Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel technology, specifically to an active tracking rooftop photovoltaic panel support device. Background Technology

[0002] Energy is the foundation upon which modern society depends for survival and development. To address the energy crisis, countries are actively researching new energy technologies, especially renewable energy sources such as solar, wind, and bioenergy. Renewable energy is inexhaustible and environmentally friendly, and has received high attention from countries around the world. However, renewable energy is geographically dispersed, its production is discontinuous, random, volatile, and uncontrollable. The centralized management of traditional power grids is difficult to adapt to the requirements of large-scale utilization of renewable energy. The most effective way to utilize renewable energy is through distributed "on-site collection, on-site storage, and on-site use."

[0003] In photovoltaic (PV) power generation systems, single-axis tracking brackets are among the most commonly used PV array brackets. Because these brackets can track changes in the sun's azimuth angle during the day, the total annual power generation of PV modules using this type of bracket is 10%-15% higher than that of PV modules using brackets with an optimal fixed tilt angle. Traditional rooftop PV panel brackets are mostly fixed, with the PV panel angle fixed and unable to adjust according to changes in the sun's position. This results in the PV panels not always receiving sunlight at the optimal angle, limiting power generation efficiency. Although some tracking brackets exist, they suffer from complex structures, high costs, and poor reliability, making them unsuitable for large-scale application in rooftop PV systems. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: an active tracking rooftop photovoltaic panel support device, comprising: a mobile frame assembly, which is used for transporting and moving photovoltaic panels on the rooftop, wherein the bottom of the mobile frame assembly is rotatably mounted with wheels, and a processor is fixedly installed inside the mobile frame assembly;

[0005] A drive assembly for adjusting the angle of the photovoltaic panel is rotatably mounted on the top of the mobile frame assembly, and a support rod is fixedly mounted at the axis of the drive assembly.

[0006] A support assembly is used for positioning and installing photovoltaic (PV) panels. The PV panels are fixedly installed inside the support assembly, and a light sensor and a clock module are fixedly installed on the surface of the PV panels. The light sensor and clock module are connected to a processor via electrical signals. The support assembly is fixedly mounted on the outer surface of the support rod. When workers install the PV panels on the roof, the support assembly secures the PV panels. The light sensor, installed near the PV panels, is used to detect the intensity and direction of sunlight in real time. The clock module provides time information. Combined with geographical location information, the processor can calculate the theoretical position of the sun at different times. When the direction of sunlight detected by the light sensor does not match the current angle of the PV panel, the processor calculates the angle that needs adjustment based on the deviation value and sends a command to the drive motor to achieve automatic tracking of the PV panel.

[0007] Preferably, the support assembly includes a sleeve, a support plate rotatably mounted on the top of the sleeve, and waterproof guide frames fixedly mounted on both sides of the top of the support plate. Two waterproof guide frames are provided, each fixedly mounted at one end of the top of the support plate. Each waterproof guide frame has a heat dissipation groove inside, and water guide strips are fixedly mounted on both sides of the outer surface of the waterproof guide frame. The water guide strips have drainage channels inside, and extended drainage components are fixedly mounted inside the drainage channels. The photovoltaic panel adjusts its angle via a light sensor and a clock module, causing the drive assembly to rotate the support rod. In rainy or snowy weather, rainwater flows outwards along the surface of the photovoltaic panel to the drainage channels on the surface of the water guide strips, thus diverting rainwater during heavy rainfall. The rainwater is then guided through the drainage channels to the extended drainage components to prevent rainwater accumulation on the photovoltaic panel surface.

[0008] Preferably, the bushing is fixedly installed on the top of the support rod, and adjusting frames are rotatably installed on both sides of the bottom of the support plate. A collar is rotatably installed on the surface of the adjusting frame, and the collar is fitted onto the outer surface of the support rod. The waterproof guide frame is fixedly installed on the bottom of the photovoltaic module. Because the rooftop is relatively open, snow will accumulate on the surface of the photovoltaic panel during snowy weather. At this time, the tilted photovoltaic panel, affected by the weight of the snow, causes the bushing and adjusting frames to rotate and tilt, thereby causing the snow covering the photovoltaic panel to slide off. This facilitates snow removal and prevents excessive snow accumulation from affecting the photovoltaic panel's power generation efficiency.

