Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and in particular to a flexible tilt-tracking photovoltaic support system. Background Technology

[0002] Photovoltaic tracking systems are categorized into fixed, fixed adjustable, horizontal single-axis tracking systems, inclined single-axis tracking systems, and dual-axis tracking systems. Fixed systems have a simple structure and require minimal maintenance, making them the mainstay of the photovoltaic industry; however, their low power generation is a drawback. Fixed adjustable systems require tilt adjustment only once per quarter, resulting in a limited increase in power generation (up to 3%), and their simple structure also requires relatively little maintenance. Horizontal single-axis tracking systems follow the sun's movement daily, increasing power generation by 8-10%. However, their system structure is more complex, requiring more maintenance, and they are suitable for low- to mid-latitude regions, making them the mainstay of tracking systems.

[0003] For example, Chinese patent document CN106487322A discloses a single-axis tracking bracket, which includes a support column with an eccentric bearing mounted on the top, a main beam fixed in the eccentric bearing, a battery panel fixed above the main beam by a fixing mechanism, and a drive mechanism located on the top of the support column for driving the main beam to rotate around its own axis. The battery panel, main beam, and eccentric bearing are combined to form a rotating mechanism. The eccentric bearing is used to make the center of gravity of the rotating mechanism located on the rotation center line of the main beam. The system structure is relatively complex and requires a high level of maintenance. Summary of the Invention

The two longitudinal steel beams are connected by multiple transverse steel beams. One longitudinal steel beam is connected to a transverse tension cable at both ends, and the middle of the longitudinal steel beam is rotatably connected to a transverse end column.

[0018] like Figures 1-6 As shown, a stable flexible tilt-tracking photovoltaic support system includes multiple rows of photovoltaic supports and a longitudinal stabilizing mechanism connecting the multiple rows of photovoltaic supports.

[0019] The photovoltaic support includes a tilting component, the upper end of which is connected to a transverse tension cable. Part of the cable is rotatably connected to each transverse end column or transverse middle column, so that the tilting component rotates around a fulcrum on each transverse end column or transverse middle column.

The longitudinal support cable 91 passes through each row of photovoltaic brackets longitudinally, and its two ends are connected to the longitudinal end columns respectively. The longitudinal support cable 91 is snapped to the lower end of the stabilizing bracket in each row of photovoltaic brackets.

[0021] The longitudinal stabilization mechanism makes the multi-row photovoltaic support less susceptible to tilting due to wind force in the longitudinal direction, thus improving the longitudinal stability of the multi-row photovoltaic support.

[0022] Specifically, as an optional implementation method in this embodiment, such as Figure 2 As shown, the stabilizing support includes The stabilizing crossbar 61 has its two ends connected to two transverse tension cables 1 in each row of photovoltaic brackets, and its middle part is rotatably connected to the upper end of the stabilizing longitudinal bar 62.

[0023] Specifically, as an optional implementation method in this embodiment, such as Figure 3 As shown, the flexible tilt-tracking photovoltaic bracket also includes a transverse support cable 92, the two ends of which are connected to the transverse end columns 2 of each row of photovoltaic brackets. Specifically, as an optional implementation method in this embodiment, such as Figure 2 As shown, the transverse support cable 92 of the photovoltaic bracket is snapped together with the fixing seat 63 provided on the stabilizing longitudinal rod 62 of the stabilizing bracket.

[0024] Specifically, as an optional implementation method in this embodiment, such as Figure 3As shown, the tilting component includes an end rotating beam, which comprises a longitudinal steel beam 31 and a transverse steel beam 32. The two longitudinal steel beams 31 are connected by multiple transverse steel beams 32. One longitudinal steel beam 31 is connected at both ends to a transverse tension cable 1, and the middle of the longitudinal steel beam 31 is rotatably connected to a transverse end column 2. The transverse steel beam 32 at one end of the end rotating beam is moved up and down by a telescopic mechanism to tilt the photovoltaic panel assembly 5 installed on the transverse tension cable 1 relative to the horizontal line. The middle of the longitudinal steel beam 31 and the transverse end column 2 can be rotatably connected via a bearing assembly or other rotating assembly. The telescopic mechanism pulls the transverse steel beam 32 at one end of the end rotating beam downwards, causing the middle of the longitudinal steel beam 31 to rotate around a fulcrum of the transverse end column 2, thus tilting the photovoltaic panel assembly 5 installed on the transverse tension cable 1. Adjusting the telescopic mechanism adjusts the tilt angle of the photovoltaic panel assembly 5 without requiring manual adjustment. The telescopic mechanism can be a jack mechanism or an electric push rod, etc. The jack mechanism can be extended and retracted by an electric drive mechanism.

