Description

Technical Field

[0001] The utility model relates to the field of photovoltaic panels, in particular to a cleaning device for photovoltaic panels. Background Art

[0002] Photovoltaic panels, commonly known as solar panels, are devices that convert solar energy directly into electrical energy. They use the photovoltaic effect to convert light energy into electrical energy. When in use, photovoltaic panels are usually installed side by side in open areas using brackets.

[0003] Since photovoltaic panels are directly installed in open areas, dust will float on the top of the panels when they are in use. The dust on the panels will affect the efficiency of the panels in converting light energy into electrical energy, so the surface of the panels needs to be wiped and cleaned regularly.

[0004] When wiping and cleaning the surface of the photovoltaic panel, it is usually done manually with a hand-held cleaning board. However, when cleaning the surface of the photovoltaic panel manually with a hand-held cleaning board, not only is it necessary to give the cleaning board an extrusion force to ensure the cleaning board and the photovoltaic panel are wiped evenly, but also a supporting force is required to prevent the cleaning board from sliding off the photovoltaic panel. As a result, the staff's arms will ache after working for a long time, and it is inconvenient that the cleaning board can only slide on the photovoltaic panel when working. Utility Model Content

A cleaning plate 2 is installed at the bottom of the mounting plate 1. The cleaning plate 2 is composed of a wrapped cloth and a sponge board. The threaded sleeve 4 is rotatably installed on the top of the mounting plate 1 through the hinge 5. The threaded sleeve 4 can be connected to an operating handle, so that the mounting plate 1 and the cleaning plate 2 are pushed to slide on the photovoltaic panel by the operating handle, so that the cleaning plate 2 wipes and cleans the surface of the photovoltaic panel. A guide assembly 3 is arranged on the side of the mounting plate 1. The guide assembly 3 comprises a limit plate 31, a connecting assembly 34, a limit roller 32 and a support The support roller 33 and the limit plate 31 are installed on the end of the mounting plate 1 through the connecting assembly 34. The limit roller 32 is vertically rotatably installed on the limit plate 31. The support roller 33 is rotatably arranged on one side of the limit plate 31. The support roller 33 can fit with the side of the photovoltaic panel. The support roller 33 fits with the side of the top of the photovoltaic panel, so that the limit plate 31 can be slidably engaged with the inclined top and bottom of the photovoltaic panel, so that the mounting plate 1 and the cleaning plate 2 can move along the linear array of the photovoltaic panels under the limitation of the two limit plates 31, so as to wipe and clean the tops of multiple photovoltaic panels.

[0029] In particular, a mounting groove is opened on one side of the limit plate 31, and a fixed shaft is fixedly connected inside the mounting groove, and the outer wall of the fixed shaft is rotatably sleeved with the limit roller 32.

The outer part of the supporting roller 33 is made of rubber material, so as to avoid it from causing extrusion damage to the top of the photovoltaic panel. The bottom of the supporting roller 33 is higher than the bottom of the cleaning plate 2, and the bottom of the supporting roller 33 is lower than the bottom of the mounting plate 1. Therefore, when the bottom of the supporting roller 33 is in contact with the photovoltaic panel, there is a certain extrusion force between the cleaning plate 2 and the photovoltaic panel, which facilitates the cleaning plate 2 to wipe and clean the top of the photovoltaic panel.

[0030] Furthermore, the connecting assembly 34 includes a fixed shell 341, a connecting plate 342 and a locking plate 343. The fixed shell 341 is fixedly connected to the end of the outer wall of the mounting plate 1, the connecting plate 342 is fixedly connected to the top of the limiting plate 31, the outer wall of the connecting plate 342 is slidably connected to the fixed shell 341, the locking plate 343 is slidably connected between the fixed shell 341 and the connecting plate 342, a sliding hole 345 is provided at the top of the fixed shell 341, the top of the outer wall of the locking plate 343 is slidably connected to the inner cavity of the sliding hole 345, an L-slot 344 is provided at the top of the connecting plate 342, and the bottom of the outer wall of the locking plate 343 is slidably connected to the inner cavity of the L-slot 344, as shown in FIG. Figure 2 As shown, when the locking plate 343 is engaged with one side of the inner cavity of the L-slot 344, the connecting plate 342 can maintain a stable connection with the fixed shell 341. When the locking plate 343 slides to the other side of the L-slot 344, the connecting plate 342 can slide and separate from the locking plate 343 through the opening of one end of the L-slot 344, thereby disassembling the limit plate 31 at the end of the mounting plate 1.

[0031] Furthermore, the top of the fixed shell 341 is fixedly connected to the connecting shell 346, the interior of the connecting shell 346 is slidably connected to the fixing plate 347, the bottom of the fixing plate 347 is fixedly connected to the locking plate 343, one end of the fixing plate 347 passes through the connecting shell 346 and is fixedly connected to the pull ring 3411, and the pull ring 3411 is used to drive the fixing plate 347 to move toward the outside of the connecting shell 346, so that the fixing plate 347 can drive the two locking plates 343 to slide, thereby releasing the clamping state of the locking plate 343 on the connecting plate 342, and the side of the fixing plate 347 The end is fixedly connected with a connecting block 348, and the interior of the connecting shell 346 is symmetrically fixedly connected with a fixing rod 349.
