[0002] The solar photovoltaic power generation application market has developed rapidly in recent years, with a wide range of application scenarios and diversity. It has become an industry trend in the energy field and is gradually becoming an ideal green energy source. In order to improve the photovoltaic power generation efficiency of large-scale photovoltaic power stations, tracking brackets are usually used to drive the solar power generation components to rotate and increase the projection area of ​​sunlight on the components.

[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0045] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited to the embodiments described herein.

[0046] In order to solve the above technical problems, as one aspect of the present application, a photovoltaic support device is provided, such as Figures 1 to 11 As shown, the photovoltaic support device includes: a mounting seat 1, a fixing member 2, a coupling 3, a first connecting member 4 and a second connecting member 5.

[0047] The structures and matching relationships of the mounting base 1, the fixing member 2, the coupling 3, the first connecting member 4 and the second connecting member 5 are described below.

[0048] The mounting seat 1 has a mounting portion 11 and a receiving portion 12 provided on the mounting portion 11, and the receiving portion 12 has a through receiving cavity 121. Among them, the mounting portion 11 is used to be mounted on the column connector 71, and the mounting portion 11 and the receiving portion 12 can be integrally formed. The fixing member 2 has a through fixing hole 21, and the fixing member 2 is installed in the receiving cavity 121. In the embodiment of the present application, the fixing member 2 is fixedly installed in the receiving cavity 121, that is, the fixing member 2 and the receiving portion 12 are relatively fixed. The coupling 3 is inserted into the fixing hole 21 and is rotatably connected to the fixing member 2. The first connecting member 4 is connected to one end of the coupling 3, and the second connecting member 5 is connected to the other end of the coupling 3. Among them, the first connecting member 4 and the second connecting member 5 are universally rotated relative to each other. The end of the first connecting member 4 away from the coupling 3 is connected to the main beam connecting member 6, and the end of the second connecting member 5 away from the coupling 3 is connected to another main beam connecting member 6. The two main beam connecting members 6 are respectively connected to the two main beams, that is, one main beam connecting member 6 is connected to one main beam. The main beams on both sides of the mounting base 1 can respectively realize universal rotation relative to the mounting base 1 to adapt to uneven terrain.

[0049] In this embodiment, through the cooperation and relative movement between the coupling 3 and the fixing part 2, the adjacent main beams on both sides of the photovoltaic support device can rotate relative to each other, and each main beam can rotate universally around the mounting seat 1, so that the angle of each main beam can be adjusted to adapt to undulating terrain such as mountains and hills. There is no need to level, cut or adjust the length of the column 7 driven into the ground, which significantly reduces the cost and broadens the application scenarios of the flat single-axis system. There is no need to require the main shaft axis to be in a straight line, which reduces the pile driving accuracy requirements. In addition, the fixing part 2 and the mounting seat 1 of the embodiment of the present application are simple to produce and manufacture, easy and quick to install, and convenient for later maintenance.

[0050] In an alternative embodiment, reference Figure 2 and Figure 3 The fixing member 2 includes a first fixing arc 22 and a second fixing arc 23, and the first fixing arc 22 and the second fixing arc 23 enclose a fixing hole 21. In the embodiment of the present application, the first fixing arc 22 and the second fixing arc 23 are both designed as semi-annular structures, and the two ends of the first fixing arc 22 can abut against the two ends of the second fixing arc 23 respectively, so that the first fixing arc 22 and the second fixing arc 23 enclose the fixing hole 21 facing each other.

[0051] In this embodiment, the fixing member 2 is composed of two semi-annular structures, the first fixing arc 22 and the second fixing arc 23, and the coupling 3 can be installed in the fixing hole 21 more conveniently and quickly; and the semi-annular structure of the first fixing arc 22 and the second fixing arc 23 is also relatively simple to produce and easy to maintain. In addition, the first fixing arc 22 and the second fixing arc 23 enclose the coupling 3, which can reduce the entry of rainwater into the coupling 3 and reduce the erosion of the coupling 3 by rainwater.

