It needs to be explained that self -charging subassembly 200 is not limited to charging for the battery, also can power supply for other electric equipment, regarding the specific use scene of self -charging subassembly 200, this embodiment does not make limited. Self -charging subassembly cleaning unit 300 is used for cleaning self -charging subassembly 200 installed to photovoltaic cleaning robot body 100.

[0057] Specifically, as shown in the drawings, Figures 3-5 Self -charging subassembly cleaning unit 300 includes moving piece 301, cleaning piece 303 and walking drive arrangement. Among them, moving piece 301 is used for along the extension direction of self -charging subassembly 200, relative to self -charging subassembly 200 movable setting, so that moving piece 301 reciprocating moves, can gradually cover the different areas of self -charging subassembly 200.

[0058] Cleaning piece 303 sets up on moving piece 301, and is used for cleaning self -charging subassembly 200. Cleaning piece 303 can be brush type or silica gel type component etc. only if can through the relative friction of self -charging subassembly 200, wipe off the dust etc. impurity on the surface of self -charging subassembly 200 can. It needs to be explained that cleaning piece 303 in stationary state, cannot cover the whole area of self -charging subassembly 200, and it needs to gradually clean each area of self -charging subassembly 200 by moving.

Through moving piece 301 provides the installation basis for cleaning piece 303, can make cleaning piece 303 have greater coverage span. In order to facilitate understanding, the following are with self -charging subassembly cleaning unit 300 having moving piece 301 as example to introduce.

[0060] With the extension direction of the self-charging assembly 200 as a first direction, and a direction perpendicular to the first direction as a second direction, the moving member 301 can drive the cleaning member 303 to reciprocate along the first direction (for example, move along the length direction of the self-charging assembly 200), and the cleaning member 303 extends along the second direction to cover the area of the self-charging assembly 200 in the second direction (for example, cover the width area of the self-charging assembly 200). Through the movement of the cleaning member 303, the entire area of the self-charging assembly 200 can be covered. Those skilled in the art can understand that, due to different interference conditions in actual scenes, the self-charging assembly 200 may not be able to be completely cleaned due to avoidance of interference components, that is, in the embodiment, the cleaning member 303 is not limited to being able to cover the entire area of the self-charging assembly 200 through movement.

[0061] The walking driving device is used to drive the moving member 301 to reciprocate along the photovoltaic cleaning robot body 100 (or directly drive the cleaning member 303 to reciprocate). In the embodiment, the walking driving device can be arranged on the photovoltaic cleaning robot body 100 or the self-charging assembly 200, and the arrangement position of the walking driving device is not limited in the embodiment, as long as the moving member 301 can be driven to reciprocate along the photovoltaic cleaning robot body 100. The walking driving device can be a push-pull type driving device, that is, the moving member 301 is driven to move through a piston cylinder, an electric push rod, a gear and rack mechanism, a screw rod mechanism or the like.

[0062] The photovoltaic cleaning robot disclosed in the embodiment of the utility model is provided with the self-charging assembly cleaning unit 300, through the movable arrangement of the cleaning member 303, the cleaning member 303 can reciprocate along the extension direction of the self-charging assembly 200 under the driving action of the walking driving device. In the embodiment with the moving member 301, the cleaning member 303 is arranged on the moving member 301, and after the self-charging assembly cleaning unit 300 is installed to the photovoltaic cleaning robot body 100 or the self-charging assembly 200, the cleaning member 303 can clean the self-charging assembly 200, along with the reciprocating movement of the moving member 301, the cleaning member 303 reciprocates along with the moving member 301, and then can clean each area of the self-charging assembly 200 along the extension direction of the self-charging assembly 200. The self-charging assembly cleaning unit 300 can be directly arranged on the photovoltaic cleaning robot body 100 or the self-charging assembly 200, or indirectly arranged on the photovoltaic cleaning robot body 100 or the self-charging assembly 200 through the corresponding support structure. The photovoltaic cleaning robot can clean the self-charging assembly 200 through the self-charging assembly cleaning unit 300 at any time, and is no longer limited by special places, and the cleaning times and frequency can be self-controlled, and the cleaning process of the self-charging assembly 200 does not affect the use of the photovoltaic cleaning robot.

