Description

Technical Field

[0001] This application relates to the technical field of photovoltaic panel cleaning devices, and particularly to a photovoltaic cleaning drive wheel set and a cleaning robot. Background Art

[0002] A photovoltaic panel is composed of multiple photovoltaic cells. When sunlight shines on the photovoltaic cells, light energy is converted into electrical energy, generating direct current. The power generation efficiency of a photovoltaic panel depends on the amount of solar radiation it receives, and the cleanliness of the photovoltaic panel surface directly affects the absorption efficiency of solar radiation.

[0003] In practical applications, pollutants such as dust and sand are likely to accumulate on the surface of the photovoltaic panel. These pollutants will block sunlight, reduce the light transmittance of the photovoltaic panel, and thus affect the power generation efficiency of the photovoltaic panel.

[0004] Currently, there are various photovoltaic panel cleaning solutions on the market, mainly including manual cleaning, automatic sprinkler systems, manual cleaning tools, and cleaning robots. Among them, manual cleaning and manual cleaning tools are inefficient and labor-intensive; automatic sprinkler systems consume a large amount of water resources and are not suitable for use in arid regions; while cleaning robots have become a research hotspot and development trend in the field of photovoltaic panel cleaning due to their high degree of automation, good cleaning efficiency, and water resource conservation.

[0005] Existing photovoltaic panel cleaning robots mainly move on the surface of the photovoltaic panel through rail, wheeled or tracked walking mechanisms, and use roller brushes to remove dust. However, due to the gaps between adjacent photovoltaic panels, existing tracked cleaning robots have poor stability when crossing the edges of photovoltaic panels, resulting in a large impact on the edges of the photovoltaic panels, which will damage the photovoltaic panels over time. Therefore, a drive wheel set that can smoothly cross the edges of photovoltaic panels is needed. Utility Model Content

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other.

[0034] The photovoltaic panel is composed of multiple photovoltaic cells. When sunlight shines on the photovoltaic cells, the light energy is converted into electrical energy, generating direct current. The power generation efficiency of the photovoltaic panel depends on the amount of solar radiation it receives, and the cleanliness of the surface of the photovoltaic panel directly affects the absorption efficiency of solar radiation.

[0035] In actual applications, pollutants such as dust and sand are easily accumulated on the surface of photovoltaic panels. These pollutants will block sunlight, reduce the transmittance of photovoltaic panels, and thus affect the power generation efficiency of photovoltaic panels.

[0036] At present, there are many photovoltaic panel cleaning solutions on the market, mainly including manual cleaning, automatic spraying system, manual cleaning tools and cleaning robots, etc. Among them, manual cleaning and manual cleaning tools are inefficient and labor-intensive; automatic spraying system consumes a lot of water resources and is not suitable for use in arid areas; and cleaning robots have become a research hotspot and development trend in the field of photovoltaic panel cleaning due to their advantages such as high degree of automation, good cleaning efficiency and water conservation.

[0037] Existing photovoltaic panel cleaning robots mainly move on the surface of photovoltaic panels through rails, wheels or crawler walking mechanisms, and use roller brushes to remove dust. However, due to the gaps between adjacent photovoltaic panels, the existing crawler cleaning robots have poor stability when crossing the edge of the photovoltaic panel, resulting in a large impact on the edge of the photovoltaic panel, which will damage the photovoltaic panel over a long period of time. Therefore, a driving wheel set that can smoothly cross the edge of the photovoltaic panel is needed.

[0038] Based on this, an exemplary embodiment of the present application provides a photovoltaic cleaning drive wheel group, which is symmetrically arranged on both sides of the cleaning robot body and is used to drive the cleaning robot to walk; the driving wheel group includes a driving unit, a driving wheel, a passive wheel and a floating wheel group, and the driving unit is connected to the driving wheel in a transmission manner; the driving wheel and the passive wheel are externally meshed and connected with a track; the floating wheel group is arranged between the driving wheel and the passive wheel, so that when the cleaning robot body crosses the edge of the photovoltaic panel, the floating wheel group can float and support the track between the driving wheel and the passive wheel according to the driving conditions, so that the driving wheel group can smoothly cross the edge of the photovoltaic panel and reduce the impact on the edge of the photovoltaic panel.

