Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a supporting device for photovoltaic power generation. Background Art

[0002] Photovoltaic power generation components usually need to be installed on a supporting device. The prior art discloses a variety of supporting devices for photovoltaic power generation, such as the self-tracking photovoltaic power generation component proposed in the Chinese invention patent application with publication number CN117997252A. In the process of tracking the sun under the condition of sunshine all day, the photovoltaic panel must have two tilting states. During the conversion between the two tilting states, the support frame, the slider support and the ball bearing move toward the ground under the action of gravity, so as to cause the support frame and the light-transmitting film to move back and forth and vibrate, so as to shake off the dust and impurities on the light-transmitting film. During the movement of the slider support toward the ground, it will also drive the movement of the sweeping film. The straight section of the sweeping film has a cleaning effect on the surface of the light-transmitting film. At the same time, under the action of the arc section of the sweeping film, the airflow is accelerated during the movement of the sweeping film, so as to disturb the light impurities on the light-transmitting film, further improve the cleaning effect of the light-transmitting film, thereby ensuring the high power generation efficiency of the photovoltaic panel.

[0003] Although the above-mentioned prior art can adjust the angle of the photovoltaic module, its adjustment angle is limited and the photovoltaic module cannot be flipped 180 degrees. When encountering hail and heavy rain, the photovoltaic module is directly subjected to the impact of hail and the erosion of rain and mud, which makes the photovoltaic module easy to be damaged, resulting in a decrease in reliability and power generation efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a photovoltaic power generation support device which can be flipped 180 degrees so that the photovoltaic module faces downward, thereby reducing damage to the photovoltaic module and improving the reliability and power generation efficiency of the photovoltaic module.

On rainy days, rainwater flows downward along the photovoltaic components on the mounting frame and is concentrated in the water storage chamber through the water inlet of the water tank. When it rains heavily and the amount of water flowing into the water storage chamber of the water tank through the water inlet is greater than the amount of water discharged through the drain pipe, the water storage chamber of the water tank is gradually filled, so that the overall weight of the water tank gradually increases and decreases. In this process, the water tank pulls the wheel to rotate through the cable, and the wheel drives the mounting frame to flip 180 degrees through the transmission member, so that the photovoltaic components on the mounting frame face downward, and the metal plate on the back of the photovoltaic faces upward, so that the metal plate protects the photovoltaic panel, avoids hail from hitting the photovoltaic panel, and also avoids rain and mud from scouring the photovoltaic panel, reduces damage to the photovoltaic components, and improves the reliability and power generation efficiency of the photovoltaic components.

[0029] When it is sunny during the day, the elastic force of the torsion component 9 drives the photovoltaic components upward through the rotating shaft 1, preventing the mounting frame 2 from rotating freely on the rack 1. The mounting frame 2 drives the photovoltaic components upward, so that the sunlight shines on the photovoltaic components to generate electricity. On rainy days, rainwater flows downward along the photovoltaic components on the mounting frame 2 and is concentrated into the water storage chamber through the water inlet of the water tank 7. When it rains heavily, the amount of water flowing into the water storage chamber of the water tank 7 through the water inlet is greater than the amount of water discharged through the drain pipe 8, and the water storage chamber of the water tank 7 is gradually filled, so that the overall weight of the water tank 7 gradually increases and decreases.

By setting a plurality of angle plates 20, the installation accuracy and reliability of the photovoltaic components are improved, and by setting the reinforcement frame 21, the support stability of the photovoltaic components is improved.

[0032] On sunny days, the elastic force of the spring 17 pushes the pin 16 upward, so that the upper end of the pin 16 is inserted into the positioning hole of the wheel disc 4, positioning the wheel disc 4 pin, improving the stability of the mounting frame 2, and the hook of the hook rod 13 is hooked on the hanging rod 14, thereby positioning and mounting the empty water tank 7.

On rainy days, rainwater flows downward along the photovoltaic components on the mounting frame 2 and is concentrated into the water storage chamber through the water inlet of the water tank 7. When it rains heavily, when the amount of water flowing into the water storage chamber of the water tank 7 through the water inlet is greater than the amount of water discharged through the drain pipe 8, the water storage chamber of the water tank 7 is gradually filled, so that the overall weight of the water tank 7 gradually increases. Then, in this process, the water level in the water storage chamber of the water tank 7 drives the float 12 to rise, and the float 12 drives the arm 11 to rotate around the shaft 10, so that the other end of the arm 11 pushes the latch 16 downward through the pressure rod 18, so that the upper end of the latch 16 is disengaged and unlocked from the wheel disc 4, and at the same time, the other end of the arm 11 pushes the lower end of the hook rod 13 outward through the sliding rod, so that the upper end of the hook rod 13 is hooked.

Then, when the force exerted by the water tank 7 on the wheel disc 4 through the cable 6 is greater than the elastic force of the torsion component 9, the water tank 7 pulls the wheel disc 4 to rotate through the cable 6, and the wheel disc 4 drives the mounting frame 2 to flip the pressure rod 180 degrees through the transmission member 5, so that the photovoltaic components on the mounting frame 2 face downward, and the metal plate on the back of the photovoltaic panel faces upward, so that the grille plate 22 protects the photovoltaic panel, prevents hail from hitting the photovoltaic panel, and prevents rainwater and sediment from eroding the photovoltaic panel, thereby reducing damage to the photovoltaic components. Finally, when the rainwater becomes less and the rainwater in the water tank 7 is discharged through the drain pipe 8, the elastic force of the torsion component 9 drives the mounting frame 2 to flip and reset, and the elastic force of the spring 17 pushes the pin 16 upward, so that the upper end of the pin 16 is inserted into the positioning hole of the wheel disc 4, the wheel disc 4 pin is positioned, and the hook of the hook rod 13 is hooked on the hanging rod 14, thereby positioning and mounting the empty water tank 7.
