Description

Technical Field

[0001] This invention relates to the field of residential photovoltaic construction technology, and more specifically, to a construction method for a solar power station in a sunroom. Background Technology

[0002] A solar-powered rooftop solar power station is a special type of distributed residential solar power station, combining solar photovoltaic modules with modern architectural design as an add-on to a residence. By utilizing the user's roof space to install photovoltaic modules, it absorbs sunlight and converts it into electricity, thus providing a more convenient lifestyle. Simultaneously, the design of a solar-powered rooftop solar power station emphasizes practical functions such as large spans between columns and rain and sun protection, providing users with more living space. However, due to factors such as the rainy season, hot weather, and complex construction procedures, the construction period for solar-powered rooftop solar power stations is long and the construction efficiency is low, preventing their widespread application.

[0003] In addition, such as Figure 10 As shown, due to the complex drainage structure and the presence of false beams on both cantilevered ends of the roof truss to support the solar photovoltaic modules, the risk of construction workers working at heights is increased, making the construction of the photovoltaic solar power station more difficult and resulting in lower construction efficiency.

[0004] Therefore, how to improve the construction efficiency of solar power stations has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a construction method for a sunroom power station, so as to improve the construction efficiency of the sunroom power station.

The cross-shaped positioning rod includes a first positioning part and a first connecting part. The cross-shaped positioning rod is connected to the square frame through the first connecting part. The square frame is provided with a first marking part at each of its four corners. The first positioning part is provided with a distance marker, which is used to measure the movement distance of the positioning tool.

[0014] Optionally, in the above-mentioned construction method for the sunroom power station, the first positioning part includes a first positioning rod and a second positioning rod arranged perpendicularly to the first positioning rod, the distance marker is arranged perpendicularly on the first positioning rod, and the distance between the distance marker and the second positioning rod is equal to the diameter of the mounting hole of the base.

[0015] Optionally, in the above-mentioned construction method of the sunroom power station, the square frame is provided with handrails on two sides parallel to the first positioning rod to facilitate the movement of the positioning tool, and a first connecting rod is provided between the two handrails to fix the square frame and the handrails.

[0016] Optionally, in the above-mentioned construction method for the sunroom power station, in the step of installing the base, by aligning the first positioning part of the cross positioning rod with the center line of the base, and moving the positioning tool along the direction of the first positioning rod, the distance marker is aligned with the center line of the base. The first marking part marks the position of the mounting hole of the base on the roof, and the center of the mounting hole of the base is aligned with the midpoint of the marking line.

[0017] Optionally, in the above-mentioned construction method for the sunroom power station, the column marking tool includes a contour positioning frame and a positioning rod assembly connected to the contour positioning frame. The contour positioning frame includes a second marking part, and the positioning rod assembly includes a second positioning part and a second connecting part. The second positioning part is disposed on the second connecting part, and the projection of the second connecting part on the roof coincides with the center line of the base. The contour positioning frame has the same cross-section as the column.

[0018] Optionally, in the above-mentioned construction method of the sunroom power station, the second connecting part includes two second connecting rods arranged perpendicularly to each other, each second connecting rod is provided with two second positioning parts, and the distance between the two second positioning parts on each second connecting rod is equal to the side length of the base, so that the two second positioning parts on each second connecting rod abut against the opposite side of the base respectively.

[0019] Optionally, in the above-mentioned construction method of the sunroom power station, in the step of positioning the column, the second positioning part is placed on the center line of the base and the second positioning part abuts against the side of the base, and the corner outline of the column is marked on the base in sequence along the second marking part of the outline positioning frame.

[0020] Optionally, in the above-mentioned construction method for the sunroom power station, in the step of assembling the frame, there are multiple inclined beams, and each of the inclined beams is symmetrically fixed to the column to form a ridge at the top of the frame. The horizontal beams include a first horizontal beam and a second horizontal beam. The horizontal beams are connected between adjacent inclined beams in a direction parallel to the ridge. The first horizontal beam is located at the full span of the frame, and the second horizontal beam is located at the side span of the frame.

