Description

Technical Field

[0001] This utility model relates to the field of photovoltaic tracking brackets, and in particular to a photovoltaic tracking bracket terrain adaptation device. Background Technology

[0002] In the current technology, as the installed capacity of photovoltaic power plants continues to increase, land resources with good solar energy conditions and flat terrain are becoming increasingly scarce. Correspondingly, land with complex terrain such as mountains and hills is becoming the main site for the construction of photovoltaic power plants.

[0003] However, current single-axis tracking systems mainly use rigid connections such as clamps, sleeves, and shrink tubes for spindle connection. Their spindle axes can only be in a straight line, making them suitable only for some flat and relatively flat sites.

[0004] Figure 1 This is a schematic diagram of installation on undulating terrain in existing technology. For example... Figure 1 As shown, existing solutions for undulating terrain mainly include two aspects: one is to level and cut the site; the other is to increase the driving depth of the posts. However, both of these solutions will significantly reduce the overall economic performance of the project.

[0005] Furthermore, existing tracking supports adapted to undulating terrain typically employ omnidirectional devices, which present the following main technical problems:

[0006] First, while universal joints can adapt to different terrains, their placement between two columns allows them to transmit torque but not bending moments, and there is a risk of them jamming.

[0007] Second, single-row supports cannot adapt to complex terrain.

[0008] Third, while using universal joints to adapt to terrain, the cross-shaped universal joint structure has low transmission efficiency and is at risk of jamming.

[0009] In view of this, the inventors of this application have designed a photovoltaic tracking bracket terrain adaptation device in order to overcome the above-mentioned technical problems. Utility Model Content

Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts.

[0045] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0046] Furthermore, it is required that this utility model be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0047] Example 1:

[0048] like Figure 2 and Figure 3 As shown, this utility model discloses a photovoltaic tracking bracket terrain adaptation device, which includes at least two main beams 10, a first connector 20, a second connector 30, at least one column 40, and at least two support seats 50. The first connector 20 is installed at the end of one of the main beams 10, and the second connector 30 is installed at the end of the adjacent main beam 10. A protrusion 21 is provided on the end face of the first connector 20, and a groove 31 is provided on the end face of the second connector 30. The protrusion 21 and the groove 31 are connected by an arc surface and can rotate relative to each other along the arc surface.

[0049] Each pair of support bases 50 is fixed to the top of the column 40, and the first connector 20 and the second connector 30 are rotatably installed in the corresponding support base 50.

[0050] Of course, this is just an example of the connection and installation structure of two adjacent main beams 10. In fact, the photovoltaic tracking bracket terrain adaptation device is composed of many main beams 10 connected in sequence by rotation. Its connection and installation structure is the same as the connection and installation structure of the two adjacent main beams above. Therefore, it will not be described in detail here. Those skilled in the art should know its overall structure.

[0051] like Figures 4 to 7 As shown, the first connector 20 and the second connector 30 are preferably spherical structures, rotating relative to the support base 50 on the spherical surface. The protruding portion 21 of the first connector 20 has an arc-shaped surface, and the inner wall of the grooved portion 31 of the second connector 30 has an arc-shaped inner wall. The protruding portion 21 and the grooved portion 31 rotate relative to each other along the arc surface.

[0052] The end face 22 of the first connector 20 is preferably flat, the protruding portion 21 extends horizontally outward along the end face 22, and the end of the protruding portion 21 is an arc surface. For example Figure 3 and Figure 4As shown, the protrusion 22 is directly disposed on the end face 22 and extends outward. The protrusion 22 can preferably be arranged horizontally or vertically. One end of the first connector 20 is provided with a first connecting groove 23 and a plurality of first connecting holes 24. The first connecting groove 23 is disposed opposite to the end face 22, and the first connecting holes 24 surround the first connecting groove 23. The main beam 10 is installed in the first connecting groove 23 and is fixed in the first connecting groove 23 by fasteners passing through the first connecting holes 24.

[0053] The end face 32 of the second connector 30 is preferably a plane, and the groove portion 31 extends inward along the end face 32 to form an arc-shaped groove. For example Figure 5 and Figure 6 As shown, an arc-shaped groove is formed on the end face 32, creating a groove portion 31 that extends inward. The arc shape of the inner wall of the groove portion 31 matches the annular shape of the outer end face of the protrusion portion 22. One end of the second connector 30 also has a second connecting groove 33 and multiple second connecting holes 34. The second connecting groove 33 is positioned opposite to the end face 32, and the second connecting holes 34 surround the second connecting groove 33. The main beam 10 is installed in the second connecting groove 33 and is fixed in the second connecting groove 33 by fasteners passing through the first connecting holes 24.

