Description

Technical Field

[0001] The invention relates to the field of building integrated photovoltaic systems, and in particular to a flexible photovoltaic material integrated awning device. Background Art

[0002] As an innovative product that integrates photovoltaic power generation and sunshade functions, photovoltaic awnings have received extensive attention and application in the fields of green buildings, urban public facilities, etc. in recent years. By combining photovoltaic panels with awning structures, it can convert solar energy into electrical energy while providing sunshade effects, providing green and renewable energy supply for buildings or facilities.

[0003] Photovoltaic materials used in photovoltaic awnings are usually high-efficiency solar panels, such as silicon-based solar cells or thin-film solar cells. These materials have excellent photoelectric conversion performance and can directly convert sunlight into electrical energy. Awning materials need to have good sunshade performance, durability and aesthetics. Common awning materials include high-transmittance, low-reflectivity fabrics or specially treated glass. These materials can not only effectively block direct sunlight, but also keep the indoor light soft and the field of vision wide.

[0004] However, traditional photovoltaic awnings also have some shortcomings. First, the cleaning and maintenance of photovoltaic panels is a difficult problem. Since photovoltaic panels are exposed to the outdoor environment, dust and dirt are easily accumulated after long-term use, affecting the photoelectric conversion efficiency. Traditional cleaning methods are often time-consuming and labor-intensive, and it is difficult to achieve the desired effect. Secondly, the balance between shading and power generation requires the layout and angle of photovoltaic panels to be carefully designed to ensure that sufficient shading effect can be provided while maximizing the capture of solar energy for power generation. In practical applications, this balance is often difficult to determine, resulting in poor shading effect or reduced power generation efficiency. In addition, the manufacturing cost of photovoltaic awnings is also relatively high. The procurement and installation costs of photovoltaic panels, awning materials, control systems and other components are high, which to a certain extent limits the popularity and application scope of photovoltaic awnings.

[0025] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0026] (1) The flexible photovoltaic material integrated awning device of the present invention realizes the dual functions of sunshade and power generation by providing an arc-shaped awning, a flexible photovoltaic panel unit arranged on the awning, a cleaning module arranged on one side of the awning, a retractable and deployable module arranged on both sides of the awning, and a control unit arranged on a bracket, effectively combining the sunshade function with the photovoltaic power generation function, and providing a more ideal energy-saving, environmentally friendly, efficient and convenient sunshade and power generation solution for buildings, outdoor facilities and other fields.

[0027] (2) The present invention can remove dust, dirt, bird droppings and other impurities attached to the surface of the flexible photovoltaic panel by means of a cleaning unit and a winding unit arranged on one side of the canopy, and an unfolding unit arranged on the other side of the canopy, effectively preventing dirt from blocking the surface of the photovoltaic panel. At the same time, the flexible photovoltaic panel can be stored by means of automatic winding and unfolding functions to avoid exposure to harsh environments and reduce the accumulation of pollutants on the surface of the flexible photovoltaic panel. The coordinated work of the cleaning unit, the winding unit and the unfolding unit provides the flexible photovoltaic panel with the dual functions of cleaning and protecting, effectively preventing dirt from blocking the flexible photovoltaic panel and causing a hot spot effect, and prolonging the service life of the flexible photovoltaic panel.

[0028] (3) The present invention sets a shading layer on the back of the canopy, sets an isolation layer on the back of the flexible photovoltaic panel, and sets a thermal isolation layer between the flexible photovoltaic panel and the canopy. The shading layer is made of aluminum-plated polyester film, which has high reflectivity and can effectively reflect sunlight, reduce heat transfer downward, and allow heat to dissipate upward; the isolation layer uses thermal conductive silicone pads, thermal conductive gel or graphene and other materials, which can effectively dissipate the heat reflected by the shading layer and prevent heat from being transferred upward; the thermal isolation layer prevents the photovoltaic panel from directly clinging to the canopy by setting a gap, while allowing air to circulate and dissipate heat. Through the cooperation of the shading layer, the isolation layer and the thermal isolation layer, the shading effect of the awning device is effectively improved.

