Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic, and particularly relates to a photovoltaic power station installed on a roof.

Background Art

[0002] At present, there are many types of housing structures in the household photovoltaic market. Among them, the inclined roof type accounts for a relatively large proportion, which can be divided into single-slope inclined roofs, north-south slope inclined roofs, four-sided inclined roofs, etc. Among them, single-slope inclined roofs and north-south slope inclined roofs are more common, and there are also mature photovoltaic installation structures. The four-sided inclined roof structure form is also increasing, but this type of structure is often in the form of foreign-style buildings, with a small floor area. At present, most of the market only uses two forms, namely hanging hooks and overhead, to lay the north-south slopes. Affected by the azimuth angle, the east-west slopes cannot be reasonably utilized, resulting in a small installed capacity, thus unable to meet the market and customer needs.

[0003] If the east-west slope strings of the four-sided inclined roof are mixed-connected with the north-south slopes, the result will greatly reduce the power generation efficiency, be unsafe and less economical; therefore, how to reasonably utilize the east-west slopes, how to better increase the installed capacity of a single household, and ensure the structural safety while being more economical and reasonable are the main problems faced.

Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a photovoltaic module installation structure for full coverage of a four-sided inclined roof, which realizes the simultaneous laying of photovoltaic modules on four slopes, improves the power generation efficiency, and ensures the structural safety.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A photovoltaic module installation structure for full coverage of a four-sided inclined roof, the roof includes two first inclined roofs symmetrically arranged on both longitudinal sides and two second inclined roofs symmetrically arranged on both transverse sides. The photovoltaic module installation structure includes two diagonal brackets symmetrically arranged on both longitudinal sides, and the two diagonal brackets integrally cover the space above the two first inclined roofs and the two second inclined roofs. The diagonal brackets are fixed on the first inclined roofs, and a lateral bracket is arranged between the diagonal brackets and the second inclined roofs.

[0007] Preferably, the diagonal bracket includes a plurality of lower inclined beams arranged side by side in the transverse direction and a plurality of upper inclined beams arranged side by side in the transverse direction. The upper inclined beams are correspondingly arranged above the lower inclined beams, and a plurality of support columns are arranged between the lower inclined beams and the upper inclined beams. The lower inclined beams are fixed to the first inclined roofs.

[0008] Preferably, the height of the support columns increases or decreases one by one from the lower side to the upper side to adjust the inclination angle of the upper inclined beams.

[0009] Preferably, the longitudinal lower end of the upper inclined beam is longer than that of the lower inclined beam, and a lower end support assembly is provided between the longitudinal lower end of the inclined support and the house.

[0010] Preferably, longitudinal platforms are provided on both longitudinal sides of the roof. The lower end support assembly includes a lower end vertical column and a lower end inclined strut. The lower end of the lower end vertical column is fixed to the longitudinal platform. The lower end vertical column is connected to the end of the lower inclined beam and the upper end is connected to the upper inclined beam. One end of the lower end inclined strut is connected to the lower end vertical column and the other end is connected to the upper inclined beam.

[0011] Preferably, the lateral support includes a side inclined beam extending along the inclination direction of the second inclined roof surface, a side vertical column perpendicular to the side inclined beam, and a side inclined strut connecting the side inclined beam and the side vertical column. The side inclined beam is fixed to the second inclined roof surface.

[0012] Preferably, support hook assemblies are installed on both the first inclined roof surface and the second inclined roof surface. The support hook assembly on the first inclined roof surface is connected to the inclined support, and the support hook assembly on the second inclined roof surface is connected to the lateral support.

[0013] Preferably, transverse platforms are provided on both transverse sides of the roof. An edge span support assembly is provided between the inclined support and the transverse platform.

[0014] Preferably, the edge span support assembly includes a first edge span support and a second edge span support. The first edge span support is arranged at the longitudinal middle position, and two second edge span supports are symmetrically arranged on both longitudinal sides of the first edge span support.

[0015] Preferably, the first edge span support includes two first edge span vertical columns arranged side by side longitudinally and a strengthening rod connecting the two first edge span vertical columns. The lower ends of the two first edge span vertical columns are fixed to the transverse platform, and the upper ends are respectively connected to the two inclined supports. The second edge span support includes a second edge span vertical column and two edge span inclined struts arranged on both longitudinal sides of the first edge span vertical column. The lower end of the second edge span vertical column is fixed to the transverse platform, and one end of the edge span inclined strut is connected to the second edge span vertical column and the other end is connected to the inclined support.

