Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic cleaning equipment, and in particular to equipment for cleaning photovoltaic panels. Background Art

[0002] Photovoltaic panels are devices that convert solar energy into electrical energy. They are mainly composed of multiple solar cell modules assembled on a panel in a certain way. Due to climate conditions and increased pollution, dust will be deposited on the photovoltaic panels every once in a while. The deposition of dust will block solar radiation, resulting in a reduction in the effective area irradiated on the photovoltaic panel, a decrease in the transmittance of the glass, and a weakening of the intensity of solar radiation received by the panel. This directly leads to a decrease in power generation and output power. When wet acidic or alkaline dust is attached to the surface of the glass cover, the components of the glass cover can react with the acid or alkali. As the glass is in an acidic or alkaline environment for a longer time, the surface of the glass will slowly be eroded, forming pits on the surface. This not only destroys the uniformity of light propagation in the glass, but also further reduces the power generation of the photovoltaic module.

[0003] However, the current cleaning method of photovoltaic panels is mostly to rinse them manually, which often takes a lot of time. When it is used to clean a certain amount of panels, the efficiency is low and the cleaning effect is poor. During the cleaning process, a large amount of foam will be generated on the surface of the photovoltaic panels due to the use of detergents. These foams are difficult to ensure that they are rinsed and removed thoroughly during the cleaning process. These residual foams will scatter and reflect light, causing the light to not pass evenly or be reflected by the surface, thereby causing light to be blocked. This blocking effect will affect the power generation efficiency of the photovoltaic power generation unit. In addition, the foam residue may change the physical properties of the surface, making it easier to absorb dust and other pollutants. This is because the surfactant in the foam may reduce the surface tension of water, making it easier for dust particles to adhere to the surface. Over time, these dust particles may accumulate on the surface of the photovoltaic power generation unit and form a dirt layer that is more difficult to remove; therefore, we propose a photovoltaic panel cleaning device to solve this problem.

[0012] The beneficial effects of the present invention are: In the present invention, the photovoltaic panel cleaning device is configured to move the fixing frame so that the mounting frame is located directly above the photovoltaic panel to be cleaned, and the mounting frame is driven to rotate by starting the electric push rod so that the mounting frame is parallel to the photovoltaic panel, and the driving shaft is driven to rotate by starting the stepping motor, and the driving shaft drives the driving gear to rotate, and the driving gear drives the moving seat to move along the mounting frame by meshing with the rack, so that the cleaning brush and the wiping plate abut against the surface of the photovoltaic panel; In the present invention, the photovoltaic panel cleaning device described in the present invention connects the tap water pipe with the water inlet of the water pump, and starts the water pump, the driving motor and the rotating motor. The water pump guides the tap water into the horizontal pipe, and then guides the tap water into the first water outlet cylinder, the second water outlet cylinder and the third water outlet cylinder through the horizontal pipe, and adds a cleaning agent in the first feeding hopper and a defoaming agent in the second feeding hopper, so that the tap water mixed with the cleaning agent is sprayed out through the nozzle at the bottom of the first water outlet cylinder, and cooperates with the rotating motor to drive the connecting shaft and the cleaning brush to rotate, so as to realize the scrubbing of the surface of the photovoltaic panel. At the same time, the tap water mixed with the defoaming agent is sprayed out through the nozzle at the bottom of the second water outlet cylinder, and the foam generated by the