[0009] Preferably, the extended drainage component includes a sleeve block. The outer surface of the sleeve block is provided with an inclined block, and the interior of the sleeve block has a positioning cavity. A drainage groove is fixedly installed inside the positioning cavity, and an extension groove is fixedly installed on the surface of the drainage groove. A fitting block is fixedly installed on the outer surface of the extension groove. The sleeve block is designed as a triangular block structure. Due to its structural characteristic that its shape cannot be changed after its three sides are fixed, it can firmly restrain the photovoltaic panel in a preset position, preventing the photovoltaic panel from shifting, deviating, or shaking in the horizontal, vertical, or inclined directions. The double-sided layout further strengthens the constraint, ensuring that the photovoltaic panel is subjected to symmetrical forces on both sides, preventing tilting caused by loosening on one side. Rainwater enters the extension groove along the drainage groove. The extension groove is designed as a semi-circular arc, allowing rainwater to flow along the extension groove into the positioning cavity. At this time, the inclined drainage groove in the positioning cavity discharges the rainwater outward, allowing the rainwater to slide off quickly, ensuring that rainwater does not accumulate in large quantities on the panel surface and reducing the risk of leakage.

[0010] Preferably, the bonding block is fixedly installed inside the drainage channel, and the drainage channel is connected to the drainage channel through the bonding block and the extension channel.

[0011] Preferably, the drive assembly includes a chassis. A first engaging rod is fixedly installed on the side of the chassis. A circular shaft is rotatably installed inside the chassis. Drive wheels are rotatably installed on the surface of the circular shaft. Four drive wheels are provided. Inner plates are rotatably installed on the surfaces of the four drive wheels. A second engaging rod is fixedly installed on the surface of the inner plates. The second engaging rod engages with the drive wheels through the inner plates. A positioning seat is fixedly installed on the top of the inner plates. A motor is fixedly installed on the bottom of the inner plates. When the photovoltaic panel adjusts its angle via a light sensor and a clock module, the processor drives the motor at the bottom of the inner plates, causing the motor output to rotate the inner plates. The inner plates then engage with the drive wheels through the second engaging rods installed on the outside of the inner plates, causing the drive wheels to rotate within the chassis. This allows for precise adjustment of the photovoltaic panel's angle, ensuring it always faces the sun. This reduces complex transmission components, lowers the probability of failure, improves system stability and reliability, and also facilitates installation and maintenance.

[0012] Preferably, the chassis is fixedly installed on the top of the mobile frame assembly, and the positioning seat is fixedly sleeved on the outer surface of the support rod.

[0013] Preferably, the mobile frame assembly includes a base support, a connecting ring fixedly installed on the top of the base support, and a movable seat rotatably mounted on the outer surface of the base support. Three sets of movable seats are arranged in a circumferential pattern on the surface of the base support. When workers need to install photovoltaic panels on the rooftop, the limited area on the roof presents limitations for moving and transporting the panels. Therefore, when moving the photovoltaic panels, workers push the photovoltaic support frame, causing the wheels to rotate and the movable seats to move in multiple directions, thereby improving the efficiency of moving the photovoltaic panels.

[0014] Preferably, the movable base includes a fixed block, an external frame is fixedly installed inside the fixed block, a snap-fit ​​block is fixedly installed on the outer surface of the external frame, the snap-fit ​​block is adapted to the fixed block, a base frame is fixedly installed on the outer surface of the snap-fit ​​block, a snap-fit ​​block is fixedly installed on the top of the base frame, a protective plate is fixedly installed inside the snap-fit ​​block, and an anti-collision groove is provided at the bottom of the protective plate. When the traveling wheels encounter an obstacle, the anti-collision groove at the bottom of the protective plate collides with the obstacle and is compressed, deforming inward to buffer the impact force and protect the traveling wheels, thereby preventing damage to the photovoltaic bracket from collisions and affecting the stability of the photovoltaic panel support.

[0015] Preferably, the fixing block is fixedly installed on the outer surface of the base support, the base frame is fixedly installed on both sides of the top of the walking wheel, and the surface of the protective plate away from the anti-collision groove is fixedly connected to the snap-fit ​​block.

[0016] This invention provides an active tracking rooftop photovoltaic panel support device. It has the following beneficial effects:

[0017] I. This active tracking rooftop photovoltaic panel support device, when installed on the roof by workers, uses support components to fix the photovoltaic modules. A light sensor is installed near the photovoltaic panel to detect the intensity and direction of sunlight in real time. A clock module provides time information, and combined with geographical location information, the processor can calculate the theoretical position of the sun at different times. When the direction of the sunlight detected by the light sensor does not match the current angle of the photovoltaic panel, the processor calculates the angle that needs to be adjusted based on the deviation value and sends a command to the drive motor to achieve automatic tracking of the photovoltaic panel.

