Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, and more specifically, to a cleaning robot for cleaning photovoltaic panels. Background Technology

[0002] Against the backdrop of the global push for clean energy development, photovoltaic (PV) power generation is playing an increasingly important role in the energy sector due to its significant advantages such as being pollution-free and sustainable. Both large-scale centralized PV power plants and widely distributed distributed PV power plants are experiencing rapid growth in installed capacity. However, as the core component of a PV power generation system, the performance of PV panels is highly susceptible to interference from external environmental factors. In practical applications, many PV power plants are located far from populated areas with harsh environmental conditions. Long-term exposure to the natural environment inevitably leads to the accumulation of large amounts of dust, oil, bird droppings, and other pollutants on the surface of the PV panels. This not only severely affects the power generation efficiency of the entire PV system, significantly reducing revenue, but also increases power generation costs, greatly harming the economic benefits of PV power plants.

[0003] Currently, most photovoltaic panel cleaning is done manually. However, manual cleaning has many drawbacks: First, labor costs remain high. With the continuous rise in labor market prices, cleaning operations for large-scale photovoltaic power plants require huge manpower costs, significantly increasing the operational burden. Second, cleaning efficiency is low. Manual operation is limited by physical strength and work pace, making it difficult to achieve rapid batch cleaning of photovoltaic panels, especially as the scale of power plants expands. Third, the safety risks are extremely high. Operators need to frequently climb to high places where photovoltaic panels are installed. In complex outdoor environments, they are prone to slipping, falling, and other safety accidents, posing a serious threat to their lives. Utility Model Content

This further improves the cleaning effect and protects the photovoltaic panel. On the other hand, the filter plate is slidably connected to the fixed shell through the guide block, and can be quickly locked and unlocked with the help of the plug rod, spring, and lever. When the filter plate becomes clogged due to long-term use, the operator only needs to move the lever to release the plug rod from the pull ring, and easily pull out the filter plate for cleaning or replacement. The operation is simple and quick, effectively reducing the difficulty and time cost of equipment maintenance and ensuring the continuous and efficient operation of the drying system.

Several through holes are opened on the outer surface of the hollow shaft 8. An inlet pipe 9 is movably connected to the inner front end of the hollow shaft 8. A liquid pump 37 is installed at the end of the inlet pipe 9 away from the hollow shaft 8. A hose can be installed on the liquid pump 37. A cleaning roller 10 is fixedly connected to the outer surface of the hollow shaft 8. A brush is provided on the outer surface of the cleaning roller 10. A water outlet hole corresponding to the through hole on the hollow shaft 8 is opened on the cleaning roller 10. In the cleaning mechanism, the long shaft 3 provides a mounting carrier for the drive wheel 5, the first gear 4, and the second gear 6. Its movable connection with the housing 1 ensures stable rotation. The first gear 4 is used to receive the power of the drive mechanism to drive the long shaft 3 to rotate. The drive wheel 5 can drive the robot to move by rotating. The second gear 6 meshes with the third gear 7 to transmit power to the hollow shaft 8. The hollow shaft 8 delivers cleaning liquid to the cleaning roller 10 through the through hole on its outer surface. Its movable connection with the arc-shaped housing 2 ensures smooth rotation. The liquid inlet pipe 9 delivers cleaning liquid to the hollow shaft 8. The liquid pump 37 provides power for the delivery of cleaning liquid.

[0015] The drive mechanism includes: Vertical plate 11, the top of vertical plate 11 is fixedly connected to the inside of the housing 1, and a motor 12 is fixedly installed on the outer surface of vertical plate 11. A rotating shaft 13 is fixedly sleeved on the output end of motor 12. The fourth gear 14 is fixedly sleeved with the outer surface of the rotating shaft 13, and the outer surface of the fourth gear 14 is meshed with the outer surface of the first gear 4. In the drive mechanism, the vertical plate 11 provides fixed support for the motor 12, ensuring the stable operation of the motor 12. The motor 12 serves as a power source, and its output shaft 13 can drive the fourth gear 14 to rotate. The fourth gear 14, through meshing with the first gear 4, transmits the power of the motor 12 to the long shaft 3, thereby driving the long shaft 3 and related components to operate, providing a power basis for the robot's movement and cleaning.

