Kinds of schemes is proposed to the cleaning of large-sized photovoltaic array and develops related device, but these devices, there are at high cost, operation is not
Flexibly, the disadvantages of cleaning efficiency is lower, poor reliability, is easy to damage photovoltaic array.
Summary of the invention
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is how to provide it is a kind of can be to large size
The photovoltaic array cleaning device of the surface of photovoltaic array or photovoltaic plant progress dust processing.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions:
A kind of photovoltaic array cleaning device, including rack, rack are equipped with the cleaning that can be moved along the rack length direction
Mechanism, the both ends of the rack, which are equipped with, is able to drive the walking mechanism assembly that cleaning agency moves on photovoltaic array, described clear
The cleaning face that mechanism is contacted with photovoltaic array and the walking surface that the walking mechanism assembly is contacted with photovoltaic array are swept positioned at same
Plane or close to same plane.
This cleaning device when in use, the cleaning face contacted due to cleaning agency with photovoltaic array and walking mechanism assembly with

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing.
As shown in Fig. 1, a kind of photovoltaic array cleaning device, including rack, rack is equipped with can be along rack length side
To mobile cleaning agency 1, the both ends of rack are total equipped with the walking mechanism that cleaning agency 1 moves on photovoltaic array is able to drive
At the walking surface that the cleaning face and walking mechanism assembly that cleaning agency 1 is contacted with photovoltaic array are contacted with photovoltaic array is located at same
One plane or close to same plane.
This cleaning device when in use, the cleaning face contacted due to cleaning agency 1 with photovoltaic array and walking mechanism assembly
The walking surface contacted with photovoltaic array is generally aligned in the same plane or close to same plane, so that cleaning agency 1 and light to be cleaned
Photovoltaic array surface can effectively contact and effectively be cleaned to the dust on photovoltaic array surface, during cleaning, clean
Mechanism 1 can be moved along the length direction of rack, thus the cleaning structure can photovoltaic array surface to rack length direction into
Row cleans.
After the completion of photovoltaic array surface of the cleaning agency 1 to rack length direction cleans, walking mechanism assembly band
Dynamic cleaning agency 1 moves on photovoltaic array, so that cleaning agency 1 is moved to the photovoltaic array surface not yet cleaned, at this time clearly

The plane of travel that plane where lower ending opening when sucker 9 does not vacuumize is contacted close to walking mechanism 2 with photovoltaic array.
In this way, extracting vacuum chuck 9 out using vacuum pump 7 when being attached on the surface of installing mechanism and photovoltaic array
Interior air so that vacuum chuck 9 is tightly attached to the surface of photovoltaic array, realize between cleaning device and photovoltaic array can
By connection, when needing to be separated installing mechanism with the surface of photovoltaic array, vacuum pump 7 is filled with sky into vacuum chuck 9
Gas enables walking mechanism assembly to drive entirely so that vacuum chuck 9 slightly rises and be no longer tightly attached to the surface of photovoltaic array
Apparent motion of the cleaning device in photovoltaic array.
Due to photovoltaic array surface be glass material, using the above structure the installing mechanism of form with photovoltaic array
When surface is attached, biggish active force will not be generated to the surface of photovoltaic array, while considering each piece of photovoltaic battery plate
Can there are gap or protrusion when splicing installation, when vacuum pump 7 is filled with air into vacuum chuck 9, vacuum chuck 9 will slightly
It rises, so that walking mechanism assembly is during driving the movement of entire cleaning device, vacuum chuck 9 can be crossed well
The gap generated when splicing installation or protrusion, improve the passability of entire cleaning device.
