Description

Technical Field

[0001] This utility model relates to the field of distributed photovoltaic installation technology, specifically a distributed photovoltaic fixing component. Background Technology

[0002] Currently, global demand for clean energy is growing rapidly. Rooftop distributed photovoltaic (PV) power generation systems have become a popular green energy solution due to their ability to efficiently utilize idle rooftop space, and are widely used in various types of buildings. Among these systems, PV mounting hardware plays a crucial role in the stable installation of PV panels and the efficient operation of the system; its performance directly affects the stability, safety, and installation efficiency of the power generation system.

[0003] Taking the rooftop distributed photovoltaic fixing components disclosed in CN 221929691 U as an example, there are still problems in actual installation: during installation, after the construction workers set up the support frame, they need to adjust the position and height of the U-shaped block, and then install the auxiliary plate, limit sleeve, side connector, first U-shaped plate and other components in sequence. The operation is cumbersome and requires a lot of manpower and time, which greatly reduces the overall installation efficiency.

[0004] Moreover, the fastener has obvious shortcomings in protecting the photovoltaic panel: even when the photovoltaic panel is fixed with the first pressing plate, the second pressing plate and the auxiliary plate, most of its side is still exposed. In the complex outdoor environment, the side of the photovoltaic panel is susceptible to wind and sand erosion, rain erosion and external impact. This not only accelerates the aging of the photovoltaic panel and affects the power generation efficiency, but may also cause electrical safety hazards and reduce the service life and reliability of the photovoltaic system.

[0005] Therefore, it is imperative to develop a new type of distributed photovoltaic fixing component that is easy and efficient to install and has good protective effects. This is of great significance for promoting the wider and safer application of rooftop distributed photovoltaic power generation systems and improving the overall benefits of clean energy projects.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Example 1

[0024] Please see Figure 1-4A distributed photovoltaic fixing component includes a pair of mounting plates 1 arranged side by side and multiple fixing units 2 mounted on the two mounting plates 1. The mounting plates 1 have a U-shaped structure, and multiple mounting holes are evenly spaced on the bottom surface of the mounting plates 1. A guide rail 4 is fixedly mounted on the top surface of the mounting plates 1. Each fixing unit 2 includes a pair of engaging parts 3 and an adjustment module for adjusting the distance between the two engaging parts 3. The engaging parts 3 have a U-shaped structure, and slide rails adapted to the guide rail 4 are symmetrically arranged on the bottom surface of the engaging parts 3. The two engaging parts 3 are spliced ​​together to form a frame for fixing photovoltaic panels 5. The four corners of the engaging parts 3 are also respectively provided with first... The first baffle 6 and the second baffle 7 are positioned between the photovoltaic panel 5 and the first baffle 6 and the second baffle 7. The guide rail 4 on the top surface of the mounting plate 1 provides precise guidance for the installation and position adjustment of the fixing unit 2, making it convenient for construction personnel to flexibly adjust the fixing unit 2 according to the layout of the photovoltaic panel 5, thus improving installation efficiency. The frame formed by splicing a pair of U-shaped clips 3, together with the adjustment module, can firmly clamp the photovoltaic panel 5 from multiple directions, which has the advantages of high installation efficiency and good protection effect. The setting of the first baffle 6 and the second baffle 7 at the four corners can limit the upper and lower surfaces of the photovoltaic panel 5, further improving the installation effect.

[0025] The first baffle 6 and the second baffle 7 are both triangular structures, and the area of ​​the first baffle 6 is smaller than that of the second baffle 7. With this arrangement, when installing the photovoltaic panel 5, the photovoltaic panel 5 can be placed on the four second baffles 7 first. As the distance between the two locking parts 3 gradually decreases, the first baffle 6 can move to the top surface of the photovoltaic panel 5, which facilitates the installation of the photovoltaic panel 5.

[0026] In addition, a pair of positioning bolts 8 are symmetrically threaded on one of the snap-fit ​​parts 3. After the photovoltaic panel 5 is installed, the position of the fixed unit 2 can be fixed by screwing the positioning bolts 8.

