Description

Foreign matter stacking prevention device with output control function according to foreign matter detection

The present invention relates to an apparatus for preventing stacking of foreign substances having an output control function according to detection of foreign substances, and more particularly, minimizing unnecessary power consumption by adjusting the output amount of a drive transmission system according to the type or amount of foreign substances stacked on a target surface. The present invention relates to an apparatus for preventing stacking of foreign matters having an output control function according to detection of foreign matters so as to achieve efficient energy management.

In heavy snow areas where the amount of snow falls in the winter season is enormous, the load of snow falls in proportion to the area of the roof, so if foreign substances such as snow accumulate on the roofs of buildings in these areas, the roof cannot withstand the load and collapses. In many cases, personal damage occurred as a result of falling snow or snow accumulated on the roof.

On the other hand, the importance of the use of rainwater is being emphasized in various purposes and aspects, such as solving the water shortage problem, preventing flood damage by reducing runoff during rainfall, and securing the soundness of urban water circulation.

The rainfall pattern also shows a wide distribution from low rainfall intensity of several mm per hour to heavy rainfall of several tens of mm per hour, and it is considered as effective rainfall that can be collected and used if there is rainfall of more than 5 mm per hour.

Considering the aspect of the irregularity of rainfall, it is important in terms of applicability that the rainwater collection facility does not have any complex devices such as pumps, sensors, etc., and if it rains, it is naturally treated and collected without any separate manipulation.

On the other hand, unlike conventional energy sources such as fossil raw materials, solar power is a clean energy source that does not cause global warming, such as greenhouse gas emissions, noise, and environmental destruction, and has no fear of depletion. The photovoltaic power generation facility has the advantage of being free to install and inexpensive to maintain.

However, in the case of the most widely used silicon solar cell, when the temperature of the photovoltaic module increases, an output decrease of 0.5% per 1℃ occurs.

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 in that dirt may easily accumulate on the solar panel due to yellow dust, snow accumulated in bad weather, rainwater or soil flowing down, and the like.

When dirt accumulates in the solar module, the light absorption rate of the solar module is remarkably lowered, and thus power generation efficiency may also be lowered.

As invented from the above point of view, there may be mentioned things such as “solar power generation system having a solar module cleaning device” (hereinafter, “prior art”) of Korean Patent No. 10-1340039.

The prior art includes a sprinkler for cleaning the solar module, an air compressor for spraying compressed air for removing snow, a pump that supplies water to the sprinkler, a pollution level measurement sensor that measures the pollution level of the solar module, and snow detection. It is a structure that includes a snow sensor, a water recovery device, a control unit, and a monitoring system for.

However, the prior art has too many places requiring continuous monitoring and supervision, has a complex structure, and it is difficult to adjust the appropriate driving output in response to contamination of the surface of the solar module due to various kinds of foreign substances, such as snow or rainfall. Had its limitations.

Accordingly, the lower surface of the panel 510 forming the target surface 500 is in contact with the upper surface of each of the plurality of support bars 150 and at the same time, the first rail 110 and the first rail 110 and the first rail 110 2 Both side edge surfaces of the panel 510 parallel to the rail 120 are aligned in contact, and the upper surface of the edge of the panel 510 is locked and fixed by the upper locking piece 171.

That is, the panel 510 may be a roof finishing material such as a solar panel 510 or a sandwich panel 510.

Here, the thickness of the panel 510 may be defined by the distance between the lower surface of the upper engaging piece 171 and the upper surface of each of the plurality of support bars 150, that is, the height of the edge regulating piece 170.

Therefore, it goes without saying that it is possible to provide convenience for installation and construction in the field by making the length of the edge regulation piece 170 so as to correspond to various thicknesses of the panel 510.

Meanwhile, in the present invention, the first and

second rails

110 and 120, the support support bar 150, the spacer bracket 160, the edge regulation piece 170, the upper locking piece 171, and the first and second rack gears ( 255, 265), brush support frame 330, side cover box 610, and core cover box 620, and other parts exposed to the atmosphere are all made of aluminum, aluminum alloy, or stainless steel, so that they are all made of aluminum, aluminum alloy, or stainless steel. It is desirable to be able to use it.

As described above, the present invention has an output control function according to foreign matter detection that minimizes unnecessary power consumption and promotes efficient energy management by adjusting the output amount of the drive transmission system according to the type or amount of foreign matter stacked on the target surface. It can be seen that the basic technical idea is to provide a device for preventing stacking of foreign substances.

And, it goes without saying that many other modifications and applications are also possible for those of ordinary skill in the art within the scope of the basic technical idea of the present invention.