[0018] 2. This active tracking rooftop photovoltaic panel support device uses a light sensor and a clock module to adjust the angle of the photovoltaic panel, so that the drive component drives the support rod to rotate. In rainy or snowy weather, rainwater flows outward along the surface of the photovoltaic panel to the drainage channel opened on the surface of the water guide strip, so as to divert the rainwater when the rainfall is heavy. The rainwater is guided to the extended drainage component through the drainage channel to avoid rainwater accumulation on the surface of the photovoltaic panel.

[0019] Third, this active tracking rooftop photovoltaic panel support device utilizes the fact that, due to the openness of the rooftop during snowy weather, snow accumulates on the surface of the photovoltaic panels. The weight of the snow causes the inclined photovoltaic panels to rotate and tilt, allowing the snow to slide off, facilitating snow removal and preventing excessive snow accumulation that could affect the photovoltaic panel's power generation efficiency. Rainwater flows along the drainage channel into the extension channel, which is designed in a semi-circular arc shape. This allows the rainwater to flow into the positioning cavity, where an inclined drainage channel directs the rainwater outwards, ensuring rapid drainage and preventing excessive accumulation on the panel surface, thus reducing the risk of leakage.

[0020] IV. This active tracking rooftop photovoltaic panel support device requires workers to install photovoltaic panels on the roof. Due to the limited area on the roof, there are limitations in moving and transporting the photovoltaic panels. Therefore, when moving the photovoltaic panels, workers push the photovoltaic support, causing the traveling wheels to rotate and the moving base to move in multiple directions to improve the moving efficiency of the photovoltaic panels. When the traveling wheels encounter obstacles, the anti-collision grooves set at the bottom of the protective plate collide with the obstacles and are squeezed and deformed inward to buffer the impact force and protect the traveling wheels, so as to avoid damage to the photovoltaic support and affect the stability of the photovoltaic panel support.

[0021] V. This active tracking rooftop photovoltaic panel support device, when the photovoltaic panel adjusts its angle via a light sensor and clock module, the processor drives the motor at the bottom of the inner plate, causing the motor output to rotate the inner plate. The inner plate then engages with the drive wheel via a second meshing rod installed on the outside of the inner plate, allowing the drive wheel to rotate within the chassis. This allows for precise adjustment of the photovoltaic panel's angle, ensuring it always faces the sun. This reduces the complexity of transmission components, lowers the probability of malfunctions, and improves the system's stability and reliability. It also facilitates installation and maintenance.

[0033] 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.

[0034] First embodiment, such as Figures 1 to 10 As shown, the present invention provides a technical solution: an active tracking rooftop photovoltaic panel support device, comprising: a mobile frame group 5, which is used for transporting and moving photovoltaic panels on the rooftop, with a walking wheel 6 rotatably installed at the bottom of the mobile frame group 5, and a processor 7 fixedly installed inside the mobile frame group 5;

[0035] The mobile frame assembly 5 includes a base support 51, with a connecting ring 53 fixedly installed on the top of the base support 51. Three sets of mobile seats 52 are rotatably mounted on the outer surface of the base support 51, arranged in a circumferential pattern on the surface of the base support 51. When workers need to install photovoltaic panels on the rooftop, the limited space on the roof presents limitations for moving and transporting the panels. Therefore, when moving the photovoltaic panels, workers push the photovoltaic support frame, causing the wheels 6 to rotate, which in turn drives the mobile seats 52 to move in multiple directions, improving the efficiency of moving the photovoltaic panels.

[0036] Drive component 4, which is used for photovoltaic panel angle adjustment, is rotatably mounted on the top of the mobile frame assembly 5, and a support rod 3 is fixedly mounted at the axis of drive component 4.

[0037] The drive assembly 4 includes a chassis 41. A first engagement rod 47 is fixedly installed on the side inside the chassis 41. A round shaft 46 is rotatably installed inside the chassis 41. A drive wheel 45 is rotatably installed on the surface of the round shaft 46. There are four drive wheels 45. An inner plate 43 is rotatably installed on the surface of the four drive wheels 45. A second engagement rod 44 is fixedly installed on the surface of the inner plate 43. The second engagement rod 44 engages with the drive wheel 45 through the inner plate 43. A positioning seat 42 is fixedly installed on the top of the inner plate 43. A motor is fixedly installed on the bottom of the inner plate 43. When the photovoltaic panel adjusts its angle via a light sensor and a clock module, the processor 7 drives a motor at the bottom of the inner plate 43, causing the motor output to rotate the inner plate 43. The inner plate 43 is then engaged with a drive wheel 45 via a second meshing rod 44 mounted on its outer side, allowing the drive wheel 45 to rotate within the chassis 41. This allows for precise adjustment of the photovoltaic panel's angle, ensuring it always faces the sun. This reduces the complexity of transmission components, lowers the probability of malfunctions, and improves the system's stability and reliability. It also facilitates installation and maintenance.

