Description

Technical field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a rooftop photovoltaic power station installation structure. [Background Technology]

[0002] Existing photovoltaic racks installed on sloping roofs have support points at the bottom of the support columns supporting the inclined beams. The support nodes are supported on the tiles, but this only works when the inclined beams are parallel to the sloping roof. If there is installation deviation or other conditions that cause the two to be non-parallel, the support nodes will not be in good contact with the roof tiles, such as single-point contact. The load will be concentrated on the roof tiles, which may easily crush the roof tiles and cause roof leaks. [Utility Model Content]

[0003] In view of the deficiencies in the existing technology, the technical problem to be solved by the present invention is to provide a photovoltaic bracket installed overhead on a sloping roof, which solves the problem of poor contact between the existing support nodes and roof tiles, resulting in broken tiles and rain leakage.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solution: a photovoltaic bracket installed overhead on a sloping roof, comprising an inclined beam extending longitudinally along the sloping roof and a plurality of supporting columns arranged below the inclined beam and distributed at intervals along the longitudinal direction of the sloping roof, the sloping roof is paved with load-bearing tile supports that have both tile and load-bearing functions, the lower ends of the supporting columns are hinged to the load-bearing tile supports, and the upper ends are hinged to the inclined beam.

[0005] Preferably, the load-bearing tile support includes a load-bearing tile laid on the sloping roof and a lower hinged member provided above the load-bearing tile, and the lower hinged member is hinged to the lower end of the supporting column.

[0006] Preferably, the lower hinged member includes two vertical plates, and the two vertical plates are correspondingly provided with hinge holes, the hinge holes are connected with hinge bolts, and the hinge bolts are hinged to the lower ends of the support columns.

[0007] Preferably, the load-bearing tile support is a steel part; and / or the load-bearing tile and the lower hinge are welded into an integral structure.

[0008] Preferably, an upper hinge is installed on the oblique beam, and the upper end of the supporting column is hinged to the upper hinge.

[0009] Preferably, the upper hinged member comprises two L-shaped plates, a first side of the L-shaped plate is connected to the oblique beam via a fixing bolt, and a second side is connected to the hinge bolt.

[0010] Preferably, the heights of the plurality of supporting columns gradually increase from the longitudinal lower side to the upper side to raise the height of the longitudinal upper end of the inclined beam; and / or the inclined beam and / or the supporting columns are made of U-shaped steel.

[0011] Preferably, photovoltaic brackets are installed on the sloping roofs on opposite sides of the house, and the sloping beams of the two photovoltaic brackets are hingedly connected through upper hinges.

[0012] Preferably, the longitudinal lower side of the inclined beam is provided with a cantilevered section extending beyond the longitudinal lower edge of the inclined roof, and a cantilevered support assembly is provided between the cantilevered section and the wall.

[0013] Preferably, the cantilever support assembly includes two diagonal support supports fixed vertically to the wall, a first diagonal support rod whose lower end is hinged to the lower diagonal support support and whose upper end is hinged to the cantilever section, and a second diagonal support rod whose lower end is hinged to the upper diagonal support support and whose upper end is hinged to the first diagonal support rod.

[0014] The utility model adopts the above technical solution, which has the following beneficial effects:

[0015] 1. The sloping roof is equipped with a load-bearing tile support that has both tile and load-bearing functions. It can be used as a tile or as the bottom support of the supporting column, and can replace the original roof tiles. The load-bearing tile support can be made of high-strength materials with high strength and long durability. It can solve the problem of installing a sloping roof photovoltaic power station on the existing roof tiles that cannot bear loads, and can also avoid the situation where broken tiles leak due to single-point contact between the support node and the roof tiles.

[0016] Since the load-bearing tile supports can replace the original roof tiles, there is no need to lay waterproof membranes and no need to consider the problem of broken tiles under load, which can save subsequent operation and maintenance costs.

[0017] In addition, the lower end of the support column is hinged to the load-bearing tile support, and the upper end is hinged to the inclined beam, so the support column can be fine-tuned in angle, which is convenient for use on sloping roofs and ensures stable support for the inclined beam.

