Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation, in particular to a profile support bracket for photovoltaic modules. Background Art

[0002] Photovoltaic power generation, as an important renewable energy power generation technology, has achieved rapid development. The development of domestic household photovoltaics has advanced by leaps and bounds and already occupies a large proportion of the installed capacity of clean energy in the country. Photovoltaic power generation is a process of converting light energy into electrical energy using solar energy. A large number of solar panels (also known as photovoltaic panels or solar panels) are usually installed in the photovoltaic area to collect sunlight and convert it into electrical energy. These solar panels are usually installed in large open areas such as grasslands, wildernesses, rooftops, and solar power plants. The development of the photovoltaic area can promote the utilization of renewable energy, reduce dependence on traditional energy, and has positive significance for environmental protection.

[0003] For the installation of photovoltaic panels, it is usually necessary to use a bracket to erect the photovoltaic panels for photovoltaic power generation, and the bracket is usually built from components with different structures, and the components cannot be used interchangeably. Summary of the Utility Model

[0004] An object of the utility model is to provide a profile support bracket with few component types, simple structure, and easy installation.

[0005] Another object of the utility model is to improve the stability of the bracket to provide stable support for the photovoltaic module.

[0006] In particular, the utility model provides a profile support bracket for a photovoltaic module, which is characterized by comprising:

[0007] A plurality of profile components, which are arranged between the support surface and the photovoltaic module to be supported and are arranged at intervals along the transverse direction of the photovoltaic module; each profile component includes a plurality of angle aluminum materials, and the angle aluminum material includes a first profile plate and a second profile plate that are perpendicular to each other, thereby forming an L-shaped cross-section, and the plurality of angle aluminum materials of each profile component include:

[0008] A bottom beam aluminum material, the first profile plate of which is used to be fixed to the support surface, and the second profile plate thereof is arranged upward;

[0009] An inclined beam aluminum material, the first end of the first profile plate of which is connected to the second profile plate of the bottom beam aluminum material, and the second profile plate thereof is used to support the photovoltaic module;

[0010] A column aluminum material, which is connected between the second end of the first profile plate of the inclined beam aluminum material and the second profile plate of the bottom beam aluminum material, so that the inclined beam aluminum material is inclined along the longitudinal direction of the photovoltaic module, so that the photovoltaic module reaches a set light-receiving angle.

[0011] Furthermore, the profile support bracket of the photovoltaic module further includes:

[0012] A plurality of cross beams are erected on the second profile plates of the inclined beam aluminum materials of the plurality of profile components along the transverse direction of the photovoltaic module, and are respectively connected to the second profile plates of the inclined beam aluminum materials at positions close to both ends of the inclined beam aluminum materials;

[0013] And the plurality of cross beams are connected to the backlight surface of the photovoltaic module to support the photovoltaic module to be inclined.

[0014] Furthermore, the profile support bracket of the photovoltaic module further includes:

[0015] A pressure stopper, including a first straight plate and a second straight plate;

[0016] The first straight plate is attached to the second profile plate of the inclined beam aluminum material, and the second straight plate extends vertically along one end of the first straight plate close to the cross beam, and is used to fixedly connect the cross beam and the second profile plate of the inclined beam aluminum material.

[0017] Furthermore, the cross beam has an open cavity on the side facing the pressure stopper;

[0018] The pressure stopper further includes:

[0019] A pressure plate extends from the first straight plate into the cavity through the opening and abuts against the bottom of the cavity, thereby pressing the cross beam on the second profile plate of the inclined beam aluminum material.

[0020] Furthermore, the side of the cross beam in contact with the backlight surface of the photovoltaic module has a notch, so as to provide support for the photovoltaic module through the partial beam bodies on both sides of the notch along the extending direction of the cross beam.

[0021] Furthermore, the profile support bracket of the photovoltaic module further includes:

[0022] A back-pull aluminum material, which is also an angle-shaped aluminum material. The first profile plates of the back-pull aluminum material are respectively connected to the first profile plates of the column aluminum materials of two adjacent profile components to enhance the stability of the bracket.

[0023] Furthermore, back-pull aluminum materials are provided for the profile components at both ends along the transverse direction of the photovoltaic module, and back-pull aluminum materials are arranged at intervals between the remaining profile components to strengthen and fix the bracket.

