Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support structure technology, and in particular to a novel photovoltaic support system for color steel tile roofs where both the component angle and azimuth angle are adjustable. Background Technology

[0002] Photovoltaic projects using corrugated steel roof tiles have been developing for over a decade and have now entered the stage of large-scale application. However, photovoltaic modules in early power plants generally suffer from significant power degradation. In addition, these projects often use flat installation methods without considering azimuth angle; dust easily accumulates on the module surface, severely restricting the system's power generation efficiency, resulting in a year-on-year decline in actual power generation, which is generally lower than the initial expectations. Currently, only a few photovoltaic projects on corrugated steel roofs have attempted to use tilted photovoltaic support systems. These typically use angle steel or expansion sleeves as the rear support structure, which is not only heavy and costly but also suffers from insufficient construction precision, making it difficult to achieve optimal power generation performance. Furthermore, their support structures are complex and expensive, and the azimuth angle of the modules is not optimized. Ultimately, this leads to significant power generation losses in corrugated steel roof photovoltaic systems due to the tilt and azimuth angle configuration of the modules, resulting in a reduction in the overall power generation efficiency of the photovoltaic system. To address the aforementioned issues, there is an urgent need for a photovoltaic support system with adjustable component tilt and azimuth angles. This system would enable comprehensive adjustment of both the tilt and azimuth angles of the photovoltaic panels, effectively alleviating the dust accumulation problem caused by flat installations. Under the premise of ensuring structural safety and economy, it would maximize power generation efficiency and overall project benefits. Utility Model Content

[0003] The purpose of this invention is to provide a novel photovoltaic support system for corrugated steel tile roofs, in which both the tilt angle and azimuth angle of the components are adjustable. By adjusting the tilt angle and azimuth angle, the optimal angle matching between the tilt angle of the photovoltaic panel and the solar altitude angle can be achieved, maintaining high power generation efficiency even in different seasons and times.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A novel photovoltaic support system for corrugated steel tile roofs with adjustable component angles and azimuth angles includes an adjustable column assembly and a inclined beam assembly. The adjustable column assembly includes a corrugated steel tile roof clamp at the bottom and a guide column at the top. Several concentric first arc-shaped holes are opened on the upper side of the corrugated steel tile roof clamp and / or the guide column. Bolts that connect the corrugated steel tile roof clamp and the guide column at different angles are provided in the first arc-shaped holes. The guide column is equipped with an adjustment plate that slides up and down along it. The adjustment plate is equipped with fasteners that fix it at different heights on the guide column. The adjustment plate is also equipped with a corner piece, and a sloping beam assembly is connected to the corner piece. A photovoltaic module is installed above the sloping beam assembly.

[0005] Furthermore, the fastening component includes a fastening screw and a fastening nut, the guide column includes two opposing side plates, the side plates are connected inward to a mounting surface, the adjusting plate abuts against the outside of the side plates and / or the mounting surface, the fastening nut abuts against the inside of the mounting surface, and the fastening screw passes through the gap between the adjusting plate and the two side plates in sequence and is threadedly connected to the fastening nut.

[0006] Furthermore, the inner side of the mounting surface is provided with teeth along its length, and the two sides of the set nut are also provided with meshing anti-slip teeth.

[0007] Furthermore, the adjustment plate has a C-shaped cross-section, with its inner surface abutting against the outer periphery of the guide column.

[0008] Furthermore, a first circular hole and an arc-shaped elongated hole are provided on one side of the corner piece and / or the adjusting plate. The arc-shaped elongated hole is concentric with the first circular hole. Bolts are connected in both the first circular hole and the arc-shaped elongated hole to connect the corner piece at different angles.

[0009] Furthermore, a T-slot is provided on one side of the inclined beam assembly, and a bolt is provided in the T-slot to slide along it, the bolt fixing the inclined beam assembly at different positions of the corner piece.

[0010] Furthermore, the corner piece has an arc-shaped or straight elongated hole on its upper side, and the elongated hole is used to fix the inclined beam assembly.

[0011] Furthermore, the corrugated steel roofing clamp includes a bottom corrugated clamp and an upper clamp top plate; the corrugated clamp is adapted to the corresponding corrugated steel tile type, and the first arc-shaped hole is opened in the clamp top plate.

[0012] Furthermore, it also includes another adjusting column assembly, with the inclined beam assembly connected to the two adjusting column assemblies.

[0013] Furthermore, the first arc-shaped holes in the two adjusting column assemblies are concentrically set about the same axis.

