Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
Be illustrated in figure 1 the structural principle block diagram that the utility model is applicable to the automatic snow-removing device embodiment of extremely frigid zones roof photovoltaic power station, as seen from the figure, this device comprises the heating film for being attached on photovoltaic module, photovoltaic module is also provided with the cleaning assembly for cleaning surperficial accumulated snow, cleaning assembly comprises along photovoltaic module bearing of trend or the Snow cleaning brush that arranges perpendicular to its bearing of trend, Snow cleaning brush is connected with driving the motor cleaning assembly movement by transmission mechanism, this Snow cleaning brush is hairbrush, has towards the working face of photovoltaic module.
The heating film of the present embodiment is attached on the backboard of photovoltaic module, and heating film and motor are by photovoltaic module or storage battery power supply.
As shown in Figure 2, the transmission mechanism of the present embodiment comprises perpendicular to Snow cleaning brush 2 bearing of trend and is arranged at two guide rails 3 of photovoltaic module 1 edge, the two ends place of guide rail is provided with guide rail draw-in groove, every bar guide rail all arranges a driving chain 4 by corresponding guide rail draw-in groove, and the two ends of Snow cleaning brush are separately fixed on two driving chains; As shown in Figure 3, driving chain comprises and is assemblied in drive sprocket 41 in two guide rail draw-in grooves respectively and by movable sprocket 42, one of them drive sprocket is connected with motor, connected by transmission shaft driven between two drive sprockets 41, power transmission shaft is driven by gear driven mechanism by motor, and motor is herein two-dimentional asynchronous machine, increases the scope of snow brush cleaning, meet different needs according to actual needs, control model is various.
This device also comprises and being arranged on photovoltaic module correspondence position for detecting the light sensor of intensity of illumination and the pressure sensor for detecting surface area crushing by snow power, the present embodiment arranges multiple pressure sensor and light sensor under the backboard of assembly, both it can have been avoided by snow and ice cover, simultaneously multiple transducer coordinates with controller and judges whether by snow and ice cover accurately, the accuracy of enhancing judgement.
Pressure sensor and light sensor are arranged on respectively the diverse location of roof photovoltaic module, each pressure sensor and light sensor detect the corresponding local accumulated snow pressure of roof photovoltaic module and light conditions respectively, and are converted into the signal of telecommunication and are sent to main control unit.Main control unit is calculated product crushing by snow power and intensity of illumination respectively, and when result is greater than set point, main control unit carries out the execution of command adapted thereto by being sent to heating film controller and electric machine controller after telecommunications.
Operation principle of the present utility model: when the inclination angle of photovoltaic module and horizontal plane is arbitrary value, this automatic snow-removing device is distributed on the photovoltaic module of regional, by control system, corresponding assembly is controlled, this control system comprises main control unit, heating film controller, electric machine controller and charging-discharging controller, this charging-discharging controller is for controlling the charging of photovoltaic module to storage battery and the electric discharge of storage battery, and concrete snow removing process is as follows:
(1) snow, illumination more weak (night, overcast and rainy) time: photovoltaic module is avenged covering and can not effectively be generated electricity, multiple pressure sensor spreads out of the snow-covered signal of telecommunication, light sensor spreads out of the signal of illumination intensity, the signal of main control unit to pressure sensor and light sensor judges, judged result is that photovoltaic module cannot carry out normal power generation, therefore, this main control unit sends the instruction starting automatic snow just to heating film controller and electric machine controller.
(2) photovoltaic module have snow cover but intensity of illumination is higher time: multiple pressure sensor spreads out of the snow-covered signal of telecommunication, light sensor spreads out of the signal of illumination intensity, the signal of main control unit to pressure sensor and light sensor judges, judged result is that photovoltaic module is had ready conditions and generated electricity, but owing to being covered by snow thus cannot normal power generation time, main control unit sends the instruction starting automatic snow to heating film controller and electric machine controller.
Now, first main control unit judges whether photovoltaic module can power for heating film, if passable, by charging-discharging controller closing relay K switch 1, be that heating film is powered, if can not by photovoltaic module, then closing relay K switch 2, starting storage battery is that heating film is powered and made it generate heat.In addition, when photovoltaic module can generate electricity, be simultaneously also for storage battery charges while heating film is powered at photovoltaic module.
After heating a period of time (general 5 minutes), ice and snow nearly melts, remaining accumulated snow on motor controller controls electric motor starting Snow cleaning brush cleaning photovoltaic module, be still now feeding electric motors by main control unit selective light photovoltaic assembly or storage battery, on the basis of snow melt, utilize Snow cleaning brush to clean accumulated snow, thus realize clearing up the accumulated snow of whole photovoltaic arrays.
After accumulated snow cleans out, pressure sensor and light sensor transmit the signal without snow cover to main control unit, main control unit sends the signal stopping accumulated snow cleaning, is disconnected relay K 1 and the K2 of photovoltaic module and storage battery, reduce unnecessary power consumption by charging-discharging controller.
Automatic snow-removing device employing pressure sensor of the present utility model and light sensor detection external environment condition are sent to main control unit and carry out judging whether to send making instruction of sweeping away snow by oneself, adopt multiple pressure sensor scattered distribution, and by the calculating of main control unit, strong interference immunity, and it is high to use reliability; Adopt light sensor transmission light according to strength signal, after intensity of illumination is greater than standard intensity of illumination and the snow cover signal that pressure sensor transmits is greater than set point time just startup automatic snow instruction.First-selected photovoltaic module is as power supply, the cleaning carrying out accumulated snow when illumination meets certain requirement can make full use of photovoltaic module generating, utilize when photovoltaic module cannot generate electricity the electricity of storage battery to start snow-removing device, reduce the capacity of configuration storage battery, improve the useful life of storage battery.
Above embodiment only understands core concept of the present utility model for helping; the utility model can not be limited with this; for those skilled in the art; every according to thought of the present utility model; the utility model is modified or equivalent replacement; any change done in specific embodiments and applications, all should be included within protection range of the present utility model.
