[0002] In photovoltaic power generation systems, photovoltaic panels are the main light energy collection components, and their cleanliness directly affects the power generation efficiency. However, the size and shape of photovoltaic panels vary greatly depending on the application scenario and manufacturer. For example, photovoltaic panels installed on household roofs are usually small and fixed, while photovoltaic panels in large ground photovoltaic power stations are not only larger in size, but may also have different arrangements due to array design. This diversity in size and structure poses many challenges to the adaptability of cleaning equipment.

[0003] Existing photovoltaic panel cleaning devices are often designed for specific sizes and are difficult to flexibly adjust to suit photovoltaic panels of different specifications, resulting in limited applicability of the cleaning device and the inability to cover all photovoltaic panel surfaces, thus affecting the cleaning effect and power generation efficiency. In addition, the construction and installation of such devices are complicated, and often require changes to the fixed structure of the photovoltaic panel or the addition of additional supporting components, which increases installation costs and time investment. At the same time, some cleaning equipment has a low degree of automation and cannot dynamically adjust the cleaning path or force according to the size or shape of the photovoltaic panel, further reducing the cleaning efficiency.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0036] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a photovoltaic panel cleaning device, the photovoltaic panel cleaning device includes: an outer frame assembly 100, an inner frame assembly 200 and a reciprocating assembly 300.

[0037] Specifically, the external frame assembly 100 is used to be fixed on the four corners of the photovoltaic panel. There are two groups of external frame assemblies 100, one group is fixed on one side of the photovoltaic panel, and the two groups are arranged in parallel.

[0038] There are two groups of external frame assemblies 100, each group includes two external frame clamps 101 and two external frame arms 102. The two external frame arms 102 are arranged in parallel. The external frame clamps 101 are fixedly sleeved on both ends of the external frame arms 102. The external frame arms 102 are retractable. The retractable external frame arms 102 can adjust the distance between the two external frame clamps 101 to adapt to the width of the photovoltaic panel, and the external frame clamps 101 are used to clamp the side of the photovoltaic panel B.

[0039] Specifically, the inner frame assembly 200 is used to place the reciprocating assembly 300 to facilitate the cleaning of the photovoltaic panels.

[0040] The inner frame assembly 200 is arranged between the two groups of outer frame assemblies 100. The inner frame assembly 200 includes an inner frame arm 202. The inner frame arm 202 and the outer frame arm 102 have similar structures and are also retractable. The retractable inner frame arm 202 can adjust the distance between the two groups of outer frame assemblies 100 to adapt to the length of the photovoltaic panels. The end of the inner frame arm 202 cooperates with the outer frame assembly 100.

[0041] Specifically, the reciprocating assembly 300 is used to perform reciprocating motion on the inner frame assembly 200 to clean the photovoltaic panels.

[0042] The reciprocating assembly 300 is arranged in the middle of the inner frame arm 202, and includes a base 301 and a cleaning member 305. The base 301 cooperates with the inner frame arm 202, the base 301 can reciprocate on the inner frame assembly 200, and the cleaning member 305 can reciprocate on the base 301.

[0043] When in use, the cleaning member 305 can reciprocate on the base 301, and the base 301 can reciprocate on the inner frame assembly 200. The combination of the two allows the activity range of the cleaning member 305 to match the length of the photovoltaic panel; and the inner frame assembly 200 can reciprocate on the outer frame assembly 100 along the axial direction of the outer frame arm 102, so that the activity range of the cleaning member 305 matches the width of the photovoltaic panel. In this way, the photovoltaic panel cleaning device invented by us can clean photovoltaic panels of various sizes.

[0044] Example 2, reference Figure 1 to Figure 8 , which is the second embodiment of the present invention, and is based on the previous embodiment. This embodiment provides a photovoltaic panel cleaning device, comprising an outer frame assembly 100, an inner frame assembly 200, a reciprocating assembly 300 and a rolling assembly 400.

[0045] The outer frame assembly 100 is used to be fixed on the four corners of the photovoltaic panel. There are two sets of the outer frame assembly 100, one set is fixed on one side of the photovoltaic panel, and the two sets are arranged in parallel. The inner frame assembly 200 is used to place the reciprocating assembly 300 to facilitate the cleaning of the photovoltaic panel. The reciprocating assembly 300 is used to make a reciprocating motion on the inner frame assembly 200 to clean the photovoltaic panel.

