Description

Technical Field

[0001] This invention relates to the technical field of photovoltaic equipment, and in particular to a waterless cleaning device and system for photovoltaic modules. Background Technology

[0002] With the increasing global emphasis on renewable energy, photovoltaic solar energy, as a clean and renewable energy form, has been widely used and developed. As the core component of a photovoltaic power station, the power generation efficiency and lifespan of photovoltaic modules are directly affected by the cleanliness of the module surface. The accumulation of pollutants such as dust on the surface of photovoltaic modules not only blocks sunlight and reduces the amount of sunlight absorbed by the photovoltaic modules, thereby reducing power generation, but also increases the diffuse reflection of sunlight, further affecting the conversion efficiency of photovoltaic modules. In addition, these pollutants may also hinder the heat dissipation of photovoltaic modules, causing the module temperature to rise, further reducing the conversion efficiency and shortening the lifespan of photovoltaic modules.

[0003] To ensure the power generation efficiency and lifespan of photovoltaic modules, regular cleaning is crucial. However, traditional cleaning methods, such as mechanical washing and manual wiping, have many shortcomings when dealing with large and medium-sized photovoltaic power plants. While mechanical washing can be automated, the surface of photovoltaic modules is exposed to direct sunlight for extended periods during power generation, resulting in high temperatures. Washing under these conditions may directly damage the quality and lifespan of the modules. Manual wiping, on the other hand, requires significant manpower and resources, is time-consuming, and has low cleaning efficiency.

[0004] Therefore, traditional cleaning methods have significant limitations in terms of cleaning time and efficiency. Summary of the Invention

Through advanced pressurized air blowing technology, it efficiently and safely replaces traditional mechanical water washing and manual wiping methods, achieving waterless and efficient cleaning of photovoltaic modules. This design not only significantly improves the power generation efficiency of photovoltaic power plants and effectively extends the service life of photovoltaic modules, but also greatly reduces the cost and time investment of cleaning operations.

[0046] The following description, in conjunction with the accompanying drawings, describes a waterless cleaning device and system for photovoltaic modules according to an embodiment of the present invention.

[0047] like Figures 1-9 As shown, an embodiment of the present invention provides a waterless cleaning device for photovoltaic modules, including a mounting frame 1 and photovoltaic panels 2 uniformly mounted on the top of the mounting frame 1, and further including a waterless cleaning device 3 disposed on the mounting frame 1, the waterless cleaning device 3 comprising:

[0048] The intelligent drive component 4 includes a mounting frame 41, a controller 42, a dual-axis motor 43, and a reciprocating conveying mechanism 44. The mounting frame 41 is fixedly connected to the bottom center of the mounting plate frame 1. One end of the mounting frame 41 extends out of the bottom of the mounting plate frame 1 and then bends upward to form a hook-shaped overlapping part 411. The bottom of the overlapping part 411 is fixedly connected to the top of the mounting frame 41. The controller 42 and the dual-axis motor 43 are respectively disposed inside the overlapping part 411. The reciprocating conveying mechanism 44 is disposed on the top of the mounting plate frame 1 and is connected to the output end of the dual-axis motor 43.

[0049] The waterless cleaning component 5 includes an installation roller 51, a dust thickness detection mechanism 52, a pressurized air blowing mechanism 53, a hot spot detection mechanism 54, and a marking mechanism 55. The installation roller 51 is mounted on the reciprocating conveying mechanism 44 and is located on one side of the top of the mounting plate frame 1.

[0050] The middle set of photovoltaic panels 2 located at the top of the mounting frame 1 is used to power the controller 42. The dual-axis motor 43, dust thickness detection mechanism 52, pressurized air blowing mechanism 53, hot spot detection mechanism 54 and marking mechanism 55 are connected to the controller 42 through the bus system to realize data transmission and control command reception.

