Description

Technical field

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

[0002] Gable roofs are very common in buildings. With the increasing use of gabled photovoltaic panels on sloping roofs, gabled roofing has become a mainstream solution. To meet market demand, major companies are researching waterproofing solutions for sloping roof supports, adding water channels to ensure roof waterproofing. However, these solutions increase the cost of water channels and fail to effectively enhance market competitiveness. Existing technologies also propose replacing sloping beams with M-shaped water channels, reducing the number of supports and construction steps, thereby reducing costs and increasing efficiency.

[0003] When replacing inclined beams with M-shaped gutters, a ridge connector is typically installed above the roof ridge. The connector extends along the ridge, and the upward-sloping ends of the M-shaped gutters on opposite sides of the roof connect to the connector. Due to the roof slope and the unique structure of the M-shaped gutters, connecting the upward-sloping ends of the M-shaped gutters to the ridge connector is difficult, making on-site operation inconvenient and affecting construction progress. [Utility Model Content]

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a sloping roof herringbone slope M-shaped gutter connection structure and a photovoltaic power station, so as to solve the problem that the upward oblique ends of the M-shaped gutter on the sloping roofs on opposite sides of the roof cannot be quickly connected.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] First, an M-shaped gutter connection structure for a sloping roof with a gable slope is provided, photovoltaic modules are laid on the sloping roofs on opposite sides of the roof, and an M-shaped longitudinal water guide groove is provided between two laterally adjacent photovoltaic modules. The M-shaped gutter connection structure includes a gutter connector located above the roof ridge, and the gutter connector has oblique overlapping portions on both longitudinal sides corresponding to the longitudinal upper ends of the longitudinal water guide grooves on the sloping roofs on both sides, the oblique overlapping portions have the same inclination angle as the longitudinal water guide grooves, and the oblique overlapping portions have overlapping edges on both lateral sides corresponding to the outer side walls on both lateral sides of the longitudinal water guide grooves and connected by fasteners.

[0007] Preferably, the cross section of the oblique overlapping portion is an M-shaped structure, and is overlapped on the outer side of the longitudinal upper end of the longitudinal water guide groove.

[0008] Preferably, the fasteners are fastening bolts, and the overlapping edges on both sides of the oblique overlapping portion are connected to the outer side walls on both sides of the longitudinal water guide groove via fastening bolts.

[0009] Preferably, the water trough connector is a sheet metal part; and / or the oblique overlapping portion is fixed to the overlapping portion of the longitudinal upper end of the longitudinal water guide trough by gluing.

[0010] Preferably, a waterproof cover plate is provided above the roof ridge, connecting the photovoltaic components on the sloping roofs on opposite sides of the roof.

[0011] Preferably, pressure edges are provided on both sides of the bottom of the longitudinal water guide trough, and the pressure edges are connected to a pressure plate assembly that fixes the longitudinal water guide trough to the mounting beam.

[0012] Preferably, the pressure plate assembly includes an upper pressure plate, a lower pressure plate and pressure plate bolts connecting the upper pressure plate and the lower pressure plate, the upper pressure plate is pressed on the pressure edge, and the lower pressure plate is arranged below the mounting beam.

[0013] Preferably, the pressure plate bolt is a U-shaped bolt.

[0014] Preferably, the edge of the pressing edge is provided with an upper flange, and the upper pressing plate includes a pressing portion cooperating with the pressing edge, a bridge portion spanning the upper flange, and a supporting portion pressed on the mounting beam, wherein the bridge portion is connected to the pressing plate bolts.

[0015] In addition, a photovoltaic power station is provided, comprising the M-shaped water tank connection structure.

