[0002] The photovoltaic power generation set with adjustable multi - angles can dynamically adjust the angle of the photovoltaic panel (or photovoltaic module) through the built - in adjustment mechanism, enabling it to always face the best illumination direction of sunlight. This design aims to maximize the absorption of sunlight, thereby improving the efficiency and output of photovoltaic power generation.

[0003] For example, the publication number is CN118920976A. This invention relates to the technical field of photovoltaic power generation, and particularly to a photovoltaic power generation set with adjustable angles, including a number of adjustment modules. The adjustment modules are used to adjust the angle of the photovoltaic module. The adjustment module includes a fixed frame, inside which a photovoltaic panel is arranged. The bottom surface of the fixed frame is fixedly connected with a fixed seat, and two support rods are arranged at the bottom of the fixed frame. An adjustment mechanism is arranged at the top of the support rod. In this invention, by the inner side of the fixed rod being rotatably connected with the sliding rod, the angle of the photovoltaic panel can be adjusted in a timely manner according to the sunlight angle, making the sunlight shine perpendicularly on the photovoltaic panel as much as possible, which is beneficial to improving the utilization rate of sunlight by the photovoltaic panel. And in snowy days and freezing rain weather, the fixed frame can be adjusted to the vertical state or the back of the fixed frame can be turned upwards, and the snow and rain will fall on the back of the fixed frame, avoiding contact with the photovoltaic panel, thereby avoiding affecting the power generation efficiency of the photovoltaic panel.

[0004] In the above - mentioned prior art, the angle of the photovoltaic panel is adjusted through the driving component, making the sunlight shine perpendicularly on the photovoltaic panel as much as possible to improve the utilization rate of sunlight by the photovoltaic panel. And in bad weather, the fixed frame can be adjusted to the vertical state or the back of the fixed frame can be turned upwards, and the snow and rain will fall on the back of the fixed frame, avoiding contact with the photovoltaic panel, thereby avoiding affecting the power generation efficiency of the photovoltaic panel.

[0018] 2. In the present invention, the push-pull plate is set in an inclined state and squeezes the second cleaning plate during the upward movement of the protective cover. The second cleaning plate is pressed to squeeze the push-pull plate through the first connecting shaft. When the push-pull plate is pressed, it deflects around the second connecting shaft. Therefore, the limiting rod gradually slides from the middle of the protective cover to both sides along the trajectory of the limiting rod. When the protective cover rises completely, the second cleaning plate is located on the outermost side of the protective cover, and the push-pull plate is in a horizontal state. Therefore, the second cleaning plate cleans the dust on the protective cover, avoiding dust or garbage that may be avoided when protecting the photovoltaic panel during the upward movement from polluting the photovoltaic panel.

[0019] 3. In the present invention, when the drive motor is started, the threaded rod rotates, driving the slider to slide along the trajectory of the chute.

The driving assembly includes a dual-axis motor 22, and the dual-axis motor 22 is fixed inside the bottom end of the mounting base 1. The two ends of the dual-axis motor 22 are transmission-connected with a first rotating rod 221, and the end of the first rotating rod 221 away from the dual-axis motor 22 is fixedly connected to a second gear 222, and the side of the second gear 222 away from the dual-axis motor 22 is meshed with a third gear 224, and the middle part of the third gear 224 is fixedly connected to a second rotating rod 223, and the second rotating rod 223 is rotationally connected to the mounting base 1 and is located inside the lifting slot.

[0033] In this embodiment, the staff starts the dual-axis motor 22. The dual-axis motor 22 drives the first rotating rod 221 to rotate. The first rotating rod 221 drives the second gear 222 to rotate. The second gear 222 drives the third gear 224 to rotate. The third gear 224 drives the second rotating rod 223 to rotate. The second rotating rod 223 drives the lifting cylinder 23 to rotate. The lifting cylinder 23 drives the fourth gear 231 to rotate. The top fourth gear 231 drives the first gear 213 to rotate.

During the operation of the photovoltaic panel 211, the driving machine 216 is started to drive the threaded rod 215 to rotate. The threaded rod 215 drives the slider 217 to slide along the track of the chute 214. The slider 217 drives the first cleaning plate 218 to slide, which can clean the surface of the photovoltaic panel 211, avoiding the reduction of power generation efficiency caused by the accumulation of dust on the surface during long-term operation.

