Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic components, and in particular relates to a structure for quickly laying photovoltaic components on a base surface. Background Art

[0002] Reliability, safety and low cost are requirements that any energy product must meet simultaneously. Over the past few decades, the photovoltaic industry has reduced the cost of photovoltaic products by 300 times in the past 40 years through continuous and high-quality research and development to improve photoelectric conversion efficiency, localization and automation of supply chains and production equipment. Of course, these past few decades have significantly and effectively reduced the cost of photovoltaic cells to the extreme, and both the conversion efficiency limit and the production scale effect are about to encounter bottlenecks. Therefore, photovoltaic module products still need more technological innovation.

[0003] Specifically, existing photovoltaic modules are generally transported to the construction site after processing and manufacturing, and then installed by mechanical fastening or gluing. The efficiency of on-site installation is also relatively low. Especially with the development of photovoltaic modules in large sizes, the current installation scheme will be more unsuitable and inefficient.

[0004] Although there are some photovoltaic module products that can achieve flexible bending effects in the prior art, they are all based on the technical effects of lightweight and anti-hidden crack installation, and still require a large volume during packaging and transportation.

[0005] To this end, the inventor team of the applicant decided to propose a new packaging and handling solution based on the dedicated innovative research experience in the field of photovoltaic module installation and application and the accumulated theoretical knowledge in the industry over the years to further promote the batch installation and application level of photovoltaic modules. Summary of the invention

[0006] In view of this, the purpose of the utility model is to provide a structure for quickly laying photovoltaic modules on a base surface, which can efficiently and quickly lay photovoltaic rolls on the base surface, significantly improving the batch installation efficiency of photovoltaic modules and enhancing the batch installation level of photovoltaic modules.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A structure for quickly laying photovoltaic components on a base surface, wherein a laying bracket is provided on the base surface, the photovoltaic components adopt photovoltaic coils, and a limiting shaft is inserted inside the photovoltaic coils. When the photovoltaic coils are laid, the limiting shaft and the laying bracket are installed in a limiting manner.

[0009] Preferably, at least a first laying bracket body and a second laying bracket body are provided on the base surface, and the limiting axis extends outward along both ends of the photovoltaic roll to form a first extension section of the limiting axis and a second extension section of the limiting axis, and the first extension section of the limiting axis cooperates with the first laying bracket body for limiting installation, and the second extension section of the limiting axis cooperates with the second laying bracket body for limiting installation.

[0010] Preferably, the first laying support body and the second laying support body are of separate or integrated structure.

[0011] Preferably, the laying bracket is detachably mounted on the base surface.

[0012] Preferably, the laying bracket is provided with a limiting groove for limiting installation cooperation with the limiting shaft.

[0013] Preferably, a first bracket and a second bracket are fixedly installed at both ends of the limit shaft, and the limit shaft is hollow; wherein, by inserting a sling into the first bracket, the limit shaft and the second bracket, the photovoltaic roll can be quickly lifted to the base surface where the photovoltaic components are to be laid.

[0014] Preferably, the number of bending and winding turns of the photovoltaic roll is not less than 2 turns, preferably 3 turns to 300 turns, and more preferably 5 turns to 100 turns.

[0015] Preferably, after the photovoltaic rolls are laid, a photovoltaic encapsulation composite is obtained, the width of the photovoltaic encapsulation composite is in the range of 0.1-2.5 meters, and the length of the photovoltaic encapsulation composite is in the range of 0.1-150 meters.

[0016] Preferably, the curvature radius of the photovoltaic encapsulation composite in at least one direction does not exceed 25 cm, more preferably does not exceed 15 cm.

[0017] Preferably, the photovoltaic packaging composite comprises a front packaging part, a battery string layer and a back packaging part which are composited into one; wherein the front packaging part and the back packaging part do not include a rigid packaging material, and / or the battery string layer comprises a plurality of photovoltaic battery strings which are connected in series and / or in parallel and / or do not establish a direct series or parallel connection relationship, each photovoltaic battery string comprises a plurality of battery cells which are connected in series and / or in parallel, and the battery cells are preferably made of crystalline silicon wafers or amorphous silicon wafers; the battery cells are made of whole wafers or slices; the battery string layer is in a horizontal shape or a vertical shape

[0018] This application breaks through the product form of photovoltaic modules in the prior art, and proposes to bend and roll up the photovoltaic modules into a roll, thereby realizing a new product form of rolled-up photovoltaic modules (that is, photovoltaic rolls), which greatly improves the packaging and transportation efficiency of photovoltaic modules and saves packaging and transportation costs. Specifically, when packaging the photovoltaic rolls, the photovoltaic rolls are directly installed inside the packaging box, which significantly saves the packaging and transportation volume occupied by the photovoltaic modules, simplifies the packaging structure, and reduces packaging and transportation costs.

[0019] The present application further proposes a structure for rapid laying of photovoltaic modules on a base surface. By arranging a laying bracket on the base surface, a limiting axis is inserted inside the photovoltaic roll. When laying the photovoltaic roll, the limiting axis of the photovoltaic roll is matched with the limiting installation of the laying bracket. The photovoltaic roll can be laid on the base surface efficiently and quickly, which significantly improves the efficiency of batch installation of photovoltaic modules and improves the batch installation level of photovoltaic modules.

[0020] In addition, since the photovoltaic roll (i.e., the rollable photovoltaic packaging composite) provided by the present application has excellent rollability and a curvature radius preferably not exceeding 25 cm, it has more performance advantages over traditional glass-encapsulated photovoltaic modules, mainly including:

[0021] Anti-hidden cracking: To a large extent, it avoids the risk of hidden cracking of photovoltaic modules during the manufacturing process, transportation and installation;

[0022] Higher conversion efficiency: The ability to adapt to different shapes and surfaces also helps improve the response to low-light environments, thereby improving light conversion efficiency.

[0023] Optical performance advantages: It can better adapt to changes in the incident angle of light, thereby improving the light absorption rate and is expected to improve the photoelectric conversion efficiency.

[0024] Anti-loss and fatigue performance: When used in a bent or curled state, it can maintain relatively high anti-loss and anti-fatigue performance compared to rigid components, thus extending the life of photovoltaic components.

[0025] Vibration and shock resistance: It has relatively better tolerance to vibration and shock, especially in some environments that need to withstand vibration or shock, such as mobile equipment, transportation, etc. BRIEF DESCRIPTION OF THE DRAWINGS
