Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel installation technology, and in particular to a mold for quickly and accurately positioning photovoltaic panels. Background Technology

[0002] The installation of photovoltaic (PV) panels requires the initial installation of U-shaped brackets (also called support purlins). These brackets are positioned according to the dimensions specified in the drawings, consuming significant manpower, resources, and time. Furthermore, this process suffers from problems such as large errors in marking and positioning, inconsistent spacing between adjacent PV panels, uneven array arrangement, and deviations in the flatness of different PV panels. Additionally, installing and fixing individual PV panel U-shaped brackets on torque tubes makes it difficult to guarantee the installation spacing and smoothness during panel installation, necessitating subsequent adjustments to the bracket smoothness and PV panel spacing, further increasing workload and cost.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] The South African Oya Hybrid Energy Project is configured with 155MW of tracking photovoltaic (PV) power, 18×4.8MW of onshore wind power, and 94MW of battery storage. The PV field contains 274,500 flat single-axis PV modules, with panel dimensions of 2333*1134*30mm and a 10mm spacing between panels. The U-shaped brackets (support purlins) at the bottom of the PV panels come in three lengths: 1428mm, 1228mm, and 428mm, with the 428mm length accounting for over 90%. The spacing between the U-shaped brackets fixing the PV panels is 1144mm.

[0027] Each photovoltaic power generation unit consists of 4 groups and 23 panels. As the light angle changes, a transmission rod drives 4 torque tubes 11 to rotate simultaneously. The torque tubes 11 are either octagonal or hexagonal; octagonal is preferred.

[0028] Conventional installation involves marking positions according to the dimensions specified in the drawings, which consumes significant manpower, resources, and time. It also suffers from problems such as large errors in marking and positioning, inconsistent spacing between adjacent photovoltaic panels, uneven array arrangement, and deviations in the flatness of different photovoltaic panels. Furthermore, installing and fixing individual photovoltaic panel U-shaped brackets 8 on the torque tube 11 cannot guarantee the installation spacing and smoothness during photovoltaic panel installation. This necessitates subsequent adjustments to the smoothness of the U-shaped brackets 8 and the spacing between photovoltaic panels, increasing additional workload and cost.

[0029] Specific embodiments of the mold for rapid and high-precision positioning of photovoltaic panels provided by this utility model:

[0030] Please see Figure 1-9A mold for quickly and accurately positioning photovoltaic panels is constructed using 4cm × 10cm tubular square steel and a 428mm U-shaped bracket. This simple mold, easily lifted by two people, consists of two parallel 6m long longitudinal square steel bars 1, three 428mm long transverse square steel bars 2, and two 428mm long U-shaped steel bars 3. The U-shaped steel bars 3 can be replaced with the 428mm long transverse square steel bars 2. The transverse square steel bars 2 and U-shaped steel bars 3 are spaced evenly and alternately, connecting the two longitudinal square steel bars 1. Each connection point is secured with one or two M8 fastening screws 4, and nuts are used for reinforcement if necessary, forming a rectangular frame-like mold skeleton structure. The transverse square steel bars 2 and U-shaped steel bars 3 act as crossbeams connecting the two longitudinal square steel bars 1. The ends of the transverse square steel bars 2 and U-shaped steel bars 3 each have fastening screws 4 that connect to the longitudinal square steel bars 1. When using nuts with the fastening screws 4, through holes corresponding to the fastening screws 4 are made in the lower wall of the longitudinal square steel bars 1 so that the nuts can be connected and fitted with the fastening screws 4. The transverse square steel 2 and U-shaped steel 3 are connected to the upper side of the longitudinal square steel 1, with both ends flush with the outer surface of the longitudinal square steel 1. The three transverse square steel 2 are located at both ends and the middle of the longitudinal square steel 1, and the two U-shaped steel 3 are located between the three transverse square steel 2. The U-shaped steel 3 has sharp edges and is easily scratched, so the crossbeams at both ends must be made of transverse square steel 2.

[0031] In addition, according to the positioning standard of the photovoltaic panel U-shaped bracket 8, M8 flat-head positioning bolts 5 are evenly installed on the longitudinal square steel 1. The exposed length of the bottom of the positioning bolt 5 is 1cm to ensure that the exposed part matches the reserved bolt hole 9 for fixing the photovoltaic panel on the U-shaped bracket 8, so as to avoid large deviation between the diameter of the positioning bolt 5 and the reserved bolt hole 9, which would lead to large fixing errors. The positioning bolts 5 on the two longitudinal square steels 1 correspond to each other.

[0032] The positioning bolt 5 passes through the lower wall of the longitudinal square steel 1; the upper wall of the longitudinal square steel 1 has an upper hole 7 corresponding to the positioning bolt 5, facilitating the insertion of the positioning bolt 5 into the longitudinal square steel 1. A liner nut 6 is connected to the lower part of the positioning bolt 5. Tightening the liner nut 6 causes it to fit against the lower side of the longitudinal square steel 1, thus fixing the positioning bolt 5. In this embodiment, the length of the bottom of the positioning bolt 5 protruding from the lower side of the liner nut 6 is 1cm. The first positioning bolt 5 is at least 5cm from the edge of the mold, generally between 5-10cm.

