Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to an end structure of a flat single-axis tracking flexible photovoltaic support. Background Technology

[0002] Photovoltaic (PV) mounting systems are support structures used to install photovoltaic (PV) modules in a photovoltaic (PV) power generation system. PV mounting systems can be categorized by angle into fixed tilt, adjustable tilt, adjustable azimuth, and dual-axis adjustable tracking systems. Tracking systems improve power generation efficiency by manually or through a control system adjusting the tilt and azimuth angles of the PV modules. Compared to traditional fixed-tilt rigid PV mounting systems, which require high terrain flatness and a large number of pile foundations, flexible PV mounting systems are increasingly widely used due to their advantages such as large spans, high clearance, and strong adaptability to various terrains.

[0003] In the existing end structure of the tracking flexible support, the rotating beam has no reinforcing bending members and can only rely on its own material properties, which requires high material quality. The drive structure is directly connected to the rotating beam, which can easily cause damage to the drive structure in harsh environments, increasing the cost of later maintenance.

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0036] like Figures 1-6 As shown, an end structure of a single-axis tracking flexible photovoltaic support includes an end column 101, and also includes...

[0037] The pivot beam 102 is rotatably connected to the end column 101;

[0038] The rotating shaft arc disk 103 is fixed to the rotating shaft beam 102 and is located vertically below the rotating shaft beam 102. The end traction mechanism pulls the rotating shaft arc disk 103 to rotate, so that the rotating shaft arc disk 103 and the rotating shaft beam 102 rotate in the vertical plane.

[0039] A reinforcing truss 1040 is provided, with both ends of the reinforcing truss 1040 fixed to the pivot beam 102. Multiple first reinforcing tubes 1041 are provided between the reinforcing truss 1040 and the pivot beam 102.

[0040] The reinforcing truss 1040 can be made of arc-shaped or square reinforcing tubes. The end columns 101 can be made of circular or square columns. The pivot beam 102, pivot arc plate 103, and reinforcing truss 1040 can be formed by circular or square tubes, respectively. The pivot beam 102, pivot arc plate 103, reinforcing truss 1040, and first reinforcing tube 1041 are welded together to form a rotating mechanism. Compared with the conventional design, the addition of pivot arc plate 103 increases the bending resistance of the rotating mechanism, effectively reducing the bending deformation of the pivot beam 102 and lowering the strength requirements of the material used to manufacture the pivot beam 102. The reinforcing truss 1040 and first reinforcing tube 1041 added in this invention can effectively reduce the bending deformation caused by the horizontal force applied to the pivot beam 102 by the load-bearing cable 105.

[0041] Specifically, in one alternative implementation, such as Figure 2 As shown, the flexible photovoltaic support includes four load-bearing cables 105 divided into two groups, each group of load-bearing cables 105 is used to install a single row of photovoltaic modules; four load-bearing cable installation ports are reserved on the rotating beam 102;

[0042] The two load-bearing cables 105 located inside pass through the reinforcing truss 1040 and the pivot beam 102 and are then fixedly connected to the pivot beam 102 by anchors.

[0043] The load-bearing cable 105 located at the edge passes through the pivot beam 102 and is fixedly connected to the pivot beam 102 by anchors.

[0044] Specifically, in one alternative implementation, such as Figure 3 As shown, the end traction mechanism includes front and rear traction ropes 1065 and 1066. Front and rear traction wheel supports 1061 and 1062 are fixedly mounted on the front and rear sides of the end column 101, respectively. Front and rear traction wheels 1063 and 1064 are respectively mounted on the front and rear traction wheel supports 1061 and 1062.

[0045] A drive wheel support 1071 is installed on the side of the end column 101. A drive wheel 1072 is installed on the drive wheel support 1071. A transverse drive cable 1070 is inserted into the drive wheel 1072. When the drive wheel 1072 rotates, the transverse drive cable 1070 located in front of and behind the drive wheel 1072 moves in opposite directions in the transverse direction.

[0046] One end of the front and rear traction ropes 1065 and 1066 are respectively connected to the transverse drive cables 1070 on both sides of the drive wheel 1072. The other end of the front traction rope 1065 is connected to the rotating shaft arc disk 103, and the front traction rope 1065 is in contact with the front traction wheel 1063. The other end of the rear traction rope 1066 is connected to the rotating shaft arc disk 103, and the rear traction rope 1066 is in contact with the rear traction wheel 1064.

[0047] Specifically, in one optional embodiment, the other end of the front traction rope 1065 is attached to a traction rope buckle fixed on the rotating shaft arc plate 103; the other end of the rear traction rope 1066 is attached to a traction rope buckle fixed on the rotating shaft arc plate 103.

[0048] Specifically, in one optional embodiment, the lateral drive cable 1070 is connected to the drive wheel 1072 in the following ways: the ends of the lateral drive cables 1070 located on both sides of the drive wheel 1072 are connected and embedded in the wheel groove of the drive wheel 1072; or, the lateral drive cables 1070 located on both sides of the drive wheel 1072 are respectively tied to the drive cable buckles fixed on both sides of the drive wheel 1072.

