[0044] Example 1

[0045] Combined with Figure 1-9This embodiment provides a flexible tracking support system, including:

[0046] Two first support drive assemblies 100, each used to be connected to the support base 8;

[0048] Motor 5;

[0049] The intermediate support driving assembly 200 includes an intermediate column 61, an intermediate reducer 23 and an intermediate main beam 62. One end of the intermediate column 61 is used to connect with the support base 8, and the other end of the intermediate column 61 is connected with the intermediate reducer 23.

[0050] Among them, the middle column 61 , the middle reducer 23 and the middle main beam 62 are all located between the two first support drive assemblies 100 .

[0051] Specifically, the two first support drive assemblies 100 are respectively used to support the two ends of the load-bearing cable 4; the load-bearing cable 4 is used to carry the photovoltaic assembly 7; the intermediate support drive assembly 200 is used to support the middle part of the load-bearing cable 4 to prevent the load-bearing cable 4 from excessively sagging; the intermediate column 61 is used to support the intermediate reducer 23; the intermediate reducer 23 is driven by the motor 5 and is used to drive the intermediate main beam 62 to rotate; the intermediate main beam 62 is used to carry and drive the load-bearing cable 4 to rotate to prevent the load-bearing cable 4 from seriously sagging. Since the intermediate main beam 62 and the load-bearing cable 4 are movably connected, it is equivalent to that the intermediate main beam 62 realizes a through-type design, which makes it easier for the load-bearing cable 4 to move along its axial direction, thereby facilitating the reduction of the force requirements on the intermediate main beam 62, and then only one intermediate main beam 62 is required, and the cross-sectional area of ​​the intermediate main beam 62 is small, so that the intermediate main beam 62 can meet the force requirements.

[0052] Further, such as Figure 3 A through hole 621 is provided on the middle main beam 62, and the load-bearing cable 4 passes through the through hole 621.

[0053] Specifically, the through hole 621 is used to accommodate the load-bearing cable 4 .

[0054] Further, such as Figure 3 The number of the load-bearing cables 4 is two, and the two load-bearing cables 4 are axially symmetrically arranged about the middle main beam 62.

[0055] Specifically, two load-bearing cables 4 arranged axially symmetrically facilitate increasing the supporting stability of the photovoltaic assembly 7 and preventing the photovoltaic assembly 7 and the flexible tracking bracket system from being separated from each other.

[0056] Further, such as Figure 2 , each first support drive assembly 100 comprises:

[0057] A first reducer 21, wherein an input end of the first reducer 21 is connected to an output shaft of the motor 5;

[0058] Side columns 31, one end of each of which is connected to the support base 8, and the other end of each of which is connected to the first reducer 21;

[0059] The side main beam 33 is connected to the output shaft of the first reducer 21;

[0060] The load-bearing cable 4 is connected between the side main beams 33 of the two first support drive assemblies 100 .

[0061] Specifically, during operation, the output shaft of the motor 5 drives the output shaft of the first reducer 21 to rotate, the output shaft of the first reducer 21 drives the side main beam 33 to rotate, the side main beam 33 drives the load-bearing cable 4 to rotate, and the load-bearing cable 4 drives the photovoltaic component 7 to rotate, thereby completing the tracking of the photovoltaic component 7.

[0062] Further, such as Figure 3 Each first support driving assembly 100 further includes a side-pull anchor 32 , one end of the side-pull anchor 32 is used to be connected to the support base 8 , and the other end of the side-pull anchor 32 is connected to the first reducer 21 .

[0064] Further, such as Figure 6 , the first reducer 21 includes:

[0065] Housing 14;

[0066] The output shaft of the first reducer 21 is configured as the mother shaft 15, which is rotatably connected to the mother shaft 15 in the housing 14 through the first bearing 11. The mother shaft 15 is connected to the side main beam 33 and the output shaft of the motor 5.

[0068] The third bearing 13 is sleeved on the outer side of the sub-shaft 16 , and one side of the third bearing 13 is in contact with the end of the mother shaft 15 .

[0069] Specifically, during operation, the output shaft of the motor 5 drives the mother shaft 15 to rotate, and the mother shaft 15 drives the side main beam 33 to rotate; wherein, the housing 14 is used to carry the first bearing 11, the mother shaft 15, etc.; the first bearing 11 is used to realize the relative rotation between the mother shaft 15 and the housing 14, and the first bearing 11 is mainly used to bear radial loads, and the first bearing 11 can be an angular contact ball bearing, a tapered roller bearing, etc.; the second bearing 12 is used to realize the relative rotation between the mother shaft 15 and the sub-shaft 16, and the second bearing 12 is mainly used to bear radial loads, and the second bearing 12 can be an angular contact ball bearing, a tapered roller bearing, etc.; the third bearing 13 is used to bear the mutual axial force between the sub-shaft 16 and the mother shaft 15, Thereby reducing the mutual axial friction between the sub-shaft 16 and the mother shaft 15, the third bearing 13 is preferably a thrust bearing; the sub-shaft 16 is used to connect with the side anchor 32, which is equivalent to the connection between the side anchor 32 and the rotation center of the reducer, so as to avoid the side anchor 32 being fixed on the side column 31 or the installation node of the reducer (that is, the installation connection between the reducer and the side column 31, the side main beam 33 and other components), and it is not easy to generate additional load on the installation node of the side column 31 or the reducer, thereby preventing the installation node of the reducer from being wasted and complicated. At the same time, the reducer adopts the design of the sub-shaft 16 and the mother shaft 15, and can be installed in the factory, which can not only reduce the amount of engineering work on the construction site, but also improve the installation quality of the reducer.

[0070] Further, such as Figure 2 and 6 The first reducer 21 also includes a support shaft 17 connected to the sub-shaft 16, and the other end of the side anchor 32 is rotatably connected to the support shaft 17.

[0071] Specifically, the support shaft 17 is used to support the other end of the side anchor 32, so as to allow a certain degree of mobility between the side anchor 32 and the sub-shaft 16 to prevent breakage.

[0072] Further, such as Figure 1-2 The two first support drive assemblies 100 are axially symmetrically distributed about the load-bearing cable 4.

The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
