[0056] The core of the utility model lies in providing a self -charging subassembly cleaning unit, and the cleaning can be carried out according to demand, and the fixed place is not limited;

[0057] Another core of the utility model lies in providing a photovoltaic cleaning robot and photovoltaic system with the self -charging subassembly cleaning unit.

[0058] Hereinafter, with reference to the attached drawings, the embodiment is explained. In addition, the embodiment shown below does not have any limiting effect on the utility model content recorded in the claim. In addition, the constitution represented in the following embodiment is not limited to the solution necessary as the utility model recorded in the claim. It should be noted that, for convenience of description, only the part related to the utility model is shown in the drawing. In the case of no conflict, the embodiment in the utility model and the features in the embodiment can be combined with each other.

[0059] AsFigure 1 As shown in the utility model embodiment, the self-charging assembly cleaning unit 300 is used for cleaning the self-charging assembly 200 installed on the photovoltaic cleaning robot body 100, and the self-charging assembly 200 is used for charging the storage battery of the photovoltaic cleaning robot body 100.

[0060] Specifically, as shown in the utility model embodiment, Figures 2-5 As shown in the utility model embodiment, the self-charging assembly cleaning unit 300 includes a sliding piece 301, a cleaning piece 303 and a walking driving device. The sliding piece 301 is used for slidingly fitting the photovoltaic cleaning robot body 100 or the self-charging assembly 200 along the extension direction of the self-charging assembly 200, so that when the sliding piece 301 reciprocally slides, different areas of the self-charging assembly 200 can be gradually covered.

[0061] The cleaning piece 303 is arranged on the sliding piece 301 and is used for cleaning the self-charging assembly 200. The cleaning piece 303 can be a brush type component, as long as it can remove dust and other impurities on the surface of the self-charging assembly 200 through relative friction with the self-charging assembly 200. It should be noted that the cleaning piece 303 cannot cover all areas of the self-charging assembly 200 in the static state, and it needs to gradually clean each area of the self-charging assembly 200 by moving.

[0062] Taking the extension direction of the self-charging assembly 200 as the first direction and the direction perpendicular to the first direction as the second direction, for example, the sliding piece 301 can drive the cleaning piece 303 to reciprocally move along the first direction (for example, move along the length direction of the self-charging assembly 200), and the cleaning piece 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). So that through the movement of the cleaning piece 303, all areas 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, it is allowed that part of the area of the self-charging assembly 200 cannot be cleaned due to avoiding interference components, that is, in the embodiment, the cleaning piece 303 is not limited to covering all areas of the self-charging assembly 200 by moving.

[0063] The walking driving device is used for driving the sliding piece 301 to reciprocate along the photovoltaic cleaning robot body 100. In the embodiment, the walking driving device can be arranged on the sliding piece 301, or arranged on the photovoltaic cleaning robot body 100 or the self-charging assembly 200. The arrangement position of the walking driving device is not limited in the embodiment, as long as the sliding piece 301 can be driven to reciprocate along the photovoltaic cleaning robot body 100. If the walking driving device is arranged on the sliding piece 301, the walking driving device can be a wheel system driving device, that is, the sliding piece 301 is driven to move through a walking wheel. If the walking driving device is arranged on the photovoltaic cleaning robot body 100, the walking driving device can be a push-pull type driving device, that is, the sliding piece 301 is driven to move through a piston cylinder, an electric push rod or the like.

[0064] The self-charging assembly cleaning unit 300 is slidably arranged on the photovoltaic cleaning robot body 100 or the self-charging assembly 200, so that the sliding piece 301 can reciprocate along the extension direction of the self-charging assembly 200 under the driving action of the walking driving device. The cleaning piece 303 is arranged on the sliding piece 301, and after the self-charging assembly cleaning unit 300 is installed on the photovoltaic cleaning robot body 100 or the self-charging assembly 200, the cleaning piece 303 can be attached to the self-charging assembly 200. With the reciprocating movement of the sliding piece 301, the cleaning piece 303 reciprocates with the sliding piece 301, and then can clean each area of the self-charging assembly 200 along the extension direction of the self-charging assembly 200.

[0065] 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 other support bodies. 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 to a special place. The cleaning frequency and times can be automatically controlled, and the cleaning process of the self-charging assembly 200 does not affect the use of the photovoltaic cleaning robot.

