DETAILED DESCRIPTION

[0057] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0058] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the embodiments of the present application, "one or more" refers to one, two or more; "and / or" describes the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship.

[0059] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0060] The "multiple" in the embodiments of the present application refers to greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first" and "second" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0061] The terms "parallel" and "perpendicular" in this application refer to "substantially parallel" and "substantially perpendicular" in actual operation. "Substantially parallel" can be understood as parallel with a certain error, and similarly, "substantially perpendicular" can be understood as perpendicular with a certain error.

[0062] like Figure 1 and Figure 2 As shown, in a photovoltaic system, photovoltaic modules 01 are mounted on a mounting surface, such as the ground, a roof, or a floating structure, using photovoltaic brackets 02. Photovoltaic brackets 02 include support columns 023, crossbeams 024 secured to support columns 023, and longitudinal beams 025 secured to crossbeams 024. Crossbeams 024 and longitudinal beams 025 are arranged in a crosswise arrangement, and photovoltaic modules 01 are secured to longitudinal beams 025.

[0063] In order to ensure waterproof performance, the photovoltaic support 02 further includes a horizontal water trough 021 and a vertical water trough 022. In the case where the installation surface is a roof surface, the roof surface may also be provided with a vertical gutter 03 and a horizontal gutter 04.

[0064] In the above structure, the horizontal water trough 021 and the longitudinal water trough 022 will cause the structure and installation of the entire photovoltaic bracket 02 to be more complicated, affecting the construction efficiency of the photovoltaic system.

[0065] In addition, the transverse water trough 021 and the crossbeam 024 can be an integrated structure, i.e., a load-bearing water trough. Due to the notch in the load-bearing water trough, its mechanical properties, such as strength, are inferior to those of the crossbeam 024. During use, the load-bearing water trough may experience significant bending deformation and overflow, resulting in lower structural safety and poor waterproof reliability of the entire photovoltaic rack.

[0066] In order to solve the above problems, an embodiment of the present application provides a photovoltaic system waterproof structure.

[0067] like Figure 3 and Figure 13 As shown, the photovoltaic system waterproof structure provided in the embodiment of the present application includes: a photovoltaic bracket 2, and a photovoltaic component 1 fixed to the photovoltaic bracket 2; wherein, at least two photovoltaic components 1 are distributed in sequence along the horizontal direction, and at least two photovoltaic components 1 are distributed in sequence along the vertical direction.

[0068] like Figure 5 、 Figure 6 、 Figure 14 and Figure 15As shown, the first transverse end 11 of the photovoltaic module 1 is higher than the second transverse end 12 of the photovoltaic module 1, and the first transverse end 11 and the second transverse end 12 are arranged in sequence along the transverse direction. It can be understood that the transverse direction of the photovoltaic module 1 is tilted relative to the horizontal plane, so that rainwater can flow from a high point to a low point along the transverse direction of the photovoltaic module 1.

[0069] In two laterally adjacent photovoltaic modules 1, the second transverse end 12 of one overlaps the first transverse end 11 of the other. This creates an overlapping projection (across the thickness of the modules) of the two laterally adjacent photovoltaic modules 1, ensuring that water can flow laterally from one module 1 to the other. This overlapping portion prevents rainwater from seeping through the bottom surfaces of the modules 1 and causing leakage, eliminating the need for longitudinal water gutters.

[0070] It should be noted that the horizontal direction is parallel to the maximum panel surface of the photovoltaic module 1. Among two photovoltaic modules 1 adjacent in the horizontal direction, the horizontal second end 12 of the higher one is stacked on top of the horizontal first end 11 of the lower one. There may be a gap between the horizontal second end 12 of the higher one and the horizontal first end 11 of the lower one, which can be understood as: there is a gap between the two photovoltaic modules 1 adjacent in the horizontal direction; there may also be no gap between the horizontal second end 12 of the higher one and the horizontal first end 11 of the lower one, which can be understood as: the horizontal second end 12 of the higher one is in contact with the horizontal first end 11 of the lower one, which can also be understood as: the two photovoltaic modules 1 adjacent in the horizontal direction are in contact.

[0071] Combine Figure 3 、 Figure 5 、 Figure 6 、 Figure 13 、 Figure 14 and Figure 15 As shown, in two laterally adjacent photovoltaic modules 1, water on the higher one flows from the higher one's first lateral end 11 to the higher one's second lateral end 12, and then flows from the higher one's second lateral end 12 to the lower one's first lateral end 11, and then flows from the lower one's first lateral end 11 to the lower one's second lateral end 12, and so on. The water on the photovoltaic module 1 eventually flows to the lower lateral end 12 of the photovoltaic module 1 at the lowest position and then flows to the set position (such as the first drainage channel 3 mentioned below). Therefore, all photovoltaic modules distributed in sequence in the laterally direction form a diversion structure, and there is no need to set up a separate transverse water trough.

[0072] It should be noted that Figure 3 and Figure 13 In FIG, the single arrow straight line indicates the approximate flow direction of water on the photovoltaic module 1.

