Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a drone cleaning device that can be used to clean photovoltaic modules. Background Technology

[0002] In existing technologies, after long-term use, the surface of solar photovoltaic modules easily accumulates a large amount of dust, bird droppings, leaves, and other debris, leading to increased hot spot risk and decreased power generation efficiency. Therefore, timely cleaning and maintenance of solar photovoltaic modules are necessary. However, for photovoltaic modules installed in extreme environments such as high-rise building walls, rooftops, and steep building facades, manual cleaning is difficult and poses safety hazards. Conventional drone cleaning devices are generally only suitable for cleaning curtain walls, high-altitude glass windows, and other scenarios where the installation angle of the objects is relatively fixed. They are not effective for cleaning photovoltaic modules and can easily damage the modules. Utility Model Content

It can be remotely controlled for cleaning operations, ensuring high safety. At the same time, it can achieve efficient cleaning without damaging the surface of the photovoltaic modules, making it more adaptable and providing better cleaning results.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Furthermore, it should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0030] In the description of this utility model, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," etc., may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0031] In the description of this utility model, unless otherwise expressly specified and limited, the first feature "above" or "below" the second feature may include the first feature and the second feature being in direct contact, or the first feature and the second feature not being in direct contact but being in contact through another feature between them.

[0032] See Figures 1 to 3 As shown, this utility model embodiment discloses a drone cleaning device that can be used to clean photovoltaic modules, including a cleaning mechanism 1 and a flight mechanism for driving the cleaning mechanism 1 to fly. The cleaning mechanism 1 includes a cleaning head 11, a detection component 12 for detecting whether the cleaning head 11 is parallel to the surface of the target being cleaned, and an angle adjustment component 13 for adjusting the tilt angle of the cleaning head 11.

[0033] The cleaning device also includes a controller (not shown), which is communicatively connected to the detection component 12 and the angle adjustment component 13. The controller can control the angle adjustment component 13 according to the information fed back by the detection component 12 to adjust the cleaning head 11 to a state parallel to the surface of the target to be cleaned.

[0034] In use, the flight mechanism drives the cleaning mechanism 1 to fly to the vicinity of the cleaning target. The detection component 12 detects in real time whether the cleaning head 11 is parallel to the surface of the cleaning target. The controller receives the information fed back by the detection component 12 and controls the angle adjustment component 13 to adjust the angle of the cleaning head 11 to be parallel to the surface of the cleaning target. Only then is the surface of the cleaning target cleaned by the cleaning head 11.

[0035] In this invention, on the one hand, the flight mechanism and the cleaning mechanism 1 work together to enable the cleaning device to clean photovoltaic modules in extreme scenarios such as the walls, rooftops, and steep building surfaces of high-rise buildings. The cleaning device can be remotely controlled for cleaning operations, ensuring high safety. On the other hand, the cleaning mechanism 1, through the cooperation of the detection component 12, the angle adjustment component 13, and the controller, controls the angle adjustment component 13 based on the information fed back by the detection component 12 before the cleaning head 11 begins cleaning operations. This adjusts the cleaning head 11 to a state parallel to the target surface before cleaning it. This ensures that the cleaning head 11 can adapt to the tilt angle of the target surface during the cleaning process, resulting in higher cleaning capacity and efficiency, and better cleaning effect. At the same time, it avoids problems such as scratching and abrasion of the target surface caused by the mismatch between the tilt angle of the cleaning head and the target surface. When applied to the cleaning of photovoltaic modules, it can achieve efficient cleaning without damaging the surface of the photovoltaic modules, making it more adaptable and providing better cleaning results.

[0036] In some embodiments, see Figure 2 As shown, the cleaning device may also include an integrated control box 3, with the flight mechanism and the cleaning mechanism 1 respectively connected to the integrated control box 3, and the controller located inside the integrated control box 3.

[0037] Understandably, the cleaning device may also include a power supply (not shown), which may be located in the integrated control box 3.

