Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel support technology, and in particular to a photovoltaic panel support structure and method based on windbreak and sand control. Background Art

[0002] Photovoltaic support structures are the core supporting structures in solar photovoltaic power generation systems. Their main functions are to fix and install solar panels and ensure that they maintain optimal tilt angle and stability under various environmental conditions. The support frame is usually composed of columns, main beams and diagonal braces made of carbon steel or aluminum alloy to form the main load-bearing structure. The connecting components include high-strength bolts, special pressure blocks and hinge mechanisms to achieve reliable fixing between the photovoltaic panels and the support structure. The fixed foundation is selected from concrete bases or prestressed helical piles according to geological conditions to ensure overall stability.

[0003] However, the following problems exist in the installation and use of photovoltaic panel supports: First, traditional purlins are usually directly fixed to the main beam or guide rail with simple bolts. The purlins are fixed at independent points, and the purlins are fixed to the main structure. When encountering strong winds, the wind force will be concentrated on these independent fixed points, which can easily cause the bolts at the connection to loosen, deform or even break. The entire support system lacks an effective force transmission path and cannot effectively distribute the wind load borne locally to the entire structural system. Second, each row of supports is an independent, self-supporting unit without connection, and adjacent supports cannot share any force with it.

[0004] Therefore, the cumbersome bracket fixing method and the poor overall stability of the structure after fixing, which affect the wind resistance reliability of the system, are technical problems that need to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the above problems, embodiments of the present invention provide a photovoltaic panel support structure and method based on windbreak and sand control to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The first aspect of the present invention provides a photovoltaic panel support structure based on windbreak and sand control, including multiple sets of support components distributed longitudinally. Each set of support components consists of two symmetrical bases. A horizontal bar is obliquely installed on the two bases in the same set through a fixing part. Multiple purlins are provided on the upper end of the horizontal bar. The purlins are fixedly installed on the horizontal bar through a locking mechanism. A traction mechanism is provided between two adjacent supports on the left and right sides.

[0007] The locking mechanism includes slots opened at the upper ends of the crossbars and purlins. Both the crossbars and purlins are square tube structures. The slots are connected to the inner cavities of the corresponding crossbars and purlins. A connecting block located inside the crossbar is fixedly installed at the lower end of the purlin. An isosceles trapezoidal limiting block is fixedly installed at the lower end of the connecting block. An extrusion block located between two adjacent limiting blocks is slidably installed inside the crossbar. Fixing blocks are provided at both the left and right ends of the crossbar.

[0008] The traction mechanism includes steel cables, and multiple steel cables are connected between the fixing blocks on the right side of two adjacent sets of supports.

[0009] The wedge-shaped self-locking cooperation between the limiting block, the fixing block, and the squeezing block enables the purlin to be continuously and linearly fixed on the crossbar, establishing a longitudinal force transmission path. At the same time, the steel cables interconnect adjacent supports, constructing a transverse load distribution mechanism, so that multiple rows of supports form a spatially coordinated force-bearing overall structure.

[0010] As a preferred embodiment, the traction mechanism further includes guide components that correspond one-to-one with the steel cables and are used to guide the steel cables. Each guide component consists of two No. 2 guide wheels. One No. 2 guide wheel is rotatably mounted on the upper end of the corresponding base on the right side of a bracket via a No. 2 shaft seat. The other No. 2 guide wheel is also rotatably mounted on the upper end of the corresponding base on the right side of an adjacent bracket via a No. 2 shaft seat. A No. 1 guide wheel is rotatably mounted on the upper end of the base on the left side via a No. 1 shaft seat. The No. 1 guide wheel is higher than the No. 2 guide wheels. The two ends of the steel cable pass through the No. 2 guide wheels on the corresponding brackets from the corresponding No. 1 guide wheels and are connected to the corresponding fixing blocks through the connecting parts.

[0011] As a preferred embodiment, the fixing part includes a column fixedly installed on the upper end of the base; on the two bases in the same group, the left column is higher than the right column, and a horizontal bar is fixedly installed on both columns. A reinforcing beam is installed obliquely between the right end of the left column and the lower end of the corresponding horizontal bar, and the three form a stable triangular structure.

[0012] As a preferred embodiment, the connecting part includes a fixing post fixedly installed on the right side of the fixing block near the horizontal bar. After the fixing post slides through the horizontal bar, a fixing plate is fixedly installed together. The side of the fixing plate away from the fixing post is fixedly connected to the end of the steel cable corresponding to the fixing post.

