Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel manufacturing technology, and in particular to a surface cleaning device for the preparation of solar photovoltaic panels. Background Technology

[0002] Solar energy utilization is mainly based on two methods: photothermal conversion and photovoltaic conversion. Photothermal conversion converts solar radiation energy into heat energy through collectors for heating, hot water, and other applications. Photovoltaic conversion directly converts solar radiation energy into electrical energy through the photovoltaic effect, i.e., solar photovoltaic power generation. Photovoltaic conversion is currently the main form of solar energy utilization. In photovoltaic conversion, photovoltaic panels are used to complete the conversion of solar energy into electrical energy. The core of photovoltaic panels is semiconductor materials. When sunlight shines on the surface of photovoltaic panels, photon energy excites electrons in the semiconductor, generating electron-hole pairs. Under the action of an internal electric field, electrons and holes are separated and move in a direction, forming an electric current, thereby realizing the conversion of light energy into electrical energy. During the manufacturing and use of photovoltaic panels, their surfaces need to be cleaned to avoid dust accumulation, which would affect the conversion efficiency of the photovoltaic panels. As disclosed in publication number CN110193498A, a photovoltaic panel surface cleaning device is described. This device comprises photovoltaic panel strings arranged in a straight line. Its key feature is that a traveling device is horizontally mounted on one or more adjacent groups of photovoltaic panel strings. From front to back, the traveling device is sequentially equipped with a front-sweeping device, a scraping device, and a back-sweeping device that horizontally cover the surface of the photovoltaic panel strings. The traveling device is also equipped with a blower system and an automatic control system. The blower system is connected to the front-sweeping device, the back-sweeping device, and an auxiliary blowing system. The automatic control system is connected to the traveling device, the front-sweeping device, the scraping device, the back-sweeping device, and the blower system. This invention has a reasonable structure, stable operation, and high cleaning efficiency, and is used for the proper maintenance of user photovoltaic power stations, improving power generation efficiency.

[0003] For example, publication number CN107855297A describes a photovoltaic panel cleaning device, which includes a frame detachably mounted on a photovoltaic panel and a cleaning brush on the frame. The frame has sliders on opposite sides, and the two ends of the cleaning brush are fixed to the sliders. The cleaning brush forms an acute angle with the horizontal movement direction. The cleaning brush has multiple nozzles evenly distributed along its length, and the cleaning brush has pipes connecting the nozzles inside. The frame has a drive mechanism for driving the sliders to slide, and the frame also has grippers to fix the frame to the photovoltaic panel. This device can quickly and effectively remove stains from the surface of the photovoltaic panel, ensuring the power generation efficiency of the photovoltaic panel. However, while the above-mentioned technical solutions can achieve the cleaning function of photovoltaic panel surface, they are not suitable for cleaning large-scale photovoltaic panels. When cleaning a large number of photovoltaic panels, the cleaning efficiency is low. In addition, after cleaning, the user needs to manually clean the cleaning brush. The cleaning process needs to be paused, which affects the cleaning efficiency. Summary of the Invention

Support feet 2 are evenly fixedly installed on both sides of the lower end of the mounting frame 1, and soft pads are fixedly installed on the lower ends of each support foot 2. Supporting components 3 for receiving external photovoltaic panels are evenly installed inside the mounting frame 1. Moving components 4 for driving the photovoltaic panels are installed on both sides of the mounting frame 1. Mounting plates 5 are fixedly installed on both sides of the mounting frame 1. A rotating cleaning component 6 is installed on one mounting plate 5, located above the mounting frame 1. A vertical plate 7 is fixedly installed on the other mounting plate 5, and a cleaning component 8 for cleaning the rotating cleaning component 6 is installed on one side of the upper part of the vertical plate 7. In use, the support feet first... 2. Place this structure at the location of use, then adjust the traveling component 4 according to the size of the photovoltaic panel, and then place the photovoltaic panel on the receiving component 3. Driven by the traveling component 4, the photovoltaic panel moves on the receiving component 3 to complete the transportation of the photovoltaic panel. During the transportation of the photovoltaic panel, the rotating cleaning component 6 can clean the surface of the photovoltaic panel in the gap between the traveling components 4, and the cleaning component 8 can clean the rotating cleaning component 6 at regular intervals during the cleaning intervals. Therefore, it is not necessary to disassemble the cleaning roller 6010 for cleaning during the cleaning process, which improves the cleaning efficiency of the photovoltaic panel. In addition, the cleaning liquid can be evenly sprayed onto the cleaning roller 6010 during the cleaning process, thereby improving the cleaning effect of the photovoltaic panel surface.

