[0070] See Figure 1-Figure 3 An embodiment of the present application provides a support structure, which includes a base assembly 100, at least one support rod assembly 200, and a support frame 300. The base assembly 100 is used to be fixed on the ground or any fixed part; the support rod assembly 200 includes a mother support rod 210, a sub-support rod 220, a locking mechanism 230 and a clamping mechanism 240. One end of the mother support rod 210 is connected to the base assembly 100; one end of the sub-support rod 220 is inserted into the mother support rod 210, and the insertion depth can be adjusted. The locking mechanism 230 is arranged between the sub-support rod 220 and the mother support rod 210 and is located in the radial direction of the two, and is used to lock the two; the clamping mechanism 240 is arranged on one side of the locking mechanism 230 along the insertion direction of the sub-support rod 220, and the clamping mechanism 240 is arranged between the inner wall of the mother support rod 210 and the outer wall of the sub-support rod 220, and the outer wall of the clamping mechanism 240 abuts against the inner wall of the mother support rod 210, and the inner wall of the clamping mechanism 240 abuts against the outer wall of the sub-support rod 220. The support frame 300 is used to install the photovoltaic assembly 500 . The support frame 300 is disposed at one end of the sub-support pole 220 outside the main support pole 210 .

[0071] In this embodiment, the base assembly 100 is fixed on the ground or other fixed parts, and the mother support rod 210 is connected to the base assembly 100, so that the support rod assembly 200 is fixed on the ground or other fixed parts through the base assembly 100; at the same time, part of the sub-support rod 220 is inserted into the mother support rod 210, and the insertion depth can be adjusted, and the clamping mechanism 240 is used to clamp the mother support rod 210 and the sub-support rod 220 at the same time, and the locking mechanism 230 can lock the relative position of the sub-support rod 220 and the mother support rod 210, that is, the height of the support rod assembly 200 is adjustable, so that the photovoltaic assembly 500 can be installed at any height as needed. The clamping mechanism 240 and the locking mechanism 230 are used simultaneously. On the one hand, they are used to increase the locking effect between the sub-strut 220 and the mother strut 210. On the other hand, they provide two contact points between the sub-strut 220 and the mother strut 210 to ensure that the axial directions of the sub-strut 220 and the mother strut 210 always coincide with each other, preventing the sub-strut 220 from swinging radially relative to the mother strut 210 under the action of external force.

[0072] For large-scale photovoltaic power stations, the support frame 300 requires the support of multiple support rod assemblies 200 at the same time. Due to the undulating terrain, the installation heights of different base assemblies 100 are different, which requires adjusting the height of the corresponding support assembly according to the installation height of the base assembly 100, so that the tops of all sub-support rods 220 in the same area are on the same plane, thereby ensuring that the support frames 300 in the area are on the same plane or inclined surface. That is, the support structure of the present application can enable the entire photovoltaic power station to maintain stable installation and operation in a complex mountain environment. In addition, for the single-body photovoltaic assembly 500 supported by a single support rod assembly 200, the support rod assembly 200 is retractable to meet the personalized needs of different installation heights of the photovoltaic assembly 500.

[0073] In some embodiments, combined Figure 9 The base assembly 100 is used to be fixed on any plane or inclined surface, and one end of the mother support rod 210 away from the sub-support rod 220 is rotatably connected to the base assembly 100, and the inclination angle of the mother support rod 210 relative to the base assembly 100 is adjustable.

[0074] In this embodiment, the base assembly 100 is fixed on any plane or inclined plane, so that the base can be installed at any position on the mountain; the mother support rod 210 is rotatably connected to the base assembly 100 and the angle is adjustable, that is, no matter at what angle the base is installed, the angle of the mother support rod 210 can be adjusted so that the mother support rod 210 is set in the vertical direction, which is convenient for supporting the support frame 300 installed with the photovoltaic component 500 in the direction of gravity.

[0075] In some embodiments, the base assembly 100 includes a base 110 and a first shell 120, and a first arc-shaped groove 111 is respectively provided on the base 110 and the first shell 120. The first shell 120 is also provided with a through hole connected to the first arc-shaped groove. When the first shell 120 is covered on the base 110, the two first arc-shaped grooves are buckled into a first spherical cavity. A first ball head 140 is provided at the bottom of the support rod assembly 200, and the first ball head 140 is located in the first spherical cavity. The support rod assembly 200 extends out of the through hole.

[0076] In actual use, the base 110 is first fixed on any flat or inclined surface, and then the female support rod 210 is passed through the through hole of the first shell 120. The first ball head 140 is then positioned within the first arcuate groove 111 of the base 110. The first shell 120 is then placed over the base 110. The first shell 120 and the base 110 are then pre-fixed with bolts. The female support rod 210 is then adjusted in angle so that it is vertically aligned, and finally the first shell 120 and the base 110 are fastened with bolts. The base 110 is mounted on the mountain using expansion screws.

[0077] In some other embodiments, in application scenarios where the ground or the surface of the fixed part is flat, there is no need to adjust the inclination angle of the support rod assembly 200. That is, only a screw hole needs to be opened on the base assembly 100, and the end of the mother support rod 210 away from the child support rod 220 can be directly threadedly connected to the screw hole, which is convenient for installation.

