[0048] Preferred embodiments of a waterproof photovoltaic power generation device according to the present invention will be described in detail below with reference to the accompanying drawings. In describing the present invention below, if it is determined that a detailed description of known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description will be omitted. Throughout the specification, when a part is described as "comprising" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0049] A waterproof solar power generation device according to one embodiment of the present invention is described with reference to FIGS. 1 to 4. The waterproof solar power generation device comprises: a plurality of solar modules (1) that are connected to each other to form a plurality of rows and columns and produce electricity by solar energy; an inclined structure (2) that is inserted between the solar modules (1) to block the inflow of water and is formed along an inclined direction; and a horizontal structure (3) that is inserted between the solar modules (1) to block the inflow of water and is formed to intersect vertically with the inclined structure.

[0050] The present invention relates to a photovoltaic power generation device that can be applied to the roof of a building, a canopy, or various types of structures having a roof, and is designed to prevent water leakage by blocking water from entering between photovoltaic modules (1) and to improve usability. In particular, the waterproof photovoltaic power generation device can more effectively block water from entering the lower part of the photovoltaic power generation device by forming a passage through which water can be discharged in an inclined direction even in the event of leakage.

[0051] The above-described solar module (1) is configured to produce electricity by sunlight, and a conventional solar module formed such that multiple modules are connected in rows and columns may be applied. The above-described solar module (1) may be formed to be inclined toward one direction, and a side housing (11) may be formed on the side of each solar module (1) to block the perimeter of the solar module (1) and to allow an inclined structure (2) and a horizontal structure (3) to be fitted.

[0052] The above-mentioned side housing (11) is configured to surround the side of the solar module (1) and may include an upper ring (111) fitted to the top of the solar module (1) and a lower plate (112) protruding inward from the bottom, and an inclined structure (2) and a horizontal structure (3) are fitted into the upper ring (111) and the lower plate (112).

[0053] The above-mentioned inclined structure (2) is configured to be inserted between solar modules (1) to block the inflow of water and can be formed along the inclined direction of the solar modules (1). In other words, when the solar modules (1) are formed to be inclined in a vertical direction, the inclined structure (2) is also formed to be inclined in a vertical direction and can be formed between each of the multiple solar modules (1) formed in a horizontal direction. As shown in FIG. 2, the above-mentioned inclined structure (2) includes a pair of fastening parts (21) formed on both sides and fitted into the solar modules (1) on both sides; a support part (22) formed below the fastening parts (21) to which the pair of fastening parts (21) are joined; and a cover part (23) formed above the pair of fastening parts (21) to seal the top of the fastening parts (21).

[0054] The above-mentioned fastening part (21) is configured to be fitted onto the side of the solar module (1), and is formed as a pair on both sides so as to be fitted onto each of the solar modules (1) on both sides. More precisely, the above-mentioned fastening part (21) is fitted onto the side housing (11) of the solar module (1), and can be fitted onto the upper ring (111) and the lower plate (112) of the side housing (11), respectively. In particular, the above-mentioned fastening part (21) is covered by the cover part (23) while fitted onto the solar modules (1) on both sides so as to seal the space between the fastening part (21), and through a unique structure, water is prevented from flowing between the cover part (23) and the fastening part (21). To this end, the above-mentioned fastening part (21) may include a close fastening part (211), a lower fastening part (212), a side support part (213), and a repair edge (214).

[0055] The above-mentioned close-fitting member (211) is configured to be fitted onto the top of the solar module (1), so as to be fitted in close contact while covering the upper ring (111) of the solar module (1). To this end, the above-mentioned close-fitting member (211) is formed to protrude toward the solar module (1) from the upper part of the side support member (213), and its end is formed to be bent downward so as to be fitted onto the upper ring (111).

[0056] The lower fastening member (212) is configured to be fitted to the bottom of the solar module (1) and is fitted to the lower plate (112) of the solar module (1). Accordingly, the lower fastening member (212) is formed to protrude a certain length toward the solar module (1) from the bottom of the side support member (213) and is in close contact with the bottom of the lower plate (112), and its end is formed to be bent in a shape that wraps around the lower plate (112) so as to be fitted to the lower plate (112).

[0057] The above-mentioned side support member (213) is configured to be supported in close contact with the side of the solar module (1), or more precisely, to be supported in close contact with the side housing (11).

