DETAILED DESCRIPTION

[0017] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0018] See also Figure 1-4 , an intelligent photovoltaic panel cleaning device, including a device body 1, adsorption tracks 2 are arranged on both sides of the bottom end of the device body 1, the device body 1 is provided with a drone hanging point 3, the front side of the device body 1 is provided with a lighting spotlight 6, the bottom end of the device body 1 is provided with a frame 4, and a cleaning device 5 is arranged inside the frame 4.

[0019] The cleaning device moves by means of the adsorption track 2, which can ensure that the cleaning device can be stably adsorbed on the surface of the photovoltaic panel. The surface of the photovoltaic panel is usually made of glass, and because it is necessary to ensure the sunshine duration, it is often placed at an angle. If the cleaning device uses an ordinary wheel structure, the friction between it and the glass on the surface of the photovoltaic panel is insufficient, and it is easy to slip, resulting in failure of normal cleaning operations.

[0020] The cleaning device 5 includes four screw rods 8, a hard roller brush 9 is provided on the screw rod 8 at the front end, a rotating brush head 13 is provided on the screw rod 8 at one side of the screw rod 8 at the front end, a soft roller brush 16 is provided on the screw rod 8 at the rear end, and an ultrasonic cleaning device 17 is provided on the screw rod 8 at one side of the screw rod 8 at the rear end.

[0021] The cleaning device 5 further includes an air outlet duct 18 , which is disposed at the front end of the hard roller brush 9 , and an air duct rotating shaft 19 is disposed inside the air outlet duct 18 .

[0022] First, the air is blown toward the photovoltaic panel through the air outlet duct 18 to blow down the larger stains or dust particles on the surface of the photovoltaic panel. The wind direction of the cleaning equipment is different according to the different movement orders. Specifically, the cleaning equipment has two movement modes on the surface of the photovoltaic panel (based on the premise of the whole panel cleaning plan), such as Figure 6 shown.

[0023] When the cleaning device moves in the horizontal direction, in order to ensure that the stains on the photovoltaic panel are blown downward, the air outlet duct 18 will be rotated 45 degrees or 90 degrees by the air duct shaft, that is, the air outlet duct 18 faces the lower end of the photovoltaic panel to blow the stains on the panel downward. When the cleaning device moves in the longitudinal direction, during the downward movement, the air outlet duct 18 can directly blow the stains on the panel downward, so the air duct shaft 19 does not need to move. During the upward movement, the air outlet duct 18 will blow the stains on the panel upward, so the air outlet needs to be closed.

[0024] The cleaning device also includes a replaceable battery assembly 20, and the replaceable battery assembly 20 is installed on the upper surface of the cleaning device.

[0025] In this embodiment, fixed points 7 are provided on both sides of the cleaning device 5 , and the fixed points 7 are fixedly mounted on the frames 4 on both sides of the equipment body 1 . The cleaning device 5 is fixedly mounted on the equipment body 1 based on the fixed points 7 .

[0026] In this embodiment, one end of the screw rod 8 is connected to the output shaft of the motor 10, and the motor 10 is used to drive the screw rod 8; The other end of the screw rod 8 is connected to a screw rod connector 11 , and the screw rod connector 11 is used to set the screw rod 8 on the cleaning device 5 .

[0027] In this embodiment, a cleaning liquid nozzle 14 is also provided on one side of the rotating brush head 13, and one end of the cleaning liquid nozzle 14 is connected to a cleaning liquid tank 15 located inside the device body 1, which can utilize its own gravity to continuously and automatically leak cleaning liquid, or actively fill the cleaning liquid by adding a controllable valve on the filling pipe.

