Description

A fixed photovoltaic high-efficiency installation method and photovoltaic bracket Technical Field

[0001] This invention relates to the field of photovoltaic power plant construction technology, and in particular to a fixed high-efficiency photovoltaic installation method and photovoltaic bracket. Background Technology

[0002] The photovoltaic industry is a crucial engine for my country's energy transformation. The construction of photovoltaic power station projects should adhere to the principle of prioritizing conservation, optimizing land allocation, making rational use of land, and maximizing the utilization of unused land. In recent years, my country has focused on promoting the construction of large-scale wind and photovoltaic power base projects, primarily in deserts, Gobi, and arid regions.

[0003] Currently, all components of the photovoltaic power station's support structure and photovoltaic modules are assembled and installed on-site at the pile foundation. The assembly and installation accuracy is manually controlled by each construction team, which has disadvantages such as low installation efficiency, difficulty in guaranteeing installation quality, high construction risks, and poor working conditions for workers. For high pile foundations, high scaffolding needs to be erected for material transportation and installation. The harsh on-site construction environment in desert, Gobi, and arid areas limits the effective working time of workers and reduces the construction progress.

[0004] To address this, a fixed photovoltaic high-efficiency installation method and photovoltaic bracket are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a fixed photovoltaic high-efficiency installation method and photovoltaic bracket, aiming to solve or improve at least one of the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a fixed photovoltaic high-efficiency installation method, comprising the following steps:

[0007] S1: Based on the parameters of the photovoltaic project and the construction efficiency of each process, determine the planned number of automated assembly production lines, transportation and installation equipment for photovoltaic brackets and photovoltaic modules;

[0008] S2: Obtain the actual coordinates of each pile foundation after construction;

[0009] S3: Calculate the connection hole location diagram of each component of the actual photovoltaic support based on the actual coordinates of the pile foundation;

[0010] S3: Input the connection hole diagram of each component of the photovoltaic bracket into the automated assembly production line to assemble the photovoltaic bracket and photovoltaic modules into finished products;

[0012] S5: The assembled finished products are loaded and transported using transportation and installation equipment, and the inkjet printing information is scanned before loading;

[0013] S6: After being transported to the site, the assembled products are connected to the pile foundation to realize the installation of the assembled products.

[0014] Optionally, in step S2, the coordinates of the pile foundation after pile driving are identified by laser scanning or photogrammetry and uploaded to the database. The laser scanning device and the photogrammetry device are mounted on the pile foundation or on a drone.

[0016] Optionally, in step S1, the number n of automated assembly lines is calculated using the following formula:

[0017]

[0018] The number m of transportation and installation equipment configured for a single automated assembly production line is calculated using the following formula:

[0019]

[0020] In the above formulas, x represents the photovoltaic project capacity in kilowatts; q represents the production efficiency of a single automated assembly line in kilowatts per month; T represents the installation period in months; t0 represents the loading and installation time in hours; v represents the speed of the transportation and installation equipment in kilometers per hour; l represents the average transportation distance of the transportation and installation equipment per production line in kilometers; y represents the capacity of the assembly unit of a single automated production line in kilowatts; and c represents the monthly working hours of the transportation and installation equipment in hours per month.

[0021] A photovoltaic mounting system is also provided, comprising:

[0022] Multiple purlins, the tops of which are used for fixing to photovoltaic modules;

[0023] Multiple inclined beams are located below the purlin, and the purlin and the inclined beams are fixed together by a first bolt. The purlin has multiple first elongated holes arranged along the length of the purlin, and the first bolt passes through the first elongated holes.

[0024] Multiple sets of support components are arranged corresponding to multiple inclined beams. Each support component includes two columns located below the inclined beams. The tops of the columns are fixed to the inclined beams by second bolts. The inclined beams have multiple elongated holes arranged along the width of the purlins. The second bolts pass through the elongated holes.

[0025] A connecting component is provided for connecting to the two columns, the connecting component being used for connecting to the pile foundation.

[0026] Optionally, the connecting assembly includes multiple clamps spaced apart vertically, the clamps being fixedly connected to the columns, and a crossbeam being fixedly connected between the two columns by a third bolt: a third elongated hole is opened on the column along the height direction, the third bolt passes through the third elongated hole, the clamps are sleeved on the pile foundation, the crossbeam contacts the top of the pile foundation, and the two columns respectively contact the two opposite outer walls of the pile foundation.

