Solar photovoltaic power generation meets people's needs for daily life and production. As a clean energy source, solar energy is one of the energy sources that people cannot do without today. Currently, photovoltaic panel modules are usually installed on photovoltaic brackets, which can be adjusted according to the angle between sunlight and photovoltaic panels. The existing patent authorization announcement number CN217741638U discloses an automatic tracking and adjustment photovoltaic power station support. The lower part of the support column is equipped with a transmission gear, and a motor drives a power gear, which in turn drives the support column to rotate. The power gear and the transmission gear can be directly meshed or driven by a chain to achieve the circumferential angle adjustment of the photovoltaic panel. The bottom of the support frame is hinged to the top of the support column, and the vertical tilt angle of the photovoltaic panel can be adjusted by pushing and pulling an electric push-pull rod. Since photovoltaic panels are generally installed outdoors, the transmission gears and power gears in the aforementioned patent are exposed without corresponding protective measures. After long-term use, the overall wear is significant, which is not conducive to later maintenance and reduces the service life. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: an automatic photovoltaic tracking bracket, including a support base 1 and a photovoltaic panel 2. A rotating component 3 is fixedly installed on the top of the support base 1, and a mounting frame 4 is provided on the top of the rotating component 3. The photovoltaic panel 2 is disposed outside the mounting frame 4. The rotating component 3 includes a protective shell 31, a rotating shaft 32, and a protective cover 33. The protective shell 31 is fixedly installed on the top of the support base 1, and the protective cover 33 is fixedly installed on the top of the protective shell 31. The rotating shaft 32 is rotatably installed inside the protective shell 31. A drive gear 34 is rotatably installed at the rear of the interior of the protective shell 31. A driven gear 35 that meshes with the drive gear 34 is fixedly installed outside the rotating shaft 32. A drive gear 35 that meshes with the protective cover 33 is fixedly installed outside the rotating shaft 32. The protective cover 33 is equipped with a sealed bearing 37. A motor 38 connected to the drive gear 34 is fixedly installed on the top of the protective cover 33. The interior of the protective shell 31 is filled with lubricating oil. An oil change port 39 is opened at the rear of the bottom of the protective shell 31. A sealing plug 310 is installed inside the oil change port 39. The ball bearing 36 is placed at the bottom of the rotating shaft 32 and contacts the bottom of the inner wall of the protective shell 31. The sealed bearing 37 is installed at the joint between the rotating shaft 32 and the protective cover 33, which can reduce the friction between the rotating shaft 32 and the protective shell 31 and the protective cover 33. The protective shell 31 and the protective cover 33 cover the drive gear 34 and the driven gear 35, which plays a protective role and prevents the influence of the external environment. The lubricating oil injected into the protective shell 31 further reduces wear and extends service life.

[0016] Multiple balls 36 are movably mounted on the bottom of the rotating shaft 32. The balls 36 are arranged in a ring at equal intervals at the bottom of the rotating shaft 32. The balls 36 can convert the sliding friction between the bottom of the rotating shaft 32 and the bottom of the inner wall of the protective shell 31 into rolling friction, which effectively reduces the resistance during rotation, making the rotation of the rotating shaft 32 smoother and more stable. At the same time, it further disperses the pressure of the rotating shaft 32 on the bottom of the protective shell 31, avoids excessive local wear, and thus improves the operational stability and durability of the entire transmission structure.

[0017] The protective cover 33 is fixedly connected to the top of the protective shell 31 by bolts. A sealing ring is provided between the protective shell 31 and the protective cover 33. It is made of aging-resistant rubber material and can fit tightly to the mating surface of the protective shell 31 and the protective cover 33. It effectively blocks external dust, moisture and impurities from entering the interior of the protective shell 31, avoids the lubricating oil from being contaminated and reducing the lubrication effect, and prevents internal lubricating oil leakage, ensuring that the interior of the protective shell 31 always maintains a good lubrication environment.

[0018] The output shaft of the motor 38 is connected to the drive gear 34 via a key for transmission. The drive gear 34 meshes with the driven gear 35, which is fixedly sleeved on the outer wall of the rotating shaft 32. When the motor 38 starts, its output shaft drives the drive gear 34 to rotate. The drive gear 34 drives the driven gear 35 to rotate synchronously through tooth meshing, thereby driving the rotating shaft 32 to rotate within the protective shell 31. This achieves the angle adjustment function of the photovoltaic bracket. By reasonably designing the tooth ratio of the drive gear 34 and the driven gear 35, the speed and torque of the rotating shaft 32 can be adjusted according to actual needs, making the tracking adjustment of the photovoltaic bracket more precise and efficient.

