DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a building assembled photovoltaic curtain wall includes a keel 1, and also includes: a bracket 2 screwed to the front end of the keel 1; a rear frame 3 welded to the front end of the bracket 2, and a first positioning plate 4 is welded to one side wall of the rear frame 3; a front frame 5 rotatably connected to the front end of the rear frame 3; a photovoltaic panel 6 clamped between the front frame 5 and the rear frame 3; a cleaning mechanism 7 arranged on the side of the front frame 5, the cleaning mechanism 7 is used to scrape the photovoltaic panel 6; and a second positioning plate 8 detachably connected to one side wall of the front frame 5.

[0026] like Figure 4As shown, the front frame 5 includes two front vertical rods 51, a first connecting rod 52 and a bottom groove 53. The front vertical rods 51 are "L"-shaped. The front vertical rods 51 are arranged on both sides of the photovoltaic panel 6. The spacing between the two front vertical rods 51 is the same as the spacing between the photovoltaic panel 6. The front vertical rods 51 clamp the two sides of the photovoltaic panel 6 to limit the shaking of the front vertical rods 51. The first connecting rod 52 connects the tops of the two front vertical rods 51 to make the spacing between the two front vertical rods 51 fixed and more stable. The bottom groove 53 connects the bottoms of the two front vertical rods 51. The bottom groove 53 supports the bottom of the photovoltaic panel 6. The bottom groove 53 can receive part of the rainwater, reduce the falling of rainwater after contacting the dust on the photovoltaic panel 6, and reduce the impact on pedestrians passing under the curtain wall.

[0027] like Figure 5 As shown, the cleaning mechanism 7 is provided with two groups, and the cleaning mechanism 7 is arranged on the side walls of the two front vertical rods 51. The cleaning mechanism 7 includes a motor 71, a first rotating shaft 72, a cleaning brush 74 and a protective cover 73. The motor 71 is fixedly connected to the side wall of the front vertical rod 51, and the output end of the motor 71 is meshed with the first rotating shaft 72 through gears. After the motor 71 is started, it drives the first rotating shaft 72 to rotate. The cleaning brush 74 is welded to the bottom of the first rotating shaft 72. When the first rotating shaft 72 rotates, the cleaning brush 74 rotates together. The brush head of the cleaning brush 74 is made of rubber material. The cleaning brush 74 contacts the photovoltaic panel 6. The cleaning brush 74 cleans the dust on the surface of the photovoltaic panel 6 by rotating. The protective cover 73 is screwed to the front vertical rod 51. The protective cover 73 covers the motor 71 and the first rotating shaft 72. The protective cover 73 does not affect the rotation of the first rotating shaft 72 and the cleaning brush 74. The protective cover 73 prevents a large amount of water from flowing into the first rotating shaft 72 on rainy days, causing the first rotating shaft 72 to be corroded.

[0028] The cleaning brush 74 is in a vertical state when not working. When the cleaning brush 74 is in the vertical state, the bottom of the cleaning brush 74 is in the same horizontal line with the bottom of the photovoltaic panel 6. When the cleaning brush 74 is cleaning, the first rotating shaft 72 can be rotated ninety degrees to make the cleaning brush 74 in a horizontal state. When cleaning is needed, the two cleaning brushes 74 work alternately to clean most of the photovoltaic panel 6. The best working time of the cleaning mechanism 7 is light rain weather. Rainwater can be used to clean the photovoltaic panel 6 more thoroughly, so that the photovoltaic panel 6 maintains the efficiency of converting solar energy into electrical energy. It can also be cleaned in non-rainy weather.

[0029] An extension plate 711 is welded to the side wall of the motor 71 , and the first rotating shaft 72 is rotatably connected to the extension plate 711 . The extension plate 711 limits the position of the first rotating shaft 72 so that the first rotating shaft 72 can only rotate.

[0030] like Figure 3As shown, the rear frame 3 includes two rear vertical rods 31, two connecting pieces 32, a second connecting rod 33 and a bottom rod 34. The connecting piece 32 is welded to the side wall of the rear vertical rod 31. The top of the connecting piece 32 is higher than the top of the rear vertical rod 31. The front end of the connecting piece 32 is located at the side wall of the front vertical rod 51. The connecting piece 32 and the front vertical rod 51 are not connected. The second connecting rod 33 connects the tops of the two connecting pieces 32. The bottom rod 34 connects the bottoms of the two rear vertical rods 31. The second connecting rod 33 connects the two connecting pieces 32 as a whole. At the same time, the second connecting rod 33 can be used for positioning the upper curtain wall. The bottom groove 53 of the upper curtain wall is in contact with the second connecting rod 33, so that the installed curtain wall is in the same horizontal and vertical lines, which has aesthetics and integrity.

[0031] like Figure 2 As shown, a base 511 is provided on the top of the front vertical rod 51, and a second rotating shaft 512 is connected between the base 511 and the side wall of the connecting piece 32. When there is no need to replace the photovoltaic panel 6, the front vertical rod 51 and the bottom groove 53 are in a vertical state under the action of gravity. When the photovoltaic panel 6 is damaged and needs to be replaced, the operator can lift the bottom groove 53 to lift the front vertical rod 51 upward, and the photovoltaic panel 6 can be disassembled for repair or replacement.

[0032] The first positioning plate 4 and the second positioning plate 8 are both "L"-shaped plates. The first positioning plate 4 is welded to one side of a rear vertical rod 31, and the second positioning plate 8 is screwed to the front vertical rod 51 on the opposite side. The first positioning plate 4 faces the front vertical rod 51, and the second positioning plate 8 faces the rear vertical rod 31. During the building assembly, the first positioning plate 4 is hooked to the second positioning plate 8 of the adjacent front vertical rod 51 to complete the assembly of the left and right curtain walls.

[0033] A protrusion 81 is provided at the top of the rear end of the second positioning plate 8. The protrusion 81 is higher than the top of the second positioning plate 8. The rear end of the protrusion 81 is located above the first positioning plate 4. After the second positioning plate 8 is screwed to the front vertical rod 51, rotating the front vertical rod 51 upward will cause the protrusion 81 to jam the first positioning plate 4. The protrusion 81 limits the rotation of the front vertical rod 51. When the photovoltaic panel 6 needs to be replaced, the second positioning plate 8 is first removed. At this time, the front vertical rod 51 can be rotated. The limiting structure of the protrusion 81 is simple and practical, and it is convenient to disassemble and assemble.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
