DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application. In the description of the present application, if a component has a central axis or a hollow chamber, the "inside" of the component refers to the side of the component close to the central axis of the component or arranged inside the hollow chamber; the "outside" of the component refers to the side of the component away from the central axis of the component.

[0027] One aspect of the present application provides a Figure 1 The photovoltaic building integrated system 100 shown in the figure includes a photovoltaic module 11 and a photovoltaic module mounting structure 12. The photovoltaic module 11 is connected to the photovoltaic module mounting structure 12, and the photovoltaic module mounting structure 12 is connected to a building (specifically, connected to the building structure such as the roof purlin or facade of the building). Specifically, the photovoltaic module 11 in the present application is a frameless photovoltaic module. Through the above-mentioned arrangement, the photovoltaic module 11, the photovoltaic module mounting structure 12 and the outer surface of the building are firmly connected to each other and form a unified whole, which greatly improves the overall stability and safety of the entire photovoltaic building integrated system 100. Figure 2As shown, the photovoltaic module mounting structure 12 includes a water channel 121 and a pressing block 122. The water channel 121 extends substantially along the direction of the first straight line 101. The pressing blocks 122 are arranged at intervals along the direction of the first straight line 101 and are disposed above the water channel 121. The photovoltaic module mounting structure 12 of the present application includes a plurality of water channels 121 parallel to each other, each water channel 121 is provided with a plurality of pressing blocks 122, and the two long sides of the photovoltaic module 11 are respectively placed on two adjacent water channels 121 and fixed to the water channels 121 through corresponding pressing blocks 122. The water channel 121 includes a channel top plate 1211 and a channel bottom 1212 extending in the direction of the first straight line 101. The channel top plate 1211 is located at the top of the water channel 121, and the channel bottom 1212 is located at the bottom of the water channel 121. The channel top plate 1211 is used to connect and fix the pressing block 122. At the same time, the channel top plate 1211 and the pressing block 122 cooperate with each other to form a fixed structure for fixing the photovoltaic module 11. The water channel 121 also includes channel walls 1213 located on both sides, and the channel walls 1213 are used to connect the channel top plate 1211 and the channel bottom 1212. The channel top plate 1211, the channel bottom 1212 and the channel wall 1213 can cooperate with each other to form a complete water channel 121, which plays a role in guiding the water flow in the photovoltaic building integrated system 100. The pressing block 122 is detachably connected to the channel top plate 1211. At least one side of the pressing block 122 is provided with an extension portion 1221, and a mounting groove is formed between the extension portion 1221 and the groove top plate 1211. The edge of the photovoltaic module 11 can be placed and fixed in the mounting groove, and the mounting groove can achieve good fixation of the photovoltaic module 11. Preferably, one side of the long side of the photovoltaic module 11 is set in the mounting groove.

[0028] As an optional implementation, Figure 3 As shown, the groove top plate 1211 at the top of the water guide groove 121 is provided with a first connection portion 1214, and the pressing block 122 is provided with a second connection portion 1222. Specifically, the first connection portion 1214 is provided at the top of the groove top plate 1211, and the second connection portion 1222 is provided at the bottom of the pressing block, and the second connection portion 1222 is snapped into the first connection portion 1214. A structure that can be connected to each other is provided between the water guide groove 121 and the pressing block 122, which can provide a guiding effect for the connection between the water guide groove 121 and the pressing block 122, and can facilitate the determination of the position between the water guide groove 121 and the pressing block 122, and can also improve the connection stability between the water guide groove 121 and the pressing block 122.

