Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a double-slope roof photovoltaic power station. [Background Technology]

[0002] Currently, the common design for photovoltaic (PV) power stations on gable roofs involves placing the PV modules flush against the sloping roof surface. For rooftops with high ridges, trusses are used to elevate the PV modules. Refer to Chinese utility model patent CN 221177593U, the applicant's prior patent, which discloses a PV system installed on a gable roof. This system includes two inclined PV supports mounted on either side of the ridge and PV modules mounted on these supports. The inclined PV supports are equipped with inclined support trusses, the bottom of which is fixed to the sloping roof surface. The inclined support trusses have longitudinally extending upper inclined beams, and these upper inclined beams have elevated sections extending above the ridge. The elevated sections of the inclined PV supports on both sides of the ridge have cross-fixed elevated fixing parts. However, in existing gable roof PV power stations, the power generation efficiency is very low on the north-facing slope of the gable roof. [Utility Model Content]

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a photovoltaic power station installed on a single slope of a double-sloped roof, thereby solving the problem of limited power generation efficiency of photovoltaic power stations on double-sloped roofs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A photovoltaic power station with a single-slope installation on a double-slope roof is disclosed. The double-slope roof includes a first sloping roof and a second sloping roof set on opposite sides of the roof ridge. The photovoltaic power station includes a photovoltaic support frame and photovoltaic modules. The photovoltaic support frame includes a first single-slope support frame installed on the first sloping roof and extending longitudinally upward to above the second sloping roof, and a second support frame installed on the second sloping roof and supported below the first single-slope support frame. The first single-slope support frame is provided with a single-slope mounting surface for installing photovoltaic modules.

[0006] Preferably, the first single-slope support includes a truss.

[0007] Preferably, the truss includes an upper chord, a lower chord, and a web member disposed between the upper chord and the lower chord. The first single-slope support also includes a short support rod disposed between the bottom of the truss and the first sloping roof, and the short support rod is disposed at the connection node between the lower chord and the web member.

[0008] Preferably, the second support includes an inclined support rod extending along the second sloping roof, an edge sealing support rod connecting the downward inclined end of the inclined support rod to the upward inclined end of the first single-slope support, and an inner support rod disposed within the triangle formed by the inclined support rod, the edge sealing support rod, and the first single-slope support.

[0009] Preferably, the second support also includes a short support column supported between the inclined support rod and the second sloping roof.

[0010] Preferably, the photovoltaic support is surrounded by a color steel tile enclosure structure, which includes a horizontally extending mounting beam and color steel tiles fixed to the mounting beam.

[0011] Preferably, the mounting beam is fixed to a row of columns, and a diagonal support rod is provided between two columns on the side.

[0012] Preferably, the photovoltaic support also includes a number of bottom beams spaced longitudinally, the bottom beams extending laterally and connecting the first single-slope support and the second support.

[0013] Preferably, the bottom beam corresponding to the lowest side of the first single-slope support and the second support is connected with tie bars, and a fixing plate is installed on the wall below the first sloping roof and the second sloping roof, and the fixing plate is fixed to the tie bars.

[0014] Preferably, a waterproof structure is provided between two adjacent photovoltaic modules, the waterproof structure including a waterproof strip; and / or, a crossbeam is installed on the single-slope mounting surface, and the photovoltaic module is installed on the crossbeam using a pressure plate bolt assembly.

[0015] The present invention adopts the above technical solution and has the following beneficial effects:

[0016] 1. The photovoltaic support system includes a first single-slope support installed on the first sloping roof and extending longitudinally upward to the top of the second sloping roof, and a second support installed on the second sloping roof and supported below the first single-slope support. The first single-slope support is provided with a single-slope mounting surface for installing photovoltaic modules, thus forming a single-slope structure on the double-sloping roof to install photovoltaic modules. Compared with the original installation of photovoltaic modules on the first sloping roof and the second sloping roof respectively, it can solve the problem of low power generation on the north slope of the sloping roof.

[0017] 2. The first single-slope support adopts a truss structure. The advantage of the truss is that the members mainly bear tension or compression, which can make full use of the material, save materials, reduce the structural weight, and raise the photovoltaic modules.