In the base centerline positioning step, a laser level is used on the roof according to the construction drawings to locate the base centerline, and a chalk line is used to mark the centerline. In the base installation step, the first positioning part of a locating tool engages with the base centerline to position the tool at the centerline. Simultaneously, the first marking part of the locating tool quickly marks the base hole positions on the base centerline. Aligning the mounting holes with these holes allows for rapid installation of the base at the base centerline, improving installation efficiency. In the column positioning step, the second positioning part of a column marking tool engages with the base centerline to position the tool. Simultaneously, the second marking part of the column marking tool marks the base hole positions on the centerline. The four corners of the columns are marked sequentially, unaffected by base installation errors, and have good fault tolerance. Even if the base is installed crookedly, the column marking tool can be used to position the column on the same horizontal line as the base centerline, improving the efficiency and accuracy of column positioning. In the frame assembly step, the columns are fixed according to the markings on the base. Horizontal tie beams are installed and fixed on adjacent columns, and diagonal beams are fixed to the columns. Horizontal crossbeams are then installed and fixed on the diagonal beams to form the frame. Drainage channels are installed on the frame to allow rainwater to drain out along them. In the photovoltaic panel installation step, the photovoltaic panels are installed on the horizontal crossbeams, with the upper surface of the photovoltaic panels flush with the opening of the drainage channels, allowing rainwater on the photovoltaic panels to flow into the drainage channels, thus completing the entire construction process of the solar power station.

[0023] In existing technologies, the construction cycle of solar power stations is long and the construction efficiency is low due to factors such as the rainy season, hot weather, and complex procedures, which prevents the widespread application of photovoltaic solar power stations. The construction method for solar power stations provided by this invention allows for the rapid marking of base hole positions on the base centerline using a positioning tool during the base installation step. By aligning the mounting holes of the base with these positions and fixing them with expansion bolts, the base can be quickly installed on the base centerline, improving installation efficiency. Simultaneously, in the column positioning step, a column marking tool allows for the rapid marking of the four corners of the column on the base, unaffected by base installation errors and with good fault tolerance. Even if the base is installed crookedly, the column marking tool and the positioning on the base centerline ensure that the column is installed on the same horizontal line, reducing repetitive construction and improving the efficiency and accuracy of column positioning. By using positioning and column marking tools, the efficiency of component positioning and installation is improved, thereby increasing the construction efficiency of the solar power station.

[0044] The core of this invention is to provide a construction method for a sunroom power station, so as to improve the construction efficiency of the sunroom power station.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] like Figure 1 As shown, this invention discloses a construction method for a solar power station, including step S100, positioning the base centerline; step S101, installing the base; step S102, positioning the column; step S103, assembling the frame; and step S104, installing the photovoltaic panels. It should be noted that in the prior art, due to factors such as the rainy season, hot weather, and complex procedures, the construction cycle of solar power stations is long and the construction efficiency is low, preventing the widespread application of photovoltaic solar power stations. Furthermore, as... Figure 10 As shown, the drainage channel 400 of the photovoltaic power station is arranged in a relatively complex manner. The traditional drainage channel 400 includes a horizontal channel, a vertical channel, and a collection channel 402. The horizontal channel includes a first horizontal channel 403 and a second horizontal channel 405. The vertical channel includes a second vertical channel 406 and a main vertical channel 401 located in the middle area of ​​the roof truss 303. At the same time, decorative steel beams 301 are provided at the ends of both sides of the roof truss 303. The decorative steel beams 301 do not have a drainage function, so rainwater from the horizontal channel cannot be discharged from both sides of the roof truss 303. Moreover, rainwater from the photovoltaic panel 500 can only flow into the second vertical channel 406. The second transverse water channel 405 allows rainwater to flow into the longitudinal main water channel 401, and finally into the collection channel 402. This makes the drainage structure of the roof truss 303 complex and the drainage paths intricate, resulting in some rainwater not being able to drain, leading to low roof drainage efficiency for the photovoltaic power station. Furthermore, the complex drainage structure, coupled with the presence of false beams on the cantilevered ends of the roof truss to support the solar photovoltaic modules, increases the risk of high-altitude work for construction workers, making the construction of the photovoltaic power station more difficult and thus resulting in lower construction efficiency. The construction method for the photovoltaic power station disclosed in this invention improves the construction efficiency of the photovoltaic power station. For example, Figures 1 to 14 As shown, the construction method of this sunroom power station specifically includes:

