[0067]

[0068] According to the above formula, the number of automated production lines is 2, and the number of transport and installation equipment for a single production line is 20;

[0069] Through this formula, the quantity of each equipment can be accurately calculated so as to accurately match it with the construction period, reduce the overall construction time and improve construction efficiency.

[0070] A photovoltaic bracket is also provided, comprising:

[0071] A plurality of purlins 3, the top of the purlin 3 is used for fixing with the photovoltaic module 1;

[0072] A plurality of oblique beams 4 are located below the purlin 3. The purlin 3 and the oblique beams 4 are fixedly connected by first bolts. The purlin 3 is provided with a plurality of first long waist holes arranged along the length direction of the purlin 3. The first bolts penetrate the first long waist holes.

[0073] Multiple groups of support components are arranged one by one corresponding to multiple inclined beams 4. The support components include two columns 6 located below the inclined beams 4. The tops of the columns 6 are fixedly connected to the inclined beams 4 through second bolts. The inclined beams 4 are provided with multiple second long waist holes 7 arranged along the width direction of the purlins 3. The second bolts penetrate the second long waist holes 7.

[0074] The connecting component is connected to the two columns 6 , and the connecting component is used to connect to the pile foundation 2 .

[0075] A plurality of inclined beams 4 and a plurality of purlins 3 are arranged in a cross-grid pattern, the upright columns 6 are perpendicular to the ground, and the inclined beams 4 are inclined to the ground.

[0076] In some optional embodiments, the connecting assembly includes a plurality of hoops 8 spaced apart vertically, the hoops 8 are fixedly connected to the columns 6, and a cross arm 9 is fixedly connected between the two columns 6 by a third bolt: a third long waist hole is opened on the column 6 along the height direction, the third bolt passes through the third long waist hole, the hoops 8 are sleeved on the pile foundation 2, the cross arm 9 is in contact with the top of the pile foundation 2, and the two columns 6 are respectively in contact with the two opposite outer walls of the pile foundation 2.

[0077] In some optional embodiments, a diagonal brace 10 is rotatably connected to the column 6, and the two columns 6 are located between the two diagonal braces 10. The end of the diagonal brace 10 away from the column 6 is fixedly connected to the diagonal beam 4 by a fourth bolt. The diagonal beam 4 is provided with a plurality of fourth long waist holes 11 arranged along the length direction of the diagonal beam 4. The fourth bolt passes through the fourth long waist hole 11, and the two diagonal braces 10 are respectively connected to the two ends of the diagonal beam 4.

[0078] In some alternative embodiments, according to the actual coordinates of the pile foundation 2, the deviation amounts of multiple pile foundations 2 connected to the photovoltaic support are obtained, so as to adjust the installation position diagrams of the inclined beam 4 and the purlin 3, the inclined beam 4 and the column 6, the inclined beam 4 and the bracing 10, and the column 6 and the cross arm 9 in the photovoltaic support. The left-right deviation of the pile foundation 2 is adjusted by connecting the first bolt to different positions on the first long waist hole, and the front-back deviation of the pile foundation 2 is adjusted by connecting the second bolt and the fourth bolt to different positions on the second long waist hole 7 and the fourth long waist hole 11 respectively; the height deviation of the pile foundation 2 is adjusted by connecting the third bolt to different positions on the third long waist hole.

[0079] In this embodiment, one photovoltaic module 1 corresponds to two pile foundations 2 to improve the support stability. Therefore, two inclined beams 4 are provided. Since there is a deviation between the actual position and the predetermined position of the pile foundation 2, if the assembly position of the hoop 8 is not adjusted, after being transported to the site, the hoop 8 and the pile foundation 2 will be misaligned and the installation cannot be achieved. Therefore, the adjustment is made according to the actual position of the pile foundation during prefabrication. Among them, the first bolt is connected to different positions on the first long waist hole to realize the left-right position adjustment of the hoop 8, and the second bolt is connected to different positions on the second long waist hole 7 to realize the front-back position adjustment of the hoop 8, so as to connect the fourth bolt to different positions on the fourth long waist hole 11 for installation; the third bolt is connected to different positions on the third long waist hole to adjust the height of the cross arm 9. Therefore, when installed on the two pile foundations 2, the cross arm 9 can always contact the top of the pile foundation 2 to achieve stable support.

[0080] In some alternative embodiments, the transportation and installation equipment includes a flatbed truck 12. Multiple support bases are arranged on the flatbed truck 12. The support bases are arranged in multiple layers on the flatbed truck 12. One support base corresponds to one assembled finished product. The support base includes multiple U-shaped frames 13 with openings facing downwards, and the U-shaped frames 13 support the bottoms of multiple purlins 3. The U-shaped frames 13 between layers are detachably connected.

[0081] In some alternative embodiments, two inclined rods 14 in a shape of an inverted V are fixedly connected between the two vertical rods of the U-shaped frame 13. One of the inclined rods 14 on one of the U-shaped frames 13 in the same group of support bases is close to one side of the two columns 6 in any support assembly under the corresponding photovoltaic module 1, and one of the U-shaped frames 13 in the same group of support bases is close to the other side of the two columns 6 in any support assembly under the corresponding photovoltaic module 1. Two limit plates are fixedly connected to the top of the U-shaped frame 13, and the two limit plates are respectively close to the outer side walls of the two purlins 3 at the ends.

[0082] By making the diagonal rods 14 on the two U-shaped frames 13 respectively close to the opposite sides of the two columns 6 in the two groups of support components, the left and right limits of the photovoltaic module 1 are realized. The limiting plates are respectively close to the outer side walls of the two purlins 3 located at the ends to realize the front and rear limits of the photovoltaic module 1. A shock-absorbing layer is provided on the surface where the U-shaped frame 13 contacts the purlin 3 to reduce the vibration of the photovoltaic module 1. Since the position of the purlin 3 does not adjust during assembly, the position of the limiting plate is fixedly set to achieve the precise accuracy of the purlin 3 and improve the limiting accuracy.

[0083] By arranging the two diagonal rods 14 in a V-shaped configuration, they can be close to the column 6 and the diagonal brace 10 without interfering with the hoop 8.

[0084] In some alternative embodiments, in step S6, a forklift 15 is used to install the assembled finished product. A plurality of fork teeth 16 are fixedly connected to the output end of the forklift 15. The forklift 15 drives the fork teeth 16 to move up and down, back and forth, and rotate. A plurality of limiting blocks are fixedly connected to the fork teeth 16, and limiting grooves 17 are formed in the limiting blocks. The plurality of limiting grooves 17 are arranged in one-to-one correspondence with the plurality of purlins 3. When the forklift 15 forks up the photovoltaic support, the fork teeth 16 are perpendicular to the purlin 3, and the purlin 3 is located in the limiting groove 17.

[0085] Since the positions of the purlins 3 in each assembled finished product are consistent, when the forklift 15 forks the finished product, the purlins 3 can accurately fall into the limiting grooves 17 for limiting to prevent dropping during the installation process. The alignment and angle adjustment of the photovoltaic installation finished product are controlled by the fork teeth 16 of the forklift 15. After alignment and placement in place, the on-site installation workers then carry out the connection work between the photovoltaic installation unit and the lower support structure.
