[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0031] Most existing cleaning devices use water flow or scrapers to clean photovoltaic modules. When photovoltaic power stations are built in outdoor environments such as deserts and Gobi, it is difficult to obtain water resources, resulting in the photovoltaic power station being unable to obtain water flow to clean photovoltaic modules. Using scrapers to clean photovoltaic modules is easy to scratch the glass surface of photovoltaic modules, destroy the surface coating of photovoltaic modules, and further affect the light energy conversion rate of photovoltaic modules, reducing the practicality and reliability of the cleaning device. In view of the above problems, the utility model proposes a cleaning device 100.

[0032] See also Figures 1 to 7 In one embodiment of the utility model, the cleaning device 100 includes a fixed bracket 30 and a blowing device 10. The blowing device 10 is rotatably connected to the fixed bracket 30. The blowing device 10 is provided with a blowing port. The air outlet direction of the blowing port is configured to be set at an angle with the surface of the photovoltaic component 200. The blowing device 10 is used to clean the photovoltaic component 200.

[0033] It is understandable that during the operation of the photovoltaic power station, dust particles, fallen leaves and other debris in the environment accumulate on the photovoltaic modules 200, which will affect the efficiency of the photovoltaic modules 200 in absorbing and converting light energy. Therefore, construction workers usually need to regularly observe the dust conditions on the photovoltaic modules 200, or detect the dust conditions on the photovoltaic modules 200 by setting up a detection system. When the dust conditions reach a certain level, the cleaning device 100 is controlled to adopt a corresponding cleaning strategy, so that the photovoltaic modules 200 can operate in a relatively clean state to ensure the power conversion rate of the photovoltaic power station.

[0034] In the present application, the photovoltaic power station can feed back the results obtained by the detection system or the dust falling results input by the construction workers to the control system of the photovoltaic power station, so that the photovoltaic power station can feed back the cleaning signal to the user according to the corresponding program or control the cleaning device 100 to clean the photovoltaic components 200 in the photovoltaic power station to ensure the power conversion rate of the photovoltaic power station. The cleaning device 100 can be provided with a fixed bracket 30 on one side of the photovoltaic component 200, and the wind knife 13 can be installed and fixed by the fixed bracket 30, which can better improve the stability and reliability of the operation of the wind knife 13 and ensure the stable cleaning effect of the blowing device 10 on the photovoltaic component 200. The fixed bracket 30 can be installed on a photovoltaic bracket in a photovoltaic power station to support photovoltaic components. In this case, the fixed bracket 30 can be a seat plate or support rod 57 connected to the purlin installed on the photovoltaic bracket to support the photovoltaic components 200, so that the wind knife 13 can be better set up close to the photovoltaic components to improve the cleaning effect of the blowing device 10; or, the fixed bracket 30 can be erected at the construction location of the photovoltaic power station through structures such as columns and tripods, and set close to the photovoltaic components, so that the fixed bracket 30 can be set independently from the mounting bracket of the photovoltaic component 200, which is conducive to the independent disassembly and maintenance of the blowing device 10, and further improves the practicality and reliability of the blowing device 10. The blowing device 10 can generate airflow through a built-in fan or pump and blow it out from the blowing port; or a pipe can be used to connect the fan or pump so that the airflow enters the blowing device through the pipe and then blows out from the blowing port. In this case, an air inlet can be set on the blowing device 10 to connect the fan or pump through the pipe, or multiple air inlets can be set on the blowing device 10 and the pipes can be connected to the fan or pump to ensure a large air intake of the blowing device 10. By manually operating the fixed bracket 30 to rotate the blowing device 10 or using other rotating mechanisms to drive the blowing device 10 to rotate, the airflow outlet direction of the blowing port can be set at an angle with the surface of the photovoltaic module 200, and the angle between the blowing port and the photovoltaic module 200 can be better adjusted according to the size of the photovoltaic module 200, so that the airflow blowing out of the blowing port can better act on the surface of the entire photovoltaic module 200, ensuring that the airflow can more smoothly blow away foreign matter such as dust on the surface of the photovoltaic module 200, and better improve the cleaning effect of the cleaning device 100 on the photovoltaic module 200. Among them, the angle between the air outlet direction of the blowing port and the surface of the photovoltaic component can be set to 5°. At this angle, the blowing device 10 can direct the air flow from the side with a longer side length of the photovoltaic component to the surface of the entire photovoltaic component, thereby ensuring the cleaning effect of the blowing device 10 on the photovoltaic component.

