[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The following description, with reference to the accompanying drawings, describes an automatic coating device 100 for self-cleaning film of photovoltaic modules according to an embodiment of the present invention.

[0024] like Figure 1-2 As shown, the photovoltaic module self-cleaning film automatic coating equipment 100 according to an embodiment of the present utility model includes a mounting frame 1, a walking component (not shown in the figure), a spraying component 3 and a blowing component 4.

[0025] Mounting bracket 1 is suitable for mounting on photovoltaic panel 2. Specifically, as shown in the figure... Figure 1 As shown, the mounting frame 1 serves as the basic support structure for the entire device and is a rectangular frame to ensure that the mounting frame 1 can be stably set on the photovoltaic panel 2, providing a stable platform for the subsequent spraying assembly 3 and blowing assembly 4.

[0026] The walking component is mounted on the mounting frame 1 and is positioned relative to the mounting frame 1 along the length of the mounting frame 1 (e.g., Figure 1 (As shown in the forward and backward directions) is movable. Specifically, as... Figure 1 As shown, the walking device is mounted on the mounting frame 1 and can move along the front and back direction on the mounting frame 1 by means of motor drive, lead screw drive, etc.

[0027] The spraying assembly 3 is mounted on the traveling assembly and located on the side of the traveling assembly facing the photovoltaic panel 2. The spraying assembly 3 includes a roller 31 and a first nozzle 32. The first nozzle 32 is mounted on the roller 31 so that the first nozzle 32 sprays a cleaning film liquid onto the roller 31. The roller 31 is located on the side of the traveling assembly facing the photovoltaic panel 2 and can rotate relative to the traveling assembly in the width direction of the traveling assembly (e.g., ...). Figure 1 The panel (shown in the left-right direction) can be rotated to apply a cleaning film to the photovoltaic panel 2. Specifically, as shown... Figure 1 and Figure 2 As shown, the roller 31 extends in the left-right direction and is rotatably disposed below the traveling assembly. The first nozzle 32 is disposed on the traveling assembly and is located above and directly opposite the roller 31, so that the cleaning film liquid can be sprayed onto the roller 31. When the traveling assembly drives the spraying assembly 3 to move in the front-back direction, the roller 31 can evenly apply the cleaning film liquid to the surface of the photovoltaic panel 2.

[0028] A blower assembly 4 is mounted on the traveling assembly. The blower assembly 4 is used to blow away dust from the photovoltaic panel 2, and / or to dry the cleaning film liquid on the photovoltaic panel 2. Specifically, as... Figure 1 and Figure 2 As shown, the blowing assembly 4 is located below the walking assembly, so that the walking assembly drives the blowing assembly 4 to move. The blowing assembly 4 blows away the dust on the photovoltaic panel 2 and dries the cleaning film liquid on the photovoltaic panel 2, thereby helping to maintain the cleanliness of the photovoltaic panel 2 and ensuring that the cleaning film liquid can dry quickly, thereby improving the efficiency and quality of the roller coating operation.

[0029] The photovoltaic module self-cleaning film automatic coating equipment 100 of this utility model embodiment is equipped with a mounting frame 1, a walking component, a spraying component 3, and a blowing component 4. The walking component and the spraying component 3 spray the photovoltaic panel 2, and the blowing component 4 not only cleans the dust on the photovoltaic panel 2, but also accelerates the drying of the cleaning film liquid, prevents secondary damage to the cleaning film liquid, reduces the labor intensity of manual labor, improves the construction quality and speed, saves raw materials, and has good economic and environmental benefits.

[0030] In some embodiments, such as Figure 1As shown, the mounting frame 1 includes a first horizontal plate 11, a second horizontal plate 12, a first connecting plate 13, and a second connecting plate 14. The first horizontal plate 11 and the second horizontal plate 12 extend in the front-to-back direction and are spaced apart from each other in the left-to-right direction. The first connecting plate 13 and the second connecting plate 14 extend in the left-to-right direction and are spaced apart in the front-to-back direction. The rear ends of the first horizontal plate 11 and the second horizontal plate 12 are respectively connected to the left and right ends of the first connecting plate 13. The front ends of the first horizontal plate 11 and the second horizontal plate 12 are respectively connected to the left and right ends of the second connecting plate 14. Thus, the mounting frame 1 is generally frame-shaped.

