Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic equipment, and in particular relates to an intelligent cleaning robot for photovoltaic panels. Background Art

[0002] Photovoltaic panels, also known as solar cells, are photoelectric semiconductor sheets that use sunlight to generate electricity directly. As long as the illumination meets certain illumination conditions, it can instantly output voltage and generate current in the presence of a circuit. Solar cells are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect.

[0003] During the actual use of photovoltaic panels, due to long-term exposure to the external environment, a certain amount of dust and impurities often remain on their surface. The presence of impurities will greatly reduce the photoelectric conversion efficiency. Therefore, a cleaning robot is used to regularly clean the photovoltaic panels. The existing cleaning robots cannot flexibly adjust the cleaning angle and cannot be applied to photovoltaic panels in different regions. In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent publication number CN217665269U, which cleans by soaking a cleaning roller in water during use. The dampness of the cleaning roller will increase the adhesion and stickiness of the dust in contact with it. Since the cleaning roller is rolling and in contact with the surface of the photovoltaic panel, the dust will stick to and move on the surface of the photovoltaic panel when the cleaning roller is in contact with the surface of the photovoltaic panel, reducing the cleaning effect. The dust attached to the surface of the cleaning roller requires a large amount of clean water to be rinsed clean, so that the cleaning roller that has not been cleaned clean contacts the photovoltaic panel again, causing the dust to contact and adhere to the photovoltaic panel again, and it cannot be cleaned in a timely and effective manner, increasing the consumption of water resources. Utility Model Content

[0004] The utility model aims to provide an intelligent photovoltaic panel cleaning robot, aiming to solve the technical problem in the prior art that a damp cleaning roller causes increased dust adhesion and reduced cleaning effect when cleaning photovoltaic panels.

[0005] The utility model is implemented as follows: a photovoltaic panel intelligent cleaning robot comprises a base, a cleaning box is arranged on the base and an adjusting component for adjusting the angle and position of the cleaning box is arranged on the base, a fixed tube is fixedly installed in the cleaning box, a coaxially arranged rotating tube is rotatably installed on the fixed tube, the rotating tube is covered with through holes and a plurality of groups of evenly distributed lint cleaning strips are fixedly installed on the outer surface of the rotating tube, a rotating power part for driving the rotating tube to rotate is fixedly installed at one end of the cleaning box, a baffle used in conjunction with the lint cleaning strip is fixedly installed in the cleaning box, and an exhaust fan connected to the cleaning box is fixedly installed on the cleaning box.

[0006] Further technical solution: one end of the fixed pipe extends out of the cleaning box and the other end extending out of the cleaning box extends into the air intake chamber at the end of the cleaning box, a hair dryer with an air outlet end connected to the air intake chamber is fixedly installed at the end of the cleaning box, and the fixed pipe is connected to the jet box.

[0007] Further technical solution: the jet box is located inside the rotating tube and close to the inner wall of the rotating tube, and the jet direction of the jet box is directed toward the inner wall of the rotating tube close to it.

[0008] Further technical solution: both ends of the fixed tube are rotatably mounted with mounting tubes, the mounting tubes are fixedly connected to the rotating tube, one group of mounting tubes is fixedly mounted with a first gear, the first gear is meshed with a second gear fixedly mounted on the output end of the rotating power part.

[0009] Further technical solution: a collecting box is fixedly installed in the cleaning box, the exhaust fan is connected to the collecting box, a baffle is located in the collecting box, and the baffle interferes with the rotation trajectory of the lint cleaning strip.

[0010] Further technical solution: The adjustment component includes a first telescopic part, which is fixedly mounted on the base and drives the top plate to move up and down. A U-shaped mounting frame is rotatably mounted on the top plate and the cleaning box is slidably mounted on the mounting frame. Second telescopic parts that drive the mounting frame to rotate are arranged at both ends of the top plate.

[0011] Further technical solution: A servo module for driving the cleaning box to move is arranged on the mounting frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The surface of the photovoltaic panel is cleaned by a rotating plush cleaning strip, and then the plush cleaning strip collides with the baffle, so that the dust on the plush cleaning strip is detached under the action of the impact, and no water flushing is required, which reduces the consumption of water resources and does not increase the adhesion and stickiness of the dust, thereby achieving timely cleaning of the dust attached to the plush cleaning strip. Then, when the plush cleaning strip contacts the photovoltaic panel again, it is in a clean state, thereby improving the ability of the plush cleaning strip to absorb dust and improving the cleaning effect of the photovoltaic panel.

