Description

Technical Field

[0002] In photovoltaic power generation applications, photovoltaic brackets are an important component of the photovoltaic system. Their main function is to support and fix photovoltaic modules to ensure the stability and functionality of the photovoltaic system.

[0003] In the prior art, the drive mechanism of a flat single-axis photovoltaic mounting system is structured as follows: the slewing mechanism and motor are installed in a specially designed drive mounting frame, the gear is mounted on the slewing mechanism's rotating shaft, and the drive mounting frame is also equipped with an arc bearing support to assist in the installation of the drive clamp. The fan-shaped sprocket is mounted on the drive clamp and meshes with the gear. When powered on, the rotation of the slewing mechanism's rotating shaft drives the fan-shaped sprocket, which in turn drives the main beam, ultimately achieving the purpose of tracking sunlight. However, because the drive mechanism is supported by only a single-sided arc bearing, when a flat single-axis photovoltaic mounting system is installed on a slope, the drive clamp will tilt relative to the drive mounting frame. This tilt will cause the fan-shaped sprocket to tilt as well, resulting in friction with other components, seriously affecting the product's service life. Utility Model Content

[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0042] Photovoltaic power generation is a green energy technology that converts solar radiation into direct current. With the improvement of environmental awareness and the transformation of energy structure, photovoltaic power generation has been increasingly widely used around the world and has become an important renewable energy source.

[0043] In photovoltaic power generation applications, photovoltaic brackets are an important component of the photovoltaic system. Their main function is to support and fix photovoltaic modules to ensure the stability and functionality of the photovoltaic system.

[0044] A flat single-axis photovoltaic mounting system features a single horizontal axis of rotation. Unlike traditional fixed mounting systems, it automatically adjusts the angle of the photovoltaic modules based on the sun's trajectory, maximizing sunlight capture. This intelligent design significantly improves the system's power generation efficiency.

[0045] In the prior art, the structural principle of the drive device of a flat single-axis photovoltaic support system is as follows: the slewing device and motor are installed in a special drive mounting frame, the gear is installed on the rotating shaft of the slewing device, and the drive mounting frame is also provided with an arc bearing support to assist in the installation of the drive clamp. The fan-shaped sprocket is installed on the drive clamp and meshes with the gear. When powered on, the rotation of the rotating shaft of the slewing device drives the rotation of the fan-shaped sprocket, thereby driving the rotation of the main beam, ultimately achieving the purpose of tracking sunlight. However, because the drive device is only supported by a single-sided arc bearing, when the flat single-axis photovoltaic support system is installed on a slope, the drive clamp will tilt relative to the drive mounting frame. This tilt will cause the fan-shaped sprocket to tilt as well, and then generate friction with the other components (this can be understood as friction between the fan-shaped sprocket mounting plate and the gear), seriously affecting the service life of the product.

[0046] In view of this, please refer to Figures 1-8The driving device and photovoltaic bracket provided in the embodiments of the present invention can solve this problem, which will be described in detail below.

[0047] Please refer to Figure 1 A photovoltaic bracket is provided in an embodiment of the utility model. The photovoltaic bracket includes a main beam (not shown), a column (not shown) and a driving device. The main beam is installed on the main beam support 200 of the driving device, and the mounting seat 100 of the driving device is rotatably connected to the column. Compared with the existing photovoltaic bracket, the photovoltaic bracket has a better service life.

[0048] In this embodiment, the photovoltaic support can be understood as a flat single-axis photovoltaic support system, and the number of driving devices can be multiple, and multiple driving devices are installed on the main beam.

[0049] Specifically, the driving device is suitable for a photovoltaic bracket, and the driving device includes a mounting seat 100, a main beam support 200, a first arc bearing 300, a second arc bearing 400, a fan-shaped sprocket 500 and a driving member 600. The mounting seat 100 is used to connect the column, and the main beam support 200 is used to support the main beam.

[0050] The first arc bearing 300 is rotatably mounted on the mounting seat 100, and the second arc bearing 400 is rotatably mounted on the mounting seat 100. The first arc bearing 300 and the second arc bearing 400 are spaced apart. The first arc bearing 300 and the second arc bearing 400 are both connected to the main beam support 200. The fan-shaped sprocket 500 is connected to the main beam support 200. The fan-shaped sprocket 500 is located between the first arc bearing 300 and the second arc bearing 400. The driving member 600 is mounted on the mounting seat 100. The driving member 600 cooperates with the fan-shaped sprocket 500. The driving member 600 is used to drive the fan-shaped sprocket 500 to rotate.

[0051] Since the driving device has a first arc bearing 300 and a second arc bearing 400 that are spaced apart, and the fan-shaped sprocket 500 is located between the first arc bearing 300 and the second arc bearing 400, it is equivalent to the driving device having arc bearing support on both sides, and the overall force is evenly distributed. Even if the photovoltaic bracket is installed on a slope, the fan-shaped sprocket 500 can be prevented from tilting, thereby avoiding friction between the fan-shaped sprocket 500 and other components. The fan-shaped sprocket 500 rotates more smoothly, ensuring the service life of the product.

