Description

Technical Field

[0001] The present application relates to the field of building greening, and in particular to an integrated photovoltaic greening module. Background Art

[0002] With the booming development of renewable energy, the application of photovoltaic power generation on rooftops is becoming more and more common. The traditional installation method of photovoltaic modules usually relies on concrete blocks as counterweights to fix the supporting structure on the roof surface. However, this method has many disadvantages.

[0003] The first is the load problem. The concrete block itself is extremely heavy, which increases the load-bearing burden of the roof. Many roof structures have to be reinforced, which increases the construction cost and construction difficulty. For example, when installing photovoltaic systems on the roofs of some old buildings, the original roof structure has different degrees of deformation and damage risks due to the heavy pressure of the concrete counterweight blocks, and a large amount of money needs to be invested in structural reinforcement and transformation. In addition, the concrete counterweight blocks occupy a considerable space on the roof, but they cannot play an ecological function such as greening, and it is difficult to help improve the urban ecological environment and landscape. In high-density building areas in cities, roof space is already precious. The existence of concrete blocks not only wastes space, but also makes the roof an ecological "dead corner" that cannot provide support for urban biodiversity. In addition, the drainage and thermal insulation performance of concrete blocks is poor, which cannot meet the requirements of green buildings for water resource management and indoor environment regulation. In the hot summer, the roof of the traditional installation method lacks effective thermal insulation, and the heat is easily transferred to the room, which increases the energy consumption of building cooling; when it rains, it is also impossible to effectively store rainwater, resulting in a waste of water resources.

[0004] In recent years, roof greening technology has received much attention and has been widely used. Roof greening has achieved remarkable results in alleviating the urban heat island effect, beautifying the environment, enhancing roof insulation and rainwater utilization efficiency, and has a certain load balancing and fixing effect. In view of this, if the roof photovoltaic system and the roof greening module can be cleverly integrated, and the planting matrix and structure in the greening module can be used instead of the concrete counterweight block as the fixing and counterweight basis, it is expected to achieve the organic integration of photovoltaic power generation and ecological greening, give full play to the advantages of both, and open up a new path for building energy utilization and ecological environment improvement. Summary of the invention

[0024] Embodiment 1

[0025] The embodiment of the present application provides an integrated photovoltaic greening module, which integrates the roof photovoltaic unit and the greening unit, replaces the traditional concrete block with the greening unit as the counterweight and fixed foundation, reduces the roof load, improves the ecological environment, and has the functions of rainwater storage, cooling and heat insulation. Specifically, refer to Figure 1 , the module comprises:

[0026] A photovoltaic unit 1, a photovoltaic support structure 2 and a greening unit 3, wherein the upper end of the photovoltaic support structure 2 is connected to the photovoltaic unit 1 via a mounting clamp 4, and the lower end of the photovoltaic support structure 2 is connected to the greening unit 3 via a fixing member 5;

[0027] The fixing member 5 includes a steel plate 51 and anchor bars 52. The steel plate 51 is connected to the lower end of the photovoltaic support structure 2 by welding, and through holes are provided on both sides of the steel plate 51. The anchor bars 52 are U-shaped structures, and the two anchoring ends of the anchor bars 52 are provided with threads. The anchoring ends of the anchor bars 52 pass through the through holes on both sides of the steel plate 51 from the inside to the outside of the greening unit 3, and then the two anchoring ends of the anchor bars 52 are fixed outside the steel plate 51 by bolts 53.

[0028] The integrated photovoltaic greening module in this scheme is placed on the roof of a building or roof. The photovoltaic unit 1 is a solar photovoltaic panel that generates electricity through solar energy, so as to convert solar energy into electrical energy on the roof of a building or roof, thereby achieving environmental protection and energy saving effects. However, the photovoltaic unit 1 is often a plate-like structure. If it is placed on the roof of a building or roof, it may be blown away due to high wind speed and other reasons. Therefore, it is usually necessary to use a counterweight to fix the photovoltaic unit 1. The present scheme uses a greening unit to replace the traditional concrete counterweight, thereby effectively reducing the unfamiliar burden of the roof, avoiding the roof structure reinforcement project that may be caused by additional loads, and reducing construction costs and safety risks; the present scheme uses a greening unit to replace the traditional concrete counterweight to create a green space on the roof. The growth of plants in the greening unit helps to absorb carbon dioxide, release oxygen, and improve urban air quality; at the same time, it increases the green coverage rate of the city, alleviates the heat island effect, beautifies the urban landscape, provides a habitat for birds and other creatures, and promotes the balance and stability of the urban ecosystem.