[0073] like Figure 10 and Figure 20 As shown, the first longitudinal end 13 of the photovoltaic module 1 is higher than the second longitudinal end 14 of the photovoltaic module 1, and the first longitudinal end 13 and the second longitudinal end 14 are arranged in sequence along the longitudinal direction. This can be understood as follows: the longitudinal direction of the photovoltaic module 1 is tilted relative to the horizontal plane, so that rainwater can flow from a high point to a low point along the longitudinal direction of the photovoltaic module 1.

[0074] In two longitudinally adjacent photovoltaic modules 1, the longitudinal second end 14 of one overlaps the longitudinal first end 13 of the other. This creates an overlap between the projections of the two longitudinally adjacent photovoltaic modules 1 (projections along the thickness of the photovoltaic modules 1), ensuring that water can flow longitudinally from one photovoltaic module 1 to the other. This overlap prevents rainwater from seeping onto the bottom surfaces of the photovoltaic modules 1 and causing leakage, eliminating the need for horizontal water gutters.

[0075] It should be noted that, of two longitudinally adjacent photovoltaic modules 1, the longitudinal second end 14 of the taller one is stacked on top of the longitudinal first end 13 of the shorter one. There may be a gap between the taller one's longitudinal second end 14 and the shorter one's longitudinal first end 13, which can be understood as: there is a gap between the two longitudinally adjacent photovoltaic modules 1; there may also be no gap between the taller one's longitudinal second end 14 and the shorter one's longitudinal first end 13, which can be understood as: the taller one's longitudinal second end 14 and the shorter one's longitudinal first end 13 are in contact, which can also be understood as: the two longitudinally adjacent photovoltaic modules 1 are in contact.

[0076] In the embodiment of the present application, the longitudinal direction is parallel to the maximum surface area of the photovoltaic module 1. An angle is formed between the longitudinal and transverse directions, which can be a right angle or an acute angle. To facilitate the installation of the photovoltaic module 1, the angle between the longitudinal and transverse directions can be a right angle, i.e., the longitudinal direction is perpendicular to the transverse direction.

[0077] Combine Figure 3 、 Figure 10 、 Figure 13 and Figure 20 As shown, in two photovoltaic modules 1 adjacent in the longitudinal direction, water on the higher one flows from the longitudinal first end 13 of the higher one to the longitudinal second end 14 of the higher one, and then flows from the longitudinal second end 14 of the higher one to the longitudinal first end 13 of the lower one, and then flows from the longitudinal first end 13 of the lower one to the longitudinal second end 14 of the lower one, and so on. The water on the photovoltaic module 1 finally flows to the longitudinal second end 14 of the photovoltaic module 1 at the lowest position and then flows to the set position (such as the second drainage channel 4 mentioned below). Therefore, all photovoltaic modules 1 distributed in sequence in the longitudinal direction form a diversion structure, and there is no need to set up a separate longitudinal water trough.

[0078] From the above content, it can be seen that in the waterproof structure of the photovoltaic system provided in the embodiment of the present application, all photovoltaic components 1 distributed in sequence in the longitudinal direction form a diversion structure, and all photovoltaic components 1 distributed in sequence in the transverse direction form a diversion structure. There is no need to set up longitudinal water troughs and transverse water troughs separately. Compared with the existing technology, the components of the photovoltaic bracket 2 are reduced, the node connection in the photovoltaic bracket 2 is simpler, the structure of the photovoltaic bracket 2 is simplified, and the installation of the photovoltaic bracket 2 is simplified, thereby improving the construction efficiency of the photovoltaic system.

[0079] At the same time, in the photovoltaic system waterproof structure provided by the embodiment of the present application, since there is no need to set up separate horizontal water grooves and load-bearing grooves, the force system of the photovoltaic bracket 2 is simpler, which ensures the strength and other mechanical properties of the photovoltaic bracket 2, improves the structural safety performance of the entire photovoltaic bracket 2, and also improves the waterproof reliability of the photovoltaic system waterproof structure, and also improves the user experience; since there is no need to set up separate longitudinal water grooves and horizontal water grooves, the material usage of the photovoltaic bracket 2 is simplified, the cost of the photovoltaic bracket 2 is reduced, and thus the cost of the photovoltaic system is reduced; it also simplifies the structure of the photovoltaic bracket 2, and improves the neatness of the photovoltaic bracket 2, thereby improving the aesthetics of the photovoltaic system and improving the user experience.

[0080] like Figure 3 、 Figure 4 and Figure 13 As shown, in some embodiments, the photovoltaic system waterproof structure may further include a first drainage channel 3 and a second drainage channel 4 .

[0081] In the longitudinal direction, the first drainage channel 3 is distributed on the same side of all photovoltaic components 1, and the first drainage channel 3 is close to the lowest longitudinal second end 14; in the transverse direction, the second drainage channel 4 is distributed on the same side of all photovoltaic components 1, and the second drainage channel 4 is close to the lowest transverse second end 12.

[0082] The first drainage channel 3 is used to collect water flowing longitudinally along the photovoltaic modules 1. This means that all water flowing longitudinally along the photovoltaic modules 1 ultimately flows into the first drainage channel 3. The water in the first drainage channel 3 is then drained to the ground or other locations, further improving the waterproof performance. The second drainage channel 4 is used to collect water flowing transversely along the photovoltaic modules 1. This means that all water flowing transversely along the photovoltaic modules 1 ultimately flows into the second drainage channel 4. The water in the second drainage channel 4 is then drained to the ground or other locations, further improving the waterproof performance of the photovoltaic system. This can reduce the number of second drainage channels 4, thereby simplifying the structure of the photovoltaic system.

