Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning technology, specifically to a photovoltaic cleaning inspection system. Background Technology

[0002] With increasing energy scarcity, photovoltaic (PV) power generation has been widely adopted. Larger PV power plants employ a massive number of PV panels. These panels are typically installed outdoors in areas exposed to intense sunlight, enduring daily wind, rain, and sun exposure. They are also frequently affected by bird droppings, resulting in a significant accumulation of dirt and grime on their surfaces. This reduces PV efficiency, hinders heat dissipation, and corrodes the panels, shortening their lifespan. Therefore, regular inspection, cleaning, and maintenance of PV panels are essential. A search revealed existing technology (publication number: CN220190831U), which describes "a photovoltaic module inspection device. This photovoltaic module inspection device includes a control device and an inspection and cleaning device. The control device has a display screen and an operating mechanism. The inspection and cleaning device is connected to the control device and includes a robotic arm, one end of which is connected to the control device, and the other end of which is connected to an inspection mechanism and a cleaning mechanism. The robotic arm controls the movement of the inspection mechanism and the cleaning mechanism in six degrees of freedom through the operating mechanism. The inspection mechanism includes an image acquisition device and a lighting lamp; image information acquired by the image acquisition device is sent to the display screen for display. The cleaning mechanism includes a gas-liquid spray head and a wiping tool assembly. This photovoltaic module inspection device has the advantage of improving the efficiency of inspection and cleaning, ensuring the consistency between the condition of the photovoltaic panels during cleaning and the information obtained during inspection, and achieving thorough cleaning of stained photovoltaic panels."

[0003] While existing photovoltaic module inspection equipment has achieved automatic cleaning and inspection of photovoltaic panels, it still has some shortcomings: The image acquisition device and the gas-liquid jet head of the existing photovoltaic module inspection equipment are too close, which makes it easy for water vapor generated around the jet head and sewage reflected by the photovoltaic panel to directly splash onto the image acquisition device, thus affecting the clarity of image acquisition. Secondly, the wiping tool component is directly immersed in water for cleaning after it gets dirty, which not only results in poor cleaning effect, but also requires multiple treatments of sewage and replacement of cleaning water. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a photovoltaic cleaning and inspection system is provided to solve the problems of image acquisition device contamination affecting image clarity and deviation in cleaning effect of wiping tools in existing photovoltaic module inspection equipment.

[0005] To achieve the above objectives, a photovoltaic cleaning inspection system is provided, comprising: a control device, a cleaning device, a cleaning component, and a scanning component. A first robotic arm and a second robotic arm are connected to one side of the control device, and a flatbed truck is connected to the bottom of the control device. The cleaning device is located below the second robotic arm and is situated on the flatbed truck. The cleaning device includes a water tank and a cleaning tank. A gas-liquid jet nozzle is connected to the execution end of the first robotic arm, and the gas-liquid jet nozzle is connected to the water tank via a pipe and a water pump. The scanning component is connected to the execution end of the first robotic arm, while the cleaning component is connected to the execution end of the second robotic arm.

[0006] Furthermore, a water supply pipe is connected between the water supply tank and the cleaning tank, and an electromagnetic valve is installed in the water supply pipe.

[0007] Furthermore, the cleaning box is equipped with a fixing plate, and a rubber rod is connected to the upper side of the fixing plate. At the same time, a through hole is opened inside the fixing plate.

[0008] Furthermore, a guide bucket is connected to the lower side of the fixed plate, and a drain pipe is connected to the lower end of the guide bucket. The drain pipe passes downward through the flatbed truck, and a drain valve is installed in the drain pipe.

[0009] Furthermore, the cleaning assembly includes a mounting plate, with a motor mounted on one side of the mounting plate and a rotating shaft rotatably connected to the other side of the mounting plate, with one end of the rotating shaft connected to the motor.

[0010] Furthermore, the end of the rotating shaft away from the motor is connected to a turntable, and the outer end face of the turntable is provided with a cleaning cotton, which is designed as a hemispherical structure.

[0011] Furthermore, the scanning assembly includes a mounting rod connected to the first robotic arm, and a protective cover is mounted on the outside of the mounting rod. An image acquisition device is provided inside the protective cover, and an LED bead is provided on the outside of the image acquisition device.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In use, the control device controls the first and second robotic arms to work together. First, the image acquisition unit of the first robotic arm drive scanning component is started to scan and inspect the appearance of the photovoltaic panel. Then, water is sprayed onto the photovoltaic panel through the gas-liquid jet head to achieve a preliminary cleaning effect. Then, the motor and turntable of the second robotic arm drive cleaning component are started to move to the surface of the photovoltaic panel, so that the turntable is rotated by the motor and then the photovoltaic panel is cleaned with cleaning cotton.

[0014] 2. The protective cover included in the scanning component protects the image acquisition unit inside, preventing water vapor generated around the gas-liquid jet head from affecting the image acquisition unit's imaging clarity. It also prevents damage to the image acquisition unit in case of accidental operation of the first robotic arm and collision with the photovoltaic panel or foreign objects, thus providing a certain degree of protection.

