A flexible support based photovoltaic power generation system

Abstract

This invention relates to a photovoltaic power generation system based on a flexible support structure, applicable to the field of photovoltaic power generation systems. Through the inclusion of a strength compensation unit, on the one hand, the verticality of the support column can be monitored in real time, allowing for timely detection of excessive deformation under stress. On the other hand, after deformation under stress, the two reinforcing strips in the strength compensation unit, under the deformation signal of the support column, can expand away from each other along the arrangement direction of multiple photovoltaic panels. Then, the reinforcing block longitudinally disintegrates and embeds itself between the two reinforcing strips, forming a stable lining within the support column. This effectively enhances the strength of the support column, effectively suppresses its deformation amplitude, and provides sufficient time for maintenance by personnel, thereby effectively overcoming the stability problems existing in photovoltaic equipment using flexible supports.

Description

Technical Field

[0001] This invention relates to a photovoltaic power generation system, and more particularly to a photovoltaic power generation system based on a flexible support structure applied in the field of photovoltaic power generation systems. Background Technology

[0002] Existing photovoltaic equipment is generally installed on the ground, roof, or other unobstructed surfaces using fixed brackets. However, this traditional installation method occupies a large area and requires a large number of positioning columns. On the one hand, it uses a lot of metal, resulting in high installation costs. On the other hand, due to the dense placement of positioning columns, the space under the photovoltaic panels is difficult to reuse.

[0003] To address the aforementioned issues, existing technologies have developed photovoltaic (PV) power generation equipment installed using flexible supports. This equipment is suspended between two support components by flexible cables, resulting in an overall suspended state. Examples include a flexible support distributed PV power generation system for wastewater treatment plants disclosed in Chinese Patent Publication No. CN217643281U, and a point-supported flexible cable PV support and its combined array disclosed in Chinese Patent Publication No. CN107181446A. Due to the relatively small number of positioning components, the space below is less affected by the positioning columns and can be reused. However, in this type of PV equipment installed using flexible cables, the span between the two positioning components is relatively large, making it susceptible to swaying due to natural wind forces. When the wind force is too strong, the support columns on the positioning components experience concentrated and significant stress, which can easily cause the support columns to tilt towards the center, affecting the stability of the PV equipment. Summary of the Invention

[0004] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that the span between the positioning columns is large, the force is relatively concentrated, and they are prone to tilting towards the photovoltaic panel side, which affects the stability of the entire photovoltaic system.

[0005] To address the aforementioned issues, this invention provides a photovoltaic power generation system based on a flexible support structure, comprising two sets of support components, two horizontal cables connecting the two sets of support components, and multiple photovoltaic panels evenly suspended between the two horizontal cables. The ends of the horizontal cables are fixedly connected to inclined cables, and the ends of the inclined cables are connected to a counterweight balancing component buried underground. The bottom of the multiple photovoltaic panels shares two long keels, and two T-shaped blocks corresponding to the two long keels are clamped between adjacent photovoltaic panels. The T-shaped blocks and the long keels are fixed together by bolts. The two horizontal cables are located at the vertical angle formed by the two long keels and the photovoltaic panels. Multiple evenly distributed binding straps are fixedly connected to the downward-sloping sides of the long keels, and the binding straps are tied to the outside of the horizontal cables.

[0006] The support assembly includes two columns, a support base fixedly connected to the upper ends of the two columns, and two double vertical angle steels fixedly connected to the upper ends of the support bases. The upper middle of the two double vertical angle steels is bolted to a support column. The end of the horizontal cable passes through the support column, and the end of the support column away from the photovoltaic panel is fastened to the horizontal cable with a locking device. A flat plate is fixedly connected to the inner wall of the upper end of the support column. A strength compensation unit is set inside the support column. The strength compensation unit includes a guide rod fixedly connected to the middle of the lower end of the flat plate, a reinforcing block set at the lower end of the flat plate, and two reinforcing strips located at the bottom of the support column. The reinforcing block is sleeved on the guide rod, and two limiting ropes are fixedly connected between the reinforcing block and the flat plate. The upper ends of the two reinforcing strips that are close to each other are chiseled with guide grooves, and the lower ends of the reinforcing block and the guide rod extend into the guide grooves.

