[0027] 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.

[0028] 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.

[0029] 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.

[0030] Example 1

[0031] Reference Figure 1 , which is the first embodiment of the present invention, provides an adaptive photovoltaic panel cleaning device, which includes a bracket assembly 100, a cleaning assembly 200 and an auxiliary assembly 300. The bracket assembly 100 is installed on the photovoltaic panel assembly to move horizontally, and the cleaning assembly 200 is used to clean the photovoltaic assembly in the vertical direction. The auxiliary assembly 300 is used to accurately control the overall cleaning process and actions such as water spraying in the background.

[0032] Specifically, the support assembly 100 includes a sliding plate 101, a telescopic rod 102, and a walking member 103 for controlling the sliding plate 101 to move horizontally on the photovoltaic panel. The sliding plate 101 is connected to the telescopic rod 102, and the length of the telescopic rod 102 can be adjusted to adapt to the size of different photovoltaic panels.

[0033] Before the sliding plate 101 is connected to the telescopic rod 102, the cleaning box 201 is installed on the sliding plate 102 in advance;

[0034] At the same time, during the installation of the sliding plate 101 and the telescopic rod 102, as the telescopic rod 102 is adapted to the photovoltaic panel assembly, the groove on the walking wheel 103a in the walking member 103 will clamp the photovoltaic panel;

[0035] It is worth noting that the travel wheel 103a on the sliding plate 101 and the pulley 201b on the cleaning box 201 are both controlled to start and stop by their own travel motors.

[0036] Preferably, the cleaning assembly 200 includes a cleaning box 201 that moves on the sliding plate 101, and the cleaning box 201 slides on the sliding plate 101, but the cleaning brush head 201e can contact the photovoltaic panel assembly;

[0037] And the overall cleaning process is to first spray water on the photovoltaic panel assembly, then rotate the motor 201d-1 to control the cleaning brush head 201e to rotate, and then clean the photovoltaic panel assembly.

[0038] Preferably, the auxiliary component 300 includes a control module 301 for controlling the sliding distance and sliding direction of the sliding plate 101 and the cleaning box 201, and a water delivery box 302 for delivering water to the cleaning box 201;

[0039] The support assembly 100 is installed on the surface of the photovoltaic panel assembly, and the cleaning assembly 200 only moves on the track of the sliding plate 101.

[0040] The control module 301 can realize the sliding control of the sliding plate 101 and the cleaning box 201 , and can also control when to supply water to the cleaning box 201 .

[0041] When in use, the staff first installs the cleaning box 201 on the sliding plate 101, and installs the sliding plate 101 and the telescopic rod 102 on the photovoltaic panel assembly. The background control module 301 first controls the cleaning box 201 to slide to the upper half of the sliding plate 101, and requires that the corner edge of the photovoltaic panel assembly can also be covered when the cleaning brush head 201e rotates;

[0042] Then the control module 301 starts to clean the photovoltaic panel assembly according to the clear logic.

[0043] Example 2

[0044] Reference Figures 2 to 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0045] Specifically, a mounting male head 101a is provided at the end of the sliding plate 101, and a mounting female head 101b is provided at the other end of the sliding plate 101, a positioning pin 101a-1 is provided on the mounting male head 101a, and a gear belt 101c is also provided on the sliding plate 101. The mounting male head 101a and the mounting female head 101b are respectively used to install the telescopic rod 102, and the telescopic rod 102 is correspondingly provided with a mounting male head and a mounting female head that are installed and matched with the sliding plate 101, and the structure is consistent with the mounting male head 101a and the mounting female head 101b on the sliding plate 101, and when the mounting male head 101a is embedded in the mounting female head 101b, the positioning pin 101a-1 will rebound into the positioning groove in the mounting female head 101b, so that the installation is more stable, and the telescopic rod 102 can only be released by manual adjustment after the length is fixed.

[0046] Preferably, a travel limiter 101d is provided at each end of the sliding plate 101, and a contact point 101d-1 is provided on one of the travel limiters 101d. The DXZ-1 model can be used for the travel limiter 101d, and the power cord, battery, etc. of the travel limiter 101d are designed to be arranged in the cleaning box 201.

[0047] Preferably, the telescopic rod 102 is installed and matched with the mounting female head 101b on the sliding plate 101, and the telescopic rod 102 also includes a mounting pile 102a and a tension spring 102b fixedly connected to the mounting pile 102a, and a first node 102c is also provided inside the mounting pile 102a;

[0048] The tension spring 102b is always in a tightened state, and the tension of the tension spring 102b will always pull the walking wheel 103a toward the first node 102c;

[0049] However, since the walking wheel 103a is stuck on the photovoltaic panel when it slides on the photovoltaic panel, the tensioning spring 102b cannot pull the walking wheel 103a at this time. Only when the walking wheel 103a slides outside the photovoltaic panel and the walking wheel 103a is no longer stuck on the photovoltaic panel, the tensioning spring 102b can pull the walking wheel 103a that is separated from the photovoltaic panel back, and then the first node 102c contacts the second node 103b, so that the sliding plate 101 no longer continues to move horizontally.

