Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation panels, and in particular to a photovoltaic power generation panel surface self-cleaning device. Background Art

[0002] Photovoltaic panels, also known as solar panels or photovoltaic panels, are devices that use the photoelectric effect to convert sunlight directly into electrical energy;

[0003] Photovoltaic panels are used outdoors. After long-term use, more impurities will adhere to the surface. In order not to affect the light energy conversion efficiency of photovoltaic panels, it is necessary to clean the impurities on the surface of photovoltaic panels. The existing cleaning methods are mostly manual or mechanical equipment to directly rinse with water or to wipe the dust after rinsing with a brush or mop after passing through the surface of the panel.

[0004] The above cleaning method can remove dust attached to the surface of the power generation panel, but in practice, the impurities on the surface of the power generation panel are not all directly attached dust, but there are many points or small pieces of dirt condensed in the local distribution, such as bird droppings and dirt condensed after liquid carries dust. The difference between these two types of dirt and dust impurities is that the attached dust can be directly cleaned off by local flushing and wiping, while the dirt cannot be cleaned off due to its strong adhesion. The existing cleaning method is to clean a large area on the surface of the power generation panel, just like when a towel is wiped on the glass surface, there will be small spots of dirt that cannot be cleaned off. This will result in the dirt still existing after multiple cleanings, and it is impossible to efficiently clean each point where the dirt is distributed on the surface of the power generation panel.

[0040] The cleaning group includes a round rod 3 and a clearance groove 9, the two ends of the round rod 3 are rotatably connected between the two slide plates 2, a plurality of sets 4 are fixedly connected to the two round rods 3, and the plurality of sets 4 are arranged at equal intervals along the outside of the round rod 3, and the inside of the sets 4 are slidably connected with contact members 5, and a first spring 6 is fixedly connected between the contact members 5 and the sets 4, and a cleaning cloth 7 is arranged on the contact members 5, and a driving rod 8 is located directly below the round rod 3, and the clearance groove 9 is opened on the side wall of the set 4 located at the outermost side, and the end of the driving rod 8 is located inside the clearance groove 9;

[0042] The driving group includes a reciprocating screw 10 and a vertical slot 13. The reciprocating screw 10 is driven by an external driving device. The reciprocating screw 10 is rotatably connected to the mounting plate 1. The reciprocating screw 10 is threadedly connected to the slide plate 2. A first motor 11 is fixedly connected to the slide plate 2. The output shaft of the first motor 11 is fixedly connected to an L-shaped rod 12.

[0043] like Figure 1 , 2 , 3, 8 Figure 10-13 As shown:

[0044] The two mounting plates 1 are fixedly connected to the outer frame of the power generation panel, or connected by bolts. When in use, the surface of the power generation panel is first rinsed with water, or it can be kept rinsed while the cleaning group is performing cleaning work. The reciprocating screw 10 is driven to rotate by an external driving motor. When the reciprocating screw 10 rotates, the first motor 11 is also started at the same time. The reciprocating screw 10 will drive the slide plate 2 to move in the left and right directions along the side wall of the mounting plate 1. At this time, the contact member 5 will move along the surface of the power generation panel. During the movement of the slide plate 2, the first motor 11 will drive the L-shaped rod 12 to rotate inside the vertical groove 13, thereby pushing the driving rod 8 to slide back and forth along the slide plate 2. The two round rods 3 are both rotatably connected to the slide plate 2, and the end of the driving rod 8 is located inside the give way groove 9, so when the driving rod 8 moves back and forth, it will drive the pushing kit 4 and the contact member 5 swing back and forth around the rotation axis of the round rod 3, and the swinging trajectory is an arc (after swinging left and right to the maximum extent, the contact member 5 will be out of contact with the surface of the power generation board for a short distance), and the bottom end of the contact member 5 is on the surface of the power generation board, so when the contact member 5 swings left and right, it will continuously contact and rub with the surface of the power generation board, thereby cleaning the dirt with strong adhesion on the surface of the power generation board. After contact, the surface of the power generation board will give a resistance effect to the contact member 5 and the cleaning cloth 7. At this time, the contact member 5 will slide along the kit 4 and compress the first spring 6, then the contact member 5 will react to give a downward pressure to the surface of the power generation board, so that when cleaning the surface of the power generation board, the cleaning effect can be stronger under the action of the downward pressure, thereby ensuring that the dirt can be cleaned;