[0013] As a preferred embodiment, the limiting block is an isosceles trapezoidal structure with an upper area smaller than the lower area, and the left and right ends of the lower part of the extrusion block and the end of the fixing block near the limiting block are provided with wedge-shaped surfaces that cooperate with the inclined surfaces on the limiting block.

[0014] As a preferred embodiment, the extrusion block has two symmetrical waist grooves, and guide posts corresponding to the waist grooves are fixedly installed on the horizontal bar, with the guide posts sliding through the corresponding waist grooves.

[0015] As a preferred embodiment, the fixing block on the left is fixedly installed inside the horizontal bar, while the fixing block on the right is detachably installed inside the horizontal bar.

[0016] As a preferred embodiment, the fixing block on the right side is slidably installed inside the crossbar, and a bolt is threaded onto the crossbar, with the bolt thread penetrating the fixing block on the right side.

[0017] As a preferred embodiment, a pair of limiting posts are fixedly installed at the lower end of the limiting block, and the horizontal bar has waist-shaped holes that slide and engage with the limiting posts one by one.

[0018] The second aspect of the present invention provides a photovoltaic panel support installation method based on windbreak and sand control, which is completed by using a photovoltaic panel support based on windbreak and sand control, including the following steps: S1, fixing a column at the upper end of the base and installing a horizontal bar at the upper end of the column.

[0019] S2. Insert the limiting block on the purlin into the crossbar, and initially limit the movement by cooperating with the waist-shaped hole through the limiting post.

[0020] S3. The moving purlins continuously lock the limiting block and the pressing block in place.

[0021] S4. Insert the right-side fixing block, and fix it after its inclined surface fits against the limiting block.

[0022] S5. The tensioning of the steel cable enables the two adjacent sets of supports to bear the load together.

[0023] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: First, the present invention, through the coordinated design of locking and traction mechanisms, systematically solves the core problems of easy failure of traditional point-fixed supports and the inability of isolated supports to cooperate in wind resistance. The locking mechanism connects the purlins into a whole to optimize longitudinal force transmission; the traction mechanism interconnects adjacent supports through steel cables to construct a lateral load transmission path, greatly improving the overall stability and reliability of the array in windy and sandy environments.

[0024] Second, this invention achieves rapid installation of purlins through wedge-shaped self-locking between the limiting block, the pressing block, and the fixing block, transforming discrete point-based fixing into linear continuous fixing. This design not only simplifies installation but also ensures coordinated stress distribution among the purlins, effectively avoiding connection failures caused by single-point stress concentration and enhancing the longitudinal stability of single-row supports.

[0025] Third, this invention connects the fixing blocks of adjacent supports with steel cables, thus forming a mechanical connection between the originally independent support units. The lateral constraint and prestress provided by the tension of the steel cables can effectively transfer and distribute the wind load acting on the local support to the adjacent supports for joint bearing, changing the individual bearing to the overall bearing, solving the defects of the lack of connection between supports and the inability to cooperate in wind resistance, and improving the overall wind resistance of the array.

Detailed Implementation

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the photovoltaic panel support structure based on windbreak and sand control includes multiple sets of support components distributed longitudinally. Each set of support components consists of two symmetrical bases 10. A horizontal bar 12 is installed obliquely on the two bases 10 in the same set through a fixing part 11. Multiple purlins 13 are provided on the upper end of the horizontal bar 12. The purlins 13 are fixedly installed on the horizontal bar 12 through a locking mechanism 2. A tensioning mechanism 3 is provided between two adjacent supports on the left and right.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, the locking mechanism 2 includes slots opened at the upper ends of the horizontal bar 12 and the purlin 13. Both the horizontal bar 12 and the purlin 13 are square tube structures. The slots are connected to the inner cavities of the corresponding horizontal bar 12 and the purlin 13. A connecting block 20 located inside the horizontal bar 12 is fixedly installed at the lower end of the purlin 13. An isosceles trapezoidal limiting block 21 is fixedly installed at the lower end of the connecting block 20. An extrusion block 22 located between two adjacent limiting blocks 21 is slidably installed in the inner cavity of the horizontal bar 12. Fixing blocks 23 are provided at both the left and right ends of the horizontal bar 12. The limiting block 21 is wedge-shapedly engaged with the extrusion block 22 and the fixing block 23.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the fixing part 11 includes a column 110 fixedly installed on the upper end of the base 10; on the two bases 10 in the same group, the left column 110 is higher than the right column 110, and a horizontal bar 12 is fixedly installed on both columns 110. A reinforcing beam 111 is installed obliquely between the right end of the left column 110 and the lower end of the corresponding horizontal bar 12, and the three form a stable triangular structure.

