Description

Technical Field

[0001] The utility model relates to the field of photovoltaic panel cleaning equipment, in particular to a cleaning device with internal air blowing and a photovoltaic cleaning robot. Background Art

[0002] Since photovoltaic panels need to be placed outdoors for power generation, after long-term use, dust and other attachments will adhere to the surface of the photovoltaic panels. These attachments will block light, thereby reducing the power generation efficiency of the photovoltaic panels.

[0003] Currently, the main cleaning methods for photovoltaic panels are: manually holding a cleaning rod for cleaning, and a robot driving a brush to move on the surface of the photovoltaic panel for cleaning. For the above two cleaning methods, a disc cleaning brush can be used. The bristles of the disc cleaning brush contact the photovoltaic panel, and the rotation axis of the disc cleaning brush during rotation is substantially perpendicular to the photovoltaic panel, and the attachments on the surface of the photovoltaic panel are removed during rotation.

[0004] During the cleaning process of the cleaning brush, the bristles of the cleaning brush will contact the attachments on the photovoltaic panel. After some attachments are peeled off from the surface of the photovoltaic panel, they will adhere to the bristles. After long-term use, a large amount of attachments will adhere to the bristles of the cleaning brush. At this time, if the dirty cleaning brush is used to clean the photovoltaic panel, the attachments of the cleaning brush will adhere to the photovoltaic panel, resulting in a poor cleaning effect on the photovoltaic panel and even an increase in the attachments on the photovoltaic panel.

[0005] Currently, the cleaning of the bristles is that workers regularly remove the cleaning brush and then manually clean the cleaning brush. Since the attachments on the bristles cannot be removed in time, as the attachments on the cleaning brush increase, the difficulty of peeling off the attachments from the bristles will gradually increase. Especially after the attachments on the bristles come into contact with water, the peeling difficulty will further increase.

[0006] In order to better maintain the clean state of the bristles, it is now necessary to shorten the interval for cleaning the cleaning brush as much as possible, which increases the labor intensity of workers and the maintenance cost. Content of the Utility Model

[0007] The utility model aims to solve the above problems, and provides a cleaning device with internal air blowing and a photovoltaic cleaning robot, which solve the above problems.

[0008] A cleaning device with internal air blowing includes: a cleaning brush, a mounting frame, an air pump, an air path connector and a motor. The motor drives the cleaning brush to rotate relative to the mounting frame. The cleaning brush includes bristles and a base plate. The upper ends of the bristles are fixedly connected to the base plate. The bristles are arranged in a ring. Both ends of the air path connector are respectively communicated with the air pump and an internal air blowing port. The internal air blowing port is located inside the ring formed by the bristles.

[0009] Further, it further includes a rotating shaft, the rotating shaft is fixedly connected to the substrate, the motor drives the rotating shaft to rotate, the rotating shaft is rotatably connected to the mounting frame, the rotating shaft is a hollow shaft, the position of the air path connector relative to the mounting frame is fixed, and the air path connector is connected to the rotating shaft.

[0010] Optionally, the air path connector is a rotary joint, one end of the air path connector is fixedly connected to the mounting frame, the other end is fixedly connected to the rotating shaft, and the internal blowing port is the lower end of the inner cavity of the rotating shaft.

[0011] Optionally, the air path connector includes an air pipe, and the air path connector penetrates into the inner cavity of the rotating shaft.

[0012] Further, the air pipe includes a straight pipe and a bent pipe, the straight pipe passes through the rotating shaft, the bent pipe is located below the rotating shaft, the straight pipe and the bent pipe are integrally formed, and the air outlet of the bent pipe faces forward.

[0013] Further, the air path connector further includes a first bearing, and the inner ring and the outer ring of the first bearing are respectively fixedly connected to the air pipe and the inner wall of the rotating shaft.

[0014] Further, the internal blowing port is the lower end of the inner cavity of the rotating shaft or the lower end of the air pipe.

[0015] Further, it further includes a blowing pipe, the blowing pipe is located outside the ring formed by the brush hairs, the blowing pipe is located behind the cleaning brush, the blowing pipe is communicated with an air pump, and the air outlet of the blowing pipe faces forward.

