Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and particularly to a tracking support system and a photovoltaic power generation device. Background Art

[0002] Photovoltaic power generation devices are one of the most important forms of solar energy utilization at present. In order to improve the power generation and economic benefits of photovoltaic power generation devices, a tracking support system is usually used to support and fix photovoltaic modules. The tracking support system adjusts the angle of the tracking support system through a tracking controller, so that sunlight is vertically irradiated on the photovoltaic modules as much as possible, ensuring that the photovoltaic modules can receive more sunlight, thereby improving the power generation efficiency.

[0003] Existing tracking support systems usually include a rotating main shaft, a slewing drive assembly, and a plurality of support columns. The rotating main shaft extends in a first direction, and the plurality of support columns are arranged at intervals in the first direction and jointly support the rotating main shaft. The slewing drive assembly is arranged on the rotating main shaft and is used to drive the rotating main shaft to rotate, so that the rotating main shaft drives the photovoltaic modules to rotate. Since the housing of the slewing drive assembly is usually sleeved on the rotating main shaft and fixed on the support columns, in order to prevent the slewing drive assembly from interfering with the rotation of the photovoltaic modules, the installation of the photovoltaic modules on the tracking support system needs to avoid the installation position of the slewing drive assembly on the rotating main shaft, reducing the installation amount of the photovoltaic modules on the tracking support system.

[0051] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the present invention will be further described below with reference to the drawings and through specific implementation manners.

[0052] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to" and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0053] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above" and "on the top" of the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below" and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0054] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", and "right" are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0055] As Figure 1 shown, this embodiment provides a photovoltaic power generation device for converting the light energy emitted by solar energy into electric energy. Specifically, the photovoltaic power generation device includes a tracking support system 100 and photovoltaic modules 200. Among them, the photovoltaic modules 200 are the core components in the photovoltaic power generation device and can convert light energy into electric energy. The tracking support system 100 is used to support and fix the photovoltaic modules 200, and the tracking support system 100 can be applied to flat ground and water pile power stations, having high versatility.

[0056] Now in combination with Figures 1 to 3 the specific structure of the tracking support system 100 will be described. The tracking support system 100 includes a rotating main shaft 2 and a plurality of support columns 1. Among them, the rotating main shaft 2 extends along the first direction ( Figure 1 and Figure 3 the X direction in Figure 1 ), the plurality of support columns 1 are arranged at intervals along the X direction and jointly support the rotating main shaft 2. The rotating main shaft 2 can drive the photovoltaic modules 200 to rotate, so as to ensure that the sunlight can always be perpendicularly irradiated on the photovoltaic modules 200, thereby improving the power generation efficiency of the photovoltaic modules 200. It should be noted that, as Figure 3 shown, there are multiple groups of photovoltaic modules 200. The multiple groups of photovoltaic modules 200 are assembled and connected side by side along the X direction. By setting multiple groups of photovoltaic modules 200, the power generation efficiency of the photovoltaic power generation device is improved. The length of the rotating main shaft 2 extending along the X direction can be set according to the overall length of the assembly of the photovoltaic modules 200. As

[0057] shown, in this embodiment, as Figure 3 shown, the tracking support system 100 further includes a support assembly 5. The support assembly 5 is fixed on the rotating main shaft 2, and the support assembly 5 is used to support and fix the photovoltaic modules 200.

[0058] Specifically, as Figure 4As shown in the figure, the support assembly 5 includes two sets of triangular support frames 51 arranged side by side in the width direction of the photovoltaic module 200. Both sets of triangular support frames 51 are fixed on the rotating main shaft 2 and jointly support the photovoltaic module 200. Due to the high stability of the triangular support structure, the support stability of the support assembly 5 for the photovoltaic module 200 is improved.

[0059] Now, in combination with Figure 4 the specific structure of the triangular support frame 51 will be described. The triangular support frame 51 includes a support cross beam 511, a support inclined beam 512, and a fixing block 513. Among them, the support cross beam 511 is used to support and fix the photovoltaic module 200. Both ends of the support cross beam 511 are connected with support inclined beams 512. The fixing block 513 is fixed on the rotating main shaft 2, and the free end of the support inclined beam 512 is fixed to the fixing block 513, so that a stable triangular support structure is formed between the support cross beam 511 and the two support inclined beams 512. In addition, it should be noted that in this embodiment, the fixing block 513 can be fixed on the rotating main shaft 2 through a U-shaped bolt. The U-shaped bolt can increase the contact area between the U-shaped bolt and the rotating main shaft 2, thereby improving the reliability of the fixed connection between the fixing block 513 and the rotating main shaft 2.

[0060] In addition, as Figure 3 shown, the tracking support system 100 further includes a slewing drive assembly 3 and a tracking controller (not shown in the figure). The tracking controller is used to detect the irradiation angle of sunlight. The slewing drive assembly 3 is electrically connected to the tracking controller. The slewing drive assembly 3 is arranged on the rotating main shaft 2. The tracking controller can control the slewing drive assembly 3 to drive the rotating main shaft 2 to drive the photovoltaic module 200 to rotate, so as to ensure that sunlight can always be vertically irradiated on the photovoltaic module 200.