[0078] In some embodiments, combined Figure 3-Figure 5 The locking mechanism 230 includes a locking sleeve 231 and a locking clamp 232. The locking sleeve 231 is fixed on the inner side of the mother support rod 210, and the locking clamp 232 is sleeved on the outside of the sub-support rod 220 and can slide axially along the sub-support rod 220; the locking sleeve 231 is used to be sleeved on the outside of the locking clamp 232, and the inner diameter of the locking sleeve 231 and / or the outer diameter of the locking clamp 232 gradually changes along the insertion direction of the sub-support rod 220, so that the locking sleeve 231 and the locking clamp 232 move relative to each other in the radial direction and press the sub-support rod 220.

[0079] During installation, the locking sleeve 231 is first fixed to the mother strut 210, and then the locking clamp 232 is placed on the sub-strut 220. The sub-strut 220 is then inserted into the mother strut 210 so that the locking clamp 232 gradually penetrates into the locking sleeve 231. At this time, due to the gradual reduction in the size of the locking sleeve 231 and / or the gradual increase in the size of the locking clamp 232, the locking clamp 232 can clamp the sub-strut 220 inside, thereby achieving the locking of the wooden strut and the sub-strut 220. Before being locked, the locking clamp 232 can slide on the support rod, that is, it can lock the sub-strut 220 with the locking sleeve 231 on the mother strut 210 at any position.

[0080] Specifically, the inner diameter of the locking sleeve 231 and / or the outer diameter of the locking clamp 232 gradually change along the insertion direction of the sub-strut 220, so that the locking sleeve 231 and the locking clamp 232 move relative to each other in the radial direction and compress the sub-strut 220. It can be considered that along the insertion direction of the sub-strut 220, the inner diameter of the locking sleeve 231 remains unchanged while the outer diameter of the locking clamp 232 gradually increases; or the inner diameter of the locking clamp 232 remains unchanged while the inner diameter of the locking sleeve 231 gradually decreases; or the outer diameter of the locking clamp 232 gradually increases while the inner diameter of the locking sleeve 231 gradually decreases; or the outer diameter of the locking clamp 232 and the inner diameter of the locking sleeve 231 both gradually decrease, but the reduction in the outer diameter of the locking clamp 232 is less than the reduction in the inner diameter of the locking sleeve 231.

[0081] Of course, the outer diameter of the locking clamp 232 and the inner diameter of the locking sleeve 231 can also gradually decrease, and the reduction amplitude of the two is equal, but the outer diameter of the locking clamp 232 is greater than or equal to the inner diameter of the locking sleeve 231, that is, the locking clamp 232 and the locking sleeve 231 have an interference fit, and the locking clamp 232 can shrink radially inward.

[0082] In this embodiment, since the locking clamp 232 and the locking sleeve 231 are interference fit, and the locking clamp 232 can shrink radially inward, when the locking clamp 232 is inserted into the locking sleeve 231, the locking sleeve 231 can pressurize the locking clamp 232 to shrink inward, and then the locking clamp 232 clamps the sub-support rod 220.

[0083] Furthermore, the locking clamp 232 includes two clamping members 2321 that are radially opposite and spaced apart along the sub-support rod 220, each clamping member 2321 includes an arc-shaped inner wall 2322 and a plurality of wedge blocks 2323 arranged outside the arc-shaped inner wall 2322, and the plurality of wedge blocks 2323 are arranged in sequence along the circumference of the arc-shaped inner wall 2322; and along the insertion direction, the outer wall of each wedge block 2323 is radially inclined inward.

[0084] In actual use, since the inner diameter of the locking sleeve 231 gradually decreases, when the locking clamp 232 is inserted into the locking sleeve 231, the locking clamp 232 squeezes multiple wedge blocks 2323 so that the two wedge blocks 2323 are close to each other, and the distance between the two adjacent wedge blocks 2323 gradually decreases, so that the two arc-shaped inner walls 2322 clamp the outer wall of the sub-support rod 220.

[0085] In order to enhance the friction between the arc-shaped inner wall 2322 and the sub-support rod 220 , a friction structure may be added to the arc-shaped inner wall 2322 , for example, diamond-shaped knurling may be performed on the arc-shaped inner wall 2322 by sandblasting.

[0086] In some embodiments, the female support rod 210 is provided with a threaded connection section 211 on one side along the first direction; the locking sleeve 231 is threadedly connected with the threaded connection section 211, so as to realize the fixed connection between the locking sleeve 231 and the female support rod 210. During installation, only the position of the locking clamp block 232 on the male support rod 220 needs to be adjusted, so as to realize the telescopic extension of the support rod assembly 200.

[0087] Further, the locking mechanism 230 comprises a compression nut 235, which is sleeved outside the male support rod 220. The compression nut 235 is located on the side of the locking clamp block 232 away from the insertion direction, and is threadedly connected with the threaded connection section 211.

[0088] Still further, the locking mechanism 230 further comprises a flat washer 233 and a lock washer 234. The flat washer 233, the lock washer 234 and the compression nut 235 are sequentially stacked, and the lock washer 234 is provided with anti-skid lines on the side close to the compression nut 235. The flat washer 233 is arranged on the locking clamp block 232, and the compression nut 235 has external threads which are connected with the internal threads of the female support rod 210. During installation, when the compression nut 235 is rotated, the compression nut 235 can sequentially press the locking clamp block 232 through the lock washer 234 and the flat washer 233, so as to move the locking clamp block 232 downward, to press the locking clamp block 232 through the locking sleeve 231, and to clamp the support rod through the locking clamp block 232.

[0089] In some embodiments, the locking mechanism 230 further comprises a top cover 236, which is provided with a through hole for the male support rod 220 to pass through. The top cover 236 is arranged outside the end of the female support rod 210 having the threaded connection section 211, and is sealingly connected with the male support rod 220.

