[0038] During the process of lifting the photovoltaic panel, the second motor 301 drives the gear plate 305 to rotate through the rotating shaft 302, and the gear plate 305 drives the chain 303 to rotate. During the rotation of the chain 303, the photovoltaic panel can be lifted by the supporting frame 401, and the annular guide rail 304 can limit and guide the supporting frame 401 during its movement to ensure the smoothness of the lifting.

[0039] like Figure 1 and Figure 4 As shown, as an embodiment, the adjustment component 2 includes:

[0040] A support 201, wherein the support 201 is fixedly connected to the top of the support assembly 1 and is a U-shaped structure; a support frame 203, wherein the support frame 203 rotates within the support 201 and the lifting assembly 3 is installed on the support frame 203; a first motor 202, wherein the first motor 202 is fixedly connected to a side wall of the support 201 and an output shaft is fixedly connected to one end of the support frame 203.

[0041] The specific operations are as follows:

[0042] When the device is in use, the device is moved under the photovoltaic bracket on the roof, and then the first motor 202 drives the support frame 203 to rotate in the support 201 according to the inclination of the photovoltaic bracket, and then the inclination of the support frame 203 is adjusted to the same inclination as the photovoltaic bracket.

[0043] like Figure 1As shown, as an embodiment: the support assembly 1 includes: a hydraulic rod 103; the output end of the hydraulic rod 103 is fixedly connected to the middle of the bottom end of the support 201; a base 101, the base 101 is fixedly connected to the fixed part of the hydraulic rod 103; and a universal wheel 102, the universal wheel 102 is fixedly connected to the four corners of the bottom end of the base 101.

[0049] In summary, the working principle of the pulley 403 device for quickly installing photovoltaic modules on the roof is as follows: first, the device is moved to the bottom of the photovoltaic bracket on the roof through the universal wheel 102, and the external power supply is turned on. Then, according to the inclination of the photovoltaic bracket, the first motor 202 drives the carrier 203 to rotate in the support 201, and then the inclination of the carrier 203 is adjusted to the same inclination as the photovoltaic bracket. The hydraulic rod 103 can adjust the height of the carrier 203 so that the carrier 203 and the photovoltaic bracket have a reasonable height difference. After adjustment, the photovoltaic panels are stacked in the carrier frame 401, and then the second The motor 301 drives the rotating shaft 302, and the rotating shaft 302 drives the chain 303 to rotate through the toothed disk 305. During the rotation of the chain 303, the supporting frame 401 is driven to move upward, thereby realizing the lifting of the photovoltaic panel.