[0045] Moreover, the sets 4 on each round rod 3 are arranged at intervals, and the sets 4 on the two round rods 3 are also arranged at intervals, so when the round rod 3 swings to allow the contact piece 5 and the cleaning cloth 7 to clean the dirt, the cleaning is carried out in a distribution manner of points or blocks, rather than a large-scale wiping in the traditional cleaning method, and during cleaning, the swing of the arc trajectory can press down on multiple points on the surface of the power generation panel to ensure that the dirt on the surface of the power generation panel in the form of points or blocks can be cleaned, so that the cleaning cloth 7 can ensure that the dirt is cleaned during friction, and when the slide plate 2 moves, the sets 4 and the contact pieces 5 on the round rods 3 on the left and right sides can cover the entire surface area of ​​the power generation panel, thereby ensuring that the surface of the power generation panel can be cleaned, and the cleaning work can be stopped after the slide plate 2 moves to the other side of the power generation panel.

[0046] A cleaning group is provided above the round rod 3;

[0047] The cleaning group includes a fixed rod 14 and a movable rod 15, and the fixed rod 14 and the movable rod 15 are arranged in a staggered manner. The two ends of the fixed rod 14 are respectively fixedly connected to the top ends of the two slide plates 2, and the top angle and the bottom angle of the side walls opposite to the fixed rod 14 and the movable rod 15 are provided with inclined surfaces. The fixed rod 14 and the movable rod 15 are provided with accommodating grooves 16 with the same number as the cleaning cloth 7. The cleaning cloth 7 is a circular ring. The cleaning cloth 7 passes through the accommodating grooves 16 in the fixed rod 14 and the movable rod 15 above it respectively, and the cleaning cloth 7 is located below the contact member 5. The movable rod 15 is slidably connected with a first rack rod 17 near the front and rear ends, and the first rack rod 17 is L-shaped. A second spring 18 is fixedly connected between the first rack rod 17 and the inner wall of the movable rod 15. The two first rack rods 17 are respectively slidably connected with the two slide plates 2 in the vertical direction, and a third spring 19 is fixedly connected between the first rack rod 17 and the slide plate 2. The first rack rod 17 is meshed with an incomplete gear 20.

[0048] A conveying group is arranged below the movable rod 15 , and the conveying group drives the cleaning cloth 7 to rotate and change position and supports and drives the incomplete gear 20 .

[0049] The conveying group includes two second rack rods 21, two gears 22 and two second friction wheels 27, the two second rack rods 21 are respectively fixedly connected to the top of the two mounting plates 1, the two gears 22 are respectively meshed with the two second rack rods 21 and the two gears 22 are rotatably connected to the slide plate 2, the rotating shafts of the gears 22 are fixedly connected with the lifting wheels 23, the lifting wheels 23 are all partially cut circles, and the lifting wheels 23 are provided with push rods 24 above. After the arc surface of the lifting wheel 23 contacts the push rod 24, the push rod 24 can be lifted up, and the push rod 24 is slidably connected to the slide plate 2 on one side thereof in the vertical direction, the push rod 24 is fixedly connected with the second motor 25, the output shaft of the second motor 25 is fixedly connected with the first friction wheel 26, the second friction wheel 27 is fixedly connected with the two incomplete gears 20, the rotating shafts of the two second friction wheels 27 are respectively rotatably connected to the inner walls of the two slide plates 2, and the first friction wheel 26 can contact the second friction wheel 27 after rising to the highest point and drive the second friction wheel 27 to rotate;

[0050] The conveying group also includes a transposition group, an adaptation group and a clamping group.

[0051] The clamping group includes two support rods 28 and two push plates 29, which are respectively distributed at the two ends of the fixed rod 14 and the two movable rods 15. The two push plates 29 are both slidably connected to the slide plate 2 on one side thereof in the horizontal direction. The top ends of the two support rods 28 are rotatably connected to the two push plates 29. The two support rods 28 are rotatably connected to the top ends of the two top rods 24 respectively. Wedge blocks 30 are provided on the inner sides of the two push plates 29. The wedge blocks 30 are slidably connected to the movable rod 15. A fourth spring 31 is fixedly connected between the wedge blocks 30 and the inner wall of the movable rod 15. The two wedge blocks 30 are both located inside the movable rod 15. A clamping rod 32 is commonly provided on one side of the two wedge blocks 30 close to the accommodating groove 16. The clamping rod 32 is used to squeeze the cleaning cloth 7.

