DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 9 The present invention provides two technical solutions, which specifically include the following embodiments: Example 1: Reference Figure 1-Figure 3 A novel photovoltaic panel cleaning device comprises a machine body 1, a conveyor belt 2 and an output belt 3 are respectively arranged on both sides of the machine body 1, which are used to convey the photovoltaic panel body 4, two sets of conveyor shafts 6 are rotatably connected inside the machine body 1, and the installation positions of the two sets of conveyor shafts 6 are respectively located at the ends of the conveyor belt 2 and the output belt 3, and multiple clamping conveying rings 7 are fixedly installed on the outside of the two sets of conveyor shafts 6, which are used to clamp and push the photovoltaic panel body 4, and the conveyor belt 2 and the output belt 3 are both existing devices. As the conveyor belt 2 runs, the photovoltaic panel body 4 above can be conveyed until the end of the photovoltaic panel body 4 moves between a set of conveyor shafts 6, at which time the photovoltaic panel body 4 can be clamped by the clamping conveying rings 7 installed on the outside of the two conveyor shafts 6, and the clamping conveying rings 7 are driven to run by the reverse rotation of the two conveyor shafts 6, so as to convey the photovoltaic panel body 4 to the inside of the machine body 1; refer to Figure 1-Figure 9A plurality of cleaning shafts 8 are provided between the two groups of conveying shafts 6, and the plurality of cleaning shafts 8 are respectively located at the upper and lower sides of the photovoltaic panel body 4, and a plurality of fixing rings 9 are fixed on the outer sides of the plurality of cleaning shafts 8, and a plurality of elastic cleaning brushes 901 are fixedly installed on the outer sides of the fixing rings 9, and the elastic cleaning brushes 901 are used to brush the conveyed photovoltaic panel body 4 as the cleaning shafts 8 rotate. When the end of the conveyed photovoltaic panel body 4 enters between the two cleaning shafts 8, as the cleaning shafts 8 run, the plurality of fixing rings 9 and the elastic cleaning brush 901 on the outer sides can be driven to run, so as to realize the brushing treatment of both sides of the photovoltaic panel body 4; Furthermore, two fixed racks 10 are fixedly installed inside the machine body 1. The installation positions of the two fixed racks 10 are respectively located at the upper and lower sides of the photovoltaic panel body 4. A plurality of high-pressure flushing terminals 1001 are fixed on one side of the two fixed racks 10 close to the photovoltaic panel body 4. The high-pressure flushing terminals 1001 are used to spray cleaning water to the photovoltaic panel body 4 to achieve a flushing operation on the photovoltaic panel body 4. The photovoltaic panel body 4 after being brushed by the elastic cleaning brush 901 can enter between the fixed racks 10. As the cleaning water passes through the fixed racks 10 and the plurality of high-pressure flushing terminals 1001 and is sprayed to the photovoltaic panel body 4, a flushing operation is achieved until the photovoltaic panel body 4 contacts the running output belt 3 and is output, completing the cleaning process. A pump is provided on the outside of the machine body 1. A connecting pipe is provided between the two fixed racks 10 and the output end of the pump. The pump is an existing device and is not shown in the figure. For further reference, Figure 4-Figure 9 Two side sealing plates 13 are fixedly installed inside the machine body 1. The two side sealing plates 13 are respectively located between the two groups of conveying shafts 6 and the cleaning shaft rod 8. The two side sealing plates 13 are symmetrically provided with rectangular notches inside for the photovoltaic panel body 4 to pass through. Through the arrangement of the two side sealing plates 13, when the photovoltaic panel body 4 is being conveyed and cleaned, the end can pass through the corresponding rectangular notch until the cleaning is completed and the output is realized. Through the cooperation of the side sealing plates 13, the muddy water splashed during the cleaning process can be blocked, thereby ensuring the subsequent cleaning effect and the convenience of equipment maintenance. Furthermore, a rotating shaft 1301 is fixedly installed inside the rectangular notch, and a plurality of sealing baffles 14 are fixedly sleeved on the outer side of the rotating shaft 1301. A plurality of torsion springs 1302 adapted to the sealing baffles 14 are sleeved on the outer side of the rotating shaft 1301, which are used to drive the sealing baffles 14 to reset. During the transportation and cleaning process of the photovoltaic panel body 4, as the end of the photovoltaic panel body 4 can enter the corresponding rectangular notch, it can contact the corresponding sealing baffle 14, so that the sealing baffle 14 is forced to rotate along the rotating shaft 1301. At this time, the torsion spring 1302 is stressed. When the photovoltaic panel body 4 is separated from the rectangular notch, the sealing baffle 14 can be forced to rotate and reset along the rotating shaft 1301 through the cooperation of the torsion spring 1302, thereby further improving the sealing effect of the side sealing plate 13. A concave transmission frame 15 is installed inside the body 1 for sliding up and down, and cleaning scrapers 1501 are fixedly installed