Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, and in particular to a cleaning robot for photovoltaic panel modules. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that uses semiconductor materials to convert light energy into direct current (DC). Its core principle is based on the photovoltaic effect, achieving stable power generation through a solid-state structure with no moving parts. It is suitable for powering small electronic devices, building surface integration, and grid-connected power systems. The panel mainly consists of laminated components, an aluminum alloy frame, and a junction box. During use, PV panels require cleaning robots to remove dust.

[0003] When selecting a citrus orchard as the location for the photovoltaic power plant, the orchard is situated in a mountainous terrain with significant elevation changes and a relatively dispersed location. Several rural roads pass through the main photovoltaic area, and most of the transport roads are unpaved. Especially in the photovoltaic construction area, transport vehicles kick up dust as they enter and exit, which then settles on the photovoltaic panels, citrus trees, and fruit, severely impacting the power generation of the photovoltaic panels and the surrounding environment. Therefore, it is necessary to remove pollutants from the photovoltaic panels. Existing methods include manual washing, air dust removal, tracked robots, and drones. In complex terrain, tracked cleaning robots are required. However, these robots are not ideal for removing stubborn pollutants from the photovoltaic panels, often leaving residual contaminants. This makes effective cleaning of the photovoltaic panels inconvenient and reduces the overall effectiveness of the cleaning robots. Utility Model Content

[0004] Therefore, it is necessary to provide a cleaning robot for photovoltaic panel modules to address the problem of inconvenience in effectively cleaning photovoltaic panel modules.

[0005] The system includes a mounting plate with two rotating wheels rotatably connected to both ends; a cleaning mechanism, which improves the cleaning effect of the cleaning robot on photovoltaic panels, is disposed on the inner wall of the mounting plate; wherein, the cleaning mechanism includes two cleaning brushes rotatably connected to the inner wall of the mounting plate, one end of each cleaning brush is fixedly connected to a first gear, one side of each of the two first gears is meshed with a second gear, the two second gears mesh with each other, and a blowing assembly is provided on one side of the inner wall of the mounting plate.

[0006] In one embodiment, the cleaning mechanism further includes a water guide pipe disposed on the other side of the inner wall of the mounting plate, and one side of the water guide pipe is connected to several uniformly arranged low-pressure nozzles.

[0007] In one embodiment, a motor is mounted on the other end of the inner wall of the mounting plate, and the output shaft of one end of the motor is fixedly connected to one of the cleaning brushes.

[0008] In one embodiment, a first scraper is fixedly connected to the other side of the bottom of the mounting plate, and the first scraper is disposed on the other side of another cleaning brush.

[0009] In one embodiment, the purging assembly includes a plurality of mounting slots formed on the other side of the inner wall of the mounting plate, wherein a fan is mounted on the inner wall of the mounting slots and the fan is located on the other side of the first scraper.

[0010] In one embodiment, an air guide plate is fixedly connected to the other side of the bottom of the mounting plate, and an air outlet groove is formed on the inner wall of the air guide plate, which is in communication with the mounting groove.

[0011] In one embodiment, a number of evenly arranged filters are fixedly connected to the top of the mounting plate, and the filters are positioned above the fan.

[0012] In one embodiment, a second scraper is provided on the other side of the air guide plate, and the second scraper is fixedly connected to the mounting plate.

[0013] Beneficial effects

[0014] 1. The cleaning robot for the photovoltaic panel module described above has two cleaning brushes on the mounting plate that rotate synchronously through two first gears at one end and two second gears at the other end. The two second gears are positioned between the two first gears, allowing the two first gears to rotate in opposite directions, thus driving the two cleaning brushes to rotate in opposite directions and improving the cleaning effect of the cleaning brushes on the photovoltaic panel module. The motor can drive one of the cleaning brushes to rotate. Multiple low-pressure nozzles on one side of the water pipe can spray water to wash away impurities on the photovoltaic panel. The first scraper has a T-shaped structure and can scrape the surface of the photovoltaic panel module after cleaning as the mounting plate moves. The bottom of the first scraper is made of rubber, which will not damage the photovoltaic panel module and can improve the cleaning effect of the cleaning robot on the photovoltaic panel module, keeping the photovoltaic panel module clean.

[0015] 2. After the photovoltaic panel module is cleaned and residual moisture and impurities are scraped off by the first scraper, multiple fans in the mounting slot rotate to blow out airflow. The airflow passes through the air outlet at the bottom of the air guide plate and blows onto the surface of the photovoltaic panel module to dry the moisture on the surface of the photovoltaic panel module and prevent dust from sticking to the surface of the photovoltaic panel module. The second scraper can block external dust and scrape off residual impurities on the photovoltaic panel module, which can effectively clean the photovoltaic panel module and improve the cleaning effect of the cleaning robot.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figure 1 - Figure 5 This invention describes a cleaning robot for photovoltaic panel modules.

[0026] In one embodiment, a cleaning robot for photovoltaic panel modules includes a mounting plate 100, with two rotating wheels 200 rotatably connected to both ends of the mounting plate 100; a cleaning mechanism 300, which can improve the cleaning effect of the cleaning robot on the photovoltaic panel modules, is disposed on the inner wall of the mounting plate 100; wherein, the cleaning mechanism 300 includes two cleaning brushes 310 rotatably connected to the inner wall of the mounting plate 100, one end of the cleaning brushes 310 is fixedly connected to a first gear 320, and one side of each of the two first gears 320 is meshed with a second gear 330, the two second gears 330 meshing with each other, and a blowing assembly 370 is provided on one side of the inner wall of the mounting plate 100.

