[0002] Photovoltaic brackets are an important part of photovoltaic power generation. With the continuous development of photovoltaic projects, the land space that can accommodate traditional brackets is becoming increasingly scarce, and more and more terrains that can be used to deploy photovoltaics have height differences. When installing photovoltaic brackets, the photovoltaic shafts in the same row must be in a straight line so that the photovoltaic components can be rotated synchronously through the rotation of the shafts to adjust the lighting angle. However, the angle adjustment of traditional photovoltaic brackets is limited and is greatly affected by the height difference of the terrain. During installation, it is impossible to eliminate the impact of the height difference of the terrain on the photovoltaic installation, making it difficult for the photovoltaic shaft to be in a straight line, resulting in the need for secondary processing of the photovoltaic bracket on site to meet the terrain requirements.

DETAILED DESCRIPTION

[0015] With respect to the above technical solution, preferred embodiments are now cited and specifically described in conjunction with drawings.

[0016] See also Figure 1 , a photovoltaic support adjustment device for eliminating terrain height difference includes a support mechanism 10 and an adjustment mechanism 20. The support mechanism 10 can be connected and fixed on a base A. The adjustment mechanism 20 is installed on the support mechanism 10 and can adjust the installation height and angle relative to the support mechanism 10.

[0017] Support mechanism 10, see Figure 2, including a bottom plate 101, a support column 102 and a stiffening plate 103. The bottom plate 101 is fixedly connected to the bottom end of the support column 102, and the bottom plate 101 and the support column 102 are fixedly connected by a plurality of stiffening plates 103 to strengthen the connection strength between the bottom plate and the support column. In the upper part of the opposite sides of the support column 102, corresponding fixing holes 104 with uniform spacing and vertical arrangement are opened, and the fixing holes 104 penetrate the opposite sides of the support column. The support column 102 is welded to the bottom plate 101 in the center,

[0018] In this embodiment, the support column 102 is an I-beam, and the stiffening plates 103 are respectively located at the grooves on both sides of the I-beam, and are centrally welded to the grooves of the I-beam. The fixing holes 104 are arranged in two vertical rows, and the spacing of the fixing holes 104 in each row is consistent. The two rows of fixing holes are respectively located in the groove areas on both sides of the I-beam. The support column 102 can also be a square column.

[0019] Adjustment mechanism 20, see Figure 3 , including a U-shaped sleeve component 201, a top plate 202, an inclined beam connecting portion 203, and a reinforcing plate 204; the top plate 202 is centrally fixedly connected to the top end of the U-shaped sleeve component 201, the inclined beam connecting portion 203 is centrally fixedly connected to the top plate 202, and the reinforcing plate is located on the outer sides of the opposite side walls of the U-shaped sleeve component 201, and is fixedly connected to the top plate 202 and the inclined beam connecting portion 203 to strengthen the connection strength between the top plate 202 and the inclined beam connecting portion 203.

[0020] The U-shaped sleeve component 201 has a U-shaped structure in cross section. The U-shaped sleeve component 201 can be sleeved on the outer periphery of the upper part of the support column 102. Vertically arranged fixed connection holes 2011 and limit connection holes 2012 are provided on the opposite side wings of the U-shaped sleeve component 201. The vertical spacing between the fixed connection hole 2011 and the limit connection hole 2012 is twice the spacing between two vertically adjacent fixed holes 104 on the support column. The limit connection hole 2012 is an arc-shaped hole, and the maximum arc α of the limit connection hole 2012 should be determined according to the terrain slope β of the photovoltaic bracket to ensure that α≥β. When the U-shaped sleeve component 201 is sleeved on the outer periphery of the support column 102 and the height and angle are adjusted, the fixed connection hole 2011 and the limit connection hole 2012 correspond to a fixed hole 104 on the support column 102 respectively.

[0021] An inclined beam rotation hole is provided at the upper part of the inclined beam connection part 203 for the photovoltaic installation shaft to pass through. The diameter of the inclined beam rotation hole is determined according to the outer diameter of the photovoltaic installation shaft.

[0022] When installing a photovoltaic support, a pile foundation is generally set on the ground, and the pile foundation can be a concrete pile or a pile foundation of other structures. The bottom plate 101 of the support mechanism 10 is generally connected to the embedded parts on the pile foundation by welding or mechanical connection, and the support column 102 is kept perpendicular to the horizontal line.

[0023] During installation, first install the support mechanism 10 on the pile foundation A, and then sleeve the adjustment mechanism 20 on the support mechanism, that is, the U-shaped sleeve component 201 is sleeved on the support column 102, so that the U-shaped opening side of the U-shaped sleeve component 201 faces the downslope direction of the terrain, and then adjust the relative position of the adjustment mechanism 20 with respect to the support mechanism 10 according to the terrain elevation difference. After adjusting the relative position, pass a bolt through the fixed connection hole 2011 and the corresponding fixing hole 104, and then use the bolt passing through the fixed connection hole 2011 and the fixing hole 104 as the rotating shaft to adjust the angle of the adjustment mechanism 20 relative to the vertical center line of the support mechanism 10, so that the inclined beam rotation hole of the inclined beam connection part and the inclined beam rotation holes on other photovoltaic brackets are located on the same straight line to ensure the installation of the rotating shaft. After adjusting the angle, the limiting connection hole and the corresponding fixing hole 104 are also connected by bolts. Finally, the bolts passing through the fixing connection hole 2011 and the corresponding fixing hole 104, and the bolts passing through the limiting connection hole and the corresponding fixing hole 104 are respectively locked and fixed by nuts.

[0024] If the terrain is relatively flat, there is no requirement for the opening direction of the adjustment mechanism, and the vertical center line of the adjustment mechanism should be kept coincident with the vertical center line of the supporting column.