[0047] Step S100: Position the center line of the base;

[0048] According to the construction drawings, the center line 104 of the base is located on the roof using a laser level, and then marked with a chalk line. Specifically, first, according to the dimensional requirements of the construction drawings, the center line 104 of the base is located using a laser level, and then the center line 104 of the base is marked on the roof using a chalk line.

[0049] Step S101: Install the base;

[0050] Using a positioning tool 100, mark the base hole positions at the center line 104 of the base. Drill holes at these positions using an impact drill. Clean the dust from the holes with a blower. Then, inject waterproof structural adhesive into the holes and install expansion bolts. Once the mounting holes 3022 of the base 3021 align with the base hole positions, secure them with the expansion bolts to install the base 3021 at the center line 104 of the base. For example... Figure 2 As shown, the positioning tool 100 is provided with a first positioning part 1021 and a first marking part 1025. The first positioning part 1021 cooperates with the center line 104 of the base to ensure the positioning of the positioning tool 100 on the center line 104 of the base. The first marking part 1025 marks the hole position of the base.

[0051] like Figure 2 As shown, in one specific embodiment, the positioning tool 100 includes a square frame 101 and a cross-shaped positioning rod 102 disposed below the square frame 101. The cross-shaped positioning rod 102 includes a first positioning part 1021 and a first connecting part 1024. The cross-shaped positioning rod 102 is connected to the square frame 101 through the first connecting part 1024. First marking parts 1025 are provided at the four corners of the square frame 101. Distance markers 1026 are provided on the first positioning part 1021 to measure the moving distance of the positioning tool 100. The first positioning part 1021 includes a first positioning rod 1022 and a second positioning rod 1023 disposed perpendicular to the first positioning rod 1022. The first positioning rod 1022 and the second positioning rod 1023 are respectively perpendicular to the sides of the square frame 101, while the distance marker 1026 is perpendicularly disposed on the first positioning rod 1022. Furthermore, as... Figure 4 As shown, the distance between the marker 1026 and the second positioning rod 1023 is defined as L, and the diameter of the mounting hole 3022 of the base 3021 is defined as D. The distance L between the marker 1026 and the second positioning rod 1023 is equal to the diameter of the mounting hole 3022 of the base 3021. In this embodiment, the first marking part 1025 is a steel nail vertically disposed at the four corners of the square frame 101, so that when the positioning tool 100 moves, the first marking part 1025 can draw a marking line 105 on the roof. Of course, the first marking part 1025 can also use other marking components with marking functions, such as a scriber, etc., which will not be listed here.

[0052] like Figures 3 to 5 As shown, when it is necessary to mark the base hole position at the center line 104 of the base, as follows: Figure 3 and Figure 4 As shown, by aligning the first positioning part 1021 of the cross positioning rod 102 with the center line 104 of the base, and moving the positioning tool 100 along the direction of the first positioning rod 1022, the distance marker 1026 is made to coincide with the center line 104 of the base. Figure 5 As shown. Simultaneously, the first marking part 1025 marks the position of the mounting holes 3022 of the base 3021 on the roof surface with marking lines 105, and the length of the marking line 105 is L. The midpoint of the marking line 105 is the center position of the mounting holes 3022 of the base 3021. Furthermore, the first marking parts 1025 at the four corners of the square frame 101 can simultaneously mark the positions of the four mounting holes 3022 on the base 3021, improving the positioning efficiency of the base holes. When installing the base 3021, simply align the edges of the four mounting holes 3022 on the base 3021 with the two ends of the marking line 105, that is, align the center position of the mounting holes 3022 on the base 3021 with the midpoint position of the marking line 105, thus completing the positioning of the base 3021. Then, use expansion bolts to fix the base 3021 to the base centerline 104, thereby improving the installation efficiency of the base 3021. Figure 6 As shown.

