[0002] With the country's increasing emphasis on alternative energy sources and policy support, solar photovoltaics, as a key clean energy source, is experiencing unprecedented growth in both speed and scale. The rapid expansion of photovoltaic power plants has also created challenges in panel cleaning. Addressing the efficient cleaning of photovoltaic power plant components has become a key component in improving energy efficiency and reducing operational costs. Traditional cleaning methods, currently primarily performed by manual labor, are inefficient, costly, and consume significant amounts of water. These methods are also safer and require less accidents when performed in locations where access to heights is inconvenient. In recent years, automated photovoltaic panel cleaning robots have emerged as a solution designed to automate this process. However, the diverse and irregular installation locations of photovoltaic panels, subject to construction deviations and terrain variations, result in varying installation angles and heights, posing a challenge to the widespread deployment of universal cleaning robots. Currently available cleaning robots are mostly designed for specific photovoltaic arrays and lack the flexibility to adapt to a wide range of installation configurations, limiting their application. To address this challenge, it is crucial to explore and develop new robotic technologies that can intelligently adapt to diverse installation conditions, offering high flexibility and efficient cleaning capabilities.

[0023] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] Combined with attachment Figure 1-5 A mobile photovoltaic cleaning robot is suitable for photovoltaic power stations with small photovoltaic panel angles and has good compatibility with terrain and power station environments. The main body of the photovoltaic cleaning robot consists of three parts: a body assembly 100, a cleaning roller brush assembly 200 installed on both sides of the body assembly 100, and a water slip ring assembly 300 installed on the body assembly 100; the body assembly 100 is responsible for the walking and overall control of the cleaning robot, the cleaning roller brush assembly 200 is responsible for cleaning the photovoltaic panel surface, and the water slip ring assembly 300 is the waterway part used to ensure that the waterway can be unobstructed under various circumstances.

[0026] The main assembly 200 includes a box frame 101 as a basic frame, and an active synchronous wheel 111 and a driven synchronous wheel 110 are respectively provided on both sides of the box frame 101. A crawler 102 is provided between the active synchronous wheel 111 and the driven synchronous wheel 110. The active synchronous wheel 111 is used to drive the crawler 102 to rotate, and the driven synchronous wheel 110 is used to support the crawler 102 so that the crawler meets the rotation conditions. The main assembly 200 realizes the movement of the cleaning robot by the crawler 102 provided on both sides of the box frame 101. The box located inside the active synchronous wheel 111 A motor for driving an active synchronous wheel 111 is provided in the frame 101. The active synchronous wheels 111 on both sides are driven separately by different mobile motors. When the tracks 102 on both sides rotate synchronously, the cleaning robot moves in a certain direction. When there is a speed difference between the tracks 102 on both sides, the cleaning robot can turn and rotate toward the side of the slower track, thereby completing the change of the moving direction of the cleaning robot. A control board is provided in the box frame 101 for separately controlling the mobile motors that drive the active synchronous wheels 111 on both sides.

[0027] The box frame 101 is preferably made of aluminum alloy plates welded in one piece, which has the characteristics of good strength, light weight, and good waterproof sealing. The track 102 is provided with special patterns to increase friction, which can effectively avoid slipping.

[0028] Auxiliary idler wheels 112 are also provided on both sides of the box frame 101 between the active synchronous wheel 111 and the driven synchronous wheel 110. The auxiliary idler wheels 33 are rotatably arranged on both sides of the box frame 101 that is biased towards the lower side. The auxiliary idler wheels 112 are in contact with the lower part of the track 102. The auxiliary idler wheels 112 support the track 102 on the lower side, so that when the cleaning robot is in use, the track 112 can maintain contact with the surface of the photovoltaic panel to provide sufficient friction, and when the robot moves to a new photovoltaic panel, the auxiliary idler wheels can also play an auxiliary supporting role to enable the cleaning robot to cross a certain gap.

[0029] The use of tracks as a walking mechanism allows the PV cleaning robot to easily navigate small obstacles and irregularities on the PV panel surface, reducing the possibility of being unable to clean the panels due to site restrictions. The wide contact area of ​​the tracks disperses the robot's pressure on the ground, reducing the risk of damage to the PV panel glass surface. Even on slippery glass surfaces, the track structure provides sufficient friction to maintain stability during operation and prevent slipping.

[0030] The driven synchronous wheel 110 is provided with a tensioning mechanism 109, which is used to adjust the position of the driven synchronous wheel 110. By adjusting the position of the driven synchronous wheel 110, the tightness of the crawler 102 is adjusted, so that the crawler 102 maintains the most appropriate contact area with the photovoltaic panel, and obtains the friction force that is most conducive to the movement of the cleaning robot. The tensioning mechanism 109 is composed of a fixing flange fixed to one side of the box frame 101 and a bearing sleeved on the driven synchronous wheel 110, and a fixing rod with one end inserted into the fixing flange and the other end fixed on the bearing. By adjusting the position of the fixing rod inserted into the fixing flange, the position of the driven synchronous wheel 110 is adjusted. The fixing rod and the fixing flange adopt an adjustable tightness fit, that is, when loosened, the position of the fixing rod in the fixing flange can be freely adjusted. When fixed, the fixing flange will lock the fixing rod so that it cannot move, thereby fixing the position of the driven synchronous wheel 110. The fixing flange can be tightened with a bolt to tighten the fixing rod, or the threaded screw can be abutted against the fixing rod.

