Photovoltaic generation, its basic principle is exactly " photovoltaic effect ".Photon irradiation is on metal time, and its energy can all be absorbed by certain electronics in metal, and the energy of Electron absorption is enough large, can overcome the acting of metal inside gravitation, leaves metal surface and escapes out, becomes photoelectron.The solar radiation quantity that photovoltaic cell component is subject to is larger, and system energy output is higher., there are a large amount of dusts, foreign material in cell panel any surface finish, is very easy to be attached to cell panel surface in atmospheric environment, after impurity gathers for a long time, can greatly reduce cell panel generating efficiency.US National Aeronautics and Space Administration studies show that: every square metre only has the staubosphere of 4.05 grams just can reduce solar energy conversion 40%, and especially poor at vegetation cover, day higher northern area of irradiation intensity condition, affects more obvious.If manually clean, difficulty is larger, and cost is higher.The paper of domestic Liang Jia research institution shows, the test of 2MW power station, Bengbu, the dust accumulation of 20 days affects energy output and declines 24%, and with respect to 15 days, not clean assembly generating efficiency improved average 25% to the clean clean assembly of Shenzhen BIPV project testing.
Therefore, for above-mentioned situation, there is solar cell board cleaning device, by automatic control, the dust on solar panel has been removed automatically, improved the operating efficiency of cell panel, reduced the electric energy loss that solar panel causes because of dust covering.At present such automatic cleaning apparatus complex structure, transmission mechanism parts are many and manufacturing cost is higher, be difficult for large area and use.
Application number is in 201020101440.3 utility model patent, disclosed a kind of automatic dust-collecting equipment of solar cell panel: solar panel is contained in fixed support, fixed support adopts rectangle or square frame, dust-scraping device two ends are contained on symmetrical linear motor, and linear motor is placed on the parallel track above fixed support both sides.When dust cleaning apparatus is started working, driver module drives two linear motors to move simultaneously, drives dust-scraping device action, and dust-scraping device adopts flexible rubber dust blowing sheet.Position transducer is equipped with at fixed support two ends, and when dust-scraping device arrives cell panel one end, position transducer signal transmission, moves dust-scraping device in the other direction.Dust-scraping device, under the drive of drive unit, completes the clean of cell panel surface by back and forth movement.
There is following shortcoming in this utility model:
Fixed support adopts frame structure, and cell panel is contained in fixed support, if install this dust cleaning apparatus additional for mounted cell panel, the cell panel of monolithic or negligible amounts is more applicable, and large area, a fairly large number of cell panel are installed difficulty.Dust-scraping device material is flexible rubber, and in the poor area of environmental condition, rubber easily occurs aging, greatly affects the clean of cell panel.
It is clean that this utility model can only adapt to small size monoblock battery plate simultaneously, can not realize area battery plate clean.In addition, because this utility model adopts the reciprocal dust blowing action of rubber strip, when cell panel surface dirt exists gravel, can damage photovoltaic cell component watch crystal, affect cell panel useful life.
In the utility model patent of application number 201220009745.0, disclosed a kind of automatic dust-collecting equipment of solar cell panel: this cleaning dust remover comprises and moves up and down device, apparatus capable of fluctuating, storage tank, move up and down device and comprise angle adjustable cleaning head, cleaning head support, motor and line slideway, cleaning head support one end is connected with angle adjustable cleaning head, the other end is connected with line slideway, apparatus capable of fluctuating and move up and down device and be communicated with, apparatus capable of fluctuating is connected with storage tank, storage tank inside is equipped with high direct voltage water pump, described apparatus capable of fluctuating comprises flexible water pipe, flexible water pipe upper end is communicated with angle adjustable cleaning head, flexible water pipe lower end is connected with high direct voltage water pump.When dedusting starts, apparatus capable of fluctuating rises to specified altitude assignment by angle adjustable cleaning head, angle adjustable cleaning head and cell panel laminating, and high-pressure hydraulic pump starts action, water-jet in storage tank is gone out, and angle adjustable cleaning head is clean by having moved up and down along cell panel simultaneously.
This utility model, mainly for solar street light, metope battery panel components, can only adapt to small size monoblock battery plate clean, and for extensive parallel networking type photovoltaic power station, operating efficiency is low, and is not suitable for using on a large scale.Meanwhile, apparatus capable of fluctuating and move up and down device windy and dusty area easily enters gravel in northwest, causes clamping stagnation, has reduced equipment dependability.
As can be seen here, above-mentioned existing solar photovoltaic battery component cleaning device, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.How to found a kind of simple in structure, can large area use and to the undamaged cleaning device of surfaces of cell, becoming the current industry utmost point needs improved target.
