Description

Technical Field

[0001] This invention relates to the field of road traffic technology, and specifically to a curved photovoltaic roof. Background Technology

[0002] Most existing highways are built in open areas, which often leads to the following problems:

[0003] 1. Easily affected by weather conditions, leading to traffic disruptions or vehicle stoppages;

[0004] 2. Highway sections located in densely populated areas will generate noise pollution, light pollution, and air pollution, etc.

[0005] 3. Highway lighting, traffic lights, and other related electrical facilities consume a lot of electricity, which is not in line with the current trend of energy conservation and low carbon development.

[0006] Existing technologies, such as Chinese Patent 2008101672528, disclose a mobile tunnel for wind and sand protection and snow resistance in windy areas of railways and highways.

[0027] The curved photovoltaic canopy of this invention, spanning the road, serves two purposes: firstly, it isolates noise generated by vehicles, and secondly, it avoids the impact of extreme weather (such as rain, snow, or strong winds) on vehicles.

The airflow and air quality are ensured by the airflow entering the air duct T and finally being discharged through the outer exhaust structure 5. This can remove the heat generated by the solar panels, allowing the solar panels to generate electricity at a high efficiency under suitable temperatures. The gas PG in the tunnel cavity 1c has a higher temperature. Under thermal pressure, the gas PG will be discharged through the inner exhaust structure 3. This will not only remove the gas containing pollutants from the tunnel cavity 1c, but also further promote the airflow in the tunnel cavity 1c, which is conducive to ensuring the air quality in the tunnel cavity 1c. In addition, the air duct T gives the curved photovoltaic roof better sound insulation and light insulation effects.

[0028] In addition, the lighting windows 6 are set at both ends of the tunnel body, which not only ensures the lighting inside the artificial tunnel, but also avoids the problem of sunlight shining directly into the eyes of vehicle drivers; by using semi-shading solar panels 8, the lighting effect inside the tunnel body is further improved, and the laying area of ​​solar panels is increased.

[0035] The following is in conjunction with the appendix Figure 1-6 The given embodiments further illustrate specific implementations of the curved photovoltaic roof of the present invention. The curved photovoltaic roof of the present invention is not limited to the descriptions of the following embodiments.

[0036] like Figure 1-6As shown, this invention discloses a curved photovoltaic canopy for installation across a road, comprising a tunnel body and a photovoltaic power generation system. The tunnel body includes an inner tunnel layer 1i and an outer tunnel layer 1o, which are installed together from the inside out. An air duct T is provided between the inner tunnel layer 1i and the outer tunnel layer 1o. A tunnel cavity 1c for vehicle passage is provided on the inner side of the inner tunnel layer 1i, and the tunnel cavity 1c extends along the length of the tunnel body. The outer tunnel layer 1o includes at least one outer exhaust structure 5 connecting the external environment of the artificial tunnel and the air duct T. The inner tunnel layer includes at least one inner exhaust structure 3 connecting the tunnel cavity 1c and the external environment. The tunnel body is provided with at least one air intake structure, which includes an outer air intake structure 4 connecting the external environment and the air duct T, and an inner air intake structure 2 connecting the tunnel cavity 1c and the external environment. The photovoltaic power generation system includes a solar panel array, which includes multiple solar panels laid on the outer surface of the outer tunnel layer 1o. Further, the tunnel body is a canopy-like structure.

[0037] This invention features a curved photovoltaic canopy spanning the road, which serves two purposes: firstly, it isolates noise generated by vehicles, and secondly, it avoids the impact of extreme weather (such as rain, snow, or strong winds) on vehicles. Its solar panels are laid on the outer surface of the tunnel's outer layer 1o, generating clean electricity and providing shade to prevent glare for drivers from direct sunlight. Fresh air FA from outside the curved photovoltaic canopy enters the air duct T through the outer air intake structure 4, and then enters the tunnel cavity 1c through the inner air intake structure 2 to promote airflow and ensure air quality. The air flowing into the air duct T and finally discharged through the outer exhaust structure 5 carries away the heat generated by the solar panels, allowing them to generate electricity efficiently at a suitable temperature. The gas PG inside the tunnel cavity 1c has a high temperature and is discharged through the inner exhaust structure 3 under thermal pressure, expelling pollutants from the tunnel cavity 1c and further promoting airflow, thus ensuring air quality within the tunnel cavity 1c.