[0052] In an alternative embodiment, reference Figure 2 and Figure 4 The coupling 3 has an adjusting portion 31, a first end face 32, a second end face 33, a first shaft 34 and a second shaft 35. The first end face 32 is connected to the adjusting portion 31 via the first shaft 34, and the second end face 33 is connected to the adjusting portion 31 via the second shaft 35. Both the first shaft 34 and the second shaft 35 are universal shafts. The adjusting portion 31 is rotatably arranged in the fixing hole 21, the first end face 32 is connected to the first connecting member 4, and the second end face 33 is connected to the second connecting member 5.

[0053] In this embodiment, since the first shaft 34 and the second shaft 35 are both universal shafts, the first end face 32 and the second end face 33 are universally rotated around the adjustment part 31 through the first shaft 34 and the second shaft 35, respectively. In this way, the main beams on both sides of the photovoltaic bracket device can be universally rotated around the adjustment part 31.

[0054] In an alternative embodiment, reference Figure 3 and Figure 4The surface of the adjusting portion 31 has an outer spherical surface, and the first fixed arc 22 and the second fixed arc 23 have inner spherical surfaces on the opposite sides thereof; wherein the outer spherical surface and the inner spherical surface can rotate relative to each other.

[0055] In this embodiment, when the adjusting part 31 of the coupling 3 rotates in the fixing hole 21, the outer spherical surface of the outer surface of the adjusting part 31 will come into surface contact with the inner spherical surface in the fixing hole 21, and the friction between the two is extremely low, which can reduce the wear between the coupling 3 and the fixing part 2, thereby effectively improving the service life of the fixing part 2 and the coupling 3.

[0056] In an alternative embodiment, reference Figure 2 and Figure 5 , the inner wall for forming the accommodating cavity 121 is provided with a first limiting groove 122 and a second limiting groove 128. The number and position of the first limiting groove 122 and the second limiting groove 128 are not limited. In the embodiment of the present application, the first limiting groove 122 and the second limiting groove 128 are correspondingly arranged on the accommodating portion 12. The number and setting position of the first limiting groove 122 and the second limiting groove 128 can be selected according to actual needs. Figure 3 and Figure 5 The first fixed arc 22 has a first boss 221 (extending in the circumferential direction) disposed on its outer circumference, and the second fixed arc 23 has a second boss 231 (extending in the circumferential direction) disposed on its outer circumference. The first boss 221 and the second boss 231 are respectively inserted into the first limiting groove 122 and the second limiting groove 128, and abut against the side surfaces of the accommodating portion 12 (i.e., the opening surfaces on both sides of the accommodating portion). The fixing member 2 is installed in the accommodating cavity 121 through the locking member 13.

[0057] In this embodiment, after the first fixed arc 22 and the second fixed arc 23 of the fixing member 2 are installed on the coupling 3, the first boss 221 is aligned with the first limiting groove 122 on the accommodating portion 12, and the second boss 231 is aligned with the second limiting groove 128 on the accommodating portion 12, so that the fixing member 2 carrying the coupling 3 is inserted into the accommodating cavity 121. After the insertion is completed, the fixing member 2 is then rotated so that the first boss 221 and the second boss 231 are respectively misaligned with the first limiting groove 122 and the second limiting groove 128, and then the fixing member 2 and the accommodating portion 12 are locked by the locking member 13, so that the fixing member 2 and the accommodating portion 12 are relatively fixedly connected. After the fixing member 2 is installed in the accommodating cavity 121, at this time, the side walls of the accommodating portion 12 are respectively abutted against the two oppositely arranged first bosses 221 and second bosses 231, so that the first boss 221 and the second boss 231 play an axial limiting role on the accommodating portion 12.

[0058] In an optional embodiment, the fixing member 2 is installed in the accommodating cavity 121 through the locking member 13, the first fixing arc 22 and the second fixing arc 23 are provided with a locking hole 24, and the accommodating portion 12 is provided with a connecting hole 123, and in the installed state, the connecting hole 123 is coaxially arranged with the locking hole 24. In the embodiment of the present application, the number of the locking holes 24 is two, one of which is located between the two first bosses 221, and the other is located between the two second bosses 231. It should be noted that the number and position of the locking holes 24 and the connecting holes 123 are not limited, but when the first boss 221 and the first limiting groove 122 are misaligned and the second boss 231 and the second limiting groove 128 are misaligned, the locking hole 24 and the connecting hole 123 need to correspond to each other, so that the locking member 13 is penetrated in the connecting hole 123 and the locking hole 24, thereby locking the fixing member 2 and the accommodating portion 12. In addition, in order to increase the installation speed of the fixing member 2 and the accommodating portion 12 , the radius of the locking hole 24 is greater than or equal to the radius of the connecting hole 123 , so that the locking member 13 can be inserted into the locking hole 24 more conveniently and quickly.