[0058] The repair edge (214) is configured to extend and protrude a certain length upward from the side support member (213), and can be formed by extending a certain length upward from the point where the close fastening member (211) protrudes. Accordingly, the repair edge (214) prevents water from entering the space between the fastening members (21) even when water enters through the gap between the cover member (23) and the close fastening member (211), and allows water to flow along the slope direction before it fills up to the height of the repair edge (214), thereby enabling effective waterproofing. In addition, the repair edge (214) is configured to form a protruding close-fitting member (214a) that protrudes inward from its upper end, thereby widening the area in contact with the cover member (23) and making it more effective to prevent water from entering between the cover member (23) and the fastening member (21).

[0059] The support member (22) is formed on the lower side of the fastening member (21) and is configured to combine a pair of fastening members (21), thereby allowing the side housing (11), the fastening member (21), and the support member (22) to be combined while the fastening member (21) is fitted into the side housing (11) of the solar module (1). In particular, the support member (22) forms a passage through which water can flow along the inclined direction when water enters through the gap even when the solar modules (1) are sealed, thereby preventing water from entering the lower side of the solar power generation device. To this end, the support member (22) may include a first waterway groove (221), a second waterway groove (222), and a fixing means (223).

[0060] The first channel groove (221) is formed on the central side of the support part (22) to form a passage for water flow, and is formed to be recessed to a certain depth from the top. A void space is formed between the fastening parts (21) on both sides, into which the fastening screw (232a) of the cover part (23), which will be described later, is inserted and fixed. When water flows in through the gap where the fastening screw (232a) is inserted, it flows out along the inclined direction through the first channel groove (221). Additionally, the fastening screw (232a) can be caught and fixed in the first channel groove (221). To this end, a catch portion (221a) protruding inward is formed so that the head (232a-1) of the fastening screw (232a) can be caught. Thus, the installation and fixing of the inclined structure (2) can be easily accomplished.

[0061] The second channel groove (222) is configured to be recessed to a certain depth on the outer side of the point where it is in close contact with the lower fastening member (212), thereby forming a passage for water flow and allowing it to be discharged outward along the inclined direction even when water flows into the gap between the solar module (1) and the fastening member (21). The inclined structure (2) is designed to fill the space between the solar modules (1) in a sealed state to block the inflow of water, but since water may flow in finely through the gap due to prolonged use, a passage for water discharge can be additionally formed through the second channel groove (222) to completely block water from falling to the lower side of the solar module (1). Additionally, the second channel groove (222) may additionally include a barrier wall (222a) formed to protrude a certain height higher than the position where it is in close contact with the lower fastening member (212) on the outer side, thereby more effectively blocking the water in the second channel groove (222) from overflowing outward.

[0062] The above fixing means (223) is configured to fix the solar module (1), the fastening part (21), and the support part (22) by combining them, and can be formed in the shape of a screw, nut, etc., so as to be fastened by penetrating the side housing (11) of the solar module (1), the lower fastening end (212) of the fastening part (21), and the support part (22).

[0063] The above cover portion (23) is configured to be coupled to the upper side of the pair of fastening portions (21) to seal the upper end of the fastening portions (21), thereby sealing the space between the fastening portions (21) on both sides to block the inflow of water and allowing the fastening portions (21) to be fixed in close contact with the solar module (1). To this end, the above cover portion (23) may include a sealing cover (231) and a fastening means (232).

[0064] The sealing cover (231) is configured to be in close contact with the upper ends of the two connecting parts (21) to seal the space between the connecting parts (21), and it is preferable that it be in close contact with the upper end of the repair edge (214) to minimize the inflow of water into the space between the repair edge (214) and the sealing cover (231). Additionally, the sealing cover (231) is configured so that its end is in close contact with the upper end of the connecting connecting part (211) to minimize the inflow of water between the connecting connecting part (211) and the sealing cover (231). The sealing cover (231) is configured to maintain a fixed state by fastening the connecting means (232) while in close contact with the repair edge (214) and the connecting connecting part (211). Additionally, the sealing cover (231) may include a close-fitting folded end (231a) formed to be folded at its end to increase the contact area with the close-fitting fastening end (211), thereby enabling stable connection of the sealing cover (231) and effective blocking of water inflow.

[0065] The above fastening means (232) is configured to fix the inclined structure (2) to the solar module (1) and may include a fastening screw (232a) and a fixing nut (232b).