[0083] The first drainage channel 3 and the second drainage channel 4 may be connected or not connected. The first drainage channel 3 and the second drainage channel 4 may both be drainage gutters or other structures, which is not limited in the present embodiment.

[0084] In order to facilitate the drainage of water in the first drainage channel 3 and the second drainage channel 4, the photovoltaic system waterproof structure also includes a drainage device; wherein the drainage device is connected to the lower end of the first drainage channel 3, and the drainage device is used to drain the water in the first drainage channel 3 to the ground; the drainage device is also connected to the lower end of the second drainage channel 4, and the drainage device is used to drain the water in the second drainage channel 4 to the ground.

[0085] The specific structure of the drainage device is selected according to actual conditions. For example, the drainage device includes a drainage pump and a drainage pipe connected to the drainage pump, etc. The embodiment of the present application does not limit this.

[0086] In some other embodiments, the waterproof structure of the photovoltaic system may not include the first drainage channel 3. In this case, water flowing in the longitudinal direction can be directly discharged to the ground through the photovoltaic module 1. Correspondingly, the waterproof structure of the photovoltaic system may not include the second drainage channel 4. In this case, water flowing in the transverse direction can be directly discharged to the ground through the photovoltaic module 1.

[0087] In the photovoltaic system waterproof structure provided in the embodiment of the present application, in order to facilitate the realization of: all photovoltaic components 1 distributed in sequence in the longitudinal direction forming a diversion structure, and all photovoltaic components 1 distributed in sequence in the transverse direction forming a diversion structure, this can be achieved by designing a photovoltaic bracket 2.

[0088] In some embodiments, as Figure 4 As shown, the photovoltaic support 2 includes: a support column 21, a longitudinal beam 22 and a transverse beam 23.

[0089] It should be noted that the longitudinal beam 22 can also be understood as a main beam, and the transverse beam 23 can also be understood as a purlin.

[0090] There are a plurality of support pillars 21 , and the support pillars 21 are distributed in an array, for example, the support pillars 21 are distributed along rows and columns.

[0091] The length direction of the longitudinal beam 22 is parallel to the longitudinal direction, and the first end of the longitudinal beam 22 is higher than the second end of the longitudinal beam 22; the length direction of the cross beam 23 is parallel to the transverse direction, and the first end of the cross beam 23 is higher than the second end of the cross beam 23, and the cross beam 23 and the longitudinal beam 22 are fixedly connected.

[0092] One of the longitudinal beam 22 and the transverse beam 23 is fixed to the support column 21. In order to facilitate installation and improve the stability of the photovoltaic bracket 2, the longitudinal beam 22 can be fixed to the support column 21, and the transverse beam 23 can be indirectly fixedly connected to the support column 21 through the longitudinal beam 22 and the support column 21, and the photovoltaic module 1 is fixed to the transverse beam 23.

[0093] In actual situations, the cross beam 23 may be fixed to the support column 21 , the longitudinal beam 22 may be indirectly fixedly connected to the support column 21 via the cross beam 23 , and the photovoltaic module 1 may be fixed to the longitudinal beam 22 .

[0094] The fixed connection structure between the cross beam 23 and the support column 21, the fixed connection structure between the longitudinal beam 22 and the support column 21, and the fixed connection structure between the cross beam 23 and the longitudinal beam 22 are selected according to actual conditions and are not limited in this embodiment of the present application.

[0095] It should be noted that when the photovoltaic bracket 2 includes a longitudinal beam 22 and a transverse beam 23, the first drainage channel 3 and the transverse beam 23 are distributed side by side, and the first drainage channel 3 is distributed at the second end of the longitudinal beam 22; the second drainage channel 4 and the longitudinal beam 22 are distributed side by side, and the second drainage channel 4 is distributed at the second end of the transverse beam 23.

[0096] In the embodiment of the present application, since a transverse water gutter is not required, the crossbeam 23 can be a pipe, and the cross section of the crossbeam 23 is a closed ring. This effectively improves the mechanical properties of the crossbeam 23, such as stiffness and strength, and enhances the structural safety of the photovoltaic bracket 2. It also prevents deformation of the crossbeam 23 due to weak cross-sectional stiffness, thereby preventing water leakage caused by deformation of the crossbeam 23, improving the waterproof reliability of the photovoltaic system waterproof structure, and enhancing the user experience.

[0097] The two ends of the above-mentioned pipe fitting can be closed or have openings. In actual conditions, the crossbeam 23 can also be a cable. In the case where the load-bearing is not considered, the crossbeam 23 can also be a solid structure, such as a solid rod.

[0098] In the embodiment of the present application, since a longitudinal water gutter is not required, the longitudinal beam 22 can be a pipe, and the cross-section of the longitudinal beam 22 is a closed ring. This effectively improves the mechanical properties of the longitudinal beam 22, such as stiffness and strength, and enhances the structural safety of the photovoltaic bracket 2. It also prevents deformation of the longitudinal beam 22 due to weak cross-sectional stiffness, thereby preventing water leakage caused by deformation of the longitudinal beam 22, improving the waterproof reliability of the photovoltaic system waterproof structure, and enhancing the user experience.