[0052] The main beam support 200 includes a support plate 210 and a pressure plate 220 ( Figure 6 As shown), the support plate 210 has a U-shaped groove, and the U-shaped groove of the support plate 210 is used to support the main beam. The pressure plate 220 is installed on the support plate 210 to fasten the main beam to the support plate 210. The function of the structure composed of the support plate 210, the first arc bearing 300 and the second arc bearing 400 is equivalent to the driving clamp in the prior art.

[0053] The first arc bearing 300, the second arc bearing 400, and the fan-shaped sprocket 500 are all connected to the support plate 210. In this embodiment, the first arc bearing 300 and the second arc bearing 400 are connected to the support plate 210 by welding. At the same time, a connecting plate is welded to the outer wall of the support plate 210, and the connecting plate is connected to the fan-shaped sprocket 500.

[0054] It should be noted that, in this embodiment, the mounting base 100 includes a drive mounting frame 110 and an arc bearing support 120, the arc bearing support 120 is installed on the drive mounting frame 110, and the drive mounting frame 110 is used to connect the column, wherein the second arc bearing 400 is rotatably mounted on the arc bearing support 120, and the first arc bearing 300 is rotatably mounted on the drive mounting frame 110.

[0055] Among them, the first arc bearing 300 and the second arc bearing 400 are distributed in parallel, and the first arc bearing 300 and the second arc bearing 400 have the same structure. For the convenience of description, the following content may collectively refer to the first arc bearing 300 and the second arc bearing 400 as arc bearings.

[0056] In order to facilitate the driving of the sector sprocket 500, in this embodiment, please refer to Figure 7 and Figure 8 The driving member 600 includes a motor 610, a first gear 620 and a second gear (not shown). The first gear 620 and the second gear have the same structure. The motor 610 is connected to the first gear 620. The motor 610 is installed on the mounting base 100. The first gear 620 is used to cooperate with the fan-shaped sprocket 500. The motor 610 is used to drive the first gear 620 to rotate.

[0057] In addition, the second gear is connected to the motor 610, and the second gear is used to cooperate with the fan-shaped sprocket 500. The motor 610 is used to drive the second gear to rotate. It should be noted that the fan-shaped sprocket 500 has two rows of shafts ( Figure 5 as shown), so as to engage with the first gear 620 and the second gear respectively.

[0058] Specifically, the motor 610 can be understood as a rotary motor 610. The motor 610 has a rotating shaft 611. The first gear 620 and the second gear are both mounted on the outside of the rotating shaft 611. When the rotating shaft 611 of the motor 610 rotates, it drives the first gear 620 and the second gear to rotate. For the convenience of description, the subsequent content can collectively refer to the first gear 620 and the second gear as gears.

[0059] The structure of the sector sprocket 500 in this embodiment can be understood as the existing sector sprocket structure, that is, the driving device provided in this embodiment can avoid the friction between the sector sprocket mounting plate and the gear.

[0060] In addition, in order to facilitate the smooth rotation of the first arc bearing 300 and the second arc bearing 400, please refer to Figure 4 Combined with Figure 1 In this embodiment, the arc bearing support 120 has a first roller 122 and a second roller 123 that are spaced apart. Specifically, the arc bearing support 120 includes a first main frame 124 ( Figure 2 As shown) and a first roller 122 and a second roller 123 rotatably mounted on the top of the first main frame 124, the first arc bearing 300 has a first arc-shaped outer wall 310 and a first arc-shaped inner wall 320 opposite to the first arc-shaped outer wall 310, the first roller 122 is used to roll against the first arc-shaped outer wall 310, and the second roller 123 is used to roll against the first arc-shaped inner wall 320.

[0061] In addition, the drive mounting frame 110 has a third roller (not shown) and a fourth roller (not shown) that are spaced apart. Specifically, the drive mounting frame 110 includes a second main frame body 111 ( Figure 3 As shown) and a third roller and a fourth roller rotatably mounted on the top of the second main frame 111, the second arc bearing 400 has a second arc-shaped outer wall 410 and a second arc-shaped inner wall 420 opposite to the second arc-shaped outer wall 410, the third roller is used to roll against the second arc-shaped outer wall 410, and the fourth roller is used to roll against the second arc-shaped inner wall 420.

[0062] The structure of the third roller can refer to the structure of the first roller 122 mentioned above, and the structure of the fourth roller can refer to the structure of the second roller 123 mentioned above. It is easy to understand that Figure 2 and Figure 3 As shown, the top structure of the arc bearing support 120 is similar to or identical to the top structure of the drive mounting frame 110, the top structure of the arc bearing support 120 and the top structure of the drive mounting frame 110 can be located at the same height, and the top structure of the arc bearing support 120 and the top structure of the drive mounting frame 110 are both used to support the arc bearing.

[0063] In addition, it should be noted that Figure 2 As shown, the first main frame 124 of the arc bearing support 120 is provided with an axial hole 121 , and the axial hole 121 is used to support the end of the rotating shaft 611 of the driving member 600 .