[0038] The chassis 41 is fixedly installed on the top of the mobile frame assembly 5, and the positioning seat 42 is fixedly sleeved on the outer surface of the support rod 3.

[0039] Support component 2 is used for positioning and installing photovoltaic panels. Photovoltaic module 1 is fixedly installed inside support component 2, and a light sensor and clock module are fixedly installed on the surface of photovoltaic module 1. The light sensor and clock module are connected to processor 7 via electrical signals. Support component 2 is fixedly installed on the outer surface of support rod 3. When workers install the photovoltaic panels on the roof, photovoltaic module 1 is fixed using support component 2. The light sensor is installed near the photovoltaic panel to detect the intensity and direction of sunlight in real time. The clock module provides time information. Combined with geographical location information, processor 7 can calculate the theoretical position of the sun at different times. When the direction of sunlight detected by the light sensor does not match the current angle of the photovoltaic panel, processor 7 calculates the angle that needs to be adjusted based on the deviation value and sends a command to the drive motor to achieve automatic tracking of the photovoltaic panel.

[0040] The support assembly 2 includes a sleeve pipe 22, on the top of which a support plate 24 is rotatably mounted. Waterproof guide frames 21 are fixedly mounted on both sides of the top of the support plate 24. Two waterproof guide frames 21 are provided, each fixedly mounted at one end of the top of the support plate 24. Each waterproof guide frame 21 has a heat dissipation groove 29 inside. Water guide strips 28 are fixedly mounted on both sides of the outer surface of the waterproof guide frame 21. Drainage channels 27 are formed inside the water guide strips 28, and extension drainage components 25 are fixedly installed inside the drainage channels 27. The photovoltaic panel adjusts its angle via a light sensor and a clock module, causing the drive assembly 4 to rotate the support rod 3. In rainy or snowy weather, rainwater flows outwards along the surface of the photovoltaic panel into the drainage channels 27 on the surface of the water guide strips 28, thus diverting rainwater during heavy rainfall. The rainwater is then guided through the drainage channels 27 to the extension drainage components 25 to prevent rainwater accumulation on the photovoltaic panel surface.

[0041] The sleeve 22 is fixedly installed on the top of the support rod 3. Adjustment frames 23 are rotatably installed on both sides of the bottom of the support plate 24. A collar 26 is rotatably installed on the surface of the adjustment frame 23 and is fitted onto the outer surface of the support rod 3. The waterproof guide frame 21 is fixedly installed on the bottom of the photovoltaic module 1. Because the rooftop is relatively open, snow will cover the surface of the photovoltaic panel during snowy weather. At this time, the tilted photovoltaic panel is affected by the weight of the snow, causing the sleeve 22 and the adjustment frame 23 to rotate and tilt, thereby causing the snow covering the photovoltaic panel to slide off, making it easier to clear the snow and avoid the snow accumulation being too thick and affecting the power generation effect of the photovoltaic panel.

[0042] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 4 to 6As shown, the extended drainage component 25 includes a sleeve block 251. An inclined block 254 is provided on the outer surface of the sleeve block 251. A positioning cavity 252 is formed inside the sleeve block 251. A drainage groove 253 is fixedly installed inside the positioning cavity 252. An extension groove 256 is fixedly installed on the surface of the drainage groove 253. An adhesive block 255 is fixedly installed on the outer surface of the extension groove 256. The sleeve block 251 is designed as a triangular block structure. Due to its structural characteristic that its shape cannot be changed after its three sides are fixed, it can firmly restrain the photovoltaic panel in a preset position, preventing the photovoltaic panel from shifting, deviating, or shaking in the horizontal, vertical, or inclined directions. The double-sided layout further strengthens the constraint, ensuring that the forces on both sides of the photovoltaic panel are symmetrical, preventing tilting caused by loosening on one side. Rainwater flows into the extension channel 256 through the diversion channel 27. The extension channel 256 is designed in a semi-circular arc shape, allowing rainwater to flow into the positioning cavity 252. At this time, the inclined drainage channel 253 in the positioning cavity 252 discharges the rainwater outward, so that the rainwater can slide off quickly, ensuring that rainwater does not accumulate in large quantities on the board surface and reducing the risk of leakage.

[0043] The bonding block 255 is fixedly installed inside the drainage channel 27, and the drainage channel 27 is connected to the drainage channel 253 through the bonding block 255 and the extension channel 256.

