Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment operation and maintenance, specifically to a photovoltaic operation and maintenance cleaning device. Background Technology

[0002] Photovoltaic systems convert solar energy into electrical energy and store and transmit it through photovoltaic panels that absorb solar radiation energy when exposed to direct sunlight. Dirt and other pollutants deposited on the surface of the modules can prevent or reduce direct sunlight, negatively impacting the output of the system units. Contamination of solar panels occurs in various ways and forms and is not always visible to the naked eye. Even the thinnest layer of dust and dirt, such as soot and pollen, along with bird droppings and leaves, can significantly impact the performance of photovoltaic systems. Moss and lichen pose a serious risk, attacking the frame and module components. All these impurities present a significant risk to the efficiency of photovoltaic systems. During the operation and maintenance of photovoltaic equipment, the managers often use non-professional tools such as trays, brooms, and brushes to clean these stains. This can lead to various problems, such as difficulty in using the tools and the inability to remove some dirt from the photovoltaic panels. Therefore, a photovoltaic operation and maintenance cleaning device is provided. Utility Model Content

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a photovoltaic operation and maintenance cleaning device, combined with the attached... Figure 1-3 The device includes a handle 1, which has a hollow structure. A brush head 12 for wiping dirt from the surface of the photovoltaic panel is installed at the end of the handle 1. By providing a multifunctional, adjustable, and detachable brush with a handle, it is convenient for personnel to clean dirt, dust, and debris from the surface of the photovoltaic panel during operation and maintenance. The top of the handle 1 is connected to a support 5 that supports the brush head 12. The handle 1 and the support 5 are connected together by a telescopic mechanism that allows the handle 1 to be partially extended. The telescopic mechanism includes a primary electric cylinder 6 installed inside the handle 1 and connected to the support 5 at its moving end. Since photovoltaic panels are often large in size, it is not easy for people to reach certain areas on the photovoltaic panels. By installing an electric telescopic rod, namely a first-stage electric cylinder 6, inside the handle 1, the handle 1 is made to extend and retract. When the handle 1 is extended by the first-stage electric cylinder 6, the brush head 12 installed at the end is further away from the person, making it easier for the person to clean the photovoltaic panel area that is far away from them. The brush head 12 is rotatably mounted on the handle 1. The handle 1 is equipped with a rotary transmission assembly that drives the brush head 12 to rotate and perform deep cleaning of the photovoltaic panel surface. Figure 4 The rotary transmission assembly includes a transmission shaft 2 rotatably connected to the handle 1, a motor 3 installed below the handle 1 that drives and cooperates with the transmission shaft 2, a support shaft 4 with a hollow bottom structure rotatably connected to the support 5, a slider and a groove that fit together are respectively connected to the outer side of the transmission shaft 2 and the inner side of the support shaft 4, the transmission shaft 2 is embedded in the bottom of the support shaft 4, causing the support shaft 4 to rotate synchronously with the transmission shaft 2; The top of the support shaft 4, which is rotatably connected inside the support 5, supports the brush head 12 and the connecting plate 11. The handle 1 is equipped with a battery and a power supply and charging system. When the motor 3 is powered on, it causes the transmission shaft 2 to rotate. Since it needs to cooperate with the extension and retraction function of the handle 1, the original output shaft of the motor 3 is divided into two parts: the transmission shaft 2 and the support shaft 4. The two parts are in contact with each other and can slide against each other to extend and retract. Furthermore, by setting sliders and grooves respectively, they cooperate with each other to maintain synchronous rotation. Combined with appendix Figure 5 A connecting plate 11 is connected to one side above the support 5. The brush head 12 is installed on the connecting plate 11 by bolts, nuts and other fixing components. A swing adjustment mechanism that can adjust the tilt of the brush head 12 on the handle 1 is installed between the support 5 and the connecting plate 11. The swing adjustment mechanism includes a bushing 9 that is rotatably connected to the driven shaft 8. A two-stage electric cylinder 10 is rotatably connected between the support 5 and the bushing 9. Depending on the distance and orientation between the area of ​​the photovoltaic panel being wiped and the standing position of the personnel, the secondary electric cylinder 10 is also an electric telescopic rod by bending the end of the entire handle. It is installed at the handle 1 and the brush head 12 respectively by rotating the two ends. When it extends and retracts, the length changes, causing the brush head 12 to tilt and rotate on the handle 1, changing the position of the brush head 12 on the handle 1, so that the personnel can clean the target area of ​​the photovoltaic panel in a relaxed posture. The rotary transmission assembly also includes a driven shaft 8 rotatably connected above the support 5 and receiving the connecting plate 11 at its end. The support shaft 4 and the driven shaft 8 are each connected to a lifting ring 7 at their close ends. The lifting rings 7 are interlocked together, so that the driven shaft 8 can rotate with the support shaft 4 when it is at any angle above the support 5. To facilitate the function of adjusting the angle of the brush head 12 on the handle 1, the top of the output shaft of the motor 3 is divided into two parts: a support shaft 4 and a driven shaft 8. The two parts are connected to each other by a hanging ring 7, which is not fixed in position. The driven shaft 8 is supported by the bushing 9 and the secondary electric cylinder 10. The bushing 9 and the driven shaft 8, as well as the support 5 and the support shaft 4, are connected by bearings. Thus, the driven shaft 8 can be rotated together with the support shaft 4. Even when the handle is bent, the brush head 12 can still be affected by the motor 3 and continue to rotate.

[0022] In a specific implementation, the cleaning device is a brush with a rod. When retracted, it is not large in size, making it convenient for photovoltaic equipment maintenance personnel to carry with them and clean the surface of the photovoltaic panels during maintenance. Some start / stop buttons are set on the handle 1. When in use, the motor 3 can be started to make the brush head 12 rotate, which makes the cleaning effect more obvious. For example, dried bird droppings, mud and other dirt can be wiped off quickly. The brush head 12 can also be pre-wetted to have a better wiping effect on floating dust. When encountering areas that are too far away to reach, the first-stage electric cylinder 6 extends to extend the brush head 12 further to reach the target area. In areas where it is inconvenient to hold the brush in its straight position, the extension and retraction of the secondary electric cylinder 10 can be used to bend and adjust the brush head 12 to a certain extent, making it easier to hold and clean.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
