Description

Technical Field

[0001] This invention relates to the field of photovoltaic module decontamination technology, specifically a self-draining photovoltaic module decontamination device for rainy days. Background Technology

[0002] Photovoltaic modules, as the core component of solar power generation systems, are widely used in outdoor environments. Their power generation efficiency directly depends on the cleanliness of the photovoltaic panel surface. Outdoor photovoltaic panels are exposed to the natural environment for extended periods, making them susceptible to the accumulation of dirt, sand, bird droppings, fallen leaves, and other contaminants. These contaminants block sunlight, reducing the light transmittance of the photovoltaic panels and consequently decreasing their power generation efficiency. Long-term accumulation can also accelerate the aging of the photovoltaic panel surface, shortening the module's lifespan. Therefore, regular cleaning of photovoltaic modules is crucial for ensuring the stable and efficient operation of photovoltaic power generation systems.

[0003] Currently, existing methods for cleaning photovoltaic modules are mainly divided into two categories: manual cleaning and power-driven cleaning. Among them, manual cleaning is the most traditional method, which usually requires operators to use elevated equipment to wipe and rinse the surface of the photovoltaic panels. This method not only consumes a lot of labor costs and has low cleaning efficiency, but also poses high labor intensity and operational risks for cleaning large-area photovoltaic modules in large photovoltaic power plants, making it difficult to achieve comprehensive and rapid cleaning and failing to meet the cleaning needs of large-scale photovoltaic modules.

[0004] On the other hand, power-driven cleaning devices mainly rely on electric or hydraulic power mechanisms to drive cleaning components to clean the surface of photovoltaic panels. However, such power-driven cleaning devices have obvious drawbacks: firstly, the power mechanism makes the device structure complex and the manufacturing cost high, and it requires additional electrical or other energy during operation, increasing the overall energy consumption of the photovoltaic power generation system; secondly, the power mechanism operates in an outdoor environment for a long time, making it susceptible to malfunctions due to rain, dust, etc., resulting in high maintenance difficulty and cost, and the occurrence of malfunctions will cause cleaning operations to be interrupted, making it impossible to guarantee the continuous cleaning of photovoltaic modules.

[0005] In summary, existing methods for cleaning photovoltaic modules suffer from problems such as low cleaning efficiency, high cost, high energy consumption, inconvenient maintenance, poor cleaning effect, impact on photovoltaic panel transmittance, and unstable installation. They cannot simultaneously achieve key indicators such as cleaning effect, operational reliability, ease of operation, and photovoltaic power generation efficiency.

[0006] Therefore, this invention proposes a self-draining rain-fighting photovoltaic module decontamination device to solve the above problems. Summary of the Invention

[0009] Preferably, the mounting strip and the splicing plate are arranged parallel to the photovoltaic panel, and the splicing body is attached to the mounting strip.

[0010] Preferably, the mounting groove is connected to the snap ring groove, and the sliding column is composed of two sets of columns with different diameters.

[0011] Preferably, the ball groove is provided in six sets at equal intervals around the mounting column tube, the upper end of the return spring is fixedly connected to the upper end of the sliding column, and the lower end is fixedly connected to the inner wall of the mounting column tube. The limiting ball is set on the outer ring of the conical body and fits against the outer inclined surface of the conical body. The limiting ball is provided in six sets around the central axis of the sliding column.

[0012] Preferably, the eccentric contact body and the rotating column are connected in an off-center state.

[0013] Preferably, the second component includes a current collector plate fixedly connected to the upper end of the splicing plate. The current collector plate is fixedly connected to two sets of splicing plates on both sides near the photovoltaic panel. A hemisphere is fixedly connected to the current collector plate. Multiple sets of current collectors are arranged alternately on the current collector plate. The end of the current collector plate near the photovoltaic panel has an inner groove, and a torsion spring column is rotatably connected in the inner groove of the current collector plate.

[0014] Preferably, a wave strip is fixedly connected to the torsion spring column, a torsion spring is built into the connection end between the torsion spring column and the wave strip, a miniature tension spring is fixedly connected to the bend of the wave strip, multiple sets of miniature tension springs are provided, and a flow plate is fixedly connected to the end of the wave strip away from the torsion spring column.

[0015] Preferably, the current collector is inclined and positioned at the upper end of the inclined direction of the photovoltaic panel. The splicing plate and the current collector are combined and spliced ​​in a semi-enclosed manner on the outer ring of the photovoltaic panel. Multiple sets of torsion spring columns and inner grooves are equally spaced.

