Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic maintenance, and particularly relates to a photovoltaic panel cleaning machine. Background Art

[0002] With the increasing popularity of solar power generation, the necessity of cleaning photovoltaic panels has become more and more prominent. The purpose of cleaning photovoltaic panels is to improve the light absorption rate and conversion efficiency of solar cells and ensure the efficient operation of photovoltaic panels. After a period of use of photovoltaic panels, various dirt such as dust, ash, and bird droppings are likely to be deposited on the panels. These dirt will block the incidence of sunlight, resulting in a further decrease in the light absorption rate of solar cells and affecting the power generation efficiency and stability of the entire photovoltaic power generation system.

[0003] The benefits of regularly cleaning photovoltaic panels are mainly in two aspects: one is to maintain the output power of the photovoltaic power generation system and ensure the long-term stable operation of the photovoltaic power generation system; the other is to extend the service life of photovoltaic panels and reduce the maintenance and replacement costs of photovoltaic panels. After photovoltaic cleaning and maintenance, not only will the output power of the photovoltaic power generation system be improved, but also the operation cost and maintenance cost can be reduced.

[0004] At present, the more traditional cleaning method is to use manual labor to clean the surface of photovoltaic panels with all kinds of mechanized cleaning tools (such as mops, rags, disc-shaped automatic cleaning brushes, etc.). This kind of method often requires a large amount of manual labor, and because the cleaning width of the tools is relatively small, therefore, repeated manual movement is required to achieve comprehensive cleaning, and the cleaning efficiency is relatively low. In addition, some cleaning is also carried out by fully automatic cleaning machines or cleaning vehicles. Firstly, because such products have not been popularized in the market yet, their own structural design is relatively complex and the use cost is relatively high. At the same time, fully automatic cleaning machines also need to be equipped with special photovoltaic brackets for use. Therefore, their use is relatively restricted. Especially for large areas of photovoltaic panels arranged in an inclined plane, most of them are cleaned manually.

[0005] Based on this, it is necessary to develop a cleaning machine that can reduce the degree of manual participation and clean efficiently. Summary of the Utility Model

[0025] The principles and features of the present utility model will be described below with reference to the drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0026] Embodiment: As Figure 1 and 2 shown, the photovoltaic panel cleaning machine of this embodiment includes a mobile carrier 1, a column 2, a lifting mechanism 3, a long-strip handrail frame 4, a cleaning pipe 5 and a water tank 6. The above-mentioned column 2 is vertically arranged at the upper end of the above-mentioned mobile carrier 1, and a first power source is provided therein. The above-mentioned water tank 6 is installed at the upper end of the above-mentioned mobile carrier 1. The above-mentioned lifting mechanism 3 is installed on one side of the above-mentioned column 2 and is connected with a mounting frame. One end of the above-mentioned handrail frame 4 is connected with the above-mentioned mounting frame and can be turned up and down on one side of the above-mentioned column 2. The above-mentioned cleaning pipe 5 is installed along the length direction on the side of the above-mentioned handrail frame 4 close to the above-mentioned column 2. A water pump connected to the above-mentioned first power source is provided in the above-mentioned water tank 6. The water pump is connected to the above-mentioned cleaning pipe 5 through a pipeline. Nozzles 61 are provided along the length direction on one side of the above-mentioned cleaning pipe 5.

[0027] In the normal state (not in use) of the photovoltaic panel cleaning machine of this embodiment, the lifting mechanism 3 rises to the high position, and the handrail frame 4 naturally hangs down on one side of the column 2. When in use, taking the cleaning of the inclined photovoltaic panel as an example, the mobile carrier 1 moves to one end of the photovoltaic panel and waits. Then, the handrail frame 4 is manually operated to lift the other end, and the whole handrail frame 4 is in an inclined state, and it is ensured that its height is higher than the surface height of the photovoltaic panel (designated as B in the figure). At this time, the mobile carrier 1 is located on the higher side at one end of the photovoltaic panel, and the operator lifts the other end of the handrail frame 4 and is located on the lower side of the photovoltaic panel. As the mobile carrier 1 and the operator walk in cooperation, the handrail frame 4 is translated to the surface at one end of the photovoltaic panel. Next, the lifting angle of the handrail frame 4 is finely adjusted so that the handrail frame 4 is close to the photovoltaic panel (at this time, the cleaning pipe 5 straddles the width direction of the photovoltaic panel surface). The mobile carrier 1 walks along the length of the photovoltaic panel, and the operator follows. Synchronously, the water pump is turned on, and multiple nozzles 61 spray high-pressure water, and the photovoltaic panel can be effectively cleaned as it walks. During the whole process, two operators can be used, one on the side of the mobile carrier 1 and one on the side where the other end of the handrail frame 4 is located. By cooperating with the walking of the mobile carrier 1, the effective cleaning of the photovoltaic panel can be achieved. The overall structure of the cleaning machine is simple and reasonable, easy to operate and use, can reduce labor costs, and has a relatively high cleaning efficiency.

