Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application and are not used to limit the present application. In the present application, unless otherwise stated, the directional words used, such as "up", "down", "left", and "right", generally refer to the up, down, left, and right of the device in actual use or working state, specifically the drawing direction in the accompanying drawings.

[0030] The present application provides a traveling cleaning robot, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0031] See also Figure 1 The present application provides a traveling cleaning robot for cleaning inclined photovoltaic panels. When a plurality of photovoltaic panels are arranged to form a photovoltaic panel array, metal frames are provided at the edges of adjacent photovoltaic panels. In the present application, the photovoltaic panel array is formed by arranging one or two photovoltaic panels into a unit along their length, and then arranging the above units along the width direction of the photovoltaic panel.

[0032] See also Figure 1 The traveling cleaning robot includes a frame 100, a cleaning roller brush 200, and two groups of traveling devices. The side of the frame 100 in the length direction is defined as a cleaning side, and the side of the frame 100 in the width direction is defined as a mounting side. The length of the cleaning side is adapted to the width of at least one photovoltaic panel. In the present application, the length of the cleaning side matches the unit formed by the photovoltaic panel arranged in the length direction, so that when the traveling cleaning robot travels in the width direction of the photovoltaic panel, it can clean the entire photovoltaic panel array, avoiding the traveling cleaning robot from turning back and forth, thereby improving the cleaning efficiency.

[0033] See also Figure 1 The two cleaning sides of the frame 100 are respectively provided with cleaning roller brushes 200, which can not only improve the cleaning effect of the photovoltaic panel array, but also facilitate the cleaning of the photovoltaic panel in different directions, avoiding manual adjustment of the cleaning robot when cleaning in the reverse direction. The two cleaning roller brushes 200 are rotatably connected to the frame 100, so that the cleaning roller brushes 200 can be adapted to photovoltaic panels in various assembly scenarios, thereby ensuring the cleaning effect.

[0034] See also Figure 1 and Figure 2 The vehicle frame 100 includes a vehicle body main board 110, two vehicle body side panels 120, two first mounting strips 130, two second mounting strips 140 and at least one reinforcing frame 150, wherein the side of the vehicle body main board 110 in the length direction is a cleaning side, and the side of the vehicle body main board 110 in the width direction is a mounting side. The two vehicle body side panels 120 are respectively mounted to the two side ends of the vehicle body main board 110 by fastening screws, so that the two vehicle body side panels 120 are located at the mounting side of the vehicle body main board 110.

[0035] The central axes of the two first mounting bars 130 are parallel and are respectively fixed to the two clean sides of the vehicle body main board 110. The central axes of the two second mounting bars 140 are parallel to the central axes of the first mounting bars 130, and the second mounting bars 140 are correspondingly arranged below the first mounting bars 130, so that the four corners of the reinforcement frame 150 can be respectively connected to the above two first mounting bars 130 and the two second mounting bars 140, and the top of the reinforcement frame 150 is fixed to the lower surface of the vehicle body main board 110 by fastening screws.

[0036] The reinforcing frame 150 can connect the first mounting bar 130, the second mounting bar 140 and the vehicle body main board 110 into a whole, thereby increasing the strength and stability of the vehicle frame 100. At the same time, the reinforcing frame 150 can apply a supporting force to the vehicle body main board 110, so that the vehicle body main board 110 is not easy to bend and deform, thereby increasing the stability of the traveling cleaning robot during cleaning. In this embodiment, the vehicle frame 100 includes more than two reinforcing frames 150, and the multiple reinforcing frames 150 are arranged along the cleaning side direction.

[0037] See also Figure 2 , Figure 3 and Figure 5 , two sets of traveling devices are respectively connected to the mounting sides of both sides of the frame 100, so as to use the two sets of traveling devices to drive the frame 100 to clean the surface of the photovoltaic panel. Each set of traveling devices includes more than two rollers 310 and corresponding belt transmission pairs 320, and the multiple rollers 310 are rotatably connected to the body side panels 120 of the frame 100 through rolling bearings. The belt transmission pair includes a driving motor, more than two transmission wheels and a transmission belt, each transmission wheel is connected to the end of a roller 310, and the above-mentioned driving motor is electrically connected to any transmission wheel. The transmission belt is sleeved on the outside of the multiple transmission wheels, so that the driving motor can use the transmission belt to drive all the rollers 310 to rotate synchronously, so that the traveling device can be used to drive the traveling cleaning robot to clean along the cleaning route.