Furthermore, before assembly, the actual coordinates of the pile foundation after construction are obtained, and the pile spacing deviation is calculated based on these coordinates. This information is then transmitted to the automated assembly production line, allowing for adjustments to the actual connection positions of each component of the photovoltaic support structure. This ensures that the assembled product corresponds to the actual position of the pile foundation, thereby greatly improving installation accuracy, efficiency, and quality.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Referring to Figures 1-6, the present invention provides a fixed photovoltaic high-efficiency installation method, comprising the following steps:

[0041] S1: Based on the photovoltaic project parameters and the construction efficiency of each process, determine the planned quantity of automated assembly production line, transportation and installation equipment for photovoltaic brackets and photovoltaic modules 1;

[0042] S2: On-site pile driving to obtain the actual coordinates of each pile foundation 2 after construction;

[0043] S3: Based on the actual coordinates of pile foundation 2, obtain the relative position of pile foundation 2, and calculate the connection hole location diagram of each component of the actual photovoltaic support;

[0044] S3: Input the connection hole diagram of each component of the photovoltaic bracket into the automated assembly production line, and assemble the photovoltaic bracket and photovoltaic module 1 into finished products;

[0045] S4: Mark the assembled finished product with inkjet printing. The inkjet printing information is the on-site installation coordinates of the assembled finished product.

[0046] S5: The assembled finished product is loaded and transported using transportation and installation equipment. Before loading, the inkjet printing information is scanned to obtain the on-site installation coordinates of the finished product.

[0047] S6: After being transported to the site, the assembled product is connected to pile foundation 2 to realize the installation of the assembled product.

[0048] In this embodiment, the automated assembly production line includes a material storage area, an assembly area, and a finished product storage yard, with the following specific functions:

[0049] The material storage area mainly includes the storage areas for various components of the support structure, photovoltaic modules 1, and installation accessories;

[0050] The assembly line assembly area automates the assembly of support components and photovoltaic modules 1;

[0051] Pre-assembled parts storage area, used for temporary storage of pre-assembled parts;

[0052] The assembly line includes a purlin and photovoltaic module 1 installation station, an aircraft head (diagonal beam, column, diagonal brace and clamp) installation station, a purlin and aircraft head installation station, and a quality inspection station, etc. After quality inspection, the finished products are marked with inkjet printing. The transmission mechanism between each installation station includes high-precision ground rails and belt conveyors, etc.

[0053] This invention prefabricates the photovoltaic support structure and photovoltaic modules 1 in the factory before transporting them to the site for connection and installation with the pile foundations 2. This significantly reduces the working time of workers in harsh environments such as deserts, Gobi, and wastelands, and improves construction safety and efficiency. Before assembly, the actual coordinates of the pile foundations 2 after construction are obtained, and the spacing deviation of the pile foundations 2 after construction is obtained based on the actual coordinates. This information is then transmitted to the automated assembly production line to adjust the actual connection positions of each component of the photovoltaic support structure, ensuring that the assembled product corresponds to the actual position of the pile foundations 2. This greatly improves installation accuracy, efficiency, and quality.

[0054] In some optional embodiments, in step S2, the coordinates of the pile foundation 2 after pile driving are identified by laser scanning or photogrammetry and uploaded to the database. The laser scanning device and the photogrammetry device are mounted on the pile foundation 2 or on a drone.

[0055] The obtained coordinates of pile foundation 2 include its horizontal and elevation positions.

[0056] In this embodiment, a high-precision laser scanner is used to obtain the actual coordinates of the pile foundation 2 after construction. The scanner can be mounted on the pile foundation 2 and immediately identified after pile driving is completed, and uploaded to the database; or it can be mounted on a drone to identify the pile foundation 2 in batches; the pile spacing deviation after construction is obtained and recorded as a number.

