Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panels, specifically relating to roller brush components and photovoltaic cleaning robots. Background Technology

[0002] Solar energy, as a clean and renewable energy source, has gradually become an important component of global energy structure optimization due to its abundant resources and good environmental benefits. Against this backdrop, photovoltaic (PV) power generation technology has been widely applied, especially occupying a significant position in renewable energy power generation systems. However, large-scale PV power plants are generally deployed in arid and low-rainfall areas. Without prolonged cleaning, large amounts of dust in the air accumulate on the surface of the PV modules, significantly affecting the energy conversion of the PV power plant and ultimately impacting the power generation efficiency and economic benefits of the entire PV system.

[0003] In existing technologies, cleaning photovoltaic panels typically involves using a roller brush that contacts the panel, with the brush and a drive motor connected via gears. When the drive motor operates, it rotates the roller brush. The rolling brush then contacts the photovoltaic panel, thus cleaning it.

[0004] However, when using a roller brush to clean photovoltaic panels, the other end of the brush is prone to wobbling or shaking because it is usually driven from one end. This ultimately leads to a decrease in the cleaning effect of the roller brush. Utility Model Content

[0005] This utility model provides a roller brush assembly and a photovoltaic cleaning robot, the purpose of which is to solve the problem that the cleaning effect of the roller brush is affected by the single-end drive of the roller brush rotation.

[0006] To achieve the above objectives, this utility model provides a roller brush assembly, including...

[0007] Roller brush;

[0008] A frame, wherein the roller brush is rotatably mounted on the frame; and

[0009] The drive motor is mounted on the frame, and there are two drive motors, which are respectively connected to the two ends of the roller brush.

[0010] In this design, both ends of the roller brush are connected to two drive motors, meaning the roller brush is driven to rotate by the cooperation of the two drive motors. This design avoids wobbling or swinging at one end of the roller brush, overcoming the shortcomings of existing technologies.

[0011] Preferably, in order to improve the transmission stability between the drive motor and the roller brush, the roller brush and the drive motor are driven by gear meshing in this solution.

[0012] This solution uses gear meshing transmission between the drive motor and the roller brush. Compared to other transmission methods, gear meshing transmission results in a more compact structure and higher connection stability between the drive motor and the roller brush.

[0013] Preferably, the roller brush and the drive motor are connected by a bevel gear transmission in this solution.

[0014] This solution uses bevel gear transmission, which not only enables power transmission between two intersecting shafts, but also has high transmission accuracy and stability. It can effectively reduce the problem of brush tilting caused by transmission errors, and further ensure the efficiency and quality of cleaning operations.

[0015] Preferably, when cleaning the photovoltaic panel using a roller brush, the roller brush separates impurities from the photovoltaic panel, and the impurities then fall back onto the photovoltaic panel surface due to gravity. Therefore, to solve the above problem, this solution also includes an air jet module, which is disposed on the frame and faces the roller brush.

[0016] In this design, when the roller brush removes impurities, the impurities are lifted up. Then, the air jet module operates, releasing airflow to keep the lifted impurities away from the photovoltaic panel, preventing them from falling back onto the panel and causing secondary pollution, thus improving the cleaning effect of the photovoltaic panel.

[0017] Preferably, in order to spray air onto the roller brush, the jet module of this solution includes an air nozzle and a gas supply unit, the air nozzle and the gas supply unit are connected, the air nozzle is positioned facing the roller brush, and the air nozzle is used to release airflow onto the roller brush.

[0018] This solution supplies gas via a gas supply unit, and the airflow is then ejected from a nozzle. Because the nozzle is positioned towards the roller brush, the airflow released from the nozzle can disperse impurities, preventing them from falling back onto the photovoltaic panel.

[0019] Preferably, to prevent impurities from falling onto the surface of the photovoltaic panel after cleaning, the present solution provides at least two air nozzles, each with a different airflow release direction; the jet module also includes an adjustment unit for adjusting the connection status between the air nozzle and the gas supplier.

[0020] This solution uses air nozzles that can release airflow in different directions. When in different working positions, these nozzles can disperse impurities in different directions, preventing them from falling onto the already cleaned photovoltaic panels.

