Description

Technical Field

[0001] This application relates to the field of photovoltaic support technology, specifically to an adaptive settlement photovoltaic support structure and method. Background Technology

[0002] With the large-scale development of the photovoltaic energy industry, the contradiction between land resource supply and demand has become increasingly prominent. Coal mining subsidence areas, as a special type of land resource with large areas of idle land, have become an important site selection direction for photovoltaic power station construction due to their concentrated distribution and great development potential. Flexible photovoltaic brackets, with their advantages of large span, low steel consumption, and strong terrain adaptability, have become one of the mainstream choices for photovoltaic projects in coal mining subsidence areas.

[0003] However, coal mining subsidence areas generally exhibit continuous and uneven geological settlement characteristics, posing a critical challenge to the stability and safety of traditional flexible photovoltaic (PV) supports. The support system of a flexible PV support is the core component responsible for bearing PV modules and transmitting loads: when the column settlement exceeds a critical value, the support structure and constraint system will be directly damaged. This manifests as cable breaks due to stress concentration at the ends, and failure of the anchoring system at the column ends (such as anchor slippage or concrete cracking), ultimately leading to the overall collapse of the support and causing huge economic losses such as damage to PV modules and power plant shutdowns. Even if the settlement does not reach the immediate failure threshold, significant stress redistribution will still occur inside the support. Stress concentrations will form at key locations such as cable joints and the connection points between the column and the foundation, making them highly susceptible to fatigue damage under dynamic loads such as wind-induced vibration, significantly shortening the service life of the support and increasing maintenance costs. Publication No. CN223894896U discloses a node of a flexible photovoltaic support and the flexible photovoltaic support itself. The node of the flexible photovoltaic support includes a first connecting component and a second connecting component. The first connecting component is used for fixed connection to a connecting foundation. The second connecting component includes a connector and an adjusting component, with the connector connected to the first connecting component. The adjusting component is used to be detachably clamped between the connector and a tensioning component, and rotatably connected to the connector and / or the tensioning component; alternatively, the adjusting component is used to be detachably clamped between the connector and a U-bolt, and rotatably connected to the connector and / or the U-bolt.

[0004] The rigid connection of flexible photovoltaic brackets cannot adjust the height, or the locking of the adjustment structure is mostly done by bolt fastening, pin insertion and other rigid locking methods. When the elevation needs to be restored, it usually depends on manual operation for jacking. The whole process is labor-intensive, time-consuming and laborious, and cannot be self-adjusted. It is very easy to cause new secondary stress or structural deformation due to improper adjustment. Summary of the Invention

[0005] In view of this, the embodiments of this application aim to provide an adaptive settlement photovoltaic support structure and method, which can automatically or passively compensate for displacement and angle changes when the column settles, so as to improve the adaptability and reliability of the system.

[0006] To achieve the above objectives, the first aspect of this application provides: an adaptive settlement photovoltaic support structure, comprising: Columns; The clamp is configured in a split shape and connected with a connector, wherein the split portion of the clamp extends outward to form a first mounting position; An inclined beam is located on the upper side of the column, and the bottom side of the inclined beam extends outward to form a second mounting position; The support includes a first support rod and a second support rod, with both ends of the first support rod and the second support rod extending to the inner sides of the first mounting position and the second mounting position, respectively. A connecting assembly extends at least partially into the first and second mounting positions and is connected to the clamp or inclined beam. The first and second struts are hinged to the connecting assembly. The connecting assembly includes a deformable portion that extends to support the inclined beam when the column settles and connects the first strut, the second strut, the clamp, and the inclined beam when the column does not settle.

[0007] In some embodiments, the column includes a plug rod, a top rod, and an adjusting member. The plug rod is coaxially disposed below the top rod, and the middle part of the plug rod protrudes and inserts into the top rod. The adjusting member is located inside the top rod, and the adjusting member changes the height of the top rod relative to the plug rod.

