For example, a first feature described later in the specification may be formed over or on a second feature, and may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features are formed between the first and second features, such that the first and second features may not be in direct contact. Further, when a first element is described as being coupled or coupled to a second element, the description includes embodiments in which the first and second elements are directly coupled or coupled to each other, as well as embodiments in which one or more additional intervening elements are added to indirectly couple or couple the first and second elements to each other.

The present invention provides an exemplary overall configuration of a photovoltaic array support 10 as shown in fig. 1, and fig. 10 to 12 also show the exemplary overall configuration of the photovoltaic array support 10 from different angles, wherein fig. 10 is a schematic view when viewing the photovoltaic array support 10 from the south side, fig. 11 is a schematic view when viewing the photovoltaic array support 10 from obliquely above, and fig. 12 is a schematic view when viewing the photovoltaic array support 10 from obliquely below. The photovoltaic array bracket 10 includes at least two purlins 20 and at least two adjustable brackets 1. The purlins 20 may be, for example, rectangular (or square) tubes, C-section steel, or U-section steel, each shown at A, B, C in fig. 7. It is to be understood that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims. It will also be appreciated that reference numerals may be repeated among the various examples herein for purposes of brevity and clarity and may not, in itself, represent a relationship between the various embodiments and/or structures being discussed.

The at least two purlins 20 are distributed along the north-south direction D1 and are used for supporting the photovoltaic module 30. The photovoltaic module 30 may include a solar panel 301 and a support frame 302, etc., as shown in fig. 10 and 11. Two purlins 20 are shown in fig. 1, one on each of the north and south sides. It will be appreciated that references to directions or orientations herein are not intended to be absolutely consistent, but are to be taken as a range of deviations. For example, "in the north-south direction D1" may be within 10 ° of the actual north-south direction. As another example, a "first direction is perpendicular to a second direction" allows the intersection angle of the first direction and the second direction to deviate within 10 ° from the mathematically required "perpendicular" 90 °. As another example, "the first direction is parallel to the second direction" allows the intersection angle of the first direction and the second direction to be within 10 °.

The aforementioned at least two adjustable supports 1 are distributed along the east-west direction D2, and fig. 1 exemplarily shows four adjustable supports 1 distributed at equal intervals along the east-west direction D2. The at least two purlins 20 are mounted on the at least two adjustable brackets 1 in a east-west direction D2.

Fig. 2A and 2B illustrate the configuration of the adjustable support 1, wherein fig. 2A shows a perspective configuration of the adjustable support 1 and fig. 2B shows a planar configuration of the adjustable support 1. Referring to fig. 1 to 2B, each (set of) adjustable support 1 includes a column 2, a rotating frame 3, and a sprocket 4.

The upright 2 is supported on the ground. For example, the column 2 may include an upper strut 21 and a lower strut 22. For example, the upper support column 21 may be a rectangular pipe, a C-shaped steel, or a circular pipe, as shown in fig. 3A, 3B, and 3C, respectively, and the lower support column 22 may be a column foundation, for example, a precast tubular pile, a cast-in-place concrete pile, a metal tubular pile, or the like. The upper support column 21 may be welded to the top surface of the lower support column 22, for example, by a bottom support plate 211.

The rotating frame 3 is rotatably mounted on the upright 2 and is used for supporting the at least two purlins 20. For example, the top of the upright 2 (in the figure, the upper support 21) may be provided with a connecting hole 212, the top of the rotating frame 3 may also be provided with a corresponding connecting hole 502, and the rotating frame 3 may be rotatably mounted to the upright 2 by passing the rotating shaft 31 (e.g., a cylindrical shaft, a bolt, etc.) through the corresponding connecting holes 212, 502, in other words, the rotating frame 3 may be hinged to the upright 2. The structural form of the rotating frame 3 supporting the purlines 20 and further supporting the photovoltaic modules 30 is lighter and lower in cost than the common form of supporting the photovoltaic modules by using a heavy main beam.

The swivel mount 3 comprises an arc-shaped toothed rack 5. It is understood that the arc-shaped rack 5 means an arc-shaped strip member, such as an arc-shaped strip, having the transmission teeth 51 evenly distributed along an arc line. The chain wheel 4 is in meshed transmission with the arc-shaped rack 5. As shown in fig. 6, the sprocket 4 can be rotatably mounted to the support 41, for example, about a center X0, and the support 41 can be welded to the upright 2, for example. The sprocket 4 and the carrier 41 may constitute a sprocket carrier. Therefore, when the chain wheel 4 rotates, the arc-shaped rack 5 which is meshed with the chain wheel for transmission drives the rotating frame 3 and the purline 20 supported by the rotating frame 3 to rotate, so that the orientation of the photovoltaic module 30 can be adjusted.

In above-mentioned photovoltaic array support 10, sprocket 4 and swivel mount 3's arc rack 5 meshing transmission, therefore rotate predetermined angle through sprocket 4, can adjust photovoltaic module 30's orientation, accommodation process is convenient, and moreover, swivel mount 3 adopts arc rack 5, compares in the form of whole gear, can alleviate whole swivel mount 3's weight and cost, therefore makes accommodation process lighter, easy to carry out.