[0051] It should be noted that the mounting plate frame 1 described in this embodiment also includes a triangular mounting base (not shown in the figure), and the mounting plate frame 1 is mounted on the mounting surface of the triangular mounting base.

[0052] It should also be noted that the controller 42 described in this embodiment has a built-in timing module (not shown in the figure). The timing module is used to set the time to realize the timed cleaning operation. The controller 42 also has a built-in wireless communication module (not shown in the figure). The controller 42 is wirelessly connected to the host computer through the wireless communication module to realize data transmission and control command reception.

[0055] It should also be noted that the dual-axis motor 43 described in this embodiment is provided with an encoder on its surface and is electrically connected to the controller 42. The encoder is used to detect the number of rotations of the dual-axis motor 43 in real time.

[0056] Specifically, this invention features a rationally designed waterless cleaning device 3 that cleverly utilizes the self-generated energy of the photovoltaic panel 2. Through advanced pressurized air blowing technology, it efficiently and safely replaces traditional mechanical water washing and manual wiping methods, achieving waterless and efficient cleaning of the photovoltaic modules. This design not only significantly improves the power generation efficiency of the photovoltaic power station and effectively extends the service life of the photovoltaic modules, but also greatly reduces the cost and time investment in cleaning operations. This invention innovatively designs a waterless cleaning component 5, which integrates multiple advanced functions, including an installation roller 51, a dust thickness detection mechanism 52, a pressurized air blowing mechanism 53, a hot spot detection mechanism 54, and a marking mechanism 55. These mechanisms are cleverly arranged around the surface of the installation roller 51, through… The rotation of the mounting roller 51 enables seamless switching between various mechanisms, greatly improving the flexibility and efficiency of cleaning operations. The dust thickness detection mechanism 52 employs dual detection technology to accurately measure the dust and powder accumulation on the surface of the photovoltaic panel 2, ensuring data accuracy and reliability. This high-precision detection provides a solid foundation for subsequent cleaning work, with significant results. The pressurized air blowing mechanism 53 utilizes advanced pressurized air blowing technology, abandoning traditional mechanical water washing and manual wiping methods, achieving waterless and efficient cleaning of the photovoltaic modules. This cleaning method is not only environmentally friendly and energy-saving but also avoids potential damage to the photovoltaic modules from moisture, improving cleaning safety and efficiency. The hot spot detection mechanism 54 can detect not only the hot spots on the photovoltaic panel 2... The waterless cleaning component 55 of this invention can simultaneously monitor hot spot phenomena, dust accumulation, and the cleaning effect, achieving multi-functional integration. This feature helps to promptly detect and address potential problems on the photovoltaic panel 2, ensuring the stable operation of the photovoltaic system. For photovoltaic panels 2 that are difficult to clean or malfunction, the marking mechanism 55 can automatically mark them, allowing operators to quickly locate and take appropriate measures. This design greatly reduces the labor intensity of operators, improves work efficiency, and facilitates subsequent maintenance and management. By integrating multiple advanced functions, the waterless cleaning component 5 of this invention achieves efficient, precise, and waterless cleaning of the photovoltaic panel 2, while reducing labor costs and improving overall performance, demonstrating significant technological innovation and practicality. In terms of usability, this invention is equipped with an intelligent drive component 4, which can precisely control the position and movement speed of the waterless cleaning component 5, thereby achieving meticulous cleaning of the photovoltaic panel 2. This highly automated control method not only significantly improves cleaning efficiency but also effectively reduces labor costs, demonstrating excellent performance. The intelligent drive component 4 of this invention also includes an angle self-switching mechanism 446. During the operation of the waterless cleaning component 5, this mechanism can automatically and smoothly switch between the dust thickness detection mechanism 52, the pressurized air blowing mechanism 53, the hot spot detection mechanism 54, and the marking mechanism 55 according to a preset program plan.

