Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic technology, specifically to an aluminum frame for a crush-resistant solar photovoltaic module. Background Technology

[0002] Solar photovoltaic modules, also known as solar panels, are the core devices that convert solar energy into electrical energy. They consist of multiple solar cells connected in series and parallel, and encapsulated in protective materials to form a complete power generation unit.

[0003] Aluminum frames are an important component of solar photovoltaic (PV) modules, primarily used to secure and protect the internal materials such as solar cells, glass, and backsheets. Aluminum frames are lightweight, corrosion-resistant, high-strength, and easy to process, making them a key component for structural support and installation of PV modules.

[0004] Extrusion-resistant aluminum frames for solar photovoltaic modules are special aluminum frames designed to protect photovoltaic modules from external pressure, impact, or deformation during transportation, installation, and use. These frames not only need to possess the lightweight, corrosion-resistant, and high-strength characteristics of traditional aluminum frames, but also require optimization in structural design and material selection to enhance their extrusion resistance.

[0005] Existing anti-squeeze aluminum frames for solar photovoltaic modules are mostly fixed in size, and cannot be adapted to the thickness of the solar panel to better fix solar panels of different thicknesses. Moreover, the aluminum frame is mostly a single piece of structure. If it is damaged by squeezing and needs to be replaced, the whole piece can only be replaced. This not only affects the use of the solar panel, but also leads to higher replacement costs. It cannot flexibly replace only the damaged part. Utility Model Content

[0006] To address the issues raised by existing anti-squeezing aluminum frames for solar photovoltaic modules, which are mostly fixed in size and cannot be adapted to the thickness of the solar panel, thus failing to better secure solar panels of varying thicknesses, and whose frames are mostly monolithic structures, requiring replacement of the entire frame if damaged by compression, thus affecting the use of the solar panel and increasing replacement costs, this invention provides an anti-squeezing aluminum frame for solar photovoltaic modules.

[0007] An anti-extrusion aluminum frame for a solar photovoltaic module includes an inner frame. Several dampers are fixedly installed on the outer wall of the inner frame. Each damper is detachably connected to a section of the outer frame. The sections of the outer frame are detachably connected to each other by bolt assemblies. Several sets of threaded holes are symmetrically arranged through the outer wall of the inner frame. Each threaded hole is threaded with a threaded post. A pressure block is fixedly installed at the inner end of each threaded post. Buffer friction pads are fixedly installed on the outer wall of the pressure block and the inner wall of the inner frame. Two grooves are fixedly installed on the outer wall of the inner frame. Several elastic elements are fixedly installed on the inner wall of the two grooves. A buffer plate is fixedly installed at one end of each elastic element. Both ends of the sections of the outer frame can push the buffer plate to move after being subjected to force.

[0008] Furthermore, the inner frame has an inner groove, and several pressure blocks and buffer friction pads are set inside the inner groove. The threaded post has a T-shaped structure, and the solar panel is constrained between several buffer friction pads, which are made of rubber.

[0009] Furthermore, each damper has several connecting blocks fixedly installed at one end near the outer frame. Bolts are installed sequentially through the connecting blocks and the outer wall of the outer frame. The outer ends of the bolts are threadedly connected to nuts, which can fix the damper to the outer frame.

[0010] Furthermore, both inner walls of the two grooves are fixedly equipped with sliding grooves, and the two ends of the buffer plate can move on the sliding grooves. Several outer frame sections are U-shaped structures, and their two ends can enter the grooves to push the buffer plate to move along the sliding grooves. Several elastic elements are strong rubber springs.

[0011] Furthermore, several connecting blocks are fixedly installed on the outer walls of several outer frame segments, and connecting plates are fixedly installed on both ends of the buffer plate. The bolt assembly includes bolts that penetrate the connecting blocks or connecting plates, and nuts are threadedly connected to the bolts. The two outer frame segments at the outer ends are detachably connected to the connecting plates through the bolt assembly, and the remaining several outer frame segments on the inner side are detachably connected to the connecting blocks through the bolt assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the inner frame is used to fix the solar panel and is tightened by rotating the threaded post in the threaded hole, which can flexibly fix solar panels of different thicknesses. The outer frame uses a damper and a buffer plate to achieve multiple buffers to prevent crushing force. Moreover, the multiple outer frame sections are detachable and connected. If a single outer frame is damaged, the damaged outer frame can be replaced separately without replacing the whole piece. This not only does not affect the normal use of the solar panel, but also reduces the cost of replacement. Attached Figure Description

The following will refer to the accompanying drawings. Figures 1-6 The present invention will be described in detail with reference to the embodiments.