[0029] As an optional implementation, Figure 4As shown, the groove top plate 1211 is provided with a first fastening hole 1215, and the pressing block 122 is provided with a second fastening hole 1223. The groove top plate 1211 and the pressing block 122 are fixedly connected by fasteners 123 passing through the first fastening hole 1215 and the second fastening hole 1223. Through holes for fastening are respectively provided above the groove top plate 1211 and the pressing block 122 above the water guide groove 121. The water guide groove 121 and the pressing block 122 are connected by fasteners 123, which can play a good fixing role on the photovoltaic module 11. At the same time, the use of fasteners 123 for fixing can also provide the convenience of adjusting the height of the installation groove between the groove top plate 1211 of the water guide groove 121 and the extension 1221 of the pressing block 122, and the height of the installation groove can be conveniently adjusted, so that the photovoltaic module installation structure 12 in the present application can have a wider range of applicability and can be applicable to photovoltaic modules 11 of various thicknesses.

[0030] As an optional implementation, Figure 5As shown, the photovoltaic module mounting structure 12 further includes a first buffer 124 and a second buffer 125. The top of the groove top plate 1211 is provided with a first snap-in groove 1214, and the bottom of the extension 1221 is provided with a second snap-in groove 1224. The first buffer 124 is snap-fitted to the first snap-in groove 1214, and the second buffer 125 is snap-fitted to the second snap-in groove 1224. The photovoltaic module mounting structure 12 in the present application is mainly used to connect and fix the frameless photovoltaic module 11. The water guide groove 121 and the pressing block 122 in the present application that are in contact with the frameless photovoltaic module 11 are usually made of metal. The frameless photovoltaic module 11 is in direct contact with the water channel 121 and the pressing block 122. Firstly, the photovoltaic module 11 may be damaged due to the mutual squeezing effect, and may even cause the cell in the photovoltaic module 11 to split or crack, resulting in a reduction in the power of the photovoltaic module 11; secondly, the frameless photovoltaic module 11, the water channel 121 and the pressing block 122 may have metal contact, which may also cause short circuits. The first buffer 124 and the second buffer 125 are arranged at the corresponding positions of the groove top plate 1211 and the extension 1221, which can play a buffering and protective role between the photovoltaic module mounting structure 12 and the photovoltaic module 11, avoiding damage to the photovoltaic module 11, cell splitting or cracking, and possible short circuit problems caused by metal contact between the photovoltaic module 11, the water channel 121 and the pressing block 122, ensuring the power of the photovoltaic module 11, and improving the reliability and service life of the photovoltaic module 11 and the entire photovoltaic building integrated system 100. The first clamping groove 1214 and the second clamping groove 1224 are respectively arranged at the top of the slot top plate 1211 and the bottom of the extension part, which can better fix the first buffer 124 and the second buffer 125 and prevent the first buffer 124 and the second buffer 125 from displacement. At the same time, the mutually clamping structure can also increase the convenience of installation and replacement of the first buffer 124 and the second buffer 125, and reduce the installation difficulty, installation cost and later maintenance cost.

[0031] As an optional embodiment, the first buffer 124 is made of EPDM rubber, and the second buffer 125 is made of EPDM rubber. EPDM rubber has good elasticity and can play a good buffering role in the water channel 121 / pressing block 122 and the frameless photovoltaic module 11 in the present application, and can reduce the possibility of hidden cracks due to direct contact between the frameless photovoltaic module 11 and the water channel 121 / pressing block 122, and reduce the reduction of power generation caused by hidden cracks in the frameless photovoltaic module 11. At the same time, EPDM rubber also has better low-temperature performance. EPDM rubber can still maintain this good elasticity at low temperatures. The use of EPDM rubber can expand the temperature range of the photovoltaic module installation structure 12 and the photovoltaic building integrated system 100 of the present application. In addition, EPDM rubber also has good aging resistance and corrosion resistance. The use of EPDM rubber as a buffer can improve the overall service life of the photovoltaic module installation structure 12 and the photovoltaic building integrated system 100 of the present application.