[0057] In use, the dual-axis motor 43 receives commands and runs at regular intervals. The operation of the dual-axis motor 43 drives the reciprocating conveyor mechanism 44, which in turn drives the installation roller 51 in the waterless cleaning component 5 to move back and forth on the top of the photovoltaic panel 2. In the initial state, the dust thickness detection mechanism 52 is aligned with the photovoltaic panel 2. During the movement, the dust thickness detection mechanism 52 detects the dust and particulate matter on the surface of the photovoltaic panel 2 and sends the detection data to the controller 42. The controller 42 determines the dust and particulate matter level based on the detection data and controls the cleaning intensity of the pressurized air blowing mechanism 53 according to the dust and particulate matter level. When the dust...

[0058] After the thickness detection mechanism 52 resets to its origin, the angle switching mechanism 446 is passively triggered to operate, driving the installation roller 51 to rotate.

[0059] The pressurized air blowing mechanism 53 is positioned downwards and aligned with the photovoltaic panel 2. During its movement, the pressurized air blowing mechanism 53 blows away dust and particulate matter from the surface of the photovoltaic panel 2. When the pressurized air blowing mechanism 53 returns to its original position, the angle self-switching mechanism 446 is passively triggered and rotates, causing the installation roller 51 to rotate. This aligns the hot spot detection mechanism 54 downwards and with the photovoltaic panel 2. During its movement, the hot spot detection mechanism 54 not only detects hot spots on the photovoltaic panel 2 but also monitors the accumulation of dust and particulate matter and the effectiveness of cleaning, achieving multi-functional integration. When the hot spot detection mechanism 54 returns to its original position, the angle self-switching mechanism 446... Mechanism 446 is passively triggered to run, driving the installation roller 51 to rotate, so that the marking mechanism 55 faces downward and is aligned with the photovoltaic panel 2. The controller 42 determines whether there are things that are difficult to clean or whether there is a malfunction on the surface of the photovoltaic panel 2 based on the detection data of the dust thickness detection mechanism 52 and the hot spot detection mechanism 54. When it is determined that there are things that are difficult to clean or a malfunction on the surface of the photovoltaic panel 2, the controller 42 controls the marking mechanism 55 to run and mark the position of the photovoltaic panel 2, so that the operator can quickly locate and take corresponding measures. When the marking mechanism 55 returns to the origin, the dual-axis motor 43 receives the command to stop running.

[0060] In one embodiment of the present invention, such as Figure 1As shown, the reciprocating conveying mechanism 44 includes an upper end seat 441, a lower end seat 442, a transmission rod 443, a reciprocating lead screw 444, and a movable slide 445. The upper end seat 441 is symmetrically and fixedly connected to the top of the mounting plate frame 1 and located outside the overlapping part 411. The lower end seat 442 is symmetrically and fixedly connected to the end of the mounting plate frame 1 away from the overlapping part 411.

[0061] The surface of the mounting plate 442 is corresponding to the position of the upper end seat 441. The transmission rod 443 is rotatably connected between the overlapping part 411 and the upper end seat 441. One end of the transmission rod 443 passes through the interior of the overlapping part 411 and is connected to the output end of the dual-axis motor 43. The other end of the transmission rod 443 passes through the interior of the upper end seat 441. The reciprocating screw 444 is rotatably connected between the lower end seat 442 and the upper end seat 441. One end of the reciprocating screw 444 passes through the interior of the upper end seat 441. The surface of the reciprocating screw 444 that passes through the interior of the upper end seat 441 and the surface of the transmission rod 443 that passes through the interior of the upper end seat 441 are respectively provided with bevel gears, which mesh with each other. The movable slide 445 is threadedly connected to the outer surface of the reciprocating screw 444 and is horizontally slidably connected to the top of the mounting plate frame 1. The two ends of the mounting roller 51 are respectively rotatably connected between the two sets of movable slides 445.

[0062] It should be noted that the bevel gear described in this embodiment is not shown in the diagram.

