Description

[0002] With the increasing demand for clean energy development in China and the gradual progress of the semiconductor industry, the cost of high-efficiency photovoltaic modules has been falling, making the development of large-scale solar photovoltaic power stations possible. In addition, as the installed capacity of photovoltaic power stations continues to increase, land resources with good light resources and flat terrain are becoming increasingly scarce, and land with complex terrain such as mountains and hills is becoming the main site for the construction of photovoltaic power stations.

[0003] In photovoltaic systems, the main beam is connected mainly through rigid forms such as clamps, sleeves, and shrink tubes.

For uneven and undulating terrain, the commonly used solutions are mainly to flatten the slope, cut the entire field, or increase the depth of the column before setting up the tracking bracket. However, these two solutions have poor adaptability to different terrains and high adaptation costs.

[0040] In an optional embodiment, if Figures 1-2 As shown, the connecting member 221 has a central axis, and each adjustment through hole 222 is symmetrically arranged with the central axis as the symmetry axis. In this embodiment, by symmetrically arranging each adjustment through hole 222 with the central axis as the symmetry axis, during the process of installing the bearing seat 1 to the connecting member 221, its mounting rod 11 can pass through two adjustment through holes 222 symmetrically with the central axis as the symmetry axis, so as to achieve the installation of the bearing seat 1 on the connecting member 221.

[0041] In an optional embodiment, if Figures 1-2 As shown, the adjustment through hole 222 includes terrain adjustment holes 2221 , and the terrain adjustment holes 2221 are distributed along the circumference of the connecting member 221 .

[0042] In this embodiment, the terrain adjustment holes 2221 are distributed along the circumferential direction of the connecting member 221, that is, each terrain adjustment hole 2221 is distributed around the central axis of the connecting member 221, so that the bearing seat 1 can be installed on the connecting member 221 around the central axis of the connecting member 221, thereby realizing that the bearing seat 1 can adapt to terrain of any slope.

[0043] In an optional embodiment, if Figures 1-2 As shown, the adjustment through hole 222 includes installation adjustment holes 2222 , and the installation adjustment holes 2222 are distributed along the length direction of the connecting member 221 .

[0044] In this embodiment, the installation adjustment holes 2222 are distributed along the length direction of the connecting member 221, that is, each installation adjustment hole 2222 is distributed on the connecting member 221 along the central axis direction of the connecting member 221, so that the bearing seat 1 can be fine-tuned in the length direction of the connecting member 221.

[0045] In an optional embodiment, if Figures 1-2 As shown, a number of adjustment through holes 222 are evenly arranged on the connecting member 221 .

[0046] In this embodiment, by evenly arranging a number of adjustment through holes 222 along the circumferential direction of the connecting member 221 so that the center line angle between every two adjacent adjustment through holes 222 in the circumferential direction of the connecting member 221 is fixed, the installation position of the bearing seat 1 on the connecting member 221 can be adjusted more evenly, and the rotation angle range of the bearing seat 1 on the connecting member 221 can be increased, thereby realizing the adjustment of any slope of the photovoltaic device.

[0047] In an optional embodiment, if Figure 1 , 3 As shown, the connection assembly 22 further includes a locking member 223 , and a locking hole 111 is provided at one end of the mounting rod 11 away from the bearing seat 1 , and the locking member 223 is located in the locking hole 111 .

[0048] In this embodiment, the locking member 223 is a locking pin. When the bearing seat 1 is installed, it is only necessary to insert the mounting rod 11 into the adjustment through hole 222, and finally, the mounting rod 11 extends out of the connecting member 221. The end of the mounting rod 11 extending out of the connecting member 221 has a locking hole 111. At this time, the locking member 223 can be inserted into the locking hole 111, and the bearing seat 1 can be stably installed on the connecting member 221.

[0049] In an optional embodiment, if Figure 2 As shown, the thickness of the connecting member 221 is greater than or equal to 4 mm.

[0050] In this embodiment, since the connecting member 221 is designed as a cylindrical structure with a hollow structure, when the thickness of the cylinder is greater than or equal to 4 mm, the load-bearing capacity of the connecting member 221 can be further improved.

[0052] In this embodiment, by designing the support member 21 as a combination of the first support rod 211 and the second support rod 212, on the one hand, there is a clearance space between the first support rod 211 and the second support rod 212, so that the bearing seat 1 can be rotated into the clearance space, and the rotation range of the bearing seat 1 on the connecting member 221 is further improved; on the other hand, the connecting member 221 is fixed to the ground by the first support rod 211 and the second support rod 212, and the fixing stability is high, and the load-bearing capacity of the connecting member 221 is also improved, thereby indirectly improving the stability of the main beam 3 installed on the bearing seat 1;

[0053] In addition, the first support member 21 and the second support member 21 are both integrally formed on the connecting member 221. Therefore, the connecting member 221 and the entire support member 21 are integrally formed, which effectively reduces the construction procedures and construction costs during the installation process, thereby improving the installation efficiency.