[0057] In some alternative embodiments, in step S1, the number n of automated assembly lines is calculated using the following formula:

[0058]

[0059] The number m of transportation and installation equipment configured for a single automated assembly production line is calculated using the following formula:

[0060]

[0061] In the above formulas, x represents the photovoltaic project capacity in kilowatts; q represents the production efficiency of a single automated assembly line in kilowatts per month; T represents the installation period in months; t0 represents the loading and installation time in hours; v represents the speed of the transportation and installation equipment in kilometers per hour; l represents the average transportation distance of the transportation and installation equipment per production line in kilometers; y represents the capacity of the assembly unit of a single automated production line in kilowatts; and c represents the monthly working hours of the transportation and installation equipment in hours per month.

[0062] This embodiment is a monopile fixed support system in a certain northwestern Gobi Desert region. The photovoltaic module arrangement is 2×13, with 4 piles and 3 spans, a pile spacing of 4.7m, and a project capacity of 200MW.

[0063] Let the capacity of the photovoltaic project be x, 200 × 10 3 kilowatts; installation period is T, 4 months; for the automated assembly production line, the capacity of the assembly unit is y, in units of 7.2 kilowatts; production efficiency is q, in units of 3 × 10⁻⁶ kilowatts. 4 kW / month; number of production lines is n; for transportation and installation equipment, the travel speed is v, in units of 15 km / h; loading and installation time is t0, 1 hour; the number of equipment paired with a single production line is m; the average transportation distance for transportation and installation equipment with a single production line is l, 3.0 km; as an estimate, the average transportation distance for transportation and installation equipment with n production lines is l / n, in units of km; the monthly working hours for transportation and installation equipment is c, 200 hours / month.

[0064] Then, the following requirements apply to the number of production lines, n:

[0065]

[0066] The following requirements apply to the quantity m of equipment to be transported and installed:

[0067]

[0068] Based on the above formula, there are 2 automated production lines, and each production line is equipped with 20 transport and installation vehicles.

[0069] This formula allows for the precise calculation of the quantity of each piece of equipment, ensuring accurate matching with the construction schedule, reducing overall construction time, and improving construction efficiency.

[0070] A photovoltaic mounting system is also provided, comprising:

[0071] Multiple purlins 3, the tops of which are used for fixing to the photovoltaic module 1;

[0072] Multiple inclined beams 4 are located below the purlin 3. The purlin 3 and the inclined beams 4 are fixed together by the first bolt. Multiple first elongated holes are provided on the purlin 3 along the length direction of the purlin 3. The first bolt passes through the first elongated holes.

[0073] Multiple sets of support components are installed one-to-one with multiple inclined beams 4. Each support component includes two columns 6 located below the inclined beams 4. The tops of the columns 6 are fixed to the inclined beams 4 by second bolts. Multiple elongated holes 7 are provided on the inclined beams 4 along the width direction of the purlins 3. The second bolts pass through the elongated holes 7.

[0074] The connecting component is used to connect to the two columns 6 and to the pile foundation 2.

[0075] Multiple inclined beams 4 and multiple purlins 3 are arranged in a cross-shaped grid pattern, the columns 6 are perpendicular to the ground, and the inclined beams 4 are inclined to the ground.

[0076] In some alternative embodiments, the connecting assembly includes multiple clamps 8 spaced apart vertically, the clamps 8 being fixedly connected to the columns 6, and a crossbeam 9 being fixedly connected between the two columns 6 by a third bolt: a third elongated hole is opened on the column 6 along the height direction, the third bolt passes through the third elongated hole, the clamps 8 are sleeved on the pile foundation 2, the crossbeam 9 is in contact with the top of the pile foundation 2, and the two columns 6 are in contact with the two opposite outer walls of the pile foundation 2 respectively.

[0077] In some alternative embodiments, a diagonal brace 10 is rotatably connected to the column 6, the two columns 6 are located between the two diagonal braces 10, and the end of the diagonal brace 10 away from the column 6 is fixed to the inclined beam 4 by a fourth bolt. The inclined beam 4 has a plurality of fourth elongated holes 11 arranged along the length direction of the inclined beam 4, and the fourth bolt passes through the fourth elongated holes 11. The two diagonal braces 10 are respectively connected to the two ends of the inclined beam 4.