[0054] The protruding portion 21 of the first connector 20 can be inserted into the grooved portion of the second connector 30, allowing the two parts to rotate relative to each other along the arc surface, thereby connecting the first connector 20 and the second connector 30 to each other. This structure can transmit torque by inserting the protruding portion 21 of the first connector 20 into the grooved portion 31 of the second connector 30, that is, the main beam 10 at the left end can drive the main beam 10 at the right end to move synchronously, or the main beam 10 at the right end can drive the main beam 10 at the left end to move.

[0055] Preferably, the support base 50 includes an upper seat ring 51 and a lower seat ring 52. The lower seat ring 51 is fixed to the top of the column 40. The first connecting member 20 and the second connecting member 30 are respectively installed on the corresponding lower seat ring 52. The upper seat ring 51 is fastened to the first connecting member 20 and the second connecting member 30 and is fixedly connected to the corresponding lower seat ring 52. The hollow annular inner wall surface formed by the support base 50 matches the outer wall surfaces of the first connecting member 20 and the second connecting member 30 respectively.

[0056] Furthermore, the support base 50 is fixed to the column connector 41, and the column connector 41 is fixed to the top of the column 40. After adjusting the angle according to the terrain, tighten the mounting bolts of the support base 50 and the column connector 41.

[0057] Both the first connector 10 and the second connector 20 can rotate relative to the support base 50 on a spherical surface. In this embodiment, the support base 50 is configured as a split upper and lower structure, which facilitates the installation of the first connector 20 and the second connector 30, and the first connector 20 and the second connector 30 are respectively fixed to the main beams 10 at both ends.

[0058] This structure allows the main beam 10 to rotate spherically relative to the support base 50. Simultaneously, this structure allows for rotation with a certain angular difference between one end of the main beam 10 and the other end, and synchronous rotation, thus accommodating installation on different terrains while also transmitting torque.

[0059] like Figure 8 and Figure 9 As shown, when the photovoltaic tracking bracket terrain adaptation device adapts to different angles of installation, the main beams 10 at both ends of each column 40 are allowed to have a certain angle difference, both in the east-west and north-south directions. This allows the entire row of brackets to adapt to complex terrains, while also greatly reducing the pile driving accuracy requirements of the brackets and reducing the adjustment margin of components, thus bringing certain cost advantages to the brackets.

[0060] In this novel photovoltaic tracking bracket terrain adaptation device, one main beam 10 can drive the other main beam 10 to rotate, satisfying the adaptability to complex terrain while also serving as a torque transmission mechanism. This structure can directly replace the traditional bearing structure without affecting the system layout.

[0061] In summary, this utility model's photovoltaic tracking bracket terrain adaptation device can adapt to undulating terrains such as mountains and hills, significantly reducing project costs and expanding the application scenarios of single-axis systems. Furthermore, the adaptation device does not require the main shaft axis to be in a straight line, reducing the accuracy requirements for pile driving.

[0062] This utility model of a photovoltaic tracking bracket terrain adaptation device can be applied not only to flat terrain but also to undulating terrains such as mountains and hills, without requiring land leveling or increasing the height of the support column. The adaptation device can adapt to undulating terrain, and the bracket is built according to the terrain, meeting the needs of complex terrain applications, which can significantly improve the economic performance of the project and reduce the project development cycle.

[0063] Example 2:

[0064] like Figure 10 and Figure 11As shown, this utility model also provides a photovoltaic tracking bracket terrain adaptation device, which includes at least two main beams 100, a column 200, and at least two bearing assemblies 300. One main beam 100 has an outwardly protruding protrusion 110 at its end, and the adjacent main beam 100 has an outwardly protruding groove 120 at its end. The groove 120 and the protrusion 110 are connected by an arc surface, allowing the two adjacent main beams 100 to rotate relative to each other along the arc surface. The ends of the main beams 100 are rotatably connected to the column 200 via one of the aforementioned bearing assemblies.

[0065] When the end grooves and end protruding arc surfaces of two adjacent main beams 100 are engaged, they can not only rotate relative to each other, but also transmit torque. That is, the main beam 100 at the left end can drive the main beam 100 at the right end to move synchronously, or the main beam 100 at the right end can drive the main beam 100 at the left end to move.

