Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic fence technology, specifically a photovoltaic fence structure. Background Technology

[0002] Photovoltaic fences are an innovative product that deeply integrates building envelope structures with green energy technologies. They are widely used in public facilities such as roads, parks, and industrial parks. They combine the isolation, protection, enclosure, and aesthetic functions of traditional fences with the attribute of distributed power generation, making them an important part of municipal and green energy infrastructure. Compared with traditional ground-mounted photovoltaic systems, photovoltaic fences do not require the construction of complex support structures and cement foundations. They can directly rely on the fence itself for stable support. At the same time, they can use the internal cavity of the fence or pre-buried pipes to achieve concealed cable laying, which improves the safety and aesthetics of the system while reducing infrastructure construction costs.

[0003] In existing technologies, photovoltaic panels on photovoltaic fences are exposed to the outdoor environment for a long time. Dust, powder and other impurities in the air easily adhere to the surface of the photovoltaic panels. As the usage time goes by, these deposits will gradually form a covering layer, blocking the area of ​​the photovoltaic panels that receive sunlight, resulting in a significant reduction in the light absorption efficiency of the photovoltaic panels, and thus affecting the power generation efficiency of the entire photovoltaic system. To address this issue, we propose a photovoltaic fence structure. Utility Model Content

[0012] Preferably, the working end of the mounting bolt is fitted with a circular rubber film.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model uses a designed rinsing mechanism, a nozzle with a conical head and connecting line to spray water to rinse the photovoltaic panel, thoroughly remove dust from the surface of the photovoltaic panel, avoid blocking sunlight, stabilize light absorption efficiency, and blow out gas from the nozzle after cleaning to dry the photovoltaic panel and pipeline residual moisture, prevent impurities from clogging the nozzle and U-shaped pipe, extend the life of the rinsing mechanism and photovoltaic panel, and reduce maintenance costs.

Detailed Implementation

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 This utility model provides a technical solution: a photovoltaic fence structure, including a fence body, two mounting frames 103 installed on the fence body, and multiple photovoltaic panels 104 installed on the mounting frames 103. The mounting frames 103 are hot-dip galvanized steel pipes with black paint on the surface. A washing mechanism is provided above the fence body. The washing mechanism includes: The U-shaped tube 201 is installed above the mounting bracket 103, and multiple nozzles 202 are fixedly installed at the bottom of the U-shaped tube 201 for cleaning the photovoltaic panel 104. A conical head 203 is provided below the nozzle 202. When the nozzle 202 sprays water or gas downwards, it blows towards the conical head 203. Due to the structural characteristics of the conical head 203, which is small at the top and large at the bottom, the water or gas can spread outwards and in all directions after contacting the bottom, increasing the rinsing or drying effect on the surface of the photovoltaic panel 104. Two connecting lines 204 are fixedly provided between the conical head 203 and the nozzle 202. Through the connecting lines 204, when water or gas rushes towards the conical head 203, the conical head 203 can swing, thereby allowing the water or gas to spread outwards a greater distance and range, further increasing the rinsing or drying effect on the surface of the photovoltaic panel 104. The conical head 203 is used to diffuse the water or gas sprayed from the nozzle 202.

[0018] Example 2 Please refer to Example 1. Figures 1-3 , Figures 5-7A connecting pipe 207 is fixedly installed between the two U-shaped pipes 201. The connecting pipe 207 is a concave structure when viewed from above and can bypass the column 100. Two top frames 200 are fixedly installed between the U-shaped pipes 201 and the mounting frame 103. A fixed pipe 208 is fixedly installed at one end of the U-shaped pipe 201. A side pipe and a water pipe 205 are respectively installed on one side of the fixed pipe 208. A left valve 210 is installed on the side pipe. The water pipe 205 is connected to an external water supply device, and the air pipe 206 is connected to an external air supply device. When the nozzle 202 is ready to spray water, the left valve 210 is opened and the right valve 209 is closed. After rinsing is completed, the right valve 209 is opened and the left valve 210 is closed. At this time, the gas enters the U-shaped pipe 201 and then enters the nozzle 202, and then flows from the nozzle 202 towards... The downward blowing can dry the water on the surface of the conical head 203, connecting wire 204, and photovoltaic panel 104. This prevents external dust and dirt from adhering to the wet surface of the conical head 203, connecting wire 204, and photovoltaic panel 104 when the water is not dry. If these particles form clumps after drying, they may cause blockage of the nozzle 202. Alternatively, dust and dirt on the photovoltaic panel 104, conical head 203, and connecting wire 204 may clump together, affecting sunlight reception or subsequent use. The gas can also clean residual water droplets and impurities inside the U-shaped tube 201 and nozzle 202.