[0019] Please see Figure 1 , Figure 4 and Figure 5 The mounting frame 4 includes a support frame 41, which is fixedly mounted on the top of the rotating shaft 32. An adjusting frame 42 is movably hinged to the front of the top of the support frame 41. A lug 43 is fixedly connected to the rear of the bottom of the support frame 41. A lug 44 corresponding to lug 43 is fixedly connected to the bottom of the adjusting frame 42. An electric push rod 45 is movably hinged between lug 43 and lug 44. In windy weather, the electric push rod 45 can be retracted. When the electric push rod 45 retracts, it will pull the adjusting frame 42 connected through lug 44, causing it to rotate around the connection point with the support frame 41, thereby driving the photovoltaic panel 2 to rotate. The adjusting frame 42 drives the photovoltaic panel 2 to fit against the top of the support frame 41, so that the photovoltaic panel 2 is placed horizontally, improving wind resistance.

[0020] The top of the adjustment frame 42 is provided with an installation groove corresponding to the photovoltaic panel 2. The photovoltaic panel 2 is movably installed inside the installation groove. The inner sidewall of the installation groove is symmetrically provided with elastic buffer pads, which can reduce the damage caused by vibration to the photovoltaic panel 2 during installation and use. The two ends of the installation groove are also provided with detachable limit baffles. The limit baffles are fixedly connected to the adjustment frame 42 by bolts, which can limit the position of the photovoltaic panel 2.

[0021] The hinge between the adjustment frame 42 and the support frame 41 is connected by a bearing. The outer ring of the bearing is connected to the support frame 41, and the inner ring is connected to the adjustment frame 42. This reduces the frictional resistance when the adjustment frame 42 rotates, ensuring that the photovoltaic panel 2 is more stable and smooth during the angle adjustment process. A sealing protective sleeve is fitted on the outside of the bearing to effectively prevent impurities from entering.

[0022] Working principle: During use, the photovoltaic panel 2 is installed on the ground by the support base 1 to provide support, and the photovoltaic panel 2 is installed on the adjustment frame 42. The light sensor set on the mounting frame 4 detects the change in solar displacement and transmits the signal to the external control device. The control device adopts PLC control and controls and adjusts the angle of the photovoltaic panel 2 according to the signal data. The motor 38 drives the drive gear 34 inside the protective shell 31 to rotate. The drive gear 34 drives the driven gear 35 meshing with it to rotate. The rotation of the driven gear 35 drives the rotating shaft 32 to rotate, which in turn drives the mounting frame 4 and photovoltaic panel 2 above the rotating shaft 32 to rotate laterally to follow the sun's position. At the same time, the electric push rod 45 can be controlled to push the adjustment frame 42 to rotate along its hinge with the support frame 41, adjusting the pitch angle of the photovoltaic panel 2 so that it faces the sun to the maximum extent. When encountering strong winds, the electric push rod 45 can be shortened. When the electric push rod 45 is shortened, it pulls the adjustment frame 42 connected by the lug 44, causing it to rotate along its connection with the support frame 41, driving the photovoltaic panel 2 to rotate. The adjustment frame 42 drives the photovoltaic panel 2 to stick to the top of the support frame 41, so that the photovoltaic panel 2 is placed horizontally, thereby effectively improving the wind resistance. The ball bearings 36 at the bottom of the rotating shaft 32 contact the bottom of the inner wall of the protective shell 31. When the rotating shaft 32 rotates, the ball bearings 36 roll. Combined with the sealing bearing 37 installed at the joint between the rotating shaft 32 and the protective cover 33, the friction between the rotating shaft 32 and the protective shell 31 and the protective cover 33 can be reduced. The protective shell 31 and the protective cover 33 cover the outside of the driving gear 34 and the driven gear 35, providing protection and avoiding the influence of the external environment. At the same time, the protective shell 31 is filled with lubricating oil, and the components inside are covered with an oil film, which further reduces wear and improves service life. The lubricating oil in the protective shell 31 can be discharged through the oil change port 39 by unscrewing the sealing plug 310, and the protective shell 31 can be replaced. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