[0054] In an optional embodiment, if Figure 2As shown, the distance between the ends of the first support rod 211 and the second support rod 212 away from the connecting member 221 is greater than the distance between the ends of the first support rod 211 and the second support rod 212 close to the connecting member 221, so that the first support rod 211 and the second support rod 212 gradually approach each other from bottom to top.

[0055] In this embodiment, since the ends of the first support rod 211 and the second support rod 212 near the connecting member 221 are arranged close to each other, the angle between the first support rod 211 and the second support rod 212 and the ground in the opposite direction is less than 90°, and the first support rod 211 and the second support rod 212 are not parallel to each other, thereby further improving the stability of the installation of the photovoltaic device.

[0056] As a second aspect of the present invention, a photovoltaic tracking bracket is provided, which includes a main beam 3 and multiple photovoltaic devices provided in the embodiments of the present application. The main beam 3 is rotatably connected to the bearing seats 1 of the multiple photovoltaic devices, and the main beam 3 is used to fix the photovoltaic panels.

[0057] In this embodiment, in the photovoltaic tracking bracket, the connector 221 of the photovoltaic device is a cylindrical structure, and the connector 221 has a central axis. The connector 221 has a number of adjustment through holes 222, and each adjustment hole has a symmetrical adjustment through hole 222 with the central axis as the axis of symmetry. The number of adjustment holes includes terrain adjustment holes 2221 and installation adjustment holes 2222, and each adjustment through hole 222 is evenly distributed on the connector 221 around the central axis of the connector 221, and each installation adjustment hole 2222 is evenly distributed on the connector 221 along the central axis direction of the connector 221.

[0058] The photovoltaic device's bearing seat 1 has an integrally formed mounting rod 11 on the side facing the connector 221 , and the end of the mounting rod 11 away from the bearing seat 1 passes through two symmetrical adjustment holes 222 , and then the locking piece 223 is inserted into the locking hole 111 to ensure that the bearing seat 1 is stably mounted on the connector 221 .

[0059] In the face of complex terrain with different slopes, the bearing seat 1 can be installed and fixed in sequence around the circumferential direction of the connecting piece 221 through the mounting rod 11, so that the entire photovoltaic tracking bracket can adapt to terrain with any slope. In addition, the bearing seat 1 can also be installed in sequence into the mounting adjustment hole 2222 along the central axis direction of the connecting piece 221 through the mounting rod 11, so as to achieve fine adjustment of the installation position of the bearing seat 1 in the length direction of the connecting piece 221, thereby increasing the slope adaptability of the entire photovoltaic tracking bracket, reducing the construction cost and structural cost of the photovoltaic tracking bracket, and ensuring the economic benefits of the photovoltaic industry.

[0060] The difference from the above embodiment is that, in this embodiment, the locking member 223 is a locking nut, the mounting rod 11 has an external thread, and the locking nut is threadedly connected to an end of the mounting rod 11 away from the bearing seat 1.

[0061] In this embodiment, when installing the bearing seat 1, it is only necessary to insert the mounting rod 11 into the adjusting hole 222, and then screw the locking nut on the end of the mounting rod 11 away from the bearing seat 1, so that the bearing seat 1 can be stably installed on the connecting member 221. The installation method is simple and stable, and the installation efficiency of the bearing seat 1 is effectively improved.

[0062] The difference from the above embodiment is that a buffer pad is provided on the side of the bearing seat 1 facing the connecting member 221. The buffer pad is made of silicone material. On the one hand, the buffer pad can buffer the force of the bearing seat 1 with the main beam 3 being installed on the connecting member 221, thereby increasing the service life of the connecting member 221; on the other hand, it can also increase the friction between the bearing seat 1 and the connecting member 221, thereby improving the stability of the bearing seat 1 installed on the connecting member 221.

[0063] The difference from the above embodiment is that the connecting member 221 is a polygonal column structure.

[0064] The difference from the above embodiment is that the support member 21 is a "Y" shaped structure. During the installation process of the support member 21 with this structure, only the end away from the bearing seat 1 needs to be placed in the soil by sinking a pipe or tamping hammer, which makes the installation more convenient and quick.
