Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment technology, and in particular to a photovoltaic bracket and photovoltaic equipment. Background Technology

[0002] Related technologies indicate that, against the backdrop of the rapid development of the global photovoltaic market, photovoltaic mounting systems, as an important component of solar photovoltaic power generation systems, play a crucial role in supporting and fixing photovoltaic modules. They not only need to possess strong mechanical properties such as resistance to wind pressure, snow pressure, earthquakes, and corrosion to ensure normal operation in various harsh environments, but are also constantly evolving to adapt to the industry's needs for cost reduction and efficiency improvement.

[0003] Traditional fixed photovoltaic (PV) mounting systems, due to their fixed location, cannot be adjusted according to changes in the sun's position, which significantly limits the efficiency of PV power generation systems. Because the angle of sunlight incidence varies with time and season, fixed-installation PV modules cannot always receive solar radiation at the optimal angle, resulting in low energy conversion efficiency. When sunlight shines from the side for extended periods, it can cause localized overheating or other forms of stress on the PV modules, potentially adversely affecting their performance parameters and even damaging them over time, shortening their lifespan. In such cases, not only is power generation affected, but maintenance costs and the need for module replacement also increase. Summary of the Invention

[0053] Related technologies indicate that, against the backdrop of the rapid development of the global photovoltaic market, photovoltaic mounting systems, as an important component of solar photovoltaic power generation systems, play a crucial role in supporting and fixing photovoltaic modules. They not only need to possess strong mechanical properties such as resistance to wind pressure, snow pressure, earthquakes, and corrosion to ensure normal operation in various harsh environments, but are also constantly evolving to adapt to the industry's needs for cost reduction and efficiency improvement.

[0054] Traditional fixed photovoltaic (PV) mounting systems, due to their fixed location, cannot adjust to changes in the sun's position, which significantly limits the efficiency of PV power generation systems. Because the angle of sunlight incidence varies with time and season, fixed-installation PV modules cannot always receive solar radiation at the optimal angle, resulting in low energy conversion efficiency. When sunlight shines from the side for extended periods, it can cause localized overheating or other forms of stress on the PV modules, potentially adversely affecting their performance parameters and even damaging them over time, shortening their lifespan. This not only impacts power generation but also increases maintenance costs and the need for module replacement. Therefore, designing a PV mounting system that can adjust its deflection angle according to the angle of sunlight has become an urgent problem to solve.

[0055] Based on the above considerations, in order to improve photovoltaic power generation efficiency and extend service life, the applicant has conducted in-depth research and designed a photovoltaic support system. The photovoltaic support system according to the first aspect of this application is described below with reference to the figures.

[0056] like Figures 1-10 As shown, Figure 1 A schematic diagram of a photovoltaic support provided in an embodiment of this application; Figure 2 for Figure 1An exploded view of the photovoltaic support structure shown in the image; Figure 3 for Figure 1 The exploded view of the photovoltaic support structure shown shows that it is equipped with photovoltaic panels; Figure 4 for Figure 1 A schematic diagram of the photovoltaic bracket's support structure, first adjustment component, and first deflection structure shown in the diagram; Figure 5 for Figure 4 A schematic diagram of the adjustment seat of the first adjustment component shown; Figure 6 for Figure 1 A schematic diagram of the space frame structure shown; Figure 7 for Figure 1 A schematic diagram of the connecting components shown; Figure 8 This is a schematic diagram of the support structure according to another embodiment of this application; Figure 9 for Figure 2 A schematic diagram of the first connector shown; Figure 10 for Figure 3 A schematic diagram of the support rod shown.

[0057] A photovoltaic bracket 100 according to a first aspect embodiment of this application includes: a support structure 1, a deflection structure, a grid structure 4, and a first adjustment component 5.