scrubbing is partially eliminated, and the tap water is sprayed out through the nozzle at the bottom of the third water outlet cylinder to further rinse the photovoltaic panel. At the same time, the driving motor drives the rotating shaft to rotate clockwise, and drives the connecting column to perform clockwise circular motion through the rotating arm, and the connecting column The square plate and the connecting plate are driven to perform clockwise circular motion by cooperating with the vertical plate, and under the guidance of the lifting plate, the vertical rod and the U-shaped rod, the square plate does not deflect while performing circular motion, and the square plate drives the fixed frame to perform clockwise circular motion, so that the fixed frame moves downward and moves to the left at the same time, moves upward and moves to the left at the same time, moves upward and moves to the right at the same time, that is, the fixed frame first moves downward to squeeze the wiping plate during the leftward movement, and then moves upward. During this process, the wiping plate is always in contact with the photovoltaic power generation panel, and the pressing force of the wiping plate first increases and then decreases, thereby realizing the wiping of the photovoltaic power generation panel by the wiping plate to facilitate wiping of the foam on the surface thereof, and the fixed frame first moves upward to disengage the wiping plate from the photovoltaic power generation panel during the rightward movement, and then moves downward to contact the photovoltaic power generation panel again, and so on and so forth, thereby realizing the one-way wiping of the photovoltaic power generation panel; In the present invention, the photovoltaic panel cleaning device described above uses a scrubbing component to scrub the surface of the photovoltaic panel. Due to the presence of detergent foam on the surface of the photovoltaic panel, the scrubbing plate and the photovoltaic panel slip. As the scrubbing plate wipes away the foam and the foam is washed away by the clean water sprayed from the third water outlet, the friction component between the scrubbing plate and the photovoltaic panel gradually increases, and the fixed frame is blocked while moving to the left, so that the square plate moves to the left relative to the fixed frame and squeezes the reset spring. When the resistance is large enough, the square plate contacts the touch button, thereby controlling the stepping motor to work for a period of time and shut down, that is, driving the moving seat and the mounting frame to move down along the mounting frame for a distance and then stop, thereby realizing cleaning of another area of ​​the photovoltaic panel. When the lower trapezoidal plate moves downward, the toothed plate will not be driven downward, and the toothed plate will push the lower trapezoidal plate to move leftward through the beveled teeth. The servo motor drives the moving seat and the mounting frame to move a certain distance. When the mounting frame moves, the abutting wheel abuts against the arc-shaped protrusion of the wave plate and pushes the bracket to move downward, thereby driving the upper trapezoidal plate to move to the left through the transverse plate and the arc-shaped connecting plate. At the same time, the cylinder drives the lower trapezoidal plate to move to the left through the push rod, so that the upper trapezoidal plate and the lower trapezoidal plate are both released from the fixation of the tooth plate, and the moving plate is reset under the action of the compression spring. In the present invention, the photovoltaic panel cleaning equipment can realize automatic flushing, brushing and scrubbing of the photovoltaic power generation part through the cooperation of the set brushing component, the scrubbing component and the driving component, while ensuring that the foam is cleaned before continuing to clean other positions to ensure that the foam is completely removed. The set linkage component can gradually increase the cleaning force when cleaning the same position, thereby ensuring that the parts with more serious dirtiness are strengthened, improving the cleaning efficiency, and avoiding the contamination of the photovoltaic panel by residual foam.

