When the device works, the anode of a high-voltage power supply is connected to the lower pole plate, the cathode of the high-voltage power supply is connected to the upper pole plate, a power switch is turned on, and the control module of the stepping motor controls the controllable guide rail to move the upper pole plate to clean sand and dust on the surface of the photovoltaic panel from top to bottom.

The performance analysis procedure of this example is as follows:
(1) Particle trajectory analysis
The influence factors on the actual particle trajectory are complex, the embodiment only analyzes the simplified model, and reasonably estimates the overall motion trend of the particle flow by applying the model.
The embodiment analyzes the trajectory of the bouncing particle under the following notation convention and simplifying assumptions (see fig. 4, in which a polar coordinate system and a rectangular coordinate system are drawn in fig. 4 at the same time):
the electric quantity of the sand is Q; the initial velocity of the sand is
The direction is vertical to the photovoltaic panel; the inclination angle of the photovoltaic panel relative to the ground is theta 0 (ii) a The inclination angle of the upper polar plate relative to the photovoltaic plate is psi 0 (ii) a The potential difference between the plates is
The forces to which the particles are subjected are gravity and electric forcesThe interparticle interactions and air drag forces are neglected.
As can be seen from the simulation effect chart (as shown in FIG. 5), the edge effect of the inclined upper plate near the solar panel is very strong, and the local strong electric field is favorable for removing the sand and dust particles with strong adhesion.
To simplify notation, in the following discussion, vectors are all represented by their right angle components. The electric field strength in a polar coordinate system is converted back to a rectangular component representation:
the gravity acceleration is:
according to newton's second law:
namely that
Two differential equations are obtained respectively:
order to
a＝gsinθ 0 ,b＝gcosθ 0 The second order constant of the following coupling is obtainedDividing into an equation set:
the particle trajectories were plotted using a numerical solution, which concluded that the lateral displacement of the particles was negligible relative to the longitudinal displacement. Thus, the sand particles will bounce perpendicular to the photovoltaic panel up to the upper plate (see fig. 6). The inclined electrode structure adopted by the embodiment can better utilize the rebound effect to increase the dust removal efficiency relative to the parallel electrode plates. One end of the inclined upper polar plate close to the lower polar plate has larger electric field intensity than that of the parallel polar plate (see figure 5), a clear clearing line can be formed in the dust removal process, the clear clearing line moves along with the movement of the upper polar plate, and the dust removal effect can be better when the dust removal line faces to sand dust with larger adhesion.
(2) Working mode optimization
In this embodiment, a pre-experiment is performed first under the condition that the photovoltaic panel is placed on a horizontal plane and inclined at a small angle (the selected panel pitch is 2.7cm and is greater than the capacitor breakdown distance) and the sweeping efficiency =1- (quality after sweeping/quality before sweeping) is defined to obtain two tables (table 2 and table 3) shown below, where table 2 is the efficiency comparison of two types of upper plate types under the condition that the photovoltaic panel is inclined by 0 ° with respect to the ground, and table 3 is the efficiency comparison of two types of upper plate types under the condition that the photovoltaic panel is inclined by 11 ° with respect to the ground.
TABLE 2
TABLE 3
From the above table experiment results, the angle change of the solar panel (photovoltaic panel) relative to the ground, the angle change of the upper polar plate relative to the solar panel, and the like all affect the cleaning efficiency.
In this test, in order to study the influence of the inclination angle of the upper plate with respect to the solar panel on the cleaning efficiency, the expression "inclined plate" and "parallel plate" are used for distinguishing, and both the inclined plate and the "parallel plate" are the upper plate.
Based on the experiment, the influence of the following factors on the dust removal efficiency is explored:
1) Angle of upper and lower polar plates:
firstly, the method comprises the following steps: the dust removal efficiency of the upper polar plates of the two types of plates is rapidly increased along with the increase of the inclination angle of the solar panel;
secondly, the method comprises the following steps: inclined panels have a clear advantage over parallel panels when the solar panels are inclined to the ground at an angle of less than 20 deg..
Thirdly, the method comprises the following steps: the dust removal efficiency of the inclined upper polar plate is obviously improved relative to that of the parallel upper polar plate, and the dust removal efficiency of the inclined upper polar plate is increased along with the increase of the polar plate angle in a certain range.
Because the lower polar plate is spread on the upper surface of the solar panel, the inclination angle of the solar panel is the inclination angle of the lower polar plate, and the inclination angle of the solar panel and the ground is the inclination angle of the lower polar plate and the ground.