[0016] Preferably, the corrugated strips are arranged side by side on the surface of the photovoltaic panel. The corrugated strips are made of transparent flexible polymer material and have flexible metal strips embedded inside them. The flow plate is rectangular and is attached to the photovoltaic panel.

[0017] Compared with the prior art, the present invention provides a self-draining photovoltaic module decontamination device for rainy days, which has the following beneficial effects: By collecting rainwater through a collector plate and guiding and turbulently flowing through a hemispherical structure, the rainwater is created into a turbulent flow with sufficient scouring force. The flow channel shape is then adaptively adjusted by corrugated strips according to the rainfall intensity, achieving comprehensive and efficient cleaning of the photovoltaic panel surface under varying rainfall levels. Dirt is naturally discharged along the drainage channels of the photovoltaic panel with the rainwater. This design differs from reliance on manual cleaning or electric / hydraulic power mechanisms, significantly reducing the labor costs and energy consumption for cleaning photovoltaic modules. It also avoids potential malfunctions during the operation of power mechanisms, improving the reliability of the device.

[0018] Thanks to the adaptive adjustment capability of the second component, the curvature of the corrugated strip can be flexibly adjusted according to the amount of rainfall: when the rainfall is light, the corrugated strip maintains a larger bend shape, reduces the channel spacing, increases the water flow rate and the concentration of rinsing, and ensures effective rinsing of stubborn stains on the photovoltaic panel surface; when the rainfall is heavy, the corrugated strip tends to be straight, expands the channel spacing, increases the water flow rate and cleaning coverage, and avoids incomplete cleaning of local areas. Meanwhile, the hemispherical shape effectively breaks up the continuous water film formed by rainwater on the surface of the collector plate and photovoltaic panel, mitigating the impact of rainwater, changing the direction of water flow to create turbulence, and preventing scaling caused by prolonged water stagnation, thus further improving the cleaning effect. In addition, the corrugated strips are made of transparent, flexible polymer material, which adheres to the surface of the photovoltaic panel without affecting its light transmittance, ensuring the photovoltaic module's performance. The power generation efficiency is not affected by the decontamination device.

[0019] Through the design of the first component, the mounting strip is set parallel to the photovoltaic panel, the splicing plate is attached to the surface of the photovoltaic panel, and the splicing body is tightly attached to the mounting strip, providing a precise positioning benchmark for the installation of the device; the plug-in cooperation between the mounting column tube and the mounting groove, combined with the synergistic effect of the limiting ball, cone, and eccentric contact, can form a stable limiting structure, effectively preventing the mounting column tube from disengaging from the mounting groove, realizing a stable connection between the first component, the photovoltaic panel, and the ground frame, and ensuring the structural stability of the device under the impact of rainwater flow and outdoor environment.

[0020] Meanwhile, the reset spring enables the sliding column, cone, and limit ball to be quickly reset. Operators can lock and unlock the device simply by turning the eccentric contact clockwise or counterclockwise. The disassembly and assembly are convenient, highly repeatable, and facilitate subsequent maintenance, repair, and replacement of the device. Attached Figure Description

[0023] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example Please refer to Figures 1 to 6 As shown: To address the problems mentioned in the technical solutions, this invention provides a self-draining rain-fighting photovoltaic module cleaning device, comprising: a floor frame 11 and a first component mounted thereon, wherein a photovoltaic panel 12 is obliquely mounted on the floor frame 11, and a drainage channel 13 is spaced apart on the photovoltaic panel 12; the first component comprises: mounting strips 21 fixedly mounted on both sides of the floor frame 11, and a splicing plate 22 is attached to the photovoltaic panel 12, with splicing bodies 23 fixedly connected to both sides of the splicing plate 22; The second component is fixedly connected to the photovoltaic panel 12 through the first component; The first component also includes: a mounting groove 24 formed on the upper surface of the mounting strip 21, a snap-fit ​​ring groove 25 formed at the lower end of the mounting groove 24, a mounting post tube 26 fixedly connected to the bottom of the assembled body 23, the mounting post tube 26 being inserted into the mounting groove 24, and the snap-fit ​​ring groove 25 being arranged around the outer ring of the ball groove 27 and the limiting ball 211, the bottom of the mounting post tube 26 having a ball groove 27, a sliding post 28 slidably connected inside the mounting post tube 26, a cone 29 fixedly connected to the bottom of the sliding post 28, a return spring 210 sleeved on the outer ring of the upper end of the sliding post 28, and a snap-fit ​​ring 29 being formed inside the ball groove 27. There is a limiting ball 211, and a spring is fixedly connected to the outer ring of the limiting ball 211. The other end of the spring is fixedly connected to the mounting column tube 26. This spring is used to release the compression of the limiting ball 211 after the cone body 29 moves upward, and then reset under the release of the spring force. A symmetrical arc body 212 is fixedly connected to the upper end of the assembled body 23. The symmetrical arc body 212 is composed of two sets of symmetrically arranged arc bodies. A through groove is opened on the symmetrical arc body 212. A rotating column 213 is fixedly connected in the through groove of the symmetrical arc body 212. An eccentric contact body 214 is rotatably connected to the outer ring of the middle part of the rotating column 213. The eccentric contact 214 is mainly used by the operator to deflect it clockwise after the mounting column tube 26 is inserted into the bottom of the mounting groove 24. The eccentric contact 214 causes its eccentric protruding side to press down against the sliding column 28. The sliding column 28 slides down, pushing the conical body 29 towards the bottom of the mounting column tube 26. This causes the inclined surface of the conical body 29 to squeeze the limiting ball 211 to move outward. The limiting ball 211 is engaged in the ball groove 27 and partially protrudes to the outside of the mounting column tube 26, cooperating with the engaging ring groove 25 to form a limit, preventing the mounting column tube 26 from disengaging from the mounting groove 24.