[0099] The two ends of the above-mentioned pipe fitting can be closed or have openings. In actual conditions, the longitudinal beam 22 can also be a cable. In the case where the load-bearing structure is not considered, the longitudinal beam 22 can also be a solid structure, such as a solid rod.

[0100] In the photovoltaic bracket 2 , the specific number of the cross beams 23 and the longitudinal beams 22 is selected according to actual conditions, and the embodiment of the present application does not limit this.

[0101] In other embodiments, the photovoltaic bracket 2 may also have other structures and is not limited to the above embodiments.

[0102] In the embodiment of the present application, in order to facilitate the installation of the photovoltaic component 1, the photovoltaic bracket 2 further includes a component support seat 24.

[0103] When the longitudinal beam 22 is fixed to the support column 21 and the cross beam 23 is fixed to the longitudinal beam 22, the module support base 24 is fixed to the cross beam 23, and the photovoltaic module 1 is fixed to the module support base 24, so that the photovoltaic module 1 is fixedly connected to the cross beam 23 through the module support base 24. In order to facilitate installation, disassembly and maintenance, the module support base 24 is detachably fixed to the cross beam 23. For example, Figure 7 As shown, the component support base 24 is detachably fixed to the crossbeam 23 by a first fastener 27 . The first fastener 27 can be a self-tapping screw or other fasteners.

[0104] When the crossbeam 23 is fixed to the support column 21 and the longitudinal beam 22 is fixed to the crossbeam 23, the module support base 24 is fixed to the longitudinal beam 22, and the photovoltaic module 1 is fixed to the module support base 24, thereby achieving a fixed connection between the photovoltaic module 1 and the longitudinal beam 22 via the module support base 24. To facilitate installation, disassembly, and maintenance, the module support base 24 is detachably fixed to the longitudinal beam 22.

[0105] The specific structure of the component support seat 24 is selected according to actual conditions. In some embodiments, the component support seat 24 includes a connected component mounting portion 243 and a beam mounting portion 241, the component mounting portion 243 is used to install the photovoltaic component 1, and the beam mounting portion 241 is used to be fixedly connected to the crossbeam 23 or the longitudinal beam 22. In order to improve stability, there are two beam mounting portions 241, and the two beam mounting portions 241 are respectively located at both ends of the component mounting portion 243. In order to facilitate the installation of the component support seat 24 and the beam (crossbeam 23 or longitudinal beam 22), the spacing between the two beam mounting portions 241 can be adjusted. Exemplarily, the component mounting portion 243 and the beam mounting portion 241 are connected by a deformation portion 242, and the length of the deformation portion 242 can be adjusted in the distribution direction of the two beam mounting portions 241.

[0106] It should be noted that when the beam mounting portion 241 is fixed to the cross beam 23 , the distribution direction of the two beam mounting portions 241 is the horizontal direction; when the beam mounting portion 241 is fixed to the longitudinal beam 22 , the distribution direction of the two beam mounting portions 241 is the longitudinal direction.

[0107] The above-mentioned deformation portion 242 can be a bent plate, for example, the bent plate includes a curved bent plate and / or a straight bent plate, which is not limited in the embodiment of the present application.

[0108] In actual situations, the component support seat 24 can also be other structures, which is not limited in the embodiments of the present application.

[0109] In the embodiment of the present application, the specific laying method of the photovoltaic assembly 1 is selected according to the actual situation.

[0110] In some embodiments, there is a first gap between two adjacent photovoltaic modules 1 in the transverse direction; two adjacent photovoltaic modules 1 in the longitudinal direction are in contact; or, two adjacent photovoltaic modules 1 in the transverse direction are in contact and there is a first gap between two adjacent photovoltaic modules 1 in the longitudinal direction.

[0111] In some other embodiments, there is a first gap between two adjacent photovoltaic components 1 in the transverse direction and a second gap between two adjacent photovoltaic components 1 in the longitudinal direction; or, there is a first gap between two adjacent photovoltaic components in the longitudinal direction and a second gap between two adjacent photovoltaic components in the transverse direction.

[0112] It should be noted that the first gap and the second gap can be equal or unequal. The specific sizes of the first gap and the second gap are selected according to actual conditions.

[0113] The following two embodiments illustrate the relative relationship between two adjacent photovoltaic modules 1 in the transverse direction and the relative relationship between two adjacent photovoltaic modules 1 in the longitudinal direction.

[0114] Example 1

[0115] like Figure 3-Figure 12 As shown, the photovoltaic system waterproof structure provided in the first embodiment of the present application includes a photovoltaic bracket 2 and a photovoltaic assembly 1.

[0116] For the description of the photovoltaic bracket 2 and the photovoltaic assembly 1, please refer to the previous text and will not be repeated here.

[0117] In the first embodiment of the present application, Figure 11 As shown, in the transverse direction, there is a first gap between two adjacent photovoltaic modules 1 ; in the longitudinal direction, there is a second gap between two adjacent photovoltaic modules 1 .