[0014] In summary, this utility model has the following beneficial effects: 1. By taking into account the installation tilt angle of the components, the photovoltaic panels can maximize the reception of direct sunlight in different seasons and at different latitudes, thereby maximizing the amount of solar irradiance received, directly increasing power generation and revenue; 2. A reasonable tilt angle can reduce snow accumulation on the surface of the modules, avoiding sunlight blockage caused by snow accumulation in winter; in addition, a reasonable tilt angle can also reduce the impact of dust accumulation; while increasing power generation, it also reduces the frequency of later maintenance of photovoltaic modules and reduces labor costs. 3. A proper tilt angle also helps photovoltaic modules self-clean. When rainwater or snow falls on photovoltaic modules, the tilt angle can cause this water to flow down quickly, carrying away dust and dirt from the module surface, thus keeping the modules clean and enabling efficient power generation; 4. The coexistence of a reasonable inclination angle and a stable triangular shape, compared with the flat form, increases the structural stability and better ensures the overall stability of the support structure, provided that the roof load is met. 5. Taking into account the module azimuth angle, a due south orientation (0° azimuth angle) allows the photovoltaic panels to receive the most direct sunlight throughout the year. By rotating the support column to adjust the module azimuth angle, keeping it within ±15° of due south, the power generation loss is only about 1%. Therefore, the power generation efficiency is significantly improved, directly leading to an increase in power generation and thus improving economic benefits. 6. Azimuth adjustment can avoid oblique sunlight in the morning or evening as needed, and can also reduce overheating problems caused by prolonged direct sunlight, thereby extending the service life of the equipment.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0018] Example 1: A novel photovoltaic support system for corrugated steel tile roofs, where both the component angle and azimuth angle are adjustable, such as... Figure 1 and Figure 2 As shown, it includes an adjusting column assembly and a sloping beam assembly 6. The adjusting column assembly includes a bottom corrugated steel roof clamp 1 and an upper guide column 2. The corrugated steel roof clamp 1 includes a bottom corrugated clamp 11 and an upper clamp top plate 12. The corrugated clamp 11 and the clamp top plate 12 are integrally connected. The corrugated clamp 11 is adapted to the corresponding corrugated steel tile type and can also be set as a base or other forms. The guide column 2 is provided with an adjustment plate 4 that slides up and down along it. The adjustment plate 4 is provided with a fastener 3 that fixes it at different heights of the guide column 2 (in this embodiment, there are two fasteners 3, one above and one below). The adjustment plate 4 is provided with a corner piece 5, and the corner piece 5 is connected to the inclined beam assembly 6. A photovoltaic module is installed above the inclined beam assembly 6.

[0019] like Figure 1 and Figure 2 As shown, the guide column 2 includes a column base plate 22 and a U-shaped column 21 welded to the column base plate 22. In order to achieve the adjustment of the azimuth angle, a pair of concentric first arc holes are opened on the clamp top plate 12 and the column base plate 22 respectively. When the clamp top plate 12 and the column base plate 22 overlap, the upper and lower pairs of first arc holes also overlap accordingly. The first arc hole is provided with bolts that connect the color steel tile roof clamp 1 and the guide column 2 at different angles, so that the guide column 2 can be rotated and adjusted to a certain angle and then fixed. The center of the first arc hole is preferably the geometric center of the clamp top plate 12. The rotation angle of the guide column 2 is limited to ±15°.

[0020] like Figure 3 and Figure 4 As shown, the fastening member 3 includes a fastening screw 31 and a fastening nut 32. The U-shaped column 21 includes an inner plate and two opposite side plates, which are perpendicular to each other. The side plates are connected to the mounting surface inward (in this embodiment, the U-shaped column 21 is obtained by bending the side plates and inner plate perpendicular to each other twice, and the mounting surface is obtained by further bending the side plates inward). The adjusting plate 4 has a C-shaped cross-section. Its inner side abuts against the outer periphery of the opening side of the U-shaped column 21. The set nut 32 abuts against the inner side of the mounting surface. The set screw 31 passes through the adjusting plate 4 and the gap between the two mounting surfaces in sequence, and is then threaded to the set nut 32. In this embodiment, in order to improve the stability of fastening, the mounting surface includes a toothed edge that is further bent inward (the toothed edge is parallel to the two side plates of the U-shaped column 21). The toothed edge has teeth arranged in an array along its length direction on its inner side. The set nut 32 is square and also has meshing anti-slip teeth on both sides.

[0021] like Figure 2 As shown, the corner piece 5 is L-shaped and includes an integrally connected vertical plate and a vertical mounting plate. A first circular hole and an arc-shaped elongated hole are opened on one side of both the vertical plate and the adjusting plate 4 (when the vertical plate and the adjusting plate 4 overlap, the first circular hole and the arc-shaped elongated hole also overlap accordingly). The arc-shaped elongated hole is concentric with the first circular hole. Bolts are connected in both the first circular hole and the arc-shaped elongated hole to connect the corner piece 5 to the adjusting plate 4 at different angular positions around the first circular hole. The vertical mounting plate on the upper side of the corner piece 5 has a straight elongated hole, and the elongated hole is used to fix the inclined beam assembly 6. The upper and lower sides of the inclined beam assembly 6 are respectively connected to T-slots, and bolts are provided in the T-slots to slide along them. The lower T-slot is used to fix the inclined beam assembly 6 at different positions of the corner piece 5 with bolts, and the upper T-slot is used to connect the photovoltaic module with bolts.

[0022] Example 2: like Figure 5 As shown, this embodiment has a largely the same structure as Embodiment 1, with the main difference being that... To improve stability, another adjusting column assembly is provided. The inclined beam assembly 6 is connected to the corner piece 5 of the two adjusting column assemblies. The two adjusting column assemblies have the same structure and are arranged in parallel. The only difference is that in order to adjust the azimuth angle, the first arc-shaped holes in the two adjusting column assemblies are concentrically arranged about the same axis. The axis position is preferably the midpoint of the two adjusting column assemblies on the horizontal plane, so that the two guide columns 2 can rotate around the axis position, make a certain angle adjustment, and then be fixed. In some embodiments, a fixed-height column assembly can be set separately, discarding the structure of the adjusting plate 4 and the fastener 3, so that the corresponding corner piece 5 is fixed at the same height position, and only one adjusting column assembly is retained for adjusting the height position at one end.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
