Description

Technical Field

[0001] This application relates to the technical field related to the cleaning of photovoltaic panels, and particularly to a cleaning device for photovoltaic panels. Background Art

[0002] The cleaning of photovoltaic panels is an important link to ensure the efficient operation of the photovoltaic system. Debris such as dust, dirt, and bird droppings on the surface of the photovoltaic panels will block sunlight, reduce the absorption of sunlight by the photovoltaic panels, and thus reduce the power generation efficiency. According to research, compared with clean photovoltaic panels, the power generation efficiency of dirty photovoltaic panels may be reduced by 10%-30% or even more. The dirt accumulated over a long period may corrode the glass cover plate on the surface of the photovoltaic panels, affecting its light transmission performance and mechanical strength, and further shortening the service life of the photovoltaic panels. Therefore, a cleaning device is needed to clean the photovoltaic panels.

[0003] In the existing market, when cleaning photovoltaic panels, generally, automated cleaning robots are used. Through preset programs, they automatically clean the photovoltaic panels according to the set time and path. They usually use methods such as brushing and spraying for cleaning. For example, the cleaning device disclosed in the photovoltaic panel cleaning device with the application number 202210092740.7, or a cleaning component may be correspondingly equipped outside each photovoltaic panel to clean the photovoltaic panels.

[0004] However, for the above-mentioned photovoltaic panel cleaning devices, although cleaning by robots reduces manual intervention, it is only suitable for small-scale photovoltaic power stations. For large-scale photovoltaic power stations, cleaning a single photovoltaic panel by a robot at a time will result in a large amount of time consumed in the entire cleaning process, and the cost of the equipment is high. When corresponding cleaning components are set on each photovoltaic panel to quickly complete the cleaning work, it will result in a high cost of the photovoltaic panels. At the same time, the setting of multiple cleaning components will also result in a decrease in the installation quantity of photovoltaic panels within the same area, thereby reducing the power generation. In the existing market, there is also a situation where a cleaning component is installed on a drone to complete the cleaning work. However, when the drone is operating, it requires long-term manual operation to complete the thorough cleaning work. At the same time, it also takes time to control the flight trajectory of the drone to ensure thorough cleaning of the photovoltaic panels. Otherwise, the phenomenon of incomplete cleaning will occur. Summary of the Invention

[0012] Preferably, two groups of limiting rods are symmetrically arranged with respect to the central axis of the rotating roller, and an intermediate plate is integrally installed in the middle of the two groups of limiting rods. The intermediate plate is arranged at a position above the limiting rod. A walking main body is also arranged at the bottom of the limiting rod for assisting the cleaning main body to move flexibly on the photovoltaic panel.

[0013] Preferably, a protruding plate is integrally installed at the top of the limiting rod, and the cross-section of the protruding plate is arranged in an "L" shape, and the highest point of the protruding plate is higher than the highest point of the conveyor belt. A wiping main body is connected to the middle below the conveyor belt for wiping and cleaning the surface of the photovoltaic panel.

[0014] Preferably, the moving main body includes a control motor, a rotating lead screw, a moving sleeve and a fixed cover.

[0019] Compared with the prior art, the beneficial effects of the present application are as follows:

[0020] (1) A mobile cleaning main body is provided, which can be completely stored inside the equipment main body to achieve the effect of complete storage and protection, and will not occupy a large amount of space. When it moves out of the reserved groove, the pulling main body cooperates with the auxiliary setting of the external unmanned aerial vehicle, so that the entire cleaning main body drives the wiping main body to move and clean over a long distance on a batch of photovoltaic modules to be cleaned. Therefore, on the premise of ensuring that the entire device does not occupy a large amount of space, it can also ensure that the entire device quickly performs batch cleaning work. Compared with the robot cleaning on the existing market, the efficiency is higher and the cost is lower. Compared with directly controlling the cleaning component to clean the photovoltaic panel by the unmanned aerial vehicle, it is not necessary to accurately control the movement trajectory of the unmanned aerial vehicle, and it only needs to assist in pushing the cleaning component to slide out, and it does not need to spend time controlling the cleaning component to retract, shortening the operation time of the unmanned aerial vehicle by humans, reducing the burden on the staff, and at the same time, the cleaning efficiency is higher.

