Description

Technical Field

[0001] The invention belongs to the technical field of cleaning, and specifically relates to cleaning using tools, and in particular to a solar panel self-cleaning device and a cleaning process thereof. Background Art

[0002] Solar panels are devices that convert solar radiation into electrical energy; therefore, solar panels are often installed in open areas or high places without obstructions.

[0003] After the solar panel is used outdoors, its surface is easily blocked by dust or debris, which affects the reception of solar radiation. In the related art, a cleaning device is often slidably arranged on the solar panel, and the cleaning device moves along the upper surface of the solar panel to clean the surface dust and impurities.

[0004] However, due to the different regions of use and the different amounts of dust in the air in different seasons, especially in autumn and winter, when the dust is heavier, the thickness of dust accumulated on the surface of the solar panel will be higher. In this state, the contact area between the brush of the traditional cleaning device and the upper surface of the solar panel is reduced, resulting in a poor cleaning effect.

[0005] Therefore, how to solve the problem that the cleaning effect of the cleaning device becomes worse when the dust thickness on the surface of the solar panel increases is a technical problem that needs to be solved urgently in this field.

[0006] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0026] The outer wall of the regulating column is provided with a plurality of guide grooves along the axial direction, and one guide groove corresponds to one guide hole.

[0027] In an optional embodiment, a plurality of through holes are opened in the axial direction on the inner wall of the collecting tank, the through holes penetrate the adjusting column, and the aperture of the through holes is smaller than the aperture of the guide hole.

[0028] In an optional embodiment, the guide groove faces the side wall of the basic frame, wherein, after the mixture during the cleaning process flows into the guide groove, the solid-liquid mixture is suitable for increasing the friction between the adjusting column and the basic frame, so that the adjusting column rotates circumferentially relative to the basic frame.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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.

[0053] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limited. As used herein, the singular articles "one", "an" and "the" may also be intended to include plural forms, unless it is clearly indicated above that this is not the case.

[0055] After research, it was found that the disadvantage of the prior art is that after the solar panel is used outdoors, its surface is easily blocked by dust or debris, which affects the reception of solar radiation. In the related art, a cleaning device is often slidably set on the solar panel, and the cleaning device moves along the upper surface of the solar panel to clean the surface dust and impurities.

[0056] However, due to the different regions of use and the different amounts of dust in the air in different seasons, especially in autumn and winter, when the dust is heavier, the thickness of dust accumulated on the surface of the solar panel will be higher. In this state, the contact area between the brush of the traditional cleaning device and the upper surface of the solar panel is reduced, resulting in a poor cleaning effect.

[0057] Therefore, how to solve the problem that the cleaning effect of the cleaning device becomes worse when the dust thickness on the surface of the solar panel increases is a technical problem that needs to be solved urgently in this field.

[0058] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0059] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0060] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0061] like Figures 1 to 5As shown, some embodiments provide a solar panel self-cleaning device 3, including: a solar panel 1, which is arranged in a base frame 2; the upper surface of the solar panel 1 protrudes from the base frame 2, and the base frame 2 is suitable for supporting and limiting the position of the solar panel 1. A cleaning device 3, which is slidably arranged on the upper surface of the solar panel 1; when the cleaning device 3 slides along the upper surface of the solar panel 1, the brush 32 rotates to clean the impurities on the upper surface of the solar panel 1. An adjusting device 4, which is rotatably arranged at the bottom of the cleaning device 3 and abuts against the bottom wall of the base frame 2; when the cleaning device 3 moves, the adjusting device 4 synchronously slides on the bottom wall of the base frame 2 to limit the position of the cleaning device 3. Among them, when the cleaning device 3 moves along the upper surface of the solar panel 1, the adjusting device 4 slides along the bottom wall of the solar panel 1 to limit the distance between the cleaning device 3 and the upper surface of the solar panel 1; after the mixture in the cleaning process flows into the adjusting device 4, the adjusting device 4 is suitable for circumferential rotation relative to the solar panel 1. The setting of the adjustment device 4 improves the stability of the cleaning device 3 when it moves on the solar panel 1. When the driving wheel 33 drives the support frame 31 to move along the surface of the solar panel 1, at least two limiting balls 43 abut against the bottom wall of the base frame 2, so that the distance between the brush 32 and the solar panel 1 is kept within the normal working range, avoiding the situation where the brush 32 cannot contact the upper surface of the solar panel 1 due to excessive impurities on the surface of the solar panel 1, thereby improving the cleaning effect. The circumferential rotation of the adjustment column 44 relative to the base frame 2 can also prevent two limiting balls 43 from always rubbing against the bottom wall of the base frame 2, thereby improving the service life of the limiting balls 43.

