[0062] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0063] Please refer to the attached Figure 1 To Attachment Figure 7 The present application embodiment provides a cleaning device 100. In the present embodiment, the cleaning device 100 is mainly used to clean the photovoltaic panel 200 (please refer to the attached Figure 8 To Attachment Fig.11 ) is used as an example for illustration. However, the cleaning device 100 can also clean other objects, which is not specifically limited in this embodiment.

[0064] Please refer to the attached Figure 1 and attached Figure 2The cleaning device 100 includes a mobile frame 110, and the mobile frame 110 is used to be movably connected to the photovoltaic panel 200 so that the mobile frame 110 moves relative to the photovoltaic panel 200. Exemplarily, the mobile frame 110 is provided with a driving wheel (not shown in the figure) and a plurality of walking driven wheels 111, wherein the driving wheel is used to be connected to the power output member to drive the mobile frame 110 to move on the photovoltaic panel 200. In addition, the provision of a plurality of walking driven wheels 111 can improve the stability of the mobile frame 110 during movement. It should be noted that, in this embodiment, the driving wheel and the plurality of walking driven wheels 111 are rubber wheels, which can reduce the wear on the photovoltaic panel 200 and improve the service life of the photovoltaic panel 200.

[0065] Please refer to the attached Figure 3 , Attachment Figure 6 And attached Figure 7 In some embodiments, the mobile frame 110 may include a first support plate 112 and a second support plate 113. When the mobile frame 110 is movably connected to the photovoltaic panel 200, the first support plate 112 and the second support plate 113 are arranged at intervals along the width direction of the photovoltaic panel 200; Figure 3 Arranged in the middle M direction.

[0066] The travel driven wheels 111 can be respectively arranged on the surfaces opposite to the first support plate 112 and the second support plate 113. For example, the number of driven wheels among the plurality of travel driven wheels 111 is four, two travel driven wheels 111 are arranged on the first support plate 112 at intervals, and two travel driven wheels 111 are arranged on the second support plate 113 at intervals. It should be noted that the travel driven wheels 111 can be installed in the mobile frame 110 through the connecting plate 114. For example, the connecting plate 114 is provided with a mounting hole, and the travel driven wheel 111 is rotatably connected in the mounting hole to realize the installation of the travel driven wheel 111 and the mobile frame 110.

[0067] It should be noted that the mobile frame 110 also includes a plurality of legs 115. For example, part of the plurality of legs 115 is arranged at the bottom of the first support plate 112, and the remaining part is arranged at the bottom of the second support plate 113. With such an arrangement, when the cleaning device 100 is not cleaning the photovoltaic panel 200, it can be directly placed on other bearing surfaces, for example, it can be directly placed on the ground. In this example, the number of the plurality of legs 115 can be three, four or even more. Exemplarily, the number of the legs 115 is four.

[0068] The cleaning device 100 further includes a dust removal assembly 120, which is disposed on the mobile frame 110 and is located at the front end of the moving direction of the mobile frame 110. For example, the dust removal assembly 120 is disposed between the first support plate 112 and the second support plate 113. It should be noted that the moving direction of the mobile frame 110 in this embodiment can be Figure 8 The N direction in .

[0069] The dust removal assembly 120 is configured to absorb dirt or impurities on the photovoltaic panel 200; it should be noted that the impurities may include dust, leaves or bird droppings.

[0070] The cleaning device 100 further includes a cleaning brush roller assembly 131, which is disposed on the mobile frame 110. For example, the cleaning brush roller assembly 131 is disposed between the first support plate 112 and the second support plate 113 and is located at the rear end of the moving direction of the mobile frame 110; or, in other words, in the moving direction of the mobile frame 110, the cleaning brush roller assembly 131 is located behind the dust removal assembly 120. The cleaning brush roller assembly 131 is configured to clean the surface of the photovoltaic panel 200.

[0071] The cleaning device 100 further includes a spray assembly 132, which is disposed on the mobile frame 110 and located on one side of the cleaning brush roller assembly 131; the spray assembly 132 is configured to spray a cleaning medium onto the photovoltaic panel 200. It should be understood that the cleaning medium may include cleaning water, a special cleaning agent, or a mixed solution of cleaning water and a special cleaning agent.

