Referring to fig. 1, fig. 2 and fig. 7, a flexible photovoltaic support provided by the present invention will now be described. The flexible photovoltaic support comprises a first support component and a plurality of inhaul cable components 10. The number of the first supporting components is multiple and is arranged at intervals along the first direction. The inhaul cable assembly 10 is sequentially arranged on each first supporting assembly. The cable assemblies 10 are spaced apart in the second direction. The second direction is perpendicular to the first direction. The plurality of photovoltaic modules 20 are arranged on the stay cable modules 10, the flexible photovoltaic support further comprises a connecting cable 30, and the connecting cable 30 is located between the adjacent first support modules, extends along the second direction and connects the stay cable modules 10 into a whole. The flexible photovoltaic support further comprises an elastic member 31 and a second support assembly 40, and the end of the connecting cable 30 is connected with the second support assembly 40 through the elastic member 31.

In summary, the embodiment of the utility model has the following beneficial effects: the flexible photovoltaic support of above-mentioned scheme except possessing splendid photovoltaic module support efficiency, it can also avoid the connecting cable 30 to take place to relax after using a period, promotes flexible photovoltaic support's stability. Specifically, this flexible photovoltaic support includes a plurality of cable assemblies 10 of locating each first supporting component in proper order, is equipped with a plurality of photovoltaic module 20 on this cable assembly 10, so makes photovoltaic module 20 can incline to set up in order to face the sun. Further, the flexible photovoltaic bracket further comprises a connecting cable 30, the connecting cable 30 is positioned between adjacent first support assemblies and can connect the cable assemblies 10 into a whole, and the end of the connecting cable 30 is connected with the second support assembly 40 through an elastic component 31. So when making connecting cable 30 have the trend of relaxing, the loss of connecting cable 30 prestressing force can effectively be reduced to elastic component 31, avoids it to take place to relax, guarantees the intensity to cable assembly 10 bearing, and then promotes flexible photovoltaic support's stability.

In one embodiment, as shown in fig. 7, the flexible photovoltaic support further comprises a connecting member 32, and one end of the elastic member 31 is connected to the connecting cable 30 through the connecting member 32, and the other end is connected to the second support member 40. When the connecting cable 30 has a relaxation tendency due to the arrangement of the elastic component 31, the elastic component 31 can effectively reduce the loss of prestress of the connecting cable 30 and ensure the strength of bearing the weight of the stay cable assembly 10. As shown in fig. 7, the elastic member 31 includes a stretching portion and hook portions located at both sides of the stretching portion, the end of the connecting cable 30 is fixedly provided with a connecting member 32, the connecting member 32 is provided with a connecting rod to facilitate connection with one of the hook portions, and the other hook portion is connected with the second supporting member 40, so that the second supporting member 40 can provide prestress to the connecting cable 30 through the elastic member 31.

In one embodiment, referring to fig. 1 and 2 together, the number of the connecting cables 30 between the adjacent first support assemblies is one or more, and the portions of the cable assembly 10 between the adjacent first support assemblies can be divided unequally. For example, when the number of the connecting cables 30 is one, the connecting cables 30 can divide the portion of the cable assembly 10 located between the adjacent first support assemblies into two unequal portions in the first direction. When the number of the connecting cables 30 is plural, each connecting cable 30 can divide the portion of the cable assembly 10 located between the adjacent first support assemblies into unequal plural portions in the first direction. In this embodiment, the first direction is parallel to the direction indicated by the arrow X shown in fig. 1 and 2, and the second direction is parallel to the direction indicated by the arrow Y shown in fig. 1 and 2. Further, the second support assembly 40 can prestress the connecting cable 30 via the elastic member 31. Therefore, when one of the parts separated by the connecting cable 30 vibrates under the action of dynamic load, the rest parts of the stay cable assembly 10 are limited by the second supporting assembly 40 through the connecting cable 30, so that the rest parts cannot vibrate along with the vibration of the part, further the whole vibration of the structure cannot be caused, and the stability of the flexible photovoltaic support is further improved. The second support member 40 may be a connecting end disposed on a fixed structure such as the ground or a foundation to provide a prestress to the connecting cable 30. Further, in the present embodiment, the second supporting assembly 40 includes an outer pillar 41 and an outer tie rod 42, the end of the connecting cable 30 is disposed on one side of the outer pillar 41 through the elastic member 31, and the outer tie rod 42 is disposed on the other side of the outer pillar 41 to provide a pulling force to the outer pillar 41. Therefore, the prestress provided by the second support assembly 40 to the connecting cable 30 can be transmitted to the connecting cable 30 through the outer upright 41, the prestress is ensured to be consistent with the extending direction of the connecting cable 30, and the stability of the flexible photovoltaic bracket is further improved. As shown in fig. 7, in the present embodiment, the elastic member 31 is a spring, and is connected between the outer post 41 and the connecting cord 30.

Further, the number of the connecting cables 30 between the adjacent first supporting members is (L/16)²Where L is the span of the cable assembly 10 in meters. Wherein, the span of the cable assembly 10 refers to a portion located between adjacent first support assemblies. When the cable assembly 10 is provided with the first support assemblies only on two sides, the cable assembly 10 has a span, and the span is a horizontal distance between the two first support assemblies. When cable assembly 10 is multispan, that is to say in addition to set up first supporting component in cable assembly 10 both sides, cable assembly 10's middle part still sets up at least one first supporting component. Referring to fig. 1 and 2, in the present embodiment, the first support components include two outer support components 50 at two ends of the cable component 10 and two outer support components at two ends of the cable componentThe assembly 60 is supported in at least one of the intermediate portions of the cable assembly 10 to support the intermediate portion of the cable assembly 10. The cable assembly 10 can thus be divided into multiple spans by the outer and

middle support assemblies

50, 60. In this embodiment, the number of the connecting cables 30 located in the same span is one or more, and the span can be divided unequally, so that the frequency of each part of the span divided by the connecting cables 30 is different, and when a certain part vibrates under the action of a dynamic load, the rest part can vibrate under the condition that the frequency is lower than the original frequency, which is beneficial to the stability of the flexible photovoltaic support.

second cross wires

71 and 72 are symmetrically arranged with respect to the second direction, so that the uniformity of the damping ratio rise can be ensured. It is understood that in other embodiments, the positional relationship of the second cross cable 72 to the first cross cable 71 may be otherwise provided or other cross cables may be provided in addition to the first and

second cross cables
