Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel mounting brackets, and in particular to a solar photovoltaic panel auxiliary mounting bracket capable of tracking sunlight. Background Art

[0002] As the global demand for clean energy continues to grow, solar photovoltaic power generation has been widely used as a sustainable energy solution. The auxiliary mounting bracket of solar photovoltaic panels plays a vital role in solar power generation systems. It not only provides a stable support structure for photovoltaic panels, ensuring that photovoltaic panels can be safely installed in different terrains and environments, but also has intelligent functions. By receiving satellite information from the weather station, this auxiliary mounting bracket can automatically track the sun, so that the photovoltaic panels always maintain the best lighting angle and maximize the reception of solar energy, thereby achieving efficient photovoltaic panel power generation. This automatic tracking function can adjust the angle and direction of the photovoltaic panel in real time according to the changes in the position of the sun. Whether in the morning, noon or evening, it can ensure that the photovoltaic panel is perpendicular to the sunlight, significantly improve the conversion efficiency of solar energy, and make an important contribution to the sustainable supply of energy. Moreover, in areas such as the Gobi Desert, since there are no shading objects, sunlight can shine on the photovoltaic panel without hindrance, making the utilization rate of solar energy extremely high, further highlighting the importance of efficient auxiliary mounting brackets.

[0003] However, when solar photovoltaic panels are installed in special environments such as the Gobi Desert, they face many challenges. The Gobi Desert has harsh climatic conditions, and extreme weather such as strong winds and sandstorms often occur. Strong winds may cause tremendous pressure on photovoltaic panels and brackets, causing the brackets to deform or even break. Photovoltaic panels may also be damaged by the impact of the wind. The sand and dust will not only cover the surface of the photovoltaic panels under strong winds, reducing the photovoltaic panels' efficiency in absorbing sunlight, but the abrasive effect of the sand and dust will also affect the service life of the photovoltaic panels. In such a harsh environment, how to protect solar photovoltaic panels and auxiliary mounting brackets so that they can operate stably and efficiently has become an urgent problem to be solved. Based on the above viewpoints, the present invention proposes a solar photovoltaic panel auxiliary mounting bracket with the function of tracking sunlight. Summary of the invention

[0014] The present invention has the following technical points and beneficial effects:

[0015] 1.

Part of the wind force is decomposed into a direction parallel to the panel surface, reducing the pressure in the vertical direction.

[0017] 3. By detaching the front end of the spring shaft from the upper and lower side walls of the outer protective bracket and no longer connecting to the outer protective bracket, the photovoltaic panel mounting bracket is now connected to the anti-sand and dust assembly only by stretching the steel cable to prevent wind and sand from different directions from continuously hitting the photovoltaic panel. The photovoltaic panel mounting bracket can swing in the storm by stretching the steel cable, and part of the force will be dispersed through the elasticity and swing of the steel cable. By stretching the steel cable, the bracket can be prevented from being damaged due to excessive lateral bending moment. This method can protect the overall structural integrity of the bracket and prevent the bracket from twisting, deformation or breakage due to excessive local force.

[0018] 4. The auxiliary mounting bracket realizes the tilting, closing and disengagement of the photovoltaic panel through mechanical structures such as tensile steel cables, steel cable sliders, spring shafts, lever assemblies and anti-dust assemblies, thereby avoiding damage to electronic components caused by strong magnetic fields in severe weather, so that the auxiliary mounting bracket still has a reliable protective effect in severe environments.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a solar photovoltaic panel auxiliary installation bracket with the function of tracking sunlight, including an installation base 1, a support base 2 fixed on the installation base 1, a support rod 3 installed on the support base 2, and an electric control box 4 suspended on the support rod 3 through a bracket, the electric control box 4 is mainly used to receive climate information transmitted by a meteorological station, which includes data such as the solar light intensity, light angle and wind strength in the area, and a driving component 5 is installed on the upper end surface of the electric control box 4. The driving component 5 includes a driving chassis 51, and the upper end surface of the driving chassis 51 is rotatably connected to an X-axis rotating table 52, and a reducer 54 is installed on the upper side wall of the X-axis rotating table 52, and a Y-axis rotating motor 53 is connected to the input shaft of the reducer 54, and a Y-axis mounting frame 55 is installed on the output shaft of the reducer 54, and a sand and dust prevention component 7 is installed in the Y-axis mounting frame 55.