[0028] In this embodiment, the ultrasonic cleaning equipment 17 includes a sleeve 21, which is used to fix the screw 8 to ensure that the entire assembly can move laterally on the cleaning equipment and the cleaning equipment itself moves longitudinally, thereby realizing cleaning of any point. The sleeve 21 is sleeved on the surface of the screw 8, and a bracket 22 is provided at the bottom of the sleeve 21. A cleaning liquid box 23 is provided below the bracket 22, and seismic isolation cotton 24 is provided below the cleaning liquid box 23. An ultrasonic vibrator 25 is provided below the cleaning liquid box 23 through the seismic isolation cotton 24. The cleaning liquid box 23 and the ultrasonic vibrator 25 are both installed and fixed through the bracket 22, and a vibration guide plate 26 is provided below the ultrasonic vibrator 25.

[0029] In this embodiment, the ultrasonic cleaning device 17 further includes a hard cleaning block 27 and a soft cleaning block 12 . The vibration guide plate 26 is disposed inside the hard cleaning block 27 , and the soft cleaning block 12 is disposed below the hard cleaning block 27 .

[0030] The hard cleaning block 27 is usually a fiber composite material with a relatively hard texture, or a sponge block, which has a large number of cavities inside. However, the overall structure is relatively hard, ensuring that the transmission of vibration will not be greatly attenuated on the material, while also ensuring that the cleaning liquid can fully penetrate onto the soft cleaning block 12.

[0031] The cleaning liquid is infiltrated into two cleaning blocks through the filling pipe of the cleaning liquid box 23, and the cleaning blocks are pressed against the surface of the photovoltaic panel. The ultrasonic vibrator 25 vibrates at a specific frequency to excite the cleaning blocks to vibrate at a high frequency. At the same time, the cleaning liquid infiltrated in the cleaning blocks is excited to vibrate at a high frequency to generate a large number of bubbles, thereby achieving a relatively thorough cleaning of the surface of the photovoltaic panel.

[0032] The cleaning liquid box 23 can utilize its own gravity to continuously and automatically leak the cleaning liquid, or actively fill the cleaning liquid by adding a controllable valve on the filling pipeline.

[0033] When the ultrasonic vibrator 25 vibrates with a small amplitude and high frequency, the vibration is transmitted outwards, and one side is affected by the vibration isolation cotton 24, so the vibration is mainly transmitted to the vibration guide plate 26. The vibration guide plate 26 directly cooperates with the hard cleaning block 27, so that the vibration is transmitted to the hard cleaning block 27, and finally to the soft cleaning block 12. When the soft cleaning block 12 directly rubs against the surface of the photovoltaic panel, the cleaning liquid is infiltrated thereon, and with the high-frequency vibration, an effect of efficiently cleaning the surface of the photovoltaic panel can be achieved.

[0034] Theoretically, using high-frequency vibration to clean photovoltaic panels can solve most stain problems. However, since ultrasonic cleaning consumes a large amount of cleaning fluid, multiple methods can be used to achieve the cleaning effect.

[0035] Ultrasonic waves clean the surface of photovoltaic panels through vibration, which requires a good vibration medium. The medium must be able to stably transmit the vibration to the surface of the object being cleaned without causing vibration loss during the vibration process, so that the cleaning can be meaningful.

[0036] Specifically, the ultrasonic vibrator 25 first transmits vibration to the hard cleaning block 27 through the vibration guide plate 26, and finally transmits it to the flexible cleaning block 12. In fact, the vibration will be absorbed by the flexible cleaning block 12, and the effect of ultrasonic vibration cannot be achieved.

[0037] It is very simple to reduce the absorption of vibration by the flexible cleaning block 12. The so-called flexible cleaning block 12 is caused by its large deformation. Reducing the deformation of the flexible cleaning block can reduce its absorption of vibration, thereby improving the efficiency of ultrasonic vibration.

[0038] Therefore, water is added to the flexible cleaning block 12, including some hard cleaning blocks of materials. This water is not consumable and its loss during the vibration process is very small. Its purpose is to fill the deformation space of the material with water, so as to better guide the conduction of vibration.

[0039] For the surface to be cleaned, a layer of water is attached to its surface, and the water reciprocates on the surface of the object with high-frequency vibration to achieve the purpose of cleaning.

