Description

Technical Field

[0001] The invention relates to the field of photovoltaic equipment, and in particular to a device for adjusting the inclination angle of a solar panel. Background Art

[0002] The power generation efficiency of traditional fixed solar panels is significantly affected by the installation inclination during use. Currently, most photovoltaic systems use a fixed installation angle, which has a simple structure and low cost. However, in actual use, it is difficult to adjust the inclination of solar panels according to changes in the sun's position and climate factors, resulting in inefficient energy capture and potential economic losses.

[0003] A Chinese patent (publication number CN115250092A) discloses a solar power generation device and method that is easy to adjust the direction. A turntable driven by a rotary drive unit is provided, and the rear end of the support platform is hinged to the outer side of the turntable so that the support platform can rotate with the turntable and can swing freely relative to the turntable in pitch. A curved guide rail with a high middle and low ends is provided at the front end of the base. The front end of the support platform slides with the curved guide rail through a slide seat to achieve simultaneous adjustment of the circumferential angle and pitch angle of the solar panel as the sun moves. It is consistent with the movement law that the axial angle and pitch angle change simultaneously during the sun's rise and fall, which improves the efficiency of solar energy receiving sunlight. However, the adjustment of the pitch angle and the axial angle is a linkage structure, and the strength and stability are poor. When the solar power generation device is used outdoors, it is easy to be affected by strong external airflow and cause uncontrollable deviation, causing damage; and when the pitch angle and the axial angle are a linkage structure, the adjustment range of the axial angle is limited. When dealing with the external airflow, it is difficult to put the solar panel in a good state of resisting wind force, resulting in poor weather resistance. Summary of the invention

[0004] The purpose of the present invention is to provide a solar panel inclination direction adjustment device in view of the defects of the prior art. The solar panel can adjust its inclination relative to the support frame through an inclination adjustment mechanism. The support frame is connected to the base through the direction adjustment mechanism to adjust the direction of the solar panel, thereby ensuring the efficiency of the solar panel in receiving sunlight and measuring the wind speed and direction. When the wind speed exceeds the set value, the inclination and direction of the solar panel can be changed to make it conform to the wind direction to reduce overturning and damage caused by airflow, thereby improving its stability and ensuring safety.

The grooves in the middle of the turntable 14 and the cover plate 10 contain balls, and the two can rotate relative to each other. The top of the turntable 14 is welded to two aluminum profiles VII 18.

[0045] In this embodiment, Figure 1 As shown, the solar panel is rectangular, and the light sensors 34 are installed at the four sides of the rectangular solar panel. Specifically, the four light sensors 34 are installed on the four sides of the silicon board 35 in a cross shape.

[0046] The wind speed sensor 31 is fixed to the upper left side of the aluminum plate 25 by means of threaded connection, and the installation position is higher than the highest point of the solar panel to avoid being blocked by the solar panel.

[0047] The wind direction sensor 30 is fixed to the upper right side of the aluminum plate 25 by means of a threaded connection, and the installation position is higher than the highest point of the solar panel to avoid being blocked by the solar panel.

[0049] In this embodiment, the operation process of the solar panel tilt angle adjustment device is as follows:

[0050] After the solar panel tilt angle adjustment device is put into use, the four light sensors 34 located at the four corners of the silicon panel will detect the light changes in the environment in real time, and transmit the detected information to the controller in the form of analog signals. In this embodiment, the controller is an Arduino mega control board; wherein, the light sensors 34 located on the upper and lower sides of the silicon panel 35 are used to detect the longitudinal light changes of the sunlight, and the light sensors 34 located on the left and right sides of the silicon panel 35 are used to detect the lateral light changes of the sunlight; the wind speed sensor 31 and the wind direction sensor 30 are used in conjunction to detect the wind speed and wind direction changes in the environment in real time, and transmit the detected information to the Arduino mega control board in the form of analog signals; the Arduino mega control board will comprehensively analyze the most suitable orientation and installation tilt angle of the solar panel under the current conditions according to the signals fed back by each sensor, and then send a control signal to the motor driver. In this embodiment, the motor driver is TB6600. The operation process of the transmission mechanism located inside the base, the transmission mechanism located above the base and the solar panel installation tilt angle adjustment mechanism are described below.

[0051] The operation process of the orientation adjustment mechanism:

[0052] After receiving the control signal from the Arduino mega control board, the motor driver TB6600 drives the stepper motor I 4 to rotate and drives the synchronous pulley I 9 to rotate synchronously. The synchronous pulley I 9 transmits power to the transmission shaft 5 through the synchronous belt I 8. The transmission shaft 5 drives the turntable 14 to rotate synchronously. The turntable 14 drives the two aluminum profiles VII 18 welded thereto to rotate synchronously, thereby driving the transmission mechanism, the solar panel support frame, the solar panel installation inclination adjustment mechanism, the solar panel, the wind speed sensor 31, the wind direction sensor 30, and the light sensor 34 located above the base to rotate synchronously, thereby realizing the function of adjusting the direction of the solar panel.

[0053] After receiving the control signal from the Arduino mega control board, the motor driver TB6600 drives the stepper motor II 23 to rotate and drives the synchronous pulley II 15 to rotate synchronously. The synchronous pulley II 15 transmits power to the synchronous pulley III 20 through the synchronous belt II 19.

[0054] The operation process of the tilt adjustment mechanism:

[0055] After receiving the power from the synchronous pulley II 15, the synchronous pulley III 20 drives the screw 26 to rotate synchronously around the center of the screw support seat 22, and the screw 26 drives the screw nut 24 matched with it through the thread to move up and down, and the screw nut 24 drives the first connecting rod 27 connected thereto to swing up and down, and the first connecting rod 27 drives the second connecting rod 28 to swing up and down. A limit is provided at the connection between the first connecting rod 27 and the second connecting rod 28, so the position of the connection between the first connecting rod 27 and the second connecting rod 28 is locked, ensuring that the power from the screw nut 24 is stably transmitted to the solar panel, and the second connecting rod 28 drives the solar panel and the light sensor 34 to rotate around the two connecting hinges 33 fixed on the aluminum profile IX 32 and the aluminum profile III 11 through the connecting rod connecting support 29 fixed on the aluminum profile III 11, thereby realizing the function of adjusting the installation inclination angle of the solar panel.

[0056] The above process runs continuously, thereby ensuring that the solar panel tilt angle direction adjustment device can continue to function.
