Embodiment one; Referring to shown in Figure 1, the solar panel automatic cleaning device of present embodiment mainly moves back and forth the linkage of realizing cleaning function etc. and partly forms by pedestal box 7, cleaning brush 4, control panel 8, motor 10 and driving under the driving action of motor 10 on the daylighting panel 16 of cleaning brush 4 at solar panel 1.Wherein, pedestal box 7 is used for this clearing apparatus is fixed on solar panel 1, specifically can adopt clamping screw 5 to realize installing and fixing of itself and solar panel 1 framework.
Brush holder 2, fork 11 can be set in said linkage and be hinged on brush holder 2 and fork 11 between connecting rod 3; One end of said fork 11 is fixedly connected with the rotating shaft of motor 10; The other end and connecting rod 3 are hinged, and specifically can be connected with an end hinge of connecting rod 3 through pin; The other end of connecting rod 3 is hinged through pin 15 and brush holder 2, as shown in Figure 2, preferably be hinged on the middle part (the middle part here is meant all the other positions of removing brush holder 2 two ends, need specifically confirm according to the length of fork 11 and connecting rod 3) of brush holder 2.One end and the brush holder 9 of brush holder 2 are rotationally connected, and brush holder 9 is fixedly mounted on the pedestal box 7.Cleaning brush 4 is installed on brush holder 2, when brush holder 2 moves, just can be driven cleaning brush 4 and on the daylighting panel 16 of solar panel 1, move, accomplish the cleaning works of attachments such as dust, sleet.
As a kind of preferred design of present embodiment, said cleaning brush 4 is preferably mounted at brush holder 2 on the side of the daylighting panel 16 of solar panel 1, i.e. brush holder 2 bottom surfaces of direction shown in Figure 1.Pedestal box 7 is fixedly mounted on the end of solar panel 1 one sides; For example grow the end on limit; Then brush holder 2 should extend along an adjacent side direction of solar panel 1 at initial position; For example extend to the broadside of solar panel 1, and the length of brush holder 2 with and the length that goes up the cleaning brush of installing 4 preferably the width edge length with the daylighting panel 16 of solar panel 1 is suitable, promptly equate perhaps to be slightly less than the width edge length of daylighting panel 16.Thus one, driving cleaning brushes 4 at brush holder 2 be fulcrum when rotating with brush holder 9, can obtain the cleaning range of maximum, and then help to improve the photoelectric transformation efficiency of solar panel 1.
For under special weather situation such as sleet, clearing apparatus can be automatically, in time solar panel 1 is carried out cleaning works, and present embodiment also is provided with humidity sensor 6 in said clearing apparatus, be installed on the pedestal box 7, is used for testing environment humidity.The Humidity Detection signal that collects through said humidity sensor 6 sends control panel 8 to via holding wire, carries out cleaning process to determine when starter motor 10.
Said control panel 8 is as the control core of whole system, and is with humidity sensor 6 and 10 corresponding connections of motor, as shown in Figure 3 respectively.When control panel 8 detects the pairing ambient humidity value of Humidity Detection signal through humidity sensor 6 feedback and surpasses the setting value that writes in advance; Think that then the humidity of external environment is excessive; Sleety weather possibly appear; And then 10 runnings of output control signal starter motor, drive link mechanism drives cleaning brush 4 and carries out cleaning works, and rainwater or accumulated snow on the daylighting panel 16 that accumulates in solar panel 1 are in time cleared up.
Under other weather environments; For the dust on the daylighting panel 16 that accumulates in solar panel 1 is regularly cleaned; Preferably at said 7 last set-up time of pedestal box adjusting knob 12; Connect described control panel 8,, change the setting value of regularly cleaning the time through operating time adjusting knob 12 with the environmental aspect of the personnel of maintaining easily according to different regions.
A kind of preferred circuit design as present embodiment; Can said time adjusting knob 12 be connected with the knob of a potentiometer; The power supply terminal of potentiometer is connected dc source, change the resistance of potentiometer, and detect the change in resistance of potentiometer through control panel through the rotational time adjusting knob; And then convert to generate and regularly to clean the setting value of time and preserve, carry out regular cleaning works so that control 4 pairs of solar panels of cleaning brush 1 automatically according to this setting value in the future.
Certainly; Also can directly the setting value of time be cleaned in said timing is solidificated in the software program of system; Control panel 8 can directly call cycle and the frequency that this setting value is confirmed cleaning in running; And then control cleaning brush 4 and carry out regular cleaning works, present embodiment does not specifically limit this.
For each can directly be provided by the battery that is connected with solar panel 1 14 conversions, like Fig. 1, shown in Figure 3 with the required working power of electric loading in the said clearing apparatus.In the present embodiment, the said motor 10 preferred DC speed-reducing that adopt are to make things convenient for the design of power supply circuits.At solar panel 1 duration of work, the electric energy that generates through solar panel 1 conversion exports battery 14 to, is battery 14 charging accumulation of energys.Dc source via battery 14 outputs can generate control panel 8, humidity sensor 6, DC speed-reducing 10 and the needed working power of potentiometer through the voltage conversion circuit voltage stabilizing, is these electricity consumption electric through power line 13.
The preferred microprocessor that adopts cooperates peripheral circuit to set up governor circuit on said control panel 8; Utilize the different I mouth of microprocessor to connect described humidity sensor 6, DC speed-reducing 10 and potentiometer, realize the collection of detection signal and the drive controlling of motor 10.
In order to improve the reliability of system works, preferably said control panel 8, motor 10 and potentiometer are built in the pedestal box 7, the upper shell that the rotating shaft of motor 10 passes pedestal box 7 is connected with fork 11.Humidity sensor 6 can be directly installed on the housing of pedestal box 7, also can only its induction contact be exposed pedestal box housing, and is as shown in Figure 1, with the humidity variation of perception external environment exactly.
The course of work in the face of the solar panel automatic cleaning device that present embodiment proposed specifically describes down.
Usually, solar panel 1 absorbs sunshine, converts electric energy to battery 14 charging accumulation of energys, and then utilizes battery 14 for control panel 8 working power to be provided.The attendant can set the regular cleaning time and the frequency of cleaning brushes 4 through time adjusting knob 12, and it is adjustable that for example cleaning period is set to 1 day, 2 days and 3 days, and each 5 seconds actuation times, 10 seconds, 15 seconds and 30 seconds are adjustable.Control panel 8 regularly drives DC speed-reducing 10 runnings according to time and the frequency set, and then drive link mechanism drives cleaning brush 4 the dust dirt on the cleaning solar panels 1 or rainwater, accumulated snow automatically.During cleaning, DC speed-reducing 10 rotates a circle, and driving pendulum rod 11 rotates a circle, and then to drive brush holder 2 be fulcrum with brush holder 9, is rotated counterclockwise 90 degree earlier, and dextrorotation turn 90 degrees again, accomplishes one and back and forth cleans course of action.In addition,, judge when running into sleety weather, then drive the daylighting panel 16 that DC speed-reducing 10 is cleaned solar panel 1 immediately, to reach the best cleaning effect solar panel 1 when the humidity data that control panel 8 collects according to humidity sensor 6.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