[0028] In this embodiment, the above-mentioned mobile carrier 1 adopts a tracked robot (which is prior art and will not be elaborated here), and it can be manually controlled by the controller to move, and the operation is relatively convenient.

[0029] In this embodiment, the above-mentioned lifting mechanism 3 includes an electric linear module, and the above-mentioned lifting mechanism 3 is connected to the above-mentioned first power supply. Of course, the lifting mechanism 3 can also adopt a screw transmission pair (a product of the prior art, which will not be elaborated here).

[0030] In this embodiment, as Figure 3 shown, the above-mentioned handrail frame 4 includes two connecting beams 41. The two above-mentioned connecting beams 41 are arranged in parallel at intervals, and a plurality of connecting rods 42 are vertically connected between both ends of the two. One end of the above-mentioned connecting beam 41 is rotationally connected to the above-mentioned mounting frame through a rotating shaft. The structure design of the handrail frame 4 is relatively simple, and there is also enough space to install the cleaning pipe 5.

[0031] In this embodiment, handles 43 are respectively provided at the other ends of the two above-mentioned connecting beams 41. The design of the handles 43 facilitates manual grasping to lift the handrail frame 4. The handles 43 can be connected to the other end of the handrail frame 4 by an articulated structure, mainly to facilitate the operator to hold it to assist in lifting the handrail frame 4 and maintaining stability during walking.

[0032] As a preferred implementation manner, as Figure 1 、 2As shown in Figure 3, it also includes a cleaning brush assembly 7, which includes a long outer shell 71, a roller brush shaft 72, and a rotation drive mechanism 73. The outer shell 71 is installed on one side of the handrail frame 4 along its length direction, and the outer shell 71 is open on one side close to the column 2. The roller brush shaft 72 is rotatably installed between the two ends inside the outer shell 71. The rotation drive mechanism 73 is installed on the other end of the handrail frame 4 and is transmission-connected with the other end of the roller brush shaft 72. A second power supply is provided at the other end of the handrail frame 4, and the second power supply is connected to the rotation drive mechanism 73. The roller brush shaft 72 is provided with bristles partially exposed to the open side of the outer shell 71 (represented by A in the figure).

[0033] In the above embodiment, during the cleaning process, the rotary drive mechanism 73 drives the roller brush shaft 72 to rotate, so that the bristles contacting the surface of the photovoltaic panel rotate to sweep and brush. During the mobile cleaning process, the front of the walking direction is flushed by the nozzle 61, and the back is cleaned with the sweeping brush, and the cleaning effect is better.

[0034] In this embodiment, the rotary drive mechanism 73 includes a motor 731, two pulleys 732 and a belt 733. The other end of the roller brush shaft 72 passes through the other end of the housing 71. The motor 731 is mounted on the other end of the other side of the handrail frame 4. The two pulleys 732 are coaxially mounted on the main shaft of the motor 731 and the other end of the roller brush shaft 72. The belt 733 surrounds the two pulleys 732. The motor 731 is connected to the second power supply. The motor 731 can effectively rotate the roller brush shaft 72 through the combination of the pulley 732 and the belt 733, thereby realizing the effective cleaning of the photovoltaic panel surface by the bristles. The structure design is simple, the power transmission is stable, and at the same time, there will be no position conflict with the cleaning side, and the layout is relatively reasonable.

[0035] In this embodiment, a photovoltaic power generation device connected to the second power source is provided on the other side of the handrail 4. The photovoltaic power generation device can supply power to the second power source, and when cleaning in sunny weather, light-to-electricity conversion can be performed in real time, thereby improving the endurance of the second power source and allowing for a longer cleaning time.

[0036] In this embodiment, two cleaning pipes 5 are provided, and are respectively arranged on both sides of the cleaning brush assembly 7. This layout is relatively reasonable, a cleaning pipe 5 is arranged in the front of the walking direction to cooperate with the nozzle 61 thereon for flushing, the roller brush shaft 72 drives the bristles to be brushed in the middle, and another cleaning pipe 5 is equipped with a nozzle 61 for flushing at the rear, forming a flushing-brushing-flushing combination cleaning method, and the cleaning effect is very good.

[0037] In this embodiment, auxiliary wheels 44 are rotatably provided at both ends of one side of the armrest frame 4. During use, the armrest frame 4 is placed on the upper surface of the photovoltaic panel, and the two auxiliary wheels 44 support on the upper surface of the photovoltaic panel at both ends of the armrest frame 4 respectively. As the mobile carrier 1 moves forward, the auxiliary wheels 44 roll on the surface of the photovoltaic panel, facilitating the mobile cleaning of the entire armrest frame 4 and the machine.