[0053] like Figure 2 As shown, to facilitate the operator's movement of the positioning tool 100, handrails 103 are respectively provided on both sides of the square frame 101 to facilitate movement of the positioning tool 100. The handrails 103 are located on both sides of the square frame 101 parallel to the first positioning rod 1022, allowing the operator to easily push the positioning tool 100 along the direction of the first positioning rod 1022. This causes the first marking part 1025 to mark the position of the mounting hole 3022 of the base 3021 on the roof surface. Simultaneously, a first connecting rod 1031 is provided between the two handrails 103 to fix the square frame 101 and the handrails 103, improving the overall connection strength and stability of the positioning tool 100. It should be noted that the positioning tool 100 can be made of steel bars and manufactured by welding.

[0054] Step S102, column positioning;

[0055] The four corners of the column 302 are marked and positioned on the base 3021 using the column marking tool 200. For example... Figure 7 As shown, the column marking tool 200 is provided with a second positioning part 2021 and a second marking part 2011. The second positioning part 2021 cooperates with the center line 104 of the base to ensure the positioning of the column marking tool 200 on the center line 104 of the base. The four corners of the column 302 are marked by the second marking part 2011.

[0056] like Figure 7As shown, in one specific embodiment, the column marking tool 200 includes a contour positioning frame 201 and a positioning rod assembly 202 connected to the contour positioning frame 201. The contour positioning frame 201 includes a second marking portion 2011, and the contour positioning frame 201 has the same cross-section as the column 302, that is, the shape and size of the cross-section of the contour positioning frame 201 and the column 302 are the same. The second marking portion 2011 is located at the four corners of the contour positioning frame 201, such as... Figure 7 As shown. Meanwhile, the positioning rod assembly 202 includes a second positioning part 2021 and a second connecting part 2022. The second positioning part 2021 is disposed on the second connecting part 2022, and the projection of the second connecting part 2022 on the roof coincides with the center line 104 of the base. Specifically, the second connecting part 2022 includes two mutually perpendicular second connecting rods 2023. Each second connecting rod 2023 is provided with two second positioning parts 2021. The second positioning parts 2021 are vertically arranged below the second connecting rod 2023 so that the second positioning parts 2021 contact the roof surface, thereby facilitating the second positioning parts 2021 to coincide with the center line 104 of the base. The distance between the two second positioning parts 2021 on each second connecting rod 2023 is equal to the side length of the base 3021, so that when the column marking tool 200 is placed on the base 3021, the two second positioning parts 2021 on each second connecting rod 2023 abut against the opposite side of the base 3021 to position the column 302 in a horizontal position.

[0057] like Figure 8 and Figure 9 As shown, when it is necessary to mark the position of the column 302 on the base 3021, such as Figure 8 As shown, the second positioning part 2021 of the column marking tool 200 is placed on the center line 104 of the base, while the second positioning part 2021 abuts against the side of the base 3021. At this time, a marker is used to mark the corner outline 3023 of the column 302 on the base 3021 along the second marking part 2011 of the outline positioning frame 201, as shown. Figure 9 As shown, this completes the positioning of the column 302. The second positioning part 2021 of the column marking tool 200 is aligned with the center line 104 of the base to position the column marking tool 200 on the center line 104. Simultaneously, a marker is used to mark the four corners of the column 302 on the base 3021 along the second marking part 2011 of the column marking tool 200. This method is unaffected by installation errors of the base 3021 and has good fault tolerance. Even if the base 3021 is installed crookedly, the positioning of the column marking tool 200 with the center line 104 ensures that the column 302 is installed on the same horizontal line, improving the efficiency and accuracy of the column 302 positioning.