[0072] The cleaning device 100 for photovoltaic panels of photovoltaic power plants provided in this embodiment includes a dust removal component 120, a cleaning brush roller component 131, and a spray component 132 that complement each other. During the cleaning process, the dust removal component 120 works first to effectively absorb and remove most of the dust, particulate matter and other impurities on the surface of the photovoltaic panel 200, laying a good foundation for the subsequent cleaning steps. Subsequently, the spray component 132 sprays the cleaning medium, and uses the cleaning brush roller component 131 to further clean the surface of the photovoltaic panel in depth to remove stubborn stains, which significantly improves the cleaning efficiency and cleaning effect of the cleaning device 100, thereby significantly improving the cleanliness of the photovoltaic panel 200, and helping to improve the energy storage efficiency of the photovoltaic panel 200.

[0073] It should be noted that there are multiple options for the type of dust removal component 120. For example, the dust removal component may include a dust suction device, an electrostatic dust collector, or a mechanical brushing device.

[0074] For example, please refer to the attached Figure 3 To Attachment Figure 5The dust removal assembly 120 includes a dust removal housing 121 and a dust removal brush roller 122. The dust removal housing 121 includes a dust collection chamber and a dust suction chamber that are interconnected. The dust suction chamber has a dust suction and exhaust port. The dust suction and exhaust port faces the photovoltaic panel 200. For example, please refer to the attached Figure 4 and attached Figure 5 The dust suction and discharge port is arranged on the lower surface of the dust suction chamber 124 so that impurities can be quickly adsorbed into the dust suction chamber 124. In other words, the dust removal housing 121 includes a first dust removal housing 1211 and a second dust removal housing 1212, and the inner cavities of the first dust removal housing 1211 and the second dust removal housing 1212 are interconnected, wherein the inner cavity of the first dust removal housing 1211 constitutes an integrated cavity, and the inner cavity of the second dust removal housing 1212 constitutes a dust suction cavity.

[0075] The dust removal brush roller 122 is rotatably connected in the dust collection chamber. For example, mounting holes 125 are respectively provided on the walls opposite to each other of the first dust removal housing 1211, and the two mounting holes 125 are opposite to each other. In this way, one end of the dust removal brush roller 122 is rotatably connected in one of the mounting holes 125, and the other end of the dust removal brush roller 122 is rotatably connected in the other mounting hole 125.

[0076] The dust removal brush roller 122 is configured to drive impurities into the dust collection chamber 123 through the dust suction and discharge port. The dust removal assembly 120 can effectively clean stains or impurities on the surface of the photovoltaic panel 200. The rotation of the dust removal brush roller 122 not only helps to loosen and sweep away stubborn dirt, but also the setting of the dust suction and discharge port ensures that these loosened impurities can be quickly sucked into the dust suction chamber 124, and further sucked into the dust collection chamber 124 through the dust suction action, thereby achieving an efficient and comprehensive dust removal effect.

[0077] It should be noted that, in order to improve the rotation stability of the dust removal brush roller 122 , a bearing may be provided in each mounting hole 125 .

[0078] Please refer to the attached Figure 3 The dust removal assembly 120 and the cleaning brush roller assembly 131 are arranged obliquely relative to the horizontal plane; that is, there is an angle between the extension direction M of the dust removal assembly 120 and the horizontal direction X. In this way, it can be ensured that the dust removal assembly 120 and the cleaning brush roller assembly 131 match the inclination direction of the photovoltaic panel 200, which is conducive to better cleaning of the photovoltaic panel 200 and improves the cleaning effect of the photovoltaic panel 200.

[0079] Please refer to the attached Figure 3 To Attachment Figure 7 The dust removal housing 121 includes a dust collection outlet 126, which is disposed at the lower end of the dust collection chamber 123 and communicates with the dust collection chamber 123. Figure 3 Taking the orientation shown as an example, the dust collecting outlet 126 is arranged at the lower left of the dust removing housing 121 .

[0080] The dust collection assembly provided in this embodiment is provided with a dust collection outlet 126, which is precisely arranged at the lower end of the dust collection chamber 123 and maintains an unobstructed connection with the dust collection chamber 123. Such a layout ensures that all impurities captured by the dust collection assembly 120 can be smoothly discharged through the dust collection outlet 126 with the assistance of gravity and the airflow formed by the dust removal brush roller 122, and enter the subsequent collection or processing system. In addition, the design of the dust collection outlet 126 also takes into account sealing and easy maintenance to ensure that dust leakage does not occur during the dust removal process, and facilitates the user to perform cleaning and maintenance work.