When the touch button 515 is pressed, the output end of the cylinder 723 is controlled to extend and remain for a period of time before contracting.

[0023] In this embodiment, when in use, the fixing frame 1 is moved so that the mounting frame 3 is located directly above the photovoltaic panel to be cleaned, and the mounting frame 2 is driven to rotate by starting the electric push rod 201 so that the mounting frame 2 is parallel to the photovoltaic panel, and the driving shaft 403 is driven to rotate by starting the stepping motor 405, and the driving shaft 403 drives the driving gear 404 to rotate, and the driving gear 404 drives the moving seat 401 to move along the mounting frame 2 by meshing with the rack 402, so that the cleaning brush 602 and the wiping plate 507 abut against the surface of the photovoltaic panel; By connecting the tap water pipe with the water inlet of the water pump 12, and starting the water pump 12, the driving motor 506 and the rotating motor 601, the water pump 12 guides the tap water into the transverse pipe 11, and guides it into the first water outlet cylinder 8, the second water outlet cylinder 9 and the third water outlet cylinder 10 through the transverse pipe 11, and adds a cleaning agent to the first feeding hopper 801, and adds a defoaming agent to the second feeding hopper 901, so that the tap water mixed with the cleaning agent is sprayed out through the nozzle at the bottom of the first water outlet cylinder 8, and cooperates with the rotating motor 601 to drive the connecting shaft 6 and the cleaning agent. The scrubber 602 rotates to scrub the surface of the photovoltaic panel. At the same time, tap water mixed with a defoaming agent is sprayed out through the nozzle at the bottom of the second water outlet cylinder 9 to partially eliminate the foam generated by scrubbing, and the tap water is sprayed out through the nozzle at the bottom of the third water outlet cylinder 10 to further rinse the photovoltaic panel. At the same time, the driving motor 506 drives the rotating shaft 512 to rotate clockwise, and drives the connecting column 504 to perform a clockwise circular motion through the rotating arm 505. The connecting column 504 is connected to the vertical plate 503 by the vertical plate 503. The square plate 516 and the connecting plate 509 are driven to perform a clockwise circular motion, and under the guidance of the lifting plate 511, the vertical rod and the U-shaped rod 510, the square plate 516 does not deflect during the circular motion. The square plate 516 drives the fixed frame 508 to perform a clockwise circular motion, so that the fixed frame 508 moves downward and moves to the left, moves upward and moves to the left, moves upward and moves to the right, and moves downward and moves to the right, that is, the fixed frame 508 first moves to the left during the leftward motion. The wiper plate 507 is squeezed by the downward movement, and then moves upward. During this process, the wiper plate 507 is always in contact with the photovoltaic power generation panel, and the pressing force of the wiper plate 507 increases first and then decreases, so that the wiper plate 507 can scrub the photovoltaic power generation panel to facilitate the removal of foam on the surface. In the process of moving to the right, the fixed frame 508 first moves upward to make the wiper plate 507 disengage from the photovoltaic power generation panel, and then moves downward to contact the photovoltaic power generation panel again, and this reciprocating process is repeated to achieve one-way scrubbing of the photovoltaic power generation panel. When the surface of the photovoltaic power generation panel is scrubbed by the scrubbing component 5, the cleaning agent foam on the surface of the photovoltaic power generation panel causes the wiping board 507 and the photovoltaic power generation panel to slip. As the wiping board 507 wipes off the foam and the foam is washed away by the clean water sprayed from the third water outlet cylinder 10, the friction component between the wiping board 507 and the photovoltaic power generation panel gradually increases, and the fixed frame 508 is blocked while moving to the left, so that the square plate 516 moves to the left relative to the fixed frame 508 and squeezes the return spring 514. When the resistance is large enough, the square plate 516 contacts the touch button 515, thereby controlling the stepping motor 405 to work for a period of time and then shut down, that is, driving the moving seat 401 and the mounting frame 3 to move down along the mounting frame 2 for a distance and then stop, thereby realizing cleaning of another area of ​​the photovoltaic power generation panel; The vertical plate 503 drives the lifting plate 511 and the push plate 707 to move up and down by cooperating with the U-shaped rod 510 while performing circular motion. After the lifting plate 511 moves upward and contacts the lower trapezoidal plate 704, it drives the lower trapezoidal plate 704 to move upward, and pushes the tooth plate 712 and the moving plate to move upward through the lower trapezoidal plate 704. The moving plate 716 drives the side plate 711 to move upward and squeezes the compression spring 713 and the varistor 715. At the same time, the tooth plate 712 moves upward. When the upper trapezoidal plate 703 moves to the left, the upper trapezoidal plate 703 moves downward through the arc connecting plate 702, and the connecting spring 719 is stretched. When the tooth plate 712 moves upward by a distance of an oblique tooth, the upper trapezoidal plate 703 is reset under the elastic force of the connecting spring 719, and the tooth plate 712 is locked again. When the lower trapezoidal plate 704 moves downward, it will not drive the tooth plate 712 to move downward. The tooth plate 712 pushes the lower trapezoidal plate 704 to move to the left through the oblique teeth, and the transverse spring 719 is stretched. 09 is squeezed, so that along with the scrubbing work, the tooth plate 712 and the movable plate 716 intermittently move upward, and gradually increase the squeezing force on the varistor 715, so that the resistance of the varistor 715 is reduced, thereby increasing the power of the rotating motor 601 and the water pump 12, thereby gradually improving the flushing and scrubbing effect, until the touch foam is cleared, the fixed plate 710 contacts the touch button 515 and controls the stepper motor 405 and the cylinder 723 to start, and the servo motor drives The movable seat 401 and the mounting frame 3 move a certain distance. When the mounting frame 3 moves, the abutting wheel 718 abuts against the arc-shaped protrusion of the wave plate 202 and pushes the bracket 701 to move downward, thereby driving the upper trapezoidal plate 703 to move to the left through the cross plate 722 and the arc-shaped connecting plate 702. At the same time, the cylinder 723 drives the connecting rod through the push rod to drive the lower trapezoidal plate 704 to move to the left, so that the upper trapezoidal plate 703 and the lower trapezoid are both released from the fixation of the tooth plate 712, and the movable plate 716 is reset under the action of the compression spring 713.