[0040] Of course, water is constantly being consumed during the cleaning process, but this amount of loss is far less than simply flushing the photovoltaic panels with water.

[0041] In fact, there are two ways to clean the surface of photovoltaic panels using ultrasound. One is to use high-frequency vibration to loosen and disperse the tiny stains attached to the surface of the photovoltaic panels, and then use a rolling brush to brush off the stains.

[0042] Furthermore, ultrasonic vibration is used to vibrate the vibration-conducting medium, so that the vibration-conducting medium itself can scrub the surface of the photovoltaic panel like a brush. In essence, the brush is repeatedly rubbed on the glass surface with high-frequency vibration to achieve the purpose of cleaning.

[0043] After the ultrasonic cleaning is completed, the soft roller brush 16 is used to clean the remaining stains on the cleaned area to achieve an ideal cleaning effect. Based on this, the cleaning device only needs to travel one circle on the photovoltaic panel along a specific track to complete the cleaning of a photovoltaic panel.

[0044] like Figure 7 As shown, in this embodiment, when the device is used, it includes the following process: S1. Image acquisition Collect image information in front of the cleaning equipment to determine the distribution location of stains.

[0045] S2, Blowing dust The airflow drives some dust and debris directly off the photovoltaic panels.

[0046] First, a large amount of dust can be blown away by blowing. Since photovoltaic panels are usually placed at an angle, the air flow can be controlled downward so that the main dust stains can be blown to the ground. When it is the turn of the hard roller brush to scrub, most of the collected dust has been blown away. That is, the blowing stage cleans those stains that are not tightly attached to the photovoltaic panel and are relatively large in volume.

[0047] S3, hard roller brush Use a hard roller brush to scrub the surface of the photovoltaic panel to remove most stains.

[0048] The main targets of scrubbing are the large particles of dirt that are tightly attached to the surface of the photovoltaic panels, including mud, bird droppings, etc. These large particles of dirt with a certain degree of adhesion can be fully scrubbed away by scrubbing with a hard roller brush.

[0049] S4. Position matching Move the fine rotating brush head to the stubborn stains.

[0050] S5. Spraying cleaning fluid The cleaning liquid nozzle sprays the cleaning liquid precisely on the stain and waits for a while for the stain to soften.

[0051] S6, fine cleaning of stubborn stains Use the rotating brush head to precisely scrub stubborn stains.

[0052] For stains that are more difficult to handle, such as bird droppings hardened on the surface of photovoltaic panels, most of these bird droppings will be scrubbed with a hard roller brush, but some will still remain tightly attached to the surface of the photovoltaic panels. At this time, they need to be softened with cleaning fluid and then scrubbed after softening to completely remove these stubborn stains.

[0053] Fine cleaning does not cover the entire cleaning area, but only performs small-scale cleaning on the location of stubbornly attached stains. Prior to this, the cleaning device has already captured and determined the location of the stubborn stains through the image acquisition module. After the cleaning device moves to that location, the stubborn stains are injected and scrubbed with cleaning liquid.

[0054] S7, ultrasonic cleaning Ultrasonic cleaning equipment is used to clean the surface of the photovoltaic panels to remove fine particles attached to the surface of the photovoltaic panels.

[0055] S8, soft roller brush cleaning Use a soft roller brush to perform a final clean on the photovoltaic panel to remove water stains and fine dust produced during cleaning.

[0056] In this embodiment, when the cleaning device is parked on the photovoltaic panel, it has learned the basic size range, tilt angle and degree of dirtiness of the photovoltaic panel through prior exploration, and the specifications of the cleaning device are also known, so it will automatically plan the cleaning path.

