Abstract
Description

[0002] With the increasing number of photovoltaic power stations, the impact of panel cleaning on power generation efficiency has become increasingly significant. Traditional manual cleaning methods are often limited by the photovoltaic installation environment, making cleaning difficult. Therefore, the demand for photovoltaic cleaning robots has gradually become prominent.
[0003] At present, domestic photovoltaic cleaning robots mainly include: single-row cleaning robots, multi-row cleaning robots and mobile cleaning robots. The current market attaches great importance to mobile cleaning robots. Because of their generally small size and easy to carry, they are listed as the first choice by most power stations. However, the cleaning efficiency of mobile robots is proportional to their size and movement speed, which is generally lower than that of single-row cleaning robots. In addition, they are greatly affected by the terrain, mainly based on the latitude of the photovoltaic panel installation site. In order to make the photovoltaic panels receive higher light radiation intensity, the angles of the photovoltaic panels vary greatly. The mobile photovoltaic cleaning robots mainly rely on friction walking, which determines that without the assistance of external devices, the acceptable angles are limited. At present, they are basically 30 degrees for dry cleaning and 25 degrees for wet cleaning. Utility Model Content

[0025] 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.
[0026] Example 1
[0027] Combined with attachment Figure 1-4, a photovoltaic panel cleaning robot. Since the photovoltaic panels are all arranged at an angle, the cleaning robot of this application is located at one end at the top of the photovoltaic panel and the other end at the bottom of the photovoltaic panel, and cleans the photovoltaic panel by moving horizontally. It includes a main frame 10. The theme frame 10 is the installation frame of the cleaning robot. The components are all on the main frame 10. The main frame 10 is a long rectangular frame. The main frame 10 is rotated to be provided with a cleaning roller brush 11. The length of the cleaning roller brush 11 is the same as the length of the photovoltaic panel to be cleaned. The cleaning roller brush 11 can cover the long surface of the photovoltaic panel. The surface of the photovoltaic panel can be cleaned once through one complete movement. There is no need to clean the photovoltaic panel in sections one by one, which is efficient and convenient.
[0028] An upper drive assembly 20 and a lower drive assembly 40 are respectively provided on both sides of the main frame 11. The upper drive assembly 20 and the lower drive assembly 40 are used to drive the cleaning robot to move and at the same time provide power for the cleaning roller brush 11. The upper drive assembly 20 is located at one end of the main frame 10, and the lower drive assembly 40 is located at the other end of the main frame 10. When the cleaning robot is located on the photovoltaic panel, the upper drive assembly 20 is located on the upper side of the photovoltaic panel, and the lower drive assembly 20 is located on the lower side of the photovoltaic panel. The upper drive assembly 20 and the lower drive assembly 40 are respectively engaged at both ends of the photovoltaic panel, so that the cleaning robot can move stably on the photovoltaic panel, thereby cleaning the photovoltaic panel.
[0029] The upper driving assembly 20 includes an upper supporting frame 21 installed at the end of the main frame 10. The upper supporting frame 21 passes through the main frame 10 horizontally and extends symmetrically on both sides. The upper supporting frame 21 is provided with side plates and a bottom plate, which are respectively used to install rotating wheels of different directions and angles. The side plates of the upper supporting frame 21 are respectively provided with an upper driving wheel 22 and an upper driven wheel 23. The upper driving wheel 22 is a rotating wheel with a power structure that can rotate by itself. The upper driving wheel 22 is preferably symmetrically arranged on the inner side of the upper supporting frame 21 in the main frame 10, and an upper driving motor 24 for driving the upper driving wheel 22 is provided on the outer side of the upper supporting frame 21. The upper driving motor 24 drives the upper driving wheel 22 to rotate.
[0030] Upper driven wheels 23 are rotatably provided on both sides of the upper support frame 21 located on the outside of the active frame 10. The upper driven wheels 23 are symmetrically arranged at both ends of the upper support frame 21. The upper driven wheels 23 extend to both sides of the main frame 10, so that when the cleaning robot moves on the photovoltaic panel, the distance between the upper driven wheels 23 on both sides is wider, so that the movement of the cleaning robot can be made more stable, and the cleaning robot will not shake when moving.