[0018] As a technical optimization solution of the present invention, specifically as follows: Figure 2 and Figure 3 As shown, mounting grooves 9 are evenly provided on both sides of the interior of the mounting frame 1. The receiving component 3 includes a rotating bearing 301, which is fixedly installed in the mounting groove 9. A receiving roller 302 is fixedly installed inside the rotating bearing 301. The receiving rollers 302 are evenly arranged inside the mounting frame 1. A rubber pad 303 is fixedly installed on the outside of the receiving rollers 302. In use, the receiving rollers 302 can rotate in the mounting frame 1 through the rotating bearing 301, so that the photovoltaic panel can move on the receiving component 3 while receiving the photovoltaic panel.

[0019] As a technical optimization solution of the present invention, specifically as follows: Figure 4 and Figure 5 As shown, the traveling component 4 includes an L-shaped fixed plate 401 and a connecting plate 402. One end of the fixed plate 401 is fixedly installed on both ends of the upper side of the mounting frame 1, and the connecting plate 402 is fixedly installed on both ends of the upper side of the mounting frame 1. Connecting rods 403 are slidably engaged on both sides of the connecting plate 402. A screw 404 is installed in the middle of the connecting plate 402 and is threadedly connected to the connecting plate 402. A crank handle 405 is fixedly installed on one end of the screw 404. The traveling component 4 also includes an L-shaped movable plate 406, which is fixedly installed on the connecting rod 402. One end of the 03 and the middle of one side of the movable plate 406 are provided with a T-shaped circular groove. The other end of the screw 404 is rotatably engaged with the movable plate 406 through the T-shaped circular groove. In use, shaking the handle 405 can drive the screw 404 to rotate. Since the screw 404 is threadedly connected to the connecting plate 402, it can drive the movable plate 406 to move, thereby adjusting the distance between the movable plate 406 and the fixed plate 401 until it matches the size of the photovoltaic panel. In actual use, the photovoltaic panel is placed on the receiving roller 302 and then pushed under the roller 4010.

[0020] As a technical optimization solution of the present invention, specifically as follows: Figure 6As shown, hydraulic push rods 407 are evenly fixedly installed on the upper and lower ends of the fixed plate 401 and the movable plate 406. A mounting base 408 is fixedly installed on the lower end of the hydraulic push rod 407. A miniature hub motor 409 is fixedly installed on the mounting base 408. A roller 4010 is fixedly installed on the outside of the miniature hub motor 409. The roller 4010 is rotatably mounted on the mounting base 408, and a rubber anti-slip pad 4011 is fixedly installed on the outside of the roller 4010. In use, the hydraulic push rod 407 drives the mounting base 408 to move, which in turn drives the miniature hub motor 409 and the roller 4010 to move until the roller 4010 contacts the top of the photovoltaic panel. The miniature hub motor 409 drives the roller 4010 to rotate. Under the friction of the rubber anti-slip pad 4011, the photovoltaic panel can be moved on the receiving roller 302 to complete the conveying of the photovoltaic panel.