[0038] In some embodiments, the cleaning device may also include a camera (not shown) so that staff can remotely observe the contamination status of the photovoltaic module surface, the working environment, and other conditions in real time.

[0039] Understandably, the cleaning device may also include a remote control terminal (not shown), which is communicatively connected to the controller.

[0040] In some embodiments, see Figure 2 and Figure 3 As shown, the cleaning mechanism 1 includes a base 14, which is connected to the flight mechanism, and an angle adjustment component 13 is disposed between the base 14 and the cleaning head 11.

[0041] The angle of the cleaning head 11 is adjustablely mounted on the base 14 via the angle adjustment component 13.

[0042] In some embodiments, see Figure 1 and Figure 2 As shown, the angle adjustment assembly 13 includes a fixed rod 131 and a movable telescopic rod 132. One end of the fixed rod 131 is fixedly connected to the base 14, and the other end is rotatably connected to the cleaning head 11. Both ends of the movable telescopic rod 132 are rotatably connected to the base 14 and the cleaning head 11, respectively. Specifically, the rotatable connection can be a hinge.

[0043] During angle adjustment, the controller, based on feedback from the detection component 12, controls the extension and retraction of the movable telescopic rod 132, causing the cleaning head 11 to rotate vertically around the connection point between the fixed rod 131 and the cleaning head 11. This changes the tilt angle of the cleaning head 11 relative to the horizontal plane, thereby adjusting the cleaning head 11 to a state parallel to the target surface being cleaned. Compared to adjustment structures using two telescopic components, the angle adjustment component 13 of this cleaning device has a simpler structure and control.

[0044] In some embodiments, the movable telescopic rod 132 may be any one of an electric push rod, a hydraulic push rod, or a cylinder, but is not limited thereto.

[0045] Understandably, an ear can be provided on the side of the base 14 opposite to the cleaning head 11 for connection with the fixed rod 131 and the movable telescopic rod 132.

[0046] In some embodiments, see Figure 2 , Figure 3 and Figure 5 As shown, a liquid supply assembly 15 is provided between the base 14 and the cleaning head 11. An angle adjustment assembly 13 is located outside the liquid supply assembly 15. The cleaning head 11 is provided with a spray nozzle 111. The liquid supply assembly 15 includes a liquid supply container 151 and a pump body 152 for conveying the liquid in the liquid supply container 151 to the spray nozzle 111.

[0047] Understandably, a delivery pipeline (not shown) can be provided between the liquid supply container 151 and the spray nozzle 111, with the pump body 152 located on the delivery pipeline. The inlet of the delivery pipeline is connected to the outlet of the liquid supply container 151, and the outlet of the delivery pipeline is connected to the spray nozzle 111.

[0048] In the cleaning device of this embodiment, the liquid supply component 15 and the angle adjustment component 13 are integrated between the base 14 and the cleaning head 11, resulting in a more compact overall structure. During use, after adjusting the cleaning head 11 to be parallel to the target surface, the liquid in the liquid supply container 151 is sprayed onto the target surface through the spray nozzle 111 under the action of the pump body 152. A liquid spray cleaning method can be used, or a cleaning method combining liquid spraying with mechanical brushing (which can be performed using the brush plate 112 described below) can be used to achieve a better cleaning effect.

[0049] Understandably, the liquid supply container 151 may store clean water or cleaning fluid as needed. For example, the liquid supply container 151 may include a first cavity for storing cleaning fluid and / or a second cavity for storing clean water.

[0050] In some embodiments, see Figure 1 and Figure 2 As shown, the detection component 12 includes a plurality of distance sensors 121, which are located around the periphery of the cleaning head 11.

[0051] Multiple distance sensors 121 measure the distance between different positions of the cleaning head 11 and the surface of the target being cleaned. The controller receives and compares the data collected by each distance sensor 121. If the measured distances at each point are equal or the difference is within a preset threshold range, then the points can be determined to be parallel.