[0021] (2) A wiping main body is provided, which is arranged at the bottom of the cleaning main body and can move back and forth along with the back-and-forth movement of the cleaning main body to wipe the surface of the photovoltaic panel back and forth, ensuring that a thorough cleaning work can be completed with a single movement of the cleaning main body, without the phenomenon of incomplete cleaning, and there is no need for secondary cleaning, thus achieving the purpose of reducing the work burden.

[0022] (3) A spraying component is provided, which recovers rainwater through the interior of the equipment main body. With the setting of the high-pressure nozzle at the top of the spraying component, the effect of initially spraying the photovoltaic panel can be achieved. After that, cleaning is carried out, and rainwater can be automatically recovered, which is more environmentally friendly and does not require manual spraying. Therefore, when the photovoltaic panel is in a relatively complex environment such as a mine pit, the entire cleaning equipment can also carry out efficient cleaning work by itself, with less manual intervention and high operation efficiency.

[0038] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be combined arbitrarily to form new embodiments.

[0039] In the description of the present application, it should be noted that for orientation terms, such as the terms "center"; "horizontal"; "longitudinal"; "length"; "width"; "thickness"; "upper"; "lower"; "front"; "rear"; "left"; "right"; "vertical"; "horizontal"; "top"; "bottom"; "inner"; "outer"; "clockwise"; "counterclockwise", etc., the orientation and position relationships indicated are based on the orientation or position relationships shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation; be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0040] It should be noted that the terms "first"; "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0041] A preferred embodiment of the present application is as Figures 1 to 14As shown in the figure, a cleaning device for a photovoltaic panel includes a device main body 1, which is integrally arranged in a rectangular structure. Mounting angle codes are arranged at the bottom of the device main body 1 for installation with the ground. A reserved groove 101 is inlaid inside the top end of the device main body 1;

[0042] A mobile cleaning main body is stored inside the reserved groove 101. The mobile cleaning main body includes a pulling main body 2, a cleaning main body 3, a moving main body 4, and a wiping main body 5. Two groups of the moving main body 4 are symmetrically arranged inside the reserved groove 101, and a moving pulling main body 2 is arranged in the middle of the two groups of the moving main body 4. The top end of the pulling main body 2 is connected to the cleaning main body 3, and a wiping main body 5 is arranged in the middle of the bottom of the cleaning main body 3. A walking main body 6 is arranged at the bottom of the cleaning main body 3 for controlling the cleaning main body 3 to perform active moving work;

[0043] This application provides a cleaning device for a photovoltaic panel. Specifically, when in use, first, according to the different lengths of the photovoltaic panels to be cleaned, different numbers of device main bodies 1 can be selected. After the photovoltaic panels are initially installed, if the installation length of the photovoltaic panels is too long, one device main body 1 needs to be installed on both sides of the photovoltaic panel assembly, so that the device main body 1 is installed with the ground. After the installation is completed, when it is necessary to clean the upper part of the photovoltaic panel assembly, it is necessary to start the moving main body 4 inside the reserved groove 101, so that it drives the cleaning main body 3 and the pulling main body 2 to move outward, and then extends out of the inside of the reserved groove 101. After that, the pulling main body 2 pays out the wire to release the pulling limit on the cleaning main body 3, and then controls the walking main body 6 to work, so that it actively controls the cleaning main body 3 to move on the photovoltaic panel. While moving, the cleaning main body 3 continuously moves back and forth to drive the wiping main body 5 to wipe the surface of the photovoltaic panel, and the effect of cleaning the photovoltaic panel can be achieved;

[0044] Since device main bodies 1 are arranged on both sides of the photovoltaic panel assembly, when the two device main bodies 1 move towards each other at the same time, the effect of quickly cleaning the surface of the equally spaced photovoltaic panel assembly can be achieved;

[0045] To ensure more thorough cleaning, as shown in Figure 12 、 Figure 13 and Figure 14 A hollow structure is arranged inside the device main body 1, and its top end is a mesh structure for the entry of water source. A spraying component 7 is also arranged on the outer wall of the device main body 1 for spraying water;