[0066] Taking the walking driving device arranged on the sliding piece 301 as an example, the walking driving device can include a driving motor 305 and a walking wheel 304 in the embodiment. The driving motor 305 is arranged on the sliding piece 301, and is fixed on the sliding piece 301 through a fastener. Of course, the driving motor 305 can be installed on the sliding piece 301 through other installation modes. The installation mode is not limited in the embodiment, as long as the sliding piece 301 can bear the driving motor 305 through the connection of the two, and the driving motor 305 can be driven to move with the sliding piece 301 during the movement of the sliding piece 301, so as to ensure the continuous output of the driving force to the sliding piece 301.

[0067] The walking wheel 304 is drivingly connected to the output shaft of the driving motor 305, and is used for walking along the photovoltaic cleaning robot body 100. The walking wheel 304 can be directly fixed on the motor shaft of the driving motor 305. It should be noted that, since the walking speed of the self-charging component cleaning unit cannot be too fast, a driving motor 305 with low and / or adjustable rotating speed, such as a driving motor 305 with a speed reducer, should be selected to enable the sliding member 301 to move along the photovoltaic cleaning robot body 100 at a suitable moving speed. The walking manner of the walking wheel 304 can be the same as that of the walking trolley, i.e., the sliding member 301 is driven to move by the friction force between the walking wheel 304 and the photovoltaic cleaning robot body 100 at the contact position.

[0068] As shown in Figure 2 and Figure 3 , when the self-charging component 200 is arranged on the support main beam 101 of the photovoltaic cleaning robot body 100, the sliding member 301 is sleeved on the support main beam 101, and the cleaning member 303 can be arranged on the inner wall of the sliding member 301 and / or the end surface of at least one end of the sliding member 301. The specific arrangement position of the cleaning member 303 is not limited in the embodiment, as long as the cleaning of the self-charging component 200 can be realized.

[0069] The self-charging component 200 can be arranged on the upper surface of the support main beam 101, the sliding member 301 is sleeved on the support main beam 101 and reciprocally moves along the support main beam 101, and when moving to the corresponding region of the self-charging component 200 on the support main beam 101, the corresponding region of the self-charging component 200 is cleaned by the cleaning member 303 arranged on the inner wall of the sliding member 301.

[0070] Further, in order to improve the stability of the walking wheel 304 when walking, the support main beam 101 has a walking track groove 1011 (as shown in Figure 4 , as shown in Figure 5 , the walking wheel 304 extends into the space surrounded by the sliding member 301, and is at least limited in the walking track groove 1011 in the direction of gravity. The walking track groove 1011 needs to have a limiting function for the walking wheel 304, so that after the walking wheel 304 is matched in the walking track groove 1011, the walking wheel 304 will not be separated from the walking track groove 1011 under the action of gravity. Specifically, the walking wheel 304 is matched in the walking track groove 1011 and is supported by the side wall of the walking track groove 1011, so part of the structure of the side wall of the walking track groove 1011 can provide support for the walking wheel 304. For example Figure 4In the shown scheme, the walking track groove 1011 is in a tapered structure, and the side wall at the tapered part can provide support for the walking wheel 304 to prevent the walking wheel 304 from leaving the walking track groove 1011, and the walking wheel 304 can only enter or leave the walking track groove 1011 from the end of the walking track groove 1011.

[0071] In an embodiment of the utility model, the walking track groove 1011 is a groove with an opening facing downward, and the walking track groove 1011 is arranged opposite to the self-charging assembly 200, the self-charging assembly 200 is arranged on the upper side of the support main beam 101, and the walking track groove 1011 is arranged on the lower side of the support main beam 101.

[0072] The rolling surface of the walking wheel 304 is attached to the side wall of the walking track groove 1011, and for example, the walking track groove 1011 is symmetrical in the vertical direction, and the axis of the walking wheel 304 is in the vertical direction. It should be noted that the photovoltaic assembly is usually arranged at a certain angle, so when the photovoltaic cleaning robot is applied to the photovoltaic assembly, the axis of the walking wheel 304 has a certain angle with the vertical direction, and the angle is the same as the inclination angle of the photovoltaic assembly. In this embodiment, the walking track groove 1011 is arranged on the lower side of the support main beam 101, so that the installation of the self-charging assembly 200 is not affected by the walking track groove 1011.

