Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaics, and specifically relates to a cleaning device with variable flow rate in zones based on photovoltaic power supply. Background Art

[0002] The technology of variable flow rate in zones for a photovoltaic power generation system is a method for optimizing the performance and efficiency of a photovoltaic power generation system; this technology divides the entire photovoltaic system into multiple zones, and independently adjusts and manages the current in each zone, thereby achieving the maximum utilization of energy and the improvement of system stability; dust, dirt, etc. on the surface of photovoltaic panels will block light from entering the battery cells, reducing the photoelectric conversion efficiency. Cleaning can remove these obstacles to ensure that more light can shine on the photovoltaic panels, thereby increasing power generation; currently, the cleaning of photovoltaic panels mainly uses the method of water flushing. Although this method can effectively remove dust and dirt on the surface of photovoltaic panels to a certain extent, there are obvious limitations in practical applications. First of all, water flushing requires a large amount of water resources. Especially in large-scale photovoltaic power stations, the daily water consumption is huge, which is particularly prominent in areas with water shortages. This not only increases the operating cost but also causes greater pressure on the environment. Secondly, frequent water flushing operations are prone to leave water stains on the surface of photovoltaic panels, and long-term accumulation may have a negative impact on the light transmission performance of photovoltaic panels. Therefore, a cleaning device with variable flow rate in zones based on photovoltaic power supply is proposed. Summary of the Invention

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] In the present invention, the driving motor drives the second roller, the conveyor belt, the second magnet and the cleaning cloth to rotate. The cleaning cloth will rotate to the top of the photovoltaic panel. At this time, one end of the cleaning cloth contacts the top of the photovoltaic panel and moves along with the conveyor belt to clean the dust on the top of the photovoltaic panel. Since the cleaning cloth absorbs water, it can improve the cleaning effect of the dust on the top of the photovoltaic panel. And the cleaning cloth continuously moves along with the conveyor belt through the top of the photovoltaic panel and will enter the inside of the cleaning assembly to clean the dust on the cleaning cloth. In this way, the dust on the top of the photovoltaic panel is cleaned by the cleaning cloth adsorbing clean water, reducing the water consumption for cleaning the photovoltaic panel;

[0030] In the present invention, the second magnet and the cleaning cloth move along with the conveyor belt. The second magnet moves to the bottom of the first magnet. At this time, the first magnet is attracted by the magnetic force of the second magnet to make contact. During the downward movement of the first magnet, it drives the connecting plate to move downward along the limiting rod and compress the elastic piece. At the same time, the pressing plate moves downward to apply pressure to the cleaning cloth, so that one end of the cleaning cloth contacts the top of the photovoltaic panel, increasing the friction between the cleaning cloth and the photovoltaic panel, and thus improving the cleaning effect of the cleaning cloth on the dust on the top of the photovoltaic panel;

[0031] In the present invention, the second magnet and the cleaning cloth enter the interior of the cleaning tank and pass between two arc-shaped plates. The cleaning cloth is squeezed and combed by the two arc-shaped plates and the bumps, so that the stains on the cleaning cloth fall into the interior of the cleaning tank. The second magnet and the cleaning cloth sequentially enter between two clamping plates. The second roller drives the connecting member to push the transmission frame, the connecting rod and the clamping plates to move left and right. Since the distance between the two clamping plates gradually decreases from top to bottom, it can ensure that the second magnet and the cleaning cloth can normally enter between the two clamping plates, and the cleaning cloth swings in the water in the cleaning tank, thereby realizing the cleaning of the cleaning cloth and ensuring that the photovoltaic panel can be cleaned cyclically.

Detailed implementation manner

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figures 1 to 9 shown, the present invention provides a cleaning device with variable flow rate in zones based on photovoltaic power supply, including a fixing frame 1, and further including:

[0044] A support component 3, and the support component 3 is supported by the fixing frame 1 and the cleaning component 5;

[0045] An applying component 2, and the applying component 2 is arranged on the support component 3;

[0046] A cleaning component 6, and the cleaning component 6 is installed on the support component 3 and the cleaning component 5;

[0047] Among them, the support component 3 includes a water storage tank 35 fixedly installed on the top of the fixing frame 1, two first support plates 31 fixedly installed on the side of the cleaning box 51 in the cleaning component 5, a support ring 34 fixedly installed on the side of the other end of the first support plate 31, a guide rod 33 and a second support plate 37 fixedly installed between the support ring 34 and the cleaning box 51, and a guide groove 38 is opened on the second support plate 37;