[0016] A photovoltaic cleaning robot using the cleaning device with internal blowing further includes a robot body and a connecting pipe. The mounting frame is located in front of the vehicle body of the robot body, the air pump is fixedly installed inside the vehicle body, and both ends of the connecting pipe are respectively communicated with the air pump and the air path connector.

[0017] Further, it further includes a fixing frame and a driving mechanism. The driving mechanism is respectively connected to the mounting frame and the fixing frame. The driving mechanism drives the mounting frame to move up and down relative to the fixing frame. The fixing frame is fixedly connected to the vehicle body, and the connecting pipe is a flexible pipe.

[0018] The utility model has the following advantages:

[0019] 1. When the cleaning brush cleans the photovoltaic panel, the air pump compresses air, and the blowing pipe blows the compressed air onto the brush hairs of the cleaning brush, blowing off the attachments that have just adhered to the brush hairs, ensuring the cleanliness of the brush hairs, thus ensuring the cleaning effect on the photovoltaic panel. At the same time, it prolongs the period of manually cleaning the cleaning brush, reduces the labor and maintenance costs.

[0020] 2. Use the internal air port to blow air from the inside to the outside of the brush, and the air pipe to blow air from the outside of the brush, so as to clean the inner and outer bristles at the same time, avoiding the problem of poor cleaning effect of the outer or inner bristles caused by only using the internal air port or the air pipe;

[0021] 3. When no cleaning operation is performed, the drive mechanism drives the mounting frame to rise, so that the cleaning brush is out of contact with the photovoltaic panel, reducing the resistance of the crawler robot during movement, thereby reducing power consumption and improving endurance.

[0033] Embodiment 1:

[0034] As Figures 1 to 6 shown, a cleaning device with internal air blowing includes: a cleaning brush 1, a mounting bracket 3, an air pump 6, an air path connector 7, and a motor 31. The motor 31 drives the cleaning brush 1 to rotate relative to the mounting bracket 3. The cleaning brush 1 includes bristles 11 and a base plate 13. The upper ends of the bristles 11 are fixedly connected to the base plate 13. The bristles 11 are arranged in a ring. Both ends of the air path connector 7 are respectively communicated with the air pump 6 and an internal air blowing port, and the internal air blowing port is located inside the ring formed by the bristles 11. It should be noted that the ring formed by the bristles 11 can be a circle, an ellipse, a polygon, or a ring formed by a complex curve.

[0035] Furthermore, it further includes a rotating shaft 14. The rotating shaft 14 is fixedly connected to the base plate 13. The motor 31 drives the rotating shaft 14 to rotate. The rotating shaft 14 is rotatably connected to the mounting bracket 3. The rotating shaft 14 is a hollow shaft. The air path connector 7 is fixed in position relative to the mounting bracket 3, and the air path connector 7 is connected to the rotating shaft 14. Herein, the air path connector 7 being fixed in position relative to the mounting bracket 3 means that at least a part of the air path connector 7 is fixed in position relative to the mounting bracket 3.

[0036] Optionally, as Figure 4 shown, the air path connector 7 is a rotary joint. One end of the air path connector 7 is fixedly connected to the mounting bracket 3, and the other end is fixedly connected to the rotating shaft 14. The internal air blowing port is the lower end of the inner cavity of the rotating shaft 14. The direction of the air flow is from the air pump, through the air path connector 7, into the inner cavity of the rotating shaft 14, and finally discharged from the lower end of the inner cavity of the rotating shaft 14. After the air flow passes through the inner bristles 11, the attachments on the surface of the bristles 11 are blown off.

[0037] This embodiment has a simple structure, but since the airflow blown out from the lower end of the inner cavity of the rotating shaft 14 is directed in all directions, the strength of the airflow is slightly weak.

[0038] Optionally, the air circuit connector 7 includes an air pipe, and the air circuit connector 7 penetrates into the inner cavity of the rotating shaft 14 .

[0039] Optionally, when the internal air outlet is the lower end of the inner cavity of the rotating shaft 14, there is a gap between the air path connector 7 and the inner cavity of the rotating shaft 14 to avoid friction between the two. This method has a simple structure, but the airflow strength is slightly weak and the gap leaks.

