[0028] Compared with the prior art, the present invention has the following advantages:

[0029] 1. This utility model, by setting up a plug-in structure, enables photovoltaic units to be quickly and easily installed onto the mounting bracket, significantly reducing installation time and labor costs. The plug-in structure allows photovoltaic units to be easily disassembled when maintenance or replacement is required, improving maintenance efficiency and reducing maintenance costs. At the same time, by using a locking structure in conjunction with the plug-in structure, the photovoltaic unit is fixed in place from multiple directions, ensuring that the photovoltaic unit is firmly installed after installation. Even under strong winds, vibrations, or other harsh environmental conditions, the photovoltaic unit is not easy to loosen or fall off, improving the stability and safety of the device.

[0030] 2. Through the sliding connection design of the slide rail and slider, the photovoltaic unit can easily slide along the slide rail and be installed on the crossbar without complicated alignment or fixing operations, further simplifying the installation process. The sliding connection between the slider and the slide rail also allows the photovoltaic unit to be easily slidably removed when maintenance or replacement is required, further reducing maintenance difficulty and time costs.

[0031] 3. The photovoltaic unit is elastically locked towards the column from both sides by the elastic arm and elastic buckle, which makes the installation stable and not easy to loosen. The design of the elastic buckle inserting into the locking slot makes the locking process of the photovoltaic unit simple and quick, without the need for additional tools or complicated operations, which further simplifies the installation process and improves installation efficiency.

[0032] 4. The photovoltaic power generation device of this utility model can include various implementation methods. For example, it can be a power generation device with only a single photovoltaic unit installed on a column, or it can be a power generation device with multiple photovoltaic units installed. The photovoltaic unit can be a single photovoltaic panel located on one side of the column, or two photovoltaic panels located on both sides of the column. Furthermore, several photovoltaic units can be distributed vertically along the axial direction of the column. The photovoltaic panels of the photovoltaic units on the column can be of the same size or different sizes. For example, the size of the lower-layer photovoltaic units can be greater than or equal to the size of the upper-layer photovoltaic units, or the size of the photovoltaic units installed on the column can gradually increase from top to bottom. Each photovoltaic unit has the same output voltage. When the number of photovoltaic units is two or more, the photovoltaic units are connected in parallel to maintain a consistent voltage. This consistent voltage ensures that the photovoltaic module is not affected by weather changes, meaning that each photovoltaic unit, regardless of its individual power output, can be fully utilized and effectively collected, achieving the goal of not wasting electrical energy.

[0033] 5. This utility model also includes a wind turbine to convert wind energy into electrical energy. This device integrates solar and wind power generation functions and can achieve complementary power generation under different weather conditions, thereby improving the continuity and stability of energy utilization. Whether in an environment with sufficient sunlight or strong winds, the device can generate electricity efficiently and reduce energy waste.

[0034] 6. Currently, due to the limitations of existing technology, the efficiency of the back side of a photovoltaic panel is only about 75% of that of the front side. Moreover, the photovoltaic panel receives less sunlight in the morning than in the afternoon, meaning that the effective sunlight exposure time from the east is shorter than that from the west. In this invention, the front side of the photovoltaic unit faces west, and the back side faces east, thereby enabling the photovoltaic unit to generate electricity more effectively.

[0053] The present invention will be further described below with reference to the accompanying drawings:

[0054] As shown in Figures 1 to 17, a photovoltaic power generation device includes a column 1 and a photovoltaic unit 2. The column 1 is provided with a mounting bracket 3 for installing the photovoltaic unit 2. The upper end, lower end, or both ends of the photovoltaic unit 2 are provided with a plug-in structure 4 between the photovoltaic unit 2 and the mounting bracket 3 to plug and fix the photovoltaic unit 2 onto the mounting bracket 3. The column 1 is also provided with a locking structure 5 to lock the photovoltaic unit 2 to the side of the column 1.

