It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0072] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0073] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a connection device between photovoltaic module components provided by an embodiment of the present invention includes a bracket 1. A photovoltaic panel 2 is provided on one side of the bracket 1. The photovoltaic panel 2 is slidably connected to the bracket 1 through a connection assembly 4 slidably arranged on the bracket 1. The connection device between photovoltaic module components further includes:

[0079] A power generation environment analysis unit, configured to generate a power generation condition index of the photovoltaic panel 2 according to the power generation environment data of the photovoltaic panel 2;

[0080] A start condition evaluation unit, configured to acquire the snow hardness factor on the surface of the photovoltaic panel 2, establish a start condition evaluation model, and substitute the snow hardness factor on the surface of the photovoltaic panel 2, the snow coverage index on the surface of the photovoltaic panel 2, and the power generation condition index of the photovoltaic panel 2 into the start condition evaluation model to generate a start condition index of the tilt drive assembly 5;

[0081] A start judgment module, configured to judge whether the photovoltaic panel 2 needs to perform snow removal operation according to the start condition index of the tilt drive assembly 5;

[0082] A start control module, when the photovoltaic panel 2 needs to perform snow removal operation, the start control module is configured to control the drive motor to start the tilt drive assembly 5 to work.

[0083] As Figure 1 、 Figure 2 and Figure 3 shown, as a preferred embodiment of the present invention, the connection assembly 4 specifically includes:

[0084] A lower sliding member 401, the lower sliding member 401 is slidably arranged on the bracket 1;

[0085] A lower connecting member 402, the lower connecting member 402 is rotatably arranged at one end of the photovoltaic panel 2, and one end of the lower connecting member 402 is rotatably connected to the lower sliding member 401 through a connecting shaft;

[0086] An upper connecting member 403, the upper connecting member 403 is fixedly arranged at one end of the photovoltaic panel 2;

[0087] An upper sliding member 404, the upper sliding member 404 is arranged on one side of the upper connecting member 403, and one end of the upper sliding member 404 is rotatably connected to one end of the upper connecting member 403 through a rotating shaft;

[0088] A slider 405, the slider 405 is arranged on one side of the upper sliding member 404, one end of the slider 405 is fixedly connected with one end of the upper sliding member 404, and the other end of the slider 405 is slidably connected with the bracket 1;

[0089] Specifically, by simultaneously pushing the lower sliding members 401 and 505 to perform linear motion, the lower sliding members 401 and 505 respectively drive the lower connecting members 402 and the upper sliding member 404 to perform linear motion, and the upper connecting member 403 drives the upper connecting member 403 to perform linear motion. Thus, the lower connecting member 402 and the upper connecting member 403 drive both ends of the photovoltaic panel 2 to perform linear motion, realizing the position adjustment of the photovoltaic panel 2.

[0090] As Figure 4 and Figure 5 shown, as a preferred embodiment of the present invention, the vibration assembly 3 specifically includes:

[0091] An upper buffer member 301, the upper buffer member 301 is slidably arranged on the slider 405;

[0092] An upper elastic member 302, the upper elastic member 302 is arranged on one side of the upper buffer member 301, one end of the upper elastic member 302 is in contact connection with the slider 405, and the other end of the upper elastic member 302 is in contact connection with the upper buffer member 301;

[0093] A lower buffer member 303, the lower buffer member 303 is slidably arranged on the slider 405;

[0094] A lower elastic member 304, the lower elastic member 304 is arranged on one side of the lower buffer member 303, one end of the lower elastic member 304 is in contact connection with the slider 405, and the other end of the lower elastic member 304 is in contact connection with the lower buffer member 303;

[0095] A limit block 305, the limit block 305 is fixedly arranged on the bracket 1, and one side of the limit block 305 is in contact connection with the lower buffer member 303;

[0096] A toothed chute 306, the toothed chute 306 is opened on the bracket 1, and the toothed chute 306 is toothed;

[0097] Specifically, by pushing the slider 405, the slider 405 drives the lower buffer 303 to move. When the lower buffer 303 moves to the toothed slide groove 306, since the toothed slide groove 306 is toothed, the toothed slide groove 306 causes the lower buffer 303 to reciprocate in the vertical direction during the horizontal movement along the toothed slide groove 306. Then, the slider 405 is driven to reciprocate in the vertical direction by the lower elastic member 304, thereby driving one end of the photovoltaic panel 2 to reciprocate, thereby achieving the vibration effect of the photovoltaic panel 2. At the same time, when the slider 405 performs reciprocating motion in the vertical direction, the upper elastic member 302 uses its own elasticity to keep the upper buffer member 301 always in sliding connection with the bracket 1, thereby improving the stability of the slider 405 during the motion; in addition, the elasticity of the lower elastic member 304 itself can reduce the strength of the slider 405 driven by the lower elastic member 304 to perform reciprocating motion in the vertical direction, thereby reducing the strength of the slider 405 driving one end of the photovoltaic panel 2 to perform reciprocating motion, thereby reducing the risk of damage to the photovoltaic panel 2 caused by the reciprocating motion;

[0098] In addition, when the slider 405 is reset, the inclined surface of the limit block 305 will interfere with the lower buffer member 303, thereby reducing the elastic space of the lower elastic member 304, thereby preventing the photovoltaic panel 2 from shaking.

[0099] like Figure 1 and Figure 6 As shown, as a preferred embodiment of the present invention, the tilt driving assembly 5 specifically includes:

[0100] A telescopic member base 501, wherein the telescopic member base 501 is fixedly disposed on the bracket 1;

[0104] Specifically, by starting the telescopic base 501, the telescopic base 501 drives the telescopic end 504 to perform a linear motion. The telescopic end 504 drives the crossbar 503 to perform a linear motion. The crossbar 503 drives the transmission member 502 to move, and the transmission member 502 drives the photovoltaic panel 2 to move, so as to adjust the tilt angle on one side of the photovoltaic panel 2, so that the snow on the surface of the photovoltaic panel 2 slides off due to gravity. In addition, when the transmission member 502 drives the photovoltaic panel 2 to move and adjusts the tilt angle on one side of the photovoltaic panel 2, the photovoltaic panel 2 drives the slider 405 to slide, thereby starting the vibration assembly 3, and the vibration assembly 3 drives the photovoltaic panel 2 to vibrate.