[0019] A gas connection pipe 206 is provided on the other side of the fixed pipe 208, and a right valve 209 is provided on the gas connection pipe 206.

[0020] Example 3 Based on Example 2, please refer to 1- Figure 4 , Figure 6 and Figure 7 A heating element is provided between the connecting pipe and the water pipe 205. The heating element includes a heating box 302 fixed between the water pipe 205 and the side pipe. A heating wire 300 is provided inside the heating box 302. The heating wire 300 is the heating element in the electric water heater. A wiring is provided on the heating wire 300, and the end of the wiring extends to the outside of the heating box 302. A plug 301 is fixedly provided at the end of the wiring. The plug 301 facilitates quick connection with an external power supply device to turn on the power. A support rod is fixedly provided between the heating wire 300 and the heating box 302. The support rod can fix the heating wire 300. When cleaning is performed in low ambient temperatures (such as in winter), plug 301 is connected to a power source, and the heating wire 300 is powered on and heats up, heating the water flowing through the heating box 302. This keeps the sprayed water temperature within a suitable range. This design not only prevents the water in the U-shaped pipe 201 and spray nozzle 202 from freezing and clogging the pipes due to low temperatures, but also improves the cleaning effect. Warm water is more likely to dissolve stubborn impurities on the surface of the photovoltaic panel 104, while preventing the low-temperature water flow from damaging the surface of the photovoltaic panel 104, thus ensuring the normal operation of the photovoltaic wall in low-temperature environments.

[0021] In this embodiment, the wall body includes multiple columns 100 and a cross platform 102 located between two columns 100. Multiple side frames 101 are provided on the side of the mounting frame 103. The side frames 101 are galvanized embedded plates. The side frames 101 are fixedly connected to the columns 100 by expansion bolts 106. The clamps 105 are also fixedly connected to the cross platform 102 by expansion bolts 106. With the frame support of the columns 100 and the cross platform 102, and the reliable connection between the side frames 101 and the columns 100, the mounting frame 103 obtains a stable installation foundation, ensuring that the photovoltaic panels 104 will not shift or fall off due to external loads (such as wind force and vibration) after installation. This improves the mechanical stability and safety performance of the entire photovoltaic wall structure and provides a guarantee for the long-term stable power generation of the photovoltaic panels 104.

[0022] In this embodiment, multiple clamps 105 are provided between the photovoltaic panel 104 and the mounting frame 103, the column 100, and the crossbeam 102. A protective film 108 is provided on the clamp 105. Two mounting bolts 107 are threadedly connected inside the clamp 105. With the setting of multiple clamps 105, the static and dynamic forces generated by the self-weight of the photovoltaic panel 104, wind load (positive wind pressure and negative wind pressure), snow load, and possible accidental impacts (such as human leaning or object impact) can be withstood.

[0023] In this embodiment, a circular adhesive film 109 is sleeved on the working end of the mounting bolt 107. The circular adhesive film 109 contacts the photovoltaic panel 104. The clamp 105 is fixedly connected to the mounting frame 103 and the side frame 101 by screws. There is a protective adhesive film 108 on the bottom of the inner wall of the clamp 105 and a circular adhesive film 109 at the working end of the mounting bolt 107 to protect the photovoltaic panel 104. This can effectively protect the photovoltaic panel 104 and prevent the photovoltaic panel 104 from being squeezed and damaged due to thermal expansion and contraction.

[0024] Working principle and usage process of this utility model: In use, the water pipe 205 is connected to an external water supply device, the left valve 210 is opened, and the right valve 209 is closed. Water flows through the fixed pipe 208 and the U-shaped pipe 201 to distribute to each spray nozzle 202. The conical head 203 below the spray nozzle 202, with the help of the connecting line 204, diffuses the concentrated water flow, evenly rinsing the surface of the photovoltaic panel 104. In winter when the temperature is low, the plug 301 is connected to the power supply, and the heating wire 300 in the heating box 302 heats the water flow to prevent the pipes from freezing and to improve the cleaning effect. After cleaning, the left valve 210 is closed and the right valve 209 is opened. 09. External gas connected to the gas pipe 206 is sprayed out from the nozzle 202 through the same pipeline. The conical head 203 also diffuses the gas, quickly drying the surface of the photovoltaic panel 104 and the inside of the nozzle 202, preventing impurities from clumping and clogging. The connecting pipe 207 between the two U-shaped pipes 201 ensures uniform water distribution. The top frame 200 stably supports the U-shaped pipes 201, ensuring the stable operation of the entire flushing mechanism. Through the synergistic effect of each component, the photovoltaic panel 104 is efficiently cleaned and dried, while ensuring the overall stability and safety of the photovoltaic wall structure, maximizing the power generation efficiency of the photovoltaic panel 104.