[0066] The above fastening screw (232a) is inserted through the sealing cover (231) and is inserted through the space between the two fastening parts (21) and supported by the lower support part (22). To this end, the head (232a-1) protruding outward from the end of the fastening screw (232a) can be inserted into the first channel groove (221) of the support part (22) and is supported by being caught on the catch end (221a) of the first channel groove (221). Therefore, by inserting and fastening the fastening screw (232a), the support part (22), the fastening part (21), and the cover part (23) can be pulled to maintain a state of close contact with the side housing (11) of the solar module (1), thereby enabling simple installation, stable fixation, and effective waterproofing.

[0067] The above fixing nut (232b) is configured to be inserted into and fastened to the fastening screw (232a), and can be fixed in a state of close contact with the upper part of the sealing cover (231) to maintain the fastening state of the fastening screw (232a).

[0068] The horizontal structure (3) is configured to be inserted between solar modules (1) to block the inflow of water, and is formed to intersect vertically with the inclined structure (2). In particular, since the horizontal structure (3) is formed to be perpendicular to the inclined direction of the solar module (1), it has a unique structure that prevents water flowing along the solar module (1) from entering, and can be formed between each solar module (1) formed in the vertical direction. As shown in FIG. 3, the horizontal structure (3) includes a first fixing part (31) formed to be fitted into the lower solar module (1'); a second fixing part (32) formed to be fitted into the upper solar module (1''); and a connecting part (33) formed on the lower side of the first fixing part (31) and the second fixing part (32) to be connected.

[0069] The first fixing part (31) is configured to be fitted into the lower solar module (1') formed in the inclined lower direction, and is fitted into the side housing (11') of the lower solar module (1'), and can be fitted into the upper ring (111') and lower plate (112') of the side housing (11'), respectively. In particular, the first fixing part (31) can be covered by the second fixing part (32) while fitted into the lower solar module (1') to minimize the inflow of water flowing along the inclined solar module (1), and furthermore, through a unique structure, the inflow of water between it and the second fixing part (32) can be further reduced. To this end, the first fixing part (31) may include a protruding fastening part (311), a bottom fastening part (312), a side contact part (313), a protruding part (314), a contact gasket (315), and a permeable channel (316).

[0070] The above-mentioned protruding fastening member (311) is configured to be fitted onto the upper part of the lower solar module (1'), so as to be fitted in close contact while covering the upper ring (111'). To this end, the above-mentioned protruding fastening member (311) is formed to protrude toward the lower solar module (1') from the upper part of the side contact member (313), and its end is formed to be bent downward so as to be fitted onto the upper ring (111').

[0071] The above-mentioned bottom fastening member (312) is configured to be fitted into the bottom of the lower solar module (1') and fitted into the lower plate (112'). Accordingly, the above-mentioned bottom fastening member (312) is formed to protrude a certain length from the bottom of the side contact member (313) toward the lower solar module (1') and is in close contact with the bottom of the lower plate (112'), and its end is formed to be bent in a shape that wraps around the lower plate (112') so as to be fitted into the lower plate (112').

[0072] The above-mentioned side contact portion (313) is configured to be supported by being in close contact with the side of the lower solar module (1'), or more precisely, to be supported by being in close contact with the side housing (11').

[0073] The above-mentioned protruding end (314) is configured to protrude toward the second fixing part (32) from the upper part of the side contact end (313), and a gasket insertion groove (314a) is formed to a certain depth in the upper part so that a sealing gasket (315) is inserted and fixed. The above-mentioned protruding end (314) can be made to be in close contact with the lateral contact end (324) of the second fixing part (32) to be described later, thereby minimizing the inflow of water.

[0074] The above-mentioned sealing gasket (315) is configured to be inserted into and fixed in the gasket insertion groove (314a), and is formed of an elastic material so as to be fitted into the gasket insertion groove (314a). In particular, the above-mentioned sealing gasket (315) can be fitted so as to be in close contact with the upper second fixing part (32), thereby further reducing the inflow of water between the first fixing part (31) and the second fixing part (32). The lower covering part (322), which will be described later, of the second fixing part (32) is in close contact with the upper side of the protruding fastening part (311) of the first fixing part (31) to block the inflow of water, but since water may still flow in through the gap, the space between the first fixing part (31) and the second fixing part (32) is sealed with the sealing gasket (315) to further reduce the inflow of water.