[0027] Further, the length of the column aluminum material of the bracket arranged on the north slope is larger than that of the column aluminum material of the bracket arranged on the south slope, so that the photovoltaic modules arranged on the south slope and the north slope can both reach the set light-facing angle.

[0028] For the profile support bracket of a photovoltaic module of the present utility model, since the bottom beam aluminum material, the inclined beam aluminum material and the column aluminum material all use the same angular aluminum material, and the bottom beam aluminum material, the inclined beam aluminum material and the column aluminum material are connected to form a triangular frame, the manufacturing and installation convenience of the bracket is improved. At the same time, the triangular bracket structure can also improve the stability of the bracket.

[0029] Further, by attaching the first straight plate of the pressure stopper to the second profile plate of the inclined beam aluminum material and vertically extending the second straight plate of the pressure stopper along one end of the first straight plate close to the cross beam for fixedly connecting the cross beam and the second profile plate of the inclined beam aluminum material, the stability of the profile support bracket can be improved.

[0038] Figure 1 FIG. 5 is a schematic side view of the profile support bracket 100 of the photovoltaic module 300 according to an embodiment of the present invention. The profile support bracket 100 of the photovoltaic module 300 generally may include a plurality of profile components 110, and the plurality of profile components 110 are used to be arranged between the support surface and the photovoltaic module 300 to be supported, and are arranged at intervals in the transverse direction of the photovoltaic module 300. The support surface may be the ground, the roof 200 or other forms of surfaces that can provide a supporting force for the profile support bracket 100. The photovoltaic module 300 includes a solar panel for performing photovoltaic power generation. The number of the arranged profile components 110 may be determined according to the number of the photovoltaic modules 300 to be actually arranged, and the transverse interval distance between the profile components 110 may be determined according to the weight of the actual photovoltaic module 300. The transverse interval distance between each profile component 110 may be uniform or non-uniform.

[0039] Figure 2 FIG. 9 is a schematic diagram of the angle aluminum 150 in the profile support bracket of the photovoltaic module according to an embodiment of the present invention. Each profile component 110 includes a plurality of angle aluminums 150. The angle aluminum 150 includes a first profile plate 151 and a second profile plate 152 that are perpendicular to each other, thus forming an L-shaped cross section. And the plurality of angle aluminums 150 of each profile component 110 include: a bottom beam aluminum 111, an inclined beam aluminum 112 and a column aluminum 113. Since the bottom beam aluminum 111, the inclined beam aluminum 112 and the column aluminum 113 are all made of the angle aluminum 150, it is beneficial to uniformly process and manufacture the bottom beam aluminum 111, the inclined beam aluminum 112 and the column aluminum 113. And the installation of the profile component 110 is also relatively convenient. After the components in the profile component 110 are damaged, they are also easy to replace.

[0040] Figure 3 FIG. 13 is a schematic diagram of the bottom beam aluminum 111 in the profile support bracket 100 of the photovoltaic module 300 according to an embodiment of the present invention, Figure 3 only the first profile plate 151 of the bottom beam aluminum 111 is shown, and the second profile plate 152 is on the surface perpendicular to the first profile plate 151. Through holes 115 are provided at both ends of the first profile plate 151 close to the bottom beam aluminum 111 for connecting fasteners.

[0041] The present utility model only shows a schematic diagram of the bottom beam aluminum profile 111. The bottom beam aluminum profile 111, the inclined beam aluminum profile 112, and the column aluminum profile 113 are all made of angle aluminum profiles. The differences lie in the length, width, and the position and quantity of the through holes. For example, the inclined beam aluminum profile 112 is a component for directly supporting the photovoltaic module 300 and is located on the backlight side of the entire photovoltaic module 300, so it has a longer length. The column aluminum profile 113 has a shorter length to enable the photovoltaic module 300 to have a set light-receiving angle.