[0036] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the dust-proof assembly 7 includes a dust-proof shell 71, and dust-proof plates 72 are installed on both side walls of the dust-proof shell 71. A dust induction box 74 is installed on the top of the dust-proof shell 71, and a dust induction groove 75 is opened on the dust induction box 74. A dust exhaust floor 76 is detachably connected to the bottom of the dust-proof shell 71, and a guide plate 77 is connected to the top of the dust exhaust floor 76 through a spring. A dust-proof plate 72 is installed on the rear side wall of the dust-proof shell 71, and an elastic rope 78 is connected to the movable end of the dust-proof plate 72. The other end of the elastic rope 78 is fixedly connected to a driving block 79, and the driving block 79 is slidably connected to the upper end surface of the guide plate 77 through a spring limit, and the two side walls of the driving block 79 are fixedly connected to ear hooks 712. The dustproof plate 72 is rotatably connected to the photovoltaic panel mounting bracket 6, and the photovoltaic panel mounting bracket 6 includes an outer protective bracket 61, and the inner mounting bracket 62 is rotatably connected to the outer protective bracket 61 through a spring hinge. The two side walls of the anti-dust shell 71 are slidably connected to the upper position. The steel cable slider 11, the two steel cable sliders 11 are respectively arranged on the rear sides of the two ear hooks 712, and the outer side walls of the two ear hooks 712 are fixedly connected with tension steel cables 12, and the other ends of the two tension steel cables 12 are fixedly connected to the inner mounting bracket 62, driving the movable end of the electric cylinder 73 to contract, and then pulling the driving block 79 to move backward through the elastic rope 78, and then when the driving block 79 moves backward, the two ear hooks 712 drive the two steel cable sliders 11 to slide backward, and when the steel cable slider 11 moves backward, it will pull the inner mounting bracket 62 to rotate through the tension steel cable 12, and after the inner mounting bracket 62 is tilted, the contact area between the wind and the photovoltaic panel is reduced, and the direction of the wind force is changed. Part of the wind force is decomposed into a direction parallel to the panel surface, reducing the pressure in the vertical direction, and the wind can flow through the surface of the photovoltaic panel more smoothly, thereby greatly reducing wind resistance and avoiding the pressure perpendicular to the panel surface causing the bracket and the photovoltaic panel to bend or even break.

[0037] like Figure 3 and Figure 4 As shown, the driving assembly 5 also includes an X-axis rotating motor 58 installed at the bottom of one side of the driving chassis 51, and a pulley 56 is connected to the output shaft of the X-axis rotating motor 58. A driving belt 57 is sleeved on the bottom of the outer wall of the X-axis rotating platform 52 and the outer wall of the pulley 56. The electric control box 4 is used to receive weather station information and is electrically connected to the Y-axis rotating motor 53, the X-axis rotating motor 58 and the driving electric cylinder 73. The angles and facing directions of the two photovoltaic panel mounting brackets 6 are adjusted by the X-axis rotating motor 58 and the Y-axis rotating motor 53, so that they can rotate synchronously with the sun, thereby realizing high efficiency of photovoltaic work.

[0038] like Figure 3 As shown, elastic seals 63 are fixedly connected to the two inner side walls of the outer protective bracket 61, and the outer protective bracket 61 is sealed by the elastic seals 63, thereby providing conditions for the rotation of the inner mounting bracket 62 while ensuring the sealing condition.