[0090] The top cover 236 is arranged on the top of the female support rod 210, and is sealingly connected with the male support rod 220, so as to prevent rainwater from entering between the male support rod 220 and the female support rod 210, and causing rust inside the male support rod 220 and the female support rod 210 under long-term action.

[0091] In some embodiments, in combination with Figure 6-Figure 8 The holding mechanism 240 comprises a holding outer sleeve 241 and a holding inner sleeve 242. The holding outer sleeve 241 is fixed in the female support rod 210, and the holding inner sleeve 242 is sleeved outside the male support rod 220. When the male support rod 220 is inserted into the female support rod 210, the holding outer sleeve 241 can be sleeved outside the holding inner sleeve 242, and the inner diameter of the holding outer sleeve 241 and / or the outer diameter of the holding inner sleeve 242 gradually changes along the insertion direction of the male support rod 220, so that the holding outer sleeve 241 and the holding inner sleeve 242 move relatively in the radial direction and hold the male support rod 220.

[0092] The radial variation of the clamping outer sleeve 241 and the clamping inner sleeve 242 may refer to the radial variation between the above-mentioned locking outer sleeve 231 and the locking clamping block 232 .

[0093] In some embodiments, the clamping outer sleeve 241 includes an internal thread segment 2411 and a clamping cavity 2412 arranged in sequence along the insertion direction; the clamping inner sleeve 242 includes an external thread segment 2421 and a clamping block 2422 arranged in sequence along the insertion direction; wherein, the internal thread segment 2411 is threadedly connected to the external thread segment 2421, and the clamping block 2422 is used to be inserted into the clamping cavity 2412, and the inner wall of the clamping cavity 2412 abuts against the outer wall of the clamping block 2422.

[0094] Specifically, one of the sub-strut 220 and the gripping inner sleeve 242 is provided with a mating groove 221, and the other is provided with a limiting protrusion 2423. The mating groove 221 engages with the limiting protrusion 2423. For example, the sub-strut 220 is provided with an axially extending mating groove 221, and the gripping inner sleeve 242 is provided with a limiting protrusion 2423. When the sub-strut 220 is rotated, the gripping inner sleeve 242 and the sub-strut 220 can be ensured to rotate simultaneously.

[0095] During installation, first fix the clamping sleeve 241 in the mother support rod 210. Specifically, the clamping sleeve 241 can be directly installed in the mother support rod 210 in the factory; then the clamping inner sleeve 242 is mounted on the outside of the sub-support rod 220, and the position of the clamping inner sleeve 242 on the sub-support rod 220 is adjusted according to the required length of the support rod assembly 200; then rotate the sub-support rod 220 forward to drive the clamping inner sleeve 242 to rotate relative to the clamping sleeve 241, and then make the clamping inner sleeve 242 move downward relative to the clamping sleeve 241, so that the clamping block 2422 is gradually inserted into the clamping cavity 2412, and then make the inner wall of the clamping cavity 2412 abut against the outer wall of the clamping block 2422, that is, the installation of the clamping mechanism 240 is completed.

[0096] When adjusting the length of the support rod assembly 200, the sub-strut 220 is rotated in the reverse direction. At this time, the sub-strut 220 drives the clamping inner sleeve 242 to rotate relative to the clamping outer sleeve 241, so that the clamping inner sleeve 242 moves upward relative to the clamping outer sleeve 241, that is, the clamping block 2422 is partially withdrawn from the clamping cavity 2412. The sub-strut 220 is then pulled axially until the height of the sub-strut 220 is adjusted to the desired height. The sub-strut 220 is then rotated forward again to re-clamp the sub-strut 220 through the clamping mechanism 240. In addition, when adjusting the height of the sub-strut 220, it should be ensured that the bottom of the sub-strut 220 is always connected to the mother strut 210 through the clamping mechanism 240.

[0097] After the clamping mechanism 240 is installed, the locking sleeve 231 is passed through the sub-support rod 220 and threadedly connected to the threaded connection section 211 on the mother support rod 210, and then the locking clamp block 232, flat washer 233, anti-loosening washer 234 and tightening nut 235 are sequentially mounted on the sub-support rod 220, and the tightening nut 235 is rotated so that the tightening nut 235 squeezes the locking clamp block 232 through the anti-loosening washer 234 and the flat washer 233 in turn, so that the locking clamp block 232 moves downward, and then the locking sleeve 231 squeezes the locking clamp block 232 to clamp the support rod through the locking clamp block 232; finally, the top cover 236 is passed through the sub-support rod 220 to cover the top of the mother support rod 210, and the top cover 236 and the sub-support rod 220 are glued together.

[0098] In some embodiments, there are multiple clamping blocks 2422, and the multiple clamping blocks 2422 are arranged in a ring-shaped manner and spaced apart in sequence. Along the insertion direction, the outer wall of each clamping block 2422 is radially inclined inward.

[0099] In this embodiment, the outer wall of each clamping block 2422 is radially inwardly inclined along the insertion direction, so that the clamping block 2422 can be quickly inserted into the clamping cavity 2412. Moreover, because the multiple clamping blocks 2422 are arranged in a ring-shaped manner and spaced apart in sequence, when the clamping blocks 2422 continue to be inserted downward into the clamping cavity 2412, the clamping cavity 2412 can simultaneously squeeze the multiple clamping blocks 2422, causing the multiple clamping blocks 2422 to move radially inward, thereby clamping the sub-bracing rod 220.

