Description

[Technical Field]

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

[0002] Double-pitched roofs are quite common in buildings, and currently, installing photovoltaic modules on both sloping sides of the roof has become the mainstream in the market for double-pitched roof photovoltaic power stations. However, this type of building has a significant risk of water leakage. To meet market demand, the applicant developed an M-shaped water channel system to ensure the roof achieves a waterproof effect.

[0003] For the M-type gutter design, when there is a platform at the eaves that needs to be raised, a double-sloping beam solution is generally used. However, this solution uses two sloping beams and the M-type gutter simultaneously, resulting in material waste. Furthermore, the increased elevation requirements lead to greater wind loads and more stringent requirements for scaffolding construction. The added height of the sloping beam also increases the exposed area, making it more susceptible to rainwater erosion. [Utility Model Content]

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a raised installation structure for a rooftop photovoltaic water trough and a rooftop photovoltaic power station, thereby solving the problem of needing to raise the water trough when there is a platform at the eaves and reducing the material cost of raising it.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] First, a raised installation structure for a photovoltaic roof gutter on a sloping roof is provided. Photovoltaic modules are installed on the sloping roof, and a longitudinal water channel is provided between two adjacent photovoltaic modules in the horizontal direction. The raised installation structure for the gutter includes a sloping beam, a crossbeam, and a raised connecting component. The sloping beam extends longitudinally along the sloping roof. The photovoltaic modules and the longitudinal water channel are fixed on the crossbeam. The lower end of the raised connecting component is connected to the sloping beam, and the upper end is connected to the crossbeam.

[0007] Preferably, the lifting connection component includes a first connector, the upper end of which is provided with a crossbeam positioning groove, and the crossbeam is positioned in the crossbeam positioning groove.

[0008] Preferably, the lifting connection component includes a second connector, the lower end of which is provided with a slanted beam positioning groove, and the slanted beam is positioned within the slanted beam positioning groove.

[0009] Preferably, fastening bolts are provided between the crossbeam and the bottom wall of the crossbeam positioning groove, and fastening bolts are provided between the inclined beam and the bottom wall of the inclined beam positioning groove.

[0010] Preferably, the second connector and the inclined beam positioning groove extend along the extension direction of the inclined beam, and fastening bolts are provided on both longitudinal sides of the first connector and between the first connector and the inclined beam.

[0011] Preferably, both the first connector and the second connector are steel sections; and / or, the first connector has a rectangular portion below the beam positioning groove, and the rectangular portion has a rectangular cavity.

[0012] Preferably, multiple lifting connecting components are provided at intervals along the longitudinal extension direction of the inclined beam, and the height of the multiple lifting connecting components gradually increases from the upper longitudinal side to the lower longitudinal side, thereby raising the lower longitudinal end of the inclined beam.

[0013] Preferably, the longitudinal water guide channel has an M-shaped structure, and the bottom sides of the longitudinal water guide channel are provided with pressure edges, which are connected to pressure plate bolt assemblies that fix the longitudinal water guide channel to the crossbeam.

[0014] Preferably, the sloping roof has an eaves platform on its longitudinal lower side, the eaves platform has a raised platform at its edge, a column is installed on the eaves platform, the upper end of the column is connected to the crossbeam through a hinge, and the middle part of the column is connected to the longitudinal lower end of the sloping beam through a hinge; and / or, the sloping beam is installed on the sloping roof through a hook assembly.

[0015] In addition, a rooftop photovoltaic power station is provided, including the aforementioned water tank raised installation structure.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. The water trough elevation installation structure includes a sloping beam, a horizontal beam, and elevation connecting components. The sloping beam extends longitudinally along the sloping roof. The photovoltaic modules and the longitudinal water channel are fixed on the horizontal beam. The lower end of the elevation connecting component is connected to the sloping beam, and the upper end is connected to the horizontal beam. In this way, the horizontal beam can be raised by setting the elevation connecting components above the sloping beam. Compared with the existing technology, by adding multiple elevation connecting components between the conventional sloping beam and the horizontal beam, the installation height of the photovoltaic modules and the water trough is raised, which can effectively solve the problem of needing to raise the platform when installing water troughs on sloping roof photovoltaic roofs.

[0018] Furthermore, since there is no need to install double inclined beams, the crossbeam is directly supported by the raised connecting component, avoiding the cost of adding an additional inclined beam. The raised connecting component significantly reduces costs compared to adding an inclined beam or using other raised support structures. Simultaneously, the elimination of the need for an additional inclined beam effectively reduces the component height, decreasing the exposed area of ​​the support structure and extending its service life.

