Description

Technical Field

[0001] This utility model relates to the field of solar panel cleaning technology, and in particular to a mobile solar panel cleaning device for agricultural and forestry photovoltaic fields. Background Technology

[0002] The mobile solar panel cleaning equipment for agro-forestry photovoltaic (PV) fields is an automated cleaning device specifically designed for agro-forestry PV power generation systems. It efficiently cleans accumulated dust, stains, and impurities from the surface of PV panels, ensuring maximum power generation efficiency. The equipment is mobile, adaptable to various PV sites, and eliminates the need for manual entry into high-risk areas, reducing maintenance costs and safety hazards. Through an intelligent control system, the equipment can clean the PV panels according to their specific needs and uses environmentally friendly materials to minimize environmental impact.

[0003] As shown in the reference case "A Solar Panel Cleaning Device" announcement number "CN222721449U", this utility model has a locking part at the connection between the spray pipe and the spray head. The user can pull the plug rod to make the locking block disengage from the locking groove on the side of the spray head, thereby unlocking the spray head. This locking method avoids the situation where the threaded spray head will loosen and fall off due to the vibration of the spray pipe during the movement of the cleaning vehicle, making it easier for the cleaning vehicle to clean the surface of the solar panel.

[0004] The aforementioned application can lock the spray head by setting a lock, thereby reducing the vibration of the spray pipe caused by the vehicle's movement and reducing the probability of the spray head loosening and falling off. However, this application cannot clean the cleaning roller when cleaning through the spray head, which can easily lead to poor cleaning effect when the device cleans solar panels with a lot of surface dirt, as the cleaning roller is contaminated. Utility Model Content

[0005] Therefore, it is necessary to provide mobile solar panel cleaning equipment for agricultural and forestry photovoltaic fields to address the problem that the cleaning drum is easily contaminated during the cleaning process, resulting in poor subsequent cleaning effects.

[0006] A mobile solar panel cleaning device for a photovoltaic field integrating agriculture and forestry includes: a cleaning vehicle and a wiping mechanism installed at one end of the cleaning vehicle;

[0007] The cleaning mechanism includes a housing located at the other end of the cleaning vehicle, and a cleaning brush and a scraper are provided inside the housing. Both the wiping mechanism and the cleaning mechanism are provided with adjustment components between themselves and the cleaning vehicle.

[0008] In one embodiment, a plurality of first nozzles are fixedly connected to the surface of the housing, and the first nozzles are inclined downward.

[0009] In one embodiment, the surface of the housing is inlaid with a plurality of second nozzles, all of which are positioned toward the cleaning brush.

[0010] In one embodiment, a first water collection pipe and a second water collection pipe are fixedly connected to the surface of the outer casing. The first water collection pipe is connected to a plurality of first nozzles, and the second water collection pipe is connected to a plurality of second nozzles. Both the first water collection pipe and the second water collection pipe are connected to a water pump through a connecting pipe.

[0011] In one embodiment, the scraper is fixedly connected to the inner wall of the housing, and the surface of the scraper is serrated, with the serrations of the scraper contacting the cleaning brush.

[0012] In one embodiment, a drive motor is fixedly connected to one side of the housing, the drive end of the drive motor penetrates into the housing and is fixedly connected to one end of the cleaning brush, and the other end of the cleaning brush is rotatably connected to the inner wall of the other side of the housing.

[0013] In one embodiment, a collection box is provided on the back of the outer casing, and a connecting groove is provided on the surface of the collection box. The collection box is connected to the outer casing through the connecting groove, which is located below the scraper.

[0014] Beneficial effects

[0015] 1. By incorporating a scraper and a second nozzle that sprays water onto the cleaning brush within the cleaning mechanism, the scraper cleans the brush while the cleaning brush itself cleans the solar panel surface, reducing dirt accumulation on the brush surface and minimizing the impact of residual dirt on subsequent solar panel cleaning. Simultaneously, the design of the second nozzle ensures the cleaning brush surface remains clean, reducing interference from contaminants on cleaning efficiency. This improvement allows the device to reduce brush contamination when handling heavily soiled solar panels, thereby enhancing cleaning effectiveness and efficiency.

