Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a solar panel cleaning device with a dust removal structure. Background Art

[0002] As a sustainable and clean energy source, solar energy is widely used in areas with sufficient sunlight, such as sandy areas. The generation of the photovoltaic effect of solar panels depends on their ability to receive sunlight. Long-term outdoor deployment makes it easy for dust, bird droppings and other pollutants to accumulate on the surface of solar panels, resulting in a decrease in light transmittance. The accumulation of dust and other pollutant particles can not only reduce the reception of light, but also cause the temperature of the panel to rise, further affecting the photovoltaic conversion efficiency of the solar panel.

[0003] There are many solar panel cleaning devices on the market, including manual cleaning and automated equipment. Manual cleaning methods are labor-intensive and inefficient, while existing automated cleaning devices often use dry wiping to clean. The dust generated during the cleaning process will accumulate on the solar panel again, resulting in low cleaning efficiency. In addition, some automated cleaning devices often use wet wiping to clean. The water source is continuously supplied, which wastes a lot of water resources in a dry environment.

[0004] Therefore, it is necessary to provide a solar panel cleaning device with a dust removal structure to solve the problems in the above-mentioned background technology. Utility Model Content

[0005] In response to the above-mentioned problems, the present application provides a solar panel cleaning device with a dust removal structure, which removes dust from the surface of the solar panel group by combining dry wiping and wet wiping, effectively avoiding the generation of secondary dust covering the surface of the solar panel group. At the same time, intermittent water spraying can form a higher water pressure at each spraying, which helps to more effectively remove dust, dirt and solid deposits from the surface of the solar panel group, and also helps to significantly reduce water usage.

[0006] To achieve the purpose of this application, this application provides the following technical solutions:

[0010] In a possible implementation manner, a temporary storage area is fixedly disposed on the support frame.

[0011] In a possible implementation, the cleaning roller is detachably covered with a layer of microfiber cleaning cloth.

[0012] In a possible implementation, the vertical distance between the axis center of the rotating shaft and the solar panel group is smaller than the vertical distance between the outermost side of the cleaning cloth and the axis center of the rotating shaft by 0.5-1 cm.

[0016] In a possible implementation, a control system is also provided at the bottom of the solar panel group, and the visual monitoring mechanism and the dust removal and cleaning mechanism are both electrically connected to the control system.

[0017] The beneficial effects of the utility model are:

[0018] The utility model drives the rotation of the motor to first make the cleaning roller dry-wipe the surface of the solar panel group, and then cooperates with the intermittent connection of the external water hole and the internal water hole to provide water for the surface of the solar panel group. The dust removal and cleaning mechanism removes dust and cleans the surface of the solar panel group by combining dry wiping and wet wiping, effectively avoiding the generation of secondary dust covering the surface of the solar panel group.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0029] Figure 1-Figure 6 A solar panel cleaning device with a dust removal structure provided in an embodiment of the present application includes:

[0030] A support frame 1 is fixedly mounted on the ground, with a plurality of evenly distributed solar panel groups 2 mounted on its upper end, and horizontal racks 3 are symmetrically fixed on both sides of the support frame 1; and

[0031] The dust removal and cleaning mechanism 5 is movably arranged on the row racks 3 on both sides. Specifically, the dust removal and cleaning mechanism 5 includes a shift gear meshed with the row rack 3, the shift gear is rotatably arranged in the cover 51, and a cleaning roller 54 is rotatably arranged in the cover 51 through an integrated seat 53, the shift gear is fixedly arranged with the integrated seat 53, a driving motor 52 is fixedly arranged on one side of the cover 51, and the driving motor 52 drives the shift gear and the cleaning roller 54 through the integrated seat 53. 4, the integrated seat body 53 is provided with a bearing 533, the outer ring of the bearing 533 is fixed to the rotating shaft 531, the cleaning roller 54 is fixed to the rotating shaft 531, the inner ring of the bearing 533 is fixed to the inner tube 534, and a pipe 55 is fixed to the other side of the cover shell 51, the pipe 55 is communicated with the inner tube 534, a plurality of inner water outlet holes 5341 are uniformly opened on the inner tube 534, and a plurality of outgoing water holes 5311 corresponding to the inner water outlet holes 5341 are opened on the rotating shaft 531.

[0032] On the basis of the above technical solution, during the cleaning process, the driving motor 52 is started, and the dust removal and cleaning mechanism 5 cleans from top to bottom along the solar panel group 2. The cleaning roller 54 performs dry-wiping and dust removal cleaning on the surface of the solar panel group 2 during rotation. The synchronous rotating shaft 531 rotates during rotation, and the pipe 55 supplies water to the inner tube 534. The external water hole 5311 and the internal water hole 5341 are intermittently connected. The cleaning roller 54 performs dry-wiping and wet-wiping on the surface of the solar panel group 2 during rotation, thereby effectively avoiding the generation of secondary dust covering the surface of the solar panel group 2.