[0073] Further, the rolling surface of the walking wheel 304 is attached to both side walls of the walking track groove 1011, so that the walking wheel 304 has better installation stability. However, since the rolling surface of the walking wheel 304 is attached to both side walls of the walking track groove 1011, the friction force direction of the walking wheel 304 acting on the two side walls of the walking track groove 1011 is opposite, that is, the friction force on one side will drive the self-charging assembly cleaning unit 300 to move forward, and the friction force on the other side will drive the self-charging assembly cleaning unit 300 to move backward, resulting in that the walking wheel 304 is idling in place, and the self-charging assembly cleaning unit 300 neither moves forward nor backward.

[0074] Therefore, in this embodiment, the friction coefficient of one of the two side walls of the walking track groove 1011 is designed to be greater than the friction coefficient of the other, that is, the friction coefficients of the walking track groove 1011 are designed to be different. For example, one side wall can be designed as a rough surface, and the other side wall can be designed as a smooth surface, so that when the walking wheel 304 contacts the rough surface, the walking wheel 304 has a greater friction force, and when the walking wheel 304 contacts the smooth surface, the walking wheel 304 has a relatively small friction force, so that the friction forces of the two sides are different, and the walking wheel 304 will walk along the side with a larger friction force, and the walking wheel 304 will slip and idle on the side with a smaller friction force.

[0075] In addition, the rolling surface of the walking wheel 304 can also only be in contact with one side wall of the walking track groove 1011, and there is a gap between the rolling surface of the walking wheel 304 and the other side wall. For example, when the walking track groove 1011 is horizontally arranged (that is, the direction from the groove bottom of the walking track groove 1011 to the opening is a horizontal direction or the included angle with the horizontal plane is less than 45°, that is, the inclination angle along the horizontal plane is not large), the bottom of the walking wheel 304 is in contact with the bottom side wall of the walking track groove 1011, and the bottom side wall of the walking track groove 1011 supports the walking wheel 304, so that the other side wall (that is, the top side wall) does not need to be in contact, and the cooperation between the walking wheel 304 and the walking track groove 1011 can also be ensured.

[0076] In the embodiment, the driving motor 305 is suspended on the lower side of the sliding member 301, the walking track groove 1011 is located on the lower side of the support main beam 101, and the axis of the walking wheel 304 is perpendicular to the extension direction of the support main beam 101. In the embodiment, the driving motor 305 is suspended on the lower side of the sliding member 301, that is, the driving motor 305 is arranged in the space between the cleaning unit of the photovoltaic cleaning robot body 100 and the support main beam 101. The space is generally not arranged with other components, so that interference with other components is avoided. In addition, the driving motor 305 is suspended and arranged, and compared with the arrangement on the side of the support main beam 101, the cantilever beam structure is not formed, so that the reliability is higher.

[0077] As shown in Figure 1 The utility model discloses a photovoltaic cleaning robot, photovoltaic cleaning robot includes photovoltaic cleaning robot body 100, self -charging assembly 200 and self -charging assembly cleaning unit 300. Wherein, photovoltaic cleaning robot body 100 photovoltaic cleaning robot's main structure is used for completing the cleaning (such as Figure 7 As shown in

[0078] Self -charging assembly 200 sets up on photovoltaic cleaning robot body 100, is used for charging the power supply of photovoltaic cleaning robot body 100, and self -charging assembly 200 can be the flexible photovoltaic assembly arranged on the support main beam 101. The flexible photovoltaic assembly can utilize the external contour of the support main beam 101 and be directly attached to the surface of the support main beam 101. When the support main beam 101 is a curved beam, the self -charging assembly 200 can also be wrapped on the support main beam 101 in a curved shape. Correspondingly, the cleaning piece 303 should also be designed to be able to attach to the curved structure of the self -charging assembly 200. The self -charging assembly 200 can be fixed on the support main beam 101 by means of back adhesive bonding, clamp fixing or riveting.

