Please refer to Figures 1-4 , a gear drive device for a photovoltaic cleaning robot in this implementation manner includes a fixed frame 100, a photovoltaic panel 200 and a housing 300.

[0028] The fixed frame 100 is composed of two relatively arranged steel pipes. A rack 110 is installed on the top of the fixed frame 100. Limiting holes 120 are formed in the inner wall of the fixed frame 100.

[0029] A plurality of photovoltaic panels 200 are evenly arranged inside the fixed frame 100. Fixing frames 210 are installed at positions corresponding to the bottom of the photovoltaic panels 200 and the limiting holes 120. A sliding plate 220 is slidably connected inside the fixing frame 210. A spring 230 is installed on the side wall of the sliding plate 220. A limiting rod 240 is installed on the other side wall of the sliding plate 220. The other end of the limiting rod 240 penetrates through the side wall of the fixing frame 210 and extends into the corresponding limiting hole 120. When the photovoltaic panel 200 needs to be installed inside the fixed frame 100, the sliding plate 220 is pulled to slide inside the fixing frame 210 and the spring 230 is compressed. The limiting rod 240 slides into the fixing frame 210 along with the sliding plate 220. At this time, the photovoltaic panel 200 is clamped downward into the fixed frame 100. After the photovoltaic panel 200 is moved to a position where the limiting rod 240 corresponds to the limiting hole 120, the spring 230 rebounds to push the sliding plate 220 and the limiting rod 240 to move towards the inner wall of the fixed frame 100. The limiting rod 240 extends into the corresponding limiting hole 120, and the photovoltaic panel 200 is limited and fixed inside the fixed frame 100.

[0030] The housing 300 is located on top of two fixing frames 100. The bottom of the housing 300 is open. A bidirectional motor 310 is installed inside the housing 300. Rotating rods 320 are installed at both output ends of the bidirectional motor 310. Gears 330 are installed at the other ends of the rotating rods 320. The gears 330 are engaged with the racks 110. A motor 340 is installed on the side wall of the housing 300. The output end of the motor 340 extends into the housing 300 and a cleaning roller 350 is installed. A cleaning cloth 351 is installed on the outer wall of the cleaning roller 350. Ventilation grooves 360 are formed at the top of the housing 300. A cleaning liquid sprayer 370 is installed inside the housing 300. A top fixing plate 380 is installed on the side wall of the housing 300. A first positioning roller 381 is rotatably connected to the side wall of the top fixing plate 380. The bottom of the first positioning roller 381 abuts against the top of the fixing frame 100. A side fixing plate 390 is installed on the outer wall of the housing 300. A second positioning roller 391 is rotatably connected to the side wall of the side fixing plate 390. The side end of the second positioning roller 391 abuts against the outer wall of the fixing frame 100. When in use, the bidirectional motor 310 is started to drive the rotating rods 320 and the gears 330 to rotate. When the gears 330 rotate, they are engaged with the racks 110 to push the housing 300 to move back and forth on top of the fixing frames 100 and the photovoltaic panels 200. While the housing 300 is moving, the motor 340 is started to drive the cleaning roller 350 and the cleaning cloth 351 to rotate, and the cleaning liquid sprayer 370 is started to spray the cleaning liquid onto the surface of the photovoltaic panel 200. When the cleaning cloth 351 rotates, it cleans the surface of the photovoltaic panel 200.
