Detailed Implementation

[0014] The following is in conjunction with the appendix Figure 1-15 The present invention will be described in further detail below.

[0015] A dual-axis steering photovoltaic panel cleaning robot includes a head unit 1, a tail unit 2, a body 3 connecting the two, photovoltaic panels 22, and a control box 4 mounted on the body 3, wherein: Both the head unit 1 and the tail unit 2 include a horizontal steering knuckle 5, a travel motor 6 distributed on the horizontal steering knuckle 5, and a commutator 7 shaft-connected to the travel motor 6; additionally, the head unit includes an axial steering knuckle 8; the commutator 7 is connected to a travel wheel 9 and a hanging wheel 10; the tail unit 2 also includes a brush motor 13, which is connected to the brush shaft 12 via a brush shaft universal joint 11; the exterior of the body 3 is provided with a photovoltaic panel connecting frame 14 connected to a photovoltaic panel 22, which is used to power the control box 4; the control box 4 is electrically connected to the travel motor 6 and the brush motor 13.

[0016] The axial steering joint 8 is used to adjust the tilt angle misalignment between two groups of photovoltaic panels in each row of photovoltaic panels in the photovoltaic power station to be cleaned. Specifically, the axial steering joint 8 located on the head 1 rotates around the axis of the fixed frame, thereby achieving axial rotation and solving the tilt angle misalignment problem of the photovoltaic panels in the photovoltaic power station. During this cleaning process, the brush motor 13 drives the brush shaft universal joint 11, which in turn drives the brush shaft 12 to rotate, and the brush shaft 12 drives the brush 16 to move, thus solving the cleaning problem. Furthermore, in the specific implementation process, it is ensured that one end of the head 1 or the tail 2 can achieve axial rotation, thereby achieving axial rotation on one side, and thus achieving the function of both achieving axial rotation and ensuring the stability of the machine body 3 during the cleaning process.

[0017] The horizontal steering knuckle 5 is used to adjust the misalignment between two sets of photovoltaic panels in each row of photovoltaic panels in a photovoltaic power station. Specifically, the horizontal steering knuckle 5 is movably connected to the axial steering knuckle 8 at the head of the machine via the horizontal steering shaft 18, thereby achieving horizontal steering. The axial steering knuckle 8 is connected to the head fixed frame 171 via the steering knuckle bearing 19. The horizontal steering knuckle 5 is connected to the tail fixed frame 172 at the tail of the machine via the tail steering shaft 25. The fixed frame is equipped with a brush shaft bearing 20 that rotatably connects to the brush shaft 12.

[0018] During the horizontal rotation process, the traveling wheel 9 will generate axial displacement. Therefore, in order to make the steering smoother, the traveling wheel 9 is set as an omnidirectional wheel. This converts the power generated by the traveling motor 6 into traveling displacement power while also making the steering smooth, thus solving the problem of front and rear misalignment of photovoltaic panels in photovoltaic power stations.

[0019] Furthermore, in order to solve the problem of gaps between photovoltaic panels in the photovoltaic power station, a 90-degree commutator 7 is installed between the traveling wheel 9 and the hanging wheel 10 for connection. The traveling motor 6 outputs power to the traveling wheel 9 and the hanging wheel 10 through the commutator 7. The traveling wheel 9 and the hanging wheel 10 can receive power at the same time, thereby solving the problem of jamming when the gap between each photovoltaic panel in the photovoltaic power station is 1-2cm.

[0020] The headstock roller 10 travels along the track, driving the horizontal steering knuckle 5 to turn around the horizontal steering shaft 18. The tailstock roller 10 travels along the track, driving the horizontal steering knuckle 5 to rotate around the tail steering shaft 25 located at the tail position 2, thus solving the problem of misalignment of photovoltaic panels in photovoltaic power plants in the existing technology.

[0021] The head unit 1 also includes a blower 15 mounted on a horizontal steering knuckle 5 and connected to the interior of the body 3; a brush 16 is spirally wound on the brush shaft 12; the head unit 1 and the tail unit 2 are respectively connected to the body 3 through their respective fixing brackets.

[0022] The exhaust fan 15 is designed to collect the dust that is stirred up during the cleaning process.

[0023] The center of the pulley 10 is perpendicular to the photovoltaic panel 22.

[0024] Commutator 7 is fixedly connected to walking wheel 9 via fixed sleeve 23; one end of brush 16 away from brush shaft 12 protrudes from body 3 and contacts photovoltaic panel of photovoltaic power station; The brush shaft 12 includes a female brush shaft 12.1 and a male brush shaft 12.2. A brush shaft fixing bracket 24 is provided between the female shaft 12.1 and the male shaft 12.2. The exhaust fan 15 is connected to the space where the brush shaft 12 is located.

[0025] Both the head mounting bracket 171 and the tail mounting bracket 172 have U-shaped slots at one end relative to the body 3, which are used to fix and adjust the distance between the brush and the photovoltaic panels of the photovoltaic power station for cleaning; the mounting brackets are provided with screws for connecting the body 3; both ends of the horizontal steering knuckle 5 are provided with sliding grooves for the walking motor 6 to engage; the body 3 is box-shaped.

[0026] The control box 4 contains a control module and a power module. The control module is electrically connected to the walking motor 6 and the brush motor 13, and the power module is electrically connected to the walking motor 6 and the brush motor 13.