[0079] The support main beam 101 can be a hollow beam, and parts of the photovoltaic cleaning robot body 100 can be mounted by using the hollow structure of the support main beam 101. For example, at least part of the wiring harness of the photovoltaic cleaning robot body 100 can be arranged in the support main beam 101. In the embodiment, by arranging part or all of the wiring harness in the cavity of the support main beam 101, the accommodation of the wiring harness can be achieved, and the wiring harness can be prevented from being pulled off and causing electrical connection problems such as open circuit due to exposure.

[0080] The self-charging component cleaning unit 300 is the self-charging component cleaning unit 300 disclosed in the above embodiment. Since the self-charging component cleaning unit 300 is provided, all the technical effects of the self-charging component cleaning unit 300 are achieved, and details are not repeated here.

[0081] As shown in Figure 1 In a specific embodiment of the utility model, the photovoltaic cleaning robot can further include a windproof system assembly 400, and the windproof system assembly 400 includes a windproof system tail seat 402 and a locking piece 401.

[0082] As shown in Figure 6 The windproof system tail seat 402 is arranged on the support main beam 101 of the photovoltaic cleaning robot body 100, and the windproof system tail seat 402 is provided with a first jack 4021. It should be noted that when the photovoltaic cleaning robot moves to the parking position, the windproof system tail seat 402 should not collide with the parking position windproof support 600 on the parking position, and should be located on one side of the parking position windproof support 600.

[0083] The locking piece 401 can be arranged on the sliding piece 301 or the cleaning piece 303, as long as it can move with the sliding piece 301 and the cleaning piece 303. The locking piece 401 is used for plug-in cooperation with the first jack 4021, that is, the locking piece 401 corresponds to the first jack 4021. During the movement of the sliding piece 301, the locking piece 401 can be moved, and when it is moved close to the windproof system tail seat 402, the locking piece 401 can be inserted into the first jack 4021. The sliding piece 301 is provided with a latch fixing portion 302, and the locking piece 401 can be fixed on the latch fixing portion 302. The latch fixing portion 302 can be a fixed sleeve, and the locking piece 401 is plug-in in the fixed sleeve.

[0084] It should be noted that the shape of the locking piece 401 is not limited to Figure 3 The rod-shaped structure shown, which can also be a block-shaped structure, a plate-shaped structure, etc., as long as it can cooperate with the first jack 4021.

[0085] When the photovoltaic cleaning robot moves to the stopping position, the first socket 4021 corresponds to the second socket 601 on the windproof bracket 600 at the stopping position. It should be noted that the tailstock 402 and the locking element 401 of the windproof system should be located on both sides of the windproof bracket 600 at the stopping position. That is, the second socket 601 is inserted before the first socket 4021 is inserted, thereby achieving the effect of fixing the photovoltaic cleaning robot to the windproof bracket 600 at the stopping position.

[0086] like Figure 7 As shown, when the photovoltaic cleaning robot reaches the stopping position, to prevent strong winds from blowing it away, the self-charging component cleaning unit 300 can be controlled to move towards the windproof system tailstock 402. The locking member 401 will follow the self-charging component cleaning unit 300 and gradually approach the windproof system tailstock 402 until the locking member 401 passes through the second socket 601 and the first socket 4021 in sequence, at which point the photovoltaic cleaning robot is in a locked state. At this time, the movement of the photovoltaic cleaning robot is restricted, thus keeping it in the stopping position. When the locking member 401 disengages from the second socket 601, the photovoltaic cleaning robot is in an unlocked state and can move freely without being restricted by the lock. Along the exit direction of the locking member 401, if the first socket 4021 is located upstream of the second socket 601, in order for the locking member 401 to disengage from the second socket 601, the locking member 401 needs to disengage from the first socket 4021 first, and then disengage from the second socket 601 to complete the unlocking; if the first socket 4021 is located downstream of the second socket 601, the locking member 401 will disengage from the second socket 601 first, and the unlocking can be completed regardless of whether the locking member 401 disengages from the first socket 4021.

[0087] In this embodiment, the locking member 401 is set on the self-charging component cleaning unit 300 by utilizing the mobility of the self-charging component cleaning unit 300, and the wind-resistant locking and unlocking functions are realized by utilizing the mobility of the self-charging component cleaning unit 300.

[0088] like Figures 8-10 As shown, when the self-charging component 200 needs cleaning, the self-charging component cleaning unit 300 is controlled to move towards the self-charging component 200, at least from one end to the other along the extension direction of the self-charging component 200.