[0025] An anti-squeezing aluminum frame for a solar photovoltaic module includes an inner frame 1. Several sets of threaded holes 5 are symmetrically arranged through the outer wall of the inner frame 1. Each threaded hole 5 is threaded with a threaded post 6. A pressure block 7 is fixedly arranged at the inner end of each threaded post 6. A buffer friction pad 8 is fixedly arranged on the outer wall of the pressure block 7 and the inner side wall of the inner frame 1. An inner groove 13 is provided inside the inner frame 1. Several pressure blocks 7 and buffer friction pads 8 are arranged inside the inner groove 13. The threaded post 6 has a T-shaped structure. The solar panel 12 is confined between several buffer friction pads 8. The buffer friction pads 8 are made of rubber.

[0026] By adjusting the rotating threaded column 6, it can be moved along the threaded hole 5, thereby fixing solar panels 12 of different thicknesses, making it highly adaptable. During installation, the solar panel 12 is placed inside the inner groove 13, and the side walls, top and bottom walls of the solar panel 12 are in contact with the buffer friction pad 8, which can play a certain role in buffering and friction, and better fix it. The pressure block 7 can press the solar panel 12 to form a fixed shape.

[0027] Several dampers 2 are fixedly installed on the outer wall of the inner frame 1. Each damper 2 is detachably connected to a section of the outer frame 3. The sections of the outer frame 3 are detachably connected to each other by bolt assembly 4. Several connecting blocks 14 are fixedly installed at one end of each damper 2 near the outer frame 3. Bolts 15 are installed through the connecting blocks 14 and the outer wall of the outer frame 3 in sequence. The outer end of the bolt 15 is threadedly connected to the nut 16, so that the damper 2 can be fixed on the outer frame 3.

[0028] During installation, through holes are fixedly provided at corresponding positions of the outer frame 3 and the connecting block 14. The bolts 15 are passed through the corresponding through holes so that each section of the outer frame 3 is mated to the corresponding damper 2. Then the nuts 16 are tightened to fix each section of the outer frame 3 to the corresponding damper 2. When the outer frame 3 is impacted, the damper 2 can reduce part of the impact force, which can buffer the outer frame 3 and protect the inner frame 1.

[0029] Several connecting blocks 14 are fixedly installed on the outer walls of several outer frame segments 3. Connecting plates 18 are fixedly installed on both ends of the buffer plate 11. The bolt assembly 4 includes bolts 15 that pass through the connecting blocks 14 or connecting plates 18. Nuts 16 are threadedly connected to bolts 15. The two outer frame segments 3 at the outer ends are detachably connected to the connecting plates 18 through the bolt assembly 4. The remaining several outer frame segments 3 on the inner side are detachably connected to the connecting blocks 14 through the bolt assembly 4.

[0030] The connecting blocks 14 on one side of the two outermost outer frame sections 3 are detachably connected to the connecting plate 18 by bolt assembly 4. The other outer frame sections 3 are all connected and fixed to each other by bolt assembly 4 to form an integral outer frame section 3. The advantage of this setting is that when one section of the outer frame section 3 is damaged and needs to be replaced, it is not necessary to replace the entire outer frame section 3, but only the damaged section needs to be replaced. This not only reduces the replacement cost, but also does not affect the daily use of the solar panel 12.

[0031] Two grooves 9 are fixedly provided on the outer wall of the inner frame 1. Several elastic elements 10 are fixedly provided on the inner wall of each groove 9. A buffer plate 11 is fixedly provided at one end of each elastic element 10. Both ends of the several outer frame segments 3 can push the buffer plate 11 to move when subjected to force. Slide grooves 17 are fixedly provided on the inner wall of each groove 9. Both ends of the buffer plate 11 can move on the slide grooves 17. The several outer frame segments 3 are all U-shaped structures, and their ends can enter the grooves 9 to push the buffer plate 11 to move along the slide grooves 17. The elastic elements 10 are strong rubber springs.

[0032] When the outer frame 3 is impacted, part of the impact force is reduced by the buffering effect of the damper 2, and another part drives the outer frame 3 to move towards the inner frame 1. When moving, the upper and lower U-shaped plates at both ends of the outer frame 3 move along the groove 9, contact and drive the buffer plate 11 to move along the slide 17, which exerts a squeezing effect on the elastic element 10. The rebound effect of the elastic element 10 can offset part of the impact force, further reduce the squeezing force, and provide better protection for the inner frame 1, that is, better protect the solar panel 12.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
