Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically an automatic cleaning device for street light solar panels. Background Technology

[0002] The automatic solar panel cleaning device for smart streetlights is an intelligent maintenance device integrated into the solar streetlight system. It aims to automatically remove pollutants such as dust, bird droppings, and leaves accumulated on the surface of solar panels to ensure the power generation efficiency of photovoltaic modules and the stable operation of streetlights. These devices typically use rain, light, or pollution sensors to determine when to clean, and use motor-driven brushes, scrapers, or water spray systems to periodically clean the solar panels without manual intervention. They are particularly suitable for widely distributed and inconveniently maintained urban smart streetlight networks. Their core objective is to improve energy conversion efficiency, extend system lifespan, and reduce overall operation and maintenance costs.

[0003] However, the brushes and scrapers in existing devices are prone to wear and tear during long-term friction with the glass surface of solar panels, leading to a gradual decrease in cleaning effectiveness and requiring regular replacement. Since smart streetlights are usually installed on high poles on both sides of the road, with the solar panels located several meters in the air, maintenance personnel must use aerial work platforms or ladders to perform high-altitude operations every time they replace the brushes or scrapers. This is not only cumbersome and time-consuming, but also poses significant safety risks. In addition, traditional fixing methods mostly use screws for fastening, and the disassembly and assembly process requires special tools, which is particularly inconvenient in outdoor environments, affecting the continuous and effective operation of the cleaning device. Therefore, we propose an automatic cleaning device for streetlight solar panels. Utility Model Content

It effectively reduces the safety risks of working at height. At the same time, the entire replacement process can be completed quickly within a short time of climbing, improving maintenance efficiency and solving the pain point of existing automatic cleaning devices where the cleaning function fails and the power generation efficiency is affected because the scraper is difficult to replace after wear.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1 to 8 This utility model provides a technical solution: an automatic cleaning device for street light solar panels, comprising: a solar panel body 1;

[0029] It also includes: a cleaning component 4, which is set on the upper part of the solar panel body 1. The cleaning component 4 is used to clean the dust on the surface of the solar panel body 1. The cleaning component 4 includes a connecting frame 41. A limiting component 42 is provided on one side of the connecting frame 41. A first guide rod 43 is fixedly connected to the inner cavity of the connecting frame 41. A scraper 45 is slidably connected to the inner cavity of the connecting frame 41. The scraper 45 is slidably connected to the first guide rod 43. A third spring 44 is provided on the side of the inner cavity of the connecting frame 41 away from the limiting component 42. The two sides of the third spring 44 are fixedly connected to the scraper 45 and the inner wall of the connecting frame 41, respectively.

[0030] Support component 2 is located at the lower part of the solar panel body 1 and is used to support the solar panel body 1.

[0031] Drive component 3 is located on the upper part of the solar panel body 1. Drive component 3 is used to drive the cleaning component 4 to move.

[0032] When the scraper 45 needs to be replaced, the worker applies force to the limiting component 42 to release the position restriction of the scraper 45 in the inner cavity of the connecting frame 41. Then, under the elastic force of the third spring 44, the third spring 44 will be extended, which will push the scraper 45 to slide away from the third spring 44 in the inner cavity of the connecting frame 41. This makes it easier for the worker to remove the scraper 45 from the inner cavity of the connecting frame 41. Then, the new scraper 45 is slid and pushed into the inner cavity of the connecting frame 41, and the limiting component 42 is used to limit the position of the scraper 45 in the inner cavity of the connecting frame 41, thereby completing the replacement of the scraper 45. This reduces the complexity of operation and the operation time, avoids the tedious process of carrying tools and disassembling one by one under the traditional screw fixing method, effectively reduces the safety risks of working at height. At the same time, the entire replacement process can be completed quickly within a short time of climbing, improving maintenance efficiency and solving the pain point of existing automatic cleaning devices where the cleaning function fails and the power generation efficiency is affected because the scraper 45 is difficult to replace after wear.

[0033] The limiting component 42 includes a housing 421 fixedly connected to the connecting frame 41, and the inner cavity of the housing 421 communicates with the inner cavity of the connecting frame 41. A support ring 47 is fixedly connected to the inner cavity of the housing 421 near the scraper 45. A limiting post 424 is slidably connected to the inner cavity of the housing 421. The limiting post 424 is slidably connected to the support ring 47. A first circular plate 422 is fixedly connected to the side of the limiting post 424 away from the scraper 45. The inner cavity of the housing 421 is slidably connected to the first circular plate 422. A first spring 423 is wound around the side of the limiting post 424 away from the scraper 45. The two sides of the first spring 423 are fixedly connected to the side of the first circular plate 422 away from the scraper 45 and the inner wall of the housing 421, respectively. A limiting groove 451 is opened on the side of the scraper 45 near the limiting post 424.