[0031] The upper driving wheel 22 and the upper driven wheel 23 rotate on the upper side of the surface of the photovoltaic cleaning panel frame on which the photovoltaic cleaning panel is installed. The upper driving wheel 22 and the upper driven wheel 23 are provided with pulleys on their respective rotating shafts, so that the first transmission belt 27 is connected between the pulleys of the upper driving wheel 22 and the upper driven wheel 23, thereby causing the upper driving wheel 22 to drive the upper driven wheel 23 to rotate synchronously.
[0032] The upper support frame 21 is located on the bottom surface inside the main frame 10 and is rotatably provided with an upper driven guide wheel 25. The upper driven guide wheel 25 is preferably arranged corresponding to the upper driving wheel 22. The upper support frame 21 is located on the bottom surfaces on both sides outside the main frame 10 and is provided with upper active guide wheels 26 corresponding to the upper driven wheels 23. The upper active guide wheels 26 rotate on the upper side surface of the photovoltaic cleaning panel frame on which the photovoltaic cleaning panel is installed.
[0033] The upper driving wheel 22, the upper driven wheel 23, the upper driven guide wheel 25, and the upper active guide wheel 26 are respectively arranged vertically. At the same time, the upper driven wheel 23 drives the upper active guide wheel 26 to rotate through the reversing transmission component. The reversing transmission component is preferably a coupling or a bevel gear, helical gear, or other component that can synchronously transmit vertically.
[0034] The upper driving assembly 20 drives the cleaning robot to move by rotating the upper driving wheel 22 , the upper driven wheel 23 , the upper driven guide wheel 25 , and the upper active guide wheel 26 .
[0035] The lower driving assembly 40 includes a lower supporting frame 41 installed at the other end of the main frame 10. The lower supporting frame 41 is provided with a lower driving wheel 42 and a lower driven wheel 43 which are the same as those of the upper supporting frame 21. The lower driving wheel 42 also drives the lower driven wheel 43 to rotate through a second transmission belt 44. The upper driving wheel 22 is also arranged on the inner side of the lower supporting plate 41. The outer side of the lower supporting plate 41 is also provided with a lower driving motor 46 corresponding to the lower driving wheel 42. The lower driving motor 46 is synchronously driven with the upper driving motor 22, so that the cleaning robot will not tilt due to different rotation speeds on both sides. The bottom of the lower supporting frame 41 is also provided with a lower driving wheel 42 which is opposite to the lower driving wheel 42. The corresponding lower driven guide wheel 45 is arranged in the same way as the upper driven guide wheel 25. The lower driving wheel 42 and the lower driven wheel 43 are arranged on the lower side of the surface of the photovoltaic cleaning board frame on which the photovoltaic cleaning board is installed and rotate. The lower driven guide wheel 45 rotates on the lower side surface of the photovoltaic cleaning board frame on which the photovoltaic cleaning board is installed. At the same time, the upper active guide wheel 26 can cooperate with the lower driven guide wheel 45 to provide the cleaning robot with an anti-stuck and deviation correction function. The upper driven guide wheel 25, the upper active guide wheel 26, and the lower driven guide wheel 45 can also enable the cleaning robot to adapt to photovoltaic panels with a larger inclination angle, effectively improving the cleaning robot's adaptability to the environment.
[0036] The cleaning robot is able to move on the surface of the photovoltaic panel through the upper driving wheel 22, the upper driven wheel 23 and the lower driving wheel 42, the lower driven wheel 43, thereby completing the cleaning function; the upper driven guide wheel 25, the upper active guide wheel 26 and the lower driven guide wheel 45 are clamped on the upper and lower sides of the photovoltaic panel. At this time, the upper driven guide wheel 25, the upper active guide wheel 26 and the lower driven guide wheel 45 can cooperate with the upper side sides of the photovoltaic panel to keep the cleaning robot at the correct height and angle on the photovoltaic panel without deviation.
[0037] A cleaning drive motor 47 can be set at the position corresponding to the cleaning roller brush 11 on the upper support frame 21 and the lower support frame 41. The cleaning drive motor provides power for the cleaning roller brush 11. The cleaning drive motor 47 drives the cleaning roller brush 11 to rotate at high speed, so that the cleaning robot has higher cleaning efficiency.