[0008] In some embodiments, the top side of the inclined beam has a ring, and the outer side of the inclined beam is fitted with a sleeve plate. The two ends of the ring are at least partially melted and connected to the sleeve plate. The middle part of the inclined beam is concave, and a tension member is provided at the concave part of the inclined beam. A flexible cable is arranged inside the ring. The traction member includes a U-shaped clamping plate, a pressure plate, and a positioning head. The positioning head is connected to the U-shaped clamping plate and extends along a first direction into the inclined beam so that the traction member can swing circumferentially along the positioning head. The pressure plate is fixed to the U-shaped clamping plate by bolts. The flexible cable passes through the ring along a second direction and is supported by the U-shaped clamping plate and the pressure plate.

[0009] In some embodiments, the deformable part includes a sliding member, which includes a first sliding plate, a second sliding plate, and a third sliding plate, the first sliding plate, the second sliding plate, and the third sliding plate being nested in sequence, and the third sliding plate being slidable relative to the second sliding plate, and the second sliding plate being slidable relative to the first sliding plate; A positioning element is provided between the first, second, and third skateboards. The positioning element performs multi-point positioning on the second and third skateboards so that the second or third skateboard can be positioned by the positioning element after sliding.

[0010] In some embodiments, the positioning element includes a ball and a spring, the ball being embedded in the inner side of the second slide plate and the third slide plate respectively, and the first slide plate and the second slide plate having multiple sets of recesses corresponding to the ball positions, the recesses being adapted to the ball; The spring is located inside the ball and supports the ball so that the ball is pushed outward under the action of the spring force.

[0011] In some embodiments, the connecting assembly includes a limiting member, which includes a limiting plate, a knob, a torsion spring, a locking block, and a limiting groove. The limiting plate is located on the bottom side of the inclined beam and is connected to the inclined beam after being at least partially melted. The limiting groove is formed on the side of the limiting plate near the knob. The knob is sleeved on the outside of the first or second support rod, and the first and second support rods can slide along the limiting plate. The torsion spring is disposed between the knob and the first or second support rod so that the knob returns to its original position under the elastic force of the torsion spring after rotation. The locking block is fixed on the outside of the knob and rotates with the knob. The locking block is adapted to the limiting groove. After the locking block is pressed into the limiting groove and engages with the limiting plate, the knob is limited.

[0012] In some embodiments, the knob has a positioning protrusion, the limiting plate has a positioning groove, and the knob is rotated to cause the positioning protrusion to engage with the positioning groove to limit the knob. The locking block is connected to the knob via the pin, so that the locking block can swing relative to the knob.

[0013] In some embodiments, an insert is provided on the inner side of the sliding member, the insert contacts the first sliding plate, and the insert can move up and down relative to the first sliding plate, the up and down movement of the insert changing the squeezing force on the sliding member; Both the first and second sliding plates have grooves on their inner sides. The width of one side of the groove is greater than the width of the other side of the groove, so as to change the gap between the first, second and third sliding plates when the height of the insert changes. Specifically, the gap between the first, second, and third sliding plates increases, and the sliding resistance of the second and third sliding plates decreases; conversely, the gap between the first, second, and third sliding plates decreases, and the sliding resistance of the second and third sliding plates increases.

[0014] In some embodiments, there is a settlement gap between the sleeve plate and the inclined beam, and the sleeve plate extends to one end of the bottom side of the inclined beam and is provided with a connecting plate. The connecting plate is connected to the insert so that when the ring is subjected to the tension of the flexible cable, the insert slides up and down through the sleeve plate and the connecting plate.

[0015] The second aspect of this application provides a method for adaptive settlement of photovoltaic support structures, comprising the following steps: When the column settles and causes changes in stress, the deformable part of the connecting component passively extends to form a new support path. The deformation section extends and triggers the sliding component to slide relative to each other. Under the action of the spring, the ball is inserted into the corresponding recess to complete the repositioning. The change in the tension of the flexible cable alters the position of the sleeve plate, which is transmitted to the insert through the connecting plate. The insert slides up and down, automatically adjusting the sliding resistance to prevent backing. When the column settles excessively, manual intervention is carried out to release the limit, reduce the resistance of the insert, allow sliding, confirm the positioning, and restore the locking.

