[0029] The present invention also proposes an adjustable photovoltaic support beam connection method, including the above-mentioned adjustable photovoltaic support beam connection structure, and further including the following steps:

[0030] S1. Pass the connecting steel pipe between the two pipe connecting brackets, and connect both ends of the connecting steel pipe to the crossbeam through the first crossbeam connector;

[0031] S2. Adjust the rotation of the inclined beam and connecting beam;

[0032] S3. Rotate the first clamping bolt and the second clamping bolt. At this time, the first clamping bolt fixes the position of the first clamping rod relative to the column, and the second clamping bolt fixes the position of the connecting steel pipe relative to the pipe connecting frame.

[0033] S4. Fix the rotation angles of the inclined beam and the connecting beam in sequence.

[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 a connecting steel pipe to pull between the crossbeam and the column, the connecting steel pipe can move synchronously when adjusting the deflection angle of the crossbeam. After the position of the crossbeam is adjusted, only the first clamping bolt and the second clamping bolt need to be rotated to fix the position of the connecting steel pipe and complete the preliminary positioning of the crossbeam. Since the first clamping bolt and the second clamping bolt are both located at the connection between the connecting steel pipe and the column, it is convenient to preliminarily position the crossbeam. After the crossbeam is preliminarily positioned, the rotation angles of the inclined beam and the connecting beam are fixed in sequence to complete the precise positioning of the crossbeam, which is convenient for use.

[0036] (2) By setting the second clamping rod bracket on the sliding sleeve, when it is necessary to adjust the crossbeam to move along the connecting beam for fine adjustment, there is no need to adjust the connection state of the first crossbeam connector. Just pry the clamping rod to rotate it until it is disengaged from the elastic pressure plate. The elastic pressure plate releases the crossbeam, allowing the crossbeam to move along the sliding sleeve. This makes it convenient to adjust the crossbeam to move along the connecting beam for fine adjustment after the first crossbeam connector is connected, which is convenient to use.

[0037] (3) By setting a third clamping rod frame to connect with the connecting beam through the connecting piece, when connecting the crossbeam and the connecting beam, only the fourth clamping bolt needs to be rotated to connect the crossbeam to the two side beams. Compared with the existing method of connecting the crossbeam with two U-bolts and connecting the flange to the two side beams with four bolts, the second crossbeam connector of this application can reduce the complexity of the connection and reduce the cost.

[0046] 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.

[0047] like Figures 1-6As shown, the adjustable photovoltaic support beam connection structure of the present invention includes a column 11, an inclined beam 12, a connecting beam 13, a crossbeam 14, a pipe connector 2, a connecting steel pipe 3, and a first crossbeam connector 4. The pipe connector 2 includes a first clamping rod 21, a first side connector 22, a first clamping bolt 23, a pipe connector 24, and a second clamping bolt 25. The inclined beam 12 is rotatably mounted on the column 11, and the connecting beam 13 is rotatably connected to the inclined beam 12. The crossbeam 14 is slidably connected to the connecting beam 13. The first clamping rod 21 is sleeved on the column 11. The first clamping bolt 23 is threaded onto the first clamping rod 21 and is used to press the first side connecting body 22. Both pipe connecting frames 24 are rotatably mounted on the first side connecting body 22, and the connecting steel pipe 3 passes between the two pipe connecting frames 24. The connecting steel pipe 3 is an arc-shaped pipe. The second clamping bolt 25 is threaded between the two pipe connecting frames 24 and is used to adjust the distance between the ends of the two pipe connecting frames 24. The first crossbeam connecting piece 4 is connected to the crossbeam 14, and the end of the connecting steel pipe 3 is hinged to the first crossbeam connecting piece 4.

[0048] In practice, the column 11, the inclined beam 12, the connecting beam 13, and the crossbeam 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 practice, there are multiple crossbeams 14, and the two ends of the connecting steel pipe 3 are connected to the crossbeams 14 on both sides respectively. The crossbeams 14 on both sides are symmetrically distributed relative to the column 11.

[0050] In practice, 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 through the first crossbeam connector 4. Then, the tilting beam 12 and the connecting beam 13 are rotated. At this time, 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. Then, the first clamping bolt 23 and the second clamping bolt 25 are rotated. At this time, the first clamping bolt 23 fixes the position of the first clamping rod 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, thus completing the initial positioning of the crossbeam 14. After the initial positioning of the crossbeam 14, the rotation angles of the tilting beam 12 and the connecting beam 13 are fixed in sequence, thus completing the fixing of the crossbeam 14.

[0051] By setting a 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, only the first clamping bolt 23 and the second clamping bolt 25 need to be rotated to fix the position of the connecting steel pipe 3, thus completing the preliminary positioning of the crossbeam 14. 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 perform the preliminary positioning of the crossbeam 14. After the crossbeam 14 is initially positioned, the rotation angles of the inclined beam 12 and the connecting beam 13 are fixed in sequence to complete the precise positioning of the crossbeam 14, which is convenient for use.

[0052] like Figure 2 As shown, in a preferred embodiment, the first crossbeam connector 4 includes a second clamping rod 41, a second side connector 42, and a third clamping bolt 43. The second clamping rod 41 is sleeved on the outside of the crossbeam 14 and passes through the second side connector 42. The third clamping bolt 43 is threaded onto the second clamping rod 41 and is used to press the second side connector 42.

[0053] In practice, the second clamping rod 41 is fitted onto the outside of the crossbeam 14, and the second side connector 42 is passed through the second clamping rod 41. The third clamping bolt 43 is threaded onto the second clamping rod 41 and rotated. The third clamping bolt 43 presses the second side connector 42, thereby completing the connection between the connecting steel pipe 3 and the crossbeam 14.