[0014] 2. The dust on the lint cleaning strip is blown away by high-speed air flow, thereby achieving auxiliary cleaning of the lint cleaning strip. After the dust is blown off the lint cleaning strip, it will move with the air, thereby preventing the dust from flying around at will. The subsequent dust can be drawn out of the cleaning box with the air, thereby improving the dust cleaning effect, facilitating subsequent cleaning, and reducing the residual dust in the cleaning box.

[0015] 3. Air flow can make the lint cleaning strips looser, increase the contact area with the photovoltaic panels, and thus improve the cleaning effect of the photovoltaic panels. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1-Figure 5 As shown, a photovoltaic panel intelligent cleaning robot provided by the utility model comprises a base 1, a cleaning box 7 is arranged on the base 1 and an adjusting component 21 for adjusting the angle and position of the cleaning box 7 is arranged on the base 1, a fixed tube 8 is fixedly installed in the cleaning box 7, a coaxially arranged rotating tube 12 is rotatably installed on the fixed tube 8, the rotating tube 12 is covered with through holes and a plurality of groups of evenly distributed lint cleaning strips 13 are fixedly installed on the outer surface of the rotating tube 12, a rotating power part 16 for driving the rotating tube 12 to rotate is fixedly installed at one end of the cleaning box 7, a baffle 19 used in conjunction with the lint cleaning strip 13 is fixedly installed in the cleaning box 7, and an exhaust fan 20 connected with the cleaning box 7 is fixedly installed on the cleaning box 7.

[0025] In actual application of this embodiment, the base 1 is fixedly installed on the side of the photovoltaic panel so that the cleaning box 7 is located above the photovoltaic panel, and the opening of the cleaning box 7 is adjusted by the adjustment component 21 so that the end face of the cleaning box 7 is parallel to the photovoltaic panel, and then the height of the cleaning box 7 is adjusted so that the end face of the cleaning box 7 is close to the photovoltaic panel and the fluff cleaning strip 13 is in contact with the photovoltaic panel, so that the cleaning box 7 can adapt to the installation height and angle of the photovoltaic panel, thereby improving the flexibility of the cleaning box 7 when adjusted during use. After the adjustment is completed, the rotating tube 12 is driven to rotate by the rotating power part 16, and the rotating tube 12 drives the fluff cleaning strip 13 to rotate, and the rotating fluff cleaning strip 13 cleans the surface of the photovoltaic panel, and then the fluff cleaning strip 13 collides with the baffle 19, thereby Under the action of the impact, the dust on the plush cleaning strip 13 is detached, and there is no need for water flushing, which reduces the consumption of water resources and does not increase the adhesion and stickiness of the dust, so that the dust attached to the plush cleaning strip 13 can be cleaned in time, and then the plush cleaning strip 13 is in a clean state when it contacts the photovoltaic panel again, thereby improving the ability of the plush cleaning strip 13 to absorb dust and improving the cleaning effect of the photovoltaic panel. At the same time, the air in the cleaning box 7 is extracted by the exhaust fan 20, so that the dust falling from the plush cleaning strip 13 is extracted out of the cleaning box 7 along the air, reducing the residual dust in the cleaning box 7, and then reducing the probability of dust falling onto the photovoltaic panel again. By adjusting the component 21 to drive the cleaning box 7 to move along the photovoltaic panel, the surface of the photovoltaic panel can be comprehensively cleaned.

[0026] like Figure 2-Figure 5 As shown, a photovoltaic panel intelligent cleaning robot provided by the utility model, one end of a fixed tube 8 extends out of a cleaning box 7 and the other end extending out of the cleaning box 7 extends into an air inlet chamber 10 located at the end of the cleaning box 7, a hair dryer 11 connected with the air outlet end and the air inlet chamber 10 is fixedly installed at the end of the cleaning box 7, and the fixed tube 8 is connected to a jet box 9.

[0027] Specifically, the jet box 9 is located in the rotating tube 12 and close to the inner wall of the rotating tube 12 , and the jet direction of the jet box 9 is directed to the inner wall of the rotating tube 12 close to it.