[0038] Water pipes 50 are provided on both sides of the cleaning roller brush 11 in the main frame 10. Several water spray outlets 51 are provided at intervals on the water pipes 50 in the main frame 10. The water pipes 50 can be set on the main frame 10 on both sides of the cleaning roller brush 11. The two pipes are externally connected to the cleaning liquid supply pipe, so that cleaning liquid continuously flows into the water pipes 50, and the cleaning liquid 51 is sprayed on both sides of the cleaning roller brush 11 through the water spray outlets 51 on the water pipes 50. The two water pipes 50 are respectively connected to external pipes, so that cleaning liquids with different functions are sprayed out from their respective water spray outlets 51. For example, the water pipe 50 on one side is a cleaning liquid for cleaning, and the water pipe 50 on the other side is a protective liquid for protecting the surface of the photovoltaic panel.
[0039] Either or both of the upper drive assembly 20 and the lower drive assembly 40 can be provided with a ranging photoelectric sensor 52 located on both sides of the upper driven guide wheel 25 or the lower driven guide wheel 45 on the bottom surface of the upper support frame 21 or the lower support frame 41. The ranging photoelectric sensor 52 can detect whether the distance between the left and right sides of the cleaning robot is consistent with the distance between the sides of the photovoltaic panel, that is, whether the cleaning robot is going astray, or the cleaning robot has a tendency to go astray. Then, the program control is used to automatically correct the travel speed and make the robot return to the straight position.
[0040] Edge detection photoelectric sensors 55 are symmetrically provided on both sides of the upper and lower ends of the main frame 10. The edge detection photoelectric sensors 55 are extended by connecting rods 59 and installed on the upper support frame 21 or the lower support frame 41 fixedly connected to the main frame 10. When the cleaning robot moves to both ends of the photovoltaic panel, it transmits signals in time to prevent the robot from falling off the photovoltaic panel, thereby detecting whether the robot is close to the edge of the photovoltaic panel, stopping the machine in time, or cleaning back and forth.
[0041] One of the upper support frame 21 or the lower support frame 41 is provided with a pluggable battery 53 for powering the lower drive motor 46, the upper drive motor 22 and the cleaning drive motor 47. The pluggable battery 53 allows for quick replacement, which facilitates the continuous operation of the cleaning robot. One of the upper support frame 21 or the lower support frame 41 is also provided with an electric control module 54. The electric control module 54 is electrically connected to the lower drive motor 46, the upper drive motor 22, the cleaning drive motor 47, the ranging photoelectric sensor 52, and the photoelectric sensor 55. The electric control module 54 is the control system of the cleaning robot, preferably a PCB control panel and components such as a single-chip microcomputer, including the start and stop of the cleaning robot, the roller brush switch, the sensor feedback, etc., and is preferably fixed to the higher part of the shell to prevent water accumulation in the lower drive assembly 40 from affecting the use of the electric control.
[0042] The main frame 10 is wrapped with a shell to provide protection for the main frame 10 and the components in the upper support frame 21 and the lower support frame 41, preventing water or dust from directly contacting the motor or other precision parts, and curbing the hidden dangers of short circuit or failure.
[0043] In other embodiments, the lower drive assembly 40 may not be provided with a power source, and the upper drive assembly 20 may directly drive the entire cleaning robot to move, and the lower drive assembly 40 only performs the function of preventing deflection and jamming.
[0044] Several intermediate support frames 60 can also be set locally on the main frame 10, and unpowered wheels 61 are set on the intermediate support frames 60. The unpowered wheels 61 only play a supporting role, ensuring that the main frame 10 remains parallel to the photovoltaic panel with the assistance of the unpowered wheels 61, ensuring structural stability, and at the same time supporting the cleaning roller brush 11 to ensure that the rotating axis of the roller brush is parallel to the photovoltaic panel.
[0045] The upper driving wheel 22, the upper driven wheel 23 and the lower driving wheel 42, the lower driven wheel 43 can all be selected to avoid wheels with concave and convex structures, thereby increasing friction, preventing slipping during rotation, and allowing the cleaning robot to move stably.
[0046] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
