Description

Technical Field

[0001] This invention relates to the field of distributed photovoltaic power station technology, specifically to a proactively cleaned distributed photovoltaic power station. Background Technology

[0002] Photovoltaic power generation is a technology that uses solar photovoltaic cells to directly convert solar radiation energy into electrical energy. A photovoltaic cell is a semiconductor device with light-to-electricity conversion characteristics, directly converting solar radiation energy into direct current (DC). Under sunlight, free charges can be generated within a semiconductor with special electrical properties. These free charges move directionally and accumulate, creating an electromotive force (EMF) at its terminals. When the terminals are closed with a conductor, a current is generated. A distributed photovoltaic power station system mainly consists of photovoltaic modules, inverters, grid-connected equipment, and a monitoring system. The photovoltaic modules are responsible for converting solar energy into DC; the inverter converts DC into AC for user use or grid connection; the grid-connected equipment connects the distributed photovoltaic system to the grid; and the monitoring system monitors and controls the operating status of the photovoltaic power generation system in real time, improving system efficiency and stability. Distributed photovoltaic power stations utilize decentralized resources to directly convert solar energy into electrical energy, advocating for local power generation, grid connection, conversion, and use.

[0003] Since photovoltaic power stations are usually installed outdoors, pollutants such as dust and sand in the air will form a "shading layer" on the surface of the photovoltaic panels, making it difficult for the photovoltaic panels to receive sufficient sunlight. When cleaning the surface of the photovoltaic panels, although a fine brush can remove the dust, the dust is easily dispersed in the air during the cleaning process. The dispersed dust may fall back onto the surface of the photovoltaic panels, causing secondary pollution. On the other hand, a fine brush is not convenient to remove stubborn pollutants on the surface of the photovoltaic panels. Stubborn pollutants can easily form local shadows on the surface of the panels. The shaded photovoltaic cells not only affect the power generation effect, but may also become a load and cause hot spots, damaging the photovoltaic panels.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide an active cleaning distributed photovoltaic power station to solve the problems in the background technology where dust easily disperses in the air when cleaning the surface of photovoltaic panels, and the dispersed dust may fall back onto the photovoltaic panel surface, causing secondary pollution.

The output end of the motor extends through the moving platform into the sliding groove and is connected to the lead screw. The slider has a thread inside and is threaded to the lead screw. Six sets of photovoltaic panels are installed on the surface of the distribution platform. The six sets of photovoltaic panels are arranged in a row on the surface of the distribution platform, and a slot is opened in the center of the distribution platform in the gap between the two rows of photovoltaic panels.

[0008] Preferably, the slide is designed as an L-shaped rod, and a spring is installed inside the connecting frame. One end of the spring is connected to the side of the slide near the inner wall of the connecting frame, and the other end of the spring is connected to the inner wall of the connecting frame. The bottom of the slide slides vertically and is limited to sliding on the surface of the slide rod. A spring is sleeved on the slide rod, one end of the spring is connected to the top protrusion of the slide rod, and the other end of the spring is connected to the top of the bottom of the slide.

[0009] Preferably, a groove is provided at the top center of the cleaning table, and the bottom protrusion of the connecting table slides within the groove at the top center of the cleaning table; a spring is provided in the groove at the top center of the cleaning table, one end of the spring is connected to the side end of the bottom protrusion of the connecting table, and the other end of the spring is connected to the side wall of the groove at the top of the cleaning table.

[0010] Preferably, a ball bearing is installed at the bottom of the top plate, and the ball bearing abuts against the top of the cleaning table. The top of the pressure table has an inclined surface, and the pressure rod abuts against the inclined surface of the pressure table.

[0011] Preferably, the spray adjustment mechanism includes a top rod that is vertically limited and slidably connected to the inside of the top of the spray table. Both sides of the top rod are equipped with abutment plates. A shielding platform is installed at the bottom of the top rod inside the spray table. The end of the pressure rod near the electric push rod is connected to one end of the abutment rod. The other end of the abutment rod abuts against the surface of the abutment plate. A shielding block is horizontally limited and slidably connected inside the water injection platform.

[0012] Preferably, the water injection platform has a square notch on the side near the electric push rod, the blocking block is connected to one end of the auxiliary rod on the side near the square notch, and the auxiliary rod slides within the square notch, and the other end of the auxiliary rod is connected to the abutment rod.