[0016] A connecting block 15 is fixedly installed on the outer surface of the housing 1. A protective shell 16 is fixedly installed on the end of the connecting block 15 away from the housing 1. The interior of the protective shell 16 is movably connected to the outer surfaces of the long shaft 3 and the hollow shaft 8. The second gear 6 and the third gear 7 are both located inside the protective shell 16. The connecting block 15 is used to connect the housing 1 and the protective shell 16, so that the protective shell 16 can be stably installed in a suitable position. The protective shell 16, through its movable connection with the long shaft 3 and the hollow shaft 8, encloses the transmission components such as the second gear 6 and the third gear 7, which can effectively block the entry of external dust and impurities, avoid contamination or damage to the transmission components, and thus ensure the stable operation of the internal transmission structure.

[0017] Among them, a fixed plate 17 is fixedly installed on the outer surface of the arc-shaped shell 2, a short shaft 18 is fixedly sleeved inside the fixed plate 17, a driven wheel 19 is movably sleeved at the end of the short shaft 18 away from the fixed plate 17, a slide rail 20 is rolledly connected to the outer surface of the driven wheel 19, and the interior of the slide rail 20 is rolledly connected to the outer surface of the drive wheel 5. The fixed plate 17 provides mounting support for the short shaft 18. The movable connection between the short shaft 18 and the driven wheel 19 allows the driven wheel 19 to rotate flexibly. The driven wheel 19 cooperates with the drive wheel 5 to roll along the slide rail 20, which can enhance the stability of the robot when it moves.

[0018] Among them, a fixing block 21 is fixedly installed on the outer surface of the slide rail 20, a bracket 22 is fixedly installed at the bottom end of the fixing block 21, and a photovoltaic panel 23 is fixedly installed at the top end of the bracket 22.

[0019] The bracket 22 serves as the installation platform for the photovoltaic panel 23 and can stably support the slide rail 20 through the fixing block 21.

[0020] The outer surface of the housing 1 is fixedly mounted with a fixed shell 24, the top of the fixed shell 24 is provided with a fan 25, the inside of the fixed shell 24 is fixedly mounted with a guide block 27, the outer surface of the guide block 27 is slidably connected with a filter plate 28, the outer surface of the filter plate 28 is slidably connected with the inside of the fixed shell 24, and the front end of the filter plate 28 is fixedly mounted with a pull ring 29.

[0021] The fixed housing 24 provides installation space for components such as the fan 25 and filter plate 28. When the fan 25 is running, it can send airflow into the fixed housing 24. The guide block 27 can guide the installation of the filter plate 28, ensuring that the filter plate 28 is accurately embedded in the fixed housing 24. The filter plate 28 can filter the airflow entering the fixed housing 24, preventing impurities from being blown towards the photovoltaic panel 23 with the airflow. The pull ring 29 makes it easy for the operator to pull the filter plate 28, facilitating the removal and installation of the filter plate 28.

[0022] The fixed shell 24 has a heating wire 26 inside, and a support block 36 is fixedly sleeved on the outer surface of the heating wire 26. The support block 36 is fixedly connected to the inside of the fixed shell 24. The support block 36 provides fixed support for the heating wire 26, ensuring that the heating wire 26 is in a stable position within the fixed housing 24. When the heating wire 26 is running, it can heat the airflow sent into the fixed housing 24 by the fan 25, turning the airflow into hot air, so as to better dry the cleaned photovoltaic panel 23.

[0023] Among them, an arc-shaped block 30 is fixedly installed on the outer surface of the fixed shell 24, a lever 31 is slidably connected inside the arc-shaped block 30, a spring 32 is fixedly installed at the top of the lever 31, and the top of the spring 32 is fixedly connected to the inside of the arc-shaped block 30.

[0024] The arc-shaped block 30 provides a mounting base for the paddle 31 and the spring 32. The paddle 31 can slide along the inside of the arc-shaped block 30, and its movement can drive the related components to move. The spring 32 is compressed when the paddle 31 is paddled, and after release, it can use its elasticity to drive the paddle 31 to return to its original position. The bottom end of the paddle 31 is fixedly installed with a rod 33, and the bottom end of the rod 33 is inserted into the inside of the pull ring 29. When the bottom end of the insertion rod 33 is inserted into the pull ring 29, the filter plate 28 can be locked in the fixed shell 24 to prevent the filter plate 28 from falling off during robot operation. When the insertion rod 33 is disengaged from the pull ring 29, the filter plate 28 can be removed, thereby realizing the quick locking and unlocking of the filter plate 28.

