[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] The present invention provides Figure 1-5 A dual-axis photovoltaic tracking bracket is shown, which is used to support and fix a photovoltaic module 1, and includes a plurality of hollow columns 3, a support rod 5 is provided between two adjacent columns 3, and an adjustment frame 6 is fixed on the support rod 5;

[0034] The top of the support rod 5 is provided with a photovoltaic panel bracket 2, the photovoltaic assembly 1 is installed on the photovoltaic panel bracket 2, one end of the support rod 5 is movably connected to one of the columns 3 through a bearing, a third gear 21 is fixedly provided at the outer end of the support rod 5, a first gear 7 meshing with the third gear 21 is provided at the outer end of one of the columns 3, and a first motor 9 for driving the first gear 7 is fixedly provided on the inner wall of the column 3;

[0035] The tracking bracket is mainly composed of a plurality of columns 3 fixed on the ground and a support rod 5 between two adjacent columns 3. Since the bracket is supported by a plurality of columns 3, the bracket has better stability and the strongest wind resistance, and the requirements for the foundation are also reduced.

[0036] The columns 3 are arranged horizontally from south to north on the ground, and the third gear 21 fixed on the support rod 5 is meshed with the first gear 7. The first motor 9 inside the column 3 can drive the first gear 7 to rotate, thereby driving the third gear 21 and the support rod 5 to rotate. The rotation of the support rod 5 drives the photovoltaic panel bracket 2 and the photovoltaic component 1 to rotate forward and backward, thereby adjusting the inclination angle of the photovoltaic component 1 from the east-west direction.

[0037] In addition to the east-west direction, the photovoltaic module 1 can also be adjusted to tilt toward the south, such as Figure 1-4 As shown, a gear shaft 12 is provided on the inner wall of the adjusting frame 6 through a rotating shaft, a second gear 13 is fixedly provided at the outer end of the gear shaft 12, a second motor 11 for driving the gear shaft 12 to rotate is fixedly provided on the rear side of the adjusting frame 6, one end of the photovoltaic panel bracket 2 is hinged to the top end of the support rod 5, and a serrated bracket 10 is fixedly provided at the other end of the photovoltaic panel bracket 2, the serrated bracket 10 passes through the adjusting frame 6 and meshes with the second gear 13.

[0038] After the second motor 11 is turned on, the second motor 11 can drive the gear shaft 12 and the second gear 13 to rotate, and the second gear 13 is meshed with the serrated bracket 10 fixed on the photovoltaic panel bracket 2, so the rotation of the second gear 13 can drive the serrated bracket 10 to move, and the serrated bracket 10 drives one end of the photovoltaic panel bracket 2 to move up and down, and the other end of the photovoltaic panel bracket 2 is hinged to the support rod 5, so the serrated bracket 10 makes the inclination angle of the photovoltaic panel bracket 2 and the photovoltaic assembly 1 towards the south constantly change;

[0039] In this way, the angle of the photovoltaic module 1 can be adjusted according to the changes in the position of the sun during the day, so that the photovoltaic module 1 can track the changes in the angle of the sun synchronously. The photovoltaic module 1 can always face the sun, and the efficiency of power generation is higher.

[0040] After the angle is adjusted, the photovoltaic module 1 and the photovoltaic panel support 2 need to be fixed at this angle, such as Figure 2 , 7 As shown, one end of the support rod 5 is provided with a positioning bracket 4 through a rotating shaft, one end of the support rod 5 extends into the interior of the positioning bracket 4 and is fixed with a positioning plate 17, and the positioning bracket 4 is fixedly arranged at the outer end of another column 3;

[0041] A pressure plate 19 is disposed inside the positioning bracket 4 , and two second cylinders 18 are disposed between the pressure plate 19 and another column 3 . The second cylinders 18 can push the pressure plate 19 to make close contact with the positioning plate 17 .

[0042] The angle of the photovoltaic module 1 in the east-west direction is adjusted by rotating the support rod 5. When the support rod 5 rotates, the positioning plate 17 fixed at one end of the support rod 5 rotates synchronously with the support rod 5. After the angle of the photovoltaic module 1 is adjusted, the pressure plate 19 can be pushed toward the positioning plate 17 by the second cylinder 18 until the pressure plate 19 is in close contact with the positioning plate 17. After the two are in close contact, the friction between the pressure plate 19 and the positioning plate 17 will limit the further rotation of the positioning plate 17, thereby fixing the angle of the support rod 5 and the photovoltaic module 1.

