[0002] The present application relates to the technical field of photovoltaic devices, in particular to a photovoltaic support and a flexible tracking photovoltaic system. BACKGROUND

[0003] In the field of photovoltaic devices, photovoltaic tracking supports can support, fix and rotate photovoltaic modules, thereby achieving better power generation efficiency by better receiving light. The current photovoltaic tracking supports are mostly driven by motors combined with rotary reducers to rotate the main shaft, which in turn drives the photovoltaic modules on the main shaft to track the sun in real time. The above structure needs to rotate the main shaft synchronously with the photovoltaic modules, and the motor needs to be supported by a stable foundation structure and have a large power output. Therefore, the motor is mostly used in photovoltaic support structures that are directly set on the ground or have a small span. For photovoltaic module setting scenes with complex terrain and large span, more upright columns need to be set for support, and a main shaft with a large cross-sectional size needs to be used to achieve support and rotation. This not only has a high cost, but also cannot meet the setting requirements of the support in some complex mountainous environments due to the small span of the structure, which makes it difficult for the photovoltaic support to achieve high-efficiency power generation of the photovoltaic modules.

DETAILED DESCRIPTION

[0036] The core of the present invention is to disclose a photovoltaic bracket to improve the adaptability of the photovoltaic bracket in complex environments and meet the efficient power generation needs of photovoltaic components.

[0037] Another core of the present application is to provide a flexible tracking photovoltaic system comprising the above photovoltaic support.

[0038] In order to make the person skilled in the art better understand the present application, the following refers to the drawings of the present application, and the following embodiments shown in the following are not limited to the content of the invention claimed in the claims. In addition, the entire content of the following embodiments is not limited to the solution of the invention claimed in the claims.

[0039] As shown in the following Figures 1-5 The photovoltaic support provided by the embodiment of the present application mainly comprises end columns 740, main cables 710, wind-resistant cables 750 and wind-resistant frames 760, wherein the end columns 740 serve as the basic load-bearing structure of the photovoltaic support, and are arranged in two groups at both ends of the area where the photovoltaic panel assembly 720 is required to be arranged. Each group of end columns 740 can include two or more column structures to arrange multiple main cables 710. It should be noted that for some ground structures, the end columns 740 have poor setting stability, and some main cables 710 have large span areas and strong tension requirements. In this case, the end columns 740 can also be connected to the ground through a cable-stayed cable to enhance the connection force point position of the end columns 740 to the ground, thereby improving the setting stability of the end columns 740.

[0040] The two ends of the main cable 710 are pulled and fixed by the end column 740, and two adjacent main cables 710 are arranged in parallel to provide a mounting platform. In particular, a plurality of rotating nodes 730 are arranged at intervals on the two main cables 710. Part of the structure of the rotating node 730 is fixedly connected to the main cable 710, and the other part of the structure can rotate relative to the main cable 710. The movement area on the rotating node 730 is used to carry the photovoltaic panel assembly 720, thereby driving the photovoltaic panel assembly 720 to rotate based on the main cable 710, and achieving the tracking effect of the photovoltaic panel assembly 720 on sunlight.

[0041] In order to ensure the support stability of the photovoltaic support provided by the above embodiment for the photovoltaic panel assembly 720, the photovoltaic support further comprises wind-resistant cables 750 and wind-resistant frames 760. The wind-resistant cables 750 are arranged in the length direction of the main cable 710 and pass through part or all of the area of the main cable 710. At the same time, the wind-resistant cables 750 are connected to the main cable 710 through a plurality of wind-resistant frames 760 to form an integrated structure, so that the integrated structure of the main cable 710 and the wind-resistant cable 750 has stronger structural stability and can resist larger wind conditions.