[0016] The utility model adopts the above technical solutions and has the following beneficial effects:

[0017] 1. Aiming at the problem that the four-sided inclined roof cannot be fully paved (the east and west slopes cannot be reasonably utilized), the utility model provides a relatively reasonable structural form. In the above technical solutions, two inclined supports are correspondingly arranged on both longitudinal sides, and the two inclined supports integrally cover the spaces above the two first inclined roof surfaces (the south slope inclined roof surface and the north slope inclined roof surface) and the two second inclined roof surfaces (the east slope inclined roof surface and the west slope inclined roof surface), so as to utilize the spaces above the four inclined roof surfaces, realize the simultaneous laying of photovoltaic modules on the four slopes, and increase the power generation area.

[0018] Moreover, the two diagonal brackets are equivalent to forming two complete installation ramps, converting the areas where laying is impossible on the east and west slopes into a north-south double-slope form, which is combined with the installation ramps above the original south-slope inclined roof to form a whole. The conversion structural form of the east and west slopes is more reasonable, and the power generation efficiency is improved compared with the connection of the east and west slope strings and the north-south slope mixed connection.

[0019] Since the photovoltaic modules cover the entire roof, blocking direct sunlight on the roof and forming a photovoltaic heat insulation layer, it not only effectively protects the roof surface but also can reduce the indoor temperature by 3°C - 5°C, effectively alleviating the stuffiness of the house on hot summer days.

[0020] Secondly, the two diagonal brackets are installed independently. If the ridge is low or there is no ridge, they can extend above the ridge. If the ridge is high, a space can also be formed between the two diagonal brackets to avoid the high ridge, so it can adapt to more house types.

[0021] Finally, the diagonal brackets are fixed on the first inclined roof, and a lateral bracket is provided between the diagonal brackets and the second inclined roof. Thus, the diagonal brackets are fixed above all four inclined roofs, forming a stable support in the full range and ensuring the safety of the overall structure.

[0022] In summary, through the structural design, the utility model can increase the installed capacity and improve the power generation efficiency on the premise of ensuring the safety of the overall structure, which is more economical and reasonable.

[0023] 2. The diagonal bracket adopts the structure of upper and lower inclined beams + support columns, with a more stable structure and better applicability, forming a stable support for the photovoltaic modules.

[0024] In addition, the advantage of the diagonal bracket adopting the upper and lower double-inclined beam structure is that the height of the support column can be adjusted. For example, the height of the support column increases one by one from the lower side to the upper side, or the height of the support column decreases one by one from the lower side to the upper side. In this way, the inclination angle of the inclined beam can be changed by adjusting the height of the support column, solving the problem that the ridge height is too high to cross, and having a better force form than the traditional short diagonal brace directly connected to the hook, with a smaller bending moment value at the bottom of the hook, and also being able to better cope with the sunlight angles in different regions.

[0025] 3. By setting the lower support component, the force exerted by the diagonal bracket on the first inclined roof can be shared, and the number of support hook components can also be correspondingly reduced, reducing the impact of the installation of the diagonal bracket on the first inclined roof and reducing the risk of leakage.

[0026] 4. Due to the excessive overhang of the upper inclined beam longitudinally on the upper side, the triangular structure of the lateral bracket forms a support for the upper side of the upper inclined beam longitudinally, meeting the deflection requirements of the upper inclined beam, and at the same time being beneficial to increasing the resistance to out-of-plane instability and enhancing the overall stability.

[0027] 5. The diagonal bracket and the lateral bracket are installed by using the support hook assembly. The support hook assembly is pre-set on the roof surface, and then the diagonal bracket and the lateral bracket are fixed, which is convenient and fast for installation. Moreover, the bottoms of the diagonal bracket and the lateral bracket are higher than the diagonal roof surface. For a roof with tiles, it can avoid damaging the tiles.