[0042] The bottom beam aluminum profile 111, the inclined beam aluminum profile 112, and the column aluminum profile 113 can be used interchangeably. That is, when assembling profile components 110 of different sizes or assembling profile support brackets 100 with different inclination angles of the inclined beam aluminum profile 112, the bottom beam aluminum profile 111 can be used to replace the inclined beam aluminum profile 112, or the inclined beam aluminum profile 112 can be used to replace the column aluminum profile 113, etc. This improves the utilization efficiency of each component in the profile component 110, and the construction method of the profile component 110 is flexible and variable.

[0043] As Figure 1 shown, the first profile plate 151 of the bottom beam aluminum profile 111 is used to be fixed to the support surface, and the second profile plate 152 of the bottom beam aluminum profile 111 is arranged upward. The first end of the first profile plate 151 of the inclined beam aluminum profile 112 is connected to the second profile plate 152 of the bottom beam aluminum profile 111, and the second profile plate 152 of the inclined beam aluminum profile 112 is used to support the photovoltaic module 300. The column aluminum profile 113 is connected between the second end of the first profile plate 151 of the inclined beam aluminum profile 112 and the second profile plate 152 of the bottom beam aluminum profile 111, so that the inclined beam aluminum profile 112 is inclined along the longitudinal direction of the photovoltaic module 300, so that the photovoltaic module 300 reaches the set light-receiving angle.

[0044] Among them, Figure 1 the arrow in shows the longitudinal direction of the photovoltaic module 300, which can be understood as the length direction of the solar panel in the photovoltaic module 300, and the transverse direction of the photovoltaic module 300 is the direction perpendicular to the longitudinal direction, which can be understood as the width direction of the solar panel in the photovoltaic module 300.

[0045] As Figure 1 shown, in some embodiments of the present utility model, the profile support bracket 100 of the photovoltaic module 300 may further include a plurality of cross beams 120, which are erected on the second profile plates 152 of the inclined beam aluminum profiles 112 of the plurality of profile components 110 along the transverse direction of the photovoltaic module 300 and are respectively connected to the second profile plates 152 of the inclined beam aluminum profiles 112 at positions near both ends of the inclined beam aluminum profiles 112; and the plurality of cross beams 120 are connected to the backlight side of the photovoltaic module 300 to support the photovoltaic module 300 to be inclined. Since the cross beams 120 are erected on the profile components 110, the arrangement quantity of the profile components 110 can be selected according to actual needs.

[0046] Optionally, as Figure 1 shown, two cross beams 120 can be erected on the second profile plate 152 of the inclined beam aluminum material 112. One cross beam 120 is arranged near the connection of the bottom beam aluminum material 111 and the inclined beam aluminum material 112, and the other cross beam 120 is arranged near the connection of the bottom beam aluminum material 111 and the column aluminum material 113.

[0047] In some embodiments of the present utility model, Figure 4 is Figure 1 a schematic partial enlarged view of part A shown in the figure. As shown in the figure, the profile support bracket 100 of the photovoltaic module 300 may further include a pressure stopping member 130. The pressure stopping member 130 includes a first straight plate 131 and a second straight plate 132. The first straight plate 131 is attached to the second profile plate 152 of the inclined beam aluminum material 112, and the second straight plate 132 vertically extends along one end of the first straight plate 131 close to the cross beam 120 for fixedly connecting the cross beam 120 and the second profile plate 152 of the inclined beam aluminum material 112.

[0048] After the first straight plate 131 is attached to the second profile plate 152 of the inclined beam aluminum material 112, it can be fixedly connected by fasteners or by bonding. The second straight plate 132 and the cross beam 120 can be fixedly connected by fasteners or by bonding. The second straight plate 132 can be attached to the side surface of the cross beam 120. In this way, after the pressure stopping member 130 fixes the cross beam 120, the second straight plate 132 of the pressure stopping member 130 can block the movement of the cross beam 120 in the longitudinal direction of the photovoltaic module, thereby preventing the installation position of the photovoltaic module 300 from shifting.