[0032] As an optional embodiment, the width of the pressing block 122 is smaller than the width of the water guide 121. In the present application, for the water guide 121, on the one hand, the water guide 121 is used to guide the flow of water such as rainwater in the photovoltaic building integrated system 100, and guide the water flow to the outside of the photovoltaic building integrated system 100 to avoid problems such as leakage or corrosion caused by water accumulation. On the other hand, the water guide 121 is also used to carry the photovoltaic module 11. Therefore, the water guide 121 needs to have a relatively wide width to meet the functions of water guiding and bearing. The pressing block 122 basically only needs to realize the function of fixing the photovoltaic module 11 to the water guide 121. When the fixing function can be achieved, the width of the pressing block 122 can be appropriately reduced, which can not only save materials and reduce costs, but also reduce the weight of the entire photovoltaic module mounting structure 12.

[0033] As an optional embodiment, the pressing block 122 includes: Figure 2 The edge pressing block shown in the figure has only one extension 1221, and a single-sided mounting groove is formed between the extension 1221 and the groove top plate 1221, and the single-sided mounting groove is used to place the photovoltaic components on the edge. For the water guide grooves 121 arranged on both sides of the photovoltaic component mounting structure 12, because it is only necessary to carry the photovoltaic component 11 on one side, the groove top plate 1211 of the water guide groove 121 at this position can be asymmetrically arranged, and the groove top plate 1211 can only be provided with a structure that cooperates with the pressing block 122 on one side. Similarly, for the edge pressing blocks arranged on both sides of the photovoltaic component mounting structure 12, because it is also only necessary to fix the photovoltaic component 11 on one side, the edge pressing blocks arranged at this position only need to be provided with an extension 1221 that cooperates with the groove top plate 1211 on one side. The extension 1221 and the groove top plate 1211 cooperate with each other to form a single-sided mounting groove only on one side of the water guide groove 121.

[0034] As an optional embodiment, the pressing block 122 includes: Figure 6 The middle pressure block shown in the figure has two extensions 1221 located on both sides, and mounting grooves located on both sides are formed between the two extensions 1221 and the groove top plate 1211, and the mounting grooves on both sides are used to place the photovoltaic modules on both sides. For the water guide groove 121 set in the middle position of the photovoltaic module mounting structure 12, since it is necessary to carry and fix the photovoltaic modules 11 on both sides, the groove top plate 1211 of the water guide groove 121 set in the middle position is symmetrically arranged, and both sides of the groove top plate 1211 need to be provided with a structure that can cooperate with the extension 1221. Similarly, for the middle pressure block set in the middle position of the photovoltaic module mounting structure 12, since it is necessary to fix the photovoltaic modules 11 on both sides, the middle pressure block set in this position needs to be provided with extensions 1221 on both sides that cooperate with the groove top plate 1211. The extensions 1221 on both sides and the groove top plate 1211 cooperate with each other, and mounting grooves are formed on both sides of the water guide groove 121.

[0035] As an optional implementation, Figure 7 As shown, the photovoltaic assembly mounting structure 12 also includes an assembly support 126 extending in the direction of the second straight line 102, and the assembly support 126 is connected to at least one side of the water guide groove 121, and the assembly support 126 and the groove top plate 1211 of the water guide groove 121 constitute a bearing surface for bearing the photovoltaic assembly 11. In the photovoltaic assembly mounting structure 12 of the present application, the assembly support 126 can cooperate with the water guide groove 121 to play the role of bearing the photovoltaic assembly 11. The water guide groove 121 bears the long side of the photovoltaic assembly 11 extending in the direction of the first straight line 101, and the assembly support 126 bears the short side of the photovoltaic assembly 11 extending in the direction of the second straight line 102. The assembly support 126 and the groove top plate 1211 of the water guide groove 121 can form a bearing surface, and the photovoltaic assembly 11 is placed on the bearing surface, and the bearing surface serves the purpose of bearing and supporting the photovoltaic assembly 11. Generally speaking, the photovoltaic module 11 is generally rectangular, so from a top view, the first straight line 101 and the second straight line 102 are substantially perpendicular to each other, that is, the water channel 121 and the module support 126 are substantially perpendicular to each other (e.g. Figure 1As shown). However, with the development of diversified shapes of photovoltaic components 11 (for example, photovoltaic components 11 of diamond shapes etc. may be adopted), the angle between the first straight line 101 and the second straight line 102 can also be any angle when viewed from a top view. Similarly, for the water guide groove 121 arranged on the side of the photovoltaic component mounting structure 12, the component support 126 is only arranged on the inner side thereof. For the water guide groove 121 arranged in the middle position of the photovoltaic component mounting structure 12, it is necessary to arrange component support members 126 on both sides thereof. Specifically, the component support member 126 and the water guide groove 121 can be connected by welding, and the component support member 126 is welded to the side of the water guide groove 121, and the component support member 126 is basically in a level state with the top of the water guide groove 121.