[0078] In some optional embodiments, based on the actual coordinates of the pile foundation 2, the deviation of multiple pile foundations 2 connected to the photovoltaic support is obtained, thereby adjusting the installation position diagrams of the inclined beam 4 and purlin 3, the inclined beam 4 and column 6, the inclined beam 4 and diagonal brace 10, and the column 6 and crossbeam 9 in the photovoltaic support. The left and right deviation of the pile foundation 2 is adjusted by connecting the first bolt to different positions of the first long waist hole. The front and rear deviation of the pile foundation 2 is adjusted by connecting the second bolt and the fourth bolt to different positions of the second long waist hole 7 and the fourth long waist hole 11, respectively. The height deviation of the pile foundation 2 is adjusted by connecting the third bolt to different positions of the third long waist hole.

[0079] In this embodiment, one photovoltaic module 1 corresponds to two pile foundations 2. To improve support stability, two inclined beams 4 are set. Since the actual position of the pile foundation 2 deviates from the predetermined position, if the assembly position of the clamp 8 is not adjusted, the clamp 8 will be misaligned with the pile foundation 2 after transportation to the site, making installation impossible. Therefore, during prefabrication, adjustments are made according to the actual position of the pile foundation. Specifically, the first bolt is connected to different positions of the first elongated hole to adjust the left and right position of the clamp 8. The second bolt is connected to different positions of the second elongated hole 7 to adjust the front and back position of the clamp 8. The fourth bolt is connected to different positions of the fourth elongated hole 11 for installation. The third bolt is connected to different positions of the third elongated hole to adjust the height of the crossbeam 9. Therefore, when installed on two pile foundations 2, the crossbeam 9 can always contact the top of the pile foundation 2 to achieve stable support.

[0080] In some alternative embodiments, the transportation and installation equipment includes a flatbed transport vehicle 12, on which multiple sets of support bases are provided. The support bases are arranged in multiple layers on the flatbed transport vehicle 12, with one support base corresponding to one assembled product. The support base includes multiple downward-facing C-shaped frames 13, which are supported at the bottom of multiple purlins 3. The C-shaped frames 13 between layers are detachably connected.

[0081] In some alternative embodiments, two diagonal braces 14 in a figure-eight shape are fixed between the two vertical bars of the C-shaped frame 13. The diagonal brace 14 on one of the C-shaped frames 13 located on the same set of support bases is close to one side of the two columns 6 in any support component under the corresponding photovoltaic module 1. The C-shaped frame 13 located on the same set of support bases is close to the other side of the two columns 6 in any support component under the corresponding photovoltaic module 1. Two limiting plates are fixed to the top of the C-shaped frame 13. The two limiting plates are respectively close to the outer walls of the two purlins 3 located at the ends.

[0082] The diagonal braces 14 on the two C-shaped frames 13 are respectively attached to the two opposing sides of the two columns 6 in the two sets of support components, thereby achieving left and right limit of photovoltaic module 1. The limit plates are respectively attached to the outer side walls of the two purlins 3 at the ends, thereby achieving front and rear limit of photovoltaic module 1. A damping layer is provided on the contact surface between the C-shaped frame 13 and the purlin 3 to reduce the vibration of photovoltaic module 1. Since the position of the purlin 3 is not adjusted during assembly, the position of the limit plate is fixed, thereby achieving precise positioning of the purlin 3 and improving the accuracy of the limit.

[0083] By arranging the two diagonal braces 14 in a V-shape, they can be close to the column 6 and the diagonal brace 10 without interfering with the clamp 8.

[0084] In some optional embodiments, in step S6, a forklift 15 is used to install the assembled product. The output end of the forklift 15 is fixedly connected to multiple fork teeth 16. The forklift 15 drives the fork teeth 16 to move up and down, back and forth and rotate. Multiple limit blocks are fixedly connected to the fork teeth 16. Limit grooves 17 are opened on the limit blocks. The multiple limit grooves 17 are set one-to-one with multiple purlins 3. When the forklift 15 lifts the photovoltaic bracket, the fork teeth 16 are perpendicular to the purlins 3 and the purlins 3 are located in the limit grooves 17.

[0085] Since the position of the purlin 3 is consistent in each assembled product, when the forklift 15 picks up the finished product, the purlin 3 can fall precisely into the limiting groove 17 to prevent it from falling during installation. The alignment and angle adjustment of the photovoltaic installation finished product are controlled by the fork teeth 16 of the forklift 15. After alignment and placement, the on-site installation workers will connect the photovoltaic installation unit to the lower support structure.

[0087] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
