Description

[Technical Field]

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

[0002] Currently, many flat-roof photovoltaic (PV) systems use ballast-type mounting brackets. For example, Chinese utility model patent CN 206077322U discloses a novel flat-roof ballast-type angle-adjustable PV bracket system, including several front columns, front pressure blocks, rear columns, battery modules, and rear pressure blocks. The front columns have a rotating shaft at their top, with the front pressure block mounted on the shaft. The rear columns also have a rotating shaft at their top, with the rear pressure block mounted on the shaft. The front end of the battery module is installed inside the front pressure block, and the rear end is installed under the rear pressure block. The front and rear columns are movable and fixed. By moving the position of the rear column, the distance between the front and rear columns can be adjusted to achieve the desired angle for the battery module. However, for cases where the distance between the front and rear columns is fixed, no solution is provided for adjusting the installation angle of the PV module. [Utility Model Content]

[0017] Preferably, the pressing block assembly includes a single-sided pressing block assembly and a double-sided pressing block assembly. The single-sided pressing block assembly is located on the outer side of the horizontal row of photovoltaic modules, and the upper pressing block has a pressing part on one side. The double-sided pressing block assembly is located between two adjacent photovoltaic modules in the horizontal row of photovoltaic modules, and the upper pressing block has pressing parts on both sides.

[0018] Preferably, the upper pressing block of the single-sided pressing block assembly is provided with a limiting side plate on the side opposite to the pressing part. The limiting side plate includes an upper vertical section, a lower vertical section and an oblique connecting section connecting the upper vertical section and the lower vertical section. The lower vertical section abuts against the lateral outer side of the lower pressing block.

[0019] The present invention adopts the above technical solution and has the following beneficial effects:

[0020] 1. In the above technical solution, the photovoltaic module has a first angle and a second angle. The support leg assembly includes a front support leg and a rear support leg arranged longitudinally along the ballast base. The front support leg is supported below the front side of the photovoltaic module and its bottom is hinged to the ballast base. The rear support leg is supported below the rear side of the photovoltaic module and is higher than the front support leg, so that the photovoltaic module forms an angle with the plane. In order to form the first angle and the second angle, the rear support leg includes a base height rod section and a height adjustment rod section. The bottom of the height adjustment rod section is detachably connected to the top of the base height rod section. The first angle and the second angle are the angles between the photovoltaic module and the mounting plane. In the first angle, the base height rod section alone serves as the rear support leg, supporting the rear side of the photovoltaic module. In the second angle, the base height rod section and the height adjustment rod section are combined to form the rear support leg, supporting the rear side of the photovoltaic module. Therefore, the installation angle of the photovoltaic module can be adjusted without adjusting the distance between the front support leg and the rear support leg.

[0021] 2. Since the pressure block assembly fixes the photovoltaic module to the front and rear support legs, the front support leg will rotate adaptively before and after the photovoltaic module's installation angle is adjusted. The installation angle of the pressure block assembly on the rear support leg will also change. Because the photovoltaic module needs to be supported on the top slope of the rear support leg, the angle of the photovoltaic module must be consistent with the top slope of the rear support leg. Therefore, the top surface of the foundation height rod section is provided with a first angle slope, and the top surface of the height adjustment rod section is provided with a second angle slope to ensure that the pressure block assembly always maintains a fit with the top slope of the rear support leg before and after the installation angle is adjusted.

[0022] 3. To facilitate the rapid assembly of the foundation height section and the height adjustment section, the bottom of the height adjustment section is equipped with a node buckle, which engages and fixes with the first mounting slot at the top of the foundation height section. The node buckle includes a first hook and a second hook arranged opposite each other. The mounting slot has a first retaining edge on its front side and a second retaining edge on its rear side, with the first hook and second hook engaging with the first and second retaining edges respectively. The first hook includes an arc-shaped hook at its head and an oblique section connecting to the arc-shaped hook. The second hook includes an L-shaped hook at its head and a support section connecting to the L-shaped hook. During assembly of the foundation height section and the height adjustment section, the height adjustment section rotates around the point where the arc-shaped hook engages with the first hook, causing the second hook to engage with the second retaining edge. The support section of the second hook engages with the top surface of the second retaining edge for limiting, thus adjusting the leg height.

[0023] 4. The ballast base has a longitudinally extending mounting groove. The bottom of the support leg is connected to the mounting groove with pre-installed bolts. The support leg is stored in the mounting groove in the retracted state. Before packaging and transportation, the support leg is stored in the ballast base through pre-assembly, occupying little space and facilitating the packaging and transportation of photovoltaic support components. During on-site installation, the support leg extends outward from the ballast base, and then the photovoltaic module is installed through the clamping assembly. There is no need for additional assembly of the support leg and ballast base, improving the installation efficiency on the construction site.