[0029] (4) The present invention sets two layers of vertically arranged flexible photovoltaic panel units on the canopy, which can receive sunlight from different angles. In particular, in the morning and evening when the sun is at a low altitude, the upper photovoltaic panel will not completely block the lower photovoltaic panel, so that both layers can receive sunlight. In addition, when one layer of flexible photovoltaic panels is temporarily rolled up due to failure or maintenance, the other layer of flexible photovoltaic panels can still operate normally, ensuring the sunshade effect and power generation function.

[0046] In addition, the awning device of the present invention is also widely used in urban public facilities, such as bus stops, parks and squares, to provide shade and heat relief for waiting passengers, improve the comfort and humanization level of public transportation services, and enhance the environmental image of the public environment by demonstrating the application of clean energy.

[0047] Example 1

[0048] like Figures 1 to 4 As shown, this embodiment provides a flexible photovoltaic material integrated awning device, including: an awning body 1, a flexible photovoltaic panel unit 2, a cleaning module 3, a retractable module 4 and a control unit 5.

[0049] The awning body 1 comprises an arc-shaped canopy roof 11 and a bracket 12, and the canopy roof 11 is mounted on the bracket 12. A set of guide rails 13 are mounted on the top surface of the canopy roof 11 along the arc direction, and the arc of each guide rail 13 matches the arc of the canopy roof 11, and a flexible photovoltaic panel unit 2 is mounted between every two guide rails 13. The arc-shaped canopy roof 11 provides a sunshade area, which can well block direct sunlight.

[0050] The flexible photovoltaic panel unit 2 includes a wire frame 21, a flexible photovoltaic panel 22 and a slider 23. The wire frame 21 is a two-layer arc frame structure, and a cavity is formed between the two layers of the arc frame to accommodate the flexible photovoltaic panel 22. The flexible photovoltaic panel 22 is a sheet structure, which can be bent according to the curvature of the canopy 11, ensuring the sunshade effect without affecting the power generation performance of the photovoltaic panel. Sliders 23 are installed on both sides of the wire frame 21, and the sliders 23 are slidably arranged in the guide rails 13, allowing the sliders 23 to slide along the curvature direction of the canopy 11 with the wire frame 21 and the flexible photovoltaic panel 22.

[0051] The cleaning module 3 includes a cleaning unit 30, a connection unit 31 and a power unit 32. The head end of the connection unit 31 is fitted and fixed with the end of the guide rail 13, and the connection unit 31 has a cavity inside to allow the flexible photovoltaic panel unit 2 to pass through. The cleaning unit 30 is arranged inside the connection unit 31, and the power unit 32 is connected to the cleaning unit 30. The cleaning module 3 can perform automatic cleaning without disassembling the photovoltaic panel to prevent the hot spot effect.

[0052] The retractable module 4 includes a connection unit 41, a retracting unit 42, an unfolding unit 43 and a power unit 44. The head end of the connection unit 41 is fitted and fixed with the end of the connection unit 1 32, and the connection unit 44 has a cavity inside to allow the flexible photovoltaic panel unit 2 to pass through. The retracting unit 42 is arranged inside the connection unit 41, and the unfolding unit 43 is arranged at the head end of the guide rail 13. The retracting unit 42 and the unfolding unit 43 are both connected to the power unit 44. The flexible characteristics of the flexible photovoltaic panel 22 are utilized to realize the automatic retracting and unfolding of the flexible photovoltaic panel unit 2. When power generation is required, the unfolding unit 43 unfolds the flexible photovoltaic panel unit 2 along the guide rail 13. When it needs to be folded up for maintenance, the retracting unit 42 rolls up the flexible photovoltaic panel unit 2.

[0053] The control unit 5 is installed on the bracket 12 and is signal-connected to the power unit 1 32 and the power unit 2 44 to control the operation of the cleaning module 3 and the retractable module 4 .

[0054] like Figure 1 , Figure 3 As shown, the connection unit 131 includes a set of connecting rails 1311 and a shell 1312. The head end of the shell 1312 is fitted and fixed with the canopy 11, and the interior of the shell 1312 is hollow, and a connecting rail 1311 is arranged inside the shell 1312. The head end of the connecting rail 1311 is fitted and fixed with the end of the guide rail 13 for the slider 23 to slide.