[0025] The top of the housing 1 is fixedly equipped with a transmitter 34 and a controller 35. The transmitter 34 is electrically connected to the controller 35, and the controller 35 is electrically connected to the motor 12, the fan 25, the liquid pump 37 and the heating wire 26.

[0026] The transmitter 34 receives signals from the operator and transmits them to the controller 35. The controller 35, through electrical connection with the motor 12, fan 25, liquid pump 37 and heating wire 26, can control the operation and stop of these components, thereby realizing the robot's automated cleaning operation of the photovoltaic panel 23.

[0027] Working principle and usage process of this utility model: Due to the design of the bracket 22, it will serve as the installation platform for the photovoltaic panel 23 and can provide good support for the slide rail 20 through the fixing block 21. When the operator needs to clean the photovoltaic panel 23, the operator first sends a signal to the transmitter 34, which then sends a signal to the controller 35. The controller 35 then controls the operation of the motor 12, fan 25, liquid pump 37, and heating wire 26. When the liquid pump 37 is running, cleaning fluid is delivered into the liquid pump 37 inlet pipe 9. Subsequently, this cleaning fluid will flow into the hollow shaft 8 through the liquid inlet pipe 9. At this time, the cleaning fluid inside the hollow shaft 8 will be sprayed out through the through hole on the hollow shaft 8 and the water outlet hole on the cleaning roller 10. When motor 12 is running, shaft 13 will drive fourth gear 14 to rotate. Since the outer surface of fourth gear 14 meshes with the outer surface of first gear 4, when fourth gear 14 rotates, it will drive long shaft 3 to rotate inside the housing 1 through first gear 4. At this time, long shaft 3 will simultaneously drive two drive wheels 5 and two second gears 6 to rotate. At this time, two drive wheels 5 will roll forward along the inside of two slide rails 20, thereby causing the robot to move to the left as a whole. At the same time, two driven wheels 19 will also roll inside slide rails 20. Due to the cooperation of driven wheels 19 and drive wheels 5, the robot can move to the left stably. Furthermore, the protective shell 16 will ensure the stable operation of the internal transmission structure by wrapping long shaft 3, hollow shaft 8, second gear 6 and third gear 7. Since the outer surfaces of the two second gears 6 are respectively meshed with the outer surfaces of the two third gears 7, when the two second gears 6 rotate, they will drive the hollow shaft 8 to rotate through the two third gears 7. Since the liquid inlet pipe 9 is movably connected to the hollow shaft 8, the liquid inlet pipe 9 will not be affected by the rotation of the hollow shaft 8. At this time, the hollow shaft 8 will drive the cleaning roller 10 to rotate. When the rotating cleaning roller 10 contacts the photovoltaic panel 23 during the leftward movement, the brush on its outer surface will cooperate with the cleaning liquid sprayed from the water outlet to perform a brushing operation on the photovoltaic panel 23. Meanwhile, when the fan 25 and the heating wire 26 are running, the fan 25 will blow air into the interior of the fixed shell 24, and the heating wire 26 will heat the blown air. Due to the support block 36 supporting the heating wire 26, the heating process will be stable. The heated air will then be filtered by the filter plate 28. Due to the action of the guide block 27, the filter plate 28 can be stably installed in the fixed shell 24. The filtered hot air will then be blown directly to the top of the photovoltaic panel 23 to achieve the drying effect. When the filter plate 28 needs cleaning or replacement due to dust clogging the sieve holes after prolonged use, the operator first moves the lever 31 upwards, causing it to move upwards along the inside of the arc-shaped block 30. During this process, the spring 32 will be compressed, and at the same time, the insertion rod 33 will move upwards under the action of the lever 31 and disengage from the pull ring 29. At this time, the filter plate 28 will be unlocked, and the operator can pull the pull ring 29 to pull the filter plate 28 out of the fixed housing 24. When the filter plate 28 needs to be reinstalled, the operator moves the lever 31 upwards again to move the insertion rod 33 upwards, and then inserts the filter plate 28 into the fixed housing 24 along the guide block 27. After the filter plate 28 is installed in place, the lever 31 is released. Due to the elastic force of the spring 32, the lever 31 will drive the insertion rod 33 downwards to reset and re-insert into the pull ring 29, thus completing the fixing of the filter plate 28.
