The shed support 1 is provided with a chassis 11, a lifting platform 12, a telescopic lifting mechanism 13, a photovoltaic module mounting platform 14 and a telescopic mounting platform lifting device 15, so as to realize the folding characteristic of the shed support 1. Specifically:
the chassis 11 is used for supporting the shed bracket 1, and the photovoltaic module mounting platform 14 is used for mounting the solar photovoltaic module 2. The lower end side of the photovoltaic module mounting platform 14 is connected with the lifting platform 12 through a pin shaft, and then an included angle formed between the photovoltaic module mounting platform 14 and the lifting platform 12 is recorded as an elevation angle beta (shown in fig. 1) of the photovoltaic module mounting platform 14. The lifting mechanism 13 is connected above the chassis 11, the lifting platform 12 is connected above the telescopic lifting mechanism 13, and at the same time, the telescopic mounting platform lifting device 15 is connected above the lifting platform 12. The lift platform 12 and mounting platform lifting device 15 of the present invention together support the photovoltaic module mounting platform 14.
The lifting mechanism 13 includes a first hydraulic rod 131, a first support rod 132, a second support rod 133, a first guide wheel 134, and a second guide wheel 135. One end of the first supporting rod 132 is connected with the chassis 11 through a pin shaft, and the other end is connected with the lifting platform 12 through a first guide wheel 134.

And then drives the second hydraulic rod 151 to act, the third guide wheel 153 slides on the guide rail of the lifting platform 12, wherein a plurality of sensors 16 (for example, 5-8 sensors) are installed on the lifting platform 12 and are used for detecting the elevation angle beta of the photovoltaic module installation platform 14.
When the second hydraulic rod 151 is operated and the third guide wheel 153 slides, the third support rod 152 is close to the corresponding sensor 16, and when the elevation angle β of the photovoltaic module mounting platform 14 reaches the set angle, the second hydraulic rod 151 stops operating.
The adjustment range of the elevation angle beta during selection is related to an integral framework formed by mutually matching the solar photovoltaic module 2, the installation platform lifting device 15, the lifting platform 12 and the like, and the adjustment range of the elevation angle beta can be matched with the solar illumination requirement and the like required by regional conditions.
