Intelligent cleaning device for photovoltaic panels

Technical Field

The utility model relates to the field of photovoltaic panel cleaning equipment, in particular to intelligent photovoltaic panel cleaning equipment.

Background Art

Global energy consumption continues to grow, and photovoltaic power generation occupies an important position in energy strategy due to its advantages such as green, economical, and inexhaustible. However, in the operation of photovoltaic power generation systems, in addition to their own performance, dust and particulate matter in the air will also have a great impact on their power generation efficiency. When these pollutants accumulate on the surface of photovoltaic panels, they will affect the light absorption of photovoltaic panels and reduce their power generation efficiency. Research results show that the more dust there is on the surface of photovoltaic panels, the lower their power generation efficiency. When the dust deposition per unit area of photovoltaic panels increases from 0 g/㎡ to 5 g/㎡, the power generation efficiency of photovoltaic panels decreases from 192.3 W to 147.6 W, a decrease of 23.24%. The results show that in order to ensure the good output performance of photovoltaic panels, in addition to protecting the integrity of the photovoltaic panels themselves, it is also necessary to maintain good surface cleanliness. At present, the cleaning methods of photovoltaic panels are mainly manual cleaning and automatic machine cleaning. The manual cleaning method consumes huge manpower and material resources, and there is a risk of causing damage to photovoltaic panels by trampling, so the automatic machine cleaning method has received more and more attention. The automatic cleaning method of the machine is not only convenient, but also safe and efficient. However, automatic cleaning of the machine is limited by the size of the device, the battery capacity and the method of use. Based on this, the utility model studies the application of photovoltaic panel cleaning equipment, designs the intelligent structure of the photovoltaic panel cleaning device, and proposes an advanced photovoltaic panel intelligent cleaning device, which provides a certain scientific basis and technical support for reducing costs and increasing efficiency of photovoltaic power stations.

The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

Example

As shown in Figures 1-3, an intelligent cleaning device for photovoltaic panels includes a skateboard 1. Small motors 2 are mounted on both ends of the upper surface of the skateboard 1. A rotating rod 3 is fixed on the output end of the small motor 2. The bottom end of the rotating rod 3 passes through the skateboard 1 and is fixed with a brush plate 4 for wiping off debris adhered to the surface of the photovoltaic panel. A water spray pipe 5 is also fixed on the side wall on the back of the skateboard 1 for spraying water on the photovoltaic panel to moisten the debris and facilitate wiping off the debris. Vertical plates 6 are also fixed on both ends of the upper surface of the skateboard 1. Connecting blocks 7 are fixed on the side walls on the front of the vertical plates 6. A hand-held rod 8 is movably connected to the connecting block 7. The hand-held rod 8 can be held with both hands to lift the device onto the photovoltaic panel for easy use. A side plate 9 is fixed at the center of the side wall on the front of the skateboard 1. Universal wheels 10 are fixed at the bottom of the side plate 9 to facilitate the device to be pushed and moved on the photovoltaic panel.

In this embodiment, a battery 11 is also fixed on the skateboard 1, and a controller 12 is fixed on one of the hand-held rods 8. The controller 12 is electrically connected to the battery 11 and the small motor 2, and the two small motors 2 move synchronously to achieve intelligent and mechanized cleaning, which saves time and effort, is convenient and fast, and greatly improves the cleaning speed and efficiency.

In this embodiment, a plurality of spray holes for spraying water downward are provided on the water spray pipe 5, and a water supply pipe 13 extending to the top of the skateboard 1 is also connected at the center of the water spray pipe 5, so as to conveniently connect the water supply to continuously supply high-pressure water to the water spray pipe 5, thereby ensuring that the cleaning water can be sprayed directly onto the photovoltaic panel.

In this embodiment, an inner groove 14 is opened inside the connecting block 7, the interior of the inner groove 14 is a spherical groove, and the end is a cylindrical through groove. A steel ball 15 is fixed to the end of the handle rod 8, and the steel ball 15 is located in the spherical groove, which is convenient for turning the skateboard 1.

In this embodiment, the diameter of the steel ball 15 is smaller than the diameter of the spherical groove and larger than the diameter of the through groove. The diameter of the hand-held rod 8 is smaller than the diameter of the through groove. The two hand-held rods 8 can be used to cooperate with each other to rotate the skateboard 1 to adjust the propulsion direction.

In this embodiment, the bottom of the brush plate 4 is lower than the bottom of the universal wheel 10, and a rubber ring is mounted on the roller of the universal wheel 10 to prevent the universal wheel 10 from making head-on contact with the photovoltaic panel, which is beneficial to protecting the photovoltaic panel.

It should be noted that the skateboard 1 and the hand-held rod 8 are made of hard plastic, which is light in weight and hard in material. The weight of the small motor 2 should be small. First, it can reduce the overall weight of the equipment, making it convenient for personnel to use the hand-held rod 8 to lift the equipment onto the photovoltaic panel. Second, it can also prevent the equipment from damaging the photovoltaic panel.

The principle and advantages of the utility model are as follows: the water supply pipe 13 is connected to the water outlet end of the water supply pump with a sufficiently long hose so that the water supply pump can be used to continuously supply water to the water spray pipe 5, and then the handles at the end of the hand-held rod 8 are held with both hands to lift the skateboard 1 onto the photovoltaic panel. At this time, the universal wheel 10 is supported on the photovoltaic panel, and the bottom of the brush plate 4 is tightly attached to the surface of the photovoltaic panel. Then the water supply pump is turned on to supply high-pressure water to the water spray pipe 5, and the clean water in the water spray pipe 5 is sprayed onto the surface of the photovoltaic panel through the spray hole, and then the two small motors 2 are turned on by the controller 12 to rotate with the brush plate 4 against the surface of the photovoltaic panel. The cleaning water sprayed on the surface of the photovoltaic panel can wet the debris, and the debris can be cleaned up after being wiped by the brush plate 4, and then the skateboard 1 is pushed to move on the photovoltaic panel, so as to comprehensively clean the photovoltaic panel. The photovoltaic panel cleaning equipment adopting this structural design is intelligent and realizes mechanization instead of manual hand-held rags to clean the photovoltaic panel, which saves time and effort, is convenient and fast, and greatly improves the cleaning speed and efficiency, thereby improving practicality.
