Description

Technical Field

[0002] Photovoltaic panels, also known as solar panels, are an emerging clean energy generation device that can convert absorbed solar energy into electrical energy. Photovoltaic is the abbreviation of solar photovoltaic power generation system, which is a photovoltaic effect of solar cell semiconductor materials.

[0003] During the use of photovoltaic panels, they need to be connected and fixed to ensure the stability of the solar panel during use and to maximize its function. During the installation of solar panels, corresponding photovoltaic panel brackets are required. Currently, most photovoltaic brackets are tripod structures. The top surface of the photovoltaic bracket is an inclined surface. The bottom of the photovoltaic bracket is fixed on a pair of foundation piles distributed front and back. The photovoltaic bracket is fixed by two supporting points, which can ensure that the photovoltaic bracket is firmly and stably fixed.

[0004] Traditional photovoltaic brackets do not have a cleaning function. As photovoltaic panels are exposed to the environment for a long time, the surface of the photovoltaic panels is blocked by foreign objects such as dust, bird droppings and particles. Accompanied by high temperature weather, it is easy to cause the current and voltage of a single battery panel in the photovoltaic module to change, causing the local temperature of the photovoltaic module to rise and produce a hot spot effect on the surface of the module, seriously damaging the operation of the photovoltaic module, thereby affecting the power generation effect of the photovoltaic panel.

During this process, the cleaning roller brush 4-4 in the cleaning device 4 rotates to clean the dust and impurities deposited on the surface of the photovoltaic panel 6. At the same time, the dust and impurities swept out are collected and processed by the fan and the dust hood 5 to prevent the cleaned dust and impurities from falling on the photovoltaic panel 6 again, thereby realizing the dry cleaning operation. After the dry cleaning operation is completed, if the surface of the photovoltaic panel 6 is still deposited with stains and impurities that cannot be removed by dry cleaning, a dry cleaning operation is required, that is, the staff holds a water spray gun or a water pipe to rinse the photovoltaic panel 6, and then starts the rotating motor 4-1 in the cleaning device 4 again, so that the cleaning device 4 moves in the opposite direction along the length direction of the photovoltaic panel 6 to be cleaned and reset. During this process, the rotating cleaning roller brush 4-4 can clean the surface of the photovoltaic panel 6 again, and then clean the loose stains impacted by the water flow, so that the cleaning is thorough, the cleaning effect is good, and the work efficiency is high.
