Description

Technical Field

[0001] This invention relates to the field of photovoltaic cleaning technology, specifically to an auxiliary cleaning device for photovoltaic cleaning robots. Background Technology

[0002] Photovoltaic power plants, as a representative of renewable energy, have become an important part of the modern energy structure due to their clean, environmentally friendly, and renewable advantages. However, photovoltaic panels are exposed to the elements for extended periods, making them susceptible to dust accumulation, which can block sunlight and affect power generation efficiency. Since photovoltaic panels are mostly installed with tilted supports, traditional manual cleaning is not only inefficient but also unsafe. Improper operation or falls can lead to worker injuries and damage to the panels. To address this issue, photovoltaic cleaning robots have emerged. These robots operate on a simple and efficient principle, autonomously planning their cleaning paths.

[0003] Existing photovoltaic (PV) cleaning robots clean PV panels using rollers that drive brushes. However, this method is mostly limited to removing surface dust and other loose particles. When stubborn stains, such as rain-soaked dust or accumulated dirt, accumulate and become difficult to remove, existing robots struggle to clean them effectively. Furthermore, the cleaning components on these robots are not easily disassembled, requiring cleaning or replacement after prolonged use, thus impacting the robot's usability and cleaning efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary cleaning device for photovoltaic cleaning robots to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary cleaning device for a photovoltaic cleaning robot, comprising a protective cover, wherein a supporting horizontal plate is provided in the inner cavity of the protective cover, and docking plates are symmetrically engaged at the left and right ends of the supporting horizontal plate. Support frames are fixedly connected to the sides of the two docking plates that are far apart from each other.

[0010] The left and right shaking mechanism includes a shaking sleeve fitted onto a support plate. The lower end of the shaking sleeve has a through groove, which is located below the connecting groove. Positioning blocks are symmetrically fixedly connected to the left and right sides of the inner cavity of the shaking sleeve. A guide block is fixedly connected to the upper end of the inner cavity of the shaking sleeve. The guide block is slidably connected to the guide groove. Round shafts are symmetrically installed at both ends of the inner cavity of the shaking sleeve. The two ends of the two round shafts are rotatably connected to the adjacent positioning blocks through bearings. The two ends of the round shafts pass through the adjacent positioning blocks and are fixedly connected to the transmission gears. The transmission gears are located on the outside of the positioning blocks. A shaking drive assembly is installed on one of the round shafts. The cleaning mechanism is fitted onto the shaking sleeve.

[0011] As a further embodiment of the present invention, the vibration drive assembly includes a drive sleeve fixedly sleeved on a round shaft. The cylindrical surface of the drive sleeve is provided with a wave groove. A drive column is slidably connected in the wave groove. A fixing block is fixedly connected to the end of the drive column away from the wave groove. The fixing block is fixedly connected to the side of the support plate.

[0012] As a further embodiment of the present invention, the cleaning mechanism includes a transmission belt sleeved on the outside of the vibrating sleeve. Multiple cleaning rods are fixedly connected at equal intervals on the outer side of the transmission belt. Multiple water outlet holes are equidistantly opened on the side of the transmission belt. The transmission belt slides in contact with the outer side of the vibrating sleeve. Toothed belts are symmetrically fixedly connected on the left and right sides of the transmission belt. Two toothed belts are respectively locked on the left and right sides of the vibrating sleeve. The inner side of the toothed belts meshes with transmission gears at the adjacent ends of two round shafts. A regular polygonal insert is fixedly connected to the outer side of one of the transmission gears near the drive mechanism.

[0013] As a further embodiment of the present invention, the driving mechanism includes a rotating column rotatably mounted on the inner side wall of the protective cover. The rotating column is driven by the motor shaft of a servo motor fixedly mounted on the outer side of the protective cover. A regular polygonal shrinkage groove is provided at one end of the rotating column near the regular polygonal plug. A sliding groove is symmetrically provided on the inner side wall of the regular polygonal shrinkage groove. A transmission mechanism is slidably mounted at one end of the regular polygonal shrinkage groove near the regular polygonal plug.

