Mobile device for washing machine of photovoltaic module {MOVING DEVICE FOR WASHING APPARATUS OF SOLAR PHOTOVOLTAIC MODULE}

The present invention relates to a moving device for a washing machine of a photovoltaic module, and more particularly, it is installed on one side of the upper surface of the panel of the photovoltaic module, and it is possible to remove foreign substances attached to the surface of the panel while moving in one direction and the other direction. In order to move the washing machine of the solar power module configured to move, it is configured to be installed on one side and the bottom of the housing so as to be able to swing, so that the washing machine of the solar power module can be moved in a stable state and can be used universally for all panels. It relates to a moving device for a washing machine of a photovoltaic module.

In general, the method of using solar energy is largely divided into a method of using solar heat and a method of using sunlight.

The method of using solar heat is to heat and power generation using water heated by the sun, and the method of using sunlight is to generate electricity using the light of the sun and operate various machines or appliances with the generated electricity. In general, the latter is referred to as solar power generation.

Among the above-described methods of using solar energy, photovoltaic power generation generates electricity using a photovoltaic effect, and the photovoltaic effect is a solar cell in which a pn junction is performed by n-type doping on a silicon crystal. When the photovoltaic panel is irradiated with sunlight, electromotive force by electrons and holes is generated by light energy.

To this end, a solar cell for condensing sunlight, a photovoltaic module, which is an assembly of solar cells, and a solar array in which solar cells are regularly arranged are required.

For example, when light is incident on the solar module from the outside, electrons in the conduction band of the p-type semiconductor are excited as a valence band by the incident light energy. One electron-hole pair (EHP) is formed inside the p-type semiconductor, and among the electron-hole pairs generated in this way, electrons are converted into n-type semiconductors by an electron field existing between the pn junctions. It passes over and supplies current to the outside.

On the other hand, unlike conventional energy sources such as fossil raw materials, photovoltaic power generation is a clean energy source that does not cause global warming, such as greenhouse gas emissions, noise, and environmental destruction, and there is no fear of depletion. In addition, unlike other wind and sea power, solar power generation facilities have the advantage of being free to install and low maintenance cost.

However, in the case of the most widely used silicon solar cell, when the temperature of the solar module rises, a decrease in output of 05% per 1℃ occurs. According to these characteristics, solar power output peaks in spring and autumn, not in summer, when the sun is the longest.

This increase in temperature is a major cause of lowering the power generation efficiency of photovoltaic power generation.

In addition, such a solar module has a disadvantage that dirt may easily accumulate on the solar panel due to meteorological phenomena such as yellow dust and bad weather.

When dirt accumulates in the solar module, the light absorption rate of the solar module decreases significantly, and as a result, power generation efficiency may also decrease.

In addition, when rain or snow falls on the solar panel in winter, power generation efficiency may decrease. In order to prevent a decrease in power generation efficiency due to such dirt, snow, rain, etc., it is necessary to periodically clean the solar module.

In recent years, there is a tendency that a lot of cleaning devices for solar panels have been developed to solve this problem.

The conventional cleaning device for a solar panel is configured with a cleaning unit that is coupled to the support panel of the solar panel and moves in a lateral direction along the support panel to clean the support panel, and the cleaning unit is the support panel. A support provided with a support wheel in close contact with the circumferential surface of the support, and a driving wheel provided on the support and in close contact with the upper surface of the support panel and driven by a driving motor to move the support in a lateral direction along the support panel, the It is provided on a support and is rotated by a driving motor to wipe off foreign substances on the upper surface of the support panel, and a spraying means provided on the support and spraying water supplied through a water supply pipe toward the solar cell.

Accordingly, while the washing unit moves to the left and right along the support panel, it is possible to wash foreign substances on the support panel.

On the other hand, when installing such solar panels, several solar panels are arranged to be spaced apart from each other in the front and rear directions.

By the way, the above-described cleaning apparatus for solar panels is configured to be able to clean the support panel while sliding in the lateral direction along the support panel of the solar panel extended in the lateral direction.

Therefore, in this way, when several solar panels are arranged to be spaced apart from each other in the front and rear directions, each solar panel must be provided with one of the above-described solar panel cleaning devices.

That is, when several solar panels spaced apart from each other in the front-rear direction are provided, there is a problem in that cost increases because several solar panel cleaning devices must be provided to correspond to the number of solar panels. .

Therefore, in order to solve this problem, a cleaning device for solar panels has been published in Patent Application No. 10-2015-0190992.

Looking at, a conventional cleaning device for a solar panel includes a support panel, a solar cell that is provided on the upper surface of the support panel and generates power when sunlight is irradiated, and the solar cell extends downward from the support panel and is fixed to the bottom surface. A cleaning unit that is coupled to a support panel of a solar panel consisting of a support frame that supports the cell inclined toward the sun and moves in a lateral direction along the support panel to clean the support panel, and a plurality of the solar panels are mutually in front and rear directions. A guide rail that is provided to be spaced apart from each other and extends in the front and rear directions to be positioned on one side of the solar panel, and a cleaning unit that is provided on the guide rail so as to be able to move forward and backward, and which is coupled to the support panel of the solar panel. A bogie is coupled to the guide rail so as to move in the front and rear direction and moves forward and backward along the guide rail, and a seating panel is provided on the bogie and a transfer means connected to one side of the support panel of the solar panel, and the bogie It is provided and includes a position adjusting means for adjusting the height and angle of the seating panel, wherein the position adjusting means is fixed to an upper surface of one side of the bogie, and at the upper end, one side of the seating panel is rotatably coupled in an up-down direction. A first telescopic mechanism for elevating one side of the seating panel, a second telescoping mechanism for raising and lowering the other side of the seating panel by hinge-coupled to the other side of the bogie and the seating panel, and the seating panel is provided on the seating panel to support the seating panel In the cleaning apparatus for a solar panel comprising a height sensing means for sensing when it is raised to a height and angle corresponding to the panel, wherein the position adjusting means receives a signal from the height sensing means, and the first and second expansion and contraction mechanisms It further comprises a control means for controlling the operation of the mounting panel, characterized in that the mounting panel is provided with a connecting member that moves back and forth toward the solar panel by a slide driving means.

However, in the conventional general solar panel cleaning device made as described above, the drive wheel is directly connected to the drive motor via an axis as described above, and the support wheel is also installed so that it is impossible to swing. There is a problem in that the driving wheel and the support wheel may be damaged when moving the stepped portion generated therebetween.

In addition, the conventional cleaning device for solar panels made as described above has a problem in that the drive wheel and the support wheel are installed in a fixed state, and thus cannot be used when the panel size is different.