[0046] Specifically, the rolling assembly 400 is used to connect the outer frame assembly 100 and the inner frame assembly 200, and also to connect the inner frame assembly 200 and the reciprocating assembly 300. The rolling assembly 400 includes a clamping roller 401 and a limit block 402. The clamping roller 401 has two parts. The middle part of the clamping roller 401 cooperates with the side of the outer frame arm 102. The limit blocks 402 are arranged at both ends of the clamping roller 401 to maintain the structure of the clamping roller 401.

[0047] A limiting hole H1 and a limiting groove K1 are provided on the limiting block 402. The limiting hole H1 is an oval hole, and both ends thereof cooperate with the ends of the clamping roller 401, so that the clamping roller 401 can rotate and translate in the limiting hole H1. The limiting groove K1 is arranged on the side of the limiting hole H1, and the position of the limiting groove K1 is in the middle of the semicircular arc of the oval limiting hole H1.

[0048] Specifically, the rolling assembly 400 further includes a limiting spring 403 , one end of which is fixedly connected to the bottom of the limiting groove K1 , and the other end of which is in the limiting hole H1 and fixedly connected to the end of the clamping roller 401 .

[0049] The limit spring 403 is installed in the limit slot K1, and one end of the limit spring 403 protrudes into the limit hole H1 by default. When the clamping roller 401 clamps the outer frame arm 102, the clamping roller 401 presses the limit spring 403 into the limit slot K1. The outer frame arm 102 includes an outer arm 102a and an inner arm 102b. The outer arm 102a is thicker than the inner arm 102b. The two can slide to adjust the length of the outer frame arm 102. When the rolling assembly 400 moves to the thinner inner arm 102b of the outer frame arm 102, it is equivalent to the outer frame arm 102 becoming thinner as a whole. The limit spring 403 releases its elastic force and pushes the clamping roller 401 to ensure that the clamping roller 401 and the outer frame arm 102 are always tightly matched. The same is true for the connection between the clamping roller 401 and the inner frame arm 202.

[0050] Specifically, the external frame clamp 101 includes a mounting end 101a and a clamping end 101b. The mounting end 101a cooperates with the end of the external frame arm 102, and the clamping end 101b cooperates with the side of the photovoltaic panel B.

[0051] The shape of the mounting end 101a matches the shape of the outer frame arm 102 and is used to be fixed on the outer frame arm 102. The surfaces facing each other of the two clamping ends 101b are provided with greater friction to clamp the photovoltaic panel.

[0052] The outer frame arm 102 includes an outer arm 102a and an inner arm 102b. One end of the inner arm 102b is arranged inside the outer arm 102a. There are two outer arms 102a and two inner arms 102b. The middle part of the clamping roller 401 cooperates with the outer arm 102a or the inner arm 102b.

[0053] The distance adjustment between the outer arm 102a and the inner arm 102b can be used to adapt to different sizes of photovoltaic panels.

[0054] Specifically, the inner frame assembly 200 further includes a mounting frame 201, which is disposed at the end of the inner frame arm 202 and cooperates with the end of the rolling assembly 400. The mounting frame 201 directly connects the inner frame assembly 200 and the rolling assembly 400 mounted on the outer frame assembly 100, and indirectly allows the inner frame assembly 200 to move axially along the outer frame assembly 100, and thus can adjust the position of the reciprocating assembly 300 on the photovoltaic panel along the width direction.

[0055] Specifically, the inner frame assembly 200 further includes an extension piece 203, one end of which is fixedly matched with the mounting frame 201, and the other end of which is provided with a rack 203a, which passes through the side of the base and slidably matches with the base 301. The rack 203a of the extension piece 203 can also be separated from the base 301.

[0056] The mounting frame 201 includes a first connection end 201a, a second connection end 201b and a third connection end 201c. The first connection end 201a is fixedly connected to the end of the extension member 203 to ensure that the position of the extension member 203 on the mounting frame 201 remains unchanged; the second connection end 201b is fixedly connected to the end of the inner frame arm 202, and the connection method is similar to the connection between the mounting end 101a of the outer frame clamp 101 and the outer frame arm 102; the third connection end 201c is slidably matched with the side of the rolling assembly 400, and the third connection end 201c can adjust the depth of the rolling assembly 400 to control the pressure between the cleaning member 305 of the reciprocating assembly 300 and the photovoltaic panel, thereby controlling the strength and effect of cleaning.