[0027] It should be noted that the photovoltaic panel cleaning robot with model number "JH-S2000" is manufactured by:

[0028] Wheeled design: adaptable to different terrains, such as the complex environment of distributed or centralized photovoltaic power plants.

[0029] Autonomous navigation system: It integrates GPS and lidar to achieve centimeter-level positioning accuracy and supports all-weather operation.

[0030] High-pressure water cleaning technology: A robotic arm equipped with a high-pressure nozzle is used to efficiently rinse the surface of photovoltaic panels to remove dirt.

[0031] Roller brush device: Some models use roller brushes to assist in cleaning and improve the removal of sand and dust.

[0032] When the cleaning robot is cleaning the photovoltaic panels, the cleaning mechanism 300 drives two first gears 320 and two second gears 330 to mesh with each other, causing two cleaning brushes 310 to rotate in opposite directions, which can clean the contaminants on the photovoltaic panels. The water flow sprayed from the water pipe 340 and the low-pressure nozzle 341 can rinse the contaminants. The first scraper 360 scrapes away water and impurities. The blowing component 370 blows air through the fan 372 to dry the residual moisture on the photovoltaic panels. The second scraper 376 can scrape away impurities. The cleaning mechanism 300 and the blowing component 370 work together to clean the photovoltaic panels without affecting the normal use of the cleaning robot.

[0033] like Figure 2 and Figure 3 As shown, the cleaning mechanism 300 also includes a water guide pipe 340 disposed on the other side of the inner wall of the mounting plate 100. One side of the water guide pipe 340 is connected to several evenly arranged low-pressure nozzles 341. A motor 350 is installed at the other end of the inner wall of the mounting plate 100. The output shaft of one end of the motor 350 is fixedly connected to one of the cleaning brushes 310. A first scraper 360 is fixedly connected to the other side of the bottom of the mounting plate 100. The first scraper 360 is disposed on the other side of another cleaning brush 310.

[0034] In this embodiment, the water pipe 340 sprays water at one end through the low-pressure nozzle 341 to rinse the surface of the photovoltaic panel. The motor 350 drives the first gear 320 at one end of one of the cleaning brushes 310 to rotate. One of the first gears 320 meshes with one of the second gears 330, which in turn drives the other first gear 320 to drive the other cleaning brush 310 to rotate synchronously in opposite directions. The two cleaning brushes 310 can clean the dust and contaminants on the photovoltaic panel. Then, the first scraper 360 scrapes away the contaminants and water flow on the photovoltaic panel, which can effectively clean the photovoltaic panel and improve the cleaning effect of the cleaning robot.

[0035] like Figure 4 and Figure 5 As shown, the purging assembly 370 includes multiple mounting slots 371 formed on the other side of the inner wall of the mounting plate 100. A fan 372 is installed on the inner wall of the mounting slot 371. The fan 372 is located on the other side of the first scraper 360. An air guide plate 373 is fixedly connected to the other side of the bottom of the mounting plate 100. An air outlet slot 374 is formed on the inner wall of the air guide plate 373. The air outlet slot 374 communicates with the mounting slot 371. Several uniformly arranged filters 375 are fixedly connected to the top of the mounting plate 100. The filters 375 are located above the fan 372. A second scraper 376 is provided on the other side of the air guide plate 373. The second scraper 376 is fixedly connected to the mounting plate 100.

[0036] In this embodiment, after the photovoltaic panel assembly is cleaned, the fan 372 in the mounting slot 371 blows out airflow, which blows along the air outlet slot 374 on the inner wall of the air guide plate 373 toward the surface of the photovoltaic panel assembly, so that the water stains remaining on the surface of the photovoltaic panel assembly are dried and dust is prevented from adhering to the photovoltaic panel assembly. The second scraper 376 moves with the mounting plate 100 to scrape the surface of the photovoltaic panel assembly a second time, which can improve the cleaning effect of the cleaning robot on the photovoltaic panel assembly.

[0037] Working principle: The mounting plate 100 drives the rotating wheel 200 to move along the outer wall of the photovoltaic panel through the control component. The water pipe 340 is connected to an external water source. Water is sprayed out through the low-pressure nozzle 341 to wash the impurities on the photovoltaic panel. The control drive motor 350 drives one of the cleaning brushes 310 to rotate. One of the cleaning brushes 310 drives one of the first gears 320 and one of the second gears 330 to rotate. One of the second gears 330 meshes with the other second gear 330. The rotation of the other second gear 330 and the other first gear 320 can drive another cleaning brush 310 to rotate in the opposite direction to clean the impurities on the photovoltaic panel. As the mounting plate 100 moves, it can drive the first scraper 360 to scrape away the water and impurities on the photovoltaic panel. The control component drives multiple fans 372 to rotate and blow out airflow. The airflow passes through the air outlet 374 on the air guide plate 373 and can blow the airflow onto the surface of the photovoltaic panel for drying. The second scraper 376 can scrape away the dust on the photovoltaic panel for a second time.

[0038] It should be noted that the motor 350 and fan 372 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the motor 350 and fan 372 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