[0014] As a further embodiment of the present invention, the transmission mechanism includes a regular polygonal slide column that is slidably installed in a regular polygonal contraction groove. A limit slider is symmetrically fixedly connected to one end of the regular polygonal slide column in the regular polygonal contraction groove. A synchronous rotating seat is fixedly connected to the other end of the regular polygonal slide column outside the regular polygonal contraction groove. A regular polygonal slot is opened at one end of the synchronous rotating seat near the regular polygonal insert. An adjusting sleeve is fixedly sleeved on the synchronous rotating seat. A return spring is sleeved at the other end of the regular polygonal slide column outside the regular polygonal contraction groove.

[0015] As a further embodiment of the present invention, the regular polygonal plug is inserted into the regular polygonal slot, the two limiting sliders are respectively slidably connected to the adjacent sliding grooves, and the two ends of the reset spring abut against the rotating column and the synchronous rotating seat respectively.

[0016] The beneficial effects of this invention are:

[0017] 1. During assembly, first push the adjusting sleeve to move the synchronous rotating seat closer to the rotating column. At the same time, the synchronous rotating seat drives the regular polygonal sliding column to insert into the regular polygonal shrinkage groove. Then, insert the support horizontal plate from front to back between the two docking plates. Lock the docking plate and the support horizontal plate through the locking mechanism. At this time, the docking plate cannot be separated from the docking groove. Then, release the adjusting sleeve. Under the action of the return spring, the synchronous rotating seat moves closer to the regular polygonal insert until the regular polygonal insert is fully inserted into the regular polygonal slot, thus completing the assembly. During disassembly, separate the regular polygonal slot of the synchronous rotating seat from the regular polygonal insert. At the same time, pull the two pull rods outward along the concave plate to move the end of the locking block out of the slot. At this time, the support horizontal plate can be moved forward from between the two docking plates. The support horizontal plate drives the left and right shaking mechanism and the cleaning mechanism to move out of the protective cover, completing the disassembly. The locking mechanism allows for easy installation and disassembly of the support horizontal plate, the left and right shaking mechanism, and the cleaning mechanism, facilitating the cleaning, maintenance, or replacement of the equipment later, and greatly improving work efficiency.

[0018] 2. During operation, connect the protective cover to the photovoltaic cleaning robot, place the photovoltaic cleaning robot and the protective cover on the upper part of the photovoltaic panel to be cleaned, and the photovoltaic cleaning robot drives the protective cover to move along the upper part of the photovoltaic panel. At the same time, the external water pipe supplies water to the water inlet pipe, and the servo motor starts. When the protective cover moves, it drives the cleaning mechanism to move, so that the cleaning mechanism can clean the upper part of the photovoltaic panel.

[0019] 3. The water inlet pipe sends water into the water inlet tank, and the water flows along the water inlet tank into the connecting tank and the through tank. When the water flows into the through tank, the water will spray downwards along the water outlet located below the through tank, thereby rinsing the stains on the upper part of the photovoltaic panel.

[0020] 4. Simultaneously, the servo motor shaft drives the rotating column to rotate, which in turn drives the drive mechanism to rotate the transmission mechanism. The transmission mechanism drives the regular polygonal plug to rotate synchronously, and the regular polygonal plug drives the left and right shaking mechanism to vibrate back and forth. The left and right shaking mechanism drives the cleaning mechanism to rotate back and forth while vibrating back and forth, so that the cleaning rod can effectively clean the stubborn stains on the upper part of the photovoltaic panel. While the transmission belt vibrates left and right, the water sprayed from the water outlet at the lower end of the transmission belt also moves left and right. Through the cleaning rod and the sprayed water, the cleaning effect on the stains is improved, greatly improving the cleaning effect on the photovoltaic panel. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 10This invention provides a technical solution: an auxiliary cleaning device for a photovoltaic cleaning robot, including a protective cover 1. A connecting seat is fixedly installed on the rear side of the protective cover 1. The connecting seat is used to install and connect with the photovoltaic cleaning robot. The connection between the connecting seat and the photovoltaic cleaning robot can be by snap-fit, bolt connection, or insertion through a pin, etc. The lower end and front end of the protective cover 1 are open. A supporting horizontal plate 2 is provided in the inner cavity of the protective cover 1. A docking plate 3 is symmetrically snapped onto the left and right ends of the supporting horizontal plate 2. A support frame 31 is fixedly connected to the side of the two docking plates 3 that are far apart from each other. One support frame 31 is fixedly connected to the inner side wall of the protective cover 1 through a connecting plate, and the other support frame 31 is directly fixedly connected to the inner side wall of the protective cover 1. The docking plate 3 and the supporting horizontal plate 2 are connected by a locking mechanism. A left and right shaking mechanism is sleeved on the supporting horizontal plate 2. A cleaning mechanism is sleeved on the outside of the left and right shaking mechanism. A driving mechanism for driving the cleaning mechanism to rotate is installed on the inner side wall of the protective cover 1. The driving mechanism and the cleaning mechanism are connected by a transmission mechanism.