[0057] The bottom of the reciprocating assembly 300 cooperates with the inner frame arm 202 of the inner frame assembly 200 through two sets of rolling assemblies 400. Similarly, the inner frame arm 202 here also has an inner arm and an outer arm, and the rolling assembly 400 here can also adapt to the inner frame arm 202 of different thicknesses.

[0058] Specifically, the base 301 is provided with a screw hole H2 and an extension hole H3, the extension holes H3 are arranged on both sides of the base 301, and the screw hole H2 is arranged at the top between the two extension holes H3. The extension hole H3 cooperates with the rack 203a of the extension piece 203.

[0059] Specifically, the reciprocating assembly 300 also includes a screw rod 303 and a transmission member 304. The two ends of the screw rod 303 are matched with the screw rod hole H2. When the screw rod 303 rotates in one direction, the cleaning member 305 matched with it can reciprocate along the groove pattern of the screw rod 303. The movement of the cleaning member 305 on the base 301 does not need to consider the change of direction.

[0060] The transmission member 304 cooperates with the extension member 203. The transmission member 304 includes a gear 304a, a groove wheel 304b, a transmission shaft 304c and a belt 304d. The transmission shaft 304c has a gear 304a at one end and a groove wheel 304b at the other end. The bottom of the transmission shaft 304c rotates with the base 301. There are four gears 304a, four groove wheels 304b and four transmission shafts 304c, and two belts 304d. The gear 304a includes a driving gear, a passive gear and two transmission gears. The transmission shaft 304c where the driving gear is located is driven by an external power. The driving gear and the passive gear are meshed. The transmission gear and the rack 203a are engaged. Meshing, one belt 304d connects the driving gear and the groove wheel 304b on the transmission gear, and the other belt 304d connects the driven gear and the groove wheel 304b on the transmission gear. When the driving gear rotates, the power is transmitted to the transmission gear through the belt 304d, or transmitted to the transmission gear through the driven gear and the belt 304d, so that the two driven gears rotate in opposite directions. Because the tooth surfaces of the two racks 203a are facing each other, the two driven gears are between the tooth surfaces of the two racks 203a, which can ensure that the movement of the base 301 will not be interfered with by the movement of the driven gear.

[0061] The cleaning member 305 is provided with a reciprocating block 305a, a cleaning tube 305b and a cleaning brush 305c. The reciprocating block 305a cooperates with the middle part of the screw rod 303. The cleaning tube 305b is arranged at the top of the reciprocating block 305a and bends toward the photovoltaic panel B. The cleaning brush 305c is arranged at the end of the cleaning tube 305b and fits with the photovoltaic panel B.

[0062] A rotatable wedge block is provided inside the reciprocating block 305 a , and the wedge block cooperates with the groove on the screw rod 303 , so that the rotation of the screw rod 303 allows the reciprocating block 305 a to reciprocate on the screw rod 303 .

[0063] Specifically, the reciprocating assembly 300 further includes a protection plate 302 and a reversing switch 306 . The protection plate 302 is disposed on the top of the extension member 203 and the transmission member 304 ; the reversing switch 306 is disposed on the base 301 and in the axial direction of the extension member 203 .

[0064] The protection plate 302 isolates the extension member 203 and the transmission member 304 below the screw rod 303 and the cleaning member 305 to prevent liquid from splashing onto the extension member 203 and the transmission member 304 during the cleaning process.

[0065] A buffer cone spring is provided on the reversing switch 306 to ensure trigger sensitivity while giving the motor driving the reciprocating assembly 300 time to stop, thereby preventing the reversing switch 306 from being damaged.

[0066] There are two reversing switches 306, both of which are arranged at a position directly opposite to the rack 203a of the extension member 203. At the same time, the reversing switches 306 are set so that when one of the reversing switches 306 is triggered, the motor driving the active gear will stop and rotate in the opposite direction, so that the moving direction of the reciprocating component 300 on the inner frame component 200 is reversed, and when the two reversing switches 306 are continuously triggered at the same time, the motor driving the active gear will stop and no longer rotate.