[0075] The above-mentioned permeable channel (316) is a space formed between the first fixed part (31) and the second fixed part (32), and is designed to form a space through which water can flow by ensuring that the side contact section (313) and the side contact section (324) are spaced apart at a certain distance. As described above, the horizontal structure (3) blocks the inflow of water through the structure and contact of the first fixed part (31) and the second fixed part (32) and the formation of the contact gasket (315); however, if used for a long time, a small amount of water may continue to flow in. Therefore, the horizontal structure (3) forms a permeable channel (316) to allow water to flow, thereby ensuring that the water is discharged into the external space before it flows out to the lower side.

[0076] The second fixing part (32) is configured to be fitted onto the upper solar module (1''), and specifically, while fitted onto the upper solar module (1''), it covers the first fixing part (31) to block water flowing along the inclined direction from entering between the solar modules (1). To this end, the second fixing part (32) may include an upper fastening part (321), a lower covering part (322), a bottom bending part (323), and a side contact part (324).

[0077] The upper fastening member (321) is configured to be fitted onto the upper part of the upper solar module (1''), and is fitted in close contact with the upper ring (111'') while covering it, similar to the protruding fastening member (311). To this end, the upper fastening member (321) is formed to protrude toward the upper solar module (1'') from the upper part of the lateral contact member (324), and its end is formed to be bent downward so as to be fitted onto the upper ring (111'').

[0078] The above-mentioned lower covering member (322) is configured to protrude to the opposite side of the upper fastening member (321) and cover the upper part of the protruding fastening member (311) of the first fixing member (31), thereby ensuring close contact with the protruding fastening member (311). Accordingly, water flowing along the inclination direction of the solar module (1) is difficult to enter between the first fixing member (31) and the second fixing member (32), thereby enabling effective waterproofing.

[0079] The bottom bending section (323) is configured to be fitted into the bottom of the upper solar module (1'') and fitted into the lower plate (112''). Accordingly, the bottom bending section (323) is formed to protrude a certain length from the bottom of the lateral contact section (324) toward the upper solar module (1'') and is in close contact with the bottom of the lower plate (112''), and its end is formed to be bent in a shape that wraps around the lower plate (112'') so as to be fitted into the lower plate (112'').

[0080] The above-mentioned lateral contact portion (324) is configured to be supported by being in close contact with the side of the upper solar module (1''), or more precisely, to be supported by being in close contact with the side housing (11'').

[0081] The above-mentioned connecting part (33) is formed on the lower side of the first fixing part (31) and the second fixing part (32) and is configured to be connected to the first fixing part (31) and the second fixing part (32). The bottom fastening part (312) and the bottom bending part (323) are each fitted into the lower plate (112'') of the side housing (11''), thereby connecting the side housing (11''), the bottom fastening part (312), the bottom bending part (323), and the connecting part (33). In particular, the above-mentioned connecting part (33) forms a passage through which water can flow when water enters through the gap even when sealed between the solar modules (1), thereby preventing water from entering the lower side of the solar power generation device. To this end, the above-mentioned connecting part (33) may include a waterway groove (331) and a connecting means (332).

[0082] The above-mentioned waterway groove (331) is formed to be recessed to a certain depth on both sides of the connecting part (33) to form a passage for water to flow, and can be formed on the outer side of the point in close contact with the bottom fastening part (312) and the bottom bending part (323). Therefore, even if water flows into the gap between the first fixing part (31) or the second fixing part (32) and the solar module (1), the water can be discharged to the outside through the waterway groove (331) to more effectively block the inflow of water. However, since the above-mentioned horizontal structure (3) is formed along an inclined direction and is formed inclined from the second fixing part (32) toward the first fixing part (31), the waterway groove (331) may be formed only on the side of the first fixing part (31) as shown in FIG. 4. Additionally, the above-mentioned channel groove (331) may further include a protruding wall (331a) formed to protrude a certain height higher than the position where it is in close contact with the bottom fastening member (312) or the bottom bending member (323) on the outside, thereby allowing the water in the channel groove (331) to more effectively block overflow to the outside.

[0083] The above coupling means (332) is configured to combine and fix the solar module (1), the first fixing part (31), and the second fixing part (32), and is formed in the shape of a screw, nut, etc., so that the lower solar module (1') and the first fixing part (31), and the upper solar module (1'') and the second fixing part (32) are each coupled to the coupling part (33).

[0084] Although the applicant has described various embodiments of the present invention above, such embodiments are merely examples of implementing the technical concept of the present invention, and any modification or alteration that implements the technical concept of the present invention should be interpreted as falling within the scope of the present invention.