[0021] As a technical optimization solution of the present invention, specifically as follows: Figure 9 As shown, the rotary cleaning assembly 6 includes a vertical plate 601, which is fixedly installed on the upper end of a mounting plate 5 on one side. A reciprocating motor 602 is fixedly installed on one side of the vertical plate 601. A fixed cylinder 603 is fixedly installed at the output end of the reciprocating motor 602. Movable rods 604 are slidably engaged at both ends of the fixed cylinder 603. A partition 605 is fixedly installed inside the fixed cylinder 603. A self-locking motor 606 is fixedly installed on both sides of the partition 605. An adjusting threaded rod 607 is fixedly installed at the output end of the self-locking motor 606. The movable rod 604 is sleeved on the adjusting threaded rod 607. During use, the reciprocating motor 602 on the threaded rod 607 can drive the fixed cylinder 603 and the movable rod 604 to rotate, thereby driving the cleaning roller 6010 to adjust its position. This allows the cleaning roller 6010 to switch between cleaning the photovoltaic panel and self-cleaning states. During the switching process, the self-locking motor 606 can drive the adjusting threaded rod 607 to rotate, thereby driving the movable rod 604 to move in the fixed cylinder 603, which in turn drives the cleaning roller 6010 to move. This facilitates the cleaning roller 6010 entering the cleaning box 801 and making it easier to contact the surface of the photovoltaic panel.

[0022] As a technical optimization solution of the present invention, specifically as follows: Figure 8 As shown, a control motor 608 is fixedly installed on one side of one end of the movable rod 604. A rotating shaft 609 is fixedly installed on the output end of the control motor 608. One end of the rotating shaft 609 is rotatably engaged with the movable rod 604. A cleaning roller 6010 is fixedly installed on the rotating shaft 609. The cleaning roller 6010 is located on one side of the movable rod 604. When the cleaning roller 6010 cleans the surface of the photovoltaic panel, the control motor 608 can drive the rotating shaft 609 to rotate, thereby driving the cleaning roller 6010 to rotate, so that the cleaning roller 6010 can complete the cleaning of the photovoltaic panel surface.

[0023] As a technical optimization solution of the present invention, specifically as follows: Figure 10As shown, the cleaning assembly 8 includes a cleaning box 801, which is fixedly installed on the upper side of the vertical plate 7 and located above the mounting frame 1. The side of the cleaning box 801 has an inlet / outlet groove 802 for the rotating shaft 609 and the cleaning roller 6010 to enter and exit. A cleaning brush 803 for cleaning the cleaning roller 6010 is fixedly installed inside the lower end of the cleaning box 801. A liquid storage box 804 is fixedly installed inside the upper end of the cleaning box 801. An inlet pipe 805 is fixedly installed at the upper end of the liquid storage box 804, connecting to the liquid storage box 804. The other end of the inlet pipe 805 passes through the cleaning box 801 and connects to an external cleaning liquid tank. Spray nozzles 806 are evenly fixedly installed at the lower end of the liquid storage box 804, connecting to the liquid storage box 804. The exterior of the cleaning box 801... A liquid outlet pipe 807 is fixedly installed on one side of the lower end. One end of the liquid outlet pipe 807 is connected to the inside of the cleaning box 801, and the other end of the liquid outlet pipe 807 is connected to the external waste liquid tank. When the cleaning roller 6010 performs self-cleaning, the control motor 608 drives the rotating shaft 609 and the cleaning roller 6010 to rotate. At this time, the cleaning roller 6010 contacts the cleaning brush 803, so that the impurities on the cleaning roller 6010 can be cleaned by the cleaning brush 803. At the same time, the cleaning liquid can enter the storage box 804 through the liquid inlet pipe 805, and then be sprayed onto the cleaning roller 6010 through the nozzle 806, further improving the cleaning effect of the cleaning roller 6010. It can also make the cleaning liquid sprayed on the cleaning roller 6010, which can improve the cleaning effect when cleaning the surface of the photovoltaic panel. The cleaning liquid after cleaning can be discharged through the liquid outlet pipe 807.