[0035] By using the blowing device 10 to blow out an air curtain to clean the photovoltaic components, there is no need to lay drainage pipes at the construction site of the photovoltaic power station, which reduces the use of water resources, further reduces the difficulty of building the photovoltaic power station, and improves the operational convenience of the cleaning device 100; at the same time, it can avoid using scrapers to clean the photovoltaic components, which has a certain probability of scratching the surface coating of the photovoltaic components, thereby improving the cleaning reliability and stability of the cleaning device 100 on the photovoltaic components 200, and further improving the practicality of the cleaning device 100.

[0036] The technical solution of the utility model is to set a blowing device 10 on the cleaning device 100 to clean the photovoltaic module, and use the fixed bracket to rotate and adjust the blowing angle of the blowing device 10, so that the blowing device 10 can better apply the blowing airflow to the surface of the entire photovoltaic module 200 to achieve a better cleaning effect. It can effectively reduce the construction of cleaning water pipes in the photovoltaic power station and reduce the construction cost of the photovoltaic power station. At the same time, it can better prevent the photovoltaic modules from being scratched during the cleaning process, ensure the stability and reliability of the photovoltaic modules in absorbing and converting electrical energy, and then better improve the stability and reliability of the cleaning device 100 in cleaning the photovoltaic module 200, ensure the stable operation of the photovoltaic power station, and further improve the practicality and reliability of the cleaning device 100.

[0037] See also Figure 1 , Figure 3 and Figure 6 In an embodiment of the utility model, the blowing device 10 includes a flow supply mechanism 11 and a wind knife 13. The wind knife 13 is rotatably connected to a fixed bracket. The wind knife 13 is provided with a blowing port. The flow supply mechanism 11 is provided with a flow supply pipeline 111. The flow supply pipeline 111 is connected to the wind knife 13.

[0038] In this embodiment, the blowing device 10 may include a flow supply mechanism 11 and a wind knife 13. The wind knife 13 may be mounted and fixed on the fixed bracket 10, and the wind knife 13 may rotate relative to the fixed bracket 10 to adjust the blowing angle of the blowing port. The flow supply mechanism 11 may be a device that can generate a certain pressure airflow, such as a fan, an air compressor pump, etc. By connecting the flow supply mechanism 11 and the wind knife 13 with a flow supply pipeline 111, the airflow generated by the flow supply mechanism 11 may enter the air duct in the wind knife 13 through the flow supply pipeline 111, and then blow out from the blowing port of the wind knife 13 to act on the photovoltaic module 200, thereby achieving a cleaning effect on the photovoltaic module. Among them, the blowing port of the wind knife 13 may be one or more narrow strip-shaped holes opened on the side of the wind knife 13, so that the airflow blown out from the blowing port can maintain a high wind speed and flow rate, thereby better improving the cleaning effect of the blowing device 10 on the photovoltaic module 200.

[0039] In addition, the wind knife 13 can configure the length of the blowing port to be greater than or equal to the long side length or wide side length of the photovoltaic component, so that the wind knife 13 can blow air on one side of the photovoltaic component 200 to apply the airflow to the entire photovoltaic component 200, which is conducive to better simplifying the overall structural setting of the blowing device 10 and further improving the practicality and reliability of the cleaning device 100.

[0040] See also Figure 1 , Figure 3 and Figure 6 In an embodiment of the utility model, the wind knife 13 is provided with at least two air inlets, and the flow supply pipeline 111 is provided with at least two branch pipes, each branch pipe being connected to an air inlet.