[0118] In the first embodiment of the present application, there are at least four photovoltaic modules 1. Specifically, two photovoltaic modules 1 adjacent in the horizontal direction are a first photovoltaic module 1a and a second photovoltaic module 1b, with the second photovoltaic module 1b being taller than the first photovoltaic module 1a. Two other photovoltaic modules 1 adjacent in the horizontal direction are a third photovoltaic module 1c and a fourth photovoltaic module 1d, with the fourth photovoltaic module 1d being taller than the third photovoltaic module 1c. The first photovoltaic module 1a and the third photovoltaic module 1c are adjacent in the vertical direction, with the third photovoltaic module 1c being taller than the first photovoltaic module 1a. The second photovoltaic module 1b and the fourth photovoltaic module 1d are adjacent in the vertical direction, with the fourth photovoltaic module 1d being taller than the second photovoltaic module 1b.

[0119] As described above, there is a first gap between two adjacent photovoltaic modules 1 in the horizontal direction, and a second gap between two adjacent photovoltaic modules 1 in the vertical direction. Therefore, there is a first gap between the first photovoltaic module 1a and the second photovoltaic module 1b, a first gap between the third photovoltaic module 1c and the fourth photovoltaic module 1d, a second gap between the first photovoltaic module 1a and the third photovoltaic module 1c, and a second gap between the second photovoltaic module 1b and the fourth photovoltaic module 1d. To meet this requirement, the third photovoltaic module 1c can be partially overlapped between the fourth photovoltaic module 1d and the second photovoltaic module 1b, with the third gap between the third photovoltaic module 1c and the second photovoltaic module 1b, or the third photovoltaic module 1c and the second photovoltaic module 1b can be in contact. To improve waterproofing, the third photovoltaic module 1c and the second photovoltaic module 1b can be in contact. This also improves the stability of the photovoltaic module 1.

[0120] In the first embodiment of the present application, in order to improve the waterproof performance of the photovoltaic system, the second gap is larger than the first gap, and the second gap is larger than the third gap. The first gap and the third gap can be equal or unequal.

[0121] In actual situations, the second gap may be no larger than the first gap, and the second gap may be no larger than the third gap, and the present invention is not limited to the above situation.

[0122] In the first embodiment of the present application, two photovoltaic modules 1 with a first gap (two photovoltaic modules 1 adjacent in the transverse direction) are connected by a connector 25 and are both fixed to the module support base 24 by the connector 25. This facilitates ensuring that the first gap is formed between the two adjacent photovoltaic modules 1 and facilitates controlling the size of the first gap, thereby facilitating the installation of the photovoltaic modules 1. Moreover, the connector 25 connects the two photovoltaic modules 1 with the first gap and also connects the photovoltaic modules 1 and the module support base 24. This reduces the number of components required to fix the photovoltaic modules 1, thereby simplifying the installation of the photovoltaic modules 1 and the structure of the photovoltaic bracket 2, thereby improving the installation efficiency of the photovoltaic system waterproof structure.

[0123] For the structure of the component support base 24, please refer to the above text and will not be repeated here.

[0124] The connecting member 25 may be a pressing block or other structures. The specific structure of the connecting member 25 may be selected according to actual conditions.

[0125] like Figure 7-Figure 9As shown, the connector 25 includes a pressing block, which includes a slot portion 251 and a mounting portion 253. The slot portion 251 is higher than the mounting portion 253 and connected to the slot portion 251. The mounting portion 253 is fixedly connected to the module support base 24. Among the two photovoltaic modules 1 with a first gap (two photovoltaic modules 1 adjacent in the horizontal direction), the higher one is inserted into the slot portion 251, and the lower one is pressed against the module support base 24 through the slot portion 251.

[0126] The slot portion 251 has two slot side panels 2512, one of which is close to the mounting portion 253 and the other is further away from the mounting portion 253. The width of the first gap is the thickness of the slot side panel 2512 in the slot portion 251 close to the mounting portion 253. Thus, by controlling the thickness of the slot side panel 2512 in the slot portion 251 close to the mounting portion 253, the size of the first gap can be controlled.

[0127] In order to ensure the connection stability, the slot portion 251 and the mounting portion 253 can be fixedly connected. The slot portion 251 and the mounting portion 253 can be an integrated structure or a split structure, which is not limited in the embodiment of the present application.

[0128] The slot portion 251 includes a slot 2511 for inserting a photovoltaic module 1. To facilitate installation of the lower-positioned photovoltaic module 1 between two laterally adjacent photovoltaic modules 1, a notch 252 is provided on the bottom side of the slot portion 251. The notch 252 and the module support base 24 form a module mounting structure 28 that positions and secures the lower-positioned photovoltaic module 1. This facilitates proper installation of the photovoltaic module 1, simplifies installation, and improves installation efficiency.