[0042] Further, in order to improve the structural reinforcement effect of the wind-resistant cable 750 on the main cable 710, in some embodiments of the present application, the wind-resistant cable 750 is arranged on the symmetry plane between two adjacent main cables 710. It should be noted that the symmetry plane is a plane that is located between the two main cables 710, perpendicular to the two main cables 710, and equal in distance to the two main cables 710. Correspondingly, the wind-resistant frame 760 is preferably arranged in a stable triangular or trapezoidal structure. For example, in a triangular structure, two main cables 710 and a single wind-resistant cable 750 are fixedly arranged at the three vertices of the triangular structure of the wind-resistant frame 760 to meet the structural reinforcement and wind resistance requirements of the main cable 710.

[0043] It should be noted that the photovoltaic support provided by the embodiments of the present application has a large-span support requirement. In this working condition, the two end columns 740 cannot meet the structural support requirements of the main cable 710, which may cause the main cable 710 to sag. Therefore, in some embodiments of the present application, a plurality of intermediate columns 770 are arranged between the two groups of end columns 740. The number of intermediate columns 770 can be appropriately increased according to the span between the two groups of end columns 740. Meanwhile, the intermediate columns 770 are arranged on the path of the main cable 710 and are fixedly connected to the main cable 710 to support the main cable 710 and improve the tension stability of the main cable 710.

[0044] Based on the above embodiments, a plurality of wind-resistant frames 760 can be arranged between a single group of end columns 740 and intermediate columns 770, i.e., between one span. It should be noted that the wind-resistant frame 760 arranged at the middle of the single group of end columns 740 and intermediate columns 770 has a larger vertical dimension than the wind-resistant frames 760 arranged at other positions. The wind-resistant cable 750 is not in a taut state in the length direction and has an up-and-down fluctuation. As shown in FIG. 7, the middle of the wind-resistant cable 750 between the end column 740 and the intermediate column 770 is the lowest point structure. The flexible wind-resistant cable 750 can dissipate wind energy by swinging in a working condition with strong wind, thereby improving the wind resistance performance. Figure 1

[0045] Further, in the photovoltaic support provided by the embodiments of the present application, the rotating joint 730 is arranged on the main cable 710 to realize the rotation of the photovoltaic panel assembly 720 based on the main cable 710, thereby meeting the real-time tracking of sunlight by the photovoltaic panel assembly 720 and improving the power generation efficiency of the flexible tracking photovoltaic system.

[0046] ​Specifically, the rotating node 730 mainly includes a fixed part 10, a rotating part 20, a driving part 30 and a supporting part 40, wherein the fixed part 10 is a rigid structure and is fixedly arranged on the main cable 710 through a locking part 50 to provide a basic bearing structure for other parts of the rotating node 730. The locking part 50 is arranged one-to-one with the main cable 710, and one-to-one here specifically means that each main cable 710 corresponds to one locking part 50. In some embodiments, the main cable 710 is usually arranged in two parallel parts, which are tensioned by two end columns, and correspondingly, for a single rotating node 730, the fixed part 10 is fixedly connected with the main cable 710 through two locking parts 50. The two-point stationary point fixed mode can make the fixed part 10 maintain a stable structural arrangement state on the main cable 710.

[0047] In the above structure, as shown in Figures 6-9 The locking part 50 can be a single U-shaped bolt 520, which is arranged through a structural beam on the fixed part 10 to form a connecting hole structure between the closed end of the U-shaped bolt 520 and the side wall of the structural beam, the connecting hole structure is used for the main cable 710 to pass through, and then the main cable 710 is pressed to the side wall of the structural beam by tightening the U-shaped bolt 520 to make the closed end of the U-shaped bolt 520 contact the main cable 710, and the structural beam is fixedly arranged on the main cable 710 by tightening the nut on the U-shaped bolt 520. Further, considering that the main cable 710 directly contacts the structural beam on the fixed part 10, there is a great risk of surface wear, therefore, in some embodiments of the present application, the locking part 50 specifically includes a U-shaped bolt 520 and a support 510 used in cooperation with the U-shaped bolt 520. Specifically, the support 510 includes a groove structure formed by four legs, and the bottom structure of the groove is an arc surface. The U-shaped bolt 520 passes through both sides of the support 510 and is fixedly connected with the structural beam on the fixed part 10. On this basis, the main cable 710 can be placed inside the groove on the support 510 to be connected with the groove through the arc surface structure. At the same time, the closed end of the U-shaped bolt 520 is also a curved arc surface structure. When the U-shaped bolt 520 presses the main cable 710 to the groove position of the support 510, the circumferential direction of the main cable 710 is in contact with the arc surface, which can reduce the wear risk of the main cable 710. It should be noted that the groove structure formed by the legs of the support 510 can limit the main cable 710 after being placed, so as to avoid affecting the arrangement stability of the fixed part 10 due to excessive shaking of the main cable 710.