[0018] 3. The second support structure includes a diagonal support rod extending along the second sloping roof, an edge-sealing support rod connecting the downward end of the diagonal support rod to the upward end of the first single-slope support, and an inner support rod located within the triangle formed by the diagonal support rod, the edge-sealing support rod, and the first single-slope support. Thus, the second support structure forms a triangular support structure, further supported by the inner support rod, resulting in a stable structure and effective support for the first single-slope support.

[0019] 4. The photovoltaic support structure is enclosed by corrugated steel sheets, which can better protect the farmers' roofs and solve the problem of waterproofing the sloping roofs, making it more acceptable to farmers.

[0020] 5. Since the installation beam is fixed on a row of columns, and there are diagonal support rods between the two side columns, the overall structure of the color steel tile enclosure can be guaranteed to be solid.

[0021] 6. The bottom beam can connect the truss into a whole and the second support into a whole, making the structure more stable.

[0022] 7. Tie bars are connected to the bottom beams that are connected to the lowest side of the first single-slope support and the second support. Fixing plates are installed on the walls below the first and second sloping roofs. The fixing plates are fixed to the tie bars, which fixes the bottom beams and avoids setting fixing points on the roof, thus reducing the risk of roof leakage.

[0023] 8. Because the first single-slope support adopts a truss scheme, the photovoltaic modules are raised, and the modules can be installed with pressure plates. The gap between the modules is reduced from 20mm to 6mm. It can be combined with the scheme of setting adhesive strips and applying sealant between the modules, which makes construction convenient and prevents water leakage.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

[0036] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0037] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0038] The terminology used in this invention is for the purpose of describing specific embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," "rear," "south," and "north," which indicate orientation or positional relationships, are based solely on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0041] The photovoltaic power station in this embodiment is mainly designed for double-sloped roof scenarios, referring to... Figures 1 to 9 As shown, in a building 4 with a double-sloped roof, the roof is provided on both sides of the ridge, usually the north and south sides (or the front and back, since the house usually faces south). Here, the south sloping roof is designated as the first sloping roof 41 and the north sloping roof as the second sloping roof 42.

[0042] This embodiment provides a photovoltaic power station installed on a single slope of a double-sloped roof. The photovoltaic power station includes a photovoltaic support frame and photovoltaic modules 2. The photovoltaic support frame includes a first single-slope support 11 installed on the first sloping roof and extending longitudinally upwards to above the second sloping roof, and a second support 12 installed on the second sloping roof and supported below the first single-slope support. The first single-slope support has a single-slope mounting surface 112 for installing the photovoltaic modules. Therefore, a single-slope structure is formed on the double-sloped roof to install the photovoltaic modules. Compared with the original method of installing photovoltaic modules on the first sloping roof and the second sloping roof separately, this method can solve the problem of low power generation on the north slope of the sloping roof.

[0043] In some embodiments, the first single-slope support 11 includes a truss 111. The truss structure can refer to existing technology, and the truss 111 includes an upper chord, a lower chord, and web members disposed between the upper and lower chords. Further, the first single-slope support also includes short support rods disposed between the bottom of the truss and the first sloping roof, and the short support rods are located at the connection node between the lower chord and the web members. The first single-slope support adopts a truss structure. The advantages of a truss are that the members mainly bear tensile or compressive forces, which can fully utilize the material, save materials, reduce structural weight, and raise the photovoltaic modules.

[0044] In some embodiments, the second support 12 includes a diagonal support rod 121 extending along the second sloping roof, an edge-sealing support rod 122 connecting the downward diagonal end of the diagonal support rod to the upward diagonal end of the first single-slope support, and an inner support rod 123 disposed within the triangle formed by the diagonal support rod, the edge-sealing support rod, and the first single-slope support. Furthermore, the second support also includes a short support column 124 supported between the diagonal support rod and the second sloping roof. The second support as a whole forms a triangular support structure, internally supported by the inner support rod, resulting in a stable structure and good support effect for the first single-slope support.

