Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, specifically to an adjustable tilt support assembly for agricultural-photovoltaic complementary photovoltaic systems. Background Technology

[0002] In agricultural-solar hybrid power generation systems, the installation and support of photovoltaic modules need to be adapted to the synergistic needs of agricultural planting and photovoltaic power generation. The related support components are the core components connecting photovoltaic panels and greenhouse structures. They are widely used in composite scenarios that take into account both crop growth and solar energy utilization, and play a key role in supporting photovoltaic panels, ensuring their stable operation, and adapting to environmental conditions.

[0003] Existing technologies include photovoltaic (PV) support structures connected to greenhouse frames, but these connections lack reliability. Long-term use or environmental factors can easily lead to PV panel displacement, affecting the overall installation stability. Furthermore, while existing adjustable-tilt PV supports offer angle adjustment, their mechanisms are not robust enough to flexibly and precisely adjust both horizontal orientation and tilt angle. This makes them ill-suited to adapting to changes in solar altitude angles and time of day, limiting the PV panels' solar energy absorption efficiency. Regarding winter snow removal, while existing PV supports or associated snow removal structures can attempt to clear snow, some structures rely solely on gravity or simple shaking, failing to completely remove the snow. Accumulated snow can compress the module structure or obstruct PV panels, impacting solar power generation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adjustable tilt bracket assembly for agricultural-photovoltaic complementary systems. This solves the technical problem that while the aforementioned photovoltaic brackets or associated snow removal structures can attempt to handle snow accumulation, some structures can only rely on their own weight or simple shaking to remove snow, making it difficult to completely remove the snow. Furthermore, snow accumulation can easily compress the component structure or obstruct the photovoltaic panels, affecting solar power generation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable tilt bracket assembly for agricultural-photovoltaic complementary photovoltaic systems, comprising: a bracket and a sleeve, wherein the sleeve is rotatably disposed at the bottom of the bracket, a first driving member is disposed between the sleeve and the bracket, a photovoltaic fixing frame is rotatably disposed outside the bracket, a second driving frame is directly disposed between the photovoltaic fixing frame and the bracket, a support arm is disposed at the bottom of the sleeve, and a limiting seat is disposed at the bottom of the support arm;

[0006] An assembly plate is provided on the outside of the support arm, and snow removal mechanisms are evenly arranged on the outside of the assembly plate. A guide plate is provided at the bottom of the photovoltaic fixing frame. The snow removal mechanism includes a square box, a piston is slidably connected to the inner cavity of the square box, an air pump is connected to the bottom of the square box, and a spring is directly connected to the piston and the square box.

[0007] The piston is externally connected to a pull rope, and the other end of the pull rope is connected to the photovoltaic fixing frame. The upper and lower ends of the square box are respectively connected to a second one-way valve tube and a first one-way valve tube. The exhaust end of the second one-way valve tube is connected to an exhaust pipe. The exhaust pipe is inserted into the outside of the photovoltaic fixing frame. The inner cavity of the square box is equipped with a heater.

[0008] The photovoltaic panels are placed inside the photovoltaic fixing frame and secured to ensure stable installation and prevent displacement during operation. The limiting seats are fixed to the outside of the greenhouse frame to achieve a reliable connection between the modules and the greenhouse, ensuring installation stability. Activating the first drive unit rotates the support bracket, adjusting the overall horizontal orientation of the photovoltaic fixing frame. Activating the second drive unit changes the angle of the photovoltaic fixing frame, allowing for flexible adjustment of the photovoltaic panel tilt angle according to different seasons and times of day, maximizing solar energy reception and improving power generation efficiency.

[0009] When snow accumulates on the outside of the photovoltaic mounting frame in winter, the second drive frame is activated to repeatedly shake the photovoltaic mounting frame. The photovoltaic mounting frame, together with the deflector plate, shakes off the snow, preventing the snow from accumulating on the outside of the photovoltaic mounting frame and compressing the module structure. At the same time, it prevents the snow from blocking the photovoltaic panels and affecting the collection and power generation.

[0010] When the photovoltaic mounting frame vibrates, pulling the rope moves the piston. The piston's movement within the square box, combined with the first one-way valve, ensures stable air intake, while the second one-way valve directs exhaust. Simultaneously, the heater activates to heat the exhaust gas, which quickly melts residual snow and prevents icing. Finally, the gas is precisely discharged through the exhaust pipe to areas prone to snow accumulation, thoroughly cleaning the snow outside the guide plate and further improving the overall snow removal effect of the device, ensuring the normal operation of the photovoltaic modules in winter. An air pump assists in the gas circulation within the square box, and a spring drives the piston to quickly return to its original position, ensuring continuous and efficient air intake and exhaust processes.