[0129] Exemplarily, the notch 252 includes a notch side wall 2521 and a notch upper wall 2522, and the notch side wall 2521 and the notch upper wall 2522 are vertically connected. The notch side wall 2521, the notch upper wall 2522 and the component support seat 24 form the above-mentioned component mounting structure 28. Among them, the notch side wall 2521 is used to abut against the side of the photovoltaic component 1 to achieve the limitation of the photovoltaic component 1; the notch upper wall 2522 and the component support seat 24 cooperate to limit the photovoltaic component 1 in the thickness direction of the photovoltaic component 1. Since the connector 25 and the component support seat 24 are fixedly connected, the component mounting structure 28 formed by the connector 25 and the component support seat 24 can limit and fix the above-mentioned lower-positioned photovoltaic component 1.

[0130] It should be noted that part of the slot 2511 and part of the component mounting structure 28 overlap in the depth direction of the slot 2511, which can also be understood as: part of the slot 2511 and part of the notch 252 overlap in the depth direction of the slot 2511, so as to ensure that: in the two adjacent photovoltaic components 1 in the transverse direction, the transverse second end 12 of one is stacked on top of the transverse first end 11 of the other.

[0131] To facilitate installation and removal, the mounting portion 253 is removably fixedly connected to the component support base 24. Exemplarily, the mounting portion 253 and the component support base 24 are removably fixedly connected via a third fastener or a snap-fit structure, wherein the third fastener 26 may include a bolt and a nut. Of course, the mounting portion 253 may also be fixed to the component support base 24 by welding or other means.

[0132] To improve the connection stability between the mounting portion 253 and the component support base 24, the mounting portion 253 may include a first mounting plate 2531, a second mounting plate 2532, and a connecting plate 2533 connecting the first mounting plate 2531 and the second mounting plate 2532. The second mounting plate 2532 is further away from the component support base 24 than the first mounting plate 2531. The second mounting plate 2532 and the first mounting plate 2531 are fixed to the component support base 24 via the same fastener. It should be noted that the same fastener can be understood as the third fastener 26 mentioned above.

[0133] In actual situations, the mounting portion 253 may also be other structures, which is not limited in the first embodiment of the present application.

[0134] The specific shapes of the slot portion 251 and the mounting portion 253 are selected according to actual conditions. For example, the slot portion 251 and the mounting portion 253 are both U-shaped, and the openings of the slot portion 251 and the mounting portion 253 face opposite directions.

[0135] In the first embodiment of the present application, the method for installing a photovoltaic module 1 includes: first installing a support column 21, a longitudinal beam 22, and a transverse beam 23; securing a module support base 24 to the transverse beam 23; placing the photovoltaic module 1 on the left side (the lower of the two adjacent photovoltaic modules 1 in a horizontal direction); placing a connector 25 on the module support base 24, such that the connector 25 presses against the first transverse end 11 of the left photovoltaic module 1; then securing the connector 25 to the module support base 24 so that the connector 25 presses against the left photovoltaic module 1 and prevents the left photovoltaic module 1 from moving; and finally, installing the photovoltaic module 1 on the right side (the higher of the two adjacent photovoltaic modules 1 in a horizontal direction) in the slot 251 of the connector 25. The installation of the remaining photovoltaic modules 1 is completed by analogy.

[0136] It can be seen from the above-mentioned installation method that the connection convenience and connection reliability of the photovoltaic module 1 are improved by cleverly designing the structure of the pressing block.

[0137] The above-mentioned pressing block is similar to a "bow shape". Of course, the pressing block can also be selected to be other shapes, and the embodiments of the present application do not limit this.

[0138] In the embodiment of the present application, the photovoltaic components 1 can also be arranged in other ways. Figure 12 As shown, in the longitudinal direction, there is a first gap between two adjacent photovoltaic modules 1; in the transverse direction, there is a second gap between two adjacent photovoltaic modules 1. In this case, there is a first gap between the first photovoltaic module 1a and the third photovoltaic module 1c, a first gap between the second photovoltaic module 1b and the fourth photovoltaic module 1d, a second gap between the first photovoltaic module 1a and the second photovoltaic module 1b, and a second gap between the third photovoltaic module 1c and the fourth photovoltaic module 1d. To meet this requirement, the second photovoltaic module 1b can be partially overlapped between the third photovoltaic module 1c and the fourth photovoltaic module 1d, with the third photovoltaic module 1c and the second photovoltaic module 1b having a third gap, or the second photovoltaic module 1b and the third photovoltaic module 1c can be in contact. To improve waterproofing, the third photovoltaic module 1c and the second photovoltaic module 1b can be in contact. This also improves the stability of the photovoltaic module 1.

[0139] For the relative sizes of the first gap, the second gap and the third gap, please refer to the previous text and will not be repeated here.

[0140] In the above structure, the two photovoltaic modules 1 with the first gap (two adjacent photovoltaic modules 1 in the longitudinal direction) are also connected by a connector 25 and are both fixed to the module support base 24 by the connector 25. The technical effects brought about by this connection structure can be referred to above and will not be repeated here. Correspondingly, the connector 25 can also be referred to above and will not be repeated here.

