Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic panel cleaning, in particular to an online solar panel obstacle avoidance cleaning machine. Background Art

[0002] During the cleaning process, solar panels in distributed photovoltaic power generation systems often encounter obstacles such as axial fans and chimneys. Existing solar panel cleaning devices are unable to avoid obstacles and must instead be equipped with one or more independently operated cleaning devices on either side of the obstacle. Due to the limited area and space available on rooftops and other supporting surfaces for solar panels, installing too many cleaning devices is sometimes impractical. Even if installation is possible, excessive numbers of cleaning devices can negatively impact the bearing capacity of the roof structure and other mounting surfaces. As the number of cleaning devices increases, the failure rate of the cleaning devices also increases. Furthermore, the high cost of cleaning devices incurs additional costs, negatively impacting the overall investment and maintenance of the photovoltaic power generation system.

[0003] For example, the existing Chinese patent document CN202110154780.5 discloses a solar panel obstacle avoidance cleaning device and cleaning method, the cleaning device includes a cleaning mechanism for cleaning the solar panel during movement, and a driving mechanism for driving the cleaning mechanism to move, the cleaning mechanism includes a first cleaning part and a second cleaning part that can be connected as one, when the first cleaning part and the second cleaning part connected as one move to a predetermined distance from the obstacle, the first cleaning part and the second cleaning part are separated and form a gap, after the obstacle passes through the gap, the first cleaning part and the second cleaning part are connected as one again; when cleaning the solar panel, the cleaning device avoids the obstacle through the separated first cleaning part and the second cleaning part, and there is no need to install independently operating cleaning devices on both sides of the obstacle, which reduces the number of cleaning devices installed, reduces the impact on the bearing capacity of the installation surface, and reduces the failure rate of the device, thereby achieving the effect of reducing costs and increasing efficiency in cleaning solar panels; While the aforementioned cleaning device has the ability to avoid obstacles and efficiently clean photovoltaic panels, the obstacle avoidance process involves a series of complex structures and equipment. Specifically, these include key components such as proximity switches, control systems, and telescopic arms. These electrical components require additional power to operate, so the energy supply must be increased while the cleaning device is reciprocating. This not only increases energy consumption but also incurs additional power supply costs. Furthermore, when using the system to avoid obstacles outdoors, sensitive components such as proximity switches are susceptible to external weather conditions, such as rain and high temperatures, which can lead to damage or performance degradation. In this case, not only are regular maintenance and inspections required, but damaged components may also need to be replaced, further increasing maintenance costs. Therefore, while the cleaning device performs well in terms of functionality, its complexity and maintenance costs are significant issues in practical applications. Summary of the Invention

[0021] In this solution, the designed reciprocating drive mechanism 5 can drive the cleaning brush 3 to perform reciprocating motion, thereby cleaning the surface of the solar photovoltaic panel 1. At the same time, when the cleaning brush 3 moves to the position of the trigger mechanism 6, it will trigger the rotation mechanism 4 to work. The rotation mechanism 4 drives the cleaning brush 3 to rotate a certain angle so that it will not collide with the obstacle 2 during displacement movement. After crossing the obstacle 2, the cleaning brush 3 can automatically reset to its initial position, and efficiently clean the two solar photovoltaic panels 1. When performing obstacle avoidance actions, the key parts of the rotation mechanism 4 are lubricated by the oiling mechanism 7 to ensure that the key parts of the rotation mechanism 4 are fully lubricated.

[0022] For further information, see Figure 3 and Figure 4 The rotating mechanism 4 includes a first L-shaped plate 8 fixed to one end of the top of the cleaning brush 3, a rotating plate 9 is fixed to one side of the first L-shaped plate 8, and a rotating rod 10 is fixed to the inner side of the rotating plate 9. The outer side of the rotating rod 10 is rotatably connected to the first U-shaped plate 11 through a bearing, and one end of the first U-shaped plate 11 is rotatably connected to the rotating shaft 12 through a bearing. The middle part of the rotating shaft 12 is fixedly sleeved with a first gear 13, and the middle part of the rotating rod 10 is fixedly sleeved with a second gear 14, and the first gear 13 and the second gear 14 are meshed and connected. The outer side of the rotating rod 10 and the upper side of the second gear 14 are also fixedly sleeved with a third gear 15, and a connecting plate 16 is fixed on one side of the first U-shaped plate 11. The oiling mechanism 7 is mounted on the connecting plate 16, and the output end of the reciprocating drive mechanism 5 is fixedly connected to the connecting plate 16.

