Description

Technical Field

[0001] The utility model relates to a high-load photovoltaic component and belongs to the field of photovoltaic component structures. Background Art

[0002] A photovoltaic module generally consists of a photovoltaic module body for receiving solar energy and generating electricity and a frame. For a single-glass photovoltaic module, the photovoltaic module body is composed of glass, battery cells, a back panel, etc. For a double-glass photovoltaic module, the photovoltaic module body is composed of two pieces of glass, battery cells, etc. The photovoltaic module body is installed in the frame groove of the frame and sealed with a sealant, such as a photovoltaic module announced in announcement number CN208001253U.

[0003] When assembling a photovoltaic module, first fill the frame notch with liquid glue, then install the main body of the photovoltaic module into the frame notch. During the framing process, the glue is squeezed and flows, and fills the upper glue-filling channel formed by the upper surface of the photovoltaic module and the upper groove wall of the frame notch, and the lower glue-filling channel formed by the lower surface of the photovoltaic module and the lower groove wall of the frame notch. After the glue solidifies, the main body of the photovoltaic module is connected to the frame. At the same time, the solidified glue has a certain degree of earthquake and impact resistance. Generally speaking, after framing, the glue thickness in the two glue-filling channels must be consistent, so that both the upper and lower sides of the main body of the photovoltaic module have good earthquake and impact resistance.

[0004] In the prior art, high-load photovoltaic modules (the photovoltaic module body is relatively large in size and heavy) are often installed into the frame slot by hoisting the photovoltaic module body with steel wire ropes. When the photovoltaic module body is inserted into the frame slot, it is difficult to grasp the height of the photovoltaic module body in the frame slot, that is, the width of the upper glue filling channel and the lower glue filling channel is difficult to control, which often leads to the problem that the glue filling channel on one side of the photovoltaic module body is enlarged and the glue filling channel on the other side is reduced. When the glue filling channel is reduced, the amount of glue filling is also reduced, resulting in a reduction in local earthquake and impact resistance. For high-load photovoltaic modules, it is more likely to cause the photovoltaic module body to burst or crack during installation and transportation. Utility Model Content

[0018] Figure 1 This is a simplified schematic diagram of the structure of a high-load photovoltaic module.

[0019] Figure 2 This is a diagram showing the state of the photovoltaic module body being installed into the frame notch;

[0020] Figure 3 This is the matching diagram of the connecting plate and the guide plate. DETAILED DESCRIPTION

[0021] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0022] Example: Figure 1-3 A high-load photovoltaic module is provided, comprising an aluminum alloy frame 1 with a frame notch 11, a photovoltaic module body 2, a supporting plate 3 located outside the entrance of the frame notch 11, and a lifting assembly 4 connected to the supporting plate 3, wherein the lifting assembly 4 is connected to the aluminum alloy frame 1.

[0023] Before the photovoltaic module body 2 is loaded into the frame slot 11, the supporting plate 3 is located below the frame slot 11; when framing, the photovoltaic module body 2 is first properly inserted into the frame slot 11 without squeezing the glue inside, and then the lifting assembly 4 is used to adjust the height position of the supporting plate 3, the supporting plate 3 holds the photovoltaic module body 2 and changes the height position of the photovoltaic module body 2 until the height position of the photovoltaic module body 2 in the frame slot 11 is at the center of the frame slot 11, and then the photovoltaic module body 2 continues to be loaded into the frame slot 11 until the photovoltaic module body 2 squeezes the glue and fills the two glue filling channels formed by the photovoltaic module body 2 and the frame slot 11.

[0024] The supporting plate 3 always supports the photovoltaic module body 2 and ensures that the height position of the module body 2 in the frame slot 11 is at the center of the frame slot 11 during the process of the photovoltaic module body 2 being loaded into the frame slot 11, ensuring that after the photovoltaic module body 2 is fully loaded, the widths of the two glue filling channels formed on the upper and lower sides of the photovoltaic module body 2 are equal, thereby ensuring that the thickness of the glue filled in the two glue filling channels is equal, ensuring that the two glue layers after solidification have good earthquake and impact resistance, and reducing the situation of photovoltaic module body bursting or hidden cracking during installation, transportation, etc. of high-load photovoltaic modules. In addition, when the photovoltaic module body 2 is loaded into the frame slot 11 while being supported by the supporting plate 3, the probability of collision with the slot wall of the frame slot 11 is smaller, which can also reduce the situation of bursting or hidden cracking of the photovoltaic module body 2 during the framing process to a certain extent.