[0100] In some embodiments, the inner diameter of the clamping cavity 2412 gradually decreases along the insertion direction, which can increase the contact area between the inner wall of the clamping cavity 2412 and the clamping block 2422, thereby improving the stability of the sub-strut 220.

[0101] Specifically, an avoidance cavity 2413 is further provided between the clamping cavity 2412 and the internal thread section 2411. The inner diameter of the avoidance cavity 2413 close to one end of the internal thread section 2411 is larger than the maximum outer diameter of the external thread section 2421 of the clamping inner sleeve 242, so that the external thread section 2421 can extend into the avoidance cavity 2413, ensuring that the clamping outer sleeve 241 can clamp the clamping inner sleeve 242.

[0102] In some embodiments, combined Figure 10-13The diagonal bracing member 400 comprises a diagonal bracing rod set 410, a tensioning assembly 420, and a locking assembly 430. One end of the diagonal bracing rod set 410 is rotationally connected to the support frame 300. The tensioning assembly 420 has a first rotation part 423 and a second rotation part 424 arranged at intervals. The first rotation part 423 is rotationally connected to the other end of the diagonal bracing rod set 410. The second rotation part 424 is rotationally connected to the support rod assembly 200. When the tensioning assembly 420 rotates around the second rotation part 424, the first rotation part 423 can be swung. The locking assembly 430 is arranged on the support rod assembly 200. The locking assembly 430 is used to fix the tensioning assembly 420.

[0103] In the embodiment, the diagonal bracing member 400 is used to connect the support rod assembly 200 and the support frame 300 connected to each other, so as to enhance the connection rigidity of the support rod assembly 200 and the support frame 300 by the principle of triangular stability, and prevent deformation under force.

[0104] In the embodiment, after the support rod assembly 200 and the support frame 300 are connected to each other, first, one end of the diagonal bracing rod set 410 is connected to the support frame 300. One end of the tensioning assembly 420 is connected to the diagonal bracing rod set 410 through the first rotation part 423, and the other end is connected to the support rod assembly 200 through the second rotation part 424. Then, the tensioning assembly 420 is rotated, so that the first rotation part 423 rotates around the second rotation part 424. When the first rotation part 423 rotates, the diagonal bracing rod set 410 can be rotated, so that the two ends of the diagonal bracing rod set 410 are in a tensioned state. Then, the tensioning assembly 420 is locked by the locking assembly 430. Thus, the stable connection of the diagonal bracing member with the support frame 300 and the support rod assembly 200 is achieved, the stability of the entire photovoltaic is enhanced, and the service life of the photovoltaic support is prolonged. After the two ends of the diagonal bracing rod set 410 are tensioned by the tensioning assembly 420, the virtual position shaking caused by the installation error of the photovoltaic assembly can be effectively eliminated, and the dual loads of gravity settlement and typhoon uplift can be resisted, so that the structural durability of the photovoltaic support under extreme weather conditions is significantly improved.

[0105] In some embodiments, the tensioning assembly 420 comprises a first connecting section 421 and a second connecting section 422 connected in sequence. The first rotation part 423 is arranged at one end of the first connecting section 421 away from the second connecting section 422. The locking assembly 430 is used to lock the second connecting section 422. The second rotation part 424 is located between the first rotation part 423 and the locking assembly 430.

[0106] In this embodiment, the second rotating portion 424 is located between the first rotating portion 423 and the locking assembly 430. That is, the tensioning assembly 420 is equivalent to a lever arm, and the second rotating portion 424 is a fulcrum. When the second connecting section 422 rotates, the first rotating portion 423 can drive the diagonal brace assembly 410 to swing around the second rotating portion 424. When the locking assembly 430 locks the second connecting section 422, the first connecting section 421 can be fixed, thereby placing the diagonal brace assembly 410 in a tensioned state.

[0107] The support rod assembly 200 extends vertically, and the support frame 300 is disposed on top of the support rod assembly 200. The rotation axis of the first rotating portion 423 and the rotation axis of the second rotating portion 424 both extend horizontally, thereby enabling the first rotating portion 423 to drive the diagonal support rod assembly 410 to swing up and down around the second rotating portion 424.

[0108] Furthermore, the locking assembly 430 includes a first bolt 431 and a second bolt 432 , and the first bolt 431 and the second bolt 432 are respectively in contact with two opposite sides of the second connecting section 422 along the swinging direction.

[0109] In this embodiment, the first rotating portion 423 drives the diagonal support rod group 410 to swing up and down around the second rotating portion 424, so that the first bolt 431 is located above the second connecting section 422, and the first bolt 431 abuts against the upper part of the second connecting section 422, and the second bolt 432 is located below the second connecting section 422, and the second bolt 432 abuts against the bottom of the second connecting section 422, that is, the first bolt 431 and the second bolt 432 clamp the second connecting section 422 in the upper and lower directions respectively, thereby locking the entire tensioning assembly 420.

[0110] In some embodiments, the diagonal support member includes a clamp 440 , which is used to clamp onto the support rod assembly 200 ; the second rotating portion 424 is rotatably connected to the clamp 440 , and the locking assembly 430 is disposed on the clamp 440 .

[0111] In this embodiment, the entire diagonal bracing member 400 is fastened to the support rod assembly 200 via a clamp 440. This allows the clamp 440 to move the diagonal bracing member 400 along the support rod assembly 200, thereby supporting photovoltaic modules 500 at different tilt angles. For example, when the photovoltaic module 500 is tilted, the higher and lower sides are each connected to a diagonal bracing member 400. By adjusting the lengths of the two diagonal bracing members 400, one diagonal bracing member 400 can support the higher side of the support frame 300, while the other diagonal bracing member 400 supports the lower side of the support frame 300.

