Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, and in particular relates to a vibration reduction and holding device for balcony photovoltaic components. Background Art

[0002] One of the most important aspects of sustainable development is to address society's energy needs and use. While there is a limit to what can be done to reduce consumption, the source of energy supply can be considered. This is where renewable energy sources such as photovoltaic solar energy come in. In terms of cost and financial return, the most important component of a photovoltaic system is the photovoltaic solar module. Photovoltaic solar modules capture sunlight and convert it into electrical energy. Depending on the actual implementation of the photovoltaic system, the energy can be stored in batteries, or provide energy for DC or AC loads, or convert DC into AC and feed it back to the grid. Over the past few decades, thanks to technological advances in the photovoltaic solar industry, especially technological advances in photovoltaic solar cells, and economies of scale, the annual installed capacity of photovoltaic solar energy and the expansion of the application range of photovoltaic power generation technology have greatly increased. Compared with traditional glass photovoltaic modules, weather-resistant non-glass semi-flexible lightweight modules not only have almost the same life cycle, but also have the advantages of light weight, resistance to mechanical impact such as knocks, stain resistance, safety, no light pollution, low installation cost, and beautiful appearance. They are very suitable for vertically installed balcony photovoltaic power generation and other application scenarios with low requirements for hail impact resistance. Thanks to the improvement in efficiency and reduction in cost of photovoltaic solar cells, as well as the commercialization of weather-resistant non-glass semi-flexible lightweight module technology, the market demand for balcony photovoltaic power generation systems has also expanded year by year.

[0003] The existing balcony photovoltaic module installation method is to open several holes around the semi-flexible photovoltaic module, install metal buckles, and fix it to the horizontal handrail of the balcony railing with cable ties in the vertical direction; fix it to the vertical rod of the guardrail with cable ties in the horizontal direction, or interconnect the modules with cable ties. The advantage of the above method is that it is easy to install. However, the above installation method has the following problems:

[0004] Noise: PV panels that are fixed by tying around all sides may hit the guardrails and produce noise when blown by gusts of wind;

[0005] Reliability: Under gusty winds, PV modules may vibrate periodically, and contact with balcony railings may cause cracks in the crystalline silicon solar cells of the PV modules, damage to the welding alloy layer between the interconnection ribbons and the cell, and the risk of reliability issues such as breakage of the interconnection ribbons and hot spots, posing a serious threat to the long-term reliability of PV modules.

[0006] Therefore, a balcony photovoltaic module vibration reduction and retention device is needed to solve the risks of reliability problems such as cracks in the crystalline silicon solar cells of the photovoltaic module, damage to the welding alloy layer between the interconnection welding ribbon and the battery cell, and breakage of the interconnection welding ribbon, hot spots, etc. when the contact between the photovoltaic module and the balcony railing is blown by gusts of wind in the prior art. At the same time, it avoids the problem of the photovoltaic module hitting the guardrail and generating noise when the photovoltaic module is blown by gusts of wind. Utility Model Content

[0009] It should be noted in the solution that a first adapter plate is fixed between adjacent second adapter plates.

[0010] It is further worth noting that a mounting frame is provided on one side of the cross bar, and the cross bar and the mounting frame are connected by a cable tie.

[0011] It should be further explained that a plurality of mounting holes are provided on the top of a side surface of the first adapter plate, and the mounting holes are in the shape of straight slots.

[0012] As a preferred embodiment, there are twelve metal wire spring buckles.

[0013] As a preferred embodiment, there are twelve suction cups.

[0014] Compared with the prior art, the utility model provides a balcony photovoltaic assembly vibration reduction and holding device, which has at least the following beneficial effects:

[0015] (1) The metal wire spring buckle and suction cup can effectively reduce the amplitude of the photovoltaic module when it is vibrated by gust wind pressure, avoiding the risk of reliability problems such as cracks in the crystalline silicon solar cells of the photovoltaic module, damage to the welding alloy layer between the interconnection welding ribbon and the battery cell, and breakage of the interconnection welding ribbon and hot spots when the contact between the photovoltaic module and the balcony railing is blown by gusts of wind. At the same time, it can avoid the photovoltaic module hitting the guardrail and generating noise when the photovoltaic module is blown by gusts of wind.

[0016] (2) The photovoltaic modules can be installed on the mounting frame by setting up the mounting frame, thereby improving the adaptability of the photovoltaic modules during installation, making the given photovoltaic module size suitable for more balcony guardrails, making the installation and fixation of the micro-inverter more convenient, and making the arrangement and fixation of the module cables more neat and beautiful.

[0026] See also Figure 1-3 The utility model provides a balcony photovoltaic module vibration reduction and holding device, including a plurality of second adapter plates 101, a plurality of linearly distributed suction cups 300 are respectively adsorbed on both sides of one side of the second adapter plate 101, and the size of the suction cup 300 is Φ=50mm, H0=40mm, and H1=10mm; the suction cup 300 is made of silicone rubber, and a metal wire spring buckle 301 is movably sleeved on one end of the outer wall of the suction cup 300. The friction between the inner wall of the metal wire spring buckle 301 and the outer wall of the suction cup 300 is relatively large, so that this position is equivalent to a damper, which effectively buffers and reduces shocks to the photovoltaic module. The metal wire spring buckle 301 is made of stainless steel, Φ=0.5mm, and a cross bar 400 is fixed at one end of the three metal wire spring buckles 301.

