Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module device technology, and in particular to a valley-regulating photovoltaic power generation device. Background Technology

[0002] Solar energy, as a crucial component of renewable energy, is primarily utilized through photovoltaic (PV) power generation. Existing PV power plants mostly employ fixed mounting systems to house PV modules. However, due to the lack of adjustment capabilities in these fixed systems, the daily power generation curve of the PV system exhibits significant peaks and troughs, resulting in uneven power generation distribution across different time periods. Under time-of-use pricing policies, the midday period, characterized by the strongest sunlight and highest power output, typically corresponds to lower electricity prices, preventing PV power plants from fully realizing their potential revenue and impacting their economic efficiency and sustainable operation. Therefore, developing a PV power generation system with a rational structure that effectively extends the PV power generation time period while simultaneously increasing revenue during off-peak electricity price periods has significant practical importance and application value.

[0003] Existing technology has developed tracking photovoltaic (PV) mounting systems, which are systems capable of automatically adjusting the angle of sunlight on PV equipment based on the sun's position and illumination conditions. The constant variation of sunlight throughout the year and day allows the solar panels to follow the direction of the sunlight, thus facilitating better light absorption and improving photoelectric conversion efficiency. Compared to fixed installations, tracking mounting systems significantly improve power generation efficiency, but also incur higher maintenance costs. Common tracking angle ranges for single-axis tracking mounting systems are typically ±45° or ±60°, while some dual-axis tracking mounting systems can even achieve omnidirectional angle adaptation, maximizing sunlight tracking.

[0004] However, tracking photovoltaic (PV) mounting systems have the following drawbacks: First, they have high investment costs. Their complex mechanical structures and the cost of drive units (motors, sensors, etc.) and support materials are far higher than those of fixed mounting systems. Maintenance costs are also high, as moving parts are prone to wear and require regular maintenance (such as lubrication and motor replacement), increasing long-term operating costs, especially in harsh environments such as sandstorms and salt spray. Second, tracking PV systems have a high failure rate. Precision mechanical and electronic components (such as light sensors and control systems) may fail due to extreme weather (hail, strong winds) or long-term operation, leading to system shutdown. Third, they require a large footprint, with significant spacing between mounting structures, resulting in low land utilization. Fourth, they have poor environmental adaptability. Tracking PV systems have a large windward area, requiring additional reinforcement in areas with high wind speeds. Snow accumulation in high-latitude regions may hinder rotation, and sandstorms in arid regions will accelerate component wear. Utility Model Content

While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0025] like Figures 1 to 3As shown, an embodiment of this utility model proposes a valley-regulating photovoltaic power generation device, including: multiple prefabricated piles 1; Fixed supports 20 located on multiple precast piles 1; The tilted photovoltaic module 2 is located on the upper part of the fixed bracket 20 and is arranged at an angle; Vertical photovoltaic modules 3 are located at the lower part of the fixed support 20 and arranged vertically; the vertically arranged vertical photovoltaic modules 3 and the inclined photovoltaic modules 2 are arranged in combination to broaden the sunshine utilization period, improve the peak and valley characteristics of the power generation curve, and increase the power generation during the off-peak electricity price period. The lower part of the fixed bracket 20 is provided with a steel strand cable locking mechanism fixedly connected to the fixed bracket 20, and the vertical photovoltaic module 3 is fixed on the steel strand cable locking mechanism. By using flexible steel strand cables, the concentrated load of the vertical photovoltaic module 3 can be effectively distributed, improving the safety and stability of the overall system structure.

[0026] This off-peak photovoltaic (PV) power generation device extends the power generation period of the PV system through a double-layer layout of tilted PV modules 2 and vertically arranged PV modules 3 on the front side. This effectively increases power generation during early morning, late evening, and off-peak hours, improving the problem of troughs in the daily power generation curve of traditional fixed-support PV systems. The vertically arranged PV modules 3, while ensuring safety and structural stability, increase the output of the PV system during off-peak hours, enhancing the economic benefits of the PV power station under time-of-use pricing conditions.

[0027] For example, the fixing bracket 20 includes: Multiple vertical support components are fixedly connected to multiple precast piles 1 in a one-to-one correspondence, and the upper end of each vertical support component is inclined. Multiple first horizontal purlins 4 are arranged in parallel and span across the upper ends of multiple vertical support components.