[0024] 5. The bottom of the outrigger is provided with a through hole, and the transverse side walls of the mounting groove are provided with corresponding bolt holes. The pre-installed bolts pass through the bolt holes and the through holes. During shipment, both the front and rear outriggers are inserted into the mounting grooves of the ballast base. After arriving at the site, the front and rear outriggers are rotated around the pre-installed bolts respectively. After adjusting the installation angle, the pre-installed bolts are tightened.

[0025] 6. The pressing block assembly includes a single-sided pressing block assembly and a double-sided pressing block assembly, and corresponding designs have been implemented. The single-sided pressing block assembly is located on the outer side of the horizontal row of photovoltaic modules, and the upper pressing block has a pressing part on one side. The double-sided pressing block assembly is located between two adjacent photovoltaic modules in the horizontal row of photovoltaic modules, and the upper pressing block has pressing parts on both sides of the horizontal direction. To ensure reliable pressing of the single-sided pressing block assembly, the upper pressing block of the single-sided pressing block assembly has a limiting side plate on the side opposite to the pressing part. The limiting side plate includes an upper vertical section, a lower vertical section, and an oblique connecting section connecting the upper vertical section and the lower vertical section. The lower vertical section abuts against the outer side of the lower pressing block to ensure that the pressing part is pressed horizontally onto the A surface of the photovoltaic module frame.

[0048] Reference Figures 1 to 14 As shown, this embodiment provides a planar photovoltaic power station, including a photovoltaic module array formed by arranging multiple photovoltaic modules 4 in a rectangular array, and a photovoltaic support for mounting the photovoltaic modules. The photovoltaic support includes:

[0049] Ballast support assembly 1, with at least two rows of ballast support assemblies 1 arranged side by side in the transverse direction, wherein each two rows of ballast support assemblies support one row of photovoltaic modules, the ballast support assembly 1 includes a ballast base 11 and a load component 12 loaded on the ballast base;

[0050] The support leg assembly 2 includes at least two support legs arranged longitudinally along the ballast base 11. The support legs are pre-assembled with the ballast base 11, and the support legs have a retracted state in which they are housed in the ballast base and a supported state in which they extend outward from the ballast base and support the photovoltaic module.

[0051] The clamping assembly 3 is used to fix the photovoltaic module 4 to the support leg.

[0052] For the aforementioned photovoltaic (PV) support system, since the ballast support assembly is placed directly on the flat surface and stable installation is achieved through the counterweight of the load-bearing components, no fasteners are required. The most important components of the PV support system are the ballast support assembly and the leg assembly. In this embodiment, the legs are pre-assembled with the ballast base before packaging and transportation, minimizing space usage and facilitating packaging and transportation of the PV support components. During on-site installation, the legs extend outward from the ballast base, and the PV modules are then installed using the clamping assembly. No additional assembly of the legs and ballast base is required, improving on-site installation efficiency.

[0053] In some embodiments, the ballast base 11 is provided with a longitudinally extending mounting groove 111, and the bottom of the support leg is connected to the mounting groove by a pre-installed bolt 14. The support leg is stored in the mounting groove in the retracted state.

[0054] The load-bearing components can be precast cement blocks. The precast cement blocks are rectangular in shape and their width is smaller than the width of the mounting groove. They can be directly installed into the mounting groove, specifically by stacking multiple layers inside the mounting groove. Of course, most of the cement blocks will be higher than the mounting groove, but lower than the bottom surface of the photovoltaic module at the location.

[0055] Specifically, the bottom of the support leg is provided with a through hole, and the two transverse side walls of the mounting groove are provided with bolt holes 114, and the pre-installed bolts 14 pass through the bolt holes and the through holes.

[0056] In some embodiments, the pre-installed bolt 14 includes a screw 141 and a square nut 142 connected to the screw. A longitudinal groove 112 is provided on one lateral side of the ballast base 11, and the square nut 142 is disposed within the longitudinal groove. During shipment, both the front and rear outriggers are inserted into the mounting grooves of the ballast base. Upon arrival at the site, the front and rear outriggers are rotated around the pre-installed bolt to adjust the installation angle, and then the pre-installed bolt is tightened. Since the square nut is inserted into the longitudinal groove and will not rotate, the pre-installed bolt can be tightened conveniently. Furthermore, the screw 141 is preferably an internal hexagonal screw for easy tightening of the pre-installed bolt. Additionally, on the other lateral side of the ballast base 11, i.e., the side opposite the longitudinal groove 112, an outwardly extending extension surface 113 is provided at the bottom to improve the structural strength of the ballast base and increase its support area.