[0039] Embodiment 2, as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, this embodiment provides another implementation method based on the first embodiment. The two side walls of the anti-sand and dust shell 71 are installed with a lever assembly 8 near the front end. The lever assembly 8 includes a lever piece 82. The middle position of the lever piece 82 is pin-connected to the outer wall of the anti-sand and dust shell 71. The top pin of the lever piece 82 is connected to a wedge-shaped slide bar 81. The wedge-shaped slide bar 81 is limitedly slidably connected to the outer wall of the anti-sand and dust shell 71. The bottom pin of the lever piece 82 is connected to a toothed slide bar 83. The toothed slide bar 83 is limitedly slidably connected to the outer wall of the anti-sand and dust shell 71 through a spring. The toothed part of the toothed slide bar 83 is meshed with the tooth pattern of the outer wall of the outer protective bracket 61. The two side walls of the guide plate 77 are fixedly connected with a wedge-shaped plate 711, the bottom of the front side wall of the wedge-shaped slide bar 81 abuts against the rear end of the wedge-shaped slide bar 81, the front inner wall of the dustproof shell 71 is connected to the limiting spring bracket 710 through a spring, the rear end of the limiting spring bracket 710 abuts against the driving block 79, the air outlet position of the dust induction groove 75 corresponds to the rear side of the guide plate 77, the upper side wall of the guide plate 77 is provided with an inclined surface at the rear end, and a fixing mechanism for locking the two outer protective brackets 61 is installed on the front side wall of the outer protective bracket 61, which can be a magnet, a mechanical lock or the like. When a strong wind carries a lot of dust, the airflow entering the dust induction groove 75 is wrapped The dust is carried by a large amount of dust, and after entering the dust-proof housing 71, the dust will accumulate above the driving block 79, and slide down from the upper surface of the driving block 79 and the guide plate 77 and be discharged from the dust-proof housing 71. However, due to the large dust content in the airflow and the high speed of the airflow entering the dust inlet groove 75, the dust discharge speed will be significantly lower than the dust entry speed, which will cause the dust to accumulate above the driving block 79. As the dust on the driving block 79 continues to accumulate, the driving block 79 will be pressed to slide downward, thereby driving the guide plate 77 to slide downward together. When the guide plate 77 slides downward, the wedge plates 711 connected at both sides of the guide plate 77 will push the wedge plates 711 to move downward. The shaped slide bar 81 slides forward, thereby driving the top end of the lever piece 82 to swing forward and the bottom end of the lever piece 82 to swing backward. When the bottom of the lever piece 82 swings backward, the bottom of the lever piece 82 will push the toothed slide bar 83 to slide backward, and then drive the entire photovoltaic panel mounting bracket 6 to rotate inward through the toothed plate part on the front side of the toothed slide bar 83. The two photovoltaic panel mounting brackets 6 are closed after rotation, so that the photovoltaic panels installed inside the two inner mounting brackets 62 are wrapped inside, avoiding damage to the surface of the photovoltaic panels caused by the impact of dust from the front in strong wind weather, thereby protecting the photovoltaic panels and extending the service life of the photovoltaic panels in harsh environments.

[0040] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the two dustproof plates 72 are slidably connected with spring shafts 10 through spring limiters, the front ends of the two spring shafts 10 are clamped on the upper and lower side walls of the outer protective bracket 61, and the side walls of the anti-sand and dust shell 71 are connected with wedge-shaped sliders 9 through springs, and the rear ends of the two spring shafts 10 are abutted against the upper and lower side walls of the wedge-shaped sliders 9. When an extremely harsh environment such as a sandstorm occurs, it exhibits super strong wind force and a huge amount of dust, and the dust flows in the air at an extremely fast speed, which makes it impossible for the dust to be discharged from the guide plate 77 after entering the anti-sand and dust shell 71, and is continuously filled between the drive block 79 and the rear side wall of the anti-sand and dust shell 71 under the drive of the storm, causing the drive block 79 to continuously move forward, and when the drive block 79 moves forward, the two sides of the drive block 79 The side-connected ear hook 712 will push the wedge-shaped slider 9 to move forward, thereby causing the rear end of the spring shaft 10 to expand outward along the outer wall of the wedge-shaped slider 9, and the front end of the spring shaft 10 will detach from the upper and lower side walls of the outer protective bracket 61 and will no longer be connected to the outer protective bracket 61. At this time, the photovoltaic panel mounting bracket 6 is only connected to the anti-sand and dust component 7 by stretching the steel cable 12 to prevent wind and sand from different directions from continuously hitting the photovoltaic panel. The photovoltaic panel mounting bracket 6 can swing in the storm by stretching the steel cable 12, and part of the force will be dispersed through the elasticity and swing of the steel cable. By stretching the steel cable 12, the bracket is prevented from being damaged due to excessive lateral bending moment. This method can protect the overall structural integrity of the bracket and prevent the bracket from twisting, deforming or breaking due to excessive local force.

