The protection casing 9 includes two mounting brackets 91 at both ends about mounting plate 1 fixed mounting, the inner chamber of mounting bracket 91 is rotated and is installed swing branch 92, has linked firmly transparent cover plate 93 between two swing branch 92. In rainy and snowy weather, the two transparent cover plates 93 can be turned oppositely and combined together to form a top plate, so that all the photovoltaic panel assemblies 29 are protected, and the photovoltaic panel assemblies 29 are prevented from being damaged by rain and snow.

Buffer unit 11 is including welding on mounting plate 1 and the open shell 111 of front side, the inner chamber of shell 111 is connected with a plurality of springs 112, and the elasticity sum of each spring 112 is less than reset spring 211's elasticity, and the front end of each spring 112 has linked firmly movable block 113 jointly, and when spring 112 was in the natural telescopic state, shell 111 was stretched out to movable block 113's front end. When the photovoltaic panel assembly 29 touches the movable block 113, the movable block 113 slides towards the inner cavity of the shell 111, so that the spring 112 is compressed, the self elastic force of the spring 112 is buffered, and the photovoltaic panel assembly 29 is protected from being damaged due to violent collision.

The invention also provides an implementation method of the automatic unfolding type photovoltaic panel self-cleaning solar power generation equipment, which comprises the following steps:

s1: unfolding the photovoltaic panel assembly 29:

starting a servo motor I3, driving a take-up and pay-off roller 4 to rotate by the servo motor I3, taking up and pay-off roller 4 to take up each main cable 27, driving two auxiliary cables 24 connected with each main cable 27 to synchronously move, driving a photovoltaic panel assembly 29 to overcome the elasticity of a return spring 211 by the auxiliary cables 24 through a pull ring 210 and rotating around an installation support 28 until the end part of the photovoltaic panel assembly 29 is abutted against a fixed frame 21, and then closing the servo motor I3, so that the photovoltaic panel assembly 29 is unfolded;

s2: cleaning of the surface of the photovoltaic panel assembly 29:

pressing the pressing block 874, driving the end part of the positioning pin 872 to move out of the tooth grooves of the gear 83 by the pressing block 874, releasing the limit on the gear 83, then rotating the handle 86, driving the rotating shaft 82, the gear 83 and the cleaning brush 85 to synchronously rotate by the handle 86, enabling the cleaning brush 85 to rotate to the cleaning station, then loosening the pressing block 874, resetting the second torsion spring 873 and driving the positioning pin 872 to synchronously reset, enabling the end part of the positioning pin 872 to be clamped into the tooth grooves of the gear 83, limiting and fixing the gear 83, and enabling the cleaning brush 85 to be kept at the cleaning station;

the servo motor II 6 is started, the servo motor II 6 drives the threaded screw rod 7 to rotate, the threaded pipe 10 moves rightwards along the threaded screw rod 7, the cleaning assembly 8 moves synchronously along with the threaded pipe 10, the cleaning brush 85 in the cleaning assembly 8 is attached to the surface of the photovoltaic panel assembly 29, the cleaning brush 85 can clean the surface of the photovoltaic panel assembly 29 along with the movement of the threaded pipe 10, the servo motor II 6 can rotate forwards and backwards for multiple times according to the using condition, the surface of the photovoltaic panel assembly 29 can be cleaned repeatedly, the operation is convenient and rapid, time and labor are saved, the surface of the photovoltaic panel assembly 29 can be kept clean all the time, the power generation efficiency is improved, and the photovoltaic panel assembly 29 can be protected from being damaged;

s3: after the surface cleaning of the photovoltaic panel assembly 29 is completed, the cleaning assembly 8 is reset:

the servo motor II 6 rotates reversely, the threaded pipe 10 moves leftwards along the threaded screw rod 7, the cleaning assembly 8 synchronously moves leftwards along with the threaded pipe 10 to an initial position, and the next cleaning operation is waited;

s4: when extreme weather (such as hail) is met, the photovoltaic panel assembly 29 is turned and folded:

the servo motor I3 rotates reversely and drives the take-up and pay-off roller 4 to rotate reversely, the main guy cable 27 is loosened, so that the auxiliary guy cable 24 is loosened, the photovoltaic panel assembly 29 gradually rotates reversely around the mounting support 28 under the reset action of the reset spring 211, after the photovoltaic panel assembly 29 contacts the movable block 113, the reset spring 211 pushes the photovoltaic panel assembly 29 to overcome the elasticity of each spring 112 to push the movable block 113 to the outer shell 111, so that the photovoltaic panel assembly 29 continues to rotate until the end part of the photovoltaic panel assembly 29 is abutted against the outer shell 111, when the end part of the photovoltaic panel assembly 29 is abutted against the outer shell 111, an included angle of 30 degrees is formed between the photovoltaic panel assembly 29 and the mounting base plate 1, at the moment, the working face of the photovoltaic panel assembly 29 faces inwards, so that the photovoltaic panel assembly 29 is prevented from being damaged due to factors such as external weather, the maintenance cost is reduced, the reset speed of the photovoltaic panel assembly 29 is controlled by the loosening speed of the main guy cable 27, the resetting speed of the photovoltaic panel assembly 29 is not too fast, so that the photovoltaic panel assembly 29 can be protected, and the photovoltaic panel assembly 29 is prevented from being damaged due to impact; after the extreme weather is released, the step S1 is repeated to restore the photovoltaic panel assembly 29 to the working state.

The technical features disclosed above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the purpose of the invention, so as to achieve the purpose of the invention.
