Description

Technical Field

[0002] Photovoltaic power generation, as a clean, renewable energy source, has been widely adopted worldwide, particularly in my country's Gobi Desert, a region of northwest China. Due to its vast, flat terrain and abundant photovoltaic resources, a large number of large-scale centralized photovoltaic power plants have been built. However, the region is subject to intense wind and sand activity. During the normal operation of photovoltaic power plants, solar panels are often affected by the deposition of atmospheric dust and pollutants, seriously affecting their power generation efficiency. Therefore, the ability to effectively clean solar panels to increase photovoltaic production capacity is particularly important.

[0003] Therefore, the research on cleaning solar panels is increasing. In the prior art, solar panels are cleaned by a cleaning mechanism. For example, Chinese invention patent CN104993784A discloses a solar panel cleaning device, which includes rollers provided at both ends of the solar panel and extending along the ends of the solar panel, and a brush is provided on the roller. Guide rails parallel to each other are provided on both sides of the solar panel, and the roller can move along the guide roller on the surface of the solar panel to clean the solar panel. However, the brush on the roller contacts the solar panel, and when the roller moves along the surface of the solar panel, the roller can only wipe the solar panel in one direction to clean it, so the cleaning efficiency is not high, and the cleaning effect of the solar panel is not ideal. In addition, Chinese invention patent CN118199506A discloses an anti- A cleaning device for sputtered solar panels includes a mounting cover connected along one side of the solar panel, a mounting seat is provided on one side of the mounting cover, and a driving mechanism is also provided inside the mounting cover to drive the mounting seat to move along the surface of the solar panel. The mounting seat is driven to move on the surface of the solar panel by the driving mechanism. In addition, a flushing nozzle is provided below the mounting seat, and splash guards are provided on both sides of the mounting seat. The flushing nozzle flushes the surface of the solar panel, and the splash guard follows the movement of the mounting seat to clean the surface of the solar panel. The device cleans the solar panel by flushing and wiping, but water spray cleaning causes water stains on the one hand, and on the other hand, since the above-mentioned wiping method is also one-way wiping, the cleaning of the solar panel is not ideal.

[0004] Therefore, the present invention aims to provide a solar panel cleaning device, which changes the one-way wiping cleaning method in the prior art and improves the cleaning effect on the solar panel. Utility Model Content

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. 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.

[0039] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0040] like Figure 1 as well as Figure 2As shown, it is a structural schematic diagram of the cleaning equipment in this embodiment assembled on the solar panel. The cleaning equipment in this embodiment is used to clean the solar panel, thereby ensuring the cleanliness of the solar panel and ensuring the utilization efficiency of the solar panel.

[0041] In this embodiment, guide rails are provided on both sides of the solar panel, and the cleaning equipment is provided on the surface of the solar panel and can move along the solar panel to clean the solar panel. The cleaning equipment in this embodiment includes a walking system 100 symmetrically installed on both sides of the solar panel, and a driving system 200 is connected between the walking system 100, and a cleaning system 300 is installed on the driving system 200. In this embodiment, the walking system 100 moves along the length direction of the solar panel to drive the cleaning system 300 to move along the length direction of the solar panel, and the driving system 200 can drive the cleaning system 300 to move along the width direction of the solar panel. In this embodiment, the walking system 100 and the driving system 200 can drive the cleaning system 300 to move on the surface of the solar panel to clean the solar panel.

[0042] like Figure 3 As shown, the walking system 100 in this embodiment includes a frame 101 symmetrically arranged on the solar panel guide rail, and one side of the frame 101 is open, and the guide rail on the solar panel enters the opening, and a suspension wheel 105 is installed on the top wall of the opening of the frame 101. The suspension wheel 105 allows the walking system 100 to be suspended on the guide rail of the solar panel. In addition, a rotating rod 102 is rotatably installed in the frame 101, and a walking wheel 103 is installed on the rotating rod 102. The walking wheel 103 abuts against the side wall of the guide rail. In this embodiment, a walking drive motor 104 is installed in the frame 101. The walking drive motor 104 can drive the rotating rod 102 to drive the walking wheel 103 to rotate through the cooperation of the bevel gear, thereby realizing walking along the length direction of the solar panel, which is used to adjust the position of the cleaning system 300 on the solar panel.

