Therefore, the following detailed description is not in the sense of limitation, and the scope of the claimed subject matter is only defined by the appended claims and their equivalents.

[0030] As shown in Figure 1 and Figure 2 , a photovoltaic assembly cleaning device comprises a blowing assembly 1 and an auxiliary support assembly 2;

[0031] The blowing assembly 1 comprises a blowing main pipe 101 extending along the length direction of the photovoltaic assembly 4, which is erected above the photovoltaic assembly 4 and can reciprocate along the width direction of the photovoltaic assembly 4, the blowing main pipe 101 is provided with a blowing inlet 102 and a blowing outlet, the blowing outlet is installed with a nozzle 103, and the blowing inlet 102 is connected with an air inlet hose (not shown in the drawings);

[0032] The auxiliary support assembly 2 comprises a telescopic sleeve 201 sleeved outside the air inlet hose and a support frame 202 supported at the bottom of the telescopic sleeve 201, the telescopic sleeve 201 comprises a plurality of auxiliary branch pipes 2011 hingedly connected in sequence, the auxiliary branch pipes 2011 are hard pipes, the air inlet hose is sleeved in each auxiliary branch pipe 2011, and the auxiliary branch pipe 2011 close to the blow washing main pipe 101 is hingedly connected with the blow washing main pipe 101; a first hinge is arranged between two adjacent auxiliary branch pipes 2011, the first hinge comprises a hinge seat fixed with one of the auxiliary branch pipes 2011, and a first pin shaft is arranged between the hinge seat and the other auxiliary branch pipe 2011, and the hinge seat comprises two oppositely arranged angular support plates.

[0038] The second valve 6 and the auxiliary branch pipe 2011 close thereto are provided with a second hinge, the second hinge includes two connecting ears, a second pin shaft inserted between the connecting ears and the auxiliary branch pipe 2011, and a connecting plate connected between the two connecting ears, the connecting plate is provided with a connecting head for connecting the air inlet hose and the first air inlet of the first valve 5.

[0039] In some examples, as shown in Figure 3 The reciprocating driving mechanism 3 includes a motor 301, a motor seat 302 fixedly connected with the blowing main pipe 101 and for mounting the motor 301, and a driving wheel 303 connected with the output end of the motor 301; starting the motor 301, the motor 301 drives the driving wheel 303 to roll on the tracks 2022, thereby realizing the reciprocating movement of the blowing main pipe 101.

[0042] Working principle:

[0043] The cleaning medium (compressed air, water or cleaning liquid) enters the inner cavity of each blowing branch pipe 104 in sequence through the second valve 6, the air inlet hose, the first valve 5, the connecting pipe and the blowing inlet 102, and then is sprayed out from the nozzle 103 to clean the photovoltaic module 4. In the process, the blowing main pipe 101 can slide up and down to clean the entire photovoltaic surface of the photovoltaic module 4, and the air inlet hose moves synchronously with it. When the blowing main pipe 101 moves downward, the air inlet hose stretches, and the auxiliary branch pipes 2011 move away from each other to make the telescopic sleeve 201 stretch synchronously. When the blowing main pipe 101 moves upward, the air inlet hose bends, and the auxiliary branch pipes 2011 move close to each other to make the telescopic sleeve 201 fold synchronously.