[0141] In the first embodiment of the present application, there is a first gap between two photovoltaic modules 1 adjacent in the transverse direction, and a second gap between two photovoltaic modules 1 adjacent in the longitudinal direction; or, there is a first gap between two photovoltaic modules 1 adjacent in the longitudinal direction, and a second gap between two photovoltaic modules 1 adjacent in the transverse direction. The first gap is smaller and the second gap is larger. In the case of strong winds, water flowing along the photovoltaic modules 1 is more likely to be blown into the second gap, causing the water to reach the back of the photovoltaic modules 1 through the second gap, affecting the waterproof performance of the photovoltaic system. In order to reduce the second gap between two photovoltaic modules 1 adjacent in the longitudinal direction, the thickness of the photovoltaic modules 1 can be reduced. In order to reduce the impact of the second gap on the waterproof performance, the overlapping area of the projections of the two photovoltaic modules 1 adjacent in the longitudinal direction can be increased, and a windshield component can also be provided at the above-mentioned second gap.

[0142] It should be noted that the projection of the photovoltaic module 1 refers to the projection of the photovoltaic module 1 along its thickness direction.

[0143] Example 2

[0144] like Figure 13-Figure 21 As shown, the photovoltaic system waterproof structure provided in the second embodiment of the present application includes a photovoltaic bracket 2 and a photovoltaic component 1.

[0145] For the description of the photovoltaic bracket 2 and the photovoltaic assembly 1, please refer to the previous text and will not be repeated here.

[0146] In some embodiments, as Figure 21 As shown, in the transverse direction, there is a first gap between two adjacent photovoltaic modules 1 ; in the longitudinal direction, the two adjacent photovoltaic modules 1 are in contact.

[0147] In the second embodiment of the present application, there are at least four photovoltaic modules 1. Specifically, two photovoltaic modules 1 adjacent in the horizontal direction are a first photovoltaic module 1a and a second photovoltaic module 1b, with the second photovoltaic module 1b being higher than the first photovoltaic module 1a; two other adjacent photovoltaic modules 1 in the horizontal direction are a third photovoltaic module 1c and a fourth photovoltaic module 1d, with the fourth photovoltaic module 1d being higher than the third photovoltaic module 1c; wherein the first photovoltaic module 1a and the third photovoltaic module 1c are arranged in sequence and adjacent in the vertical direction, with the third photovoltaic module 1c being higher than the first photovoltaic module 1a; the second photovoltaic module 1b and the fourth photovoltaic module 1d are arranged in sequence and adjacent in the vertical direction, with the fourth photovoltaic module 1d being higher than the second photovoltaic module 1b.

[0148] As previously mentioned, a first gap exists between two adjacent photovoltaic modules 1 in the horizontal direction. In the vertical direction, adjacent photovoltaic modules 1 are in contact. For example, a first gap exists between the first photovoltaic module 1a and the second photovoltaic module 1b, and a first gap exists between the third photovoltaic module 1c and the fourth photovoltaic module 1d. The first photovoltaic module 1a and the third photovoltaic module 1c are in contact, and the second photovoltaic module 1b and the fourth photovoltaic module 1d are in contact. To achieve this structure, a portion of the second photovoltaic module 1b is stacked between the third photovoltaic module 1c and the fourth photovoltaic module 1d, with the third photovoltaic module 1c and the second photovoltaic module 1b in contact. This reduces the gaps between the photovoltaic modules 1, improves waterproof performance, and also enhances the stability of the photovoltaic modules 1.

[0149] In some embodiments, two laterally adjacent photovoltaic modules 1 (two photovoltaic modules 1 with a first gap) are connected by a connector 25, and both laterally adjacent photovoltaic modules 1 are fixed to the module support base 24 of the photovoltaic bracket 2 by the connector 25. For the structure of the module support base 24 and the connector 25, please refer to the previous text and will not be repeated here.

[0150] To reduce the impact of the first gap on waterproof performance, the photovoltaic system waterproof structure also includes a windshield 5, which is mounted on the connector 25 and blocks at least part of the first gap. This ensures reliable waterproofing even in strong winds.

[0151] It should be noted that, for example, the windshield 5 blocks the entire first gap, or blocks part of the first gap. In the case where the windshield 5 blocks part of the first gap, a smaller gap exists between the windshield 5 and the two photovoltaic modules 1 having the first gap.

[0152] The windshield member 5 may be a windshield sheet or other types, and this is not limited in the second embodiment of the present application.

[0153] To improve the windshield 5's windshield effect, the windshield 5 can be fixedly connected to the connector 25. For example, the windshield 5 is fixed to the connector 25 by welding or bonding. In this case, the connector 25 provided in the first embodiment can be adaptively adjusted to ensure the installation of the windshield 5.

[0154] like Figure 16-Figure 19 As shown, the windshield 5 is disposed in the slot portion 251 of the connector 25. It should be noted that the lower one of the two photovoltaic modules 1 with the first gap is located on the same side of the pressing block as the windshield 5.

[0155] In order to simplify installation, the slot portion 251 is provided with a slot 2511 and a mounting slot 2513; the higher one of the two photovoltaic modules 1 with the first gap is inserted into the slot 2511, the mounting slot 2513 is lower than the slot 2511, and the windshield 5 is arranged in the mounting slot 2513. In this case, Figure 17 As shown, there is a small gap between the wind shield 5 and the upper left photovoltaic assembly 1 , and there is a small gap between the wind shield 5 and the lower right photovoltaic assembly 1 .