[0057] For roofs with a long longitudinal length, multiple rows of photovoltaic modules are installed. Correspondingly, each row of ballast support components includes at least two ballast bases 11 spliced ​​along the longitudinal direction. A connecting fastener 13 is provided between two adjacent ballast bases 11, and the connecting fastener 13 is fastened to the ballast base 11. No fasteners are required for fixation, which facilitates on-site installation.

[0058] Specifically, the connecting fastener 13 includes an elastically deformable part 131 that snaps into the mounting groove and a fastening groove 132 that engages with the top of the side wall of the mounting groove. The elastically deformable part 131 has an inverted isosceles trapezoidal structure with its upper base at the bottom and a gap between it and the bottom wall of the mounting groove. The fastening groove 132 has a side limiting part 1321, an upper limiting part 1322, and a V-shaped part 1323. The side limiting part 1321 engages with the inner side of the top of the side wall of the mounting groove, and the inverted isosceles trapezoidal structure of the elastically deformable part 131 deforms to ensure a tight fit between the side limiting part 1321 and the inner side of the side wall of the mounting groove. The upper limiting part 1322 engages with the top of the side wall of the mounting groove, and the V-shaped part 1323 connects to the upper limiting part 1322. During installation, the elastic deformation part 131 is inserted into the mounting groove of the adjacent ballast base through its own elasticity. When the pre-installed bolts are finally tightened, since the connecting fastener 13 and the pre-installed bolts 14 are close to each other, a force will be generated on the connecting fastener, which will further increase its fixing ability.

[0059] Specifically, the support leg assembly includes a rear support leg 21 supporting the lower rear side of the photovoltaic module and a front support leg 22 supporting the lower front side of the photovoltaic module, with the rear support leg being higher than the front support leg. This arrangement causes the photovoltaic module to be lower in the front and higher in the back, creating an angle between the photovoltaic module and the plane, forming a sloping surface facing the direction of sunlight. Because the bottom surface of the photovoltaic module does not need to be too high from the mounting plane, and the photovoltaic module has a standard area, only the front and rear support legs are needed for each photovoltaic module; no intermediate support legs are required.

[0060] The rear support leg 21 and the front support leg 22 are provided with mounting slots at their tops, and the pressure block assembly 3 is provided with mounting buckles that cooperate with the mounting slots. The mounting slot is a C-shaped slot with locking edges on opposite sides of its opening, namely the first locking edge on the front side and the second locking edge on the rear side of the opening.

[0061] like Figure 6As shown, the rear support leg 21 is a hollow rectangular component with a hollow cavity extending through both sides. Connecting ribs connect the front and rear cavity walls, and a second mounting slot 212 is provided at the top. A second hollow hinge post 211 is provided on the front bottom side, with a through hole at its center. Pre-installed bolts pass through this through hole. The second hinge post is located on the front bottom side of the rear support leg, forming an arc-shaped transition surface 2111. The rear support leg has a bottom plane 215 on the rear side of the second hinge post, where the arc-shaped transition surface facilitates forward rotation of the rear support leg and its retraction into the mounting slot.

[0062] like Figure 7 As shown, the front support leg is also a hollow rectangular component with a hollow cavity extending through both sides laterally. Connecting ribs connect the front and rear cavity walls. A first mounting slot 221 is provided at the top, which is also a C-shaped slot. A first and second retaining edges are provided on opposite sides of the opening, extending horizontally outwards. Therefore, the front and rear side walls of the first mounting slot 221 are T-shaped to increase the support area with the photovoltaic module frame. Additionally, a first hollow hinge post 223 is provided at the bottom of the front support leg, with a connecting plate 222 between the first mounting slot 221 and the first hollow hinge post 223. A large gap exists between the first hollow hinge post 223 and the mounting slot to facilitate rotation of the front support leg.

[0063] In this embodiment, a set of bolt holes 114 are provided on the transverse side walls of the mounting groove corresponding to the installation position of the front outrigger, and multiple sets of bolt holes 114 are provided on the transverse side walls of the mounting groove corresponding to the installation position of the rear outrigger. In this way, the rear outrigger can be adjusted to the front and rear installation positions of the mounting groove within a certain range, and only the corresponding bolt holes need to be selected.

