[0023] The cleaning assembly 9 includes a cleaning seat 901, a cleaning motor 902 is mounted on one end of the cleaning seat 901, a cleaning threaded shaft 903 is driven and connected to one end of the cleaning motor 902, and a cleaning scraper 904 is connected to the external thread of the cleaning threaded shaft 903.

[0024] In this embodiment, as shown in Figures 1 and 3, the internal support 4 is composed of multiple ground beams and columns, and the top of the internal support 4 is set as a herringbone support structure. Furthermore, the internal support 4 is constructed by welding I-beam steel frames.

[0025] In this embodiment, as shown in Figures 1, 2 and 3, an alarm 501 is installed at the bottom center of the crossbeam 5, and a smoke sensor 502 and a temperature sensor 503 are respectively installed on both sides of the alarm 501. A remote control module is installed inside the alarm 501. Multiple cooling fans 101 are evenly installed on both outer walls of the cabin 1, and the cooling fans 101, smoke sensor 502, temperature sensor 503 and alarm 501 are all electrically connected.

[0026] In this embodiment, as shown in Figures 1, 2 and 4, the ventilation window 3 includes a window frame 301. Inside the window frame 301, a first dustproof net 302, a ventilation dustproof cotton 303 and a second dustproof net 304 are respectively installed, and the ventilation dustproof cotton 303 is located between the first dustproof net 302 and the second dustproof net 304.

[0027] In this embodiment, as shown in Figures 1, 2 and 5, the top plate 6 has a herringbone cross-section structure, and lighting equipment is provided at the bottom of the top plate 6. Both the cabin 1 and the top plate 6 are made of heat-insulating material.

[0028] In this embodiment, as shown in Figures 1, 5 and 6, there are two cleaning seats 901 in the cleaning assembly 9, and one end of each cleaning seat 901 is installed at one end of the battery base 7. Both cleaning seats 901 are located below the solar photovoltaic panel 8, and a cleaning threaded shaft 903 is rotatably connected inside one cleaning seat 901.

[0029] In this embodiment, as shown in Figures 1, 5 and 6, both ends of the cleaning scraper 904 are configured as L-shaped structures, and both ends of the cleaning scraper 904 form a sliding connection structure with the interior of the two cleaning seats 901, and the bottom of the cleaning scraper 904 is in contact with the top of the solar photovoltaic panel 8.

[0030] As shown in Figures 1, 2, 3, 4, 5, and 6, the working process of this multifunctional photovoltaic prefabricated cabin during use is as follows:

[0031] First, during the installation of the photovoltaic prefabricated cabin, the internal support 4 and the crossbeam 5 are fixed by welding, and the cabin body 1 and the top plate 6 are fixed to the internal support 4 by bolts. Then, the equipment to be integrated can be installed into the photovoltaic prefabricated cabin through the entrance and exit 2.

[0032] Subsequently, during use, the double-layer dustproof net installed inside the ventilation window 3, together with the ventilation and dustproof cotton 303, ensures internal ventilation while preventing external dust from entering the photovoltaic prefabricated cabin, reducing the impact of dust on the internal equipment. At the same time, the temperature sensor 503 inside the photovoltaic prefabricated cabin detects the internal temperature. When the internal temperature is too high, the cooling fan 101 outside the cabin 1 is activated to dissipate heat inside.

[0033] Then, when internal equipment malfunctions and produces smoke, it is detected by smoke sensor 502, and alarm 501 is activated to sound an alarm. At the same time, it notifies the handling personnel through internal remote signal transmission to handle the situation in a timely manner. In addition, the top of the photovoltaic prefabricated cabin is designed with a gable structure to prevent rain from accumulating on the top during rainy days.

[0034] Finally, when encountering heavy snow in winter, if there is too much snow on the solar photovoltaic panel 8 on the top plate 6, the cleaning motor 902 at one end of the cleaning seat 901 at the bottom of the solar photovoltaic panel 8 will start, driving the cleaning threaded shaft 903 to rotate, which in turn drives the cleaning scraper 904 to move along the direction of the cleaning seat 901, thereby causing the bottom of the cleaning scraper 904 to scrape away the snow on the top of the solar photovoltaic panel 8, so as to avoid excessive snow accumulation squeezing the solar photovoltaic panel 8 and causing damage to the solar photovoltaic panel 8.
