Description

Technical Field

[0001] This invention relates to solar photovoltaic power generation technology, and more particularly to a snap-fit ​​fixing support system for solar photovoltaic panels. Background Technology

[0002] Solar energy is the energy produced by the continuous nuclear fusion reactions inside or on the surface of the sun, particularly in sunspots. Solar energy boasts advantages such as abundant resources, long lifespan, wide distribution, safety, cleanliness, and reliable technology. Because it can be converted into various other forms of energy, its applications are extremely broad. Obtaining electricity from solar energy requires photovoltaic conversion using solar cells.

[0003] In most existing solar photovoltaic (PV) panels, the panels are first installed inside an aluminum frame, and then the aluminum frame is connected to the base with bolts. The aluminum frame is very expensive to form and is prone to deformation. In addition, the PV panels are quite heavy, and after long-term use, the PV panels may fall off under the influence of wind and rain.

[0004] To address the stability issues of aluminum frames, existing technologies have proposed replacing them with steel frames. When connecting the steel frame to the base, a connecting edge extending beyond the steel frame's outline is formed to facilitate installation, allowing bolts to be inserted without interference from the steel frame itself. However, this connecting edge extending beyond the steel frame's outline contributes nothing to the overall strength of the steel frame; it merely serves a connecting function. The extension significantly increases the manufacturing cost of the steel frame. Furthermore, accommodating this connecting edge structure increases the overall size of the steel frame, further increasing material costs. Additionally, this bolt-through-hole installation structure is extremely inconvenient during on-site installation, impacting installation efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a snap-fit ​​fixing support system for solar photovoltaic panels that is simple in structure, easy to install, and can achieve small frame size and lightweight, thereby reducing manufacturing costs, transportation costs and material costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A snap-fit ​​fixing support system for solar photovoltaic panels includes a photovoltaic panel unit, a support base, and snap-fit ​​fasteners. The photovoltaic panel unit includes a photovoltaic panel and a photovoltaic frame covering the edge of the photovoltaic panel. The support base has a support edge for supporting the photovoltaic frame. The photovoltaic frame is supported on the support edge. The snap-fit ​​fasteners press the photovoltaic frame together and fasten it to the support base.

[0008] As a further improvement to the above technical solution:

[0009] The fastener includes a pressure plate with a fastening edge. The pressure plate presses against the photovoltaic frame, and the fastening edge fastens to the support base.

[0010] The bearing edge is provided with a buckle hole, and the buckling edge is fastened to the buckle hole.

[0011] A fastening platform is installed on the bearing edge, and the fastening member presses the photovoltaic frame and fastens it to the fastening platform.

[0012] The fastener is bolted to the bearing side, and the fastener includes a pressure plate with a fastening hole for engaging with the fastener.

[0013] A fastening platform is formed at the middle position on the bearing edge, and the fastening member presses the photovoltaic frame and fastens it to the fastening platform.

[0014] The fastener includes a pressure plate with a fastening groove. The pressure plate presses against the photovoltaic frame, and the fastening groove is fastened to the fastening platform.

[0015] The fastening platform has fastening cavities formed on both sides, and the fastening member presses the photovoltaic frame and fastens to the corresponding fastening cavity.

[0016] The fastener includes a pressure plate with a snap-fit ​​edge formed on its side. The pressure plate presses against the photovoltaic frame, and the snap-fit ​​edge snaps into the corresponding snap-fit ​​cavity.

[0017] The two sides of the mounting platform are formed with recessed grooves, and fastening parts are installed in the recessed grooves. The pressing fasteners press the photovoltaic frame and fasten it to the corresponding fastening parts on the side.

[0018] The fastener includes a pressure plate with a snap-fit ​​edge formed on its side. The pressure plate presses against the photovoltaic frame, and the snap-fit ​​edge snaps into the corresponding snap-fit ​​groove.

[0019] The fastener has fastening holes on both sides of the fastening platform. The fastener presses against the photovoltaic frame and fastens with the corresponding fastening holes.

[0020] The fastener includes a pressure plate with a snap-fit ​​edge formed on its side. The pressure plate presses against the photovoltaic frame, and the snap-fit ​​edge snaps into the snap-fit ​​hole on the corresponding side.

[0021] The fastening platform is provided with a fastening groove, and the fastening member includes a pressure plate with a fastening edge. The fastening member presses the photovoltaic frame tightly, and the fastening edge and the fastening groove fasten to each other.

[0022] The fastener is installed on the bearing side by bolts.