The first steel strand cable zipper 5 and the second steel strand cable zipper 6 are arranged parallel to each other vertically. The vertical photovoltaic module 3 is fixed on the first steel strand cable zipper 5 and the second steel strand cable zipper 6. The vertical photovoltaic modules 3 arranged horizontally on the front side of the fixing bracket 20 are fixed by two parallel steel strand cable zippers. By using flexible steel strand cables, the concentrated load of the vertical photovoltaic modules can be effectively distributed, improving the safety and stability of the overall system structure.

[0029] For example, the fixing bracket 20 further includes: The second transverse purlin 7 is located above the steel strand zipper mechanism and spans across the middle of the plurality of vertical support components; Multiple damping components 8 are provided on the second transverse purlin 7, such as... Figure 4 As shown, the damping component 8 includes a purlin clip 801, a spring 802, and a first fastening block component 803. One end of the spring 802 is connected to the purlin clip 801, and the other end is connected to the first fastening block component 803. The purlin clip 801 is fixedly connected to the second transverse purlin 7, and the first fastening block component 803 is fixedly connected to the upper edge of the vertical photovoltaic module 3. By fixing the upper edge of the vertical photovoltaic module 3 with the damping component 8, the load force of the vertical photovoltaic module 3 on the steel strand cable mechanism can be reduced, and it can also withstand stronger external environmental loads, ensuring the long-term stable operation of the device.

[0030] For example, the purlin clip 801 is fixed to the second transverse purlin 7 by screws.

[0031] For example, the vertical support component includes: The first inclined purlin 9, the first vertical purlin 10, the second vertical purlin 11, and the second inclined purlin 1 are located on the same plane; The upper height of the first inclined purlin 9, the first vertical purlin 10, the second vertical purlin 11, and the second inclined purlin 12 gradually decreases to form an inclined angle; The lower ends of the first inclined purlin 9, the first vertical purlin 10, and the second inclined purlin 12 are all higher than the lower end of the precast pile 1, and the lower end of the second vertical purlin 11 is flush with the lower end of the precast pile 1. The first inclined purlin 9, the first vertical purlin 10, the second vertical purlin 11, and the second inclined purlin 12 are fixed to the precast pile 1 by clamps 13; the clamps 13 are arranged in pairs, with the first vertical purlin 10 and the second vertical purlin 11 respectively arranged on both sides of the precast pile 1; the first inclined purlin 9 is arranged adjacent to the first vertical purlin 10 and has a certain inclination angle; the second inclined purlin 12 is arranged adjacent to the second vertical purlin 11 and has a certain inclination angle. Multiple first transverse purlins 4 are fixedly connected to the first inclined purlin 9, the first vertical purlin 10, the second vertical purlin 11, and the second inclined purlin 12 via supporting purlins 21; The second horizontal purlin 7 is fixedly connected to the second vertical purlin 11.

[0032] In order to enhance the stability of the fixed bracket 20, the vertical support assembly further comprises a cross arm 14. Said cross arm 14 is fixedly connected to the first inclined purlin 9, the first vertical purlin 10, the second vertical purlin 11 and the second inclined purlin 12 respectively, and said cross arm 14 is pressed against the upper end of the precast pile 1.

[0033] Exemplarily, the inclined photovoltaic module 2 is fixed on said first transverse purlin 4 via the second fastening pressure block members 15, and a plurality of second fastening pressure block members 15 are arranged on said first transverse purlin 4.

[0034] As shown in Figure 5 , said second fastening pressure block member 15 comprises an inverted "Ji"-shaped first upper support 1501 and a regular "Ji"-shaped first lower support 1502 located below said first upper support 1501; said second fastening pressure block member 15 is fixedly connected to said first transverse purlin 4, one inclined photovoltaic module 2 is fixedly fixed between two adjacent second fastening pressure block members 15, and two opposite edge margins of said inclined photovoltaic module 2 are clamped between the inverted "Ji"-shaped hook of the first upper support 1501 and the regular "Ji"-shaped hook of the first lower support 1502 respectively. This structure not only avoids collision between two adjacent inclined photovoltaic modules 2, but also ensures the stability of the photovoltaic modules under the action of external environments such as wind load.