[0046] The spray assembly 7 includes a water pump 71, a connecting water pipe 72, a high-pressure nozzle 73, and a water inlet pipe 74. The water pump 71 is bolted to the outer wall of the equipment main body 1, and its top penetrates between the connecting water pipe 72 and the water inlet pipe 74 respectively. The water inlet pipe 74 is arranged below the hollow structure inside the equipment main body 1 for pumping water. The connecting water pipe 72 is arranged above the hollow structure inside the equipment main body 1, and its top is connected to the high-pressure nozzle 73. The high-pressure nozzle 73 is arranged at a position slightly above the top of the equipment main body 1;

[0047] When cleaning, it is necessary to start the water pump 71 on the outer wall of the equipment main body 1, so that it sucks the water stored inside the equipment main body 1 through the water inlet pipe 74, and then sucks it into the connecting water pipe 72, and then sprays out from the top of the high-pressure nozzle 73. Thus, the loose dust and dirt attached to the photovoltaic panel can be removed;

[0048] In this application, since the inside of the equipment main body 1 is provided with a hollow structure and its top is provided with a mesh structure, rainwater can be automatically collected, achieving the purpose of making full use of resources and being more energy-saving and environmentally friendly.

[0049] Among them, according to Figure 3 and Figure 4 shown, the pulling main body 2 includes a steel wire cable 21, a winding reel 22, and a dual-axis motor 23. Two groups of winding reels 22 are coaxially connected to both sides of the dual-axis motor 23, and a steel wire cable 21 is wound around the outside of the winding reel 22. The top of the steel wire cable 21 is connected to the cleaning main body 3;

[0050] Specifically, when the cleaning main body 3 is limited and pulled by the pulling main body 2, when it is necessary to release the limit, it is necessary to start the dual-axis motor 23, so that it drives the winding reels 22 on both sides to rotate. When it rotates, it will unwind the steel wire cable 21. Since the top of the steel wire cable 21 is connected to the outside of the cleaning main body 3, the steel wire cable 21 will not pull the cleaning main body 3. Thus, when the external drone device pushes the cleaning main body 3, the cleaning main body 3 will move on the surface of the photovoltaic module, achieving the effect of cleaning the photovoltaic module;

[0051] Subsequently, after the cleaning is completed and the cleaning main body 3 needs to be stored, only need to control the winding reel 22 to rotate in the reverse direction. At this time, it will pull the steel wire cable 21, and thus it will pull the cleaning main body 3 until the cleaning main body 3 is completely moved to the side of the pulling main body 2.

[0052] Furthermore, according to Figure 6 、 Figure 7 、 Figure 8 、Figure 9 , Figure 10 and Figure 11 As shown, the cleaning body 3 includes two groups of rotating rollers 31 and a conveyor belt 34. The conveyor belt 34 is arranged outside the two groups of rotating rollers 31, and the outer sides of the two groups of rotating rollers 31 are connected by a limiting rod 32. The limiting rod 32 and the rotating rollers 31 are connected by a bearing. The top end of one of the rotating rollers 31 is coaxially connected to a driving motor 33, and the driving motor 33 is bolted to the outer side of the limiting rod 32.

[0053] The limiting rods 32 are symmetrically arranged in two groups about the central axis of the rotating roller 31, and an intermediate plate 36 is integrally installed in the middle of the two groups of limiting rods 32. The intermediate plate 36 is arranged at an upper position of the limiting rods 32. A walking body 6 is also arranged at the bottom of the limiting rods 32 to assist the cleaning body 3 in flexibly moving on the photovoltaic panel.

[0054] The top of the limit rod 32 is also integrally mounted with a protruding plate 35, and the cross section of the protruding plate 35 is arranged in an "L"-shaped structure, and the highest point of the protruding plate 35 is higher than the highest point of the conveyor belt 34. A wiping body 5 is connected in the middle below the conveyor belt 34 for wiping and cleaning the surface of the photovoltaic panel;

[0055] Among them, firstly, after the entire cleaning body 3 extends out of the reserved groove 101, the external drone can be controlled to be on the inner side of the protruding plate 35, so the drone is controlled to move outward, which will push the protruding plate 35 to move. Since the protruding plate 35 is connected to the limit rod 32, the rotating roller 31 and the conveyor belt 34 will move together;

[0056] When the cleaning body 3 is moving, it is necessary to start the driving motor 33 to continuously rotate forward and reverse, so that it drives the rotating roller 31 to rotate forward and reverse, and then the conveyor belt 34 continuously drives the wiping body 5 at the bottom to move back and forth. When the wiping body 5 continuously moves back and forth, it will wipe the surface of the photovoltaic panel back and forth, achieving the effect of thorough cleaning.