[0048] It should be noted that the above structure is to simplify the structural complexity of the rotating node 730 on the basis of maintaining the functional effect of the rotating node 730. Similarly, the fixed part 10 and the single main cable 710 can also be fixed by two or more locking components 50. The two or more locking components 50 are arranged at intervals in the length direction of the main cable 710 to improve the structural stability of the fixed part 10 through multi-point connection.

[0049] On this basis, the rotating part 20 is rotatably connected with the fixed part 10. Here, the rotatable connection means that the rotating part 20 can rotate relative to the fixed part 10 and the main cable 710. The specific rotation is realized by the driving part 30. The driving part 30 is arranged on the fixed part 10 and is in transmission connection with the rotating part 20. The driving part 30 is used to output power and drive the rotating part 20 to rotate relative to the fixed part 10 based on the fixed part 10.

[0050] It should be noted that the driving part 30 can be fixedly arranged on the fixed part 10 so that one end thereof is arranged relatively stationary with the main cable 710. Meanwhile, the driving part 30 can include an oscillating rod. The driving part 30 drives the oscillating rod to oscillate based on a preset point through electric or hydraulic action. The action end of the oscillating rod is fixedly connected with the rotating part 20. The oscillating rod can drive the rotating part 20 to rotate relative to the fixed part 10 in the oscillating process. The clockwise and counterclockwise rotation actions of the rotating part 20 are realized by setting the oscillating direction of the oscillating rod. Thus, the rotating node 730 has the rotating driving effect on the photovoltaic panel assembly 720.

[0051] Similarly, the driving part 30 can also be a structure in which two ends thereof are hingedly connected with the fixed part 10 and the rotating part 20, respectively. On this basis, the driving part 30 adjusts its own length, and the fixed part 10 is fixed relative to the position of the main cable 710. The other end of the driving part 30 applies a force to the rotating part 20. Thus, the clockwise and counterclockwise movements of the rotating part 20 relative to the fixed part 10 are realized through the elongation and shortening actions.

[0052] Further, the supporting part 40 is arranged on the rotating part 20 as a structure directly connected with the photovoltaic panel assembly 720 in the flexible tracking photovoltaic system. The supporting part 40 can be fixed as an integral structure with the rotating part 20 through welding or bolt connection. The supporting part 40 can follow the rotating part 20 to perform the rotating action relative to the fixed part 10 under the driving action of the driving part 30. Thus, when the rotating node 730 is used in the flexible tracking photovoltaic system, the photovoltaic panel assembly 720 is driven to rotate to realize the tracking effect on the light.

[0053] The rotating node 730 provided by the embodiment of the present application is fixed on the main cable 710 through the fixing part 10 as the bearing structure of other parts, and the fixing part 10 is fixed on the main cable 710 through the locking part 50, and the fixing part 10 is rotationally connected with the rotating part 20, so that the fixing part 10 keeps position fixed with the main cable 710 in the process of adjusting the rotating node 730, and only the rotating part 20 is adjusted. The structure of the rotating node 730 is arranged without the need of supporting column structure arranged at the bottom, and only the main cable 710 in good tension state can realize stable installation, which can reduce the production cost of the added flexible tracking photovoltaic system. Meanwhile, in the process of rotating and adjusting the photovoltaic panel assembly 720 through the rotating node 730, the main cable 710 only acts as the support part 40 and does not participate in rotation, so that the main cable 710 can keep stable tensioning support effect after being tensioned. The driving part 30 is used to drive the rotating part 20 to perform the rotating action relative to the fixing part 10, and then the support part 40 fixedly connected with the rotating part 20 realizes smooth rotating adjustment of the photovoltaic panel assembly 720. The support base of the above structure is the main cable 710 instead of the column structure, which can be used in the photovoltaic assembly setting scene with large span, so as to improve the power generation efficiency of the flexible tracking photovoltaic system.