[0027] Further as Figure 3As shown, a first adapter plate 100 is fixed between adjacent second adapter plates 101. The material of the first adapter plate 100 and the second adapter plate 101 can be PVC, UHMPE, PC, PP, GFRP, etc., preferably UHMPE. The size of the first adapter plate 100 is approximately 1200mm×210mm×6mm.

[0028] By providing the first adapter plate 100 , two adjacent second adapter plates 101 can be connected, so that the first adapter plate 100 and the second adapter plate 101 can become a whole.

[0029] Further as Figure 3 As shown, a mounting frame 200 is provided on one side of the cross bar 400, and the cross bar 400 is connected to the mounting frame 200 by a cable tie, and the number of the cross bars 400 is configured at one for every 250 to 300 mm; the size of the cross bar 400 is approximately 2000 mm×40 mm×6 mm; the material of the cross bar 400 can be selected from polyvinyl chloride (PVC), ultra-high molecular weight polyethylene (UHMWPE), polycarbonate (PC), glass fiber epoxy resin (such as FR-4, etc.), etc., preferably UHMWPE.

[0030] By providing the mounting frame 200 , the photovoltaic components can be fixed on the mounting frame 200 by means of cable ties, so that the fixing of multiple photovoltaic components is facilitated.

[0031] This solution has the following working process: when fixing the first adapter plate 100, the cable tie is passed through the installation hole 102 so that the cable tie fixes the first adapter plate 100 and the balcony railing, so that the position of the first adapter plate 100 is fixed; when installing the photovoltaic component, the photovoltaic component is fixed on the mounting frame 200 by the cable tie, so that the photovoltaic component is fixed.

[0032] The photovoltaic assembly is shock-absorbing. When the wind blows towards the photovoltaic assembly, the photovoltaic assembly is blown, causing the photovoltaic assembly to move, thereby pushing the metal wire spring buckle 301. Since the friction between the inner wall of the metal wire spring buckle 301 and the outer wall of the suction cup 300 is large, it is equivalent to a damper, so that the photovoltaic assembly can play a buffering and shock-absorbing role after being blown by the wind.

[0033] According to the above working process, it can be known that: by setting the metal wire spring buckle 301 and the suction cup 300, the amplitude of the photovoltaic module when it is vibrated by the gust wind pressure can be effectively reduced, avoiding the risk of reliability problems such as cracks in the crystalline silicon solar cells of the photovoltaic module, damage to the welding alloy layer between the interconnection welding ribbon and the battery cell, and breakage of the interconnection welding ribbon, hot spots, etc. when the contact between the photovoltaic module and the balcony railing is blown by gusts of wind. At the same time, it avoids the photovoltaic module hitting the guardrail to generate noise when the photovoltaic module is blown by gusts of wind.

[0034] By setting up the mounting frame 200, the photovoltaic module can be installed on the mounting frame 200, thereby improving the adaptability of the photovoltaic module during installation, making a given photovoltaic module size suitable for more balcony guardrails, and making the installation and fixation of the micro-inverter more convenient, and the arrangement and fixation of the component cables more neat and beautiful, while reducing the stress at the cable joints, the outlet terminals of the junction box, and the micro-inverter interfaces, thereby improving safety.

[0035] By fixing the photovoltaic assembly on the mounting frame 200 through a cable tie, the photovoltaic assembly becomes more neat and beautiful.

[0036] Further as Figure 1 As shown, a plurality of mounting holes 102 are provided on the top of one side of the first adapter plate 100, wherein L1=5±1mm, L2=55±1mm, L3=55±1mm, L4=55±1mm, L5=55±1mm, L6=55±1mm, L7=55±1mm, L8=55±1mm, and the mounting hole 102 is in the shape of a straight slot.

[0037] The first adapter plate 100 can be fixed on the vertical rod of the balcony railing through the mounting hole 102, thereby facilitating the fixing of the position of the photovoltaic module.

[0038] Further as Figure 3 As shown, there are twelve metal wire spring buckles 301.

[0039] The metal wire spring buckle 301 can provide a buffer for the mounting frame 200 and thus provide a shock-absorbing effect for the photovoltaic assembly.

[0040] Further as Figure 3 As shown, there are twelve suction cups 300 .

[0041] By providing the suction cup 300 , the cross bar 400 can be connected to the second adapter plate 101 , thereby facilitating the connection of the mounting frame 200 to the first adapter plate 100 .

[0042] In summary: when fixing the first adapter plate 100, the cable tie is passed through the mounting hole 102 so that the cable tie fixes the first adapter plate 100 to the balcony railing, so that the position of the first adapter plate 100 is fixed; when installing the photovoltaic component, the photovoltaic component is fixed to the mounting frame 200 by the cable tie so that the photovoltaic component is fixed.

[0043] The photovoltaic assembly is shock-absorbing. When the wind blows towards the photovoltaic assembly, the photovoltaic assembly is blown, causing the photovoltaic assembly to move, thereby pushing the metal wire spring buckle 301. Since the friction between the inner wall of the metal wire spring buckle 301 and the outer wall of the suction cup 300 is large, it is equivalent to a damper, so that the photovoltaic assembly can play a buffering and shock-absorbing role after being blown by the wind.

[0044] Both the suction cup 300 and the metal wire spring buckle 301 can be purchased from the market, and are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
