[0029] 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.

[0030] Household solar panels are generally small in size and are installed on roofs or windowsills, which are not convenient for manual cleaning. However, fully automated solar panel cleaning robots are usually expensive and not suitable for home use. The present invention patent designs a low-cost solar panel dust cleaning device suitable for home use.

[0031] If it does not rain for a long time, the solar panels will accumulate dust that is difficult to clean, and even clump. The dust coverage is the biggest problem affecting the photovoltaic conversion efficiency of the solar panels. It is often difficult to clean them thoroughly with a simple brush. The patent of the present invention uses low-cost tape for cleaning. If the tape is not too dirty after one use, it can be rolled back and used again.

[0032] For specific embodiment 1, please refer to Figure 1-8The present invention is a dust cleaning device for solar panels, comprising two symmetrically arranged mounting plates 1; the mounting plates 1 can be fixedly mounted on a mounting frame of a solar panel, and the solar panel 2 is located between the two mounting plates 1; a first winding roller 3 is rotatably arranged between the two mounting plates 1; a tape 4 is wound around the side surface of the first winding roller 3; an annular groove is provided on the side surface of one mounting plate 1; the annular groove comprises an upper straight track 5, a lower straight track 6, and two first arc tracks 7 and a second arc track 9 connecting the two ends of the upper straight track 5 and the lower straight track 6; a second winding roller 10 is slidably arranged on the inner wall of the annular groove; one end of the tape 4 is wound and fixed on the side surface of the first winding roller 3, and the other end thereof is wound and fixed on the side surface of the second winding roller 10; a plurality of grooves 11 are evenly distributed in a circular array on one end of the second winding roller 10; a plurality of protrusions 12 matching the inner wall of the groove 11 are evenly distributed on the inner wall of the upper straight track 5 in a linear array.

[0033] Specifically, a slide groove 13 is provided on the side of the other mounting plate 1; the slide groove 13 is parallel to the solar panel 2; a reciprocating screw 14 is rotatably provided on the inner wall of the slide groove 13; a slider 15 is slidably provided on the inner wall of the slide groove 13; a slide hole 16 is penetrated on the side of the slider 15; a sliding block that slides with the thread groove of the reciprocating screw 14 is provided on the inner wall of the slide hole 16.

[0034] Furthermore, a limit plate 20 is fixed to the inner bottom surface of the guide groove 19; a plurality of limit grooves 21 that are evenly distributed in a circular array and plugged into and cooperate with the limit plate 20 are provided at the other end of the second winding roller 10; a servo motor 22 is fixed to the side of a mounting plate 1; and the output end of the servo motor 22 is fixedly connected to the first winding roller 3.

[0035] Furthermore, a mounting groove 23 is opened on the side of a mounting plate 1; two adjacent inner walls of the mounting groove 23 are rotatably provided with mutually meshing bevel gears 24; one bevel gear 24 is fixedly connected to one end of the first winding roller 3; and the other bevel gear 24 is fixedly connected to one end of the reciprocating screw rod 14.

[0036] The operation process of this embodiment is as follows: in the initial state, the second winding roller 10 is located at the connection between the first arc track 7 and the lower straight track 6, and then the side of the tape 4 on the first winding roller 3 with glue is located on the inner side, and the side of the tape 4 on the second winding roller 10 with glue is located on the outer side.

[0037] Start the servo motor 22 to drive the first winding roller 3 to rotate, and then drive the corresponding bevel gear 24 to rotate, and then drive the other bevel gear 24 to rotate, and then drive the reciprocating screw 14 to rotate, and then drive the sliding block in the sliding hole 16 to slide along the threaded groove of the reciprocating screw 14, and then drive the slider 15 to slide along the inner wall of the slide groove 13, and then drive the second winding roller 10 to slide along the inner wall of the lower straight track 6, and pull the tape 4 along the surface of the solar panel 2 until it covers the surface of the solar panel 2, and the dust on the surface of the solar panel 2 is adhered to the tape 4. At this time, a limit groove 21 on the second winding roller 10 is plugged into and matched with the limit plate 20 in the guide groove 19, and the second winding roller 10 cannot rotate.

[0038] Then the reciprocating screw rod 14 drives the slider 15 to slide back, and at this time the second winding roller 10 slides from the lower straight track 6 into the second arc track 9 and finally slides into the upper straight track 5. At this time, the limiting groove 21 on the second winding roller 10 is disengaged from the limiting plate 20 in the guide groove 19, so that the second winding roller 10 can rotate, and then the reciprocating screw rod 14 drives the slider 15 to slide back, and drives the second winding roller 10 to move on the upper straight track 5. When the groove 11 on the second winding roller 10 contacts the protrusion 12 on the upper straight track 5, it drives the second winding roller 10 to rotate and move along the inner wall of the upper straight track 5, and then drives the second winding roller 10 to roll up the dusty tape 4 until it returns to the original position. At this time, the dust cleaning of the tape 4 is completed.