[0027] Specifically, the adjustment module includes a connecting rod 9 symmetrically arranged between two engaging parts 3. The connecting rod 9 has a hexagonal cross-section, and screws 10 with opposite thread directions are installed at both ends of the connecting rod 9. Screw sleeves 11 are installed on the screws 10 and are fitted with them. The screw sleeves 11 are fixedly embedded on the end face of the engaging parts 3. The hexagonal cross-section of the connecting rod 9 allows the construction personnel to rotate it with tools, thereby driving the screws 10 with opposite thread directions to rotate synchronously. Since the screws 10 and screw sleeves 11 cooperate and the screw sleeves 11 are fixed on the end face of the engaging parts 3, the screws 10 can accurately adjust the distance between the two engaging parts 3 when they rotate, thereby fixing the photovoltaic panel 5 placed between the two engaging parts 3. At the same time, it can also adapt to photovoltaic panels 5 of different sizes, enhancing the versatility and applicability of the fixing components.

[0028] In addition, the adjustment module also includes a guide rod 12, which is arranged in parallel with the connecting rod 9. One end of the guide rod 12 is fixedly installed on the end face of one of the locking parts 3, and the other end is movably inserted into the end face of the other locking part 3. The rod provides a stable and reliable guide for the relative movement of the two locking parts 3 during the adjustment of the spacing, ensuring that the locking parts 3 move smoothly and without deviation, making the adjustment process more precise and smooth, and improving the stability and convenience of the fixing part adjustment operation.

[0029] Example 2

[0030] This embodiment is an improvement on embodiment 1, specifically as follows:

[0031] Please see Figure 3 The locking component 3 includes two symmetrically arranged L-shaped fixing plates 13 and an insert plate 14 disposed between the two L-shaped fixing plates 13. One end of the insert plate 14 is fixedly connected to one of the fixing plates 13, and the other end is movably inserted into the end face of the other fixing plate 13. This arrangement further increases the flexibility of the locking component 3 in size adjustment and improves the adaptability of the locking component 3 to photovoltaic panels 5 of different specifications.

[0032] In addition, a limiting rod 15 is fixedly provided on the side of the insert plate 14, and a limiting hole 16 is provided on the side of the fixing plate 13 for the limiting rod 15 to slide and adapt. The limiting rod 15 and the limiting hole 16 cooperate with each other, and when adjusting the distance between the two fixing plates 13, the insert plate 14 can be effectively prevented from moving excessively or falling out, ensuring that the structure of the locking part 3 remains stable at all times, so that the locking part 3 can work safely and reliably during the adjustment process.

[0033] Working principle:

[0034] When installing distributed photovoltaic (PV) mounting components, firstly, based on the installation foundation structure, fix a pair of mounting plates 1 in appropriate positions using the mounting holes on the bottom surface of the mounting plate 1. Then, slide multiple fixing units 2 sequentially onto the two mounting plates 1. When fixing the PV panel 5, first place the PV panel 5 between two locking pieces 3. Four second baffles 7 provide support for the PV panel 5. Then, the construction personnel use tools to rotate and adjust the connecting rod 9 in the module. By utilizing the cooperation between the screws 10 and the screw sleeves 11 with opposite threads at both ends of the connecting rod 9, the spacing between the two locking pieces 3 is adjusted. During this process, the guide rod 12 ensures that the clamping component 3 moves smoothly and gradually approaches and clamps the photovoltaic panel 5, ultimately achieving a stable installation of the photovoltaic panel 5. The first baffle 6 limits the top surface of the photovoltaic panel 5. Finally, the position of the fixing unit 2 is fixed by screwing the positioning bolt 8 on the clamping component 3, and the steps are repeated to install the remaining photovoltaic panels 5. Its all-round protective structure effectively protects the photovoltaic panel 5, solving the problems of cumbersome installation and insufficient protection of existing distributed photovoltaic fixing components, improving the efficiency and quality of photovoltaic panel 5 installation, and ensuring the stable operation of the distributed photovoltaic power generation system.