[0058] Specifically, the relative deflection angle between the deflection structure and the support structure 1 is adjustable. The grid structure 4 is installed on the deflection structure and is used to install the photovoltaic panel 200. Changing the relative deflection angle between the deflection structure and the support structure 1 causes the grid structure 4 to deflect, thereby changing the installation angle of the photovoltaic panel 200. The first adjustment component 5 is connected between the support structure 1 and the deflection structure to adjust the relative deflection angle between the deflection structure and the support structure 1. The first adjustment component 5 includes multiple gears, which can be switched between each other.

[0059] Understandably, the support structure 1 serves as the base of the entire photovoltaic bracket 100, providing stable support for it. The support structure 1 is fixed to the ground or other stable foundation structure, ensuring the stability and safety of the entire photovoltaic bracket 100. The deflection structure is connected to the support structure 1, and its deflection angle relative to the support structure 1 is adjustable. This allows the angle of the photovoltaic panel 200 to be adjusted according to changes in the sun's position, ensuring that the photovoltaic panel 200 always receives solar radiation at the optimal angle, thus improving its energy conversion efficiency. The grid structure 4 is installed on the deflection structure to support the photovoltaic panel 200. As the angle of the deflection structure changes, the grid structure 4 adjusts its angle accordingly, thereby changing the orientation and tilt angle of the photovoltaic panel 200, allowing it to face the sunlight at the optimal angle.

[0060] Furthermore, the first adjustment component 5 is connected between the support structure 1 and the deflection structure. The first adjustment component 5 is used to adjust the relative deflection angle between the support structure 1 and the deflection structure. The first adjustment component 5 has multiple gears, each gear corresponding to a different angle setting, which is used to switch between these gears according to specific weather conditions, seasons and time of day, so as to dynamically adjust the optimal angle of the photovoltaic panel 200.

[0061] Here, the solar altitude and azimuth angles vary depending on the season and time of day. Setting multiple settings improves the adaptability and flexibility of the photovoltaic bracket 100. By adjusting the angle of the photovoltaic panel 200, it can be made as perpendicular as possible to the direction of sunlight, thereby improving energy conversion efficiency. It is also easy to operate, and even personnel without professional technical background can easily and accurately adjust the angle of the photovoltaic panel 200, simplifying maintenance work.

[0062] According to the embodiments of this application, the photovoltaic support 100 is equipped with a first adjustment component 5 having multiple gears to adjust the angle of the deflection structure. The grid structure 4 adjusts its angle accordingly, thereby changing the orientation and tilt angle of the photovoltaic panel 200. This allows the photovoltaic panel 200 to face the sunlight at the optimal angle, improving photovoltaic power generation efficiency, extending the service life of the photovoltaic support 100, and making the photovoltaic support 100 easy to operate.

[0063] In any embodiment of this application, the deflection structure includes: a first deflection structure 2 and a second deflection structure 3. The first deflection structure 2 is rotatably connected to the support structure 1 about a first rotating axis. A first adjusting component 5 is connected between the support structure 1 and the first deflection structure 2. The second deflection structure 3 is rotatably connected to the first deflection structure 2 about a second rotating axis. The extending directions of the first rotating axis and the second rotating axis are different. (Refer to...) Figure 1 As shown, the first rotating shaft extends in the north-south direction and the second rotating shaft extends in the east-west direction. This allows the grid structure 4 to be angled in two different axial directions (i.e., the north-south direction and the east-west direction), which improves the tracking accuracy of the photovoltaic panel 200 and the energy collection efficiency. The first adjustment component 5 is used to adjust the relative deflection angle between the first deflection structure 2 and the support structure 1 in the north-south direction.

[0064] It should be noted that in the photovoltaic support 100 of this application embodiment, when the first deflection structure 2 rotates relative to the support structure 1 around the first axis, it can drive the grid structure 4 to deflect along the first direction X1 or the second direction X2; when the second deflection structure 3 rotates relative to the first deflection structure 2 around the second axis, it can drive the grid structure 4 to deflect along the third direction Y1 or the fourth direction Y2; so as to change the installation angle of the photovoltaic panel 200.

