Dust-proof photovoltaic module

Abstract

The application discloses a dustproof photovoltaic module and belongs to the technical field of photovoltaic modules. The dustproof photovoltaic module is characterized in that a transmission assembly is installed on the left and right sides of a photovoltaic panel. The transmission assembly facilitates the automatic cleaning of the sponge pad at regular time intervals under the electric program. During this period, the water storage assembly is used for storing rainwater under daily rainfall weather, so that the sponge pad can have a corresponding amount of aqueous solution during the cleaning work. In addition, under the condition of no rainfall, the water storage assembly stores part of the aqueous solution formed by the water dew under the day-night temperature difference, which is used for daily cleaning work. The assembly for releasing the hydrophobic solution and the cleaning solution synchronously transports the hydrophobic solution and the cleaning solution into the sponge pad, so that the sponge pad can clean the surface of the photovoltaic panel more thoroughly. The hydrophobic solution can prevent the rainwater and the dew from being easily attached to the surface of the photovoltaic panel under rainfall weather and in the early morning, so that the photovoltaic panel can always maintain a clean surface.

Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, and more specifically, to a dustproof photovoltaic module. Background Technology

[0002] In recent years, the photovoltaic power generation industry has flourished, and a large number of solar photovoltaic power stations have been built in rural and mountainous areas across the country. One problem encountered in the maintenance and operation of solar photovoltaic power stations is the cleaning of the photovoltaic panel surface. During the long-term operation of the power station, birds, bird droppings, dust, fallen leaves and other obstructions inevitably fall on the solar cell modules. These obstructions form shadows on the solar cell modules, causing changes in the current and voltage of some individual cells in the solar cell modules.

[0003] This results in an increase in the product of local current and voltage in the solar cell modules, leading to localized temperature rises. Therefore, maintaining the cleanliness and dust prevention of the solar panel surface is crucial during the later stages of photovoltaic power plant operation. Obstructions caused by bird droppings, dust, fallen leaves, and other debris can generate hot spot effects, which can range from affecting power generation to causing localized damage to the cells and shortening the lifespan of the modules. Regular cleaning and maintenance of the photovoltaic panels are essential to maintain power generation efficiency. According to estimates from international organizations, each cleaning of photovoltaic panels can increase power generation by approximately 10% to 30%. Therefore, this invention proposes a dust-proof photovoltaic module to improve power generation efficiency. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the present invention aims to provide a dustproof photovoltaic module. This solution involves installing transmission components on both sides of the photovoltaic panel, enabling the sponge pad to automatically clean itself periodically under an electric program. During this time, a water storage component accumulates rainwater from daily rainfall, ensuring the sponge pad has a corresponding amount of aqueous solution for cleaning the photovoltaic panel surface. Simultaneously, in dry weather, the water storage component accumulates dew formed due to diurnal temperature variations for daily cleaning. Furthermore, components releasing hydrophobic and cleaning solutions simultaneously deliver these solutions into the sponge pad, resulting in a more thorough cleaning of the photovoltaic panel surface. The hydrophobic solution prevents rainwater and dew from adhering to the photovoltaic panel surface during rainy weather and in the early morning, ensuring the photovoltaic panel remains clean. Consequently, during daily use, the photovoltaic panel surface remains unobstructed and smooth, allowing for better sunlight absorption and improved power generation efficiency.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Example:

[0034] Please see Figure 1-9 A dustproof photovoltaic module includes a support base 1, a photovoltaic panel 2 fixedly connected to the upper end of the support base 1, connecting blocks 3 fixedly connected to both the left and right ends of the photovoltaic panel 2, a transmission component 4 inside the connecting blocks 3, a drive component 5 at the top of the photovoltaic panel 2, a sponge pad 7 fixedly connected to the upper end of the transmission component 4, and a water storage component 6 at the upper end of the sponge pad 7.

