[0002] A large number of photovoltaic panels in a photovoltaic power station operation and maintenance system are usually arranged in rows and columns to ensure that the photovoltaic panels receive as much sunlight as possible and improve the overall power generation efficiency of the photovoltaic power station. Therefore, when using an intelligent cleaning robot to clean the photovoltaic panels, it is necessary to use a robot mobile platform to realize the position transfer of the cleaning robot between different photovoltaic panels; the robot mobile platform moves on the sides of several photovoltaic panels, and when successfully docked with a certain photovoltaic panel, the cleaning robot can move from the robot mobile platform to the photovoltaic panel. In the prior art, the docking between the robot mobile platform and the photovoltaic panel is mainly achieved by erecting multiple bridges between the robot mobile platform and the photovoltaic panel, and the heights of both ends of the bridge are adjustable; in this method, both ends of the bridge are respectively connected to the side of the robot mobile platform and the photovoltaic panel, and the connection strength is not high, making it difficult to ensure the stable movement of the cleaning robot on the bridge; moreover, the height adjustment of multiple bridges is relatively independent, and errors are likely to occur during adjustment, affecting the bearing effect when the cleaning robot passes through.

Although the preferred embodiments of the present specification are shown in the drawings, it should be understood that the present specification can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present specification more thorough and complete, and to fully convey the scope of the present specification to those skilled in the art.

[0024] The following will describe in detail a photovoltaic power station operation and maintenance device according to an embodiment of the present specification with reference to the accompanying drawings. Figure 1The structural schematic diagram of a photovoltaic power station operation and maintenance device according to an embodiment of this specification is shown. The photovoltaic power station operation and maintenance device of the embodiment of this specification includes a robot mobile platform 1, and the robot mobile platform 1 is used to carry a cleaning robot and transport it to the inclined photovoltaic panel 2; a pushing device and a docking device are arranged on the upper surface of the robot mobile platform 1, the pushing device pushes the docking device to dock with the side of the inclined photovoltaic panel 2, and after docking, the cleaning robot 4 can move between the robot mobile platform 1 and the inclined photovoltaic panel 2 through the docking device.

[0025] Among them, the distance between the robot mobile platform 1 and the inclined photovoltaic panel 2 is relatively short. When the heights of the robot mobile platform 1 and the inclined photovoltaic panel 2 are different, the docking structure between them will have a large slope, which is not conducive to the smooth passage of the cleaning robot 4; therefore, the surface height and inclination of the robot mobile platform 1 are adjustable. During use, first adjust the surface height and inclination of the robot mobile platform 1 to be consistent with the surface height and inclination of the inclined photovoltaic panel 2. When the inclined photovoltaic panel 2 needs to be cleaned, the robot mobile platform 1 moves to the side of the inclined photovoltaic panel 2, starts the pushing device to push the docking device to dock with the inclined photovoltaic panel 2. After docking, the cleaning robot 4 on the surface of the robot mobile platform 1 moves to the inclined photovoltaic panel 2 through the docking device to complete the cleaning work. The above docking process and the movement process of the cleaning robot 4 need to be remotely monitored through a camera device. The staff observes and records the docking effect through the camera device, and adjusts the movement of the cleaning robot 4 between the robot mobile platform 1 and the inclined photovoltaic panel 2 in time to reduce the failure rate and ensure the stable operation of the system. As Figure 3 shown, the camera device includes a first camera 51 and a second camera 52. The first camera 51 is used to observe the running state of the cleaning robot 4 and the running state of the pushing device. In addition to observing the running of the cleaning robot 4, the second camera 52 can also monitor the docking process of the docking device in real time to timely control the states of the cleaning robot 4 and the robot mobile platform 1; the number and installation positions of the first camera 51 and the second camera 52 are not limited to those shown in the figure. A part of the pushing device and the docking device is always located on the surface of the robot mobile platform 1, and the force bearing the cleaning robot 4 is more stable and has higher stability; the pushing device pushes the entire docking device to complete docking, without the need to separately adjust the various parts of the docking device, and the docking consistency is better, and the docking operation is simple and convenient. Moreover, in the non-docking state, the pushing device does not need to push the docking device outwards, reducing the space occupied on the side of the robot mobile platform 1 and being not easily interfered with other devices during movement or transportation.

[0026] Specifically, as Figure 1 shown, the pushing device includes an electric push frame 11 movably connected to the upper surface of the robot mobile platform 1 and a driving device; the electric push frame 11 is parallel to the side of the inclined photovoltaic panel 2, and the driving device drives the electric push frame 11 to move on the robot mobile platform 1 in a direction perpendicular to the side of the inclined photovoltaic panel 2; the docking device is a plurality of docking rods 12 perpendicular to the electric push frame 11, one end of the docking rod 12 is connected to the electric push frame 11, and the other end can be docked with the side of the inclined photovoltaic panel 2. Among them, the number of the docking rods 12 is not limited to that shown in the figure, and it is sufficient that the number is not less than the number of rows of the moving wheels at the bottom of the cleaning robot 4; when the robot mobile platform 1 is located on the side of the inclined photovoltaic panel 2, the docking rods 12 are aligned with the edge positions between the rows of photovoltaic panels of the inclined photovoltaic panel 2, facilitating the docking of the docking rods 12 with the inclined photovoltaic panel 2, and the moving wheels at the bottom of the cleaning robot 4 move to the edges between the rows of photovoltaic panels through the docking rods 12, reducing the wear on the surface of the photovoltaic panel. The driving mode of the electric push frame 11 is not limited to electric energy drive, and a push frame using hydraulic or other driving modes can also be used. When the driving device is a driving motor, the driving motor stops rotating to lock the position of the electric push frame 11 on the surface of the robot mobile platform 1.