[0039] In this embodiment, by driving the second winding roller 10 to move inside the annular groove, when the second winding roller 10 moves on the inner wall of the lower straight track 6, the second winding roller 10 does not rotate, and pulls the tape 4 to cover the entire surface of the solar panel 2 to pick up dust. When the second winding roller 10 moves on the inner wall of the upper straight track 5, the second winding roller 10 rotates and moves back to reel in the dusty tape 4, thereby realizing automatic dust cleaning with low cost.

[0040] For specific embodiment 2, please refer to Figure 1-8 On the basis of the specific embodiment 1, an adjustment groove 17 is opened through the inner wall of the slide groove 13; an adjustment plate 18 is fixed to the side of the slider 15; the adjustment plate 18 is slidably arranged on the inner wall of the adjustment groove 17; a guide groove 19 is opened on the side of the adjustment plate 18; and the side surface of the second winding roller 10 is adapted to the inner wall of the guide groove 19.

[0041] Specifically, an L-shaped mounting block 25 is fixed on the side of the adjustment plate 18 ; a pressing roller 26 is rotatably provided on the side of the L-shaped mounting block 25 ; and the side surface of the pressing roller 26 is adapted to the surface of the solar panel 2 .

[0042] Furthermore, the pressing roller 26 is located above the adhesive tape 4; one end of the adhesive tape 4 is wound and fixed on the side of the first winding roller 3, and the other end thereof passes under the pressing roller 26 and is wound and fixed on the side of the second winding roller 10.

[0043] Furthermore, two fixing blocks 27 are fixed to the side of a mounting plate 1; one fixing block 27 is close to the top of the first arc track 7; the other fixing block 27 is close to the bottom of the second arc track 9; a spring 28 is fixed on the fixing block 27; a push block 8 slidably set on the side of the mounting plate 1 is fixed to one end of the spring 28; one side of the push block 8 is chamfered.

[0044] The operation process of this embodiment is as follows: when the reciprocating screw rod 14 rotates, it drives the slider 15 to slide along the inner wall of the slide groove 13, and at the same time drives the adjusting plate 18 to slide along the inner wall of the adjusting groove 17, thereby driving the second winding roller 10 to pull the tape 4 and spread the tape 4 on the surface of the solar panel 2. At the same time, the adjusting plate 18 drives the L-shaped mounting block 25 to move, thereby driving the pressing roller 26 to press on the surface of the solar panel 2 to improve the efficiency of dust adhesion. When the second winding roller 10 moves to the connection between the lower straight track 6 and the second circular arc track 9, it first pushes the corresponding push block 8 to slide downward and compresses the spring 28. When the second winding roller 10 completely slides into the second circular arc track 9, the spring 28 pushes the push block 8 to slide upward, so that the second winding roller 10 slides from the lower half of the second circular arc track 9 to the upper half, preventing the second winding roller 10 from returning to the lower straight track 6 when winding the tape 4.

[0045] Then the reciprocating screw rod 14 drives the slider 15 to slide back along the slide groove 13, and at the same time drives the adjustment plate 18 to slide along the inner wall of the adjustment groove 17, thereby driving the second winding roller 10 to move the winding tape 4 inside the upper straight track 5. When the second winding roller 10 moves to the connection between the upper straight track 5 and the first circular arc track 7, it first pushes the corresponding push block 8 to slide upward and compresses the spring 28. When the second winding roller 10 completely slides into the first circular arc track 7, the spring 28 pushes the push block 8 to slide downward, so that the second winding roller 10 slides from the upper half of the first circular arc track 7 to the lower half, preventing the second winding roller 10 from returning to the upper straight track 5 when pulling the tape 4.

[0046] In this embodiment, the push block 8 is set to complete the switching of the second winding roller 10 between the upper straight track 5 and the lower straight track 6. First, the second winding roller 10 contacts the push block 8, and then the push block 8 is slowly pushed to move the extrusion spring 28. After the second winding roller 10 completely enters the first circular arc track 7 or the second circular arc track 9, the spring 28 pushes the push block 8 to slide, and then pushes the second winding roller 10 to slide, completing the switching of the second winding roller 10 between the upper straight track 5 and the lower straight track 6, thereby realizing the restriction and release of the rotation of the second winding roller 10.