[0038] like Figure 1-2 As shown in Figures 6 and 7, this is the first embodiment of the curved photovoltaic roof of the present invention.

[0039] like Figure 1-2As shown, the first embodiment of the curved photovoltaic canopy is used to span a road and includes a tunnel body and a photovoltaic power generation system. The tunnel body is an arched canopy structure, which includes an inner tunnel layer 1i and an outer tunnel layer 1o nested together from the inside out. An air duct T is provided between the inner tunnel layer 1i and the outer tunnel layer 1o. A tunnel cavity 1c for vehicle passage is provided inside the inner tunnel layer 1i. The outer tunnel layer 1o includes at least one outer exhaust structure 5 located at the highest point of the outer tunnel layer 1o and connected to the external environment of the tunnel body and the air duct T. The inner tunnel layer 1i includes at least one inner exhaust structure 3 located at the highest point of the inner tunnel layer 1i and connected to the external environment and the tunnel cavity 1c. Preferably, the inner exhaust structures 3 are all connected to the outer exhaust structure. The air structure 5 is arranged opposite to and connected to each other, and the inner exhaust structure 3 is also connected to the tunnel cavity 1c and the air duct T; both ends of the tunnel body are provided with air intake structures, which include an outer air intake structure 4 arranged on the outer layer 1o of the tunnel and connected to the external environment and the air duct T, and an inner air intake structure 2 arranged on the inner layer 1i of the tunnel and connected to the external environment and the tunnel cavity 1c. Preferably, the outer air intake structure 4 and the inner air intake structure 2 are arranged opposite to and connected to each other, and the inner air intake structure 2 is also connected to the tunnel cavity 1c and the air duct T. Preferably, the outer exhaust structure 5 and the inner exhaust structure 3 are both located above the air intake structure; the photovoltaic power generation system includes a solar panel group, which includes multiple solar panels laid on the outer surface of the outer layer 1o of the tunnel.

[0040] like Figure 2 As shown, fresh air FA from the external environment where the tunnel body is located can enter the tunnel cavity 1c from both radial ends of the tunnel body through the air intake structure. The gas PG containing pollutants in the tunnel cavity 1c is discharged from the inner exhaust structure 3 located at the highest point of the inner layer 1i of the tunnel under thermal pressure, thereby ensuring that the air in the tunnel cavity 1c flows in all directions without dead angles and guaranteeing air quality.

[0041] In other embodiments, the outer exhaust structure 5 and the inner exhaust structure 3 may not be located at the highest points of the outer tunnel 1o and the inner tunnel 1i; instead, two outer exhaust structures 5 are arranged as a group, symmetrically positioned on both sides of the highest point of the outer tunnel 1o; and two inner exhaust structures 3 are arranged as a group, symmetrically positioned on both sides of the highest point of the inner tunnel 1i. Of course, the positions of the outer exhaust structure 5 and the inner exhaust structure 3 can be adjusted according to actual needs, and will not be listed here individually.

[0042] The curved photovoltaic canopy of this invention also includes electrical facilities electrically connected to the photovoltaic power generation system, which use electricity generated by the solar panel array. Furthermore, the electrical facilities include lighting devices, and / or traffic light signal devices, and / or alarm devices, and / or broadcasting devices installed within the tunnel body. The solar panel array facilitates carbon neutrality in the artificial tunnel, without generating additional energy consumption.

[0043] The photovoltaic power generation system is also connected to the public power grid to incorporate surplus electricity into the grid.

[0044] Of course, the photovoltaic power generation system also includes equipment cabinets, which include PCS and inverters, etc., to process the DC power generated by the photovoltaic power generation system into AC power that can be connected to the public power grid and electrical energy that can be used by power-consuming facilities.

