Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic power generation, in particular to a tracking flexible photovoltaic support structure. BACKGROUND

[0002] With the increasing demand for clean energy worldwide, photovoltaic power generation, as a sustainable way to obtain energy, has developed rapidly. Most traditional photovoltaic power stations are built in flat land areas, however, as available land resources become scarce and the demand for energy utilization efficiency continues to increase, the construction site of photovoltaic power stations has begun to diversify. In addition to the common land, building roofs, fish ponds, sewage treatment plants, agricultural greenhouses and complex mountainous areas have become potential application areas for photovoltaic power generation. This diversified application scenario not only makes full use of idle land, but also helps to improve the comprehensive utilization efficiency of land resources and reduce the dependence on limited land resources.

[0003] The steel beam photovoltaic support widely used in the current market belongs to a rigid structure, which is difficult to adapt to complex terrain such as mountains and other non-flat areas. In addition, the structural span of the steel beam support is limited, and a large amount of steel is required, which not only increases the construction cost, but also is not conducive to environmental sustainable development. In contrast, flexible photovoltaic supports have stronger terrain adaptability and are more suitable for popularization and application in complex mountainous areas and other variable terrains.

[0004] Flexible photovoltaic supports can effectively improve the adaptability to complex terrain, and tracking photovoltaic support structures can improve the power generation of photovoltaic panels. If the two are combined, the tracking photovoltaic support can be applied to a wider area. Therefore, how to combine the advantages of the two and develop a photovoltaic support structure with high power generation and strong terrain adaptability has become a problem that needs to be solved at present.

DETAILED DESCRIPTION

[0036] In order for those skilled in the art to better understand the technical solutions of the present application, the preferred embodiments of the present application are described below in combination with specific embodiments, but it should be understood that the drawings are only used for illustrative description and cannot be understood as a limitation on the present application; in order to better illustrate the embodiments, some components in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size; for those skilled in the art, it is understandable that some well-known structures in the drawings and their descriptions may be omitted. The positional relationship described in the drawings is only used for illustrative description and cannot be understood as a limitation on the present application.

[0037] The present application is further described below in combination with the drawings and embodiments, but it is not used as a basis for limiting the present application.

[0038] As Figures 1 to 7As shown, a tracking flexible photovoltaic support structure includes two first columns 12 arranged at two ends of the support structure respectively, each first column 12 is provided with a first cross beam 112, the first column 12 and the first cross beam 112 are connected through a first rotating part 111; at least one second column 22 is arranged between the two first columns 12, each second column 22 is provided with a second cross beam 212, the second column 22 and the second cross beam 212 are connected through a second rotating part 211; a steel cable 80, both ends of the steel cable 80 are fixedly connected to two first cross beams 112 respectively, and pass through the second cross beam 212 located therebetween.

[0039] The first cross beam 112 and the second cross beam 212 are both provided with a transmission plate 40, adjacent two transmission plates 40 are connected through a transmission rod structure, and the transmission rod structure is connected with a driving device 90.

[0040] The driving device 90 drives the transmission plate 40 connected thereto to rotate through the transmission rod structure, and then drives the first cross beam 112 structure or the second cross beam 212 structure to rotate with the corresponding first rotating part 111 or second rotating part 211 as the rotating shaft.

[0041] The first rotating part 111 includes a boss connecting section 1111 and a rotating shaft section 1112 fixed with the boss connecting section 1111, the rotating shaft section 1112 passes through the first column 12 and the first cross beam 112, and is rotationally connected with the first column 12 and the first cross beam 112 structure, and the boss connecting section 1111 is in abutting fit with the outer side of the first column 12.

[0042] The boss connecting section 1111 of the first rotating part 111 and the outer side of the first cross beam 112 connected therewith are connected with a first zipper 113, the first zipper 113 is configured to be adjustable in length, and the length of the first zipper 113 can be adjusted according to the installation condition of the steel cable 80, so that the installation is more convenient.

[0043] The first zipper 113 is provided in two, and the two first zippers 113 are symmetrically arranged relative to the rotating axis of the first cross beam 112, so that the stress on the left and right sides of the first cross beam 112 can be balanced, and the first cross beam 112 is uniformly stressed.

[0044] In the prior art, in order to adapt to complex installation terrain, a steel cable can be pulled through a column, and a photovoltaic panel is fixed on the steel cable to adapt to different terrains for installing the photovoltaic panel. After the photovoltaic panel is installed, the cross beam fixing the steel cable bears a large tensile stress of the steel cable, resulting in that the cross beam bears a large bending moment.