[0067] When the length of the inner frame arm 202 of the inner frame assembly 200 is adjusted to adapt to the length of the photovoltaic panel, the adaptable range is also limited, limited to the length of the base 301 to twice the length of the base 301. When the length of the photovoltaic panel is longer than the length of the base 301, the reciprocating assembly 300 will only engage with both racks 203a when it is in the middle part, and the movement of the reciprocating assembly 300 will make the extended hole H3 at one end insert into the rack 203a, and the extended hole H3 at the other end will be separated from the rack 203a. At this time, when the reciprocating assembly 300 moves to the edge, the reversing switch 306 will be triggered, causing the reciprocating assembly 300 to stop and reverse. When the length of the photovoltaic panel is equal to the length of the base 301, both racks 203a trigger the reversing switch 306. At this time, the reciprocating assembly 300 does not need to translate on the inner frame assembly 200, and only the cleaning member 305 needs to translate on the base 301 to clean the photovoltaic panel.

[0068] When in use, when the length of the photovoltaic panel is longer than the length of the base 301 and shorter than twice the length of the base 301, the cleaning member 305 can reciprocate on the base 301, and the base 301 can reciprocate on the inner frame assembly 200. At the same time, when the reciprocating assembly 300 moves to the edge of the photovoltaic panel, the rack 203a in the movement direction of the reciprocating assembly 300 will trigger the reversing switch 306 opposite to the rack 203a, causing the reciprocating assembly 300 to stop and reverse, so that the activity range of the cleaning member 305 matches the length of the photovoltaic panel.

[0069] When the length of the photovoltaic panel is equal to the length of the base 301, the cleaning member 305 can still reciprocate on the base 301, but because both reversing switches 306 are triggered, the base 301 will not reciprocate on the inner frame assembly 200, which also allows the activity range of the cleaning member 305 to match the length of the photovoltaic panel.

[0070] In addition, the inner frame assembly 200 can reciprocate along the axial direction of the outer frame arm 102 on the outer frame assembly 100, so that the range of movement of the cleaning member 305 matches the width of the photovoltaic panel, so that the photovoltaic panel cleaning device invented by us can clean photovoltaic panels of various sizes.

[0071] Example 3, reference Figure 1 to Figure 9 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0072] This embodiment provides a method for using a photovoltaic panel cleaning device, including adapting the width of the photovoltaic panel; adapting the length of the photovoltaic panel; and cleaning the photovoltaic panel.

[0073] Adapting the width of the photovoltaic panel includes adjusting the length of the outer frame arm 102 so that the clamping end 101b of the outer frame clamp 101 clamps the two sides of the photovoltaic panel B; in this way, the inner frame assembly 200 can reciprocate on the outer frame assembly 100 along the axial direction of the outer frame arm 102.

[0074] Adapting the length of the photovoltaic panel includes installing the rolling assembly 400 on the outer frame arm 102, adjusting the length of the inner frame arm 202, and matching the third connection end 201c of the mounting frame 201 with the rolling assembly 400; when the length of the photovoltaic panel is longer than the length of the base 301 and shorter than twice the length of the base 301, the reciprocating assembly 300 can reciprocate along the axial direction of the inner frame arm 202 on the inner frame assembly 200, and the cleaning member 305 can reciprocate along the axial direction of the inner frame arm 202 on the base 301. When the length of the photovoltaic panel is equal to the length of the base 301, the reciprocating assembly 300 cannot reciprocate along the axial direction of the inner frame arm 202 on the inner frame assembly 200, but the cleaning member 305 can still reciprocate along the axial direction of the inner frame arm 202 on the base 301.

[0075] Cleaning the photovoltaic panel includes allowing the rolling assembly 400 on the inner frame arm 202 to adjust the axial position of the reciprocating assembly 300 on the outer frame arm 102, and then cleaning the photovoltaic panel B along the axial direction of the inner frame arm 202. After the cleaning is completed at the position where the inner frame arm is located, the rolling assembly 400 on the outer frame arm 102 is adjusted to move the position of the inner frame assembly 200 to clean the next part of the photovoltaic panel B.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
