Description

Technical Field

[0001] The present invention relates to a cleaning robot, and particularly to an intelligent cleaning robot for solar photovoltaic panels. Background Art

[0002] In recent years, the development of new energy represented by photovoltaic power generation has achieved remarkable results. As a renewable energy source, photovoltaic energy helps to achieve the goal of "carbon neutrality" and has a relatively broad growth space. The actual layout forms of photovoltaic power generation are also diverse, including not only large-scale layout but also solar photovoltaic panels installed on street lamp poles.

[0003] Regardless of the form of the photovoltaic panel, it is exposed to the external wind, sun and rain for a long time, and the surface of the photovoltaic panel is prone to adhesion and accumulation of dust, which affects the power generation efficiency of the photovoltaic panel. In this regard, in the field, there are cleaning tools for automatic cleaning of photovoltaic panels, which are cleaned by washing with water. However, in the way of washing with water, the removal of dust only stays at the stage of expelling from the surface of the photovoltaic glass, and the expelled dust is not captured and fixed, resulting in secondary coverage. Simply put, one side is clean while the other side is dirtier.

[0004] In addition, for the solar photovoltaic panels installed on street lamp poles, due to their height limitations, the existing automatic cleaning tools do not have the ability to independently travel to the position of the high photovoltaic panels for active cleaning and require manual assistance for placement. This violates the original intention of "automatic" and becomes a pseudo-automatic cleaning assisted by manual labor, with low efficiency and not meeting the future development needs. Moreover, the existing cleaning tools have poor anti-slip performance on the surface of photovoltaic panels with a large inclination, and there is a risk of displacement and slipping, let alone being able to do a good job in cleaning. Summary of the Invention

[0005] In order to solve the deficiencies of the above technologies, the present invention provides an intelligent cleaning robot for solar photovoltaic panels.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: it includes a pole-climbing robot and a cleaning robot. The pole-climbing robot climbs on the street lamp pole and carries the cleaning robot adsorbed on the placement and conveying platform on one side to climb or descend together.

[0007] The pole-climbing robot includes at least four main rods that are inserted and engaged with each other to form a quadrilateral. A latch is configured on the main rod to be in limit engagement with the tooth section of the main rod; the main rod is formed with a tooth section and a connecting section, and a through opening for inserting the tooth section is formed in the connecting section; the latch extends into the connecting section, and a tooth body that meshes with the tooth section of the main rod is formed at the free end of the latch extending into the connecting section and near the through opening; when multiple main rods are inserted and engaged with each other, the tooth section of any single main rod is inserted into the through opening of the connecting section of the adjacent main rod.

[0008] A rotating wheel driven by a motor is installed on the connecting section of the main rod, the rotating wheel is close to the tooth section of the main rod and is located in a quadrilateral surrounded by at least four main rods, and a gap for accommodating the street light pole is formed between the four rotating wheels;

[0009] The cleaning robot comprises a body, a suction cup track and a scraper device.

[0010] Furthermore, a support frame is installed on the outer side of the connecting section of one of the main rods, and a sliding block connected in a sliding manner and a supporting rocker arm pulled by the sliding block and extending outward are matched with a hole position on the support frame.

[0011] Furthermore, the free end of the supporting rocker is connected to the placing and conveying platform, and one end of the placing and conveying platform is rotationally matched with the free end of the supporting frame. The rotational cooperation is implemented in a manner that the supporting rocker follows the sliding of the slider and thereby pulls to change the inclination angle of the supporting rocker while changing the inclination angle of the placing and conveying platform.

[0012] Furthermore, the cleaning robot also includes driving wheels arranged on both sides of the body and driven wheels that cooperate with the driving wheels to form a four-wheel structure, and a suction cup track covered with suction cups is commonly sleeved on the driving wheel and the driven wheel on one side.

[0013] The driving wheel is driven by a motor built into the machine body.

[0014] The driven wheel is implemented in a manner that the suction cup track is tensioned together with the driving wheel and follows the driving wheel.

[0015] Furthermore, a dust collection bucket is installed on the upper surface of the body, a dust collection fan driven by a motor is installed in one end of the dust collection bucket, and the other end of the dust collection bucket is connected to a dust collection channel extending downward to above the scraper device.

