[0034] The adjustable photovoltaic support beam connection structure and method of the present invention have the following advantages over the prior art:

[0035] (1) By setting the connecting steel pipe to be pulled between the beam and the column, the connecting steel pipe can be moved synchronously when adjusting the deflection angle of the beam. After the position of the beam is adjusted, it is only necessary to rotate the first clamping bolt and the second clamping bolt to complete the preliminary positioning of the beam position by fixing the position of the connecting steel pipe.

DETAILED DESCRIPTION

[0046] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] like Figures 1 to 6As shown, the adjustable photovoltaic bracket beam connection structure of the present invention includes a column 11, an inclined beam 12, a connecting beam 13, a cross beam 14, a pipe connector 2, a connecting steel pipe 3 and a first cross beam connector 4, the pipe connector 2 includes a first clamping rod frame 21, a first side connector 22, a first clamping bolt 23, a pipe connecting frame 24 and a second clamping bolt 25, wherein the inclined beam 12 is rotatably set on the column 11, and the connecting beam 13 is rotatably connected to the inclined beam 12, and the cross beam 14 is slidably connected to the connecting beam 13; the first clamping rod frame 21 is sleeved on the column 11 , and passes through the first side connector 22, the first clamping bolt 23 is threadedly connected to the first clamping rod frame 21, used to squeeze the first side connector 22; the two pipe connecting frames 24 are both rotatably set on the first side connector 22, and the connecting steel pipe 3 passes between the two pipe connecting frames 24, and the connecting steel pipe 3 is an arc-shaped pipe; the second clamping bolt 25 is threadedly connected between the two pipe connecting frames 24, used to adjust the distance between the ends of the two pipe connecting frames 24; the first crossbeam connector 4 is connected to the crossbeam 14, and the end of the connecting steel pipe 3 is hinged to the first crossbeam connector 4.

[0048] In a specific implementation, the upright column 11 , the inclined beam 12 , the connecting beam 13 and the cross beam 14 are all square beams, and the rotation angles of the inclined beam 12 and the connecting beam 13 are perpendicular to each other.

[0049] In a specific implementation, there are multiple cross beams 14 , and both ends of the connecting steel pipe 3 are respectively connected to the cross beams 14 on both sides, and the cross beams 14 on both sides are symmetrically distributed relative to the columns 11 .

[0050] In specific implementation, the connecting steel pipe 3 is passed between the two pipe connecting frames 24, and both ends of the connecting steel pipe 3 are connected to the crossbeam 14 via the first crossbeam connector 4. The tilting beam 12 and the connecting beam 13 are then adjusted to rotate. The first clamping rod 21 moves along the column 11, and the connecting steel pipe 3 moves and rotates along the pipe connecting frame 24. The first and second clamping bolts 23 and 25 are then rotated. The first clamping bolt 23 secures the position of the first clamping rod 21 relative to the column 11, while the second clamping bolt 25 secures the position of the connecting steel pipe 3 relative to the pipe connecting frame 24, thus completing the initial positioning of the crossbeam 14. After the crossbeam 14 is initially positioned, the rotation angles of the tilting beam 12 and the connecting beam 13 are then fixed in sequence, completing the securement of the crossbeam 14.

[0051] By setting the connecting steel pipe 3 to be pulled between the crossbeam 14 and the column 11, the connecting steel pipe 3 can move synchronously when adjusting the deflection angle of the crossbeam 14. After the position of the crossbeam 14 is adjusted, it is only necessary to rotate the first clamping bolt 23 and the second clamping bolt 25 to complete the preliminary positioning of the position of the crossbeam 14 by fixing the position of the connecting steel pipe 3. Since the first clamping bolt 23 and the second clamping bolt 25 are both located at the connection between the connecting steel pipe 3 and the column 11, it is convenient to preliminarily position the position of the crossbeam 14. After the crossbeam 14 is preliminarily positioned, the rotation angles of the inclined beam 12 and the connecting beam 13 are fixed in turn to complete the precise positioning of the crossbeam 14, which is convenient for use.

