . 
     The inlet areas  331  of the growth space sections  330 , which are defined respectively in parallel on one of the sides of the anchor module body  310  and the other side facing the same, are in direct communication with each other through the associated communication areas  350 . In addition, the inlet areas  331  of the growth space sections  330 , which are defined respectively on one  312  of the sides of the anchor module body  310  and the other side  313  adjacent and perpendicular to the same, are in communication with each other through the associated communication areas  350  orthogonal to each other. 
     Each of the communication areas  350  has a cross-sectional size smaller than or equal to the associated inlet area  331 . In addition, the cross-sectional size of the communication area  350  is decreased as the distance from the inlet area  331  is increased. That is, the cross-sectional size of the communication area  350  is gradually decreased in a direction away from the inlet area  331 . Since the communication area  350  has different cross-sections in size at a portion adjacent to the inlet area  331  and a portion separated therefrom, it is possible to provide a space in which aquatic organisms can grow more stably. 
     Meanwhile, a frame section  340  is disposed in a portion of the anchor module body  310  in which the communication areas  350  are not defined, so as not to be exposed through the communication areas  350 . 
     Although the present embodiment describes that all of the growth space sections  330  are in communication with each other, the present disclosure may also include a configuration in which only some of the growth space sections  330  are in communication with each other. 
     According to the proposed embodiment, since the growth space sections  330  are in communication with each other so that aquatic organisms grow within the environment-friendly marine-farm-type mooring anchor module, it is possible to more stably maintain the growth environment. 
       FIG.  9    is a view illustrating a configuration of an overwater photovoltaic panel installation structure according to a further embodiment of the present disclosure. 
     The overwater photovoltaic panel installation structure according to the present embodiment has substantially the same configuration as that illustrated in  FIGS.  1  to  3   , except that there is a difference in the configuration for supplying air near the seabed where the mooring anchor module is installed and for sensing underwater conditions. Therefore, the main features of the present embodiment will be described below. 
     Referring to  FIG.  9   , the overwater photovoltaic panel installation structure, which is designated by reference numeral  1 , according to the present embodiment may monitor an underwater environment near the floor surface of the ocean where the environment-friendly marine-farm-type mooring anchor module is installed, so as to improve underwater environmental factors such as an amount of dissolved oxygen to be suitable for the growth of aquatic organisms. 
     In more detail, the overwater photovoltaic panel installation structure  1  according to the embodiment of the present disclosure further includes an air supply unit  163  disposed on the photovoltaic panel support assembly  110  and operated by power supplied from the photovoltaic panel  120 , a sensing unit  164  configured to measure an amount of oxygen in the water, a communication unit  162  configured to communicate with an external device such as the management device  500  and transmit information about the amount of oxygen in the water measured by the sensing unit  164  to the management device  500 , and a control unit  161  configured to control the air supply unit  163 , the sensing unit  164 , and the communication unit  162 . 
     Each growth space section  330  of the environment-friendly marine-farm-type mooring anchor module has a plurality of air supply holes  335  formed therein, and the anchor module body  310  has at least air flow hole to which the air supply holes  335  are connected. 
     The connection unit  400  includes a first conduit  410  formed inside the connection unit, and a second conduit  420  disposed in parallel with and independent of the first conduit  410 . 
     One end of the first conduit  410  is connected to the air supply unit  163  and the other end of the first conduit  410  communicates with the air flow hole of the anchor module body  310 , thereby enabling air to be supplied from the air supply unit  163  to the air flow hole. 
     A probe unit (not shown) connected to the sensing unit  164  is inserted at one side thereof into and moved in the second conduit  420 . When the probe unit is moved toward the mooring anchor module  300  in the state in which the probe unit is inserted into the second conduit  420 , the sensing unit  164  measures the amount of oxygen in the water near the floor surface of the ocean where the mooring anchor module  300  is disposed, so as to transmit information about the measured amount of oxygen to the control unit  161  and the management device  500 . 
