The first cleaning mechanism 61 is arranged corresponding to the brush assembly 5, located at the front end of the housing, and can spray the cleaning liquid in advance, and then clean it through the brush assembly 5. The second cleaning mechanism 62 is arranged corresponding to the drive assembly 3, which can clean the drive assembly 3 and rinse the panel again. In the above technical solution, when the photovoltaic mobile cleaning device starts cleaning, the power motor 4 drives the drive assembly 3 to move on the photovoltaic panel, and the brush assembly 5 brushes the photovoltaic panel. The cleaning water is introduced through the water supply mechanism 63, and then flows to the first and second cleaning mechanisms respectively, so that it can be rinsed twice before and after, thereby improving the cleaning effect. In addition, through the structural design of the housing, the overall weight can be reduced and the mobility can be improved.

[0040] In this embodiment, the housing 1 is provided with a first receiving portion 15 and a second receiving portion 16 for receiving the battery 2 and the control module 7, respectively. The control module 7 and the battery 2 are respectively arranged on both sides of the bracket 14, so that the weight distribution on the front and rear sides of the photovoltaic mobile cleaning device is more balanced and the movement is more stable.

[0041] In this embodiment, the driving assembly 3 is located outside the crossbeam 11, and a cover plate 20 is provided above the driving assembly 3, so that the driving assembly 3 is better protected. The driving assembly 3 includes a driving wheel 31 and a driven wheel 32, and the two driving wheels 31 are respectively connected to the power motor 4. The driving wheel 31 and the driven wheel 32 are sleeved with a transmission belt 33, and the driving wheel 31 drives the transmission belt 33, so that the driven wheel 32 moves synchronously. A follower mechanism 34 is provided between the driving wheel 31 and the driven wheel 32, and the follower mechanism 34 can make the photovoltaic cleaning vehicle more stable when the mobile device climbs a slope or encounters an obstacle. The follower mechanism 34 is located between the upper belt body 331 and the lower belt body 332 of the transmission belt 33, and the follower mechanism 34 includes a fixed plate 341 and a floating part 342, and a plurality of floating parts 342 are arranged on the fixed plate 341 at intervals along the direction of the transmission belt 33. The fixed plate 341 is provided with a strip hole 343, and correspondingly, the shell also has a corresponding strip hole 343'. The floating part 342 is provided with a connecting rod 344 inserted in the strip hole 343, and the connecting rod 344 can slide or rotate in the strip hole 343. The floating part 342 includes a mounting seat 345 and a wheel group 346. Several wheel groups 346 are arranged on the mounting seat 345 at intervals. Several wheel groups 346 are arranged along the direction of the transmission belt. The lower part of the wheel group 346 abuts against the lower belt body 332, and the mounting seat 345 is spaced from the upper plate body 347 of the fixed plate 341. In the above technical solution, when encountering an obstacle, the transmission belt presses on the obstacle. Through the floating or rotation of the floating part 342, it is easy to cross the obstacle. At the same time, the lower belt body 332 can increase the contact area with the ground and improve the movement stability. Through the above technical solution, it is easy to move and cross obstacles for the photovoltaic cleaning vehicle, and improve the mobility of the photovoltaic cleaning vehicle. The photovoltaic cleaning vehicle of this embodiment has two sets of moving devices.

[0042] In this embodiment, the mounting seat 345 is provided with an elastic member 348, and the elastic member 348 is located between the mounting seat 345 and the upper plate 347, so that when the mounting seat 345 moves upward, the elastic member 348 can prevent the mounting seat 345 from colliding with the upper plate and being damaged. The elastic member 348 is made of polyurethane material. The upper plate 347 is provided with a connecting plate 3471 and a side plate 3472 on both sides, and the connecting plate 3471 is connected to the photovoltaic cleaning vehicle. The strip hole 343 is arranged on the side plate 3472, so that the upper plate 347 can be firmly connected to the photovoltaic cleaning vehicle.

Each wheel set 346 is provided with a plurality of rollers 3461, which are arranged in parallel and press against the lower belt body 332. In this embodiment, two sets of wheel sets 346 are provided, and the two sets of wheel sets 346 can move independently, and the rollers 3461 can roll independently, thereby enhancing the mobility. The transmission belt 33 has anti-skid grooves 333, which are arranged in a V-shaped interval, thereby further improving the anti-skid performance of the transmission belt.

