[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating relative importance or indicating the number of technical features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The specific implementation of the present invention is described in more detail below in conjunction with specific embodiments:

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a photovoltaic panel cleaning mechanism for cleaning a photovoltaic panel 10, wherein the photovoltaic panel 10 is tilted along a first direction X, and comprises a shell 1, an electrostatic dust collecting assembly 2, a cleaning roller 3, a suspension wheel frame 4 and a moving assembly 5; the shell 1 has a dust collecting chamber 11; the electrostatic dust collecting assembly 2 is arranged in the dust collecting chamber 11; the cleaning roller 3 is connected to the shell 1, and is used to clean the surface of the photovoltaic panel 10, sweeping the dust toward the electrostatic dust collecting assembly 2, so that the electrostatic dust collecting assembly 2 absorbs the dust; the suspension wheel frame 4 is connected to the end of the shell 1, and is used to be suspended on the upper end of the photovoltaic panel 10 along the first direction X; the moving assembly 5 is connected to the shell 1, and is used to drive the shell 1 to move along a second direction Y, and the second direction Y is perpendicular to the first direction X; wherein the outer periphery of the cleaning roller 3 is provided with bristles made of a specific material, and the electron binding ability of the specific material is stronger than the electron binding ability of the surface material of the photovoltaic panel 10. Specifically, the suspension wheel frame 4 includes at least two rotating wheels 41 rotatably connected to the shell 1, and the outer peripheral sides of the two rotating wheels 41 are in contact with the upper end surface of the photovoltaic panel 10 along the first direction X. When the moving component 5 drives the shell 1 to move along the second direction, the two rotating wheels 41 can also move along the upper end surface of the photovoltaic panel, thereby realizing the photovoltaic panel cleaning mechanism provided in this embodiment being suspended on the inclined photovoltaic panel 10 to ensure its movement stability during the cleaning process.

[0044] Furthermore, the implementation principle of this embodiment is as follows:

[0045] The outer periphery of the cleaning roller 3 is provided with bristles made of a specific material, and the electron binding ability of the specific material is stronger than the electron binding ability of the surface material of the photovoltaic panel 10. When the bristles are cleaning the photovoltaic panel, during the movement, the bristles continuously rub against the surface of the photovoltaic panel, bind the electrons of the surface material of the photovoltaic panel, so that the surface of the photovoltaic panel loses electrons and becomes positively charged, and the excess electrons that cannot be bound are released into the air in the dust collecting chamber 11. At the same time, the cleaning roller 3 rotates, and under the force generated by the cleaning roller, the dust particles are swept up and thrown in the direction of the electrostatic dust collecting component 2 in the dust collecting chamber. The electrons encounter dust particles in the process of rushing towards the electrostatic dust collecting component 2, so that the dust particles are negatively charged and adsorbed to the electrostatic dust collecting component 2, thereby realizing dust collection.

[0046] In one embodiment, the electrostatic dust collection assembly 2 includes a fixing frame 21, a discharge plate 22, a dust collecting plate 23 and a power supply 24. The discharge plate 22 and the dust collecting plate 23 are connected to the fixing frame 21 and are arranged at intervals. The discharge plate 22 and the dust collecting plate 23 are respectively electrically connected to the power supply 24. Specifically, a plurality of discharge units are provided on the discharge plate 22 to generate a tip discharge phenomenon; the dust collecting plate 23 is assembled in parallel with the discharge plate 22, and the discharge plate 22 and the dust collecting plate 23 are respectively connected to a DC voltage of opposite polarity so that the dust collecting plate 23 has a charge of a specific polarity; during the cleaning process, the dust collecting plate 23 is connected to the positive pole of the power supply, and the discharge plate 22 is connected to the negative pole of the power supply, so that the dust collecting plate 23 is in a positive polarity to adsorb dust electrons with electrons. During the dust removal process, the dust collecting plate 23 is connected to the negative pole of the power supply 24, and the discharge plate 22 is connected to the positive pole of the power supply 24. At this time, the dust collecting plate 23 is negatively charged, and the electrical properties of the dust collecting plate 23 are the same as the electrical properties of the dust particles, and a repulsive force is generated between the two. Under the action of the repulsive force, the negatively charged dust particles are pushed out of the dust collecting chamber.

[0047] In one embodiment, a driving assembly 6 is further included. There are two cleaning rollers 3. The driving assembly 6 is connected to the two cleaning rollers 3. The driving assembly 6 is used to drive the two cleaning rollers 3 to be relatively close or relatively away from each other. Specifically, the driving assembly can drive the two cleaning rollers 3 to be relatively far away from each other, so that there is enough space between the two cleaning rollers 3 for dust particles to be discharged during the dust discharge process. During the cleaning process, the driving assembly can drive the two cleaning rollers to be relatively close to each other, so as to form a certain space on both sides of the housing 1, so that dust can pass through and enter the dust collecting chamber 11.

