DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] like Figure 1-4 As shown, a photovoltaic panel purge device proposed by the utility model comprises two parallel connection plates 1, and mutually parallel guide plates 2 are fixedly installed on the mutually adjacent sides of the connection plates 1;

[0025] A nozzle 3 is fixedly installed between the two connecting plates 1, and a nozzle hole is opened at the bottom of the nozzle 3;

[0026] A dust suction mechanism 4 which is rotated by the introduced gas is disposed on the connecting plate 1 , and the dust suction mechanism 4 is connected to the nozzle 3 to supply air to the nozzle 3 .

[0027] In an optional embodiment, the dust suction mechanism 4 includes a suction tube 41, an extraction fan blade 42, an auger blade 43, a rotating tube 44 and a wind-digging shell 45. The rotating tube 44 is fixedly sleeved on the middle part of the suction tube 41, and one end of the rotating tube 44 is rotatably sleeved with the connecting plate 1. The extraction fan blade 42 is fixedly installed on the outer periphery of the suction tube 41 and is fixedly connected to the suction tube 41. The auger blade 43 is fixedly installed inside the rotating tube 44. An air inlet is opened on the outer periphery of the suction tube 41, and the wind-digging shell 45 is fixedly installed at the air inlet. One end of the suction tube 41 forms an exhaust port. The rotating tube 44 is rotatably connected to a receiving tube 46 through a rotating joint, and the receiving tube 46 is fixedly connected to the nozzle 3.

[0028] Furthermore, an exhaust hood 47 is fixedly connected to the exhaust port of the suction pipe 41 . The exhaust hood 47 is rotatably sleeved with the connecting plate 1 . Exhaust fan blades 48 are fixedly installed inside the exhaust hood 47 .

[0029] It should be noted that when the suction pipe 41 rotates, the extraction fan blades 42 are driven to rotate to extract the dust gas. The rotation of the exhaust fan blades 48 extracts the gas inside the suction pipe 41 and discharges it through the exhaust hood 47.

[0030] In an optional embodiment, a filter screen 49 is connected to the exhaust end of the exhaust hood 47 via bolts.

[0031] It should be noted that the filter screen 49 is divided into two halves (consisting of two semicircular filter screens) to facilitate cleaning by disassembly through bolts.

[0032] In an optional embodiment, a roller shaft 5 is rotatably sleeved inside the guide plate 2 .

[0033] It should be noted that, under the action of the rotating shaft 5, it contacts the frames on both sides of the top and bottom of the photovoltaic panel, thereby increasing the smoothness of the movement of the entire device.

[0034] In an optional embodiment, a ball 6 is rotatably sleeved on the connecting plate 1 between the two guide plates 2 .

[0035] It should be noted that, under the action of the ball 6, it plays a role of contacting the side of the photovoltaic panel in the length direction.

[0036] In the utility model, the guide plate 2 is located at the length edge of the photovoltaic panel, which plays a guiding role. Air is introduced from the air inlet end of the rotating tube 44, and the air is ejected through the nozzle 3 to blow up the dust on the photovoltaic panel. The air enters the interior of the rotating tube 44. Under the action of the auger blades 43, the air passes through the spiral channel formed by the auger blades 43 and the rotating tube 44, thereby causing the rotating tube 44 and the suction tube 41 to rotate. The suction tube 41 rotates, driving the extraction blades 42 and the wind digging shell 45 to rotate, so as to extract the dust gas blown up by the nozzle 3, and the dust gas is discharged after being filtered by the filter net 49, thereby achieving the effect of blowing dust while filtering and collecting, and increasing the environmental friendliness of cleaning.
