Description

Technical Field

[0001] This utility model relates to the field of electric vehicle charging station technology, specifically a photovoltaic charging shed in the form of a dougong (bracket set). Background Technology

[0002] With the widespread adoption of electric vehicles, the demand for their supporting infrastructure—electric vehicle charging stations—is also increasing. To achieve efficient energy utilization and sustainable environmental development, integrated photovoltaic carports combining solar power, energy storage, and charging have emerged and are gradually being used in parking lots and vehicle parking areas. These carports not only provide shade and rain protection for vehicles parked beneath them, but also convert solar energy into electrical energy through photovoltaic panels installed on the roof, achieving efficient energy utilization.

[0003] However, the photovoltaic charging sheds currently available on the market are relatively uniform in form, mainly featuring flat roofs. While these designs meet basic functional needs, their aesthetics struggle to blend seamlessly with the architectural styles of historical and cultural cities and traditional districts. Buildings in these ancient city areas are predominantly brick and wood structures, imposing strict requirements on the appearance and dimensions of newly constructed buildings. Existing photovoltaic charging sheds often adopt a modern industrial style and are structurally bulky, clashing with the ancient city's character and cultural atmosphere.

[0004] Furthermore, most existing photovoltaic charging carports use direct-buried electrical wiring. While this method is economical during initial construction, it presents numerous inconveniences for subsequent equipment upgrades and maintenance. Direct-buried cables are susceptible to mechanical damage and environmental corrosion, and the cost of excavating and re-laying cables is high when upgrades, repairs, or expansions are needed, potentially causing environmental damage as well. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present invention provides a photovoltaic charging carport in the form of a dougong bracket, including a roof component, two connectors and several column assemblies, and photovoltaic tiles are provided on the upper surface of the roof component.

[0006] The column assembly includes a first column, a second column, a first bracket set, a second bracket set, and a connecting member. The first and second columns are vertically arranged, forming a pipe gallery area below the ground level between them. The first bracket set connects to the upper ends of the first and second columns, and its length is greater than the interval between them. Both ends of the first bracket set connect to the lower sides of the roof structure. The second bracket set connects to the first and second columns, and its length is shorter than the first bracket set. The upper ends of the second bracket set are connected to the lower ends of the first bracket set via connecting members. This effectively improves the overall structural stress, reduces the span of the structure, and lowers the stress level. Of course, similar bracket sets can be added below the second bracket set to further optimize the structure.

[0007] The column components are arranged parallel and collinearly, meaning they are aligned on a single line. Two connectors connect the first and second columns of each component, forming a unified structure and strengthening the overall structure of the carport. After the carport is built, the underground utility tunnel area will form a utility tunnel, facilitating cable laying and future inspection and maintenance.

[0008] Furthermore, the column assembly also includes a first base and a second base. The first column is vertically mounted on the first base, and the second column is vertically mounted on the second base. The first base and the second base are buried underground, making the overall structure more stable.

[0009] Furthermore, it also includes retaining walls and several movable cover plates. Each first and second column in each column assembly is connected to a retaining wall at a corresponding underground position. Several movable cover plates are removable and connect to the retaining walls on both sides. The retaining walls can be formed by concrete casting, integrating the underground portions of the first and second columns in each column assembly into a single unit. This increases the overall rigidity of the utility tunnel, helping to resist the compression of the soil by vehicle loads. The movable cover plates facilitate subsequent inspection and maintenance, and also make the installation and adjustment of charging piles more flexible.

[0010] Furthermore, it also includes a connecting part and a base. The connecting part connects the upper part of the first base and the upper part of the second base to strengthen the structural strength of the pipe gallery; the base connects the upper part of the first base and the bottom of the second base to further enhance the overall strength of the carport.

[0011] Furthermore, the roof component includes several longitudinal steel beams and several arc-shaped steel beams, which are interconnected to form a symmetrical arc-shaped grid frame. After photovoltaic tiles are laid on the arc-shaped roof component, it is beneficial for the drainage of rainwater and dust, and it can also optimize the load-bearing structure of the roof. The first bracket connects two of the longitudinal steel beams, making the connection between the first bracket and the roof component more reliable.

[0012] Furthermore, it also includes connecting columns. The roof components are provided in several groups. The lower side of the roof component near the middle is connected to the upper side of the roof component near the end through the connecting columns, so that ventilation openings are formed between adjacent roof components, which facilitates the air circulation under the roof components of large-scale carports.

