DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1

[0024] See also Figures 1 to 3 The present embodiment provides a photovoltaic cleaning component, including a frame 1, a bracket 4 fixed to the top of the frame 1, a driving component 6 is arranged on the bracket 4, a positioning plate 5 is fixedly connected to the lower end of the driving component 6, a cleaning strip 2 is arranged under the frame 1, the cleaning strip 2 is detachably mounted on the bottom of the positioning plate 5, a cleaning cloth 3 is fixedly connected to the bottom of the cleaning strip 2, and the vertical position of the cleaning strip 2 is adjusted by the driving component 6, thereby adjusting the degree of compression between the cleaning cloth 3 and the photovoltaic panel.

[0025] The driving assembly 6 includes a screw 61 rotatably inserted on the bracket 4, the screw 61 is vertically distributed, the lower end of the screw 61 is threadedly sleeved with an internal threaded sleeve 62, the lower end of the internal threaded sleeve 62 is fixedly connected to the positioning plate 5, a guide sleeve 63 is fixedly connected to the top of the bracket 4, a guide rod 64 is movably inserted inside the guide sleeve 63, the lower end of the guide rod 64 is fixedly connected to the positioning plate 5, and the upper end of the screw 61 is fixedly connected to a handwheel 65.

[0026] Turning the hand wheel 65 drives the screw 61 to rotate, and the screw 61 drives the internal threaded sleeve 62 to move vertically, thereby adjusting the distance between the positioning plate 5 and the surface of the photovoltaic panel, so that the degree of compression between the cleaning cloth 3 and the photovoltaic panel can be adjusted, thereby avoiding excessive pressure from causing greater wear between the cleaning cloth 3 and the photovoltaic panel, and preventing damage to the photovoltaic panel. Under normal circumstances, a more appropriate pressure is used to clean the photovoltaic panel; the pressure can be judged by the degree of deformation of the cleaning cloth 3; when the stains on the surface of the photovoltaic panel are difficult to scrape off, the pressure can be increased to scrape off the stains.

[0027] A plurality of latches 7 are fixedly connected to the top of the cleaning strip 2, and a stud 8 is fixedly connected to the upper end of the latch 7. A positioning hole 501 is opened on the positioning plate 5, and the upper end of the latch 7 is arranged through the positioning hole 501. An internal threaded tube 9 is threadedly sleeved on the stud 8, and the lower end of the internal threaded tube 9 is in contact with the positioning plate 5.

[0028] When replacing the cleaning strip 2, turn the hand wheel 65 to drive the screw 61 to rotate, so that the internal threaded sleeve 62 moves upward, and the positioning plate 5 moves upward with the internal threaded sleeve 62, thereby moving the cleaning strip 2 upward. At this time, there is a gap between the cleaning strip 2 and the photovoltaic panel. Then loosen the internal threaded tube 9, remove the pin 7 and the stud 8 from the inside of the positioning hole 501, and disassemble the cleaning strip 2.

[0029] Specifically, the positioning hole 501 is a round hole, the latch pin 7 is a cylindrical pin, and there is a transition fit between the latch pin 7 and the positioning hole 501 .

[0030] It should be further explained that the cleaning cloth 3 is a kind of microfiber cloth or sponge. The microfiber cloth has a fine fiber structure, which can effectively absorb moisture and cleaning liquid without leaving fiber residue or scratches on the surface of the photovoltaic panel. The sponge is soft and easy to wipe, which can effectively remove dirt on the surface of the photovoltaic panel without causing scratches.

[0031] In addition, the cleaning cloth 3 is fixed to the bottom of the cleaning strip 2 by gluing, ensuring that the cleaning cloth 3 is firmly fixed to the cleaning strip 2, thereby effectively cleaning the surface of the photovoltaic panel.