Referring to fig. 4 and 5, the rotating frame 3 may include a tripod 6 and an inclined beam 7. The tripod 6 may have two side stays 61, 62 and a base stay 63 connected two by two. The aforementioned arc-shaped rack 5 constitutes the shoe 63. The tripod 6 can be rotatably supported to the pillar 2 at the intersection S1 of the two side stays 61, 62, that is, the aforementioned connecting hole 502 is provided at the intersection S1. In the illustrated embodiment, the tripod 6 may further include a middle support 64, and the middle support 64 may be connected between the middle portion of the bottom support 63 and the intersection S1. For example, in the illustrated embodiment, the center brace 64 may extend from the center of the bottom brace 63 to the intersection S1. The "intermediate position of the bottom brace 63" means a substantially midpoint position of a line connecting the connecting position C631 of the bottom brace 63 and the side brace 61 and the connecting position C632 of the bottom brace 63 and the side brace 62. The two side supports 61, 62 or the middle support 64 can also be called as reinforcing ribs, and the whole tripod 6 is structurally stable.

It is understood that specific terms are used herein to describe an embodiment of the invention, such as "one embodiment," "an illustrated embodiment," and/or "another embodiment" to mean a particular feature, structure, or characteristic described in connection with at least one embodiment of the invention. Therefore, it is emphasized and should be appreciated that two or more references to "one embodiment" or "an illustrated embodiment" in various places throughout this specification are not necessarily to the same embodiment. Furthermore, certain features, structures, or characteristics of one or more embodiments of the invention may be combined as appropriate. In addition, the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and if not stated otherwise, the terms do not have special meanings, and therefore, the scope of the present invention should not be construed as being limited.

In the illustrated embodiment, the photovoltaic module 30, the at least two purlins 20, and the rotating frame 3 of the at least two adjustable supports 1 together form a rotating assembly that is rotatable about a rotation center of the rotating frame 3. In other words, all the rotating frames 3 and all the purlins 20 and the photovoltaic modules 30 supported by the rotating frames jointly form a rotating module which can rotate around a rotating center. The photovoltaic array support 10 may be arranged such that the center of gravity of the aforementioned rotating assembly coincides with the aforementioned center of rotation. For example, the center of rotation of the rotating frame 3 may be a horizontal axis, and the center of gravity may be on the horizontal axis. The rotation center of the rotating frame 3 is also the hinged connection point of the upright 2 and the rotating frame 3 or the tripod 6. This makes self-balancing rotation can be realized without the counter weight unit, and then makes the inclination adjust to become light and handy and convenient, and at this moment, photovoltaic array support 10 can be called as self-balancing adjustable support in inclination.

The sloping beam 7 may be connected to the tripod 6 for supporting the aforementioned at least two purlins 20. The oblique beam 7 can be made of rectangular pipe, C-shaped steel or U-shaped steel, for example. Referring to fig. 1, the oblique beam 7 may extend in a north-south direction D1 when it is in a horizontal state. In the illustrated embodiment, the purlin 20 may be perpendicularly cross-connected to the cant rail 7 at an upper portion of the cant rail 7 in the east-west direction D2.

In the illustrated embodiment, the middle portion of the oblique beam 7 may be connected to the portions P1, P2 of the two side supports 61, 62 below the intersection S1, respectively. In the illustrated embodiment, the rotating frame 3 may further include two braces 81 and 82 (in the drawing, a front brace 81 and a rear brace 82). Two braces 81, 82 may each connect one end of the diagonal 7 and a corresponding end of the bottom brace 63. Specifically, in fig. 4, a front sprag 81 connects a front end (in fig. 4, an end on the south side) of the sprag 7 and a front end of the bottom stay 63 of the tripod 3, and a rear sprag 82 connects a rear end (in fig. 4, an end on the north side) of the sprag 7 and a rear end of the bottom stay 63. The diagonal braces 81, 82 may be, for example, rectangular tubes, C-section steel, or U-section steel. The tripod 6, the raker 7 and the two rakers 81, 82 constitute a special swivel frame structure, so that the coincidence of the center of gravity of the swivel frame 3, the purlin 20 and the photovoltaic module 30 with the center of rotation of the swivel frame 3 can be easily achieved by adjusting the distance of the upper end of the tripod 6 (the intersection S1 of the two side braces 61, 62, or the upper end of the middle brace 64) from the raker 7.

Of the two diagonal braces 81, 82, the diagonal brace (front diagonal brace) 81 located on the south side of the tripod 6 is shorter than the diagonal brace (rear diagonal brace) 82 located on the north side of the tripod 6. It is understood that, taking the front diagonal brace 81 as an example, the length of the front diagonal brace 81 means the distance between the connection point Q811 of the front diagonal brace 81 and the diagonal beam 7 and the connection point Q812 of the front diagonal brace 81 and the bottom brace 63. This makes it possible to bias the entire bottom stay 63 south. The connecting position C631 of the bottom brace 63 and the side brace 61 may be coincident with or close to the connecting point Q812 of the front brace 81 and the bottom brace 63, and in the illustrated embodiment, the connecting position C631 is closer to the connecting point Q812.