[0052] The transposition group includes two cross bars 33, both ends of the two cross bars 33 are rotatably connected with T-shaped bars 34, the rotation axes of the cross bars 33 are sleeved with torsion springs 41, the two T-shaped bars 34 are respectively slidably connected with the two top bars 24, and the two T-shaped bars 34 and the top bars 24 are fixedly connected with a fifth spring 35, and the two cross bars 33 are fixedly connected with a plurality of thorn pieces 36, and the plurality of thorn pieces 36 on the two cross bars 33 are respectively located on the front and rear sides of the cleaning cloth 7.

[0053] The adaptation group includes a first resistance rod 37 corresponding to the kit 4 one by one, a third resistance rod 40 distributed on the front and rear sides of each contact piece 5 and fixedly connected to the kit 4, and a second resistance rod 39. The first resistance rods 37 are respectively fixedly connected to the side of the kit 4 away from the cross bar 33. The first resistance rods 37 are slidably connected to the side wall of the kit 4. A sixth spring 38 is fixedly connected between the first resistance rod 37 and the side wall of the kit 4. The second resistance rod 39 is located below the cross bar 33 and its two ends are respectively fixedly connected to the two top rods 24.

[0054] As shown in the figure:

[0055] Because the cleaning cloth 7 cleans the dirt in the range of points or blocks by friction and downward pressure, the dirt may adhere to the cleaning cloth 7 after being cleaned by the cleaning cloth 7 through friction, and the adhesion is strong and will not fall off easily. If it cannot be cleaned, it will accumulate on the cleaning cloth 7 to form lumps and affect the subsequent cleaning effect;

[0056] Therefore, when the slide plate 2 slides along the mounting plate 1, the gear 22 will always keep meshing with the second rack rod 21 and move along with the slide plate 2. When the gear 22 rotates, it will drive the lifting wheel 23 to rotate. When the circular surface of the lifting wheel 23 does not contact the bottom end of the push rod 24, the push rod 24 is at the lowest point. When the circular surface of the lifting wheel 23 contacts the push rod 24, the push rod 24 will be lifted up. At this time, the push rod 24 will slide and rise along the slide plate 2.

[0057] When the top rod 24 rises;

[0058] The rising of the top rod 24 will drive the T-bar 34 to rise, and the T-bar 34 will drive the second resisting rod 39 and the cross bar 33 to rise. When the cross bar 33 rises, it will drive several ratchet pieces 36 to rise a short distance along the cleaning cloth 7 in a straight line. The rising of the top rod 24 will also push the push plate 29 through the support rod 28 to slide along the slide plate 2 in the horizontal direction toward the movable rod 15, and the push plate 29 will push the wedge block 30 to slide along the movable rod 15 and compress the fourth spring 31, so that the wedge block 30 will push the clamping rod 32 through its inclined surface to clamp several cleaning cloths 7 in the accommodating groove 16. After the push plate 29 pushes the wedge block 30 to the extreme position, the first friction wheel 26 will rise to the position of contacting with the second friction wheel 27, and the second motor 25 is started at the same time as the first motor 11, so when the first friction wheel 26 contacts the second friction wheel 27, the first friction wheel 26 will drive the second friction wheel 27 to rotate, and when the second friction wheel 27 rotates, it will drive the incomplete gear 20 to rotate, so the incomplete gear The wheel 20 will drive the first rack rod 17 to slide up and down along the slide plate 2 and compress the third spring 19. After the tooth portion of the incomplete gear 20 is disengaged from the first rack rod 17, the first rack rod 17 will be reset under the reset of the third spring 19, so the first rack rod 17 is in a continuous rising and falling process, then the first rack rod 17 will drive the movable rod 15 in a continuous lifting process, and the side walls of the movable rod 15 and the fixed rod 14 are both chamfered, so when the movable rod 15 rises, the movable rod 15 will maintain the fit with the side walls of the fixed rod 14 to rise and fall, and in this process, the movable rod 15 will also slide along the first rack rod 17 and make the second spring 18 repeatedly stretched and reset, and the clamping rod 32 clamps the cleaning cloth 7 inside the accommodating groove 16 of the movable rod 15, so when the movable rod 15 is lifted and lowered along the fixed rod 14, the cleaning cloth 7 between the movable rod 15 and the fixed rod 14 will be repeatedly rubbed (such as Fig.12 As shown), the dirt attached to the surface of the cleaning cloth 7 is rubbed off, thereby preventing the dirt from adhering to and affecting the subsequent cleaning work on the surface of the power generation panel;