[0064] To facilitate adjustment of the photovoltaic module's installation angle, the height of the rear support legs can be adjusted. For example... Figure 8 and Figure 9As shown, the rear support leg 21 includes a base height rod section 213 and a height adjustment rod section 214. The bottom of the height adjustment rod section 214 is detachably connected to the top of the base height rod section. The photovoltaic module has a first angle and a second angle, which are the angles between the photovoltaic module and the mounting plane. At the first angle, the base height rod section alone serves as the rear support leg, supporting the lower rear side of the photovoltaic module. At the second angle, the base height rod section and the height adjustment rod section are combined to form the rear support leg, supporting the lower rear side of the photovoltaic module. Correspondingly, the top surface of the base height rod section has a first-angle slope, and the top surface of the height adjustment rod section has a second-angle slope. Because the photovoltaic module needs to be supported on the top slope of the rear support leg, the angle of the photovoltaic module must be consistent with the top slope of the rear support leg. Therefore, at the first angle, the base height rod section alone serves as the rear support leg, and at the second angle, the base height rod section and the height adjustment rod section are combined to form the rear support leg. Correspondingly, the top surface of the base height rod section has a first-angle slope, and the top surface of the height adjustment rod section has a second-angle slope.

[0065] Furthermore, to facilitate the rapid assembly of the base height rod section 213 and the height adjustment rod section 214, a node buckle is provided at the bottom of the height adjustment rod section. This node buckle engages and is fixed to the first mounting slot 221 at the top of the base height rod section. Specifically, the node buckle includes a first hook 2141 and a second hook 2142 arranged opposite to each other. The first hook and the second hook engage with the first and second locking edges on opposite sides of the opening of the first mounting slot 221. The first hook includes an arc-shaped hook 21411 at its head end and an oblique section 21412 connected to the arc-shaped hook. The second hook includes an L-shaped hook 21421 at its head end and a support section 21422 connected to the L-shaped hook.

[0066] Because the first and second locking edges are angled as a whole, with the first locking edge located on the downward angled side and the second locking edge located on the upward angled side, when the foundation height rod section 213 and the height adjustment rod section 214 are assembled, the height adjustment rod section 214 rotates around the point where the arc hook engages with the first locking hook, causing the second locking hook to engage with the second locking edge. The support section of the second locking hook engages with the top surface of the second locking edge for limiting, thus adjusting the height of the support leg. Additionally, the front support leg can be adjusted by using pre-installed bolts to adjust the angle of the photovoltaic module.

[0067] like Figure 13 and Figure 14As shown, the pressure block assembly includes a lower pressure block, an upper pressure block, and pressure block bolts. The bottom of the lower pressure block is provided with the mounting buckle, and the upper pressure block is provided with a pressing part that presses against the frame of the photovoltaic module. The pressure block bolts fix the upper and lower pressure blocks. The pressure block assembly can be divided into a single-sided pressure block assembly 31 and a double-sided pressure block assembly 32. The single-sided pressure block assembly 31 is located on the outer side of the horizontal row of photovoltaic modules and is connected to the photovoltaic module on only one side. Therefore, the upper pressure block is provided with a pressing part 3121 on one side. The double-sided pressure block assembly is located between two adjacent photovoltaic modules in the horizontal row of photovoltaic modules and is connected to the photovoltaic module on both sides. Therefore, the upper pressure block is provided with pressing parts on both horizontal sides.

[0068] like Figure 13 As shown, taking a single-sided pressing block assembly as an example, the single-sided pressing block assembly 31 includes a lower pressing block 311, an upper pressing block 312, and a pressing block bolt 313. The upper pressing block has a mounting part 3122 with an opening. The lower pressing block has a threaded hole. The pressing block bolt passes through the opening on the upper pressing block from top to bottom and connects with the threaded hole on the lower pressing block. The bottom of the lower pressing block has the aforementioned mounting buckle 3111. The mounting buckle has double-sided hooks, and its hook structure is similar to the second hook structure mentioned above. The upper pressing block of the single-sided pressing block assembly has a limiting side plate 3123 on the side opposite to the pressing part. The limiting side plate includes an upper vertical section 31231, a lower vertical section 31233, and an oblique connecting section 31232 connecting the upper vertical section and the lower vertical section. The lower vertical section abuts against the lateral outer side of the lower pressing block to ensure that the pressing part is pressed into the photovoltaic module frame A surface in a horizontal posture. In addition, single-sided pressure block modules also require the installation of height adjustment plates to accommodate different photovoltaic module installations. The structure of double-sided pressure block modules 32 is basically the same as that of single-sided pressure block modules, but the upper pressure block has pressing parts on both opposite sides, and the lower pressure block does not have a limiting side plate.

[0069] It is understandable that the aforementioned ballast base, legs, and pressure blocks can all be made of profiles, such as steel sections.
