[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4A photovoltaic panel bracket with an electrically controlled self-cleaning system is shown, comprising a bottom support frame 1 and an aluminum frame 2 for assembling photovoltaic panels, a back rail 3 is bolted to both sides of the back of the aluminum frame 2, an N-shaped translation adjustment frame 4 is movably assembled on the outer side of the aluminum frame 2 through the back guide rail 3, an arc-shaped protective cover 5 is welded and fixed on the inner side of the translation adjustment frame 4, an electrically controlled cleaning brush 6 is installed on the inner side of the arc-shaped protective cover 5, a detachable bottom liquid storage tank 7 is installed inside the bottom support frame 1, a bottom cleaning bin 8 is fixedly installed on the bottom side wall of the aluminum frame 2 through the bottom side frame, 13 atomizing nozzles 9 connected to the inside of the detachable bottom liquid storage tank 7 are provided on the low outer side surface of the arc-shaped protective cover 5, and 13 high-pressure spray heads 10 connected to the inside of the detachable bottom liquid storage tank 7 are provided on the high outer side surface of the arc-shaped protective cover 5.

[0030] Working principle: In the idle state, the translation adjustment frame 4 and the arc-shaped protective cover 5 are located above the back track 3, which does not affect the surface illumination range of the photovoltaic panel. When the power generation of the photovoltaic panel is significantly reduced under the same lighting conditions, it means that cleaning is needed, and then the translation adjustment frame 4 moves down along the back guide rail 3, and at the same time, the detachable bottom liquid storage tank 7 supplies liquid to the atomizing nozzle 9, and then while the arc-shaped protective cover 5 moves down, the electrically controlled cleaning brush 6 performs synchronous rolling cleaning, and then the high-pressure spray head 10 is flushed to flush the impurities generated by cleaning downwards, thereby improving the cleaning effect, and finally the arc-shaped protective cover 5 moves down to the bottom cleaning bin 8 for self-cleaning, and then it is lifted and reset to the top, and the residual liquid on the surface of the photovoltaic panel is scraped off during translation.

[0031] In order to facilitate compartmentalized storage, the interior of the detachable bottom liquid storage tank 7 is divided into a cleaning liquid storage chamber 71 and a sewage storage chamber 72 by a partition.

[0032] In order to cooperate with the liquid supply, a centrifugal liquid pump 11 is installed on the inner bottom surface of the cleaning liquid storage chamber 71, and the upper surface of the detachable bottom liquid storage tank 7 is fixedly equipped with an upper electric control regulating valve 12 connected to the liquid outlet of the centrifugal liquid pump 11. The upper electric control regulating valve 12 is fixedly connected to the atomizing nozzle 9 and the high-pressure spray head 10 through an external discharge pipe 13.

[0033] The upper electrically controlled regulating valve 12 can change the connection state between the centrifugal liquid pump 11 and the atomizing nozzle 9 or the high-pressure spraying nozzle 10, so that the centrifugal liquid pump 11 can be controlled to supply liquid to the atomizing nozzle 9 or the high-pressure spraying nozzle 10 separately, or simultaneously.

[0034] In order to facilitate the return of sewage into the sewage storage chamber 72 , a bottom sewage outlet is provided on the lower surface of the bottom cleaning bin 8 , and a bottom sewage hopper 14 connected to the sewage storage chamber 72 is fixedly mounted at the lower end of the bottom sewage outlet.

[0035] In order to cooperate with assembly and driving, the translation adjustment frame 4 includes an N-shaped structure external frame 41, a transverse assembly seat 42 fixedly installed on the inner walls on both sides of the external frame 41, and a first electrically controlled driving wheel 43 and a second electrically controlled driving wheel 44 installed on the inner side of the transverse assembly seat 42.

[0036] In order to cooperate with guidance and transition, the back track 3 includes an inclined straight guide rail 31 fixed to both sides of the back of the aluminum frame 2 through an inner mounting frame, an arc-shaped transition guide rail 32 fixedly connected to the upper end of the inclined straight guide rail 31, and a top straight guide rail 33 fixedly connected to the upper end of the arc-shaped transition guide rail 32.