[0021] Preferably, the air nozzles in this solution are configured as two, with the two air nozzles facing to the sides respectively.

[0022] The second aspect of this utility model provides a photovoltaic cleaning robot, including the aforementioned roller brush assembly and drive module, wherein the roller brush assembly is connected to the drive module, and the drive module is used to drive the roller brush assembly to move.

[0023] This solution uses a moving module to move the roller brush assembly, allowing the roller brush assembly to move to different positions on the photovoltaic panel, thereby achieving cleaning of different locations on the photovoltaic panel.

[0024] Preferably, in order to ensure the cleanliness of the photovoltaic panel and facilitate the movement of the photovoltaic cleaning robot, the drive module of this solution is a mobile vehicle, which is used to move on the surface of the photovoltaic panel.

[0025] Preferably, since some photovoltaic panels are tilted, in order to ensure that the moving vehicle is stable on the tilted photovoltaic panels, the driving module of this solution includes an adsorption unit, which is used to adsorb the photovoltaic panels.

[0026] This solution uses an adsorption unit to attach the mobile vehicle to the photovoltaic panel, which keeps the vehicle stable and prevents it from falling off.

[0027] The beneficial effects of this invention are as follows: In this design, both ends of the roller brush are connected to two drive motors, meaning the roller brush is driven to rotate by the cooperation of the two drive motors. This design avoids wobbling or swinging at one end of the roller brush, making the roller brush more stable and ensuring better cleaning results. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0037] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0038] Example 1

[0039] The basics are as follows: Figure 1 As shown, a roller brush assembly is designed to clean photovoltaic panels. Impurities on the photovoltaic panels can include dust, leaves, and bird droppings.

[0040] The roller brush assembly of this embodiment includes a frame 1, a roller brush 2, and a drive motor 3. The frame 1 is U-shaped, and a connecting part is provided at the rear end of the frame 1. In this embodiment, the roller brush 2 is preferably a nylon roller brush. The roller brush 2 is mounted on the frame 1, and both ends of the roller brush 2 are rotatably connected to the frame 1 via rotating shafts. Simultaneously, two drive motors 3 are provided, each located at one end of the roller brush 2. The output shaft of the drive motor 3 is equipped with an output gear, and a transmission gear is fitted onto the rotating shaft of the roller brush 2. The output gear and the transmission gear are in a meshing transmission state. In this embodiment, both the output gear and the transmission gear are preferably bevel gears.

[0041] Taking one application scenario as an example: When the drive motor 3 is working, both ends of the drive motor 3 drive the brush to rotate through gears. The drive motors 3 at both ends restrict the two ends of the roller brush 2, preventing the roller brush 2 from shaking or swaying, thus improving the cleaning effect of the roller brush 2.

[0042] It should be noted that in this embodiment, transmission is achieved through gear meshing. However, in some other embodiments, the drive motor 3 can drive the roller brush 2 to rotate in various ways. For example, the roller brush 2 can be driven to rotate by belt transmission, chain transmission, or the output shaft of the drive motor 3 can be directly connected to the roller brush 2 to achieve the same effect.

[0043] Example 2

[0044] This embodiment improves upon embodiment 1. When using the roller brush 2 to clean the photovoltaic panel, the roller brush 2 separates impurities from the photovoltaic panel, but the impurities will then fall back onto the photovoltaic panel surface due to gravity, ultimately resulting in poor cleaning performance. To solve the above problem, this embodiment also includes an air jet module 4. The air jet module 4 can disperse the air-blown impurities, preventing them from falling back onto the photovoltaic panel surface and improving the cleaning effect of the photovoltaic panel.

[0045] In this embodiment, the jet module 4 is mounted on the frame 1, such as... Figure 2 and Figure 3 As shown, the jet module 4 includes a nozzle 41 and a gas supply unit 42. The nozzle 41 is generally flat and is mounted on the frame 1 using fasteners. An air outlet, which is in a straight line shape, is located at the front end of the nozzle 41. The air outlet of the nozzle 41 faces the roller brush 2. The nozzle 41 has an internal air duct, with the inlet of the duct serving as the air inlet. The gas supply unit 42, which can be a blower or a compressed air cylinder, is mounted at the air inlet using fasteners.

