[0034] Implementation Method 1
[0035] Reference Figures 1 to 2 This embodiment is an optional embodiment of this application, which discloses a photovoltaic panel cleaning system, including a frame 1. The frame 1 has a long strip-shaped ring structure to adapt to the shape of the solar photovoltaic panel, while avoiding the frame 1 from shading the solar photovoltaic panel.
[0036] The frame 1 is also equipped with a spray system and a support frame 12. The spray system includes a water tank 6, a spray pipe 7, and a spray pump 8. The inlet end of the spray pump 8 is connected to the water tank 6, and the outlet end of the spray pump 8 is connected to the spray pipe 7. The support frame 12 is arranged parallel to the length of the frame 1. Along the axial direction of the support frame 12, a plurality of brackets 13 are provided on the support rod. The spray pipe 7 is arranged along the axial direction of the support frame 12 and is respectively connected to each of the brackets 13.
[0037] Along the axial direction of the spray pipe 7, a plurality of spray nozzles 9 are provided on the spray pipe 7, each of the spray nozzles 9 facing downward. It should be noted that in engineering practice, solar photovoltaic panels are generally set at a certain tilt angle, and the spray direction of the spray nozzles 9 is directly facing the top of the upturned end of each solar photovoltaic panel, so that the water flow is automatically spread to cover the entire photovoltaic panel by gravity.
[0038] Reference Figure 3 Furthermore, along the axial direction of the spray pipe 7, a number of three-way pipes 10 are provided on the spray pipe 7, and each of the three-way pipes 10 is provided with a duckbill nozzle 11 for spraying cleaning water. The spray direction of the duckbill nozzle 11 is directly facing the top of the upturned end of each solar photovoltaic panel.
[0039] The use of duckbill nozzles 11 enables the cleaning water to be sprayed out in a planar structure, which can effectively increase the coverage area of each nozzle and ensure that the spraying device can effectively cover the entire area of the solar photovoltaic panel, thus improving the cleaning quality.
[0040] Along the length of the frame 1, a slide rail 26 is provided on both sides of the frame 1. The two slide rails 26 are parallel to each other, and at least two sliders 27 are slidably arranged on each of the two slide rails 26. The frame 1 is also provided with a slide block 2. The slide block 2 is a flat plate. The two sides of the slide block 2 are respectively connected to the sliders 27 on the same side, thereby realizing the sliding connection between the slide rail 26 and the frame 1.
[0041] The cleaning system also includes a drive module, which includes a drive motor 14 and a drive rack 15. The drive rack 15 is mounted on the frame 1, and the drive motor 14 is mounted on the slide 2. A drive gear is also mounted on the output shaft of the drive motor 14, and the drive gear meshes with the drive rack 15.
[0042] Furthermore, a support bar 16 is also provided on the frame 1. The support bar 16 is arranged along the sliding direction of the slide block 2, and the drive rack 15 is installed on the top surface of the support bar 16. The support bar 16 allows for convenient adjustment of the installation height of the drive rack 15.
[0043] Meanwhile, a detection module is also provided on the side of the support bar 16. The detection module includes several mounting seats 17. Each mounting seat 17 is an L-shaped mounting plate. Each mounting seat 17 is provided with a light spot sensor. At the same time, several connecting screws are also provided on the support bar 16. Each connecting screw is connected to each mounting plate, thereby arranging several photoelectric sensors 18 sequentially along the running trajectory of the slide block 2.
[0044] The photoelectric sensor 18 is preferably a slotted photoelectric sensor 18. A baffle 19 is also provided on the slide 2. The baffle 19 cooperates with the photoelectric sensor 18 to send a control signal.
[0045] Along the axial direction of the spray pipe 7, a plurality of regulating valves 20 are provided on the spray pipe 7, and each of the regulating valves 20 and each of the photoelectric sensors 18 are electrically connected to the controller 5.
[0046] In use, the spray pipe 7 is divided into several sections by the regulating valve 20, and the position of the slide 2 is detected by the photoelectric sensor 18. The regulating valve 20 will be closed if the distance from the slide 2 exceeds the set value. Thus, according to the position of the slide 2, each regulating valve 20 is controlled to open in sequence to avoid the regulating valve 20 opening too early and causing water waste.
[0047] It should be noted that once the regulating valve 20 is opened during the cleaning process, it will not be closed again. Instead, all regulating valves 20 will be closed at the same time after the cleaning process is completely finished.
[0048] Furthermore, a rotating shaft is rotatably mounted on the slide 2, and a cleaning roller 3 is mounted on the rotating shaft. A rotary motor 4 is also mounted on the slide 2. The output shaft of the rotary motor 4 is poweredly connected to the rotating shaft through a bevel gear or a coupling, thereby driving the cleaning roller 3 to rotate.
[0049] Meanwhile, a protective cover 25 is also provided on the slide 2, which encloses the entire cleaning roller 3 inside, that is, the protective cover 25 encloses the area above the cleaning roller 3; the slide 2 is provided with a through hole, and the bottom of the cleaning roller 3 passes through the through hole and is attached to the solar photovoltaic panel.
[0050] The protective cover 25 can seal the upper side of the cleaning drum 3, preventing the wastewater from being thrown onto the cleaned solar photovoltaic panels during the rotation of the cleaning drum 3, thus improving the cleaning quality.
[0051] A rotating frame 21 is also hinged to the slide block 2. A water-absorbing roller 22 is rotatably mounted on the rotating frame 21, and a sponge 23 is sleeved on the roller. An electric push rod 24 is also hinged to the slide block 2, and the working end of the electric push rod 24 is hinged to the rotating frame 21.
[0052] Furthermore, the cleaning system also includes a controller 5, which includes an industrial control computer and a PLC. The industrial control computer is electrically connected to the PLC, and the PLC is electrically connected to the rotary motor 4, the drive motor 14, the spray pump 8, each regulating valve 20 and each photoelectric sensor 18.
[0053] Furthermore, the length of the frame 1 must exceed the laying length of the photovoltaic panel. That is, along the length direction of the frame 1, a sufficient stopping area is reserved at any end of the frame 1 for placing the slide 2, so as to avoid the slide 2 always being directly above the solar photovoltaic panel and avoid shading the solar photovoltaic panel.
[0054] When the cleaning system described in this application is used, cleaning water is first sprayed onto the surface of the photovoltaic panel through a spray system. Then, the sliding block is controlled by a drive motor. While the sliding block is sliding, the cleaning drum is rotated by a rotary motor. The rotating cleaning drum achieves rapid cleaning of the photovoltaic panel. Since the photovoltaic panel is tilted, the wastewater after cleaning will automatically flow to the ground.
[0055] Compared with the prior art, this application can clean each solar photovoltaic panel separately and realizes the fully automated operation of the cleaning process, which effectively improves the cleaning efficiency of solar photovoltaic panels.
[0056] Secondly, this application can promptly clean the dust accumulated on the surface of solar photovoltaic panels, thereby ensuring the cleanliness of the solar photovoltaic panels and guaranteeing power generation.
[0057] Compared with existing technologies, the cleaning system described in this application has a simpler structure, which effectively improves the reliability and stability of the equipment.
[0058] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