[0038] See also Figure 2-Figure 5At least one first limiting column 400 and at least one second limiting column 500 are respectively provided below the two mounting sides of the frame 100. The first limiting column 400 and the second limiting column 500 are rotatably connected to the bottom of the vehicle body side panel 120. At the same time, the central axis of the first limiting column 400 is parallel to the central axis of the second limiting column 500. When the traveling cleaning robot is placed on the surface of the photovoltaic panel array, the first limiting column 400 and the second limiting column 500 can respectively abut against the opposite frames of the upper and lower sides of the photovoltaic panel.

[0039] The central axis of the roller 310 is perpendicular to the central axis of the first limiting column 400. When the roller 310 moves along the surface of the photovoltaic panel, the outer side wall of the first limiting column 400 and the outer side wall of the second limiting column 500 can abut against the relative frame of the photovoltaic panel, thereby preventing the traveling cleaning robot from separating from the tilted photovoltaic panel. At the same time, the first limiting column 400 and the second limiting column 500 can roll synchronously based on the traveling cleaning robot, thereby reducing the friction between the first limiting column 400, the second limiting column 500 and the frame of the photovoltaic panel during the movement.

[0040] See also Figure 2-Figure 5 Since the central axis of the roller 310 is perpendicular to the central axis of the second limiting column 500, there is a minimum vertical distance between the end surface of the roller 310 facing the second limiting column 500 and the outer wall of the second limiting column 500, and the minimum vertical distance is greater than or equal to the width of the frame. When the traveling cleaning robot travels on the surface of the photovoltaic panel, the roller 310 is pressed against the surface of the photovoltaic panel and moves close to the upper and lower frames of the photovoltaic panel. At the same time, the second limiting column 500 can abut against the frame of the photovoltaic panel. Since the minimum vertical distance is greater than or equal to the width of the frame, the roller 310 can be prevented from interfering with the frame during the movement.

[0041] See also Figure 2-Figure 5 A first mounting seat 600 and a second mounting seat 700 are respectively provided at the body side panels 120 at both ends of the frame 100. The above-mentioned multiple first limiting columns 400 are connected to the first mounting seat 600, and the multiple second limiting columns 500 are connected to the second mounting seat 700 to facilitate the assembly and maintenance of the traveling cleaning robot.

[0042] See also Figure 2-Figure 4 The first mounting seat 600 includes a first mounting arm 610 and a first mounting plate 620 that are vertically connected. One end of the first mounting arm 610 is connected to a vehicle body side panel 120 by a fastening screw, and the other end thereof is vertically connected to the surface of the first mounting plate 620, and the above-mentioned first mounting plate 620 is arranged in a direction away from the frame 100.

[0043] See also Figure 4 and Figure 5At least one adjustment slot is provided on the first mounting plate 620, and the first limiting posts 400 correspond to the adjustment slots one by one. Each adjustment slot includes a transverse slot 621 and at least one mounting hole 622, and the transverse slot 621 is provided along the direction of the cleaning side, so that the first limiting post 400 can be inserted into the transverse slot 621 and slide along the direction of the transverse slot 621, thereby adjusting the distance between the first limiting post 400 and the second limiting post 500.

[0044] Multiple mounting holes 622 are arranged at equal intervals along the direction of the cleaning side. The mounting holes 622 are arc-shaped or semicircular, and each mounting hole 622 is connected to the transverse groove 621, so that the first limiting column 400 inserted into the transverse groove 621 can slide into a mounting hole 622, and the first limiting column 400 can be relatively fixed to the first mounting plate 620 by tightening screws.

