Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of photovoltaic support technology, and more specifically, to a photovoltaic support cleaning robot. Background Technology

[0002] Photovoltaic panels, also known as photovoltaic power generation panels, are power generation devices that directly convert solar radiation energy into electrical energy using the photovoltaic effect of photovoltaic cells. Photovoltaic panels are mainly composed of solar panels, cables, power electronic converters, energy storage devices, mounting brackets, and mounting plates. In addition to the traditional solar power plants and distributed rooftop photovoltaics, photovoltaics can also be applied to a variety of scenarios, such as buildings, agriculture, fisheries, public facilities, and landscape construction. These composite and cross-border models enable photovoltaic projects to achieve clean power generation while taking into account economic development and ecological protection. In existing technologies, the use of photovoltaic panels requires installation in an open-air environment, which causes dust and other debris from the external environment to accumulate on the solar panels, thus affecting the sunlight reaching the solar panels and consequently impacting the efficiency of the solar panels in converting solar energy into electrical energy. Furthermore, it requires workers to regularly clean the dust off the solar panels, increasing labor costs. Therefore, a self-cleaning robot for photovoltaic panels is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above-mentioned defects, embodiments of this disclosure provide a photovoltaic support cleaning robot to solve the technical problem that manual cleaning of dust accumulated on solar panels in the prior art is too labor-intensive and inefficient.

[0004] According to one aspect, at least one embodiment of this disclosure provides a photovoltaic bracket cleaning robot applied to a bracket body. The bracket body is provided with photovoltaic panels and further includes steel tracks, a mounting plate, a rinsing mechanism, a sweeping roller, and a drive connector. Two steel tracks are symmetrically fixed on the bracket body. The mounting plate is movably mounted on the two steel tracks via a magnetic walking mechanism. The rinsing mechanism is mounted on the mounting plate for rinsing dust from the photovoltaic panels. The sweeping roller is rotatably mounted on the mounting plate for cleaning the surface of the photovoltaic panels. The drive connector is mounted on the mounting plate for cooperating with the magnetic walking mechanism to drive the sweeping roller to rotate.

[0005] Preferably, the magnetic walking mechanism includes a drive shaft, a connecting plate, and a drive assembly. Two drive shafts are symmetrically rotatably arranged on the mounting plate, and the two ends of the two drive shafts are respectively rotatably connected to the two connecting plates. The drive assembly is arranged on the two steel rails and is used to drive the mounting plate to move.

[0006] Furthermore, the drive assembly includes support rollers, tracks, permanent magnets, and a drive motor. Both ends of the drive shaft are coaxially and fixedly connected to the support rollers. The tracks are fitted and tensioned on the two support rollers on both sides of the mounting plate. Multiple permanent magnets are fixedly installed on the tracks, and the permanent magnets are magnetically engaged with the steel track. The drive motor is mounted on a connecting plate, and the output end of the drive motor is coaxially and fixedly connected to a drive shaft.

[0007] Furthermore, the showering mechanism includes a water storage tank, a water pump, a water outlet pipe, a shower pipe, and shower nozzles. The water storage tank is fixedly mounted on the mounting plate. The input end of the water pump is connected to the water storage tank through a water inlet pipe. One end of the water outlet pipe is connected to the output end of the water pump. The shower pipe is fixedly mounted on the mounting plate and connected to the other end of the water outlet pipe. Multiple shower nozzles are connected to the shower pipe.

[0008] As a further embodiment of this application, the drive connector includes a connecting shaft, a first gear, a second gear, and a drive gear. The mounting plate has a through groove that mates with the cleaning roller. The connecting shaft is rotatably disposed within the through groove. The first gear is fitted onto the connecting shaft and is coaxially and fixedly connected to the connecting shaft. The mounting plate has a cavity. The second gear is rotatably disposed within the cavity and meshes with the first gear. The drive gear is fitted onto the drive shaft and is coaxially and fixedly connected to the drive shaft, and meshes with the second gear.

[0009] As a further aspect of this application, in order to wash away the dust on the photovoltaic panel along the tilt angle of the photovoltaic panel, a plurality of the shower nozzles are tilted on the shower pipe and facing the photovoltaic panel.

