Description

Solar power panel cleaning equipment

The present invention relates to a cleaning device for cleaning a photovoltaic power generation panel that generates power using solar energy, and in particular, automatically cleans the entire surface of a solar panel quickly and efficiently, and The present invention relates to a cleaning device for a photovoltaic power generation panel having a function of detecting a defective or defective portion of a panel.

Conventionally, solar power generation facilities have been operated under various installation locations and climatic conditions, and operations for performing large-scale power generation from those using small solar power generation panels for personal use etc. Many solar panels with various scales and specifications are scattered throughout the country, even those that use large-scale photovoltaic panels for industrial use.

The basic principle of photovoltaic power generation is based on the photovoltaic effect using the characteristics of semiconductors, and sunlight is used as the energy source. In other words, since an electromotive force is generated by irradiating light to the panel surface that receives sunlight, even if it is a high-performance power generation panel with high power generation efficiency, if light is blocked by adhesion of dust, Is considered to be reduced.

Moreover, a photovoltaic power generation panel is basically an assembly of a plurality of cells, and a device is devised so that a large current and a high voltage can be obtained by connecting each bundle of cells connected in series. Has been made. If there is a defective part in the cell, the power generation efficiency is greatly reduced. Therefore, cleaning of the surface of the photovoltaic power generation panel and detection of failure / failure are indispensable operations.

The applicant who is the inventor of the present invention is also the applicant of Japanese Patent Application Laid-Open No. 2014-22524. The present invention basically includes a pair of upper and lower fixed guide rails, a moving frame including a pair of left and right moving guide rails, and a cleaning body mounted on the moving frame. The basic cleaning body is a magnetic member. It can be moved up and down and left and right by a non-contact power transmission mechanism. According to this technology, the brush installed on the cleaning body of the solar panel cleaning device rotates at a constant speed to clean the solar panel. It can be automatically removed across.

According to the present invention, dirt on the photovoltaic power generation panel can be washed and removed over the entire surface of the panel, so that it is possible to prevent a decrease in power generation efficiency due to dirt. However, since the failure location cannot be visually detected even if the surface of the panel becomes visible, it is necessary to provide a method for detecting a failure / failure or a detection means.

As a method of detecting failure / failure points of photovoltaic panels, we focus on the heat generation temperature of the photovoltaic panel while checking the decrease in the amount of power generation, comparing failure / failure points with other parts. Therefore, it has been found that the method of detecting the part as a failure point is worth considering as a more steady method than controlling the electric system in a complicated manner. According to this method, it is possible to surely find a failure location cheaply and easily than a device that monitors the power generation amount of each panel.

However, if the surface of the photovoltaic power generation panel is dirty, it becomes difficult to accurately detect the failure location. Further, even if a hot part is found, there is a problem that it is difficult for a repair worker to accurately recognize which part of the photovoltaic power generation panel is a failure part when repairing.

Therefore, while eliminating the above problems, cleaning the surface of the photovoltaic power generation panel and scanning / detecting the failure / failure location makes it easy to replace the failure of the photovoltaic power generation panel. There has been a demand for the development of a cleaning device for a photovoltaic power generation panel that can detect the location and accurately grasp the failure location.