[0058] Step S103: Assemble the frame;

[0059] The uprights 302 are fixed according to the markings on the base 3021, and horizontal tie beams are installed on adjacent uprights 302 to improve the overall stability of the uprights 302. Inclined beams 3032 are fixed to the uprights 302, and horizontal crossbeams 304 are installed on the inclined beams 3032 to form a frame 300. Drainage channels 400 are installed on the frame 300 to allow rainwater to drain out along them. Specifically, as... Figure 11 As shown, multiple uprights 302 are positioned and welded to the corresponding bases 3021 according to the markings on the bases 3021. Simultaneously, multiple diagonal beams 3032 are symmetrically fixed to the uprights 302 and connected by welding to form multiple parallel tripods 3031. Diagonal braces connect the diagonal beams 3032 and the uprights 302, thereby improving the connection strength between the uprights 302 and the diagonal beams 3032 and ensuring the stability of the tripods 3031. A horizontal beam 304 is welded to the upper surface of the diagonal beams 3032. In this embodiment, the horizontal beam 304 is made of square steel tubing and connects each tripod 3031, thus forming the roof truss 303 portion of the frame 300. Figure 11 As shown, the horizontal beam 304 connects the various triangular frames 303, which not only improves the overall stability of the roof truss 303 but also provides support for the installation of the photovoltaic panels 500. Furthermore, the two ends of the horizontal beam 304 extend from the triangular frames 1031 at both ends of the roof truss 303 to form the cantilevered ends 3045 of the roof truss 303. Simultaneously, a ridge 3033 is formed at the top of the frame 300, i.e., the highest point of the roof truss 303. Figure 11 As shown.

[0060] To improve the construction efficiency of the solar power station in a sunroom, the columns 302 and horizontal tie beams can be installed and welded synchronously and alternately. The traditional construction sequence for solar power stations is to first install the columns 302, then install the roof truss 303 onto the columns 302, and finally install the horizontal tie beams. This results in low welding efficiency, and the components are relatively independent, failing to form a unified grounding environment. By adopting a synchronous and alternating installation and welding method for the columns 302 and horizontal tie beams—that is, installing one column 302 and simultaneously installing one horizontal tie beam—the installation is completed alternately, forming a unified grounding environment and improving welding efficiency. It should be noted that the horizontal tie beams are not shown in the figures. This application only improves the construction sequence of the columns 302 and horizontal tie beams to increase welding efficiency; the structural form of the horizontal tie beams can be referenced from traditional solar power stations and will not be explained further here. The horizontal beam 304 includes a first horizontal beam 3041 and a second horizontal beam 3042. The horizontal beam 304 connects to adjacent inclined beams 3032 in a direction parallel to the ridge 3033. The first horizontal beam 3041 is positioned across the entire span of the frame 300, meaning it is parallel to the ridge 3033, runs through the entire roof truss 303, and extends to both ends of the roof truss 303, forming cantilevered ends 3045. The second horizontal beam 3042 is positioned on the side span 3044 of the frame 300, meaning it is parallel to the ridge 3033 and is positioned on the inclined beams 3032 of the two triangular supports 3031 on the side of the roof truss 303. This improves the overall stability and strength of the roof truss 303 while also supporting the photovoltaic panels 500. Figure 10 and Figure 11 As shown, compared to traditional solar power stations, the false beam 3043 at the cantilever end 3045 is eliminated, reducing the construction difficulty of the roof truss 303 and improving the construction efficiency of the photovoltaic solar power station. Of course, the second horizontal beam 3042 can be added according to the actual needs of the solar power station, such as the span requirements of the frame 300. Figure 11 As shown, two second horizontal beams 3042 are set at intervals on the side spans 3044 on both sides of the frame 300. Three or four beams can also be set to meet the strength and stability requirements of the sunroom power station.