[0055] like Figure 1 , Figure 3 As shown, the second connection unit 41 includes a set of second connection rails 411 and a second housing 412. The head end of the second housing 412 is fitted and fixed with the end of the first housing 312. The interior of the second housing 412 is hollow, and the second connection rail 411 is arranged inside the second housing 412. The head end of the second connection rail 411 is fitted and fixed with the end of the first connection rail 311 for the slider 23 to slide.

[0056] The guide rail 13, the connecting guide rail 1 311 and the connecting guide rail 2 411 form a passage for the flexible photovoltaic panel unit 2, ensuring that the flexible photovoltaic panel unit 2 moves along a specific path during the rolling and unfolding process to avoid deviation or jamming.

[0057] like Figure 3 , Figure 5As shown, the cleaning unit 30 includes a brush cleaning unit 33. The brush cleaning unit 33 includes a brush 331, a brush shaft 332 and a support frame 1 333. The brush 331 is installed on the peripheral side of the brush shaft 332 to contact the surface of the flexible photovoltaic panel 22. The brush shaft 332 is connected to the power unit 1 32, and support frames 1 333 are installed on both sides of the brush shaft 332. The brush shaft 332 is rotatably arranged between the support frames 1 333. The support frame 1 333 is fixed to the inner wall of the housing 1 312.

[0058] When the power unit 1 32 drives the brush shaft 332 to rotate, the brush 331 will scrub the surface of the flexible photovoltaic panel 22, effectively removing the attached dust, dirt, bird droppings and other impurities, and keeping the surface of the flexible photovoltaic panel 22 clean, thereby reducing the formation of hot spots caused by pollutants and affecting the use of the flexible photovoltaic panel 22.

[0059] like Figure 3 As shown, the reeling unit 42 includes a reel 1 421 and a set of support frames 3 422. The support frames 3 422 are fixed to the inner wall of the housing 2 412. The reel 1 421 is rotatably arranged between the support frames 3 422 and is connected to the power unit 2 44. By rotating the reel 1 421, the flexible photovoltaic panel can be rolled up from the unfolded state to achieve the folding of the photovoltaic panel. When the flexible photovoltaic panel 22 is not needed for power generation or sunshade, space can be saved and the flexible photovoltaic panel 22 can be protected from damage.

[0060] like Figure 1 , Figure 4 As shown, the unfolding unit 43 includes a shell body 430, a reel 431 and a support frame 432. The shell body 430 is installed on the roof 11, close to the end of the guide rail 13, and the shell body 430 has a cavity inside. The support frame 432 is fixed to the inner wall of the shell body 430. The reel 431 is rotatably installed between the support frames 432 and is connected to the power unit 44. The unfolding unit 43 releases the flexible photovoltaic panel 22 wound on the reel 1 421 through the rotation of the reel 431, so that it returns to the unfolded state, ensuring that the flexible photovoltaic panel 22 can be quickly and smoothly unfolded to generate electricity or provide shade.

[0061] The combination of the retracting unit 42 and the unfolding unit 43 enables the entire device to be flexibly adjusted according to actual needs. When the illumination area is needed for power generation, the photovoltaic panel can be unfolded. When it is not needed or in bad weather, the photovoltaic panel can be quickly folded up.

[0062] like Figure 1 , Figure 6As shown, the control unit 5 also includes a power detection unit 51 and an image detection unit 52. The power detection unit 51 is connected to the flexible photovoltaic panel unit 2 circuit to monitor the power generation efficiency of the flexible photovoltaic panel unit 2. The image detection unit 52 is arranged above the roof 11 to observe the surface of the flexible photovoltaic panel 22. By monitoring the power generation efficiency and the surface of the flexible photovoltaic panel 22, the control unit can promptly detect possible problems of the flexible photovoltaic panel 22, such as partial shading, excessive dust accumulation, aging, hot spots, etc. When a significant decrease in power generation efficiency is detected, the control unit can issue a warning signal to prompt the user or maintenance personnel to conduct further inspection and maintenance.