[0041] In this embodiment, the use of a long air outlet requires a large amount of air flow to be introduced into the wind knife 13 to ensure uniform and stable air outlet. Therefore, at least two air inlets can be provided on the wind knife 13, and the flow supply mechanism 11 can be provided with at least two branch pipes on the flow supply pipeline 111, so that one branch pipe is connected to one air inlet. The air intake volume of the wind knife 13 can be better increased under the action of the coordinated air intake of multiple branch pipes, so that the blowing airflow blown out from the blowing port can act on the surface of the entire photovoltaic module 200 more stably and evenly, further improving the cleaning effect of the cleaning device 100.

[0042] See also Figure 3 and Figure 4 In an embodiment of the present utility model, the fixed bracket 30 includes a supporting frame 31 and a fixing frame 33 . The fixing frame 33 is connected to the wind knife 13 , and the fixing frame 33 is rotatably connected to the supporting frame 31 .

[0043] In this embodiment, the fixed bracket 30 may include a support frame 31 and a fixed frame 33, which may be structural arrangements of a seat plate, a support column, etc. The support frame 31 may be installed on the purlins of the photovoltaic bracket, or the support frame 31 may be erected at the construction location of the photovoltaic power station using structures such as columns and tripods. By connecting the fixed frame 33 to the wind knife 13 and connecting the support frame 31 and the fixed frame 33 using connecting parts such as a rotating shaft or bolts, the fixed frame 33 may be made to rotate with a connecting part such as a rotating shaft or bolts as the central axis, so that the fixed frame 33 may drive the wind knife 13 to rotate on the support frame 31. Furthermore, the angle between the air outlet direction of the air outlet and the surface of the photovoltaic module 200 can be changed by rotating the fixing frame 33, so that the user can adjust the blowing angle of the wind knife 13 according to the size of the photovoltaic module 200 when assembling the blowing device 10, thereby ensuring that the blowing device 10 can stably clean the photovoltaic module as a whole; or other mechanisms can be used to drive the wind knife 13 to rotate, so that the wind knife 13 can better apply the outlet airflow to the surface of the entire photovoltaic module 200, thereby further improving the practicality and reliability of the cleaning device 100.

[0044] See also Figures 3 to 5 In an embodiment of the present utility model, the fixed bracket 30 further includes a rotating mechanism 35 , and the rotating mechanism 35 is connected to the wind knife 13 and drives the wind knife 13 to rotate.

[0045] In this embodiment, the wind knife 13 is rotatably arranged by utilizing the rotation connection between the support frame 31 and the fixed frame 33, and the fixed frame 30 can also be provided with a swing push rod, a swing connecting rod, a motor and other rotating mechanisms 35 acting on the wind knife 13, so that the wind knife 13 can be directly driven to rotate under the action of the rotating mechanism 35, or the wind knife 13 can be indirectly driven to rotate through the linkage structure, so that the blowing device 10 can achieve the swing effect of the wind knife 13, which is conducive to better applying the airflow blown by the blowing device 10 to the entire photovoltaic module 200, ensuring the stable and reliable cleaning of the photovoltaic module 200 by the blowing device 10, and further improving the practicality and reliability of the cleaning device. Among them, the cleaning device 100 can realize the automatic cleaning effect of the blowing device 10 by regulating the rotating mechanism 35 and the flow supply mechanism 11, which is conducive to better improving the automatic control of the cleaning device, reducing the manual maintenance workload of the photovoltaic power station, and further improving the convenience of operation of the photovoltaic power station.

[0046] See also Figure 5 In an embodiment of the utility model, a driven gear 131 is provided on one side of the wind knife 13, and the rotating mechanism 35 includes a rotating motor 351 and a driving gear 353, the driving gear 353 is meshed and connected with the driven gear 131, and the rotating motor 351 drives the driving gear 353 to rotate, so that the driving gear 353 drives the driven gear 131 and the wind knife 13 to rotate.