[0011] Preferably, a control module is provided on the outside of the box, and the input terminal of the control module is connected to the air pump and the heater respectively through lines. Furthermore, a communication module and a signal processing module are provided on the outside of the control module. The control module can centrally regulate the start and stop of the air pump and the heater and their operating power. The communication module can realize remote control and data transmission, making it convenient for users to monitor the equipment's operating status in real time. The signal processing module can quickly respond to external trigger signals, realize the automated start of snow removal actions, reduce manual inspection and operation costs, and improve the ease of use of the components.

[0012] Preferably, the first driving component includes a motor, the output end of which is connected to a first gear, and the first gear is externally meshed with a gear ring. The gear ring is connected to a bracket, and the first driving component is connected to a sleeve via the bracket. The sleeve is connected to the bracket via a bearing. The motor provides stable power, and the meshing transmission between the first gear and the gear ring ensures smooth rotation of the bracket and high angle adjustment accuracy. The bearing connection reduces rotational friction between the sleeve and the bracket, reduces component wear, extends the service life of the driving mechanism, and improves the smoothness of angle adjustment.

[0013] Preferably, the second drive frame includes a motor, the output end of which is connected to a second gear. A rack is externally meshed with the second gear, and the other end of the rack is connected to the photovoltaic fixing frame via a hinge. A guide frame is provided in the inner cavity of the support frame, and the inner cavity of the guide frame is slidably connected to the outer side of the rack. A locking shaft for locking the rack is inserted into the inner cavity of the guide frame. The motor drives the second gear to mesh with the rack, thereby driving the photovoltaic fixing frame to achieve tilt angle adjustment. The guide frame limits and guides the movement trajectory of the rack, preventing the rack from deviating and causing adjustment jamming. The locking shaft can lock the rack after the tilt angle is adjusted to the correct position, preventing the photovoltaic fixing frame from deviating due to external force and ensuring tilt angle stability. The hinge allows the photovoltaic fixing frame to rotate more flexibly, adapting to different tilt angle adjustment needs.

[0014] Preferably, the limiting seat is directly connected to the support arm with a base.

The base enhances the connection strength between the limiting seat and the support arm. The shape of the groove is adapted to the greenhouse frame and can fit tightly against the surface of the frame. After the pin is inserted into the groove, it firmly locks the limiting seat and the greenhouse frame, preventing the components from loosening and falling off under the action of external forces such as wind and rain. At the same time, it is compatible with greenhouse frames of different specifications, improving the versatility of component installation.

[0015] Preferably, the inner cavity of the photovoltaic fixing frame is provided with an assembly groove for accommodating the photovoltaic panel. The inner cavity of the assembly groove is provided with a rubber pad and a fixing hole is provided in the inner cavity of the assembly groove. The assembly groove provides precise installation positioning for the photovoltaic panel, the rubber pad has a buffering and shock-absorbing function, which can absorb the vibration and impact force during transportation and use, and protect the edges and surface of the photovoltaic panel from damage. The fixing hole facilitates the quick fixing of the photovoltaic panel with fasteners such as bolts, improving assembly efficiency, while ensuring the stability of the photovoltaic panel after installation and avoiding loosening during long-term use.

[0016] Preferably, the guide plate has a guide groove on its exterior and a coating layer on its top. The two sides of the guide plate are designed to be inclined. The guide groove can guide the shaken snow to slide down along a fixed path, avoiding the snow from accumulating messily on the surface of the guide plate. The inclined design on both sides further utilizes gravity to accelerate the snow sliding down. The top coating layer reduces the adhesion between the snow and the surface of the guide plate, reduces snow residue, improves the smoothness of snow shaking, and assists the snow removal mechanism to achieve a more thorough snow removal effect.

[0017] Preferably, the inner cavity of the photovoltaic fixing frame is provided with reinforcing ribs, and the inner cavity of the photovoltaic fixing frame is provided with a guide groove. The back of the photovoltaic fixing frame is connected to the bracket through a hinge. The reinforcing ribs significantly improve the structural strength and deformation resistance of the photovoltaic fixing frame, which can withstand the impact of external forces such as wind and snow pressure and vibration, and extend the service life of the frame. The guide groove helps to drain the snow and rainwater in the inner cavity of the frame, avoiding water and snow accumulation that could cause frame corrosion or increase weight load. The hinge ensures that the photovoltaic fixing frame and the bracket can rotate flexibly, ensuring that the tilt angle adjustment function can be smoothly realized.

[0018] Preferably, the snow removal mechanism has at least five sets, and the square box is connected to the assembly plate by bolts. A sealing sleeve is provided at the junction of the square box and the pull rope, and a guide wheel is provided on the outside of the square box, with the outside of the guide wheel connected to the pull rope.