[0025] Specifically, as an optional implementation method in this embodiment, such as Figure 4 As shown, the tilting component includes a central rotating beam 33, with both ends of the central rotating beam 33 connected to transverse tension cables 1; the middle part of the central rotating beam 33 is rotatably connected to the transverse central column 4, and one end of the central rotating beam 33 is pulled up and down by a telescopic mechanism to make the photovoltaic panel component 5 installed on the transverse tension cable 1 tilt relative to the horizontal line.

[0026] The telescopic mechanism pulls one end of the intermediate rotating beam 33 downwards, causing the middle part of the intermediate rotating beam 33 to rotate around a fulcrum of the transverse intermediate column 4, thus tilting the photovoltaic panel assembly 5 installed on the transverse tension cable 1. Adjusting the telescopic amount of the mechanism adjusts the tilt angle of the photovoltaic panel assembly 5. The telescopic mechanism can be a jack mechanism or an electric push rod, etc. The jack mechanism can be driven by an electric drive mechanism.

[0027] Specifically, as an optional implementation method in this embodiment, such as Figures 1-6 As shown, the telescopic mechanism is a jack mechanism 7, which includes a telescopic connecting rod assembly. The top of the telescopic connecting rod assembly is connected to a top connecting seat, and the bottom of the telescopic connecting rod assembly is connected to a first bottom connecting seat and a second bottom connecting seat. For the specific structure of the jack mechanism 7, please refer to Chinese patent document CN216122326U.

[0028] Specifically, as an optional implementation method in this embodiment, such as Figures 1-6 As shown, the flexible tilt-tracking photovoltaic support system also includes a first drive cable and a second drive cable; The first drive cable and the second drive cable form a ring drive cable, which is connected between the two horizontal end columns 2 of each row of photovoltaic brackets. The first drive cable is connected to the first bottom connecting seat at the bottom of the jack mechanism 7, and the second drive cable is connected to the second bottom connecting seat at the bottom of the jack mechanism 7. When the first drive cable and the second drive cable are pulled in opposite directions, they drive the telescopic linkage assembly of the jack mechanism 7 to perform a supporting or retracting movement.

[0029] Specifically, as an optional implementation method in this embodiment, such as Figure 5 As shown, the flexible tilt-tracking photovoltaic support also includes a drive mechanism 8, which pulls a first drive cable or a second drive cable to pull the first drive cable and the second drive cable in opposite directions. The drive mechanism 8 can be a cylinder or an electric push rod, etc.

[0030] Specifically, as an optional implementation method in this embodiment, such as Figure 2 As shown, multiple support members 10 are provided on the transverse support steel cable 92 of the photovoltaic bracket. The lower end of the support member 10 is snapped to the transverse support steel cable 92. The upper end of the support member 10 is provided with a sleeve hole. The sleeve hole passes through the slide rod connected to the first bottom connecting seat at the bottom of the jack mechanism 7 or the slide rod connected to the second bottom connecting seat at the bottom of the jack mechanism 7. Alternatively, the sleeve hole passes through the first drive steel cable or the second drive steel cable.

[0031] The transverse tension cable 1, the first drive cable, the second drive cable, and the transverse support cable 92 serve as flexible components in the X-direction of the photovoltaic bracket. Multiple cables are connected between the transverse end columns 2 at both ends. End rotating beams are installed at the transverse end columns 2, and multiple transverse intermediate columns 4 and intermediate rotating beams 33 are installed in the middle. The longitudinal support cable 91 serves as a flexible component in the Y-direction of the photovoltaic bracket. The stabilizing crossbar 61 of the stabilizing bracket serves as a rigid component in the Y-direction of the photovoltaic bracket, and the stabilizing longitudinal bar 62 of the stabilizing bracket serves as a rigid component in the Z-direction of the photovoltaic bracket. The stabilizing crossbar 61 connects to the transverse tension cable 1, and the transverse support cable 92 connects to the stabilizing longitudinal bar 62. The stabilizing crossbar 61 is connected to the first drive cable and the second drive cable by a jack mechanism 7. This forms a multi-layered longitudinal and transverse connection structure. The driving mechanism 8 pulls either the first or second drive cable. The jack mechanism connecting the end rotating beam, the middle rotating beam, and the stabilizing crossbar is connected to the first driving steel cable and the second driving steel cable. The same driving mechanism 8 pulls the first driving steel cable or the second driving steel cable, so that one end of the end rotating beam, the middle rotating beam, and the stabilizing crossbar moves up and down synchronously. The multiple photovoltaic panel components 5 installed on the transverse traction steel cable 1 can tilt synchronously to form an angle.

[0032] The tilt tracking transmission system, consisting of tilt components, longitudinal stabilization mechanism, transverse tension cable 1, and solar panel 5, tracks the solar altitude angle in real time. In mid-to-high latitude regions, it can increase power generation by 8-10%, filling the gap in single-axis tracking brackets in mid-to-high latitude regions, and requires minimal maintenance.
