Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic curtain walls, and more specifically, to a split photovoltaic curtain wall structure. Background Art

[0002] As a building wall beautification device, photovoltaic curtain wall can not only effectively beautify the exterior walls of buildings, but also absorb solar energy, slow down the wall temperature and the temperature inside the building, reduce the air-conditioning load, reduce air-conditioning energy consumption, and generate electricity through the absorbed solar energy, thereby achieving the effect of energy conservation and emission reduction.

[0003] Some existing photovoltaic curtain wall structures use a support frame installed on the wall, and the photovoltaic panels are directly installed on the support frame for use. However, due to the high dust content in the outdoor environment, the dust is easily accumulated on the surface of the photovoltaic panels during long-term use. In addition, the photovoltaic panels are installed on the walls of the buildings, which makes it inconvenient to clean the dust on the photovoltaic panels, resulting in a reduction in the power generation of the photovoltaic curtain wall.

[0004] In order to solve the above problems, the present application provides a split photovoltaic curtain wall structure. Summary of the invention

[0014] Furthermore, U-shaped blocks are provided on both the left and right sides of the installation block, and a rotating rod is rotatably installed in the U-shaped groove on the U-shaped block.

[0021] Furthermore, a plurality of plug-in grooves are provided on the rear back side of the mounting plate, and the length, width and height dimensions of the plug-in grooves are the same as those of the scraper, and a plurality of sponge plates are provided on the rear back side of the scraper.

[0022] Through the above technical solution, the sponge board can effectively remove dust from the surface of the photovoltaic panel, and the sponge board can prevent the scraper from being too hard, which may cause the photovoltaic panel to be scratched.

[0023] Furthermore, a limit baffle is fixedly mounted on the front end surface of the U-shaped block, and the limit baffle is movably fitted to the right side wall of the connecting plate.

[0024] Through the above technical solution, it is convenient to limit the rotation of the second rotating motor through the limit baffle on the connecting plate during use, so as to avoid excessive rotation of the second motor, which causes the scraper to be unable to fit on the surface of the photovoltaic panel to clean the surface of the photovoltaic panel.

[0025] In summary, this application includes the following beneficial technical effects:

[0026] By controlling the rotation of the rotary motor, the rotating screw is driven to rotate, so that the translation block moves translationally on the outer wall of the rotating screw and the cross bar, so that the scraper removes the dust on the surface of the photovoltaic panel, avoiding the inconvenience of cleaning the dust on the photovoltaic panel because the photovoltaic panel is installed on the wall of the building.

[0027] By rotating the motor to drive the rotating shaft to rotate, the L-shaped connecting plate is driven to rotate and fit against the surface of the shielding belt, thereby avoiding excessive gap between the shielding belt and the front end side wall of the fixed frame, resulting in the shielding belt being unable to provide shielding protection for the cross bar and rotating screw, causing the rotating screw and the cross bar to easily rust and cannot be used normally, that is, the translation block cannot move translationally.

[0028] The second rotating motor can drive the bending rod and the scraper to rotate and fit the fixed frame, thereby reducing the wind resistance on the scraper and preventing the scraper from being blown off by the wind in strong wind weather, thereby preventing safety hazards.
