Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a photovoltaic bracket with an automatically adjustable angle. Background Technology

[0002] Photovoltaic carports exemplify the application of photovoltaic panels in daily life. Because electric vehicle photovoltaic carports can meet parking needs while providing a continuous supply of green electricity for charging electric vehicles, their use is increasing. By integrating photovoltaic modules with the carport, the photovoltaic modules directly serve as the roof, providing shade and rain protection for parked vehicles. The supporting frame for the carport roof is the photovoltaic mounting bracket. To achieve optimal sunlight exposure, the tilt angle of the photovoltaic panels needs to be adjusted to suit the light conditions during installation. For example, Chinese patent CN216565032U proposes an adjustable photovoltaic solar bracket. This device allows for angle adjustment by rotating an adjustment handle after the photovoltaic panel is mounted on an I-shaped mounting frame, improving the initial sunlight exposure of the photovoltaic panel. However, during use, solar photovoltaic mounting brackets often need to withstand strong winds, and the aforementioned technology lacks windproof design. Impacts to the photovoltaic panel surface can easily cause loosening of the mounting bracket's connecting parts, leading to damage. Furthermore, the lack of monitoring of the adjustment position results in deviations in position adjustment, affecting windproof performance. Utility Model Content

[0003] The purpose of this utility model is to provide a photovoltaic bracket with automatic angle adjustment that is strong in wind resistance, safe, highly automated, precisely adjustable, structurally stable, firmly supported, energy self-sufficient, intelligently managed, widely applicable, and highly practical.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses an automatically adjustable photovoltaic support, comprising a column, a canopy for laying photovoltaic modules rotatably connected to the top of the column via a pivot, an angle adjustment component for adjusting the angle of the canopy installed on the column, the angle adjustment component being connected to the canopy, a position sensor for monitoring the adjusted position of the canopy installed on the column, the position sensor being positioned near the connection between the canopy and the column, a locking telescopic support rod for support and locking connected to the column, and a wind speed sensor for monitoring ambient wind speed installed on the side of the canopy.

[0006] Furthermore, there are multiple locking telescopic support rods, and both ends of the locking telescopic support rods are rotatably connected to the column and the canopy through pivots.

[0007] Furthermore, the locking telescopic support rod includes an extension rod rotatably connected to the canopy at one end, and a support rod rotatably connected to the column at the other end. The extension rod is inserted into the support rod and has an external thread. The inner side wall of the support rod has an internal thread that matches the extension rod. The end of the support rod connected to the extension rod has a locking notch for providing tightening margin. A locking collar is threaded to the outer side of the support rod connected to the extension rod. The locking collar is used to tighten the end of the support rod connected to the extension rod, so that the tightened support rod and the extension rod generate a frictional force for support. A gear for driving the locking collar to rotate is engaged on the outer side of the locking collar. A drive motor for driving the gear to rotate is fixedly connected to the support rod.

[0008] Furthermore, there are multiple columns, and the number of angle adjustment components matches the number of columns. Multiple columns are arranged side by side to jointly support the scaffold.

[0009] Furthermore, the angle adjustment component is an electric telescopic rod, and the two ends of the electric telescopic rod are rotatably connected to the column and the canopy through rotating shafts, respectively.

[0010] Furthermore, the photovoltaic module is equipped with a light sensor for monitoring the angle of sunlight.

[0011] Furthermore, it also includes an energy storage electromechanical control box for energy storage and control. The energy storage electromechanical control box is electrically connected to the angle adjustment component, photovoltaic component, position sensor, light sensor and wind speed sensor respectively. The energy storage electromechanical control box is fixedly installed on the column.

[0012] Furthermore, the position sensor includes a potentiometer fixedly connected to the column, and the sliding arm of the potentiometer is rotatably connected to the scaffold via a rotating shaft.

[0013] Furthermore, the angle adjustment range of the scaffold is 0°-40°.

[0014] Furthermore, the distance between the lowest end of the canopy and the ground ranges from 4.5M to 5M.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Strong wind resistance and good safety: The system monitors the ambient wind speed in real time through a wind speed sensor. When the wind speed exceeds the preset safety threshold, the control system can automatically adjust the canopy to a safe angle (such as close to horizontal). Combined with the closed-loop feedback control of the angle adjustment component and the position sensor, the system can automatically and accurately adjust the angle of the canopy, effectively reduce wind load, prevent damage to the support structure, and improve the safety and reliability of the system under severe weather conditions.

[0017] 2. High degree of automation and precise adjustment: By monitoring the sun's position in real time through a light sensor, and combining the closed-loop feedback control of the angle adjustment component and the position sensor, the angle of the shed can be automatically and precisely adjusted to ensure that the photovoltaic modules always face the sun at the optimal angle, significantly improving the utilization rate of light energy and the power generation efficiency.

[0018] 3. Stable structure and firm support: The canopy is supported by multiple columns in parallel and is equipped with locking telescopic struts. After being adjusted to the target angle, it provides additional support and locking, enhancing the overall structural stability and preventing swaying or deformation under strong wind conditions.

[0019] 4. Energy self-sufficiency and intelligent management: Equipped with an energy storage electromechanical control box, it not only stores the electrical energy generated by the photovoltaic modules to power the angle adjustment components and various sensors, achieving energy self-sufficiency, but also integrates control functions to intelligently decide the best operating strategy based on environmental parameters such as sunlight and wind speed, achieving intelligent operation management.

[0020] 5. Wide range of applications and strong practicality: The angle adjustment range of the shed is 0°-40°, and the lowest end of the shed is 4.5M-5M above the ground. It can ensure sufficient light reception area without affecting the use of ground space, making it particularly suitable for applications such as agricultural photovoltaic integration and carport photovoltaic.