[0019] 2. The lifting connection component includes a first connector. The upper end of the first connector is provided with a crossbeam positioning groove. The crossbeam is positioned in the crossbeam positioning groove. Since the crossbeam needs to be connected to the first connectors of multiple lifting connection components in the transverse direction, positioning the crossbeam in the crossbeam positioning groove can facilitate the positioning of the crossbeam. Then, the crossbeam can be fixed to the bottom wall of the crossbeam positioning groove using fastening bolts.

[0020] 3. The second connector and the inclined beam positioning groove extend along the extension direction of the inclined beam, and fastening bolts are provided on both sides of the longitudinal direction of the first connector and between the first connector and the inclined beam. This facilitates the positioning of the second connector on the inclined beam. Then, the fastening bolts are used to fix the second connector to the inclined beam. This not only facilitates fixing, but also makes the fixation more reliable with double bolts.

[0021] 4. Since both the first and second connecting parts are made of structural steel, they can be customized and mass-produced in the factory, avoiding on-site cutting, ensuring on-site construction efficiency. Moreover, the high strength of the structural steel ensures the reliability of the connection and reduces costs. It also has the advantages of rust prevention and long service life.

[0022] 5. The raised connecting components are arranged in multiple intervals along the longitudinal extension direction of the inclined beam, and the height of the multiple raised connecting components gradually increases from the upper longitudinal side to the lower longitudinal side, thereby raising the lower longitudinal end of the inclined beam to be higher than or roughly level with the eaves platform, so as to avoid the eaves platform from casting shadows on the lower longitudinal photovoltaic modules and affecting the power generation efficiency.

[0023] 6. The bottom sides of the longitudinal water guide channel are equipped with pressure edges, which are connected to pressure plate assemblies that fix the longitudinal water guide channel to the mounting beam. Since the pressure plate assembly is a relatively mature structure, it can reliably fix the longitudinal water guide channel and facilitate quick fixation.

[0024] 7. As a type of building structure, the sloping roof has an eaves platform on its longitudinal lower side, and the edge of the eaves platform has a raised platform. For this type of building, columns are installed on the eaves platform. The upper end of the column is connected to the crossbeam via a hinge, and the middle part of the column is connected to the longitudinal lower end of the sloping beam via a hinge. This facilitates the connection between the longitudinal lower end of the sloping beam and the crossbeam and the column, and ensures that the longitudinal lower end of the sloping beam and the longitudinal lower end of the drainage channel are reliably fixed.

[0040] 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.

[0041] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0042] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "horizontal," and "vertical" that indicate orientation or positional relationship are based solely on the orientation or positional relationship 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.

[0043] 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.

[0044] 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.

[0045] In existing technologies, dual-slope roof photovoltaic power stations have photovoltaic modules installed on both sides of the sloping roof, and these modules are generally arranged in a rectangular array. For example... Figure 10 As shown, a longitudinal water channel 1 is provided between two horizontally adjacent photovoltaic modules 4 for drainage.

[0046] Reference Figure 9 As shown, in this embodiment, the longitudinal water guide channel 1 adopts an M-shaped water channel, that is, the cross-section is M-shaped, with outer walls 11 on both sides of its transverse direction and a groove 12 in the middle. In addition, as a typical structure, pressure edges 13 are provided on both sides of the bottom, and the edges of the pressure edges 13 are provided with upward folded edges 14.

[0047] like Figure 1In the building type shown, photovoltaic modules 4 are installed on one or both sides of the sloping roof 71. The sloping roof has an eaves platform 72 on its longitudinal lower side, and an elevated platform 73 is provided at the edge of the eaves platform. Therefore, the photovoltaic modules and the longitudinal drainage channel need to be raised for installation.

[0048] To address the issue of needing to raise the water trough due to the platform at the eaves, such as Figures 1 to 9 As shown, this embodiment provides a raised installation structure for a photovoltaic roof gutter on a sloping roof. The raised installation structure includes a sloping beam 3, a horizontal beam 5, and raised connecting components 2. The sloping beam 3 extends longitudinally along the sloping roof. The photovoltaic modules 4 and the longitudinal water channel 1 are fixed to the horizontal beam 5. The lower end of the raised connecting component 2 is connected to the sloping beam, and the upper end is connected to the horizontal beam 5. The upper longitudinal end of the sloping beam 3 extends to one side of the roof ridge, and the lower longitudinal end extends above the eaves platform. Multiple raised connecting components 2 are spaced apart along the longitudinal (sloping) extension direction of the sloping beam and have different heights. Specifically, the height of the multiple raised connecting components 2 gradually increases from the upper longitudinal side to the lower longitudinal side, thereby raising the lower longitudinal end of the sloping beam 3 to above or approximately level with the eaves platform. This avoids the eaves platform casting shadows on the lower longitudinal photovoltaic modules, thus affecting power generation efficiency.