[0061] Furthermore, such as Figure 12As shown, the drainage trough 400 includes a first longitudinal water trough 404, a first transverse water trough 403, and a water collection trough 402. The first transverse water trough 403 is located at the ridge 3033 of the roof truss 303, and the water collection trough 402 is located at the eaves 3034 of the roof truss 303, i.e., the lowest point of the roof truss 303. The first longitudinal water trough 404 is located at the cantilevered end 3045 of the roof truss 303, with its first end connected to the first transverse water trough 403 and its second end connected to the water collection trough 402, so that rainwater in the first transverse water trough 403 flows along the first longitudinal water trough 404 into the water collection trough 402 and is discharged through a drainage hole in the water collection trough 402.

[0062] Simultaneously, a second transverse water trough 405 is provided between the first transverse water trough 403 and the water collection trough 402. The second transverse water trough 405 is located between adjacent first horizontal beams 3041 and is connected to the first longitudinal water trough 404. Furthermore, multiple second longitudinal water troughs 406 are provided between the first longitudinal water troughs 404 at both ends of the roof truss 303. The second longitudinal water troughs 406 are located between adjacent tripods 3031 and overlap the horizontal beams 304. The second longitudinal water troughs 406 are connected to the second transverse water trough 405 and the water collection trough 402 respectively. Figure 10 and Figure 12 As shown, compared with the drainage structure of traditional solar power plants, the longitudinal main water channel 401 is eliminated, simplifying the drainage structure without adding extra components, reducing construction difficulty, and improving the construction efficiency of the photovoltaic solar power plant. It should be noted that the first transverse water channel 403, the second transverse water channel 405, and the second longitudinal water channel 406 are all made of U-shaped steel. Furthermore, the first transverse water channel 403 and the second transverse water channel 405 are respectively provided with support parts to facilitate connection to the second longitudinal water channel 406, thereby increasing the contact area between the end of the second longitudinal water channel 406 and the first transverse water channel 403 and the second transverse water channel 405, ensuring the reliability of the connection between the end of the second longitudinal water channel 406 and the first transverse water channel 403 and the second transverse water channel 405.

[0063] Furthermore, such as Figure 13 and Figure 14As shown, in one specific embodiment, the first longitudinal water tank 404 is provided with a first water storage portion 4041 and a first water inlet 4042. A first transverse water tank 403 and a second transverse water tank 405 extend into the first water inlet 4042 of the first longitudinal water tank 404, so that rainwater flows into the first water storage portion 4041 of the first longitudinal water tank 404 along the first transverse water tank 403 and the second transverse water tank 405. Simultaneously, a horizontal beam 304 extends into the first water inlet 4042 of the first longitudinal water tank 404, and the first longitudinal water tank 404 is fixed to the end of the horizontal beam 304 with self-tapping screws. Specifically, as... Figure 14 As shown, the first longitudinal water tank 404 is an edged water tank, and the edged water tank includes a first bottom plate 4043 and a top plate 4044. The first bottom plate 4043 and the top plate 4044 are connected by a first side plate 4045. A support plate 4046 is provided on the first bottom plate 4043 so that the support plate 4046, the first bottom plate 4043 and the first side plate 4045 surround to form a first water storage part 4041. An overlapping part 4048 is provided on the support plate 4046 so that the first transverse water tank 403 and the second transverse water tank 405 extend into the first water inlet 4042 of the first longitudinal water tank 404 and are connected and fixed to the first longitudinal water tank 404. Meanwhile, a first water inlet 4042 is formed between the support plate 4046 and the top plate 4044, and the support plate 4046 is inclined on the first bottom plate 4043 so that a guide portion 4047 is formed on the support plate 4046 to facilitate rainwater flow into the first water storage section 4041. It should be noted that the first longitudinal water trough 404 can be formed by directly bending a steel plate, or by splicing steel plates by welding.