[0026] It also includes a second component for cleaning and decontaminating the photovoltaic panel 12.

[0027] The mounting strip 21 and the splicing plate 22 are both arranged parallel to the photovoltaic panel 12, and the splicing body 23 is fitted into the mounting strip 21. The mounting groove 24 is connected to the snap-fit ​​ring groove 25, and the sliding column 28 consists of two sets of columns with different diameters. The ball groove 27 is provided with six sets of equally spaced mounting columns 26, and the upper end of the return spring 210 is fixedly connected to the upper end of the sliding column 28. The lower end is fixedly connected to the inner wall of the mounting column tube 26, and the limiting ball 211 is set on the outer ring of the cone 29 and attached to the outer inclined surface of the cone 29. The limiting ball 211 is arranged in six sets around the central axis of the sliding column 28, and the eccentric contact body 214 is connected to the rotating column 213 in an off-center state.

[0028] A further embodiment: Please refer to Figures 7 to 9 As shown: The second component includes a collector plate 31 fixedly connected to the upper end of the splicing plate 22. The collector plate 31 is used to increase the contact surface of rainwater and collect water flow to increase the flushing volume. The two sides of the collector plate 31 near the photovoltaic panel 12 are fixedly connected to two sets of splicing plates 22 respectively. A hemispherical sphere 32 is fixedly connected to the collector plate 31. Multiple sets of hemispherical spheres 32 are arranged on the collector plate 31 in an alternating manner. The hemispherical spheres 32 are used to break the continuous water film, increase the rainwater dispersion flow rate, prevent the formation of water film on the plane of the collector plate 31, and reduce the impact force of rainwater. The alternating arrangement of the hemispherical spheres 32 is used to change the direction of water flow, form turbulence, and prevent scale buildup. The end of the collector plate 31 near the photovoltaic panel 12 has an inner groove. A torsion spring column 33 is rotatably connected in the inner groove on the collector plate 31.

[0029] The torsion spring column 33 can be adjusted to different bending angles according to actual needs. Under the action of rainwater, the bending degree of the corrugated strip 34 adaptively adjusts with the amount of rainfall: the less rainfall, the weaker the impact force of the water flow, and the corrugated strip 34 maintains a larger bending shape under the action of the micro tension spring 35, reducing the channel spacing to increase the water flow velocity and scouring concentration; the more rainfall, the stronger the impact force of the water flow on the flow plate 36, and the flow plate 36 pulls the corrugated strip 34 to overcome the elasticity of the micro tension spring 35, making the corrugated strip 34 tend to be straight, and expanding the channel spacing to increase the water flow rate and cleaning coverage; after the rain stops, the micro tension spring 35 drives the corrugated strip to reset, restoring its initial shape. Initial flow channel morphology.

[0030] A wave strip 34 is fixedly connected to the torsion spring column 33. A torsion spring is built into the connection end between the torsion spring column 33 and the wave strip 34. A miniature tension spring 35 is fixedly connected to the bend of the wave strip 34. Multiple sets of miniature tension springs 35 are provided. The number of miniature tension springs 35 can be adjusted according to the actual bend of the wave strip 34. A flow plate 36 is fixedly connected to the end of the wave strip 34 away from the torsion spring column 33.