[0064] It should be noted that in order to facilitate the connection between the drive mounting frame 110 and the column, and at the same time, to facilitate the photovoltaic bracket to be suitable for slope installation, the lower side plate of the second main frame body 111 of the drive mounting frame 110 is provided with a circular column mounting hole and multiple arc holes adjacent to the circular column mounting hole (the number of arc holes here is three). The arc holes can facilitate the adjustment of the rotation angle of the drive mounting frame 110 relative to the column, so that the photovoltaic bracket can be suitable for slope installation.

[0065] For example, a fastener (such as a screw or bolt) is passed through the column mounting hole to connect to the column, and a fastener can also be passed through the arc hole to connect to the column to ensure the connection strength between the drive mounting frame 110 and the column.

[0066] Generally speaking, bolts are installed between the column mounting holes and the corresponding connection positions of the columns. At the same time, three bolts are installed between the three arc-shaped holes and the corresponding connection positions of the columns. The locking process of the four bolts is not performed for the time being. Then, the rotation angle of the second main frame 111 of the drive mounting frame 110 relative to the column is adjusted according to the terrain of the installation site (equivalent to the drive mounting frame 110 being able to rotate around the axis of the circular column mounting hole). After completing the rotation angle adjustment, tighten the four bolts to ensure the connection strength between the drive mounting frame 110 and the column.

[0067] Alternatively, when it is necessary to adjust the rotation angle of the drive mounting frame 110 relative to the column, loosen the bolts at the arc hole position and the bolts at the column mounting hole position. After completing the adjustment of the rotation angle of the second main frame 111 of the drive mounting frame 110 relative to the column, tighten the bolts at the arc hole position and the bolts at the column mounting hole position to achieve a firm connection between the drive mounting frame 110 and the column.

[0068] Generally speaking, during the installation of the driving device, the motor 610 can be installed on the driving mounting frame 110, and the rotating shaft of the motor 610 can be staggered to place the first gear 620 and the second gear (the staggered placement here can be understood as the teeth of the first gear 620 and the teeth of the second gear are staggered, that is, along the axial direction of the rotating shaft, the projection of the teeth of the first gear 620 and the projection of the teeth of the second gear do not overlap).

[0069] Then, install the arc bearing support 120 in the corresponding position on the drive mounting frame 110, and install the sector sprocket 500 in the corresponding position on the connecting plate at the support plate 210. Install the third and fourth rollers on the top structure of the drive mounting frame 110, and the first and second rollers 122 and 123 on the top structure of the arc bearing support 120.

[0070] The main beam support 200 connected with the first arc bearing 300, the second arc bearing 400 and the sector sprocket 500 is installed on the driving mounting frame 110 and the arc bearing support 120, and the sector sprocket 500 is engaged with the gear.

[0071] The main beam is installed within the U-shaped groove of the support plate 210. The support plate 210 is covered with a pressure plate 220 and locked. The corresponding photovoltaic panel assembly is mounted on the main beam. When the motor 610 is powered, the rotating shaft drives the fan-shaped sprocket 500, which in turn rotates the main beam, ultimately achieving the desired tilt angle of the photovoltaic panel assembly.

[0072] To sum up, the driving device is suitable for a photovoltaic bracket, and the driving device includes a mounting seat 100, a main beam support 200, a first arc bearing 300, a second arc bearing 400, a fan-shaped sprocket 500 and a driving member 600. The mounting seat 100 is used to connect the column, the main beam support 200 is used to support the main beam, the first arc bearing 300 is rotatably mounted on the mounting seat 100, the second arc bearing 400 is rotatably mounted on the mounting seat 100, the first arc bearing 300 and the second arc bearing 400 are distributed at intervals, the first arc bearing 300 and the second arc bearing 400 are both connected to the main beam support 200, the fan-shaped sprocket 500 is connected to the main beam support 200, the fan-shaped sprocket 500 is located between the first arc bearing 300 and the second arc bearing 400, the driving member 600 is installed on the mounting seat 100, the driving member 600 cooperates with the fan-shaped sprocket 500, and the driving member 600 is used to drive the fan-shaped sprocket 500 to rotate.

[0073] Since the driving device has a first arc bearing 300 and a second arc bearing 400 that are spaced apart, and the fan-shaped sprocket 500 is located between the first arc bearing 300 and the second arc bearing 400, it is equivalent to the driving device having double-sided arc bearing support, and the overall force is evenly distributed. Even if the photovoltaic bracket is installed on a slope, the fan-shaped sprocket 500 can be prevented from tilting, thereby avoiding friction between the fan-shaped sprocket 500 and other components, thereby ensuring the service life of the product.

[0074] In addition, the driving device is not only applicable to the situation where the photovoltaic bracket is installed on a flat surface, but also to the situation where the photovoltaic bracket is installed on a slope. When the photovoltaic bracket is installed on a slope, the driving device ensures that the photovoltaic bracket rotates smoothly and stably.

[0075] The driving device has a simple structure, is easy to manufacture and install, has low cost and high reliability.

[0076] The photovoltaic support includes a main beam, a column and the above-mentioned driving device. The main beam is installed on the main beam support 200, and the mounting seat 100 is rotatably connected to the column. The photovoltaic support has all the functions of the above-mentioned driving device.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