[0018] 2. Since the load-bearing tile supports serve as both tiles and the bottom support of the supporting columns, the load-bearing tiles replace the original roof tiles, and the lower hinge is hinged to the lower end of the supporting column.

[0019] 3. The two vertical plates of the lower hinge are provided with corresponding hinge holes, and the hinge holes are connected with hinge bolts. The hinge bolts are hinged to the lower ends of the supporting columns, which not only hinge the load-bearing tile support to the supporting columns, but also ensure the horizontal position of the supporting columns.

[0020] 4. The load-bearing tile support is made of steel, which is welded into an integrated structure with the load-bearing tile and the lower hinge, so it has high strength and long durability.

[0021] 5. The two L-shaped plates of the lower hinge have their first side connected to the inclined beam through fixing bolts, and the second side connected to the hinge bolts, so that the support column can fine-tune the angle relative to the inclined beam.

[0022] 6. As the height of several supporting columns increases gradually from the lower side to the upper side, the height of the upper end of the inclined beam is raised. On the one hand, a photovoltaic insulation layer is formed between the photovoltaic modules and the roof. On the other hand, since the upper end of the inclined beam is relatively high, the upper end of the inclined beam can be extended upward over the roof ridge, which is suitable for houses with high roof ridges.

[0023] 7. Photovoltaic brackets are installed on the sloping roofs on both sides of the house, and the inclined beams of the two photovoltaic brackets are hinged through the upper hinges, so that the photovoltaic brackets on both sides are connected as a whole, and the structure is stable and reliable.

[0024] Photovoltaic modules are installed on photovoltaic brackets, and photovoltaic modules can be installed on both sloping roofs. In this way, all houses with double-sloped roofs with ridges can be utilized to achieve coverage of more room types, and laying photovoltaic panels on double slopes will not cause waste of area.

[0025] 8. The cantilevered section on the longitudinal underside of the inclined beam increases the area of the photovoltaic module and improves power generation efficiency. Furthermore, a cantilevered support assembly is provided between the cantilevered section and the wall to secure the cantilevered section. This ensures that the top, middle, and bottom of the photovoltaic support are all securely fixed.

[0026] 9. Since the cantilever support assembly is provided with a first oblique support rod and a second oblique support rod fixed to the first oblique support rod, a stable triangular support is formed, thereby improving the reliability of the cantilever section support of the photovoltaic bracket.

[0027] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0040] The photovoltaic power station in this embodiment is installed on a sloping roof, and is designed for a scenario where roof tiles are laid on the roof, especially a double-slope sloping roof with a ridge.

[0041] Reference Figures 1 to 5 As shown, for a double-slope sloping roof building 2 with a ridge, a sloping roof 21 is provided in the north-south direction of the roof, a ridge 22 is provided in the middle, and walls 23 are provided on the north and south sides. This embodiment provides a photovoltaic bracket 1 installed overhead on a sloping roof, a photovoltaic module 100 is installed on the photovoltaic bracket 1, and the photovoltaic bracket 1 includes an inclined beam 13 extending longitudinally along the inclination direction of the sloping roof 21 and a plurality of supporting columns 15 provided below the inclined beam 13 and spaced longitudinally along the sloping roof 21. The sloping roof 21 is paved with a load-bearing tile support 16 having both tile and load-bearing functions. The lower end of the support column 15 is hinged to the load-bearing tile support 16, and the upper end is hinged to the inclined beam 13.

[0042] The sloping roof is equipped with a load-bearing tile support that has both tile and load-bearing functions. It can be used as a tile or as the bottom support of the supporting column. It can replace the original roof tiles. The load-bearing tile support can be made of high-strength material with high strength and long durability. It can solve the problem of installing a sloping roof photovoltaic power station on the existing roof tiles that cannot bear loads, and can also avoid the situation where broken tiles leak due to single-point contact between the support node and the roof tiles.

[0043] Since the load-bearing tile supports can replace the original roof tiles, there is no need to lay waterproof membranes and no need to consider the problem of broken tiles under load, which can save subsequent operation and maintenance costs.

[0044] In addition, the lower end of the support column is hinged to the load-bearing tile support, and the upper end is hinged to the inclined beam, so the support column can be fine-tuned in angle, which is convenient for use on sloping roofs and ensures stable support for the inclined beam.

