[0030] Please refer to Figures 1 to 7 As shown, this utility model discloses a connection structure between a photovoltaic column and a main beam, which includes a column top seat 1, a bearing seat 2, and a transition piece 3 disposed between the column top seat 1 and the bearing seat 2. The transition piece 3 is fixedly connected to the bearing seat 2 and the column top seat 1. The connection method between the transition piece 3 and the bearing seat 2 and the column top seat 1 can be welding, bolt connection, stud connection, riveting, pin connection, snap-fit, or interference fit, etc., and this application is not limited to these methods.

[0031] Please refer to Figure 6 As shown, the column top base 1 includes a top plate 11, a first side plate 12, and a second side plate 13. The first side plate 12 and the second side plate 13 are vertically connected to both sides of the top plate 11. The top plate 11 is used to connect with the adapter 3 and the bearing seat 2. The main beam passes through the bearing seat 2. The first side plate 12 and the second side plate 13 are used to connect with the photovoltaic column, thereby realizing the connection between the photovoltaic column and the main beam.

[0032] For details, please refer to Figure 2 As shown, the top plate 11 includes a groove 110, which includes a first groove 1101. The bearing seat 2 includes a second groove 220, and the opening of the second groove 220 is opposite to the opening of the first groove 1101. The first groove 1101 and the second groove 220 are used together to accommodate the adapter 3. That is, by setting the groove 110, the top plate 11 is made into a bent structure, which is beneficial to improving the bending resistance of the column top seat. By setting the adapter 3 in the first groove 1101 and the second groove 220, the adapter 3 not only plays a supporting role, but can also be limited and connected to the column top seat 1 and the bearing seat 2 respectively, reducing the mutual movement between the bearing seat 2 and the column top seat 1 in the first direction, and realizing a stable connection between the photovoltaic column and the main beam. It should be noted that the first direction is parallel to the width direction of the top plate 11.

[0033] In some implementation methods, please refer to Figure 4 As shown, the groove depth of the first groove 1101 is h1, and the groove depth of the second groove 220 is h2, where h1 ≥ h2. This is because the wall portion where the second groove 220 is located should not be made too thick, as this would easily lead to an increase in the weight of the bearing housing 2.

[0034] In some embodiments, the connection structure between the photovoltaic column and the main beam further includes a fastening assembly 4. The fastening assembly 4 passes through the bearing housing 2, the adapter 3, and the column top seat 1, fixing the bearing housing 2 and the column top seat 1 together. The fastening assembly 4 passes through the three components, reducing the number of fasteners required when the components are connected in pairs, and strengthening the connection strength between the three. Additionally, it assists in positioning the relative positions of the bearing housing 2, the adapter 3, and the column top seat 1. The fastening assembly 4 can be a bolt, stud, rivet, or pin, etc., and this application is not limited to these.

[0035] In other embodiments, the fastening assembly 4 does not pass through the adapter 3; that is, the bearing housing 2 and the column top seat 1 are directly fastened together by the fastening assembly 4. For example, the fastening assembly 4 includes at least two fastening sub-assemblies located on different sides of the adapter 3. One end of each of the at least two fastening sub-assemblies is connected to the bearing housing 2, and the other end is connected to the column top seat 1, so that the bearing housing 2 and the column top seat 1 clamp the adapter 3. As another example, the fastening assembly 4 is a single piece, surrounding the adapter 3 and enclosing the adapter 3 within the fastening assembly 4.

[0036] Please refer to Figure 2 and Figure 6 As shown, the top plate 11 includes a body portion 110' and a groove portion 110 connected to the body portion 110'. The body portion 110' includes a first surface 111 and a second surface 112, which are located on opposite sides of the thickness direction of the top plate 11. A first groove 1101 is formed recessed from the first surface 111 toward the second surface 112, and the groove portion 110 protrudes from the second surface 112, that is, the groove portion 110 is a U-shaped structure protruding from the second surface 112. The bending resistance of the U-shaped structure is better than that of the straight structure. Therefore, by providing the groove portion 110, the bending resistance of the column top seat can be improved. The first groove 1101 includes a first hole 1102 for the fastening assembly 4 to pass through.