[0013] Preferably, a slope is provided in the lower area of ​​the inner wall of the shielding platform and a slope is provided in the lower area of ​​the outer wall of the spraying platform, and the inclination angle of the slope in the lower area of ​​the inner wall of the spraying platform is greater than the inclination angle of the slope in the lower area of ​​the outer wall of the spraying platform.

[0014] Preferably, the contact plate is inclined, and a spring is sleeved on the surface of the top rod. One end of the spring is connected to the top protrusion of the top rod, and the other end of the spring is connected to the spray table.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the installation of a spray station and a cleaning station, can clean the surface of photovoltaic panels, preventing dust from adhering to the surface for a long time and reacting with moisture and chemicals in the air to form dirt or corrosive substances, thus damaging the surface material of the photovoltaic panels. Furthermore, water can moisten the surface of dust particles, making them easier to stick together. Originally dispersed dust particles will gather together to form larger particle clusters after being moistened, thereby preventing dust from being dispersed into the air again and causing secondary pollution to the photovoltaic panels.

[0016] This invention, through its cleaning pressurization component, connecting plate, and cleaning platform, enhances the cleaning effect of the photovoltaic panel by increasing the pressure applied to the panel based on the real-time resistance when the dirt on the panel surface is highly viscous. The cleaning pressurization component intelligently adjusts the pressure based on real-time resistance, ensuring full contact between the cleaning platform and the photovoltaic panel surface, increasing friction, and thus more effectively removing stubborn dirt. When the dirt viscosity is low, a smaller pressure is used for cleaning, reducing damage to the photovoltaic panel surface; the pressure is only increased when the dirt viscosity is high and a stronger cleaning force is required, ensuring cleaning effectiveness while maximizing the protection of the photovoltaic panel.

[0017] This invention, by setting up a spray adjustment mechanism and a spray platform, can reduce the output diameter of the spray platform and increase the injection diameter of the water injection platform when the viscosity of the dirt on the photovoltaic panel surface is high. Based on the real-time resistance experienced by the cleaning platform, the pressure of the spray platform is increased. When the viscosity of the dirt on the photovoltaic panel surface is high, conventional spraying methods may be insufficient to effectively remove the dirt. By reducing the output diameter of the spray platform, increasing the injection diameter, and increasing the spray pressure, the speed of the sprayed water can be significantly increased. The high-speed water flow has a stronger impact force, which can directly act on stubborn dirt and peel it off the photovoltaic panel surface. In areas with lower dirt viscosity, the spray pressure can be appropriately reduced, while in areas with higher dirt viscosity, the pressure is increased for focused cleaning.

[0020] 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.

[0021] Please see Figures 1-14 This invention provides a technical solution: an actively cleaned distributed photovoltaic power station, comprising a mounting frame 1 and distribution platforms 2. Multiple distribution platforms 2 are mounted on the top of the mounting frame 1. Movable platforms 3 are mounted on the sides of the distribution platforms 2. Motors are mounted on the outer ends of the movable platforms 3. A lead screw 4 is rotatably connected within a sliding groove inside the movable platform 3. The motor output extends through the movable platform 3 into the sliding groove and is connected to the lead screw 4. A slider 5 has internal threads and is threadedly connected to the lead screw 4. Six sets of photovoltaic panels 14 are mounted on the surface of the distribution platforms 2. The distribution platform 2 is arranged in an array on its surface. A groove is opened in the center of the distribution platform 2 in the gap between the two rows of photovoltaic panels 14. A slider 5 is slidably connected in the sliding groove inside the moving platform 3. A connecting plate 6 is installed at the top of the slider 5. A spray table 7 is installed on the side of the connecting plate 6. An electric push rod 8 is installed in the center of the connecting plate 6. A cleaning table 9 is set at the protruding end of the electric push rod 8. A connecting frame 10 is installed on the top of the connecting plate 6. A cleaning pressurization component is set in the gap between the connecting plate 6 and the cleaning table 9. A water injection platform 12 is installed on the top of the spray table 7.