[0016] The adaptive settlement photovoltaic support system achieves passive or semi-active compensation when uneven settlement of the column or relative displacement caused by temperature and wind load occurs through the hinge and deformation design of the clamp-support rod-connecting components, the resistance control of the nested sliding components and adjustable blocks, and the force transmission path of the traction components and flexible cables. It continuously maintains the design tilt angle and array flatness of the photovoltaic modules, avoids the decrease in power generation efficiency caused by tilt angle deviation, and disperses local tension and displacement through the sleeve, traction components and blocks and converts them into controllable displacement of the sliding components. This significantly reduces stress concentration and fatigue damage of the connecting components and components, and extends the service life of the support system and modules.

[0025] Coal mining subsidence areas generally exhibit continuous and uneven geological settlement characteristics, a core issue that poses a fatal challenge to the stability and safety of traditional flexible photovoltaic (PV) supports. The support system of a flexible PV support is the core component that bears the PV modules and transmits loads: when the column settlement exceeds a critical value, the support structure and constraint system will be directly damaged. Specifically, this manifests as cable breaks due to stress concentration at the ends, and failure of the anchoring system at the column ends (such as anchor slippage or cracking of anchor concrete), ultimately leading to the overall collapse of the support and causing huge economic losses such as damage to PV modules and power plant shutdown. Even if the settlement does not reach the immediate failure threshold, significant stress redistribution will still occur within the support. Stress concentrations will form in key areas such as cable joints and the connection points between the column and the foundation, making them highly susceptible to fatigue damage under dynamic loads such as wind-induced vibration, significantly shortening the service life of the support and increasing maintenance costs.

[0026] Multiple flexible photovoltaic supports can support a row of flexible photovoltaic panels. The support of a row of flexible photovoltaic panels can be divided into local settlement and overall settlement. When overall settlement occurs, the impact on the stability of the flexible photovoltaic supports is relatively minor. However, when local settlement occurs, some of the flexible photovoltaic supports settle, resulting in damage to the support structure and constraint system.

[0027] To address the aforementioned problems, this application provides an adaptive settlement photovoltaic support structure. (See also...) Figure 1-4 As shown, it includes a column 100, a clamp 200, a diagonal beam 300, a support 400, and a connecting assembly 500. The clamp 200 is a split type and is connected with a connector. The split of the clamp 200 extends outward to form a first mounting position 30. The diagonal beam 300 is located on the upper side of the column 100, and the bottom side of the diagonal beam 300 extends outward to form a second mounting position 40.

[0028] The support 400 includes a first support rod 10 and a second support rod 20, with both ends of the first support rod 10 and the second support rod 20 extending to the inner sides of the first mounting position 30 and the second mounting position 40, respectively. The connecting component 500 is at least partially located within the first mounting position 30 and the second mounting position 40 and is connected to the clamp 200 or the inclined beam 300. The first support rod 10 and the second support rod 20 are hinged to the connecting component 500. The connecting component 500 includes a deformable part. When the column 100 settles, the deformable part extends to support the inclined beam 300. When the column 100 does not settle, the deformable part connects the first support rod 10, the second support rod 20, the clamp 200, and the inclined beam 300.

[0029] In this application, the connecting component 500 can be simultaneously disposed within the first mounting position 30 and the second mounting position 40, or it can be disposed separately within the first mounting position 30 or the second mounting position 40.

[0030] The first strut 10 and the second strut 20 change the support path under different working conditions through the deformation part of the connecting component 500, so as to realize adaptive compensation for the settlement of the column 100. When the column 100 settles, it can avoid the rigid constraint from causing the photovoltaic panel to settle synchronously, thus affecting the stability of the constraint system.

[0031] In some embodiments, see Figure 2-3 As shown, the column 100 consists of a plug rod 11, a top rod 12, and an adjusting member 13. The plug rod 11 is coaxially arranged below the top rod 12, and the middle part of the plug rod 11 protrudes and inserts into the top rod 12. The adjusting member 13 is located inside the top rod 12 and is used to change the height of the top rod 12 relative to the plug rod 11, thereby realizing the height fine adjustment and pre-tightening of the column 100 during the installation stage.

