[0049] like Figure 3 as well as Figure 6 As shown, the box body 110 includes a first through hole 114, a second through hole 115, a first opening 116 and a second opening 117.

The water pressure formed by the nozzle can be used to flush stubborn stains on the photovoltaic panel array. The photovoltaic panel array is cleaned by flushing with high-pressure water flow and then by the bristles on the roller brush sleeve 214, thereby improving the cleaning efficiency of the cleaning robot.

[0053] like Figure 3-Figure 5 As shown, the water power transmission mechanism 100 further includes two first connecting members 170 , and the first connecting members 170 are respectively fixedly connected to two ends of the power output shaft 130 .

When the impeller 120 rotates, due to the power output shaft 130 The strip protrusion on the outer surface (not shown in the figure) is stuck in the second strip notch (not shown in the figure) on the inner surface of the sleeve 121, so the power output shaft 130 can rotate synchronously with the impeller 120. When the power output shaft 130 rotates, since the strip protrusion on the outer surface of the power output shaft 130 (not shown in the figure) is stuck in the first strip notch (not shown in the figure) on the inner surface of the first annular member 17, the first connecting member 170 can rotate synchronously with the power output shaft 130, and the rotation of the first connecting member 170 drives the roller brush sleeve 214 to rotate.

[0056] In the application scenario of this embodiment, for example, the cleaning robot and the water pump are started.

The water flows through the second channel 113 and flows out from the second opening 114. 17 flows out of the box body 110, and finally the water flow drops on the surface of the photovoltaic panel array. In the process of the water flow entering the second channel 113 from the first channel 112, the water flow impacts the blades 122, so that the impeller 120 rotates, and the rotation of the impeller 120 drives the power output shaft 130 to rotate, and the rotation of the power output shaft 130 drives the two first connecting members 170 to rotate, and the rotation of the two first connecting members 170 drives the two roller brush sleeves 214 to rotate synchronously, and the water flow dripping on the photovoltaic panel array is used to rinse the surface of the photovoltaic panel array, and the roller brush sleeve 214 rotates synchronously to clean the surface of the photovoltaic panel array.

[0057] The utility model discloses a water power transmission mechanism, a cleaning device and a cleaning robot. When the cleaning robot cleans the photovoltaic panel array, it is necessary to use water to rinse the photovoltaic panel array. The utility model replaces the traditional motor-driven roller brush sleeve with a water power-driven roller brush sleeve; the box body of the water power transmission mechanism is fixed to the middle of the two long frames of the rectangular frame, and each first connecting member is fixedly connected to one end of the power output shaft of the water power transmission mechanism; each second connecting member is rotatably installed to the inner side wall of a short frame, and the two ends of the roller brush sleeve are respectively sleeved on and fixed to the outer surface of a second connecting member and a first connecting member.
