As the core part of photovoltaic power stations, the power generation efficiency and service life of photovoltaic modules are directly affected by the cleanliness of the module surface. The accumulation of pollutants such as dust and powder on the surface of photovoltaic modules will not only block the sunlight, reduce the amount of sunlight absorbed by photovoltaic modules, thereby reducing power generation, but also increase 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 service life of photovoltaic modules.

The angle self-switching mechanism 446 includes a protruding rod 4461, a spring 4462, a sliding tooth plate 4463, a driving gear 4464 and a one-way transmission 4465, wherein the protruding rod 4461 is slidably connected to a side surface of the movable slide 445 close to 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 44 5, and a spring 4462 is fixedly connected to the inner wall of the movable slide 445, a sliding tooth plate 4463 is fixedly connected to one end surface of the protruding rod 4461 penetrating into the inner wall of the movable slide 445, and is horizontally slidably connected to the inner wall of the movable slide 445, a driving gear 4464 is rotatably connected to the inner wall of the movable slide 445, and meshes with the sliding tooth plate 4463, and one end of the central axis of the driving gear 4464 is connected to one end of the central axis of the mounting roller 51 through a one-way transmission 4465.

[0037] It should be noted that the one-way transmission 4465 described in this embodiment is a ratchet one-way transmission.

[0038] 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 wind blowing mechanism 53, the hot spot detection mechanism 54 and the marking mechanism 55 can be automatically switched, which is simple to operate and has a good use effect.

[0039] During 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 toward the inner direction of the movable slide seat 445, and compresses the spring 4462. The movement of the protruding rod 4461 synchronously drives the sliding tooth plate 4463 to move, and drives the driving gear 4464 to rotate. Since a one-way transmission 4465 is provided between the driving gear 4464 and the central axis of the mounting roller 51, the mounting roller 51 does not rotate. When the protruding rod 4461 is separated from the surface of the lower end seat 442, the protruding rod 4461 and the sliding tooth plate 4463 are automatically reset under the influence of the elastic force of the spring 4462. The sliding tooth plate 4463 is reset and synchronously drives the driving gear 4464 to rotate in the opposite direction. The reverse rotation of the driving 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, and the use effect is good.

[0040] In one embodiment of the present invention, Figure 5As shown, the dust thickness detection mechanism 52 includes a first mounting socket 521, an electrical sensor 522 and an ultrasonic sensor 523, wherein the first mounting socket 521 is evenly clamped and fixed in a slot on the surface of the mounting roller 51 by an elastic clamp 1000, the electrical sensor 522 is evenly arranged on the surface of the first mounting socket 521, the ultrasonic sensor 523 is evenly arranged on the surface of the first mounting socket 521, and is located between two adjacent groups of electrical sensors 522, the electrical sensor 522 and the ultrasonic sensor 523 are both equipped with a wireless communication module, and the electrical sensor 522 and the ultrasonic sensor 523 are wirelessly connected to the controller 42 through the wireless communication module respectively to realize data transmission and reception of control instructions.

[0041] Specifically, the structure and connection relationship of the dust thickness detection mechanism 52 are further explained. The dust thickness detection mechanism 52 has a dual detection function, which can effectively detect dust and powder on the surface of the photovoltaic panel 2. The detection accuracy can be guaranteed through dual detection, and the use effect is good.

[0042] When in use, the installation roller 51 moves synchronously to drive the first installation bracket 521, the electrical sensor 522 and the ultrasonic sensor 523 to move. The electrical sensor 522 and the ultrasonic sensor 523 respectively detect dust and powder on the surface of the photovoltaic panel 2 during the movement. The electrical sensor 522 realizes measurement by measuring the change in conductivity of the dust. Dust will affect 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 through ultrasound. The principle is to use the propagation characteristics of ultrasound in the air. When encountering dust particles, scattering and reflection will occur. The sensor determines the thickness of the dust by receiving these signals.

[0043] In one embodiment of the present invention, Figure 3 and Figure 6 As shown, the pressurized wind blowing mechanism 53 includes a second mounting base 531, a wind knife 532, an air tank 533 and an air compressor 534, wherein the second mounting base 531 is evenly clamped and fixed in the groove on the surface of the mounting roller 51 by an elastic clamp 1000, the wind knife 532 is obliquely arranged on the surface of the second mounting base 531, the air tank 533 and the air compressor 534 are respectively arranged on the inner wall of the mounting frame 41 and are connected to each other, the air tank 533 is connected to the wind knife 532 through an air pipeline, a first solenoid valve is arranged on the air pipeline, and 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 reception of control instructions.

[0044] It should be noted that the gas tank 533 described in this embodiment includes a pressure detection mechanism (not shown in the figure), which is connected to the controller 42 through a bus system to realize data transmission and reception of control instructions. When the pressure detection mechanism detects that the gas inside the gas tank 533 is reduced, the data is sent to the controller 42, and the controller 42 controls the operation of the air compressor 534 to inflate the interior of the gas tank 533.

