Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic panel cleaning devices, and in particular to a cleaning device for manually cleaning photovoltaic panels. Background Technology

[0002] With the rapid development of the photovoltaic industry, the number of photovoltaic power plants is also increasing. To ensure the proper operation of photovoltaic power plants, post-construction maintenance is essential. A crucial aspect of this is maintaining the cleanliness of the photovoltaic panels, preventing them from being covered by dust, sand, and other contaminants that could affect power generation efficiency. Therefore, regular cleaning of the photovoltaic panels is a vital step in ensuring the smooth operation of a photovoltaic power plant.

[0003] Currently, although photovoltaic (PV) cleaning robots are rapidly developing, they may not be suitable for certain special scenarios. These include PV panels that are scattered or have significant elevation differences that prevent the installation of robot tracks. In such cases, using cleaning robots would greatly increase cleaning costs, making manual cleaning more appropriate. Common manual cleaning methods currently include using water guns or brushes. However, water guns are difficult to use in certain environments, and manually cleaning each PV panel with a brush is extremely inefficient. Utility Model Content

The second connecting shaft 313 facilitates the rotatable connection of the second side travel wheel 330 to the second connecting shaft 313.

[0043] In some embodiments, see Figure 2 , Figure 3 and Figure 4 A fifth bearing 241 connects the first side traveling wheel 240 to the first connecting shaft 213, making the first side traveling wheel 240 rotate more smoothly. A sixth bearing 331 connects the second side traveling wheel 330 to the second connecting shaft 313, making the second side traveling wheel 330 rotate more smoothly.

[0044] In some embodiments, see Figure 2 , Figure 3 and Figure 4A first lifting lug 212 is detachably connected to the lower part of the motor base 210, and a second lifting lug 312 can be used to suspend heavy objects. The first lifting lug 212 is used to hang batteries or other heavy objects to reduce the burden on cleaning personnel. A threaded hole is provided below the first connecting shaft 213, and the threaded part of the upper end of the first lifting lug 212 is screwed into the threaded hole of the first connecting shaft 213. The first lifting lug 212 can also prevent the fifth bearing 241 from disengaging from the first connecting shaft 213, thereby preventing the first side traveling wheel 240 from disengaging from the first connecting shaft 213.

[0045] In some embodiments, see Figure 3 , Figure 4 and Figure 5 The second traveling component 300 is mounted on the higher end of the photovoltaic panel 400, and a pull rod 340 is connected to the pivot seat 310. The photovoltaic panel 400 is installed at an angle, and the second traveling component 300 is installed on the higher end of the photovoltaic panel 400. The pull rod 340 is provided to facilitate cleaning personnel to pull the second traveling component 300 to move it.

[0046] In some embodiments, see Figure 3 , Figure 4 and Figure 5 A second lifting lug 312 is detachably connected to the lower part of the pivot seat 310. The pull rod 340 is connected to the second lifting lug 312. The lifting lug facilitates the connection of the pull rod 340 and transmits the pulling force to the pivot seat 310. A threaded hole is provided at the lower part of the second connecting shaft 313. The threaded part at the upper end of the second lifting lug 312 is screwed into the threaded hole of the second connecting shaft 313. The second lifting lug 312 can also prevent the sixth bearing 331 from disengaging from the second connecting shaft 313, thereby preventing the second side traveling wheel 330 from disengaging from the second connecting shaft 313.

[0047] In some embodiments, see Figure 3 , Figure 4 and Figure 5 A chain 341 connects the second lifting lug 312 to the pull rod 340. The chain 341 increases the spatial flexibility of the pull rod 340, allowing cleaning personnel to adjust the pull rod 340 to a suitable position for pulling.

[0048] In some embodiments, see Figure 1 , Figure 2 and Figure 5 A push rod 250 is connected to the motor base 210. By setting the push rod 250, cleaning personnel can easily hold and operate the pull rod 340, thereby driving the motor base 210 to move.

[0049] In some embodiments, see Figure 1 , Figure 2 and Figure 5The push rod 250 is Z-shaped, with one end connected to the motor base 210 and the other end having a handle 251. When the cleaning device is installed on the photovoltaic panel 400, the handle 251 is further away from the photovoltaic panel 400 relative to the motor base 210. The Z-shaped push rod 250, with one end mounted on the motor base 210 and bent twice in the middle, further distances the other end from the photovoltaic panel 400, resulting in a greater distance between the handle 251 and the photovoltaic panel 400. This provides the handle 251 with more operating space, making it easier for cleaning personnel to grip.

[0050] The working principle of the cleaning device for manually cleaning photovoltaic panels according to the embodiments of this application is as follows: the drive motor 220 drives the roller brush 100 to rotate, and two cleaners work together to clean the photovoltaic panel 400. One cleaner holds the push rod 250 on the front of the photovoltaic panel 400 to make the first upper traveling wheel 230 and the first side traveling wheel 240 close to the lower edge of the photovoltaic panel 400. The drive motor 220 is powered by the battery pack carried on his body, which drives the roller brush 100 to clean. The speed of the drive motor 220 can be controlled by the speed adjustment device to ensure a good cleaning effect. The other cleaner is on the other side of the photovoltaic panel 400. He holds the pull rod 340 to make the second upper traveling wheel 320 and the second side traveling wheel 330 close to the photovoltaic panel 400, while pulling the roller brush 100 forward in the cleaning direction.