[0007] In the aforementioned photovoltaic power generation system based on flexible supports, the strength compensation unit can monitor the verticality of the support column in real time, allowing it to be detected promptly when it deforms under excessive stress. Furthermore, after deformation, the strength compensation unit can spontaneously decompose to form an inner lining within the support column, thereby increasing its strength, effectively suppressing deformation, and providing sufficient time for maintenance.

[0008] As a further improvement of this application, the vertical section of the double vertical angle steel faces multiple photovoltaic panels, and the number of bolts used to fix the horizontal section of the double vertical angle steel away from the photovoltaic panels to the support base is greater than the number of bolts on the other side.

[0009] As a further improvement of this application, the reinforcing block includes an upper compensation block fixedly connected to the limiting rope, a lower compensation block located below the upper compensation block, and a lower extension shaft fixedly connected to the lower end of the lower compensation block. The upper compensation block, the lower compensation block, and the lower extension shaft all movably pass through the guide rod, and the lower end of the lower extension shaft abuts against the inner wall of the guide groove.

[0010] As a further improvement of this application, when both reinforcing strips are in contact with the inner wall of the support column, the distance between the two reinforcing strips is greater than the width of the lower compensation block and the upper compensation block. Electromagnetic plates are fixedly embedded inside the left and right ends of the support column. When energized, the electromagnetic plates generate magnetic attraction force on the reinforcing strips.

[0011] As a further improvement of this application, a sensing unit is installed at the bottom of the support column. The sensing unit includes a groove carved in the support column away from the bottom of the photovoltaic panel and a laser rangefinder installed in the groove. The laser rangefinder and the limiting rope are not on the same vertical plane.

[0012] As another improvement of this application, a moisture-wicking layer is laid at the bottom of the support column, the energizing circuit of the electromagnetic sheet is connected in series with two conductive contacts, the moisture-wicking layer is connected between the two conductive contacts, and a sensing unit is provided inside each support column and between it and the reinforcing strip.

[0013] As a further improvement to this application, the sensing unit includes a pre-crushing rod fixedly connected to the inner wall of the support column and a plurality of supplementary steel rods fixedly connected to the end of the reinforcing strip. The pre-crushing rod is wrapped with a flexible mesh sleeve. From a top view, the pre-crushing rod and the supplementary steel rods are misaligned. The pre-crushing rod is made of a hollow brittle material and is filled with water.

[0014] As a further improvement to this application, the pre-crushing rod and the replacement steel rod have the same diameter, and the replacement steel rod is a rigid fixed structure. The replacement steel rod includes two end fixed sections, a through rod fixedly connected between the two end fixed sections, and a micro-moving section movably sleeved outside the through rod. The adjacent end fixed sections and micro-moving sections are in contact with each other, and the diameter of the through rod is smaller than the inner diameter of the micro-moving section.

[0015] In summary, by setting up the strength compensation unit, on the one hand, the verticality of the support column can be monitored in real time, so that it can be detected in time when it is over-deformed under stress. On the other hand, after deformation under stress, the two reinforcing strips in the strength compensation unit can expand away from each other along the arrangement direction of multiple photovoltaic panels under the deformation signal of the support column. Then the reinforcing block disintegrates longitudinally and is embedded between the two reinforcing strips, so that the reinforcing strips and reinforcing blocks form a stable lining inside the support column, thereby effectively enhancing the strength of the support column, effectively suppressing its deformation amplitude, providing sufficient time for maintenance by the staff, and thus effectively overcoming the stability problem of photovoltaic equipment with flexible support.

[0032] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0033] First implementation method:

[0034] Figures 1-3 A photovoltaic power generation system based on a flexible support structure is shown, including two sets of support components, two horizontal cables 4 connected between the two sets of support components, and multiple photovoltaic panels 3 evenly suspended between the two horizontal cables 4. The ends of the horizontal cables 4 are fixedly connected to inclined cables 402, and the ends of the inclined cables 402 are connected to a counterweight balancing component. The counterweight balancing component is buried underground. The counterweight balancing component is prior art and is not considered a technical point of this solution, so it is not described in detail.