2) Average plate distance:
in this embodiment, the breakdown voltage is measured by an experiment, the distance between the upper and lower polar plates is gradually increased and cleaned once, and the efficiencies corresponding to the parallel upper polar plate (parallel plate for short) and the inclined upper polar plate (inclined plate for short) are recorded to obtain table 4, where table 4 is a comparison of the efficiencies of two types of upper polar plate types when the photovoltaic plate is inclined 35 degrees with respect to the ground.

The efficiency of the two plate types can reach more than 90% when the distance between the upper and lower polar plates is smaller;
the inclined plate cleaning efficiency is higher than the parallel plate at a distance ensuring no breakthrough and the time difference is significant at larger distances (≧ 3 cm).
3) The motor advancing speed:
the experiment is carried out with a certain gradient, and the numerical results obtained show that:
along with the increase of the advancing speed of the stepping motor, the dust removal efficiency is reduced;
when the moving speed of the stepping motor is 15r/m and is converted into 0.4860cm/s, the cleaning efficiency can approach 100 percent.
Therefore, the following optimized operation mode is finally obtained:
when the inclination angle of the photovoltaic panel relative to the ground is 35 degrees, in order to enable the dust removal device to work with high efficiency, the electrode moving speed is controlled to be below 0.5cm/s, and the average electrode distance is controlled to be about 2.5 cm.
The application provides a pair of no water automatic dust collector of desolate and boundless environment photovoltaic board, the economic benefits analysis is as follows:
the applicant researches and discovers that the sand and dust accumulation amount of the photovoltaic panel is positively correlated with time, and the sand and dust accumulation amount can be accumulated to be 8g/m < 2 > on a time scale of one month. The ash amount on the surface area of the photovoltaic panel reaches 4g/m 2 The power generation efficiency is reduced by about 15-25%; if a manual cleaning mode is adopted, cleaning should be performed once every month, and the generating efficiency of the photovoltaic panel is reduced by 15% on average; and because the design optimization scheme of the photovoltaic panel is low in energy consumption, a single photovoltaic panel only needs to operate for 370s under the power of 0.127kW for cleaning, and the power consumption is only 0.013 degrees, the scheme can realize the self-power-generation cleaning of the photovoltaic panel every day, extra energy supply is not needed, and the power generation efficiency of the photovoltaic panel is maintained to be more than 99%.
In this embodiment, economic benefit = profit-cost; assuming that the efficiency of power generation is directly proportional to the yield; the income part is as follows: the power of the photovoltaic panel in unit area is 140-150W, the average sunshine in desert area is 10 hours, and 1.4-1.5 degrees electricity is generated, so the theoretical average daily yield of the photovoltaic panel in unit area is 1.45 multiplied by 0.59=0.86 yuan; and the total yield is reduced by 15% due to the time interval of manual cleaning, and the actual daily average yield of the manual cleaning is =0.86 × 85% =0.73 yuan/m 2 (ii) a Actual daily average yield =0.86 × 99% =0.85 yuan/m after optimization 2 . Cost part: the cost of the artificial cleaning photovoltaic panel is 0.4 yuan/m 2 (ii) a The average price of electricity per degree of residents in China is 0.59 yuan, the optimized unit area cleaning power consumption is 0.013 DEG, and the optimized cleaning photovoltaic panel cost is 0.008 yuan/m 2 (ii) a Considering 1m after production 2 The specification of ITO glass is about 75 yuan, the guide rail equipment is 30 yuan, and the initial total cost is 105 yuan/m 2 。
In conclusion, the annual accumulation rate k of the economic benefits of manual cleaning 1 = (0.73 × 360) - (0.4 × 12) =258 yuan/year · m 2 (ii) a Optimization scheme economic benefit annual accumulation rate k 2 = (0.8-0.008) × 360=303.12 yuan/year · m 2 (ii) a The manual cleaning scheme has no initial cost, and the initial cost of the optimized scheme is 105 yuan/m 2 . Obtaining an economic benefit curve:
P＝kT-C；
wherein P is the unit area accumulated economic benefit, k is the annual economic benefit accumulation rate, T is time, and C is the initial cost.
Comparing the manual cleaning and the optimized scheme, the accumulated economic benefit of the optimized scheme of the application is equivalent to that of the manual cleaning scheme after 2.3 years, but the transportation cost of the washing water is considered in practical application, and the cost is difficult to estimate in theory and should be practically dominant. Obviously, transport water resource can consume a large amount of manpower financial resources to the desert, increases the cost of artifical cleaning scheme, consequently in practical application, this scheme can be superior to artifical cleaning scheme in 2.3 years. 8500 kilowatt (8.5 hundred million square meters) solar projects in desert regions in China have already been worked and constructed, if the optimization scheme is completely applied, the economic effect brought after three years is 10 hundred million orders, and after four years, the total economic benefit is very obvious.