[0055] This utility model's photovoltaic power generation device, through the inclusion of a plug-in structure 4, allows the photovoltaic unit 2 to be quickly and easily installed onto the mounting bracket 3, significantly reducing installation time and labor costs. The plug-in structure 4 also enables easy disassembly of the photovoltaic unit 2 for maintenance or replacement, improving maintenance efficiency and reducing costs. Simultaneously, the locking structure 5, in conjunction with the plug-in structure 4, secures the photovoltaic unit from multiple directions, ensuring its stable installation. Even under strong winds, vibrations, or other harsh environmental conditions, the photovoltaic unit 2 is not prone to loosening or falling off, improving the stability and safety of the device. This invention simplifies the installation and maintenance process, reduces labor and equipment costs, and simultaneously improves the lifespan and reliability of the photovoltaic power generation device, exhibiting high economic efficiency and practicality. By optimizing the installation structure, it reduces environmental damage during installation, and as a clean energy source, photovoltaic power generation helps reduce carbon emissions, aligning with sustainable development requirements.

[0056] Further, as shown in Figures 3 and 5, the mounting bracket 3 includes a horizontal bar 31 disposed on the periphery of the column 1, and the insertion structure 4 includes a slide rail 41 disposed on the horizontal bar 31. A connector 100 is fixed to the photovoltaic unit 2, and the connector 100 is provided with a slider 42 that can be inserted into and slide along the slide rail 41. The photovoltaic unit 2 is inserted into the slide rail 41 of the horizontal bar 31 via the slider 42. Through the sliding connection design of the slide rail 41 and the slider 42, the photovoltaic unit 2 can easily slide along the slide rail 41 and be installed on the horizontal bar 31 without complex alignment or fixing operations, further simplifying the installation process. The sliding connection between the slider 42 and the slide rail 41 allows the photovoltaic unit 2 to be easily slidably disassembled when maintenance or replacement is required, further reducing maintenance difficulty and time costs.

[0057] Preferably, the crossbar 31 includes an upper crossbar 311 and a lower crossbar 312 arranged vertically, and the photovoltaic unit 2 is disposed between the upper crossbar 311 and the lower crossbar 312. The upper and lower ends of the photovoltaic unit 2 are fixed to the mounting bracket 3 through the plug-in structure 4, as shown in Figure 1.

[0058] Further, as shown in Figures 3, 4, and 6, a connector 200 is fixed to the side of the photovoltaic unit 2. The locking structure 5 includes at least two or more elastic arms 52 fixed to the side wall of the column 1. The elastic arms 52 are distributed on the front and rear sides of the photovoltaic unit 2. Each elastic arm 52 has an elastic buckle 53 at its end that can be inserted into the locking groove 51 of the connector 200 to elastically lock the photovoltaic unit 2 to the column 1 from both sides. The connector 200 can be integrally set or segmented (not shown in the corresponding figures). The photovoltaic unit is elastically locked towards the column 1 from both sides by the elastic arms and elastic buckles, ensuring a stable installation that is not easily loosened. The design of the elastic buckle 53 inserting into the locking groove 51 makes the locking process of the photovoltaic unit 2 simple and quick, without the need for additional tools or complex operations, further simplifying the installation process and improving installation efficiency. The elastic arms 52 can be connected to the column 1 by threaded fasteners or other connection structures.

[0059] In one embodiment, as shown in Figure 2, a functional box 6 is connected to the top of the column 1. The functional box 6 may be equipped with a light source and / or a disinfection nozzle, thereby enabling the device to perform the functions of a street light or other functions, such as disinfection spraying. An adjustment structure 61 is provided between the functional box 6 and the column 1 to adjust the installation angle of the functional box 6. This facilitates adjustment of the outward extension direction of the functional box, such as the light column, to adapt to different installation environments.

[0060] Furthermore, the top of the column 1 is provided with a mounting plate 300, and the adjustment structure 61 includes a plurality of first mounting holes 611 provided on the mounting plate 300. The functional box 6 is provided with a plurality of second mounting holes 612 that mate with the first mounting holes 611. The second mounting holes 612 are used to mate with different first mounting holes 611 and then be locked with bolts to adjust the installation angle of the functional box 6.

[0061] Among them, column 1 can be cylindrical or a columnar structure with an N-sided cross-section, where N is greater than or equal to 3. Of course, column 1 can also be a multi-faceted pyramidal prism or a conical prism.

[0062] The photovoltaic power generation device of this utility model can include various implementation methods. For example, it can be a power generation device with only a single photovoltaic unit installed on the column 1, or it can be a power generation device with multiple photovoltaic units installed. The photovoltaic unit can be a single photovoltaic panel located on one side of the column 1, or it can be two photovoltaic panels located on both sides of the column 1. Furthermore, several photovoltaic units 2 can be distributed vertically along the axial direction of the column 1. When photovoltaic units 2 are installed both vertically, the lower horizontal bar 312 for installing the upper photovoltaic unit and the upper horizontal bar 311 for installing the lower photovoltaic unit can be integrally installed or separately installed, as shown in Figure 16.