[0062] Reference Figure 2 The cleaning device 3 comprises: a support frame 31, which is parallel to the solar panel 1 and is slidably arranged above the solar panel 1; a driving member is arranged on the side wall of the support frame 31, and the brush 32 and the driving wheel 33 are both connected to the driving member in a transmission manner, and the driving member is suitable for driving the brush 32 and the driving wheel 33 to rotate circumferentially. The brush 32 is rotatably arranged on the side wall of the support frame 31 and is suitable for cleaning impurities on the upper surface of the solar panel 1; the driving wheel 33 has an outer wall that abuts against the upper surface of the solar panel 1 and is rotatably arranged on the side wall of the support frame 31; wherein the driving wheel 33 rotates circumferentially and is suitable for driving the support frame 31 to move along the upper surface of the solar panel 1.

[0063] Furthermore, the cleaning device 3 further comprises a water pipe 34, the water pipe 34 and the brush 32 are parallel to each other, and a plurality of spray holes are formed on the outer wall of the water pipe 34, and the spray holes face the solar panel 1. A liquid inlet pipe connected to the water pipe 34 is disposed on the side wall of the support frame 31, and the liquid inlet pipe is suitable for conveying cleaning liquid into the water pipe 34. After the cleaning liquid in the water pipe 34 is sprayed onto the upper surface of the solar panel 1 through the spray holes, the brush 32 rotates circumferentially to clean impurities on the upper surface of the solar panel 1, further improving the cleaning effect on the upper surface of the solar panel 1.

[0064] In order to improve the stability of the support frame 31, there are at least two driving wheels 33, and the two driving wheels 33 are symmetrically arranged on both sides of the brush 32. The two driving wheels 33 are arranged on both sides of the brush 32, and when the driving wheels 33 drive the support frame 31 to move, the stability of the brush 32 can be ensured when it is working.

[0065] Reference Figure 4 The adjusting device 4 comprises: a positioning column 41, which is arranged on the bottom wall of the support frame 31 and is parallel to the base frame 2; a positioning turntable 42, which is sleeved on the outer wall of the positioning column 41 and arranged below the base frame 2; the positioning turntable 42 is suitable for circumferential rotation relative to the positioning column 41, and when the adjusting column 44 is not subjected to a greater friction force, the adjusting column 44 will not rotate relative to the positioning column 41, and at this time, the positioning turntable 42 remains stationary relative to the positioning column 41. A plurality of limiting balls 43 are arranged circumferentially around the upper surface of the positioning turntable 42 and are suitable for abutting against the bottom wall of the base frame 2; wherein, when the support frame 31 moves along the upper surface of the solar panel 1, at least two limiting balls 43 abut against the bottom wall of the base frame 2. The arrangement of the limiting balls 43 and the positioning turntable 42 means that when the support frame 31 moves along the upper surface of the solar panel 1, the limiting balls 43 abut against the base frame 2 from the lower end thereof, thereby preventing the base frame 2 from moving away from the solar panel 1. Therefore, even if the impurities accumulated on the upper surface of the solar panel 1 are thick, the impurities on the upper surface of the solar panel 1 cannot push the brush 32 to move away from the solar panel 1. The setting of the limiting ball 43 ensures the distance between the brush 32 and the upper surface of the solar panel 1, so that the brush 32 can always contact with the upper surface of the solar panel 1, so as to play the effect of cleaning the upper surface of the solar panel 1 when the brush 32 rotates.