[0048] The cleaning component 6 includes a first roller 61 sleeved on the support ring 34 and the other end of the first support plate 31. A support roller 65 and a second roller 66 are arranged inside the cleaning tank 51. Transmission belts 64 are sleeved on both ends of the first roller 61, the support roller 65 and the second roller 66. A second magnet 62 is fixedly installed between the two transmission belts 64. A cleaning cloth 63 is fixedly installed on the side of the second magnet 62. The cleaning cloth 63 is made of cotton material;

[0049] The top of the water storage tank 35 is arc-shaped, and the upper end of the water storage tank 35 is located outside the first roller 61;

[0050] In the initial state, the cleaning cloth 63 is located at the upper end of the water storage tank 35, and the cleaning cloth 63 covers the tank opening 36. The inside of the water storage tank 35 is filled with water;

[0051] A photovoltaic panel 32 is fixedly installed between the two first support plates 31;

[0052] A driving motor for driving the second roller 66 is fixedly installed outside the cleaning tank 51;

[0053] The second roller 66 drives the transmission belt 64, the second magnet 62 and the cleaning cloth 63 to rotate. One end of the cleaning cloth 63 contacts the top of the photovoltaic panel 32.

[0054] By injecting water into the water storage tank 35, the water surface in the water storage tank 35 is kept level with the tank opening 36. Since the cleaning cloth 63 is initially located on the tank opening 36, the cleaning cloth 63 absorbs water. When the photovoltaic panel 32 needs to be cleaned, the driving motor drives the second roller 66, the transmission belt 64, the second magnet 62 and the cleaning cloth 63 to rotate. The cleaning cloth 63 will rotate to the top of the photovoltaic panel 32. At this time, one end of the cleaning cloth 63 contacts the top of the photovoltaic panel 32 and moves along with the transmission belt 64 to clean the dust on the top of the photovoltaic panel 32. Since the cleaning cloth 63 absorbs water, it can improve the cleaning effect of the dust on the top of the photovoltaic panel 32 and ensure the power generation of the photovoltaic panel 32;

[0055] The cleaning cloth 63 continuously moves along with the transmission belt 64 through the top of the photovoltaic panel 32 and will enter the inside of the cleaning component 5 to clean the dust on the cleaning cloth 63. In this way, the cleaning cloth 63 adsorbs clear water to clean the dust on the top of the photovoltaic panel 32, reducing the water consumption for cleaning the photovoltaic panel 32, being applicable to areas with water shortage, and at the same time being able to avoid waste of water resources and reduce the operation cost.

[0056] In this specification, limit rings for limiting the transmission belt 64 are arranged at both ends of the support roller 65, the second roller 66 and the first roller 61. At the same time, the second roller 66, the support roller 65, the first roller 61 and the transmission belt 64 can be replaced by a chain and a gear without deviating from the present application.

[0057] Such as Figures 2 - 7As shown, the application component 2 includes a sliding block 24 that slides outside the guide rod 33. The sliding block 24 passes through the guide groove 38, and a support frame 26 is fixedly installed on the top of the sliding block 24. The support frame 26 is located on the top of the second support plate 37;

[0058] A limiting rod 25 is fixedly installed inside the support frame 26. A connecting plate 28 is movably arranged on the limiting rod 25, and an elastic piece 29 for upwardly propping the connecting plate 28 is arranged on the support frame 26;

[0059] A first magnet 27 is fixedly installed on the connecting plate 28, and a pressing plate 20 is fixedly installed on the side of the first magnet 27;

[0060] One end of the pressing plate 20 is level with the photovoltaic panel 32, and the height of one end of the pressing plate 20 is lower than that of the first magnet 27;

[0061] When the second magnet 62 and the cleaning cloth 63 move to the bottom of the first magnet 27 following the conveyor belt 64, the first magnet 27 drives the pressing plate 20 to move downward under the action of the magnetic force of the second magnet 62, and presses the cleaning cloth 63 through the pressing plate 20, increasing the friction between the cleaning cloth 63 and the photovoltaic panel 32.

[0062] As the second magnet 62 and the cleaning cloth 63 move following the conveyor belt 64, the second magnet 62 moves to the bottom of the first magnet 27. At this time, the first magnet 27 is attracted by the magnetic force of the second magnet 62 and makes contact. During the downward movement of the first magnet 27, it drives the connecting plate 28 to move downward along the limiting rod 25 and compress the elastic piece 29. At the same time, the pressing plate 20 moves downward to apply pressure to the cleaning cloth 63, making one end of the cleaning cloth 63 contact the top of the photovoltaic panel 32, increasing the friction between the cleaning cloth 63 and the photovoltaic panel 32, thereby improving the cleaning effect of the cleaning cloth 63 on the dust on the top of the photovoltaic panel 32. At the same time, the first magnet 27, the support frame 26, and the sliding block 24 move along the guide rod 33 and the second support plate 37 to comprehensively clean the top of the photovoltaic panel 32.

