[0037] like Figure 1 As shown, it is a flat single-axis photovoltaic tracking bracket shown in the present invention, which is used to install photovoltaic panels and control the direction of the photovoltaic panels.

[0038] like Figure 1 to Figure 2 As shown, the flat single-axis photovoltaic tracking bracket includes: a tracking mechanism 100 and a mounting mechanism 200, wherein the tracking mechanism 100 is used to control the orientation of the mounting mechanism 200, and the number of the mounting mechanisms 200 is multiple, each mounting mechanism 200 is used to install a photovoltaic panel and provide the photovoltaic panel with anti-torsion deformation and anti-pulling capabilities to cope with strong winds, so as to avoid damage to the photovoltaic panel, thereby achieving the purpose of improving the wind resistance of the flat single-axis photovoltaic tracking bracket.

[0039] Below, combined Figures 1 to 8 , the above-mentioned flat single-axis photovoltaic tracking bracket is further explained.

[0040] like Figure 1As shown, the tracking mechanism 100 includes a side frame 101, a steering plate 102 and a driving member 103. There are two side frames 101, and the two side frames 101 are respectively arranged on both sides of the steering plate 102 and are rotatably connected to the steering plate 102. The steering plate 102 is connected to the mounting mechanism 200. The driving member 103 is a motor and is installed on one of the side frames 101. It is used to drive the steering plate 102 to rotate, so as to control the direction of the mounting mechanism 200 on the steering plate 102, thereby realizing the direction control of the mounting mechanism 200.

[0041] like Figure 2 As shown, the mounting mechanism 200 includes a fixing seat 10, a correction member 20, a support frame 30 and a limit assembly 40. The fixing seat 10 is mounted on the steering plate 102 of the tracking mechanism 100 and has a direction axis perpendicular to the rotation direction of the steering plate 102. The correction member 20 connects the fixing seat 10 and the support frame 30 and is used to provide a force for the support frame 30 to be on the direction axis. The support frame 30 is used to install the photovoltaic panel. The limit assembly 40 is mounted on the steering plate 102 of the tracking mechanism 100 and is connected to the support frame 30. The support frame 30 is connected with the steering plate 102. When strong wind blows the photovoltaic panel on the support frame 30, the photovoltaic panel is affected by the strong wind and drives the support frame 30 to twist relative to the fixed seat 10. The correcting member 20 is deformed under the action of external force. Under the protection of the limiting assembly 40, the connection strength between the support frame 30 and the steering plate 102 is increased, thereby preventing the support frame 30 on which the photovoltaic panel is installed from separating from the correcting member 20. When the strong wind stops, the external force is removed, and the correcting member 20 returns to its original state, so that the support frame 30 remains on the direction axis for the photovoltaic panel to receive sunlight.

[0042] like Figure 3 to Figure 4 As shown, the correcting member 20 includes a coil spring 21 and a connecting piece 22, the coil spring 21 is connected to the connecting piece 22, the number of the connecting pieces 22 is two, and the two connecting pieces 22 are respectively arranged at both ends of the coil spring 21, one connecting piece 22 is connected to the fixing seat 10, and the other connecting piece 22 is connected to the support frame 30. Specifically, the connecting piece 22 can be connected to the coil spring 21 by welding, and a through hole is opened on each connecting piece 22 for bolts to penetrate the through hole and connect with the fixing seat 10 or the support frame 30, so as to realize the correcting member 20 and the fixing seat 10 or the support frame 30. 0 connection, wherein the coil spring 21 has the function of absorbing vibration and impact energy. When the support frame 30 is subjected to external force, the ductility of the coil spring 21 can effectively change the posture of the support frame 30. The elastic deformation of the coil spring 21 when loaded can effectively convert mechanical work or kinetic energy into deformation energy, thereby playing a role in absorbing vibration and impact energy. When the external force on the support frame 30 is removed, the reset function of the coil spring 21 is used to drive the connecting piece 22 and the support frame 30 connected to the connecting piece 22 to return to their original state, thereby controlling the support frame 30 to be oriented toward the axis.