[0013] Furthermore, the column assembly also includes a third bracket component. The first and second columns each have a third bracket component at their upper ends. The third bracket component is positioned along the direction of the connecting member, and both ends of the third bracket component are connected to the lower sides of the corresponding connecting member via receiving members, thus optimizing the connection structure between the first column, the second column, and the connecting member. Of course, similar bracket components can be added below the third bracket component to further optimize the structure.

[0014] Furthermore, both ends of the first and second bracket pieces are higher than the connection points on the first and second columns, making the ends of the first and second bracket pieces higher, which facilitates connection with the roof components and also improves the overall load-bearing structure.

[0015] Furthermore, the first and second columns are made of H-beams, and cover plates are provided at the grooves on both sides of the H-beams. The cover plates and grooves form a cable routing channel, which is used to install cables. This can effectively reduce the number of installation components and also protect the cables using the H-beams.

[0016] Furthermore, it also includes batteries, charging piles, and cables. The charging piles are connected to the mains power, the batteries can store the electrical energy generated by the photovoltaic tiles and provide a stable power supply to the charging piles, the cables are installed in the pipe gallery area, and the charging piles are installed on the upper side of the movable cover plate.

[0017] This invention significantly improves the overall structural stress through the addition of first and second bracket sets. The bracket sets provide vertical support for the roof components, effectively reducing their span and stress levels. Simultaneously, the addition of supporting columns allows the internal forces of the roof components to be distributed to the column tops through beam-column joints and the bracket sets, effectively reducing the peak internal force at the column tops and lowering the stress levels in the supporting columns. The bracket sets not only play a crucial role in structural stability but also fully showcase the stylistic elements of traditional architecture.

[0018] The photovoltaic canopy in this invention features a double-column design, which effectively reduces the cantilever length of the roof while maintaining the same roof dimensions, making it easier to achieve a lightweight roof effect. Simultaneously, the horizontal structure changes from a single-column structure to a single-span frame structure, further improving structural stability and anti-overturning capabilities. The foundations of the double columns are integrated with the utility tunnel, forming a unified design. This effectively increases the overall rigidity of the utility tunnel, making it more resistant to the pressure of vehicle loads on the soil, and also avoids the obstruction of wiring passage within the utility tunnel caused by commonly used single-column foundations. Double-row, multi-layer supports can be installed on the side walls of the utility tunnel to accommodate multi-functional data and power lines such as optical cables and electrical cables. Charging piles and DC chargers are installed above the movable cover, facilitating future inspection and maintenance. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] See Figure 1 The photovoltaic charging carport in the form of a dougong bracket in this embodiment includes a roof component 1, two connectors 2 and several column assemblies 3, and photovoltaic tiles 4 are provided on the upper surface of the roof component 1.

[0031] See Figure 2 , Figure 3 The column assembly 3 includes a first column 5, a second column 6, a first bracket 7, a second bracket 8, and a supporting member 9. The first column 5 and the second column 6 are vertically arranged, forming a pipe gallery area 10 below the ground level between them. The first bracket 7 is connected to the upper ends of the first column 5 and the second column 6. The lengths of the first bracket 7 and the second bracket 8 are greater than the interval between the first column 5 and the second column 6. The two ends of the first bracket 7 are connected to the lower side of the roof component 1. The second bracket 8 is connected to the first column 5 and the second column 6, and its length is shorter than that of the first bracket 7. The upper ends of the second bracket 8 are connected to the lower ends of the first bracket 7 via the supporting member 9. This effectively improves the overall structural stress, reduces the span of the structure, and lowers the stress level. Of course, similar brackets can be added below the second bracket 8 to further optimize the structure. In this embodiment, a fourth bracket 11 is also provided below the second bracket 8 to further optimize the structure.

[0032] See Figure 4Each column assembly 3 is arranged in parallel and collinear. Two connectors 2 connect the first column 5 and the second column 6 in each column assembly 3 respectively, so that each column assembly 3 is connected as a whole, strengthening the overall structure of the carport. After the construction of the carport, each column assembly 3 can form a pipe gallery in the underground pipe gallery area 10, which is convenient for the subsequent laying of cables 28 and for future inspection and maintenance.

[0033] The column assembly 3 also includes a first base 12 and a second base 13. The first column 5 is vertically mounted on the first base 12, and the second column 6 is vertically mounted on the second base 13. The first base 12 and the second base 13 are buried underground, making the overall structure more stable.

[0034] Furthermore, the system also includes retaining plates 14 and several movable cover plates 15. Each first column 5 and each second column 6 in each column assembly 3 is connected to the retaining plate 14 at a corresponding position below ground level. The movable cover plates 15 are removably connected to the retaining plates 14 on both sides. The retaining plates 14 can be formed by concrete casting, integrating the underground portions of the first column 5 and the second column 6 in each column assembly 3 into a single unit. This increases the overall rigidity of the utility tunnel, helping to resist the compression of the soil by vehicle loads. The movable cover plates 15 facilitate subsequent inspection and maintenance, and also make the installation and adjustment of the charging piles 27 more flexible.