[0032] In addition, the clamp 200 is a split component. The two halves of the clamp 200 are connected to the column 100 or to each other at the split by bolts or pins. The split of the clamp 200 extends outward to form the first mounting position 30. The first mounting position 30 is the positioning and bearing position for connecting the end of the first support rod 10.

[0033] The inclined beam 300 is located on the upper side of the column 100, and its bottom side extends outward to form a second mounting position 40. The second mounting position 40 is used to connect the end of the second strut 20 or the other end of the connecting assembly 500. The design of the split clamp 200 and the extended first mounting position 30 facilitates the quick installation of the strut on site and achieves reliable force transmission.

[0034] The combination of insert rod 11, top rod 12, and adjusting member 13 facilitates precise adjustment of the height of column 100 during installation and allows for the provision of settlement compensation space. This application does not limit the structure of adjusting member 13, as long as it can change the height of top rod 12 relative to insert rod 11. For example, in this embodiment, adjusting member 13 is a cylinder, and the extension and retraction of the cylinder can change the height of top rod 12 relative to insert rod 11.

[0035] When the settlement at the support location is large, maintenance personnel can adjust the height of the top rod 12 by controlling the adjusting component 13 to ensure the stability of the photovoltaic panel height. When the settlement at the support location is small, the settlement compensation is achieved by the deformation of the deformation part.

[0036] In some embodiments, see Figure 5-6 As shown, a ring 22 is provided on the top side of the inclined beam 300, and a sleeve plate 21 is fitted on the outer side of the inclined beam 300. The two ends of the ring 22 are at least partially melted and connected to the sleeve plate 21 to form an integrated or semi-integrated connection area. The middle part of the inclined beam 300 is concave, and a tension member 23 is provided in the concave part. A flexible cable 50 is arranged inside the ring 22. The flexible cable 50 is connected to the tension member 23 to stabilize the flexible cable 50 inside the tension member 23.

[0037] The traction member 23 includes a U-shaped clamping plate 31, a pressure plate 32, and a positioning head 33. The positioning head 33 is connected to the U-shaped clamping plate 31 and extends along the first direction into the inclined beam 300, so that the traction member 23 can swing around the positioning head 33 in the circumference. The pressure plate 32 is fixed to the U-shaped clamping plate 31 by bolts. The flexible cable 50 passes through the ring 22 along the second direction and is supported by the U-shaped clamping plate 31 and the pressure plate 32.

[0038] The cooperation between the ring 22 and the sleeve plate 21, as well as the arrangement of the tension member 23 and the flexible cable 50, enable the inclined beam 300 to transmit force through the flexible cable 50 and distribute the force to the sleeve plate 21 and the embedded structure when it is under tension or under changing force, thereby reducing local stress concentration. The circumferential swing capability of the tension member 23 allows the flexible cable 50 to maintain the reliability of the force when the angle changes, so that the component can still be fixed and the force is balanced when the relative position of the inclined beam 300 changes due to the settlement of the column 100.

[0039] Furthermore, the clamping of the traction member 23 on the flexible cable 50 prevents the flexible cable 50 from sliding relative to the support. When some supports settle, this prevents the flexible cable 50 from losing its restraint and causing other photovoltaic panels to shift.

[0040] In some embodiments, see Figure 11-14 As shown, the connecting component 500 includes a sliding member 41, which is composed of a first sliding plate 42, a second sliding plate 43, and a third sliding plate 44 nested in sequence. The second sliding plate 43 can slide relative to the first sliding plate 42, and the third sliding plate 44 can slide relative to the second sliding plate 43. A positioning member 45 is provided between the first sliding plate 42, the second sliding plate 43, and the third sliding plate 44. The positioning member 45 positions the first sliding plate 42 and the second sliding plate 43 at multiple points so that the second sliding plate 43 or the third sliding plate 44 is positioned by the positioning member 45 after sliding.