[0046] Taking one application scenario as an example: When the roller brush 2 rotates, it lifts up impurities on the photovoltaic panel. Then, the gas supply unit 42 delivers airflow into the air nozzle 41. The airflow flows along the inside of the air nozzle 41 and is finally released from the air outlet at the front end of the air nozzle 41. The airflow disperses the impurities lifted up by the roller brush 2 towards the front end, preventing the impurities from falling onto the already cleaned photovoltaic panel.

[0047] Example 3

[0048] The difference between this embodiment and embodiment 1 is that, in this embodiment, the jet module 4 is preferably a fan, which is directly installed on the frame 1, and the air outlet of the fan is inclined to the roller brush 2.

[0049] To illustrate with an example application scenario: When the roller brush 2 rotates, it lifts up the impurities on the photovoltaic panel. Then, the fan operates and blows air to one side of the roller brush 2, dispersing the impurities lifted by the roller brush 2 and preventing them from falling onto the area cleaned by the roller brush 2.

[0050] Example 4

[0051] The difference between this embodiment and Embodiment 1 lies in the structure of the jet module 4, such as... Figure 4 and Figure 5 As shown. In this embodiment, at least two air nozzles 41 are preferably provided, and more preferably two. Both air nozzles 41 are mounted on the frame 1, and the two air nozzles 41 face the left front side or right front side of the roller brush 2, respectively. The two air nozzles 41 are connected to the gas supply unit 42 through pipes. The gas supply unit 42 can be a blower. At the same time, the jet module 4 in this embodiment also includes an adjustment unit, which is preferably a three-way valve. The gas supply unit 42 and the air nozzles 41 are connected through the three-way valve. The three-way valve can adjust the connection state between the gas supply unit 42 and the air nozzles 41.

[0052] For example, in one application scenario: when the roller brush 2 cleans the photovoltaic panel in different directions, the gas supply device 42 is connected to different air nozzles 41 by adjusting the three-way valve, so that the airflow blows the impurities in different directions, preventing the impurities from falling onto the photovoltaic panel that has already been cleaned.

[0053] It should be noted that, in this embodiment, two air nozzles 41 are preferably provided. However, in some other embodiments, three, four, or five air nozzles 41 may also be provided. The air outlets of different air nozzles 41 face different directions. Of course, in order to ensure the supply of airflow, the number of gas suppliers 42 may be appropriately increased according to the number of air nozzles 41.

[0054] It should be noted that in this embodiment, the two air nozzles 41 are preferably set to face the left front side and the right front side. However, in some other embodiments, the two air nozzles 41 can also be set at the end of the roller brush 2, with the two air nozzles 41 facing the left and right sides respectively.

[0056] This embodiment provides a photovoltaic cleaning robot, such as Figure 6 As shown, it includes a roller brush assembly and a drive module according to Embodiment 1, Embodiment 2, Embodiment 3 or Embodiment 4.

[0057] In this embodiment, the driving module is preferably a mobile vehicle 5, which can move on the surface of the photovoltaic panel. The mobile vehicle 5 in this embodiment includes a frame 51 and a driving unit 52, such as... Figure 7 As shown, the frame 51 is rectangular, and its front end is fixedly connected to the frame 1 in the roller brush assembly. In practice, this connection can be achieved by configuring fasteners. Drive units 52 are configured on both the left and right sides of the frame 51. Each drive unit 52 is a synchronous pulley set, which powers the moving vehicle 5 to move.

[0058] In this embodiment, the frame 51 also includes an adsorption unit 53. The adsorption unit 53 is used to adsorb the photovoltaic panel, making the photovoltaic cleaning robot more stable when moving on the photovoltaic panel. Multiple adsorption units 53 can be provided in this embodiment, such as two, three, or four. The adsorption unit 53 can adopt a negative pressure adsorption module as used in the prior art. The adsorption units 53 are disposed on the frame 51 and arranged in a straight line.
