[0002] With the large-scale promotion of new energy photovoltaics in China, the structure of new energy photovoltaic brackets has also changed, from the initial fixed brackets to tracking brackets and then to the flexible brackets that have been promoted more in recent years. The advantage of flexible brackets is that they can adapt to complex terrain, large spans and high space utilization. When the span is large, it will produce a large load on the pile foundation, which will cause some settlement on some bad foundations, resulting in the sinking of the pile foundation, and then causing the bracket to deform and cause the bracket structure to become unstable.

DETAILED DESCRIPTION

[0019] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples or drawings are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0020] A flexible support pile head anti-settling device, such as Figures 1 to 5 As shown, it includes a pile foundation top plate 1, a pile head connecting plate 2, a stabilizing shaft sleeve 3, a stabilizing shaft 4, and an upper top plate 5. The pile foundation top plate 1 is installed on the pile foundation, the pile head connecting plate 2 is installed on the pile foundation top plate 1, the upper top plate 5 is located above the pile head connecting plate 2 and is used to support the cross beam 10, the stabilizing shaft sleeve 3 is located between the pile head connecting plate 2 and the upper top plate 5, and the stabilizing shaft sleeve 3 is fixed on the pile head connecting plate 2, the stabilizing shaft 4 is fixedly installed on the upper top plate 5, and the lower end of the stabilizing shaft 4 extends to the inside of the stabilizing shaft sleeve 3; Two positioning clips 6 are installed at the lower end of the upper top plate 5, and the two positioning clips 6 are symmetrically distributed on both sides of the stabilizing sleeve 3. Two stabilizing clips 7 are placed on the inner side of the positioning clips 6, and a supporting clip 8 is placed on the inner side of the stabilizing clip 7. A spring device 9 is arranged between the supporting clip 8 and the stabilizing sleeve 3. The positioning clips 6, the stabilizing clips 7, and the supporting clips 8 are closely arranged between the pile head connecting plate 2 and the upper top plate 5.

[0021] When the pile foundation first sinks, the stabilizing sleeve 3, the stabilizing clip 7, and the supporting clip 8 sink together with the pile head connecting plate 2 connected to the pile foundation. The stabilizing shaft 4 and the positioning clip 6 remain at the initial height because of the upper top plate 5 connected to the cross beam 10. The spring device 9 increases the friction between the two stabilizing clips 7 and between the stabilizing clip 7 and the supporting clip 8, so that the relative position relationship between the stabilizing clip 7 and the supporting clip 8 remains unchanged, showing a movement state in which the stabilizing clip 7 and the supporting clip 8 move downward relative to the positioning clip 6. With the settlement of the pile foundation, the stabilizing clip 7 and the positioning clip 6 are engaged, the two adjacent stabilizing clips 7 are engaged with each other, and the supporting clip 8 and the stabilizing clip 7 are engaged in sequence, which play a role in supporting the cross beam 10 load at different settlement depths, and can also resist the upward pulling force caused by wind suction, avoiding the top cross beam 10 from generating a large internal force change due to the settlement phenomenon, thereby causing the cross beam 10 to deform, and can allow a certain range of pile foundation settlement to achieve the function of protecting the structural stability of the cross beam 10. like Figure 1 As shown, the inner ends of the positioning card 6 and the stabilizing card 7 are both provided with a card slot 14 , and the outer ends of the stabilizing card 7 and the supporting card 8 are both provided with a card block 15 adapted to the card slot 14 , and the card block 15 is located above the card slot 14 .

[0022] like Figure 4 As shown, a clamping block 16 located inside the stabilizing sleeve 3 is provided at the lower end of the stabilizing shaft 4 .

[0023] When a certain amount of first-stage settlement occurs in the pile foundation, the stabilizing clamp 7 close to the positioning clamp 6 is preset as the outer stabilizing clamp 7, and the clamping block 15 on the outer stabilizing clamp 7 moves down to the same height as the clamping slot 14 on the positioning clamp 6. Under the action of the spring device 9, the clamping block 15 is clamped with the clamping slot 14 to fix the relative position relationship between the outer stabilizing clamp 7 and the positioning clamp 6. At this time, the outer stabilizing clamp 7 cooperates with the positioning clamp 6 to support the load of the top crossbeam 10; Similarly, when the pile foundation undergoes a certain amount of second-stage settlement again, the inner stabilizing clamp 7 moves downward relative to the outer stabilizing clamp 7, and the clamping block 15 on the inner stabilizing clamp 7 is engaged with the clamping groove 14 on the outer stabilizing clamp 7, so that the inner stabilizing clamp 7 can also play a role in supporting the load of the top crossbeam 10; Similarly, when the pile foundation undergoes a certain amount of third-stage settlement for the third time, the support clip 8 moves downward relative to the inner stabilizing clip 7, and the clamping block 15 on the support clip 8 engages with the clamping groove 14 on the inner stabilizing clip 7. The support clip 8 can also play a role in supporting the load of the top beam 10; for settlement at different stages, when under wind suction conditions, the upward pulling force of the beam 10 can be tightened by tightening the nut at the upper end of the stabilizing shaft 4, so that the stabilizing shaft 4 and the clamping block 16 inside the stabilizing sleeve 3 move upward and fit tightly against the upper inner side of the stabilizing sleeve 4 to resist wind suction.

[0024] After the above three times of settlement, the stabilizing shaft 4 reaches the top of the inner wall of the stabilizing sleeve 3, and the relative sliding distance between the stabilizing sleeve 3 and the stabilizing shaft 4 reaches the maximum value. The stabilizing shaft 4 is clamped and fixed to the stabilizing sleeve 3 to prevent the upper structure of the pile head from moving up, thereby ensuring that the pile foundation is stable within a certain range of sinking without affecting the structure of the upper crossbeam 10, thereby ensuring the stability of the upper crossbeam 10.

[0025] The pile head connecting plate 2 is fixed to the pile foundation top plate 1 by fasteners, the pile foundation top plate 1 is fixed to the pile foundation by fasteners, the stabilizing shaft sleeve 3 is fixed to the pile head connecting plate 2 by threaded connection, and the stabilizing shaft 4 is fixedly connected to the upper top plate 5 by threaded fasteners.

[0026] The positioning clamp 6 is fixed on the upper top plate 5 by welding. In the initial state, the lower end of the positioning clamp 6 abuts against the upper end of the pile head connecting plate 2.

[0027] Two angle brackets 12 are arranged at the upper end of the upper top plate 5 , and a beam transition plate 11 is welded to the side of the beam 10 , and the beam transition plate 11 is connected to the angle bracket 12 by bolt fasteners 13 .

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
