Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of photovoltaic panel cleaning devices, specifically a rapid cleaning device for photovoltaic modules. Background Technology
[0002] As the scale of photovoltaic power plant construction continues to expand, the problem of surface pollution of photovoltaic modules is becoming increasingly prominent. Dust, sand, bird droppings, fallen leaves and other pollutants adhere to the surface of the modules for a long time, which will significantly reduce light absorption efficiency and cause power generation loss. Therefore, it is necessary to clean the photovoltaic modules regularly.
[0003] Currently, the main methods for cleaning photovoltaic modules include manual cleaning and automatic cleaning systems. Manual cleaning is highly flexible but inefficient and labor-intensive. While fixed automatic cleaning systems can achieve automated operation, they require an independent cleaning unit for each row of photovoltaic arrays, resulting in large equipment investment, complex wiring, and difficult maintenance. They are particularly unsuitable for distributed or non-standard photovoltaic systems. Utility Model Content

[0031] Example 1
[0032] As attached Figures 1 to 8 The photovoltaic module rapid cleaning device shown includes: a support frame 1, a plurality of mounting brackets 11 fixedly installed on the top of the support frame 1, a plurality of photovoltaic panels 12 fixedly installed on the top of the plurality of mounting brackets 11, two guide rails 13 fixedly installed between the plurality of mounting brackets 11, and a cleaning mechanism, which is disposed on the two guide rails 13 and is used to clean debris from the surface of the photovoltaic panels 12.
[0033] Specifically: During the installation of photovoltaic panels 12, support frame 1 is installed on the ground, and mounting frame 11 is installed on support frame 1. Multiple sets of photovoltaic panels 12 are installed on mounting frame 11. At the same time, two guide rails 13 are pre-installed on mounting frame 11. When cleaning photovoltaic panels 12, cleaning fluid is sprayed onto photovoltaic panels 12. Then, the cleaning mechanism is installed on the two guide rails 13. The cleaning mechanism is activated and moves from one end of the two guide rails 13 to the other end and stops working. While moving, the surface of photovoltaic panels 12 is cleaned, removing dust and debris. After cleaning, it is rinsed with clean water. After rinsing, the cleaning mechanism is activated again, causing it to move in the opposite direction to clean photovoltaic panels 12 again and scrape off water stains. This removes the wastewater from the second cleaning. Then, the cleaning mechanism is removed and placed on other photovoltaic panels 12. Therefore, only one cleaning mechanism is needed to complete the cleaning of the photovoltaic array group.
[0034] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 8 As shown below, see details:
[0035] The cleaning mechanism includes: a housing 2, a groove 21, a water-retaining cover 22, a rotating rod 23, a cleaning roller brush 24, and a rubber scraper 25. The housing 2 is located between two guide rails 13. A groove 21 is formed at the bottom of the housing 2. A water-retaining cover 22 is fixedly installed near the edge of the groove 21. Rotating rods 23 are rotatably connected to the inner walls of the water-retaining cover 22 on opposite sides. The rotating rods 23 have a hexagonal structure at their center. A cleaning roller brush 24 is fixedly installed on the outside of the rotating rods 23. A rubber scraper 25 is fixedly installed on one side of the bottom of the housing 2. Two symmetrically arranged connecting blocks 3 are fixedly installed at the top inside the housing 2, and the two connecting blocks 3 are respectively connected to the top inside the housing 2. A drive rod 31 is rotatably connected between the connecting blocks 3. Drive gears 32 are fixedly connected to the opposite ends of the drive rod 31. Drive gears 33 are fixedly installed at the opposite ends of the rotating rod 23 into the housing 2. Drive gears 32 and driven gears 33 on the same side are meshed together. A mounting frame 4 is fixedly installed at the top near the middle of the housing 2. A stepper motor 41 is fixedly installed on the mounting frame 4. The drive shaft at the bottom of the stepper motor 41 extends to the outside of the mounting frame 4 and is fixedly connected to a bevel gear a42. A bevel gear b43 is fixedly connected to the outside of the drive rod 31 at the position opposite to the bevel gear a42. The bevel gear a42 and the bevel gear b43 are meshed together.