[0029] In this solution, the photovoltaic support structure 2 includes an angle steel bracket, a beam and a photovoltaic module pressing block. The upper end of the angle steel bracket is installed on the beam through an installation clip 4, and the beam is fixed to the photovoltaic unit 1 through the photovoltaic module pressing block, thereby realizing the connection between the photovoltaic unit 1 and the photovoltaic support structure 2.

[0030] Specifically, when installing the photovoltaic unit 1, the beam and the photovoltaic unit 1 are usually not directly fixed, which may cause the photovoltaic unit 1 to fail. Therefore, a photovoltaic component pressing block is generally used as a buffer between the beam and the photovoltaic unit 1 for installation. The photovoltaic component pressing blocks used in this solution can be of any specification and are not limited to this.

[0031] In some specific embodiments, the force transmission path is photovoltaic unit 1→beam→installation fixture 4→angle steel bracket→fixing member 5→greening unit 3→roof structure. Therefore, the angle steel bracket of the photovoltaic support structure 2 is used to transfer the load on the photovoltaic unit 1 to the greening unit 3, so that the integrated photovoltaic greening can be kept stable and balanced as a whole. In this solution, the force conditions of the angle steel bracket include the following aspects:

[0032] 1. Axial compression or tension

[0033] When the wind load causes the photovoltaic unit 1 to experience upward pulling force or downward pressure, the angle steel bracket will bear the corresponding axial tension or pressure. In addition, the weight of the photovoltaic unit itself and other additional loads will also cause the angle steel bracket to bear pressure.

[0034] 2. Bending moment and shear force

[0035] Since the connection point between the angle steel bracket and the photovoltaic unit is high, the wind load will generate horizontal thrust, which will generate bending moment and shear force at the bottom of the angle steel bracket, especially for the angle steel bracket under the tilted photovoltaic unit. The photovoltaic unit and the direction of wind load will cause the angle steel bracket to be subjected to lateral thrust in the horizontal direction, causing lateral bending stress and shear force in the angle steel bracket.

[0036] In addition, when the angle steel bracket is under compression, there may be a risk of buckling instability, so the stability of the angle steel bracket needs to be checked.

[0037] In this solution, when calculating the force borne by the angle steel bracket, the external load of the angle steel bracket must be calculated first. The external load includes gravity load and wind load. The formula of the gravity load is as follows:

[0038] W=mg

[0039] Where m is the weight of the photovoltaic unit 1 and the photovoltaic support structure 2, and g is the acceleration of gravity, which is 9.81 m / s 2 .

[0040] The calculation formula for wind load is as follows:

[0041]

[0042] Where Cp,θ represents the corrected pressure coefficient after considering the inclination angle θ, Ap is the actual panel area of ​​the photovoltaic unit, sin(θ) is the effective windward projected area, and V is the wind speed.

[0043] Therefore, the angle steel bracket is abstracted as a load-bearing member, so as to solve the internal force of the cross section of the angle steel bracket. According to the static equilibrium condition, the distribution of the axial internal force N, shear force Q, and bending moment M can be obtained. When the angle steel bracket is only subjected to vertical load, the axial internal force N is equal to the resultant force in the vertical direction, and the formula is expressed as follows:

[0044] N=F v

[0045] Among them, F v is the resultant force in the vertical direction.

[0046] When there is a horizontal force F h When acting on the upper end of the angle steel bracket, shear force Q and bending moment M will be generated at the lower end of the angle steel bracket, and the division of labor is expressed as follows:

[0047] Q=F h

[0048] M=F h ×L

[0049] Where L is the length of the angle steel bracket.

[0050] Then calculate the stress of the angle steel bracket. The total stress of the angle steel bracket includes axial stress and bending stress, that is, σ total =σ axial +σ bend , where σ total is the total stress on the angle steel bracket, σ axial is the axial stress, σ bend is the bending stress, and the calculation formula for the axial stress is as follows:

[0051]

[0052] Where N is the axial internal force, A c is the cross-sectional area of ​​the angle steel bracket.

[0053] The calculation formula of the bending stress is as follows:

[0054]

[0055] Among them, M is the bending moment, y is the distance from the neutral axis of the cross section of the angle steel bracket to the outermost edge of the cross section, and I is the moment of inertia of the cross section of the angle steel bracket.