[0035] like Figure 4Multiple photovoltaic panels 3 are provided with two long keels 302 at their bottom. Two T-shaped blocks 301, corresponding to the two long keels 302, are clamped between two adjacent photovoltaic panels 3. The T-shaped blocks 301 and the long keels 302 are fixed together by bolts. Two horizontal cables 4 are located at the lower vertical angle formed by the two long keels 302 and the photovoltaic panels 3. Multiple evenly distributed binding straps 303 are fixedly connected to the downward inclined side ends of the long keels 302. The multiple binding straps 303 are tied to the outside of the horizontal cables 4. The T-shaped blocks 301 and the long keels 302 can connect multiple photovoltaic panels 3 into one, and also create a stepped vertical groove on the back of the inclined photovoltaic panels 3, so that multiple photovoltaic panels 3 can be clamped on the two horizontal cables 4 at the same time. Then, the horizontal cables 4 can be tied together by the multiple binding straps 303, thereby ensuring the connection stability between the photovoltaic panels 3 and the horizontal cables 4.

[0036] like Figure 5 The support assembly includes two columns 1, a support base 21 fixedly connected to the upper end of the two columns 1, and two double vertical angle steels 23 fixedly connected to the upper end of the support base 21. The upper middle part of the two double vertical angle steels 23 is bolted to a support column 22. The end of the horizontal cable 4 movably passes through the support column 22, and the end of the support column 22 away from the photovoltaic panel 3 is fastened to the horizontal cable 4 with a locking member 401. The locking member 401 is used to restrict the position of the horizontal cable 4, making it difficult for it to pass through the support column 22 and making it less likely to slide laterally, thereby improving the stability of the multiple photovoltaic panels 3 loaded on it. The two support columns 22 have different heights, which in turn makes the two horizontal cables 4 between the two support assemblies have different heights, causing the photovoltaic panels 3 placed on them to be tilted.

[0037] The vertical section of the double vertical angle steel 23 faces multiple photovoltaic panels 3, and the number of bolts used to fix the horizontal section of the double vertical angle steel 23 away from the photovoltaic panels 3 to the support base 21 is greater than the number of bolts on the other side. In windy weather or during long-term use, due to the gravity of multiple photovoltaic panels 3, the support column 22 on the side away from the photovoltaic panels 3 tends to tilt when subjected to force. At this time, more fastening bolts are set on the corresponding side of the double vertical angle steel 23 to improve the connection strength and reduce its tilting amplitude.

[0038] like Figure 6 A flat plate 201 is fixedly connected to the inner wall of the upper end of the support column 22, and the flat plate 201 is parallel to the bottom of the support column 22. A strength compensation unit is provided inside the support column 22, such as... Figure 9The strength compensation unit includes a guide rod 8 fixedly connected to the middle of the lower end of the plate 201, a reinforcing block 6 set at the lower end of the plate 201, and two reinforcing strips 5 located at the bottom of the support column 22. The reinforcing block 6 includes an upper compensation block 61 fixedly connected to the limiting rope 601, a lower compensation block 62 located below the upper compensation block 61, and a lower extension shaft 63 fixedly connected to the lower end of the lower compensation block 62. The upper compensation block 61 and the lower compensation block 62 are both made of high-density, high-hardness metal materials, which makes them have a larger weight in the same volume and high hardness, making them less prone to deformation under stress, thus improving the reinforcement effect on the support column 22. The upper compensation block 61, the lower compensation block 62, and the lower extension shaft 63 all movably pass through the guide rod 8, and the lower end of the lower extension shaft 63 is connected to the guide rod 8. The inner wall of the guide groove 501 abuts against each other, so that when the two reinforcing strips 5 are not separated, the reinforcing block 6 can be stable under the restriction of the reinforcing strips 5, and is not easy to disintegrate prematurely. This facilitates the subsequent stable entry between the two reinforcing strips 5. The reinforcing block 6 is sleeved on the outside of the guide rod 8, and two limiting ropes 601 are fixedly connected between the reinforcing block 6 and the plate 201. The upper ends of the two reinforcing strips 5 that are close to each other are chiseled with guide grooves 501. The lower ends of the reinforcing block 6 and the guide rod 8 extend into the guide grooves 501. The guide rod 8 is used for guidance, so that the reinforcing block 6 can move smoothly down along the guide rod 8 after disintegration and fall stably between the two reinforcing strips 5, thereby restricting the position of the two reinforcing strips 5 and thus effectively ensuring the reinforcement of the support column 22 by the strength compensation unit.

