Description

Technical Field

[0001] The utility model relates to a cleaning structure, specifically, particularly to a structure for cleaning photovoltaic panels. Background Art

[0002] A photovoltaic panel is a device that converts solar energy into electrical energy. There will be certain stains on the surface of photovoltaic panels after being used or stored for a certain period of time. In order to be able to use it normally, it is necessary to clean the stains on the surface of the photovoltaic panel. The existing cleaning method generally uses an operator to hold a cleaning brush by hand to clean the photovoltaic panel placed on the ground. On the one hand, the labor intensity of the operator is large; on the other hand, a relatively flat cleaning area is required to effectively avoid the problem of directly placing the photovoltaic panel on the ground and shaking; on the other hand, when an operator directly holds a cleaning brush by hand for cleaning, due to different techniques and strengths of each person, it is easy to damage the photovoltaic panel.

[0003] Chinese Patent with the application number CN202120706661.1 provides a patent named a cleaning device for photovoltaic panel maintenance and repair. When cleaning, the lifting beam drives the scraper into the cleaning bin, so that the scraper cleans the photovoltaic panel during the downward movement. It can be seen from this that the cleaning of the photovoltaic panel is completed by the scraper from top to bottom once. If it is not cleaned up at one time, the lifting cylinder needs to drive the scraper to move up and down to clean the photovoltaic panel multiple times. However, on the one hand, this technical solution is provided with components such as telescopic columns, telescopic sleeves, pin shafts and telescopic springs. The above components are used to give an elastic abutting force to the rubber scraper so that the rubber scraper abuts tightly against the photovoltaic panel. However, when the scraper moves upward, since the rubber scraper abuts tightly against the photovoltaic panel and there is no structure for limiting the photovoltaic panel, the movement of the rubber scraper will drive the photovoltaic panel to move upward, and both sides of the photovoltaic panel are in contact with the rubber rollers, making it more likely to drive the photovoltaic panel upward. As the photovoltaic panel moves upward, when the abutting force is insufficient, it will fall downward, thus there is a risk of damaging the photovoltaic panel; on the other hand, this structure involves a relatively large cleaning bin and also involves components such as a lifting cylinder, which not only increases the overall weight and makes it inconvenient to transport, but also because the size of the cleaning bin is limited, it is impossible to clean a larger number of photovoltaic panels at one time according to actual needs.

[0004] Therefore, those skilled in the art are committed to providing a photovoltaic panel cleaning structure that can effectively solve the above technical problems. Summary of the Utility Model

[0041] Notches 21 are provided at the lower ends of both sides of each guiding seat 18. A positioning groove 22 and a positioning member 23 are respectively arranged at each notch 21.

[0046] The optimal working principle of the present utility model is as follows:

[0047] During use, the photovoltaic panel 99 is placed on the positioning frame 3 and limited by the two guiding seats 18 and two limiting platforms 6 of the positioning frame 3. The operator aligns the sliding seats 8 at the lower ends of the two positioning seats 7 with the respective guide rails 5 and inserts them from one end of each guide rail 5 into the guide rail 5 for sliding connection therewith. The operator holds the handle 37 and moves the cleaning unit 2 along the guide rail 5, so that the surface stains of the photovoltaic panel placed on the guide rail 5 can be cleaned by the scraper 10 and the roller 11. Further, before use, according to the actual number of photovoltaic panels to be cleaned and the size of the use site, the positioning units 1 in an appropriate number can be used. The connection steps of every two adjacent positioning units 1 are as follows:

[0048] Two adjacent positioning units 1 are limited by inserting a positioning member 23 into a positioning groove 22. After the positioning member 23 is inserted into the positioning groove 22, the guide rails 5 in the two adjacent positioning units 1 are attached to each other to form an extended track. Due to the mutual connection and limitation of each positioning unit 1, and anti-slip ribs 27 are further provided at the bottom of each positioning unit 1, so that during cleaning, each positioning unit 1 will not move due to the use of the cleaning unit 2. Therefore, during use, it is no longer necessary to position each positioning unit 1 with the ground. The positioning unit 1 can be directly placed on the ground and two adjacent positioning units 1 can be connected. By moving the cleaning unit 2 back and forth to clean the surface stains of the photovoltaic panel, the photovoltaic panel will not shake either;

[0049] When the stains on the surface of the photovoltaic panel are not easy to clean, the operator can use the cleaning liquid on the photovoltaic panel. In order to avoid the cleaning liquid remaining on the photovoltaic panel all the time, when using the cleaning liquid, one side of the positioning unit 1 can be lifted, and then the positioning column 35 can be inserted into the through hole 33 of the support block 32, and at the same time, it is limited by the limiting ring 36. Through the above structure, the positioning unit 1 can be inclined, so that the stains and cleaning liquid on the surface of the photovoltaic panel can flow down quickly.

[0050] When the utility model is in use, it is driven manually, the structure is simpler and the cost is lower. Of course, it is not limited to pure manual operation. According to the actual use situation, a motor can also be installed on the positioning seat 7, and the roller 11 is driven by the motor to rotate to clean the photovoltaic panel. At the same time, the shape of the positioning unit 1 is regular, which is convenient for storage, and the space occupied during transportation is also small.