[0066] Of course, this is just an example of the connection and installation structure of two adjacent main beams 100. In fact, the photovoltaic tracking bracket terrain adaptation device is composed of many main beams 100 connected in sequence by rotation. Its connection and installation structure is the same as the connection and installation structure of the two adjacent main beams above. Therefore, it will not be described in detail here. Those skilled in the art should know its overall structure.

[0067] like Figures 12 to 14 As shown, a connecting plate 130 is provided at the end of one of the main beams 100, and a protruding portion 110 is fixed to the connecting plate 130 and extends outward. The outer end face of the protruding portion 110 is an arc surface, which can preferably be arranged horizontally or vertically.

[0068] Correspondingly, a connecting plate 140 is provided at the end of the adjacent main beam 100, and the groove portion 120 is fixed on the connecting plate 140 and extends outward. Preferably, two mutually separated columns are provided on the connecting plate 140, and arc-shaped grooves are opened on the opposite surfaces of the two columns, so that a circular groove, i.e., the groove portion 120, is formed between the columns.

[0069] The groove portion 120 and the protrusion portion 110 are shaped to match each other, and the protrusion portion 110 can rotate within the groove portion 120. Of course, this is only an example, and other rotating connections can also be used, all of which are within the protection scope of this application.

[0070] This structure can transmit torque by inserting the protrusion 110 into the groove 120, that is, the main beam 100 at the left end can drive the main beam 100 at the right end to move synchronously, or the main beam 100 at the right end can drive the main beam 100 at the left end to move.

[0071] Preferably, each bearing assembly 300 includes an upper bearing seat 310, a lower bearing seat 320, and a bearing 330. The bearing 330 is sleeved on the end of the corresponding main beam 100, the lower bearing seat 320 is fixed on the column 200, and the upper bearing seat 310 and the lower bearing seat 320 are fastened together.

[0072] The bearing 330 can be fixed inside the bearing housing and can rotate spherically between the upper part 310 and the lower part 320 of the bearing housing. The hollow annular inner wall surface formed between the upper part 310 and the lower part 320 of the bearing housing matches the outer wall surface of the bearing 330, and the main beam 100 achieves spherical rotation between the lower part 320 and the upper part 310 of the bearing housing through the bearing 330.

[0073] In this embodiment, the bearing housing is designed as a separate upper and lower structure, which facilitates the installation of the bearing 330. The main beam 100 passes through the bearing 330 and can rotate with the bearing 330 within the spherical surface of the bearing housing.

[0074] This structure allows for rotation of one main beam 100 at a certain angle to the other main beam 100, and they can rotate synchronously. This can meet the installation requirements of different terrains and can also transmit torque.

[0075] Furthermore, the lower part 310 of the bearing ring seat is fixed to the column connector 210, and the column connector 210 is fixed to the top of the column 200. After adjusting the angle according to the terrain, tighten the mounting bolts of the lower part 310 of the bearing ring seat and the column connector 210.

[0076] like Figure 15 and Figure 16 As shown, in the terrain adaptation device for photovoltaic tracking brackets of this utility model, the main beams 100 at both ends of each column 200 are allowed to have a certain angle difference, both in the east-west and north-south directions, thus enabling the entire row of brackets to adapt to complex terrains. At the same time, it can also greatly reduce the accuracy requirements for piling and the adjustment margin of components, bringing certain cost advantages to the brackets.

[0077] In the aforementioned photovoltaic tracking bracket terrain adaptation device, one end of the main beam can drive the other end of the main beam to rotate. While meeting the adaptability requirements of complex terrain, it can also play a role in torque transmission. This structure can directly replace the traditional bearing structure without affecting the system layout.

[0078] In summary, this utility model's photovoltaic tracking bracket terrain adaptation device can adapt to undulating terrains such as mountains and hills, significantly reducing project costs and expanding the application scenarios of single-axis systems. Furthermore, the adaptation device does not require the main shaft axis to be in a straight line, reducing the accuracy requirements for pile driving.

[0079] This utility model of a photovoltaic tracking bracket terrain adaptation device can adapt to undulating terrain. The bracket can be built according to the terrain without leveling or cutting the site, or increasing the height of the column, which significantly reduces the project construction cost and the amount of steel used for the column.
