[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0040] Reference Figures 1-6 The top of the bottom plate 11 is fixed with two telescopic rods 13 by bolts, and the telescopic ends of the two telescopic rods 13 are fixed with a collection box 10 by bolts. The top of the bottom plate 11 is provided with a power component 4 for carrying the collection box 10 to move up and down. One side of the collection box 10 is fixed with two guide rods 8 inclined by bolts. The outer sides of the two guide rods 8 are slidably connected with a slide 9. A cleaning roller 15 and a water absorption roller 3 are rotatably connected between the inner walls of the two sides of the slide 9, and the water absorption roller 3 is located obliquely above the cleaning roller 15. A spraying assembly 7 is provided between the inner walls of the two sides of the slide 9. A conveying assembly 2 connected to the collection box 10 and the spraying assembly 7 is provided on the outer side of the collection box 10. The side is provided with a driving assembly 1 for driving the slide 9 to move and the water-absorbing roller 3 and the cleaning roller 15 to rotate. The inclination angle of the guide rod 8 is the same as the inclination angle of the photovoltaic panel, and the water-absorbing material of the water-absorbing roller 3 is a sponge. First, the dust removal equipment is moved to the photovoltaic panel position so that the cleaning roller 15 contacts the water-absorbing roller 3 and the photovoltaic panel, and then the cleaning liquid is added to the collection box 10, and the conveying assembly 2 is started. The conveying assembly 2 drives the cleaning liquid to be sprayed from the spraying assembly 7 to the surface of the photovoltaic panel, and then the driving assembly 1 is started. The driving assembly 1 drives the water-absorbing roller 3 and the cleaning roller 15 to rotate, and at the same time drives the slide 9 to move downward. The slide 9 moves downward with the water-absorbing roller 3, the cleaning roller 15 and the spraying assembly 7, and the surface of the photovoltaic panel is scrubbed by the cleaning roller 15, thereby scrubbing off stubborn dirt adhering to the surface of the photovoltaic panel. At the same time, the water-absorbing roller 3 absorbs water stains on the surface of the photovoltaic panel, and the cleaning liquid sprayed on the surface of the photovoltaic panel will flow down along the slope of the photovoltaic panel and flow into the collection box 10, thereby greatly reducing the consumption of water resources.

[0041] In the present invention, the power assembly 4 includes a self-locking cylinder 401 fixed to the top of the base plate 11 by bolts, and the piston end of the self-locking cylinder 401 is fixed to the collection box 10. The collection box 10 is driven up and down by the self-locking cylinder 401, so that the dust removal equipment can clean photovoltaic panels at different heights, greatly improving the scope of use of the dust removal equipment.

[0042] In the present invention, the spray assembly 7 includes a water pipe 702 fixed between the inner walls on both sides of the slide 9 by bolts, the outer wall of the water pipe 702 and a plurality of nozzles 701 connected to the water pipe 702 are welded at the bottom, the outer wall of the water pipe 702 is fixed with a telescopic pipe 703 connected to the conveying assembly 2 by bolts, and the conveying assembly 2 includes a water pump 202 fixed to the outside of the collection box 10 by bolts, one end of the telescopic pipe 703 passes through the collection box 10 and is fixed to the water outlet of the water pump 202, and the water inlet position of the water pump 202 is fixed by bolts. There is a connecting pipe 201 connected to the bottom of the collection box 10. The circumferential inner wall of the connecting pipe 201 and one end of the collection box 10 are provided with a filter component 5 for filtering impurities. Start the water pump 202, and the water pump 202 extracts the cleaning liquid in the collection box 10 through the connecting pipe 201, and then discharges it from the water outlet into the telescopic tube 703. The conveying component 2 conveys the cleaning liquid into the telescopic tube 703, and then enters the water guide pipe 702 through the telescopic tube 703, and finally sprays it out from multiple nozzles 701, thereby washing away the floating dust on the surface of the photovoltaic panel.