[0045] Preferred, such as Figure 2 As shown, each of the inner exhaust structures 3 is arranged opposite to and cooperates with the outer exhaust structure 5, so that the gas PG containing pollutants in the tunnel cavity 1c is discharged from the tunnel cavity 1c through the inner exhaust structure 3 and the outer exhaust structure 5 with the shortest path. Furthermore, the inner exhaust structure 3 and the outer exhaust structure 5 are arranged one-to-one opposite to and cooperate with each other.

[0046] Preferably, the inner exhaust structure 3 includes an inner exhaust port disposed on the inner layer 1i of the tunnel and an inner exhaust fan disposed within the inner exhaust port. The inner exhaust fan can improve the exhaust efficiency of gas PG. Furthermore, the tunnel body also includes a heat exchange structure disposed within the inner exhaust port to collect heat energy generated within the tunnel cavity 1c due to vehicle traffic. This heat energy is used to heat the solar panels and equipment cabinet when their temperatures are low, thereby ensuring the photovoltaic power generation system operates efficiently and reliably.

[0047] Preferred, such as Figure 1 As shown, the outer exhaust structure 5 includes an outer exhaust port disposed on the outer layer 1o of the tunnel. Furthermore, the outer exhaust structure 5 also includes a louvered structure covering the outer exhaust structure to prevent foreign objects from entering the air duct T through the outer exhaust port. Furthermore, the tunnel body also includes a covering structure disposed above the outer exhaust structure 5 to prevent rainwater from entering the artificial tunnel from the outer exhaust structure 5.

[0048] When the tunnel body includes an outer exhaust structure 5 and an inner exhaust structure 3, both the outer exhaust structure 5 and the inner exhaust structure 3 are located at the middle position along the length of the tunnel body.

[0049] When the tunnel body includes multiple outer exhaust structures 5 and multiple inner exhaust structures 3, each outer exhaust structure 5 and each inner exhaust structure 3 constitute a group of exhaust structures. Multiple exhaust structures are arranged side-by-side at intervals along the length of the tunnel body, with a spacing of 200-600m between adjacent exhaust structures. Further, the spacing between adjacent exhaust structures is 400m.

[0050] Preferred, such as Figure 1 As shown, the outer air intake structure 4 includes an outer air intake port (not shown in the figure). Furthermore, the outer air intake structure 4 also includes an outer air intake fan (not shown in the figure) disposed within the outer air intake port, which helps improve air intake efficiency and air pressure, thereby improving heat dissipation efficiency for the solar panels and airflow efficiency within the tunnel cavity 1c. Furthermore, the outer air intake structure 4 also includes an outer air intake louver structure for shielding the outer air intake port and the outer air intake fan.

[0051] Specifically, such as Figure 1 As shown, the outer air intake of the outer air intake structure 4 extends along the length of the tunnel body, and the blades of the outer air intake louver are horizontally arranged and extend along the length of the tunnel body.

[0052] Preferably, the outer air intake structure 4 can be opened and closed. When the temperature of the solar panel is below its optimal operating temperature range, the outer air intake structure 4 is closed to prevent fresh air FA from entering the air duct T and carrying away the heat from the solar panel, thus affecting its power generation efficiency. When the temperature of the solar panel is above its optimal operating temperature range, the outer air intake structure 4 is opened to allow fresh air FA to enter the air duct T, thereby reducing the temperature of the solar panel. When the temperature of the solar panel is too low, heat energy is introduced into the air duct T through the heat exchange structure to increase the temperature.

[0053] The optimal operating temperature range of the solar panel is 0℃-50℃. Further, the optimal operating temperature range of the solar panel is 10℃-40℃. Further still, the optimal operating temperature range of the solar panel is 20℃-30℃. It should be noted that the optimal operating temperature range of the solar panel varies depending on the type and specifications of the solar panel.

