Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to an adjustable photovoltaic support column connection structure and method. Background Technology

[0002] Photovoltaic (PV) mounting systems are an indispensable component of photovoltaic (PV) power generation systems, primarily used to support and secure PV modules. A typical PV mounting system mainly consists of columns, diagonal beams, and horizontal beams. By adjusting the angles of these components, the system ensures that the supported PV modules receive sunlight at the optimal angle and direction.

[0003] Utility model patent CN221862755U discloses a photovoltaic (PV) bracket and a beam-purlin connection structure for the PV bracket. The beam-purlin connection structure includes: a beam for mounting to a column of the PV bracket; purlins supported by the beam for supporting PV modules; and an L-shaped connector comprising a first section and a second section connected to each other. The first section is connected to the beam and has multiple position adjustment holes along the length of the beam. The second section is connected to the purlins. Conventional PV brackets often allow the beam to rotate around the column when connected, making the connection angle of the beam adjustable and thus the position of the connected PV modules adjustable. However, in the existing connection structure between the column and the inclined beam, there is no positioning device for the rotation angle of the inclined beam. Since other beams for connecting photovoltaic modules are also connected to the inclined beam, the weight of the components carried by the inclined beam is relatively large. It is inconvenient to accurately position the rotation angle of the heavy inclined beam when adjusting its rotation. Therefore, this solution proposes an adjustable photovoltaic support column connection structure and method to solve the above problems. Summary of the Invention

[0022] The connector is mounted on the second mounting beam;

[0023] A first connecting screw passes through the connecting frame and the connecting body, and a second clamping nut is threadedly connected to the first connecting screw;

[0024] A clamping sleeve is fitted onto the first connecting screw and located between the connecting frame and the connecting body, for pressing the connecting frame and the connecting body together.

[0028] This invention also proposes an adjustable photovoltaic support column connection method, including the above-mentioned adjustable photovoltaic support column connection structure, and further including the following steps:

[0029] S1. Adjust the rotation of the drum according to the required rotation angle of the inclined beam;

[0031] S3. Adjust the rotation of the inclined beam until the side wall of the inclined beam touches the limit rod;

[0032] S4. Fix the rotation position of the inclined beam to complete the precise adjustment of the rotation angle of the inclined beam.

[0033] The adjustable photovoltaic support column connection structure and method of the present invention have the following advantages over the prior art:

[0034] (1) Before adjusting the rotation of the inclined beam, the limiting rod is adjusted to rotate along the rotating cylinder. At this time, the rotating cylinder rotates under the limit of the first connecting shaft. The limiting rod drives the sliding seat to slide synchronously through the connecting block and the hinge block. By positioning the rotation angle of the limiting rod, the required rotation angle of the inclined beam can be completed. The sliding seat slides synchronously a certain distance. By rotating the clamping screw, the clamping screw is pressed into the inside of the mating groove, thereby completing the positioning of the limiting rod by fixing the sliding seat. After the limiting rod is positioned, the inclined beam is adjusted to rotate. At this time, the limiting rod can block the inclined beam from one side, so that the heavy inclined beam can rotate to the ideal angle with accurate rotation angle, which is convenient to use.

[0035] (2) By setting the distance ratio between the first and second connecting shafts, the instability of the inclined beam rotation is prevented due to the short distance between the first and second connecting shafts, and the excessive extension of the inclined beam end is prevented due to the excessive distance between the first and second connecting shafts. Thus, by reducing the extension distance of the inclined beam end, the design cost of the inclined beam is reduced and it is convenient to use.

[0036] (3) By setting an inclined beam connected to the connecting frame via a connecting component, and the connecting frame being used to connect external crossbeams and other components, the connecting frame of this application can rotate around the end of the inclined beam during connection. By setting the rotation direction of the connecting frame to be perpendicular to the rotation direction of the inclined beam, the photovoltaic modules connected to the photovoltaic bracket of this application can be deflected and adjusted in multiple dimensions. After the position of the connecting frame is adjusted, the first connecting screw passes through the connecting body and the clamping sleeve, and the first clamping nut is connected to the first connecting screw and rotated, thereby squeezing the connecting frame through the first clamping nut. The connecting frame then presses the clamping sleeve to clamp the connecting body, thus completing the positioning process of the rotating position of the connecting frame, which is convenient for use.