[0025] In the embodiment, the lifting assembly 4 specifically comprises a screw seat 41 connected to the aluminum alloy frame 1, a screw rod 42 arranged on the screw seat 41, a moving block 43 spirally connected to the screw rod 42 is provided on the screw rod 42, the moving block 43 is connected to the support plate 3 through a connecting plate 44, and a guide plate 45 engaged with the connecting plate 44 is also provided on the aluminum alloy frame 1. This lifting assembly adjusts the height position of the support plate 3 by rotating the screw rod 42. With this lifting assembly, self-locking can be achieved after lifting, which simplifies the operation of the lifting assembly. The number of screw rods 42 is one, which makes the operation of the lifting assembly 4 convenient.

[0026] There are two guide plates 45, which are symmetrically located on both sides of the connecting plate 44. The guide plates 45 are provided with a slot that is engaged with the connecting plate 44. The connecting plate 44 has a clamping head that cooperates with the slot. Through the mutual cooperation between the clamping head and the slot, the slot can provide a fulcrum for the connecting plate 44 nearby, thereby reducing the bending deformation of the connecting plate 44. Otherwise, the connecting plate 44 will bend and deform with the point where the connecting plate 44 is connected to the moving block 43 as the fulcrum, and the bending deformation of the connecting plate 44 will be large.

[0027] The supporting plate 3 includes a connecting portion 31 connected to the connecting plate 44 and a supporting portion 32 connected to the connecting portion 31 .

[0028] The connecting portion 31 is formed with a downwardly recessed recovery groove 33 . During the framing process, the glue is squeezed and flows. If glue overflows from the glue filling channel, the overflowed glue flows into the recovery groove 33 and can be reused.

[0029] The upper surface of the supporting portion 32 is provided with a smooth layer 34 , and the friction resistance between the smooth layer 34 and the photovoltaic module body 2 is small, which makes it more convenient to install the photovoltaic module body 2 into the frame groove 11 , and will not have a significant adverse effect on the glass of the photovoltaic module body 2 .

[0030] In the process of determining the height position of the support plate 3 and continuing to install the photovoltaic module body 2 into the frame groove 11, some unreasonable human actions may cause the side end of the photovoltaic module body 2 to tilt or press down, thereby causing a collision with the groove wall of the frame groove 11, causing explosion or hidden cracks.

[0031] To this end, an anti-collision component 5 is connected to the upper part of the aluminum alloy frame 1, and the anti-collision component 5 includes an anti-collision column 51 and an adjustment component 52 connected to the anti-collision column 51. The adjustment component 52 specifically includes a screw rod frame 521, a lifting screw rod 522 and a screw rod guide rod 523 installed on the screw rod frame 521, and a screw rod slider 524 spirally connected to the lifting screw rod 522 and passed by the screw rod guide rod 523, and the anti-collision column 51 is connected to the screw rod slider 524.

[0032] When the height position of the supporting part 32 is determined and before the photovoltaic module body 2 is further inserted into the frame slot 11, the height position of the anti-collision column 51 is first adjusted by adjusting the component 52, and the lower end of the anti-collision column 51 is moved down to below the upper groove wall of the frame slot 11. At this time, the anti-collision column 51 and the supporting part 32 form a limiting groove 6 for limiting the photovoltaic module body 2, preventing the photovoltaic module body 2 from tilting too much during the framing process and colliding with the groove wall of the metal frame slot 11.

[0033] The above embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the concept and scope of the utility model. Without departing from the design concept of the utility model, various modifications and improvements made by ordinary persons in the art to the technical solution of the utility model should fall within the protection scope of the utility model, and the technical contents of the utility model for protection have been fully recorded in the claims.