In the embodiment shown in fig. 1, the arc-shaped rack 5 may be located on the south side of the upright 2 when the sloping beam 7 is in the horizontal state. By "the arc-shaped rack 5 is located on the south side of the upright 2" it is understood that more than 90% of the driving teeth 51 of the arc-shaped rack 5 are located on the south side of the upright 2. In fig. 4, the gear teeth 51 of the arc-shaped rack 5 located on the most north side are located directly below the intersection S1 where the rotation axes are located. In this way, the photovoltaic module 30 can be kept facing straight up or inclined facing south at all times.

In the rotating frame 3, the tripod 6, the oblique beam 7 and the oblique supports 81 and 82 can be connected by fasteners such as bolts or welding. The upper end (the intersection S1 of the two side braces 61, 62), the front (the connection with the front diagonal brace 810) and the lower end (the connection with the rear diagonal brace 82) of the tripod 6 may be all provided with a connection hole. In the tripod 6, the middle support 64, the bottom support 63 and the two side supports 61 and 62 can be connected by welding. The center of the arc rack 5 forming a part of the tripod 6 may coincide with the rotation center of the rotating frame 3, and the sector angle α (which may also be referred to as a radian) of the arc rack 5 may be 50 ° to 55 °.

In the illustrated embodiment, the photovoltaic array support 10 can further include a drive bar 8, as shown in fig. 8. The transmission rod 8 can be passed through the centers X0 of the chain wheels 4 of at least two adjustable supports 1. The driving rod 8 may be, for example, a circular or square pipe, and may pass through a rod hole 213 (shown in fig. 3A, 3B, and 3C) formed in the lower end of the upper column 21 of the column 2. The two ends of the transmission rod 8 can be provided with connecting holes, for example, all the chain wheels 4 of each adjustable bracket 1 can be rigidly connected into a whole, and when one chain wheel 4 is rotated, the other chain wheels 4 can synchronously rotate through the transmission rod 8.

In the illustrated embodiment, the photovoltaic array support 10 may further include a driving unit 9 for driving the chain wheel 4 of one adjustable support 1 of the at least two adjustable supports 1 to rotate. As shown in fig. 6, the driving unit 9 may be, for example, an adjusting handle provided on the chain wheel 4, and the chain wheel 4 may be rotated by hand. In another embodiment shown in fig. 9, the driving unit 9 may be, for example, an electric motor or a hydraulic cylinder, i.e., the sprocket 4 may be automatically rotated in the form of electric or pneumatic rotation, thereby adjusting the tilt angle of the photovoltaic module 30.

The drive unit 9 may be arranged on the west side of the upright 2 of the most west adjustable support 1 of the at least two adjustable supports 1 or the drive unit 9 may be arranged on the east side of the upright 2 of the most east adjustable support 1 of the at least two adjustable supports 1, as shown in fig. 1. In other words, the drive unit 9 is arranged at the upright 2 of the most lateral adjustable support 1 of the at least two adjustable supports 1, and the drive unit 9 is arranged at the opposite side of the upright 2 compared to the other adjustable supports 1.

In the illustrated photovoltaic array support 10, at least two columns 2 are arranged at certain intervals along the east-west direction D2, each column 2 is provided with a chain wheel seat composed of a rotating frame 3, a chain wheel 4 and the like, and a transmission rod 8 connects the chain wheels 4 arranged on the at least two columns 2. At least two purlines 20 are erected between the upright posts 2 on the upper parts of the oblique beams 7 of the rotating frame 3 at certain intervals and perpendicular to the oblique beams 7, and photovoltaic modules 30 are installed on the upper parts of the purlines 20. The arc-shaped rack 5 is driven to push through the rotation of the chain wheel 4 on the side edge, the rotating frame 3 rotates by taking the rotating shaft 31 at the upper end as a circle center, the inclined beam 7 of the rotating frame 3 and the ground inclination angle are adjusted, the chain wheel 4 of each group of adjustable supports 1 synchronously rotates through the transmission rod 8 connected with the chain wheel 4, the angle of each group of rotating frames 3 in each group of adjustable supports 1 is uniform during adjustment, and the adjustment mode can ensure that the installation inclination angle of the photovoltaic module 30 and the ground is adjustable between 0-70 degrees.

Generally, among the above-mentioned photovoltaic array support, the stand can fixed stay subaerial, and the whole well that forms fixed triangular tripod props up the upper end and is connected with the stand top is articulated, and the chain wheel seat is connected with the last pillar lower extreme of stand, and the center pin of sprocket coincides with the pole hole center of the last pillar lower extreme of stand, and the driving tooth and the sprocket meshing of tripod lower extreme arc rack are equipped with the regulation handle on the sprocket on the most eastern or the most western stand in the photovoltaic array support.

When the inclination angle of the photovoltaic array support is adjusted, the photovoltaic assembly is rotated to a required position by rotating the chain wheel, and then the chain wheel is fixed. The operation workload of adjusting the inclination angle of the photovoltaic module is extremely small, and the loosening phenomenon cannot be generated. The photovoltaic array bracket can also obviously save the cost of materials, installation, transportation and the like.