[0049] Specifically, in one optional embodiment, the front and rear traction wheel supports 1061 and 1062 are installed downwardly on the front and rear sides of the end column 101.

[0050] The drive structure of this utility model is formed by a transverse drive cable 1070, a front traction rope 1065, and a rear traction rope 1066. The rotating shaft arc disk 103 and the transverse drive cable 1070 are connected by the front traction rope 1065 and the rear traction rope 1066. The ends of the front traction rope 1065 and the rear traction rope 1066 are fixed to the transverse drive cable 1070. When the transverse drive cable 1070 moves, it drives the front traction rope 1065 and the rear traction rope 1066 to move, thereby realizing the rotation of the rotating mechanism. The driving mechanism of this invention involves a transverse drive cable 1070 driving a front traction rope 1065 and a rear traction rope 1066. For example, the front traction rope 1065 pulls the rotating axle disk 103 forward, or the rear traction rope 1066 pulls the rotating axle disk 103 backward, causing the rotating axle disk 103 to rotate clockwise or counterclockwise in the vertical plane. This causes the rotating axle beam 102 to rotate clockwise or counterclockwise around the end column 101 in the vertical plane. The load-bearing cable 105 moves synchronously with the rotating axle beam 102, thus changing the tilt angle of the photovoltaic module mounted on the load-bearing cable 105, achieving tracking of the photovoltaic module. Using this driving structure, external environmental changes are less likely to significantly affect the driving structure, and subsequent maintenance is simple and low-cost.

[0051] Specifically, in one alternative implementation, such as Figure 4 As shown, the rotating shaft beam 102 is rotatably connected to the end column 101 in the following manner:

[0052] A box support 1080 is mounted on the upper part of the end column 101. The spherical base 1081 of the bearing box is connected to the box support 1080 by bolts. The movable spherical head 1082 in the bearing box relative to the spherical base 1081 is fixed to the rotating beam 102 by a connecting shaft. The end column 101 and the rotating beam 102 are connected by bearings, allowing the rotating beam 102 to rotate relative to the end column 101.

[0053] Specifically, in one alternative implementation, such as Figure 6 As shown, the two edges of the rotating shaft arc plate 103 and the rotating shaft beam 102 are respectively connected by a second reinforcing tube 1042 and a fifth reinforcing tube 1045. The middle part of the rotating shaft arc plate 103 and the rotating shaft beam 102 is connected by a third reinforcing tube 1043 and a fourth reinforcing tube 1044. The second reinforcing tube 1042, the third reinforcing tube 1043, and the rotating shaft beam 102 form a triangle, and the fourth reinforcing tube 1044, the fifth reinforcing tube 1045, and the rotating shaft beam 102 also form a triangle. By setting this type of reinforcement structure, the relationship between the rotating shaft arc plate 103 and the rotating shaft beam 102 is more stable, and the rotating shaft beam 102 is less likely to be deformed by the load-bearing cable 105.

[0054] Specifically, in one alternative implementation, such as Figure 6As shown, the rotating shaft arc plate 103 and the rotating shaft beam 102 are also connected by at least one sixth reinforcing pipe 1046. Furthermore, by setting this type of reinforcing structure, the relationship between the rotating shaft arc plate 103 and the rotating shaft beam 102 is more stable, and the rotating shaft beam 102 is less likely to be pulled and deformed by the load-bearing cable 105.

[0055] Specifically, in one alternative implementation, such as Figure 6 As shown, the end structure of the flat single-axis tracking flexible photovoltaic bracket also includes four inclined bases. The front and rear sides of the end column 101 are respectively fixed with front and rear upper inclined supports 1091 and 1092, and the front and rear sides of the end column 101 are respectively fixed with front and rear lower inclined supports 1093 and 1094; the front and rear lower inclined supports 1093 and 1094 are fixed below the front and rear upper inclined supports 1091 and 1092.

[0056] One end of the two stay cables located at the edge is connected to the front and rear upper stay supports 1091 and 1092 respectively via compression anchors, and the other end of the two stay cables located at the edge is connected to the two stay bases located at the edge respectively.

[0057] One end of each of the two internal stay cables is connected to the front and rear lower stay supports 1093 and 1094 respectively via compression anchors, and the other end of each of the two internal stay cables is connected to the two internal stay bases respectively. The end column 101 uses four stay cables, arranged in two layers, with two cables in each layer, and is connected to the stay bases using anchors to reduce the horizontal force indirectly applied to the end column 101 by the load-bearing cable 105.

[0058] The above description is only a specific embodiment of the present utility model. Various examples and illustrations do not constitute a limitation on the substantive content of the present utility model. Those skilled in the art can modify or transform the above-described specific embodiments after reading the description without departing from the essence and scope of the utility model.