The bolt connection method facilitates the disassembly, maintenance and replacement of the snow removal mechanism, reducing the later operation and maintenance costs. The sealing sleeve prevents gas leakage in the inner cavity of the square box, ensures the gas supply pressure, and ensures the exhaust snow removal effect. The guide wheel guides and supports the pull rope, reduces friction and wear during the movement of the pull rope, and ensures the accuracy of the pull rope pulling the piston movement.

[0019] Preferably, the piston includes a movable plug, and a guide plate is provided on the back of the movable plug. The outer side of the guide plate is connected to the inner cavity of the square box, and an exhaust hole is provided on the outer side of the square box. The guide plate ensures that the movable plug moves in a straight line in the inner cavity of the square box, avoiding piston jamming or deviation, and ensuring a stable and continuous air intake and exhaust process. The exhaust hole can help adjust the air pressure in the inner cavity of the square box, quickly balance the inner cavity pressure when the piston resets, improve the smoothness of piston movement, and further ensure the working efficiency of the snow removal mechanism.

[0020] Compared with the prior art, the present invention provides an adjustable tilt angle support assembly for agricultural-solar complementary photovoltaic systems, which has the following beneficial effects:

[0021] The adjustable tilt bracket assembly of this agricultural-solar hybrid photovoltaic system is reliably connected to the greenhouse frame via a limiting seat, preventing the photovoltaic panels from shifting during operation and ensuring overall installation stability. With the cooperation of the first drive component and the second drive frame, the horizontal orientation and tilt angle of the photovoltaic fixing frame can be flexibly adjusted to adapt to different solar altitude angles in different seasons and at different times of day, helping the photovoltaic panels maximize solar energy reception and thus improve power generation efficiency.

The upper and lower ends of the square box 61 are respectively connected to a second one-way valve pipe 66 and a first one-way valve pipe 64. The exhaust end of the second one-way valve pipe 66 is connected to an exhaust pipe 67. The exhaust pipe 67 is inserted into the outside of the photovoltaic fixing frame 4. A heater 69 is provided in the inner cavity of the square box 61.

[0033] The photovoltaic panels are placed inside the photovoltaic fixing frame 4 and secured to ensure stable installation and prevent displacement during operation. The limiting seat 13 is fixed to the outside of the greenhouse frame to achieve a reliable connection between the module and the greenhouse, ensuring installation stability. Activating the first driving component 3 drives the bracket 1 to rotate, adjusting the overall horizontal orientation of the photovoltaic fixing frame 4. Activating the second driving frame 5 changes the angle of the photovoltaic fixing frame 4, allowing for flexible adjustment of the photovoltaic panel tilt angle according to different seasons and time of day, maximizing solar energy reception and improving power generation efficiency.

[0034] Please see Figure 6 and Figure 5 When snow accumulates on the outside of the photovoltaic fixing frame 4 in winter, the second drive frame 5 is activated to drive the photovoltaic fixing frame 4 to shake repeatedly. The photovoltaic fixing frame 4, together with the guide plate 7, shakes off the snow on the outside, preventing the snow from accumulating on the outside of the photovoltaic fixing frame 4 and compressing the module structure, while also preventing the snow from blocking the photovoltaic panel and affecting the collection and power generation.

[0035] When the photovoltaic mounting frame 4 vibrates, the pull rope 68 drives the piston 62 to move. The piston 62 moves within the square box 61, coordinating with the first one-way valve pipe 64 to ensure stable air intake and directional exhaust through the second one-way valve pipe 66. Simultaneously, the heater 69 is activated to heat the exhaust gas. The heated gas can quickly melt residual snow and prevent freezing. Finally, it is precisely discharged through the exhaust pipe 67 to areas prone to snow accumulation, thoroughly cleaning the snow outside the guide plate 7, further improving the overall snow removal effect of the device and ensuring the normal operation of the photovoltaic modules in winter. The air pump 63 assists in the gas circulation within the square box 61, and the spring 65 can drive the piston 62 to quickly return to its original position, ensuring continuous and efficient air intake and exhaust processes.

[0036] The square box 61 is equipped with a control module, and the input terminals of the control module are connected to the air pump 63 and the heater 69 via lines. The control module is also equipped with a communication module and a signal processing module.

The gear ring 31 is connected to the bracket 1. The first driving component 3 is connected to the sleeve 2 through the bracket. The sleeve 2 is connected to the bracket 1 through a bearing. The motor provides stable power. The meshing transmission between the first gear and the gear ring 31 ensures that the bracket 1 rotates smoothly and has high angle adjustment accuracy. The bearing connection reduces rotational friction between the sleeve 2 and the bracket 1, reduces component wear, extends the service life of the driving mechanism, and improves the smoothness of angle adjustment.