[0052] like Figure 2 As shown, as a preferred embodiment, the first crossbeam connector 4 includes a second clamping rod frame 41, a second side connector 42 and a third clamping bolt 43, wherein the second clamping rod frame 41 is sleeved on the outer side of the crossbeam 14 and passes through the second side connector 42, and the third clamping bolt 43 is threadedly connected to the second clamping rod frame 41 for squeezing the second side connector 42.

[0053] In the specific implementation, the second clamping rod frame 41 is sleeved on the outside of the beam 14, and the second side connecting body 42 is passed through the second clamping rod frame 41, and the third clamping bolt 43 is threadedly connected to the second clamping rod frame 41 and rotated. The second side connecting body 42 is squeezed by the third clamping bolt 43, thereby completing the connection between the connecting steel pipe 3 and the beam 14.

[0054] The second side connector 42 is a U-shaped member, and a connecting gap 421 is formed between the two side walls of the second side connector 42 . The connecting steel pipe 3 is hinged on the inner side of the connecting gap 421 , and the third clamping bolt 43 is threadedly connected to the inner side of the connecting gap 421 .

[0055] This design is used to increase the connection stability of the third clamping bolt 43 under the shielding of the second side connecting body 42 .

[0056] like Figures 1 to 3 As shown, as a preferred embodiment, the columns 11 and the crossbeams 14 are both square beams, the pipe connecting frame 24 is an arc-shaped frame, and the first clamping rod frame 21 and the second clamping rod frame 41 are both U-shaped frames.

[0057] This design allows for large-surface contact with the connected steel pipe 3 when the pipe connecting frame 24 is used to securely connect the steel pipe 3, thereby improving the connection stability of the pipe connecting frame 24. By providing both the first clamping rod frame 21 and the second clamping rod frame 41 as U-shaped frames, large-surface contact with the column 11 and the crossbeam 14 when the first clamping rod frame 21 and the second clamping rod frame 41 are used to clamp the column 11 and the crossbeam 14, thereby improving the connection stability of the first clamping rod frame 21 and the second clamping rod frame 41.

[0058] like Figure 2 As shown, as a preferred embodiment, it also includes a sliding sleeve 51, an elastic pressure piece 52 and a clamping rod 53, wherein the sliding sleeve 51 is sleeved on the beam 14, and the second clamping rod frame 41 is sleeved on the sliding sleeve 51; the elastic pressure piece 52 is arranged on the sliding sleeve 51, and the clamping rod 53 is rotatably arranged on the sliding sleeve 51. When the clamping rod 53 rotates, the clamping rod 53 squeezes the elastic pressure piece 52 toward the side close to the beam 14.

[0059] By setting the second clamping rod frame 41 to be sleeved on the sliding sleeve 51, when it is necessary to adjust the cross beam 14 to move along the connecting beam 13 for fine-tuning, there is no need to adjust the connection state of the first cross beam connector 4. The clamping rod 53 is bent to rotate the clamping rod 53 to disengage from the elastic pressing piece 52. The elastic pressing piece 52 releases the cross beam 14, so that the cross beam 14 can move along the sliding sleeve 51, which is convenient for adjusting the cross beam 14 to move along the connecting beam 13 for fine-tuning after the first cross beam connector 4 is connected, which is convenient for use.

[0060] The pressing rod 53 is provided with a control rod 54 .

[0061] This design facilitates the regulation and rotation of the pressing rod 53.

[0062] like Figures 4-5 As shown, as a preferred embodiment, the connecting beam 13 is connected to the cross beam 14 through the second cross beam connector 6, and the second cross beam connector 6 includes a third clamping rod frame 61, a connecting plate 62, a limiting baffle 63 and a fourth clamping bolt 64, wherein the connecting beam 13 includes two side beams 131, and the side beams 131 are provided with connecting holes 1311; the third clamping rod frame 61 is sleeved on the cross beam 14 and passes through the connecting plate 62, and the connecting plate 62 passes through the two connecting holes 1311; the limiting baffle 63 is provided on the connecting plate 62, for limiting the connecting plate 62 from detaching from the side beam 131; the fourth clamping bolt 64 is threadedly connected to the third clamping rod frame 61, for squeezing the connecting plate 62.