[0034] Please see Figure 2 The lower ends of the left and right side plates of the protective cover 1 are recessed upwards and have mounting grooves. Multiple rollers are equidistantly connected in the mounting grooves through rotating shafts.

[0035] When the photovoltaic cleaning robot moves the protective cover 1 along the upper end of the photovoltaic panel, the rollers on the lower ends of the two side plates of the protective cover 1 roll along the upper end of the photovoltaic panel.

[0036] Please see Figure 5 , Figure 6 and Figure 9 The left and right ends of the supporting horizontal plate 2 are symmetrically provided with docking grooves 21. The rear end of the docking groove 21 passes through the supporting horizontal plate 2. The rear end of the inner side wall of the two docking grooves 21 is provided with a slot 22. The docking plate 3 is engaged with the docking groove 21.

[0037] The locking mechanism includes a concave plate 33 fixedly installed on the side of the docking plate 3. A locking block 34 is provided on the inner side of the concave plate 33. A pull rod 35 is slidably connected to the side of the concave plate 33. One end of the pull rod 35 extends through the side of the concave plate 33 to its inner side. The end of the pull rod 35 on the inner side of the concave plate 33 is fixedly connected to the locking block 34. A spring piece 36 is symmetrically fixedly installed on the side of the locking block 34. The side of the spring piece 36 away from the locking block 34 abuts against the inner side of the concave plate 33. One end of the locking block 34 passes through the docking plate 3 and engages with the locking groove 22. The locking block 34 is slidably connected to the docking plate 3. An inclined surface is provided on the front side of the end of the locking block 34 away from the pull rod 35.

[0038] When it is necessary to install the support plate 2, insert the support plate 2 between the two mating plates 3 from front to back, so that the two mating grooves 21 at both ends of the support plate 2 respectively engage with the two mating plates 3. During the engagement process, the inclined surface of the locking block 34 first engages with the mating groove 21. At this time, the support plate 2 pushes the locking block 34 to move into the concave plate 33, and the locking block 34 squeezes the spring piece 36.

[0039] When the docking plate 3 is fully inserted into the docking groove 21, the end of the locking block 34 is aligned with the groove 22. Under the action of the elastic force of the spring piece 36, the end of the locking block 34 is inserted into the groove 22, thereby fixing the docking plate 3 and the docking groove 21 relatively. The locking mechanism locks the docking plate 3 and the supporting horizontal plate 2, so that the docking plate 3 cannot be separated from the docking groove 21.

[0040] When it is necessary to remove the support plate 2 from between the two mating plates 3, first pull the two pull rods 35 outward along the concave plate 33. The pull rods 35 drive the locking block 34 to move, so that the end of the locking block 34 moves out of the locking groove 22. At this time, the support plate 2 can be moved forward from between the two mating plates 3 to complete the removal of the support plate 2.

