[0017] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the following will be further explained how the utility model is implemented in combination with the drawings and specific embodiments.

[0018] Refer to Figure 1 And Figure 2 The utility model provides a kind of single-layer four-cable flexible photovoltaic support, including four cables 1 and multiple support frames 2;Each support frame 2 includes chassis 3 and cross beam 4, and chassis 3 is rotatably installed above cross beam 4 by pivot 5;Multiple support frames 2 include two end support frames 21 and several intermediate support frames 22;Four cables 1 are parallel to each other, and are perpendicular to the cross beam 4 of each support frame 2;Each cable 1 passes through the cable buckle of the cross beam 4 of intermediate support frame 22, and the two ends of each cable 1 are fixedly installed on the cross beam 4 of two outer end support frames 2.

[0019] Preferably, for any one support frame 2, its pivot 5 is provided with corresponding control box 6, and a motor for controlling the rotation of the corresponding pivot 5 is installed in the control box 6.

[0020] Preferably, a wireless module is also installed in the control box 6, which is used for wireless connection with an external control center to receive control signals, and the motor controls the rotation of the corresponding pivot 5 according to the received control signals.

[0021] Preferably, the light-sensitive sensor, the vibration sensor and the tilt sensor (not shown in the figure) are also mounted on the crossbeam 4 of each support frame 2, for collecting the current illumination angle data, the vibration data and the tilt angle data respectively; and each sensor is electrically connected with the wireless module, and the wireless module is also used for transmitting the sensor data to the external control center.

[0022] It can be understood that each sensor can adopt an existing model, and the light-sensitive sensor should be mounted on the upper surface of the crossbeam 4 of the support frame 2, and the vibration sensor and the tilt sensor can also be mounted on other surfaces. Each sensor cooperates with the wireless module to achieve multiple functions.

[0023] For example, the light-sensitive sensor collects the current illumination angle data, and the wireless module transmits the illumination angle data to the control center, and automatically controls the operation of each motor to make the crossbeams 4 of the support frames 2 rotate synchronously, so that the four steel cables 1 rotate to adjust the angle of the photovoltaic panel, so that the photovoltaic panel faces the illumination direction, and the power generation efficiency is improved; the tilt sensor constantly feeds back the tilt angle of the crossbeam 4 to improve the accuracy of angle adjustment.

[0024] In addition, in abnormal conditions such as windy weather, the support frame 2 may shake violently, and when the vibration data detected by the vibration sensor is greater than the preset threshold, it indicates that there is a greater risk. At this time, the control center can automatically start the preset adjustment program to adjust the windward angle of the photovoltaic panel to reduce the vibration.

[0025] In summary, the single-layer four-cable flexible photovoltaic support provided by the utility model adopts a four-cable structure combined with a support frame structure with a rotatable crossbeam, so that the flexible photovoltaic support can rotate as a whole according to actual needs, which is beneficial to improve the stability and enhance the wind resistance performance; and by cooperating with the control center through the wireless module, the angle of the photovoltaic assembly can be adjusted to track the change of the illumination angle of the sun in real time, thereby improving the power generation efficiency.