[0022] The water injection platform 12 is connected to an external water pipe. Then, the controller drives the internal lead screw 4 of the moving platform 3 to rotate clockwise via a motor. The rotation of the lead screw 4 inside the moving platform 3 causes the slider 5 to slide in the internal groove of the moving platform 3. While the slider 5 slides inside the moving platform 3, it also causes the connecting plate 6 to slide smoothly along the surface of the distribution platform 2. At the same time, while the controller drives the motor to rotate the lead screw 4 clockwise, it synchronously drives the extended end of the electric push rod 8 to push the connecting platform 114, so that the cleaning platform 9 moves precisely towards the distribution platform 2 until the cleaning platform 9 and the surface of the photovoltaic panel 14 form a uniform and close contact state. At this time, external water is continuously supplied to the spray station 7 through the water injection platform 12. During the process of the cleaning station 9 moving and wiping the dirt on the surface of the photovoltaic panel 14 with the connecting plate 6, the spray station 7 simultaneously outputs water flow to the cleaning area. This coordinated action not only reduces the wiping resistance by pre-wetting the dirt with water flow, significantly improving the cleaning efficiency of the cleaning station 9, but also solves the problem of secondary pollution in traditional cleaning from the root: the water flow can fully wet the surface of dust particles, and use the surface tension of water molecules to make the originally dispersed fine dust adsorb and stick together to form larger particle clusters. These particle clusters are removed from the surface of the photovoltaic panel 14 by the water flow under the wiping action of the cleaning station 9. This not only avoids the dry dust from being scattered due to airflow disturbance during the wiping process, but also prevents the dispersed dust from settling back into the cleaned area and causing secondary pollution, thus extending the duration of the single cleaning effect. After cleaning the photovoltaic panel 14 on the surface of the distribution station 2, the wastewater after cleaning is discharged through the drain on the surface of the distribution station 2. In addition, the continuous rinsing of water can promptly remove the dirt and debris generated by wiping the cleaning table 9, preventing the dirt from accumulating on the surface of the cleaning table 9 and causing secondary scratches to the photovoltaic panel 14. At the same time, it reduces the wear and tear on the cleaning table 9, effectively reducing equipment operation and maintenance costs while ensuring the light transmittance of the photovoltaic panel 14 surface.

[0023] In one embodiment of the present invention, the cleaning pressurization assembly includes a slide 111 that is slidably mounted inside a connecting frame 10. A pressure rod 112 is mounted on the side of the slide 111 near the electric push rod 8. A slide rod 113 is mounted on the top of the cleaning platform 9. The slide 111 is designed as an L-shaped rod. A spring is provided inside the connecting frame 10. One end of the spring is connected to the side of the slide 111 near the inner wall of the connecting frame 10, and the other end of the spring is connected to the inner wall of the connecting frame 10. The bottom of the slide 111 slides vertically on the surface of the slide rod 113. A spring is sleeved on the surface of the slide rod 113. One end of the spring is connected to a protrusion at the top of the slide rod 113, and the other end of the spring is connected to the top of the bottom of the slide 111. A connecting platform 114 is mounted on the extended end of the electric push rod 8. A thin rod 115 is slidably connected to the inside of the connecting platform 114 near its edge. A pressure plate 116 is installed at the top of the thin rod 115 and is vertically slidably connected to the inside of the connecting plate 6. A top plate 117 is installed at the bottom of the thin rod 115, and a ball bearing is installed at the bottom of the top plate 117, with the ball bearing abutting against the top of the cleaning table 9. The top of the pressure plate 116 has an inclined surface, and the pressure rod 112 abuts against the inclined surface of the pressure plate 116. A groove is provided at the top center of the cleaning table 9, and the bottom protrusion of the connecting platform 114 slides within the groove at the top center of the cleaning table 9. A spring is installed in the groove at the top center of the cleaning table 9, with one end of the spring connected to the side end of the bottom protrusion of the connecting platform 114 and the other end of the spring connected to the side wall of the groove at the top of the cleaning table 9. When the dirt adhering to the surface of the photovoltaic panel 14 is highly adhesive, the cleaning platform 9 will experience significant resistance during wiping due to the stickiness of the dirt. This force will push the cleaning platform 9 to move in the opposite direction, causing the slide 111 to slide within the connecting frame 10. Simultaneously, the bottom of the connecting platform 114 at the extended end of the electric push rod 8 slides within the top groove of the cleaning platform 9, preventing the cleaning platform 9 from jamming during reverse displacement. This effectively ensures the smooth operation of the mechanical structure and reduces component wear caused by jamming. As the slide 111 slides, it drives the pressure rod 112 to move together. When the pressure rod 112 moves, it presses against the inclined surface of the pressure table 116. The pressure table 116, under the pressure of the pressure rod 112, moves the top plate 117 downward through the thin rod 115, causing the cleaning platform 9 to move towards the photovoltaic panel 14. When the ball bearings at the bottom of the top plate 117 contact the top of the cleaning platform 9, they can convert sliding friction into rolling friction, significantly reducing the friction generated during the reverse displacement of the cleaning platform 9. This reduces energy loss and avoids component heating and wear caused by friction. The sliding rod 113 at the top of the cleaning platform 9 slides within the lower area of ​​the carriage 111. When the connecting plate 6 moves the cleaning platform 9, it automatically increases the cleaning force of the cleaning platform 9 on the photovoltaic panel 14 according to the resistance, ensuring sufficient friction to thoroughly remove sticky dirt. This dynamic pressure adjustment mechanism brings multiple advantages: After the dirt is cleaned, the cleaning platform 9 loses the resistance applied by the photovoltaic panel 14, and the springs inside the connecting frame 10 and the sliding rod 113 rebound, causing the carriage 111 to return to its original position, so that the cleaning platform 9 is accurately reset to the initial position, ready for the next cleaning; the cleaning pressurization component can intelligently adjust the holding force according to the real-time resistance. When the dirt viscosity is low, it automatically uses a smaller holding force for cleaning, which can meet the daily dust removal needs and reduce the frictional wear between the cleaning platform 9 and the surface of the photovoltaic panel 14; only when the dirt viscosity is high and a greater force is required for cleaning will the holding force be automatically increased, ensuring an improved removal rate of stubborn stains, truly realizing intelligent cleaning with "force applied on demand". This adaptive adjustment mode ensures cleaning effectiveness while maximizing the protection of the tempered glass and anti-reflective film on the surface of the photovoltaic panel 14, extending the service life of the photovoltaic module, and reducing the operation and maintenance costs of the cleaning equipment.

