The utility model hinges the upper mounting plate and the lower mounting plate on the top and side of the prefabricated cabin, and the photovoltaic assembly is installed on the upper mounting plate and the lower mounting plate. The angle can be adjusted by rotating the upper mounting plate and the lower mounting plate, and the cabin body can be folded and stored during transportation, and rotated and unfolded when collecting light. This not only facilitates the transportation of the prefabricated cabin, but also improves the lighting effect and the power generation efficiency.

[0004] During the use of the above-mentioned device, as the use time increases, more and more dust and stains will adhere to the surface of the photovoltaic assembly, which will gradually reduce the photoelectric conversion efficiency and cause its discharge amount to gradually decrease. However, due to the lack of automatic cleaning measures, it is necessary to manually clean its surface, which brings inconvenience to use. At the same time, there will be great operational difficulty during manual cleaning, making the cleaning work time-consuming and labor-intensive. Therefore, in response to the above problems, a prefabricated cabin substation with photovoltaic power generation auxiliary power supply is proposed. Utility Model Content

[0028] like Figure 3 As shown, the elastic mounting frame 4 includes a transmission slide 41, and through grooves are opened at both ends of the transmission slide 41, and a sliding coupling 42 is slidably arranged in the groove. The sliding arrangement of the sliding coupling 42 can provide the necessary structural basis for the elastic mounting frame 4 to apply an elastic downward pulling force to the plate cleaning mechanism 3 as a whole. A retaining ring 43 is fixedly arranged on the upper part of the sliding coupling 42, and the connecting slide 33 is sleeved on the upper side of the sliding coupling 42 and in contact with the retaining ring 43. In addition, a locking wheel 44 is threadedly connected to the top of the connecting slide 33. After tightening the locking wheel 44, the relative extrusion force generated by it and the retaining ring 43 can clamp and fix the connecting slide 33, thereby playing a role in fixing the plate cleaning mechanism 3 as a whole.

[0029] Among them, a tensioning spring 45 is sleeved on the lower part of the sliding coupling 42, and an anti-slip end piece 46 is fixedly connected to the bottom end of the sliding coupling 42, wherein the two ends of the tensioning spring 45 are respectively fixedly connected to the transmission slide 41 and the anti-slip end piece 46. The tensioning spring 45 can apply tension to the entire panel cleaning mechanism 3, so that it can always maintain a close fit with the surface of the photovoltaic panel 2, thereby ensuring the cleaning effect of the panel cleaning mechanism 3.

[0030] In particular, when the retaining ring 43 contacts the transmission slide 41 , the tensioning spring 45 is still in a compressed state. This structural form can ensure that the tensioning spring 45 always applies tension, so that the panel cleaning mechanism 3 fits on the surface of the photovoltaic panel 2 .

[0031] like Figure 4As shown, the driving mechanism 5 includes a motor driving part 51, the output end of which is connected to a transmission screw 52, ​​and a threaded barrel 411 is fixedly provided in the middle of the transmission slide 41, wherein the transmission screw 52 passes through the threaded barrel 411 and is threadedly connected thereto. When the motor driving part 51 is working, it drives the transmission screw 52 to rotate, and drives the transmission slide 41 to move through the threaded transmission. In addition, the end of the transmission screw 52 is rotatably connected to the connecting piece on the photovoltaic panel 2. This structural form can restrain the end of the transmission screw 52, ​​so that the transmission screw 52 can remain parallel to the photovoltaic panel 2, thereby ensuring the stability of the transmission.

[0032] Among them, in order to improve the stability of the transmission slide 41 during movement, two symmetrically arranged guide rods 53 are fixed on the upper end surface of the photovoltaic panel 2, and guide cylinders 412 are fixed on both sides of the transmission slide 41, wherein the guide cylinders 412 are slidably sleeved on the guide rods 53, and can guide and constrain the sliding of the transmission slide 41 by sliding the guide cylinders 412 along the guide rods 53, thereby avoiding displacement during the sliding process.

The high-transmittance glass cover 23 replaces the photovoltaic panel 22 to withstand pollution and wear, which can significantly reduce maintenance costs.

[0034] like Figure 6 As shown, the motor drive unit 51 includes a waterproof shell 511 fixedly mounted on the support frame 21, with a drive motor 512 arranged inside the shell. The upper cover of the waterproof shell 511 is provided with a closed cover plate 513 which is tightly connected to the support frame 21. The waterproof shell 511 and the closed cover plate 513 can be combined to form a waterproof barrier to protect the internal drive motor 512 and prevent it from short-circuiting in an outdoor environment. In addition, an overhead support leg 514 is fixedly provided on the lower end surface of the waterproof shell 511. The overhead support leg 514 can raise the drive motor 512 so that water cannot directly contact it, thereby improving safety during use.

[0035] The use principle and use process of this utility model:

[0036] A photovoltaic panel 2 is arranged on the top of the prefabricated cabin body 1, and a panel cleaning mechanism 3 is provided on it. When the driving mechanism 5 is working, the panel cleaning mechanism 3 can make reciprocating motion driven by the elastic mounting frame 4 to clean the dust and stains on the surface of the photovoltaic panel 2, ensuring that the surface of the photovoltaic panel 2 will not be adhered to too much dust and stains, which will reduce its power generation efficiency.

[0037] The above process is specifically manifested as follows: when the motor drive unit 51 is working, it drives the transmission screw 52 to rotate, drives the transmission slide 41 to move through threaded transmission, and then drives the plate cleaning mechanism 3 to reciprocate. The brush layer 32 on the plate cleaning mechanism 3 is in contact with the surface of the photovoltaic panel 2. During the reciprocating motion, the surface of the photovoltaic panel 2 can be repeatedly scraped and brushed, thereby cleaning the dust and stains on its surface.

[0038] In addition, the elastic mounting frame 4 can apply a pulling force to the panel cleaning mechanism 3 so that it can always maintain a close fit with the surface of the photovoltaic panel 2, thereby ensuring the cleaning effect of the panel cleaning mechanism 3. Specifically, the tensioning spring 45 is always in a compressed state and can continuously provide a thrust to make the sliding coupling 42 slide down, thereby pulling the panel cleaning mechanism 3 installed on the sliding coupling 42 downward, so that the panel cleaning mechanism 3 is in close fit with the surface of the photovoltaic panel 2.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