[0043] like Figure 4 as well as Figure 5As shown, in this embodiment, the drive system 200 includes a distance drive motor 201 and a threaded rod 202 connected to the output end of the distance drive motor 201. In this embodiment, the distance drive motor 201 is installed on the frame 101, and one end of the threaded rod 202 is connected to the output end of the distance drive motor 201, and the other end passes through the cleaning system 300 and is rotatably assembled on the walking system 100 on the other side. The cleaning system 300 is threadedly assembled on the threaded rod 202. In this embodiment, a fixed guide rail 203 is also installed between the frames 101. The fixed guide rail 203 passes through the cleaning system 300 and is slidably assembled with the cleaning system 300. In this embodiment, the distance drive motor 201 drives the threaded rod 202 to rotate when it is working. The rotation of the threaded rod 202 can drive the cleaning system 300 to move along the width direction of the solar panel to adjust the position of the cleaning system 300.

[0044] like Figure 5 As shown, the cleaning system 300 in this embodiment includes a cleaning unit 301 and a wiping unit 302. In this embodiment, the wiping unit 302 abuts against the surface of the solar panel, and the wiping unit 302 wipes the surface of the solar panel. The cleaning unit 301 is used to blow away the dust generated after wiping by the wiping unit 302, thereby cleaning the solar panel.

[0045] like Figure 5 as well as Figure 6 As shown, the wiping unit 302 in this embodiment is installed below the cleaning unit 301. The wiping unit 302 includes an electric push rod 302c installed on the lower surface of the cleaning unit 301 and a cleaning bar 302a located on the surface of the solar panel. The cleaning bars 302a are arranged side by side and are connected in turn by connecting rods 302b. The connecting rod 302b and the cleaning bar 302a are in a rotational connection state. It is worth noting that the end of the electric push rod 302c in this embodiment is also rotatably connected to the arc rod 302d, and the other end of the arc rod 302d is rotatably connected to the cleaning bar 302a away from the electric push rod 302c. When the solar panel needs to be wiped, the electric push rod 302c extends or contracts during operation. The arc-shaped rod 302d drives the cleaning bar 302a connected to it to deflect relative to the adjacent cleaning bar 302a. During the deflection, the cleaning bars 302a move away from or closer to each other. At the same time, the connecting rod 302b and the cleaning bar 302a rotate relative to each other, thereby realizing the deflection of the cleaning bar 302a on the surface of the solar panel to achieve synchronous wiping in the longitudinal and transverse directions. When the wiping unit 302 follows the walking system 100 in the movement, the cleaning bars 302a wipe the local area of the solar panel multiple times due to moving away from or approaching each other, including forward wiping and reverse wiping, thereby improving the cleaning efficiency of the solar panel, solving the defect of only one-way wiping in the prior art, and ensuring the cleaning effect.

[0046] In addition, if Figure 4 、 Figure 5 as well as Figure 7 As shown, a cleaning unit 301 is further provided above the wiping unit 302 in this embodiment. After the wiping unit 302 wipes the dust on the surface of the solar panel, the cleaning unit 301 sprays the dust and blows the dust away, thereby ensuring the cleaning effect of the solar panel. Figure 7 、 Figure 8 as well as Figure 9 As shown, the cleaning unit 301 in this embodiment also includes a shell 301a, an electric push rod 302c is installed on the lower surface of the shell 301a, the threaded rod 202 passes through the shell 301a and is threadedly assembled with the shell 301a, and the fixed guide rail 203 passes through the shell 301a and is slidingly assembled with the shell 301a. In this embodiment, the bottom of the shell 301a is symmetrically inclined with an air outlet 301b, and the sprayed gas is sprayed toward the surface of the solar panel through the air outlet 301b to blow away the dust on the surface of the solar panel.