[0057] When wiping, according to Figure 7 As shown, the wiping body 5 includes a connecting frame 51, a telescopic cylinder 52, a mounting cover 53 and a wiping cotton 54. The connecting frame 51 is arranged at the bottom of the conveyor belt 34, and a telescopic cylinder 52 is arranged inside the connecting frame 51 to connect with the mounting cover 53. The bottom of the mounting cover 53 and the wiping cotton 54 are engaged with each other.

[0058] Specifically, when wiping is required, the telescopic cylinder 52 can be started first to drive the mounting cover 53 to descend, and then the wiping cotton 54 clamped inside it will descend to contact the surface of the photovoltaic panel. After that, with the conveyor belt 34 driving the top of the connecting frame 51 to move back and forth, the wiping cotton 54 will wipe the surface of the photovoltaic panel back and forth, thus completing the wiping and cleaning work;

[0059] Since the top of the connecting frame 51 is provided with a slider that is limited and slides in the chute at the bottom of the middle plate 36, the entire wiping main body 5 can move stably without shaking.

[0060] When storing, according to Figure 2 、 Figure 3 and Figure 4 As shown, the moving main body 4 includes a control motor 41, a rotating lead screw 42, a moving sleeve 43 and a fixed cover 44. The top of the control motor 41 is coaxially connected with the rotating lead screw 42, and the outside of the rotating lead screw 42 is threadedly connected with the moving sleeve 43. The top of the moving sleeve 43 is integrally installed with the fixed cover 44, and the fixed cover 44 is connected to the pulling main body 2 by bearings;

[0061] First of all, the pulling main body 2 is at the topmost position of the moving main body 4, and the outside of the pulling main body 2 is arranged at the edge of the cleaning main body 3. Therefore, at this time, the pulling main body 2 and the cleaning main body 3 are completely clamped inside the reserved groove 101. When cleaning work is required, the control motor 41 needs to be started to drive the rotating lead screw 42 to rotate. When it rotates, it will be threadedly connected with the moving sleeve 43, so that the moving sleeve 43 drives the fixed cover 44 to move outward from the reserved groove 101. Thus, the moving sleeve 43 will drive the pulling main body 2 and the cleaning main body 3 to move outward together. When the cleaning main body 3 is completely moved out, it will be on the surface of the photovoltaic panel. Therefore, through the walking of the walking main body 6 and the auxiliary pushing of the drone, the entire cleaning main body 3 can move a long distance to achieve the cleaning effect.

[0062] In this application, according to Figure 2 and Figure 3 As shown, the pulling main body 2 and the cleaning main body 3 are arranged inside the reserved groove 101 for storage and protection, and the pulling main body 2 and the cleaning main body 3 are moved and extended through the moving main body 4.

[0063] Furthermore, according to Figure 3 As shown, the lowest point of the walking main body 6 is at the same height as the surface of the photovoltaic panel to be cleaned, and a limiting cross plate is arranged at the top of the reserved groove 101 to support and limit the cleaning main body 3;

[0064] The setting of the limiting horizontal plate can ensure that when the cleaning main body 3 moves into the reserved groove 101, its top end will be limited by the limiting horizontal plate, so as to ensure that after it extends out subsequently, it can directly move to the surface of the photovoltaic panel.

[0065] The walking main body 6 includes a driving motor 61, walking wheels 62 and a mounting frame 63. The mounting frame 63 is fixed to the bottom of the limiting rod 32, and a walking wheel 62 is connected to the middle thereof by bearings. The outer side of the walking wheel 62 is coaxially connected to the driving motor 61, and the driving motor 61 is bolted to the outside of the mounting frame 63;

[0066] When the walking main body 6 reaches the top of the surface of the photovoltaic panel, it is necessary to start the driving motor 61 to drive the walking wheels 62 to rotate. Thus, the walking wheels 62 move on the photovoltaic panel, achieving the purpose of driving the limiting rod 32 to move, and thus completing the movement work of the cleaning main body 3.

Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application.