[0016] Furthermore, the scraping edge of the scraper device is consistent with the lowest horizontal position of the suction cup track, so as to scrape away dust on the photovoltaic panel.

[0017] The present invention discloses an intelligent cleaning robot for solar photovoltaic panels. The robot can adapt to street light poles of different diameters through the adjustment and cooperation of a pole climbing robot, and has strong compatibility. The inclination angle of a placement and conveying platform can be adjusted to match photovoltaic panels of different inclination angles. The placement and conveying platform can carry a cleaning robot adsorbed thereon. The cleaning robot moves by adsorption and crawler drive, and has strong grip and high moving smoothness. The cleaning operation of the cleaning robot includes surface cleaning and auxiliary dust suction cleaning, and has high cleaning efficiency and good cleaning effect.

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0030] As Figure 1-8 Collectively shown, this embodiment relates to an intelligent cleaning robot for solar photovoltaic panels, which includes a pole-climbing robot 10 and a cleaning robot 20. The pole-climbing robot 10 climbs on a street lamp pole and carries the cleaning robot 20 adsorbed on the placement and conveying platform 15 on one side to climb up or down together. That is to say, when it is necessary to clean the photovoltaic panel, the pole-climbing robot 10 carries the cleaning robot 20 to crawl along the street lamp pole together. After crawling to the height position where the photovoltaic panel is located, the cleaning robot 20 crawls from the placement and conveying platform 15 to the photovoltaic panel to perform cleaning operations.

[0031] As Figure 1-3 Collectively shown, the pole-climbing robot 10 includes at least four main body rods 16 that are inserted and engaged with each other to form a quadrilateral. A bolt 11 that is limitedly engaged with the tooth section of the main body rod 16 is arranged on the main body rod 16.

[0032] Preferably, the main body rod 16 is formed with a toothed section and a connecting section. A through opening for inserting the toothed section is provided on the connecting section. The bolt 11 extends into the connecting section, and a tooth body that meshes with the toothed section of the main body rod 16 is formed at the free end of the inner extension of the bolt 11 and near the through opening. The part of the bolt 11 extending into the connecting section provides pressure for the tooth body to mesh with the toothed section of the main body rod 16 through a spring loaded at the convex part of the back surface of the tooth body.

[0033] Further, when multiple main body rods 16 are inserted and meshed with each other, the toothed section of any single main body rod 16 is inserted into the through opening of the connecting section of the adjacent main body rod 16. Therefore, when the toothed section of the main body rod 16 changes its depth position relative to the connecting section, the toothed section pulls and applies force to the tooth body, thereby compressing the spring, generating a displacement space, and realizing the mutual depth positions of two adjacent cooperating main body rods 16.

[0034] In this embodiment, a rotating wheel 17 driven by a motor is installed on the connecting section of the main body rod 16. The rotating wheel 17 is close to the toothed section of the main body rod 16 and is located within a quadrilateral formed by at least four main body rods 16. Then, a gap for accommodating the street lamp pole is jointly formed among the four rotating wheels 17. That is to say, by simultaneously abutting against the four rotating wheels 17, it firmly clings to the street lamp pole and moves simultaneously under the drive of the motor, thereby having the ability to climb or descend. Based on the above structure, by changing the mutual positions of the four main body rods 16, that is, changing the size of the quadrilateral formed by the four main body rods 16 and simultaneously changing the size of the gap among the four rotating wheels 17, it can adapt to street lamps with different diameters, increasing the compatibility of the pole climbing robot 10.

[0035] As Figure 2-3 As commonly shown, a support frame 13 is installed on the outer side of the connecting section of one of the main body rods 16. A slider 12 with a hole position fit for sliding connection and a support rocker 14 that is tractioned by the slider 12 and extends outward are arranged on the support frame 13. The free end of the support rocker 14 is connected to the placement and conveying platform 15. Specifically, it is connected to a connecting groove opened on the placement and conveying platform 15 and forms a rotational cooperation therewith. The other end of the connecting groove of the placement and conveying platform 15 is rotationally mated with the free end of the support frame 13. The rotational cooperation is implemented in such a way that the support rocker 14 follows the sliding of the slider 12, thereby changing the inclination angle of the support rocker 14 and simultaneously changing the inclination angle of the placement and conveying platform 15. Thus, by changing the inclination angle of the placement and conveying platform 15, it can adapt to photovoltaic panels set at different angles, facilitating the cleaning robot 20 to run onto the photovoltaic panel for cleaning.