[0033] In addition, based on the above scheme, the intermittent connection between the external water hole 5311 and the internal water hole 5341 enables the surface of the solar panel group 2 to be intermittently sprayed with water for cleaning, and the intermittent water spraying can form a higher water pressure at each spraying, which helps to more effectively remove dust, dirt and solid deposits on the surface of the solar panel group 2. Compared with continuous water spraying, intermittent water spraying can significantly reduce the amount of water used while ensuring the cleaning effect.

[0034] In a possible implementation, a temporary storage area 4 is fixedly provided on the support frame 1 , and the dust removal and cleaning mechanism 5 can be stopped in the temporary storage area 4 .

[0035] In one possible implementation, the cleaning roller 54 is detachably covered with a layer of microfiber cleaning cloth. On the one hand, the microfiber cleaning cloth has high adsorption capacity and good cleaning effect due to its ultra-fine fibers. On the other hand, its material is relatively soft, which prevents friction damage to the solar panel group 2 during the rotation of the cleaning cloth.

[0036] In a possible implementation, the vertical distance between the axis center of the rotating shaft 531 and the solar panel group 2 is smaller than the vertical distance between the outermost side of the cleaning cloth and the axis center of the rotating shaft 531 by 0.5-1 cm.

[0037] By adopting the above technical solution, when the dust removal and cleaning mechanism 5 stops in the temporary storage area 4, the solar panel group 2 can play a certain limiting role on the cleaning roller 54, and placing the dust removal and cleaning mechanism 5 in the temporary storage area 4 can effectively prevent the dust removal and cleaning mechanism 5 from blocking the light of the solar panel group 2.

[0038] In one possible implementation, the integrated seat body 53 also includes a shaft seat 532 fixed to the output end of the drive motor 52, the shaft seat 532 is fixed to one outer ring of the bearing 533, and the other outer ring of the bearing 533 is fixed to the rotating shaft 531.

[0039] Based on the above scheme, when the driving motor 52 drives the rotating shaft 531 to rotate, the shaft seat 532 and the rotating shaft 531 rotate synchronously, and the inner tube 534 has a small relative rotation amount due to the gravity of the water and being located in the inner ring of the bearing 533, and the outgoing water hole 5311 and the inner water hole 5341 can be intermittently connected.

[0040] In one possible implementation, a small power storage device is provided at the bottom of the solar panel group 2, which is electrically connected to the dust removal and cleaning mechanism 5. The solar panel group 2 can provide partial electrical energy to the power storage device and store it. When the solar panel group 2 needs to be cleaned, the dust removal and cleaning mechanism 5 has sufficient backup power.

[0041] In one possible implementation, a visual monitoring mechanism is fixedly provided on the cover 51. The visual monitoring mechanism can timely understand the impact of dust coverage on the photoelectric conversion efficiency by real-time monitoring of the dust accumulation on the surface of the solar panel group 2. When the dust accumulation reaches a threshold that affects the power generation efficiency, cleaning operations can be arranged to ensure that the solar panel group 2 can absorb sunlight to the maximum extent and maintain or restore its optimal working state. At the same time, visual monitoring can accurately determine when cleaning is needed to avoid unnecessary maintenance operations, thereby saving manpower, water resources and cleaning materials, and reducing overall maintenance costs.

[0042] In one possible implementation, a control system is also provided at the bottom of the solar panel group 2, and the visual monitoring mechanism and the dust removal and cleaning mechanism 5 are electrically connected to the control system. The visual monitoring mechanism detects that the dust accumulation reaches a threshold that affects the power generation efficiency, and feeds back to the control system. The control system thereby controls the operation of the dust removal and cleaning mechanism 5, realizes intelligent and unmanned cleaning management, and further improves operation and maintenance efficiency.

[0043] Working principle:

[0044] First, the dust removal and cleaning mechanism 5 is installed on the solar panel group 2, and the dust removal and cleaning mechanism 5 is connected to the power storage device, which is divided into the following two situations:

[0045] When the visual monitoring mechanism detects that the threshold of dust on the surface of the solar panel group 2 is low, the dust removal and cleaning mechanism 5 stops in the temporary storage area 4;

[0046] When the visual monitoring mechanism detects that the threshold of dust on the surface of the solar panel group 2 reaches the cleaning requirement, the visual monitoring mechanism feeds back to the control system, and the control system controls the drive motor 52 to start, and the dust removal and cleaning mechanism 5 cleans along the solar panel group 2 from top to bottom, and the cleaning roller 54 removes dust and cleans the surface of the solar panel group 2 during rotation. During the rotation of the synchronous rotating shaft 531, the pipe 55 supplies water to the inner pipe 534, and the external water hole 5311 and the internal water hole 5341 are intermittently connected, so that the dust removal and cleaning mechanism 5 removes dust and cleans the surface of the solar panel group 2 by a combination of dry wiping and wet wiping.

[0047] The above embodiments are only used to illustrate the technical solution of the present application, but not to limit it. The present application is not limited to the exact structure described above and illustrated in the accompanying drawings, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, various changes and modifications made without departing from the concept of the present application should be deemed to belong to the protection scope of the present application.