[0112] In some embodiments, the clamp 440 comprises two ears 443 extending radially, the second rotating part 424 is rotatably connected with the two ears 443, and the second connecting segment 422 extends into the space between the two ears 443; the locking assembly 430 comprises a locking hoop 433 sleeved on the two ears 443, the locking hoop 433 is provided with threaded holes 4331 on both sides of the clamp 440 in the axial direction, and the first bolt 431 and the second bolt 432 pass through the threaded holes 4331 to abut against the second connecting segment 422.

[0113] The locking hoop 433 is a rectangular sleeve, the locking hoop 433 is sleeved on the two ears 443, the second connecting segment 422 is located between the two ears 443, the first bolt 431 passes through the threaded hole 4331 on the upper part of the locking hoop 433 to abut against the upper part of the second connecting segment 422 between the two ears 443, and the second bolt 432 passes through the threaded hole 4331 on the lower part of the locking hoop 433 to abut against the lower part of the second connecting segment 422 between the two ears 443.

[0114] In some embodiments, in the direction away from the first connecting segment 421, the second connecting segment 422 gradually decreases in size in the axial direction of the clamp 440, and the locking assembly 430 is arranged at the end of the second connecting segment 422 with smaller size.

[0115] In the embodiment, the second connecting segment 422 gradually decreases in size in the axial direction of the clamp 440, and the first bolt 431 and the second bolt 432 are arranged at the end of the second connecting segment 422 with smaller size, so as to reduce the distance between the first bolt 431 and the second bolt 432 and reduce the size of the entire locking hoop 433 in the vertical direction.

[0116] In some embodiments, the first connecting segment 421 and the second connecting segment 422 are arranged at an obtuse angle.

[0117] In some embodiments, the angle between the first connecting segment 421 and the second connecting segment 422 is greater than 90° and less than 180°, and the obtuse angle design makes the tensioning assembly 420 form a longer force arm when rotating, so that a larger tensioning force can be generated by a smaller operating force, thereby significantly improving the tensioning efficiency.

[0118] In some embodiments, the diagonal support member further comprises a triangular support rod, one of the vertices of the triangular support rod is rotatably connected with the support rod assembly 200, and the other two vertices of the triangular support rod are fixedly connected with the support frame 300.

[0119] In some embodiments, in combination with Figures 14-18The diagonal support rod set 410 comprises a first diagonal support rod 450, a hoop assembly 460 and a second diagonal support rod 470 connected in sequence, one end of the first diagonal support rod 450 away from the hoop assembly 460 is rotationally connected with the support frame 300, one end of the second diagonal support rod 470 away from the hoop assembly 460 is rotationally connected with the tensioning assembly 420, the hoop assembly 460 is fixedly connected with the outer wall of the first diagonal support rod 450, the second diagonal support rod 470 can slide along the axial direction relative to the first diagonal support rod 450, and the hoop assembly 460 is used for locking the second diagonal support rod 470.

[0120] In the embodiment, the base assembly 100 can be stably fixed on the ground or any fixing member, and provides a stable installation basis for the whole support rod assembly 200; one end of the support rod assembly 200 is connected with the base assembly 100, and the other end is rotationally connected with the support frame 300, so that the inclination angle of the photovoltaic assembly 500 on the support frame 300 can be adjusted. The second diagonal support rod 470 of the diagonal support member 400 can slide along the axial direction relative to the first diagonal support rod 450, and meanwhile the hoop assembly 460 can lock the second diagonal support rod 470 at any position, so that the length of the diagonal support member 400 can be adjusted, thereby facilitating the support of the photovoltaic assembly 500 with different inclination angles, and meeting the support requirement of the photovoltaic assembly 500 with a large inclination angle.

[0121] Further, the hoop assembly 460 comprises a first hoop 461 and a second hoop 462 coaxially connected, the first hoop 461 is fixed outside the first diagonal support rod 450, the second hoop 462 is fixed outside the second diagonal support rod 470, and the second hoop 462 can be limitedly matched with any position of the second diagonal support rod 470 along the axial direction.

[0122] In the embodiment, the hoop assembly 460 comprises a first hoop 461 and a second hoop 462 coaxially connected, the first hoop 461 is fixed outside the first diagonal support rod 450, the second hoop 462 is fixed outside the second diagonal support rod 470, and the second hoop 462 can be limitedly matched with any position of the second diagonal support rod 470 along the axial direction. When the inclination angle of the photovoltaic assembly 500 needs to be adjusted, the second diagonal support rod 470 can be flexibly slid to change the total length of the diagonal support member 400, and then the second diagonal support rod 470 is locked by the second hoop 462, so that the length adjustment of the diagonal support member 400 is completed.

[0123] Specifically, one of the first diagonal support rod 450 and the hoop assembly 460 is provided with a limiting groove 451, and the other is provided with a protruding part 4611, and the protruding part 4611 is matched with the limiting groove 451.

[0124] In one embodiment, a limiting groove 451 is defined on the first diagonal support rod 450, and a protrusion 4611 is provided on the clamp assembly 460. The protrusion 4611 cooperates with the limiting groove 451 to securely connect the clamp assembly 460 to the outer wall of the first diagonal support rod 450. Specifically, an annular limiting groove is defined on the outer wall of the first diagonal support rod 450, and an annular protrusion 4611 is provided on the inner wall of the clamp assembly 460. When the clamp assembly 460 is locked, the annular protrusion 4611 engages in the annular limiting groove to connect the clamp assembly 460 to the first diagonal support rod 450.

