Description

Technical Field

[0001] This utility model relates to the fields of intelligent robots and photovoltaic technology, and in particular to a photovoltaic panel cleaning robot. Background Technology

[0002] As the global energy structure accelerates its shift towards renewable energy, the capacity of individual photovoltaic (PV) power plants has rapidly increased from megawatts to hundreds of megawatts. This has amplified the impact of accumulated dust, bird droppings, industrial debris, and salt spray on the surface of PV panels on power generation efficiency. In typical high-irradiance, high-dust areas, dust accumulation on PV panels can lead to a power degradation of over 15% in just two weeks. If mud belts form during the rainy season, localized hot spot effects can cause annual power generation losses of up to 25% or more, and accelerate backsheet yellowing, cell microcracks, and shorten module lifespan by 3–5 years.

[0003] Traditional manual water washing or vehicle-mounted spraying methods suffer from drawbacks such as short cleaning windows, high labor costs, easy trampling of panels, and insufficient uniformity. While fixed spraying systems can partially replace manual labor, problems such as pipe freezing and cracking in winter, nozzle clogging, blind spots in rinsing, and chemical cleaning agent residue remain unresolved. To address the shortcomings of traditional photovoltaic panel cleaning methods, photovoltaic panel cleaning robots have emerged.

[0004] In recent years, photovoltaic panel cleaning robots have undergone iterations from "rail-guided to semi-suspended to fully autonomous trackless": early rail-guided robots required pre-set racks along the module frame, resulting in high installation costs and stringent requirements for module layout consistency; semi-suspended robots operated across rows using steel cables or aluminum alloy tracks, eliminating the need for single-row rails, but were limited by large-span deflection, making them only suitable for regular matrix power plants and unsuitable for complex terrains such as mountainous areas and solar-aquaculture hybrid systems. Currently, the mainstream solution is the fully autonomous trackless robot, which can walk directly on inclined panels, but it still suffers from technical problems such as poor waterproofing, inconvenient energy supply, and slippage of the drive wheels, leading to robot jamming or even falls.

[0005] The above background information is provided only to assist in understanding the concept and technical solution of this utility model. It does not necessarily belong to the prior art of this application, nor does it necessarily provide technical guidance. In the absence of clear evidence that the above information was disclosed before the filing date of this application, the above background information should not be used to evaluate the novelty and inventiveness of this application.

[0051] In one embodiment of this utility model, a photovoltaic panel cleaning robot is provided, see [link to relevant documentation]. Figures 1 to 8 The photovoltaic panel cleaning robot includes a cleaning component 1, a sensor component 2, a housing 3, a water supply component 4, a power supply component 5, a walking drive component 6, an operation component 7, and an electrical component 8.

The power assembly 5 is disposed within the receiving cavity and connected to the upper housing 31. One end of the battery compartment cover 311 is hinged to the upper housing, and the other end is connected to the upper housing 31 via a snap-fit ​​structure. A sealing ring is also provided around the inner periphery of the battery compartment cover. A battery compartment 312 is disposed below the battery compartment cover 311, and the power assembly 5 is disposed within the battery compartment 312.

The battery compartment also includes a USB mounting bracket and a power connector, which are fixed to the cavity by screws.

[0055] It also includes an electrical component 8, which is disposed within the receiving cavity and connected to the upper housing 31. In this embodiment, the lower housing 32 is only connected to the upper housing 31 and is not connected to other components within the receiving cavity. Furthermore, a gap is provided between the lower housing 32 and any component within the receiving cavity. This invention avoids the risk of water leakage at the seams in a separate upper and lower housing design, and solves the problem of waterproofing the top of the entire machine, by installing all electrical components / parts inside the cleaning robot housing onto the upper housing.

[0056] like Figure 3As shown, the electrical component 8 includes a main control board 81, a power distribution board 82, a driver 83, an antenna module 33, and a wiring harness. The main control board 81, driver 83, and wiring harness are all connected to the upper housing 31. The housing 3 also includes several connectors 35, which are disposed within the receiving cavity and connected to the inner wall of the upper housing 31. In one specific embodiment, there are four transverse connectors 35 inside the upper housing, each connector 35 being connected to the left and right sidewalls of the housing by screws. The main control board 81, driver 83, and wiring harness are respectively connected to the connectors 35 by fasteners. Specifically, the main control board 81 and power distribution board 82 are fixed to two transverse connectors 35 by screws and are located below the front camera. Two drivers 83 are respectively fixed to two other transverse connectors 35 by screws and are located below the water supply component 4. The wiring harness is distributed on both sides inside the upper housing and is fixed to the transverse connectors 35 by wire clips.

[0057] like Figure 1 As shown, a signal amplification module 313 is disposed on the upper part of the upper housing 31. The signal amplification module 313 can be encapsulated in a plastic housing, and the housing of the signal amplification module 313 is fixed to the upper housing 1. The signal amplification module 313 is electrically connected to an antenna module 33 inside the housing 3 via a cable. A through hole is provided on the upper housing at a position corresponding to the signal amplification module 313 for the cable to pass through. Optionally, the antenna module 33 is disposed on the housing of the driver 83.

[0058] The conventional design of cleaning robots involves mounting some components on an upper shell and others on a lower shell, which are then joined together. Before joining, numerous wires need to be connected in the air between the two parts, requiring sufficient space for connections. After joining, these wires are uncontrolled and become tangled and unfixed internally, leading to short circuits or unstable signal transmission. This embodiment addresses this by mounting all internal electrical components on the upper shell, ensuring that the positions of the components and wires are relatively fixed. This solves assembly difficulties and product stability issues. Furthermore, during machine maintenance, the lower shell can be easily disassembled to inspect all internal components and wiring connections, facilitating installation, disassembly, inspection, and maintenance.

[0059] In this embodiment, the cleaning component 1 is configured to clean the target object. For example...

The height adjustment mechanism 11 is configured to adjust the height of the roller brush 15 and the roller brush housing 16. This application does not limit the specific structure of the height adjustment mechanism 11; for example, the height adjustment mechanism 11 can specifically employ a screw mechanism, a rotating mechanism, or a combination of both, or other height adjustment mechanisms.

[0060] The motor 12 is used to drive the roller brush 15 to rotate in order to clean the target cleaning surface. Specifically, the output shaft of the motor 12 is connected to the corresponding rotating shaft of the roller brush 15.