[0023] The transmission is carried out through the first gear 13 and the rack on the trigger mechanism 6, thereby driving the first gear 13 to rotate, the first gear 13 drives the second gear 14 to rotate, the second gear 14 drives the rotating rod 10 to rotate, the rotating rod 10 drives the rotating plate 9 to rotate, the rotating plate 9 drives the first L-shaped plate 8 to rotate, and the first L-shaped plate 8 drives the cleaning brush 3 to rotate a certain angle, so that the cleaning brush 3 moves to the position of the obstacle 2 and just rotates to the appropriate position so that it does not touch the obstacle 2. After crossing the obstacle 2, the third gear 15 will transmit to the other rack on the trigger mechanism 6, thereby driving the third gear 15 to rotate, the third gear 15 drives the rotating rod 10 to rotate in the opposite direction, and finally drives the cleaning brush 3 to rotate in the opposite direction by the same angle to the initial position, so that the cleaning brush 3 can smoothly rotate to a horizontal state before contacting the next solar photovoltaic panel 1.

[0024] For further information, see Figure 4 The reciprocating drive mechanism 5 includes a first Z-shaped plate 17 fixedly connected to the end of the solar photovoltaic panel 1, and a reciprocating screw 18 is rotatably connected between the first Z-shaped plates 17 on the left and right sides. The outer side of the reciprocating screw 18 is threadedly sleeved with a moving block 19, and the top of the moving block 19 is fixedly connected to the bottom of the connecting plate 16. A second U-shaped plate 20 is fixed to one side of the moving block 19, and the moving block 19 is fixedly connected to a slider 21 through the second U-shaped plate 20. A slide rail 22 adapted to the slider 21 is fixed to one side of the solar photovoltaic panel 1, and a control box 23 is fixed to one side of one of the first Z-shaped plates 17. A drive motor 24 is installed inside the control box 23, and a fourth gear 25 is fixed to the output end of the drive motor 24. A fifth gear 26 is meshed with one side of the fourth gear 25, and the fifth gear 26 is fixedly connected to one end of the reciprocating screw 18.

[0025] The fourth gear 25 is driven to rotate by the driving motor 24, the fourth gear 25 drives the fifth gear 26 to rotate, the fifth gear 26 drives the reciprocating screw 18 to rotate, the reciprocating screw 18 drives the moving block 19 to reciprocate, thereby driving the rotating mechanism 4 and the cleaning brush 3 to reciprocate, and then the surfaces of the two solar photovoltaic panels 1 are cleaned by the moving cleaning brush 3.

[0026] For further information, see Figure 5 The trigger mechanism 6 shown in the figure includes a third U-shaped plate 27 fixedly connected to the two first Z-shaped plates 17, a T-shaped frame 28 is fixed to the middle of the third U-shaped plate 27, and a first rack 29 and a second rack 30 are fixed to both ends of the T-shaped frame 28, the first rack 29 and the first gear 13 are matched in position, and the second rack 30 and the third gear 15 are matched in position; Among them, see Figure 3 andFigure 5 , the gear ratio of the first gear 13 and the first rack 29 is two to one, the gear ratio of the third gear 15 and the second rack 30 is four to one, the gear ratio of the first gear 13 and the second gear 14 is one to two, and the gear ratio of the third gear 15 and the second gear 14 is one to one, so that the first gear 13 will rotate half a turn after engaging with the first rack 29, and the second gear 14 will rotate a quarter turn, thereby driving the cleaning brush 3 to rotate ninety degrees before the first gear 13 and the first rack 29 are disengaged, and the third gear 15 and the second rack 30 will rotate a quarter turn during the process of engaging and disengaging, so that the first gear 13 and the second gear 14 can return to their original positions quickly, and also ensure that the cleaning brush 3 is reversed ninety degrees, thereby returning to the state when the first gear 13 and the first rack 29 are just engaged.

[0027] When the first gear 13 moves to engage with the first rack 29, it will drive the first gear 13 to rotate clockwise, and the first gear 13 will drive the second gear 14 to rotate counterclockwise. The second gear 14 will drive the cleaning brush 3 to rotate counterclockwise by driving the rotating rod 10 to rotate. It will just rotate to an unobstructed position before encountering the obstacle 2, and then the cleaning brush 3 will continue to move until the third gear 15 and the second rack 30 are engaged. The third gear 15 will rotate clockwise, driving the rotating rod 10 to rotate and then driving the cleaning brush 3 to rotate clockwise, thereby returning the first gear 13, the second gear 14 and the cleaning brush 3 to their initial state, that is, after successfully passing the obstacle 2, the cleaning brush 3 will be automatically adjusted to rotate to contact the next solar photovoltaic panel 1.

[0028] For further information, see Figure 2 A second Z-shaped plate 47 is fixedly connected to the outer side of the connecting plate 16. When in the non-working state, one side of the second Z-shaped plate 47 fits against the outer side of the cleaning brush 3. This design can limit the cleaning brush 3 and ensure that it does not rotate at will when in the non-working state; secondly, this structure can also prevent the cleaning brush 3 from rotating beyond the necessary angle, thereby avoiding possible damage to the equipment or adverse effects on the cleaning effect.

