Description

Technical Field

[0001] This application relates to the field of solar panel technology, and more particularly to an auxiliary device for stacking solar panels. Background Technology

[0002] In the renewable energy sector, the large-scale application of solar panels relies on an efficient logistics and transportation system. Currently, long-distance transportation of solar panel modules typically utilizes standardized containers as carriers, maximizing space utilization through optimized arrangement. However, during transportation, the solar panel modules within the container are prone to relative displacement due to factors such as vibrations from the transport vehicle, changes in acceleration, and wave loads during sea transport. This displacement not only leads to direct collisions at the edges of adjacent modules but also causes gradual wear of the surface protective coating due to continuous micro-movements, ultimately affecting the product's appearance quality and photoelectric conversion efficiency.

[0003] To address the aforementioned issues, existing technologies typically employ flexible restraint devices to physically constrain stacked or side-by-side solar panels. These solutions establish temporary connections between modules using elastic ropes or straps, utilizing friction to limit relative movement. However, practical experience shows that such restraint devices have significant limitations: firstly, stress concentration easily occurs at the contact area between the rope-type restraints and the module frame, potentially causing fatigue damage to the frame material under continuous vibration; secondly, a restraint mechanism relying solely on friction cannot eliminate micron-level relative slippage, and long-term accumulation will still lead to irreversible wear of the surface protective layer. Furthermore, the installation and disassembly of existing restraint devices require manual assistance, creating an efficiency bottleneck in large-scale transportation scenarios.

[0004] Therefore, there is an urgent need in this field for a solution that can effectively limit the relative displacement of components during transportation and avoid additional damage caused by traditional restraint methods, so as to meet the dual requirements of transportation safety and operational efficiency.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0040] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0041] Currently, long-distance transportation of solar panels mainly relies on standardized containers as carriers, optimizing component arrangement to improve space utilization and reduce transportation costs. However, in actual transportation, the solar panel components inside the container are highly susceptible to relative displacement due to the bumps and vibrations of road transport, the acceleration variations of rail transport, the wave loads of sea transport, and the complex conditions of multimodal transport. This displacement not only leads to direct collisions between the edges of adjacent components, causing mechanical damage, but also causes gradual wear of the surface protective coating due to long-term micro-friction, thus affecting the appearance quality, structural strength, and long-term photoelectric conversion efficiency of the solar panel, and may even cause potential defects such as microcracks, reducing product lifespan.

[0042] Existing technologies typically employ flexible restraint devices to physically constrain stacked or side-by-side solar panels, such as elastic ropes, nylon webbing, or adjustable straps. These solutions establish temporary connections between modules, utilizing friction and preload to limit the relative movement of the solar panels, thus reducing displacement risks during transportation to some extent. However, practical experience shows that these restraint devices have several technical limitations: First, localized stress concentrations easily form at the contact area between the ropes or webbing and the solar panel frame, potentially leading to fatigue damage to the frame material and even structural deformation under long-term vibration conditions. Second, because flexible restraints rely entirely on frictional resistance, they cannot completely eliminate micron-level relative slippage, and long-term accumulation can still cause irreversible wear on the surface protective layer, affecting product performance. Furthermore, the installation and disassembly of existing restraint devices are highly dependent on manual operation, which is not only inefficient in large-scale transportation scenarios but also suffers from poor operational consistency and difficulty in precisely controlling tightness, failing to meet the stringent requirements of efficient logistics in the modern photovoltaic industry.

[0043] Therefore, there is an urgent need in this field for an innovative solar panel transportation and securing solution that can effectively overcome the additional damage risks associated with traditional restraint methods while ensuring the safety of the components during transportation, and significantly improve loading and unloading efficiency. An ideal solution should possess adaptive constraint capabilities, effectively suppressing macroscopic displacement during transportation while buffering the effects of micro-vibrations, avoiding stress concentration and frictional wear, thereby achieving higher reliability and economy in large-scale transportation scenarios.

[0044] Based on the above problems, this application provides the following implementation method.

[0045] See Figure 1 , 2As can be seen from 3, this embodiment provides an auxiliary device for stacking solar panels, wherein the device is set on the base plate of the solar panel and consists of four mounting connection components 100 mounted on the base plate of the solar panel. The four mounting connection components 100 are respectively set at the four corners of the solar panel. The mounting connection components 100 are provided with a first through hole 110 and a plurality of second through holes 120 along the horizontal direction.