[0059] The difference from the above embodiment is that, Figures 6 to 9 As shown, the fixing member 2 of the photovoltaic bracket device is rotatably arranged in the accommodating cavity 121, that is, the fixing member 2 and the accommodating portion 12 can rotate relative to each other. The fixing member 2 includes a first support shell 25 and a second support shell 26, and the first support shell 25 and the second support shell 26 are detachably connected. In the embodiment of the present application, the inner surface of the end of the first support shell 25 facing the second support shell 26 is provided with an internal thread, and the outer surface of the end of the second support shell 26 facing the first support shell 25 is provided with an external thread, and the first support shell 25 and the second support shell 26 are fastened by threaded connection. The first support shell 25 has a first support hole 251 that penetrates therethrough, and the second support shell 26 has a second support hole 261 that penetrates therethrough, and the first support hole 251 and the second support hole 261 are connected to form a fixing hole 21. When the adjusting portion 31 of the coupling 3 is installed in the fixing hole 21, the second end face 33 is located in the second supporting hole 261 of the second supporting shell 26, while the first end face 32 is located outside the first supporting hole 251 away from the second supporting hole 261. It can be seen that most of the entire coupling 3 is in the fixing member 2.

[0060] In this embodiment, the fixing member 2 is composed of a first supporting shell 25 and a second supporting shell 26, which facilitates the installation of the coupling 3 in the fixing member 2; in addition, the adjusting portion 31 and the second end face 33 of the coupling 3 are located in the fixing member 2, and can rotate along the spherical surface of the fixing member 2 in the fixing hole 21, and the entire fixing member 2 is rotatably installed on the accommodating portion 12. Therefore, during the rotation of the coupling 3, the fixing member 2 and the coupling 3 jointly bear the radial force caused by the shear force, that is, the fixing member 2 can share the radial force of the coupling 3, which improves the reliability of the overall structure and reduces the strength requirements of the coupling 3. At the same time, the fixing member 2 also plays a certain sealing role on the coupling 3, effectively reducing the impact of rain and dust on the coupling 3.

[0061] In an optional embodiment, the mounting portion 11 includes a first mounting portion 111 and a second mounting portion 112, the first mounting portion 111 is provided with a first accommodating portion 124, and the first mounting portion 111 and the first accommodating portion 124 can be integrally formed; the second mounting portion 112 is provided with a second accommodating portion 125, and the second mounting portion 112 and the second accommodating portion 125 are integrally formed; the first accommodating portion 124 has a first accommodating hole 1241 that penetrates, the second accommodating portion 125 has a second accommodating hole 1251 that penetrates, and the first accommodating hole 1241 and the second accommodating hole 1251 are connected to form an accommodating cavity 121. In the embodiment of the present application, the mounting seat 1 adopts a two-part structural design to facilitate the installation of the fixing member 2 in the accommodating cavity 121.

[0062] The difference from the above embodiment is that, Figure 2 and Fig.10 As shown, the accommodating portion 12 includes a clamping half ring 126 and an accommodating seat 127. The accommodating seat 127 is integrally formed with the mounting portion 11. One end of the clamping half ring 126 is hingedly arranged on the accommodating seat 127, and the other end is clamped with the accommodating seat 127, and an accommodating cavity 121 is formed between the clamping half ring 126 and the accommodating seat 127. When the coupling 3 needs to be installed on the mounting seat 1, it is only necessary to open the clamping structure between the clamping half ring 126 and the accommodating seat 127, and then put the coupling 3 into the accommodating seat 127, and then clamp the clamping half ring 126 onto the accommodating seat 127 again, and the coupling 3 can rotate relative to the accommodating portion 12 in the accommodating cavity 121.