[0041] Please see Figure 4 , Figure 5 , Figures 7 to 9 The upper end of the supporting horizontal plate 2 is provided with a guide groove 25. The inner side wall of the docking groove 21 at one end of the supporting horizontal plate 2 is provided with a water inlet groove 23. The lower end of the supporting horizontal plate 2 is provided with a connecting groove 24, which is connected to the water inlet groove 23. A water inlet pipe 32 is inserted through the side of a docking plate 3 near the water inlet groove 23. The water inlet pipe 32 is fixedly connected to the docking plate 3 and is connected to the water inlet groove 23. The upper end of the water inlet pipe 32 passes through the upper end of the protective cover 1 and extends to the outside. A connector is fixedly installed at the upper end of the water inlet pipe 32. The connector is used to connect to an external water pipe to supply water to the water inlet pipe 32.

[0042] The external water pipe can move with the photovoltaic cleaning robot. The other end of the external water pipe is connected to the water pump, and the water pump sends water into the inlet pipe 32 through the external water pipe.

[0043] The left and right shaking mechanism includes a shaking sleeve 4 sleeved on the support horizontal plate 2. The lower end of the shaking sleeve 4 is provided with a through groove 41. The through groove 41 is located below the connecting groove 24 and is connected to the connecting groove 24. The connecting groove 24 and the through groove 41 form a water collection cavity. The water inlet pipe 32 sends water into the water inlet groove 23. The water flows along the water inlet groove 23 into the connecting groove 24 and the through groove 41, that is, it is collected in the water collection cavity.

[0044] Positioning blocks 42 are symmetrically fixedly connected to the left and right sides of the inner cavity of the vibrating sleeve 4. A guide block 43 is fixedly connected to the upper end of the inner cavity of the vibrating sleeve 4. The guide block 43 is slidably connected to the guide groove 25. Round shafts 5 are symmetrically installed at both ends of the inner cavity of the vibrating sleeve 4. The two ends of the two round shafts 5 are respectively rotatably connected to the adjacent positioning blocks 42 through bearings. Limiting rings are symmetrically fixedly sleeved on the round shafts 5. The limiting rings are in rotatable contact with the inner side of the positioning blocks 42. The positioning blocks 42 support and limit the round shafts 5. The two ends of the round shafts 5 pass through the adjacent positioning blocks 42 and are fixedly connected to the transmission gears 51. The transmission gears 51 are set on the outer side of the positioning blocks 42. A vibrating drive assembly is installed on one of the round shafts 5. The cleaning mechanism is sleeved on the vibrating sleeve 4.

[0045] The vibration drive assembly includes a drive sleeve 52 fixedly sleeved on a round shaft 5. The cylindrical surface of the drive sleeve 52 is provided with a wave groove 53. A drive column 57 is slidably connected in the wave groove 53. A fixing block 56 is fixedly connected to the end of the drive column 57 away from the wave groove 53. The fixing block 56 is fixedly connected to the side of the support plate 2.

[0046] When the circular shaft 5 rotates, it drives the drive sleeve 52 to rotate. The drive sleeve 52 drives the wave groove 53 to rotate along the drive column 57. At this time, when the wave groove 53 slides along the drive column 57, the drive column 57 squeezes the wave groove 53, causing the drive column 57 and the wave groove 53 to abut against each other. Since the drive column 57 is fixedly installed on the support plate 2 by the fixing block 56, it can only drive the sleeve 52 to move, thus moving the drive sleeve 52 to the left or right. As the circular shaft 5 continues to rotate, the drive sleeve 52 vibrates back and forth along the drive column 57. The drive sleeve 52 drives the circular shaft 5 to vibrate back and forth synchronously. The circular shaft 5 drives the vibrating sleeve 4 to vibrate back and forth synchronously through the positioning block 42, causing the vibrating sleeve 4 to slide back and forth along the support plate 2. At the same time, the vibrating sleeve 4 drives the guide block 43 to slide back and forth along the guide groove 25, thus enabling the vibrating sleeve 4 to move back and forth stably.

[0047] During the left and right shaking of the vibrating sleeve 4, the through groove 41 at the lower end of the vibrating sleeve 4 and the connecting groove 24 at the lower end of the supporting horizontal plate 2 are always in a connected state.

