Background technology

Desert photovoltaic generation form, the solar energy resources enriched using desert area, makes vast desert turn waste into wealth, no Preventing and fixing sand can only be played a part of, and regional economy sustainable development can be promoted.

But it is due to that photovoltaic module is arranged in desert, the dust storm in desert is more, often makes to cover on photovoltaic module More dirt is husky, so that photovoltaic module can be influenceed to receive the degree of solar energy, and then influences the generating capacity of photovoltaic module.

Utility model content

The purpose of this utility model is to provide a kind of purging system applied to photovoltaic module, and it can clean photovoltaic module On dirt it is husky.

Above-mentioned technical purpose of the present utility model technical scheme is that：One kind is applied to photovoltaic group The purging system of part, including photovoltaic module, power module and dedusting module, the dedusting module include drive module and cleaning Device, the drive module includes walking module and control module, and the walking module includes slide rail, and the slide rail is set Sliding, which is connected with sliding block, the slide rail, in the both sides of photovoltaic module, the slide rail is rotatably connected to screw rod, the screw rod It is threadedly coupled through sliding block and with sliding block, the photovoltaic module is equipped with motor, turn of the motor in the side of two slide rails Axle be connected with screw rod and with screw coaxial rotate, the cleaning device be arranged between the sliding block on two slide rails and with photovoltaic group Part is contradicted, and the control module includes：

Starting switch, the starting switch is used for output services signal；

First timing means：Starting switch is coupled to, and exports in response to working signal consecutive intervals the height of a period of time Level signal and low level signal；

Second timing means：The low electricity continued for some time is exported first in response to the high level signal of the first timing means Ordinary mail number, and then output continues the high level signal of phase same amount of time；

Switching circuit, the switching circuit is rotated forward and responded in response to the low level signal controlled motor of the second timing means Inverted in the high level signal controlled motor of the second timing means.

By such scheme, control whether control module from power module obtains electric by starting switch, i.e., starting switch is used In output services signal, dedusting module is used to remove the dust on photovoltaic module, and dedusting module includes drive module and cleaning Device, drive module includes walking module and control module, and walking module is moved for cleaning device on photovoltaic module, controls mould Block is used to control walking module to run.The original state of cleaning device is set away from motor, clear to photovoltaic module progress when needing When washing, press starting switch first, output services signal, at this moment the first timing means exported in response to working signal consecutive intervals The high level signal and low level signal of a period of time, and the second timing means exports lasting one section in response to working signal first The low level signal of time, and then output continues the high level signal of phase same amount of time, both when the first timing means is responded The high level signal of one end time can be exported first in working signal, and the second timing means can be defeated first in response to high level signal Go out the low level signal continued for some time, and then output continues the high level signal of phase same amount of time, and switching circuit Rotate forward and inverted in response to high level signal controlled motor in response to low level signal controlled motor, i.e., whenever the first timing means When exporting high level signal, motor is first rotated forward once, then is inverted once, and the first timing means can consecutive intervals output high level Signal, and then can trigger at the reversion that the rotating forward of the multiple circulation continuous of motor for a period of time continues phase same amount of time again, motor When the state of rotating forward, machine shaft starts to rotate coaxially with screw rod, and at this moment screw rod can start to rotate in slide rail, and due to sliding block It is threadedly coupled with screw rod, then sliding block can start to move in slide rail, because cleaning device is arranged on the cunning on two slide rails Contradicted between block and with photovoltaic module, then cleaning device can move with the motion of sliding block and wipe the dirt on photovoltaic module Sand, when motor reversal, screw rod starts to rotate backward, and makes sliding block start to run back with cleaning device, thus completes One wiping process, when the first timing means exports next section of high level signal, motor can start next section of rotating, from And repeatedly circulation is wiped on photovoltaic module with cleaning device, cleaning photovoltaic module that can be cleaner.

Further, the switching circuit includes contact one, contact two, contact three, contact four and relay KA, described Relay KA includes induction coil, the K1 of contact switch one and the K2 of contact switch two, during the relay KA responses high level signal, The K1 of contact switch one is connected with contact two, and the K2 of contact switch two is connected with contact four, controlled motor reversion.

By such scheme, original state is that the K1 of contact switch one is contacted with contact one, the K2 of contact switch two and contact three Contact, when pressing starting switch K, motor starts to rotate forward, the high level exported as relay KA in response to the second timing means During signal, the K1 of contact switch one leaves contact one and contacted with contact two, while the K2 of contact switch two can leave contact three and contact Four contacts, controlled motor starts reversion, and then switching circuit can be made to be controlled in response to the low level signal of the second timing means Motor is rotated forward and inverted in response to the high level signal controlled motor of the second timing means.

Further, first timing means includes the multivibrator that 555 timers are made, and first timing is filled The coupling of pin 3 and the second timing means of 555 timers in putting.

By such scheme, when the first timing means is in response to working signal, because CA has little time charging, the first timing is filled The pin 2 of 555 circuits in putting is in zero level, causes its output pin 3 to be output as high level, when power supply passes through resistance RA, resistance RB to electric capacity CA be charged to Vc >=Vcc when, output pin 3 is changed into low level from high level, and electric capacity CA is through resistance RB With the discharge switch tube discharge of internal circuit, when discharging into Vc≤Vcc, output pin 3 is changed into high electricity by low level again Flat, now electric capacity charges again, and this process can go on again and again, self-oscillation is formed, so that consecutive intervals are defeated Go out the high level signal and low level signal of a period of time.

Further, second timing means includes the monostable flipflop that 555 timers are made, second timing The pin 3 of 555 timers of device is coupled to relay KA.

Pass through such scheme, monostable flipflop only one of which stable state, a temporary stable state, in the effect of applying pulse Under, monostable flipflop can be turned to a temporary stable state from a stable state, due to the effect of RC time delay processes in circuit, The transient state maintains a period of time to be returned to original stable state, and the time that temporary stable state is maintained depends on RC parameter value, using monostable State trigger can only export the low level signal that once continues for some time and the persistently high level signal of same time, and such the Two timing means will export the low level signal continued for some time first in response to the high level signal of the first timing means, And then output continues the high level signal of phase same amount of time.

Further, the one side that the cleaning device is included on cleaning shell, the cleaning shell close to photovoltaic module is detachable It is connected with cleaning part.

By such scheme, what cleaning part was set is detachably connected with cleaning shell, be easy to carry out cleaning part cleaning and Change.