[0047] like Figure 8 as well as Figure 9 As shown, in this embodiment, a fixing frame 301c is fixedly installed in the shell 301a, and a connecting frame 301d is also carried on the lower surface of the fixing frame 301c. In this embodiment, there is a cavity between the connecting frame 301d and the fixing frame 301c, and a spring 301g is also installed in the cavity, and the spring 301g is in a compressed state. In addition, a connecting plate 301e is connected to the connecting frame 301d, and a pressing block 301f is connected to the connecting plate 301e. An opening is provided on the shell 301a, and the pressing block 301f passes through the opening and presses on the surface of the cleaning strip 302a. In this embodiment, since the spring 301g is in a compressed state, the elastic force drives the connecting frame 301d and the fixing frame 301c to overlap tightly on the one hand, and on the other hand, the pressing block 301f on the connecting plate 301e is tightly pressed against the surface of the cleaning strip 302a, thereby avoiding the problem that the cleaning strip 302a is separated from the solar panel and cannot play a cleaning role.

[0048] It is worth noting that the connecting frame 301d is also equipped with a power supply 301m, which is used to power the electrical components in the cleaning equipment. On the other hand, the cleaning equipment can also act as a counterweight, thereby increasing the weight of the connecting frame 301d, ensuring the effect of the pressing block 301f pressing the cleaning strip 302a, and further avoiding the problem of the cleaning strip 302a separating from the surface of the solar panel.

[0049] like Figure 9As shown, a fan 301n is symmetrically installed on the fixing frame 301c in this embodiment. When the fan 301n is working, it can spray air from the air outlet 302b of the shell 301a, so that the dust generated after wiping by the wiping unit 302 is blown away by the air flow, which is used to efficiently clean the solar panel and ensure the cleaning effect.

[0050] It is also worth noting that a thin-film solar photovoltaic panel is also provided on the surface of the shell 301a in this embodiment. The thin-film solar photovoltaic panel can convert solar energy into electrical energy and store it in the power supply 301m, thereby being used to power the electrical components in the cleaning equipment. In addition, a raindrop sensor is also provided on the shell 301a. When the raindrop sensor senses rain, it stops cleaning the solar panel. On the one hand, it avoids the problem of water stains on the solar panel when cleaning. On the other hand, the cleaning equipment stops working when the solar panel is cleaned by rainwater, thereby ensuring the service life of the cleaning equipment. In addition, a distance sensor is also provided on the walking system 100. The distance sensor is used to sense the walking distance of the cleaning equipment. After reaching the preset value, it moves in the opposite direction, thereby realizing the reciprocating movement of the cleaning equipment on the solar panel.

[0051] On the other hand, this embodiment also provides a method for cleaning solar panels using the above-mentioned cleaning equipment. Specifically, the walking system 100 drives the cleaning system 300 to move along the length direction of the solar panel on the surface of the solar panel, and the driving system 200 drives the cleaning system 300 to move along the width direction of the solar panel. At the same time, the wiping unit 302 in the cleaning system 300 wipes the solar panel in multiple directions, and the cleaning unit 301 blows away the dust generated by the wiping unit 302 to achieve the cleaning purpose.

[0052] The specific wiping steps of the wiping unit 302 are: the electric push rod 302c extends or shortens, and the cleaning bar 302a is driven to deflect through the arc rod 302d. During the deflection, the cleaning bars 302a move away from or closer to each other, and the cleaning bars 302a wipe the surface of the solar panel longitudinally and transversely synchronously, thereby achieving multi-directional wiping, ensuring the wiping effect, and improving cleaning efficiency.

[0053] The fan 301n in the cleaning unit 301 works to blow air from the air outlet 301b to the surface of the solar panel, blowing away the dust generated by the wiping unit 302, thereby ensuring the cleaning effect of the cleaning equipment on the solar panel.

[0054] In addition, the synchronous action of the power supply 301m and the spring 301g in this embodiment enables the pressing block 301f to always press against the surface of the cleaning strip 302a, ensuring that the cleaning strip 302a is always in contact with the solar panel during the deflection process, further improving the cleaning efficiency of the cleaning equipment on the solar panel and ensuring the cleaning effect.

[0055] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