[0036] As Figure 4-5 As commonly shown, the cleaning robot 20 includes a body 21, a suction cup track 24, and a scraping device 27. A cleaning system, a traveling system, and its circuit are also installed inside the body 21. Its functional block diagram is as Figure 6 shown.

[0037] The cleaning robot 20 also includes driving wheels 22 arranged on both sides of the body 21 and driven wheels 23 that cooperate with the driving wheels 22 to form a four-wheel structure. A suction cup track 24 covered with suction cups is jointly sleeved on the single-sided driving wheel 22 and the driven wheel 23. The driving wheel 22 is driven by a motor built into the body 21, and the driven wheel 23 is implemented in a manner that the suction cup track 24 is tensioned together with the driving wheel 22 and follows the driving wheel 22. In the initial state, the cleaning robot 20 is adsorbed on the placement and conveying platform 15 by the suction cups on the suction cup track 24. When the cleaning robot 20 needs to perform cleaning operations on the photovoltaic panel, it is also adsorbed on the photovoltaic panel by the suction cups on the suction cup track 24, thereby increasing the grip ability and preventing the risk of adverse displacement and slipping, thereby ensuring the cleaning quality. Moreover, the way of moving by gripping the ground with the suction cups will not cause damage to the surface of the photovoltaic panel.

[0038] In this embodiment, a dust bucket 25 is installed on the upper surface of the body 21, and a dust suction fan 26 driven by a motor is installed in one end of the dust bucket 25, and a dust suction channel 28 extending downward to the top of the scraper device 27 is connected to the other end of the dust bucket 25. The scraping blade of the scraper device 27 is consistent with the lowest horizontal position of the suction cup track 24, so as to scrape the dust on the photovoltaic panel. It should be noted that the scraping blade of the scraper device 27 preferably has a hardness lower than that of the photovoltaic panel, and will not scratch the surface of the photovoltaic panel. The scraper device 27 can also carry an electrically driven brush to clean the surface. That is to say, when the cleaning robot 20 moves forward, the scraper device 27 is on the front side of the travel route and scrapes or cleans the dust on the surface of the photovoltaic panel on the front side. At the same time, the dust suction fan 26 works to provide suction for the dust suction channel 28, and the dust suction channel 28 sucks the dust scraped or cleaned by the scraper device 27 into the dust bucket 25, thereby completing the cleaning and dust suction operations at the same time, thereby improving the cleanliness of the photovoltaic panel surface.

[0039] It should also be noted that the cleaning robots 20 can perform multiple cleaning operations in a collaborative manner to improve the cleaning effect.

[0040] The working process of the present invention specifically includes:

[0041] After adjusting to match the thickness of the lamp post, the pole-climbing robot 10 carries the cleaning robot 20 to climb to the location of the photovoltaic panel. The cleaning robot 20 is adsorbed onto the photovoltaic panel and moves horizontally, performing cleaning operations during the movement. When the cleaning robot 20 moves to the end of the photovoltaic panel, the moving system detects the edge position and causes the cleaning robot 20 to turn. When the cleaning robot 20 moves and cleans the other end of the photovoltaic panel, it will return to the placement and conveying platform 15 of the pole-climbing robot 10 under the action of the moving system.

[0042] Thus, the intelligent cleaning robot for solar photovoltaic panels disclosed by the present invention can be adapted to street lamp poles with different diameters through the adjustment and cooperation of the pole-climbing robot 10, and has strong compatibility. The inclination angle of the placement and conveying platform 15 can be adjusted to match photovoltaic panels with different inclination angles. The placement and conveying platform 15 can carry the cleaning robot 20 adsorbed thereon. The cleaning robot 20 travels by adsorption and crawler drive, with strong grip and high traveling smoothness. The cleaning operation of the cleaning robot 20 includes surface cleaning and auxiliary dust suction cleaning, with high cleaning efficiency and good cleaning effect.

[0043] The above embodiments are not limitations to the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention also fall within the protection scope of the present invention.