[0063] AsFigures 3-6 As shown, in an embodiment of the utility model, the walking driving device can include a first transmission member 308, a second transmission member 307 and a first driving motor 306. The walking driving device can be suitable for cleaning of common photovoltaic modules and also suitable for cleaning of flexible modules.

[0064] The first transmission member 308 can be arranged on a first support member, which can be a first side frame of the self-charging module 200. The first support member can also be a support body connected to the photovoltaic cleaning robot body 100 and / or the self-charging module 200. That is, the first transmission member 308 can be directly arranged on the first side frame of the self-charging module 200, i.e., the side frame of the self-charging module 200 serves as the mounting base of the first transmission member 308, thereby reducing the space occupation and cost. The first transmission member 308 can also be indirectly arranged on the photovoltaic cleaning robot body 100 and / or the self-charging module 200 through the support body.

[0065] The first side frame can be a frame parallel to the extension direction of the self-charging module 200 (i.e., the long side of the self-charging module 200). The second transmission member 307 is in transmission cooperation with the first transmission member 308 and is connected to the moving member 301.

[0066] The first driving motor 306 is in transmission connection with one of the first transmission member 308 and the second transmission member 307 to drive the second transmission member 307 to reciprocate along the first transmission member 308. According to the specific structure of the first transmission member 308 and the second transmission member 307, the first driving motor 306 can drive one of them to rotate, so that the second transmission member 307 can generate linear displacement to drive the moving member 301 to reciprocate.

[0067] Specifically, the first transmission member 308 can include a rack fixed to the first support member, and the second transmission member 307 can include a gear 3071 engaged with the rack. The first driving motor 306 is in transmission connection with the second transmission member 307, and the second transmission member 307 is connected to the moving member 301 through the first driving motor 306, i.e., the first driving motor 306 is connected to the moving member 301, and the second transmission member 307 is connected to the output shaft of the first driving motor 306. The first driving motor 306 drives the second transmission member 307 to rotate, and the second transmission member 307 is engaged with the first transmission member 308, so that the second transmission member 307 can reciprocate along the extension direction of the first transmission member 308 while rotating, thereby driving the moving member 301 to reciprocate.

[0068] In addition, the first transmission member 308 can be a screw rod rotatably arranged on the first support member, the second transmission member 307 is a nut engaged with the rack, and the first driving motor 306 is arranged on the first support member and is in transmission connection with the first transmission member 308. The first driving motor 306 drives the first transmission member 308 to rotate, and the second transmission member 307 and the first transmission member 308 form a screw mechanism, so that the second transmission member 307 can reciprocate along the extension direction of the first transmission member 308, thereby driving the moving member 301 to reciprocate.

[0069] In order to improve the reliability of the moving process of the moving member 301, the walking driving device can further include an auxiliary guide mechanism, which includes an auxiliary guide rail 305 and a guide wheel 304.

[0070] The auxiliary guide rail 305 is arranged on the second support member, which can be the second side frame of the self-charging assembly 200. The second support member can also be a support body connected to the photovoltaic cleaning robot body 100 and / or the self-charging assembly 200. That is, the auxiliary guide rail 305 can be directly arranged on the second side frame of the self-charging assembly 200, that is, the side frame of the self-charging assembly 200 serves as the mounting basis of the auxiliary guide rail 305, which reduces the space occupation and cost. The auxiliary guide rail 305 can also be indirectly arranged on the photovoltaic cleaning robot body 100 and / or the self-charging assembly 200 through the support body.

[0071] The first side frame and the second side frame of the self-charging assembly 200 are opposite side frames. When the auxiliary guide rail 305 and the first transmission member 308 are both mounted using the side frames of the self-charging assembly 200, they can be respectively mounted on the opposite two side frames of the self-charging assembly 200, so that the auxiliary guide rail 305 and the first transmission member 308 are arranged in parallel.