[0045] It should be noted that the surface of the mounting frame 41 described in this embodiment is provided with an air intake grille, and a dustproof net is provided inside the air intake grille.

[0046] Specifically, the structure and connection relationship of the pressurized wind blowing mechanism 53 are further explained. The pressurized wind blowing mechanism 53 is set to clean the surface of the photovoltaic panel 2 by pressurized wind blowing, which effectively replaces the traditional manual operation and water washing operation, reduces labor intensity, improves work efficiency, and has a good use effect.

[0047] When in use, the first solenoid valve receives a command to open, so that the compressed gas inside the gas tank 533 is injected into the wind knife 532 through the gas pipeline, and then blown to the surface of the photovoltaic panel 2 by the wind knife 532 to clean the dust and powder on the surface of the photovoltaic panel 2. When the pressure detection mechanism on the gas tank 533 detects that the gas inside the gas tank 533 is reduced, the data is sent to the controller 42, and the controller 42 controls the operation of the air compressor 534 to inflate the inside of the gas tank 533, and the use effect is good.

[0048] In one embodiment of the present invention, Figure 7 As shown, the hot spot detection mechanism 54 includes a third mounting seat 541 and a thermal imaging sensor 542, wherein the third mounting seat 541 is evenly clamped and fixed in a card slot on the surface of the mounting roller 51 by an elastic clamp 1000, and the thermal imaging sensor 542 is evenly arranged on the surface of the third mounting seat 541. The thermal imaging sensor 542 has a built-in wireless communication module, and the thermal imaging sensor 542 is connected to the controller 42 via the wireless communication module to realize data transmission and reception of control instructions.

[0049] 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, and it has the following functions: the first is hot spot detection. By capturing the thermal distribution image of the surface of the photovoltaic panel 2 by the thermal imaging sensor 542, the area with abnormal temperature, that is, the hot spot, can be intuitively found. The second is dust and powder detection: in addition to hot spot detection, the hot spot detection mechanism 54 can also determine whether there is dust, powder and other foreign matter on the surface of the photovoltaic panel 2 by analyzing the temperature distribution difference in the infrared thermal imaging image. The third is the cleaning effect judgment. After cleaning the dust, powder and other foreign 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. The hot spot detection mechanism 54 realizes comprehensive, efficient and accurate detection of the surface of the photovoltaic panel 2 through its precise structural design and connection relationship, as well as powerful thermal imaging detection function, and has a good use effect.

[0050] In one embodiment of the present invention, Figure 4 and Figure 8 As shown, the marking mechanism 55 includes a fourth mounting seat 551 and a nozzle 552, wherein the fourth mounting seat 551 is evenly clamped and fixed in a groove on the surface of the mounting roller 51 by an elastic clamp 1000, and the nozzle 552 is evenly arranged on the surface of the fourth mounting seat 551. The nozzle 552 includes a second solenoid valve, and the second solenoid valve is connected to the controller 42 through a built-in wireless communication module to realize data transmission and reception of control instructions.

[0051] It should be noted that 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 in number to the photovoltaic panels 2 , and their positions correspond.

[0052] It should be noted that white boards (not shown in the figure) are evenly arranged on the top of one side of the mounting plate frame 1 close to the lower end seat 442 described in this embodiment. The number of white boards is equal to that of the nozzles 552, and the positions are corresponding. By cleverly utilizing the characteristics of the white boards, they are used as intuitive indicators of chemical agent reactions. Specifically, the multiple groups of nozzles 552 are configured to spray their own unique chemicals onto these white boards. These chemicals are carefully selected and proportioned to ensure that each chemical can induce a specific color change after contacting the white boards. This color change is not only clearly identifiable, but also each chemical The colors caused by chemical agents are all unique, thus achieving intuitive identification and differentiation of chemical types. In this way, operators can quickly and accurately determine which chemicals have been applied to the whiteboard and their respective corresponding color changes. This not only improves work efficiency, but also greatly reduces the potential risks caused by misjudgment or confusion of chemicals. By cleverly combining the arrangement of the whiteboard and the nozzle 552, we provide users with an intuitive and easy-to-use identification system, which enables staff to quickly find faulty or unprocessed photovoltaic panels 2, and the use effect is good.

[0053] Specifically, the structure and connection relationship of the marking mechanism 55 are 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 photovoltaic panels with hot spots 2. This design is intended to help staff quickly and accurately locate problematic photovoltaic panels 2 during inspections or maintenance, thereby significantly improving work efficiency.