[0125] In another embodiment, a protrusion 4611 is provided on the first diagonal support rod 450, and a limiting groove 451 is opened on the clamp assembly 460. The protrusion 4611 cooperates with the limiting groove 451 to fix the clamp assembly 460 to the outer wall of the first diagonal support rod 450.

[0126] In some embodiments, first limiting teeth 471 are sequentially arranged along the axial direction on the outer wall of the second diagonal support rod 470, and second limiting teeth 4621 are sequentially arranged along the axial direction on the inner wall of the second clamp 462, and the first limiting teeth 471 and the second limiting teeth 4621 are engaged.

[0127] In this embodiment, when the second clamp 462 is tightly clamped onto the second diagonal support rod 470, the first limiting teeth 471 on the inner side of the second clamp 462 engage with the second limiting teeth 4621 on the second diagonal support rod 470, thereby locking the second diagonal support rod 470. Specifically, limiting racks are provided on two radially opposite sides of the second diagonal support rod 470, each of which includes a plurality of first limiting teeth 471 arranged in sequence along the axial direction. The first limiting teeth 471 are triangular teeth, and correspondingly, the second limiting teeth 4621 are also triangular teeth.

[0128] In some embodiments, the clamp assembly 460 includes a rotating shaft 463, a first locking bolt 464, and a second locking bolt 465. The first clamp 461 includes a first clamping segment 4612 and a second clamping segment 4613 arranged along the axial direction of the clamp assembly 460, and the first clamping segment 4612 covers the second clamping segment 4613. The first clamping segment 4612 and the second clamping segment 4613 are respectively provided with arc-shaped cavities with openings facing each other. The second clamp 462 includes a third clamping segment 4622 and a fourth clamping segment 4623 arranged along the axial direction of the clamp assembly 460. The third clamping segment 4622 covers the fourth clamping segment 4623, and the third clamping segment 4622 and the fourth clamping segment 4623 are respectively provided with arc-shaped cavities with openings facing each other; the rotating shaft 463 passes through the first clamping segment 4612, the second clamping segment 4613, the third clamping segment 4622 and the fourth clamping segment 4623 in sequence along the axial direction of the clamp assembly 460, and the first locking bolt 464 is used to lock the first clamping segment 4612 on the second clamping segment 4613, and the second locking bolt 465 is used to lock the third clamping segment 4622 on the fourth clamping segment 4623.

[0129] In this embodiment, the first, second, third, and fourth gripping sections 4612, 4613, 4622, and 4623 are sequentially connected via a rotational axis 463, enabling the first gripping section 4612 to rotate relative to the second gripping section 4613, thereby opening or closing over the second gripping section 4613. When the first gripping section 4612 is closed over the second gripping section 4613, the arcuate cavity in the first gripping section 4612 and the arcuate cavity in the second gripping section 4613 merge into a circular through-hole, facilitating gripping of the first diagonal brace 450. The first and second gripping sections 4612, 4613 can be locked together using a first locking bolt 464.

[0130] Specifically, the inner diameter of the arc-shaped cavity on the first clamping section 4612 is smaller than the inner diameter of the arc-shaped cavity on the second clamping section 4613, which is equivalent to providing a protrusion 4611 in the first clamping hoop 461, so that the first clamping hoop 461 can cooperate with the limiting groove 451 on the first diagonal support rod 450 to limit the axial movement of the first clamping hoop 461 through the limiting groove 451.

[0131] Similarly, the first, second, third, and fourth gripping segments 4612, 4613, 4622, and 4623 are sequentially connected via a rotational axis 463, enabling the third gripping segment 4622 to rotate relative to the fourth gripping segment 4623, thereby opening or closing over the fourth gripping segment 4623. When the third gripping segment 4622 is closed over the fourth gripping segment 4623, the arcuate cavity in the third and fourth gripping segments 4622 and 4623 merges into a circular through-hole, facilitating gripping of the second diagonal brace 470. The third and fourth gripping segments 4622 and 4623 can be locked together using a second locking bolt.

[0132] The first locking bolt 464 and the second locking bolt 465 are sequentially arranged along the circumference of the clamp assembly 460 , and the first locking bolt 464 is located at one end of the rotating shaft 463 along the radial direction of the clamp assembly 460 .

[0133] Furthermore, the clamp assembly 460 includes a first connecting shaft 466 and a second connecting shaft 467 spaced apart along the axial direction of the first clamping segment 4612. The first connecting shaft 466 sequentially passes through the first clamping segment 4612 and the third clamping segment 4622 along the axial direction of the clamp assembly 460, and the second connecting shaft 467 sequentially passes through the second clamping segment 4613 and the fourth clamping segment 4623 along the axial direction of the clamp assembly 460.

[0134] In this embodiment, the first clamping segment 4612, the second clamping segment 4613, the third clamping segment 4622 and the fourth clamping segment 4623 are connected in sequence through the rotating shaft 463. At the same time, the first connecting shaft 466 connects the first clamping segment 4612 and the third clamping segment 4622, and the second connecting shaft 467 connects the second clamping segment 4613 and the fourth clamping segment 4623, that is, the first connecting shaft 466 can increase the connection stability between the first clamping hoop 461 and the second clamping hoop 462.

[0135] In some embodiments, there are multiple diagonal bracing members 400 , and at least one diagonal bracing member 400 includes a tensioning assembly 420 and a locking assembly 430 .