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] like Figures 1-9As shown, the adjustable photovoltaic support column connection structure of the present invention includes a column 1, an inclined beam 2, a rotating cylinder 41, a limiting rod 42, a sliding seat 43, a connecting block 44, a hinge block 45, and a clamping screw 46. The inclined beam 2 is rotatably connected to the end of the column 1 via a first connecting shaft 31. The rotating cylinder 41 is sleeved on the first connecting shaft 31, and the limiting rod 42 is fixedly connected to the rotating cylinder 41. The limiting rod 42 is used to block the inclined beam 2 in the rotation path of the inclined beam 2. The sliding seat 43 is slidably disposed on the column 1 and slides towards or away from the rotating cylinder 41. The connecting block 44 is disposed on the limiting rod 42, and one end of the hinge block 45 is hinged to the connecting block 44, and the other end of the hinge block 45 is hinged to the sliding seat 43. The clamping screw 46 is threadedly connected to the sliding seat 43, and a mating groove 11 is provided on the column 1, into which the clamping screw 46 is inserted.

[0050] In practice, the installation of column 1 is completed by inserting it into the interior of the external base. The lower section of column 1 is circular. This design facilitates the connection between column 1 and the external base. The upper section of column 1 is hollow square. This design facilitates the rotational connection between column 1 and the inclined beam 2, and also facilitates the connection with other components.

[0051] In practice, the first coupling 31 is provided with threads, and the first coupling 31 is threadedly connected to a limit nut 34.

[0052] In practice, before adjusting the rotation of the inclined beam 2, the adjusting limit rod 42 rotates along the rotating cylinder 41. At this time, the rotating cylinder 41 rotates under the limit of the first connecting shaft 31. The limit rod 42 drives the sliding seat 43 to slide synchronously through the connecting block 44 and the hinge block 45. By positioning the rotation angle of the limiting rod 42, the positioning treatment of the required rotation angle of the inclined beam 2 can be completed. The sliding seat 43 slides synchronously a certain distance, and by rotating the clamping screw 46, the clamping screw 46 is pressed into the interior of the mating groove 11, thereby completing the positioning treatment of the limiting rod 42 by fixing the sliding seat 43. After the limiting rod 42 is positioned, the inclined beam 2 is adjusted to rotate. At this time, the limiting rod 42 can block the inclined beam 2 from one side, so that the heavy inclined beam 2 can rotate to the ideal angle with precision, which is convenient to use.

[0053] In a preferred embodiment, the rotating drum 41 is fixedly connected to the limiting rod 42 via a connecting plate, the column 1 is a square column, and a clearance groove 12 is provided on one side of the end of the column 1 for the connecting plate to pass through.

[0054] This design facilitates the connection between the rotating drum 41 and the external limiting rod 42, and the setting of the clearance groove 12 facilitates the free rotation of the connecting plate.

[0055] It also includes a dial 47 and a pointer 48. The dial 47 is disposed on the periphery of the rotating cylinder 41 and is provided with scale lines. The pointer 48 is disposed on the column 1 and the end of the pointer 48 extends to the scale line on the dial 47.

[0056] In practice, the dial 47 is located at the end of the rotating cylinder 41 and fits against the inner wall of the column 1. This design increases the rotational stability of the rotating cylinder 41 and also facilitates the extension of the pointer 48, which is located on the inner wall of the column 1, to the dial 47.

[0057] In practice, when adjusting the rotation of the limit rod 42, the position of the pointer 48 on the scale 47 is observed to quickly determine the rotation angle of the limit rod 42, which is convenient to use.

[0058] In a preferred embodiment, the device further includes a second coupling 32 and a first clamping nut 33. The second coupling 32 is mounted on the column 1, and the inclined beam 2 has a sliding hole 211 through which the second coupling 32 passes. The second coupling 32 is threaded, and the first clamping nut 33 is threadedly connected to the second coupling 32 to clamp the inclined beam 2.

[0059] In practice, when the inclined beam 2 is rotated, the second connecting shaft 32 slides synchronously along the sliding hole 211. When the inclined beam 2 rotates to the ideal position, the first clamping nut 33, which is threadedly connected to the second connecting shaft 32, rotates. At this time, the first clamping nut 33 presses the column 1 to complete the positioning of the inclined beam 2.

[0060] The first connecting shaft 31 and the second connecting shaft 32 are distributed in the vertical direction. The distance between the first connecting shaft 31 and the second connecting shaft 32 is a, and the distance between the second connecting shaft 32 and the end of the inclined beam 2 is b. 2∶1≤a∶b≤4∶1.