[0045] Existing solutions for enclosing photovoltaic roofs with corrugated steel sheets are typically installed on flat roofs. For customers who wish to enclose sloping roofs with corrugated steel sheets as well, there is currently no suitable solution. In this embodiment, the photovoltaic support structure is surrounded by a corrugated steel sheet enclosure. This enclosure includes horizontally extending mounting beams 31 and corrugated steel sheets 3 fixed to the mounting beams. Specifically, the corrugated steel sheets are fixed to the mounting beams using self-tapping screws 32. The photovoltaic support structure is enclosed by corrugated steel sheets, forming a fully enclosed structure with the photovoltaic modules. This provides better protection for farmers' roofs, solves the problem of roof leaks, and is more readily accepted by farmers.

[0046] In addition, the photovoltaic support structure also includes several bottom beams 13 spaced longitudinally. These bottom beams 13 extend laterally and connect the first single-slope support and the second support. Specifically, for the first single-slope support, the bottom beams are fixedly connected to the lower chord of the truss; for the second support, the bottom beams are fixedly connected to the diagonal support rods. The bottom beams connect the truss into a single unit and the second support into a single unit, resulting in a more stable structure.

[0047] like Figure 4 and Figure 5 As shown, the mounting beam 31 is fixed to a row of columns, and a diagonal support rod 14 is provided between the two side columns. For the north facade, the northernmost web member of the truss 111 and the edge support rod are positioned correspondingly and can be used as columns. For the south facade, the southernmost web member of the truss 111 can be directly used as a column.

[0048] like Figure 6 As shown in the diagram of the first single-slope support, tie bars 15 are connected to the bottom beams that connect to the lowest side of the first and second single-slope supports. Fixing plates 16 are installed on the walls below the first and second sloping roofs, and the fixing plates are fixed to the tie bars. Fixing the bottom beams avoids setting fixing points on the roof, reducing the risk of roof leakage.

[0049] like Figure 7As shown, in order to install corrugated steel sheets for enclosure on the east and west sides, a row of columns 33 is fixed on the outside of the parapet wall 43 on the east and west sides. The bottom of the columns is fixed to the bottom longitudinal beam 34, and the bottom longitudinal beam is fixed to the parapet wall with angle steel 35 and bolts.

[0050] Currently, photovoltaic modules installed on gable roofs are all installed using pre-fitted blocks, which leaves gaps between the modules and makes the roof prone to leaks. For example... Figure 1 , Figure 8 and Figure 9 As shown, in this embodiment, a crossbeam 113 is installed on the single-slope mounting surface 112. The photovoltaic modules are installed on the crossbeam using a pressure plate bolt assembly 21, and a waterproof structure is provided between adjacent photovoltaic modules. The pressure plate bolt assembly includes a pressure plate pressed against the C-side of the photovoltaic module frame and a fastener connecting the pressure plate to the crossbeam. The fastener is a U-bolt, which hugs the crossbeam and connects to the pressure plate. The U-bolt includes a U-shaped threaded rod hugging the crossbeam, with the opening of the U-shaped threaded rod facing upwards and the head passing through a fixing hole on the pressure plate and connected to a nut. The waterproof structure includes a waterproof strip 22, which is located in the lower middle part of the gap between adjacent photovoltaic modules. The waterproof structure also includes waterproof adhesive 23 located above the waterproof strip. The waterproof strip is a prefabricated part, while the waterproof adhesive needs to be poured on-site. Because the first single-slope support adopts a truss design, the photovoltaic modules are raised, and the modules can be installed with pressure plates. The gap between the modules is reduced from 20mm to 6mm. This can be combined with the solution of setting adhesive strips and applying sealant between the modules, making construction convenient and leak-proof.

[0051] The aforementioned short support rods and short support columns are fixed as follows: a fixed beam is provided on the sloping roof, and the lower ends of the short support rods and short support columns are fixed to the fixed beam, while the upper ends are fixed to the lower chord and the diagonal support rod.

[0052] Preferably, the various rods, beams and columns mentioned above can be made of square tubing, and the specifications and models can be selected. Since they are standard parts, the cost can be reduced. Of course, other profiles can be used as substitutes.

[0053] 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.