[0024] In one embodiment of the present invention, the spray adjustment mechanism includes a top rod 131 vertically limited and slidably connected to the inside of the top of the spray table 7. Abutment plates 133 are installed on both sides of the top rod 131, and the abutment plates 133 are inclined. A spring is sleeved on the surface of the top rod 131, with one end of the spring connected to a protrusion at the top of the top rod 131 and the other end connected to the spray table 7. The other end of an abutment rod 134 abuts against the surface of the abutment plate 133. A shielding platform 132 is installed at the bottom of the top rod 131 inside the spray table 7, and an inclined surface is formed in the lower area of ​​the inner wall of the shielding platform 132. A slope is provided in the lower area of ​​the outer wall of the spray table 7. The inclination angle of the slope in the lower area of ​​the inner wall of the spray table 7 is greater than that of the slope in the lower area of ​​the outer wall of the spray table 7. An abutment rod 134 is installed at one end of the pressure rod 112 near the electric push rod 8. A blocking block 136 is laterally limited and slidably connected inside the water injection platform 12. A square notch is provided on the side of the water injection platform 12 near the electric push rod 8. An auxiliary rod 135 is installed on the side of the blocking block 136 near the square notch, and the auxiliary rod 135 slides within the square notch. The other end of the auxiliary rod 135 is connected to the abutment rod 134. As the slide 111 moves the pressure rod 112 to press the inclined surface of the pressure table 116, the pressure rod 112 simultaneously moves the contact rod 134. When the contact rod 134 moves, it presses the inclined surface of the contact plate 133, pushing the shielding platform 132 down inside the spray table 7, so that the output diameter of the spray table 7 is precisely reduced. At the same time, during the movement, the contact rod 134 pulls the shielding block 136 to move inside the water injection platform 12 through the auxiliary rod 135, so that the inner diameter of the water injection platform 12 gradually increases. This linkage mechanism can realize the dynamic adjustment of the spray pressure, so that the impact force of the water source output by the spray table 7 increases synchronously with the viscosity of the dirt, forming a synergistic cleaning effect of "mechanical wiping + high-pressure water flow impact". When the dirt on the surface of the photovoltaic panel 14 is highly viscous, conventional spray pressure is insufficient to penetrate and loosen it. However, by reducing the spray nozzle diameter and increasing the injection nozzle diameter, the water flow velocity can be increased. The high-speed water flow can directly impact the crevices of stubborn dirt, using hydraulic shear force to pre-peel it from the surface of the photovoltaic panel 14. This reduces the mechanical wiping resistance of the cleaning platform 9, significantly improving the removal efficiency of stubborn stains. More importantly, this adjustment mechanism is regionally targeted: in areas with lower dirt viscosity, the system automatically restores the conventional spray pressure, avoiding excessive impact of high-pressure water flow on the anti-reflective film on the surface of the photovoltaic panel 14; while in localized areas with higher dirt viscosity, a high-pressure mode is automatically triggered, achieving "precise and intensive cleaning of key areas." This on-demand spray strategy ensures thorough removal of stubborn dirt while avoiding waste of energy and water resources. At the same time, the pre-peeling effect of the water flow reduces the friction intensity between the cleaning platform 9 and the photovoltaic panel 14, extending the service life of the cleaning cotton. Ultimately, while improving cleaning effectiveness, it achieves a dual reduction in equipment wear and maintenance costs.