Therefore, the first cleaning plate 218 can clean the back side to prevent the back side of the photovoltaic panel 211 from being corroded.

[0034] As Figure 1 - Figure 8 shown, the conversion assembly includes a lifting cylinder 23. The lifting cylinder 23 is slidably connected to the top of the second rotating rod 223 and is located inside the lifting groove. Both ends of the lifting cylinder 23 are fixedly connected with fourth gears 231. The top fourth gear 231 meshes with the first gear 213. A support plate 234 is rotatably connected to the side of the lifting cylinder 23 where the fourth gears 231 are close to each other. The support plate 234 is fixedly connected to the mounting base 1. A cylinder 233 is fixedly connected to the top of the bottom support plate 234. A push plate 232 is fixedly connected to the top of the cylinder 233. The push plate 232 is slidably connected to the mounting base 1 and is rotatably connected to the lifting cylinder 23. The protection assembly includes a protective cover 31. The protective cover 31 is fixed to the top of the middle of the mounting base 1. Connecting blocks 311 are fixedly connected to the middle of both sides of the top of the protective cover 31. The connecting blocks 311 are slidably connected to the lifting groove. Clamping rods 314 are fixedly connected to the side of the top of the connecting blocks 311 where they are close to each other. The clamping rods 314 are clamped with the fixing grooves 2121. A second lead screw 312 is threadedly connected to the side of the connecting block 311 away from the protective cover 31. The second lead screw 312 is rotatably connected to the mounting base 1. A fifth gear 313 is fixedly connected to the bottom of the second lead screw 312. The fifth gear 313 meshes with the bottom fourth gear 231.

[0035] In this embodiment, the support plate 234 is rotatably or slidably connected to the lifting cylinder 23, and the lifting cylinder 23 and the push plate 232 are also rotatable or slidable. When encountering bad weather, the mounting frame 21 is driven by the dual-axis motor 22 to rotate counterclockwise to a horizontal state, so that the back of the photovoltaic panel 211 faces upward. Then, the cylinder 233 is started to drive the push plate 232 to slide downward. The push plate 232 drives the lifting cylinder 23 to move downward. The lifting cylinder 23 drives the fourth gear 231 at the top to move downward. The fourth gear 231 at the top is separated from the first gear 213, and the fourth gear 231 at the bottom meshes with the fifth gear 313. Therefore, the second rotating rod 223 rotates to drive the lifting cylinder 23 to rotate. The lifting cylinder 23 drives the fourth gear 231 at the bottom to rotate. The fourth gear 231 at the bottom drives the fifth gear 313 to rotate. The fifth gear 313 drives the second lead screw 312 to rotate. The second lead screw 312 drives the connecting block 311 to move upward. The connecting block 311 drives the protective cover 31 to move upward, and finally contacts the front surface of the photovoltaic panel 211, so as to shield and protect the surface after the photovoltaic panel 211 is flipped 180 degrees, and avoid being contaminated and damaged on the surface in bad weather such as rain and snow. The connecting block 311 moves to drive the clamping rod 314 to rise. When the protective cover 31 contacts the photovoltaic panel 211, the clamping rod 314 enters the fixing groove 2121, so as to fix the photovoltaic panel 211 and avoid damage to the mounting frame 21 caused by the photovoltaic panel 211 swaying back and forth under the action of wind force in strong wind weather.

[0036] As Figure 1 - Figure 8 As shown in the figure, the cleaning assembly includes a limiting rod 32. The limiting rod 32 is fixed on both sides of the top of the protective cover 31. The middle part of the limiting rod 32 is slidably connected with a second cleaning plate 321. Both ends of the second cleaning plate 321 are fixedly connected with a first connecting shaft 322. One end of the first connecting shaft 322 away from the second cleaning plate 321 is rotatably connected with a push-pull plate 323. The top of the push-pull plate 323 is rotatably connected with a second connecting shaft 324. The second connecting shaft 324 is fixed on both sides of the mounting seat 1 at the top of the lifting groove, and the push-pull plate 323 is in an inclined state.