[0040] Optionally, the air pipe includes a straight pipe 71 and a bent pipe 73, the straight pipe 71 passes through the rotating shaft 14, the bent pipe 73 is located below the rotating shaft 14, the straight pipe 71 and the bent pipe 73 are integrally formed, and the air outlet of the bent pipe 73 is an internal air outlet and faces forward. In this embodiment, the airflow provided by the air pump 6 is blown out in only one direction, the intensity of the airflow is relatively large, and the cleaning effect of the attachments on the surface of the inner bristles 11 is better.

[0041] It should be noted that the front is the movement direction of the mounting bracket 3 during cleaning in this embodiment, and the bending tube 73 faces forward, which can blow the attachments blown off the surface of the bristles 11 forward to prevent the attachments from moving backward to the area that has been cleaned.

[0042] Furthermore, the air path connector 7 further comprises a first bearing 74, the inner ring and the outer ring of the first bearing 74 are respectively fixedly connected to the air pipe and the inner wall of the rotating shaft 14. The first bearing 74 supports the air pipe and improves the stability of the air pipe.

[0043] The internal air blowing port has a better cleaning effect on the bristles 11 on the inner side, but if there are many layers of bristles 11, it may not be possible to blow through the bristles on the outer side.

[0044] Furthermore, it also includes an air blowing pipe 5, which is located outside the ring formed by the bristles 11, and is located behind the cleaning brush 1. The air blowing pipe 5 is connected to the air pump 6, and the air outlet of the air blowing pipe 5 faces forward. The air blowing pipe 5 cleans the surface of the outer bristles 11, and cooperates with the internal air blowing port to clean the outer and inner bristles at the same time, achieving a better cleaning effect.

[0045] During operation, the mounting frame 3 is mounted on a cleaning rod (not shown) or a robot, and moves under the drive of manpower or the robot, and the cleaning brush 1 rotates to clean the photovoltaic panel area along the cleaning path. During the cleaning process of the cleaning brush 1, the air pump 6 works, and the internal air blowing port and the air blowing pipe 5 respectively blow away the attachments attached to the inner and outer bristles 11 from the bristles 11.

[0046] Embodiment 2:

[0047] As Figures 1 to 6 shown, a photovoltaic cleaning robot using the internal blowing cleaning device further includes a robot body 2 and a connecting pipe 70. The mounting bracket 3 is located in front of the vehicle body 21 of the robot body 2. The air pump 6 is fixedly installed inside the vehicle body 21. Two ends of the connecting pipe 70 are respectively communicated with the air pump 6 and the air path connector 7.

[0048] Furthermore, it further includes a fixing bracket 4 and a driving mechanism 41. The driving mechanism 41 is respectively connected with the mounting bracket 3 and the fixing bracket 4. The driving mechanism 41 drives the mounting bracket 3 to move up and down relative to the fixing bracket 4. The fixing bracket 4 is fixedly connected with the vehicle body 21. The connecting pipe 70 is a flexible pipe.

[0049] Furthermore, a screw is used to threadedly connect through the fixing plate 52 and the threaded hole of the vehicle body 21 to press and fix the blowing pipe 5 to the vehicle body 21.

[0050] Furthermore, it further includes a solenoid valve 61. The air inlet of the solenoid valve 61 is communicated with the air pump 6, and the air outlet is communicated with the blowing pipe 5 and the connecting pipe 70.

[0051] Furthermore, the air pipe further includes a sliding pipe 72. One end of the straight pipe 71 away from the bent pipe 7 is integrally formed with the sliding pipe 72. The sliding pipe 72 is slidably connected with the vehicle body 21.

[0052] During operation, the mounting bracket 3 is driven by the driving mechanism 41 to move up and down relative to the vehicle body 21, so that the brush bristles 11 can contact the photovoltaic panel. The blowing pipe 5 can be fixed to the vehicle body 21 or the mounting bracket 3. When fixed to the mounting bracket 3, a flexible pipe with a length redundancy is used to connect between the blowing pipe 5 and the air pump 6.

[0053] The above has described the present invention by way of example, but the present invention is not limited to the above specific embodiments. Any modification or variation based on the present invention falls within the scope of protection required by the present invention.