[0031] In some embodiments, the automatic coating equipment 100 for self-cleaning photovoltaic modules further includes a first traveling wheel 15 and a second traveling wheel 16. The first traveling wheel 15 and the second traveling wheel 16 are rotatably disposed at both ends of the mounting frame 1 and are spaced apart from each other along the length of the mounting frame 1. The first traveling wheel 15 and the second traveling wheel 16 are respectively adapted to be disposed at both ends of the photovoltaic panel 2, so that the first traveling wheel 15 and the second traveling wheel 16 drive the mounting frame 1 to move on the photovoltaic panel 2. Specifically, as shown in the figure... Figure 1 and Figure 2 As shown, there are two first traveling wheels 15 and two second traveling wheels 16. The first traveling wheel 15 is located on the rear side of the mounting frame 1 (i.e., the first traveling wheel 15 is located on the first connecting plate 13 of the mounting frame 1), and the second traveling wheel 16 is located on the front side of the mounting frame 1 (i.e., the second traveling wheel 16 is located on the second connecting plate 14 of the mounting frame 1). The first traveling wheel 15 and the second traveling wheel 16 are arranged opposite each other in the front-rear direction. When the mounting frame 1 is placed on the photovoltaic panel 2, the first traveling wheel 15 is located on the rear end face of the photovoltaic panel 2 and can rotate on the rear end face of the photovoltaic panel 2. The second traveling wheel 16 is located on the front end face of the photovoltaic panel 2 and can rotate on the front end face of the photovoltaic panel 2. Thus, the first traveling wheel 15 and the second traveling wheel 16 can drive the mounting frame 1 to move in the left-right direction on the photovoltaic panel 2.

[0032] In some embodiments, the photovoltaic module self-cleaning film automatic coating equipment 100 further includes a first driving member (not shown in the figure). The first driving member is connected to one of the first traveling wheel 15 and the second traveling wheel 16, so that the first driving member drives the first traveling wheel 15 and the second traveling wheel 16 to rotate. Specifically, the first driving member can be a drive motor and is mounted on the mounting bracket 1. The output shaft of the first driving member is connected to the first traveling wheel 15, thereby driving the first traveling wheel 15 to rotate. By adjusting the rotation speed of the first driving member, the forward speed, backward speed, and other actions of the device can be precisely controlled.

[0033] In some embodiments, the walking assembly includes a housing, a first wheel, and a second wheel.

[0034] The housing is mounted on the mounting bracket 1, and both the spraying assembly 3 and the blowing assembly 4 are housed inside the housing. Specifically, the roller 31 is rotatably mounted at the lower end of the housing, and the blowing assembly 4 and the first nozzle 32 are both located at the lower end of the housing. Thus, the housing protects the spraying and blowing assemblies from external environmental interference, provides necessary structural support for the spraying assembly 3 and the blowing assembly 4, and makes the walking assembly setup more reasonable.

[0035] The first and second wheels are rotatably mounted on the housing and spaced apart vertically. The mounting frame 1 is clamped between the first and second wheels to allow them to move on the mounting frame 1. Specifically, the first and second wheels are rotatably mounted inside the housing and spaced apart vertically. When the walking assembly is mounted on the mounting frame 1, the first wheel can be located at the upper end of the first horizontal plate 11 or the upper end of the second horizontal plate 12 of the mounting frame 1, and the second wheel can be located at the lower end of the first horizontal plate 11 or the lower end of the second horizontal plate 12 of the mounting frame 1. This allows the first horizontal plate 11 or the second horizontal plate 12 of the mounting frame 1 to be clamped between the first and second wheels, enabling the first and second wheels to move on the mounting frame 1 and ensuring the stability of the walking assembly.

[0036] In some embodiments, the photovoltaic module self-cleaning film automatic coating device 100 further includes a second driving member (not shown in the figure). The second driving member is disposed on the housing and connected to at least one of the first wheel and the second wheel, so that the second driving member drives the first wheel and the second wheel to rotate. Specifically, the second driving member can be a drive motor, and the second driving member is disposed on the housing and connected to the first wheel or the second wheel, thereby driving the first wheel or the second wheel to rotate, causing the walking component to move in the back-and-forth direction.

