Description

The present invention relates to the technical field of a photovoltaic power plant maintenance device, and specifically to a solar panel cleaning robot of a photovoltaic power plant.

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by utilizing the photovoltaic effect at the semiconductor interface. The key element of such technology is the solar cell. After being connected in series, the solar cells are package-protected to form a large-area solar cell module, and further form a photovoltaic power generation device according to parts such as a power controller. The solar power generation module converts direct sunlight into DC power, and the solar cell string is connected in parallel to the DC distribution cabinet via a DC bus box, merges and connected to the DC input end of the inverter, and the DC power is converted to AC power. The inverter AC output terminal is input to the AC power distribution cabinet and directly taken into the user side via the AC power distribution cabinet.

With the development of modern industry, the global energy crisis and air pollution problems have become apparent, conventional fuel energy is decreasing day by day, and photovoltaic power generation is being applied more and more as one of the major green energies. , The number and scale of solar power plants built are also increasing. In photovoltaic power plants, the amount of power generation cannot be controlled by human power, and cleaning the surface of the solar panel is the main guarantee of the amount of power generation, except to avoid loss due to the failure of manually controllable electrical equipment. However, this point is particularly noticeable in the presence of pollution and dust, so it is necessary and effective to clean the solar panel regularly if conditions permit. The importance of cleaning PV boards is explained below in two main points:

Impact of solar panel ash deposits on photovoltaic power plants:
When ash adheres to the surface of the solar panel as a substance with low thermal conductivity, it interferes with the heat transfer of the surface of the solar panel to the outside, the heat of the solar panel itself is not released, and the temperature of the solar panel rises. It becomes higher and higher, affecting the efficiency of photovoltaic power generation, and there is a risk of spontaneous ignition due to local overheating of the panel, that is, the "hot spot effect". The temperature effect of ash directly affects the module temperature, which affects the power output of the PV module and at the same time leads to the safety problem that the module overheats locally.
In the entire glass lid plate of the solar panel, the degree of corrosion of acidic or alkaline dust on the glass cover and the surface roughness of the glass cover due to poor cleaning increase, the reflected light energy increases, and the refracted light energy decreases. The intensity of the incident light on the solar cell is weakened, the photoelectric effect is weakened, and the amount of power generation is reduced. Although the corrosive effect of ash accumulation is small, the damage to the PV module is permanent and difficult to repair, and only to reinforce the daily accurate cleaning maintenance and maintenance is to corrode the solar panel. The harm can be minimized.

Effect of Adhesive Dirt on Photovoltaic Power Generation It is understood that the pollution of the surface of solar panels has a very significant effect on the power generation efficiency, and the principle of the effect is mainly two aspects: First, surface fouling affects the light transmittance and also the amount of radiation received on the surface of the module. Second, the dirt on the surface of the module forms a shadow because it is close to the battery cell, and the photovoltaic module forms a heat spot effect in the local area, which in turn reduces the power generation efficiency of the module and eventually burns the module. Is. If the filth on the surface of the module is a local shield such as leaves, mud, bird droppings, etc., its principle of action will be indicated as the effect of more thermal spot effects.
Conventional solar panel cleaning and maintenance equipment is mainly divided into two types in terms of its cleaning effect. The first is a simple dust cleaning (including adhesive dirt such as dust, mud, and leaves on the surface) on the surface of the solar panel, which is not a thorough cleaning. The second is that the surface of the solar panel can be washed directly with water to clean and thoroughly clean it, but when cleaning and maintaining a large range of photovoltaic power plants, a large amount of water resources are wasted. Also, it is not convenient to carry because it is necessary to connect a long external water pipe.

The brush roller 5 and the cleaning cotton roller 6 start to rotate in synchronization with the above, and the traveling motor 21 is activated. With the automatic movement of the automatic traveling mechanism 2 and the cooperation of the auxiliary traveling mechanism 3, the entire robot stands on the solar panel stand. At the same time as slowly moving at a constant speed along the upper row of solar panels, both the brush roller 5 and the cleaning cotton roller 6 roll along the surface of the solar panel, and the brush roller 5 first cleans the solar panel. That is, the dust on the surface of the solar panel and the adhesive filth such as leaves, bird manure, and mud are cleaned, and after the cleaning is completed, the surface of the solar panel is washed with the washing cotton roller 6, and the water is purified according to the rotation of the washing cotton roller 6. The cleaning cotton roller 6 that has penetrated from the liquid storage inner cylinder 61 into the cleaning cotton cover 65 and is saturated with water can realize cleaning of the solar panel, and the cooperation between the brush roller 5 and the cleaning cotton roller 6 is primary for the solar panel. Cleaning and secondary cleaning can be performed, ensuring thorough cleaning of the solar panel, and after completing the solar panel cleaning work, move the liquid storage tube head 612 again to rotate the liquid storage inner cylinder 61. The large-sized liquid leak hole 611 and the small-sized liquid leak hole 621 are completely displaced from each other to prevent water from leaking. Taken together, the cleaning robot of the present invention is capable of solar power generation.