[0063] like Figure 2 As shown, the back of the canopy 11 has a shading layer 14, and the back of the flexible photovoltaic panel 22 is provided with an isolation layer 24. The shading layer 14 is made of aluminum-plated polyester film with a thickness of 0.1mm to 0.3mm. The shading layer 14 reflects sunlight, reduces the downward transfer of heat, and allows heat to dissipate upward. The isolation layer 24 uses one of a thermally conductive silicone pad, a thermally conductive gel, and graphene, with a thickness ranging from 0.5mm to 5mm. The isolation layer 24 can dissipate the heat reflected upward to prevent the heat from being transferred upward. The shading layer 14 is combined with the isolation layer 24 to achieve low thermal emissivity downward and high thermal emissivity upward, effectively reducing the downward transfer of heat, while allowing the heat to dissipate upward, providing a better shading effect.

[0064] like Figure 2 As shown, there is a gap between the flexible photovoltaic panel 22 and the roof 11, which is a thermal insulation layer 25, to prevent the flexible photovoltaic panel 22 from directly contacting the roof 11 and causing heat accumulation, while allowing air circulation to help dissipate heat to the surrounding environment.

[0065] Example 2

[0066] like Figure 7 As shown, the difference between this embodiment and embodiment 1 is that the cleaning unit 30 includes a jet cleaning unit 34. The cleaning unit 30 includes a jet cleaning unit 34. The jet cleaning unit 34 includes a compressed air source 340, a compressed air pipeline 341, a nozzle 342 and a support frame 2 343. The compressed air source 340 is installed on the awning body 1 and is connected to the power unit 1 32. One end of the compressed air pipeline 341 is arranged inside the shell 1 312, and the other end is connected to the compressed air source 340. The nozzle 342 is installed on the compressed air pipeline 341. One end of the support frame 2 343 is fixed to the inner wall of the shell 1 312, and the other end is fixed to the compressed air pipeline 341.

[0067] Compared with the brush cleaning method in Example 1, the jet cleaning adopts a non-contact cleaning method, which avoids scratches or wear on the surface of the photovoltaic panel due to physical contact, and helps to protect the integrity of the photovoltaic panel surface and extend its service life. In addition, the high-pressure airflow can penetrate into the tiny gaps and depressions on the surface of the photovoltaic panel, effectively removing some stubborn dirt that is difficult to remove by traditional cleaning methods.

[0068] Example 3

[0069] like Figure 8 As shown, unlike Example 1, in this embodiment, a rotating shaft 15 and a driving mechanism 16 are provided at the connection between the canopy 11 and the bracket 12. The rotating shaft 15 is fixedly connected to the canopy 11 and is rotatably arranged on the bracket 12. The driving mechanism 16 is connected to the rotating shaft 15 in a power connection. The driving mechanism 16 receives a signal from the control unit to rotate the rotating shaft 15, and controls the rotating shaft 15 to rotate, so that the canopy and the flexible photovoltaic panel unit 2 installed thereon can adjust the angle as needed, which helps to adjust the sunshade area of ​​the canopy and the photovoltaic power generation efficiency. For example, in the morning and evening when the sun is low, by increasing the inclination angle of the canopy 11, sunlight can be captured more effectively. When the sun is high at noon, appropriately reducing the inclination angle can reduce the overheating problem caused by direct sunlight.

[0070] Example 4

[0071] like Fig. 9 As shown, different from Example 1, in this embodiment, two layers of flexible photovoltaic panel units 2 are arranged on the roof 11, and the two layers of flexible photovoltaic panel units 2 are arranged vertically. The two layers of vertically arranged photovoltaic panels can make more full use of sunlight incident from different angles, especially in the morning and evening when the solar altitude angle is low, the upper photovoltaic panel will not completely block the lower photovoltaic panel, so that both layers can receive sunlight. In addition, when one layer of photovoltaic panels needs to be maintained or replaced, it will not affect the normal operation of the other layer of photovoltaic panels, thereby ensuring the sunshade and power generation effects.

[0072] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