[0054] Furthermore, the curved photovoltaic canopy also includes a solar panel temperature monitoring mechanism connected to the outer air intake structure 4 for monitoring the temperature of the solar panels and controlling the outer air intake structure 4 to close or open based on the temperature of the solar panels. The solar panel temperature monitoring mechanism includes a microprocessor and temperature sensors. Multiple temperature sensors are connected to multiple solar panels respectively to monitor the temperature of the solar panels. The microprocessor obtains the temperature of the solar panels through the temperature sensors to control the outer air intake structure 4 to close or open. Preferably, the microprocessor also controls a heat exchange structure, which introduces heat energy into the air duct T when the temperature is too low.

[0055] Preferred, such as Figure 1 As shown, the inner air intake structure 2 includes an inner air intake port (not shown in the figure). Furthermore, the inner air intake structure 2 also includes an inner air intake louver structure for shielding the inner air intake port.

[0056] Specifically, such as Figure 1 As shown, the inner air intake of the inner air intake structure 2 extends along the length of the tunnel body, and the blades of the inner air intake louver are horizontally arranged and extend along the length of the tunnel body.

[0057] like Figure 6 As shown, the tunnel body also includes multiple dispersed and enclosed lighting windows 6, and solar panels are laid in the area of ​​the outer layer 1o of the tunnel where no lighting windows 6 are provided.

[0058] Specifically, such as Figure 6 As shown, the tunnel body includes two sets of lighting windows 6 located at its radial ends, each set of lighting windows 6 comprising multiple lighting windows 6 arranged side-by-side at intervals. Further, the solar panel array includes semi-shading solar panels 8 and fully shading solar panels 7; a main shading strip composed of fully shading solar panels 7 is provided at the highest point of the outer layer 1o of the tunnel, extending along the length of the tunnel body; multiple semi-shading strips composed of semi-shading solar panels 8 are provided between the lighting windows 6 and the main shading strip, each semi-shading strip arranged side-by-side at intervals along the length of the tunnel body, with the semi-shading strips staggered from the lighting windows 6; fully shading solar panels 7 are laid between adjacent lighting windows 6.

[0059] The light-transmitting windows 6 are located at both ends of the tunnel body, which not only ensures the lighting inside the artificial tunnel, but also avoids glare for drivers caused by direct sunlight during driving. By using semi-shading solar panels 8, the lighting effect inside the tunnel body is further improved, and the area covered by the solar panels is increased.

[0060] The tunnel body is a single-segment structure or a multi-segment spliced ​​structure, with both ends closed in the length direction.

[0061] The tunnel body also includes at least one vehicle exit and / or at least one vehicle entrance, so that vehicles can enter or exit the tunnel cavity 1c at the middle position of the tunnel body.

[0062] The curved photovoltaic roof also includes at least one air treatment device for treating vehicle exhaust. Each outer exhaust structure 5 is connected to the air treatment device, and the gas discharged from each outer exhaust structure 5 enters the air treatment device for purification. The purification process includes filtration and air washing to remove vehicle exhaust, dust, and soluble harmful gases, reducing air pollution. The air treatment device includes an exhaust fan and an exhaust gas filtration structure. Air is drawn from the tunnel body, passes through the exhaust gas filtration structure, and is then discharged to purify the air inside the tunnel body T. One embodiment of the exhaust gas filtration structure includes an air filter element with fine filter holes, preferably containing activated carbon. Another embodiment of the exhaust gas filtration structure includes an absorbent solution obtained by dissolving alkaline substances and / or substances that react with CO in water, to effectively absorb PM2.5 and toxic gases such as NOx, SO2, and CO from vehicle exhaust. Obviously, the exhaust gas filtration structure is not limited to the technical solution of this embodiment, and other exhaust gas treatment structures or methods can also be used.

[0063] like Figure 3 The image shows a second embodiment of the curved photovoltaic roof of the present invention, which differs from the first embodiment in that:

[0064] The air intake structure remains open, meaning that gas can freely pass through the inner air intake structure 2 and the outer air intake structure 4.