[0043] Similarly, the inclination angle of the photovoltaic module 1 to the south can also be fixed, such as Figure 4 As shown, a waterproof cover is provided on the rear side of the adjusting frame 6, and the second motor 11 is arranged inside the waterproof cover to prevent the second motor 11 from being damaged by moisture in the outdoor environment. Two first cylinders 14 are fixedly provided on the inner wall of the adjusting frame 6, and an arc plate 15 is fixedly provided at one end of the first cylinder 14. The first cylinder 14 can push the arc plate 15 to be in close contact with the gear shaft 12, thereby limiting the rotation of the gear shaft 12.

[0044] When the second gear 13 drives the serrated bracket 10 to move and adjusts the tilt angle of the photovoltaic module 1 to the south, the first cylinder 14 pushes the arc plate 15 to move, so that the arc plate 15 is in close contact with the outer end of the gear shaft 12, limiting the further rotation of the gear shaft 12 and the second gear 13, thereby fixing the serrated bracket 10 and the photovoltaic panel bracket 2, and further fixing the tilt angle of the photovoltaic module 1 to the south.

[0045] When the wind blows, the photovoltaic module 1 will also generate wind resistance. In order to buffer the wind force, Figure 3 As shown, the photovoltaic panel support 2 includes a lower support plate 201, an upper support plate 202 is provided on the top of the lower support plate 201, the photovoltaic assembly 1 is detachably provided on the top of the upper support plate 202, the serrated support 10 is fixedly provided on the lower support plate 201, and the support rod 5 is also hinged to the lower support plate 201;

[0046] A ball hinge 203 and a plurality of springs 204 are provided between the upper supporting plate 202 and the lower supporting plate 201 . The ball hinge 203 is located at the center of the lower supporting plate 201 , and the springs 204 are located at the corners thereof.

[0047] The entire photovoltaic panel bracket 2 is composed of two layers, a lower support plate 201 and an upper support plate 202. The photovoltaic component 1 is located on the upper support plate 202, and the upper support plate 202 and the lower support plate 201 are connected by a ball hinge 203 and a spring 204. When wind blows towards the photovoltaic component 1 and the upper support plate 202, the wind will cause the upper support plate 202 to tilt relative to the lower support plate 201 under the action of the ball hinge 203, and the spring 204 in the tilting direction will be compressed, so that the elastic force of the compressed spring 204 is used to buffer the wind.

[0048] In order to dissipate heat from the first gear 7 inside the column 3, as Figure 1 , 6 As shown, a plurality of air-permeable nets 8 are provided at the outer end of the column 3, and the air-permeable nets 8 face in all directions so that wind from all directions can blow into the interior of the column 3. An inspection plate is provided on the front side of the photovoltaic module 1 through bolts, and a plurality of strip-shaped heat dissipation nets are provided on the inspection plate. A base 20 is fixedly provided at the bottom end of the column 3.

[0049] The column 3 is fixed on the ground through the base 20. When it is windy, the external air will be blown into the cavity inside the column 3 through the breathable net 8, and finally blown out through the strip heat dissipation net, so as to dissipate the heat of the first motor 9 in the cavity of the column 3.

[0050] In order to facilitate the maintenance of the photovoltaic module 1, Figure 1 , 6As shown, a climbing assembly 16 is provided at the rear side of the column 3, and the climbing assembly 16 includes two end plates 1601 fixedly provided at the rear side of the column 3, and a plurality of beams 1602 are provided between the two end plates 1601. Through the beams 1602, it is possible to climb upward along the column 3 so as to inspect and repair the photovoltaic assembly 1, and a safety door 1603 for protecting the beams 1602 is provided between the two end plates 1601;

[0051] One side of the safety door 1603 is movably connected to one of the end plates 1601 via a hinge, and the other side of the safety door 1603 is provided with a mechanical lock for connecting to the other end plate 1601. After the safety door 1603 is closed and the mechanical lock is locked, the beam 1602 is enclosed between the two end plates 1601.

[0052] The photovoltaic module 1 is supported at a high place by the column 3 and the support rod 5. When maintenance is required, relevant personnel need to climb to a high place. For this purpose, a climbing component 16 is arranged at the rear side of the column 3. When maintenance is required, the safety door 1603 is opened to expose the crossbeam 1602. The end plate 1601 and the crossbeam 1602 together play the role of a ladder. Along the climbing component 16, the maintenance personnel can climb to a high place to perform maintenance on the photovoltaic module 1.

[0053] When not in use, the safety door 1603 is closed and locked with a mechanical lock. The safety door 1603 allows the crossbeam 1602 to be enclosed between the two end plates 1601 to prevent strangers from climbing to a high place and causing danger.

[0054] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