[0041] It should be noted that the positioning component 45 can be a combination of ball bearings 46 and springs 47. The ball bearings 46 are respectively embedded in the inner side of the second slide plate 43 and the third slide plate 44. The first slide plate 42 and the second slide plate 43 have multiple sets of recesses 48 corresponding to the positions of the ball bearings 46. The recesses 48 are adapted to the ball bearings 46. The springs 47 are set inside the ball bearings 46 and support the ball bearings 46, so that the ball bearings 46 are pushed outward under the elastic force of the springs 47 and locked into the recesses 48 to achieve positioning.

[0042] The nested sliding plate structure provides multi-level sliding capability, allowing relative displacement when the column 100 settles or expands and contracts due to temperature changes; the multi-point positioning of the ball 46 and the recess 48 achieves reliable positioning after sliding, preventing the sliding component 41 from retracting or playing back under wind load or vibration, and ensuring the stability of the angle and position of the inclined beam 300.

[0043] In some embodiments, see Figure 11-12 As shown, an insert 61 is provided on the inner side of the sliding member 41. The insert 61 contacts the first sliding plate 42. The insert 61 can move up and down relative to the first sliding plate 42. The up and down movement of the insert 61 changes the squeezing force on the sliding member 41.

[0044] The first slide plate 42 and the second slide plate 43 each have a groove 62 on their inner sides. The width of one side of the groove 62 is greater than the width of the other side of the groove 62, so as to change the gap between the first slide plate 42, the second slide plate 43 and the third slide plate 44 when the height of the insert 61 changes.

[0045] It should be noted that when the first slide plate 42, the second slide plate 43, and the third slide plate 44 are connected, the second slide plate 43 and the third slide plate 44 are located at the narrow edge of the slide groove 62. At this time, the insert 61 applies force to the first slide plate 42, reducing the gap between the first slide plate 42, the second slide plate 43, and the third slide plate 44, increasing the force required to pull the second slide plate 43 and the third slide plate 44 to slide. At this time, the spring 47 is subjected to greater compressive force. When the insert 61 moves upward, the first slide plate 42 loses its support, and the gap between the first slide plate 42, the second slide plate 43, and the third slide plate 44 increases to facilitate extension.

[0046] When the gap between the first sliding plate 42, the second sliding plate 43, and the third sliding plate 44 increases, the sliding resistance of the second sliding plate 43 and the third sliding plate 44 decreases; when the gap decreases, the sliding resistance increases. There is a settlement gap between the sleeve plate 21 and the inclined beam 300. A connecting plate 63 is provided at one end of the sleeve plate 21 extending to the bottom side of the inclined beam 300. The connecting plate 63 is connected to the insert 61, so that when the ring 22 is subjected to the tension of the flexible cable 50, the insert 61 slides up and down via the sleeve plate 21 and the connecting plate 63.

[0047] The height adjustment of the insert 61 enables variable control of the sliding resistance of the sliding member 41. It can increase the resistance to prevent slippage when needed, or reduce the resistance to facilitate slippage when settlement compensation is required. Through the force transmission path of sleeve 21-connecting plate 63-insert 61, the tension of the flexible cable 50 is converted into the action of the insert 61, realizing the linkage control between the force on the flexible cable 50 and the resistance of the sliding member 41.

[0048] In some embodiments, see Figure 7-10 As shown, the connecting assembly 500 includes a limiting member, which includes a limiting plate 51, a knob 52, a torsion spring 53, a locking block 54, and a limiting groove 55. The limiting plate 51 is located on the bottom side of the inclined beam 300 and is connected to the inclined beam 300 after being at least partially melted. The limiting groove 55 is opened on the side of the limiting plate 51 near the knob 52. The knob 52 is sleeved on the outside of the first support rod 10 or the second support rod 20. The first support rod 10 and the second support rod 20 can slide along the limiting plate 51. The torsion spring 53 is disposed between the knob 52 and the first support rod 10 or the second support rod 20, so that the knob 52 is reset under the elastic force of the torsion spring 53 after rotation. The locking block 54 is fixed on the outside of the knob 52 and rotates with the knob 52. The locking block 54 is adapted to the limiting groove 55. After the locking block 54 is pressed into the limiting groove 55 and engaged with the limiting plate 51, the knob 52 is limited.