[0052] Understandably, the detection component 12 may include two, three, four or even more distance sensors 121. Preferably, each distance sensor 121 is evenly distributed around the perimeter of the cleaning head 11.

[0053] In some embodiments, the distance sensor 121 includes any one or more of a laser rangefinder, an ultrasonic sensor, and an infrared rangefinder.

[0054] In some embodiments, see Figure 3 and Figure 4 As shown, the cleaning head 11 includes a brush 112 and a rotating power component 113 for driving the brush 112 to rotate.

[0055] In use, after adjusting the cleaning head 11 to be parallel to the surface to be cleaned, the liquid in the liquid supply container 151 is sprayed onto the surface to be cleaned through the spray nozzle 111 under the action of the pump body 152. The rotating power component 113 drives the brush plate 112 to rotate and perform cleaning operations. The mechanical brushing by rotating the brush plate 112 further improves the cleaning effect. By using the cleaning method of spraying liquid in combination with mechanical brushing, efficient cleaning can be achieved while reducing damage to the surface of photovoltaic modules.

[0056] In some embodiments, the brush plate 112 is provided with a bristle brush or a sponge brush, but is not limited thereto.

[0057] In some embodiments, the brush plate 112 is provided with a through hole, through which the liquid sprayed from the spray nozzle 111 can be sprayed out.

[0058] In some embodiments, see Figures 3 to 5 As shown, the cleaning head 11 includes a cleaning seat 114, which has a dust suction port 1143 located around the brush plate 112. The cleaning seat 114 also has a dust suction assembly 16, which includes a dust collection container 161 and an airflow generator 162 for driving airflow from the dust suction port 1143 to the dust collection container 161. The dust collection container 161 is connected to the dust suction port 1143 and the airflow generator 162 respectively.

[0059] Understandably, the airflow generator 162 can be a fan. The airflow generator 162 generates negative pressure, which drives the airflow from the dust inlet 1143 to the dust collection container 161, thereby sucking dust, debris and other impurities into the dust collection container 161.

[0060] The vacuuming function is achieved through the cooperation between the vacuuming component 16 and the cleaning head 11. The cleaning device in this embodiment achieves multiple cleaning functions such as vacuuming, liquid spraying, and mechanical brushing through the cooperation between components such as the liquid supply component 15, the vacuuming component 16, and the brush disc 112 driven by the rotating power component 113. It can meet the cleaning needs of different scenarios, stain types and surface characteristics, and has higher flexibility and better cleaning effect. Moreover, the overall structure is simple, the layout is compact, and the device has a high degree of integration.

[0061] Understandably, in some embodiments, see Figure 6 As shown, the vacuum assembly 16 and the vacuum port 1143 may not be provided.

[0062] In some embodiments, see Figure 3 and Figure 4 As shown, the brush plate 112 protrudes at least partially from the surface where the suction port 1143 is located, to ensure that both the brush plate 112 and the suction port 1143 can operate normally.

[0063] In some embodiments, see Figures 3 to 5 As shown, the cleaning seat 114 includes a main body 1141 and a rotating power component 113 including a rotary motor. The rotating shaft of the rotary motor passes through the main body 1141 and is connected to the brush plate 112. The main body 1141 has an annular dust suction channel 1142 around its perimeter. The annular dust suction channel 1142 has a dust suction outlet for communicating with the dust collection container 161. The annular dust suction channel 1142 extends outward in a direction away from the flight mechanism to form a dust suction port 1143.

[0064] When vacuuming, the airflow generator 162 is activated, and dust, debris and other impurities are sucked into the dust collection container 161 through the suction port 1143 and the annular suction channel 1142.

[0065] The vacuuming assembly 16, the brush 112 driven by the rotating power component 113, and other components are more compactly arranged, and the device has a higher degree of integration.