[0039] It is worth noting that when the limiting rope 601 is fully extended, the upper compensation block 61 is lower than the guide groove 501, thus effectively ensuring that the upper compensation block 61 can be stably embedded between the two reinforcing strips 5. Furthermore, the upper compensation block 61 will fall to the bottom, while under the restriction of the limiting rope 601, the upper compensation block 61 is located slightly above, which can further improve the stability of the reinforcing strips 5 after the reinforcing block 6 is disassembled, and maintain a good reinforcing effect on the support column 22.

[0040] like Figure 6 A sensing unit is installed at the bottom of the support column 22. The sensing unit includes a groove carved into the bottom of the support column 22 away from the bottom of the photovoltaic panel 3 and a laser rangefinder 7 installed in the groove. The laser rangefinder 7 and the limiting rope 601 are not on the same vertical plane. Under normal circumstances, the laser beam emitted by the laser rangefinder 7 falls directly on the flat plate 201. When the support column 22 is not deformed, its force data is stable. When deformation occurs, the support column 22 will shift towards the photovoltaic panel 3. At this time, the flat plate 201 will also shift to a certain extent, causing it to no longer be parallel to the bottom of the support column 22, which in turn causes the laser rangefinder 7 to show obvious data changes.

[0041] When both reinforcing strips 5 are in contact with the inner wall of the support column 22, the distance between the two reinforcing strips 5 is greater than the width of the lower compensation block 62 and the upper compensation block 61, and the span difference between them does not exceed 5mm. This facilitates the reinforcing block 6 to smoothly enter between the two reinforcing strips 5 after disassembly, and prevents the situation where it is difficult to move down due to excessive friction with the reinforcing strips 5. At the same time, it provides a certain margin for the slight deformation of the reinforcing strips 5, so that the reinforcing block 6 is not difficult to enter between the two reinforcing strips 5 after disassembly due to such deformation. Electromagnetic plates are fixedly embedded inside the left and right sides of the support column 22. Figures 7-8 When the electromagnetic plate is energized, it generates a magnetic attraction force on the reinforcing strip 5. When the data on the laser rangefinder 7 fluctuates, it indicates that the support column 22 is deformed. The electromagnetic plate is then immediately energized, so that the two reinforcing strips 5 are separated as soon as the deformation trend begins. This allows the reinforcing block 6 to be easily embedded between the two reinforcing strips 5 after disassembly, thereby forming a stable lining between the reinforcing strips 5 and the reinforcing block 6 within the support column 22, making it less likely for the support column 22 to continue to deform.

[0042] It is worth noting that, in order to reduce the interference of the electromagnetic sheet on the other reinforcing strip 5 after it is energized, magnetic shielding material can be embedded inside the reinforcing strip 5 so that the reinforcing strip 5 is only controlled by the electromagnetic sheet on the same side. At the same time, magnetic patches are fixedly connected to the ends of the two reinforcing strips 5 that are close to each other, so that in the initial state, the two reinforcing strips 5 can attract each other and temporarily become one, which is convenient for temporarily limiting the position of the reinforcing block 6.

[0043] In addition, in order to reduce the impact of the electromagnetic sheet on the current transport generated in this photovoltaic system, magnetic shielding design can be carried out on the outside of the support column 22 as needed.

