Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic supports, and in particular to an adjustable photovoltaic support column connection structure and method. Background Art

[0002] Photovoltaic mounting systems are an integral part of photovoltaic power generation systems, primarily used to support and secure photovoltaic modules. Conventional photovoltaic mounting systems primarily consist of upright posts, diagonal beams, and horizontal beams. These adjustable posts, diagonal beams, and horizontal beams ensure the supported photovoltaic modules receive sunlight at the optimal angle and direction.

[0003] The utility model, publication number CN221862755U, proposes a photovoltaic bracket and a connecting structure for an inclined beam and purlin for the photovoltaic bracket. The connecting structure for the inclined beam and purlin of the photovoltaic bracket includes: an inclined beam for mounting to the column of the photovoltaic bracket; a purlin supported by the inclined beam, the purlin being used to support the photovoltaic module; and an L-shaped connector, the L-shaped connector including a first section and a second section connected to each other, the first section being connected to the inclined beam, the first section being provided with a plurality of position adjustment holes along the length of the inclined beam, and the second section being connected to the purlin.

[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 limit rod is adjusted to rotate along the rotating drum. At this time, the rotating drum rotates under the limit of the first connecting shaft. The limit rod drives the sliding seat to slide synchronously through the connecting block and the hinge block. By positioning the rotation angle of the limit rod, the desired rotation angle of the inclined beam can be positioned. The sliding seat slides synchronously for a certain distance.

[0035] (2) By setting the distance ratio between the first connecting shaft and the second connecting shaft, the distance between the first connecting shaft and the second connecting shaft is prevented from being too short, which causes the inclined beam to rotate unstably. At the same time, the distance between the first connecting shaft and the second connecting shaft is prevented from being too long, which causes the end of the inclined beam to extend too long.

After the position of the connecting frame is adjusted, the first connecting screw is passed through the connector and the clamping sleeve, and the first clamping nut is connected to the first connecting screw and rotated, so that the connecting frame is squeezed by the first clamping nut, and the connecting frame is compressed by pressing the clamping sleeve to the connector, thereby completing the positioning processing of the rotation position of the connecting frame, which is convenient for use.

This design facilitates the connection between the column 1 and the external base. The top end of the column 1 has a hollow square cross-section. This design facilitates the rotational connection between the column 1 and the inclined beam 2, as well as the connection to other components.

[0051] In a specific implementation, a thread is provided on the first connecting shaft 31 , and a limiting nut 34 is threadedly connected to the first connecting shaft 31 .

[0052] In a specific implementation, before adjusting the rotation of the inclined beam 2, the adjustment limit rod 42 is rotated along the rotating drum 41. At this time, the rotating drum 41 rotates under the limit of the first connecting shaft 31, and the limit rod 42 synchronously drives the sliding seat 43 to slide through the connecting block 44 and the hinge block 45. By positioning the rotation angle of the limit rod 42, the desired rotation angle of the inclined beam 2 can be completed. The sliding seat 43 synchronously slides a certain distance, and by rotating the clamping screw 46, the clamping screw 46 is pressed against the inside of the matching groove 11, thereby completing the positioning of the limit rod 42 by fixing the sliding seat 43. After the positioning of the limit rod 42 is completed, the rotation of the inclined beam 2 is adjusted again. At this time, the limit rod 42 can block the inclined beam 2 from one side of the inclined beam 2, so that the heavy inclined beam 2 can be rotated to the desired angle, and the rotation angle is accurate and convenient to use.

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

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

[0055] It also includes a dial 47 and a pointer 48 , wherein the dial 47 is arranged on the circumference of the drum 41 and has scale lines on it; the pointer 48 is arranged on the column 1 and the end of the pointer 48 extends to the scale lines on the dial 47 .

[0056] In a specific implementation, the scale plate 47 is provided at the end of the drum 41 and is in contact with the inner wall of the column 1. This design increases the rotational connection stability of the drum 41 and facilitates the extension of the pointer 48 provided on the inner wall of the column 1 to the scale plate 47.

[0057] In a specific implementation, when adjusting the rotation of the limit rod 42 , the rotation angle of the limit rod 42 can be quickly determined by observing the position corresponding to the pointer 48 on the dial 47 , which is convenient for use.

[0058] As a preferred embodiment, it also includes a second connecting shaft 32 and a first clamping nut 33, wherein the second connecting shaft 32 is arranged on the column 1, and a sliding hole 211 for the second connecting shaft 32 to pass through is opened on the inclined beam 2; the second connecting shaft 32 is provided with a thread, and the first clamping nut 33 is threadedly connected to the second connecting shaft 32 for clamping the inclined beam 2.

[0059] In a specific implementation, when adjusting the rotation of the inclined beam 2, 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 threadedly connected to the second connecting shaft 32 is rotated. At this time, the first clamping nut 33 completes the positioning of the rotation position of the inclined beam 2 by squeezing the column 1.

[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 distance between the first connecting shaft 31 and the second connecting shaft 32 from being too short, which would cause the inclined beam 2 to rotate unstably. At the same time, it prevents the distance between the first connecting shaft 31 and the second connecting shaft 32 from being too long, which would cause the end of the inclined beam 2 to extend too long. By reducing the extension distance of the end of the inclined beam 2, the design cost of the inclined beam 2 is reduced, making it easier to use.

[0063] Specifically, the first mounting beam 21 and the second mounting beam 22 are both square frames.

By connecting bolts 23 to positioning holes 24 at different positions, the second mounting beam 22 is positioned relative to the first mounting beam 21.

[0065] By setting the inclined beam 2 to be connected to the connecting frame 6 through the connecting component 5, and the connecting frame 6 is used to connect external cross beams and other components, the connecting frame 6 of the present application can rotate around the end of the inclined beam 2 when connected. By setting the rotation direction of the connecting frame 6 to be perpendicular to the rotation direction of the inclined beam 2, the photovoltaic components connected to the photovoltaic bracket of the present application can be deflected and adjusted in multiple directions.

[0066] In a specific implementation, after the position of the connecting frame 6 is adjusted, the first connecting screw 52 is passed 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, so that the connecting frame 6 is squeezed by the second clamping nut 53, and the connecting frame 6 is compressed by pressing the clamping sleeve 54 to tighten the connecting body 51, thereby completing the positioning processing of the rotation position of the connecting frame 6, which is convenient for use.

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

[0069] In a specific implementation, the photovoltaic module connection cables are positioned by passing them through the threading holes on the threading frame 72. The threading frame 72 is adjusted to rotate along the outer connecting frame 71 and the third compression nut 74 is rotated to complete the positioning of the threading frame 72, making it easy to use.

[0070] The present invention also proposes a method for connecting an adjustable photovoltaic support column, comprising the above-mentioned adjustable photovoltaic support column connection structure, and further comprising the following steps:

[0071] Step 1: According to the required rotation angle of the inclined beam 2, the rotating drum 41 is adjusted to rotate. In this step, the rotating drum 41 is used to block the inclined beam 2 at the required rotation position of the inclined beam 2. During the rotation, the position corresponding to the pointer 48 on the dial 47 is observed to complete the judgment process of the rotation angle of the rotating drum 41;

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

[0073] Step 3: Adjust the inclined beam 2 to rotate until the side wall of the inclined beam 2 contacts the limiting rod 42;

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