[0043] It should be noted that the elastic force of the coil spring 21 is positively correlated with the force that maintains the support frame 30 on the direction axis, that is, the greater the elastic force, the stronger the force that maintains the support frame 30 on the direction axis. It can be understood that if the force that maintains the support frame 30 on the direction axis is greater, when strong winds come, the photovoltaic panels on the support frame 30 have to withstand greater wind force, thereby increasing the risk of the photovoltaic panels detaching from the support frame 30. If the force that maintains the support frame 30 on the direction axis is smaller, it is difficult for the coil spring 21 to maintain the support frame 30 on the direction axis, making it difficult for the tracking mechanism 100 to control the direction of the photovoltaic panel. Therefore, the control of the elastic force of the coil spring 21 is a problem that needs to be solved.

[0044] like Figures 5 and 6 As shown, the fixing seat 10 includes a connecting member 11, a guide member 12 and an adjusting member 13. The connecting member 11 is connected to the connecting piece 22 of the deviation correcting member 20. The guide member 12 is installed on the steering plate 102 of the tracking mechanism 100 and is slidably connected to the connecting member 11. The adjusting member 13 is installed on the mounting member and drives the connecting member 11 to approach or move away from the support frame 30. The adjusting member 13 is a stud and is threadedly connected to the guide member 12. The adjusting member 13 is rotated according to a predetermined torque using a torque wrench to control the adjusting member 13 to push the connecting member 11. Slide along the guide member 12, and make the connecting member 11 jointly squeeze the coil spring 21 with the cooperation of the limit assembly 40. By controlling the adjusting member 13 with a predetermined torque, the connecting member 11 is pushed to squeeze the coil spring 21, so that the elongated (or shortened) length of the coil spring 21 can be effectively controlled, thereby more accurately controlling the elastic force of the coil spring 21, thereby achieving the purpose of effectively controlling the elastic force provided by the coil spring 21 to effectively maintain the support frame 30 on the direction axis, and effectively reducing the risk of the photovoltaic panel detaching from the support frame 30.

[0045] Furthermore, in order to improve the restoration accuracy of the deviation-correcting member 20, as Figure 5 As shown, the connecting member 11 includes a first plug-in portion 111, a limiting portion 112 and a sliding rod 113. The first plug-in portion 111 is embedded in the coil spring 21 of the correcting member 20 to increase the connection stability between the connecting member 11 and the correcting member 20. The limiting portion 112 is connected to the connecting piece 22 of the correcting member 20. The sliding rod 113 is slidably connected to the guide member 12. The guide member 12 is provided with a guide groove 121 and an adjustment groove 122 connected to the guide groove 121. The guide groove 121 is a waist-shaped groove and is slidably connected to the sliding rod 113. The adjustment groove 122 is threadedly connected to the adjustment member 13. The guide groove 121 is helpful for controlling the displacement accuracy of the connecting member 11, thereby preventing the connecting member 11 from being twisted due to the influence of external force, so that the support frame 30 can be restored to its original state on the direction axis through the correcting member 20 and the connecting member 11 after twisting, so as to achieve the purpose of improving the restoration accuracy of the correcting member 20.

[0046] In order to improve the installation convenience of photovoltaic panels, Figure 3 and 7 As shown, the support frame 30 includes a support rod 31, an adapter block 32 and a mounting frame 33. The support rod 31 is penetrated by a limit group protective cover 41 and is connected to the adapter block 32. The adapter block 32 is connected to the mounting frame 33. The connecting piece 22 of the correcting member 20 and the limit group protective cover 41 are both connected to the support rod 31. When installing the support frame 30, first control the support rod 31 to connect with the correcting member 20 and the limit assembly 40, then install the adapter block 32 at the end of the support rod 31 away from the correcting member 20, and finally connect the mounting frame 33 with the photovoltaic panel installed with the adapter block 32 to realize the installation of the support frame 30. The support rod 31 is used to connect the correcting member 20 and the limit assembly 40, and then the adapter block 32 and the mounting frame 33 are installed. This is conducive to improving the connection between the correcting member 20 and the limit assembly 40 and the support frame 30 through a split connection method, and installing the photovoltaic panel independently, so as to achieve the purpose of improving the installation convenience of the photovoltaic panel.

