Description

Technical Field

[0002] Solar power generation is called the most ideal new energy source, with three major advantages: permanence, cleanliness, and flexibility. Solar cells have a long lifespan. As long as the sun exists, solar cells can be invested once and used for a long time; compared with thermal power generation and nuclear power generation, solar cells do not cause environmental pollution.

[0064] In a preferred embodiment: The photovoltaic panel assembly 8 includes a photovoltaic panel main body 81 and an isolation assembly 82 sleeved on the outer wall of the photovoltaic panel main body 81;

[0065] The photovoltaic panel main body 81 includes a support rod 811. A support tube 812 is fixedly assembled on the outer wall of the top of the support rod 811, and a photovoltaic panel body 813 is fixedly assembled on the top of the support tube 812;

[0066] The isolation assembly 82 includes two sets of plug-in components 821 installed at both ends of the support tube 812, and an isolation main body 822 is sleeved on the outer walls of the two sets of plug-in components 821.

[0067] In a preferred embodiment: The support rod 811 includes a rod body 8111. A cleaning plate 8112 is fixedly assembled at the bottom of the rod body 8111, and a support rotating shaft 8113 is rotatably connected to the outer wall of the bottom of the rod body 8111;

[0068] The plug-in component 821 includes a plug-in block 8211, and rotating shaft bodies are installed at the upper and lower ends on the side of the plug-in block 8211 away from the support rotating shaft 8113;

[0069] The isolation main body 822 includes a transparent isolation film 8221. A meshing tooth 8223 is fixedly assembled on the outer wall of the side of the transparent isolation film 8221 close to the double-axis outputter 6. A plurality of convex lenses 8222 are fixedly assembled on the outer wall of the transparent isolation film 8221, and the convex lenses 8222 account for half of the circumference of the transparent isolation film 8221.

[0070] In a preferred embodiment: The meshing tooth 8223 meshes with the meshing groove 505. The isolation main body 822 is rotatably sleeved on the outer surface of the photovoltaic panel main body 81 through two sets of plug-in components 821, and the bottom of the transparent isolation film 8221 is located between the support rotating shaft 8113 and the cleaning plate 8112.

[0071] In a preferred embodiment: The plug-in block 8211 includes a plug-in seat 82111. A plug-in frame 82112 is fixedly assembled on the outer wall of the plug-in seat 82111. Telescopic rods 82114 are fixedly assembled on both the upper and lower sides of the plug-in frame 82112, and a driving shaft 82113 is installed on the side of the plug-in frame 82112 away from the plug-in seat 82111;

[0072] The rotating shaft body 8212 includes a rotating rod 82121, and a tube body 82122 is fixedly assembled on the outer wall of the rotating rod 82121;

[0073] The rotating shaft body 8212 is rotatably connected to the telescopic end of the telescopic rod 82114 through the rotating rod 82121, and the plug-in component 821 is sleeved on the isolation main body 822 through the tube body 82122.

[0074] In the above structure, it is fixedly assembled through the plug-in component 821 and the support tube 812. The plug-in component 821 is used to support the isolation main body 822, so that the isolation main body 822 is rotatably sleeved on the surface of the support rod 811. Furthermore, the isolation main body 822 realizes the isolation of the support rod 811. And the bottom of the transparent isolation film 8221 is located between the support rotating shaft 8113 and the cleaning plate 8112. When the isolation main body 822 rotates through the plug-in component 821, the isolation main body 822 can be scraped by the cleaning plate 8112, and then the dust on the surface of the isolation main body 822 is cleaned;

[0075] At the same time, a number of convex lenses 8222 are fixedly assembled on the outer wall of the transparent isolation film 8221. The arc surface of the convex lens 8222 is used to increase the contact surface with light. Through the refraction of light by the convex lens 8222, the amount of light received by the photovoltaic panel body 813 is increased;

[0076] The convex lens 8222 accounts for half of the circumference of the transparent isolation film 8221. When the servo motor 4 drives the photovoltaic panel assembly 8 to rotate through the double-axis output device 6 and changes the direction of the photovoltaic panel assembly 8, the isolation main body 822 rotates through the plug-in component 821 by using the meshing of the meshing teeth 8223 and the meshing groove 505. In the morning period, the transparent isolation film 8221 isolates the photovoltaic panel body 813, and light can directly pass through the transparent isolation film 8221 to enable the photovoltaic panel body 813 to receive light;

[0077] In the afternoon period, as the direction of the photovoltaic panel assembly 8 changes, the isolation main body 822 rotates, and the part of the transparent isolation film 8221 with the convex lens 8222 covers the photovoltaic panel body 813. Light is refracted by the convex lens 8222 to increase the amount of light received by the photovoltaic panel body 813;