     The control unit  161  controls the air supply unit  163  to supply air to the mooring anchor module, based on the information about the amount of oxygen, when the measured amount of oxygen in the water is smaller than a predetermined reference amount of oxygen. In this case, the reference amount of oxygen may vary with the season. 
     Meanwhile, the overwater photovoltaic panel installation structure  1  further includes a camera unit  380  installed in the mooring anchor module to capture an underwater ecological environment. The camera unit  380  may be, for example, an underwater camera capable of operating in an underwater environment. The camera unit  380  may be electrically connected to the sensing unit  164  or the control unit  161  through the second conduit  420  to transmit the captured image to the outside. 
     According to the proposed embodiment, it is possible to more stably maintain an aquatic ecosystem by easily measuring the amount of oxygen in the water near the floor surface of the ocean where the environment-friendly marine-farm-type mooring anchor module is installed, and by supplying air to the environment-friendly marine-farm-type mooring anchor module when the amount of oxygen in the water is insufficient. 
       FIG.  10    is a view illustrating a configuration of an environment-friendly marine-farm-type mooring anchor module according to still yet another further embodiment of the present disclosure. 
     The environment-friendly marine-farm-type mooring anchor module, which is designated by reference numeral  300 , according to the present embodiment has substantially the same configuration as that of the overwater photovoltaic panel installation structure illustrated in  FIGS.  1  to  3   , except for some configurations. Therefore, the main features of the present embodiment will be described below. 
     Referring to  FIG.  10   , the environment-friendly marine-farm-type mooring anchor module  300  according to the present embodiment includes a plurality of growth space sections  330 , each having a pattern part  350  formed on the surface thereof. The pattern part  350  includes a plurality of pattern members  351  protruding or recessed with respect to the surface of the growth space section  330 . 
     That is, it is possible to more easily settle aquatic organisms in the growth space section  330  since the pattern members  351  protrude or are recessed with respect to the surface of the growth space section  330 . Each of the pattern members  351  may have one or a combination of two or more of circular, rectangular, and linear shapes. 
     The environment-friendly marine-farm-type mooring anchor module  300  may include an anchor module body  310  having an anti-precipitation layer (not shown) formed on the surface thereof. The anti-precipitation layer may be at least one of a ceramic coating layer, an ocher coating layer, and a nanosilver coating layer. That is, when the environment-friendly marine-farm-type mooring anchor module  300  according to the embodiment of the present disclosure is made of, for example, a concrete material, the anti-precipitation layer may be further applied to the anchor module body  310  in order to suppress the precipitation of organic compounds that may affect the marine environment from the anchor module body  310  in the state in which the environment-friendly marine-farm-type mooring anchor module  300  is disposed in the ocean. 
       FIG.  11    is a view illustrating a configuration of an environment-friendly marine-farm-type mooring anchor module according to still yet another further embodiment of the present disclosure. 
     The environment-friendly marine-farm-type mooring anchor module, which is designated by reference numeral  300 , according to the present embodiment has substantially the same configuration as that illustrated in  FIG.  10   , except for some configurations. Therefore, the main features of the present embodiment will be described below. 
     Referring to  FIG.  11   , the environment-friendly marine-farm-type mooring anchor module  300  according to the present embodiment may include an anchor module body  310  and a plurality of growth space sections  330 . The anchor module body  310  may have a body-side pattern part formed in a remaining area thereof where the growth space sections  330  are not defined, the body-side pattern part including a plurality of body-side pattern members protruding or recessed with respect to the anchor module body  310 . That is, since the body-side pattern part is formed in an area other than the portion where the growth space sections  330  are defined, it is possible to more smoothly settle aquatic organisms in the environment-friendly marine-farm-type mooring anchor module  300 . 
     In this case, the pattern members  351  formed in each growth space section  330  may have different sizes or densities from the body-side pattern members. 
       FIG.  12    is a view illustrating a floating wind power system installation structure according yet another further embodiment of the present disclosure. 
     The floating wind power system installation structure according to the present embodiment has a different configuration from the overwater photovoltaic panel installation structure illustrated in  FIGS.  1  to  11   , except for the environment-friendly marine-farm-type mooring anchor module  300 .