[0136] In some embodiments, combined Figure 1 The support structure includes at least three non-collinear support rod assemblies 200, and the support frame 300 includes multiple cross beams 310 and multiple longitudinal beams 320. The cross beams 310 and the longitudinal beams 320 are staggered. The end of the mother support rod 210 of each support rod assembly 200 away from the sub-support rod 220 is connected to the base assembly 100, and the end of the sub-support rod 220 of each support rod assembly 200 away from the mother support rod 210 is fixedly connected to the support frame 300.

[0137] In the embodiment, the photovoltaic power station comprises a plurality of photovoltaic assemblies 500 connected in series or in parallel. The plurality of photovoltaic assemblies 500 are arranged in sequence on the support frame 300. Specifically, each support frame 300 can be supported by three or more support rod assemblies 200. When the number of support rod assemblies 200 is three, the three support rod assemblies 200 are not collinear, i.e., arranged in a triangular shape, to achieve stable support of the support frame 300.

[0138] For example, the number of support rod assemblies 200 is four, and the support rod assemblies 200 are respectively arranged at the four corners of the support frame 300. The heights of the four support rod assemblies 200 can be adjusted respectively to ensure that the support frame 300 is in a plane, and each support rod assembly 200 is rotatably connected with the base assembly 100 to facilitate installation of the support rod assembly 200 on a rolling mountain.

[0139] In some embodiments, in combination Figures 19-23 The cross beam 310 comprises a first side wall 311 and a second side wall 312 arranged opposite in the second direction, and a connecting wall 313 connecting the first side wall 311 and the second side wall 312. The two ends of the first side wall 311 and the second side wall 312 in the first direction are respectively bent towards the inner walls close to each other to form a first bent portion 314.

[0140] The cross beam 310 is fixedly connected with the frame 510 of the photovoltaic assembly 500 in the first direction through a first fastening assembly 340, and the other end of the cross beam 310 in the first direction is fixedly connected with the longitudinal beam 320 through a second fastening assembly 350. The first fastening assembly 340 comprises a first pressing block 341 and a first fastening bolt 342. The two ends of the first pressing block 341 are respectively overlapped on the two first bent portions 314 at one end of the cross beam 310 in the first direction, and the first fastening bolt 342 is sequentially fixedly connected with the frame 510 of the photovoltaic assembly 500 through the first pressing block 341.

[0145] In another embodiment, the support structure is a separate support structure. Specifically, the base assembly 100, the support rod assembly 200, and the support frame 300 are provided in a one-to-one correspondence. In this case, the support frame 300 can be rotatably connected to the mother support rod 210. During installation, the support frame 300 can be rotated as needed to align the photovoltaic assembly 500 with the target illumination direction, and then the support frame 300 can be fixed.

[0146] Specifically, the support structure includes a base assembly 100, a support rod assembly 200, and a support frame 300. The base assembly 100 is fixed to any plane or inclined surface; the support rod assembly 200 includes a mother support rod 210, a sub-support rod 220, and a locking mechanism 230. The sub-support rod 220 is partially inserted into the mother support rod 210, and the insertion depth can be adjusted. The locking mechanism 230 is arranged between the sub-support rod 220 and the mother support rod 210 in the radial direction to lock the two. The end of the mother support rod 210 away from the sub-support rod 220 is connected to the base assembly 100. The support frame 300 is used to install the photovoltaic module 500 and is arranged at the end of the sub-support rod 220 away from the mother support rod 210. The base assembly 100, the support rod assembly 200, and the support frame 300 are arranged in a one-to-one correspondence.

[0147] In some embodiments, the support rod group includes a triangular support rod, one of the vertices of the triangular support rod is rotatably connected to the sub-support rod 220, and the other two vertices of the triangular support rod are fixedly connected to the longitudinal beam 320.

[0148] In one embodiment of the present application, a photovoltaic power station is further disclosed. The photovoltaic power station includes a photovoltaic module 500 and the above-mentioned support structure. The photovoltaic module 500 is arranged on a support frame 300 .

[0149] The support structure of the present application can be used to build stable photovoltaic power stations in extremely complex landforms such as desertification and karst. Among them, the base assembly 100 is used to provide a stable initial support point on the concave and convex surface of the rock. The support rod assembly 200 can freely adjust the height to accurately cope with the height difference of the terrain and ensure that the component installation plane is level. The diagonal bracing members can be tensioned to eliminate all structural voids and make the entire support system rigidly connected and integrated. In addition, the diagonal bracing members can be flexibly telescopically adjusted to provide strong lateral support for high-drop columns, so as to ultimately achieve a firm, reliable and efficient installation of the support structure on rugged terrain.

[0150] Of course, the present application is not only applicable to support structures for extreme terrains. Due to its easy installation and disassembly, high adaptability, and stable structure, the support structure of the present application can also be widely used in other fields. For example: in the field of construction engineering, the support structure of the present application can be used as a temporary / permanent support structure for complex terrain; in the field of transportation facilities, the support structure of the present application can be used as slope protection, temporary bridges, and maintenance platform supports; in the field of stage performances, the support structure of the present application can be used for the rapid and stable construction of large stages and lighting racks in rugged venues; in the field of medical emergencies, the support structure of the present application can be used for stable support systems for temporary medical facilities and tents in the wild; in short, the support structure of the present application can be used in any occasion where a stable scaffolding structure needs to be quickly established in a complex terrain environment.