[0031] The current collector 31 is inclined and is located at the upper end of the inclined direction of the photovoltaic panel 12. The splicing plate 22 and the current collector 31 are combined and spliced ​​in a semi-enclosed manner on the outer ring of the photovoltaic panel 12. Multiple sets of torsion spring columns 33 and inner grooves are equally spaced.

[0032] Corrugated strips 34 are arranged side-by-side on the surface of the photovoltaic panel 12. The corrugated strips 34 are made of transparent and flexible polymer material, which can be implemented as flexible PC. The corrugated strips 34 rotate around the torsion spring column 33 as the fulcrum. Their main body is placed in close contact with the surface of the photovoltaic panel 12 without affecting the light transmittance. Flexible metal strips are embedded inside them. Under the impact of rainwater, the corrugated strips 34 swing and are connected to the photovoltaic panel. On surface 12, the flow plate 36 is cleaned by friction with the photovoltaic panel 12. The flow plate 36 is rectangular and is positioned relative to the photovoltaic panel. 12. Fitting connection.

[0033] The working principle of all the content in the above embodiments is as follows: The mounting strip 21 of the first component is fixedly installed on both sides of the floor frame 11, ensuring that the mounting strip 21 is parallel to the photovoltaic panel 12. Then, the splicing plate 22 is attached to the surface of the photovoltaic panel 12, so that the splicing body 23 fixedly connected on both sides of the splicing plate 22 is tightly attached to the mounting strip 21, realizing the initial attachment and positioning of the first component and the photovoltaic panel 12, providing a precise positioning reference for the subsequent assembly of the locking structure.

[0034] After the initial fitting and positioning are completed, align the mounting post tube 26 fixedly connected to the bottom of the assembly 23 with the mounting groove 24 opened on the upper surface of the mounting strip 21, and slowly insert the mounting post tube 26 into the mounting groove 24 until the mounting post tube 26 reaches the bottom of the mounting groove 24; at this time, the snap ring groove 25 connected at the lower end of the mounting groove 24 just surrounds the ball groove 27 and the outer ring of the limiting ball 211 at the bottom of the mounting post tube 26, providing structural support for subsequent limiting and fixing.

[0035] The operator rotates the eccentric contact 214, which is rotatably connected within the symmetrical arc 212, clockwise. This causes the eccentric protruding side of the eccentric contact 214 to press downward against the sliding column 28, which is slidably connected within the mounting column tube 26. Under this pressure, the sliding column 28 slides downward, simultaneously moving the cone 29, which is fixedly connected to its bottom, towards the bottom of the mounting column tube 26. The inclined surface of the cone 29 engages with the six sets of limiting balls 211 arranged around the central axis of the sliding column 28. As the cone 29 moves downward, its inclined surface compresses the six sets of limiting balls. 211 moves outward, causing the limiting ball 211 to engage with the six sets of ball grooves 27 that are opened around the bottom of the mounting column tube 26. The limiting ball 211 partially protrudes outside the mounting column tube 26, and cooperates with the engaging ring groove 25 to form a stable limiting structure, effectively preventing the mounting column tube 26 from disengaging from the mounting groove 24, thereby achieving a stable connection between the first component and the photovoltaic panel 12 and the mounting frame 11.

[0036] The upper end of the return spring 210, which is sleeved on the outer ring of the upper end of the slide column 28, is fixedly connected to the upper end of the slide column 28 and the lower end is fixedly connected to the inner wall of the mounting column tube 26. When the eccentric contact 214 is reset, it drives the slide column 28 and the cone 29 back to the initial position. The limiting ball 211 disengages from the snap ring groove 25 under its own weight and the gap after the cone 29 is reset, ensuring the repeatability of the installation structure and providing reliable support for the stable operation of the second component.

[0037] The second component is fixedly connected to the photovoltaic panel 12 through the first component. Its collector plate 31 is fixedly connected to the upper end of the splicing plate 22, and is set at an angle and located at the upper end of the photovoltaic panel 12 in the direction of the angle. The splicing plate 22 and the collector plate 31 are combined and spliced ​​into a semi-enclosed structure and fitted on the outer ring of the photovoltaic panel 12. The two sides of the collector plate 31 near the photovoltaic panel 12 are fixedly connected to the two sets of splicing plates 22 respectively, which can effectively increase the rainwater contact surface, collect the rainwater falling in the rain, and increase the water flow flushing volume.

[0038] Multiple sets of staggered hemispherical bodies 32 are fixedly connected to the collector plate 31. When rainwater falls onto the surface of the collector plate 31, the hemispherical bodies 32 can effectively break the continuous water film formed on the surface of the collector plate 31, improve the dispersion rate of rainwater, and at the same time reduce the impact force when the rainwater falls. In addition, the staggered arrangement of the hemispherical bodies 32 can change the direction of water flow, so that the water flow forms turbulence, and prevent the water flow from staying on the surface of the collector plate 31 and the photovoltaic panel 12 for a long time and forming scale.

