technical field

The utility model belongs to the technical field of design and manufacture of cleaning mechanical devices.

Background technique

In recent years, due to the accumulation of dust and sand on the surface of solar panels in my country, the huge loss caused by the decline in the power generation efficiency of solar panels has attracted the attention of the industry. With the continuous expansion of the scale of photovoltaic power plants, the problem of cleaning the dust on the surface of solar panels protrude. Studies have shown that solar panels that are not cleaned regularly will indirectly lead to lower photoelectric conversion efficiency. Ordinary dust can cause a maximum attenuation of 40% of power generation, and oily dust can cause attenuation rates as high as 60%. At the same time, dust coverage can also cause problems such as hot spot effect, local corrosion, and insulation reduction, which will cause damage to the photovoltaic panel itself and cause huge economic losses. Therefore, cleaning of solar panels is essential. At present, the solar panels used for photovoltaic power generation in my country have a large surface area and a high height, and it is difficult to carry out cleaning work. However, most of the traditional auxiliary cleaning devices are manually washed, which consumes a lot of water resources and requires a lot of human resources. The cost is expensive and not easy to operate. Therefore, The development of dry-cleaning and water-washing mixing equipment that saves manpower and has high cleaning efficiency can better deal with the cleaning problem of solar panels.

According to the search, there are technologies related to dry and wet mixed cleaning auxiliary manual devices, such as "an automatic solar panel cleaning device" disclosed in Chinese patent application No. 201810881170.3. The device is fixed with a support, a roller, a roller and a driven wheel Such dust removal components consume a lot of energy, and when the roller rotates at high speed, it will wear the surface of the photovoltaic module and affect the performance of the solar panel. Another example is "a solar photovoltaic panel cleaning device" disclosed in Chinese Patent Application No. 201810788345.6. This device can achieve the purpose of cleaning by setting a reciprocating screw, a cleaning rod, a telescopic tube and a control valve, but the device is large and difficult to operate. The overall energy consumption is large, there is no water recycling device, the cleaning efficiency is low, and the service life is short.

The solar panel cleaning devices described in the above two patents are not convenient for assisting manual cleaning of photovoltaic modules.

This device has no motor and is simple and light. It only needs to manually turn the handle and adjust the left and right positions to control the cleaning of the photovoltaic panel in the horizontal and vertical directions.

Dry cleaning, double cleaning with water and sponge friction together guarantee the efficient cleaning of the device.

3. Low energy consumption and reuse of water resources. The atomizing nozzle in the device controls the water output, and the combination of water mist and dust can effectively reduce dust. The sponge absorbs residual water on the photovoltaic panel and uses the remaining water for subsequent cleaning. The device saves the power consumption of the traditional motor operation, and the reuse of water resources makes it suitable for solar power plants with remote locations and large-scale cleaning operations.
