[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] like Figure 1 As shown, the present disclosure provides a flexible photovoltaic support foundation, including a support seat 3; an anchor rod 1, the anchor rod 1 can be movably inserted into the support seat 3, and the first end of the anchor rod 1 located on the first side of the support seat 3 can be connected to the steel strand; a spring 2, the spring 2 is sleeved on the anchor rod 1 and is located on the second side of the support seat 3, and the first end of the spring 2 is fixed relative to the support seat 3, and the second end is fixed relative to the anchor rod 1, and the spring 2 can buffer the movement of the anchor rod 1 relative to the support seat 3.

[0030] Specifically, the support seat 3 itself is a rigid foundation, and a hole is provided on the support seat 3 for the anchor rod 1 to pass through. The anchor rod 1 can reciprocate relative to the support seat 3 through the hole. The first end of the anchor rod 1 located on the first side of the support seat 3 is provided with a connecting hole 101 for connecting the steel strand. The steel strand can act on the anchor rod 1 through the connecting hole 101 to cause it to be displaced relative to the support seat 3. The spring 2 connected to the second side of the support seat 3 is compressed or stretched accordingly under the drive of the anchor rod 1. In actual use, one end of the anchor rod 1 is connected to a steel strand. The photovoltaic panel carried by the steel strand generates a constantly changing force at the supporting foundation of the steel strand under the action of active loads such as wind loads. Under the action of the load, the anchor rod 1 reciprocates relative to the support seat 3, and the spring 2 arranged between the anchor rod 1 and the support seat 3 is compressed or stretched under the drive of the anchor rod 1. The force exerted on the anchor rod 1 is buffered by the spring 2 and then acts on the support seat 3 which is a rigid foundation, thereby weakening the impact of the active load on the support seat 3 and avoiding fatigue damage of the flexible photovoltaic support foundation under the reciprocating action of the active load.

[0031] In some embodiments, the diameter of the anchor rod 1 is 0.5 mm-1 mm smaller than the inner diameter of the spring 2 to ensure that the spring 2 does not become unstable during the compression process.

[0032] like Figure 1 As shown, in some embodiments, a pad 4 is provided between the spring 2 and the support seat 3 , and one end of the spring 2 is fixed to the pad 4 .

[0033] Specifically, in order to prevent the stress transmitted from the spring 2 to the support seat 3 from being too concentrated, resulting in local damage to the support seat 3, a pad 4 is provided between the spring 2 and the support seat 3 to disperse the force transmitted from the spring 2 to the support seat 3, expand the load action area on the support seat 3, and effectively extend the service life of the flexible foundation. Moreover, under long-term action, when the pad 4 is partially damaged under the action of the spring 2, it is easy to repair or replace, which does not affect the use of the foundation as a whole, and also reduces the maintenance cost of the flexible foundation during use.

[0034] like Figure 1 As shown, in some embodiments, a stopper 5 is provided on the anchor rod 1, one end of the spring 2 is fixed to the stopper 5, and the position of the stopper 5 on the anchor rod 1 is adjustable.

[0035] Specifically, the stopper 5 is sleeved on the anchor rod 1, and the anchor rod 1 transfers the load to the spring 2 through the stopper 5, and the initial compression of the spring 2 can be adjusted by adjusting the position of the stopper 5 on the anchor rod 1. According to different actual conditions, corresponding adjustments can be made, for example, the position of the stopper 5 on the anchor rod 1 can be adjusted to increase the initial compression of the spring 2, so that the compression that the spring 2 can produce under the same load becomes smaller, and the displacement of the anchor rod 1 relative to the support seat 3 is reduced, so as to weaken the shaking of the photovoltaic panel under the action of the active load and prevent the photovoltaic panel from loosening or falling off; the position of the stopper 5 on the anchor rod 1 can also be adjusted to reduce the initial compression of the spring 2, so that the compression that the spring 2 can produce under the same load becomes larger, and the displacement of the anchor rod 1 relative to the support seat 3 is increased, so as to better buffer the impact effect of the active load on the support seat 3 and prevent the support seat 3 from breaking. Among them, the stopper 5 and the anchor rod 1 can be threadedly connected so that the position of the stopper 5 on the anchor rod 1 can be adjusted by rotating the stopper 5; a slide rail and a limit block corresponding to the stopper 5 can also be set on the anchor rod 1, and the stopper 5 can be slid to the corresponding position on the anchor rod 1 and then locked to meet the use requirements.

[0036] like Figure 1 As shown, in some embodiments, it further includes a sleeve 6 sleeved outside the spring 2 and the stopper 5, and one end of the sleeve 6 is fixed to the backing plate 4.