[0028] 6. For a house type with transverse platforms on both transverse sides of the roof, a side-span support assembly is provided between the diagonal bracket and the transverse platform. By setting the side-span support assembly, the force exerted by the lateral bracket on the second diagonal roof surface can be shared, and the number of support hook assemblies can be correspondingly reduced, thereby reducing the impact on the second diagonal roof surface caused by the installation of the lateral bracket and reducing the risk of water leakage. Of course, for a four-sided diagonal roof house type without east-west platforms, the side-span support assembly can be cancelled.

[0029] These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and the drawings.

[0039] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0040] Those skilled in the art can understand that, without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0041] The terms used in the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. For example, the terms indicating orientation or positional relationship such as "upper", "lower", "longitudinal", "transverse", etc. are only based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model.

[0042] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact of the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is lower than that of the second feature.

[0043] Furthermore, terms such as "first", "second", etc. are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0044] In this embodiment, the photovoltaic power station is mainly installed on houses in the scenario of four-sided inclined roofs. Referring to Figure 1 As shown, the roof of the house 5 includes two first inclined roofs 51 symmetrically arranged on both longitudinal sides (taking the common north-south facing house as an example, that is, the north-south slope inclined roofs), and two second inclined roofs 52 symmetrically arranged on both transverse sides (taking the common north-south facing house as an example, that is, the east-west slope inclined roofs). In addition, Figure 1 As shown in a certain house type, longitudinal platforms 53 are provided on both longitudinal sides of the roof, and transverse platforms 54 are provided on both transverse sides. For another house type, platforms may not be provided around the roof.

[0045] As Figures 2 to 7 shown, for Figure 1 the scenario of four-sided inclined roofs shown, this embodiment provides a photovoltaic module installation structure with full coverage on the four-sided inclined roofs. The photovoltaic module installation structure includes two diagonal brackets 1 symmetrically arranged on both longitudinal sides, and the two diagonal brackets 1 integrally cover the spaces above the two first inclined roofs 51 and the two second inclined roofs 52. The diagonal brackets 1 are fixed on the first inclined roofs 51, and lateral brackets 3 are provided between the diagonal brackets 1 and the second inclined roofs 52.

[0046] The present utility model aims at the problem that the four-sided inclined roofs cannot be fully covered (the east-west slopes cannot be reasonably utilized), and provides a relatively reasonable structural form. In the above technical solution, two diagonal brackets are correspondingly arranged on both longitudinal sides, and the two diagonal brackets integrally cover the spaces above the two first inclined roofs (the south slope inclined roof and the north slope inclined roof) and the two second inclined roofs (the east slope inclined roof and the west slope inclined roof), so as to utilize the spaces above the four inclined roofs, realize the simultaneous laying of photovoltaic modules on the four slopes, and increase the power generation area.

[0047] And the two diagonal brackets are equivalent to forming two complete installation slopes, converting the areas where the east-west slopes cannot be laid into the north-south double-slope form, combining with the original installation slopes above the south slope inclined roof as a whole. The conversion structural form of the east-west slopes is more reasonable, and compared with the series connection of the east-west slopes and the mixed connection with the north-south slopes, the power generation efficiency is improved.

[0048] Since the photovoltaic modules cover the entire roof, blocking direct sunlight from hitting the roof and forming a photovoltaic heat insulation layer, it not only effectively protects the roof surface but also can reduce the indoor temperature by 3°C - 5°C, effectively alleviating the stuffiness of the house on hot summer days.

[0049] Secondly, the two diagonal brackets are installed independently. If the ridge is low or there is no ridge, they can extend above the ridge. If the ridge is high, a space can also be formed between the two diagonal brackets to avoid the high ridge, so it can adapt to more house types.

[0050] Finally, the diagonal bracket is fixed to the first inclined roof surface, and a lateral bracket is provided between the diagonal bracket and the second inclined roof surface. Thus, the diagonal bracket is fixed above all four inclined roof surfaces to form a full-range stable support and ensure the safety of the overall structure.

[0051] In summary, through the structural design, the utility model can increase the installed capacity, improve the power generation efficiency, and be more economical and reasonable on the premise of ensuring the safety of the overall structure.