[0049] The knob 52 has a positioning protrusion 56 welded to its outer side, and a positioning groove 57 is provided on the limiting plate 51. When the knob 52 is rotated, the positioning protrusion 56 is inserted into the positioning groove 57 to limit the knob 52. The locking block 54 is connected to the knob 52 through a pin so that the locking block 54 can swing relative to the knob 52.

[0050] During adaptive settlement, under the synergistic action of torsion spring 53 and knob 52, the locking block 54 slides along the limiting groove 55 to achieve continuous displacement without interference. When the top rod 12 is supported by the adjusting component 13, rotating the knob 52 causes the locking block 54 to disengage from the limiting groove 55.

[0051] The combination of the limiter and the knob 52 provides a manual or semi-automatic locking function, which makes it easy to fix the position of the strut during installation or maintenance and prevent accidental slippage; the reset function of the torsion spring 53 ensures that the knob 52 returns to the initial position after being unlocked, which facilitates repeated operation and on-site adjustment.

[0052] The ball bearing 46 is embedded inside the first slide plate 42 and the second slide plate 43. The second slide plate 43 and the third slide plate 44 have multiple sets of recesses 48 corresponding to the position of the ball bearing 46. The recesses 48 are adapted to the ball bearing 46. The spring 47 is disposed inside the ball bearing 46 and supports the ball bearing 46, so that the ball bearing 46 is pushed outward and locked into the recess 48 under the elastic force of the spring 47.

[0053] The combination of ball bearing 46, spring 47, and recess 48 enables reliable multi-point positioning and repeatable positioning action. The positioning force is provided by the preload of spring 47, which significantly improves positioning accuracy and vibration resistance, making it suitable for wind load and temperature cycling conditions in outdoor photovoltaic fields.

[0054] In some embodiments, this application also provides an adaptive settlement method for photovoltaic support structures: Position the foundation according to the design location and insert the insertion rod 11 to ensure that the verticality of the column 100 meets the requirements.

[0055] Insert the top rod 12 into the insertion rod 11 and adjust the height of the top rod 12 to the design elevation using the adjusting piece 13, then lock it in place.

[0056] Install the split clamp 200 and fix it with the connector at the split, and confirm the position and angle of the first installation position 30.

[0057] Place the inclined beam 300 on the top rod 12 and fit it into the sleeve plate 21, retaining the designed settlement gap.

[0058] The ends of the first strut 10 and the second strut 20 are inserted into the first mounting position 30 and the second mounting position 40 and hinged to the connecting assembly 500.

[0059] A flexible cable 50 is threaded through and the tensioning member 23 is fixed with a U-shaped clamp 31, a pressure plate 32 and a positioning head 33, and pre-tightened according to the design tension.

[0060] Place the sliding member 41 in the initial locked position, install the limit plate 51 and the knob 52, and check the status of the locking block 54.

[0061] The strut length, the state of the sliding component 41, and the tension of the flexible cable 50 were calibrated point by point, and the baseline data were recorded and archived.

[0062] When the column 100 settles and causes a change in stress, the deformable part of the connecting component 500 passively extends to form a new support path.

[0063] The deformation part extends to trigger the sliding member 41 to slide relative to it, and the ball 46 is engaged in the corresponding recess 48 under the action of the spring 47 to complete the repositioning.

[0064] The change in tension of the flexible cable 50 alters the position of the sleeve plate 21, which is transmitted to the insert 61 via the connecting plate 63. The insert 61 slides up and down, automatically adjusting the sliding resistance to prevent backing out.

[0065] If manual intervention is required, release the limit switch, reduce the resistance of the insert 61 to allow sliding, confirm the positioning, and restore the lock.