[0065] In any embodiment of this application, the first adjusting component 5 includes: an adjusting seat 51 and an adjusting rod 52. The adjusting seat 51 is disposed on the support structure 1 and has a plurality of adjusting grooves 511 arranged sequentially in the vertical direction. Each adjusting groove 511 corresponds to a gear position. One end of the adjusting rod 52 is rotatably connected to the first deflection structure 2, and the other end of the adjusting rod 52 extends into the adjusting groove 511 and abuts against the inner wall of the adjusting groove 511. Figure 4 As shown, the adjusting rod 52 extends obliquely towards the support structure 1 in a downward direction. The upper end of the adjusting rod 52 is rotatably connected to the first deflection structure 2, and the lower end of the adjusting rod 52 extends into one of the multiple adjusting slots 511 and abuts against the inner wall of the adjusting slot 511. In this way, each adjusting slot 511 represents a different setting or angle. By selecting different adjusting slots 511, the user can adjust the tilt angle of the photovoltaic panel 200 to adapt to different lighting conditions and seasonal changes.

[0066] Further as Figure 5 As shown, the adjustment slot 511 has 10 positions, arranged vertically. Each position allows for an adjustment angle of 4-5°, suitable for latitudes in most regions throughout the four seasons. Data testing has been conducted to determine the required adjustment positions for different latitudes and seasons, facilitating easy adjustment. Users can adjust the angle according to the solar altitude in different seasons as shown in the table below to fully utilize the photovoltaic module's power generation. (The adjustment positions shown in the table are the settings.)

[0067]

[0068] For example, the adjusting seat 51 has a height of 200-500mm, a length of 30-80mm, a width of 10-50mm, and a thickness of 1.5-4mm. The adjusting rod 52 is a square tube with a length of 20-25mm, a width of 20-25mm, a height of 100-500mm, and a thickness of 1.5-3mm. At both ends of the adjusting rod 52 are two through holes: one with a diameter of 8-10mm and the other with a diameter of 5-7mm. The 5-7mm through hole supports the upper first deflection structure 2, and the 7-10mm through hole connects to the slider.

[0069] Furthermore, the photovoltaic support 100 also includes a second adjustment component 6, which is connected between the first deflection structure 2 and the grid structure 4 to adjust the relative deflection angle between the second deflection structure 3 and the support structure 1. Thus, the second adjustment component 6 is used to adjust the relative deflection angle between the second deflection structure 3 and the support structure 1, and to adjust the angle of the photovoltaic panel 200 according to specific weather conditions, seasons, and time of day, so as to dynamically adjust the optimal angle of the photovoltaic panel 200.

[0070] In any embodiment of this application, each adjustment slot 511 extends in an upward direction away from the support structure 1. This not only improves the flexibility and adaptability of the photovoltaic bracket 100, but also enhances its stability and reliability. Under its own weight, the other end of the adjustment rod 52 can be stably positioned within the adjustment slot 511, preventing it from detaching and reducing the failure rate of the photovoltaic bracket 100, thereby lowering maintenance costs.

[0071] In any embodiment of this application, each adjusting groove 511 has a fixed part and a sliding part. The fixed part is located on the side of the sliding part closer to the support structure 1. The other end of the adjusting rod 52 is provided with a slider, which can slide within the sliding part and abuts against the peripheral wall of the fixed part. In this way, the sliding part plays a guiding role, enabling the other end of the slider to enter the corresponding adjusting groove 511 stably and accurately. The slider abuts against the peripheral wall of the fixed part, improving the stability and reliability of the first adjusting assembly 5 and preventing the slider from detaching from the adjusting groove 511.

