Description

Solar Panel Cleaner {CLEANER FOR SOLAR CELL PANEL}

Embodiment of the present invention relates to a cleaning device for removing foreign matter present on the surface of the solar cell panel.

In general, a photovoltaic generator that converts light from the sun, which is one of natural energy, into electrical energy, arranges a plurality of solar cells in a horizontal and / or longitudinal direction continuously and electrically connects them to each other to generate a required power generation capacity. It includes a solar cell panel panelized to have.

The solar panel may be installed to have a fixed structure that is maintained at a set angle, or may be installed to have a tracking structure in which the angle changes depending on the position of the sun. In the case of the fixed type, the solar panel is installed horizontally, but it is common to install and use the solar panel in an inclined state to improve power generation efficiency.

One of the important factors affecting the power generation efficiency (solar energy efficiency) of the solar panel is the angle of incidence of the solar light to the solar panel. However, even if the solar panel is maintained at an optimal angle (vertical to the sunlight), if foreign matter such as dust accumulates on the surface of the solar panel, the amount of sunlight incident on the solar panel is greatly reduced, so that the solar panel Power generation efficiency is bound to decrease. Therefore, in order to maintain the power generation efficiency of the solar panel, it is also important to manage the surface of the solar panel by periodically cleaning the solar panel.

A solar panel cleaning apparatus configured to be removed is disclosed. However, such a solar panel cleaning apparatus is designed to be customized according to the size of the solar panel to be cleaned, and because it is a type fixed to the solar panel, there is a problem that cannot be used for cleaning solar panels having different sizes. have. In addition, since the brush is formed in an elongate roll type, there is a problem in that the solar panel cannot be cleaned at a uniform pressure due to a phenomenon in which the middle portion of the brush is bent during rotation of the brush.

Korean Patent Publication No. 10-1688120 discloses a solar panel cleaning robot configured to remove foreign substances from the surface of a solar panel while autonomous driving without falling off along the surface of the solar panel using adsorption force. Such a solar panel cleaning robot can be freely used for cleaning various solar panels, but since a means for adsorption force and autonomous driving control is required, the configuration of the solar panel cleaning robot is very complicated and difficult to manufacture due to sensitivity and precision. However, there is a problem that the manufacturing cost is high.

The solar panel cleaning apparatus according to the first embodiment of the present invention further includes a traveling control unit which senses the presence or absence of the surface of the solar panel 1 to limit the lateral traveling distance of the traveling module 10A. The traveling control unit controls the horizontal drive unit 16A according to the detection signal of the sensor 40 to prevent the traveling module 10A from falling off from the solar cell panel 1. The sensor 40 may be a distance sensor. The traveling control unit determines that the traveling module 10A traveling in the horizontal direction is adjacent to the surface edge of the solar panel 1 when the measured value from the distance sensor exceeds the set value, and the horizontal driving motor 161A The driving module 10A may be configured to travel in the opposite direction by stopping the operation or operating the horizontal driving motor 161A in the reverse direction. The setting value may be a value in a range including a distance from the distance sensor to the surface of the solar panel 1. The measured value exceeding the set value may be a state in which the distance sensors respectively disposed in both the horizontal directions with respect to the traveling module 10A are on the surface of the solar cell panel 1.

In addition, reference numeral 18A, which is not described in FIG. 2, is mounted on the transfer guide G1 so as to be positioned at both sides in the longitudinal direction of the transfer guide G1, and a stopper for limiting the longitudinal movement distance of the transfer module 20A. to be. According to the stopper 18A, the moving module 20A is excessively moved in the vertical direction to prevent the moving module 20A from being separated in the longitudinal direction from the conveyance guide G1.

Each of the stoppers 18A may include a stopper body 181 and a cushioning means 182 provided to the stopper body 181 to absorb shock generated when the carriage 21A collides with each other. The shock absorbing means 182 may include elastic members such as rubber and spring.
