Dry-cleaning and water-washing hybrid solar panel cleaning device

Abstract

The invention discloses a dry-cleaning and water-washing hybrid solar panel cleaning device. According to the specific structure of the dry-cleaning and water-washing hybrid solar panel cleaning device, two driving bevel gears are arranged on a transverse shaft; two screw rods are parallel; transmission bevel gears are fixed at the front ends of the screw rods; the driving bevel gears and the transmission bevel gears are perpendicular and meshed mutually; through holes are formed in front and rear plates of a tank body; four nuts matched with the screw rods are arranged in the through holes; adriving shaft, a driving gear shaft, a water pipe and a gear shaft are sequentially fixed on left and right side plates of the tank body from front to back; friction wheels are correspondingly fixedat both ends of the driving gear shaft and the driving shaft; a strip sponge used for friction driving is arranged on the friction wheels; a rolling brush is fixed on the gear shaft; and a plurality of atomizing nozzles are fixed on the water pipe. The dry-cleaning and water-washing hybrid solar panel cleaning device disclosed by the invention is novel in structural design as well as simple and convenient to operate; the dry-wet dual cleaning process is achieved and the cleaning effect is good; the energy consumption is low and the recycling of water resources is achieved; and meanwhile, the cleaning requirements of photovoltaic panels of various sizes, heights and inclinations are met.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of cleaning mechanical devices. Background technique [0002] 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 a...

Studies have shown that solar panels that are not cleaned regularly will indirectly lead to lower photoelectric conversion efficiency

Ordinary dust can cause power generation power attenuation by up to 40%, and oily dust can cause attenuation rates as high as 60%

At the same time, dust coverage will 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

[0003] 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 their rollers will wear the surface of photovoltaic components when rotating at high speed, which will affect the performance of solar panels

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

[0004] The solar panel cleaning devices described in the above two patents are not convenient for assisting manual cleaning of photovoltaic modules