[0064] Furthermore, such as Figure 13As shown, in one specific embodiment, the water collection tank 402 includes a second base plate 4021 and second side plates 4022 disposed on both sides of the second base plate 4021. The second base plate 4021 and the second side plates 4022 on both sides of the second base plate 4021 form a second water storage section 4023. For ease of understanding, the two opposite sides of the water collection tank 402 are defined as the first side and the second side, respectively, and the two second side plates 4022 are located on the first side and the second side of the water collection tank 402, respectively. The height of the second side plate 4022 on the first side of the water collection trough 402 is less than the height of the second side plate 4022 on the second side of the water collection trough 402, so that a second water inlet 4024 is formed on the first side of the water collection trough 402. The second end of the first longitudinal water channel 404 extends into the second water inlet 4024 to allow rainwater to flow into the second water storage section 4023 along the first longitudinal water channel 404. A bend is provided on the second side plate 4022 on the first side of the water collection trough 402 to facilitate the connection and fixation of the first longitudinal water channel 404 and the second longitudinal water channel 406 to the water collection trough 402. At the same time, a drain hole is provided on the second base plate 4021 and is connected to the downpipe located below the second base plate 4021 to discharge the rainwater flowing into the water collection trough 402 to the roof through the downpipe. It should be noted that the downpipe is made of PVC pipe and is fixed to the column 302 by clamps and connected to the ground drainage pipe.

[0065] Step S104: Install photovoltaic panels;

[0066] like Figure 13 As shown, photovoltaic panels 500 are installed on horizontal beams 304, with the upper surface of photovoltaic panels 500 flush with the opening of drainage channels 400, so that rainwater on photovoltaic panels 500 can flow into drainage channels 400. Specifically, the edges of the first row of photovoltaic panels 500 are first leveled from one end of the roof truss 303 to the other end. After the first row of photovoltaic panels 500 is neatly laid on the horizontal beams 304, the remaining photovoltaic panels 500 are installed flush with the first row of photovoltaic panels 500, while ensuring that the upper surface of the photovoltaic panels 500 is flush with the opening of the second longitudinal water channel 406, so that rainwater on the surface of photovoltaic panels 500 flows into the second longitudinal water channel 406, and then into the collection tank 402 through the second transverse water channel 405 and the first longitudinal water channel 404, and finally discharged from the roof through the downpipe.

[0067] The construction method for the solar power station disclosed in this invention, in step S101 (base installation), uses a positioning tool 100 to quickly mark the base hole positions at the base centerline 104. By aligning the mounting holes 3022 of the base 3021 with the base hole positions and fixing them with expansion bolts, the base 3021 can be quickly installed at the base centerline 104, improving the installation efficiency of the base 3021. Simultaneously, in step S102 (column positioning), a column marking tool 200 can quickly mark the four corners of the column 302 on the base 3021 sequentially, unaffected by installation errors of the base 3021, and with good fault tolerance. Even if the base 3021 is installed crookedly, the positioning of the column marking tool 200 with the base centerline 104 ensures that the column 302 is installed on the same horizontal line, reducing repetitive construction processes and improving the efficiency and accuracy of column 302 positioning. By using the positioning tool 100 and the column marking tool 200, the efficiency of component positioning and installation is improved, thereby increasing the construction efficiency of the solar power station. Furthermore, by eliminating the installation of the false beam 3043 and the longitudinal main water channel 401, and replacing the decorative steel beam 301 with the first longitudinal water channel 404, not only is the low drainage efficiency problem solved, but the drainage structure is also simplified by eliminating the longitudinal main water channel 401 without adding additional components. Simultaneously, the addition of a second horizontal beam 3042 at the side span 3044 not only solves the problem of supporting the solar photovoltaic modules but also reduces construction difficulty and improves the construction efficiency of the solar power station.
