Description

Technical Field

[0002] The angle adjustment of the photovoltaic panel bracket can help solve the problems of reflection loss and temperature rise of photovoltaic modules. Reflection loss is caused by the fact that when sunlight hits the surface of the photovoltaic module at a non-vertical angle, part of the light is reflected and cannot be absorbed and utilized by the photovoltaic module. The temperature rise will cause the performance of the photovoltaic module to decline, which in turn affects the power generation efficiency. By adjusting the angle, these power losses can be reduced and the overall performance of the photovoltaic power generation system can be improved.

Among them, the base 1 is used to support the entire device on the ground, and the fixed frame 3 is used to realize the snap-on installation of the photovoltaic panel. The support frame 2 is provided on the base 1 through a horizontal rotation assembly, and the horizontal rotation assembly is used to drive the support frame to rotate horizontally. The fixed frame 3 is provided on the support frame 2 through a hinge assembly. A tilt adjustment assembly for adjusting the tilt angle of the photovoltaic panel is provided between the fixed frame 3 and the support frame 2. The controller 4 is provided on the support frame to control the operation of the tilt adjustment assembly, thereby realizing the angle adjustment of the fixed frame.

[0022] The specific structure of the horizontal rotation assembly includes a fixed plate 5 arranged on a base 1, and a rotating rod 6 is arranged on the fixed plate 5 through a horizontal rotation driving assembly. The support frame is arranged on the upper end of the rotating rod. Preferably, the rotating rod is arranged at a relatively small height and a relatively large diameter, and the rotating rod is arranged in the middle of the ground of the support frame.

[0023] The horizontal rotation drive assembly includes a worm wheel 7, and a mounting groove 5a for mounting the horizontal rotation drive assembly is provided in the fixed plate 5. The worm wheel 7 is rotatably provided in the mounting groove 5a through a support shaft 8. A worm 9 for cooperating with the worm wheel 7 is rotatably provided in the mounting groove 5a, and a rotating handle 10 for facilitating the rotation of the worm 9 is provided after one end of the worm 9 passes through the mounting groove 5a. The lower end of the rotating rod 6 is fixed on the worm wheel 7. When the worm is rotated, the rotation of the turbine can be realized, thereby realizing the rotation of the support frame.

[0024] Preferably, the fixed plate and the rotating rod are provided with scales and marks for judging the rotation angle of the rotating rod. Of course, a motor for driving the worm to rotate can also be provided so that the worm can be electrically rotated. Other rotating structures such as bevel gears can also be provided.

[0025] The specific structure of the tilt adjustment assembly includes two groups of tilt adjusters arranged on the left and right sides of the hinge assembly, each group of tilt adjusters is provided with at least one, and both ends of the tilt adjuster are hinged on the corresponding parts. The setting of the two groups of tilt adjusters is convenient for supporting and facilitating the tilt adjustment of the fixed frame.

[0026] The inclinometer includes an inclinometer seat 11 hingedly arranged on the support frame 2, an inclinometer tube 12 is arranged on the inclinometer seat 11, a telescopic rod 13 is slidably arranged in the inclinometer tube 12, and a rotating seat 14 is arranged on one end of the telescopic rod 13 extending out of the inclinometer tube 12. At the same time, an inclinometer driving component for realizing the telescopic rod 13 to be telescoped in the inclinometer tube 12 is arranged on the inclinometer seat 11, and a holding component for keeping the telescopic rod 13 in a telescopic stable state is arranged in the inclinometer tube 12.

[0027] The inclination drive assembly includes an inclination drive motor 15 arranged on the inclination adjustment seat 11, and a rotating nut 17 is arranged at the output end of the inclination drive motor 15 through a transmission assembly 16, and a telescopic screw 18 is threaded on the rotating nut 17, and one end of the telescopic screw 18 extends into the inclination adjustment tube 12. When the inclination drive motor rotates, the transmission assembly, the rotating nut and the telescopic screw can cooperate to realize the telescopic movement of one end of the telescopic screw in the inclination adjustment tube, thereby realizing the extension and retraction of the telescopic rod.

[0028] The holding assembly includes a first piston 19 and a second piston 20 arranged at intervals in the inclinometer cylinder 12, wherein the first piston 19 is arranged at the moving end of the inclinometer drive assembly, that is, the first piston is arranged on one end of the telescopic screw located in the inclinometer cylinder, and the second piston 20 is arranged on one end of the telescopic rod 13 located in the inclinometer cylinder 12. In order to push the telescopic rod to move when the telescopic screw is extended, a push spring 21 is arranged between the first piston 19 and the second piston 20. In order to avoid the problem of fracture and damage at the rigid connection between the fixed frame and the telescopic rod, a support spring 22 located in the inclinometer cylinder 12 is arranged on the outer sleeve of the telescopic rod 13.

[0029] Preferably, a magnetic detector 23 is provided on the first piston 19, and a detection magnet 24 for detection by the magnetic detector 23 is provided on the second piston 20. When the photovoltaic panel changes the angle of the fixed frame under the influence of the external environment, the other end of the telescopic rod will move in the inclination adjustment cylinder, that is, push the second piston to move in the inclination adjustment cylinder. At this time, the push spring has a buffering effect and changes the signal detected by the magnetic detector. That is, the change in the distance between the first piston and the second piston can be detected by the magnetic detector and the detection magnet. According to the detected signal, the inclination adjustment motor is driven to work, and then the movement of the telescopic rod is balanced by the telescopic screw to keep the photovoltaic panel within the optimal angle range.

[0031] Preferably, the support frame is configured as a rectangular frame, and the support frame and the fixing frame are made of a lightweight material with a certain hardness, such as an aluminum alloy. Specifically, the support frame and the fixing frame can be welded from a plurality of square tubes.

[0032] In order to ensure the fixation between the fixed plate and the base, a clamping flange is provided at the lower end of the fixed plate, and the base includes a fixed portion at the bottom and a clamping portion at the top that can be pressed on the clamping flange. In order to facilitate the installation of the horizontal rotation drive assembly, the fixed plate is composed of two parts, the lower part is fixedly arranged on the fixed plate, and the installation groove is also arranged in the lower part, and the upper part is a fixed cover that can cover the installation groove. Furthermore, the base can be cast by concrete, in which case the lower part of the fixed plate is pre-buried in the base.

[0033] The controller adopts a structure with wireless communication function, information processing function and information transmission function in the prior art, so that the controller can realize signal transmission with the photovoltaic station, and can judge whether the angle of the photovoltaic panel needs to be adjusted according to the signal transmitted by the magnetic detector, and synchronously send corresponding instructions to the tilt adjustment component to make the tilt adjustment component work, thereby ensuring that the photovoltaic panel can be at the best angle. Preferably, a battery and an operation display screen with interactive function are set in the controller.
