[0037] Please refer to Figure 1-Figure 5 This embodiment provides a photovoltaic system, which includes a plurality of photovoltaic panels 200 and at least one photovoltaic panel cleaning mechanism 100; the photovoltaic panel cleaning mechanism 100 is used to clean one or more of the plurality of photovoltaic panels 200.

[0038] The photovoltaic panel cleaning mechanism 100 is used to clean one or more photovoltaic cells. Based on this, this embodiment is described based on the example of the photovoltaic panel cleaning mechanism 100 cleaning one of the photovoltaic panels 200.

[0039] Specifically, when configuring the photovoltaic panel cleaning mechanism 100 , the photovoltaic panel cleaning mechanism 100 may include a rolling track 110 , a conductive component 120 , a driving component 130 , and a cleaning component 140 ;

[0040] The rolling track 110 is arranged on the side of the photovoltaic panel 200 and is arranged along the extension direction of the photovoltaic panel 200; the driving component 130 is connected to the cleaning component 140, and the driving component 130 and the rolling track 110 can be rolled together; the conductive component 120 is electrically connected to the discharge module of the photovoltaic panel 200 and the driving component 130;

[0041] The driving assembly 130 is used to roll along the rolling track 110 , thereby driving the cleaning assembly 140 to move relative to the photovoltaic panel 200 , thereby cleaning the photovoltaic panel 200 .

[0042] With such a setting, during the cleaning process, the driving assembly 130 can move relative to the photovoltaic panel 200, thereby driving the cleaning assembly 140 to move relative to the surface of the photovoltaic panel 200, thereby cleaning the surface of the photovoltaic panel 200. With such a setting, the manual cleaning method of the photovoltaic panel 200 in the prior art can be replaced, thereby reducing the manual cleaning workload of the photovoltaic panel 200, thereby improving the cleaning efficiency of the photovoltaic panel 200, reducing the cleaning and maintenance costs of the photovoltaic panel 200, and thereby reducing the operating costs of the solar power plant;

[0043] Moreover, when the above-mentioned structural setting is adopted, since the conductive component 120 is electrically connected to the discharge module of the photovoltaic panel 200 and the driving component 130, the driving component 130 can use the electric energy generated by the photovoltaic panel 200 to operate during the movement of the driving component 130, so that the energy supply structure of the driving component 130 is optimized through such a setting, thereby simplifying the structure of the photovoltaic panel cleaning mechanism 100, facilitating the long-term operation of the photovoltaic panel cleaning mechanism 100, and thus reducing its operating cost;

[0044] In addition, the photovoltaic panel cleaning mechanism 100 adopts a method of configuring the rolling track 110 on the side of the photovoltaic panel 200 and setting it along the extension direction of the photovoltaic panel 200, and the driving component 130 and the rolling track 110 can be rolled together; thereby, the position and length of the rolling track 110 can be adjusted to make its extension direction consistent with the extension direction of the photovoltaic panel 200, and then multiple photovoltaic panels 200 can be set in the same way, and the position and length of the rolling track 110 can be adaptively adjusted, so that the driving component 130 can roll along the rolling track 110 to clean multiple photovoltaic panels 200, that is, the structural length of the rolling track 110 can be adjusted to adapt to the cleaning needs of photovoltaic panels 200 of different lengths or multiple photovoltaic panels 200, so that through such a setting method, the cleaning efficiency can be improved and the installation and use cost of the photovoltaic panel cleaning mechanism 100 can be reduced.

[0045] For further information, please refer to Figure 1-Figure 5 In this embodiment, when configuring the slide rail, the rolling rail 110 includes a first rail slide groove 111 and a second rail slide groove 112, and the first rail slide groove 111 and the second rail slide groove 112 are distributed on opposite sides of the photovoltaic panel 200;

[0046] The driving assembly 130 includes a driving motor 131, a first driving wheel 132 and a second driving wheel 133. The first driving wheel 132 and the second driving wheel 133 are both drivingly connected to the driving motor 131, and the first driving wheel 132 and the second driving wheel 133 are rollingly matched with the first rail groove 111 and the second rail groove 112 respectively.

[0047] Through such a setting, the driving component 130 can roll with the first rail groove 111 and the second rail groove 112 respectively through the first driving wheel 132 and the second driving wheel 133, thereby improving the stability of its movement. In addition, such a setting is also conducive to the setting of the cleaning component 140, so that the cleaning component 140 can be installed across the photovoltaic panel 200, so as to clean the photovoltaic panel 200 between the first rail groove 111 and the second rail groove 112.