[0043] In particular, in the present invention, the filter assembly 5 includes a filter box 501 inserted into the inner wall of the circumference of the connecting pipe 201 and located at one end of the collecting box 10, and a blocking assembly 6 is provided on the top of the filter box 501 to prevent impurities from flowing out. The blocking assembly 6 includes a baffle 605 fixed to the top of the filter box 501 by bolts, and a slide 604 is slidably connected to the inner wall of the circumference of the filter box 501. A through hole 603 with a smaller diameter than the baffle 605 is provided at the top of the slide 604 and at the bottom of the baffle 605. Two symmetrically arranged fixing plates 602 are welded to the inner wall of the filter box 501, and a spring 601 is provided between the fixing plate 602 and the slide 604, and the top of the spring 601 is fixed to the slide 604 The bottom end is fixed to the fixed plate 602, and the suction force of the connecting tube 201 on the cleaning liquid causes the cleaning liquid to push the slide plate 604 to move downward, and the cleaning liquid will enter the filter box 501 along the through hole 603 at the top of the slide plate 604. When not in use, the elastic force of the spring 601 pushes the slide plate 604 to move upward, so that the blocking frame 605 blocks the through hole 603, thereby preventing the impurities in the filter box 501 from returning to the collection box 10 again, and the impurities are always in the filter box 501, which greatly facilitates the cleaning of impurities. The cleaning liquid in the collection box 10 is filtered through the filter box 501, and some impurities are filtered out, which not only purifies the cleaning liquid, but also prevents impurities from clogging the nozzle 701.

[0044] In particular, in the present invention, the drive assembly 1 includes a slide rail 107 that is fixed to one side of the collection box 10 by bolts and is tilted. The top of the slide rail 107 is slidably connected to a movable frame 104, and the movable frame 104 is fixed to the slide 9. A connecting shaft 102 is rotatably connected between the top and the bottom inner wall of the movable frame 104 through a bearing. A worm gear 103 is connected to the circumferential outer side of the connecting shaft 102 through a key. A worm 105 that is meshed with the worm gear 103 and fixed to one end of the cleaning roller 15 is rotatably connected to the inner wall of one side of the cleaning roller 15 through a bearing. A servo motor that drives the worm 105 to rotate along the axis is fixed to the outer wall of one side of the movable frame 104 by bolts. A second gear 106 is connected to the outer side of the circumference of the connecting shaft 102 and at the bottom of the worm gear 103 through a key. A rack 108 that is tilted and meshed with the second gear 106 is fixed to one side of the collection box 10 by bolts. The outer side of the circumference of the cleaning roller 15 and at the end position is connected by a key. It is connected to a third gear 109, and the first gear 101 meshing with the third gear 109 is connected to the outer side of the circumference of the water-absorbing roller 3 and at the end through a key. The servo motor is started, and the output shaft of the servo motor drives the worm 105 to rotate. At the same time, the worm 105 drives the cleaning roller 15 to rotate, and the third gear 109 is meshed with the first gear 101, thereby driving the water-absorbing roller 3 to rotate. At the same time, the worm 105 drives the worm wheel 103 to rotate, and the worm wheel 103 drives the second gear 106 to rotate through the connecting shaft 102. Since the second gear 106 is meshed with the rack 108, the second gear 106 will roll on the rack 108, thereby driving the movable frame 104 to move downward, and the movable frame 104 drives the slide 9 to slide on the two guide rods 8. At the same time, the slide 9 moves downward with the water-absorbing roller 3, the cleaning roller 15 and the spray assembly 7, and through the cooperation of the worm wheel 103 and the worm 105, the second gear 106 is used to rotate slowly, and then the slide 9 is used to move slowly.

[0045] The working principle of this embodiment is as follows: when in use, first move the dust removal equipment to the photovoltaic panel position, so that the cleaning roller 15 contacts the water absorption roller 3 and the photovoltaic panel, then add the cleaning liquid into the collection box 10, and then start the water pump 202. The water pump 202 extracts the cleaning liquid in the collection box 10 through the connecting pipe 201, and then discharges it from the water outlet into the telescopic pipe 703, and then enters the water guide pipe 702 through the telescopic pipe 703, and finally sprays it from multiple nozzles 701 to the surface of the photovoltaic panel, and then start the servo motor. The output shaft of the servo motor drives the worm 105 to rotate, and at the same time the worm 105 drives the cleaning roller 15 to rotate, and the third gear 109 engages with the first gear 101, from The water-absorbing roller 3 is driven to rotate, and at the same time, the worm 105 drives the worm wheel 103 to rotate. The worm wheel 103 drives the second gear 106 to rotate through the connecting shaft 102. Since the second gear 106 is engaged with the rack 108, the second gear 106 will roll on the rack 108, thereby driving the movable frame 104 to move downward. The movable frame 104 drives the slide 9 to slide on the two guide rods 8. At the same time, the slide 9 moves downward with the water-absorbing roller 3, the cleaning roller 15 and the spray assembly 7. The surface of the photovoltaic panel is brushed by the cleaning roller 15. At the same time, the water-absorbing roller 3 absorbs the water stains on the surface of the photovoltaic panel. At the same time, the cleaning liquid sprayed on the surface of the photovoltaic panel will flow downward along the slope of the photovoltaic panel and flow into the collection box 10.