[0039] The current collector 31 has an inner groove at one end near the photovoltaic panel 12. Multiple sets of torsion spring columns 33 are rotatably connected in the inner groove. The torsion spring columns 33 can be adjusted to different bending angles according to actual needs. The corrugated strips 34 fixedly connected to the torsion spring columns 33 are arranged side by side on the surface of the photovoltaic panel 12. The connection end between the torsion spring column 33 and the corrugated strip 34 has a built-in torsion spring. The corrugated strip 34 is made of transparent flexible polymer material. The corrugated strip 34 is attached to the surface of the photovoltaic panel 12 without affecting the light transmittance of the photovoltaic panel 12. A flexible metal strip is embedded inside to ensure structural stability. A rectangular flow plate 36 is fixedly connected to the end of the corrugated strip 34 away from the torsion spring column 33. The flow plate 36 is attached to the photovoltaic panel 12. Multiple sets of micro tension springs 35 are fixedly connected at the bend of the corrugated strip 34. The number of micro tension springs 35 can be adjusted according to the degree of bending of the corrugated strip 34.

[0040] During rainy weather, rainwater is collected and guided by the collector plate 31 and flows to the surface of the photovoltaic panel 12. At the same time, the force of the water flow acts on the condenser plate 12. Plate 36 provides thrust to the flow plate 36, causing it to move downwards along the inclined surface of the photovoltaic panel 12. Under this force, the corrugated strip 34 undergoes tensile deformation. The degree of bending of the corrugated strip 34 is adaptively adjusted according to the amount of rainfall, providing different impact forces to the flow plate 36: When the rainfall is light, the water flow impact is weak, and the corrugated strip 34 maintains a larger bending shape under the elastic force of the micro-tension spring 35. The larger bending of the corrugated strip 34 reduces the channel spacing between the corrugated strips, thereby increasing the water flow velocity and scouring concentration, enhancing the scouring effect on the surface of the photovoltaic panel 12. The dirt is discharged along the guide channel 13 with the rainwater; when the rainfall is heavy, the water flow impacts the flow plate 36. With the increased force, the flow plate 36 pulls the corrugated strip 34 to overcome the elasticity of the micro tension spring 35, making the corrugated strip 34 tend to be straight and the flow channel spacing between adjacent corrugated strips 34 is expanded, thereby increasing the water flow rate and cleaning coverage. At the same time, with the cooperation of the corrugated strip 34 and the torsion spring column 33, the rainwater impact stretches the corrugated strip 34 and swings and deflects it around the torsion spring column 33 as the axis. Meanwhile, the torsion spring inside the torsion spring column 33 resets the corrugated strip 34 when the impact force of external rainwater decreases. After the rainwater softens the impurities on the photovoltaic panel 12, the swing of the corrugated strip 34 cleans the photovoltaic panel 12, ensuring that all areas of the photovoltaic panel 12 surface can be effectively rinsed, and further removing the stains attached to the surface. Therefore, the torsion spring column 33 is used to assist the swing and reset of the wave strip 34, and the flow plate 36 and the miniature spring 35 work together to assist the change of the bending degree of the wave strip, thereby indirectly adjusting the impact force of rainwater, and they work together to implement the operation.

[0041] After the rain stops, the impact of the water flow on the flow plate 36 disappears, the miniature tension spring 35 recovers its elastic deformation, and drives the wave strip. 34. Reset, returning to the initial bent flow channel shape; at the same time, if the device needs to be disassembled or repaired, the operator deflects the eccentric contact 214 counterclockwise, the pressure of the eccentric contact 214 on the sliding column 28 disappears, the reset spring 210 drives the sliding column 28 and the cone 29 to reset upward, the squeezing force of the cone 29 on the limiting ball 211 is released, the limiting ball 211 disengages from the snap ring groove 25 and retracts into the ball groove 27, at this time the mounting column tube 26 can be pulled out from the mounting groove 24 to complete the unlocking of the first component, which is convenient for subsequent maintenance and repair of the device.

[0042] The entire working process requires no additional power drive, relying entirely on the self-draining effect of rainwater and the adaptive adjustment of each component to achieve automatic cleaning of the photovoltaic panel 12 surface, ensuring the light transmission efficiency of the photovoltaic panel 12, reducing manual cleaning costs, and the structure is easy to operate and highly repeatable.