[0056] However, the shear stress of the angle bracket needs to be checked using the following formula:

[0057]

[0058] If Q is greater than the set value, the shear stress distribution and cross-sectional shape need to be reconsidered.

[0059] Then the buckling of the angle steel is verified based on the Euler buckling formula:

[0060]

[0061] Among them, N cr is the critical buckling force, E is the elastic modulus of the material, I is the cross-sectional moment of inertia of the angle steel bracket, L is the length of the angle steel bracket, and k is the slenderness ratio correction factor.

[0062] The buckling of the angle steel is verified to ensure that the actual axial pressure N is less than a certain safety margin of the critical buckling force:

[0063]

[0064] Finally, the structural strength of the angle bracket is set based on the force it bears. For example, if steel is used, the following must be satisfied: total ≤σ allow If it is not satisfied, it is necessary to increase the radius of the angle steel, select high-strength materials or increase the number of rods.

[0065] Exemplarily, there is a photovoltaic unit with an area size of Ap=4 m2, the total weight of the photovoltaic unit and the photovoltaic support structure is W-500N, and the inclination angle of the photovoltaic unit is θ=30°.

[0066] According to the basic wind pressure formula for a 50-year return period, according to the Code for Loads on Building Structures GB50009-2012, it is 0.5 kN / m 2 The calculated wind load on the photovoltaic panel is 2kN. Assuming that the height of the angle steel bracket is L = 0.5m, in this case, the downward pressure W = 500N borne by the angle steel bracket in the vertical direction and the horizontal wind load F h =2000N. Assuming that the lower end of the angle steel bracket is firmly connected to the greening unit, the angle steel bracket needs to follow the vertical pressure N=500N, the horizontal shear force Q=2000N, and the bending moment caused by the horizontal force M=Q×L=2000N×0.5m=1000N·m,·Y=d / 2.

[0067] Assuming that the angle steel bracket is a hollow square, its cross-sectional length and width are both 50mm, and its inner diameter is 40mm, then the cross-sectional area is 0.0009m 2 , then the moment of inertia of the square section is Y=d / 2,section modulus W=I / Y→7.24×10 -6 , the elastic modulus of steel is E = 2.0 × 10 11 N / m 2 , the yield strength is not less than 235Mpa.

[0068] So the axial stress of the angle steel bracket is Bending stress

[0069] Next, the angle steel bracket is subjected to Euler buckling verification. It is calculated that when the two ends of the angle steel bracket are hinged, the critical buckling force is about 6050N, which is much larger than the actual axial pressure of 500N, and the buckling problem can be ignored. However, the bending stress of the angle steel bracket is about 276.21MPa, which is larger than the yield strength of typical structural steel (above 235MPa). Therefore, one angle steel bracket is not enough to fix the photovoltaic greening panel; at least two angle steel brackets are required. In actual applications, in order to ensure safety, four angle steel brackets are used, that is, four photovoltaic support structures 2 are used to connect the photovoltaic unit 1 with the greening module 3.

[0070] In some specific embodiments, each connection point between the photovoltaic support structure 2 and the photovoltaic unit 1 / greening module 3 is connected using at least two screws.

[0071] Specifically, the total bearing capacity of each screw fixing point is determined by the total load Ftotal transmitted by the photovoltaic unit 1. Thus, we get Ftotal = 2285.08N. Assuming that the screws are evenly distributed, the force on each screw is Fbolt = Ftotal / nbolt. The shear bearing capacity formula for each screw is Fshear = τallowable·Abolt, where τallowable is the allowable shear stress of the screw material, Abolt is the cross-sectional area of ​​the screw, and Abolt = πd2 / 4: the cross-sectional area of ​​the screw.

[0072] Specifically, the allowable shear stress of commonly used screw materials is:

[0073] 1. Ordinary carbon steel (grade 4.8): τallowable≈120MPa

[0074] 2. High strength steel (grade 8.8): τallowable≈300MPa

[0075] Assuming the screw specification is M8 screw, that is, the screw diameter d = 8mm, then Abolt = π(8) 2 / 4=50.27mm 2 =50.27×10 -6 m 2 , the shear bearing capacity of a single ordinary carbon steel screw is Fshear=120·50.27×10 -6 =6.03kN.