[0034] A connecting shaft 427 is slidably connected to the middle of the outer shell 421. A second annular plate 428 is slidably connected to the middle of the inner cavity of the outer shell 421. A second wedge 426 is fixedly connected to the side of the connecting shaft 427 near the limiting post 424. A first wedge 425 is fixedly connected to the side of the limiting post 424 near the second wedge 426. A second spring 429 is wound around the outer surface of the connecting shaft 427. A partition 46 is fixedly connected to the middle of the inner cavity of the outer shell 421. The two sides of the second spring 429 are fixedly connected to the side of the partition 46 near the second annular plate 428 and the side of the second annular plate 428 away from the partition 46, respectively. The side of the first wedge 425 near the second wedge 426 and the side of the second wedge 426 near the first wedge 425 are both inclined. The scraper 45 is T-shaped.

[0035] When the scraper 45 needs to be replaced, the worker climbs up a ladder, presses the connecting shaft 427, applies force to the connecting shaft 427, causing it to slide towards the limiting post 424. This causes the second annular plate 428 to slide in the middle of the inner cavity of the outer casing 421 towards the limiting post 424, which in turn causes the second spring 429 to contract. As the connecting shaft 427 slides, it causes the second wedge block 426 to slide towards the limiting post 424, thus causing the second wedge block 426 to move against the adjacent... The first wedge 425 applies force, causing it to slide away from the scraper 45. This causes the limiting post 424 to slide away from the scraper 45, separating the side of the limiting post 424 closest to the scraper 45 from the inner cavity of the limiting groove 451. This releases the position restriction of the scraper 45 within the inner cavity of the connecting frame 41. As the limiting post 424 moves, it causes the first annular plate 422 to slide within the inner cavity of the outer shell 421, which in turn causes the first spring 423 to contract. When the position restriction of the scraper 45 is released... After setting, under the elastic force of the third spring 44, the third spring 44 will extend, which will push the scraper 45 to slide away from the third spring 44 in the inner cavity of the connecting frame 41. This makes it easier for the worker to remove the scraper 45 from the inner cavity of the connecting frame 41. Then, a new scraper 45 is slid and pushed into the inner cavity of the connecting frame 41. During the replacement process, the worker releases the force applied to the connecting shaft 427, and then under the elastic force of the second spring 429, the second ring plate 428 will move in the inner cavity of the outer shell 421. The first part slides away from the limiting post 424, which in turn drives the second wedge block 426 to slide away from the limiting post 424. Then, under the elastic force of the first spring 423, the first spring 423 will extend, which will drive the first annular plate 422 to slide towards the scraper 45. Then, the limiting post 424 will slide towards the scraper 45 and into the inner cavity of the limiting groove 451, thereby limiting the position of the scraper 45 in the inner cavity of the connecting frame 41, and then completing the replacement of the scraper 45.

[0036] Example 2

[0037] The drive assembly 3 includes a first slide block 31, a second slide block 32, and two sliders 33. The lower ends of the two sliders 33 are fixedly connected to the upper end of the connecting frame 41. The inner cavity of the first slide block 31 is slidably connected to the adjacent slider 33, and the inner cavity of the second slide block 32 is slidably connected to the adjacent slider 33. A support plate 34 is fixedly connected to one side of the upper end of the second slide block 32, and a motor 35 is provided on one side of the support plate 34. A threaded rod 37 is rotatably connected to the inner cavity of the second slide block 32. The threaded rod 37 is threadedly connected to the adjacent slider 33, and the threaded rod 37 is close to the support plate 34. A first gear 36 is fixedly connected to one side of the plate 34, and a second gear 38 is meshed with one side of the first gear 36. The output shaft of the motor 35 is fixedly connected to the second gear 38. The support assembly 2 includes a bracket 21 fixedly connected to the lower end of the solar panel body 1. Connecting blocks 22 are symmetrically fixedly connected to the bracket 21. A first slide block 31 is fixedly connected to the adjacent connecting block 22. A second slide block 32 is fixedly connected to the adjacent connecting block 22. A support rod 23 is fixedly connected to the middle of the lower end of the bracket 21. A street lamp body 24 is fixedly connected to one side of the support rod 23.

[0038] The entire device is supported by the cooperation of bracket 21 and support rod 23. The entire drive assembly 3 is supported by the cooperation of connecting block 22, first slide rail block 31, and second slide rail block 32. When cleaning the surface of the solar panel body 1, the controller controls the motor 35 to run. The output shaft of the motor 35 drives the second gear 38 to rotate. Then, the second gear 38 meshes with the adjacent first gear 36, causing the first gear 36 to rotate. The first gear 36 drives the threaded rod 37 to rotate. Since the threaded rod 37 is threadedly connected to the adjacent slider 33, when the threaded rod 37 rotates, it will drive the slider 33 to slide in the inner cavity of the second slide rail block 32. Since the lower end of the slider 33 is fixedly connected to the upper end of the connecting frame 41, when the slider 33 moves, it will drive the connecting frame 41 to move together. Then, the connecting frame 41 drives the scraper 45 to move, thereby cleaning the surface of the solar panel body 1.