[0044] In summary, by setting up the strength compensation unit, on the one hand, the verticality of the support column 22 can be monitored in real time, so that it can be detected in time when it is subjected to excessive deformation. On the other hand, such as Figures 10-11 After being deformed under stress, the two reinforcing strips 5 in the strength compensation unit can expand away from each other along the arrangement direction of multiple photovoltaic panels 3 under the deformation signal of the support column 22. Then, the reinforcing block 6 disintegrates longitudinally and is embedded between the two reinforcing strips 5, so that the reinforcing strips 5 and the reinforcing block 6 form a stable lining in the support column 22, thereby effectively enhancing the strength of the support column 22, effectively suppressing its deformation amplitude, providing sufficient time for maintenance by the staff, and thus effectively overcoming the stability problem of photovoltaic equipment with flexible support.

[0045] Second implementation method:

[0046] This embodiment is based on the first embodiment, but provides another sensing unit and its related structure, while the rest remains the same as the first embodiment.

[0047] A moisture-wicking layer made of absorbent material is laid at the bottom of the inner part of the support column 22. The electromagnetic plate's energizing circuit consists of two conductive contacts connected in series, and the moisture-wicking layer is connected between the two conductive contacts. Figure 12 and Figure 14 As shown, a sensing unit is installed inside each support column 22 and between it and the reinforcing strip 5. The sensing unit includes a pre-crushing rod 91 fixedly connected to the inner wall of the support column 22 and multiple supplementary steel rods 92 fixedly connected to the ends of the reinforcing strip 5. The pre-crushing rod 91 is wrapped with a flexible mesh sleeve, mainly used to restrain the fragments after the pre-crushing rod 91 breaks, making them less likely to spread and reducing their impact on the movement of the reinforcing strip 5. Figures 12-13 From a top-down perspective, the pre-crushing rod 91 and the supplementary steel rod 92 are misaligned. When the electromagnetic sheet is energized and the reinforcing strips 5 separate and expand laterally under the action of magnetic attraction, the pre-crushing rod 91 is less likely to intercept multiple supplementary steel rods 92. The pre-crushing rod 91 is made of hollow brittle material and is filled with water. This allows the pre-crushing rod 91 to break quickly when the support column 22 is bent under force, and the water inside it overflows. This causes the moisture-wicking layer to absorb water, thereby making the circuit where the electromagnetic sheet is located conductive, and thus adsorbing the reinforcing strips 5 to separate quickly.

[0048] The pre-crushing rod 91 and the replacement steel rod 92 have the same diameter, and the replacement steel rod 92 is a rigid, fixed structure. The replacement steel rod 92 includes two end segments 921, a through rod 923 fixedly connected between the two end segments 921, and a micro-moving segment 922 movably sleeved outside the through rod 923. The adjacent end segments 921 and micro-moving segments 922 are in contact with each other, and the two micro-moving segments 922 are in contact with each other. The diameter of the through rod 923 is smaller than the inner diameter of the micro-moving segment 922, so that multiple micro-moving segments 922 can be offset to a certain extent under the constraint of the through rod 923. When the reinforcing strip 5 moves toward the pre-crushing rod 91, multiple replacement steel rods 92 can undergo a certain adaptive deformation when blocked by the broken pre-crushing rod 91, so as to reduce the impact of the breakage of the pre-crushing rod 91 on the movement of the reinforcing strip 5.

[0049] In this embodiment, the plate 201 and the support column 22 are detachably connected, for example by bolts. The connection between the edge of the plate 201 and the support column 22 is sealed to prevent rainwater from seeping into the support column 22. This makes it less likely for the moisture-wicking layer to get wet accidentally and less likely for the strength compensation unit to be accidentally triggered.

[0050] Compared to the first implementation, this implementation eliminates the need for data transmission, decision-making, and execution processes from the laser rangefinder 7 when deformation tends to occur. Once the electromagnetic sheet is energized due to the breakage, the two reinforcing strips 5 can be separated immediately, reducing the impact of data transmission delay on the reinforcement of the support column 22. In specific implementations, those skilled in the art can selectively configure this according to actual needs.

[0051] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