[0081] In order to facilitate the collection of dust passing through the dust collection outlet 126, the dust collection assembly 120 provided in this embodiment includes a dust collection duct 127, which is arranged at the dust collection outlet 126 and is sealed and connected to the dust collection outlet 126. The dust collection duct 127 serves as a bridge connecting the dust collection outlet 126 and subsequent collection devices (such as dust collection bags, dust collection boxes, etc.), ensuring that the dust and impurities removed from the surface of the photovoltaic panel 200 can smoothly and efficiently enter the dust collection duct 127 through the dust collection outlet 126, and finally be effectively collected, effectively avoiding the loss of impurities during the transmission process, and improving the overall efficiency of dust removal and collection.

[0082] In addition, the dust collecting duct 127 makes the collection process of impurities more centralized and orderly, which is convenient for subsequent cleaning and maintenance. When the impurities in the dust collecting duct accumulate to a certain extent, it can be easily removed for cleaning without disassembling the entire dust removal assembly 120, thereby saving time and labor costs.

[0083] It should be noted that in this embodiment, the dust collecting pipe 127 can be a curved pipe of a specific size, or a corrugated pipe. When the dust collecting pipe 127 is a corrugated pipe, the length and outlet direction of the dust collecting pipe 127 can be adjusted according to actual conditions, which is conducive to improving the connection between the dust collecting pipe 127 and the subsequent collection device.

[0084] In one possible implementation, the spray assembly 132 includes a first spray rod 1321 and a second spray rod 1322, and the first spray rod 1321 and the second spray rod 1322 are respectively located on both sides of the cleaning brush roller assembly 131, and the first spray rod 1321 is also located between the cleaning brush roller assembly 131 and the dust removal assembly 120; in other words, in the walking direction of the mobile frame 110, the first spray rod 1321 is located in front of the cleaning brush roller assembly 131, and the second spray rod 1322 is located behind the cleaning brush roller assembly 131.

[0085] The cleaning medium sprayed by the first spray bar 1321 is used to moisten the stains on the photovoltaic panel 200 , and the cleaning medium sprayed by the second spray bar 1322 is used to spray clean the photovoltaic panel 200 .

[0086] The cleaning medium (such as water, cleaning liquid, etc.) is first sprayed onto the surface of the photovoltaic panel 200 through the first spray bar 1321. The cleaning medium can initially wet, soften or decompose the stains, making the subsequent brushing action of the cleaning brush roller more efficient. In addition, the front first spray bar 1321 can effectively reduce the wear between the cleaning brush roller and the dry or hardened stains, reduce the friction between the cleaning brush roller and the stains, thereby reducing the degree of wear of the cleaning brush roller and the photovoltaic panel 200, and increasing the service life of the cleaning brush roller and the photovoltaic panel 200. Afterwards, the cleaning medium sprayed by the second spray bar 1322 is used to perform deep spray cleaning on the photovoltaic panel 200, which can more effectively remove these softened stains, thereby significantly improving the cleaning efficiency of the cleaning device 100.

[0087] In this example, the first spray bar 1321 can be parallel to the axis of the cleaning brush roller. If the first spray bar 1321 is not parallel to the cleaning brush roller, the sprayed water flow may deviate from the preset spray path, resulting in insufficient or excessive cleaning of some areas, affecting the cleaning effect. Therefore, the present application specifies that the second spray bar 1322 is parallel to the axis of the cleaning brush roller, which helps to ensure that the water spray acts evenly and effectively on the cleaning brush roller, thereby avoiding the problem of uneven water spray or poor water spray effect caused by improper water spray angle, and maximizing the cleaning effect.

[0088] In order to further improve the spraying effect of the cleaning medium, a plurality of nozzles may be provided on the first spray bar 1321, and the plurality of nozzles are spaced apart along the length direction of the first spray bar 1321. In the embodiment of the present application, the number of nozzles is not limited, and can be specifically set according to actual needs. In addition, the setting position of the nozzle is not limited. For example, a plurality of nozzles may be spaced apart on the side of the first spray bar 1321, and the spray end of the nozzle faces the surface of the cleaning brush roller. In this way, by adjusting the shape and size of the nozzle, the flow rate and speed of the fluid can be controlled, thereby meeting the demand for the amount of cleaning medium in different use environments, while making the direction of the spray more concentrated, thereby maximizing the cleaning effect.