[0059] When the circular surface of the lifting wheel 23 is separated from the push rod 24, that is, when the cross section of the lifting wheel 23 is parallel to the push rod 24, the push rod 24 will drop rapidly under its own weight, and the first friction wheel 26 will be separated from the second friction wheel 27, and the second friction wheel 27 will stop rotating. The first rack rod 17 will be quickly reset under the action of the third spring 19, and the support rod 28 will quickly pull the push plate 29 to reset to the initial position (in actual use, the push plate 29 and the slide plate 2 can also be fixedly connected to a spring for auxiliary reset), then the fourth spring 3 1 will quickly push the wedge block 30 to reset, and at this time the wedge block 30 will no longer push the clamping rod 32 to clamp the cleaning cloth 7, that is, the cleaning cloth 7 is in a free state, then when the top rod 24 descends, the T-bar 34 will also descend, and will force the cleaning cloth 7 to descend a short distance through the ratchet piece 36 (when the ratchet piece 36 and the cross bar 33 rise, the ratchet piece 36 will rise along the surface of the cleaning cloth 7, but when the ratchet piece 36 descends, the torsion spring 41 can make the bottom end of the ratchet piece 36 close to the cleaning cloth 7 and drive the cleaning cloth 7 to descend), thereby pulling the annular The cleaning cloth 7 can rotate slightly, so that the cleaning cloth 7 in the rubbed area between the movable rod 15 and the fixed rod 14 can be replaced. On the one hand, the position of the next rubbing can be replaced, and on the other hand, the position of the cleaning cloth 7 below the contact member 5 that is in contact with the surface of the power generation board can be replaced. When the cleaning cloth 7 is replaced, if the contact member 5 is in a state of compressing the first spring 6, it means that the cleaning cloth 7 at the bottom is in contact with the surface of the power generation board, which may affect the smooth replacement of the cleaning cloth 7. Therefore, if the cleaning cloth 7 is replaced when the top rod 24 descends, When the cleaning cloth 7 is in contact with the surface of the power generation board, the lowering of the top rod 24 will not immediately drive the cleaning cloth 7 to be replaced through the spine 36, but when the cleaning cloth 7 is in contact with the surface of the power generation board, the spine 36 will not be able to pull the cleaning cloth 7 to move. At this time, the T-shaped rod 34 will slide up along the top rod 24 and stretch the fifth spring 35 until the contact member 5 and the set 4 swing to the maximum extent, that is, the cleaning cloth 7 is no longer blocked after the contact member 5 is out of contact with the surface of the power generation board. Then the elastic reset of the fifth spring 35 will drive the T-shaped rod 34 to descend, and then the spine 36 will drive the cleaning cloth 7 to change its position;

[0060] The cleaning cloth 7 in the middle of the thorn pieces 36 can be restricted by the second resisting rod 39, so that the cleaning cloth 7 can always remain in a vertical state, which is convenient for the two thorn pieces 36 to pull the cleaning cloth 7 when they are descending. Fig.12 As shown, in actual use, the distance between the second resistance rod 39 and the set 4 is relatively long, so that the set 4 will not contact the second resistance rod 39 after swinging to the maximum extent, so as to avoid the second resistance rod 39 affecting the swing of the set 4;

[0061] The first resisting rod 37 can be arranged to squeeze the first resisting rod 37 when the cleaning cloth 7 below is stretched during the process of the movable rod 15 being attached to the fixed rod 14 and rising, so that the first resisting rod 37 can slide along the side wall of the set 4 and compress the sixth spring 38, thereby adapting to the lifting and lowering of the movable rod 15, and when the contact member 5 slides along the inside of the set 4, the cleaning cloth 7 is driven to shrink into the inside of the set 4 by the third resisting rod 40, and the sliding of the first resisting rod 37 can adapt to the shrinkage of the cleaning cloth 7;

[0062] When the lifting wheel 23 lifts the push rod 24 again, the push rod 24 will rise again, and then the subsequent work will be carried out again, and a cycle will be generated to continuously rub and replace the cleaning cloth 7.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