[0054] Specifically, the marking mechanism 55 is mainly composed of a nozzle 552, a reagent storage and supply pipeline, and an electromagnetic valve for accurately controlling the injection of the reagent. The nozzle 552 is carefully arranged on the fourth mounting seat 551 to ensure that they can cover all key areas on the photovoltaic panel 2. When the dust thickness detection mechanism 52 detects that the dust thickness parameter of the set area of ​​the photovoltaic panel 2 is high for multiple times, the controller 42 receives the data and determines that there are things on this photovoltaic panel 2 that are difficult to clean and need to be manually cleaned by the inspection personnel. In addition to sending information to the upper computer through the wireless communication module, it will also control the second electromagnetic valve on the nozzle 552 corresponding to the photovoltaic panel 2 to open, so that the chemical agent is quantitatively sprayed from the nozzle 552 to the whiteboard. After the whiteboard surface is sprayed with the chemical agent, it displays the color corresponding to the information to be cleaned. When the hot spot detection mechanism 54 detects the appearance of a hot spot on the photovoltaic panel 2, it can firstly determine that there is dust and powder on the photovoltaic panel 2, and know the corresponding area of ​​the dust and powder. Secondly, It is possible to determine whether the photovoltaic panel 2 is faulty by comparing the data detected by the dust thickness detection mechanism 52. If the data are consistent, it can be determined as dust or powder. If the data are inconsistent, it is determined to be a photovoltaic panel 2 fault. After the controller 42 determines that the photovoltaic panel 2 is faulty, in addition to sending information to the upper computer through the wireless communication module, it will also control the second solenoid valve on the nozzle 552 corresponding to the photovoltaic panel 2 to open, so that the chemical agent is sprayed quantitatively from the nozzle 552 to the whiteboard. After the whiteboard surface is sprayed with the chemical agent, the color corresponding to the fault information of the photovoltaic panel 2 is displayed. When the staff conducts inspections or maintenance, they only need to simply observe the marks on the surface of the photovoltaic panel 2 to quickly locate the problem area, thereby greatly saving the time for finding and solving the problem. The marking mechanism 55, through its exquisite structural design and efficient connection relationship, not only realizes the rapid and accurate marking of the problem photovoltaic panel 2, but also greatly improves the work efficiency and user experience, and the use effect is good.

[0055] In one embodiment of the present invention, Figure 4 As shown, the angles between the dust thickness detection mechanism 52, the pressurized wind blowing mechanism 53, the hot spot detection mechanism 54 and the marking mechanism 55 are 90 degrees respectively, and the angle of a single rotation of the mounting roller 51 is 90 degrees.

[0056] Specifically, the installation position, angle and single rotation angle of the dust thickness detection mechanism 52, pressurized air blowing mechanism 53, hot spot detection mechanism 54 and marking mechanism 55 are further limited. By limiting the installation position and angle of the mechanism, not only is the space utilization between the mechanisms maximized, but it is also convenient for the installation roller 51 to accurately drive the mechanism to operate during rotation, ensuring that each mechanism can be accurately positioned within a predetermined working area, thereby ensuring the accuracy and consistency of the detection or processing operation. The single rotation angle of the installation roller 51 is precisely set to 90 degrees, which perfectly matches the angle between the mechanisms, so that the installation roller 51 can 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 efficient and stable progress of the entire detection and processing process. By precisely limiting the installation position, angle and rotation angle of the installation roller 51, the position accuracy and use effect of the system are significantly improved.

When the annular power-connected inner ring 512 is connected to the annular power-connected outer ring 4452, the dust thickness detection mechanism 52, the hot spot detection mechanism 54 and the marking mechanism 55 are powered on and operated. The outer end surface of the annular power-connected outer ring 4452 is fixedly connected with an annular air inlet seat 4453, which is sleeved on the surface of the columnar support portion 511 and located outside the first air inlet 513.

The second air inlet 400 is respectively connected to the first air inlet 513 and the interior of the main air pipe 300. The inner wall of the arc cavity 200 corresponding to the position of the pressurized air blowing mechanism 53 is evenly provided with branch pipes 500, which are respectively connected to the wind knife 532 and the inside of the main air pipe 300; the inner wall of the arc cavity 200 corresponding to the position of the marking mechanism 55 is evenly provided with branch column heads 700; the main air pipe 300 has a multi-component injection pipe 600 built in; one end of the multi-component injection pipe 600 passes through the outside of the main air pipe 300 and is located inside the mounting hole 514; one end of the branch column head 700 is connected to the nozzle 552, and the other end of the branch column head 700 is connected to the inside of the branch injection pipe 600.

[0058] It should be noted that the dispensing tube 600 described in this embodiment is provided with a plugging cover (not shown in the figure) at one end located inside the mounting hole 514 .

Finally, the chemical injection system is innovative. By setting the sub-column head 700 and the sub-injection pipe 600, we have achieved a flexible and efficient chemical injection method. This design allows users to inject different chemicals into multiple groups of nozzles 552 according to actual needs, thereby meeting diverse processing needs. At the same time, this design also improves the flexibility and scalability of the system, and has a good use effect.