[0049] Continuing to refer to Figure 4 , in some embodiments of the present utility model, the cross beam 120 has a cavity 122 with an opening 121 on the side facing the pressure stopping member 130. The pressure stopping member 130 may further include a pressure stopping plate 133. The pressure stopping plate 133 extends from the first straight plate 131 into the cavity 122 through the opening 121 and abuts against the bottom of the cavity 122, thereby pressing the cross beam 120 against the second profile plate 152 of the inclined beam aluminum material 112. Specifically, the pressure stopping plate 133 can vertically extend from the first straight plate 131 towards the cross beam 120. After extending into the cavity 122, it bends 90° downward and extends to the bottom of the cavity 122, and then bends 90 degrees and extends along the bottom of the cavity 122, so that the pressure stopping plate 133 of the pressure stopping member 130 has a certain contact surface with the bottom of the cavity 122 of the cross beam 120, thereby using the pressure stopping plate 133 of the pressure stopping member 130 to press and fix the cross beam 120.

[0050] Continuing to refer to Figure 4, in some embodiments of the present utility model, one side of the cross beam 120 that contacts the backlight surface of the photovoltaic module 300 has a notch 123, so as to provide support for the photovoltaic module 300 through partial beam bodies on both sides of the notch 123 along the extending direction of the cross beam 120. The contact between the cross beam 120 and the photovoltaic module 300 is a line contact. Compared with the contact between the entire surface of the cross beam 120 and the backlight surface of the photovoltaic module 300, it is less affected by the flatness of the surfaces of the cross beam 120 and the photovoltaic module 300, and the line contact support method is more stable.

[0051] As Figure 1 shown, in some embodiments of the present utility model, the profile support bracket 100 of the photovoltaic module 300 may further include a back-pulling aluminum material 140. The back-pulling aluminum material 140 is selected as an angle aluminum material 150. The back-pulling aluminum material 140 has a first profile plate 151 and a second profile plate 152 that are perpendicular to each other. The first profile plates 151 of the back-pulling aluminum material 140 are respectively connected to the first profile plates 151 of the column aluminum materials 113 of two adjacent profile components 110 to enhance the stability of the bracket 100. Since the profile support bracket 100 includes multiple independent profile components 110, if there are no components connecting and fixing between the respective profile components 110, then the stability of the profile support bracket 100 in the lateral direction of the photovoltaic module 300 is relatively poor.

[0052] From Figure 1 it can be seen the L-shaped cross-section of the back-pulling aluminum material 140. The back-pulling aluminum material 140 is connected to adjacent column aluminum materials 113 in the lateral direction of the photovoltaic module 300.

[0053] Figure 5 is an installation schematic diagram of the back-pulling aluminum material 140 in the profile support bracket 100 of the photovoltaic module 300 according to an embodiment of the present utility model, where the vertical lines represent the column aluminum materials 113, and the oblique lines between two vertical lines represent the back-pulling aluminum material 140. It can be seen from this that the back-pulling aluminum material 140 can be inclinedly arranged. One end of the back-pulling aluminum material 140 is connected to a position near the top of one column aluminum material 113, and the other end of the back-pulling aluminum material 140 is connected to a position near the bottom of another column aluminum material 113. The inclined arrangement of the back-pulling aluminum material 140 can give full play to the supporting role of the back-pulling aluminum material 140.

[0054] In some embodiments of the present utility model, back-pulling aluminum materials 140 are provided on both ends of the profile components 110 in the lateral direction of the photovoltaic module 300, and the back-pulling aluminum materials 140 are arranged at intervals between the remaining profile components 110 to strengthen and fix the bracket 100. As Figure 5 shown, what is shown in the figure are the column aluminum materials 113 of the respective profile components 110. The leftmost and rightmost profile components 110 are both provided with back-pulling aluminum materials 140 to strengthen and fix them.

[0055] Since the leftmost and rightmost profile components 110 are the profile components 110 located on the outermost sides of the profile support bracket 100, and the profile support bracket 100 of the photovoltaic module 300 is usually in an outdoor environment, the bracket 100 often has to face complex and harsh natural environments. The bracket 100 must be able to resist strong winds of a relatively high level to ensure that the photovoltaic module 300 is not damaged. The profile components 110 located on the two side edges are on the outermost sides of the entire bracket 100 and will be subjected to strong impacts from the strong winds. Therefore, it is particularly necessary to use the back-pulling aluminum material 140 to reinforce the two adjacent profile components 110 located on the two side edges.