[0050] Preferably, the walking member 103 includes a walking wheel 103a, on which a walking motor 103a-1 is provided, and an end of the walking wheel 103a is connected to an end of the tension spring 102b;

[0051] The end of the traveling wheel 103a is also provided with a second node 103b that cooperates with the first node 102c;

[0052] After the first node 102c is connected to the second node 103b, the travel motor 103a-1 can be controlled to stop running;

[0053] It is worth mentioning that in the photovoltaic panel assembly, although there is a gap between the photovoltaic panels, the size of the gap is generally about 5 mm. Therefore, when the walking wheel 103a encounters a gap during walking, the size of the walking wheel 103a can slide through safely. In the process of the walking wheel 103a sliding over, it will inevitably pass through the gap. At this time, the tension of the spring 102b pulling the walking wheel 103a will cause the walking wheel 103a to be pulled into the gap of the photovoltaic panel for a period of time. However, since only one walking wheel 103a may be in the gap at this time, the power of the other three walking wheels 103a will cause the walking wheel 103a that falls into the gap to leave the gap.

[0054] Preferably, the cleaning box 201 includes a guide wheel 201a sliding on the sliding plate 101, and the guide wheel 201a is located on the upper and lower surfaces of the sliding plate 101;

[0055] The cleaning box 201 also includes a pulley 201b that fits with the gear belt 101c;

[0056] The guide wheel 201a can mainly ensure that the cleaning box 201 slides only within the track without any upward or downward movement deviation, thereby ensuring the stability of cleaning to a certain extent.

[0057] Preferably, the cleaning box 201 includes a spray head 201c connected to the water delivery box 302, and a replacement plug 201d, and the replacement plug 201d includes a rotating motor 201d-1 and a component socket 201d-2 connected to the rotating motor 201d-1;

[0058] A buffer spring 201d-3 is also provided at the end of the rotating motor 201d-1 to assist the cleaning brush head 201e to achieve adaptive adjustment during cleaning. Through the setting of the buffer spring 201d-3, it can effectively achieve a certain buffering effect if hard objects are encountered during the cleaning process, so that the entire cleaning process will not be too abrupt and cause damage to the photovoltaic panel.

[0059] When in use, the staff first installs the cleaning box 201 into the sliding plate 101 so that the pulley 201b fits with the gear belt 101c, and then assembles the sliding plate 101 and the telescopic rod 102, and adjusts the telescopic rod 102 according to the size of the photovoltaic panel.

[0060] Example 3

[0061] Reference Fig.10 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0062] Specifically, the control module 301 controls the sliding plate 101 to slide to the leftmost edge of the photovoltaic panel, and controls the cleaning box 201 to be close to the uppermost edge of the photovoltaic panel, at which time the cleaning brush head 201e can cover the upper left corner edge of the photovoltaic panel;

[0063] The control module 301 controls the sliding plate 101 to gradually move toward the right side of the photovoltaic panel until two of the running wheels 103a are separated from the photovoltaic panel, and the sliding plate 101 automatically stops moving;

[0064] Control the cleaning box 201 to move downward along the sliding plate 101 by the control module 301 to a length of the cleaning box 201;

[0065] Control the sliding plate 101 to move toward the left side of the photovoltaic panel through the control module 301;

[0066] Repeat the above steps;

[0067] When the cleaning box 201 touches the contact point 101d-1, the control module 301 considers that the sliding plate 101 performs the last sweeping movement.

[0068] Preferably, when the two running wheels 103a are separated from the photovoltaic panel during the cleaning stage, the tension spring 102b pulls the running wheel 103a so that the first node 102c is connected to the second node 103b.

[0069] Preferably, when the outermost running wheel 103a encounters a gap between photovoltaic panels, the pulling force of the corresponding tensioning spring 102b is smaller than the pushing force of the remaining running wheels 103a, and the gap between the photovoltaic panels is not sufficient to support the tensioning spring 102b to pull the running wheel 103a so that the first node 102c is connected to the second node 103b.

[0070] When in use, the staff will input the cleaning program to the control module 301 at the beginning, so that the cleaning device can automatically clean according to the photovoltaic panel model. First, the cleaning box 201 will be located at the upper edge of the sliding plate 101 at the beginning. As the cleaning program proceeds, the sliding plate 101 will move horizontally along the photovoltaic panel. When it moves to the edge of the photovoltaic panel, the sliding plate 101 will automatically recognize and stop sliding. At this time, the cleaning box 201 will also move down within the sliding plate 101 by the length of the cleaning box 201, and then the sliding plate 101 starts to move horizontally in the opposite direction for cleaning;

[0071] During the entire cleaning process, spraying and moistening are performed first, and then cleaning is performed by rotating the cleaning brush head 201e.

[0072] 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 may 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.