[0063] At the same time, by pressing the cleaning cloth 63 through the pressing plate 20, water stains can be prevented from remaining on the top of the photovoltaic panel 32 during the movement of the cleaning cloth 63 on the top of the photovoltaic panel 32, and dust can be prevented from adhering to the photovoltaic panel 32 through the water stains on the top of the photovoltaic panel 32, reducing the cleaning effect of the photovoltaic panel 32.

[0064] As Figure 7 shown, an arc-shaped groove 21 is formed on the support ring 34, and one end of the sliding block 24 is connected with a counterweight 23 through a connecting rope 22;

[0065] The connecting rope 22 slides inside the arc-shaped groove 21.

[0066] During the process of driving the first magnet 27, the support frame 26 and the sliding block 24 by the second magnet 62, the sliding block 24 pulls the counterweight 23 upward through the connecting rope 22, and the arc groove 21 limits the connecting rope 22. When the support frame 26 moves to the end close to the cleaning tank 51, the support frame 26 is blocked by the cleaning tank 51. At this time, the second magnet 62 is separated from the first magnet 27. At this time, the conveyor belt 64 drives the second magnet 62 and the cleaning cloth 63 into the cleaning tank 51, while the support frame 26 and the sliding block 24 move in the opposite direction and reset along the second support plate 37 and the guide rod 33 under the action of the weight of the counterweight 23. After the cleaning cloth 63 rotates one week, the dust on the top of the photovoltaic panel 32 can be cleaned cyclically.

[0067] As Figure 8 shown in Figure 9 Figure, the cleaning assembly 5 includes two arc-shaped plates 55 fixedly installed inside the cleaning tank 51. Convex blocks 56 are arranged on the opposite surfaces of the two arc-shaped plates 55, and the inside of the cleaning tank 51 is filled with water;

[0068] The two arc-shaped plates 55 are located on both sides of the conveyor belt 64. The conveyor belt 64 drives the second magnet 62 and the cleaning cloth 63 into the cleaning tank 51 and will pass between the two arc-shaped plates 55;

[0069] The cleaning assembly 5 further includes connecting rods 53 movably sleeved on both sides of the cleaning tank 51. A transmission frame 52 is fixedly installed on the outside of the connecting rod 53, and the transmission frame 52 is movably sleeved on the outside of the cleaning tank 51;

[0070] Clamping plates 54 are fixedly installed at the opposite ends of the two connecting rods 53. The clamping plates 54 and the arc-shaped plates 55 are kept vertical, and the gap between the two clamping plates 54 gradually decreases from top to bottom;

[0071] A docking rod 58 is fixedly installed on the outside of the transmission frame 52. One end of the second roller 66 is eccentrically sleeved with a connecting member 59, and a rectangular groove 50 for the docking rod 58 to move is opened at the upper end of the connecting member 59.

[0072] By driving the second roller 66, the support roller 65, the first roller 61 and the conveyor belt 64 to move by the driving motor, during the movement, the second magnet 62 and the cleaning cloth 63 enter the inside of the cleaning tank 51 and pass between the two arc-shaped plates 55. The cleaning cloth 63 is squeezed and combed by the two arc-shaped plates 55 and the convex blocks 56, so that the stains on the cleaning cloth 63 fall into the inside of the cleaning tank 51. The second magnet 62 and the cleaning cloth 63 sequentially enter between the two clamping plates 54;

[0073] Meanwhile, since the connecting member 59 is eccentrically connected to the second roller 66, and a guide block for vertically moving the connecting member 59 is provided on the side of the transmission frame 52, the connecting member 59 is driven by the second roller 66 to push the transmission frame 52, the connecting rod 53 and the clamping plate 54 to move left and right. Since the distance between the two clamping plates 54 gradually decreases from top to bottom, it can ensure that the second magnet 62 and the cleaning cloth 63 can normally enter between the two clamping plates 54, so that the cleaning cloth 63 swings in the water in the cleaning tank 51, thereby realizing the cleaning of the cleaning cloth 63 and ensuring that the photovoltaic panel 32 can be cleaned cyclically.

[0074] Meanwhile, the bottom of the cleaning tank 51 can be designed in a funnel shape, and the stains cleaned by the cleaning cloth 63 will precipitate at the bottom of the cleaning tank 51, which is convenient for the discharged sediment sludge and can ensure the cleanliness of the water in the cleaning tank 51.

[0075] Such as Figure 4 And Figure 8 As shown, the water storage tank 35 and the cleaning tank 51 are connected through a water conduit 311, and the inside of the cleaning tank 51 blocks the water conduit 311 through a float valve 312.