[0037] Specifically, the sleeve 6 is used to protect and limit the spring 2 and the stopper 5. Lubricating oil can be applied to the inside of the sleeve 6 to ensure that the spring 2 and the stopper 5 can be smoothly extended or compressed in the sleeve 6. When the steel strand applies a force perpendicular to the extension direction of the spring 2 to the anchor rod 1, the inner wall of the sleeve 6 cooperates with the hole of the support seat 3 to limit the displacement of the anchor rod 1 perpendicular to the extension direction of the spring 2, thereby improving the stability of the flexible foundation.

[0038] In some embodiments, the inner diameter of the sleeve 6 is 1 mm-2 mm larger than the diameter of the stopper 5 , which not only facilitates the movement of the stopper 5 inside the sleeve 6 , but also effectively limits the displacement of the anchor rod 1 in a direction perpendicular to the expansion and contraction direction of the spring 2 .

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the flexible photovoltaic support foundation further includes a haunch plate 7 , one side of the haunch plate 7 is fixed to the pad 4 , and the other side of the haunch plate 7 is fixed to the outer wall of the sleeve 6 .

[0040] Specifically, the axil plate 7 is used to transfer the force applied to the sleeve 6 perpendicular to the expansion and contraction direction of the spring 2 to the pad 4, so as to improve the bending resistance of the sleeve 6. When the steel strand applies a force perpendicular to the expansion and contraction direction of the spring 2 to the anchor rod 1, the sleeve 6 is displaced under the action of the stopper 5. To prevent the sleeve 6 from bending and damage, the axil plate 7 is provided at the connection between the sleeve 6 and the pad 4, so as to enhance the sleeve 6's ability to withstand loads in this direction.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, the flexible photovoltaic support base includes a plurality of haunch plates 7 , and the plurality of haunch plates 7 are evenly distributed around the central axis of the sleeve 6 .

[0042] Specifically, under the influence of active loads, the size and direction of the load applied by the steel strand to the anchor rod 1 are constantly changing. Multiple axle plates 7 are evenly arranged around the central axis of the sleeve 6, which significantly enhances the bending resistance of the sleeve 6 in all directions and improves the stability of the flexible foundation.

[0043] like Figure 1 and Figure 2 As shown, in some embodiments, the inner periphery of the sleeve 6 is provided with a first limiting portion 601 located between the backing plate 4 and the stopper 5 .

[0044] Specifically, the first limiting portion 601 is used to limit the displacement of the stopper 5 when the spring 2 is compressed. When the load is too large, in order to limit the compression stroke of the spring 2 and prevent the spring 2 from being over-compressed and causing plastic deformation, which causes permanent loss of the buffering capacity of the flexible foundation, the first limiting portion 601 is provided on the inner circumference of the sleeve 6. When the spring 2 is compressed to the first limiting portion 601, the stopper 5 at one end of the spring 2 contacts the first limiting portion 601 to prevent the spring 2 from being further compressed, thereby protecting the spring 2 from normal compression within a certain limit and improving the reliability of the flexible foundation.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, a second limiting portion 602 is provided at one end of the sleeve 6 away from the backing plate 4 .

[0046] Specifically, the second limiting portion 602 is used to limit the displacement of the stopper 5 when the spring 2 is extended. Since the size and direction of the load are constantly changing, the spring 2 is affected by the impact force and will have a certain amount of extension. When the spring 2 has an excessive amount of extension, the stopper 5 at one end of the spring 2 contacts the second limiting portion 602 to prevent the stopper 5 from rushing out of the sleeve 6, causing the device to malfunction.

[0047] like Figure 2 As shown, in some embodiments, a ventilation hole 603 is provided on the second limiting portion 602. To ensure that the stopper 5 and the spring 2 can be normally extended and retracted inside the sleeve 6, a ventilation hole 603 is provided on the second limiting portion 602 to ensure that the air inside the sleeve 6 can flow normally during the extension and retraction stroke of the stopper 5 and the spring 2.

[0048] The present disclosure also provides a photovoltaic power generation device, which includes a photovoltaic panel, a steel strand for supporting the photovoltaic panel and the above-mentioned flexible photovoltaic support base, wherein both ends of the steel strand are connected to the flexible photovoltaic support base.

[0049] Specifically, the photovoltaic panels carried by the steel strands are subjected to loads of constantly changing magnitude and direction under the action of active loads such as wind loads. The steel strands in turn apply the loads to the flexible photovoltaic support foundation, which receives the load from the steel strands through the connecting hole 101 at one end of the anchor rod 1 and is transferred to the support seat 3 by the spring 2. The support seat 3 is a rigid foundation, and the load is first buffered by the spring 2 before acting on the support seat 3, avoiding direct action on the support seat 3. The buffering effect of the spring 2 is utilized to weaken the impact force of the active load on the support seat 3, thereby effectively avoiding fatigue damage to the foundation of the photovoltaic bracket under the action of active loads.