[0076] To ensure the safety of the connection, nbolt≥Ftotal·S / Fshearn must be satisfied, where S is the safety factor and S is 2. Therefore, when using ordinary carbon steel screws, nbolt≥2285.08·2 / 6030=1.14, and rounding up means that two screws are needed.

[0077] In this solution, the greening unit 3 includes a planting layer and an aquifer. The planting layer contains a lightweight planting matrix, and vegetation is planted based on the lightweight planting matrix. The aquifer is below the planting layer and is used to store excess water.

[0078] Specifically, the outer shell of the greening unit 3 is a box made of HDPE or PP plastic material, and the lightweight planting matrix is ​​soil or some other matrix that can be used for plant planting. Since the interior of the greening unit 3 is filled with lightweight planting matrix and vegetation, it has a certain self-weight and can be used as a counterweight for the photovoltaic unit 1 to increase the wind resistance of the photovoltaic unit 1. In addition, an aquifer is arranged under the greening unit 3 to store excess water during rain. The excess water stored in the aquifer can not only provide nutrients for the growth of vegetation in the upper planting layer, but also further increase the self-weight of the greening module 3 and improve the wind load resistance of the photovoltaic unit 1.

[0079] In some embodiments, the exploded view of the fixing member 5 is as follows: Figure 2 As shown, the greening unit 3 can be rigidly connected to the photovoltaic support structure 2 through the anchor bars 52 in the fixing member 5, and due to the bonding ability of the lightweight planting matrix in the greening unit 3, the anchor bars 52 can be firmly embedded in the greening unit 3, thereby playing a fixing role.

[0080] In some specific embodiments, a gasket 54 is provided between the bolt 53 and the anchoring end.

[0081] Specifically, a gasket 54 is provided between the bolt 53 and the anchor end to increase the strength of the fixing point, reduce local stress, and improve friction. In addition, the two anchor ends of the anchor bar 52 are fixed outside the steel plate 51 by the bolt 53, thereby ensuring the stability of the overall structure of the integrated photovoltaic greening module.

[0082] In some specific embodiments, the weight of the soil in the greening unit 3 directly generates vertical pressure on the anchor bar 52, thereby providing a fixing force. For example, the density of dry soil is 1200 kg / m 3 , the soil volume V in greening unit 3 = 0.45m 3 , the anchor bar diameter d = 0.02m, the length L = 0.3m, the soil depth h in the greening unit 3 is 0.3m, then the calculation shows that the weight of the soil is Fsoil_weight = ρsoil·g·V = 1200·9.81·0.45 = 5298N.

[0083] Calculate soil pressure Psoil = ρsoil g h = 1200 9.81 0.3 = 3531.6 N / m 2 , soil friction Ffriction=μ·Acontact·Psoi=0.6·0.01885·3531.6=39.9N, the adhesion force of plant roots when not affected by moisture is Froot=k·Vroot Froot=300·0.09=27N, so it can be concluded that the total fixing capacity of the total material in the greening unit 3 for the anchor bar is Ftotal=Fsoil_weight+Ffriction+Froot=5298+39.9+27=5364.9N.

[0084] If the total fixing capacity Ftotal of the greening unit 3 is ≥ the net pull-out requirement Fnet_uplift·S of the photovoltaic unit 1, it means that the greening unit 3 meets the pull-out requirement under the current conditions, where S is the safety factor. From the above calculation content, it can be seen that the net pull-out requirement Fnet_uplift of the photovoltaic unit 1 is the wind load pull-out force minus the dead weight of the photovoltaic unit 1 and the photovoltaic support structure 2, that is, Fnet_uplift=Fuplift-Fgravity=1000-490.5=509.5N, and the value of the safety factor S is set to 2. At this time, Fnet_uplift·S=509.5N×2=1019N, and the total fixing capacity Ftotal of the greening unit 3 is 5364.9N, which is much larger than the actual pull-out requirement Frequired=1019N.

[0085] In some specific embodiments, the photovoltaic unit 1, the photovoltaic support structure 2 and the greening unit 3 can be conveniently disassembled and assembled as needed to meet the needs of different scenarios, and through the standardized greening unit and photovoltaic support structure design, the entire system can be quickly installed, disassembled and replaced. In the later maintenance process, if a component fails or needs to be upgraded, it can be operated conveniently without large-scale dismantling of the entire module, which greatly reduces the maintenance cost and difficulty and improves the sustainability and practicality of the system.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