[0044] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 10 As shown, the movable base 52 includes a fixed block 522. An external frame 521 is fixedly installed inside the fixed block 522. A snap-fit ​​block 523 is fixedly installed on the outer surface of the external frame 521. The snap-fit ​​block 523 is compatible with the fixed block 522. A base frame 527 is fixedly installed on the outer surface of the snap-fit ​​block 523. A snap-fit ​​block 525 is fixedly installed on the top of the base frame 527. A protective plate 524 is fixedly installed inside the snap-fit ​​block 525. An anti-collision groove 526 is provided at the bottom of the protective plate 524. When the traveling wheel 6 encounters an obstacle, the anti-collision groove 526 at the bottom of the protective plate 524 collides with the obstacle and is squeezed, deforming and contracting inward to buffer the impact force and protect the traveling wheel 6, so as to avoid damage to the photovoltaic bracket from collision and affect the stability of the photovoltaic panel support.

[0045] The fixing block 522 is fixedly installed on the outer surface of the base support 51, the base frame 527 is fixedly installed on both sides of the top of the walking wheel 6, and the surface of the protective plate 524 away from the anti-collision groove 526 is fixedly connected to the snap-fit ​​block 523.

[0046] In use, when the photovoltaic panels are installed on the roof by staff, the photovoltaic modules 1 are fixed by the support component 2. A light sensor is installed near the photovoltaic panels to detect the intensity and direction of sunlight in real time. The clock module provides time information, and combined with the geographical location information, the processor 7 can calculate the theoretical position of the sun at different times. When the direction of the light detected by the light sensor does not match the current angle of the photovoltaic panel, the processor 7 calculates the angle that needs to be adjusted based on the deviation value and sends a command to the drive motor to achieve automatic tracking of the photovoltaic panel.

[0047] When the photovoltaic panel adjusts its angle via a light sensor and a clock module, the processor 7 drives a motor at the bottom of the inner plate 43, causing the motor output to rotate the inner plate 43. The inner plate 43 is then engaged with a drive wheel 45 via a second meshing rod 44 mounted on its outer side, allowing the drive wheel 45 to rotate within the chassis 41. This allows for precise adjustment of the photovoltaic panel's angle, ensuring it always faces the sun. This reduces the complexity of transmission components, lowers the probability of malfunctions, and improves the system's stability and reliability. It also facilitates installation and maintenance.

[0048] The photovoltaic panel adjusts its angle through a light sensor and a clock module, causing the drive component 4 to rotate the support rod 3. In rainy or snowy weather, rainwater flows outward along the surface of the photovoltaic panel to the drainage channel 27 on the surface of the water guide strip 28, so as to divert the rainwater when the rainfall is heavy. The rainwater is guided to the extension drainage component 25 through the drainage channel 27 to avoid rainwater accumulating on the surface of the photovoltaic panel.

[0049] Because the rooftop is relatively open, snow will accumulate on the surface of the photovoltaic panels during snowy weather. The weight of the snow on the tilted photovoltaic panels causes the sleeve pipe 22 and adjustment frame 23 to rotate and tilt, allowing the snow to slide off and facilitating snow removal. This prevents excessive snow accumulation from affecting the photovoltaic panels' power generation efficiency. The sleeve block 251, with its triangular block structure, retains its shape after its three sides are fixed, firmly confining the photovoltaic panels in a preset position and preventing displacement, shifting, or shaking in horizontal, vertical, or tilting directions. The double-sided layout further strengthens the constraint, ensuring symmetrical force on both sides of the photovoltaic panels and preventing tilting caused by loosening on one side. Rainwater flows into the extension channel 256 through the diversion channel 27. The extension channel 256 is designed in a semi-circular arc shape, allowing rainwater to flow into the positioning cavity 252. At this time, the inclined drainage channel 253 in the positioning cavity 252 discharges the rainwater outward, so that the rainwater can slide off quickly, ensuring that rainwater does not accumulate in large quantities on the board surface and reducing the risk of leakage.

[0050] Workers need to install photovoltaic panels on the roof. Due to the small size of the roof area, there are limitations when moving and transporting the photovoltaic panels. Therefore, when moving the photovoltaic panels, workers push the photovoltaic bracket, causing the traveling wheels 6 to rotate, which drives the moving seat 52 to move in multiple directions to improve the moving efficiency of the photovoltaic panels. When the traveling wheels 6 encounter obstacles, the anti-collision groove 526 set at the bottom of the protective plate 524 collides with the obstacle and is squeezed and deformed inward to buffer the impact force and protect the traveling wheels 6, so as to avoid damage to the photovoltaic bracket from collision and affect the stability of the photovoltaic panel support.