[0072] In any embodiment of this application, the adjusting seat 51 has a through groove 512 extending vertically, and each adjusting groove 511 communicates with the through groove 512, allowing the slider to slide within the through groove 512. It is understood that when the angle of the photovoltaic panel 200 needs to be adjusted, the operator can manually or otherwise move the slider to slide within the through groove 512. Since the opening of each adjusting groove 511 communicates with the through groove 512, the slider can easily enter any adjusting groove 511 from the through groove 512, thereby completing the deflection angle adjustment. This improves the adjustability and convenience of the photovoltaic support 100 system, enabling users to more easily and accurately adjust the angle of the photovoltaic panel 200, thereby optimizing solar energy collection efficiency.

[0073] Here, a locking element is also provided between the slider and the adjustment groove 511. The locking element is used to lock the position of the slider and the adjustment groove 511 to prevent the slider from coming out of the adjustment groove 511.

[0074] In any embodiment of this application, the bottom wall of the first deflection structure 2 is provided with a rotating seat 21, and one end of the adjusting rod 52 is connected to the rotating seat 21 so that the adjusting rod 52 can rotate relative to the rotating seat 21. Thus, the first deflection structure 2 and the adjusting rod 52 are rotatably connected through the rotating seat 21, which improves the flexibility and adjustability of the photovoltaic bracket 100.

[0075] In any embodiment of this application, the support structure 1 includes: a base 11 and a support body 12, as shown in the figure. Figure 4As shown, the lower end of the support body 12 is connected to the base 11, and the upper end of the support body 12 forms two spaced-apart support walls 121. Each support wall 121 has a first rotating hole, and the first deflection structure 2 has a rotating hole. A bushing is provided in the rotating hole. The support body 12 and the first deflection structure 2 are rotatably connected by a first rotating shaft passing through the first rotating hole and rotating hole. Thus, the first deflection structure 2 can rotate relative to the support body 12 in a first direction X1 or a second direction X2 around the first rotating shaft.

[0076] For example, the main support 12 is made of square iron tubing with a length of 40-100mm, a width of 40-100mm, a thickness of 1-4mm, and a height of 1000-1800mm. The base 11 has a length of 100-400mm, a width of 100-400mm, and a thickness of 3-8mm. The base 11 has eight holes with a diameter of 8-18mm. All four corners of the base 11 are rounded to facilitate transportation and prevent damage to the packaging. Eight triangular ribs 13, each 140-150mm high, 60-70mm wide, and 3-8mm thick, are welded between the base 11 and the main support 12 to reinforce the connection between the base 11 and the main support 12, as well as the overall stability and wind resistance. The width between the two support walls 121 is 25-80mm, and the height of the support walls 121 is 70-150mm. A bushing is installed inside the first rotating hole.

[0077] In any embodiment of this application, in order to ensure the overall structural strength and stability of the support body 12, the support body 12 is an integrally formed structure, which makes the support body 12 have higher overall strength and rigidity, and can better resist the influence of the external environment, such as strong winds and snow accumulation.

[0078] In any embodiment of this application, in order to facilitate the production and transportation of the support body 12 and reduce the transportation cost of the support body 12, the support body 12 includes a first support rod 122 and a second support rod 123, such as... Figure 8 As shown, the first support rod 122 is connected to the upper end of the second support rod 123. The lower end of the first support rod 122 has a first connecting part 1221, and the upper end of the second support rod 123 has a second connecting part 1231. The first support rod 122 and the second support rod 123 are connected by the first connecting part 1221 and the second connecting part 1231, which allows the support body 12 to be flexibly installed and transported. At the same time, the height of the support body 12 can be adjusted according to different usage environment requirements. Furthermore, it is easier to replace the first support rod 122 or the second support rod 123 when it is damaged, thus reducing the maintenance cost of the photovoltaic bracket 100.

[0079] For example, the first support rod 122 and the second support rod 123 are both round tubes with a thickness of 2-5mm and an outer diameter of 50-120mm. The lengths of the first support rod 122 and the second support rod 123 are both 500-900mm. The lengths of the first connecting part 1221 and / or the second connecting part 1231 are 50-100mm. A cap 14 with a thickness of 5-12mm is provided at the end of the first support rod 122 away from the second support rod 123. A U-shaped sheet metal with a thickness of 5-12mm, an inner diameter of 30-70mm, and a height of 60-140mm is welded on the cap 14. The first rotating hole is formed on the U-shaped sheet metal for connecting with the first deflection structure 2.

