The base frame 20 includes a base frame 20, 20 and the foot frame 40 to be supported by the auxiliary frame 30.

The solar photovoltaic panel 10 is a module in which a plurality of solar cells are arrayed in a lattice form. A plurality of solar photovoltaic panels 10 are installed.

The column 15 is coupled to the base frame 20 to support the solar photovoltaic panel 10. The post 15 is formed at a constant height from the base frame 20. Since the solar photovoltaic panel 10 is inclined, the support for supporting the lower part of the solar photovoltaic panel 10 is formed to be lower in height than the support for supporting the upper part of the solar photovoltaic panel 10.

The support bracket 17 is used to engage the support 15 with the top of the base frame 20. The connection bracket 17 may be formed by bending a metal plate at a right angle. One side of the connection bracket 17 is coupled to the base frame 20 by a screw and the other side of the connection bracket 17 can be coupled to the support 15 by a screw.

Preferably, the coating layer 23 is formed of a material such as a synthetic resin such as polyethylene. Low density polyethylene (LDPE) may be applied to the surface of the base frame 20 with polyethylene to form the coating layer 23. The surface of the base frame 20 can be sandblasted before the coating.

When a coating layer 23 is formed by applying a synthetic resin such as polyethylene to the outer surface of the base frame 20, a coating layer is not formed on the inner surface of the base frame 20. Therefore, it is preferable to attach the sealing cap 25 to the end of the base frame 20 to prevent air or water from being introduced into the base frame 20. In order to maintain watertightness between the sealing cap 25 and the end portion of the base frame 20, a polyurea is applied in a state where the sealing cap 25 is coupled to the base frame 20, Thereby forming a coating part 27 for covering.

The auxiliary frame 30 is installed so as to intersect the base frame 20. A plurality of auxiliary frames 30 may be installed at regular intervals between the two base frames 20. The auxiliary frame 30 may be formed with an empty square pipe structure inside.

The auxiliary frame (30) is coupled to the base frame (20) by means of a connecting bracket (35). The connection bracket 35 may be formed by bending a metal plate at a right angle. One side of the connecting bracket 35 is coupled to the auxiliary frame 30 by a screw and the other side of the connecting bracket 35 can be coupled to the base frame 20 by a screw. In this case, the outer surface of the connection bracket 35 is coated with polyurea to prevent air or water from penetrating into the base frame 20 and the auxiliary frame 30 through the screw connection portion, do.

Although not shown, a coating layer made of a synthetic resin material such as polyethylene may be formed on the outer surface of the auxiliary frame 30 in the same manner as the base frame 20. Further, it is preferable to attach the sealing cap to the end portion of the auxiliary frame 30. [ It is of course possible to form a coating portion for covering the sealing cap by applying the polyurea in a state where the sealing cap is coupled to the auxiliary frame 30 for watertightness maintenance between the sealing cap and the end portion of the auxiliary frame 30. [

Since the base frame 20 and the auxiliary frame 30 do not receive air or water, the corrosion can be prevented.

 The foot part (40) is installed to be supported by the base frame (20) and the sub frame (30). The pedestal portion 40 may be made of synthetic resin, synthetic wood, metal, or the like.

Fixed piles (5) may be provided to fix the floating pagewh solar powered device of the present invention in a specific location. The stationary file 5 is fixed to the bottom of the water area where the floating type solar photovoltaic apparatus of the present invention is installed. The upper portion of the fixed file 5 is exposed above the water surface. The fixed file 5 may be coupled to the support plate 7 provided on the footrest 40 as shown in Fig. The support plate 7 is vertically movably coupled along the fixing pawls 5, so that the foot plate portion 40 can move up and down according to the water level fluctuation.

The float (50) can be formed of a synthetic resin material. The float 50 includes a float 51 which can float on the water surface and a supporting bracket 90 provided on the outer surface of the float 51 and to which the base frame 20 is coupled.

Support brackets (90) are provided on both left and right sides of the housing (53). The housing 53 is formed in a cylindrical structure in which the interior is empty. The inside of the housing (53) is sealed with air filled, and serves to impart buoyancy to the mouth.