[0031] Roller brush connectors 103 are provided on both sides of the box frame 101. The roller brush connectors 103 are used to install and fix the cleaning roller brush assembly 200. The roller brush connectors 103 adopt a flexible quick-release structure, preferably a latch design, that is, the cleaning roller brush assembly 200 is detachably inserted on the roller brush connector 103. The roller brush connector 103 consists of a protruding connector and is provided with a circular hole and a notch on the connector. The matching connector of the cleaning roller brush assembly 200 consists of a protruding insert and is provided with a matching hole aligned with the circular hole and a protrusion for inserting into the notch on the insert. After aligning the circular hole and the matching hole, the latch is inserted into the circular hole and the matching hole, thereby fixing the cleaning roller brush assembly 200 on the roller brush connector 103 of the box frame 101. The latch design can quickly separate the roller brush from the vehicle body for easy transportation. The flexible roller brush design can ensure that the roller brush better fits the photovoltaic panel surface when the photovoltaic array is not neat.

[0032] The box frame 101 is also provided with a removable battery 104, a power switch 107, and an antenna 105. The removable battery 104 can continuously provide power to the cleaning robot by replacing the battery, thereby extending the use time of the cleaning robot. The power switch 107 can turn off and on the cleaning robot. The antenna 105 can greatly extend the control distance of the cleaning robot, making it convenient for workers to control the cleaning robot remotely. The battery 104 is preferably a lithium battery to ensure that the machine has sufficient power supply and is lighter in weight. A slot for accommodating the battery 104 is provided in the box frame 101, which is opened by a flip-up cover. The cover can protect the battery.

[0033] A handle 108 may also be provided on the box frame 101 to facilitate workers in moving, collecting, and transporting the cleaning robot. The box frame 101 is covered with a protective shell to protect internal components.

[0034] During use, the box frame 101 provides support for the entire vehicle assembly 200 and connects the various components. The track 102 features a special pattern to effectively prevent slipping. It utilizes a synchronous pulley structure, with the active synchronous pulley 111 providing power. The driven synchronous pulley 110 cooperates with the tensioning mechanism 109 to tighten the track. The auxiliary idler pulley assembly 112 provides flexible support in the middle of the track, increasing the track's friction and terrain adaptability. The roller brush connector 103 connects the roller brush to the vehicle body. The battery 104 powers the entire system. The antenna 105 amplifies the control module's signal, increasing the remote control range. The power switch 107 controls the entire machine's power supply.

[0035] The cleaning roller brush assembly 200 includes a frame cover 205 as an installation base. The frame cover 205 provides support and dust protection for the cleaning roller brush assembly 200. A roller brush 201 is rotated inside the frame cover 205. The roller brush 201 is preferably made of nylon fiber material. The roller brush made of nylon fiber material has the advantages of wear resistance, aging resistance and gentleness to the surface of the photovoltaic panel. It can effectively remove dirt without damaging the glass surface. At the same time, the roller brush made of flexible material can ensure that the roller brush can better fit the photovoltaic panel surface when the photovoltaic array is uneven, thereby ensuring the cleaning effect. The surface of the photovoltaic panel is cleaned by the high-speed rotation of the roller brush 201. A drive motor 201 is provided on either side of the roller brush 201 in the frame cover 205. The drive motor 202 is responsible for providing power to the roller brush 201 to ensure the cleaning effect.

[0036] A spray pipe 204 is provided on the side of the frame cover 205 away from the vehicle body assembly 100. The spray pipe 204 is responsible for spraying high-pressure water mist to directly wash away some dust on the surface of the photovoltaic panel and wet the photovoltaic panel to facilitate the roller brush to clean stubborn stains.

[0037] Scraping strips 203 are provided on both sides of the frame cover 205 or at least on the side close to the vehicle body assembly 100. The main function of the scraping strips 203 is to scrape away the residual dirty water on the photovoltaic panel to ensure that the photovoltaic panel does not leave sewage watermarks.

[0038] The frame cover 205 provides support and protection for the entire cleaning roller brush assembly 200. By adopting the design of the front and rear double roller brushes, the cleaning effect and efficiency are greatly improved.

[0039] The water slip ring assembly 300 consists of a bracket 304 as a carrier, and a rotary joint 304 installed on the bracket 304. The rotary joint 304 is connected to an aluminum tube 302, and the end of the aluminum tube 302 is connected to a water pipe joint 301. The water pipe joint 301 is used to connect an external water supply pipe to connect the waterway. The rotary joint 303 is used to ensure that the waterway can be unobstructed at all rotation angles without tangling.

[0040] A roller brush joint 106 is also provided on the vehicle body assembly 200, which is used to connect to the spray pipe 204 of the cleaning roller brush assembly 200. The water slip ring assembly 300 is connected to the cleaning liquid through the adapter 304 and the aluminum tube 302 and connected to the spray pipe 204 to facilitate the use of the spray pipe 204.