[0040] like Figure 1 , Figure 3 and Figure 5 As shown, the traction mechanism 3 includes steel cables 30, and multiple steel cables 30 are connected between the fixing blocks 23 on the right side of two adjacent sets of supports.

[0041] like Figure 2 , Figure 3 and Figure 4As shown, a pair of limiting posts 24 are fixedly installed at the lower end of the limiting block 21, and the horizontal bar 12 has waist-shaped holes that slide and cooperate with the limiting posts 24 one by one.

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the extrusion block 22 has two symmetrical waist grooves 220, and the crossbar 12 is fixedly installed with guide posts 221 corresponding to the waist grooves 220, and the guide posts 221 slide through the corresponding waist grooves 220.

[0043] like Figure 2 , Figure 3 and Figure 4 As shown, the fixing block 23 on the left is fixedly installed inside the horizontal bar 12, and the fixing block 23 on the right is detachably installed inside the horizontal bar 12.

[0044] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the fixing block 23 on the right side is slidably installed inside the horizontal bar 12, and the horizontal bar 12 is threaded with a bolt 230, the bolt 230 threaded through the fixing block 23 on the right side.

[0045] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the limiting block 21 is an isosceles trapezoidal structure with an upper area smaller than the lower area. The left and right ends of the lower part of the squeezing block 22 and the end of the fixing block 23 near the limiting block 21 are all provided with wedge-shaped surfaces that cooperate with the inclined surface on the limiting block 21.

[0046] like Figures 1 to 7 As shown, in specific operations, a base 10 of the required height is first poured with concrete at the designed location. After the base 10 has solidified, the uprights 110 are fixedly installed on the upper end of the base 10. Then, the horizontal bars 12 are installed obliquely on the upper ends of the two uprights 110 in the same group. Next, the purlins 13 are installed sequentially from top to bottom, so that the connecting blocks 20 and limiting blocks 21 on the purlins 13 are inserted into the corresponding horizontal bars 12, and the limiting posts 24 are inserted into the corresponding oblong holes to restrict the forward and backward movement of the purlins 13. Then move the purlin 13 to the left so that the inclined surface on the left side of the limiting block 21 fits into the wedge-shaped surface of the left fixing block 23. Then install the next purlin 13. The leftward movement of the purlin 13 pushes the previous purlin 13 and the pressing block 22 on it to the left. Through the cooperation of the guide post 221 and the waist groove 220, the movement direction of the pressing block 22 is guided. The left wedge-shaped surface of the pressing block 22 fits into the right inclined surface of the limiting block 21 on the previous purlin 13, thereby fixing the previous purlin 13.

[0047] After installing the last purlin 13 according to the above operation, slide the right fixing block 23 onto the right end of the crossbar 12 and push the right fixing block 23 to the left so that the wedge-shaped surface of the right fixing block 23 fits against the right inclined surface of the last limiting block 21. Then fix the right fixing block 23 with bolts 230, thereby quickly and stably installing the purlin 13 onto the crossbar 12 according to the above operation.

[0048] Then, the purlins 13 that were last installed on the two supports are connected to each other by steel cables 30. The steel cables 30 are flexible components that generate strong tension when stretched. The deformation of the wind-exposed support will stretch the steel cables 30, and the tension of the steel cables 30 will increase with the stretching, thereby applying a reverse constraint force to the wind-exposed support. At the same time, this tension also acts on the adjacent supports that are not directly exposed to the wind, so that they also participate in the work. In this way, the load that was originally borne by one row alone is redistributed to multiple rows of supports to share the burden.

[0049] In addition, the design of the support structure provides sufficient working space for subsequent planting of grass and fixing sand under the board, and the steel cables 30 of the traction mechanism 3 connect adjacent supports to form an overall network. This network structure can not only effectively distribute wind load, but also form a stable windbreak system in the sandy environment, reduce wind speed, reduce the damage of wind and sand flow to the vegetation under the board, and create a suitable microclimate environment for the growth of vegetation under the board, which is conducive to the growth of sand-fixing plants, thus realizing the organic combination of photovoltaic power generation and desertification control.