[0048] In one embodiment, the driving assembly 6 includes a motor 61, a screw rod 62, a connecting sleeve 63, a first connecting rod 64 and a second connecting rod 65, the output end of the motor is connected to the screw rod, the screw rod is threadedly connected to the connecting sleeve, one end of the first connecting rod is rotatably connected to the connecting sleeve, the other end of the first connecting rod is rotatably connected to a cleaning roller, one end of the second connecting rod is rotatably connected to the connecting sleeve, and the other end of the second connecting rod is rotatably connected to another cleaning roller. Specifically, two moving grooves 12 for two cleaning rollers 3 to move are provided on the housing 1, and the cleaning rollers are slidably connected to the moving grooves 12, the motor 61 drives the screw rod 62 to rotate, and when the screw rod 62 rotates, it drives the connecting sleeve 63 to move along the length direction of the screw rod 62. For example, when the screw rod 62 rotates forward, the connecting sleeve 63 moves downward along the length direction of the screw rod 62. At this time, the first connecting rod 64 drives a cleaning roller on the left to move to the left in the corresponding moving groove 12, and the second connecting rod 65 drives another cleaning roller on the right to move to the right in the corresponding moving groove 12, thereby achieving the relative distance between the two cleaning rollers; when the screw rod 62 rotates reversely, the connecting sleeve 63 moves upward along the length direction of the screw rod 62. At this time, the first connecting rod 64 drives a cleaning roller on the left to move to the right in the corresponding moving groove 12, and the second connecting rod 65 drives another cleaning roller on the right to move to the left in the corresponding moving groove 12, thereby achieving the relative proximity of the two cleaning rollers. It should be noted that the forward and reverse directions in the above content only indicate that the rotation directions of the screw rod are opposite, and do not limit the specific rotation direction of the screw rod. For example, the forward direction can be counterclockwise, and the reverse direction is clockwise; similarly, the forward direction can be clockwise, and the reverse direction is counterclockwise.

[0049] In one embodiment, a vibration motor 7 is further included, and the output end of the vibration motor 7 is connected to the electrostatic dust collection assembly 2. Specifically, the number of vibration motors 7 can be determined according to the specific use requirements. In this embodiment, the number of vibration motors is preferably 3, and the 3 vibration motors are arranged at intervals along the width direction of the electrostatic dust collection assembly.

[0050] In one embodiment, the cleaning roller 3 includes a cleaning roller body 31 and a rotating motor 32. The outer periphery of the cleaning roller body 31 is provided with bristles made of a specific material, and the output end of the rotating motor 32 is connected to the cleaning roller body 31. Specifically, the rotating motor 32 is mounted and fixed on the housing 1, and the output end of the rotating motor 32 is connected to the cleaning roller body 31. The rotating motor 32 can drive the cleaning roller body 31 to rotate, thereby cleaning the surface of the photovoltaic panel 10.

[0051] In one embodiment, there are two cleaning rollers 3, and the two cleaning rollers 3 rotate in opposite directions, that is, the two cleaning rollers rotate in opposite directions. Specifically, the cleaning roller bodies 31 of the two cleaning rollers 3 are driven by different rotating motors 32, and the two rotating motors can rotate both forward and reverse. During operation, the two rotating motors 32 rotate in opposite directions.

[0052] In one embodiment, the specific material includes synthetic fibers and artificial fibers. The surface material of the photovoltaic panel is generally glass. The electron binding ability of the above two materials is greater than that of glass, thereby releasing the electrons carried by the photovoltaic panel into the air during the cleaning process.

[0053] like Figure 5 As shown, an embodiment of the present invention further provides a cleaning assembly, including any one of the photovoltaic panel cleaning mechanisms and a dust box 20 in the above embodiments, and the dust box 20 is arranged at the end of the photovoltaic panel 10 along the second direction Y. Specifically, the dust box 20 is detachably connected to the photovoltaic panel 10. After cleaning is completed, the dust box 20 can be removed from the photovoltaic panel 10, so that the dust in the dust box 20 can be cleaned. More specifically, the size of the opening on the dust box 20 should just match the size of the opening below the shell 1 or the width is greater than the size of the opening below the shell 1. A corresponding pressure sensing element can be set at the corresponding position of the opening of the dust box 20. The pressure sensing element, the power supply 24, the vibration motor 7, the rotary motor 32 and the drive assembly 6 are all connected to the controller in communication, and the communication connection method is preferably connected through a wireless communication network. When the photovoltaic panel cleaning mechanism moves to the corresponding position, the pressure sensing element can detect the corresponding pressure change and feedback to the controller, and then the controller controls the corresponding components to perform the corresponding dust collection work, thereby realizing the automatic dust collection function. It should be noted that the method for implementing the above functions is an existing technology well known to those skilled in the art, and will not be described in detail in this embodiment.