[0066] Reference Figure 5, an adjusting column 44 is provided at the upper end of the positioning turntable 42, which is sleeved on the outer wall of the positioning column 41 and abuts against the outer wall of the base frame 2; the adjusting column 44 is suitable for limiting the support frame 31 to prevent the support frame 31 from shaking left and right relative to the solar panel 1. When the support frame 31 moves along the upper surface of the solar panel 1, the adjusting column 44 will not rotate relative to the positioning column 41 at this time. When the friction between the outer wall of the adjusting column 44 and the side wall of the base frame 2 increases, as the support frame 31 moves horizontally, the adjusting column 44 is suitable for rotating relative to the positioning column 41, and the rotation of the adjusting column 44 is suitable for driving the positioning turntable 42 to rotate circumferentially, so that the limiting balls 43 at other adjacent positions move to the bottom wall of the base frame 2.

[0067] Reference Figure 5 The upper end of the adjusting column 44 is provided with a collecting groove, and the inner wall of the collecting groove is provided with a plurality of guide holes 45; the outer wall of the adjusting column 44 is provided with a plurality of guide grooves 46 along the axial direction, and one guide groove 46 corresponds to one guide hole 45. The inner wall of the collecting groove is provided with a plurality of through holes 47 along the axial direction, and the through holes 47 penetrate the adjusting column 44, and the aperture of the through holes 47 is smaller than the aperture of the guide holes 45. When the cleaning liquid sprayed outward by the water pipe 34 flows to both sides along the solar panel 1, part of the solid-liquid mixture flows into the collecting groove along the surface of the solar panel 1. When the volume of the inflowing mixture exceeds the through hole 47, part of the solid-liquid mixture flows to the guide groove 46 through the guide hole 45; because the side wall of the adjusting column 44 abuts against the side wall of the basic frame 2, part of the solid impurities in the guide groove 46 will adhere between the outside of the basic frame 2 and the outer wall of the adjusting column 44. At this time, when the support frame 31 moves horizontally, the friction between the adjusting column 44 and the basic frame 2 increases, so the adjusting column 44 will rotate circumferentially relative to the positioning column 41. The rotation of the adjusting column 44 drives the positioning turntable 42 to rotate synchronously, so that the limiting ball 43 located at the bottom of the basic frame 2 is replaced by other adjacent limiting balls 43, avoiding a certain limiting ball 43 from being worn on the bottom wall of the basic frame 2 for a long time.

[0068] Furthermore, the guide groove 46 faces the side wall of the basic frame 2, wherein, after the mixture in the cleaning process flows into the guide groove 46, the solid-liquid mixture is suitable for increasing the friction between the adjustment column 44 and the basic frame 2, so that the adjustment column 44 rotates circumferentially relative to the basic frame 2.

[0069] Some embodiments provide a solar panel self-cleaning device, comprising: a cleaning device 3, comprising: a pair of driving wheels, the two driving wheels are respectively located at the edges of the upper surface of the base frame 2, and a brush is arranged between the two driving wheels;

[0070] The adjusting device 4 comprises: a pair of positioning turntables 42, which are respectively arranged at the edges of the lower surface of the base frame 2, and a plurality of limiting balls are evenly arranged on the upper surface of the positioning turntable 42 in the circumferential direction;

[0071] When the driving wheel rolls on the upper surface of the base frame 2, it drives the positioning turntable 42 to rotate to drive at least two limiting balls to alternately abut against the lower surface of the base frame 2, so that the cleaning device is stable, that is, the distance between the brush and the upper surface of the base frame 2 is limited.

[0072] Some embodiments provide a cleaning process, the cleaning process comprising:

[0073] When the cleaning device 3 moves along the upper surface of the solar panel 1, the adjusting device 4 slides along the bottom wall of the solar panel 1 to limit the distance between the cleaning device 3 and the upper surface of the solar panel 1, so that the circumferential rotation of the brush 32 can clean impurities on the surface of the solar panel 1;

[0074] The brush 32 of the cleaning device 3 rotates circumferentially to clean the impurities on the surface of the solar panel 1, and the water pipe 34 sprays water outward to further clean the impurities on the surface of the solar panel 1;

[0075] After the mixture in the cleaning process flows into the regulating device 4, the regulating column 44 of the regulating device 4 rotates circumferentially to move the limiting balls 43 at other positions to the bottom wall of the basic frame 2, thereby avoiding long-term friction damage to the limiting balls 43.