[0048] Please see Figure 3 , Figure 4 , Figure 7 and Figure 8The cleaning mechanism includes a transmission belt 6 sleeved on the outside of the vibrating sleeve 4. Multiple cleaning rods 61 are fixedly connected at equal intervals on the outer side of the transmission belt 6. Multiple water outlet holes 62 are equidistantly opened on the side of the transmission belt 6. The transmission belt 6 slides in contact with the outer side of the vibrating sleeve 4. Toothed belts 54 are symmetrically fixedly connected on the left and right sides of the transmission belt 6. The two toothed belts 54 are respectively locked on the left and right sides of the vibrating sleeve 4. The left and right sides of the transmission belt 6 correspond one-to-one with the left and right sides of the vibrating sleeve 4 and are on the same vertical plane. Through the two toothed belts 54 locked on the left and right sides of the vibrating sleeve 4, the transmission belt 6 can be firmly sleeved on the vibrating sleeve 4, so that the transmission belt 6 and the toothed belts 54 can move synchronously with the vibrating sleeve 4.

[0049] As the drive belt 6 rotates along the vibrating sleeve 4, the water outlet holes 62 on the drive belt 6 move sequentially from below the through groove 41. When water flows into the through groove 41, the water will spray downwards along the water outlet holes 62 located below the through groove 41, thereby rinsing the stains on the upper part of the photovoltaic panel.

[0050] The inner side of the toothed belt 54 meshes with the transmission gears 51 at the adjacent ends of the two round shafts 5. The two transmission gears 51 are distributed at the front and rear ends of the inner side of the toothed belt 54. That is, the toothed belt 54 on the left side of the vibrating sleeve 4 meshes with the transmission gears 51 at the left end of the two round shafts 5, and the toothed belt 54 on the right side of the vibrating sleeve 4 meshes with the transmission gears 51 at the right end of the two round shafts 5. A regular polygonal insert 55 is fixedly connected to the outer side of one of the transmission gears 51 near the drive mechanism.

[0051] The lower end of the cleaning rod 61 at the bottom of the transmission belt 6 is lower than the bottom end of the roller, so that when the transmission belt 6 rotates, the cleaning rod 61 can clean the upper end of the photovoltaic panel.

[0052] The regular polygonal insert 55 drives the transmission gear 51 to rotate, the transmission gear 51 drives the toothed belt 54 to rotate, the transmission gear 51 drives the transmission gear 51 at the other end of the toothed belt 54 to rotate, and the two transmission gears 51 inside the toothed belt 54 drive the two round shafts 5 to rotate. At this time, the drive sleeve 52 sleeved on the round shaft 5 rotates synchronously with the round shaft 5.

[0053] When the round shaft 5 rotates, the two transmission gears 51 at both ends rotate synchronously. The two transmission gears 51 at both ends of the round shaft 5 drive the two toothed belts 54 to rotate synchronously. The two toothed belts 54 drive the transmission belt 6 to rotate synchronously. The transmission belt 6 drives the cleaning rod 61 to rotate, so that the cleaning rod 61 cleans the stains on the upper part of the photovoltaic panel.

[0054] When the round shaft 5 rotates, it drives the drive sleeve 52 in the vibration drive assembly to rotate synchronously, causing the drive sleeve 52 to vibrate back and forth along the drive column 57. The drive sleeve 52 drives the vibration sleeve 4 to vibrate synchronously left and right through the round shaft 5 and the positioning block 42. The vibration sleeve 4 drives the toothed belt 54, the transmission belt 6, and the cleaning rod 61 to move back and forth left and right, causing the transmission belt 6 to vibrate left and right while rotating back and forth, so that the cleaning rod 61 can effectively clean the stubborn stains on the upper part of the photovoltaic panel.

[0055] When the drive belt 6 vibrates left and right, the water sprayed from the water outlet 62 at the lower end of the drive belt 6 will also move left and right, thereby improving the rinsing effect on the stains and further improving the cleaning effect on the stains on the photovoltaic panel.

[0056] Please see Figure 3 , Figure 5 , Figure 6 and Figure 10 The drive mechanism includes a rotating column 7 rotatably mounted on the inner side wall of the protective cover 1. The rotating column 7 is driven by the motor shaft of a servo motor fixedly mounted on the outer side of the protective cover 1. A regular polygonal shrinkage groove 71 is provided at one end of the rotating column 7 near the regular polygonal plug 55. A sliding groove 72 is symmetrically provided on the inner side wall of the regular polygonal shrinkage groove 71. A transmission mechanism is slidably mounted at one end of the regular polygonal shrinkage groove 71 near the regular polygonal plug 55.