[0061] This design prevents the inclined beam 2 from rotating unstable due to an excessively short distance between the first connecting shaft 31 and the second connecting shaft 32, while also preventing the inclined beam 2 from extending too far due to an excessively long distance between the first connecting shaft 31 and the second connecting shaft 32. In this way, by reducing the extension distance at the end of the inclined beam 2, the design cost of the inclined beam 2 is reduced, and it is easier to use.

[0062] In a preferred embodiment, the inclined beam 2 includes a first mounting beam 21 and a second mounting beam 22, wherein the second mounting beam 22 is connected to the first mounting beam 21 by connecting bolts 23, and the first mounting beam 21 has a plurality of positioning holes 24 for the connecting bolts 23 to pass through, and the plurality of positioning holes 24 are equidistantly distributed in the extension direction of the first mounting beam 21.

[0063] In specific implementation, both the first mounting beam 21 and the second mounting beam 22 are square frames. The second mounting beam 22 is inserted into the interior of the column 1, allowing the column 1 to rotate normally without affecting the inclined beam 2. By connecting the connecting bolts 23 to the positioning holes 24 at different positions, the positioning of the second mounting beam 22 relative to the first mounting beam 21 is completed.

[0064] In a preferred embodiment, the second mounting beam 22 is connected to the connecting frame 6 via a connecting component 5. The connecting component 5 includes a connecting body 51, a first connecting screw 52, ​​a second clamping nut 53, and a clamping sleeve 54. The connecting body 51 is disposed on the second mounting beam 22. The first connecting screw 52 passes through the connecting frame 6 and the connecting body 51, and the second clamping nut 53 is threadedly connected to the first connecting screw 52. The clamping sleeve 54 is sleeved on the first connecting screw 52 and is located between the connecting frame 6 and the connecting body 51 to compress the connecting frame 6 and the connecting body 51.

[0065] By setting the inclined beam 2 to be connected to the connecting frame 6 via the connecting component 5, and the connecting frame 6 being used to connect external crossbeams and other components, the connecting frame 6 of this application can rotate around the end of the inclined beam 2 during connection. By setting the rotation direction of the connecting frame 6 to be perpendicular to the rotation direction of the inclined beam 2, the photovoltaic modules connected to the photovoltaic bracket of this application can be deflected and adjusted in multiple dimensions.

[0066] In practice, after the position of the connecting frame 6 is adjusted, the first connecting screw 52 passes through the connecting body 51 and the clamping sleeve 54, and the second clamping nut 53 is connected to the first connecting screw 52 and rotated. The second clamping nut 53 then presses the connecting frame 6, and the connecting frame 6 presses the clamping sleeve 54 to clamp the connecting body 51, thereby completing the positioning of the rotating position of the connecting frame 6 for convenient use.

[0067] The connecting frame 6 is a concave square frame, and there are two connecting frames 6. The two connecting frames 6 are located on opposite sides of the connecting body 51. There are two clamping sleeves 54, and the clamping sleeves 54 are respectively fitted between the two connecting frames 6 and the connecting body 51.

[0068] In a preferred embodiment, the device further includes an outer connecting frame 71, a wire threading frame 72, and a second connecting screw 73. The outer connecting frame 71 is mounted on the column 1, and the wire threading frame 72 is rotatably connected to the outer connecting frame 71 via the second connecting screw 73. A third clamping nut 74 is threaded onto the second connecting screw 73.

[0069] In practice, the photovoltaic module's connecting cables are positioned by passing them through the holes on the cable guide 72. The cable guide 72 is positioned by adjusting its rotation along the outer connecting frame 71 and by rotating the third clamping nut 74, making it convenient to use.

[0070] This invention also proposes an adjustable photovoltaic support column connection method, including the above-mentioned adjustable photovoltaic support column connection structure, and further including the following steps:

[0071] Step 1: Adjust the rotation of the rotating cylinder 41 according to the required rotation angle of the inclined beam 2. In this step, the rotating cylinder 41 is used to block the inclined beam 2 at the required rotation position. During the rotation, the position of the pointer 48 on the scale 47 is observed to complete the judgment and processing of the rotation angle of the rotating cylinder 41.

[0072] Step 2: Rotate the clamping screw 46. At this time, the clamping screw 46 is pressed into the inside of the mating groove 11, completing the positioning process of the rotation position of the limit rod 42.

[0073] Step 3: Adjust the rotation of the inclined beam 2 until the side wall of the inclined beam 2 abuts against the limit rod 42;

[0074] Step 4: Fix the rotation position of the inclined beam 2 by rotating the first clamping nut 33, thereby completing the precise adjustment of the rotation angle of the inclined beam 2.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
