[0023] like Figures 1 to 5As shown, a cleaning device of a photovoltaic cleaning robot in this embodiment includes a first cleaning mechanism 61, a second cleaning mechanism 62 and a water supply mechanism 63. The first cleaning mechanism 61 and the second cleaning mechanism 62 are respectively arranged at the front and rear of the housing 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 housing 1. The guide pipe 632 is made of metal material. The water supply pipe 631 is vertically arranged, and a water inlet 633 and a water outlet 634 are respectively arranged at both ends of the water supply pipe 631. The water outlet 634 is located at the bottom of the housing 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 slot can be used for connection. The diverter valve 635 is connected to the first cleaning mechanism 61 and the second cleaning mechanism 62 respectively. 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 inlet water port 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 is introduced into the first and second cleaning mechanisms through the two joints of the diverter valve 635 through the water pipe, 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 move with 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 back to improve the cleaning effect.

[0024] In this embodiment, the water supply pipe 631 is passed through 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 and the water supply pipe 631 can be vertically arranged and firmly positioned. 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 be connected to the water supply pipe after passing through the opening portion 636. 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.

[0025] 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 flow passes 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, so as to directly spray 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.

[0026] A cleaning device of a photovoltaic cleaning robot in this embodiment can distribute water flow to the front and rear parts, perform two flushings at the front and back, 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.