[0035] Preferably, it also includes a connecting part 16 and a base 17. The connecting part 16 connects to the upper part of the first base 12 and the upper part of the second base 13 to strengthen the structural strength of the pipe gallery; the base 17 connects to the upper part of the first base 12 and the bottom of the second base 13 to further enhance the overall strength of the carport.

[0036] The roof component 1 includes several longitudinal steel beams 18 and several arc-shaped steel beams 19, which are interconnected to form a symmetrical arc-shaped grid frame. After photovoltaic tiles 4 are laid on the arc-shaped roof component 1, it facilitates the drainage of rainwater and dust, and also optimizes the roof's structural load-bearing capacity. A first bracket 7 connects two of the longitudinal steel beams 18, making the connection between the first bracket 7 and the roof component 1 more reliable. For aesthetic purposes, decorative strips 29 are also provided on the roof component 1.

[0037] Preferably, it also includes connecting columns 20. The roof component 1 is provided with several groups. The lower side of the roof component 1 near the middle is connected to the upper side of the roof component 1 near the end through the connecting columns 20, so that ventilation openings 21 are formed between adjacent roof components 1, which facilitates the air circulation under the large-size carport roof component 1.

[0038] The column assembly 3 also includes a third bracket 22. The first column 5 and the second column 6 are each provided with a third bracket 22 at their upper ends. The third bracket 22 is arranged along the direction of the connector 2, and both ends of the third bracket 22 are connected to the lower sides of the corresponding connector 2 via receiving members 9, thus optimizing the connection structure of the first column 5, the second column 6, and the connector 2. Of course, similar brackets can be added below the third bracket 22 to further optimize the structure. In this embodiment, a fifth bracket 23 is also provided below the third bracket 22 to further optimize the structure.

[0039] Preferably, both ends of the first bracket member 7 and the second bracket member 8 are higher than the connection points on the first column 5 and the second column 6, making the ends of the first bracket member 7 and the second bracket member 8 higher, which facilitates connection with the roof component 1 and also improves the overall load-bearing structure. More preferably, the first bracket member 7 and the second bracket member 8 are V-shaped to optimize the load-bearing structure.

[0040] Preferably, the first column 5 and the second column 6 are made of H-beams. Cover plates 24 are installed in the grooves on both sides of the H-beams, forming a cable tray 30 between the cover plates 24 and the grooves. The cable tray 30 is used to install cables, which can effectively reduce the number of installation components and also utilize the H-beams to protect the cables. (See [reference]). Figure 5 Further preferably, a light box 25 is provided between the first column 5 and the second column 6, which can be used for advertising operations and also provides lighting for part of the space; a column top light 26 is also provided on the first bracket 7, which can further improve the lighting.

[0041] This embodiment also includes a storage battery, a charging pile 27, and a cable 28. The charging pile 27 is also connected to the mains power. The storage battery can store the electrical energy generated by the photovoltaic tile 4 and provide a stable power supply to the charging pile 27. The cable 28 is installed in the pipe gallery area 10, and the charging pile 27 is installed on the upper side of the movable cover plate 15 for easy maintenance and upkeep during later use.

[0042] Common parking lot canopies require minimal support and large overhangs to provide necessary shade for vehicles while facilitating parking and maximizing the area for photovoltaic modules. To maintain consistency with traditional wooden structures, the canopy structure should primarily consist of small-sized steel beams and columns as load-bearing components. All internal forces are borne solely by the beams and columns. The large span of the steel beams and the limited connections between them result in high internal forces and stress levels in the beams and columns. Furthermore, the beams and columns are connected only by a single node, leading to stress concentration at that node and low structural efficiency. (See [reference needed]). Figure 6 .

[0043] This invention significantly improves the overall structural stress distribution by adding brackets at the junction of steel beams and columns. The brackets provide vertical support for the small-sized steel beams, effectively reducing the span and stress level of the beams. Furthermore, by increasing the number of connections between the steel beams and columns, the internal forces of the steel beams are distributed to the column tops through the beam-column joints and the brackets, effectively reducing the peak internal force at the column tops and lowering the stress level of the steel columns. (See also...) Figure 7 , Figure 8 The bracket set not only plays an important role in structural stability, but also fully demonstrates the stylistic elements of traditional architecture in terms of form.

[0044] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