[0016] 2. By setting an adjustment component, when the device moves to the gaps of the solar panel and causes bumps, the cleaning mechanism will reduce the impact on the surface of the solar panel under the action of the adjustment component. At the same time, the adjustment component can automatically adjust the force of the cleaning mechanism according to the surface condition of the solar panel, so that the cleaning mechanism always keeps close to the surface of the solar panel, thus improving the cleaning effect.

[0029] The following is combined with Figures 1-4 This invention describes a mobile solar panel cleaning device for a photovoltaic field that integrates agriculture and forestry.

[0030] In one embodiment, a mobile solar panel cleaning device for an agricultural and forestry photovoltaic complementary field includes: a cleaning vehicle 100 and a wiping mechanism 200 disposed at one end of the cleaning vehicle 100.

[0031] The cleaning mechanism 300 includes a housing 310 located at the other end of the cleaning cart 100. The housing 310 is equipped with a cleaning brush 320 and a scraper 330. Both the wiping mechanism 200 and the cleaning mechanism 300 are provided with an adjustment component 350 between them and the cleaning cart 100.

[0032] The cleaning vehicle 100 in this device is a relatively mature existing technology. The structure of the cleaning vehicle 100 mainly includes a chassis structure, a power system, a control system, and a cleaning device interface. The chassis is a tracked mobile device, which can increase the stability of the cleaning vehicle 100 when moving on the solar panel surface and reduce damage to the solar panel surface. The power system is used to drive the cleaning vehicle 100. The control system includes a main control board and sensors. The main control board is responsible for receiving instructions, processing data, and controlling the motor operation to realize autonomous navigation and cleaning tasks. The sensors monitor the robot's position and posture in real time to ensure stability and safety during the cleaning process. This device achieves autonomous navigation and precise positioning through GPS system, visual recognition and other technologies. Then the main control board starts the motor, and the power is transmitted to the walking device through the transmission device, so that the device begins to move. During the cleaning process, the main control board adjusts the working status and cleaning intensity of the cleaning device according to the preset program and sensor feedback; the wiping mechanism 200 consists of the outer shell 310 and the wiping roller set inside the outer shell 310. At the same time, the wiping roller is driven by a stepper motor. After the front end of the cleaning vehicle 100 cleans the solar surface, a large amount of water will remain on the surface of the solar. At this time, the wiping mechanism 200 wipes the water on the surface of the solar to reduce the water stains remaining afterward.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a plurality of first nozzles 321 are fixedly connected to the surface of the housing 310, and the first nozzles 321 are inclined downward. A plurality of second nozzles 331 are embedded in the surface of the housing 310, and the second nozzles 331 are all facing the cleaning brush 320. A first water collection pipe 322 and a second water collection pipe 332 are fixedly connected to the surface of the housing 310. The first water collection pipe 322 is connected to the plurality of first nozzles 321, and the second water collection pipe 332 is connected to the plurality of second nozzles 331. Both the first water collection pipe 322 and the second water collection pipe 332 are connected to the water pump through a connecting pipe. A scraper 330 is fixedly connected to the inner wall of the housing 310. The surface of the scraper 330 is serrated, and the serrations of the scraper 330 are in contact with the cleaning brush 320. A drive motor 311 is fixedly connected to one side of the housing 310. The drive end of the drive motor 311 penetrates into the housing 310 and is fixedly connected to one end of the cleaning brush 320. The other end of the cleaning brush 320 is rotatably connected to the other inner wall of the housing 310. A collection box 340 is provided on the back of the outer casing 310. A connecting groove 341 is provided on the surface of the collection box 340. The collection box 340 is connected to the outer casing 310 through the connecting groove 341. The connecting groove 341 is located below the scraper 330.

[0034] In this embodiment, the first water collection pipe 322 and the second water collection pipe 332 of this device are connected to the water pump through a connecting pipe. The connecting pipe is a flexible hose and requires an external water source to be connected to the water pump to send water from the water source into the two water collection pipes. The two sets of nozzles spray water from the two water collection pipes respectively. The serrated position of the scraper 330 is inserted into the cleaning brush 320. When the cleaning brush 320 rotates, the scraper teeth will scrape off the dirt on the surface of the cleaning brush 320. At the same time, the scraper teeth are arc-shaped and the connecting groove 341 is located below the scraper 330, so the dirt scraped off by the scraper 330 will flow into the connecting groove 341 along the inner side of the scraper 330 and flow into the collection box 340 through the connecting groove 341 to prevent sewage from flowing back to the solar panel.