[0010] Based on the aforementioned scheme, in order to further clean the photovoltaic panel by the cleaning roller after the shower head has rinsed the photovoltaic panel, the cleaning roller and the shower head are respectively disposed at both ends of the mounting plate.

[0011] Furthermore, in order to enable the magnetic walking mechanism to tilt the mounting plate and move it above the photovoltaic panel, the steel track is tilted and parallel to the photovoltaic panel, and the mounting plate is positioned above the photovoltaic panel.

[0012] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, through the cooperation of the mounting plate, steel track, shower mechanism and magnetic walking mechanism, the water source in the water storage tank is drawn out by starting the water pump. The water source is transferred to the shower pipe through the water inlet pipe, water pump and water outlet pipe, and then sprayed towards the photovoltaic panel through the shower nozzle. Then the drive motor is started. The output end of the drive motor rotates to drive a drive shaft to rotate. The drive shaft drives two support rollers connected to it to rotate. The two support rollers drive the track drive. The track drives another two support rollers to rotate. During the transmission process, the track moves on the steel track through the magnetic attraction between multiple permanent magnets and the steel track, so that multiple shower nozzles tilt and move to wash the dust on the photovoltaic panel. 2. In this disclosure, by setting up a cleaning roller and a drive connector, the drive motor drives a drive shaft to rotate, and the drive shaft drives the cleaning roller to rotate. In conjunction with the magnetic suction walking mechanism, the cleaning roller moves along the surface of the photovoltaic panel during rotation, and can wipe the surface of the photovoltaic panel after it has been rinsed. This removes the dust from the photovoltaic panel, resulting in high cleaning efficiency and saving manpower. Attached Figure Description

[0022] like Figures 1-6 As shown, it illustrates a photovoltaic bracket cleaning robot in one embodiment of the present disclosure, applied to a bracket body 1, on which photovoltaic panels 2 are provided, and also includes a steel track 3, a mounting plate 4, a spraying mechanism, a sweeping roller 5 and a drive connector. like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, two steel rails 3 are symmetrically fixed on the bracket body 1. The mounting plate 4 is movably mounted on the two steel rails 3 via a magnetic suction walking mechanism. In order for the magnetic suction walking mechanism to drive the mounting plate 4 to tilt and move above the photovoltaic panel 2, the steel rails 3 are tilted and parallel to the photovoltaic panel 2, with the mounting plate 4 positioned above the photovoltaic panel 2. The magnetic suction walking mechanism includes a drive shaft 6, a connecting plate 7, and a drive assembly. Two drive shafts 6 are symmetrically rotatably mounted on the mounting plate 4, with each end of the two drive shafts 6 rotatably connected to the two connecting plates 7. The drive assembly is mounted on the two steel rails 3 and is used to drive the mounting plate 4 to move. The drive assembly includes a support roller 8, a track 9, a permanent magnet 10, and a drive motor 11. Both ends of the drive shaft 6 are coaxially fixedly connected to the support roller 8.