[0072] The guide wheel 304 is in rolling cooperation with the auxiliary guide rail 305, and the moving member 301 includes a moving member body 3011 striding on the self-charging assembly 200 and a support portion 3012 arranged at both ends of the moving member body 3011. That is, both ends of the moving member body 3011 extend to the first side frame and the second side frame of the self-charging assembly 200, respectively. The support portion 3012 is arranged at both ends of the moving member body 3011 to facilitate the realization of the guide wheel 304 and the second transmission member 307, that is, the guide wheel 304 and the second transmission member 307 are arranged on the corresponding side support portion 3012 to facilitate the installation of the guide wheel 304 and the second transmission member 307. It should be noted that the support portion 3012 can also not be arranged, and the guide wheel 304 and the second transmission member 307 are respectively connected to both ends of the moving member body 3011.

[0073] In the embodiment, the two ends of the moving piece 301 are connected with the side frames of the self-charging assembly 200 through the guide wheels 304 and the second transmission pieces 307 respectively, so that the moving piece 301 can stably move along the two side frames of the self-charging assembly 200. Of course, the first support piece and the second support piece can also be arranged on the two sides of the self-charging assembly 200 respectively, and the moving piece 301 can also stably reciprocate along the self-charging assembly 200.

[0074] The auxiliary guide mechanism can further include a second driving motor 302, the second driving motor 302 is in transmission connection with the guide wheel 304, and the guide wheel 304 is arranged on the support part 3012 through the second driving motor 302. Specifically, the first driving motor 306 is fixed on one of the support parts 3012, the second driving motor 302 is fixed on the other support part 3012, and the guide wheel 304 can be arranged on the output shaft of the second driving motor 302. The second driving motor 302 can drive the guide wheel 304 to rotate, and the guide wheel 304 can realize the effect of driving the moving piece 301 to move by relying on the rolling friction force between the guide wheel 304 and the auxiliary guide rail 305. In the embodiment, driving force can be provided on both sides of the moving piece 301, so as to realize the movement of the moving piece 301, thereby avoiding the situation that the moving piece 301 is skewed and stuck due to the driving force on one side. It should be noted that the driving speeds of the second driving motor 302 and the first driving motor 306 should be the same or close. When the driving speeds on the two sides are different, the guide wheel 304 will slip and rotate idly along the auxiliary guide rail 305, so as to ensure that the speeds on the two sides are the same.

[0075] It should be noted that the second driving motor 302 can also not be arranged. In order to ensure the balance of the two ends of the moving piece 301, the moving piece 301 has the first driving motor 306 on one end, and if the second driving motor 302 is not arranged on the other end, a counterweight with a corresponding weight can be arranged to ensure the balance of the force.

[0076] Further, as shown in Figure 6 and Figure 7 The second transmission piece 307 can further include a gear 3071 engaged with the rack and limiting wheels 3072 arranged on the upper and lower sides of the gear 3071, and the two limiting wheels 3072 are located on the upper and lower sides of the rack respectively. In the embodiment, the limiting action of the two limiting wheels 3072 can prevent the gear 3071 from being disengaged from the rack in the direction of gravity, that is, the first driving motor 306 and the moving piece 301 are suspended on the self-charging assembly 200 by using the limiting wheels 3072.

[0077] Similarly, the outer circumferential surface of the guide wheel 304 has a limiting groove recessed towards the axis direction, and the auxiliary guide rail 305 cooperates with the limiting groove. The upper and lower edges of the limiting groove can also prevent the guide wheel 304 from being separated from the limiting groove in the direction of gravity. In this way, when the self-charging assembly 200 is arranged at a large inclination angle, a larger driving force can still be provided. The self-charging assembly 200 can be fixed on the support main beam 101 by means of the clamp 210, and can also be fixed on the support main beam 101 by other means.

[0078] Further, the first transmission member 308 is provided with a limiting body 309 at both ends. The limiting body 309 can limit the moving direction of the second transmission member 307, so as to prevent the second transmission member 307 from being separated from the first transmission member 308. The shape of the limiting body 309 is not limited in the embodiment, and can be any shape of limiting body 309 such as a plate-shaped member, a rod-shaped member, a block-shaped member, etc., as long as the movement of the second transmission member 307 can be limited.