[0050] like Figure 1 , Figure 5 and Figure 6 As shown, the traction mechanism 3 also includes a guide assembly corresponding to the steel cable 30 and used to guide the steel cable 30. Each guide assembly consists of two second guide wheels 32. One second guide wheel 32 is rotatably mounted on the upper end of the corresponding base 10 on the right side of a bracket via a second shaft seat. The other second guide wheel 32 is also rotatably mounted on the upper end of the corresponding base 10 on the right side of an adjacent bracket via a second shaft seat. A first guide wheel 31 is rotatably mounted on the upper end of the base 10 on the left side via a first shaft seat. The first guide wheel 31 is higher than the second guide wheel 32. The steel cable 30 passes over the second guide wheel 32 on the corresponding bracket from the corresponding first guide wheel 31 and is connected to the corresponding fixing block 23 through the connecting part 4.

[0051] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the connecting part 4 includes a fixing post 40 fixedly installed on the right side of the fixing block 23 near the horizontal bar 12. After the fixing post 40 slides through the horizontal bar 12, a fixing plate 41 is fixedly installed together. The side of the fixing plate 41 away from the fixing post 40 is fixedly connected to the end of the steel cable 30.

[0052] like Figures 1 to 6 As shown, during operation, the two ends of the steel cable 30 pass over the corresponding second guide wheel 32 in the two sets of supports, and then are fixedly connected to the lower end of the corresponding fixed plate 41 in the two sets of supports. Then, the first guide wheel 31 abuts against the middle of the steel cable 30, and the position of the first axle seat is adjusted to tension the steel cable 30. After that, the first axle seat is fixed on the corresponding base 10. At this time, the steel cable 30 strongly pulls the key nodes at the ends of the adjacent supports together. When any row is hit by strong winds, part of the load it bears can be immediately transferred through the steel cable 30 and distributed to the adjacent multiple rows of supports, and is borne by the entire array. This makes the wind resistance no longer determined by the weakest row, but by the overall strength of the entire system, and the safety is improved exponentially. In addition, the right-side fixed block 23 can be fixed a second time by the tension of the steel cable 30 to further ensure the stability of the connection between the purlin 13 and the crossbar 12.

[0053] In addition, the present invention also provides a photovoltaic panel support installation method based on windbreak and sand control, which is completed by using a photovoltaic panel support based on windbreak and sand control, including the following steps: S1, pour a concrete base 10 at the designed position, and after it solidifies, fix the column 110 on the upper end of the base 10, and then fix the horizontal bar 12 at an angle on the upper end of the two columns 110 in the same group.

[0054] S2. Insert the purlin 13 into the crossbar 12 through the connecting block 20 and the limiting block 21 at its lower end, and let the limiting post 24 at the lower end of the limiting block 21 slide into the waist-shaped hole on the crossbar 12. The sliding direction of the limiting post 24 is restricted by the waist-shaped hole, so that the limiting post 24 cannot move in the front-back direction, but can only move along the length direction of the waist-shaped hole (i.e., the left-right direction), thereby indirectly achieving the initial limiting of the purlin 13.

[0055] S3. Move the first purlin 13 to the left so that the inclined surface of its limiting block 21 fits against the wedge-shaped surface of the fixing block 23 at the left end of the crossbar 12; then install the next purlin 13, which pushes the pressing block 22 to move. The wedge-shaped surface on the pressing block 22 engages with the inclined wedge-shaped surface of the upper limiting block 21 of the previous purlin 13 to achieve continuous locking; install the remaining purlins 13 in this manner.

[0056] S4. After all purlins 13 are installed, insert the right-side fixing block 23 into the right end of the crossbar 12 and push it to the left so that its wedge-shaped surface fits against the inclined surface of the upper limit block 21 of the last purlin 13. Finally, tighten the right-side fixing block 23 with bolts 230.

[0057] S5. The steel cable 30 is passed around the guide wheels on the bases 10 of the two adjacent brackets, and its two ends are connected to the fixing plates 41 on the right side fixing blocks 23 of the two brackets respectively. By adjusting the tension of the steel cable 30 of the first shaft seat, the adjacent brackets are pulled together by the prestress of the steel cable 30 and connected as an integral load-bearing structure.