[0039] An exemplary embodiment of the present application provides a photovoltaic cleaning drive wheel group, such as Figure 1 and 2 The photovoltaic cleaning driving wheel set comprises a driving unit 10, a driving wheel 20, a passive wheel 30 and a floating wheel set 50. The driving unit 10 is connected to the driving wheel 20 by transmission. The driving unit 10 is preferably a motor to drive the driving wheel 20 to rotate. The driving wheel 20 and the passive wheel 30 are externally meshed and connected with a track 40. The floating wheel set 50 is arranged between the driving wheel 20 and the passive wheel 30. The floating wheel set 50 has the function of floating adjustment to support the track 40. The floating wheel set 50 can floatingly support the track 40 between the driving wheel 20 and the passive wheel 30 according to the driving working conditions, adapt to various uneven bearing surfaces, keep the track 40 in tension, and make the driving wheel set smoothly cross the edge of the photovoltaic panel to reduce the impact on the edge of the photovoltaic panel.

[0040] likeFigure 3 As shown in the figure, the floating wheel set 50 includes a mounting plate 501. Both ends of the mounting plate 501 are connected to a mounting bracket 502 through a floating adjustment assembly 503. The mounting bracket 502 is connected to the cleaning robot body 2. At least one set of floating wheels 504 is arranged on the mounting plate 501. In this way, when the cleaning robot crosses two adjacent photovoltaic panels, the floating wheel set 50 can float up and down when crossing the gap between the two photovoltaic panels to adjust the support for the crawler 40, so that the cleaning robot can smoothly cross from one photovoltaic panel to another. At the same time, during the process of crossing the photovoltaic panel, since the up and down floating of the cleaning robot is small, the impact and vibration on the photovoltaic panel are small, reducing the impact and vibration on the edge of the photovoltaic panel.

[0041] Multiple sets of floating wheels 504 can be arranged on the mounting plate 501. Multiple sets of floating wheels 504 share one mounting plate 501, which can reduce the installation and processing costs. Preferably, the mounting plate 501 is provided with four sets of floating wheels 504.

The top and bottom of the elastic element are respectively abutted against the floating support and the mounting plate 501. Preferably, the elastic element is a spring. During the driving process of the cleaning robot, the elastic element can provide elastic force adjustment according to the driving working conditions, so that the cleaning robot can adapt to the bearing surfaces of various working conditions.

[0043] In one embodiment, first grooves arranged along the circumferential direction are provided on the circumferential surfaces of the driving wheel 20 and the driven wheel 30. Second protrusions adapted to the first grooves are provided on the inner side surface of the crawler 40. When the crawler 40 meshes with the driving wheel 20 and the driven wheel 30, the second protrusions are engaged in the first grooves to position the crawler 40 and enhance the meshing strength between the crawler 40 and the driving wheel 20 and the driven wheel 30.

[0044] In one embodiment, first protrusions arranged along the circumferential direction are provided on the circumferential surfaces of the driving wheel 20 and the driven wheel 30. Second grooves adapted to the first protrusions are provided on the inner side surface of the crawler 40. When the crawler 40 meshes with the driving wheel 20 and the driven wheel 30, the first protrusions are engaged in the second grooves to position the crawler 40 and enhance the meshing strength between the crawler 40 and the driving wheel 20 and the driven wheel 30.

[0045] In one embodiment, one of the driving wheel 20 or the driven wheel 30 has a first groove arranged along the circumferential direction on its circumferential surface, and a second protrusion adapted to the first groove is arranged on the inner side surface of the crawler belt 40; or one of the driving wheel 20 or the driven wheel 30 has a first protrusion arranged along the circumferential direction on its circumferential surface, and a second groove adapted to the first protrusion is arranged on the inner side surface of the crawler belt 40.