The housing 53 may be formed by dividing into an upper housing and a lower housing, and then joining them by a heat fusion method.

The horizontal barrier ribs 73 and the vertical barrier ribs 75 divide the inside of the housing 53 into a plurality of spaces. Each space is formed independently. When a part of the housing 53 is broken due to such a split structure, the buoyancy is somewhat reduced, but it is possible to prevent the total buoyancy from being lost at once.

The support bracket 90 is formed so that the sub-assembly 51 can be easily separated from the base frame 20 when the sub-assembly 51 is pushed downward. The support bracket 90 has a structure in which an opening is formed upward.

The support bracket 90 may include a protruding member 93 protruding from the outer surface of the housing 53 and a protruding member 93 provided on the protruding member 93 and having an opening And a support portion 91 formed on the upper portion.

A coupling groove 55 is formed in the upper portion of the sub-hole 51 to which the pressing support 19 is coupled.

The pressure support 19 is installed between the supports 15. Both ends of the pressure support 19 are fixed to the inside of the opposed pillars 15, respectively.

In the illustrated example, two coupling grooves 55 are formed on the upper portion of the housing 51 in parallel. The coupling grooves 55 are formed at a constant depth. Since the pressing support 19 is coupled to the upper portion of the mouth 51, the bearing capacity of the mouth can be further increased.

The buoyancy chamber 70 has a hollow cylindrical housing 71 and a transverse bulkhead and a longitudinal bulkhead which are installed inside the housing 71 and divide the inside of the housing 71 into a plurality of spaces.

Support brackets 90 are provided on both left and right sides of the housing 71. The housing 71 is formed in a rectangular tubular structure with an empty interior. The inside of the housing (71) is sealed in the air filled state and serves to impart buoyancy to the mouth. On the upper portion of the housing, a coupling groove 75 to which the pressing support 19 is coupled is formed.

Although not shown, the horizontal partition wall and the vertical partition wall divide the interior of the housing 71 into a plurality of spaces. Each space is formed independently. This division structure is the same as the example of Fig. 7 described above.

A weight chamber 80 is formed in the lower portion of the buoyancy chamber 70. The weight chamber 80 may be integrally formed with the buoyancy chamber 70, or may be integrally formed by bonding them separately.

The weight chamber 80 includes a cylindrical body 81 having an inside and an open bottom and a cover 85 coupled to an open lower portion of the body 81. The weight chamber 80 includes a body 85, An inlet hole 86 formed in the cover 85 so as to allow the air to flow into the body 81 and a body 81 for discharging the air inside the body 81 when water flows into the inside of the body through the inlet hole 86. [ And a ventilation hole 83 formed in a side surface of the ventilation hole.

The body 81 has a rectangular tubular structure. The upper and lower portions of the body 81 have an open structure. Alternatively, the upper portion of the body 81 may be a closed structure. The upper portion of the body 81 is coupled to the lower portion of the housing 71. The body 81 and the housing 71 may be bonded together by a heat fusion bonding method or may be bonded together by an adhesive. Needless to say, they can be joined using a separate joining tool.

The cover 85 is formed in a rectangular plate shape. The cover 85 may be coupled with the bottom of the body 81 with a screw 89. To this end, the cover 85 may be formed with a plurality of insertion holes 87 into which screws are inserted.

The inlet hole 86 is formed in one or a plurality of covers. The water is introduced from the outside of the body 81 through the inlet hole 86 into the inside. The inlet hole 86 is formed in an appropriate size to facilitate the inflow of water.

When the water flows into the body 81 through the inflow hole 86, the air inside the body 81 is discharged to the outside through the vent hole 83. The vent holes 83 are formed on the upper side of the side surface of the body 81 at regular intervals.

When the water flows into the inside of the body 81, the weight of the water is added to the bowl 60 by the weight of the water. Accordingly, since the weight of the lower portion of the unit 60 is increased, the stability of the unit 60 can be improved and the swing of the unit 60 due to wind or wave can be greatly reduced. Thus, breakage and deformation of the base frame, the auxiliary frame and the support can be prevented in advance.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation.