[0046] The first through hole 110 is used to connect with the solar panel placed on the upper layer. The connection method is to pass through the first fixing rod 200 through the first through hole 110 to connect all vertically placed solar panels.

[0047] Furthermore, the first through hole 110 can also be used to suspend the solar panel.

[0048] The second through hole 120 is used to connect with the horizontally placed solar panels. The connection method is to pass through the second fixing rod 300 through the second through hole 120 to connect all the horizontally placed solar panels.

[0049] join Figure 8 Furthermore, in some embodiments, the device further includes a container mounting frame 400, which can be understood as a shell fitted onto the solar panel. However, this shell has no side walls and consists only of a frame. The solar panel is fixed in the container mounting frame 400 by the mounting connection assembly 100, the first fixing rod 200, and the second fixing rod 300. When the solar panel needs to be removed, the container mounting frame 400 only needs to be lifted out, and the solar panel can be lifted out in a more spacious area.

[0050] In order to facilitate the transfer and storage of solar panels, the container placement frame 400 in this embodiment is set as an N-shaped structure with three openings. It should be noted that the three openings should be understood as having a frame on three sides but no side walls.

[0051] In order to fix and load the solar panel, the axes of the first through hole 110 and the second through hole 120 need to be set in two non-overlapping planes to avoid the fixing rods from colliding.

[0052] See Figures 2 to 7It can be seen that, further, in some embodiments, the first fixing rod 200 has a plurality of evenly arranged first clamping rods 210, and the second fixing rod 300 has a plurality of evenly arranged second clamping rods 310, wherein the distance between two adjacent first clamping rods 210 is designed to correspond to the vertical dimension of the solar panel, and the distance between two adjacent second clamping rods 310 is designed to correspond to the horizontal dimension of the solar panel.

[0053] When multiple solar panels need to be fixed vertically, the first fixing rod 200 passes through all solar panels through the first through hole 110, and each solar panel is secured by the first clamping rod 210. Similarly, when multiple solar panels need to be fixed horizontally, the second fixing rod 300 passes through all solar panels through the second through hole 120, and each solar panel is secured by the second clamping rod 310.

[0054] The first latch 210 is connected to the solar panel in the following manner:

[0055] A first rotating groove 130 is provided in the first through hole 110. The size of the first rotating groove 130 is adapted to the size of the first clamping rod 210. When vertical fixation is required, the first fixing rod 200 is inserted into the first through hole 110 and rotated when it reaches the preset position to clamp the first clamping rod 210 in the first rotating groove 130, thereby realizing the vertical fixation of the solar panel.

[0056] The second latch 310 is connected to the solar panel in the following manner:

[0057] A second rotating groove 140 is provided in the second through hole 120. The size of the second rotating groove 140 is adapted to the size of the second clamping rod 310. When horizontal fixation is required, the second fixing rod 300 is inserted into the second through hole 120 and rotated when it reaches the preset position to lock the second fixing rod 300 in the second rotating groove 140, thereby realizing the horizontal fixation of the solar panel.

[0058] join Figure 8 Furthermore, in some embodiments, the container placement frame 400 is also provided with four bottom rotating grooves 410 and several side rotating grooves 420.

[0059] The four bottom rotating grooves 410 correspond to the positions of each of the first through holes 110, and a first connecting rod 220 is provided at one end of the first fixing rod 200. The dimensions of the bottom rotating grooves 410 and the first connecting rod 220 are adapted to each other. The bottom rotating grooves 410 and the first rotating grooves 130 have the same structure, and the first connecting rod 220 is locked in the bottom rotating grooves 410, thereby achieving vertical fixation to the container placement frame 400.

[0060] The side rotation grooves 420 correspond to the positions of each of the second through holes 120, and a second connecting rod 320 is provided at one end of the second fixing rod 300. The dimensions of the side rotation grooves 420 are adapted to the first connecting rod 220. The side rotation grooves 420 and the second rotation grooves 140 have the same structure, and the second connecting rods 320 are thus secured in the side rotation grooves 420, thereby achieving lateral fixation to the container mounting frame 400.

[0061] For ease of explanation, the above description has been provided in conjunction with specific embodiments. However, the discussion in some embodiments is not intended to be exhaustive or to limit the embodiments to the specific forms disclosed above. Various modifications and variations can be obtained based on the above teachings. The selection and description of the above embodiments are for the purpose of better explaining the contents of this disclosure, thereby enabling those skilled in the art to better utilize the embodiments.