The permanent magnets 10 are magnetically engaged with the steel track 3. The drive motor 11 is mounted on a connecting plate 7. The output end of the drive motor 11 is coaxially fixedly connected to a drive shaft 6. Through the magnetic attraction between the multiple permanent magnets 10 and the steel track 3, the mounting plate 4 is tilted on the steel track 3. When the drive motor 11 is started, the output end of the drive motor 11 rotates, driving the drive shaft 6 to rotate. The drive shaft 6 drives the two support rollers 8 connected to it to rotate. The two support rollers 8 drive the track 9 to drive the transmission. The track 9 drives the other two support rollers 8 to rotate. During the transmission process, the track 9 moves on the steel track 3 through the magnetic attraction between the multiple permanent magnets 10 and the steel track 3. like Figure 2As shown, the rinsing mechanism is mounted on the mounting plate 4 and is used to rinse the dust off the photovoltaic panel 2. The rinsing mechanism includes a water storage tank 12, a water pump 13, a water outlet pipe 23, a rinsing pipe 15, and a rinsing nozzle 16. The water storage tank 12 is fixedly mounted on the mounting plate 4. The input end of the water pump 13 is connected to the water storage tank 12 through the water inlet pipe 14. One end of the water outlet pipe 23 is connected to the output end of the water pump 13. The rinsing pipe 15 is fixedly mounted on the mounting plate 4 by two fixing seats. The other end of the rinsing pipe 15 is connected to the water outlet pipe 23. The rinsing pipe 15 is connected to... There are multiple shower nozzles 16. In order to wash away the dust on the photovoltaic panel 2 along the tilt angle of the photovoltaic panel 2, the multiple shower nozzles 16 are tilted on the shower pipe 15 and facing the photovoltaic panel 2. The water pump 13 is a high-pressure water pump. By starting the water pump 13, the water pump 13 draws water from the water storage tank 12. The water is transferred to the shower pipe 15 through the water inlet pipe 14, the water pump 13, and the water outlet pipe 23, and then sprays the photovoltaic panel 2 through the shower nozzles 16. By cooperating with the magnetic walking mechanism, the multiple shower nozzles 16 tilt and move to wash away the dust on the photovoltaic panel 2. like Figures 3-5 The cleaning roller 5 shown is rotatably mounted on the mounting plate 4 and is used to clean the surface of the photovoltaic panel 2. To allow the photovoltaic panel 2 to be further cleaned by the cleaning roller 5 after being rinsed by the shower head 16, the cleaning roller 5 and the shower head 16 are respectively located at both ends of the mounting plate 4. A drive connector is mounted on the mounting plate 4 and is used to cooperate with the magnetic suction walking mechanism to drive the cleaning roller 5 to rotate. The drive connector includes a connecting shaft 17, a first gear 19, a second gear 20, and a drive gear 22. A through groove 18 is provided on the mounting plate 4 to cooperate with the cleaning roller 5. The connecting shaft 17 is rotatably mounted in the through groove 18. The first gear 19 is fitted onto the connecting shaft 17 and is coaxially and fixedly connected to the connecting shaft 17. A cavity 21 is provided inside the mounting plate 4. The second gear 20 is rotatably disposed in the cavity 21. The second gear 20 meshes with the first gear 19. The drive gear 22 is mounted on the drive shaft 6 and is coaxially and fixedly connected to the drive shaft 6. The drive gear 22 meshes with the second gear 20. The drive shaft 6 is driven to rotate by the drive motor 11. While the drive shaft 6 drives the mounting plate 4 to move, the drive shaft 6 also drives the drive gear 22 to rotate. The drive gear 22 drives the second gear 20 to rotate. The second gear 20 drives the first gear 19 to rotate. The first gear 19 drives the connecting shaft 17 to rotate. The connecting shaft 17 drives the cleaning roller 5 to rotate. In this way, the cleaning roller 5 moves along the surface of the photovoltaic panel 2 during rotation, and can be wiped after the surface of the photovoltaic panel 2 is rinsed. It should be added that the sweeping roller 5 is detachably mounted on the connecting shaft 17 by means of a snap fastener, which makes it easy to replace the sweeping roller 5; Working principle: When cleaning dust on the photovoltaic panel 2, the photovoltaic support cleaning robot starts the water pump 13, which draws water from the water tank 12. The water is transferred to the shower pipe 15 through the inlet pipe 14, the water pump 13, and the outlet pipe 23, and then sprayed onto the photovoltaic panel 2 through the shower nozzles 16. Subsequently, the drive motor 11 is started, and the output of the drive motor 11 rotates a drive shaft 6. This drive shaft 6 drives two connected support rollers 8 to rotate, which in turn drives the track 9. The track 9 then drives two other support rollers 8 to rotate. During the transmission process, the track 9 passes through multiple... The permanent magnet 10 moves on the steel track 3 due to magnetic attraction. In conjunction with the magnetic walking mechanism, multiple spray nozzles 16 tilt and move to wash the dust off the photovoltaic panel 2. At the same time, the drive shaft 6 drives the drive gear 22 to rotate, the drive gear 22 drives the second gear 20 to rotate, the second gear 20 drives the first gear 19 to rotate, the first gear 19 drives the connecting shaft 17 to rotate, and the connecting shaft 17 drives the cleaning roller 5 to rotate. In this way, the cleaning roller 5 moves along the surface of the photovoltaic panel 2 during rotation, and can wipe the surface of the photovoltaic panel 2 after it is sprayed, thus removing the dust off the photovoltaic panel 2.