[0057] The movement path of the cleaning equipment is related to the cleaning area, vehicle body specifications, and photovoltaic panel size, including lateral and longitudinal movement. The cleaning device is distributed on the bottom edge of the cleaning equipment along the width of the vehicle body. The cleaning equipment moves on the photovoltaic panel, and the photovoltaic panel in the width direction can follow Figure 7The process shown is cleaned. Embodiment 2:

[0058] An intelligent photovoltaic panel cleaning system is used in conjunction with the intelligent photovoltaic panel cleaning equipment described in Example 1, and includes a command center and a transport aircraft. The command center is used to command and dispatch the cleaning equipment and the transport aircraft, while maintaining daily maintenance of the cleaning equipment and the transport aircraft, processing various data collected during the cleaning process, and formulating cleaning strategies; the transport aircraft carries the cleaning equipment based on a drone hanging point, and transports the cleaning equipment to the photovoltaic panel to be cleaned.

[0059] In this embodiment, the system further includes an image acquisition module and a drive control module, and the image acquisition module and the drive control module are both arranged in the cleaning device; The image acquisition module is used to collect image information in front of the cleaning device to determine the distribution position of the stains; The driving control module is used to control the cleaning work of the cleaning equipment.

[0060] The image acquisition module can identify the stains on the path that the cleaning device will pass through, and determine which stains need to be softened by detergent. When the cleaning device is driven over the stain, the cleaning liquid nozzle will spray a specific cleaning liquid at the stain location. Since the cleaning liquid and its kit are integrated on a screw rod, the entire kit can move horizontally in the cleaning area of ​​the cleaning device, and the cleaning device itself can move vertically, so the cleaning liquid can be spread to any position of the entire photovoltaic panel.

[0061] After being softened by the cleaning liquid, the stains on that location will be continuously scrubbed by the rotating brush head, thereby achieving the effect of accurately cleaning the stains in that area.

[0062] In this embodiment, the system also includes an equipment monitoring module, which is used to monitor the battery power of the replaceable battery assembly of the cleaning equipment, the cleaning liquid inventory in the cleaning liquid tank and the cleaning liquid box, and the equipment temperature in real time. When it is found that the working conditions cannot be met, a signal is sent to the command center or the conveyor, and the cleaning equipment is transported back to the command center by the conveyor to replace the battery, clean the roller brush, or add cleaning liquid.

[0063] After the cleaning equipment reaches the photovoltaic panel, it will clean the photovoltaic panel. First, it will use a roller brush to remove the larger stains on the photovoltaic panel, and then use ultrasonic vibration for fine cleaning. This can be repeated several times until the photovoltaic panel is completely clean. For some stubborn stains that are difficult to clean, such as bird droppings attached to the photovoltaic panel, the cleaning liquid is used to soften these stains, and then the stain position is carefully refreshed to achieve point-to-point precise decontamination.

[0064] The cleaning relationship between the cleaning equipment and the photovoltaic panels is as follows Figure 5 shown.

[0065] Taking the lateral movement direction as an example, the cleaning equipment has four positions numbered 1 to 4, where number 1 is the starting position. The conveyor can park the cleaning equipment at the starting position, or the cleaning equipment can drive itself to the starting position for cleaning operations.

[0066] At position 2, the cleaning device turns and moves to the next horizontal path for cleaning. The distance between two adjacent paths is the distance of the cleaning range of the cleaning machine. It is necessary to ensure that the cleaning range overlaps so that the photovoltaic panels can be fully cleaned.

[0067] When the machine moves to position 4, it means that the machine has completed the cleaning of the entire photovoltaic panel. At this time, you can summon a transport plane to transport across panels, or return to the command center.

[0068] The beneficial effects of the present invention are: This intelligent photovoltaic panel cleaning equipment and system integrates multiple cleaning technologies, such as hard roller brushes, rotating brush heads, ultrasonic cleaning, and replaceable battery components, to achieve efficient and fully automatic cleaning of photovoltaic panels. The image acquisition module and drive control module in the system provide accurate stain detection and cleaning control, ensuring the comprehensiveness and efficiency of the cleaning process. Compared with existing technologies, this system greatly improves cleaning efficiency, reduces manual intervention, and can operate stably in complex environments, significantly improving the power generation efficiency of photovoltaic panels.
