Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, specifically an adjustable photovoltaic support. Background Technology

[0002] With the deepening of the concept of "energy integration", the construction of photovoltaic power generation systems using space resources along highways has become an important direction for technological development.

[0003] Highways, urban expressways, and ordinary national and provincial trunk roads possess abundant idle space resources, including roadside slopes, medians, interchange open spaces, tunnel entrances and exits, and the tops of sound barriers. Deploying photovoltaic power generation systems in these areas can not only effectively revitalize idle land resources along highways, but the generated electricity can also directly supply to transportation facilities such as toll stations, service areas, tunnel lighting, traffic lights, and monitoring equipment, achieving on-site production and consumption of clean energy, reducing the operating electricity costs of transportation facilities, and decreasing dependence on grid power. However, installing photovoltaic power generation systems along highways faces technical challenges that are significantly different from those of conventional ground-mounted power stations and rooftop distributed photovoltaic systems.

[0004] On the one hand, highway scenarios present a clear requirement for the adjustability of photovoltaic (PV) mounting angles. Highways typically run in long, narrow strips, and the installation orientation of PV modules is heavily constrained by the road's direction; east-west and north-south roads have significantly different sunlight reception conditions. Furthermore, the original tilt angles of installation locations such as highway slopes and roadside surfaces vary, and different road sections may have obstructions such as mountains, trees, and bridge structures, affecting the sunlight reception of PV modules. To maximize sunlight reception efficiency and increase power generation per unit area, the tilt angle of PV modules needs to be flexibly adjusted according to the road direction, the terrain conditions of the installation location, and seasonal changes.

[0005] On the other hand, highway scenarios place rigid demands on the flexible buffering performance of photovoltaic (PV) mounting systems. Continuous vehicle traffic along highways transmits periodic vibrations generated by vehicles to the PV mounting system via the ground, slopes, or sound barriers. In particular, the combined effects of impact loads from heavy trucks, bumps and vibrations caused by uneven road surfaces, and wind loads exert continuous dynamic loads on the PV modules. Prolonged exposure to such vibrations will cause the PV system's power generation efficiency to decline year by year, significantly shorten its lifespan, and increase the system's total lifecycle maintenance costs.

[0006] Therefore, current technology lacks a roadside photovoltaic (PV) support system that can simultaneously achieve both angle adjustability and vibration damping performance. Specifically, traditional adjustable-angle PV supports typically employ an angle adjustment mechanism composed of gears, lead screws, push rods, and multiple hinged nodes, resulting in a complex overall structure. Under continuous vibration conditions along highways, the moving parts and connecting nodes in this complex structure are prone to wear, jamming, and even breakage, making it difficult to guarantee the reliability of the support system in a vibration environment. More importantly, traditional adjustable-angle supports are rigid structures with a rigid connection to the PV panels. Vibrations from passing vehicles are transmitted to the support through the mounting base and then directly to the PV panels with almost no attenuation. Long-term exposure to such high-frequency micro-vibrations can lead to microcracks in the PV cells, peeling of the EVA film, and fatigue fracture of the busbar solder joints, causing a gradual decrease in the PV panel's output power and a significant reduction in its lifespan. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an adjustable photovoltaic support system, which solves the technical problems of traditional adjustable photovoltaic support systems being easily damaged due to their complex structure in the vibration environment along highways, and the rigid connection directly transmitting vibration to the photovoltaic panels, resulting in a shortened service life.

[0012] Preferably, the linear moving component includes a long shaft component.

The long shaft component is rotatably engaged with the first connecting seat, the second connecting seat, and the stabilizing bushing. A screw section is provided in the area between the first connecting seat and the second connecting seat of the long shaft component. A moving block is engaged with the screw section, and the moving block is slidably engaged with the slot frame.

The power transmission assembly and the protective shell are fixed according to the arrangement positions of the power units and the support units.

[0018] This invention provides an adjustable photovoltaic mounting bracket. It has the following advantages: 1. This invention achieves integrated flexible adjustment of photovoltaic panel angle and vibration buffering through the coordinated operation of a diagonal frame, sliding component, driving component, and steel wire rope. Specifically, the diagonal frame is rotatably mounted on top of the first support member, and the movable rod of the sliding component slides vertically under the drive of the driving component. The top of the movable rod directly pushes the diagonal frame to deflect around the rotation axis, thereby realizing continuous adjustment of the photovoltaic panel tilt angle. The angle adjustment range can reach 20° to 45°, which can fully adapt to the different needs of different road directions, different installation locations, terrain conditions, and seasonal changes in the illumination angle along highways.

