Background technology
Requirement with environmental protection and the lifting of sustainable energy demand, the proportion of clean energy resource accounts for the ratio of total energy year by year
Lifting, the cleaning demand of photovoltaic module progressively heats up.
Photovoltaic array cleaning has two reasons：First, dirt can lead to photovoltaic plate surface to produce heat conduction difference, ultimately causes
" hot spot ", damages photovoltaic module；2nd, dirt leads to photovoltaic panel surface transmission rate to reduce, thus affecting photovoltaic panel assembly array
Photothermal conversion rate, that is, reduce generating efficiency.Therefore do not decline to ensure generating efficiency, it is to avoid photovoltaic module damages, photovoltaic panel
Cleaning is necessary.
In prior art, typically using semi-automatic cleaning, cleaning machine on main inclusion ground washing car and plate.Wherein,
The chassis of ground washing car is identical with mini-excavator, and mechanical arm configuration is also similar to the arm of digging machine, and two track drive are advanced；
Cleaning is completed by the round brush of mechanical arm tail end, can spray water in cleaning process.For the cleaning Vehicle of bottom surface, have the disadvantages that：
(1) travel speed is slower；2) cleaning operation is complicated, operator is required higher, needs while traveling between photovoltaic plate array
Pay close attention to the situation that cleaning round brush is contacted with photovoltaic plate face, cleaning Vehicle will keep constant with the distance of photovoltaic module, otherwise, cleaning
Brush cannot cover whole photovoltaic plate face height, lead to omit cleaning surface；(3) road pavement requirement is higher, when there is hole on road surface
During the section of depression, when particularly crawler belt corresponding ground in both sides has difference in height, car body can be led to sidewinder, now original and minute surface keeps flat
Angle of arrival deviation between the round brush of row and photovoltaic panel；(4) ground washing car is furnished with driver's cabin, is carried out appointing by pilot steering
Business, it is desirable to have the personnel of excavator driving experience, and, chassis is driven by internal combustion engine, needs hand oiling, cleaning way water
Amount is larger, and water tank volume is limited, needs manually repeatedly to add water in cleaning process, and less, the time that back and forth adds water is long, clearly for chassis speed
Wash efficiency to reduce again.
In addition, for cleaning robot on plate commonly used in the prior art, it carries driven in translation, power supply and cleaning
The structures such as round brush, directly in photovoltaic panel, movement is carried out simultaneously, can dry-clean；If photovoltaic panel has done volume between string and string
After outer connection guide rail transformation, board cleaning machine can be realized changing plate cleaning between string.However, on plate cleaning robot have following
Several shortcomings：(1) on plate, cleaning robot can only work on single string plate, only make extra track connection between string and string
Retrofit work after, just can carry out the cleaning across string, and even so, cleaning robot nor complete inter-bank on plate
Operation, therefore often row photovoltaic panel is at least equipped with a cleaning robot；(2) if landform does not allow all to connect between string and string
(in single file, hypsography is larger, and hill climbing demands are higher), then single file photovoltaic panel needs more than one board cleaning machine；(3) cleaning machine
Device people needs from charged pool or charged pool plate, and vehicle body is heavier, and climbing capacity and overall travel speed be not high, therefore separate unit machine
The cleaning efficiency of device people is relatively low, and the landform requirement to arrangement photovoltaic plate array is higher.Therefore, a photovoltaic array will be accomplished entirely to cover
The clean range of lid, needs cleaning robot people's quantity on the plate putting into be larger, this data directly with photovoltaic DC field
Capacitance is directly proportional, and this will lead to the cost input of the fixing cleaning equipment of writing, cleaning robot on large batch of plate simultaneously
The workload of regular maintenance is also than larger.In addition, the fault rate of batch device rises, once failed machines cannot shift in time,
" hot spot effect " will burn monolithic photovoltaic panel, can lead to whole array that fire occurs when serious.
Therefore, how to improve the plate efficiency of changing of photovoltaic module cleaning device, improve the endurance of cleaning device simultaneously, be
The current technical issues that need to address of those skilled in the art.

Aqueous solution, Clean- gases at high pressure etc.；Once cleansing medium increased, cleaning way can also increase, such that it is able to root
According to being actually needed the selection carrying out targetedly cleaning way.
Specifically, the cleaning model of following several types can be included：
1st, water cleaning
Water cleaning is the Main Means of photovoltaic panel cleaning all the time, is also relatively effective means, but sends out with photovoltaic
The increase of electric area, the shortage of water resource, and coarse water cleaning way, have resulted in water cleaning way cost big, to ring
Border impact is big, puts into the disadvantages such as manpower is many；And mentioned in background above, ground type cleaning Vehicle roller brush 2 combines the clear of water spray
Wash mode, often due to car body changes because of hypsography, lead to the end roller brush 2 of mechanical arm to rock seriously, directly crash photovoltaic
Plate, therefore, such cleaning equipment all occurs in that in being applied multiple times the accident damaging photovoltaic panel occurs；And on plate cleaning machine because
The reason scale of construction, water cannot be carried at all to clean, that is, allow to mix water tank, cleaning area is also very limited amount of, therefore at present
On plate on market, cleaning machine only has single roller brush 2 dry-cleaning pattern.
The present embodiment will be external for the water tank of cleaning machine on plate, is arranged on ground moving device, will be cleaned by flexible duct

, as traditional cleaning formulations, roller brush 2 is as the special method clearing up stain for high pressure gas flushing；Rigidity can be selected
Larger, i.e. harder bristle, after high pressure gas flushing, on plate, cleaning machine finds depositing of stain by minute surface detection meanss
Can rested near stain by cleaning machine on host controller commander's plate, open roller brush 2, stain is carried out
Targeted elimination；This cleaning way is relatively suitable for water resource and lacks or winter, and spot type is more single, does not have the feelings such as greasy dirt
Condition.
B. air purge+washing
This mode has been applied in automobile washing industry, micro- water cleaning of being known as；Carried by gases at high pressure
Atomization particle water, imitates stormy form, first send water to hit photovoltaic panel minute surface with wind, particle water is arrived with certain velocity shock
Can tile after minute surface and come, the process that water droplet launches is exactly the process adsorbing dust, will wrap up in dirt by follow-up air-flow more afterwards
The small mud point of soil and moisture blows away, thus reaching the purpose of cleaning；The impact that this mode air-flow instead of water under high pressure is made
With, go dissolving, sweep along dust spot using small part water, accomplished the cleaning of micro- water, reduce while water resources consumption it is ensured that
Cleaning performance.
C. washing+dry brush
The principle of this mode is similar with " air purge+washing ", and only " air purge+washing " is used for carrying the handss of mud point spot
Section is high pressure draught, and this method is to shift the spot after cleaning on minute surface through water with the mechanical system of scraping article or brush.