[0054] Further, in the rotating node 730 provided by the embodiment of the present application, the rotating cooperation of the fixing part 10 and the rotating part 20 is the basis for realizing the smooth rotation of the support part 40, and the fixing part 10 and the rotating part 20 can realize the rotating cooperation through various structures. In some embodiments of the present application, the fixing part 10 and the rotating part 20 can realize the rotating connection through the slide cooperation, that is, the fixing part 10 and the rotating part 20 are arranged in a laminated manner in the partial region, the fixing part 10 is provided with a guide groove in the laminated region, and the rotating part 20 is provided with a protruding part inserted into the guide groove. The guide groove is a circular arc structure, so that the movement of the protruding part in the guide groove is an arc rotating process. On this basis, the driving part 30 applies a force along the groove direction of the guide groove or at a non-perpendicular angle with the groove direction of the guide groove, so as to realize the sliding of the protruding part in the driving part 30, and then satisfy the rotating action of the rotating part 20 relative to the fixing part 10.

[0055] It should be noted that the rotating connection of the fixing part 10 and the rotating part 20 can also be realized through the slide rail or the slide, and the setting mode is similar to the cooperation mode of the guide groove and the protruding part in the above embodiment, which will not be described here.

[0056] In order to improve the connection effect of the fixed part 10 and the rotating part 20, and avoid the rotating part 20 from falling off the fixed part 10 during rotation, in some embodiments of the application, the fixed part 10 and the rotating part 20 are concentrically arranged in a circular ring structure, and in order to facilitate the connection of the rotating part 20 and the support part 40, the fixed part 10 is preferably arranged in the inner ring of the concentric ring to serve as the basic bearing structure, and the main cable 710 passes through the inner ring of the fixed plate and is connected with the fixed part 10; and the rotating part 20 is arranged in the outer ring of the concentric ring to be directly connected with the support part 40 and other structures at the side wall or outer wall position; on this basis, the sliding bearing 60 is arranged in the sleeving area of the fixed part 10 and the rotating part 20 to realize the rotation of the fixed part 10 and the rotating part 20. At the same time, the sliding bearing 60 is preferably made of high molecular plastic material, which has good resistance to chemical corrosion in outdoor environment, and has good resistance to various strong oxidizing agents such as acid, alkali and salt, and has the characteristics of being lighter than metal, thereby reducing the load burden of the main cable 710 when the rotating node 730 is arranged on the main cable 710.

[0057] It should be noted that the fixed part 10 and the rotating part 20 of the concentric ring structure have a larger overlapping area, and have a more stable connection effect. At the same time, the fixed part 10 and the rotating part 20 are matched by the rotating bearing, which can make the rotating part 20 in contact with the outer wall of the fixed part 10 in the whole area during rotation, and can not cause the problem of rotation deviation or falling off of the rotating part 20. In addition, all the structures of the rotating part 20 can rotate around the fixed part 10, so that the support part 40 has a more free connection posture, that is, the support part 40 only needs to be fixed at any position on the rotating part 20 to meet the rotation effect of the rotating part 20.

[0058] Based on the stable ring-shaped rotating structure realized by the sliding bearing 60, in some embodiments of the application, in order to improve the structural stability of the fixed part 10 and facilitate the stable installation of the main cable 710, the fixed part 10 specifically includes an inner ring frame 110 and a connecting beam 120, wherein the inner ring frame 110 is a regular circular structure, and the two ends of the connecting beam 120 are fixedly arranged at two point positions on the inner wall of the inner ring frame 110 to structurally reinforce the inner ring frame 110 by the supporting action of the connecting beam 120. On this basis, the locking part 50 is matched with the connecting beam 120 to lock the main cable 710, so as to meet the fixed arrangement of the fixed part 10 on the main cable 710. Specifically, at least two main cables 710 pass through and abut one side wall of the connecting beam 120 to provide two connection points for the fixed part 10 to meet the demand of fixed arrangement.