[0045] like Figure 4 and Figure 5 Specifically, the load-bearing tile support 16 comprises a load-bearing tile 161 installed on the sloping roof 21 and a lower hinge 162 positioned above the load-bearing tile. The lower hinge 162 is hingedly connected to the lower end of the support column 15. Because the load-bearing tile support serves both as a tile and as the bottom support for the support column, the load-bearing tile replaces the original roof tile, while the lower hinge is hingedly connected to the lower end of the support column. Furthermore, the load-bearing tile support 16 is made of steel, with the load-bearing tile 161 and the lower hinge 162 welded together to form a single structure, resulting in high strength and durability.

[0046] like Figure 5 As shown, the lower hinge member 162 further comprises two vertical plates, each of which has corresponding hinge holes. These hinge holes are connected to hinge bolts, which are hinged to the lower ends of the support columns. This not only hinges the load-bearing tile support to the support columns, but also ensures the horizontal position of the support columns.

[0047] In this embodiment, an upper hinge 14 is mounted on the oblique beam 13, and the upper end of the support column 15 is hinged to the upper hinge 14. The upper hinge 14 comprises two L-shaped plates, the first side of the L-shaped plate being connected to the oblique beam 13 via a fixing bolt, and the second side being connected to a hinge bolt, so that the support column can fine-tune its angle relative to the oblique beam.

[0048] Furthermore, the several support columns 15 gradually increase in height from the lower side to the upper side, thereby raising the height of the upper end of the inclined beam. This not only forms a photovoltaic insulation layer between the photovoltaic modules and the roof, but also, due to the higher upper end of the inclined beam, it can extend upward above the roof ridge, making it suitable for houses with high roof ridges, rather than just conventional double-sloped roofs without a ridge. Furthermore, both the inclined beam 13 and the support columns 15 can be made of U-shaped steel.

[0049] Here, photovoltaic brackets are installed on the sloping roofs on both sides of the house. Photovoltaic panels can be installed on both sloping roofs, so that all houses with double-sloped roofs with ridges can be utilized to achieve coverage of more house types, and laying photovoltaic panels on the double slopes will not cause waste of area; any orientation can better cope with changes in sunlight angles and adapt to a larger azimuth range. Figure 2 As shown, the oblique beams 13 of the two photovoltaic supports are cross-shaped in a herringbone shape, and the intersection is located above the roof ridge 22 and is hinged by the upper hinge 14. Thus, the photovoltaic supports on both sides are connected as a whole, and the structure is stable and reliable.

[0050] like Figure 3 As shown, in this embodiment, the longitudinal lower side of the inclined beam 13 is provided with a cantilever section extending beyond the longitudinal lower edge of the inclined roof, and a cantilever support assembly is provided between the cantilever section and the wall. The cantilever support assembly includes two diagonal support brackets 17 fixed vertically to the wall, a first diagonal support rod 18 hinged at its lower end to the lower diagonal support bracket and hinged at its upper end to the cantilever section, and a second diagonal support rod 19 hinged at its lower end to the upper diagonal support bracket and hinged at its upper end to the first diagonal support rod. The cantilever section can increase the area of the photovoltaic module and improve power generation efficiency. In addition, a cantilever support assembly is provided between the cantilever section and the wall to fix the cantilever section. In this way, it forms a stable support for the photovoltaic module in conjunction with the support column. In addition, the upper, middle and lower parts of the photovoltaic bracket are all fixed, ensuring reliable fixation. Because the cantilever support assembly is provided with the first diagonal support rod 18 and the second diagonal support rod 19 fixed to the first diagonal support rod, a stable triangular support is formed, which improves the reliability of the support for the cantilever section. The diagonal support 17 is connected to the expansion bolts, and the expansion bolts are fixed to the wall.

[0051] In addition, referring to the structure of a common photovoltaic support, a number of cross beams 11 are fixed vertically and crosswise on a number of inclined beams 13 , and the photovoltaic components 100 are installed on the cross beams 11 using a pressing block component 12 .

[0052] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art will understand that the utility model includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the utility model are intended to be included within the scope of the claims.