[0063] Specifically, the structure and connection relationship of the reciprocating conveying mechanism 44 are further explained. The reciprocating conveying mechanism 44 is set to drive the waterless cleaning component 5 to move back and forth, so as to facilitate the inspection and cleaning of the surface of the photovoltaic panel 2.

[0064] In use, the dual-axis motor 43 receives a command to run. The operation of the dual-axis motor 43 synchronously drives the transmission rod 443 to rotate. The rotation of the transmission rod 443 synchronously drives the reciprocating screw 444 to rotate through the bevel gear. The rotation of the reciprocating screw 444 synchronously drives the moving slide 445 to move back and forth. The movement of the moving slide 445 synchronously drives the waterless cleaning component 5 to move back and forth.

[0065] In one embodiment of the present invention, such as Figure 3As shown, the movable slide 445 has a built-in angle self-switching mechanism 446, which is connected to the mounting roller 51. The angle self-switching mechanism 446 includes a protruding rod 4461, a spring 4462, a sliding toothed plate 4463, a drive gear 4464, and a one-way transmission 4465. The protruding rod 4461 is slidably connected to the side surface of the movable slide 445 near the lower end seat 442. One end of the protruding rod 4461 contacts the surface of the lower end seat 442, and the other end of the protruding rod 4461 penetrates into the movable slide 4465. Inside the slide 445, a spring 4462 is fixedly connected to the inner wall of the slide 445. A sliding toothed plate 4463 is fixedly connected to one end surface of the protrusion 4461 that penetrates into the interior of the slide 445 and is horizontally slidably connected to the inner wall of the slide 445. A drive gear 4464 is rotatably connected to the inner wall of the slide 445 and meshes with the sliding toothed plate 4463. One end of the central shaft of the drive gear 4464 is connected to one end of the central shaft of the mounting roller 51 through a one-way transmission 4465.

[0066] It should be noted that the one-way drive 4465 described in this embodiment is a ratchet-type one-way drive.

[0067] Specifically, the structure and connection relationship of the movable slide 445 are further explained. By setting an angle self-switching mechanism 446 on the movable slide 445, the dust thickness detection mechanism 52, the pressurized air blowing mechanism 53, the hot spot detection mechanism 54 and the marking mechanism 55 can be automatically switched. The operation is simple and the effect is good.

[0068] In use, when the protruding rod 4461 contacts the surface of the lower end seat 442, it is squeezed by the lower end seat 442 and moves towards the inside of the movable slide 445, compressing the spring 4462. The movement of the protruding rod 4461 synchronously drives the sliding toothed plate 4463 to move, and drives the drive gear 4464 to rotate. Since a one-way transmission 4465 is set between the drive gear 4464 and the central axis of the mounting roller 51, the mounting roller 51 will not rotate. When the protruding rod 4461 separates from the surface of the lower end seat 442, the protruding rod 4461 and the sliding toothed plate 4463 automatically reset due to the elastic force of the spring 4462. The reset of the sliding toothed plate 4463 synchronously drives the drive gear 4464 to rotate in the opposite direction. The reverse rotation of the drive gear 4464 synchronously drives the mounting roller 51 to reverse through the one-way transmission 4465, thereby switching the dust thickness detection mechanism 52 to the pressurized air blowing mechanism 53, which has a good effect.

[0069] In one embodiment of the present invention, such as Figure 5As shown, the dust thickness detection mechanism 52 includes a first mounting bracket 521, an electrical sensor 522, and an ultrasonic sensor 523. The first mounting bracket 521 is uniformly fixed in the slots on the surface of the mounting roller 51 by elastic clips 1000. The electrical sensors 522 are uniformly arranged on the surface of the first mounting bracket 521, and the ultrasonic sensors 523 are uniformly arranged on the surface of the first mounting bracket 521 and located between adjacent sets of electrical sensors 522. Both the electrical sensors 522 and the ultrasonic sensors 523 have built-in wireless communication modules. The electrical sensors 522 and the ultrasonic sensors 523 are wirelessly connected to the controller 42 through the wireless communication modules to realize data transmission and control command reception.