[0080] Here, the first support rod 122 and the second support rod 123 can be connected by a welded flange, a threaded connection, or other methods. As shown in the figure, a first hole is formed on the first connecting part 1221, and a second hole is formed on the second connecting part 1231. The first support rod 122 and the second support rod 123 are connected by fasteners that pass through the first hole and the second hole.

[0081] In any embodiment of this application, the first deflection structure 2 is connected to a support rod 22, and the second adjustment assembly 6 includes a telescopic rod 61 and a driving member 62. One end of the telescopic rod 61 is connected to the driving member 62, and the other end of the telescopic rod 61 is connected to the space frame structure 4. The driving member 62 is mounted on the support rod 22 and is throttle-connected to the telescopic rod 61 to adjust the length of the telescopic rod 61. Figure 10 As shown, a reinforcing block 221 is provided at the lower end of the support rod 22. It can be understood that the second adjusting component 6 drives the moving part of the telescopic rod 61 to move relative to the fixed part of the telescopic rod 61, so that the grid structure 4 rotates about the second rotating axis relative to the first deflection structure 2 in the third direction Y1 and the fourth direction Y2. The reinforcing block 221 increases the structural strength of the support rod 22, prevents the support rod 22 from tearing, and improves the stability and reliability of the photovoltaic bracket 100.

[0082] For example, the fixed voltage of the drive unit 62 is 12 / 24V, the thrust of the telescopic rod 61 is 1000-2500N, the speed is 4-10mm / s, and the stroke is 150-400mm.

[0083] In other embodiments, the second adjustment component 6 includes a lead screw and a drive member 62. The lead screw is threadedly connected to the drive member 62. The upper end of the lead screw is rotatably connected to the space frame structure 4. The drive motor drives the lead screw to rotate to adjust the feed amount of the lead screw, thereby adjusting the extension length of the lead screw to adjust the relative deflection angle between the second deflection structure 3 and the support structure 1.

[0084] In any embodiment of this application, the grid structure 4 includes: a first rod 41, at least two spaced-apart second rods 42, and a first connector 43. The middle part of the first rod 41 is connected to the second deflection structure 3, and at least one second rod 42 is connected to each end of the first rod 41. The extension direction of the second rod 42 is different from that of the first rod 41. The first rod 41 and the second rod 42 are connected by the first connector 43. Two adjacent and spaced-apart first rods 41 and / or two adjacent and spaced-apart second rods 42 are used to support a photovoltaic panel 200. For example, the photovoltaic panel 200 can be laid in the middle of an "H"-shaped structure formed by the first rod 41 and two adjacent and spaced-apart second rods 42, without limitation.

[0085] For example, space frame structure 4 uses C-shaped square iron tubing, connected by fasteners with a diameter of 8-10mm and a length of 70-120mm. (Refer to...) Figure 2 and Figure 9 As shown, the first connector 43 includes a U-shaped fastener 431 and a fastening plate 432. Both ends of the U-shaped fastener 431 pass through the first rod 41, the second rod 42, and the fastening plate 432. Both ends of the U-shaped fastener 431 are threadedly connected to a nut.

[0086] In any embodiment of this application, the first deflection structure 2 has a first mounting groove, a first connecting seat 23 is provided in the first mounting groove, and a first connecting hole is formed on the first connecting seat 23. The second deflection structure 3 has a second mounting groove, a second connecting seat 31 is provided in the second mounting groove, and a second connecting hole is formed on the second connecting seat 31. The first deflection structure 2 and the second deflection structure 3 are rotatably connected relative to each other by a second rotating shaft extending into the first connecting hole and the second connecting hole. This enhances the connection strength between the first deflection structure 2 and the second deflection structure 3, preventing the first deflection structure 2 and the second deflection structure 3 from detaching.

