[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0023] See also Figure 1-Figure 7 The present invention provides a technical solution: an energy-saving foldable lighting street lamp, comprising a lamp pole 1, a connecting seat 5 is fixedly installed on the lamp pole 1, a mounting plate 6 is movably installed on the connecting seat 5, a solar panel 7 and a connecting box 16 are fixedly installed on the mounting plate 6, a cleaning roller 8 is movably installed on the side of the connecting box 16, and a mode conversion component is arranged in the connecting box 16. The mode conversion component has two modes, namely a first mode and a second mode. The first mode adjusts the cleaning roller 8 and the solar panel 7 to contact each other, and the cleaning roller 8 cleans the solar panel 7.

[0024] In this embodiment, a first rotating column 22 is movably installed in the connecting box 16, and a first rotating gear 23 is fixedly installed outside the first rotating column 22. The end of the first rotating column 22 is fixedly connected to the cleaning roller 8. When the first rotating gear 23 rotates, the cleaning roller 8 can be driven to rotate through the first rotating column 22, so that the cleaning roller 8 can be changed from the original position perpendicular to the solar panel 7 to the position parallel to and in contact with the solar panel 7, so that the cleaning roller 8 can clean the solar panel 7 conveniently.

[0025] In this embodiment, a mounting block 17 is also provided on the solar panel 7, and the mounting block 17 includes a connecting channel 18, a piston plate 19 and a bevel rod 20. The piston plate 19 and the bevel rod 20 are in contact through a bevel, and a first extrusion spring 21 is provided on the bevel rod 20. The bevel rod 20 passes through the mounting block 17 and penetrates into the connecting box 16 to be meshed and connected with the first rotating gear 23. The piston plate 19 in the mounting block 17 is subjected to the pressure from the connecting channel 18 and moves in the mounting block 17. When the piston plate 19 moves, it drives the bevel rod 20 to move toward the outside of the mounting block 17 through the bevel, and when the bevel rod 20 moves, it also compresses the first extrusion spring 21. At the same time, the shape of the bevel rod 20 is Z-shaped. The bevel rod 20 extends out of the mounting block 17 but enters the connecting box 16 to drive the first rotating gear 23 to rotate, thereby driving the angle of the cleaning roller 8 to change.

[0026] In this embodiment, a steel cable 12 and a lead screw 14 are arranged in the mounting plate 6, a threaded block 15 is arranged on the outer side of the lead screw 14, the threaded block 15 is fixedly connected to the connecting box 16, a second rotating gear 25 is arranged at the end of the threaded block 15, a first rack column 24 is arranged at the end of the steel cable 12, the first rack column 24 is meshed and connected with the second rotating gear 25, and a second extrusion spring 26 is arranged on the side of the first rack column 24, when the steel cable 12 is subjected to a downward pulling force, the first rack column 24 will drive the first rack column 24 to move, and the first rack column 24 will squeeze the second extrusion spring 26 when moving, and will drive the second rotating gear 25 to rotate, and the second rotating gear 25 will drive the lead screw 8 to rotate when rotating, and when the lead screw 8 rotates, it will drive the threaded block 15 to move on the mounting plate 6, and when the threaded block 15 moves, it will drive the cleaning roller 8 to move on the solar panel 7 through the connecting box 16 to clean the leaves and other debris on the surface of the solar panel 7.

[0027] See also Figure 8-Figure 13 The present invention provides a technical solution: in this embodiment, a first pushing component and a second pushing component are provided in the connecting frame 2, the first pushing component provides a power source for the mode conversion component, and the second pushing component can adjust the inclination angle of the solar panel 7, thereby increasing the inclination angle of the solar panel 7 when being cleaned by the cleaning roller 8, and facilitating the cleaning of the solar panel 7 by the cleaning roller 8 so that debris on the solar panel 7 can fall quickly.