[0028] Numerous details are explored in the following description to provide a more thorough explanation of embodiments of the present invention; however, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details.

[0029] Please see Figures 1 to 3 An automatically adjustable photovoltaic bracket includes a column 1. The top of the column 1 is rotatably connected to a canopy 3 for laying photovoltaic modules 2 via a pivot. An angle adjustment component 4 for adjusting the angle of the canopy 3 is installed on the column 1 and connected to the canopy 3. A position sensor 5 for monitoring the adjusted position of the canopy 3 is installed on the column 1 and is located near the connection between the canopy 3 and the column 1. A locking telescopic support rod 6 for support and locking is connected to the column 1. A wind speed sensor 8 for monitoring the ambient wind speed is installed on the side of the canopy 3.

[0030] Please see Figure 1 and Figure 2 The number of locking telescopic support rods 6 is multiple, and the two ends of the locking telescopic support rods 6 are rotatably connected to the column 1 and the canopy 3 respectively through rotating shafts.

[0031] Please see Figure 2The locking telescopic support rod 6 includes an extension rod 61 rotatably connected at one end to the canopy 3, and a support rod 62 rotatably connected at one end to the column 1. The extension rod 61 is inserted into the support rod 62 and has an external thread. The inner side wall of the support rod 62 has an internal thread that matches the extension rod 61. The end of the support rod 62 connected to the extension rod 61 has a locking notch for providing tightening allowance. A locking collar is threaded to the outer side of the support rod 62 connected to the extension rod 61. 63. The locking collar 63 is used to tighten the end of the support rod 62 connected to the extension rod 61, so that the tightened support rod 62 and the extension rod 61 generate a frictional force for support. The outer side of the locking collar 63 is engaged with a gear 64 for driving the locking collar 63 to rotate. A drive motor 65 for driving the gear 64 to rotate is fixedly connected to the support rod 62. The length of the gear 64 is sufficient for the up and down movement of the locking collar 63 when it rotates, ensuring engagement with the locking collar 63 when it rotates.

[0032] Please see Figure 3 The number of the columns 1 is multiple, and the number of the angle adjustment components 4 matches the number of the columns 1. Multiple columns 1 are arranged side by side to jointly support the canopy 3.

[0033] Please see Figures 1 to 3 The angle adjustment component 4 is an electric telescopic rod, and the two ends of the electric telescopic rod are rotatably connected to the column 1 and the canopy 3 respectively through a rotating shaft.

[0034] The photovoltaic module 2 is equipped with a light sensor (not shown in the figure) for monitoring the angle of sunlight.

[0035] Please see Figure 1 and Figure 3 It also includes an energy storage electromechanical control box 7 for energy storage and control. The energy storage electromechanical control box 7 is electrically connected to the angle adjustment component 4, the photovoltaic module 2, the position sensor 5, the light sensor and the wind speed sensor 8 respectively. The energy storage electromechanical control box 7 is fixedly installed on the column 1.

[0036] Please see Figure 3 The position sensor 5 includes a potentiometer fixedly connected to the column 1, and the sliding arm of the potentiometer is rotatably connected to the scaffold 3 via a rotating shaft.

[0037] The angle adjustment range of the frame 3 is 0°-40°.

[0038] The distance between the lowest point of the canopy 3 and the ground ranges from 4.5M to 5M.

[0039] Working principle:

[0040] Please see Figures 1 to 3 The ambient wind speed is monitored by wind speed sensor 8. When the ambient wind speed is less than a set threshold, the angle of the sunlight is monitored by light sensor. Based on the monitored angle of the sunlight, the angle of the canopy 3 is adjusted using existing methods.

[0041] When the ambient wind speed exceeds the set threshold, the canopy 3 is adjusted to a horizontal position to enhance wind resistance, effectively reduce wind load, prevent damage to the support structure, and improve the safety and reliability of the system under severe weather conditions.

[0042] During adjustment, the locking telescopic support rod 6 is released, the drive motor 65 drives the gear 64 to rotate, causing the locking collar to rotate and move towards the support rod 62, unlocking the locking notch, so that the extension rod 61 can extend or retract with the electric telescopic rod. When the electric telescopic rod extends or retracts, it causes the canopy 3 to rotate around the pivot connected to the column 1 to adjust the angle. At the same time, the locking telescopic support rod 6 extends or retracts with the electric telescopic rod, and the canopy 3 causes the sliding arm of the potentiometer to rotate, so that the position of the sliding arm on the resistive element of the potentiometer changes, thereby changing the voltage or resistance value output by the potentiometer. The actual position of the canopy 3 is obtained based on the voltage or resistance value output by the potentiometer. The position sensor 5 of the potentiometer feeds back the actual position signal of the canopy 3 to the control terminal to realize closed-loop control and improve the angle adjustment accuracy of the canopy 3.

[0043] After adjustment, the locking telescopic support rod 6 is tightened and locked. The drive motor 65 drives the gear 64 to rotate, which drives the locking collar to rotate and move towards the extension rod 61, tightening the locking notch. This causes the internal thread of the support rod 62 and the external thread of the extension rod 61 to generate friction force for support, thereby locking the locking telescopic support rod 6 and achieving auxiliary stable support. This effectively improves wind resistance and windproof capability, and the structure is stable and the support is firm.

[0044] The energy storage electromechanical control box 7 stores the electrical energy converted by the photovoltaic module 2 and controls the support structure. The support structure is controlled by the energy storage electromechanical control box 7 to achieve energy self-sufficiency and intelligent management. The angle adjustment range of the canopy 3 is 0°-40°, and the lowest end of the canopy 3 is 4.5M-5M above the ground. This ensures sufficient light reception area without affecting the use of ground space. It is particularly suitable for applications such as agricultural photovoltaic integration and carport photovoltaic, achieving wide applicability and strong practicality.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