[0070] Specifically, the structure and connection relationship of the dust thickness detection mechanism 52 will be further explained. The dust thickness detection mechanism 52 has a dual detection function, which can effectively detect dust and particulate matter on the surface of the photovoltaic panel 2. The dual detection can ensure the detection accuracy and the effect of use.

[0071] In use, the moving installation roller 51 synchronously drives the first mounting bracket 521, the electrical sensor 522, and the ultrasonic sensor 523 to move. During the movement, the electrical sensor 522 and the ultrasonic sensor 523 detect dust and particulate matter on the surface of the photovoltaic panel 2, respectively. The electrical sensor 522 measures the dust by measuring the change in the conductivity of the dust. Dust affects the stability of the electric field and the performance of the current. The sensor can measure the change in conductivity and determine the dust content by calculation. The ultrasonic sensor 523 can measure dust by using ultrasonic waves. Its principle is to use the propagation characteristics of ultrasonic waves in the air. When it encounters dust particles, it will scatter and reflect. The sensor receives these signals to determine the thickness of the dust.

[0072] In one embodiment of the present invention, such as Figure 3 and Figure 6 As shown, the pressurized air blowing mechanism 53 includes a second mounting bracket 531, an air knife 532, an air tank 533, and an air compressor 534. The second mounting bracket 531 is evenly engaged and fixed in the slot on the surface of the mounting roller 51 by elastic clips 1000. The air knife 532 is obliquely disposed on the surface of the second mounting bracket 531. The air tank 533 and the air compressor 534 are respectively disposed on the inner wall of the mounting frame 41 and connected to each other. The air tank 533 is connected to the air knife 532 through an air supply pipe. A first solenoid valve is disposed on the air supply pipe. The air compressor 534 and the first solenoid valve are respectively connected to the controller 42 through a bus system to realize data transmission and control command reception.

[0073] It should be noted that the gas storage tank 533 described in this embodiment includes a pressure detection mechanism (not shown in the figure). The pressure detection mechanism is connected to the controller 42 through a bus system to realize data transmission and control command reception. When the pressure detection mechanism detects that the gas inside the gas storage tank 533 is reduced, it sends the data to the controller 42, and the controller 42 controls the air compressor 534 to run and fill the gas storage tank 533 with gas.

[0074] It should be noted that the mounting frame 41 described in this embodiment is provided with an air intake grille on its surface, and a dustproof net is provided on the inner side of the air intake grille.

[0075] Specifically, the structure and connection relationship of the pressurized air blowing mechanism 53 are further explained. The pressurized air blowing mechanism 53 cleans the surface of the photovoltaic panel 2 by pressurized air blowing, which effectively replaces the traditional manual operation and water washing operation, reduces labor intensity, improves work efficiency, and has a good effect.

[0076] In use, the first solenoid valve opens upon receiving a command, allowing compressed gas inside the gas storage tank 533 to be injected into the air knife 532 through the gas delivery pipe. The air knife 532 then blows the gas onto the surface of the photovoltaic panel 2, cleaning the dust and particulate matter from the surface.

[0077] When the pressure detection mechanism on the gas storage tank 533 detects that the gas inside the gas storage tank 533 has decreased, it sends the data to the controller 42. The controller 42 then controls the air compressor 534 to run and fill the gas storage tank 533 with gas, resulting in good performance.

[0078] In one embodiment of the present invention, such as Figure 7 As shown, the hot spot detection mechanism 54 includes a third mounting base 541 and a thermal imaging sensor 542. The third mounting base 541 is uniformly fixed in the slots on the surface of the mounting roller 51 by elastic clips 1000. The thermal imaging sensor 542 is uniformly disposed on the surface of the third mounting base 541, and the thermal imaging sensor 542 has a built-in wireless communication...