[0029] For this program, please refer to Figures 1-9 , the process of cleaning solar panels; First, in the initial position, the cleaning brush 3 is at the uppermost side of the first solar photovoltaic panel 1, and the cleaning brush 3 is placed horizontally with the brush surface in contact with the surface of the solar photovoltaic panel 1. During operation, the reciprocating screw 18 rotates, driving the moving block 19 to move, and the moving block 19 drives the rotating mechanism 4 and the cleaning brush 3 to move as well. At this time, the cleaning brush 3 cleans the first solar panel; Afterwards, before the cleaning brush 3 encounters the obstacle 2, the first gear 13 moves to a state where it is meshed with the first rack 29. When it continues to move, it drives the first gear 13 to rotate clockwise. Through the transmission action of the second gear 14, the rotating rod 10 and the rotating plate 9, the cleaning brush 3 is driven to rotate exactly ninety degrees before the first gear 13 and the first rack 29 are disengaged. That is, before encountering the obstacle 2, the cleaning brush 3 is automatically rotated to a position where it does not collide with the obstacle 2 through the movement of the mechanical parts. Then, after leaving the obstacle 2 and before entering the second solar photovoltaic panel 1, the third gear 15 will enter into a meshing state with the second rack 30 in advance, and the third gear 15 will rotate clockwise, driving the rotating rod 10 to rotate and then driving the cleaning brush 3 to rotate clockwise, so that the first gear 13, the second gear 14 and the cleaning brush 3 return to the initial state, that is, after successfully passing the obstacle 2, the cleaning brush 3 is automatically adjusted to rotate to contact the next solar photovoltaic panel 1, and the reciprocating screw 18 continues to rotate to drive the cleaning brush 3 to clean the next solar panel; Finally, the cleaning brush 3 performs a return motion. During the motion, the third gear 15 will first mesh with the second rack 30, and the third gear 15 will rotate counterclockwise. Before the third gear 15 and the second rack 30 disengage, the cleaning brush 3 rotates at an angle of ninety degrees. After continuing to move and successfully passing the obstacle 2, the first gear 13 will then enter into a meshing state with the first gear 13. The first gear 13 rotates counterclockwise and the second gear 14 rotates clockwise, thereby driving the cleaning brush 3 to rotate ninety degrees clockwise, so that the first gear 13, the second gear 14 and the cleaning brush 3 return to the initial state, and the reciprocating screw 18 continues to rotate to drive the cleaning brush 3 to clean the solar panel.

[0030] Example 2: Please refer to Figure 2 、 Figures 6-8 This embodiment further explains the first embodiment, and the difference lies in that the transmission components of the rotating mechanism 4 are optimized.

[0031] Specifically, the oil filling mechanism 7 includes an oil storage cylinder 31 fixed to the top of the connecting plate 16, a fixed plate 32 is fixedly connected to the middle of the connecting plate 16, a sealed piston box 33 is fixed to one end of the fixed plate 32, the inner side of the sealed piston box 33 is slidably connected to the piston plate 34 through a sealing ring, a liquid inlet check valve 35 and a first liquid outlet check valve 36 are respectively embedded and installed on the top of the sealed piston box 33, the top of the liquid inlet check valve 35 is fixedly connected to a liquid inlet pipe 37, one end of the liquid inlet pipe 37 is connected to the interior of the oil storage cylinder 31, the top of the first liquid outlet check valve 36 is fixedly connected to a first liquid outlet pipe 38, the end of the first liquid outlet pipe 38 away from the sealed piston box 33 is close to the meshing position of the first gear 13 and the second gear 14, and a swinging member 39 is provided at the bottom of the rotating shaft 12; At the same time, the swinging member 39 includes a rocker rod 40 fixedly connected to the bottom of the rotating shaft 12, and a limit pin 41 is fixed to the bottom of the rocker rod 40 and one end away from the rotating shaft 12.

One end of the piston plate 34 is fixedly connected to the reciprocating rod 43, and the reciprocating rod 43 is slidably penetrated and connected to one end of the sealed piston box 33.

[0032] During the meshing rotation of the first gear 13 and the first rack 29, the rocker arm 40 at the bottom of the rotating shaft 12 will also be driven to rotate, and the rotation angle is 180 degrees clockwise. At this time, the rocker arm 40 will drive the limit pin 41 to slide in the slot plate 42, thereby driving the slot plate 42 to move horizontally. The slot plate 42 drives the reciprocating rod 43 to move horizontally, and the reciprocating rod 43 drives the piston plate 34 to slide in the sealed piston box 33. Since the rotation angle is 180 degrees, the piston plate 34 just moves from one extreme position to another extreme position.

At this time, the piston plate 34 also moves from one extreme position to another extreme position. At this time, the liquid inlet one-way valve 35 is opened and the first liquid outlet one-way valve 36 is closed, and the lubricating oil in the oil reservoir 31 is sucked into the sealed piston box 33, preparing for the next oil injection lubrication action.

[0033] At the same time, it is worth noting that a sealing cap 46 is threadedly connected to the top of the oil storage cylinder 31 , and the oil storage cylinder 31 adopts a transparent hard PVC tube, so that it is convenient for personnel to add lubricating oil.

[0034] Example 3: Please refer to Figures 6-8This embodiment further explains the second embodiment, and the difference is that the operation of the reciprocating screw 18 is optimized.
