Description

Technical Field

[0001] This utility model relates to the field of tracking bracket technology, specifically to a flexible tracking bracket side column drive structure that is easy to replace. Background Technology

[0002] Traditional rigid tracking supports only bear negligible axial forces. However, with flexible supports, once the rigid support is lost, all the forces fall on the two side columns and the slewing support structure of the inclined beam. The rotating shaft, bearings, and support base then become structures that must bear both the weight of the support structure itself and external wind and snow loads. Furthermore, because the steel strands are flexible and require pre-tensioning, this structure must also withstand the tensile force from the pre-tensioning of the steel strands. In existing technologies, flexible supports are prone to damage when subjected to external forces from natural environments such as wind and snow loads, requiring frequent maintenance, increasing the intensity of manual labor, and hindering the long-term use of the support. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a flexible tracking bracket side column drive structure that is easy to replace. This structure can maintain stable and good mechanical performance under high pressure and high load conditions and achieve long-term operation.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A flexible tracking bracket side column drive structure that is easy to replace includes a support base. A rotary driver and a first bearing housing are fixedly installed on the support base. A first flange is connected to the power output end of the rotary driver near the first bearing housing. The first flange and a second flange are fixedly connected. The other side of the second flange is fixed to one end face of a first rotating shaft. The first rotating shaft passes through the first bearing housing and is fixed to an inclined beam frame. A second bearing housing assembly is fixedly installed on the side of the support base away from the first bearing housing. The second bearing housing assembly is connected to the inner side of the inclined beam frame.

[0005] The following are further optimizations of the above technical solution by this utility model: The second bearing housing assembly includes two support plates fixedly mounted on a support base. Each support plate has a tension hole. A support plate is provided between the two support plates. A tensioning support plate with a U-shaped groove is fixedly connected to the support plate. The two support plates, the tensioning support plate, and the support plate form a semi-enclosed bearing housing.

[0006] Further optimization: The bearing housing is equipped with a bearing, which is placed on a support plate. The part of the bearing near the inclined beam frame protrudes outside the bearing housing and abuts against the inner wall of the inclined beam frame. A fixing component is also fixedly installed above the bearing.

[0007] Further optimization: A second rotating shaft is fixedly connected to the inner side of the inclined beam frame near the second bearing seat assembly, and the other end of the second rotating shaft passes through the bearing and is connected to a third flange.

[0008] Further optimization: A fourth flange is fixedly connected to the power output end of the rotary drive near the third flange, and the fourth flange is fixedly connected to the third flange by bolts.

[0009] Further optimization: The first flange and the second flange are connected by pins, and a gap is left between the first flange and the second flange.

[0010] Further optimization: The second bearing housing assembly includes two support plates fixedly mounted on the support base. A first connecting plate is provided on one side of the support plate near the inner wall of the inclined beam frame, and a bearing is fixedly connected to the other side of the first connecting plate.

[0011] Further optimization: A second connecting plate is provided on the inner side of the inclined beam frame near the second bearing seat assembly, and the other side of the second connecting plate is connected to the bearing.

[0012] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. The first bearing seat can provide axial and radial support force to the inclined beam frame. When the second bearing seat assembly is made of high molecular weight polyethylene bearing, the second bearing seat assembly can provide axial and radial support force to the inclined beam frame and improve the load capacity together with the first bearing seat. It can withstand external forces brought by natural environment such as wind load and snow load. When the second bearing seat assembly is made of thrust bearing, it can provide axial support force, realize synchronous axial and radial load bearing, and improve the convenience of inspection and maintenance of the tracking bracket.

[0016] Example 1: like Figure 1-4 As shown: A flexible tracking bracket side column drive structure that is easy to replace includes a support base 1. A rotary driver 3 and a first bearing seat 4 are fixedly installed on the support base 1. A first flange 31 is connected to the power output end of the rotary driver 3 near the first bearing seat 4. The first flange 31 and a second flange 51 are fixedly connected. The other side of the second flange 51 is fixed to one end face of a first rotating shaft 5. The first rotating shaft 5 passes through the first bearing seat 4 and is fixed to the inclined beam frame 6. A second bearing seat assembly 7 is fixedly installed on the side of the support base 1 away from the first bearing seat 4. The second bearing seat assembly 7 is connected to the inner side of the inclined beam frame 6.

[0017] In this embodiment, the rotary drive 3 has two power output terminals.

[0018] Two flexible steel cable anchors 61 are provided on the longer side frame of the inclined beam frame 6. Each flexible steel cable anchor 61 is connected to a steel cable 62. The steel cable 62 passes through the shorter side frame of the inclined beam frame 6 and extends to the outside of the inclined beam frame 6.