[0035] To prevent bird droppings, dust, and fallen leaves from accumulating on the surface of the photovoltaic panel 2 during prolonged use, thus reducing sunlight exposure and weakening the current and voltage of individual cells and lowering power generation efficiency, this embodiment installs connecting blocks 3 on both sides of the photovoltaic panel 2. A transmission component 4 is installed on the inner wall of the connecting blocks 3, and a sponge pad 7 and a component for releasing hydrophobic and cleaning solutions are connected above the transmission component 4. This enables automatic periodic operation under an electric program, for example, driving the transmission component 4 every 12 hours. During this period, the water storage component 6 collects rainwater from daily rainfall. The sponge pad 7 provides a corresponding amount of aqueous solution for cleaning the surface of the photovoltaic panel 2 during cleaning operations. Simultaneously, in dry weather, the water storage component 6 accumulates some aqueous solution under the dew formed by the diurnal temperature difference for daily cleaning. While the sponge pad 7 slides to clean the surface of the photovoltaic panel 2, its components simultaneously deliver the hydrophobic and cleaning solutions into the sponge pad 7. The released cleaning solution helps the sponge pad 7 clean the surface of the photovoltaic panel 2 more thoroughly, while the hydrophobic solution prevents rainwater and dew from adhering to the surface of the photovoltaic panel 2 during rainy weather and in the early morning, keeping the photovoltaic panel 2 clean at all times. Therefore, during daily use, the surface of the photovoltaic panel 2 remains unobstructed and smooth, allowing for better sunlight exposure and improved power generation efficiency.

[0036] Please see Figure 1-2 The connecting block 3 has water seepage holes 31 on both the side and bottom ends, with the water seepage holes 31 on the side ends located on the upper and lower sides of the transmission assembly 4.

[0037] During use, this solution allows rainwater to flow out through the seepage holes 31 during normal rainy weather, preventing rainwater from accumulating inside the connecting block 3 for a long time and causing scale, moss, and other phenomena to form inside.

[0038] Please see Figure 1 and Figure 3 The transmission component 4 includes a slide groove 41 opened at the upper end of the connecting block 3. A slider 42 is slidably connected between the inner walls of the slide groove 41. A threaded groove 43 is opened at the outer end of the slider 42. A threaded rod 44 is threadedly connected between the inner walls of the threaded groove 43. The bottom end of the threaded rod 44 is rotatably connected to the inner wall of the slide groove 41. A tension spring 45 is fixedly connected between the slider 42 and the bottom inner wall of the slide groove 41. The tension spring 45 is sleeved on the outside of the threaded rod 44.

[0039] During use, when the threaded rod 44 rotates under the drive of the upper drive component 5, the threaded rod 44, being a screw rod with a single thread, is similar to a nut on a rod that can move in one direction. In this solution, under the limiting action of the slide groove 41, the threaded rod 44 can be converted into linear motion during its rotation. This causes the slider 42 to slide within the slide groove 41 through the threaded rod 44, thereby driving the sponge pad 7 connected above the slider 42 to move upwards synchronously, prompting the sponge pad 7 to clean the dust and debris on the surface of the photovoltaic panel 2.

[0040] Please see Figure 1 and Figure 4 The drive assembly 5 includes a protective shell 51 fixedly connected to the top of the photovoltaic panel 2. A support rod 52 is fixedly connected to the center of the inner bottom end of the protective shell 51. A first connecting rod 53 is fixedly connected to the upper end of the support rod 52. A first bevel gear 54 is rotatably connected to both the left and right ends of the first connecting rod 53. A second connecting rod 55 is fixedly connected to the outer end of the first bevel gear 54. A second bevel gear 56 is fixedly connected to the other end of the second connecting rod 55. A third bevel gear 57 is provided on the upper side of the first connecting rod 53. The third bevel gear 57 is located between the inner walls of the two first bevel gears 54 and meshes with the first bevel gears 54. A motor 58 is installed on the upper end of the third bevel gear 57. The motor 58 is located on the outer side of the protective shell 51. A fourth bevel gear 59 is meshed with the outer end of the second bevel gear 56. The fourth bevel gear 59 is fixedly connected to the transmission assembly 4.