[0065] The inner exhaust fan of the inner exhaust structure 3 can rotate forward and reverse to draw air from and supply air into the tunnel cavity 1c.

[0066] The second embodiment of the artificial tunnel also includes an airway opening and closing structure located between the inlet and outlet of the airway T to control the patency and obstruction of the airway T. Further, the airway opening and closing structure includes a left opening and closing structure L and a right opening and closing structure R disposed within the airway T. The left opening and closing structure L is located between the outer exhaust structure 5 and the air intake structure at one radial end of the tunnel body, and the right opening and closing structure R is located between the outer exhaust structure 5 and the air intake structure at the other radial end of the tunnel body. Further, the left opening and closing structure L includes a lower left opening and closing structure 10-0 and an upper left opening and closing structure 11-0 spaced apart, and the right opening and closing structure R includes a lower right opening and closing structure 10-1 and an upper right opening and closing structure 11-1 spaced apart. The lower left and lower right opening and closing structures 10-0 and 10-1 are located at the radial ends of the tunnel body, respectively, and the upper left and upper right opening and closing structures 11-0 and 11-1 are located on both sides of the outer exhaust structure 5. Specifically, the lower left opening and closing structure 10-0, the upper left opening and closing structure 11-0, the lower right opening and closing structure 10-1, and the upper right opening and closing structure 11-1 are all flip-plate structures. The flip-plate controls the normalization and obstruction of the airway T by reversing its rotation.

[0067] The solar panel temperature monitoring mechanism controls the opening and closing of the air passage structure based on the temperature of the solar panel, so as to control the patency and blockage of the air passage T.

[0068] When the temperature of the solar panel is higher than its optimal operating temperature range, the air passage opening and closing structure switches to the open state to allow air passage T to flow freely. Fresh air FA can enter air passage T through the outer air intake structure 4 and flow within air passage T to be discharged through the outer exhaust structure 5, thereby carrying away the heat from the solar panel and cooling it. When the temperature of the solar panel is lower than its optimal operating temperature range, the air passage opening and closing structure switches to the closed state to block air passage T. Fresh air FA can only enter tunnel cavity 1c through the air intake structure (i.e., the outer air intake structure 4 and the inner air intake structure 2) and cannot enter air passage T or flow within it, thus preventing the airflow within air passage T from further carrying away the heat from the solar panel.

[0069] When the thermal pressure inside the tunnel cavity 1c is high, the inner exhaust fan of the inner exhaust structure 3 switches to forward rotation, drawing air from the tunnel cavity 1c and discharging it through the outer exhaust structure 5, thereby expelling pollutants from the tunnel cavity 1c. When the thermal pressure inside the tunnel cavity 1c is low, the inner exhaust fan of the inner exhaust structure 3 switches to reverse rotation, pressurizing and supplying fresh air FA to the tunnel cavity 1c, causing the polluted gas and pollutants accumulated at the bottom of the tunnel cavity 1c to be discharged through the air intake structures on both sides (i.e., the inner air intake structure 2 and the outer air intake structure 4). The above design enables the pollutants in the tunnel cavity 1c to be discharged from the tunnel cavity 1c in the best way and with the fastest efficiency.

[0070] The outer air intake fan of the outer air intake structure 4 can rotate in both forward and reverse directions. Furthermore, when the outer air intake structure 4 is used to supply air into the tunnel cavity 1c and the air duct T, the outer air intake fan rotates forward to increase the airflow into the tunnel cavity 1c and the air duct T; when the outer air intake structure 4 is used to exhaust air from the tunnel cavity 1c, the outer air intake fan rotates in reverse to accelerate the discharge of pollutants from the tunnel cavity 1c.

[0071] For example, under summer conditions, if the temperature of the solar panel is higher than the optimal operating temperature range of the solar panel and the thermal pressure in the tunnel cavity 1c is high, the air passage opening and closing structure will switch to the open state to make the air passage T unobstructed, the inner exhaust fan of the inner exhaust structure 3 will switch to the forward rotation state, and the outer intake fan of the outer intake structure 4 will switch to the forward rotation state.