[0023] Compared with the prior art, the advantages of the present invention are as follows:

[0024] The present invention provides a snap-fit ​​fixing support system for solar photovoltaic panels, comprising a photovoltaic panel unit, a support base, and snap-fit ​​fasteners. The photovoltaic panel unit includes a photovoltaic panel and a photovoltaic frame covering the edges of the photovoltaic panel. The support base has a support edge for supporting the photovoltaic frame, which is supported on the support edge. The snap-fit ​​fasteners press the photovoltaic frame together and fasten to the support base. During installation, the support base is first erected and fixed. Each photovoltaic frame is then inserted and covered around the perimeter of the photovoltaic panel to form a photovoltaic panel unit. The photovoltaic frame of the photovoltaic panel unit is then supported on the support edge of the support base. Finally, the snap-fit ​​fasteners press the photovoltaic frame together, simultaneously fastening the snap-fit ​​fasteners to the support base, thereby achieving the installation and fixing of the photovoltaic panel unit. Compared to traditional structures, this invention utilizes snap-fit ​​fasteners to simultaneously clamp the photovoltaic frame and fasten it to the support base, eliminating the need for bolt-through-hole installation structures and greatly improving installation convenience and efficiency. Since clamping and fastening are achieved simultaneously through snap-fit ​​fasteners, there is no need for connecting edges extending beyond the steel frame outline. This allows for a smaller overall size of the photovoltaic frame, achieving lightweighting of the photovoltaic frame and photovoltaic panel unit assembly, reducing manufacturing and transportation costs, and also saving on material costs.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Example 1:

[0046] Figures 1 to 3This invention illustrates a first embodiment of a snap-fit ​​fixing support system for solar photovoltaic panels, comprising a photovoltaic panel unit 1, a support base 2, and a snap-fit ​​member 3. The photovoltaic panel unit 1 includes a photovoltaic panel 11 and a photovoltaic frame 12 covering the edge of the photovoltaic panel 11. The support base 2 has a support edge 21 for supporting the photovoltaic frame 12, which is supported on the support edge 21. The snap-fit ​​member 3 presses the photovoltaic frame 12 and engages with the support base 2. During installation, the support base 2 is first erected and fixed. Each photovoltaic frame 12 is then inserted and covered around the perimeter of the photovoltaic panel 11 to form a photovoltaic panel unit 1. The photovoltaic frame 12 of the photovoltaic panel unit 1 is then supported on the support edge 21 of the support base 2. Finally, the snap-fit ​​member 3 presses the photovoltaic frame 12, and simultaneously engages with the support base 2, thereby achieving the installation and fixing of the photovoltaic panel unit 1. Compared to traditional structures, this invention utilizes the snap fastener 3 to simultaneously press the photovoltaic frame 12 and fasten it to the support base 2, eliminating the need for a bolt-through-hole installation structure, thus greatly improving the convenience and efficiency of installation. Since pressing and fastening are achieved simultaneously through the snap fastener 3, there is no need for a connecting edge extending beyond the outline of the steel frame. This allows the overall size of the photovoltaic frame 12 to be made smaller, achieving lightweighting of the photovoltaic frame 12 and the photovoltaic panel unit 1 frame, reducing manufacturing and transportation costs, and also saving on material costs.

[0047] In this embodiment, the clamping member 3 includes a clamping plate 31 with a fastening edge 311. The clamping plate 31 clamps the photovoltaic frame 12, and the fastening edge 311 fastens to the support base 2. In this structure, the clamping plate 31 is used to clamp the photovoltaic frame 12, and the fastening edge 311 fastens to the support base 2, thereby achieving both clamping and fastening simultaneously. This eliminates the need for a connecting edge extending beyond the outline of the steel frame. On the one hand, this allows for a smaller overall size of the photovoltaic frame 12, achieving lightweighting of the photovoltaic frame 12 and the photovoltaic panel unit 1 frame, reducing manufacturing and transportation costs, and also saving on material costs.

[0048] In this embodiment, a buckle hole 211 is provided on the bearing edge 21, and the buckle edge 311 is fastened to the buckle hole 211. In this structure, the buckle edge 311 is squeezed into the buckle hole 211 and then fastened in the opposite direction, which is simple and reliable.

This eliminates the need for a connecting edge extending beyond the steel frame outline. On the one hand, this allows for a smaller overall size of the photovoltaic frame 12, achieving lightweighting of the photovoltaic frame 12 and the photovoltaic panel unit 1 frame assembly, reducing manufacturing and transportation costs; on the other hand, it also saves on material costs.

[0054] In this embodiment, the fastener 3 includes a pressure plate 31 with a fastening groove 313.

The snap-fit ​​members 3 press against the photovoltaic frame 12 and simultaneously engage with the corresponding snap-fit ​​members 23, thus achieving both pressing and engagement simultaneously. This eliminates the need for connecting edges extending beyond the steel frame outline. On the one hand, this allows for a smaller overall size of the photovoltaic frame 12, achieving lightweighting of the photovoltaic frame 12 and the photovoltaic panel unit 1 frame, reducing manufacturing and transportation costs, and also saving on material costs.