[0059] It should be noted that in the above embodiment, the two main cables 710 are preferably fixed to the same side wall of the connecting beam 120. For example, when the two main cables 710 are on the same horizontal plane relative to the ground, the connecting beam 120 is also arranged horizontally and cushioned at the bottom of the main cables 710. In addition, in order to ensure that the connecting beam 120 can provide a stable reinforcement effect on the inner ring frame 110 and enable the two main cables 710 to provide stable support for the connecting beam 120 and the fixing portion 10, the connecting beam 120 is preferably arranged through the center of the inner ring frame 110, that is, the connecting beam 120 is arranged along a diameter of the inner ring frame 110, and the two locking components 50 are symmetrically arranged on the connecting beam 120 about the midpoint of the connecting beam 120. The connecting beam 120 divides the inner ring frame 110 into two semicircular structures. This allows the locking components 50 on the connecting beam 120, after being fixedly connected to the main cables 710, to provide a more uniform and symmetrical support force for the fixing portion 10 at two symmetrical points on the diameter structure.

[0060] Furthermore, corresponding to the fixed portion 10 including the inner ring frame 110 structure, in some embodiments of the present invention, the rotating portion 20 includes an outer ring frame 210 and a support beam 220, wherein the outer ring frame 210 is sleeved on the outer periphery of the inner ring frame 110 to cooperate with the inner ring frame 110 to form a cavity structure for the arrangement of the sliding bearing 60, so that after the fixed portion 10 is fixed, the rotating portion 20 and the fixed portion 10 can be rotated. The support beam 220 is fixedly arranged on the outer wall surface of the outer ring frame 210, and its position can be set through the plane of the outer ring frame 210 or tangentially arranged with the outer wall surface of the outer ring frame 210. The support beam 220 is used to support the support portion 40 to achieve a stable arrangement of the support portion 40. With the help of the beam structure, the support portion 40 can be fixed to the top surface of the support beam 220 by welding or bolting to meet the load-bearing requirements of the photovoltaic panel assembly 720.

[0061] It should be noted that, since the rotating movement of the outer ring frame 210 is a movement with the center of the inner ring frame 110 as the rotating center, in order to make the movement path of the rotating part 20 more regular, it is preferred that the support beam 220 and the outer ring frame 210 are arranged on the same plane, and the support beam 220 is arranged tangentially to the outer wall surface of the outer ring frame 210; and further, the support beam 220 is arranged parallel to the connecting beam 120 in the fixed part 10 in the assembled state of the support beam 220 in the basic state, i.e., when the rotating part 20 is not rotating, on this basis, when the two main ropes 710 are arranged through the same side surface of the connecting beam 120, the plane formed by the two main ropes 710 is also arranged parallel to the support beam 220, and the support force exerted by the main ropes 710 on the fixed part 10 and the rotating part 20 can be perpendicular to the support beam 220, and the photovoltaic panel assembly 720 carried thereon can be kept in parallel with the main ropes 710; and further, the support beam 220 can be kept in a stable bearing state, and the stable support of the support part 40 and the photovoltaic panel assembly 720 can be satisfied.

[0062] In order to further optimize the above technical solutions, in some embodiments of the present application, the outer ring frame 210 includes an upper shell 2110 and a lower shell 2120 in a semicircular configuration, so as to improve the assembly convenience of the outer ring frame 210 and the inner ring frame 110 through the split structure of the upper shell 2110 and the lower shell 2120. Meanwhile, the splicing area of the upper shell 2110 and the lower shell 2120 is provided with a protrusion, and the protrusion structure is protruded in the direction away from the center of the outer ring frame 210 based on the outer wall of the outer ring frame 210, and the protrusions of the upper shell 2110 and the lower shell 2120 are arranged in abutment after being provided with a through hole, and are fixed and connected into an integral structure by bolts. The split assembly structure of the upper shell 2110 and the lower shell 2120 can arrange the integral structure of the inner ring frame 110 and the sliding bearing 60 in the lower shell 2120 after the sliding bearing 60 is sleeved on the outer periphery of the inner ring frame 110, and the semicircular structure of the lower shell 2120 can directly place the integral structure of the inner ring frame 110 and the sliding bearing 60, and after the integral structure of the inner ring frame 110 and the sliding bearing 60 is placed in position, the upper shell 2110 and the lower shell 2120 are abutted and assembled by bolts, so as to realize the convenient assembly of the rotating part 20, the fixed part 10 and the sliding bearing 60.

