[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] See also Figure 1 An embodiment of the present application provides a photovoltaic device, including a photovoltaic panel 10 and a photovoltaic bracket. The photovoltaic panel 10 is installed on the photovoltaic bracket. The photovoltaic panel 10 is used to receive sunlight and convert the sunlight into electrical energy. The photovoltaic bracket is fixed to the ground for erecting the photovoltaic panel 10.

[0034] See also Figure 2 Specifically, the photovoltaic bracket includes a column 1, a fixed structure 2 and a steel strand 3. The number of columns 1 is multiple, and the multiple columns 1 are arranged at intervals. The fixed structure 2 includes a first end plate 21, a second end plate 22 and an anchor plate 23. The first end plate 21 is connected to the top of the column 1, the second end plate 22 is connected to the first end plate 21, and the anchor plate 23 is rotatably connected to the second end plate 22; the steel strand 3 is respectively connected to the column 1 along its extension direction, and the steel strand 3 is connected to the anchor plate 23; wherein the extension direction of the steel strand 3 is set to a first direction L1, the first end plate 21 is inclined relative to the horizontal plane, and its inclination direction is set to a second direction L2, and during the rotation of the steel strand 3 relative to the second end plate 22, the first direction L1 can be selectively parallel to the second direction L2.

[0035] In practical applications, the number of columns 1 can be set along the extension direction of the steel strand 3, and the top of the column 1 is fixed with a first end plate 21 and a second end plate 22, and the second end plate 22 is used to fix the steel strand 3, so that the steel strand 3 can be fixed on the column 1; when the photovoltaic support is set in a mountainous area with uneven terrain, the height of each column 1 is different along the extension direction of the steel strand 3, resulting in the steel strand 3 being inclined relative to the horizontal plane. Therefore, the traditional steel strand 3 and the anchor plate 23 are angled, that is, the steel strand 3 and the anchor plate 23 are not perpendicular, so that the stress at the angle is concentrated, which easily causes the steel wire of the steel strand 3 to break at the angle, thereby affecting the strength and safety of the entire steel strand 3. In addition, the anchor plate 23 can evenly disperse the tension of the steel strand 3 to keep it stable. If the steel strand 3 and the anchor plate 23 are angled, the anchoring effect will be affected, which may lead to loose anchoring.

[0036] Based on this, the present application rotatably connects the anchor plate 23 with the second end plate 22. When the photovoltaic bracket is located in a mountainous area with uneven terrain, the anchor plate 23 can rotate relative to the second end plate 22. The anchor plate 23 drives the steel strand 3 to rotate, so that the steel strand 3 presents an inclined state matching the terrain, and the anchor plate 23 and the steel strand 3 are always in a vertical state, effectively avoiding the formation of an angle between the anchor plate 23 and the steel strand 3.

[0037] At the same time, the first end plate 21 is also tilted relative to the horizontal plane, and its tilting direction is set to the second direction L2. When the anchor plate 23 rotates relative to the second end plate 22, the extension direction of the steel strand 3, that is, the first direction L1, when the anchor plate 23 rotates to a certain angle, the first direction L1 can be parallel to the second direction L2, so that the tilting angle of the steel strand 3 can be increased, and the collision between the steel strand 3 and the first end plate 21 when tilted can be avoided, and the adjustable angle of the steel strand 3 can be increased, thereby enhancing the ability of the photovoltaic bracket to adapt to terrain. Photovoltaic equipment using this photovoltaic bracket can adapt to a variety of terrains and improve the practical range of photovoltaic equipment.

[0038] See again Figure 2 The photovoltaic bracket also includes an anchor 4, the steel strand 3 passes through the anchor plate 23, the anchor 4 is connected to one end of the steel strand 3 extending out of the anchor plate 23, and abuts against the anchor plate 23.