[0087] For example, the first deflection structure 2 uses a square iron tube with a length of 700-1100mm, a width of 20-40mm, a height of 40-80mm, and a thickness of 1-3mm. Four 6-10mm through holes are formed on one end of the first deflection structure 2, and four bushings of corresponding sizes are welded into the through holes for connection with the support rod 22. Four first connecting seats 23 with a length of 40-60mm, a width of 25-40mm, and a thickness of 3-8mm are also provided on the top of the first deflection structure 2. The first connecting seats 23 have first connecting holes with a diameter of 8-14mm. The first rotating shaft is a fastener of φ8 / 16 or M6 / M14.

[0088] For example, the second deflection structure 3 uses a square iron tube with a length of 700-1100mm, a width of 20-40mm, a height of 40-80mm, and a thickness of 1-3mm. Both ends of the second deflection structure 3 have four 6-10mm through holes, and four bushings of corresponding sizes are welded into the through holes for connection with the support rod 22. The second deflection structure 3 also has four second connecting seats 31 with a length of 20-80mm, a width of 20-60mm, and a thickness of 2-8mm. The second connecting seats 31 have a first connecting hole with a diameter of 8-14mm. The first rotating shaft is a fastener with a diameter of φ8 / 14 and a length of 35-45mm.

[0089] Furthermore, the support rod 22 is made of iron square tube with a length of 30-80mm, a width of 20-60mm, a height of 300-800mm, and a thickness of 1-3mm. Both the first deflection structure 2 and the support rod 22 have four 6-10mm through holes, and bushings are welded into the through holes. The first deflection structure 2 and the support rod 22 are connected by M6-M10 fasteners.

[0090] In any embodiment of this application, the photovoltaic support 100 further includes a connecting component 7 for connecting the photovoltaic panel 200 and the second rod 42. The connecting component 7 includes a connecting arm 71 and a top plate 72. The connecting arm 71 has an anti-slip groove 711 formed thereon. At least a portion of the frame of the photovoltaic panel 200 extends into the anti-slip groove 711. The top plate 72 is located on the side of the second rod 42 opposite to the photovoltaic panel 200. The top plate 72 abuts against the first rod 41 by fasteners to connect the photovoltaic panel 200 to the grid structure 4. This achieves stable installation of the photovoltaic panel 200, simplifies the installation and maintenance process, improves the reliability and safety of the overall system, and ensures that the photovoltaic panel 200 can maintain optimal working condition even in harsh environments, maximizing energy harvesting efficiency.

[0091] Here, the frame of the photovoltaic panel 200 is a C-shaped steel with a width of 41mm, a height of 21-25mm, a thickness of 1.5-1.8mm, and a length of 800-1600mm, and the thickness of the connecting arm 71 is 1.8-2.5mm.

[0092] In any embodiment of this application, the grid structure 4 includes at least two grid structures 4, which are arranged adjacent to each other in the extension direction of the first deflection structure 2, and are connected by a second connector 44 and a connecting pressure block 45. This increases the area of ​​the photovoltaic panels 200 on the photovoltaic support 100, thereby enabling the acquisition of more solar energy and its conversion into electrical energy, enhancing the scalability of the photovoltaic support 100, and optimizing space utilization.

[0093] For example, the second connector 44 is U-shaped and uses steel with a thickness of 1.8-2.5mm and a length of 19-29mm. The 1.8-2.5mm thickness ensures the strength of the joint, while the 19-29mm length expands the stress points at the joint, resulting in higher strength. The length also allows for the sequential arrangement of 4-6 fasteners. Combined with the 3-6mm thick connecting block 45, the joint's firmness is ensured. The fasteners have a diameter of 8-10mm and a length of 20-30mm, and are paired with stainless steel flat washers of the corresponding diameter. Alternatively, other materials can be used to prevent rust during outdoor use.