[0033] This design takes "movable mold + precise positioning" as its core concept. According to the installation spacing requirements of photovoltaic panels, multiple sets of positioning bolts 5 for U-shaped brackets 8 for photovoltaic panel installation are precisely implanted into the fixed mold. The spacing between adjacent positioning bolts 5 strictly matches the spacing standard for photovoltaic panel installation.

[0034] During the installation of the U-shaped brackets 8, the distance positioning of the first U-shaped bracket 8 is completed. The positioning bolt 5 at the end of the mold cooperates with the bolt hole 9 on one side of the U-shaped bracket 8 for positioning. Moving the subsequent U-shaped brackets 8 allows the positioning bolt 5 to automatically position other U-shaped brackets 8 (for ease of manual handling, the mold typically fixes 5-6 U-shaped brackets 8 at a time; in this embodiment, 6 are fixed). The bolt holes 9 on the same side of all U-shaped brackets 8 cooperate with the positioning bolt 5, thereby quickly and accurately replicating the standard spacing, parallelism between brackets, and flatness of all brackets. At the same time, the flatness of the mold ensures that the U-shaped brackets 8 are installed in one go and directly fixed to the torque tube 11. Subsequent U-shaped brackets 8 are then installed on the same torque tube 11 sequentially. After completing the same torque tube 11, the process moves to the next torque tube 11.

[0035] After the U-shaped bracket 8 is fixed, the photovoltaic panels are installed and fixed in place in sequence without further adjustments or corrections; this lays the foundation for ensuring power generation efficiency and reducing operation and maintenance costs.

[0036] The simplified mold allows for convenient on-site operation and easy transport and relocation. After fixing the first U-shaped bracket 8, the installation points for the subsequent five photovoltaic panel U-shaped brackets 8 can be pre-positioned simultaneously. The fixed U-shaped brackets 8 are evenly spaced, with an installation error within 2mm, and the success rate of installing the U-shaped brackets 8 on the first attempt reaches 100%.

[0037] The spacing accuracy of the installed photovoltaic panels is within 2mm, resulting in a smooth and aesthetically pleasing finish. There is no contact between the panels, and no readjustment is required, achieving a 100% success rate for installation. On-site personnel can focus solely on fixed tasks, truly realizing a standardized process of "one-time positioning, efficient installation of one set," achieving full coverage of standardized spacing. Significant reductions in manpower, material, and machinery costs are achieved only during the U-shaped bracket installation and photovoltaic panel installation stages. Installation efficiency is significantly improved compared to traditional methods, providing a replicable and scalable solution for large-scale photovoltaic project construction.

[0038] In this embodiment, the U-shaped bracket 8 is a U-shaped strip structure with horizontal bends on both sides; each side of the U-shaped bracket 8 has two bolt holes 9 at the bends, and each U-shaped bracket 8 has a total of four bolt holes 9. The bolt holes 9 on the same side correspond to the lower edge of the photovoltaic panel. The U-shaped bracket 8 connects two photovoltaic panels on each side and supports the photovoltaic panels, while ensuring that there is a gap between the two photovoltaic panels.

[0039] The lower walls at both ends of the U-shaped bracket 8 are provided with connection holes 10. Each U-shaped bracket 8 has two connection holes 10, corresponding to both sides of the torque tube 11. The U-shaped bracket 8 is fixed by a U-shaped rod 12, which has threads at both ends. The lower part of the U-shaped rod 12 is wrapped around the lower outer side of the torque tube 11. The two ends of the U-shaped rod 12 pass through the two connection holes 10 of the U-shaped bracket 8. Two fastening nuts 13 are threaded to both ends of the U-shaped rod 12. By tightening the fastening nuts 13, the U-shaped bracket 8 can be fixed to the upper side of the torque tube 11. In order to make the U-shaped rod 12 and the U-shaped bracket 8 stable, the lower part of the U-shaped rod 12 has a multi-section bending structure that fits against the lower sides of the torque tube 11.

[0040] The connection between the U-shaped bracket 8 and the photovoltaic panel is achieved by first installing the U-shaped bracket 8 on the torque tube 11 using a mold, and then installing the photovoltaic panel on the U-shaped bracket 8 after removing the mold. The mold in this embodiment has the following advantages: First, it improves the installation accuracy and progress of the photovoltaic panel U-shaped bracket 8, fundamentally eliminating errors from manual measurement; second, it ensures uniform spacing between adjacent panels, guaranteeing the photovoltaic panel installation quality in one go; third, it improves efficiency and avoids the need for readjustment of the U-shaped bracket 8 and photovoltaic panel after installation; and fourth, it increases the reliability during operation and maintenance, reducing maintenance costs.

[0041] By using simplified molds for positioning instead of manual experience, the installation process has been "template-based." This integrated "positioning-calibration-fixing" solution not only improves the aesthetics of the photovoltaic array but also significantly enhances the installation accuracy and construction efficiency. In the standardized construction of large-scale centralized photovoltaic power plants, this type of tool innovation should become a standard feature for promoting efficient project construction, making "millimeter-level accuracy, large-scale replication, and minimal manpower input" the norm in the industry, and driving the transformation of photovoltaic installation from "experience-driven" to "precise and efficient."

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features.