[0048] As can be seen from the above content, in this embodiment, the driving component 130 is electrically connected to the discharge module of the photovoltaic panel 200 through the conductive component 120, so that the driving component 130 can use the electric energy converted by the photovoltaic panel 200 as the driving electric energy during operation. Based on this, when configuring the conductive component 120, the conductive component 120 includes a first conductive strip 121, a second conductive strip 122, a first conductive ring 123 and a second conductive ring 124;

[0049] The first conductive strip 121 and the second conductive strip 122 are respectively disposed in the first rail slot 111 and the second rail slot 112, and the first conductive strip 121 and the second conductive strip 122 are respectively electrically connected to the positive electrode and the negative electrode of the discharge module of the photovoltaic cell panel 200; the first conductive ring 123 and the second conductive ring 124 are respectively connected to the first driving wheel 132 and the second driving wheel 133;

[0050] The first conductive ring 123 is used to rotate synchronously with the first driving wheel 132 to be electrically connected to the first conductive strip 121 , and the second conductive ring 124 is used to rotate synchronously with the second driving wheel 133 to be electrically connected to the second conductive strip 122 .

[0051] The purpose of such a setting is to enable the driving component 130 to maintain an electrical connection with the discharge module of the photovoltaic panel 200 while rolling along the rolling track 110, that is, to enable the discharge module of the photovoltaic panel 200 to maintain a state of continuously supplying power to the driving component 130, thereby avoiding the risk of power outage and shutdown.

[0052] Based on the above structure, please refer to Figure 1-Figure 5When configuring the first rail chute 111 and the second rail chute 112 of the rolling rail 110, since it takes into account the rolling cooperation with the first driving wheel 132 and the second driving wheel 133, and the function of installing the first conductive strip 121 and the second conductive strip 122, in order to avoid leakage, the bottom of the first rail chute 111 is configured with a first insulating layer 115, and the bottom of the second rail chute 112 is configured with a second insulating layer 116, the first driving wheel 132 is in rolling contact with the first insulating layer 115, and the second driving wheel 133 is in rolling contact with the second insulating layer 116, that is, by the provision of the first insulating layer 115 and the second insulating layer 116, it is avoided that the electric energy is lost by the first rail chute 111 and the second rail chute 112;

[0053] At the same time, the bottom of the first rail slide groove 111 is configured with a first conductive groove 113 along its extension direction, and the bottom of the second rail slide groove 112 is configured with a second conductive groove 114 along its extension direction. The first conductive bar 121 and the second conductive bar 122 are respectively arranged in the first conductive groove 113 and the second conductive groove 114; in this way, the first conductive bar 121 and the second conductive bar 122 are positioned and installed to avoid the first driving wheel 132 and the second driving wheel 133 from slipping with the first conductive bar 121 and the second conductive bar 122.

[0054] For further information, please refer to Figure 1-Figure 5 As can be seen from the above content, the present embodiment adopts the method of setting the aforementioned first conductive strip 121, the second conductive strip 122, the first conductive ring 123 and the second conductive ring 124, so that the driving component 130 is electrically connected to the first conductive strip 121 through the first conductive ring 123, and the second conductive ring 124 is electrically connected to the second conductive strip 122 during the movement, so as to conduct electricity. Based on this, in order to enable the driving motor 131 to be electrically connected to the rotating first conductive ring 123 and the second conductive ring 124 during the rotation of the first driving wheel 132 and the second driving wheel 133, the conductive component 120 further includes a first wire 125, a first carbon brush 126, a second wire 127 and a second carbon brush 128;

[0055] The first carbon brush 126 is in rolling contact with the first conductive ring 123 and is electrically connected to the drive motor 131 through the first conductive wire 125 ; the second carbon brush 128 is in rolling contact with the second conductive ring 124 and is electrically connected to the drive motor 131 through the second conductive wire 127 .

[0056] Therefore, by such a configuration, the driving motor 131 can be continuously kept electrically connected to the discharge module of the photovoltaic panel 200 .