[0056] Continue to refer to Figure 5 , for the profile components 110 in the profile support bracket 100 except for the profile components 110 at both ends, the back-pulling aluminum material 140 can be arranged at a frequency of one back-pulling aluminum material 140 for every 2 to 4 profile components 110. Preferably, the back-pulling aluminum material 140 can be arranged at a frequency of one back-pulling aluminum material 140 for every 3 profile components 110. At this time, the back-pulling aluminum material 140 has a good strengthening and fixing effect on the profile support bracket 100.

[0057] Continue to refer to Figure 5 , for the leftmost and rightmost profile components 110, when setting the back-pulling aluminum material 140, one end of the back-pulling aluminum material 140 can be connected to the position near the top of the outermost profile component 110, and the other end of the back-pulling aluminum material 140 can be connected to the position near the bottom of the adjacent profile component 110. Since the outermost profile component 110 bears a relatively large external environmental pressure in the harsh natural environment, connecting the back-pulling aluminum material 140 to the position near the top of the outermost profile component 110 can provide a good reinforcement effect on the outermost profile component 110.

[0058] As Figure 1 shown, in some embodiments of the present invention, the profile component 110 may further include a fixture 114. The fixture 114 is fixedly connected to the first profile plate 151 of the bottom beam aluminum material 111 and is clamped on the corrugation 210 of the roof 200 so that the profile component 110 is fixedly connected to the roof 200. The fixture 114 can be connected to the bottom beam aluminum material 111 by bolts or other fasteners. The corrugation 210 can be a color steel tile, and the roof of the color steel tile has strip-shaped protrusions. The fixture 114 can be clamped on the strip-shaped protrusions of the color steel tile roof.

[0059] In some other embodiments of the present invention, the profile component 110 can also be fixedly connected to the roof 200 by means of fastening connectors or bonding.

[0060] In some embodiments of the present utility model, the included angle between the photovoltaic module 300 and the horizontal plane is set between 10 and 20 degrees to improve the power generation efficiency of the photovoltaic module 300. Through practical research, when the included angle between the photovoltaic module 300 and the horizontal plane is adjusted to the above angle range, the power generation efficiency of the photovoltaic module 300 can be significantly improved. Further, the adjustment range of the light-facing angle of the photovoltaic module 300 can be between 13 degrees and 16 degrees, and specifically can be set to 14 degrees, 15 degrees, and 16 degrees. Among them, when the included angle between the photovoltaic module 300 and the horizontal plane is adjusted to 15 degrees, the power generation efficiency reaches the highest. The included angle between the photovoltaic module 300 and the horizontal plane can be adjusted to the above angle value by selecting column aluminum materials 113 of different lengths.

[0061] Figure 6 FIG. 4 is a schematic diagram of the profile support bracket 100 of the photovoltaic module 300 according to an embodiment of the present utility model arranged on the roof 200. In some embodiments of the present utility model, the length of the column aluminum material 113 of the support bracket 100 arranged on the north slope is larger than the length of the column aluminum material 113 of the support bracket 100 arranged on the south slope, so that the photovoltaic modules 300 arranged on the south slope and the north slope can both reach the set light-facing angle.

[0062] The types of the roof 200 are diverse, such as flat roofs, pitched roofs, etc. The roof 200 has different orientations and can be generally divided into roofs 200 with north-south orientations and roofs 200 with east-west orientations. The pitched roof of the roof 200 has two inclined surfaces, including a south slope and a north slope, that is, the house is in an east-west orientation. The south slope is the slope on the south side, and the north slope is the slope on the north side. The arrow in the figure indicates the south direction. The slope on the left is the south slope, and the slope on the north is the north slope.

[0063] As Figure 6 shown, the profile support brackets 100 of multiple photovoltaic modules 300 are arranged at intervals from south to north on the roof 200 in sequence. It should be noted that Figure 6 FIG. 4 shows only a side schematic diagram of the profile support bracket 100 of the photovoltaic module 300. The multiple profile components 110 extend along the lateral direction of the photovoltaic module 300, that is, the orientation of the house. Therefore, only one profile component 110 of the profile support bracket 100 can be seen from the figure. The south slope shadow control line 401 represents the shadow influence area formed by the south-side profile support bracket 100 on the south slope extending northward. The north slope shadow control line 402 represents the shadow influence area formed by the south-side profile support bracket 100 on the north slope extending northward. The ridge shadow control line 403 represents the shadow influence area formed by the profile support bracket 100 near the ridge extending northward.