[0072] For example, under winter daytime conditions, the temperature of the solar panel is lower than the optimal operating temperature range of the solar panel, while the thermal pressure inside the tunnel cavity 1c is relatively high. In this case, the air passage opening and closing structure switches to the closed state, the inner exhaust fan of the inner exhaust structure 3 switches to the forward rotation state, and the outer intake fan of the outer intake structure 4 switches to the forward rotation state.

[0073] For example, under winter night conditions, the temperature of the solar panel is below the optimal operating temperature range of the solar panel and there is no need to consider the heat dissipation of the solar panel. In this case, the air passage opening and closing structure switches to the closed state. At this time, the thermal pressure in the tunnel cavity 1c is low, and the pollutants in the tunnel cavity 1c mainly accumulate at the bottom of the tunnel cavity 1c. The inner exhaust fan of the inner exhaust structure 3 switches to the reverse state, and the outer intake fan of the outer intake structure 4 switches to the reverse state, so that the pollutants are discharged from the tunnel cavity 1c through the intake structure.

[0074] like Figure 5-6 The image shows a third embodiment of the curved photovoltaic roof of the present invention. The difference between the third embodiment and the artificial tunnel in the first embodiment is that:

[0075] The tunnel body also includes a middle tunnel layer 1m, an inner tunnel layer 1i, a middle tunnel layer 1m, and an outer tunnel layer 1o arranged sequentially from the inside out; the air duct T includes a first air duct T1 arranged between the outer tunnel layer 1o and the middle tunnel layer 1m, and a second air duct T2 arranged between the inner tunnel layer 1i and the middle tunnel layer 1m; the middle tunnel layer 1m includes at least one middle exhaust port 9 connecting the second air duct T2 and the first air duct T1, and the middle exhaust port 9 is located at the highest point of the middle tunnel layer 1m; the middle exhaust port 9 is located above the air intake structure and is arranged opposite to and connected to the outer exhaust structure 5; the inner air intake structure 2 connects the tunnel cavity 1c and the first air duct T1, the outer air intake structure T4 connects the external environment and the first air duct T1, and the inner exhaust structure 3 connects the tunnel cavity 1c and the second air duct T2. Furthermore, the radial ends of the middle layer 1m of the tunnel are respectively connected to the radial ends of the inner layer 1i of the tunnel; the inner layer air intake structure 2 is located below the radial end of the middle layer 1m of the tunnel, and the air duct T is set to cool the solar panel to improve the power generation efficiency, and to make the artificial tunnel have better sound insulation and light insulation effects.

[0076] like Figure 5-6 As shown, the following is the first arrangement of the inner exhaust structure 3 and the air intake structure: The inner tunnel layer 1i is provided with multiple inner exhaust structures 3, which are distributed on both sides of the highest point of the inner tunnel layer 1i. Each inner exhaust structure 3 is located between the middle exhaust port 9 and the air intake structure, for example, it can be located in the middle of the height direction of the inner tunnel layer 1i, so as to quickly and fully exhaust the gas PG containing pollutants in the tunnel cavity 1c. Of course, corresponding exhaust fans can also be installed as needed. Figure 4 As shown, air intake structures are provided at both radial ends of the tunnel body.

[0077] The following is a second arrangement of the inner exhaust structure 3 and the air intake structure: The inner tunnel 1i includes one or more inner exhaust structures 3. Each inner exhaust structure 3 and air intake structure is located on both sides of the highest point of the inner tunnel 1i. That is, an air intake structure is set at one radial end of the tunnel body, and an inner exhaust structure 3 is set at the other radial end of the tunnel body. This allows fresh air FA to enter the tunnel cavity 1c through the air intake structure and then cross the tunnel cavity 1c, which is beneficial to improving the air circulation efficiency in the tunnel cavity 1c.

[0078] The heat exchange structure is located in the middle exhaust port 9 to collect the heat generated by vehicle movement within the tunnel cavity 1c.

[0079] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