[0016] The utility model adopts the above technical solution, which has the following beneficial effects:

[0017] 1. A gutter connector is provided above the roof ridge, and each gutter connector is separately connected to the longitudinal upper ends of two corresponding longitudinal water guide grooves on the sloping roofs on both sides. In this way, the gutter connector can be provided with a structure adapted to the shape of the M-shaped gutter, wherein the opposite sides of the gutter connector are provided with oblique overlapping portions corresponding to the longitudinal upper ends of the longitudinal water guide grooves on the sloping roofs on both sides. Since the oblique overlapping portions and the longitudinal water guide grooves have the same inclination angle, the oblique overlapping portions can be overlapped with the longitudinal upper ends of the longitudinal water guide grooves after overlapping and matching. The overlapping edges of the oblique overlapping portions can be fitted with the outer side walls of the longitudinal water guide grooves, and then quickly connected by fasteners, so that the longitudinal water guide grooves on both sides and the gutter connector form a whole, thereby solving the problem that the oblique upper ends of the M-shaped gutter on the sloping roofs on opposite sides of the roof cannot be quickly connected.

[0018] 2. The cross-section of the oblique overlap portion is designed to be an M-shaped structure, which is the same as the cross-sectional structure of an M-shaped gutter. Therefore, it can be overlapped on the outer side of the longitudinal upper end of the longitudinal water guide groove, especially the overlapping edges on both sides can fit with the outer side walls on both sides of the longitudinal water guide groove, which facilitates the installation of the gutter connector and quick connection through fasteners.

[0019] 3. The fasteners use fastening bolts, which are not only convenient but also reliable.

[0020] 4. Since the sink connectors are made of sheet metal, preferably stainless steel or aluminum alloy, they can be customized and mass-produced in the factory, eliminating on-site cutting and ensuring efficient construction. The high structural strength of sheet metal ensures the reliability of the connection, reduces costs, and is corrosion-resistant and has a long service life. Furthermore, the oblique overlap and the longitudinal upper end of the longitudinal water channel are glued together to ensure a secure and leak-proof fit.

[0021] 5. A waterproof cover plate is provided above the roof ridge, connecting the photovoltaic modules on the sloping roofs on both sides of the roof. It can block the gaps between the photovoltaic modules on the sloping roofs on both sides to prevent water leakage.

[0022] 6. There are pressure edges on both sides of the bottom of the longitudinal water guide trough, and the pressure edges are connected to the pressure plate assembly that fixes the longitudinal water guide trough to the mounting beam. The pressure plate assembly is a relatively mature structure at present, so the longitudinal water guide trough can be reliably fixed.

[0023] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0039] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0040] In the prior art, photovoltaic power stations installed on gable roofs have photovoltaic modules laid on the opposite sides of the roof, and the photovoltaic modules are generally arranged in a rectangular array. Figure 7 As shown, a longitudinal water channel 1 is provided between two laterally adjacent (rows) photovoltaic modules 4 for drainage.

[0041] Reference Figures 1 to 7 As shown, in this embodiment, the longitudinal water guide trough 1 adopts an M-shaped water guide trough, that is, the cross section is M-shaped, and the outer side walls 11 are provided on the horizontal sides, and a groove 12 is provided in the middle. In addition, as one of the typical structures, the bottom sides are provided with pressure edges 13, and the edges of the pressure edges 13 are provided with upwardly folded upper flanges 14. In response to the scheme for installing the M-shaped water guide trough, this embodiment provides a sloping roof herringbone slope M-shaped water guide trough connection structure, the M-shaped water guide trough connection structure includes a water guide connector 2 located above the roof ridge, the water guide connector 2 is generally inverted V-shaped (when viewed from the horizontal direction), and the water guide connector 2 is provided with oblique overlapping portions 21 on opposite longitudinal sides corresponding to the longitudinal upper ends of the longitudinal water guide troughs 1 on the sloping roof on both sides. The oblique overlapping portions 21 have the same inclination angle as the longitudinal water guide trough 1, and the oblique overlapping portions 21 are provided with overlapping edges 22 on the horizontal sides corresponding to the outer side walls 11 of the longitudinal water guide trough and connected by fasteners.