[0064] In some embodiments of the present utility model, the light-facing angles of the photovoltaic modules 300 can be adjusted to the same angle so that the photovoltaic modules 300 can all generate photovoltaic power with maximum efficiency. Figure 6 On the south slope, four groups of profile support brackets 100 are arranged in sequence from south to north. Since the parameter states adjusted by each group of profile support brackets 100 are the same, the light-facing angles of the photovoltaic modules 300 on each profile support are the same, where the parameter state refers to the length of the column aluminum material 113. Therefore, the spacing distance between two adjacent groups of profile support brackets 100 can be set to be the same, and there is the same south slope shadow control line 401 between two adjacent groups of profile support brackets 100.

[0065] In some embodiments of the present utility model, the spacing distance between the groups of profile support brackets 100 arranged on the north slope is larger than that on the south slope. This is because the north slope slopes down from south to north, and the shadow distance formed after the sun shines on the photovoltaic modules 300 on the north slope is longer. The spacing distance between the groups of profile support brackets 100 needs to be larger so that each group of photovoltaic modules 300 can receive sufficient light and improve the photovoltaic power generation efficiency.

[0066] In some embodiments of the present utility model, for the profile support brackets 100 installed on the north and south slopes, one profile component 110 can be arranged at every other corrugation 210. For the profile support brackets 100 installed on the east and west slopes, the spacing between two adjacent profile components 110 is not greater than 2 meters, and clamps 114 are provided between the bottom beam aluminum material 111 and each of the lower corrugations 210 to ensure that the multiple profile components 110 can provide stable support for the photovoltaic modules 300.

[0067] In some embodiments, different models of solar panels may be included in a group of photovoltaic modules 300. Therefore, the multiple profile components 110 can be unevenly spaced along the transverse direction of the photovoltaic modules 300. According to the specific size and weight of the photovoltaic modules 300, the spacing distance between the profile components 110 is reasonably adjusted so that each profile component 110 can exert the maximum support efficiency and save the number of profile components 110 used.

[0068] In some embodiments of the present utility model, the orientation of the photovoltaic module 300 can be due south. Because in the Northern Hemisphere, the sun is at its highest at noon in the due south direction. The photovoltaic module 300 facing due south can receive sunlight to the greatest extent, thereby achieving the highest power generation efficiency. In other embodiments, the photovoltaic module 300 can face southeast or southwest. The photovoltaic module 300 with this orientation has the highest power generation efficiency in the morning or evening time periods. Or the photovoltaic module 300 faces east or west. In this case, the photovoltaic module 300 has the highest power generation efficiency in the morning or afternoon. However, due to the relatively small total amount of sunlight in the morning or evening, the overall power generation capacity of the photovoltaic module 300 may be slightly lower than that of the photovoltaic module 300 facing south or southeast / southwest.

[0069] In some embodiments of the present utility model, the pressure - stopping members 130 and the cross - beams 120 can be arranged in one - to - one correspondence to stably connect the inclined - beam aluminum profiles 112 and the cross - beams 120. Or one pressure - stopping member 130 can be arranged at every other profile assembly 110 along the transverse direction of the photovoltaic module 300.

[0070] In some embodiments of the present utility model, the column aluminum profile 113 of the profile support bracket 100 can be a component with adjustable length. The length of the column aluminum profile 113 can be directly adjusted, thereby adjusting the light - facing angle of the photovoltaic module 300 supported by the profile support bracket 100. For example, by using other components such as slide rails or cylinders that can achieve telescoping or displacement to adjust the length of the column aluminum profile 113, the photovoltaic module 300 is inclined longitudinally along the photovoltaic module 300, so that the photovoltaic module 300 reaches the set light - facing angle.

[0071] In the present utility model, the bottom - beam aluminum profile 111, the inclined - beam aluminum profile 112, the column aluminum profile 113, and the back - pull aluminum profile 140 are all made of angle aluminum. Using the same material can facilitate unified processing and installation. And angle aluminum has relatively high strength, can withstand large loads and pressures, and has good tensile strength.