[0038] The second drive frame 5 includes a motor, the output end of which is connected to a second gear. The second gear is externally meshed with a rack 51. The other end of the rack 51 is connected to the photovoltaic fixing frame 4 via a hinge. The inner cavity of the bracket 1 is provided with a guide frame, the inner cavity of which is slidably connected to the outer cavity of the rack 51. A locking shaft for locking the rack 51 is inserted into the inner cavity of the guide frame. The motor drives the second gear to mesh with the rack 51, thereby driving the photovoltaic fixing frame 4 to achieve tilt angle adjustment. The guide frame plays a limiting and guiding role in the movement trajectory of the rack 51, preventing the rack 51 from deviating and causing adjustment jamming. The locking shaft can lock the rack 51 after the tilt angle is adjusted to the correct position, preventing the photovoltaic fixing frame 4 from deviating due to external force and ensuring tilt angle stability. The hinge allows the photovoltaic fixing frame 4 to rotate more flexibly, adapting to different tilt angle adjustment needs.

[0039] The limiting seat 13 is directly connected to the support arm 11 by the base 12. The inner cavity of the limiting seat 13 has a groove for accommodating the greenhouse frame, and a pin is inserted into the inner cavity of the groove. The base 12 enhances the connection strength between the limiting seat 13 and the support arm 11. The shape of the groove is adapted to the greenhouse frame and can fit tightly against the surface of the frame. After the pin is inserted into the groove, the limiting seat 13 and the greenhouse frame are firmly locked, preventing the components from loosening and falling off under the action of external forces such as wind and rain. At the same time, it is compatible with greenhouse frames of different specifications, improving the versatility of component installation.

[0040] The inner cavity of the photovoltaic fixing frame 4 is provided with an assembly slot for accommodating photovoltaic panels.

The fixing hole facilitates the quick fixing of the photovoltaic panels with bolts and other fasteners, improving assembly efficiency and ensuring the stability of the photovoltaic panels after installation, thus preventing loosening during long-term use.

[0041] The guide plate 7 has a guide groove on its outside and a coating layer on its top. The two sides of the guide plate 7 are designed to be inclined. The guide groove can guide the falling snow to slide down along a fixed path, avoiding the snow from piling up messily on the surface of the guide plate 7. The inclined design on both sides further utilizes gravity to accelerate the snow sliding down. The coating layer on the top reduces the adhesion between the snow and the surface of the guide plate 7, reduces snow residue, improves the smoothness of snow shaking, and assists the snow removal mechanism 6 to achieve a more thorough snow removal effect.

[0042] The photovoltaic fixing frame 4 has reinforcing ribs in its inner cavity and a guide groove in its inner cavity.

The guide groove helps to drain snow and rainwater from the inner cavity of the frame, preventing water and snow accumulation from causing frame corrosion or increasing weight load. The hinge ensures that the photovoltaic fixing frame 4 and the bracket 1 can rotate flexibly, ensuring that the tilt angle adjustment function can be realized smoothly.

The bolt connection method facilitates the disassembly, maintenance and replacement of the snow removal mechanism 6, reducing the later operation and maintenance costs. The sealing sleeve prevents gas leakage in the cavity of the square box 61, ensures the gas supply pressure, and ensures the exhaust snow removal effect. The guide wheel guides and supports the pull rope 68, reduces the friction and wear of the pull rope 68 during movement, and ensures the accuracy of the pull rope 68 pulling the piston 62.

The outside of the guide plate is connected to the inner cavity of the square box 61, and an exhaust hole is provided on the outside of the square box 61. The guide plate ensures that the movable plug moves in a straight line in the inner cavity of the square box 61, preventing the piston 62 from getting stuck or deviating, and ensuring a stable and continuous air intake and exhaust process. The exhaust hole can help adjust the air pressure in the inner cavity of the square box 61, quickly balance the inner cavity pressure when the piston 62 resets, improve the smoothness of the piston 62's movement, and further ensure the working efficiency of the snow removal mechanism 6.

[0045] In this scheme, the photovoltaic panel is placed in the inner cavity of the photovoltaic fixing frame 4 and fixed. The limiting seat 13 is fixed to the outside of the greenhouse frame. The first driving component 3 is started to drive the bracket 1 to rotate. The second driving frame 5 is started to change the angle of the photovoltaic fixing frame 4.

[0046] When snow accumulates on the outside of the photovoltaic fixed frame 4 in winter, the second drive frame 5 is activated to drive the photovoltaic fixed frame 4 to shake repeatedly. The photovoltaic fixed frame 4, together with the guide plate 7, shakes off the snow on the outside, preventing the snow from accumulating on the outside of the photovoltaic fixed frame 4. At the same time, when the photovoltaic fixed frame 4 shakes, it pulls the pull rope 68 to drive the piston 62 to move. The piston 62 moves in the inner cavity of the square box 61 and cooperates with the first one-way valve pipe 64 to allow air to enter and the second one-way valve pipe 66 to allow air to exit. At the same time, the heater 69 is activated to heat the exhaust gas.