[0039] In actual application, the anchor 4 plays a locking role, fixing the steel strand 3 in a certain position to prevent it from sliding or shifting when subjected to force. At the same time, the anchor 4 abuts against the anchor plate 23. Since the steel strand 3 is usually tensioned before installation, the steel strand 3 will have a certain rebound phenomenon after being stretched. At this time, the steel strand 3 generates a pulling force on the anchor 4, and this pulling force is transmitted to the anchor plate 23 through the anchor 4, so that the anchor plate 23 is pressed against the second end plate 22, thereby strengthening the connection stability between the anchor plate 23 and the second end plate 22 and preventing the anchor plate 23 from detaching from the second end plate 22.

[0040] In one embodiment, see Figure 6 The anchor plate 23 is provided with a rotation groove 231 , and the second end plate 22 is provided with a rotation portion 221 on one side facing the anchor plate 23 . The rotation portion 221 extends into the rotation groove 231 and rotates in cooperation with the rotation groove 231 .

[0041] Specifically, two second end plates 22 are arranged on the first end plate 21, and the anchor plate 23 is located between the two second end plates 22. A rotating portion 221 is connected to the second end plate 22, and the rotating portion 221 extends toward the direction close to the anchor plate 23 and extends into the rotating groove 231 of the anchor plate 23. The function of the anchor plate 23 rotating relative to the second end plate 22 is realized through the rotation cooperation of the rotating groove 231 and the rotating portion 221.

[0042] See also Figure 3 The anchor 4 includes an extrusion piece 41 and a fixing piece 42. The extrusion piece 41 is provided with a first extrusion hole 411, and the steel strand 3 passes through the first extrusion hole 411. The fixing piece 42 is provided with a second extrusion hole 421. The extrusion piece 41 is arranged in the second extrusion hole 421. Along the length direction of the steel strand 3, the diameter of the second extrusion hole 421 gradually decreases toward the second end plate 22.

[0043] In actual application, the steel strand 3 is first passed through the first extrusion hole 411, and then the fixing member 42 is sleeved on the outer periphery of the extrusion member 41. The operator uses a tool to squeeze the fixing member 42 so that the fixing member 42 hugs the extrusion member 41, and then the extrusion member 41 locks the steel strand 3 to prevent the steel strand 3 from slipping. The diameter of the second extrusion hole 421 gradually decreases in the direction close to the second end plate 22, which can enhance the force of the fixing member 42 hugging the extrusion member 41, thereby increasing the locking ability of the anchor 4.

[0044] In one embodiment, see Figure 4 The extrusion piece 41 may include a plurality of extrusion portions 412 spaced apart along its circumference, and the plurality of extrusion portions 412 are circumferentially arranged to form a first extrusion hole 411. The extrusion piece 41 arranged in this way has a better extrusion effect on the steel strand 3, further enhancing the locking ability of the anchor 4.

[0045] In one embodiment, see Figure 5 The rotating groove 231 can be a fully enclosed structure along its circumference. In this way, when the rotating portion 221 extends into the rotating groove 231, the rotating portion 221 is not easy to be separated, thereby enhancing the connection stability between the anchor plate 23 and the second end plate 22.

[0046] In one embodiment, see Figure 6 The rotating groove 231 may also be a structure that is at least partially open along its circumference. In this way, the rotating portion 221 extends directly into the rotating groove 231 through the open portion, thereby realizing the rotating connection between the anchor plate 23 and the second end plate 22. Compared with the above embodiment, this embodiment makes the installation and disassembly of the anchor plate 23 more convenient and quick. The second end plate 22 can be installed first and then the anchor plate 23, and the construction is simpler.

[0047] See also Figure 7 The anchor plate 23 includes a first portion 232, a second portion 233, a third portion 234 and a fourth portion 235. The first portion 232 and the third portion 234 are connected to opposite sides of the second portion 233, respectively, and the first portion 232 and the third portion 234 extend along the height direction of the anchor plate 23; the second portion 233 and the fourth portion 235 are connected to opposite sides of the third portion 234, respectively, and the second portion 233 and the fourth portion 235 extend along the width direction of the anchor plate 23; wherein the inner side surfaces of the first portion 232, the second portion 233, the third portion 234 and the fourth portion 235 surround and form a rotation groove 231, the first portion 232 extends in a direction close to the rotation groove 231, the fourth portion 235 is spaced apart from the first portion 232, and the inner side surface of the fourth portion 235 is inclined in a direction away from the rotation groove 231.