[0027] In addition, in order to prevent the cleaning robot 4 moving onto the surface of the docking rod 12 from sliding out from one side of the electric push frame 11, the height of the side of the electric push frame 11 facing the cleaning robot 4 is higher than the height of the walking wheels of the cleaning robot 4, and a buffer device such as a rubber layer or an elastic layer can be provided on this side. A pressure sensor is also provided on the side of the cleaning robot 4 facing the electric push frame 11, and the pressure sensor is connected to the control box of the cleaning robot 4. When the cleaning robot 4 continues to move towards the electric push frame 11 after contacting the electric push frame 11, in order to prevent damage caused by excessive pressure between the cleaning robot 4 and the electric push frame 11, the pressure sensor detects the pressure between the cleaning robot 4 and the electric push frame 11, and when the pressure exceeds the threshold, the pressure sensor sends a warning signal to the control box to stop the operation of the cleaning robot 4.

[0028] The robot mobile platform 1 has a certain interval from the side of the inclined photovoltaic panel 2. In order to reduce the pushing distance of the electric push frame 11 during docking, reduce power consumption, and reduce the instability during the moving process, when the electric push frame 11 moves to the side of the upper surface of the robot mobile platform 1 away from the inclined photovoltaic panel 2, the docking rod 12 extends beyond the side of the upper surface of the robot mobile platform 1 close to the inclined photovoltaic panel 2. While reducing the docking moving distance, the lengthened docking rod 12 also facilitates aligning with the side of the inclined photovoltaic panel 2. Specifically, the length of the docking rod 12 should not be too long. When it is too long, it is easy to collide with the inclined photovoltaic panel 2 on the side and also easy to interfere with the center of gravity of the mobile platform 1, thus affecting the moving process. Therefore, when the docking rod 12 is not pushed, the length extending beyond the side of the robot mobile platform 1 is half of the interval between the side of the robot mobile platform 1 and the side of the inclined photovoltaic panel 2.

[0029] The embodiment of the present specification also provides a photovoltaic power station operation and maintenance system. The photovoltaic power station operation and maintenance system provided by the embodiment of the present specification includes the above-mentioned robot mobile platform 1, an inclined photovoltaic panel 2 located on the side of the robot mobile platform 1, a platform moving track 3 for carrying the robot mobile platform 1, and a cleaning robot 4 that can move on the robot mobile platform 1 and the inclined photovoltaic panel 2. Among them, as Figure 2 shown, there are several columns of the inclined photovoltaic panels 2, and several columns of the inclined photovoltaic panels 2 are arranged in parallel. The platform moving track 3 is located on one side of the inclined photovoltaic panel 2. The robot mobile platform 1 can move to the sides of different inclined photovoltaic panels 2 through the platform moving track 3 and complete docking with different photovoltaic inclined panels 2. Specifically, the moving structure between the robot mobile platform 1 and the platform moving track 3 includes supporting wheels, side supporting wheel groups, and lower hanging wheel groups. The supporting wheels, the side supporting wheel groups, and the lower hanging wheel groups are all arranged at the bottom of the robot mobile platform 1 and are in contact with and roll on the upper surface, side surface, and bottom surface of the platform moving track 3 respectively. The distances between the side supporting wheel groups and the lower hanging wheel groups and the platform moving track 3 are adjustable, so that the moving structure at the bottom of the robot mobile platform 1 is in close contact with the platform moving track 3, ensuring the stability of the robot mobile platform 1 during the moving process.

[0030] In order to adjust the height and inclination of the surface of the robot mobile platform 1 to be consistent with the height and inclination of the surface of the inclined photovoltaic panel 2. The bottom of the platform moving track 3 is provided with a lifting and adjusting device, as Figure 1As shown, a lifting bracket 32 is provided at the bottom of the platform moving track 3 near the side of the inclined photovoltaic panel 2. By adjusting the height and height difference of several lifting brackets 32, the height and inclination of this section of the platform moving track 3 can be adjusted, and then the height and inclination of the upper robot moving platform 1 can be adjusted, facilitating the docking between the robot moving platform 1 and the inclined photovoltaic panel 2. A clamping member 21 matching the end of the docking rod 12 is provided on the side of the inclined photovoltaic panel 2. During docking, the clamping member 21 locks the end of the docking rod 12, increasing the stability after docking. A position sensor is provided on one side of the robot moving platform 1 close to the inclined photovoltaic panel 2 for detecting the adjustment effect of the lifting bracket 32. When adjusting the lifting bracket 32, the position sensor continuously detects the height and inclination angle between the upper surface of the robot moving platform 1 and the inclined photovoltaic panel 2. When the height and inclination angle between the upper surface of the robot moving platform 1 and the inclined photovoltaic panel 2 are consistent, the position sensor emits an alignment signal, and at this time, the adjustment of the lifting bracket 32 is stopped. An elevating adjustment device can also be provided inside the robot moving platform 1 to adjust the height and inclination of the upper surface of the robot moving platform 1.

[0031] In addition, a power supply photovoltaic panel 31 is further provided above the platform moving track 3 for supplying power to the pushing device, the cleaning robot 4, and the robot moving platform 1, realizing self-power supply for the entire system using solar energy and reducing power consumption. A cleaning device is also provided on the bottom surface of the robot moving platform 1 to clean the power supply photovoltaic panel 31 when moving on the platform moving track 3, ensuring the light energy conversion efficiency of the power supply photovoltaic panel 31.