[0151] An embodiment of the present application further discloses a method for installing the above-mentioned bracket structure, the installation method comprising the following steps:

[0152] Install the base: Install the base assembly 100 on any flat or inclined surface;

[0153] Install the mother support rod 210: Rotate and connect the mother support rod 210 to the base assembly 100, adjust the mother support rod 210 to the target angle, and then fix the mother support rod 210;

[0154] Install the sub-strut 220: Insert part of the sub-strut 220 into the mother strut 210, and position the clamping mechanism 240 between the sub-strut 220 and the mother strut 210. Adjust the height of the sub-strut 220 to the target height of the support rod assembly 200, and secure the sub-strut 220 with the locking assembly.

[0155] Installing the support frame 300 : Installing the support frame 300 and the photovoltaic assembly 500 on the sub-support poles 220 .

[0156] It should be noted that the above steps do not limit the order of the steps. For example, after the base is installed, the sub-support rod 220 can be installed on the mother support rod 210 first, and then the support rod assembly 200 consisting of the sub-support rod 220 and the mother support rod 210 can be installed on the base; or after the base is installed, the mother support rod 210 can be installed on the base first, and then the sub-support rod 220 can be installed on the mother support rod 210.

[0157] In this embodiment, the support rods are rotatably connected to the base assembly 100 and are angle-adjustable, allowing the base assembly 100 to be installed on any flat or inclined surface. This eliminates terrain restrictions and reduces the complexity and cost of modifying the base 110. Furthermore, the sub-support rods 220 can be adjusted to a target height, allowing the support structure to precisely adjust the orientation and tilt angle of the photovoltaic assembly 500 based on the lighting conditions of different regions and specific installation environments, thereby maximizing solar radiation reception and improving photovoltaic power generation efficiency.

[0158] Specifically, under normal circumstances, the support rod assembly 200 needs to be arranged in a vertical direction to support the support frame 300. The target angle is the angle between the current extension direction of the mother support rod 210 and the vertical direction. Of course, in some special cases, for example, the mountain structure directly below one of the corners of the support frame 300 is complex, making it inconvenient to install the base assembly 100. In this case, the bottom of the corner of the support frame 300 can be located at a convenient position for installing the base assembly 100, and the support rod assembly 200 can be tilted. In this case, the target angle is the angle between the extension direction of the mother support rod 210 and the tilt direction.

[0159] In some embodiments, the photovoltaic assembly 500 includes at least three non-collinear support rod assemblies 200; the specific steps of adjusting the height of the sub-support rod 220 to the target height of the support rod assembly 200 include:

[0160] Determine the plane of the photovoltaic assembly 500 according to the height and inclination of the photovoltaic assembly 500;

[0161] Each sub-strut 220 is adjusted in sequence until the top of the sub-strut 220 is located in the plane. The height of the support rod assembly 200 corresponding to the top of the sub-strut 220 being located in the plane is the target height.

[0162] In this embodiment, the length of each support rod assembly 200 is adjustable. When the support frame 300 is supported by multiple support rod assemblies 200, each support rod assembly 200 can be adjusted one by one according to the different heights of each support rod assembly 200, so that the tops of all support rod assemblies 200 are in the plane where they are located, that is, they can provide stable and effective support for the photovoltaic assembly 500.

[0163] In some embodiments, the installation method further comprises:

[0164] Rotate the second rotating portion 424 of the tensioning assembly 420 to connect with the support rod assembly 200;

[0165] One end of the diagonal brace assembly is rotatably connected to the support frame 300, and the other end is rotatably connected to the first rotating portion of the tensioning assembly 420;

[0166] Rotate the tensioning assembly 420 to tension the diagonal brace assembly;

[0167] The tensioning assembly 420 is fixed by the locking assembly 430 .

[0168] In this embodiment, by rotating and connecting the tensioning assembly 420 to the support rod assembly 200 and the diagonal brace rod group respectively, and then using the tensioning assembly 420 to tension and fix the diagonal brace rod group, a triangular reinforcement structure is formed. This design can effectively disperse and withstand external forces from different directions, greatly enhancing the overall structural strength of the support structure, so that it can remain stable even in severe weather and complex environments, and reducing the risk of deformation and collapse of the support. In addition, after the diagonal brace rod group is tensioned, the shaking and displacement of the support structure can be effectively suppressed in windy weather. When wind acts on the photovoltaic assembly 500, the tensioned diagonal brace rod group can promptly decompose and transmit the force generated by the wind, avoiding damage to the support due to wind impact, improving the safety and reliability of the photovoltaic system in strong wind environments, and reducing equipment damage and power generation losses caused by wind disasters.

[0169] Among them, the tensioning assembly 420 in this embodiment is not limited to using the above-mentioned lever arm, but can also be a telescopic structure set at one end of the diagonal support rod group. When the telescopic structure is extended or retracted, the diagonal support rod group can be tensioned or relaxed.

[0170] In some embodiments, before installing the base assembly 100, the method further includes:

[0171] Find a suitable surface location for installing the base assembly 100 based on the size of the photovoltaic assembly 500, and chisel out a hard surface at the installation location of the base assembly 100 to securely install expansion screws;

[0172] The base 110 is then installed on the ground surface using expansion screws.

[0173] When searching for a suitable surface location for installing the base assembly 100, if the rock surface is cracked or weathered, a 10mm-20mm thick layer of epoxy resin mortar is applied to restore its hardness. If the weathering is severe, expansion screws are used as anchors for reinforcement. A pull-out test is then performed to ensure that the interface hardness meets ≥2.5MPa. When securing with expansion screws, apply thread sealant to the threads of the expansion screws and add a lock washer before tightening. Then, apply thread sealant to the entire expansion screw to extend the life of the component and prevent it from loosening.

[0174] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0175] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
