Detailed description of the invention
As depicted in figs. 1 and 2, remove obstacles automatically in a kind of photovoltaic module surface and shading integrated system includes a base 1, described base 1 is fixed with support 2, described support 2 is provided with photovoltaic battery panel 3.When arranging photovoltaic battery panel 3, in order to make photovoltaic battery panel 3 better absorb sunshine, the general slant setting of photovoltaic battery panel 3, surface of photovoltaic cell panel is preferably perpendicular with incident sunshine.The present invention also comprises the puggaree 5 be arranged on above photovoltaic battery panel, and described puggaree front end is fixed with brush 6 of removing obstacles.Described photovoltaic battery panel both sides are fixed with puggaree draw off gear, and described puggaree is wound on puggaree draw off gear.Can be packed up by puggaree by puggaree draw off gear and decontrol like this, because brush of removing obstacles is fixed on puggaree front end, while folding and unfolding puggaree, brush nature of removing obstacles can clean surface of photovoltaic cell panel.
Further, puggaree draw off gear of the present invention comprises the puggaree spool 4 and silk thread rolling wheel 10 that are separately positioned on photovoltaic battery panel two ends, and described silk thread rolling wheel 10 is fixed on the motor output revolving shaft 8 of drive motors 13.Described motor output revolving shaft 8 and puggaree spool 4 are all provided with belt pulley, be respectively the pusher side belt pulley 11 be arranged on motor output revolving shaft 8 and the axle side belt pulley 15 be arranged on puggaree spool 4, described pusher side belt pulley 11 is connected by belt 12 with axle side belt pulley 15.Described puggaree 5 is wound on puggaree spool 4, described in remove obstacles on brush 6 and be connected with silk thread 7, described silk thread 7 other end is wound on silk thread rolling wheel 10.
Further, brush normal mobile to control to remove obstacles, the side at the upper and lower two ends of described photovoltaic battery panel is provided with puggaree position detecting switch.Detected the position of brush of removing obstacles by puggaree position switch, judge the state of puggaree, to control the rotating work of drive motors, ensure all to remove obstacles or sunshade to whole photovoltaic battery panel.The puggaree position detecting switch that present embodiment adopts is travel switch, comprises the pusher side travel switch 9 be arranged near motor side and the axle side travel switch 16 be arranged near puggaree spool side.Certainly, puggaree position controlling switch of the present invention also can adopt infrared switch or optoelectronic switch, described infrared switch or optoelectronic switch comprise transmitter and receiver respectively, when dedusting snow removing brush is between transmitter and receiver, the reception of infrared ray or light will be cut off, produce signal, thus detect the position of brush of removing obstacles, judge the state of puggaree.
A kind of photovoltaic module of the present invention surface is removed obstacles as follows with the operation principle of shading integrated system automatically: as shown in Figure 2 and Figure 4, need to photovoltaic battery panel 3 carry out dedusting or snow removing etc. remove obstacles operation time, control system starts drive motors 13 and rotates forward, motor output revolving shaft 8 drives curled hair wheel 10, silk thread 7 furls by pusher side belt pulley 11, and brush 6 of removing obstacles will pull to motor side by such silk thread 7; Meanwhile, pusher side belt pulley 11 drives belt 12, axle side belt pulley 15, drives puggaree spool 4, so puggaree 5 launches with same speed by puggaree spool 4.When brush 6 of removing obstacles moves to the position of pusher side travel switch 9, the on off state of pusher side travel switch 9 changes, signal is sent to control system, control system controls motor 13 and reverses, such pusher side belt pulley 11 just drives puggaree spool 4 puggaree 5 and brush 6 of removing obstacles to be furled, when brush 6 of removing obstacles moves to the position of axle side travel switch 16, the on off state of axle side travel switch 16 changes, signal is sent to control system, control system controls drive motors 13 and rotates forward, again pull brush of removing obstacles to swipe toward motor side, launch puggaree 5.So repeatedly back and forth swipe and repeatedly just can carry out the operations such as dedusting, snow removing, deicing to the surface of photovoltaic battery panel 3, be eliminated out the dust on cell panel surface, accumulated snow passes through dirt snow output spot and drop down onto ground.Of the present invention go out dirt snow output spot be between photovoltaic battery panel 3 and silk thread rolling wheel 10, be provided with some troubleshooting through holes 14, described through hole becomes yi word pattern to arrange.The barrier such as dust or accumulated snow is pushed into troubleshooting through hole 14 by each reciprocating motion of brush of removing obstacles, and barrier drops down onto ground from troubleshooting through hole 14.Because photovoltaic battery panel 3 is obliquely installed, so more helps and discharge from troubleshooting through hole 14 with barrier.Certainly, it is troubleshooting groove 17 as shown in Figure 5 that troubleshooting through hole 14 of the present invention also can change into, and such conversion all drops within protection scope of the present invention.
As shown in Figure 3, when photovoltaic system generation abnormal state (as system short-circuit, local pyrexia etc.), control system starts drive motors 13 and is launched by puggaree 5, when brush 6 of removing obstacles moves to the position of pusher side position switch 9, the on off state of pusher side position switch 9 changes, send signal to control system, control system controls motor 13 and embraces, and stops operating.Such puggaree 5 is just fully expanded, and has sheltered from sunshine, realizes disconnecting dc source safely.
When the drive motors 13 in said mechanism, curled hair wheel 10, pusher side belt pulley 11, axle side belt pulley 15, belt 12, remove obstacles any one device failure such as brush 6, puggaree spool 4 and cisco unity malfunction time, circuit for controlling motor by the state situation of change of two travel switches, can be analyzed, identifies fault.When said mechanism is normal, when motor is carried out the instruction of dedusting snow removing action repeatedly, pusher side travel switch 9, the state of axle side travel switch 16 two travel switches can periodically change.When in said mechanism, travel switch is normal, but during whole mechanism's cisco unity malfunction, when motor is carried out the instruction of dedusting snow removing action repeatedly, dedusting snow removing brush can not touch pusher side travel switch 9, one or two in axle side travel switch 16 two travel switches, the state of two travel switches can not periodically change.
When the line out of service of pusher side travel switch 9; brush 6 of removing obstacles can be stuck on pusher side travel switch 9; or cross pusher side travel switch 9; held by puggaree spool 4; drive motors is caused to rotate forward stall, because drive motors band rotation-clogging protection function, so therefore drive motors can not damage; now, control circuit detects that fault is come.
When the line out of service of axle side travel switch 16; brush 6 of removing obstacles can be stuck on axle side travel switch 16; or cross axle side travel switch 16; blocked by the fixed mount below puggaree spool 4; cause drive motors reversion stall, because drive motors band rotation-clogging protection function, so therefore drive motors can not damage; now, control circuit detects that fault is come.
When removing the operation to dedusting snow removing sun-shading mechanism after systems axiol-ogy to fault immediately, control circuit externally can send fault-signal, notifies attendant in time.
Although the foregoing describe the specific embodiment of the present invention, those of skill in the art in the art should be appreciated that these only illustrate, can make various changes or modifications, and do not deviate from principle of the present invention and essence to these embodiments.Scope of the present invention is only defined by the appended claims.