[0037] In this embodiment, since the push-pull plate 323 is set in an inclined state, the second cleaning plate 321 is squeezed during the upward movement of the protective cover 31. The second cleaning plate 321 is pressed to squeeze the push-pull plate 323 through the first connecting shaft 322. The push-pull plate 323 is pressed to deflect around the second connecting shaft 324. Therefore, the limiting rod 32 gradually slides from the middle of the protective cover 31 to both sides along the track of the limiting rod 32. When the protective cover 31 rises completely, the second cleaning plate 321 is located on the outermost side of the protective cover 31, and the push-pull plate 323 is in a horizontal state. Therefore, the second cleaning plate 321 cleans the dust on the protective cover 31, and avoids the dust or garbage that is avoided when protecting the photovoltaic panel 211 from rising from contaminating the photovoltaic panel 211.

[0038] Working principle: First, the staff starts the double-shaft motor 22. The double-shaft motor 22 drives the first rotating rod 221 to rotate. The first rotating rod 221 drives the second gear 222 to rotate. The second gear 222 drives the third gear 224 to rotate. The third gear 224 drives the second rotating rod 223 to rotate. The second rotating rod 223 drives the lifting cylinder 23 to rotate. The lifting cylinder 23 drives the fourth gear 231 to rotate. The top fourth gear 231 drives the first gear 213 to rotate. The first gear 213 drives the adjusting shaft 212 to rotate. The adjusting shaft 212 drives the mounting bracket 21 to rotate, achieving angle deflection. When encountering bad weather, the double-shaft motor 22 drives the mounting bracket 21 to rotate counterclockwise to a horizontal state, making the back of the photovoltaic panel 211 face upward. Then, the cylinder 233 is started to drive the push plate 232 to slide downward. The push plate 232 drives the lifting cylinder 23 to move downward. The lifting cylinder 23 drives the fourth gear 231 to move downward. The top fourth gear 231 is separated from the first gear 213, and the bottom fourth gear 231 meshes with the fifth gear 313. Therefore, the second rotating rod 223 rotates to drive the lifting cylinder 23 to rotate. The lifting cylinder 23 drives the bottom fourth gear 231 to rotate. The bottom fourth gear 231 drives the fifth gear 313 to rotate. The fifth gear 313 drives the second lead screw 312 to rotate. The second lead screw 312 drives the connecting block 311 to move upward. The connecting block 311 drives the protective cover 31 to move upward, and finally contacts the front of the photovoltaic panel 211, so as to shield and protect the surface after the photovoltaic panel 211 is flipped 180 degrees, avoiding surface pollution and damage in bad weather such as rain and snow. The connecting block 311 moves to drive the clamping rod 314 to rise. When the protective cover 31 contacts the photovoltaic panel 211, the clamping rod 314 enters the fixing groove 2121, so as to fix the photovoltaic panel 211, avoiding damage to the mounting bracket 21 caused by the photovoltaic panel 211 swaying back and forth under the action of wind in strong wind weather. Since the push-pull plate 323 is set in an inclined state, the second cleaning plate 321 is squeezed during the upward movement of the protective cover 31. The second cleaning plate 321 is pressed to squeeze the push-pull plate 323 through the first connecting shaft 322. The push-pull plate 323 is pressed to deflect around the second connecting shaft 324. Therefore, the limiting rod 32 gradually slides from the middle of the protective cover 31 to both sides along the trajectory of the limiting rod 32. When the protective cover 31 rises completely, the second cleaning plate 321 is located on the outermost side of the protective cover 31, and the push-pull plate 323 is in a horizontal state. Therefore, the second cleaning plate 321 cleans the dust on the protective cover 31, avoiding dust or garbage on the protective cover 31 from polluting the photovoltaic panel 211 when it rises to protect the photovoltaic panel 211. Among them, during the operation of the photovoltaic panel 211, the driving machine 216 is started to drive the threaded rod 215 to rotate. The threaded rod 215 drives the slider 217 to slide along the trajectory of the chute 214. The slider 217 drives the first cleaning plate 218 to slide, which can clean the surface of the photovoltaic panel 211, avoiding a reduction in power generation efficiency caused by dust accumulation on the surface during long-term operation. And when the photovoltaic panel 211 is flipped and protected, the back faces upward, and the back will be polluted by rain and dust in bad weather.Therefore, the first cleaning plate 218 can clean the back surface to prevent the back surface of the photovoltaic panel 211 from being corroded.