[0057] The transmission mechanism includes a regular polygonal slide column 8 that is slidably installed in a regular polygonal contraction groove 71. One end of the regular polygonal slide column 8 inside the regular polygonal contraction groove 71 is symmetrically and fixedly connected to a limit slider 81. The other end of the regular polygonal slide column 8 outside the regular polygonal contraction groove 71 is fixedly connected to a synchronous rotating seat 82. A regular polygonal slot 83 is opened at the end of the synchronous rotating seat 82 near the regular polygonal insert block 55. An adjusting sleeve 84 is fixedly sleeved on the synchronous rotating seat 82. A return spring 85 is sleeved at the other end of the regular polygonal slide column 8 outside the regular polygonal contraction groove 71.

[0058] The regular polygonal insert 55 is inserted into the regular polygonal slot 83. The two limiting sliders 81 are slidably connected to the adjacent slide grooves 72. The limiting sliders 81 and slide grooves 72 cooperate to prevent the regular polygonal slide column 8 from slipping out of the regular polygonal contraction groove 71. The two ends of the return spring 85 abut against the rotating column 7 and the synchronous rotating seat 82 respectively. The return spring 85 applies a spring force to the synchronous rotating seat 82.

[0059] The rotating column 7, motor shaft, regular polygonal sliding column 8, synchronous rotating seat 82 and regular polygonal plug 55 all rotate on the same axis. The regular polygonal plug 55 rotates on the same axis as its adjacent transmission gear 51 and round shaft 5.

[0060] The servo motor shaft drives the rotating column 7 to rotate, and the rotating column 7 drives the synchronous rotating seat 82 to rotate synchronously through the regular polygonal sliding column 8. The synchronous rotating seat 82 drives the regular polygonal insert 55 to rotate synchronously, and the regular polygonal insert 55 drives the adjacent transmission gear 51 to rotate synchronously. The transmission gear 51 drives the round shaft 5 to rotate.

[0061] When the vibrating sleeve 4, transmission belt 6, positioning block 42, round shaft 5, and transmission gear 51 vibrate left and right, the transmission gear 51 drives the regular polygonal insert block 55 to vibrate left and right synchronously.

[0062] When the regular polygonal insert 55 moves close to the rotating column 7, the regular polygonal insert 55 pushes the synchronous rotating seat 82 to move close to the rotating column 7. At this time, the synchronous rotating seat 82 drives the regular polygonal sliding column 8 to insert into the regular polygonal shrinkage groove 71. At this time, the synchronous rotating seat 82 squeezes the reset spring 85.

[0063] When the regular polygonal insert 55 moves away from the rotating column 7, the synchronous rotating seat 82 is pushed away from the rotating column 7 by the elastic force of the return spring 85, so that the synchronous rotating seat 82 can always be sleeved on the regular polygonal insert 55.

[0064] During the left and right movement of the regular polygonal insert 55, the regular polygonal insert 55 is always inserted into the regular polygonal slot 83, so that the synchronous rotating seat 82 can continuously drive the regular polygonal insert 55 to rotate, providing power to the cleaning mechanism.

[0065] Working principle: During assembly, first push the adjusting sleeve 84 to move the synchronous rotating seat 82 closer to the rotating column 7. At the same time, the synchronous rotating seat 82 drives the regular polygonal sliding column 8 to insert into the regular polygonal shrinkage groove 71.

[0066] Next, insert the support plate 2 from front to back between the two docking plates 3, so that the docking grooves 21 at both ends of the support plate 2 fit onto the two docking plates 3. When the docking plate 3 is fully inserted into the docking groove 21, the locking block 34 in the locking mechanism engages with the locking groove 22, so that the docking plate 3 and the docking groove 21 are relatively fixed. The locking mechanism locks the docking plate 3 and the support plate 2, so that the docking plate 3 cannot be separated from the docking groove 21. Then, connect the external water pipe to the connector at the upper end of the water inlet pipe 32, so that the external water pipe can supply water to the water inlet pipe 32.