[0063] It should be noted that, on the basis of the above structure, the support beam 220 can be first assembled into an integral structure with the upper shell 2110, and is arranged when the upper shell 2110 and the lower shell 2120 are assembled by bolts. In addition, the upper shell 2110 and the lower shell 2120 are fixed at least by two spaced-apart bolts at the single-sided abutment area, so as to improve the stability of the connection structure and avoid the separation risk of the upper shell 2110 and the lower shell 2120 due to the force of the sliding bearing 60 during rotation.

[0064] Since the support cross beam 220 is directly in contact with the support part 40, the structural stability of the support cross beam 220 is the basis for the support part 40 to provide effective support effect for the photovoltaic panel assembly 720, therefore, in some embodiments of the present application, the rotating part 20 further comprises a reinforcing beam 230 to provide structural reinforcement to the support cross beam 220 and can rotate synchronously with the support cross beam 220. Specifically, the two ends of the reinforcing beam 230 are fixedly connected with the outer wall surface of the outer ring frame 210 and the support cross beam 220 respectively, which can be achieved by welding or bolt connection. Since the support cross beam 220 and the outer ring frame 210 are tangent connection structure, after setting the reinforcing beam 230, a single reinforcing beam 230 can form a closed frame structure with the outer ring frame 210 and the support cross beam 220, so that the support cross beam 220 has stronger structural stability. It should be noted that the closed frame structure formed by the reinforcing beam 230, the outer ring frame 210 and the support cross beam 220 can be increased according to the number of reinforcing beams 230, and the reinforcing effect of the support cross beam 220 can be improved accordingly.

[0065] In order to balance the production cost and reinforcing effect of the rotating node 730, in a specific embodiment of the present application, two reinforcing beams 230 are provided, and the two reinforcing beams 230 are symmetrically arranged about the outer ring frame 210. It should be noted that in this embodiment, the support cross beam 220 is also symmetrically arranged about the outer ring frame 210, and the support cross beam 220 is tangentially arranged about the outer wall surface of the outer ring frame 210, and the support cross beam 220 is symmetric about the tangent point on the outer ring frame 210, and the length of the support cross beam 220 on both sides of the tangent point is equal. The two reinforcing beams 230 symmetrically arranged about the outer ring frame 210 need to be connected with the support cross beam 220 respectively, so they also need to be symmetric about the tangent point of the support cross beam 220 on the outer ring frame 210. The support cross beam 220 and the outer ring frame 210 can form two symmetric and equal-area closed frame structures, so that the positions of the two ends of the support cross beam 220 away from the tangent point also have a connection basis, and the support part 40 can be stably supported.