[0047] Specifically, Figure 7 As shown, the support rod 31 includes a second insert portion 311, an adapter ring 312 and a connecting column 313. The second insert portion 311 is embedded in the coil spring 21 of the correcting member 20 to increase the connection stability between the support rod 31 and the correcting member 20. One end of the adapter ring 312 is connected to the connecting piece 22 of the correcting member 20, and the other end of the adapter ring 312 is connected to the limit assembly 40 to facilitate the connection of the support rod 31.

[0048] like Figure 3 and Figure 8 As shown, the limit assembly 40 includes a protective cover 42 and a protective cover 41. The protective cover 42 is connected to the steering plate 102 of the tracking mechanism 100. The protective cover 42 is provided with a protective cavity 421 and a movable hole 422 connected to the protective cavity 421. The protective cover 41 is provided for the connecting column 313 of the support frame 30 to pass through and is connected to the adapter ring 312. The protective cover 41 closes the movable hole 422. The deviation correction member 20 is arranged in the protective cavity 421 and is used to provide a thrust for the protective cover 41 to contact the inner wall of the protective cavity 421. The protective cover 41 has a spherical surface 411, and the protective cavity 421 has a spherical surface 411. The arc surface 423 in contact with the steering plate 102 is provided with the protective cover 42 and the protective cover 41, and the protective cover 42 cooperates with the protective cover 41 to prevent the support frame 30 connected to the protective cover 41 from being separated from the protective cover 42 connected to the steering plate 102. At the same time, the protective cover 42 can also effectively protect the deviation-correcting member 20 in the protection cavity 421 to prevent the deviation-correcting member 20 from being damaged by the outside. In addition, the movable hole 422 restricts the support rod 31 to control the range of movement of the support frame 30, and prevents the support frame 30 from hitting the steering plate 102, so as to reduce the damage to the support frame 30.

[0049] Furthermore, if Figure 3 As shown, the limit assembly 40 also includes a dust cover 43, which is connected to the support frame 30 and forms a dustproof space 431 connected to the movable hole 422 with the protective cover 42. The dust cover 43 can effectively prevent dust or stones from entering the protective cavity 421 through the movable hole 422, so as to increase the service life of the correction component 20.

[0050] like Figure 3 As shown, when the flat single-axis photovoltaic tracking bracket shown in the present invention is in operation: the direction of the steering plate 102 is controlled by the driving member 103 of the tracking mechanism 100 to change the direction of the mounting mechanism 200 installed on the steering plate 102. When strong wind applies force to the mounting mechanism 200, the support frame 30 drives the protective cover 41 of the limit assembly 40 and the connecting piece 22 of the correcting member 20 to move through the adapter ring 312 of the support rod 31. The coil spring 21 of the correcting member 20 deforms under the action of the force, absorbs the kinetic energy of the support frame 30, and converts it into the potential energy (potential energy) of the coil spring 21, thereby alleviating the impact of the force of the strong wind on the mounting mechanism 200 on the support frame 30, so as to reduce the damage caused by the force of the strong wind to the support frame 30 and the photovoltaic panel on the support frame 30. With the cooperation of the protective cover 42 and the protective cover 41, the support frame 30 connected to the protective cover 41 is prevented from being separated from the protective cover 42 connected to the steering plate 102, and the protective cover 42 effectively protects the correcting member 20 in the protective cavity 421 to prevent dust or stones swept by strong winds from damaging the coil spring 21. At the same time, under the restriction of the movable hole 422 on the support rod 31, the movable range of the support frame 30 is effectively controlled to prevent the support frame 30 from hitting the steering plate 102 and being damaged during the activity. When the strong wind stops, with the support of the connecting piece 11 of the fixing seat 10, the external force stored in the coil spring 21 is released, and the twisted coil spring 21 returns to its original state, driving the support frame 30 to be on the facing axis again, so that the photovoltaic panel continues to face the sun after the strong wind to maintain the power generation efficiency.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