[0036] During cleaning, the stepper motor 41 is activated via the control panel on the top of the housing 2. The housing 2 contains a battery that provides power, which can be charged via a charging cable. Once activated, the stepper motor 41 drives the bevel gear a42 to rotate. The control panel on the top of the housing 2 allows switching between forward and reverse rotation modes for the stepper motor 41. The bevel gear a42 meshes with the bevel gear b43, which in turn drives the drive rod 31 to rotate. The drive rod 31 then drives the drive gears 32 at both ends to rotate. The drive gears 32 mesh with the driven gears 33, causing the driven gears 33 to rotate relative to each other. This, in turn, drives the rotating rod 23 to rotate the cleaning roller brush 24. The rotating cleaning roller brush 24 continuously scrubs the surface of the photovoltaic panel 12. As the housing 2 moves, the rubber scraper 25 cleans the surface of the photovoltaic panel 12. The water stains on the surface are scraped off, and the large gear driving gear 32 meshes with the small gear driven gear 33, thereby increasing the rotation speed of the cleaning roller brush 24. The rotation direction of the cleaning roller brush 24 is opposite to the movement direction of the housing 2, which generates a certain resistance to the cleaning roller brush 24, so that the cleaning roller brush 24 can better clean the impurities on the surface of the photovoltaic panel 12. Since the bristles of the cleaning roller brush 24 are relatively soft, they will not block the movement of the housing 2. After the first cleaning is completed, the housing 2 is turned 180 degrees so that the rubber scraper 25 is behind the cleaning roller brush 24. The rubber scraper 25, which is located behind the path of the cleaning roller brush 24, can scrape off the sewage generated during the brushing of the cleaning roller brush 24, so that the surface of the photovoltaic panel 12 dries quickly. When cleaning the next photovoltaic array, the stains on the cleaning roller brush 24 are rinsed with clean water.
[0037] In a preferred embodiment, two symmetrically arranged sliders 5 are fixedly installed at the bottom of the housing 2. The sliders 5 are slidably connected to the guide rail 13. The top of the guide rail 13 is provided with guide grooves 51. Two rollers 52 are rotatably connected between the inner walls of the sliders 5 on opposite sides. Pressure sensors 53 are fixedly installed at opposite ends of the sliders 5. Multiple balls 54 are provided on opposite sides of the sliders 5. Protective covers 6 are fixedly installed at opposite ends of the housing 2. One end of the drive shaft of the roller 52 extends into the interior of the adjacent protective cover 6 and is fixedly installed with a drive sprocket 61. The rotating rod 23 extends into the interior of the two protective covers 6 at opposite ends and is fixedly connected with driven sprockets 62. A chain 63 connects the drive sprocket 61 and the driven sprocket 62 on the same side.
[0038] Furthermore, during the installation of the cleaning mechanism, the two sliders 5 are aligned with the two guide rails 13 and placed on them. The rollers 52 are located in the guide grooves 51. The rollers 52 and the guide grooves 51 support and restrict the sliders 5, preventing them from derailing from the guide rails 13. The balls 54 on the inner wall of the sliders 5 are used for support, preventing the sides of the sliders 5 and rollers 52 from contacting the guide rails 13 and guide grooves 51. If there are any debris in the guide grooves 51, they need to be cleaned out in advance. When the drive rod 31 rotates, it simultaneously drives the drive sprocket 61 to rotate. The rotation of the drive sprocket 61 drives the driven sprocket 62 to rotate synchronously through the chain 63. The protective cover 6 protects the drive sprocket 61 and the driven sprocket 62. The driven sprocket 62 provides protection by enclosing the drive sprocket 61. The driven sprocket 62 and the driven sprocket 62 are of the same specifications. When the driven sprocket 62 rotates, it drives the roller 52 to rotate. The roller 52 rolls inside the guide groove 51, thereby driving the slider 5 to move the housing 2. The stepper motor 41 rotates at a relatively slow speed, so that the housing 2 moves slowly, allowing sufficient cleaning time for the surface of the photovoltaic panel 12. When the slider 5 moves to one end of the guide rail 13, the pressure sensor 53 abuts against the limit block of the guide rail 13. The pressure sensor 53 detects the pressure and controls the stepper motor 41 to stop working. The pressure sensor 53 and the stepper motor 41 are electrically connected.
[0039] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
