Background technique

In recent years, with the continuous expansion of the scale of photovoltaic power plants in my country, the problem of cleaning the dust on the surface of solar panels has become increasingly prominent. According to NASA research, only 4.05 grams of dust per square meter will reduce the proportion of solar energy converted to electricity by up to 40%. Great adverse effects, so it is particularly important to clean the surface of solar panels regularly. However, most of my country's photovoltaic power stations are built in remote areas with relatively harsh natural environments, where there are many dusty weather, and they are far away from water sources, precipitation is scarce, and groundwater is scarce. Using conventional water washing will face the disadvantage of difficult water supply. Therefore, the development of high-efficiency and energy-saving dry cleaning equipment The cleaning problem of large-scale photovoltaic modules can be better handled.

Cleaning process:

Place the dust-cleaning mechanism on the solar panel, and when the handle is manually pushed, the power wheel rotates to drive the first transmission shaft to rotate, thereby turning the large pulley, and the large pulley drives the small pulley through the synchronous belt meshing to realize the rotation of the roller brush shaft and the rotation of the roller brush Clean the solar panel for the first time; at the same time, the large gear on the first transmission shaft rotates the pinion through meshing transmission, thereby realizing the rotation of the second transmission shaft, and drives the disk brush to rotate through the meshing movement of the driving bevel gear and the driven bevel gear , to clean the solar panel for the second time, and at the same time, the fan in the box provides suction to suck the dusty air into the box.

Dust removal process:

After the fan is started, the air in the fan is discharged at high speed, and the air in the moving trolley box is continuously replenished into the fan, so that a higher pressure difference will be formed with the outside world. The dust from the flat suction nozzle is sucked into the suction part along with the air. When the dust-containing gas passes through the high-voltage electrostatic field, the negative ions generated by the dust particles and the cathode plate are combined with negative charges, and after the coarse filtration of the filter plate, they tend to discharge and deposit on the surface of the anode plate. .

Compared with prior art, the beneficial effect of the present invention is:

The dust-cleaning mechanism adopts gear transmission and belt transmission to provide power to the brush, which saves the installation of the motor, greatly reduces the weight of the mechanism, is easy to operate, and does not damage the surface of the solar panel, which is very suitable for manual cleaning;

2. High cleaning efficiency. This device adopts double cleaning, which can play a very good cleaning effect on the deposited dust on the surface of the solar panel. At the same time, the flat suction nozzle provides suction to suck away the dusty air and prevent secondary dust;

3. Low energy consumption, no waste of water resources. This device adopts dry cleaning method, no waste of water resources, very suitable for remote areas far away from water sources, and the cleaning dust mechanism uses a transmission device to convert manpower into power, eliminating the need for motor installation, saving energy consumption of the motor, and electrostatic dust removal The energy consumption of the device and the centrifugal fan is low, so as to achieve the purpose of saving energy;

4. The job lasts. Compared with traditional vacuum cleaners that filter dusty gas through filter bags, this device uses a new type of electrostatic precipitator to remove dust, which has high dust removal efficiency, does not need to be cleaned frequently, and does not affect the air volume at the suction nozzle, and can work efficiently for a long time.

Therefore, the device is suitable for cleaning of solar panels.