[0028] In actual application of this embodiment, the hair dryer 11 conveys air into the air inlet chamber 10, and the air enters the jet box 9 through the pipe, and then the air is sprayed from the jet box 9 to the rotating tube 12, and the air passes through the rotating tube 12 from the through hole on the rotating tube 12 and then blows to the plush cleaning strip 13, so that the dust on the plush cleaning strip 13 is blown away by the high-speed flowing air, thereby realizing auxiliary cleaning of the plush cleaning strip 13, and gathering dust through the collecting box to facilitate subsequent cleaning. After being blown off the plush cleaning strip 13, the dust will move with the air, thereby preventing the dust from flying around at will. The subsequent dust can be drawn out of the cleaning box 7 with the air, thereby improving the dust cleaning effect, facilitating subsequent cleaning, and reducing the dust residue in the cleaning box 7. At the same time, the air flow can make the plush cleaning strip 13 looser, increase the contact area with the photovoltaic panel, thereby improving the cleaning effect of the photovoltaic panel.

[0029] like Figure 5 As shown, a photovoltaic panel intelligent cleaning robot provided by the utility model, both ends of the fixed tube 8 are rotatably installed with mounting tubes 14, the mounting tubes 14 are fixedly connected to the rotating tube 12, and one group of the mounting tubes 14 is fixedly installed with a first gear 15, and the first gear 15 is meshed with a second gear 17 fixedly installed at the output end of the rotating power part 16.

[0030] Specifically, a collecting box 18 is fixedly installed in the cleaning box 7 , the exhaust fan 20 is connected to the collecting box 18 , the baffle 19 is located in the collecting box 18 , and the baffle 19 interferes with the rotation trajectory of the lint cleaning strip 13 .

[0031] In actual application of this embodiment, the rotating power part 16 drives the mounting tube 14 to rotate through the meshing first gear 15 and the second gear 17, and then the mounting tube 14 can drive the rotating tube 12 to rotate, and the rotating tube 12 drives the lint cleaning strip 13 to rotate, and the rotating lint cleaning strip 13 cleans the surface of the photovoltaic panel, and then the lint cleaning strip 13 collides with the baffle 19, so that the dust on the lint cleaning strip 13 is detached under the action of the impact, and the dust attached to the lint cleaning strip 13 is cleaned in time, and then the lint cleaning strip 13 is in a clean state when it contacts the photovoltaic panel again, thereby improving the ability of the lint cleaning strip 13 to absorb dust and improving the cleaning effect of the photovoltaic panel.

[0032] In an example of the present utility model, the rotating power member 16 is a motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor. The motor drives the rotating tube 12 to rotate, thereby achieving the cleaning of the photovoltaic panel.

[0033] like Figure 1 , Figure 2As shown, a photovoltaic panel intelligent cleaning robot provided by the utility model, the adjustment component 21 includes a first telescopic member 2, the first telescopic member 2 is fixedly mounted on the base 1 and drives the top plate 3 to move up and down, a U-shaped mounting frame 4 is rotatably mounted on the top plate 3 and a cleaning box 7 is slidably mounted on the mounting frame 4, and second telescopic members 5 for driving the mounting frame 4 to rotate are arranged at both ends of the top plate 3.

[0034] Specifically, a servo module 6 for driving the cleaning box 7 to move is arranged on the mounting frame 4 .

[0035] In actual application of this embodiment, the second telescopic member 5 drives the mounting frame 4 to rotate, and the rotation of the mounting frame 4 will change the opening direction of the cleaning box 7, and finally make the opening of the cleaning box 7 perpendicular to the surface of the photovoltaic panel. The two groups of laser ranging sensors installed on the end faces of the opening of the cleaning box 7 detect the distance from the end face of the cleaning box 7 to the photovoltaic panel. When the two groups of laser ranging sensors detect that the distances between the photovoltaic panels are consistent, the opening of the cleaning box 7 is perpendicular to the surface of the photovoltaic panel. The height of the top plate 3 is adjusted by the first telescopic member 2, so that the end face of the cleaning box 7 is close to the photovoltaic panel and the fluff cleaning strip 13 is in contact with the photovoltaic panel, so that the height of the cleaning box 7 can adapt to the installation height of the photovoltaic panel. Thereafter, the cleaning box 7 is driven to move along the photovoltaic panel by the servo module 6 to achieve comprehensive cleaning of the surface of the photovoltaic panel.

[0036] In an example of the present utility model, the first telescopic member 2 and the second telescopic member 5 are respectively the first electric telescopic rod and the second electric telescopic rod. Of course, they can also be other components that can actively change the length, such as hydraulic cylinders. The first electric telescopic rod drives the top plate 3 to move up and down to adjust the height of the cleaning box 7. The second electric telescopic rod drives the mounting frame 4 to rotate to adjust the opening direction of the cleaning box 7.
