Abstract
Description
[Technical Field]
[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a sloping roof double-slope photovoltaic power station. [Background Technology]
[0002] Currently, the installation of photovoltaic modules on double-sloped roofs for residential photovoltaic systems is gradually being promoted, as it does not waste roof space. Common technical solutions include hook-based and overhead installation schemes. Referring to the applicant's prior patent, Chinese utility model patent CN221177593 U, a photovoltaic system installed on a double-sloped roof is disclosed. It includes two inclined photovoltaic brackets corresponding to the sloping roof sides of the ridge and photovoltaic modules installed on the brackets. The inclined photovoltaic brackets have inclined support trusses, the bottom of which is fixed to the sloping roof. The inclined support trusses have longitudinally extending upper inclined beams, and the upper inclined beams have overhead sections extending above the ridge. The overhead sections of the inclined photovoltaic brackets on both sides of the ridge have cross-fixed overhead fixing parts. This system uses a hook-based scheme, with triangular braces between the brackets and the wall. However, conventional hook-based schemes for sloping roofs require removing tiles for installation, affecting the original roof structure and posing a significant risk of subsequent leaks, resulting in low acceptance among farmers. The sloping roof elevated structure is more widely accepted. This structure uses a front-pull, rear-pull configuration and requires triangular bracing on both sides of the building. However, due to the presence of hollow-wall structures in some unique building types, the placement of triangular bracing is limited, thus restricting the development of these properties. [Utility Model Content]
[0003] To address the shortcomings of existing technologies, the present invention aims to provide a sloping roof photovoltaic power station and its installation structure, thereby avoiding the limitation of wall structure that prevents the simultaneous installation of photovoltaic modules on the south and north slopes of the roof.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] An installation structure for a sloping roof photovoltaic power station includes two inclined photovoltaic brackets installed on the front and rear sides of the sloping roof and photovoltaic modules installed on the inclined photovoltaic brackets. Both inclined photovoltaic brackets are provided with cantilever sections extending downwards beyond the outer side of the wall. The cantilever sections are connected to a row of columns, the bottom of which is fixed to the ground. A cantilever bracing structure is provided between the columns and the cantilever sections.
[0006] Preferably, the top of the column is provided with a connecting support, which is hinged to the cantilever section.
[0007] Preferably, the cantilevered bracing structure includes an inclined support rod and inclined support seats connected to both ends of the inclined support rod, with the two inclined support seats respectively hinged to the column and the cantilever section.
[0008] Preferably, the inclined photovoltaic support includes an inclined beam and purlins installed on the inclined beam, and the photovoltaic modules are installed on the purlins using a clamping assembly.
[0009] Preferably, a support column is provided between the inclined beam and the inclined roof, and a fixed beam is provided on the inclined roof. The lower end of the support column is fixed to the fixed beam, and the upper end is fixed to the inclined beam.
[0010] Preferably, the fixed beam is a U-shaped steel with its opening facing downwards at an angle, and the bottom of the support column abuts against the fixed beam at an upward angle and is connected by a first fixing bolt.
[0011] Preferably, the upper end of the support column is provided with a support plate, which supports the bottom surface of the inclined beam and is connected by a second fixing bolt.
[0012] Preferably, the inclined beam of the first inclined photovoltaic bracket extends to below the inclined beam of the second inclined photovoltaic bracket and is hinged by a hinge.
[0013] Preferably, the hinge is an L-shaped structure, including a first side and a second side, wherein the first side is hinged to the inclined beam of the first inclined photovoltaic bracket at the upper inclined end, and the second side is fixed to the inclined beam of the second inclined photovoltaic bracket at the upper inclined end using a third fixing bolt.
[0014] In addition, a type of sloping roof photovoltaic power station is installed using the aforementioned installation structure.
[0015] The present invention adopts the above technical solution and has the following beneficial effects:
[0016] Photovoltaic modules are installed on two inclined photovoltaic (PV) brackets on the north and south sloping roofs, enabling simultaneous installation of PV modules on both the south and north slopes. However, to avoid the limitations imposed by the wall structure, the inclined PV brackets have cantilevered sections extending downwards beyond the outer edge of the wall, connected to a row of columns. Because these cantilevered sections are fixed to the columns within the courtyard, the PV brackets are no longer dependent on the wall for stability. This avoids the limitation of wall structure preventing simultaneous installation of PV modules on both the south and north slopes, allowing for coverage of more house types.
[0017] In addition, the cantilever section of the inclined photovoltaic support can increase the area of the photovoltaic modules, improve power generation efficiency, and facilitate connection with the column.
[0018] Furthermore, the presence of a cantilevered bracing structure between the column and the cantilever section helps to increase the length of the cantilever section and also increases the stability of the column's support for the cantilever section.
[0019] 2. Support columns are installed between the sloping beam and the sloping roof. The fixed beam is laid on the sloping roof. The lower end of the support column is fixed to the fixed beam and the upper end is fixed to the sloping beam. This installation structure allows the sloping photovoltaic bracket to be installed in the air above the roof. It can span the entire roof and no longer needs to use hooks. It can be freed from the roof's restrictions and avoid roof leakage caused by the installation of the photovoltaic structure.