[0089] In this embodiment, the end of the second spray rod 1322 extends toward the dust collecting outlet 126 so that the end of the second spray rod 1322 is disposed adjacent to the dust collecting outlet 126 ; the second spray rod 1322 is also configured to provide atomized fluid near the dust collecting outlet 126 to suppress dust at the dust collecting outlet 126 .

[0090] In other words, the second spray rod 1322 may include a first part and a second part that are connected to each other, wherein the extension direction of the first part is parallel to the axial direction of the cleaning brush roller, and the extension direction of the second part intersects with the axial direction of the cleaning brush roller, so that the end of the second part away from the first part is arranged near the dust collection outlet 126.

[0091] In this way, the second spray bar 1322 is configured to provide atomized fluid near the dust collection outlet 126. The atomized liquid can be water or other suitable cleaning liquids, and its fine water mist particles can effectively absorb and settle dust particles in the air, preventing secondary dust from being generated during the dust removal process, thereby improving the dust removal effect and cleaning efficiency.

[0092] In order to further improve the spraying effect of the cleaning medium, a plurality of nozzles may be provided on the second spray bar 1322, and the plurality of nozzles are arranged at intervals along the length direction of the first portion of the second spray bar 1322. The layout of the nozzles on the second spray bar 1322 is consistent with the layout of the nozzles on the first spray bar 1321, and this embodiment will not be described in detail.

[0093] In one possible implementation, the cleaning brush roller assembly 131 includes a cleaning brush roller and an internal outer rotor DC synchronous motor, and the cleaning brush roller is arranged on the housing of the internal outer rotor DC synchronous motor so that the internal outer rotor DC synchronous motor is used to drive the cleaning brush roller to rotate relative to the movable frame 110.

[0094] The cleaning device 100 further includes a driving shaft 142 and a reducer 143 . The driving shaft 142 is rotatably connected to the moving frame 110 , and a driving wheel (not shown in the figure) is sleeved on the driving shaft 142 .

[0095] The output shaft of the built-in outer rotor DC synchronous motor is connected to the dust brush roller 122 through the first transmission member 144, so that the cleaning brush roller and the dust brush roller 122 rotate synchronously; for example, the output shaft of the built-in outer rotor DC synchronous motor is connected to the roller shaft of the dust brush roller 122 through the first transmission member 144; the dust brush roller 122 is also connected to the reducer 143 through the second transmission member (not shown in the figure), and the output end of the reducer 143 is connected to the drive shaft 142, thereby driving the entire cleaning device 100 to move on the photovoltaic panel 200. The first transmission member 144 and the second transmission member are conventional transmission structures, for example, the first transmission member 144 and the second transmission member can be belt transmission mechanisms.

[0096] This embodiment uses the design of a built-in outer rotor DC synchronous motor and a first transmission member to enable the dust removal brush roller 122 to rotate synchronously with the cleaning roller brush, thereby ensuring the coordination and consistency of the two brush rollers during the cleaning process, improving the cleaning effect, and reducing the wear and noise that may be caused by brush roller asynchronism.

[0097] In addition, it can also be connected to the drive shaft 142 through a second transmission member and a reducer 143. The reducer 143 is used to reduce the output speed of the built-in outer rotor DC synchronous motor, increase the torque, achieve simultaneous walking and cleaning operations, and greatly improve the cleaning efficiency.

[0098] In a possible implementation, the cleaning device 100 also includes at least two guide shoe assemblies 150, each guide shoe assembly 150 includes a first guide member 151 and a second guide member 152, and the first guide member 151 is arranged on the photovoltaic panel, for example, the first guide member 151 is arranged on the fixed frame of the photovoltaic panel.

[0099] The second guide member 152 is disposed on the moving frame 110 and is slidably connected to the first guide member 151. With such a configuration, the moving frame 110 can provide a stable moving track, effectively preventing the moving frame from deflecting or shaking during the cleaning process, thereby improving the stability of the cleaning operation. In addition, the wear of the photovoltaic panel 200 can be reduced, thereby improving the service life of the photovoltaic panel 200.

[0100] It should be noted that the guide shoe assembly 150 can have multiple options. For example, the first guide member 151 can be a guide groove, and the second guide member 152 can be a guide wheel that cooperates with the guide groove. The guide wheel can move along the guide groove to reduce the direct contact and friction between the movable frame 110 and the surface of the photovoltaic panel 200 or other non-guide components, thereby reducing wear and noise.

