The embodiment describes a cleaning device for a photovoltaic panel, please refer to fig. 1, which includes a brush switching mechanism, a travel driving mechanism, a dust-collecting filtering mechanism and an energy storage control mechanism.

The energy storage control mechanism mainly comprises a camera 5, a control circuit 5, a storage battery 7, a sub photovoltaic panel 6 and a standby battery pack 8. The high-capacity storage battery 7 is connected with the sub-photovoltaic panel 6, the storage battery 7 supplies power during working, and the sub-photovoltaic panel 6 charges the storage battery 7 during rest. The control circuit 5 is used to control the switching and motion states of other components. And the standby battery pack 8 ensures the stable operation of the equipment.

The walking driving mechanism mainly comprises an upper walking wheel 16, a lower walking driving side wheel 24, a lower walking driving clamping wheel 25 and a walking driving motor 26, when the mechanism needs to move, the control circuit 6 controls the walking driving motor 26 to operate, and drives the upper walking wheel 16, the lower walking driving side wheel 24 and the lower walking driving clamping wheel 25 to control the movement of the cleaning mechanism.

The brush switching mechanism mainly comprises a support frame 3, a straight bevel gear group 10, a brush 11, a driving motor controller 12, a driving motor 13, a coupling 14, a worm 15, a transmission shaft 17, a bearing with a seat 18, a worm gear 19, a rotating brush driving motor 20, a switching turntable 21, a spiral rolling brush 4, a rotating brush 22 and a cleaning rag 23. The driving motor 13 is connected with the worm 15 through a coupling 14, and a transmission shaft 17 is provided with a bearing 18 with a seat up and down.

As an exemplary implementation manner, the lead angle of the worm 15 is smaller than the equivalent friction angle between the meshed worm wheels 19, and the mechanism has a self-locking performance, that is, the worm wheels 19 cannot drive the worm 15 to rotate, so that the change of the switching form caused by the error of the control system is avoided in the cleaning process, and the self-locking of the brush switching turntable is realized.

Referring to fig. 2, spiral round brush 4 among the brush switching mechanism includes the roller and distributes a plurality of bristles that are the heliciform and arrange on the roller, and the precession direction that the heliciform was arranged is followed the extending direction of roller, like this in the clearance process, the axial effort of usable brush hair gathers the dust to the whole lower extreme of mechanism, is convenient for collect. The bristles of the spiral rolling brush 4 are made of polypropylene materials, harder brushes can easily remove dirt with larger surfaces and difficult removal, and the spiral rolling brush is selected for use.

The rotating brush 22 comprises a roller shaft and a plurality of bristles which are distributed on the roller shaft and are circumferentially arranged, and the bristles are circumferentially arranged, so that the photovoltaic panel can be cleaned only by rotation. The rotating brush 22 is used for cleaning the remaining fine dust, and the rotating brush mainly selects a nylon material with better softness, recoverability and wear resistance, has better light transmittance and relative loss rate, and is not easy to scratch the surface of the photovoltaic panel assembly.

The cleaning wiper 23 is mainly used for removing dust and dirt such as bird droppings which are not suitable for removal by a rolling brush.

Referring again to fig. 1 and 3, the photovoltaic panel to be cleaned is placed at the periphery of the cavity surrounded by the spiral rolling brush 4, the rotating brush 22 and the cleaning rag 23, i.e. the photovoltaic panel to be cleaned can normally only contact one of the spiral rolling brush 4, the rotating brush 22 and the cleaning rag 23, but can not contact any two of the spiral rolling brush 4, the rotating brush 22 and the cleaning rag 23.

When observing the stains of different types from the camera 5, the worker adjusts the driving motor controller 12 connected with the control circuit 6 to drive the worm wheel 19 to move while moving the worm 15 by adjusting the driving motor 13, and the worm wheel 19 and the straight-tooth bevel gear set 10 on the same transmission shaft move simultaneously, so that the movement of the switching turntable 21 is adjusted. The switching rotary disc 21 is used for switching different cleaning modes, when determining which cleaning mode is selected for the position, the switching rotary disc 2 rotates to enable only one of the spiral rolling brush 4, the rotating brush 22 and the cleaning rag 23 to contact the surface of the photovoltaic panel to be cleaned, at the moment, the switching rotary disc 21 is operated to rotate, and the operation driving motor 13 stops working. When the spiral rolling brush 4 is selected as the cleaning mode, the spiral rolling brush 4 is tightly attached to the surface of the photovoltaic panel, and the switching turntable 2 is operated to rotate in a small amplitude until the spiral rolling brush 4 rotates along with the switching turntable 2 in the small amplitude rotation process; or the traveling driving mechanism drives the support frame 3 to move until the spiral rolling brush 4 axially moves, so that the spiral rolling brush 4 automatically rotates, and finally the spiral rolling brush 4 can clean the photovoltaic panel.

When the cleaning mode is switched to the brush 22, the brush motor 20 is used to drive the brush 22 to rotate. When cleaning mode switches to cleaning rag 23, it compresses tightly to adhere to photovoltaic board surface, along with the removal rotation of whole mechanism. The three switches and observes the difference of the degree of dirt through the staff and carries out manual regulation, and the signal transmission is for cleaning mechanism driving motor through worm wheel 19, worm 15 and bevel gear group 10 adjustment switching carousel. When cleaning the mode and adjusting for changeing brush 22, brush 11's line is arranged in the axle that straight bevel gear group 10 is connected, the inside of axle sets to hollow, brush 11 links to each other with changeing brush driving motor 20 through switching carousel 21 from the interior lead-through of hollow shaft, it rotates to change brush driving motor 20 drive commentaries on classics brush 22, thereby play the effect of cleaning, this sets up the job stabilization nature who has improved brush group, when surperficial dirt is great and difficult getting rid of, switch into the harder spiral round brush of material, gather the lower extreme of whole cleaning mechanism with the dust when getting rid of the dust, it collects to wait to inhale dust filtering mechanism, when tiny and handling easily of surperficial dust, choose the softer commentaries on classics brush 22 of material for use to clear away, when the place has difficult round brush to clear away with such as bird excrement, switch to cleaning rag 23 and clear away.

The dust collection and filtration mechanism mainly comprises a servo motor 27, a dust collection fan 2 and a dust filtration bag 1, wherein the servo motor 27 mainly controls the operation of the dust collection fan 2, and can adjust the wind power of the dust collection fan 2, increase the wind power when more dust exists, and reduce the wind power to reduce loss when less dust exists. Through the operation of the dust suction fan 2, dust is collected in the dust filter bag 1, and the dust filter bag is made of wave-shaped meshes and paper materials so as to be conveniently replaced at any time.

When the cleaning mechanism moves on the solar photovoltaic panel through the driving wheel, the spiral rolling brush 4, the rotating brush 22 and the cleaning rag 23 are matched with each other to realize the cleaning operation of the solar photovoltaic panel, and meanwhile, the dust is cleaned to move towards the lower end of the mechanism and is sucked into the dust filtering bag 1 through the dust absorption fan 2 to realize the dust-free operation.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application.