[0079] The thermal imaging sensor 542 is connected to the controller 42 via a wireless communication module to achieve data transmission and control.

[0080] Receiving instructions.

[0081] Specifically, the structure and connection relationship of the hot spot detection mechanism 54 are further explained. The hot spot detection mechanism 54 uses thermal imaging technology to detect the surface of the photovoltaic panel 2. It has the following functions: First, hot spot detection. By capturing the thermal distribution image of the surface of the photovoltaic panel 2 through the thermal imaging sensor 542, areas with abnormal temperatures, i.e., hot spots, can be intuitively identified. Second, dust and particulate matter detection. In addition to hot spot detection, the hot spot detection mechanism 54 can also determine whether there are foreign objects such as dust and particulate matter on the surface of the photovoltaic panel 2 by analyzing the temperature distribution differences in the infrared thermal imaging image. Third, cleaning effect judgment. After cleaning the dust and particulate matter on the surface of the photovoltaic panel 2, the hot spot detection mechanism 54 can be used to judge the cleaning effect. By comparing the infrared thermal imaging images before and after cleaning, the quality and effect of the cleaning work can be intuitively evaluated. Through its precise structural design and connection relationship, as well as its powerful thermal imaging detection function, the hot spot detection mechanism 54 achieves comprehensive, efficient and accurate detection of the surface of the photovoltaic panel 2, and has good performance.

[0082] In one embodiment of the present invention, such as Figure 4 and Figure 8 As shown, the marking mechanism 55 includes a fourth mounting base 551 and a nozzle 552. The fourth mounting base 551 is evenly engaged and fixed within a groove on the surface of the mounting roller 51 by an elastic clip 1000.

[0083] The nozzles 552 are evenly distributed on the surface of the fourth mounting base 551. Each nozzle 552 includes a second solenoid valve. The second solenoid valve is connected to the controller 42 through a built-in wireless communication module to realize data transmission and control command reception.

[0084] It should be noted that the number of the first mounting bracket 521, the second mounting bracket 531, the third mounting bracket 541 and the fourth mounting bracket 551 described in this embodiment are equal to the number of photovoltaic panels 2, and their positions correspond to each other.

[0085] It should be noted that, in this embodiment, white boards (not shown in the figure) are evenly arranged on the top side of the mounting bracket 1 near the lower end seat 442. The number of white boards is equal to that of the nozzles 552, and their positions correspond accordingly. By cleverly utilizing the characteristics of the white boards, they serve as a visual indicator of chemical reactions. Specifically, multiple sets of nozzles 552 are configured to spray their own unique chemical agents onto these white boards. These chemical agents are carefully selected and proportioned to ensure that each agent can induce a specific color change upon contact with the white board. This color change is not only clearly distinguishable, but also... The colors caused by each chemical agent are unique, enabling intuitive identification and differentiation of chemical agent types. In this way, operators can quickly and accurately determine which chemical agents have been applied to the whiteboard and their corresponding color changes. This not only improves work efficiency but also greatly reduces the potential risks caused by misjudgment or confusion of chemical agents. By cleverly combining the whiteboard and the 552 nozzle arrangement, we provide users with an intuitive and easy-to-use identification system, enabling staff to quickly identify faulty or pending photovoltaic panels 2, with good results.

[0086] Specifically, the structure and connection relationship of the marking mechanism 55 will be further explained. As a key component of the entire system, the marking mechanism 55 undertakes the important task of accurately marking photovoltaic panels 2 that are difficult to clean or have hot spots 2. This design aims to help staff quickly and accurately locate the problematic photovoltaic panels 2 during inspection or maintenance, thereby significantly improving work efficiency.