[0043] like Figures 5 to 8 As shown, in this embodiment, the brush assembly 5 is connected to the crossbeam 11 through a swing assembly 8. Thus, when the brush assembly 5 encounters a raised portion, it can swing up and down relative to the housing 1 to adapt. The swing assembly 8 includes a fixed block 81, a connecting plate 82 and a knob 83. The fixed block 81 is connected to the housing 1 through a locking member 84. The fixed block 81 is provided with a matching hole 811. The connecting plate 82 is connected to the brush assembly 5. The connecting plate 82 is provided with a connecting hole 821 corresponding to the matching hole 811. A pin 85 is passed through the matching hole 811 and the connecting hole 821, so that the connecting plate 82 can rotate around the pin. The connecting plate 82 is also provided with an arc hole 822. The locking member 84 is passed through the arc hole 822, so that the locking member 84 can move relative to the arc hole 822. The knob 83 includes a rod body 831, which is threadedly connected to the connecting plate 82. One end of the rod body 831 is arranged opposite to the fixed block 81, and the other end is provided with an operating part 832, and the operating part 832 is located above the connecting plate 82. In the above technical solution, when the photovoltaic cleaning robot moves, the brush assembly 5 brushes the photovoltaic panel. When the brush assembly 5 encounters an obstacle, the brush assembly 5 is subjected to pressure, and the connecting plate 82 rotates around the pin shaft 85 and is guided by the arc hole 822. By rotating the operating part 832, the user can raise and lower the rod body 831, thereby adjusting the floating distance of the connecting plate 82. Through the above technical solution, the photovoltaic cleaning robot can adaptively adjust the position of the brush assembly according to the undulating state on the panel during the cleaning process, thereby improving the brushing effect and obstacle crossing ability.

[0044] In this embodiment, the connecting plate 82 is L-shaped, and a connecting hole 821 is provided on the side of the connecting plate 82. The upper surface of the connecting plate 82 is connected to the rod body 831, so that the operating part 832 is located at the top, which is convenient for user operation. The connecting plate 82 is provided with a nut 822, and the rod body 831 is threadedly connected to the nut 822, so that the rod body can be raised and lowered by rotating the rod body 831. In this embodiment, the brush assembly 5 includes a shell 51, and a brush motor 52 is provided on the shell 51. The brush motor 52 is arranged outside the shell 51, so that it can avoid being restricted by the shell 51 and adopt a brush motor 52 with stronger power. A brush 53 is provided below the shell 51, and the brush 53 is connected to the brush motor 52 through a side transmission mechanism 54. Through the above technical solution, the brush motor 52 drives the brush 53 to rotate through the side transmission mechanism 54. The brush motor 52 is provided with a protective cover 55, so that the protection of the brush motor 52 can be improved. The driving rod 521 of the brush motor 52 is parallel to the brush 53 and is located above the housing 51. The driving rod 521 is connected to the side transmission mechanism 54, and the side transmission mechanism 54 is driven by the driving rod 521. The side transmission mechanism 54 can adopt an existing belt transmission mechanism, which is a conventional technical means in the field and will not be described in detail. The housing 51 is provided with a support frame 56, and the driving rod 521 is inserted into the support frame 56. Since the driving rod 521 is relatively long, the rotation stability of the driving rod 521 can be improved by the support frame 56. Two groups of swing assemblies 8 are symmetrically arranged on the brush assembly 5, and the brush motor 52 is arranged between the two groups of swing assemblies, so that the brush assembly 5 can swing more smoothly and the center of gravity of the brush assembly 5 is closer to the middle.

[0045] like Figures 1 to 3 and Fig. 9 and Fig.10As shown, the first cleaning mechanism 61 and the second cleaning mechanism 62 are respectively arranged at the front and rear of the shell 1 of the photovoltaic cleaning robot. The first cleaning mechanism 61 and the second cleaning mechanism 62 are connected to the water supply mechanism 63. The water supply mechanism 63 includes a water supply pipe 631 and a guide pipe 632. The guide pipe 632 is connected to the water supply pipe 631. The water supply pipe 631 is rotatably arranged on the bracket 14. The guide pipe 632 is located above the shell 1. The guide pipe 632 is made of metal material. The water supply pipe 631 is vertically arranged, and the two ends of the water supply pipe 631 are respectively provided with a water inlet 633 and a water outlet 634. The water outlet 634 is located at the bottom of the shell 1. The water outlet 634 is provided with a diverter valve 635. The diverter valve 635 is rotatably connected to the water supply pipe 631. Existing connectors such as universal joints can be used, or an annular card groove can be used for connection. The diverter valve 635 is respectively connected to the first cleaning mechanism 61 and the second cleaning mechanism 62. In the above technical solution, the water pipe connected to the water tank is inserted into the guide pipe 632, and then connected to the water inlet 633 of the water supply pipe 631, so that the water in the water tank is introduced into the water supply pipe 631 through the water pipe. The water flows downward through the water supply pipe 631 and flows into the diverter valve 635 through the two joints of the diverter valve 635 through the water pipe to the first and second cleaning mechanisms, so that the front and rear parts of the photovoltaic cleaning robot can be cleaned. When the photovoltaic cleaning robot moves and turns, the water supply pipe 631 can follow it, so as not to affect the water supply. Through the above technical solution, the water flow can be distributed to the front and rear, and two flushings are performed in the front and rear to improve the cleaning effect.