[0079] Under normal circumstances, the first driving motor 306 drives the moving member 301 and the cleaning member 303 to reciprocate, so as to clean the self-charging assembly 200. When the second transmission member 307 reaches the limiting body 309, the torque of the first driving motor 306 increases due to the increased resistance, and the control system determines that the limit position is reached, and controls the first driving motor 306 to reverse rotation, so as to return reversely.

[0080] The cleaning member 303 can be composed of a support member and a cleaning member arranged on the support member. The cleaning member can be silica gel, a brush, etc. The support member can be provided with multiple rows of holes or waist holes. Different positions of the holes or waist holes at different heights are connected by fasteners, so as to be fixed on the moving member 301. In this way, the height of the cleaning member 303 can be adjusted, so as to control the compression amount of the cleaning member, and thus the best cleaning effect can be obtained.

[0081] The photovoltaic cleaning robot body 100 can include a support main beam 101, a walking wheel system 102 and a cleaning assembly 103. The self-charging assembly 200 can be arranged on the support main beam 101. The walking wheel system 102 includes a first walking mechanism and a second walking mechanism arranged at both ends of the support main beam 101 respectively, and the first walking mechanism and the second walking mechanism each include a walking wheel.

[0082] The cleaning assembly 103 is supported on the first walking mechanism and the second walking mechanism. During the walking of the photovoltaic cleaning robot along the photovoltaic assembly 400, the cleaning assembly 103 cleans the surface of the photovoltaic assembly 400 that passes by, so as to wipe off the dust deposited on the surface of the photovoltaic assembly 400.

[0083] In an embodiment of the utility model, the photovoltaic cleaning robot can further include a windproof system assembly, and the windproof system assembly includes a windproof system tail seat and a locking member.

[0084] The wind prevention system tail seat is arranged on the support main beam 101 of the self-charging assembly 200 or the photovoltaic cleaning robot body 100, and the wind prevention system tail seat is provided with a first insertion hole. It should be noted that when the photovoltaic cleaning robot moves to the parking position, the wind prevention system tail seat should not collide with the parking position wind prevention support on the parking position, and should be located on one side of the parking position wind prevention support.

[0085] The locking member moves with the cleaning member 303, which can be arranged on the moving member 301, or arranged on the cleaning member 303, or directly connected to the output end of the walking driving device. The locking member is used for insertion fitting with the first insertion hole, that is, the locking member corresponds to the first insertion hole. During the movement of the moving member 301, the locking member can be moved, and when it moves close to the wind prevention system tail seat, the locking member can be inserted into the first insertion hole. The moving member 301 is provided with a bolt fixing portion, and the locking member can be fixed on the bolt fixing portion. The bolt fixing portion can be a fixed sleeve, and the locking member is inserted into the fixed sleeve.

[0086] When the photovoltaic cleaning robot runs to the parking position, the first insertion hole corresponds to the second insertion hole on the parking position wind prevention support. It should be noted that the wind prevention system tail seat and the locking member should be located on both sides of the parking position wind prevention support, that is, the first insertion hole is inserted into the second insertion hole before being inserted into the first insertion hole, and then the photovoltaic cleaning robot is fixed on the parking position wind prevention support.

[0087] When the photovoltaic cleaning robot runs to the parking position, in order to prevent the strong wind from blowing the photovoltaic cleaning robot away from the parking position, the self-charging assembly cleaning unit 300 can be controlled to move towards the wind prevention system tail seat. The locking member will gradually approach the wind prevention system tail seat along with the self-charging assembly cleaning unit 300, until the locking member passes through the second insertion hole and the first insertion hole in turn, and then the photovoltaic cleaning robot is in a locked state. At this time, the movement of the photovoltaic cleaning robot is limited, and then the photovoltaic cleaning robot can be kept on the parking position. When the locking member is separated from the second insertion hole, the photovoltaic cleaning robot is in an unlocked state, and can freely walk without being limited by the locking. In the direction of the locking member, if the first insertion hole is located upstream of the second insertion hole, in order to make the locking member separate from the second insertion hole, the locking member needs to separate from the first insertion hole first, and then separate from the second insertion hole, so as to complete the unlocking. If the first insertion hole is located downstream of the second insertion hole, the locking member will first separate from the second insertion hole, and then the unlocking can be completed regardless of whether the locking member separates from the first insertion hole.