[0019] 2. This invention achieves dual buffering of vehicle traffic vibrations through the elastic connection of the steel wire rope and the self-lubricating cooperation of the carbon plate components, effectively solving the technical problem of traditional rigid supports directly transmitting vibrations to photovoltaic panels, leading to a shortened service life. On one hand, the two ends of the steel wire rope are connected to the first connection point and the drive component on the inclined frame, respectively. The middle section passes around the wheel at the bottom of the movable rod and the wheel assembly at the second connection point on the inclined frame, forming a triangular stable structure. When the vibrations generated by vehicle traffic are transmitted to the support through the mounting base, the steel wire rope absorbs part of the vibration energy through its own elastic expansion and contraction deformation, attenuating the vibration amplitude transmitted to the photovoltaic panel, thus avoiding the problem of vibrations being directly transmitted to the photovoltaic panel without attenuation in traditional rigid structures. On the other hand, the carbon plate components, which are fixedly connected to the inner side of the restricting side plate, are made of carbon fiber reinforced composite material. They contain uniformly distributed lubricating components, which can form a solid lubrication transfer film at the friction interface during the relative sliding process between the carbon plate components and the inclined frame, giving the carbon plate components self-lubricating properties. This allows for smooth, long-term maintenance-free sliding without the need for additional lubricant.

[0020] 3. This invention achieves a synergistic effect of angle adjustment and structural enhancement through the adaptive length adjustment of the wire rope during the change of the tilt angle of the inclined frame. The first and second connection points of the wire rope are located on both sides of the movable rod, forming a triangular stable structure together with the wheel at the bottom of the movable rod. When the tilt angle of the inclined frame increases, the sum of the lengths of the first and second sections of the wire rope decreases, while the length of the third section of the wire rope increases, and the rate of increase of the length of the third section accelerates with the increase of the tilt angle, resulting in an increase in the tension of the wire rope as the tilt angle of the inclined frame increases. This characteristic brings two beneficial effects: First, under large tilt angles, the tension of the wire rope automatically increases, which can effectively resist the lifting effect of external loads such as wind loads on the photovoltaic panels, ensuring the stability of the photovoltaic panels in windy weather; Second, the characteristic that the tension of the wire rope increases with the increase of the tilt angle naturally forms a limiting mechanism for the maximum tilt angle of the inclined frame, avoiding the photovoltaic panel tilt angle from exceeding the safe range due to misoperation or drive component failure, thus improving the safety of the system.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0024] like Figures 1-8 As shown, this embodiment of the invention provides an adjustable photovoltaic (PV) bracket for the construction of PV power generation systems along highways, particularly suitable for the installation of solar PV modules on roadside slopes, medians, interchange areas, tunnel entrances and exits, and the tops of sound barriers along highways, urban expressways, and ordinary national and provincial trunk roads. This PV bracket allows for flexible adjustment of the tilt angle of the PV modules while effectively buffering the continuous vibrations generated by passing vehicles, protecting the PV modules from vibration damage and extending the lifespan of the PV system. The generated electricity can be directly supplied to toll stations, service areas, tunnel lighting, traffic lights, monitoring equipment, and other traffic facilities along the route, achieving on-site production and consumption of clean energy. Specifically, it includes several support units 1 arranged parallel to the highway direction. The tops of the inclined frames 102 of multiple support units 1 are all fixedly fitted with purlins 2, which are used to install PV panels.

[0025] like Figure 3As shown, the inclined frame 102 of each support unit 1 is an angle-adjustable structure; specifically, the support unit 1 includes an inclined frame 102, a first support member 101, a second support member 103, a sliding member, a driving member, and a steel wire rope 1012; the first support member 101 and the second support member 103 are both fixedly installed on the hardened ground; for example, installed on pre-cast or deeply buried concrete foundation piles. The diagonal brace 102 is rotatably mounted on the top of the first support 101, and the sliding member is mounted on the top of the second support 103. The top end of the movable rod 108 of the sliding member is used to support the diagonal brace 102, and the tilt angle of the diagonal brace 102 can be adjusted by using the top support of the movable rod 108. The driving member is used to drive the movable rod 108 of the sliding member to slide up and down. One end of the wire rope 1012 is connected to the first connection point a on the diagonal brace 102, and the other end passes around the wheel 1081 at the bottom of the movable rod 108 of the sliding member and the wheel set at the second connection point b on the diagonal brace 102 before being connected to the driving member. The driving member is used to drive the movable rod 108 of the sliding member to move in the vertical direction. The first connection point a and the second connection point b of the wire rope 1012 are located on both sides of the movable rod 108 of the sliding member.