[0052] To fix the diagonal bracket to the first inclined roof surface and the lateral bracket to the second inclined roof surface, support hook assemblies 4 are installed on both the first inclined roof surface 51 and the second inclined roof surface 52. The support hook assembly on the first inclined roof surface is connected to the diagonal bracket 1, and the support hook assembly on the second inclined roof surface is connected to the lateral bracket 3. The number of support hook assemblies can be designed according to the installation requirements to ensure structural safety. There is also a solution in the market to directly penetrate the inclined roof with a column and extend it to the flat roof to install expansion bolts for fixation. However, there is a problem of holes when penetrating the roof, and there is a risk of water leakage during the rainy season. In this embodiment, the support hook assembly is directly fixed to the inclined roof to avoid the water leakage risk caused by penetrating the roof.

[0053] As Figure 3 shown, in one of the embodiments, the diagonal bracket 1 includes a plurality of lower inclined beams 11 arranged side by side in the transverse direction and a plurality of upper inclined beams 12 arranged side by side in the transverse direction. The upper inclined beams 12 are correspondingly arranged above the lower inclined beams 11, and a plurality of support columns 13 are provided between the lower inclined beams 11 and the upper inclined beams 12. The lower inclined beams 11 are fixed to the first inclined roof surface 51. The diagonal bracket adopts a structure of upper and lower inclined beams + support columns, with a more stable structure and better applicability, forming a stable support for the photovoltaic modules.

[0054] In addition, the advantage of the diagonal bracket adopting the upper and lower double inclined beam structure is that the height of the support column can be adjusted. It can be understood that, alternatively, the height of the support column 13 gradually increases from the lower side to the upper side, or the height of the support column 13 gradually decreases from the lower side to the upper side. In this way, the height of the support column can be adjusted to change the inclination angle of the inclined beam, solve the problem that the ridge height is too high to cross, and has a better force form than the traditional short diagonal brace directly connected to the hook, with a smaller bending moment value at the bottom of the hook, and can also better cope with the sunlight angles in different regions. Of course, it can be understood that a single inclined beam structure can also be adopted.

[0055] It can be understood that other changes can also be made to the specific structure of the diagonal bracket.

[0056] To further ensure structural safety, a lower support assembly 2 is provided between the longitudinal lower end of the diagonal support 1 and the building. In this embodiment, longitudinal platforms 53 are provided on both longitudinal sides of the roof. The longitudinal lower end of the upper inclined beam 12 is longer than that of the lower inclined beam 11. The lower support assembly 2 includes a lower vertical column 21 and a lower diagonal brace 22. The lower end of the lower vertical column 21 is fixed to the longitudinal platform 53. The lower vertical column 21 is connected to the end of the lower inclined beam and its upper end is connected to the upper inclined beam 12. One end of the lower diagonal brace 22 is connected to the lower vertical column 21 and the other end is connected to the upper inclined beam 12. Specifically, the lower vertical column is respectively hinged to the upper inclined beam, the lower inclined beam and the lower diagonal brace through a hinge seat. Both ends of the lower diagonal brace are respectively hinged to the lower vertical column and the upper inclined beam through a hinge seat. The bottom of the lower vertical column is bolted with a column base 23, and the column base is fixed to the longitudinal platform 53 through bolts. The support hook assembly on the first inclined roof is connected to the lower inclined beam of the diagonal support. By providing the lower support assembly, the force exerted by the diagonal support on the first inclined roof can be shared, and the number of support hook assemblies can be correspondingly reduced, reducing the impact of the installation of the diagonal support on the first inclined roof and reducing the risk of water leakage.

[0057] It can be understood that for scenarios without longitudinal platforms, a lower support assembly can also be provided, and the lower support assembly can also be fixed to the wall by means of a bracket.

[0058] In one of the embodiments, the lateral support 3 includes a side inclined beam 31 extending along the inclination direction of the second inclined roof, a side vertical column 32 perpendicular to the side inclined beam, and a side diagonal brace 33 connecting the side inclined beam and the side vertical column. The side inclined beam 31 is fixed to the second inclined roof 52. Specifically, both ends of the side vertical column 32 are respectively hinged to the side inclined beam and the diagonal support through a hinge seat. Both ends of the side diagonal brace 33 are respectively hinged to the side inclined beam and the side vertical column through a hinge seat. The support hook assembly on the second inclined roof is connected to the side inclined beam of the lateral support. Since the overhang on the longitudinal upper side of the upper inclined beam is too large, the triangular structure of the lateral support forms a support for the longitudinal upper side of the upper inclined beam, meeting the deflection requirements of the upper inclined beam. At the same time, it is beneficial to increase the resistance to out-of-plane instability and enhance the overall stability.

