Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation equipment, in particular to a photovoltaic power generation equipment used in a highway isolation zone. Background Art

[0002] Highway isolation belts are usually set in the middle of highways or on both sides of highways. The warning lights on such isolation belts need to be powered by power. If additional circuits are to be laid, the construction cost will increase. In this case, the warning lights need to be powered by photovoltaic power generation equipment, which greatly improves the overall component utilization efficiency and reduces the circuit laying cost.

[0003] However, existing photovoltaic panels are used outdoors for a long time and are used alternately between rainy and sunny days. The erosion of rain and wind can easily cause damage to various components on the photovoltaic panels, causing the photovoltaic panels to fail to work properly. Even if they are not eroded by rain, their surfaces will be exposed in the wild and cause a lot of stains to adhere, which in turn leads to low power generation efficiency.

[0004] In order to solve this problem, we install protective covers around the photovoltaic panels. The protective covers can protect the photovoltaic panels from being eroded by rain and wind, but a large amount of stains will still adhere to the surface of the protective covers, blocking them, resulting in a further reduction in power generation efficiency. The warning light surface at the front end of the isolation strip will also be covered by a large amount of stains after long-term use.

[0005] In order to solve the above problems, we propose to install rotating cleaning mechanisms and transverse cleaning mechanisms to clean the isolation belt plates and protective covers, and other linkage components can be installed for simultaneous cleaning. If tap water is used for cleaning, it is necessary to install and lay water pipes, which further increases the construction cost. In order to solve this problem, rainwater filtration can be set up for recycling. In summary, we have proposed a photovoltaic power generation equipment for highway isolation belts.