[0035] It should be noted that the structure of the first fastening pressure block member 803 in the damping member 8 is similar to that of the second fastening pressure block member 15, and in the damping member 8, one end in the vertical direction of the structure abutting against the second fastening pressure block member 15 is fixedly connected to said spring 802. The side edge of the upper end of the vertical photovoltaic module 3 is clamped between the inverted "Ji"-shaped hook and the regular "Ji"-shaped hook, so as to realize the fixation of the upper end.

[0036] Exemplarily, the vertical photovoltaic module 3 is fixed on said first steel strand cable member 5 and second steel strand cable member 6 via the third fastening pressure block members 16, and a plurality of third fastening pressure block members 16 are arranged on said first steel strand cable member 5 and said second steel strand cable member 6 respectively; As shown in Figure 6As shown, the third fastening pressure block member 16 comprises an inverted "Ω"-shaped second upper support 1601, an upright "Ω"-shaped second lower support 1602 located below the second upper support 1601, and the semicircular pressure plate 1603 located below the second lower support 1602; the first steel strand cable member 5 and the second steel strand cable member 6 respectively pass through the semicircular pressure plate 1603, one vertical photovoltaic module 3 is fixed between two adjacent third fastening pressure block members 16, and two opposite side edges of the vertical photovoltaic module 3 are respectively clamped between the inverted "Ω" hooks of the second upper support 1601 and the upright "Ω" hooks of the second lower support 1602. The second upper support 1601 and the second lower support 1602 fix multiple rows of vertical photovoltaic modules 3 together, and the semicircular pressure plate 1603 firmly binds the vertical photovoltaic modules 3 to the steel strand cable mechanism. Meanwhile, in combination with the damping member 11 connected to the upper edge of the photovoltaic module, the stability of the vertical photovoltaic modules 3 is further improved, concentrated loads in the device are reduced, and the wind resistance of the system is improved.

[0037] It should be noted that when fixing the vertical photovoltaic modules 3 on both sides of the fixing device, since only the vertical photovoltaic module 3 on one side needs to be fixed, it is possible to adopt Figure 7 the edge fastening pressure block member 22 shown, the edge fastening pressure block member 22 comprises a half inverted "Ω"-shaped upper support 2201, a half upright "Ω"-shaped lower support 2202 located below the upper support 2201, and the semicircular pressure plate 2203 located below the lower support 2202.

[0038] Exemplarily, the first inclined purlin 9, the first vertical purlin 10, the second vertical purlin 11, and the second inclined purlin 12 are fixed on the precast pile 1 by a plurality of hoops 13; Both ends of the first steel strand cable member 5 are respectively fixed on the bases 17 of the precast piles 1 on both sides, the middle part of the first steel strand cable member 5 passes through the gap of the uppermost hoop 1301, and the first steel strand cable member 5 is fixed on the second vertical purlin 11 by using a fixing pressure plate 18; Both ends of the second steel strand cable member 6 are respectively fixed on the bases 17 of the precast piles 1 on both sides, the middle part of the second steel strand cable member 6 passes through the gap of the lowermost hoop 1302, and the second steel strand cable member 6 is fixed on the second vertical purlin 11 by using a fixing pressure plate 18. Through this flexible steel strand cable fixing method, an integral stress system is formed, the load of the vertical photovoltaic modules 3 is evenly dispersed, the damage to the fixing support 20 caused by concentrated stress is avoided, and the safety and service life of the overall structure are improved.

[0039] As Figure 8 shown, the fixing pressure plate 18 is semicircular.

[0040] For example, the first transverse purlin 4 is fixedly connected to the supporting purlin 21 via a purlin bracket 19.

[0041] Through the above structural design, this invention not only improves the power generation per unit area but also optimizes the daily power generation curve, enhances the system's stability and safety under external environmental influences, and possesses good scalability and adaptability. The vertical and horizontal double-layer arrangement of photovoltaic modules can be adjusted according to actual site conditions and economic needs, providing a practical and feasible efficiency-enhancing technology solution for photovoltaic power plants.

[0042] Compared with existing technologies, this invention significantly improves the installed capacity and power generation efficiency of photovoltaic devices under limited land conditions, making full use of the space beneath traditional fixed supports. Simultaneously, through the combined arrangement of inclined and vertical components, it broadens the effective time period of photovoltaic power generation, improves the peak-valley characteristics of the daily power generation curve, shortens the trough duration, and effectively increases power generation revenue during off-peak electricity price periods, thereby significantly improving the overall economic benefits of photovoltaic power plants.