[0054] The second side connector 42 is a U-shaped part, and a connection gap 421 is formed between the two side walls of the second side connector 42. The connecting steel pipe 3 is hinged to the inside of the connection gap 421, and the third clamping bolt 43 is threaded to the inside of the connection gap 421.

[0055] This design, with the second side connector 42 shielding it, is used to increase the connection stability of the third clamping bolt 43.

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

[0057] This design allows for large-area contact with the connecting steel pipe 3 when the pipe connecting bracket 24 is used to fix the steel pipe 3, thereby improving the connection stability of the pipe connecting bracket 24. By setting both the first clamping rod bracket 21 and the second clamping rod bracket 41 to be U-shaped, large-area contact with the column 11 and the crossbeam 14 is achieved when the first clamping rod bracket 21 and the second clamping rod bracket 41 clamp the column 11 and the crossbeam 14, thereby improving the connection stability of the first clamping rod bracket 21 and the second clamping rod bracket 41.

[0058] like Figure 2 As shown, in a preferred embodiment, it further includes a sliding sleeve 51, an elastic pressure plate 52, and a clamping rod 53. The sliding sleeve 51 is sleeved on the crossbeam 14, and the second clamping rod bracket 41 is sleeved on the sliding sleeve 51. The elastic pressure plate 52 is disposed on the sliding sleeve 51, and the clamping rod 53 is rotatably disposed on the sliding sleeve 51. When the clamping rod 53 rotates, the clamping rod 53 presses the elastic pressure plate 52 toward the side closer to the crossbeam 14.

[0059] By setting the second clamping rod bracket 41 to be sleeved on the sliding sleeve 51, when it is necessary to adjust the crossbeam 14 to move along the connecting beam 13 for fine adjustment, it is not necessary to adjust the connection state of the first crossbeam connector 4. Simply pry the clamping rod 53 so that it rotates out of the elastic pressure plate 52, and the elastic pressure plate 52 releases the crossbeam 14, allowing the crossbeam 14 to move along the sliding sleeve 51. This makes it convenient to adjust the crossbeam 14 to move along the connecting beam 13 for fine adjustment after the first crossbeam connector 4 is connected, making it convenient to use.

[0060] A control lever 54 is provided on the clamping rod 53.

[0061] This design makes it easy to adjust the rotation of the clamping rod 53.

[0062] like Figures 4-5 As shown, in a preferred embodiment, the connecting beam 13 is connected to the crossbeam 14 via the second crossbeam connector 6. The second crossbeam connector 6 includes a third clamping rod 61, a connecting piece 62, a limiting stop 63, and a fourth clamping bolt 64. The connecting beam 13 includes two side beams 131, and the side beams 131 are provided with connecting holes 1311. The third clamping rod 61 is sleeved on the crossbeam 14 and passes through the connecting piece 62, which passes through the two connecting holes 1311. The limiting stop 63 is provided on the connecting piece 62 to prevent the connecting piece 62 from detaching from the side beam 131. The fourth clamping bolt 64 is threadedly connected to the third clamping rod 61 to compress the connecting piece 62.

[0063] It should be noted that in the prior art, the connection method between the connecting beam 13 and the crossbeam 14 is as follows: the crossbeam 14 is to be connected with the two side beams 131. 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 plate is connected to the crossbeam 14 with two U-shaped bolts facing outward, and the flange is connected to the two side beams 131 with four bolts.

[0064] By setting a third clamping rod 61 and connecting it to the connecting beam 13 via a connecting piece 62, when connecting the crossbeam 14 and the connecting beam 13, only the fourth clamping bolt 64 needs to be rotated to connect the crossbeam 14 to the two side beams 131. Compared with the existing method of connecting the crossbeam 14 with two U-bolts and connecting the flange to the two side beams 131 with four bolts, the second crossbeam connector 6 of this application can reduce the complexity of the connection and reduce costs.

[0065] like Figure 6 As shown, in a preferred embodiment, the crossbeam 14 is connected to the mounting beam 15 via a third crossbeam connector 7. The third crossbeam connector 7 includes a fourth clamping rod 71, a third side connector 72, and a fifth clamping bolt 73. The fourth clamping rod 71 passes through the mounting beam 15 and the third side connector 72 and is sleeved on the periphery of the crossbeam 14. The mounting beam 15 and the third side connector 72 are located on opposite sides of the crossbeam 14. The fifth clamping bolt 73 is threaded onto the fourth clamping rod 71 and is used to press the third side connector 72 toward the side closer to the crossbeam 14. A connecting groove 151 is provided on the mounting beam 15, and the fourth clamping rod 71 is located inside the connecting groove 151.

[0066] In practice, the mounting beam 15 is used to connect the external photovoltaic module support. The mounting beam 15 is connected to the photovoltaic module support by bolts, and the photovoltaic module support is arrayed on the mounting beam 15.

[0067] In practice, the fourth clamping rod 71 passes through the inside of the connecting groove 151 and is fitted onto the outside of the crossbeam 14. The third side connector 72 passes through the fourth clamping rod 71, and the fifth clamping bolt 73 is threaded onto the fourth clamping rod 71. By squeezing the third side connector 72, the connection between the crossbeam 14 and the mounting beam 15 is completed.

[0068] By setting the fourth clamping rod 71 inside the connecting groove 151, the connection stability of the fourth clamping rod 71 can be increased under the obstruction of the groove wall of the connecting groove 151.

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

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

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

[0072] Step 3: Rotate the first clamping bolt 23 and the second clamping bolt 25. At this time, the first clamping bolt 23 fixes the position of the first clamping rod 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 rods in this application are all U-shaped rods, and the fifth clamping bolt 73 is connected to the inner side of the third side connector 72.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