[0066] Further, in the rotating node 730 provided by the embodiment of the present application, the driving part 30 can be a motor, a hydraulic cylinder or other power component for driving the rotating part 20 and the fixed part 10 to generate relative motion, and in some embodiments of the present application, in order to reduce the production cost of the rotating node 730, the driving part 30 adopts an electric push rod 310 with low cost and simple action process, so that the rotating process of the rotating node 730 is stable and effective. Specifically, the electric push rod 310 specifically includes a base 3110 and a telescopic rod 3120, wherein the base 3110 is rotationally arranged on the connecting beam 120, which can be achieved by a pin shaft, a hinge or a bearing structure, and in a specific embodiment of the present application, the end of the base 3110 is in the form of an annular groove, and the connecting beam 120 is provided with a protruding shaft structure on one side, and the annular groove of the base 3110 is sleeved on the outer periphery of the protruding shaft to realize the rotational connection of the two. Here, the protruding shaft is arranged on the side wall of the connecting beam 120 parallel to the inner ring frame 110, so that the driving part 30 can deviate from the fixed part 10 and the rotating part 20, and apply force to the rotating part 20 from one side. The telescopic rod 3120 of the electric push rod 310 includes an action end arranged away from the base 3110, which is rotationally arranged on the support beam 220, which can also be achieved by the cooperation structure of the protruding shaft and the annular groove, and will not be described here. The electric push rod 310 rotationally arranged at both ends can generate a force on the action end of the telescopic rod 3120 and push the support beam 220 to rotate when the length of the telescopic rod 3120 changes, so as to satisfy the length change of the electric push rod 310. On this basis, by adjusting the extension and shortening action of the telescopic rod 3120, the clockwise and counterclockwise rotating action of the support beam 220 based on the fixed part 10 can be realized.

[0067] It needs to be further explained that the electric push rod 310 is arranged to generate force on the support beam 220 and the rotating part 20 in the direction of rotation by changing its length and with the position fixing effect of the fixed part 10, so as to satisfy the rotating drive of the rotating part 20. The electric push rod 310 can be arranged vertically to the connecting beam 120, and the connecting point of the electric push rod 310 and the connecting beam 120 is staggered with the midpoint of the connecting beam 120, so that the connecting point of the electric push rod 310 and the support beam 220 is staggered with the tangent point of the support beam 220 and the outer ring frame 210. At this time, the electric push rod 310 can provide a force to drive the rotating part 20 to perform rotating action when the telescopic rod 3120 is extended and retracted.

[0068] In some embodiments of the present application, the base 3110 is arranged to rotate on the connecting beam 120 at a position offset from the midpoint of the connecting beam 120 in the length direction, and the connecting point of the telescopic rod 3120 on the support beam 220 is also arranged to be offset from the midpoint of the support beam 220, so that the electric push rod 310 can drive the rotating part 20 to rotate without the driving force arm being too short or disappearing.

[0069] Further, in the rotating node 730 provided by the embodiments of the present application, the support part 40 can be a frame structure and is arranged to be fixed on the support part 40 in an integrated structure, or the support part 40 can also be a plurality of separate beam structures and is arranged to be fixed on the support beam 220 respectively. In some embodiments of the present application, the support part 40 includes at least two parallel and spaced support purlins 410. It should be noted that the at least two parallel and spaced support purlins 410 are arranged to simulate the parallel structure of the main cable 710, so as to provide a stable support basis for the photovoltaic panel assembly 720. The two support purlins 410 can be connected into an integrated structure by a plurality of reinforcing bars arranged vertically to the support purlins 410, or can be two separate support purlins 410 and arranged to be fixed on the support beam 220 respectively. The support purlins 410 are arranged in parallel with the main cable 710, so that the photovoltaic panel assembly 720 arranged on the main cable 710 can also be installed on the support purlins 410.

[0070] It should be noted that the support purlin 410 structure can save the material used by the support part 40 and reduce the production cost of the rotating node 730. In order to ensure the support stability of the support part 40 on the basis of saving materials, in some embodiments of the present application, the support purlin 410 is a U-shaped beam to have good rigidity effect. In addition, the opening sides of the two adjacent support purlins 410 are arranged to face each other, so that the two adjacent support purlins 410 can form a stable truss structure when the reinforcing bars are arranged in the middle, and have a tendency to deform towards the opposite inner sides when deformed, thereby avoiding the problem that the two support purlins 410 deform towards the same side when accidentally stressed, and causing the photovoltaic panel assembly 720 to fall off.

[0071] Further, the embodiments of the present application also provide a flexible tracking photovoltaic system, which includes the photovoltaic panel assembly 720 and the photovoltaic support provided by any one of the above embodiments. The photovoltaic panel assembly 720 is arranged on the photovoltaic support to achieve the tracking effect on the light.