[0026] The first support member 101 adopts a double-column support structure, which provides stable support and sufficient anti-tilting capacity. A hinge seat is fixedly connected to the top of the first support member 101, and an ear is installed below the diagonal frame 102 and near the bottom. The ear is rotatably mounted to the hinge seat via a shaft (for convenience, the axis of the shaft is referred to as the axis of rotation). The second support member 103 also adopts a double-column support structure. A crossbeam + diagonal brace structure is installed at the top to fix the guide seat 104 of the sliding member. The movable rod 108 of the sliding member is slidably engaged with the inner side of the guide seat 104. The length of the movable rod 108 is designed to be greater than the length of the guide seat 104, so that both ends of the movable rod 108 extend from the upper and lower ends of the guide seat 104 respectively. The top of the movable rod 108 of the sliding member corresponds to the bottom of the inclined rod frame 102. When the movable rod 108 slides upward, its top pushes the inclined rod frame 102, causing the inclined rod frame 102 to rotate around the rotation axis, so as to realize the angle adjustment of the inclined rod frame 102 (increasing the angle with the horizontal); conversely, when the movable rod 108 slides downward, it naturally causes the inclined rod frame 102 to fall downward, also realizing the angle adjustment (decreasing the angle with the horizontal).

[0027] Specifically, a driving component is designed to drive the movable rod 108 of the sliding component to move in the vertical direction; in this way, the tilt angle of the inclined frame 102 can be automatically / controlled by the driving component; when the tilt angle of the inclined frame 102 changes, the angle of the purlin 2 installed on the inclined frame 102 also changes, thereby adjusting the angle of the photovoltaic panel installed on the purlin 2.

[0028] To ensure that the inclined rod frame 102 can move stably with the top of the movable rod 108, a steel wire rope 1012 is also designed. A connecting seat is fixedly installed at the first connection point a of the steel wire rope 1012, and a wheel set is fixedly installed at the second connection point b of the steel wire rope 1012. One end of the steel wire rope 1012 is connected to the first connection point a on the inclined rod frame 102, and the other end passes over the rotating wheel 1081 at the bottom of the movable rod 108 of the sliding member and the wheel set at the second connection point b on the inclined rod frame 102 before being connected to the driving member. like Figure 3 As shown, the wire rope 1012 includes: a first section c3 located between the first connection point a and the pulley 1081 at the bottom of the movable rod 108; a second section c2 located between the pulley 1081 at the bottom of the movable rod 108 and the second connection point b; and a third section c1 located between the second connection point b and the driving member.

[0029] As can be seen, a triangular structure is formed between the first segment c3, the second segment c2, and the first connection point a and the second connection point b of the inclined frame 102, thereby enabling the wire rope 1012 to stably approach the movable rod 108 and ensuring the stability of the inclined frame 102 during adjustment. When facing strong winds, the strong airflow causes the inclined frame 102 to tend to rotate upwards. The design of the wire rope 1012 stabilizes the photovoltaic panel, ensuring structural strength during use.

[0030] In one embodiment, the sliding member includes a guide seat 104 and a movable rod 108. The movable rod 108 is slidably fitted on the inner side of the guide seat 104 in the vertical direction, and the top end of the movable rod 108 is connected to the inclined rod frame 102 through an adaptive interlocking member 107. The bottom of the movable rod 108 is rotatably provided with a rotating wheel 1081 and a limiting cover 1082.

[0031] It is understandable that when the movable rod 108 slides up and down, its top end is used to push the inclined rod frame 102. At this time, the top end of the inclined rod frame 102 and the bottom end of the inclined rod frame 102 form sliding and rotational motion. Based on the design of the adaptive interlocking component 107, it can adapt to the cooperation between the top end of the movable rod 108 and the inclined rod frame 102.