[0063] It should be noted that, in the prior art, the connection method between the connecting beam 13 and the cross beam 14 is: the cross beam 14 must be connected with the two side beams 131, and the existing connection position is to add U-shaped steel plates at both ends of the inner side of the two side beams 131, and the web is matched with the cross beam 14 through two U-shaped bolts facing outward, and the flange is connected to the two side beams 131 through four bolts.

[0064] By setting up a third clamping rod frame 61 connected to the connecting beam 13 through a connecting plate 62, when connecting the cross beam 14 and the connecting beam 13, it is only necessary to rotate the fourth clamping bolt 64 to connect the cross beam 14 to the two side beams 131. Compared with the existing method of cooperating with the cross beam 14 through two U-shaped bolts and connecting the flange to the two side beams 131 through four bolts, the second cross beam connector 6 of the present application can reduce the complexity of connection and reduce costs.

[0065] like Figure 6 As shown, as a preferred embodiment, the crossbeam 14 is connected to the mounting beam 15 through the third crossbeam connector 7, and the third crossbeam connector 7 includes a fourth clamping rod frame 71, a third side connector 72 and a fifth clamping bolt 73, wherein the fourth clamping rod frame 71 passes through the mounting beam 15 and the third side connector 72, and is sleeved on the circumference of the crossbeam 14, and the mounting beam 15 and the third side connector 72 are respectively located on opposite sides of the crossbeam 14; the fifth clamping bolt 73 is threadedly connected to the fourth clamping rod frame 71, and is used to squeeze the third side connector 72 toward the side close to the crossbeam 14; a connecting groove 151 is opened on the mounting beam 15, and the fourth clamping rod frame 71 is located on the inner side of the connecting groove 151.

[0066] In a specific implementation, the mounting beam 15 is used to connect to the external photovoltaic module bracket. The mounting beam 15 is connected to the photovoltaic module bracket by bolts, and the photovoltaic module bracket is distributed in an array on the mounting beam 15.

[0067] In the specific implementation, the fourth clamping rod frame 71 is passed through the inner side of the connecting groove 151 and is sleeved on the outer side of the beam 14, the third side connecting body 72 is passed through the fourth clamping rod frame 71, and the fifth clamping bolt 73 is threadedly connected to the fourth clamping rod frame 71. By squeezing the third side connecting body 72, the connection between the beam 14 and the mounting beam 15 is completed.

[0068] By arranging the fourth clamping rod 71 at the inner side of the connecting groove 151 and shielded by the groove wall of the connecting groove 151 , the connection stability of the fourth clamping rod 71 can be increased.

[0069] The present invention also proposes a method for connecting an adjustable photovoltaic support beam, comprising the above-mentioned adjustable photovoltaic support beam connection structure, and further comprising the following steps:

[0070] Step 1: Pass the connecting steel pipe 3 between the two pipe connecting frames 24, and connect the two ends of the connecting steel pipe 3 to the crossbeam 14 through the first crossbeam connector 4;

[0071] Step 2: Adjust the tilt beam 12 and the connecting beam 13 to rotate. At this time, the first clamping rod frame 21 moves along the column 11, and the connecting steel pipe 3 moves circumferentially and rotates along the pipe connecting frame 24;

[0072] Step 3: Rotate the first clamping bolt 23 and the second clamping bolt 25. The first clamping bolt 23 fixes the position of the first clamping rod frame 21 relative to the column 11, and the second clamping bolt 25 fixes the position of the connecting steel pipe 3 relative to the pipe connecting frame 24.

[0073] Step 4: Fix the rotation angles of the inclined beam 12 and the connecting beam 13 in sequence.

[0074] It should be noted that the clamping rod frames of the present application are all U-shaped rod frames, and the fifth clamping bolt 73 is connected to the inner side of the third side connecting body 72 .

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