Description

Photovoltaic plant sweeping robot based on the direct dedusting of blower fan and method of work thereof
Technical field
The present invention relates to a kind of be applicable to the intelligent robot that photovoltaic plant solar panels clean, in particular, relate to a kind of with Dust, as main dust discharge assembly, in walking and cleaning process, is sucked by blower fan, discharges by centrifugal blower repeatedly, until Blow off the photovoltaic plant sweeping robot on ground and method of work thereof.
Background technology
The area that climatic environment is more severe is generally built in large-sized photovoltaic power station in, and the general dust storm in these areas is serious, drought and water shortage. Dust and dust storm, can block the photovoltaic panel assembly assimilation effect to solar energy, be substantially reduced photovoltaic panel to solar energy for a long time Absorption efficiency.Moreover, dust, dust storm and other fouling products, long shade can be formed on photovoltaic panel surface, enter And produce hot spot effect, if not in time photovoltaic module is cleaned, it will the generated energy of photovoltaic plant is greatly reduced, to electricity The economic benefit stood and the life-span of photovoltaic module, have a negative impact.
In current multiple photovoltaic module automatization cleaning equipment, various unidirectional or transverse and longitudinal twin fixed guide-vane formula cleaning equipment, owing to being subject to To the arrangement mode of photovoltaic panel, the longitudinal length of group string, the unit weight of equipment, drive energy, the multiple condition such as self maintained Restriction, its drawback the most gradually appears.Monomer stand alone type is creeped sweeping robot, it has also become photovoltaic module cleans field and grinds at present The dominant direction sent out.
The sweeping efficiency of sweeping robot and the dependence to attendant, be that two of this field consider core.And some is creeped clearly Sweep robot (such as two-legged type), in most walking with in turnaround time, only achieve the movement of station, unrealized cleaning merit Can, inefficient;Also have the capacity of some sweeping robots of creeping (such as Japan SINFONIA) dust-collecting box, limit it effective Working time, and create the very big dependence to attendant.
Summary of the invention
For current photovoltaic plant automatic cleaning equipment sweeping efficiency and to attendant's dependency in terms of exist deficiency, this A kind of photovoltaic plant sweeping robot based on the direct dedusting of blower fan of bright offer, and its method of work has been done the planning of science.

Detailed description of the invention
The structure of the present embodiment robot is as it is shown in figure 1, power-supply system 1 includes solar panel, controller and and controller The ultracapacitor assembly etc. connected.Running gear 2 includes crawler travel assembly, movable motor etc., by the fuselage left and right sides Each motor, the Athey wheel on each self-driven both sides, make monolateral crawler belt advance on solar panels surface, retreat, static, speedup, Slow down, it is achieved the walking of robot and turning function.Dust pelletizing system 3 includes centrifugal blower, motor, output airduct etc..Clearly Sweep system 4 and include disc brush assembly, driving gear component and driving motor etc., drive motor to drive disc brush assembly, make disc brush too Sun can plate surface at the uniform velocity or speed-changing rotation.Control system 5 includes MCU mainboard, various sensor interface and integrated circuit thereof etc..
In power-supply system 1, the solar panel of robot upper surface obtains solar energy, quick by ultracapacitor assembly Discharge and recharge, it is achieved the electricity needs of other each system of sweeping robot.
Arrange in the robot fuselage left and right sides patrols limit sensor, and the left side of control robot body or right side are all the time along the sun The metal upper edge of energy plate or lower edge straight line moving, and the displacement transducer that robot front and back end is arranged, control robot body When crossing over one piece of solar panels every time, adjust a pose, it is ensured that its walking path is always straight line;It is arranged on blower fan suction inlet Dust sensor be responsible for detecting the concentration kicked up of dust, when concentration is within certain threshold range, cleans motor and at the uniform velocity turn Dynamic, drive disc brush at the uniform velocity to clean, movable motor also drives crawler belt at the uniform velocity to walk;When detecting that dust concentration exceeds certain threshold value model Outside enclosing, cleaning motor and start speedup or deceleration, if dust concentration is relatively low, crawler belt accelerates walking, and disc brush is rotated in deceleration, otherwise, If dust concentration is higher, crawler belt slows down and walks, and disc brush is accelerated to rotate, to improve work efficiency and to realize the different cleaning degree sun The cleaning of energy plate.In addition, the fall arrest infrared sensor of robot body end, ultrasonic ranging avoidance sensor and The blower fan of inside, disc brush, Athey wheel etc. drive the current sensor of motor, and respective signal is passed to MCU mainboard, then by control The analysis of system processed, comparison and fusion, send a command to each motor and moving component, then by the speed governing of motor, rotating, Shut down, it is achieved the closed loop control of robot.
In dust pelletizing system 3, by the high speed rotating of centrifugal fan blade, by the dust of suction along output airduct, excrete. Output airduct can be arranged on the both sides of robot fuselage, it is also possible to is positioned only on a side.If fuselage both sides have defeated Discharge pipe, at machine man-hour, when arriving solar array edge, can turn around to exchange the most end to end and turn To, however it is necessary that one of them airduct of closedown, to ensure that dust the most all blows to solar panels low-lying.Although having Part dust, still falls back to photovoltaic solar panel surface, and robot, can be by this part dust weight when next line walking work New suction, discharge, until last column, ground that dust is blown off.Further, even if there being the dust being scattered to continue to be retained in Solar panels surface, one is floating ash, and outdoor mild wind can be blown away, and two is solar panels surface uniform dust on a small quantity, to it Absorb the efficiency of solar energy, constitute impact hardly.So, centrifugal blower dust suction timely and dust discharge, to solar panels surface The raising of sweeping efficiency, has and promotes effect greatly.
As in figure 2 it is shown, the present embodiment is only provided with output airduct in fuselage side, and it is low towards solar panels all the time to export airduct One side of physical features.The present embodiment sweeping robot operating path is planned to: first it is after A station, along solar energy The horizontal straight line moving of plate also works, as shown in station B;When close to solar array edge, 90 degree of one spacing of turning right From, stopping, minor radius 90 degree retrogressing, it is not necessary to turn around, direct afterbody becomes head, and head becomes afterbody, as shown in station C; Straight line moving working, as shown in station D the most again;When close to another edge of solar array, left-hand rotation 90 Degree certain distance, stops, minor radius 90 degree retrogressing, and tail becomes head again, and head becomes tail, as shown in station E;The most straight Line is walked and is worked, as shown in station F.Path planning according to this, iterative cycles, until cleaning solar energy in large area plate array Complete.