[0057] In addition, in order to improve the use range of the photovoltaic panel cleaning mechanism 100 during use, avoid the sudden failure of the driving motor 131 and the photovoltaic panel 200 to disconnect and cause the photovoltaic panel cleaning mechanism 100 to stop, and extend its endurance, the photovoltaic panel cleaning mechanism 100 also includes a power storage module 150, which is electrically connected to the conductive component 120 and the driving motor 131. Through such a setting, the power storage module 150 can store electric energy, so that when the photovoltaic panel 200 generates insufficient power or the conductive component 120 temporarily fails, the power in the power storage module 150 can be used to supply the driving motor 131 to operate, so that the photovoltaic panel cleaning mechanism 100 can clean the photovoltaic panel 200 when the photovoltaic panel 200 generates insufficient power or the conductive component 120 temporarily fails; in addition, such a setting can simplify the structure of the first conductive strip 121 and the second conductive strip 122, so that the length of the first conductive strip 121 and the second conductive strip 122 can be less than the length of the first rail chute 111 and the second rail chute 112.

[0058] For further information, please refer to Figure 1-Figure 5 On the basis of the above structure, when configuring the cleaning assembly 140, the cleaning assembly 140 includes a main board 141 and a cleaning brush body 142. The cleaning brush body 142 is connected to the main board 141 and is located on the side of the main board 141 facing the photovoltaic cell panel 200. The driving motor 131 and the power storage module 150 are both connected to the main board 141. In order to prevent external dust and debris from entering the driving assembly 130 and the cleaning assembly 140, the photovoltaic cell panel cleaning mechanism 100 also includes a cover plate 160, which spans the photovoltaic cell panel 200 and covers the driving assembly 130 and the cleaning assembly 140.

[0059] Based on the above, it is also necessary to explain that please refer to Figure 1-Figure 5 In this embodiment, when configuring the rolling track 110, the first track slot 111 and the second track slot 112 can be made of channel steel and distributed on both sides of the photovoltaic cell panel 200, and a layer of insulating resin is covered in the channel steel, so that the first track slot 111 and the second track slot 112 form a first insulating layer 115 and a second insulating layer 116 respectively, and then the first conductive strip 121 and the second conductive strip 122 are installed on the first insulating layer 115 and the second insulating layer 116, so that the first conductive strip 121 and the second conductive strip 122 are insulated from the first track slot 111 and the second track slot 112 made of channel steel; and the first conductive strip 121 and the second conductive strip 122 in the channel steel on both sides are respectively connected to the positive pole of the power output terminal and the negative pole of the power output terminal of the photovoltaic cell panel 200;

[0060] When configuring the first conductive strip 121, the second conductive strip 122, the first driving wheel 132 and the second driving wheel 133, the first conductive strip 121 and the second conductive strip 122 can adopt a conductive layer or copper strip arranged on the first insulating layer 115 and the second insulating layer 116. Based on this, the first driving wheel 132 and the second driving wheel 133 can be set as insulating wheels.

[0061] The power storage module 150 can store the clean electric energy converted by the photovoltaic panel 200, so as to control the operation of the control component and the driving component 130 of the photovoltaic panel cleaning mechanism 100;

[0062] In summary, please refer to Figure 1-Figure 5 The photovoltaic panel cleaning mechanism 100 realizes the dynamic connection between the photovoltaic solar panel and the energy storage device through the rail power supply principle and the battery pack energy storage method, thereby achieving the purpose of obtaining electricity from the photovoltaic solar panel, and providing a continuous supply of electric energy for the cleaning mechanism, which can greatly improve the cleaning efficiency, increase the service life of the cleaning mechanism, save energy, and promote the development of clean energy; and it also has the following advantages:

[0063] High cleaning efficiency. Traditional cleaning methods require a lot of manpower and material resources and are inefficient. The rail power supply principle and battery pack energy storage method adopted by the photovoltaic panel cleaning mechanism 100 can greatly improve the efficiency of the cleaning mechanism, thereby saving cleaning costs. The cleaning mechanism is flexible to take and put. When a group of photovoltaic panels is cleaned, it can be easily removed and placed on the next group of photovoltaic panels to be cleaned for cleaning, so that comprehensive and efficient cleaning can be achieved in a short time.

[0064] Long service life. Compared with conventional cleaning mechanisms on the market, since the guide rail bears the weight of the cleaning mechanism, the photovoltaic panel cleaning mechanism 100 reduces the pressure of the cleaning mechanism on the photovoltaic panel 200, which can extend the service life of the photovoltaic panel;

[0065] The economic benefits are high. Compared with conventional cleaning mechanisms, there is no need to carry the cleaning machine indoors for charging. When used in conjunction with the power storage module 150, long-term cleaning can be achieved, thereby improving economic benefits.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