[0045] The installation position of the first limiting column 400 can be adjusted by using the multiple installation holes 622 to change the distance between the first limiting column 400 and the second limiting column 500, so that the traveling cleaning robot can be adapted to photovoltaic panels of various specifications.

[0046] See also Figure 2 and Figure 5 The second mounting seat 700 includes a second mounting arm 710 and a second mounting plate 720 connected vertically. One end of the second mounting arm 710 is connected to the other opposite vehicle body side panel 120 by fastening screws, and the other end thereof is vertically connected to the upper surface of the second mounting plate 720. The lower surface of the second mounting plate 720 is connected to a clamping plate 730 by fastening screws. The clamping plate 730 is L-shaped, and the end of the clamping plate 730 can extend below the vehicle frame 100. When the traveling cleaning robot is placed above the photovoltaic panel, the clamping plate 730 can be attached to the lower surface of the photovoltaic panel, thereby further increasing the clamping force between the traveling cleaning robot and the photovoltaic panel, and improving the safety and stability during traveling.

[0047] In the present application, when the traveling cleaning robot is placed on the photovoltaic panel array, the first limiting post 400 abuts against the upper frame of the photovoltaic panel, and the second limiting post 500 abuts against the lower frame of the photovoltaic panel. Since the photovoltaic panel is arranged at an angle, and the card plate 730 is connected to the lower surface of the photovoltaic panel by carding, the cleaning robot can be prevented from flipping over, detaching, etc. during the traveling process. At the same time, the first limiting post 400 can adjust its installation position according to the specifications of the photovoltaic panel, so the first limiting post 400 abuts against the upper frame of the photovoltaic panel to facilitate the user to adjust.

[0048] See also Figure 3 and Figure 6The first limiting column 400 includes a first fixing column 410 and a first sleeve 420. The top end of the first fixing column 410 is connected to the bottom of a vehicle side panel 120 through a first mounting seat 600. The first sleeve 420 is rotatably mounted on the outer wall of the first fixing column 410 through a rolling bearing so that the first limiting column 400 can roll along the frame of the photovoltaic panel.

[0049] The first sleeve 420 is provided with a first weight-reducing cavity 421 along its axial direction, and at least one first reinforcing rib 430 is arranged in the first weight-reducing cavity 421. The first reinforcing rib 430 is arranged along the radial direction of the first sleeve 420, and its two ends are respectively fixed to the inner wall of the first weight-reducing cavity 421, so as to reduce the weight of the first limiting column 400 and maintain the strength of the first limiting column 400, thereby improving the stability of the traveling cleaning robot during cleaning.

[0050] See also Figure 6 The outer wall of the first sleeve 420 is provided with a first anti-skid sleeve 440. In this embodiment, the material of the first anti-skid sleeve 440 is preferably rubber or silicone. The first anti-skid sleeve 440 is provided with a plurality of anti-skid grooves along the axial direction, so as to prevent the first limit column 400 from rigidly contacting with the frame of the photovoltaic panel, and has a certain protective effect on both the first limit column 400 and the photovoltaic panel; in addition, the anti-skid sleeve and the anti-skid grooves can prevent the first limit column 400 from slipping when contacting, and can increase the safety and stability during travel.

[0051] See also Figure 5 and Figure 7 The second limiting column 500 includes a second fixed column 510 and a second sleeve 520. The top end of the second fixed column 510 is connected to the bottom of another vehicle side panel 120 through a second mounting seat 700. The second sleeve 520 is rotatably mounted on the outer wall of the second fixed column 510 through a rolling bearing so that the second limiting column 500 can roll along the frame of the photovoltaic panel.

[0052] The second sleeve 520 is provided with a second weight-reducing cavity 521 along its axial direction, and at least one second reinforcing rib 530 is arranged in the second weight-reducing cavity 521. The second reinforcing rib 530 is arranged along the radial direction of the second sleeve 520, and its two ends are respectively fixed to the inner wall of the second weight-reducing cavity 521, so as to reduce the weight of the second limiting column 500 and maintain the strength of the second limiting column 500, thereby improving the stability of the traveling cleaning robot during cleaning.