[0041] Working principle: The electric control box 4 is mainly used to receive the climate information transmitted by the weather station, which includes data such as the solar light intensity, light angle and wind strength in the area. The angles and facing directions of the two photovoltaic panel mounting brackets 6 are adjusted by the X-axis rotating motor 58 and the Y-axis rotating motor 53, so that they can rotate synchronously with the sun, thereby realizing efficient photovoltaic operation. Once it is detected that the wind strength in the area is high, the electric control box 4 will further control the driving electric cylinder 73 to start working, and the active end of the driving electric cylinder 73 will shrink, and then the driving block 79 will be pulled to move backward through the elastic rope 78. Then, while the driving block 79 moves backward, the two ear hooks 712 drive the two steel cable sliders 11 to slide backward. When the steel cable slider 11 moves backward, it will pull the inner mounting bracket 62 to rotate by stretching the steel cable 12. After the inner mounting bracket 62 is tilted, the contact area between the wind and the photovoltaic panel is reduced, and the direction of the wind force is changed. Part of the wind force is decomposed into a direction parallel to the panel surface, reducing the pressure in the vertical direction. The wind can flow through the surface of the photovoltaic panel more smoothly, thereby greatly reducing wind resistance and avoiding the pressure perpendicular to the panel surface causing the bracket and the photovoltaic panel to bend or even break.

[0042] When strong winds carry a lot of dust, the airflow entering the dust inlet groove 75 carries a large amount of dust. After entering the dust-proof housing 71, the dust will accumulate above the drive block 79 and slide down from the upper surface of the drive block 79 and the guide plate 77 and be discharged from the dust-proof housing 71. However, due to the large amount of dust carried in the airflow and the high speed of the airflow entering the dust inlet groove 75, the dust discharge speed will be significantly lower than the dust entry speed, which will cause dust to accumulate above the drive block 79. As the dust on the drive block 79 continues to accumulate, the drive block 79 will be pressed to slide downward, thereby driving the guide plate 77 to slide downward together. When the guide plate 77 slides downward, the positions on both sides of the guide plate 77 The connected wedge plate 711 will push the wedge slide 81 to slide forward, thereby driving the top end of the lever piece 82 to swing forward and the bottom end of the lever piece 82 to swing backward. When the bottom of the lever piece 82 swings backward, the bottom of the lever piece 82 will push the toothed slide 83 to slide backward, thereby driving the entire photovoltaic panel mounting bracket 6 to rotate inward through the toothed plate part on the front side of the toothed slide 83. The two photovoltaic panel mounting brackets 6 are closed after rotation, so that the photovoltaic panels installed inside the two inner mounting brackets 62 are wrapped inside, avoiding damage to the surface of the photovoltaic panels caused by the impact of dust from the front in strong wind weather, thereby protecting the photovoltaic panels and extending the service life of the photovoltaic panels in harsh environments.

[0043] When an extremely severe environment such as a sandstorm occurs, it exhibits extremely strong wind force and carries a huge amount of dust, and the dust flows in the air at an extremely fast speed, so that after the dust enters the anti-sand and dust shell 71, it is not only unable to be discharged from the guide plate 77, but also continuously fills up between the driving block 79 and the rear side wall of the anti-sand and dust shell 71 under the drive of the storm, causing the driving block 79 to continuously move forward. When the driving block 79 moves forward, the ear hooks 712 connected on both sides of the driving block 79 will push the wedge-shaped slider 9 to move forward, thereby causing the rear end of the spring shaft 10 to expand outward along the outer side wall of the wedge-shaped slider 9. The front end of the spring shaft 10 is detached from the upper and lower side walls of the outer protective bracket 61 and is no longer connected to the outer protective bracket 61. At this time, the photovoltaic panel mounting bracket 6 is connected to the anti-dust component 7 only by stretching the steel cable 12 to prevent wind and sand from different directions from continuously hitting the photovoltaic panel. The photovoltaic panel mounting bracket 6 can swing in the storm by stretching the steel cable 12. Part of the force will be dispersed through the elasticity and swing of the steel cable. By stretching the steel cable 12, the bracket can be prevented from being damaged due to excessive lateral bending moment. This method can protect the overall structural integrity of the bracket and prevent the bracket from twisting, deformation or breakage due to excessive local force.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