[0045] In the embodiment, the first cross beam 112 is subjected to tensile stress of the steel cable 80, resulting in that it receives a large bending moment. By arranging the first pull lock 113, the bending moment applied to the first cross beam 112 by the steel cable 80 can be balanced, and the first cross beam 112 is balanced in force. At the same time, the first transmission member 111, the first cross beam 112 and the first pull lock 113 form an integral structure. If the first cross beam 112 deflects or rotates about the rotation axis, the first stand column 12 will not be subjected to additional force, and the stress of the first stand column 12 can be simplified. It can be seen that when the first cross beam 112 deflects under the action of strong wind or the first cross beam 112 rotates to adjust the angle of the photovoltaic panel 70, the first stand column 12 will not be subjected to additional force, and the stress of the first stand column 12 can be simplified.

[0046] Corresponding second cross beams 212 are arranged on both sides of the second stand column 22, and the steel cable 80 passes through the two second cross beams 212 in sequence. The two second cross beams 212 are connected by a cross beam fastener 213, and the two ends of the cross beam fastener 213 are respectively abutted and fixed with the second cross beams 212. By arranging the cross beam fastener 213, the two second cross beams 212 can be fixed, so that the two second cross beams 212 rotate as a whole. The mutual misalignment of the two second cross beams 212 can be prevented, the shaking of the steel cable 80 can be reduced, and the photovoltaic panel 70 is more stable.

[0047] In the embodiment, the cross beam fastener 213 can include a screw rod and a nut. The screw rod can pass through the two second cross beams 212 in sequence, and then the two ends of the screw rod are connected with the two nuts respectively. The two nuts clamp the two second cross beams 212, so that the two second cross beams 212 are relatively fixed.

[0048] The second cross beam 212 is provided with a rope fastener 214. The rope fastener 214 is fixed with the steel cable 80 and abuts with the second cross beam 212 in the axial direction of the steel cable 80. The rope fastener 214 abuts on the side of the second cross beam 212 away from the second stand column 22. The rope fastener 214 can prevent the axial movement between the steel cable 80 and the second cross beam 212, so that the position of the photovoltaic panel 70 remains fixed.

[0049] The transmission rod structure includes a transmission shaft 54, a connecting rod 52 and a universal joint 53. The transmission shaft 54 is arranged on the first stand column 12 and the second stand column 22, and is rotationally connected with the corresponding transmission plate 40 on the first stand column 12 or the second stand column 22. The transmission shaft 54 on the second stand column 22 is connected with the driving device 90. The adjacent two transmission shafts 54 are connected by the connecting rod 52.

[0050] In the photovoltaic support structure, each two columns constitute a span, the number of the second columns 22 is odd, i.e. 1, 3, 5, etc., therefore, the number of the spans is also even, so as to realize the structural stability and the arrangement symmetry. In the embodiment, the photovoltaic support structure is arranged as two spans, the driving motor is arranged on the second column 22, and the driving device 90 can be the driving motor, and the output end of the driving motor is connected with the transmission shaft 54.

[0051] The connecting rod 52 and the transmission shaft 54 are connected through the universal joint 53, so that the power transmission of the adjacent two transmission shafts 54 can be realized through the universal joint 53 and the connecting rod 52.

[0052] In the embodiment, the transmission device 51 for mounting the transmission shaft 54 is arranged on the first column 12.

[0053] The transmission plate 40 is arranged as a semicircular plate and is arranged on the lower side of the first cross beam 112 or the second cross beam 212, so that the photovoltaic panel 70 can be avoided to be shielded. At the same time, since the photovoltaic panel 70 is arranged on the upper side, the illumination and the rain erosion of the transmission rod structure and the driving device can be reduced, and the service life can be prolonged, and the corresponding arc-shaped rack 41 is arranged on the arc-shaped edge, the arc-shaped rack 41 is matched with the transmission shaft 54, i.e. the arc-shaped rack 41 is meshed and connected with the transmission shaft 54, so as to realize the position keeping after the first cross beam 112 and the second cross beam 212 are adjusted to the preset inclination angle.

[0054] The second zipper 60 is fixedly connected between the first column 12 and the ground. The boss connecting section 1111 gives the inward pulling force (i.e. the pulling force towards the side of the photovoltaic panel 70) to the first column 12, and the second zipper 60 gives the outward pulling force (i.e. the pulling force away from the side of the photovoltaic panel 70) to the first column 12, so as to balance the stress of the first column 12.