[0015] 3. After the cleaning cotton gets dirty, put clean water from outside into the cleaning tank through the water replenishment tank and water replenishment pipe until it covers the rubber rod. At this time, operate the second robotic arm to extend it downward into the cleaning tank, and at the same time start the motor to drive the turntable to rotate until the cleaning surface on the underside of the turntable contacts the rubber rod. Keep the turntable in contact with water, so as to improve the cleaning effect through the friction between the rubber rod and the cleaning cotton. Then, open the drain valve and release the wastewater after cleaning through the guide bucket and drain pipe to facilitate the discharge of wastewater. Attached Figure Description

The cleaning device 2 is located below the second robotic arm 12 and is located on the flatbed truck. The cleaning device 2 includes a water tank 21 and a cleaning tank 23. A gas-liquid jet head 4 is connected to the execution end of the first robotic arm 11, and the gas-liquid jet head 4 is connected to the water tank 21 through a pipe and a water pump. The scanning component 5 is connected to the execution end of the first robotic arm 11, and the cleaning component 3 is connected to the execution end of the second robotic arm 12.

[0022] In this embodiment, the control device 1, the cleaning device 2, the cleaning component 3, and the scanning component 5 constitute the main structure of the photovoltaic cleaning inspection system involved in this application.

[0023] The connection and driving method between the control device 1 and the first robotic arm 11 and the second robotic arm 12 are consistent with the prior art, and the second robotic arm 12 is located below the first robotic arm 11.

[0024] like Figure 2 As shown, a water supply pipe 22 is connected between the water supply tank 21 and the cleaning tank 23, and an electromagnetic valve is installed in the water supply pipe 22. The cleaning tank 23 is provided with a fixing plate 25, and a rubber rod 24 is connected to the upper side of the fixing plate 25. At the same time, a through hole 26 is opened inside the fixing plate 25. A guide bucket 27 is connected to the lower side of the fixing plate 25, and a drain pipe 28 is connected to the lower end of the guide bucket 27. The drain pipe 28 passes downward through the flatbed truck, and a drain valve 29 is installed in the drain pipe 28.

[0025] Specifically, the cleaning tank 23 is designed as a cylindrical structure, and the rubber rod 24 is made of soft rubber, which provides bidirectional protection when in contact with the turntable 34.

[0026] like Figure 3 As shown, the cleaning component 3 includes a mounting plate 32, and a motor 31 is mounted on one side of the mounting plate 32. A rotating shaft 33 is rotatably connected to the other side of the mounting plate 32. One end of the rotating shaft 33 is connected to the motor 31, and a turntable 34 is connected to the end of the rotating shaft 33 away from the motor 31. A cleaning cotton 35 is provided on the outer end face of the turntable 34, and the cleaning cotton 35 is a hemispherical structure.

[0027] Specifically, the motor 31 is equipped with a protective shell on its outer side, and when the turntable 34 contacts the rubber rod 24, the motor 31 is located outside the cleaning tank 23. Thus, during cleaning, the water supply pipe 22 can be opened at the same time as the drain pipe 28, achieving the effect of rinsing and draining at the same time.

[0028] like Figure 4As shown, the scanning component 5 includes a mounting rod 51 connected to the first robotic arm 11, and a protective cover 52 is mounted on the outside of the mounting rod 51.

Meanwhile, the inner port of the protective shell faces the camera of the image acquisition device 54.

[0030] In use, the control device controls the first and second robotic arms to work together. First, the first robotic arm drives the image acquisition unit, which scans and inspects the photovoltaic panel. Then, water is atomized and sprayed onto the photovoltaic panel through the gas-liquid jet head to achieve a preliminary cleaning effect. Next, the second robotic arm drives the motor and turntable, which move to the surface of the photovoltaic panel. The motor drives the turntable to rotate, and the photovoltaic panel is cleaned with cleaning cotton. When the cleaning cotton gets dirty, clean water is added to the cleaning tank through the water tank and water pipe until it covers the rubber rod. At this time, the second robotic arm is operated to extend it downward into the cleaning tank, and the motor is started to drive the turntable to rotate until the cleaning surface on the underside of the turntable contacts the rubber rod. The turntable is kept in contact with water, thereby improving the cleaning effect through the friction between the rubber rod and the cleaning cotton. Finally, the drain valve is opened, and the wastewater after cleaning is released through the guide bucket and drain pipe.

[0031] The photovoltaic cleaning and inspection system of this utility model can effectively solve the problems of existing photovoltaic module inspection equipment, such as image acquisition device contamination affecting image clarity and deviation in cleaning effect of wiping tools. Based on the existing photovoltaic cleaning and inspection system technology, it ensures that the image acquisition device is not contaminated, enhances the cleaning effect of wiping tools, and facilitates more convenient sewage discharge.