[0032] Specifically, the adaptive interlocking component 107 includes an integrally formed lower half 1072 and upper half 1071. The lower half 1072 is rotatably connected to the top end of the movable rod 108, allowing the adaptive interlocking component 107 to rotate as a whole relative to the movable rod 108. A fixed side plate 10711 is fixedly mounted on the top of the upper half 1071, and a limiting side plate 1073 is rotatably connected to the other side of the top of the upper half 1071. A limiting slot is formed between the limiting side plate 1073 and the fixed side plate 10711, and the diagonal frame 102 is located inside the limiting slot, thus limiting the diagonal frame 102 to the left and right. 02. To prevent longitudinal movement of the diagonal brace 102, the inner side of the side plate 1073 is fixedly connected to a carbon plate 1074 that mates with the side of the diagonal brace 102. The inner side of the carbon plate 1074 slides and fits against the working surface of the side wall of the diagonal brace 102. The carbon plate 1074 is made of carbon fiber reinforced composite material and contains uniformly distributed lubricating components. During the relative sliding process between the carbon plate 1074 and the diagonal brace 102, the lubricating components can form a solid lubrication transfer film at the friction interface, giving the carbon plate 1074 self-lubricating properties and preventing jamming.

[0033] In one embodiment, the driving component includes a slot frame 109, which is fixedly connected to the first support member 101 and the second support member 103, and a linear moving member 105 is fixedly disposed inside the slot frame 109.

[0034] like Figure 3 , Figure 4 As shown, a middle support 10101 is provided in the middle of the first support 101, and an auxiliary support frame 10301 is provided on the inner side of the second support 103. The slot frame 109 is fixedly installed on the middle support 10101 and the auxiliary support frame 10301. The slot frame 109 is in a horizontal state, and the linear moving part 105 is installed on the inner side of the slot frame 109.

[0035] The drive unit also includes a first connecting rod 1010, a short section 106, and a second connecting rod 1011. The first end of the second connecting rod 1011 is rotatably connected to the short section 106, the short section 106 is rotatably connected to the slot frame 109, the second end of the second connecting rod 1011 is rotatably connected to the bottom end of the movable rod 108, the first end of the first connecting rod 1010 is rotatably connected to the actuating end of the linear motion member 105, and the second end of the first connecting rod 1010 is rotatably connected to the middle part of the second connecting rod 1011.

[0036] It is understandable that the actuating end of the linear motion member 105 drives the first end of the first link 1010 to move. Simultaneously, the angle of the first link 1010 changes, causing the top of the first link 1010 to drive the second link 1011 to change angle. The top of the second link 1011 then drives the bottom of the movable rod 108 to move up and down. For example, when the actuating end of the linear motion member 105 drives the first end of the first link 1010 to move to the right, the second end of the first link 1010 moves upward, pushing the second link 1011 to rotate upward, causing the top of the second link 1011 to vertically push the movable rod 108 to slide upward.

[0037] One end of the wire rope 1012 is connected to the second connecting rod 1011, and a third segment c1 is formed between one end of the wire rope 1012 and the second connecting rod 1011.

[0038] It is understandable that, such as Figure 3 As shown, in the system formed by the support unit 1, when the tilt angle of the inclined frame 102 increases, the sum of the lengths of the first segment c3 and the second segment c2 decreases, while the length of the third segment c1 increases. Moreover, the rate at which the length of the third segment c1 increases with the increase of the tilt angle of the inclined frame 102 is relatively large. That is, when the tilt angle of the inclined frame 102 increases, the auxiliary stabilization system formed by the wire rope 1012 becomes more stable (the tension of the wire rope 1012 is greater), and has a maximum threshold that limits the maximum tilt angle of the inclined frame 102, ensuring the safety of the support unit 1.

[0039] Specifically, the steel wire rope 1012 adopts a 6×19 structure high-strength galvanized steel wire rope with an elastic modulus of 100 GPa~110 GPa; the nominal diameter of the steel wire rope 1012 is selected from 6 mm to 10 mm, and the breaking tensile force is not less than 20 kN; the angle adjustment range of the photovoltaic panel is 20°~45°.