[0054] like Figures 1 to 7 As shown, an embodiment of the present invention further provides a cleaning method, using any one of the photovoltaic panel cleaning mechanisms in the above embodiments to clean the surface of the photovoltaic panel 10, the photovoltaic panel cleaning mechanism having two cleaning rollers 3, and the cleaning method comprising the following steps:

[0055] Place the suspension wheel frame 4 on the upper end of the photovoltaic panel 10 along the first direction X;

[0056] The two cleaning rollers 3 are driven to rotate in opposite directions relative to each other to sweep the dust toward the dust collecting chamber 11, and the rotation directions of the two cleaning rollers 3 are away from the central axis S, wherein the central axis S is an axis perpendicular to the midpoint position of the line connecting the centers of the two cleaning rollers;

[0057] Starting the electrostatic dust collecting component 2 so that the electrostatic dust collecting component 2 is positively charged to absorb dust;

[0058] The moving assembly 5 is started, and the moving assembly 5 drives the housing 1 to move along the second direction Y;

[0059] When moving to the dust collecting position, the two cleaning rollers 3 are driven to rotate in opposite directions relative to each other, and the rotation directions of the two cleaning rollers 3 are close to the central axis, wherein the central axis is an axis perpendicular to the midpoint position of the line connecting the centers of the two cleaning rollers 3;

[0060] The electrostatic dust collecting component 2 is started to make the electrostatic dust collecting component 2 negatively charged to repel dust, and the dust is discharged from the dust collecting chamber 11.

[0061] See also Figures 1 to 7 The embodiment shown in the figure is described below with reference to the above drawings to explain the implementation principle of the cleaning method provided in this embodiment:

[0062] When cleaning is required, the suspension wheel frame 4 is first placed on the upper end of the photovoltaic panel 10 along the first direction X, so that the photovoltaic panel cleaning mechanism provided by this embodiment is suspended on the surface of the photovoltaic panel 10 set obliquely. Then the two cleaning rollers 3 are driven to rotate in opposite directions relative to each other to sweep the dust into the dust collecting chamber 11, and the rotation directions of the two cleaning rollers 3 are away from the central axis S, wherein the central axis S is an axis perpendicular to the midpoint position of the line connecting the centers of the two cleaning rollers; specifically, as Figure 7As shown, at this time, one cleaning roller 3 rotates in direction A, and the other cleaning roller 3 rotates in direction B. The two cleaning rollers 3 sweep the dust from the surface of the photovoltaic panel 10, and the dust moves upward from the space on both sides of the shell 1 to the dust collecting chamber 11, and then can be better adsorbed by the electrostatic dust collecting component 2 in the dust collecting chamber 11, and the electrostatic dust collecting component 2 is started to make the electrostatic dust collecting component 2 positively charged to adsorb dust. During the cleaning process, the two cleaning rollers can also be driven to move away from each other, so as to realize the dust from being thrown to the middle of the electrostatic dust collecting component 2 to the two sides of the electrostatic dust collecting component 2, and the dust is thrown to different areas of the electrostatic dust collecting component 2 to avoid the middle area adsorbing too much dust and failing to adsorb new dust. The moving component 5 is started, and the moving component 5 drives the housing 1 to move along the second direction Y; when it moves to the dust collecting position, the two cleaning rollers 3 are driven to rotate in opposite directions relative to each other, and the rotation direction of the two cleaning rollers 3 is close to the central axis, wherein the central axis is an axis perpendicular to the midpoint position of the line connecting the centers of the two cleaning rollers 3; the electrostatic dust collecting component 2 is started to make the electrostatic dust collecting component 2 negatively charged, repel dust, and the dust is discharged from the dust collecting chamber 11. Specifically, at this time, one cleaning roller 3 rotates along the C direction, and the other cleaning roller 3 rotates along the D direction. During the dust collecting process, the two cleaning rollers 3 are relatively far away from each other, and a spacing area is formed between the two. The electrostatic dust collecting component 2 releases the adsorbed dust, and the two cleaning rollers 3 rotate toward the middle spacing area to generate a downward airflow, thereby better discharging the dust from the dust collecting chamber.