[0087] Specifically, the marking mechanism 55 mainly consists of a nozzle 552, a chemical storage and supply pipeline, and a solenoid valve for precise control of chemical spraying. The nozzles 552 are carefully arranged on the fourth mounting base 551 to ensure they can cover all critical areas on the photovoltaic panel 2. When the dust thickness detection mechanism 52 repeatedly detects a high dust thickness parameter in the set area of ​​the photovoltaic panel 2, the controller 42 receives the data and determines that there is something difficult to clean on this photovoltaic panel 2, requiring manual cleaning by the inspection personnel. In addition to sending information to the host computer via the wireless communication module, it also controls the second solenoid valve on the nozzle 552 corresponding to the photovoltaic panel 2 to open, allowing the chemical agent to be sprayed quantitatively from the nozzle 552 onto the white panel. After the white panel surface is sprayed with the chemical agent, it displays a color corresponding to the information to be cleaned. When the hot spot detection mechanism 54 detects a hot spot on the photovoltaic panel 2, it can determine that there is dust or particulate matter on the photovoltaic panel 2 and identify the corresponding area of ​​the dust or particulate matter. It can also determine that there is a fault in the photovoltaic panel 2 by comparing the dust with the surface of the panel.

[0088] The thickness testing agency 52 compares the data. If the data matches, it can be determined that it is dust or particulate matter. If the data differs,

[0089] The issue is then determined to be a fault in photovoltaic panel 2. After determining that photovoltaic panel 2 is faulty, controller 42, in addition to sending a message to the host computer via the wireless communication module,

[0090] In addition to sending information, it also controls the opening of the second solenoid valve on the nozzle 552 corresponding to the photovoltaic panel 2, allowing the chemical agent to flow from the nozzle.

[0091] A precise amount of 552 is sprayed onto the white panel. After the chemical agent is sprayed onto the surface of the white panel, it displays a color corresponding to the fault information of photovoltaic panel 2. When staff conduct inspections or maintenance, they can quickly locate the problem area simply by observing the markings on the surface of photovoltaic panel 2.

[0092] The marking mechanism 55, through its ingenious structural design and efficient connection, not only achieves rapid and accurate marking of problematic photovoltaic panels 2, but also greatly improves work efficiency and user experience, resulting in excellent performance.

[0093] In one embodiment of the present invention, such as Figure 4 As shown, the included angles between the dust thickness detection mechanism 52, the pressurized air blowing mechanism 53, the hot spot detection mechanism 54 and the marking mechanism 55 are 90 degrees, and the angle of a single rotation of the mounting roller 51 is 90 degrees.

[0094] Specifically, the installation positions and angles of the dust thickness detection mechanism 52, the pressurized air blowing mechanism 53, the hot spot detection mechanism 54, and the marking mechanism 55, as well as the single rotation angle of the mounting roller 51, are further defined. By defining the installation positions and angles of the mechanisms, not only is the space utilization between the mechanisms maximized, but the mounting roller 51 can also accurately drive the mechanism during rotation, ensuring that each mechanism can be accurately positioned within the predetermined working area, thereby guaranteeing the accuracy and consistency of the detection or processing operation. The single rotation angle of the mounting roller 51 is precisely set to 90 degrees, which perfectly matches the angle between the mechanisms, allowing the mounting roller 51 to accurately switch to the next mechanism each time it rotates. This precise angle control not only improves the automation level of the system, but also ensures the efficiency and stability of the entire detection and processing process. By precisely defining the installation positions, angles, and rotation angle of the mounting roller 51, the positional accuracy and performance of the system are significantly improved.

[0095] In one embodiment of the present invention, such as Figures 3-4 and Figure 9 As shown, a columnar support 511 and a support ring 4451 are respectively provided at positions corresponding to the surface of the mounting roller 51 and the surface of the movable slide 445. One end of the columnar support 511 is located on the support.