[0078] In another state, when it rains, the photovoltaic panel assembly 8 can be rotated to make the part of the transparent isolation film 8221 with the convex lens 8222 cover the photovoltaic panel body 813. The plane between the two groups of convex lenses 8222 is used to divert water, so that the water flows out to the opposite ends of the two groups of photovoltaic panel assemblies 8, reducing the time for water to remain on the top of the photovoltaic panel assembly 8 and reducing the load of the photovoltaic panel assembly 8;

[0079] When the isolation main body 822 is installed on the plug-in component 821, the telescopic rod 82114 drives the rotating shaft main body 8212 to contract, and then the isolation main body 822 is sleeved on the plug-in component 821. The controller controls a group of telescopic rods 82114 at the top to expand and contract to adjust the distance between the convex lens 8222 and the photovoltaic panel body 813. After the adjustment is completed, the controller controls a group of telescopic rods 82114 at the bottom to expand and contract to realize the tensioning of the isolation main body 822;

[0080] The telescopic rod 82114 is used for telescoping to adjust the distance between the convex lens 8222 and the photovoltaic panel body 813, so as to change the area where the light source is concentrated on the surface of the photovoltaic panel body 813 through the convex lens 8222, avoiding the problem that too much light source is concentrated on the surface of the photovoltaic panel body 813, resulting in damage to the photovoltaic panel body 813. On the other hand, the controller controls the drive shaft 82113 to rotate, so that the drive shaft 82113 drives the isolation main body 822 to rotate, and the light source concentrated by the convex lens 8222 can be moved to different positions of the photovoltaic panel body 813 through the movement of the isolation main body 822, so as to realize the uniformity of the photovoltaic panel body 813 receiving the light source.

[0081] Working principle:

[0082] Through the fixed assembly of the bottom of the spring 404 and the ring body 501, and by using the circular groove 502 and the sliding groove 503, the fixed tooth tube 5 and the servo motor 4 are slidably sleeved, so that the fixed tooth tube 5 moves up and down. And by using the spring 404, the fixed tooth tube 5 is kept at the top of the servo motor 4 and is limited by the limiting block at the top of the middle plate body of the ring body 501, so that the meshing groove 505 and the meshing tooth 8223 maintain a meshing relationship.

[0083] The drive motor 605 drives two groups of rotating shafts 604 to rotate through the output body 603, so that the rotating shafts 604 drive the photovoltaic panel assembly 8 to rotate, thereby realizing the adjustment of the inclination angle of the photovoltaic panel assembly 8.

[0084] The servo motor 4 drives the double-axis output 6 to rotate. By using the meshing of the meshing groove 505 and the meshing tooth 8223, and through the fixed assembly of the plug-in assembly 821 and the support tube 812, the plug-in assembly 821 is used to support the isolation main body 822, so that the isolation main body 822 is rotatably sleeved on the surface of the support rod 811, and thus the isolation main body 822 realizes the isolation of the support rod 811. And since the bottom of the transparent isolation film 8221 is located between the support rotating shaft 8113 and the cleaning plate 8112, when the isolation main body 822 rotates through the plug-in assembly 821, the isolation main body 822 can be scraped by the cleaning plate 8112, and thus the dust on the surface of the isolation main body 822 is cleaned.

[0085] At the same time, a number of convex lenses 8222 are fixedly assembled on the outer wall of the transparent isolation film 8221. By using the arc surface of the convex lens 8222 to increase the contact surface with light, and through the refraction of light by the convex lens 8222, the amount of light received by the photovoltaic panel body 813 is increased.

[0086] The convex lens 8222 occupies half of the perimeter of the transparent isolation film 8221, enabling the servo motor 4 to drive the photovoltaic panel assembly 8 to rotate through the dual-axis output 6. While changing the direction of the photovoltaic panel assembly 8, the engagement of the meshing teeth 8223 and the meshing groove 505 causes the isolation body 822 to rotate through the plug-in assembly 821. During the morning period, the transparent isolation film 8221 isolates the photovoltaic panel body 813, and light can directly pass through the transparent isolation film 8221 to enable the photovoltaic panel body 813 to receive light.

[0087] During the afternoon period, as the direction of the photovoltaic panel assembly 8 changes, the isolation body 822 rotates, and the part of the transparent isolation film 8221 with the convex lens 8222 covers the photovoltaic panel body 813. The light is refracted by the convex lens 8222 to increase the amount of light received by the photovoltaic panel body 813.

[0088] In another set of states, during rain, the photovoltaic panel assembly 8 can be rotated so that the part of the transparent isolation film 8221 with the convex lens 8222 covers the photovoltaic panel body 813. The plane between the two convex lenses 8222 is used to divert water, causing the water to flow out towards the opposite ends of the two photovoltaic panel assemblies 8, reducing the time that water remains on top of the photovoltaic panel assembly 8 and reducing the load on the photovoltaic panel assembly 8.