[0063] The photovoltaic panels of the photovoltaic units on the column 1 can be the same or different. For example, the size of the lower photovoltaic unit 2 can be greater than or equal to the size of the upper photovoltaic unit 2, or the size of the photovoltaic unit 2 installed on the column 1 can gradually increase from top to bottom, and the output voltage of each photovoltaic unit 2 photovoltaic panel is the same.

[0064] When there are two or more photovoltaic units 21, they are connected in parallel to maintain a consistent voltage. This consistent voltage ensures that the photovoltaic module 2 is not affected by weather changes; each photovoltaic unit 21, regardless of its power output, can be fully utilized for efficient energy collection and application, thus preventing energy waste. Since winds are stronger at higher altitudes and weaker at lower altitudes, photovoltaic units 21 of different sizes can be installed from top to bottom. When the size of each photovoltaic unit 21 differs, the number of cells inside will also differ. Voltage consistency is achieved by calculating the number of cells connected in series and parallel. For example, assuming each solar cell has a voltage of 0.6V and the total output voltage is 14.4V, and the three photovoltaic units 21 have 48, 72, and 96 solar cells respectively, then in the first photovoltaic unit 21, each circuit has 24 solar cells connected in series and 2 in parallel; in the second photovoltaic unit 21, each circuit has 24 solar cells connected in series and 3 in parallel; and in the third photovoltaic unit 21, each circuit has 24 solar cells connected in series and 3 in parallel. This ensures that the total output voltage of each photovoltaic unit 21 is the same, 14.4V.

[0065] Furthermore, as shown in Figure 1, the column is also equipped with diagonal braces 9 that support the photovoltaic units from below. These diagonal braces 9 can be installed only on the bottommost photovoltaic unit 2, or they can be installed below each photovoltaic unit (not shown in the attached diagram) to make the structure more stable. Alternatively, one or more of the bottommost photovoltaic panels can be replaced with a display screen capable of showing advertisements.

[0066] In one embodiment, the crossbar 31 is equipped with a cleaning nozzle 7 for spraying liquid onto the photovoltaic unit 2 to clean it. The upper crossbar 311 and lower crossbar 312 can be connected to the column 1 via threaded fasteners or welding. The cleaning nozzle 7 can be connected to an air source and a water source via pipelines, and the pipelines control the spraying of water and air via electromagnetic pumps and solenoid valves. Further, the air source can be an air tank or air compressor installed on the column 1, or it can be an external air tank or air compressor. The water source can be a water storage tank installed inside the column 1, or it can be an external water tank or a municipal water supply network.

[0067] Furthermore, the device is also equipped with a control system, which controls the opening and closing of the light source and the cleaning operation. The photovoltaic unit 21 is electrically connected to the control system.

[0068] In one embodiment, a light strip can be added to the frame of the photovoltaic unit 2 to further enhance the aesthetic effect.

[0069] In one embodiment, photovoltaic unit 2 is a double-sided photovoltaic panel. Both the front and back sides of photovoltaic unit 2 can receive sunlight. The front side of photovoltaic unit 2 faces west, and the back side faces east. Currently, due to the limitations of existing technology, the efficiency of the back side of the photovoltaic panel is only about 75% of that of the front side. Moreover, the photovoltaic panel receives less sunlight in the morning than in the afternoon, meaning the effective irradiation time from the east is shorter than the effective irradiation time from the west. In this invention, the front side of the photovoltaic unit, i.e., the front side of the solar cell, faces west, and the back side of photovoltaic unit 2, i.e., the back side of the solar cell, faces east, thereby enabling photovoltaic unit 2 to generate photovoltaic power more effectively.

[0070] In one embodiment, the column 1 is further equipped with a wind turbine 8 for wind power generation. The wind turbine 8 can be the same as or similar to the wind power generation mechanism in patent number CN202411167317.4, entitled "A Wind Power Generation Device and its Wind Power Generation Control Method." Alternatively, the wind turbine 8 can be a conventional wind turbine available on the market. The column 1 is equipped with a battery or external energy storage device for storing electrical energy. This device integrates solar and wind power generation functions, enabling complementary power generation under different weather conditions, thereby improving the continuity and stability of energy utilization. Whether in environments with abundant sunlight or strong winds, the device can generate electricity efficiently, reducing energy waste.