[0046] In this embodiment, the water supply pipe 631 is inserted into the clamp block 64, and the notch portion 641 of the clamp block 64 is locked by a screw 65. The guide pipe 632 is sleeved on the water supply pipe 631 and connected to the clamp block 64 by a screw 66. Through the above technical solution, the guide pipe 632 can be vertically arranged with the water supply pipe 631 and firmly positioned at the same time. The clamp block 64 is a C-shaped clamping block, which can be easily installed and disassembled. The guide pipe 632 is provided with an opening portion 636, and the opening portion 636 faces upward. The water pipe can pass through the opening portion 636 and then connect to the water supply pipe. A water pipe seat 637 is provided at the position corresponding to the opening portion 636 to position the water pipe. The cross section of the guide pipe 632 is rectangular. In this embodiment, the water supply pipe 631 is inserted into the bearing 67, and the bearing 67 is arranged on the bracket 14, so that the water supply pipe 631 can rotate relative to the bearing. The first cleaning mechanism 61 includes a first conduit 611 and a first nozzle 612, and a plurality of first nozzles 612 are arranged at intervals on the first conduit 611. The second cleaning mechanism 62 includes a second conduit 621 and a second nozzle 622, and a plurality of second nozzles 622 are arranged at intervals on the second conduit 621. Through the above technical solution, the water flows through the first conduit 611 and the second conduit 621 and then sprays out through the first nozzle 612 and the second nozzle 622 respectively, thereby increasing the spraying range. The first nozzle 612 and the second nozzle 622 face downward, thereby directly spraying the ground. The first conduit 611 has a first joint 613, and the second conduit 621 has a second joint 623. The first joint 613 and the second joint 623 are connected to the diverter valve 635, so that the water flow of the diverter valve 635 can be introduced into the first and second conduits. A cleaning device of a photovoltaic cleaning robot in this embodiment can distribute the water flow to the front and rear parts, perform two flushings at the front and rear, and improve the cleaning effect; in addition, by connecting to an external water source, there is no need to set up a water storage device, which reduces the weight and can continuously supply water.

[0047] like Figure 2 and Figures 11 to 14As shown, the driving assembly 3 of this embodiment includes a driven wheel 32 and a tensioning mechanism 9, and the driven wheel 32 is connected to the crossbeam 11 through the tensioning mechanism 9. The tensioning mechanism 9 includes a sliding block 91, an adjusting member 92 and a limiting plate 93, wherein the sliding block 91 and the adjusting member 92 are respectively arranged on both sides of the crossbeam 11, and the connecting shaft 321 of the driven wheel 32 passes through the limiting plate 93, the crossbeam 11 and the sliding block 91 in sequence, and the connecting shaft 321 is located in the adjusting hole 111 of the crossbeam 11, and the adjusting hole 111 is arranged horizontally. The crossbeam 11 also has a guide hole 112 parallel to the adjusting hole 111, and the first fixing hole 931 of the limiting plate 93 and the second fixing hole 911 of the sliding block 91 are arranged corresponding to the guide hole 112 and connected by a locking member 94, and the locking member 94 can adopt an existing locking member such as a screw. The sliding block 91 is fixed on the connecting shaft 321, and the adjusting member 92 is arranged on the front frame 18 of the photovoltaic mobile cleaning device, and the adjusting member 92 is connected to the sliding block 91. In the above technical solution, a transmission belt 33 is arranged between the driven wheel 32 and the driving wheel 31, and the driving wheel 31 drives the transmission belt 33 and the driven wheel 32 to rotate. After the transmission belt 33 has been used for a period of time, it is easy to loosen, and the transmission belt 33 is tensioned by the tensioning mechanism. When tensioning, the locking member 94 is released, so that the limit plate 93, the sliding block 91 and the connecting shaft 321 are in a connected and movable state. The adjusting member 92 is operated, and the sliding block 91 is driven to slide by the adjusting member 92, so that the connecting shaft 321 slides along the adjusting hole 111, so that the driven wheel 32 moves and the transmission belt 33 is tensioned. After the adjustment is completed, the sliding block and the limit plate are locked by the locking member 94. Through the above technical solution, the driven wheel can be tensioned and positioned, which is convenient for operation.

[0048] In this embodiment, the front frame 18 is provided with a threaded member 181, and the adjusting member 92 is threadedly connected with the threaded member 181. The threaded member 181 is a nut welded on the front frame 18. The adjusting member 92 is a screw rod inserted in the threaded member 181. By rotating the adjusting member 92, the adjusting member 92 can be extended and retracted, thereby driving the sliding block 91 to move. The sliding block 91 has a slot 911, and the connecting shaft 321 is inserted in the sliding block 91. The slot 911 is locked by a bolt, and the bolt is inserted in the screw hole 912 of the sliding block 91. The contraction and release of the slot 911 can clamp or release the connecting shaft 321. The sliding block 91 is a C-shaped clamping block. The adjusting hole 111 and the guide hole 112 are both bar-shaped holes, so that they have a certain length, so that the connecting shaft can have a certain adjustment stroke therein. The guide holes 112 are arranged above and below the adjustment hole 111, and the limit plate 93 and the sliding block 91 are both provided with a plurality of first fixing holes 931 and second fixing holes 911, so that the sliding is smoother during adjustment and more stable during locking. The connecting shaft 321 has a step portion 322, and the size of the step portion 322 is larger than the size of the adjustment hole 111, so that when the connecting shaft 32 penetrates the adjustment hole 111, the step portion 322 is used for position limiting. Two sets of tensioning mechanisms 9 are symmetrically arranged on both sides of the crossbeam 11, so that the driven wheels on both sides can be adjusted independently.