[0096] Inside the ring frame 4451, and slidably connected to the inner wall of the supporting ring frame 4451;

[0097] The cylindrical support 511 has, from the outside in, an annular inner ring 512, a first air inlet 513, and a mounting hole 514 arranged sequentially. An annular outer ring 4452 is fixedly connected to the outer end face of the support ring frame 4451 and is fitted onto the surface of the cylindrical support 511. The annular outer ring 4452 is located outside the annular inner ring 512 and is slidably connected to the surface of the annular inner ring 512. The annular outer ring 4452 is connected to the controller 42 via wires, and the annular inner ring 512 is connected to the dust thickness detection mechanism 52, the hot spot detection mechanism 54, and the marking mechanism 55 via wires. When the annular inner ring 512 is connected to the annular outer ring 512...

[0098] When ring 4452 is connected, dust thickness detection mechanism 52, hot spot detection mechanism 54 and marking mechanism 55 are powered on and operated. The outer end face of the annular energized outer ring 4452 is fixedly connected to an annular air inlet seat 4453. The annular air inlet seat 4453 is sleeved on the surface of the columnar support part 511 and located outside the first air inlet 513. One end of the annular air inlet seat 4453 is connected to the air supply pipe, and the annular air inlet seat 4453 is connected to the inside of the first air inlet 513.

[0099] The mounting roller 51 is internally divided into a central shaft cavity 100 and an arc-shaped cavity 200 by a partition. The central shaft cavity 100 houses a main air pipe 300, one end of which penetrates into the cylindrical support portion 511. An annular electrical inner ring 512 is fixedly connected to the surface of the end of the main air pipe 300 penetrating the cylindrical support portion 511. A second air inlet 400 is provided at the location corresponding to the first air inlet 513 on the surface of the end of the main air pipe 300 penetrating the cylindrical support portion 511. The second air inlet 400 is connected to both the first air inlet 513 and the interior of the main air pipe 300. Branches are evenly distributed on the inner wall of the arc-shaped cavity 200, corresponding to the location of the pressurized air blowing mechanism 53.

[0100] Pipe 500 and branch pipe 500 are respectively connected to the air knife 532 and the main air pipe 300. The inner wall of the arc-shaped cavity 200 corresponding to the position of the marking mechanism 55 is uniformly provided with branch head 700. The main air pipe 300 has multiple component injection pipes 600 inside. One end of the multiple component injection pipes 600 passes through the outside of the main air pipe 300 and is located inside the mounting hole 514. One end of the branch head 700 is connected to the nozzle 552, and the other end of the branch head 700 is connected to the inside of the branch injection pipe 600.

[0101] It should be noted that the end of the dispensing pipe 600 described in this embodiment located inside the mounting hole 514 is provided with a plug (not shown in the figure).

[0102] Specifically, to ensure the efficient and stable operation of the mounting roller 51 and the full functionality of each mechanism, we optimized the relevant components as follows: First, a cylindrical support 511 and a support ring frame 4451 were designed to effectively and stably limit and support the end of the mounting roller 51, significantly enhancing its stability during rotation. Second, an annular outer power-connecting ring 4452 and an annular inner power-connecting ring 512 were designed to ensure that the electrical equipment on each mechanism remains continuously and stably powered during the rotation of the mounting roller 51. This design not only improves the electrical performance of the system but also reduces the failure rate caused by poor contact. Furthermore, it also improves the air... The air path system has been optimized. The first air inlet 513, the annular air inlet seat 4453, the second air inlet 400, the main air pipe 300, and the branch pipe 500 are cleverly arranged and connected to form an efficient and stable air path system. This design ensures that the air injection operation of the air knife 532 is not affected when the mounting roller 51 rotates, thereby ensuring the stability and efficiency of the pressurized air blowing mechanism 53. Finally, there is an innovation in the chemical agent injection system. By setting the branch column head 700 and the branch injection pipe 600, we have achieved a flexible and efficient chemical agent injection method. This design allows users to inject different chemical agents into multiple sets of nozzles 552 according to actual needs, thereby meeting diverse treatment requirements. At the same time, this design also improves the system's flexibility and scalability, and has good performance.