[0094] In any embodiment of this application, the photovoltaic support 100 further includes a tracking device and a driving device. The tracking device is disposed on the grid structure 4 and is used to obtain information about the solar radiation intensity. The driving device is used to drive the second deflection structure 3 to rotate relative to the first deflection structure 2 around the second rotation axis according to the obtained information about the solar radiation intensity, so as to drive the grid structure 4 to deflect.

[0095] Specifically, the tracking device includes radiation sensors, such as... Figure 6 As shown, each second rod 42 has a first end 421 and a second end 422. The first end 421 is connected to the second connector 44. A radiation sensor is located at the second end 422 of any second rod 42. The radiation sensor includes multiple sub-sensors in different orientations. Each sub-sensor is electrically connected to the control module. The sub-sensors are electrically connected to the drive device to detect solar radiation and generate a corresponding solar voltage. The drive device is used to drive the second deflection structure 3 to rotate according to the multiple solar voltages, so that the grid structure 4 deflects in the direction of the radiation sensor corresponding to the largest solar voltage.

[0096] For example, a radiation sensor is installed on one of the four directions (east, west, south, and north) of the space frame structure 4. The radiation sensor includes four sub-sensors facing the four directions. When the solar voltage generated by the sub-sensor in the east direction is the maximum, the driving device drives the second deflection structure 3 to rotate around the second axis along the third direction Y1, causing the space frame structure 4 to deflect eastward. When the solar voltage generated by the sub-sensor in the west direction is the maximum, the driving device drives the second deflection structure 3 to rotate around the second axis along the fourth direction Y2, causing the space frame structure 4 to deflect westward. When the solar voltage generated by the sub-sensor in the south direction is the maximum, the first deflection structure 2 is adjusted to rotate around the first axis along the second direction X2, causing the space frame structure 4 to deflect southward. When the solar voltage generated by the sub-sensor in the north direction is the maximum, the first deflection structure 2 is adjusted to rotate around the first axis along the first direction X1, causing the space frame structure 4 to deflect northward.

[0097] In some embodiments, the tracking device is located at the end of the second rod 42 away from the support structure 1, so that the distance between tracking devices in different directions is greater and more directionally representative.

[0098] In some embodiments, the photovoltaic support 100 further includes a wind speed sensor (not shown), which is electrically connected to the drive device. The wind speed sensor is used to detect wind force and generate a corresponding wind voltage. The drive device is also used to drive the second deflection structure 3 to rotate according to the wind voltage, so that the grid structure 4 deflects to its initial position. For example, when the wind voltage is greater than a preset voltage threshold, the drive device drives the second deflection structure 3 to rotate, so that the grid structure 4 deflects to its initial position. When the grid structure 4 is in its initial position, its center of gravity is relatively stable, and it has better wind resistance.

[0099] It should be noted that the initial position can be either the space frame structure 4 being in a horizontal position or the space frame structure 4 not being in a horizontal position. The initial position refers to the second deflection structure 3 returning to the position before the deflection occurred.

[0100] In some embodiments, the photovoltaic support 100 further includes a rain and snow sensor (not shown). The rain and snow sensor is electrically connected to a driving device. The rain and snow sensor is used to detect the weight covering the photovoltaic panel 200 and generate a corresponding gravitational voltage. The driving device is also used to drive the second deflection structure 3 to rotate according to the rain and snow sensor, so that the grid structure 4 is deflected to a horizontal position. For example, when the pressure voltage is greater than a preset voltage threshold, the second deflection structure 3 rotates, so that the grid structure 4 is deflected to a horizontal position. When the grid structure 4 is in a horizontal position, the center of gravity is relatively stable, and it has better wind resistance.

[0101] In some embodiments, the photovoltaic support 100 further includes a control module (not shown), which is electrically connected to a plurality of radiation sensors, wind speed sensors, rain and snow sensors, and a drive device. The control module is used to acquire information about solar voltage, wind voltage, and rain and snow pressure voltage, and control the drive device to drive the second deflection structure 3 to rotate based on the acquired information about the magnitude of solar voltage, wind voltage, and rain and snow pressure voltage.