[0037] In some embodiments, the blower assembly 4 includes a first blower assembly 41 and a second blower assembly 42, the first blower assembly 41 and the second blower assembly 42 are disposed on the walking assembly and the first blower assembly 41 and the second blower assembly 42 are along the length direction of the walking assembly (e.g., Figure 1 The rollers (as shown in the front-to-back direction) are spaced apart and positioned relative to each other. The roller 31 is located between the first blowing assembly 41 and the second blowing assembly 42. The first blowing assembly 41 is used to blow away dust from the photovoltaic panel 2, and the second blowing assembly 42 is used to dry the cleaning film liquid on the photovoltaic panel 2. Specifically, as shown in the figure... Figure 1 and Figure 2As shown, the first blowing assembly 41 and the second blowing assembly 42 are both located below the housing of the walking assembly. The first blowing assembly 41 is located in front of the roller 31 and extends downward and is inclined toward the side away from the roller 31 (in other words, the first blowing assembly 41 extends downward and is inclined forward), so that the first blowing assembly 41 blows the photovoltaic panel 2 in front of the roller 31 to clean the dust on the photovoltaic panel 2. The second blowing assembly 42 is located behind the roller 31 and extends downward and is arranged downward (in other words, the second blowing assembly 42 extends downward and is arranged directly opposite the photovoltaic panel 2), so that the second blowing assembly 42 blows the photovoltaic panel 2, which is coated with cleaning film liquid, behind the roller 31 to dry the cleaning film liquid on the photovoltaic panel 2.

[0038] In some embodiments, the blowing assembly 4 includes an air compressor 43, a first delivery pipe, and a second nozzle.

[0039] Air compressor 43 is adapted to generate compressed air. The two ends of the first delivery pipe are respectively connected to air compressor 43 and second nozzle. The second nozzle is located on the traveling assembly and adjacent to roller 31 so that compressed air is delivered to photovoltaic panel 2 through the second nozzle to dry the cleaning film liquid on photovoltaic panel 2, or to blow away dust from photovoltaic panel 2. Specifically, air compressor 43 is located on one side of photovoltaic panel 2 and is connected to the second nozzle through the first delivery pipe. There are multiple second nozzles, which are arranged in two rows along the left and right direction. One row is located behind roller 31 and extends downwards to dry the cleaning film liquid on photovoltaic panel 2. The other row is located in front of roller 31 and is inclined to the side away from roller 31 to blow and clean photovoltaic panel 2.

[0040] It should be understood that the second nozzle can also be a nozzle with a strip-shaped air outlet extending in the left and right direction.

[0041] In some embodiments, the automatic coating equipment 100 for self-cleaning photovoltaic modules further includes a storage tank 6 and a pump 5. The storage tank 6 is located on one side of the photovoltaic panel 2 and is suitable for storing cleaning film liquid. The pump 5 is connected to both the storage tank 6 and the first nozzle 32, so that the cleaning film liquid can be transported to the first nozzle 32 via the pump 5. Specifically, as Figure 1 As shown, the storage tank 6 is located on one side of the photovoltaic panel 2 and contains cleaning film liquid. The pump 5 can be located outside the storage tank 6 and connected to the storage tank 6 and the first nozzle 32 through the second delivery pipe, so that the cleaning film liquid in the storage tank 6 flows into the first nozzle 32 through the pump 5.

[0042] In some embodiments, the photovoltaic module self-cleaning film automatic coating equipment 100 further includes a third driving member (not shown in the figure), which is connected to the roller 31 so that the third driving member drives the roller 31 to rotate. Specifically, the third driving member is a drive motor, which is mounted on the housing and connected to the roller 31, thereby driving the roller 31 to rotate on the photovoltaic panel 2 to apply cleaning film liquid to the photovoltaic panel 2.

[0043] In some embodiments, the photovoltaic module self-cleaning film automatic coating equipment 100 further includes a power distribution device, an integrated control box, and a power supply. The power supply is connected to the first drive unit, the second drive unit, the third drive unit, the pump 5, and the air compressor 43 through the power distribution device and the integrated control box, respectively, thereby supplying power to the pump 5 and the air compressor 43 and controlling the operation of the first drive unit, the second drive unit, the third drive unit, the pump 5, and the air compressor 43. The storage box 6, the pump 5, the air compressor 43, the power distribution device, the integrated control box, and the power supply are integrated on the same frame, so that these components are compactly installed together to form a highly integrated roller coating device.

[0044] In some embodiments, the photovoltaic device includes a photovoltaic module and a photovoltaic module self-cleaning film automatic coating device 100.

Thus, the photovoltaic module self-cleaning film automatic coating equipment 100 sprays cleaning film liquid onto the photovoltaic panel 2.

[0046] The photovoltaic device of this utility model has the advantages of high power generation efficiency and low cost.

[0047] The photovoltaic module self-cleaning film automatic coating equipment 100 of this utility model embodiment utilizes a combination of a walking component, a spraying component 3, and a blowing component 4 to implement the coating process on the glass surface of photovoltaic modules.