[0048] In actual application, when the rotation groove 231 of the anchor plate 23 is an open structure, the first part 232 extends in the direction close to the rotation groove 231, which can play a role in preventing the anchor plate 23 from falling off, so that the anchor plate 23 can be hung on the rotating part 221 no matter to which angle it is rotated; the inner side surface of the fourth part 235 is inclined in the direction away from the rotation groove 231, that is, the fourth part 235 is in an outwardly open state, which makes it easy for the rotating part 221 to extend into the rotation groove 231 and to remove the anchor plate 23 from the second end plate 22.

[0049] See also Figure 8 and Fig. 9 The photovoltaic bracket includes a first reinforcing rib 5 and an ear plate 6. The ear plate 6 is connected to the upper part of the column 1. One end of the first reinforcing rib 5 is connected to the ear plate 6, and the other end is used to connect to the ground; the photovoltaic bracket also includes a locking piece 7. The first reinforcing rib 5 includes a first rib body 51 and a first connecting end 52. One end of the first connecting end 52 is connected to the first rib body 51, and the other end is provided with a first fixing hole 521 on opposite sides. The ear plate 6 is provided with a second fixing hole 61. The locking piece 7 is penetrated with the first fixing hole 521 and the second fixing hole 61 to fix the first reinforcing rib 5 and the ear plate 6.

[0050] The first reinforcing rib 5 is mainly used to increase the structural stability of the column 1 to prevent the column 1 from tilting or falling in extreme weather. The column 1 is connected with an ear plate 6, which provides a location for the first reinforcing rib 5 to be connected. The locking member 7 passes through the first fixing hole 521 and the second fixing hole 61 to achieve the fixing effect of the first reinforcing rib 5 and the ear plate 6. The first fixing member 42 can be a structure such as a screw, a rivet or a pin.

[0051] In one embodiment, the first reinforcing rib 5 and the ear plate 6 may be rotatably connected to adapt to terrain changes.

[0052] See again Figure 8 The photovoltaic support includes a second reinforcing rib 9, which is respectively connected between two adjacent columns 1.

[0053] In one embodiment, if a multi-row column 1 structure is adopted, a second reinforcing rib 9 can be arranged between adjacent columns 1 to increase the stability between the columns 1. Specifically, the second reinforcing rib 9 includes a second rib body 91 and a second connecting end 92, both ends of the second rib body 91 are connected to the second connecting end 92, and an ear plate 6 is arranged on the opposite side of two adjacent columns 1, and the second connecting ends 92 at both ends of the second rib body 91 are respectively connected to the ear plates 6 on the adjacent columns 1; multiple ear plates 6 can be arranged, and multiple second reinforcing ribs 9 can be arranged between two columns 1, and multiple second reinforcing ribs 9 can be arranged in parallel or in a cross arrangement, so as to further increase the structural stability of the columns 1.

[0054] In one embodiment, the second reinforcing rib 9 and the ear plate 6 may also be rotatably connected to adapt to terrain changes.

[0055] It should be noted that the extension direction of the steel strands 3 is set to be a row. For example, if there are two steel strands 3 , there are two rows of columns 1 .

[0056] See again Fig. 9 The photovoltaic bracket includes an anti-slip component 8, which is inserted into the locking component 7 along a direction perpendicular to the length of the locking component 7, and is used to prevent the locking component 7 from being separated from the first fixing hole 521 and the second fixing hole 61.

[0057] Specifically, the locking piece 7 is provided with an insertion hole, and the anti-slip piece 8 is inserted into the insertion hole. The length of the anti-slip piece 8 is greater than the aperture of the first fixing hole 521 and the second fixing hole 61, which can effectively prevent the locking piece 7 from falling off and causing the first reinforcement rib 5 and the ear plate 6 to separate.