[0028] In this embodiment, the first pushing component includes an inclined panel 27, on which a rack plate 9, a protective plate 10, a pushing column 28 and a pull rope 31 are arranged. The pull rope 31 extends through the connecting frame 2 and is a power source for the movement of the inclined panel 27. A diagonal support rod 3 is arranged on the side of the lamp pole 1, and a connecting rod 4 is arranged on the diagonal support rod 3. A street lamp is arranged on the connecting rod 4. The rack plate 9 is meshed and connected with the connecting rod 4, but when the connecting rod 4 is folded, the connecting rod 4 needs to be rotated at a certain angle before it is meshed and contacted with the rack plate 9. The street lamp on the adjustable connecting rod 4 can be folded, and when folded, it can also be another power source for the lifting of the cleaning roller 8. A fixing rod is provided on the connecting frame 2, and the fixing rod is connected to the connecting rod 4 by a pin, and a fan gear is provided at the end of the connecting rod 4, and the fan gear is meshed and connected with the rack plate 9. When the connecting rod 4 is tilted, the rack plate 9 can be driven to move horizontally by the fan gear, and the inclined panel 27 can be driven to move. The diagonal support rod 3 can be a telescopic rod, and the connecting rod 4 can be adjusted to be folded.

[0029] In this embodiment, a connecting pipe 11 is provided on the connecting frame 2, and the connecting pipe 11 is connected with the mounting block 17 through a connecting channel 18. A piston column 33 is provided in the connecting pipe 11, and the piston column 33 contacts the inclined plate 27 through an inclined surface, and the protective plate 10 can keep the piston column 33 in a stable state. When the inclined plate 27 moves, the piston column 33 will be driven to move into the connecting pipe 11. When the piston column 33 moves in the connecting pipe 11, it will provide a driving force for the movement of the piston plate 19 through the connecting channel 18. When the inclined plate 27 pushes the piston column 33 completely into the connecting pipe 11, the protective plate 10 will contact the bottom end of the piston column 33 and keep the piston column 33 in the same position in the connecting pipe 11, preventing the position of the piston plate 19 from changing, thereby preventing the cleaning roller 8 from suddenly rotating and separating from the solar panel 7 when the cleaning roller 8 is in contact with the surface of the solar panel 7 and performing cleaning work.

[0030] In this embodiment, the second pushing assembly includes a fixed frame 29, a connecting column 30 and a third extrusion spring 36. The third extrusion spring 36 is arranged inside the fixed frame 29, and a sliding block 35 is arranged on the third extrusion spring 36. The steel cable 12 passes through the sliding block 35 and is fixedly connected to the sliding block 35.

[0031] In this embodiment, a protective wheel group 34 is provided below the fixed frame 29, and the steel cable 12 is in contact with the surface of the protective wheel group 34. An engaging groove 32 matching the pushing steel cable 12 is opened on the pushing column 28. When the inclined panel 27 continues to move, it will contact the steel cable 12 through the pushing column 28 and the engaging groove 32. As the pushing column 28 contacts and continues to move, the steel cable 12 will bend and drive the sliding block 35 to squeeze the third extrusion spring 36. At the same time, the steel cable 12 located in the mounting plate 6 will drive the first rack column 24 to move, and can drive the screw 14 to rotate through the second rotating gear 25.

[0032] In this embodiment, the pushing column 28 is movably connected to the connecting column 30, and a supporting column 13 is provided at the other end of the connecting column 30. The other end of the supporting column 13 is in contact with the mounting plate 6. The supporting column 13 is in sliding contact with the inner wall of the connecting frame 2 and is parallel to the inner wall of the connecting frame 2.

[0033] When the pushing column 28 moves, it will drive the support column 13 to move upward through the connecting column 30, and the top end of the support column 13 will be in active contact with the bottom end of the mounting plate 6, so that when the support column 13 moves upward, the mounting plate 6 will change its angle through the connecting seat 5, so that when the cleaning roller 8 is cleaning, debris such as leaves on the solar panel 7 will fall off quickly to prevent accumulation.

