JP2016030255A - Wiper for performing cleaning and snow removal of solar panel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make unattended cleaning and snow removal of a solar panel possible in accordance with changes of the seasons with extremely simple facilities although photovoltaic power generation as natural energy requires wide plottage and a large scale and it is difficult to perform maintenance such as cleaning with a manual work.SOLUTION: Two lines of guide rails are arranged from the water upper side to the water lower side, a wiper bar moving in parallel is moved from the upper part to the lower part perpendicularly to the guide rails and, thereby, the surface of a photovoltaic power generation panel is rubbed to remove staining. Therein, rain water falling on the panel is stored and is rubbed from a wiper bar with sponge as water for floating the staining. In winter while freezing does not occur as yet, a wiper for winter is moved from the upper part to the lower part and, thereby, snow removal is performed.SELECTED DRAWING: Figure 1

Description

      The present invention is in the technical field of an apparatus for cleaning and removing snow from the surface of an outdoor solar panel that is now widely used.

        The installation of solar panels started to progress due to increased distrust about nuclear power in the accident of nuclear power generation in Fukushima, and because of the recent technological advancement, the electrical conversion efficiency of solar panels increased. This is because the social infrastructure to purchase is in place. However, as the size of the solar panels increased, it was still unthinkable to clean the panels left outdoors.

Patent Publication 2014-22524 Solar Power Panel Cleaning Device

    Cleaning a large-scale photovoltaic power generation panel is very difficult to do manually. Also, in snowy countries such as Tohoku, it was impossible to generate electricity due to snow.

    It is said that the installation type solar panel has an angle of 35 degrees with respect to the ground. The solar panel is shown in FIG. A wiper bar that slides up and down at right angles is attached between them.

    As shown in FIGS. 2-11 and 14, the wiper bar has summer wiper and winter wiper attached, and when the wiper bar moves from the top to the bottom of the guide rail, the surface of the solar panel is rubbed. Dirt falls. If there is snow, you can slide it from top to bottom and drop it under the eaves.

    The wiper bar has a sponge as shown in Fig. 2-12, and the hose can be controlled by a pump according to the commands from the control box of the rainwater tank Fig. 1-6 and the detergent tank Fig. 1-5 to Fig. 1-7. It is sent to the sponge through the hole of the wiper stick and wets the surface of the solar panel, and the cleaning ability of the wiper can be enhanced.

      FIG. 2-13 is a light reflection sensor that rotates while the wiper bar returns from the bottom to the top and turns downward to detect surface contamination. The small arithmetic unit (CPU) of the control box shown in FIG. 1-7 finds a particularly severely contaminated portion, and rubs the sponge surface on which the wiper or the cleaning liquid appears several times on the solar panel to remove the dirt.

      1-4 accepts rain and cleaning liquid with rain gutters and stores the liquid in the tank of FIGS. 1-6. Thereby, even if it does not arrange | position a water pipe, wash water can be taken out independently.

      Solar panel cleaning and snow removal can be made relatively inexpensive without resorting to manual labor. However, the detergent must be refilled manually or by piping.

Claims (5)

    Install two guide rails from the surface of the solar panel down to the water, and move the rod with the wiper attached at right angles that slides up and down between them. A device that drops to the side.     In claim 1, by rotating the bar that slides up and down, the wiper for summer, the wiper for winter, spray of detergent or water that floats dust, a sensor that detects dirt on the panel surface, etc. can be directed to the panel surface. A device that keeps the surface of the solar panel clean throughout the seasons by monitoring the temperature and the amount of snow in a small control box and making appropriate judgments according to the program without relying on the hands of an administrator.     The apparatus according to claim 1, wherein the rain collecting gutter is on the underwater side, a tank for accumulating rain water is provided, and washing water can be discharged from the slide rod by a pump in summer.     The power source that operates in claim 1 is taken from a solar panel, and in addition to a small amount of detergent, the washing water uses rainwater.     2. The apparatus according to claim 1, wherein, in order to enhance the cleaning ability, the wiper rod can be rotated in addition to sliding from the top to the bottom to increase its frictional force and improve cleaning.