[0061] In the prior art, since the housing of the slewing drive assembly 3 is usually sleeved on the rotating main shaft 2 and fixed on the support column 1, in order to prevent the slewing drive assembly 3 from interfering with the rotation of the photovoltaic module 200, the installation of the photovoltaic module 200 on the tracking support system 100 needs to avoid the installation position of the slewing drive assembly 3 on the rotating main shaft 2, thereby reducing the installation amount of the photovoltaic module 200 on the tracking support system 100.

[0062] In order to solve the above problems, the slewing drive assembly 3 provided in this embodiment includes a slewing bearing and a rotating shell sleeved on the outside of the slewing bearing, the slewing bearing is sleeved on the rotating main shaft 2 and fixed on the supporting column 1, when the slewing drive assembly 3 drives the rotating main shaft 2 to drive the photovoltaic assembly 200 to rotate, the rotating shell can rotate relative to the slewing bearing synchronously with the rotating main shaft 2. This setting method makes it possible to install the photovoltaic assembly 200 on the tracking bracket system 100 without avoiding the installation position of the slewing drive assembly 3 on the rotating main shaft 2, and can make full use of the installation space of the tracking bracket system 100 for the photovoltaic assembly 200, improve the utilization rate of the installation space of the tracking bracket system 100, and thus increase the installation volume of the tracking bracket system 100 for the photovoltaic assembly 200.

[0063] In order to meet the requirements of assembling and installing multiple groups of photovoltaic modules 200 on the rotating main shaft 2, the length of the rotating main shaft 2 extending along the X direction is usually longer, in order to ensure that the rotating main shaft 2 stably drives the photovoltaic module 200 to rotate. In the prior art, multiple groups of rotary drive components 3 are usually provided, and the multiple groups of rotary drive components 3 are arranged at intervals along the X direction, and the multiple groups of rotary drive components 3 are electrically controlled to synchronously drive the rotating main shaft 2 to rotate. However, during the application of the rotary drive components 3, there are deviations in the braking accuracy of each rotary drive component 3, resulting in asynchronous rotation of the rotating main shaft 2 at various positions, causing the rotating main shaft 2 to twist with each other at different positions, which is easy to damage the rotating main shaft 2.

[0064] In order to solve the above problems, Figure 3 As shown, the rotary drive assembly 3 provided in this embodiment includes a main rotary assembly 31 and a plurality of slave rotary assemblies 32 which are connected in transmission. The main rotary assembly 31 and the plurality of slave rotary assemblies 32 are arranged at intervals along the X direction on the rotating main shaft 2, and the main rotary assembly 31 and the plurality of slave rotary assemblies 32 can synchronously drive the rotating main shaft 2 to rotate. Due to the transmission connection between the main rotary assembly 31 and the plurality of slave rotary assemblies 32, it is possible to ensure that the main rotary assembly 31 and the plurality of slave rotary assemblies 32 synchronously drive the rotating main shaft 2, avoid mutual torsion on the rotating main shaft 2, and improve the protection of the rotating main shaft 2.

[0065] Specifically, if Figure 4 and Figure 5 As shown, the main rotating assembly 31 includes a main rotating bearing 311 and a main rotating housing 312 rotatably sleeved on the outside of the main rotating bearing 311, and the main rotating bearing 311 is sleeved on the rotating main shaft 2 and fixed on one of the supporting columns 1. When the main rotating assembly 31 drives the rotating main shaft 2 to drive the photovoltaic assembly 200 to rotate, the main rotating housing 312 can rotate synchronously with the rotating main shaft 2 relative to the main rotating bearing 311.

[0066] like Figure 6As shown, the slave slewing assembly 32 includes a slave slewing bearing 321 and a slave slewing housing 322 rotatably sleeved on the outside of the slave slewing bearing 321. The slave slewing bearing 321 corresponds to the remaining support columns 1 one by one. The slave slewing bearing 321 is sleeved on the rotating main shaft 2 and fixed on the corresponding support column 1. When the slave slewing assembly 32 synchronously drives the rotating main shaft 2 to drive the photovoltaic assembly 200 to rotate, the slave slewing housing 322 can rotate synchronously with the rotating main shaft 2 relative to the slave slewing bearing 321.

[0067] In addition, if Figure 5 As shown, a driving motor 313 is also provided on the main rotating component 31. The driving motor 313 is the power source of the main rotating component 31. The driving motor 313 can drive the rotating main shaft 2 to rotate. Since the main rotating component 31 is connected with the slave rotating component 32 by transmission, the main rotating component 31 can synchronously drive the slave rotating component 32 to rotate, and the slave rotating component 32 further drives the rotating main shaft 2 to rotate, so that the main rotating component 31 and multiple slave rotating components 32 synchronously drive the rotating main shaft 2 to rotate.

[0068] In the prior art, the main rotating assembly 31 and each slave rotating assembly 32 are usually connected by a mechanical connecting rod. However, the spacing between each supporting column 1 is large, which makes the span of the mechanical connecting rod support point large. In addition, the mechanical connecting rod has insufficient bending resistance, and the mechanical connecting rod is prone to "rope skipping" during the transmission process, affecting the stability of the transmission connection.