[0102] For example, when the wind voltage is less than a preset voltage threshold, the drive device drives the second deflection structure 3 to rotate according to multiple solar voltages, so that the grid structure 4 deflects in the direction of the radiation sensor corresponding to the maximum solar voltage; when the wind voltage is greater than the preset voltage threshold, the drive device drives the second deflection structure 3 to rotate, so that the grid structure 4 deflects to a horizontal position.

[0103] Alternatively, when the rain and snow pressure voltage is less than a preset voltage threshold, the drive device drives the second deflection structure 3 to rotate according to multiple solar voltages, causing the grid structure 4 to deflect in the direction of the radiation sensor corresponding to the maximum solar voltage; when the rain and snow pressure voltage is greater than the preset voltage threshold, the drive device drives the second deflection structure 3 to rotate, causing the grid structure 4 to deflect to a horizontal position.

[0104] Combination Figure 11 As shown, in some embodiments, the process by which the photovoltaic support 100 deflects sunlight is as follows:

[0105] A tracking system is set up to track sunlight. The tracking system includes an orientation detection head (radiation sensor).

[0106] Voltage signals in different directions are generated using an orientation detection head;

[0107] The control module receives and analyzes the voltage signal acquired by the azimuth detection head, and determines the azimuth of the sunlight by analyzing the magnitude of the voltage signal at different azimuths; and

[0108] The control module drives the second deflection structure 3 to rotate based on the analysis results.

[0109] In other embodiments, the photovoltaic support 100 deflects according to wind force as follows:

[0110] Detect wind force and use wind speed sensors to generate voltage signals in different directions;

[0111] The control module receives and analyzes the voltage signal acquired by the wind speed sensor;

[0112] No action is taken if the voltage signal acquired by the wind speed sensor does not reach the set value; and

[0113] When the voltage signal acquired by the wind speed sensor reaches the set value, the second deflection structure 3 is driven to rotate, causing the grid structure 4 to deflect to the initial position (the initial position is the position after the user has adjusted and fixed the first adjustment component 5).

[0114] In some other embodiments, the photovoltaic support 100 deflects according to the accumulation of rain and snow as follows:

[0115] Detect wind force and use rain and snow sensors to generate voltage signals from different directions;

[0116] The control module receives and analyzes the voltage signals acquired by the rain and snow sensors;

[0117] No action is taken if the voltage signal acquired by the rain and snow sensor does not reach the set value; and

[0118] When the voltage signal acquired by the rain and snow sensor reaches the set value, the second deflection structure 3 is driven to rotate, causing the grid structure 4 to deflect to a safe position.

[0119] In general, the photovoltaic support 100 can determine and drive the grid structure 4 based on the pressure generated by at least one of sunlight, wind, rain and snow. However, it is not limited to this. It can also make a comprehensive judgment by combining any two of them, or by combining sunlight, wind, rain and snow.

[0120] A photovoltaic device according to a second aspect of this application includes a photovoltaic panel 200 and a photovoltaic support 100 according to a first aspect of this application, wherein the photovoltaic panel 200 is mounted on the grid structure 4 of the photovoltaic support 100.

[0121] The photovoltaic equipment according to the embodiments of this application, by setting the photovoltaic bracket 100 of the first aspect embodiment of this application, has the same technical effect. That is, by setting the first adjustment component 5 with multiple gears to adjust the angle of the deflection structure, the grid structure 4 adjusts the angle accordingly, thereby changing the orientation and tilt angle of the photovoltaic panel 200, so that the photovoltaic panel 200 can face the sunlight at the best angle, improving the photovoltaic power generation efficiency, extending the service life of the photovoltaic bracket 100, and the photovoltaic bracket 100 is easy to operate.

[0122] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