[0037] Please refer to the embodiments illustrated in this utility model. Figure 4 As shown, the top plate 11 includes two grooves 110, which are spaced apart. A portion of the body portion 110' between the two grooves 110 abuts against the bearing seat 2. In other possible embodiments, the top plate 11 may have one or more grooves 110, and the number of grooves 110 may be set as needed according to actual conditions. This application is not limited to this.

[0038] Please refer to Figure 7 As shown, the first side plate 12 has several fifth holes 121, at least one of which is an elongated hole. The second side plate 13 has several sixth holes 131, at least one of which is an elongated hole. The elongated holes of the first side plate 12 and the second side plate 13 are opposite each other. During on-site installation, the pile foundation of the photovoltaic tracking bracket often experiences deviations in height or horizontal direction, and the columns generally use profiles of uniform height. Therefore, the top of the column will have height or horizontal errors. By providing elongated holes in both the first side plate 12 and the second side plate 13, the position of the column top seat 1 in the height or horizontal direction of the photovoltaic column can be adjusted, thereby ensuring that the bearing seats 2 on each column are at the same height or aligned horizontally, facilitating the subsequent installation of the main beam.

[0039] For details, please refer to Figure 7 As shown, the elongated hole of the first side plate 12 extends along the first arc, and the elongated hole of the second side plate 13 extends along the second arc. This allows the position of the column top seat 1 in the horizontal direction of the photovoltaic column to be adjusted, thereby ensuring that the bearing seats 2 on each column are located on the same axis, which facilitates the installation of the main beam.

[0040] Please refer to Figure 6 As shown, both sides of the top plate 11 are provided with a first flange 113, and the height of the first flange 113 protruding from the second surface 112 is equal to the height of the groove 110 protruding from the second surface 112. In this way, the first flange 113 will not interfere with the workers when installing the fastening component 4.

[0041] Please refer to Figure 6 As shown, the bearing housing 2 includes a main body 21 and a base 22, with the base 22 connected to the main body 21. The main body 21 has a bearing cavity 210 for housing the bearing. The base 22 includes a third surface 221 opposite to the first surface 111, and a second groove 220 is recessed in the third surface 221.

[0042] Please refer to Figure 6 As shown, the base 22 has a mounting cavity 222 and a second hole 223. The second hole 223 penetrates the third surface 221 and connects the second groove 220 with the mounting cavity 222. The fastening component 4 passes through the second hole 223, the first hole 1102 and the adapter 3 to lock the column top seat 1, the adapter 3 and the bearing seat 2. The fastening component 4 is partially located in the mounting cavity 222.

[0043] Please refer to the embodiments illustrated in this utility model. Figure 6 As shown, the base 22 has two mounting cavities 222 and two second grooves 220, which are opposite to the two first grooves 1101. The base 22 has a weight reduction hole 224, which is located between the two mounting cavities 222, which is beneficial for reducing the weight of the bearing housing 2.

[0044] Adapter 3 is a pipe fitting, and its cross-section is rectangular. Please refer to... Figure 2 As shown, the adapter 3 includes a first wall portion 31, a second wall portion 32 opposite to the first wall portion 31, a third wall portion 33 connecting one side of the first wall portion 31 and one side of the second wall portion 32, and a fourth wall portion 34 connecting the other side of the first wall portion 31 and the other side of the second wall portion 32. The first wall portion 31 abuts against the bearing seat 2, and the second wall portion 32 abuts against the column top seat 1. The first wall portion 31 is provided with a third hole 310, and the second wall portion 32 is provided with a fourth hole 320. The fastening assembly 4 passes through the third hole 310 and the fourth hole 320.

[0045] Please refer to Figure 6 As shown, the fastening assembly 4 includes a bolt 41 and a nut 42 connected to the bolt 41. During installation, the shank of the bolt 41 passes through the second hole 223, the third hole 310, the fourth hole 320, and the first hole 1102 in sequence and is connected to the nut 42. The head of the bolt 41 is located in the mounting cavity 222.