[0040] In one embodiment, the linear moving member 105 includes a long shaft member. A first connecting seat 1502, a second connecting seat 1501, and a stabilizing bushing 1503 are fixedly connected to the inner side of the slot frame 109. The long shaft member is rotatably engaged with the first connecting seat 1502, the second connecting seat 1501, and the stabilizing bushing 1503. A screw section 1504 is provided in the area between the first connecting seat 1502 and the second connecting seat 1501 on the long shaft member. A moving block 1505 is engaged with the screw section 1504, and the moving block 1505 is slidably engaged with the slot frame 109. One end of the long shaft member passes through the end plate of the slot frame 109 to form a drive shaft end 1506.

[0041] It is understood that the first connecting seat 1502, the second connecting seat 1501, and the stabilizing bushing 1503 are all used for the stable rotational installation of the long shaft component; a screw section 1504 is provided in the area between the first connecting seat 1502 and the second connecting seat 1501 of the long shaft component, and a moving block 1505 is connected to the screw section 1504; the long shaft component is driven to rotate at the transmission shaft end 1506, and its screw section 1504 cooperates with the moving block 1505 to drive the moving block 1505 to slide axially, and the moving block 1505 moves in conjunction with the first end of the first connecting rod 1010.

[0042] In one embodiment, multiple support units 1 are arranged in parallel, and the driving components of the multiple support units 1 share a single power unit 3. Using a single power unit 3 to drive the transmission shaft ends 1506 of multiple support units 1 in a coordinated manner has the advantages of simple power structure and low equipment cost; moreover, the inclined rod frames 102 of multiple support units 1 should be adjusted synchronously to ensure the stability of photovoltaic panel angle adjustment. This coordinated drive structure design of a single power unit 3 is suitable for the above-mentioned operations.

[0043] In one embodiment, the power unit 3 includes a protective housing 301, a coaxial 303 is rotatably mounted inside the protective housing 301, and a rotating power member 302 is fixedly mounted at one end of the protective housing 301. The rotating power member 302 is used to drive the coaxial 303 to rotate.

[0044] Specifically, the rotational power component 302 is a geared motor, including a reducer 3022 and a drive motor 3021. The drive motor 3021 drives the reducer 3022, and after reduction and torque increase, drives the coaxial 303 to rotate.

[0045] The protective housing 301 has a sliding guide 304 inside. The sliding guide 304 has a power transmission assembly 305 in the same number as the support unit 1. The power transmission assembly 305 and the protective housing 301 are fixed according to the arrangement of the power unit 3 and the support unit 1. Generally, additional screws can be used to fix the power transmission assembly 305 and the protective housing 301. The power transmission assembly 305 is used to transmit the rotation of the coaxial 303 to the transmission shaft end 1506 of the linear moving part 105 of the sliding member.

[0046] It is understandable that the rotational power component 302 drives the coaxial 303 to rotate, the coaxial 303 synchronously drives multiple power transmission components 305 to move, and the power transmission components 305 drive their corresponding transmission shaft ends 1506 to rotate.

[0047] In one embodiment, the power transmission assembly 305 includes an L-shaped plate 3051. The bottom of the L-shaped plate 3051 is slidably engaged with the sliding guide 304, thereby allowing the overall position of the L-shaped plate 3051 to be adjusted. When it is determined to correspond with the drive shaft end 1506, it is locked with screws. The L-shaped plate 3051 has an integrally designed horizontal plate and a vertical plate. A first bevel gear 3052 is rotatably connected to the vertical plate of the L-shaped plate 3051. The first bevel gear 3052 is fixedly connected to the drive shaft end 1506. A second vertical plate 3053 is fixedly connected to the inner side of the L-shaped plate 3051. The second vertical plate 3053 is rotatably connected to a second bevel gear 3054. The second bevel gear 3054 is in a transmission engagement with the first bevel gear 3052, and the second bevel gear 3054 is in a sliding engagement with a coaxial 303. A key structure is provided between the second bevel gear 3054 and the coaxial 303. For example, the cross-section of the coaxial 303 is designed to be non-circular, such as a circle with a missing corner. The inner hole of the second bevel gear 3054 corresponds to the cross-section of the coaxial 303, thereby enabling the sliding of the second bevel gear 3054 and the coaxial 303. The coaxial 303 can always drive the second bevel gear 3054 to rotate.

[0048] It is understandable that the coaxial 303 drives the second bevel gear 3054 to rotate, the second bevel gear 3054 drives the first bevel gear 3052 to rotate, and then the first bevel gear 3052 drives the transmission shaft end 1506 to rotate.
