By adopting the technical scheme, the light Fu Rouxing bracket is in a stable state when not subjected to external force; when the downward force is applied, the bearing cable shares the force applied by the horizontal cable through the triangular stabilizing frame, the tension of the bearing cable is counteracted with the external force, the stability of the horizontal cable is ensured, and the deformation of the photovoltaic cell panel on the horizontal cable is prevented; when the photovoltaic support is subjected to upward force, the tension of the flexible stabilizing rope is counteracted with the upward force, so that the photovoltaic support can resist wind load from below. Under the action of wind lifting load, the rigid support frame is stressed by the flexible stabilizing rope obliquely upwards, and the stay cable applies obliquely downwards force to the rigid support frame for a long time for fixing, so that the joint of the rigid support frame is easy to deform, and even the whole rigid support frame is likely to deflect. By adding the stable inhaul cable, the tension of the stable inhaul cable is offset with the force applied to the inner upper part of the joint of the steel columns by the flexible stable inhaul cable, so that the stress balance of the joint of the steel columns is kept, and the stability of the horizontal inhaul cable is ensured.
Further, the light Fu Rouxing support with bidirectional bearing rigidity further comprises a tuning mass damper connected to the middle of the bearing cable, and the tuning mass damper is used for balancing vibration and stabilizing the horizontal inhaul cable when the photovoltaic flexible support vibrates in a small amplitude.

Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings and examples.
The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
Referring to fig. 1, the embodiment comprises a rigid support frame 1, a horizontal stay cable 2, a stay cable 3, a triangular stabilizer 5, a bearing cable 6, a flexible stabilizer cable 7, a stabilizer cable 8 and a tuning mass damper 9, wherein the rigid support frame 1 comprises a steel beam 11 and a steel column 12. One end of the steel column 12 is fixed on the installation ground, the other end is vertically fixed with the middle part of the steel beam 11, and the steel beams 11 of the two rigid support frames 1 are mutually parallel on the same horizontal plane. One end of each of the two stay cables 3 is connected with the upper part of the steel column 12, and the other end is fixed on the installation ground outside the two rigid support frames 1. The horizontal inhaul cables 2 are arranged between the steel beams 11 and used for bearing the photovoltaic cell panels 4, the triangular stabilizing frames 5 are arranged below the horizontal inhaul cables 2, and the bearing cables 6 are connected between the steel beams 11 and the angular points of the sagging of the triangular stabilizing frames 5 in a segmented mode. The flexible stabilizing rope 7 is respectively connected with the sagging corner point of the triangular stabilizing frame 5 and the lower part of the steel column 12. The connection point of the flexible stabilizing rope 7 and the steel column 12 is connected with the fixed point of the same-side inclined stay rope 3 on the installation ground through the stabilizing stay rope 8. The tuning mass damper 9 is installed in the middle of the load-bearing cable 6, and adopts a damper, and comprises a connecting piece 91 connected to the load-bearing cable 6 through a preformed armor rod 94, a steel strand 92 fixedly connected to the connecting piece 91, and heavy weights 93 connected to two ends of the steel strand 92. The vibration damper is of a symmetrical structure as a whole.
In the installation of the embodiment, two installation sequences can be adopted, wherein the first installation sequence is that the rigid support frame 1, the stay cable 3, the horizontal cable 2, the photovoltaic cell panel 4, the triangular stabilizer 5, the damper, the bearing cable 6, the flexible stabilizing cable 7 and the stabilizing cable 8, and in the process, the horizontal cable 2 is slidably installed on the photovoltaic cell panel 4 after the installation and the application of the pretightening force, so that the horizontal cable can sag and deform under the action of the gravity of the photovoltaic cell panel 4, and relatively large pretightening force is required to be applied when the bearing cable 6 is installed subsequently, so that the horizontal cable 2 is jacked up to the horizontal position again. Before the flexible stabilizing rope 7 is installed, the whole body is in a balanced state, a pretightening force is not required to be applied when the flexible stabilizing rope 7 and the stabilizing guy rope 8 are installed, and the flexible stabilizing rope is in an unrelaxed state. The installation of the photovoltaic cell panel 4 can be more convenient by adopting the sequential installation.
The second installation sequence is that the rigid support frame 1- & gt the stay cable 3- & gt the horizontal cable 2- & gt the triangular stabilizer 5- & gt the damper- & gt the bearing cable 6- & gt the photovoltaic cell panel 4- & gt the flexible stabilizing cable 7- & gt the stabilizing cable 8, wherein the photovoltaic cell panel 4 is installed after the horizontal cable 2 and the bearing cable 6 are integrally installed and tensioned, so that when the bearing cable 6 is installed, pretightening force is required to be applied, the horizontal cable 2 is arched to be more than the horizontal position through the support of the triangular stabilizer 5, so that after the photovoltaic cell panel 4 is installed, the gravity of the horizontal cable is balanced with the supporting force provided by the bearing cable 6 through the triangular stabilizer 5, and the horizontal cable 2 is pressed back to the horizontal position again, so that the whole photovoltaic cell panel is in a stable state, and the pretightening force is not required to be applied when the flexible stabilizing cable 7 and the stabilizing cable 8 are installed. The advantage of this sequence is that the horizontal guy wires 2 and the load-bearing wires 6 need to exert relatively little pre-tension.
When the embodiment is stressed, the bearing cable 6 provides upward supporting force through the triangular stabilizer 5, the flexible stabilizer cable 7 provides downward pulling force through the triangular stabilizer 5, the horizontal guy cable 2 can be prevented from vibrating with larger amplitude, when the vibration with smaller amplitude occurs, the damper generates movement opposite to the vibration phase of the photovoltaic flexible support due to inertia of mass, the two ends of the short and thick steel strands 92 are continuously bent up and down, friction work is generated between the steel strands 92, vibration energy is eliminated, the stability of the horizontal guy cable 2 is maintained, and the photovoltaic cell panel 4 is prevented from being damaged due to the vibration of the photovoltaic flexible support.
In this embodiment, the pretightening force is not applied when the flexible stabilizing rope 7 and the stabilizing inhaul cable 8 are installed, so that the whole stability is not influenced when the flexible stabilizing rope 7 and the stabilizing inhaul cable 8 are replaced, and under the action of the flexible stabilizing rope 7 and the stabilizing inhaul cable 8, the damper is taken down for a short time to replace, so that the whole stability is not greatly influenced, and the maintenance of the photovoltaic flexible support and the replacement of a wear-and-tear part are more convenient.
The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
