[0002] Flexible photovoltaic support is a new type of flexible support system for supporting photovoltaic modules. It mainly uses steel strands as the main supporting structure, tightens the inclined cables to resist the horizontal tension of the module cables, and adjusts the module angle with high and low columns. It has bendability and plasticity, and can be adjusted and installed according to the needs of the terrain environment, with a span of up to 15-30 meters.

[0003] The flexible photovoltaic support structure system in the existing photovoltaic array generally adopts double-cable support (without additional cables and space trusses) and three-cable support, and applies prestress to the double cables in direct contact with the photovoltaic components to resist the deadweight of the structure and the force under wind and snow conditions. However, due to the use of a flexible cable structure for support, if the span of the flexible photovoltaic support is large, it is very easy to produce large vibrations due to factors such as low structural stiffness, large span deflection and weak wind resistance. Therefore, it is necessary to design a flexible photovoltaic support that can avoid large vibrations. Utility Model Content

[0022] Example

[0023] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0024] like Figure 1-3 As shown, a high-stability flexible photovoltaic bracket comprises a symmetrically arranged triangular support body 1, a connecting cable 1 2, a connecting cable 2 3 and a fixing rod 8 are connected between the triangular support bodies 1, a plurality of photovoltaic modules 11 are arranged on the connecting cable 1 2 and the connecting cable 2 3, a quadrangular pyramid stabilizing cable 5 is arranged below each photovoltaic module 11, and an auxiliary cable 4 is connected to the fixing rod 8 at one end of the quadrangular pyramid stabilizing cable 5, and the auxiliary cable 4 is connected to the fixing rod 8, two fixing rods 8 are arranged, and the two fixing rods 8 are arranged in parallel with the connecting cable 1 2 and the connecting cable 2 3, and the two ends of the auxiliary cable 4 are respectively connected to the two fixing rods 8, so as to improve the connection stability. In order to ensure the stability of connecting cable 1 2 and connecting cable 2 3, auxiliary supporting bodies 6 are arranged between the triangular supporting bodies 1, and cross fixing rods 12 are arranged between the auxiliary supporting bodies 6. Several photovoltaic modules 11 are placed on connecting cable 1 2 and connecting cable 2 3. Firstly, connecting cable 1 2 and connecting cable 2 3 have a larger bearing capacity. Secondly, due to the influence of severe weather such as strong wind, they will vibrate greatly. The auxiliary supporting bodies 6 can share the bearing capacity of connecting cable 1 2 and connecting cable 2 3 and reduce the shaking caused by them. Shaking sensors 10 are arranged on the side walls of photovoltaic modules 11 to monitor the shaking amplitude of photovoltaic modules 11.

[0025] The triangular support body 1 is provided with a tightening assembly and a controller 9. The triangular support body 1 includes a column 101, a column 2 102, and a column 3 103 connected to the column 101 through a pipeline, and the tightening assembly 7 is arranged inside the column 101. The tightening assembly 7 includes a motor 71 arranged at the bottom side of the column 101, the output shaft of the motor 71 is connected to a rotating shaft 72, and the rotating shaft 72 is connected to the top of the column 101 through a bearing 73. Two cable discs 74 are arranged on the rotating shaft 72, and the two cable discs 74 are fixedly connected to the connecting cable 1 2 and the connecting cable 2 3 respectively.

[0026] The quadrangular pyramid stabilizing cable 5 includes a base 52 arranged on the auxiliary cable 4 and four risers 51 arranged on the top of the base 52, two risers 51 are respectively connected to the connecting cable 1 2, and the other two risers 51 are respectively connected to the connecting cable 2 3.

[0027] During specific use, first fix the triangular support body 1 and the auxiliary support body 6, and connect the connecting rope 1 2, the connecting rope 2 3 and the fixing rod 8 between the triangular support body 1, and the middle position of the connecting rope 1 2 and the connecting rope 2 3 is connected to the auxiliary support body 6, and then install the photovoltaic module 11 in sequence, and connect the four-cornered pyramid stabilizing rope 5 under the photovoltaic module 11, connect the auxiliary rope 4 to the base 52, and then connect the two ends of the auxiliary rope 4 to the two fixing rods 8 respectively, and the shaking sensor 10 monitors the shaking degree of the photovoltaic module 11.