[0020] 3. The inclined beam of the first inclined photovoltaic bracket extends to the lower part of the inclined beam of the second inclined photovoltaic bracket and is hinged together with a hinge, so that the two inclined photovoltaic brackets on the two inclined roofs are fixed as a whole, improving the overall stability.
[0021] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

[0032] The photovoltaic power station in this embodiment is mainly designed for double-sloped roofs and is suitable for some special house types, such as those with hollow-wall structures that lack sufficient strength to accommodate triangular bracing on both sides of the house. (Refer to...) Figures 1 to 3 As shown, a building 6 with a double-sloped roof has sloping roofs 61 on both the north and south (or front and rear) sides, and walls 62 on both sides. This embodiment provides an installation structure for a double-sloped photovoltaic power station, including two inclined photovoltaic brackets 2 installed on the front and rear (usually north-south) sides of the roof, and photovoltaic modules 1 installed on the inclined photovoltaic brackets 2. The inclined photovoltaic brackets 2 have cantilevered sections extending downwards beyond the outer side of the walls. Since the columns cannot be fixed to the walls, a row of columns 22 is connected to the cantilevered sections, with the bottom of the columns 22 installed on the ground. Furthermore, a cantilevered bracing structure is provided between the columns 22 and the cantilevered sections.
[0033] This embodiment adopts the above technical solution and has the following beneficial effects:
[0034] Photovoltaic modules are installed on two inclined photovoltaic (PV) brackets on the north and south sloping roofs, enabling simultaneous installation of PV modules on both the south and north slopes. However, to avoid the limitations imposed by the wall structure, both inclined PV brackets have cantilevered sections extending downwards beyond the outer edge of the wall, connected to a row of uprights. Because these cantilevered sections are fixed to the pillars within the courtyard, the PV brackets are no longer dependent on the wall for stability. This avoids the limitation of wall structure preventing simultaneous installation of PV modules on both the south and north slopes, allowing for coverage of more house types.
[0035] In addition, the cantilever section of the inclined photovoltaic support can increase the area of the photovoltaic modules, improve power generation efficiency, and facilitate connection with the column.
[0036] Furthermore, the presence of a cantilevered bracing structure between the column and the cantilever section helps to increase the length of the cantilever section and also increases the stability of the column's support for the cantilever section.
[0037] Specifically, the top of the column 22 is provided with a connecting support 5, which is hinged to the cantilever section. The connecting support 5 includes a base body connected to the top of the column and a vertical plate on the base body. The base body is nested in the top of the column and can be fixed by bolts or welding. The vertical plate is hinged to the cantilever section by bolts. The cantilever bracing structure includes an inclined support rod 21 and inclined support seats 23 connected to both ends of the inclined support rod. The two inclined support seats 23 are hinged to the column 22 and the cantilever section, respectively. The structure of the inclined support seat connected to the column can be similar to that of the connecting support 5, including a base body and a side plate on the base body. The base body is nested outside the column and can be fixed by bolts or welding. The side plate is hinged to the inclined support rod by bolts. The inclined support seat connected to the cantilever section has an L-shaped structure, including a first side and a second side. The first side is hinged to the upper end of the inclined support rod, and the second side is fixed to the inclined beam by a third fixing bolt. The inclined photovoltaic support 2 includes an inclined beam 11 and purlins 12 installed on the inclined beam. The photovoltaic module 1 is installed on the purlins using a pressure block assembly. The structure of the pressure block assembly can refer to the prior art.
[0038] In addition, a short roof support assembly 3 is provided between the inclined beam 11 and the inclined roof surface. The short roof support assembly 3 includes a support column 32, and a fixed beam 31 is provided on the inclined roof surface. The lower end of the support column is fixed to the fixed beam, and the upper end is fixed to the inclined beam. The fixed beam is a U-shaped steel beam with its opening facing downwards at an angle. The bottom of the support column abuts against the fixed beam at an angle upwards and is connected by a first fixing bolt. A support plate 33 is provided at the upper end of the support column, which supports the bottom surface of the inclined beam and is connected by a second fixing bolt. This installation structure allows the inclined photovoltaic bracket to be installed entirely above the roof, spanning the entire roof surface, eliminating the need for hooks, freeing it from roof constraints, and preventing roof leaks caused by the installation of the photovoltaic structure.
[0039] In some embodiments, the upward-sloping end of the inclined beam of the first inclined photovoltaic bracket extends below the upward-sloping end of the inclined beam of the second inclined photovoltaic bracket and is hinged to it via hinge 4. This fixes the two inclined photovoltaic brackets on the sloping roofs on both sides into a single unit, improving overall stability. Specifically, the hinge 4 has an L-shaped structure, including a first side and a second side. The first side is hinged to the upward-sloping end of the inclined beam of the first inclined photovoltaic bracket, and the second side is fixed to the upward-sloping end of the inclined beam of the second inclined photovoltaic bracket using a third fixing bolt.
[0040] To install the columns, foundations are buried in the ground on the front and rear sides of the house, and the columns are fixed to the foundations with bolts at their bases. Furthermore, the foundations can be either reinforced concrete structures or spiral steel piles.
[0041] Preferably, the inclined beams, purlins, support columns, and diagonal support rods are all made of U-shaped steel, and the uprights are made of square steel tubing. Specifications and models can be selected; since they are standard parts, costs can be reduced. Of course, other profiles can be used as substitutes.
[0042] 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 should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
