[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In this scheme, two C-shaped clips are first inserted into two ladder frames, and the two ladder frames and two C-shaped clips are fixedly connected by bolts to realize the fixed installation of the expansion mechanism on the bottom of the main frame, and then a single power generation board is inserted between the inner walls of the auxiliary frame, so that the two hooks are inserted into the two grooves, and the insertion strip is inserted into the two hooks. By threading two fastening screws from the bottom of the two hooks, the two fastening screws are inserted into the two insertion holes of the insertion strip to realize the installation of the single power generation board, and at the same time, the motor is powered on to start, and the output end of the motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate by meshing with the driven gear, and the driven gear drives the lead screw to rotate, and the lead screw pushes the sliding sleeve to slide in the sliding rail by sliding with the sliding sleeve, and the sliding sleeve pushes the sliding sleeve to slide in the sliding rail.

[0029] 2. In this solution, during the expansion of the photovoltaic power generation assembly, after the two C-shaped card strips are plugged into the two ladder frames, the two C-shaped card strips are fixedly connected to the two ladder frames by bolts, so that the expansion mechanism can be detachably installed on one side of the main frame, so that the expansion of the photovoltaic power generation assembly has the function of quick installation and disassembly.

[0030] 3.

In winter, the single power generation panel is in a vertical state to prevent the extended single power generation panel and the extension mechanism from being damaged by snow accumulation, and at the same time, the self-locking ability of the screw and the sleeve is used to improve the wind resistance of the extended single power generation panel, and finally improve the wind resistance and snow pressure resistance of the expandable photovoltaic power generation component.

[0031] 4. In this solution, when the deflection angle of the auxiliary frame and the power generation panel is required, the output end of the electric push rod pushes the pawl to engage with the ratchet to lock the deflection angle of the auxiliary frame and the power generation panel, and cooperates with the self-locking of the lead screw and the sleeve to achieve double locking of the deflection angle of the auxiliary frame and the power generation panel, ensuring that after the two power generation panels are horizontally aligned, the power generation current of the expanded power generation panel and the original power generation panel are unified to avoid current differences during peak power generation, prevent the panel from burning, and then increase the current stability of the expanded photovoltaic power generation component.

[0064] The bottoms of the two ladder frames 3 are fixedly connected with counterweights 5 by bolts.

[0065] In the present invention, when the main frame 1 and the auxiliary frame 2 are horizontally parallel to the ground, the expansion mechanism is counterweighted by installing counterweight blocks 5 at different positions to improve the structural stability of the expanded photovoltaic power generation assembly and the original photovoltaic power generation assembly.

[0066] A gyroscope 30 is fixedly mounted on the bottom of the auxiliary frame 2 , and a control terminal 31 is fixedly connected to the bottom of the main frame 1 .

[0067] In the present invention, the gyroscope 30 is used to detect the tilt angle of the auxiliary frame 2 and the single power generation panel 25 in real time, and transmit the tilt parameters to the control terminal 31, so as to facilitate the deflection adjustment of the auxiliary frame 2 and the single power generation panel 25. The control terminal 31 adopts an integrated circuit method to integrate the storage unit, the operation unit and the signal transmission unit to support the actual power generation and operation needs of the photovoltaic power generation component.

[0068] A method for using an expandable photovoltaic power generation component comprises the following steps:

[0069] S1. Installation:

[0070] First, insert the two C-shaped clips 4 into the two ladder frames 3. The two ladder frames 3 and the two C-shaped clips 4 are fixedly connected by bolts to realize the fixed installation of the expansion mechanism at the bottom of the main frame 1. Then, insert the single power generation board 25 between the inner walls of the auxiliary frame 2, so that the two hooks 27 are inserted into the two embedded grooves 26, and the insertion strip 28 is inserted into the two hooks 27. By threading two fastening screws 29 from the bottom of the two hooks 27, the two fastening screws 29 are inserted into the two insertion holes of the insertion strip 28 to realize the installation of the single power generation board 25.

[0071] S2, flip:

[0072] When a single power generation panel 25 is installed in the auxiliary frame 2, the motor 34 is powered on to start, and the output end of the motor 34 drives the driving gear 12 to rotate, and the driving gear 12 drives the driven gear 11 to rotate by meshing with the driven gear 11, and the driven gear 11 drives the screw rod 10 to rotate, and the screw rod 10 pushes the sliding sleeve 14 to slide in the slide rail 8 by sliding cooperation with the sliding sleeve 14, and the sliding sleeve 14 pushes and pulls the first push-pull rod 16, and the first push-pull rod 16 pushes and pulls the second push-pull rod 17, and the second push-pull rod 17 pushes and pulls the two flip rods 22, and the two flip rods 22 and the connecting block 18 rotate with the shaft supporting the shaft frame 23 as the rotation support axis, and then the connecting block 18 drives the auxiliary frame 2 to deflect on the side driven by the main frame 1, so that the power generation panel 25 in the auxiliary frame 2 can be flipped;

[0073] S3, Lock Deflection:

[0074] Before the single power generation board 25 is flipped, the output end of the electric push rod 19 contracts and pulls the pawl 21, and the pawl 21 moves away from the ratchet 24, and then the locking engagement between the pawl 21 and the ratchet 24 is released, and the connecting block 18, the auxiliary frame 2, the power generation board 25 and the two flip rods 22 can be axially rotated with the shaft supporting the shaft frame 23, and the single power generation board 25 is deflected to a required angle, and the output end of the electric push rod 19 pushes the pawl 21 to engage with the ratchet 24, and the deflection of the single power generation board 25 is locked, so as to realize the locking deflection of the single power generation board 25;

[0075] S4, Real-time detection:

[0076] During the flipping process of a single power generation panel 25, the gyroscope 30 detects the deflection angle of the power generation panel 25 every 0.2 seconds, and transmits the deflection angle of the power generation panel 25 to the control terminal 31, thereby effectively controlling the deflection angle of the single power generation panel 25 and realizing real-time detection of the flipping angle of the power generation panel 25.