[0067] At this point, loosen the adjusting sleeve 84. Under the action of the return spring 85, move the synchronous rotating seat 82 closer to the regular polygonal plug 55 until the regular polygonal plug 55 and the regular polygonal slot 83 are fully connected, thus completing the assembly.

[0068] During disassembly, the regular polygonal slot 83 of the synchronous rotating seat 82 is separated from the regular polygonal insert 55. At the same time, the two pull rods 35 are pulled outward along the concave plate 33, so that the end of the locking block 34 is moved out of the locking groove 22. At this time, the support horizontal plate 2 can be moved forward from between the two docking plates 3. The support horizontal plate 2 drives the left and right shaking mechanism and the cleaning mechanism to move out of the protective cover 1, thus completing the disassembly.

[0069] The locking mechanism allows for easy installation and disassembly of the support plate 2, the left and right shaking mechanism, and the cleaning mechanism, facilitating subsequent cleaning, maintenance, or replacement of the equipment and greatly improving work efficiency.

[0070] During operation, the protective cover 1 is connected to the photovoltaic cleaning robot. The photovoltaic cleaning robot and the protective cover 1 are placed on the upper part of the photovoltaic panel to be cleaned. The photovoltaic cleaning robot drives the protective cover 1 to move along the upper part of the photovoltaic panel. At the same time, the external water pipe supplies water to the water inlet pipe 32, and the servo motor is started.

[0071] When the protective cover 1 moves, it drives the cleaning mechanism to move, so that the cleaning mechanism can clean the upper part of the photovoltaic panel; the water inlet pipe 32 sends water into the water inlet tank 23, and the water flows along the water inlet tank 23 into the connecting tank 24 and the through tank 41;

[0072] When water flows into the through groove 41, it sprays downwards along the water outlet 62 located below the through groove 41, thereby rinsing the stains on the upper part of the photovoltaic panel.

[0073] At the same time, the motor shaft of the servo motor drives the rotating column 7 to rotate. The rotating column 7 drives the synchronous rotating seat 82 to rotate synchronously through the regular polygonal sliding column 8. The synchronous rotating seat 82 drives the regular polygonal insert 55 to rotate synchronously. The regular polygonal insert 55 drives the adjacent transmission gear 51 to rotate synchronously. The transmission gear 51 drives the toothed belt 54 to rotate. The transmission gear 51 drives the transmission gear 51 at the other end of the toothed belt 54 to rotate through the toothed belt 54. The two transmission gears 51 inside the toothed belt 54 drive the two round shafts 5 to rotate. At this time, the drive sleeve 52 sleeved on the round shaft 5 rotates synchronously with the round shaft 5.

[0074] When the round shaft 5 rotates, the two transmission gears 51 at both ends rotate synchronously. The two transmission gears 51 at both ends of the round shaft 5 drive the two toothed belts 54 to rotate synchronously. The two toothed belts 54 drive the transmission belt 6 to rotate synchronously. The transmission belt 6 drives the cleaning rod 61 to rotate, so that the cleaning rod 61 can clean the stains on the upper part of the photovoltaic panel.

[0075] When the round shaft 5 rotates, it drives the drive sleeve 52 in the vibration drive assembly to rotate synchronously, causing the drive sleeve 52 to vibrate back and forth along the drive column 57. The drive sleeve 52 drives the vibration sleeve 4 to vibrate synchronously left and right through the round shaft 5 and the positioning block 42. The vibration sleeve 4 drives the toothed belt 54, the transmission belt 6, and the cleaning rod 61 to move back and forth left and right, causing the transmission belt 6 to vibrate left and right while rotating back and forth, so that the cleaning rod 61 can effectively clean the stubborn stains on the upper part of the photovoltaic panel. While the transmission belt 6 vibrates left and right, the water sprayed from the water outlet 62 at the lower end of the transmission belt 6 will also move left and right. Through the cleaning rod 61 and the sprayed water, the cleaning effect on the stains is improved, greatly improving the cleaning effect on the photovoltaic panel.