[0041] During use, when the sponge pad 7 needs to be driven for cleaning, its motor 58 is started at set intervals, such as every 12 hours. When the motor 58 starts, its output drives the third bevel gear 57 below to rotate synchronously. While the third bevel gear 57 rotates on the horizontal axis, it drives the two first bevel gears 54 and the connected second bevel gear 56 to transmit power, causing the first bevel gears 54 and the second bevel gear 56 to transmit power on the vertical plane. Then, under the transmission of the second bevel gear 56, the fourth bevel gear 59 connected to the threaded rod 44 rotates, causing the threaded rods 44 on both sides below to transmit power simultaneously, causing the sponge pad 7 to move downward. The motor 58 receives the power value and stops supplying power when the sponge pad 7 moves to the bottom of the photovoltaic panel 2 to reduce power consumption. Then, the sponge pad 7 rebounds under the tension spring 45 wrapped on the surface of the threaded rod 44, causing the sponge pad 7 to return to its initial position.

[0042] Please see Figure 1 and Figure 5The water storage component 6 includes a water storage box 61 fixedly connected to the upper end of a sponge pad 7. A water storage tank 62 is provided at the upper end of the water storage box 61. A metal organic frame 63 is provided between the inner walls of the water storage tank 62. A limiting component 64 is provided between the metal organic frame 63 and the water storage box 61. A plurality of evenly distributed water outlet holes 65 are provided at the inner bottom end of the water storage tank 62. A hydrophobic water release component 66 is provided between the inner walls of the water outlet holes 65. A cleaning liquid release component 67 is provided at the bottom end of the water storage box 61.

[0043] During use, in rainy weather, rainwater enters the water storage tank 62 through the metal organic frame 63 and flows into the outlet hole 65. In the outlet hole 65, the rainwater comes into contact with the hydrophobic solution release component 66, thereby releasing the hydrophobic solution inside. The rainwater then flows to the surface of the sponge pad 7. As the sponge pad 7 moves, its surface is initially lower than the surface of the photovoltaic panel 2. When the sponge pad 7 moves to the surface of the photovoltaic panel 2, the squeezing force causes the sponge pad 7 to contract upwards. Under the action of squeezing force, the cleaning solution release component 67 is compressed, releasing the cleaning solution inside. Thus, the sponge pad 7, having absorbed the cleaning solution and hydrophobic solution, cleans the surface of the photovoltaic panel 2. At the same time, a hydrophobic coating is applied to the surface of the photovoltaic panel 2 to prevent rainwater from sticking to the wall.

[0044] Meanwhile, the metal-organic framework 63 in this solution, being a porous material, can effectively absorb moisture from the air. Under heating conditions, the absorbed moisture can be released, thus absorbing water molecules generated by the diurnal temperature difference. During the day, the moisture is released again through heat, thereby meeting the daily moisture supply when there is no rain. This allows the sponge pad 7 to wipe the surface of the photovoltaic panel 2 once or multiple times a day.

[0045] Please see Figure 1 and Figure 5-6 The limiting component 64 includes a rectangular groove 641 opened at the upper end of the water storage box 61. The rectangular groove 641 is located on the right side of the water storage tank 62. A support block 642 is provided between the inner walls of the rectangular groove 641. The support block 642 is fixedly connected to the metal organic frame 63. Threaded holes 643 are opened at the outer ends of the support block 642 and the water storage box 61. Studs 644 are threadedly connected between the inner walls of the threaded holes 643.