[0071] As shown in Figures 7 to 14, A represents a green belt / pedestrian walkway, C represents a road divider, and B represents a lane. This photovoltaic power generation device can be used as a street light. Figures 7 to 9 show schematic diagrams of the device installed on a north-south oriented road. Figure 7 shows the device installed on a divider between lanes, with the photovoltaic unit 2 facing west and the functional box 6 extending to both lanes, providing illumination through the light source on the box. Figures 8 and 9 show the device installed on a green belt / pedestrian walkway, with the photovoltaic unit 2 facing west and the functional box 6 extending to one side of the lane, providing illumination through the light source on the box. Figures 10 to 14 show schematic diagrams of the device installed on an east-west oriented road. Figure 10 shows the device installed on a divider between lanes, with the photovoltaic unit 2 facing west and the functional box 6 extending to both lanes, providing illumination through the light source on the box. Figures 11 and 12 show the device installed on a green belt / sidewalk. When the column 1 is relatively short, the photovoltaic unit 2 extends only to the side away from the driveway, thus preventing obstruction of the driver's view. The functional box 6 extends towards the driveway side, providing illumination through the light source on the box. Figures 13 and 14 show the device installed on a green belt / sidewalk. When the column 1 is relatively tall, the photovoltaic unit 2 extends in a north-south direction, so that the front of the photovoltaic unit 2 faces west. The functional box 6 extends towards the driveway side, providing illumination through the light source on the box.

[0072] In some embodiments, a plurality of horizontal bars 31 are arranged around the circumference at the same height position of the column 1, and a first tube clamp structure is provided at one end of the plurality of horizontal bars 31 near the column 1 to surround and hold the entire column 1.

[0073] Two crossbars 31 are arranged at the same height position of the column 1 in a circular direction. The first pipe clamp structure includes a first connecting part 1000 arranged on the two crossbars 31 and circumferentially embracing the column 1 from both sides. The first connecting parts 1000 on the two crossbars 31 are respectively provided with a first connecting block 1001 at their respective close ends, and the first connecting blocks 1001 on the two crossbars 31 are connected to each other.

[0074] Two horizontal bars 31 are arranged at the same height position around the circumference so that two sets of photovoltaic units 2 are arranged around the column 1 at the same height position; preferably, the two horizontal bars 31 are evenly arranged around the circumference so that the two sets of photovoltaic units 2 are distributed on both sides of the column 1; of course, only one horizontal bar 31 can be arranged at the same height position around the circumference of the column 1, and the horizontal bar 31 has a tube clamp structure that surrounds and hugs the entire column 1 at the end near the column 1.

[0075] The wind resistance of the device is further enhanced by connecting the uprights 1 through a pipe clamp structure. The first connecting block 1001 between the two crossbars 31 is connected by threaded fasteners, but it can also be connected by other methods such as welding.

[0076] In some embodiments, the photovoltaic unit 2 includes a photovoltaic panel and a frame disposed around the photovoltaic panel, and a reinforcing rod 3000 is fixed between the two side frames of the photovoltaic panel;

[0077] At the same height position, when the photovoltaic unit 2 is only provided on one side of the column 1, the end of the reinforcing rod 3000 near the column 1 is provided with a pipe clamp structure for circumferentially connecting the column 1;

[0078] At the same height, when photovoltaic units 2 are provided on both sides of the column 1, the photovoltaic units 2 on both sides are respectively provided with second connecting parts 2000 that wrap around the column 1 from both sides on the reinforcing rods 3000 on both sides; the second connecting parts 2000 on both sides of the reinforcing rods 3000 are respectively provided with second connecting blocks 2001 at their respective ends that are close to each other, and the second connecting blocks 2001 on both sides of the reinforcing rods 3000 are connected to each other.

[0079] The wind resistance of this device is further enhanced by connecting the uprights 1 using a pipe clamp structure. The second connecting block 2001 between the two reinforcing rods 3000 is connected by threaded fasteners, but other connection methods such as welding can also be used. The reinforcing rods 3000 can be connected to the frame of the photovoltaic panel using threaded fasteners or adhesive bonding.