[0036] As an optional implementation, Figure 8 As shown, the photovoltaic module mounting structure 12 also includes a sealing component 127. The sealing component 127 is disposed at at least one location between the extension portion 1221 and the photovoltaic module 11 or between adjacent photovoltaic modules 11. The sealing component 127 can prevent rainwater and the like from flowing in from the position where the extension portion 1221 contacts the photovoltaic module 11 or the position where the adjacent photovoltaic modules 11 contact, thereby improving the waterproof performance of the corresponding position, and at the same time ensuring that rainwater and the like can be guided to the outside of the photovoltaic building integrated system 100 through the water guide groove 121 to the greatest extent. Specifically, the sealing component 127 can be a pre-fabricated sealing strip or other structure that is attached to the corresponding position during construction, or the sealing component 127 can be formed by directly applying or filling the corresponding position with the corresponding glue material during construction and then curing it.

[0037] As an optional implementation, Figure 8 and Fig. 9As shown, the sealing assembly 127 includes a first sealing member 1271 extending in the direction of the first straight line 101 and a second sealing member 1272 extending in the direction of the second straight line 102. The first sealing member 1271 is arranged between the extension portion 1221 and the photovoltaic assembly 11, and the second sealing member 1272 is arranged above the assembly support member 126 and the second sealing member 1272 is arranged between adjacent photovoltaic assemblies 11. The first sealing member 1271 can seal the gap between the extension portion 1221 and the photovoltaic assembly 11 to prevent rainwater and the like from entering the photovoltaic assembly 11 and other structures through the gap between the extension portion 1221 and the photovoltaic assembly 11. The second sealing member 1272 can seal the gap between adjacent photovoltaic assemblies 11 to prevent rainwater and the like from entering the photovoltaic assembly 11 and other structures through the gap between adjacent photovoltaic assemblies 11. The first sealing member 1271 and the second sealing member 1272 can be pre-made sealing strips and other structures and attached to corresponding positions during construction. The sealing assembly 127 can also be formed by directly applying or filling a gelatinous material to a corresponding position during construction and then curing it. Specifically, the first seal 1271 and the second seal 1272 can be formed by directly applying or filling silicone glue to the corresponding positions during construction and curing. In addition, for other places in the photovoltaic module installation structure 12 of the present application that need waterproofing, such as fasteners, etc., a sealing structure can also be set in a similar way to apply or fill silicone glue.

[0038] As an optional implementation, Fig. 9 As shown, the photovoltaic module mounting structure 12 also includes a roof support 128 connected to the surface of the building, and the bottom of the water channel 121 is connected to the top of the roof support 128. The water channel 121 and the roof support 128 are connected together by welding. By connecting by welding, it is possible to avoid operations such as drilling holes on the water channel 121, ensure the integrity of the water channel 121, reduce the risk of water leakage in the water channel 121, and improve the efficiency of the water channel 121 in guiding water flow. The roof support 128 also provides a transition structure for connecting the water channel 121 to the surface of the building. If there is no roof support 128 as a transition structure, the water channel 121 may need to be connected to the surface of the building by fasteners after drilling holes, which will damage the integrity of the water channel 121 and may cause water leakage in the water channel 121. At the same time, if there is no roof support 128 as a transition gutter 121 close to the building surface, rainwater may accumulate between the gutter 121 and the building surface, causing erosion and other hazards to the building and the entire photovoltaic building integrated system 100.