[0069] In order to solve the above problems, Figures 4 to 6As shown, the tracking support system 100 further includes a transmission assembly 4, and the transmission assembly 4 is used to realize the transmission connection between the main slewing assembly 31 and each slave slewing assembly 32. Specifically, the transmission assembly 4 includes a transmission rod 41, and the transmission rod 41 extends along the X direction. First main output shafts 3121 protrude from both ends of the main rotating housing 312, and the first main output shafts 3121 are fixedly connected to the transmission rod 41. A second main output shaft is further provided on the main rotating housing 312, and the second main output shaft is fixedly connected to the rotating main shaft 2. Slave input shafts 3221 protrude from both ends of the slave rotating housing 322, and the slave input shafts 3221 are fixedly connected to the transmission rod 41. The slave output shaft of the slave slewing assembly 32 is fixedly connected to the rotating main shaft 2. The driving motor 313 is connected to the first main output shaft 3121 and the second main output shaft. The driving motor 313 can drive the first main output shaft 3121 and the second main output shaft to rotate. The first main output shaft 3121 then drives the transmission rod 41 to rotate, and the transmission rod 41 then drives the slave input shaft 3221 to rotate, finally enabling the slave output shaft of the slave slewing assembly 32 and the second main output shaft of the main slewing assembly 31 to synchronously drive the rotating main shaft 2 to rotate. By providing the transmission rod 41, the transmission connection between the main slewing assembly 31 and each slave slewing assembly 32 can be realized. The structure is simple, and the setting of the transmission rod 41 is not affected by the spacing between the support columns 1, making the transmission connection between the main slewing assembly 31 and each slave slewing assembly 32 more stable.

[0070] Further, as Figure 4 shown, the transmission assembly 4 further includes multiple groups of transmission connectors 42. The multiple groups of transmission connectors 42 are arranged at intervals along the X direction. The transmission connectors 42 can fixedly connect the transmission rod 41 to the rotating main shaft 2, thereby realizing the multi-point support and fixation between the transmission rod 41 and the rotating main shaft 2, further ensuring the stability of the transmission connection between the main slewing assembly 31 and each slave slewing assembly 32, and avoiding the "skipping rope" phenomenon.

[0071] Now in combination with Figure 4 the specific structure of the transmission connector 42 will be described. The transmission connector 42 includes a connecting plate 421 and a U-shaped fastener 422. The connecting plate 421 is sleeved and fixed on the transmission rod 41, and the U-shaped fastener 422 is used to fix the connecting plate 421 to the rotating main shaft 2. Specifically, the U-shaped fastener 422 can be a U-shaped bolt. Since the rotating main shaft 2 is a tubular structure, the U-shaped bolt can increase the contact area between the U-shaped bolt and the rotating main shaft 2, thereby improving the reliability of the fixed connection between the connecting plate 421 and the rotating main shaft 2.

[0072] Now in combination with Figure 7The specific structure of the support column 1 is described. The support column 1 includes a column main body 11, a first connecting seat 12, and a second connecting seat 13. The first connecting seat 12 is fixed to the end of the column main body 11. One end of the second connecting seat 13 is fixed to the first connecting seat 12, and the other end of the second connecting seat 13 is fixed to the main slewing bearing 311 or the slave slewing bearing 321. By providing the first connecting seat 12 and the second connecting seat 13, the connection stability between the column main body 11 and the main slewing bearing 311 and the slave slewing bearing 321 can be improved. Specifically, the fixation between the first connecting seat 12 and the column main body 11, the fixation between the second connecting seat 13 and the first connecting seat 12, and the fixation between the second connecting seat 13 and the slewing bearing can all be connected by a bolt group. The bolt group is a detachable connection, and the connection by the bolt group has the advantages of reliable connection and low cost.

[0073] Preferably, as Figure 7 shown, the first connecting seat 12 includes a first fixing plate 121, a second fixing plate 122, and a first reinforcing rib 123. The first fixing plate 121 is fixed to the column main body 11. The second fixing plate 122 is connected to the first fixing plate 121. The first reinforcing rib 123 is fixed between the first fixing plate 121 and the second fixing plate 122. By providing the first reinforcing rib 123, the structural strength of the entire first connecting seat 12 is enhanced, thereby ensuring the effective support of the first connecting seat 12 for the second connecting seat 13 and the slewing bearing.

[0074] In addition, as Figure 7 shown, the second connecting seat 13 includes a third fixing plate 131, a fourth fixing plate 132, and a second reinforcing rib 133. The third fixing plate 131 is fixedly attached to the second fixing plate 122. The fourth fixing plate 132 is connected to the third fixing plate 131. The fourth fixing plate 132 is fixed to the slewing bearing. The second reinforcing rib 133 is fixed between the third fixing plate 131 and the fourth fixing plate 132. By providing the second reinforcing rib 133, the structural strength of the entire second connecting seat 13 is enhanced, thereby ensuring the effective support of the second connecting seat 13 for the slewing bearing.

[0075] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention.