[0059] It can be understood that the specific structure of the lateral support can also be changed in other ways.

[0060] Referring to the prior art, such as Figure 5As shown, the support hook assembly 4 includes a first fixing member 41 fixed to the sloping roof and a hook connected to the first fixing member. The first fixing member 41 is fixed to the sloping roof by a second fixing member 42, and the second fixing member can be a U-bolt. The first fixing member 41 is L-shaped and includes a first inclined section extending obliquely and a first upward bending section bent upward obliquely from one side of the first inclined section. The first inclined section is located below the roof tiles and is fixed to the sloping roof by a U-bolt. The first upward bending section passes through the gap between the roof tiles, and the first upward bending section is connected to the hook. The hook includes an upper hook 44 and a lower hook 43. The lower hook 43 includes a second inclined section extending obliquely along the sloping roof, a second upward bending section bent upward obliquely from the upper side of the second inclined section, and a first downward bending section bent downward obliquely from the lower side of the second inclined section. The first downward bending section is connected to the first upward bending section by a fixing bolt. The upper hook 44 includes a third inclined section extending obliquely along the sloping roof, a fixing ear bent upward from the side of the lower side of the third inclined section, and a second downward bending section bent downward obliquely from the upper side of the third inclined section. The second downward bending section is connected to the second upward bending section by a fixing bolt, and a kidney-shaped hole can be provided on the fixing ear. For the support hook assembly on the first sloping roof, the kidney-shaped hole is connected to the lower inclined beam of the inclined support by a fixing bolt. For the support hook assembly on the second sloping roof, the kidney-shaped hole is connected to the side inclined beam of the inclined support by a fixing bolt. During installation, the support hook assembly is pre-set on the roof, and then the inclined support and the lateral support are fixed, which is convenient for quick installation. Moreover, the bottom of the inclined support and the lateral support is higher than the sloping roof, so as to avoid crushing the roof tiles for a roof with tiles.

[0061] In addition, purlins 14 are provided on the inclined support 1, and the purlins 14 extend transversely and are connected to the upper inclined beam 12 by bolts. As Figure 6 shown, referring to the prior art, the photovoltaic module is connected to the purlin 14 by a pressing block assembly 15, and the pressing block assembly 15 includes an upper pressing block, a lower pressing block, and a pressing block bolt connecting the upper pressing block and the lower pressing block.

[0062] For the scenario where the roof has transverse platforms on both transverse sides, as Figure 7As shown, there is a side-span support assembly between the diagonal support 1 and the transverse platform 54. The side-span support assembly includes a first side-span support 6 and a second side-span support 7. The first side-span support 6 is arranged at the longitudinal middle position, and the two second side-span supports 7 are symmetrically arranged on the longitudinal two sides of the first side-span support 6. Specifically, the first side-span support 6 includes two first side-span columns 61 arranged side by side longitudinally and a strengthening rod 62 connecting the two first side-span columns. The lower ends of the two first side-span columns are fixed to the transverse platform 54 through column feet, and the upper ends are respectively connected to the two diagonal supports 1 through hinge seats. The second side-span support 7 includes a second side-span column 71 and two side-span diagonal braces 72 arranged on the longitudinal two sides of the first side-span column. The lower end of the second side-span column is fixed to the transverse platform through a column foot, one end of the side-span diagonal brace is connected to the second side-span column through a hinge seat, and the other end is connected to the diagonal support through a hinge seat. By setting the side-span support assembly, the acting force of the lateral support on the second inclined roof can be shared, the number of support hook assemblies can be correspondingly reduced, the influence of the installation of the lateral support on the second inclined roof can be reduced, and the leakage risk can be reduced.

[0063] It can be understood that other changes can also be made to the specific structure of the side-span support assembly.

[0064] It can be understood that for the scenario without a transverse platform, the setting of the side-span support assembly can also be cancelled.

[0065] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