[0047] In this embodiment, the rotating mechanism 35 can install the rotating motor 351 on the purlin of the photovoltaic bracket, or the rotating motor 351 can be set up on one side of the wind knife 13 through other bracket structures, and the driving gear 353 can be driven to rotate by the transmission motor, so that the driving gear 353 can be meshed and transmitted to the driven gear 131. At this time, the driven gear 131 is fixedly installed on one side of the wind knife 13, so that the driven gear 131 can be driven by the rotational force of the driving gear 353 to drive the wind knife 13 to rotate, thereby realizing the rotation and swinging of the wind knife 13, which is conducive to better realizing the automatic cleaning of the blowing device 10 under the action of the rotating motor 351, ensuring the stable cleaning effect of the blowing device 10 on the photovoltaic component 200, and further improving the practicality and reliability of the cleaning device 100.

[0049] In this embodiment, the cleaning device 100 can be installed with a moving mechanism 50 on a photovoltaic bracket that supports the photovoltaic assembly 200, and the moving mechanism 50 can be arranged close to the photovoltaic assembly; or the moving mechanism 50 can be installed on a supporting structure such as a pillar or a tripod at the construction location of the photovoltaic power station. At this time, the front-to-back direction perpendicular to the arrangement direction of the photovoltaic assembly 200 can be defined as the first direction, and the moving mechanism 50 can be a slide rail sliding mechanism or a transmission belt mechanism, etc. By installing and connecting the fixed bracket 30 on the moving mechanism 50, and extending the wind knife 13 along the arrangement direction of the photovoltaic assembly 200, the moving mechanism 50 can be used to drive the fixed bracket 30 and the wind knife 13 to move along the first direction, so that the wind knife 13 can better act on the airflow on the entire photovoltaic assembly 200 during the movement process, which is conducive to better ensuring the overall cleaning of the photovoltaic assembly 200 by the blowing device 10 when the overall size of the photovoltaic assembly 200 is large, and further improving the practicality and reliability of the detection system 100. Among them, by utilizing the rotatable setting of the fixed bracket 30 and the wind knife 13, the angle between the wind knife 13 and the photovoltaic component 200 can be adjusted by rotating the wind knife 13, so that the blowing airflow can act on the surface of the photovoltaic component 200 at a more suitable wind entry angle, and under the action of the moving mechanism 50 driving the fixed bracket 30 and the wind knife 13 to move along the first direction, it is beneficial to better improve the cleaning effect of the blowing device 100 on the photovoltaic component 200, and it is beneficial to reduce the output power of the flow supply mechanism 11.

The driving motor 51 drives the driving wheel group 53 and the transmission belt 55 to rotate, so that the transmission belt 55 drives the fixed bracket 30 and the wind knife 13 to move along the first direction.

[0051] In this embodiment, by using a transmission belt 55 to sleeve a driving wheel group 53 composed of at least two rotating wheels, the driving motor 51 can be used to drive the driving wheel group 53 to rotate, so that the driving belt 55 can be driven to rotate under the action of the rotation of the driving wheel group 53. At this time, by connecting the fixed bracket 30 to the transmission belt 55, the fixed bracket 30 and the wind knife 13 can be driven to move along the first direction during the rotation of the transmission belt 55, so that the mobile mechanism 50 can stably drive the wind knife 13 to move and clean the photovoltaic component 200, further improving the structural stability and reliability of the cleaning device. By using a mobile mechanism 50 driven by a transmission belt 55, the transmission belt 55 can be used to lift the wind knife 13 to a position with a certain distance from the surface of the photovoltaic component 200, effectively avoiding the wind knife 13 from contacting the photovoltaic component 200 during the moving cleaning process and having a certain probability of scratching the surface of the photovoltaic component, further improving the practicality and reliability of the cleaning device 100. In addition, using the transmission belt 55 to drive the wind knife 13 to move is also beneficial to better improve the smoothness of the movement of the wind knife 13, reduce the shaking of the wind knife 13 during the cleaning process, and further improve the structural stability and reliability of the cleaning device 100.