[0025] Working principle: During cleaning, the water injection platform 12 is first connected to the external water pipe. Then, the controller drives the internal lead screw 4 of the moving platform 3 to rotate clockwise through the motor. The rotation of the lead screw 4 inside the moving platform 3 causes the slider 5 to slide in the sliding groove inside the moving platform 3. While the slider 5 is sliding inside the moving platform 3, it can also drive the connecting plate 6 to slide on the surface of the distribution platform 2. At the same time, while the controller drives the motor to rotate the lead screw 4 clockwise, the controller drives the electric push rod 8 to push the connecting platform 114 to move the cleaning platform 9 towards the distribution platform 2 until it contacts the surface of the photovoltaic panel 14. At this time, the external water source enters the spraying platform 7 through the water injection platform 12. While the connecting plate 6 drives the cleaning platform 9 to move and wipe the dirt on the surface of the photovoltaic panel 14, the spraying platform 7 continuously outputs water to increase the cleaning effect of the cleaning platform 9. After cleaning the photovoltaic panel 14 on the surface of the distribution platform 2, the cleaned wastewater is discharged through the drain on the surface of the distribution platform 2. When the dirt adhering to the surface of the photovoltaic panel 14 is highly adhesive, the cleaning table 9 will experience significant resistance during wiping due to the stickiness of the dirt. This force will push the cleaning table 9 to move in the opposite direction, causing the slide 111 to slide within the connecting frame 10. Simultaneously, the bottom of the connecting platform 114 at the extended end of the electric push rod 8 slides within the top groove of the cleaning table 9, preventing the cleaning table 9 from jamming during reverse movement. As the slide 111 slides, it also moves the pressure rod 112. When the pressure rod 112 moves, it presses against the inclined surface of the pressure table 116, causing the pressure table 116 to be squeezed by the pressure rod 112. The thin rod 115 drives the top plate 117 to move downward, causing the cleaning platform 9 to move toward the photovoltaic panel 14. When the bottom ball of the top plate 117 abuts against the top of the cleaning platform 9, it can avoid the friction generated when the cleaning platform 9 moves in the opposite direction. The slide rod 113 at the top of the cleaning platform 9 slides in a limited position in the lower area of ​​the slide 111. At this time, when the connecting plate 6 drives the cleaning platform 9 to move, it will increase the cleaning force of the cleaning platform 9 on the photovoltaic panel 14. After the dirt is cleaned, the cleaning platform 9 loses the resistance applied by the photovoltaic panel 14, and the springs inside the connecting frame 10 and the slide rod 113 rebound and drive the slide 111 back to its original position, so that the cleaning platform 9 moves to the initial position. As the slide 111 moves the pressure rod 112 to press the inclined surface of the pressure table 116, the pressure rod 112 also moves the contact rod 134. When the contact rod 134 moves, it presses the inclined surface of the contact plate 133, causing it to push the shielding platform 132 down inside the spray table 7. This reduces the output diameter of the spray table 7. At the same time, the contact rod 134 moves the shielding block 136 inside the water injection platform 12 through the auxiliary rod 135, causing the inner diameter of the water injection platform 12 to gradually increase. This gradually increases the pressure of the water source output by the spray table 7, which can impact the more viscous dirt and increase the cleaning effect of the cleaning table 9 on the photovoltaic panel 14.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