[0037] The translation adjustment frame 4 moves along the back track 3 through the first electrically-controlled driving wheel 43 and the second electrically-controlled driving wheel 44 on both sides. When the translation adjustment frame 4 moves to the top straight guide rail 33, the translation adjustment frame 4 and the arc-shaped protective cover 5 are arranged vertically. When the translation adjustment frame 4 descends along the inclined straight guide rail 31, the arc-shaped protective cover 5 and the electrically-controlled cleaning brush 6 inside it can be driven to roll and clean the surface of the photovoltaic panel. When the translation adjustment frame 4 descends to the bottom along the inclined straight guide rail 31, the arc-shaped protective cover 5 will be closed with the bottom cleaning chamber 8 to form a closed chamber.

[0038] In order to cooperate with the internal drive adjustment, inner side adjustment tooth grooves 34 cooperating with the first electrically controlled drive wheel 43 and the second electrically controlled drive wheel 44 are provided on the inner side surfaces of the inclined straight guide rail 31 , the arc-shaped transition guide rail 32 and the top straight guide rail 33 .

[0039] The transverse assembly seat 42 is inserted into the back rail 3 through the first electrically-controlled drive wheel 43 and the second electrically-controlled drive wheel 44 and movably assembled with the back rail 3, and then the first electrically-controlled drive wheel 43 and the second electrically-controlled drive wheel 44 are engaged with the tooth surface inside the inner adjustment tooth groove 34, and the first electrically-controlled drive wheel 43 and the second electrically-controlled drive wheel 44 move along the inner adjustment tooth groove 34 by rotating.

[0040] In order to guide the cleaning liquid of the atomizing nozzle 9 and the high-pressure spraying nozzle 10 into the interior, a lateral air guide cover 15 cooperating with the atomizing nozzle 9 and the high-pressure spraying nozzle 10 is fixed on the outer surface of the bottom cleaning chamber 8 .

[0041] The lateral air guide cover 15 is connected with the interior of the bottom cleaning chamber 8. When the translation adjustment frame 4 moves to the lowest position along with the back track 3, the arc-shaped protective cover 5 and the bottom cleaning chamber 8 are closed. Then the openings of the atomizing nozzle 9 and the high-pressure spray head 10 are inserted into the upper opening of the lateral air guide cover 15 to form a series flow channel with the interior of the bottom cleaning chamber 8. At this time, when the atomizing nozzle 9 and the high-pressure spray head 10 spray the cleaning liquid, the cleaning liquid will be introduced into the bottom cleaning chamber 8.

[0042] In order to improve the self-cleaning effect, a bottom scraping frame 16 for improving the self-cleaning effect of the electrically controlled cleaning brush 6 is elastically mounted on the inner bottom surface of the bottom cleaning chamber 8 .

[0043] When the bottom cleaning chamber 8 and the arc-shaped protective cover 5 are closed, the self-cleaning mode is turned on. At this time, the electrically-controlled cleaning brush 6 rotates at a high speed, and the centrifugal force generated will contact the bottom scraping frame 16, thereby improving the separation effect of impurities on the electrically-controlled cleaning brush 6.

[0044] In order to improve the cleaning effect, an upper surface of the upper electrically controlled regulating valve 12 is fixedly equipped with an upper storage cylinder 17 for storing the cleaning stock solution.

[0045] The lower end of the top storage cylinder 17 is fixedly connected to the external drainage pipe 13 of the atomizing nozzle 9 through an electrically controlled opening and closing valve. When the surface cleanliness of the photovoltaic panel is not high, by opening the electrically controlled opening and closing valve of the prior art, the cleaning stock solution inside the top storage cylinder 17 will be drawn into the external drainage pipe 13 due to gravity and the adsorption force inside the external drainage pipe 13, and finally sprayed from the atomizing nozzle 9 to the surface of the photovoltaic panel, which can improve the cleaning effect, and then the electrically controlled cleaning brush 6 is used for rolling cleaning, and then the high-pressure spray head 10 is used for flushing after cleaning.

[0046] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