[0034] When the inclined plate pushes the piston column completely into the connecting pipe, the protective plate will keep the piston column in the same position in the connecting pipe to prevent the position of the piston plate from changing, thereby preventing the cleaning roller from suddenly turning and separating from the solar panel during the cleaning process, thereby ensuring the continuity and stability of the cleaning work.

[0035] The structural design in the second pushing component, such as the pushing column driving the supporting column to move upward through the connecting column, changes the angle of the mounting plate, so that leaves and other debris on the solar panel can fall off quickly during cleaning to prevent accumulation, thereby improving cleaning efficiency and reducing cleaning time and labor costs.

[0036] After the cleaning work is completed, relying on the cooperation of the first extrusion spring, the second extrusion spring and the third extrusion spring, the cleaning roller can return to its original position, perpendicular to and separated from the solar panel, which can prevent the cleaning roller from contacting the solar panel and affecting the solar energy conversion efficiency, and avoid the temperature increase of the contact part to damage the solar panel. At the same time, it also prevents the cleaning roller from blocking the falling of debris, thereby extending the service life of the solar panel and ensuring its long-term stable performance.

[0037] The working principle of this embodiment is as follows: when the pull rope 31 or the connecting rod 4 is folded, the inclined plate 27 will move in the connecting frame 2. First, after the inclined plate 27 pushes the piston column 33 completely into the connecting tube 11, the protective plate 10 will contact the bottom end of the piston column 33 and keep the piston column 33 in the same position in the connecting tube 11, preventing the position of the piston plate 19 from changing, thereby preventing the cleaning roller 8 from suddenly turning an angle and separating from the solar panel 7 when the cleaning roller 8 is in contact with the surface of the solar panel 7 and performing cleaning work.

[0038] When the piston plate 19 moves, it will drive the inclined rod 20 to move toward the outside of the mounting block 17 through the inclined surface, and when the inclined rod 20 moves, it will also compress the first extrusion spring 21. At the same time, the shape of the inclined rod 20 is Z-shaped. The inclined rod 20 extends out of the mounting block 17 but enters the connecting box 16 to drive the first rotating gear 23 to rotate, thereby driving the angle of the cleaning roller 8 to change.

[0039] As the inclined plate 27 continues to move, it will contact the steel cable 12 through the pushing column 28 and the engaging groove 32. As the pushing column 28 contacts and continues to move, the steel cable 12 will bend and drive the sliding block 35 to squeeze the third extrusion spring 36. At the same time, the steel cable 12 located in the mounting plate 6 will drive the first rack column 24 to move, and can drive the screw 14 to rotate through the second rotating gear 25.

[0040] When the lead screw 8 rotates, it drives the threaded block 15 to move on the mounting plate 6 . When the threaded block 15 moves, it drives the cleaning roller 8 to move on the solar panel 7 through the connecting box 16 to clean the leaves and other debris on the surface of the solar panel 7 .

[0041] When the push column 28 moves, it will drive the support column 13 to move upward through the connecting column 30, and the top end of the support column 13 will be in active contact with the bottom end of the mounting plate 6, so that when the support column 13 moves upward, the mounting plate 6 will change its angle through the connecting seat 5, so that when the cleaning roller 8 is cleaning, debris such as leaves on the solar panel 7 will fall off quickly to prevent accumulation.

[0042] When the cleaning work is completed, the pull rope 31 is released or the connecting rod 4 returns to its original position. Under the cooperation of the first extrusion spring 21, the second extrusion spring 26 and the third extrusion spring 36, the cleaning roller 8 returns to its original position and is perpendicular to the solar panel 7 again, and is separated from the solar pick plate 7 to prevent contact with the solar panel 7 and affect the solar panel 7's conversion of solar energy. At the same time, it prevents the temperature of the contact part between the cleaning roller 8 and the solar panel 7 from rising and damaging the solar panel 7. At the same time, it can also prevent the cleaning tube 8 from hindering the falling of debris such as leaves on the solar pick plate 7.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