[0035] It should also be noted that the improvement of the cleaning mechanism 300 in this device is mainly reflected in the cleaning part of the cleaning brush 320. The cleaning of the cleaning brush 320 is mainly achieved by spraying water onto the cleaning brush 320 through the second nozzle 331, while the scraper 330 scrapes away the dirt on the surface of the cleaning brush 320. The scraper 330 is located inside the housing 310 and behind the cleaning brush 320, and the second nozzle 331 is embedded in the inner wall of the housing 310, so it will not affect the normal operation of the cleaning brush 320. At the same time, the adjustment mechanism drives the entire cleaning mechanism 300 to adjust, without changing the position of any individual component. In addition, the cleaning mechanism 300 of this device is located at the front of the cleaning cart 100, so it will not change the structure and normal operation of the cleaning cart 100. In summary, the cleaning mechanism 300 of this device will not affect the normal cleaning of the solar panels by the cleaning brush 320.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the adjustment assembly 350 includes connecting blocks 351 that are fixedly connected to both sides of the outer casing 310. Multiple limiting rods 352 are fixedly connected to the inner walls of both sides of the cleaning cart 100 near the outer casing 310. The connecting blocks 351 are slidably connected to the limiting rods 352. A spring 353 is sleeved on the surface of the limiting rod 352. The spring 353 is fixedly connected between the connecting blocks 351 and the inner wall of the cleaning cart 100.

[0037] In this embodiment, two fixing blocks are fixedly connected to both sides of the front end of the cleaning cart 100. The interior of the fixing block is hollow, and the limiting rod 352 is disposed therein. The outer shell 310 is connected to two connecting blocks 351, and the other end of the connecting block 351 is disposed in the fixing block and slidably connected to the limiting rod 352. At the same time, the spring 353 applies pressure to the cleaning mechanism 300 through the connecting block 351, so that the cleaning mechanism 300 is in contact with the solar panel. When the cleaning mechanism 300 moves to a position where the solar surface is uneven, this position may collide with the rotating part of the cleaning brush. When the collision occurs, the cleaning mechanism 300 will compress the spring 353 and move upward, thereby reducing the damage caused by the collision between the cleaning brush 320 and the solar panel.

[0038] Working principle: Before cleaning the solar panel, spray a rotating cleaning agent onto the solar panel. Then, place the device directly on the solar panel that needs cleaning and start the device. After the device is started, the drive motor 311 drives the cleaning brush 320 to rotate counterclockwise. At the same time, the water pump injects water into the two water collection pipes through the connecting pipe. Simultaneously, the first nozzle 321 sprays the water in the first water collection pipe 322 towards the front of the cleaning cart 100, and the second nozzle 331 sprays the water in the second water collection pipe 332 towards the cleaning brush 320. At the same time, the cleaning cart 100 moves the cleaning mechanism 300.

[0039] During the movement of the cleaning mechanism 300, the adjusting component 350 applies a downward pressure to the cleaning mechanism 300, ensuring that the cleaning brush 320 remains in contact with the surface of the solar panel. The first nozzle 321 sprays water towards the front of the cleaning brush 320. As the cleaning vehicle 100 moves, the cleaning brush 320 cleans the surface of the solar panel after the water spray. Simultaneously, as the cleaning brush 320 rotates, the scraper 330 inside the housing 310 scrapes the surface of the cleaning brush 320. At the same time, the second nozzle 331 sprays water onto the surface of the cleaning brush 320. Most of the dirt on the surface of the cleaning brush 320 is scraped off by the scraper teeth of the scraper 330 and flows along the surface of the scraper 330 through the connecting groove 341 into the collection box 340. Meanwhile, another water pump extracts the wastewater from the collection box 340 through the connecting pipe.

[0040] It should be noted that the cleaning cart 100, wiping mechanism 200, drive motor 311, cleaning brush 320 and spring 353 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the cleaning cart 100, wiping mechanism 200 and drive motor 311 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