[0076] After discharging the sediment sludge in the cleaning tank 51, the water level in the cleaning tank 51 drops. At this time, the float valve 312 moves downward, and the water in the water storage tank 35 enters the inside of the cleaning tank 51 through the water conduit 311 to ensure the water level in the cleaning tank 51.

[0077] The working principle and usage process of the present invention:

[0078] By injecting water into the water storage tank 35, the water surface in the water storage tank 35 is kept level with the tank opening 36. Since the cleaning cloth 63 is initially located on the tank opening 36, the cleaning cloth 63 absorbs water. When the photovoltaic panel 32 needs to be cleaned, the drive motor drives the second roller 66, the transmission belt 64, the second magnet 62 and the cleaning cloth 63 to rotate. The cleaning cloth 63 will rotate to the top of the photovoltaic panel 32. At this time, one end of the cleaning cloth 63 contacts the top of the photovoltaic panel 32 and moves along with the transmission belt 64 to clean the dust on the top of the photovoltaic panel 32. Since the cleaning cloth 63 absorbs water, it can improve the cleaning effect of the dust on the top of the photovoltaic panel 32 and ensure the power generation of the photovoltaic panel 32;

[0079] The second magnet 62 and the cleaning cloth 63 move along with the conveyor belt 64. When the second magnet 62 moves to the bottom of the first magnet 27, the first magnet 27 is attracted by the magnetic force of the second magnet 62 and comes into contact with it. During the downward movement of the first magnet 27, the connecting plate 28 is driven to move downward along the limiting rod 25 and compress the elastic piece 29. At the same time, the pressing plate 20 moves downward to apply pressure to the cleaning cloth 63, so that one end of the cleaning cloth 63 contacts the top of the photovoltaic panel 32, increasing the friction between the cleaning cloth 63 and the photovoltaic panel 32, thereby improving the cleaning effect of the cleaning cloth 63 on the dust on the top of the photovoltaic panel 32. At the same time, the first magnet 27, the support frame 26 and the sliding block 24 move along the guide rod 33 and the second support plate 37 to clean the top of the photovoltaic panel 32 comprehensively. At the same time, by pressing the cleaning cloth 63 with the pressing plate 20, water stains can be prevented from remaining on the top of the photovoltaic panel 32 during the movement of the cleaning cloth 63 on the top of the photovoltaic panel 32, and dust can be prevented from adhering to the photovoltaic panel 32 through the water stains on the top of the photovoltaic panel 32, reducing the cleaning effect of the photovoltaic panel 32;

[0080] During the process of the second magnet 62 driving the first magnet 27, the support frame 26 and the sliding block 24 to move, the sliding block 24 pulls the counterweight 23 to move upward through the connecting rope 22, and the arc-shaped groove 21 limits the connecting rope 22. When the support frame 26 moves to the end close to the cleaning tank 51, the support frame 26 is blocked by the cleaning tank 51. At this time, the second magnet 62 is separated from the first magnet 27. At this time, the conveyor belt 64 drives the second magnet 62 and the cleaning cloth 63 into the cleaning tank 51, while the support frame 26 and the sliding block 24 move in the reverse direction and reset along the second support plate 37 and the guide rod 33 under the action of the weight of the counterweight 23. After the cleaning cloth 63 rotates one week, the dust on the top of the photovoltaic panel 32 can be cleaned cyclically;

[0081] The driving motor drives the second roller 66, the support roller 65, the first roller 61 and the conveyor belt 64 to move. During the movement, the second magnet 62 and the cleaning cloth 63 enter the inside of the cleaning tank 51 and pass between the two arc-shaped plates 55. The two arc-shaped plates 55 and the convex blocks 56 squeeze and comb the cleaning cloth 63, so that the stains on the cleaning cloth 63 fall into the inside of the cleaning tank 51, and the second magnet 62 and the cleaning cloth 63 enter between the two clamping plates 54 in turn;

[0082] At the same time, since the connecting piece 59 is eccentrically connected to the second roller 66, and the side part of the transmission frame 52 is provided with a guide block for the vertical movement of the connecting piece 59, the second roller 66 drives the connecting piece 59 to push the transmission frame 52, the connecting rod 53 and the clamping plate 54 to move left and right. Since the distance between the two clamping plates 54 gradually decreases from top to bottom, it can ensure that the second magnet 62 and the cleaning cloth 63 can normally enter between the two clamping plates 54, so that the cleaning cloth 63 swings in the water in the cleaning tank 51, thereby realizing the cleaning of the cleaning cloth 63;

[0083] After the sludge precipitated in the cleaning tank 51 is discharged, the water level in the cleaning tank 51 drops. At this time, the float valve 312 moves downward, and the water in the water storage tank 35 enters the inside of the cleaning tank 51 through the water guide pipe 311 to ensure the water level in the cleaning tank 51.