[0156] The mounting groove 2513 may be a through-groove structure, which facilitates placement of the windshield member 5. Of course, the mounting groove 2513 may not be a through-groove structure, and this is not limited in the second embodiment of the present application.

[0157] The depth of the installation groove 2513 is selected according to actual conditions and is not limited in this embodiment of the present application.

[0158] The width of the mounting groove 2513 is related to the size of the first gap. For example, if the thickness of the side plate of the mounting groove 2513 remains unchanged, the larger the width of the mounting groove 2513, the larger the first gap; and the smaller the width of the mounting groove 2513, the smaller the first gap.

[0159] It should be noted that the width direction of the mounting groove 2513 is the width direction of the slot 2511 , and is also the thickness direction of the photovoltaic module 1 .

[0160] In the second embodiment of the present application, the installation method of the photovoltaic assembly 1 includes: first installing the support column 21, the longitudinal beam 22 and the cross beam 23; fixing the assembly support seat 24 on the cross beam 23; placing the photovoltaic assembly 1 on the left (the lower one of the two adjacent photovoltaic assemblies 1 in the horizontal direction); placing the connector 25 on the assembly support seat 24, and making the connector 25 press the first horizontal end 11 of the photovoltaic assembly 1 on the left, and then fixing the connector 25 on the assembly support seat 24 so that the connector 25 presses the photovoltaic assembly 1 on the left and the photovoltaic assembly 1 on the left does not move; fixing the wind shield 5 to the slot portion 251 of the connector 25; finally, installing the photovoltaic assembly 1 on the right ((the higher one of the two adjacent photovoltaic assemblies 1 in the horizontal direction) in the slot portion 251 of the connector 25. In sequence, complete the installation of the remaining photovoltaic assemblies 1.

[0161] It can be seen from the above-mentioned installation method that the connection convenience and connection reliability of the photovoltaic module 1 are improved by cleverly designing the structure of the pressing block.

[0162] The above-mentioned pressing block is similar to a "bow shape". Of course, the pressing block can also be selected to be other shapes, and the embodiments of the present application do not limit this.

[0163] In the embodiment of the present application, the photovoltaic components 1 can also be arranged in other ways. Figure 22As shown, in some other embodiments, adjacent photovoltaic modules 1 are in contact in the horizontal direction, and a first gap is provided between adjacent photovoltaic modules 1 in the vertical direction. In this case, the first photovoltaic module 1a and the second photovoltaic module 1b are in contact, and the third photovoltaic module 1c and the fourth photovoltaic module 1d are in contact. There is a first gap between the first photovoltaic module 1a and the third photovoltaic module 1c, and there is a first gap between the second photovoltaic module 1b and the fourth photovoltaic module 1d. To meet this structural requirement, the third photovoltaic module 1c can be partially overlapped between the second photovoltaic module 1b and the fourth photovoltaic module 1d, with the second photovoltaic module 1b and the third photovoltaic module 1c in contact. This can also reduce the gap between the photovoltaic modules 1, improve waterproof performance, and enhance the stability of the photovoltaic modules 1.

[0164] In the above embodiment, the two photovoltaic modules 1 with the first gap (two adjacent photovoltaic modules 1 in the longitudinal direction) are also connected by a connector 25 and are both fixed to the module support base 24 by the connector 25. The technical effects brought about by this connection structure can be referred to above and will not be repeated here. Correspondingly, the connector 25 can also be referred to above and will not be repeated here.

[0165] In the above embodiment, the wind shield 5 mentioned above may also be provided. In this case, the structure of the connecting member 25 may also refer to the above description and will not be repeated here.

[0166] In the second embodiment of the present application, a first gap is provided between two adjacent photovoltaic modules 1 in the transverse direction, and the adjacent photovoltaic modules 1 are in contact in the longitudinal direction; alternatively, two adjacent photovoltaic modules 1 are in contact in the transverse direction, and a first gap is provided between two adjacent photovoltaic modules 1 in the longitudinal direction. The windshield 5 blocks at least a portion of the first gap, thereby reducing the probability of water passing through the gaps between the photovoltaic modules 1 and reaching the back of the photovoltaic modules 1. This also reduces the amount of water that passes through the gaps between the photovoltaic modules 1 and reaches the back of the photovoltaic modules 1, effectively improving the waterproof performance and waterproof reliability under strong winds.

[0167] Based on the photovoltaic system waterproof structure provided in the above embodiment, an embodiment of the present application further provides a photovoltaic system, which includes the photovoltaic system waterproof structure described in the above embodiment.

[0168] Since the photovoltaic system waterproof structure provided in the above embodiments has the above technical effects, the photovoltaic system provided in the embodiments of the present application includes the photovoltaic system waterproof structure described in the above embodiments. Therefore, the photovoltaic system provided in the embodiments of the present application also has corresponding technical effects, which will not be repeated here.

[0169] The photovoltaic system may be a rooftop photovoltaic system, a ground-mounted photovoltaic system, a building-integrated photovoltaic system, or a floating photovoltaic system. For example, the rooftop photovoltaic system may be a BAPV (Building Attached Photovoltaic) or a BIPV (Building Integrated Photovoltaic), which is not limited in the present embodiment.

[0170] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