[0042] A gutter connector is provided above the roof ridge, and each gutter connector is separately connected to the longitudinal upper ends of the two corresponding longitudinal water guide grooves on the sloping roofs on both sides. In this way, the gutter connector can be provided with a structure adapted to the shape of the M-shaped gutter, wherein the opposite sides of the gutter connector are provided with oblique overlapping portions corresponding to the longitudinal upper ends of the longitudinal water guide grooves on the sloping roofs on both sides. Since the oblique overlapping portions and the longitudinal water guide grooves have the same inclination angle, the oblique overlapping portions can be overlapped with the longitudinal upper ends of the longitudinal water guide grooves after overlapping and matching. The overlapping edges of the oblique overlapping portions can be fitted with the outer side walls of the longitudinal water guide grooves, and then quickly connected by fasteners, so that the longitudinal water guide grooves on both sides and the gutter connector form a whole, thereby solving the problem that the oblique upper ends of the M-shaped gutters on the sloping roofs on opposite sides of the roof cannot be quickly connected.

[0043] As one configuration of the sink connector, the oblique overlapping portion 21 has an M-shaped cross-section and overlaps the outer longitudinal upper end of the longitudinal water channel. Thus, the central recessed portion of the sink connector mates with the groove 12, while the overlapping edges 22 on either side can mate with the outer transverse walls 11 of the longitudinal water channel 1. This facilitates installation of the sink connector and allows for quick connection using fasteners.

[0044] Preferably, the fastener is a fastening bolt 3, and the overlapping edges on both sides of the oblique overlapping portion are connected to the outer side walls of the longitudinal water guide groove via fastening bolts 3. It is not only convenient to fix, but also reliable. And multiple fastening bolts can be set along the overlapping direction. Figure 3 and Figure 4 As shown, in this embodiment, three bolts are provided on one side of each oblique overlapping portion 21, and there are a total of six bolts on both sides, and each water tank connector requires 12 bolts.

[0045] In order to facilitate the cooperation with the fastening bolts, the overlapping edges 22 on both sides of the oblique overlapping part and the outer walls 11 on both sides of the longitudinal water guide groove are provided with waist-shaped holes that cooperate with the bolts, namely, the first waist-shaped hole 23 is set on the outer wall of the longitudinal water guide groove, and the second waist-shaped hole 15 is set on the overlapping edge.

[0046] In addition, the oblique overlapping portion 21 and the longitudinal upper end overlapping portion of the longitudinal water guide groove 1 are glued and sealed to ensure reliable fixation and no water leakage.

[0047] Preferably, the sink connector 1 is a sheet metal part. Stainless steel or aluminum alloy is preferred, which can be customized and mass-produced in the factory, avoiding on-site cutting and ensuring on-site construction efficiency. The sheet metal part has high structural strength, ensuring the reliability of the connection. The use of sheet metal parts can reduce costs and has the advantages of being rust-resistant and having a long service life.

[0048] It is understandable that the specific shape of the oblique overlapping portion 21 can be changed, such as Figure 5 As shown, as another structure of the sink connector, the cross section of the oblique overlapping portion 21 can be transformed into a U-shaped structure.

[0049] Furthermore, a waterproof cover plate can be installed above the roof ridge, connecting to the photovoltaic modules on opposite sides of the roof. This can block the gaps between the photovoltaic modules on the two sloping roofs, preventing water leakage. Furthermore, since the waterproof cover plate has guide surfaces on both longitudinal sides that connect to the surfaces of the photovoltaic modules, it not only prevents rainwater from entering the roof ridge but also directs it toward the surface of the photovoltaic modules.

[0050] like Figure 7 As shown, in order to install the longitudinal water channel 1, the pressure edge 13 is connected to the pressure plate assembly 6 that fixes the longitudinal water channel to the mounting beam 5. The pressure plate assembly is a relatively mature structure at present, so the longitudinal water channel can be reliably fixed. Specifically, as Figure 8 and Figure 9 As shown, the pressure plate assembly 6 includes an upper pressure plate 61, a lower pressure plate and pressure plate bolts 62 connecting the upper pressure plate and the lower pressure plate, wherein the upper pressure plate 61 is pressed on the pressure edge 13, and the lower pressure plate is arranged below the mounting beam.

[0051] Preferably, the pressure plate bolt 62 is a U-shaped bolt. The upper pressure plate 61 includes a pressing portion 611 that cooperates with the pressure edge, a bridge portion 612 that spans the upper flange, and a support portion 613 that is pressed onto the mounting beam, wherein the bridge portion 612 is connected to the pressure plate bolt 62.

[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.