[0049] Compared with the prior art, this embodiment adds multiple lifting connection components between the conventional inclined beam and the horizontal beam to raise the installation height of the photovoltaic module and the water tank, which can effectively solve the problem of needing to raise the platform when installing water tanks on a sloping roof photovoltaic roof.

[0050] Since there's no need for double diagonal beams, the crossbeam is directly supported by the raised connecting component, avoiding the cost of adding a diagonal beam. Furthermore, the raised connecting component significantly reduces costs compared to adding a diagonal beam or using other raised support structures. Simultaneously, eliminating the need for an additional diagonal beam effectively lowers the component height, reducing the exposed area of ​​the support structure and extending its service life.

[0051] like Figures 2 to 8As shown, the lifting connection component 2 includes a first connector 21, the upper end of which is provided with a crossbeam positioning groove 211, and the crossbeam 5 is positioned within the crossbeam positioning groove 211. The lifting connection component 2 also includes a second connector 22, the lower end of which is provided with an inclined beam positioning groove 221, and the inclined beam 3 is positioned within the inclined beam positioning groove 221. Fastening bolts 23 are provided between the crossbeam 5 and the bottom wall of the crossbeam positioning groove, and between the inclined beam and the bottom wall of the inclined beam positioning groove. The second connector and the inclined beam positioning groove extend along the inclined beam's extension direction, and fastening bolts 23 are provided on both longitudinal sides of the first connector and between the first connector and the inclined beam. Since the crossbeam needs to be connected to the first connectors of multiple lifting connection components in the transverse direction, positioning the crossbeam within the crossbeam positioning groove facilitates crossbeam positioning, and then the fastening bolts are used to fix the crossbeam to the bottom wall of the crossbeam positioning groove. Position the inclined beam in the inclined beam positioning groove to facilitate the positioning of the second connector on the inclined beam. Then, use fastening bolts to fix the second connector to the inclined beam. This not only makes fixing easier, but also makes the fixation more reliable with double bolts.

[0052] Preferably, both the first connector 21 and the second connector 22 are made of structural steel, such as stainless steel. The first connector has a rectangular portion 212 below the positioning groove of the crossbeam, and the rectangular portion has a rectangular cavity. The first connector 21 and the second connector 22 can be customized and mass-produced in the factory, avoiding on-site cutting, ensuring on-site construction efficiency. Moreover, the structural steel has high strength, ensuring the reliability of the connection, reducing costs, and also has the advantages of rust resistance and long service life.

[0053] like Figures 10 to 12 As shown, for the installation of the longitudinal water guide channel 1, the pressing edge 13 is connected to a pressing plate bolt assembly 6 that fixes the longitudinal water guide channel to the crossbeam 5. The pressing plate bolt assembly is a relatively mature structure, thus it can reliably fix the longitudinal water guide channel. Specifically, the pressing plate bolt assembly 6 includes an upper pressing plate 61, a lower pressing plate, and a pressing plate bolt 62 connecting the upper and lower pressing plates. The upper pressing plate 61 is pressed onto the pressing edge 13, and the lower pressing plate is located below the crossbeam. The pressing plate bolt 62 is a U-bolt. The upper pressing plate 61 includes a pressing part 611 that cooperates with the pressing edge, a bridging part 612 that crosses the upper flange, and a support part 613 that is pressed onto the crossbeam. The bridging part 612 is connected to the pressing plate bolt 62.

[0054] Additionally, a column 8 is installed on the eaves platform. The upper end of the column is connected to the crossbeam via a hinge 81, and the middle part of the column is connected to the lower longitudinal end of the inclined beam via a hinge. The inclined beam is installed on the sloping roof via a hook assembly 9. This facilitates the connection between the lower longitudinal end of the inclined beam and the crossbeam and the column, and ensures that the lower longitudinal end of the inclined beam and the lower longitudinal end of the drainage channel are reliably fixed.

[0055] Furthermore, a waterproof cover plate can be installed above the roof ridge to connect the photovoltaic modules on opposite sides of the sloping roof. This can cover the gaps between the photovoltaic modules on the sloping roof sides, preventing water leakage. In addition, since the waterproof cover plate has guide surfaces on both longitudinal sides that contact the surface of the photovoltaic modules, it not only prevents rainwater from entering the roof ridge but also directs the rainwater to the surface of the photovoltaic modules.

[0056] 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.