[0019] In this embodiment, photovoltaic panels 8 are installed on the two steel cables 62.

[0020] The second bearing housing assembly includes two support plates 71 fixedly mounted on the support base 1. Each support plate 71 has a tension hole 76. A support plate 72 is provided between the two support plates 71. A tensioning support plate 73 with a U-shaped groove is fixedly connected to the support plate 72. The two support plates 71, the tensioning support plate 73, and the support plate 72 form a semi-enclosed bearing housing.

[0021] This design allows the tension hole 76 to stabilize the support seat 1 when the column 1 is tightened, balance the preload of the steel cable 62, and offset the impact and vibration of wind and snow loads on the overall structure, making it convenient to use.

[0022] The bearing housing contains a bearing 74, which is placed on a support plate 72. The portion of the bearing 74 near the inclined beam frame 6 protrudes outside the bearing housing and abuts against the inner wall of the inclined beam frame 6. A fastener 75 is also fixedly installed above the bearing 74.

[0023] In this embodiment, both the bearing 74 and the bearing in the first bearing housing 4 are sliding bearings, made of high molecular weight polyethylene. The structure of the sliding bearing is either an integral structure with a central hole or an integral structure divided into two halves with arc-shaped grooves, the groove shapes of which are respectively matched with the first rotating shaft 5 and the second rotating shaft 9.

[0024] The polymer bearing is capable of bearing both axial and radial forces. The bearing 74 is abutted against the inner wall of the inclined beam frame 6 and can withstand the tension brought about by the pre-tensioning of the steel cable 62.

[0025] The inclined beam frame 6 is fixedly connected to the inner side of the second bearing seat assembly 7 with a second rotating shaft 9. The other end of the second rotating shaft 9 passes through the bearing 74 and is connected to a third flange 91.

[0026] The rotary drive 3 is fixedly connected to a fourth flange 32 near the power output end of the third flange 91. The fourth flange 32 is fixedly connected to the third flange 91 by bolts.

[0027] In this embodiment, the first flange 31 and the second flange 51 are connected by pins, and a gap is left between the first flange 31 and the second flange 51.

[0028] This design allows for easy disassembly and use of the rotary drive 3 by leaving a gap between the first flange 31 and the second flange 51 connected by the pin.

[0029] When in use, the rotary drive 3 is started. The power output end of the rotary drive 3 drives the first flange 31 and the fourth flange 32 to rotate. Since the first flange 31 and the second flange 51 are fixedly connected, and the fourth flange 32 is fixedly connected to the third flange 91, the first rotating shaft 5 and the second rotating shaft 9 are driven to rotate. The inclined beam frame 6 follows the first rotating shaft 5 and the second rotating shaft 9 to rotate.

[0030] This design allows the bearing 74 to be abutted against the inner wall of the inclined beam frame 6, thus bearing the tension brought about by the pre-tensioning of the steel cable 62; the bearing 74 and the inner wall and end face of the hole of the first bearing seat 4 jointly bear the weight of the photovoltaic panel 8, the inclined beam frame 6, the wind load, and the snow load. When the rotary drive 3 needs to be replaced, the tension support plate 73, bearing 74 and first bearing seat 4 together provide strong axial and radial support to the inclined beam frame 6.

[0031] After the rotary drive 3 is disassembled, the first bearing seat 4 is used to support the inclined beam frame 6 to prevent it from tipping over and to facilitate its use.

[0032] Example 2: like Figure 5-6As shown, the difference between this embodiment and embodiment 1 is that the second bearing housing assembly 7 includes two support plates 71 fixedly installed on the support base 1. A first connecting plate 77 is provided on one side of the support plate 71 near the inner wall of the inclined beam frame 6, and a bearing 74 is fixedly connected to the other side of the first connecting plate 77.

[0033] A second connecting plate 63 is provided on the inner side of the inclined beam frame 6 near the second bearing seat assembly 7, and the other side of the second connecting plate 63 is connected to the bearing 74.

[0034] In this embodiment, the bearing 74 is a thrust bearing, and the rotary drive 3 has only one power output end.

[0035] When in use, start the rotary drive 3. The power output end of the rotary drive 3 drives the first rotating shaft 5 to rotate through the connected first flange 31 and second flange 51. At this time, the first rotating shaft 5 gives the inclined beam frame 6 a rotational force. The inclined beam frame 6 and the bearing 74 are connected by transmission, which can realize the rotation of the entire inclined beam frame 6, making it convenient to use.

[0036] With this design, when the rotary drive 3 needs to be replaced, the first bearing housing 4 provides radial and axial support to the inclined beam frame 6, and the bearing 74 and the first connecting plate 77 together provide axial support to the inclined beam frame 6, which is convenient to use.

[0037] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