[0046] During use, when the hydrophobic water release component 66 inside the water outlet 65 needs to be replaced, it can be removed from the threaded hole 643 by rotating the threaded stud 644, causing the support block 642 to disengage from the rectangular groove 641. Then, the metal organic frame 63 and the support block 642 can be removed. Subsequently, the hydrophobic water release component 66 can be replaced by rotating the threaded stud 644. This facilitates the continued automatic cleaning work and also helps to clean the debris attached to the surface of the metal organic frame 63, preventing the metal organic frame 63 from becoming blocked and rainwater from flowing in.

[0047] Please see Figure 1 , Figure 5 and Figure 7 The hydrophobic water release component 66 includes a threaded sleeve 661 threaded between the inner walls of the water outlet 65, a water-absorbing and shrinking balloon 662 provided between the inner walls of the threaded sleeve 661, a traction rope 663 fixedly connected between the water-absorbing and shrinking balloon 662 and the inner wall of the threaded sleeve 661, a plurality of evenly distributed through holes 664 opened at the outer end of the water-absorbing and shrinking balloon 662, a sealing film 665 fixedly connected between the inner walls of the through holes 664, and the interior of the water-absorbing and shrinking balloon 662 is filled with a polymer hydrophobic water solution 666.

[0048] The sealing film 665 is made based on the principle of heart valves, and its initial shape is a closed shape. The deformation direction of the sealing film 665 is from the inside to the outside.

[0049] During use, when rainwater flows into the outlet 65, it comes into contact with the water-absorbing and shrinking balloon 662, causing the balloon to shrink. Due to the air pressure sealing inside the balloon 662, the pressure forces the sealing film 665 to open to the outside, thereby releasing the polymer hydrophobic water solution 666 from inside the balloon 662. As the rainwater flows to the surface of the sponge pad 7, the balloon 662 returns to its initial shape when there is no water contact.

[0050] Please see Figure 1 , Figure 5 and Figure 8 The cleaning fluid release assembly 67 includes a liquid storage tank 671 at the bottom of a water storage box 61, an elastic membrane 672 fixedly connected between the inner walls of the liquid storage tank 671, a rubber sealing piece 673 embedded at the lower center of the elastic membrane 672, a column 674 fixedly connected at the top center of the liquid storage tank 671, and a plurality of evenly distributed connecting holes 675 at the outer end of the column 674. The space between the liquid storage tank 671 and the elastic membrane 672 is filled with cleaning fluid 676.

[0051] During use, the surface of the sponge pad 7 is initially lower than the surface of the photovoltaic panel 2. When the sponge pad 7 moves to the surface of the photovoltaic panel 2, the squeezing force causes the sponge pad 7 to contract upwards, thereby pressing the elastic film 672 and causing it to move upwards. At the same time, the elastic film 672 is squeezed to release the solution inside the cleaning liquid 676. Since the surface of the column 674 has multiple connecting holes 675, the column 674 contains the cleaning liquid 676. When the elastic film 672 is pressed and is at the same level as the bottom of the water storage box 61, the column 674 abuts against the rubber seal 673, causing the cleaning liquid 676 inside to be released into the sponge pad 7. Then, under the adsorption and diffusion properties of the sponge pad 7, the cleaning liquid 676 is distributed throughout the entire sponge pad 7. Finally, the sponge pad 7, mixed with the cleaning liquid 676, cleans the surface of the photovoltaic panel 2.

[0052] Please see Figure 1 , Figure 5 and Figure 8 The water storage box 61 has a filling groove 677 on its side end. The filling groove 677 is connected to the liquid storage tank 671. A partition 678 is rotatably connected between the inner walls of the liquid storage tank 671. The partition 678 is made using the principle of a one-way valve and its deformation direction is from the outside to the inside. A plug 679 is threaded between the inner walls of the filling groove 677. The plug 679 is located on the outside of the water storage box 61.

[0053] During use, when the cleaning fluid 676 is depleted, the operator can open the plug 679 by rotating the thread, then push the partition 678 open by inserting a tube and extending it into the reservoir 671. After that, the updated cleaning fluid 676 is introduced into the reservoir 671 to complete the replenishment of the cleaning fluid 676.

[0054] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