[0101] In a possible implementation, the cleaning device 100 further includes a liquid supply member 160, which is connected to the first spray bar 1321 and the second spray bar 1322 through a liquid supply pipe 161, respectively, to provide a cleaning medium to the first spray bar 1321 and the second spray bar 1322, which helps to ensure the cleaning effect of the cleaning device 100. It should be noted that the liquid supply member 160 can be disposed on the mobile frame 110, or on one side of the mobile frame 110.

[0102] In other embodiments, the liquid supply member 160 further includes a water pump 162, which connects the liquid supply member 160 and the first spray bar 1321 through a liquid supply pipe 161, and connects the liquid supply member 160 and the second spray bar 1322 through a liquid supply pipe 161 to provide power for the cleaning medium.

[0103] Please refer to the attached Figure 8 To Attachment Fig.11 An embodiment of the present application also provides a cleaning device, which includes a drone 300 and a cleaning device 100 for photovoltaic panels of a photovoltaic power station as described in any of the above embodiments, and the cleaning device 100 is connected to the drone 300 via an integrated coaxial winch mechanism 170.

[0104] In this embodiment, the cleaning device 100 is driven by the drone 300. The drone 300 can fly over obstacles and reach areas that are difficult for traditional cleaning equipment to reach, such as photovoltaic panel installation locations such as roofs, mountains, and above water areas. This high flexibility and wide accessibility greatly expand the application scope of the cleaning device, making cleaning operations more comprehensive and efficient.

[0105] In addition, the cleaning device 100 is connected to the drone 300 through an integrated coaxial hoisting mechanism 170, and the height of the cleaning device 100 can be adjusted by the integrated coaxial hoisting mechanism 170. With this arrangement, whether it is a flat roof, a sloping hillside or the top of a building with a complex structure, precise height adjustment can be used to ensure effective contact between the cleaning device 100 and the surface of the photovoltaic panel 200, so that the cleaning device can more flexibly adapt to the surfaces of the photovoltaic panels 200 of different heights and angles.

[0106] It should be noted that, since the cleaning device includes the cleaning apparatus 100 described in any of the above embodiments, the cleaning device has the structure and beneficial effects of the cleaning apparatus 100, and this embodiment will not be described in detail herein.

[0107] In one possible implementation, the photovoltaic panel cleaning equipment for a photovoltaic power station also includes an electrical controller unit (not shown in the figure) and a power supply (not shown in the figure); the electrical control unit and the power supply are both arranged in the casing of the drone 300.

[0108] A speed sensor (not shown in the figure) is arranged in the reducer 143 of the cleaning device 100, and the speed sensor is used to detect the rotation speed of the first output end; the controller is connected to both the speed sensor and the drone 300, and is used to synchronize the speed of the drone 300 according to the speed sensor, so that the drone 300 and the cleaning device 100 can be better matched.

[0109] And / or, the cleaning device 100 is provided with a position sensor (not shown in the figure), the position sensor is connected to the controller, and the electrical control unit controls the working state of the driving component 140 of the cleaning device 100 according to the position sensor. For example, the position sensor is used to detect whether there is a photovoltaic panel 200 in front of it, and then control the start or stop of the driving component 140. When it is detected that there is no photovoltaic panel in front or the boundary of the working area is reached, the controller can automatically stop the operation of the driving component 140 to prevent the cleaning device 100 from continuing to move and possibly causing a collision or fall accident. This automatic stop function enhances the safety of the operation process and protects equipment and personnel from potential harm.

It should be understood that a water source sealing sleeve 176 is also provided at the liquid outlet 1712 to achieve the sealing of the liquid outlet 1712 and prevent the cleaning medium from leaking.

[0112] The hoisting part includes a hoisting DC synchronous motor 172 and a first drum 173 connected to the output shaft of the hoisting DC synchronous motor 172, wherein the first drum 173 is sleeved on the hoisting main shaft 171, and the first drum 173 is connected to the mobile frame 110 through a soft cable 174; wherein the number of the first drums 173 can be one or two. As a soft connection, the soft cable 174 has higher flexibility than a rigid connection, so that the UAV can adjust its posture and position more flexibly during flight, while avoiding the hard defects caused by the rigid connection, thereby avoiding unsafe factors such as explosion caused by sudden wind pressure, and improving the operation safety of the equipment.

[0113] The collector ring 175 is sleeved on the winch main shaft 171; the electrical control unit is connected to the cleaning device 100 through the collector ring 175, for example, the electrical control unit is connected to the built-in outer rotor DC synchronous motor through the collector ring 175.