at both ends of the concave transmission frame 15. The two cleaning scrapers 1501 are respectively fitted with the corresponding side sealing plates 13 to scrape off the mud and water splashed on the surface of the side sealing plates 13. A hydraulic cylinder 5 is fixedly installed on the inner top surface of the body 1, and the piston end of the hydraulic cylinder 5 is fixedly connected to the concave transmission frame 15 to drive the concave transmission frame 15 to slide up and down inside the body 1. As the cleaned photovoltaic panel body 4 is continuously transported and separated from the rectangular notch, the concave transmission frame 15 can be driven to slide down by the operation of the hydraulic cylinder 5, so that the cleaning scrapers 1501 on both sides can move down along the side sealing plates 13 to scrape off the mud, water, soil, etc. attached to the surface of the side sealing plates 13, thereby ensuring the subsequent cleaning effect of the photovoltaic panel body 4 and improving the maintenance convenience of the equipment. Furthermore, a wastewater discharge rack 11 is fixedly installed at the bottom of the inner side of the machine body 1, and a drainage slot 1101 is opened on the side of the wastewater discharge rack 11 for discharging the collected wastewater. The wastewater discharge rack 11 is an open type, and a pull-out sealing plate 12 is slidably inserted into one side of the opening, and a pull plate 1201 is fixedly installed on the outer side of the pull-out sealing plate 12. During the flushing process, the wastewater and the soil mixed in the wastewater can flow downward into the wastewater discharge rack 11, and then be discharged through the drainage slot 1101. Figure 6 The pull-out sealing plate 12 is inserted into the wastewater discharge rack 11. When the mud settles, it can fall on the pull-out sealing plate 12, and the sewage can be discharged through the drainage groove 1101; A filter plate 1102 is provided inside the drainage notch 1101. The filter plate 1102 is fixedly mounted on the top surface of the pull-out sealing plate 12. The filter plate 1102 is used to block the soil that falls into the wastewater discharge frame 11. When the soil is continuously deposited inside the wastewater discharge frame 11, the pull-out sealing plate 12 can be pulled outward to complete the soil cleaning operation. On the one hand, it is convenient for the discharged wastewater to be recycled, and at the same time, the soil can be collected and processed to avoid sedimentation during the discharge process, which causes cleaning difficulties. Specifically, the two groups of conveying shafts 6 are symmetrical to each other, and the ends of the same group of conveying shafts 6 are fixedly sleeved with mutually meshing transmission gears 601, and a servo motor is fixedly installed on the outer side of the body 1 to drive the corresponding conveying shaft 6 to operate. The servo motor is an existing device and is not shown in the figure; Specifically, the ends of two adjacent cleaning shafts 8 are fixedly sleeved with sprockets, and are rotatably connected to a transmission chain 801 through the sprockets to achieve transmission operations; Specifically, a protective cover 101 is fixedly installed on the outer side of the body 1; Furthermore, a negative pressure extraction rack 16 is fixed inside the body 1, and there are two negative pressure extraction racks 16, which are installed at the upper and lower sides of the photovoltaic panel body 4 respectively. A negative pressure device is installed on the outside of the body 1, and the negative pressure device is connected to the negative pressure extraction rack 16. When the cleaned photovoltaic panel body 4 is transported to the two negative pressure extraction racks 16, as the negative pressure device runs, negative pressure can be generated inside the two negative pressure extraction racks 16 to extract water droplets attached to the outer surface of the photovoltaic panel body 4. The negative pressure device is an existing negative pressure machine, not shown in the figure.

[0022] Embodiment 2: Based on Embodiment 1, the present invention discloses a novel photovoltaic panel cleaning method, which specifically comprises the following steps: S1, firstly, the photovoltaic panel body 4 is conveyed to the inside of the machine body 1 by the conveyor belt 2, and then, until the end of the photovoltaic panel body 4 moves between a set of conveying shafts 6, at this time, the photovoltaic panel body 4 can be clamped by the clamping conveying ring 7 installed outside the two conveying shafts 6, and the clamping conveying ring 7 is driven to run by the reverse rotation of the two conveying shafts 6; S2. When the end of the transported photovoltaic panel body 4 enters between the two cleaning shafts 8, as the cleaning shaft 8 runs, it can drive the multiple fixing rings 9 and the elastic cleaning brush 901 on the outside to run, so as to realize the brushing treatment of both sides of the photovoltaic panel body 4; S3. After being cleaned by the elastic cleaning brush 901, the photovoltaic panel body 4 can enter between the fixed disc racks 10. As the cleaning water passes through the fixed disc racks 10 and multiple high-pressure flushing heads 1001 and is sprayed toward the photovoltaic panel body 4, the flushing operation is performed until the photovoltaic panel body 4 contacts the running output belt 3 and is output, completing the cleaning process.
