Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module frame technology, specifically a water-blocking photovoltaic module frame. Background Technology

[0002] The photovoltaic module frame is an important component of the photovoltaic module. By connecting with the module, the frame provides a robust framework structure for the entire module, enabling it to maintain a stable shape. It not only increases the structural strength of the photovoltaic module but also enables the installation and support of the photovoltaic module.

[0003] In existing photovoltaic module frames, the sealing between the frame and the photovoltaic module is poor. During rainy days, rainwater or moisture can easily seep into the space between the frame and the photovoltaic module and is difficult to drain. This results in the edges of the photovoltaic module being in a humid environment for a long time. After prolonged use, moisture between the frame and the photovoltaic module can easily enter the internal structure of the photovoltaic module, which can affect the normal operation of the photovoltaic module. To address this problem, a water-blocking photovoltaic module frame is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a water-blocking photovoltaic module frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A water-blocking photovoltaic module frame, comprising a base plate, outer side plate, inner side plate, top baffle, and bottom plate; The outer side plate is set on one side of the top of the base plate, the upper baffle is fixed to the top of the outer side plate, the lower plate is located below the upper baffle and one end is connected to the outer side plate, and a plug-in groove for installing photovoltaic modules is formed between the outer side plate, the upper baffle and the lower plate. The inner side plate is located on one side of the outer side plate and fixed to the top of the base plate, and the top of the inner side plate is connected to the lower plate. It also includes water-blocking tape, which is installed inside the insertion slot.

[0006] As a further embodiment of this utility model: the water-blocking tape includes aluminum foil, butyl rubber and release film, which are connected in sequence.

[0007] As a further embodiment of this utility model: the inside of the insertion groove is provided with multiple sets of semi-circular protrusions, the multiple sets of semi-circular protrusions are arranged sequentially, butyl rubber is adhered to one side of the multiple semi-circular protrusions, and aluminum foil is located on the side of the butyl rubber away from the semi-circular protrusions.

[0008] As a further embodiment of this utility model: multiple water guide clips are snapped onto the outer walls of the upper baffle, the outer side plate, and the bottom plate, and the multiple water guide clips are arranged at equal intervals along the length direction of the outer side plate.

[0009] As a further embodiment of this utility model: multiple reinforcing ribs are provided on both sides of the inner side plate, and the multiple reinforcing ribs are equidistantly arranged along the length of the inner side plate. The two ends of each reinforcing rib are respectively connected to the bottom plate and the download plate.

[0010] As a further embodiment of this utility model: multiple reinforcing ribs are provided on the side of the base plate and the download plate that are close to each other, and each reinforcing rib extends along the length direction of the base plate or the download plate.

[0011] As a further embodiment of this utility model: multiple mounting holes are provided on the base plate, and all mounting holes are located on the side of the inner side plate away from the outer side plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The water-blocking photovoltaic module frame of this utility model, by setting aluminum foil and butyl rubber inside the insertion groove, and by adhering the aluminum foil inside the insertion groove, allows the aluminum foil on the butyl rubber side to wrap around the side of the photovoltaic module after the photovoltaic module is installed. The aluminum foil can play a water-blocking role, which can effectively reduce the possibility of water vapor entering between the frame and the photovoltaic module, causing the edge of the photovoltaic module to be in a humid environment for a long time. This can effectively reduce the possibility of water vapor entering the internal structure of the photovoltaic module, which is conducive to extending the life of the photovoltaic module. 2. The water-blocking photovoltaic module frame of this utility model has a continuous semi-circular protrusion on the inner wall of the insertion groove, which makes the inside of the insertion groove form a continuous semi-circular design. The continuous semi-circular design can increase the effective contact area between the butyl rubber and the insertion groove, thereby increasing the contact area between the butyl rubber and the frame body, increasing the bonding area, and using the increased surface area to increase the distance for water vapor to penetrate, thus achieving the water-blocking effect.

[0013] 3. The water-blocking photovoltaic module frame of this utility model can divert water accumulated on the surface of the photovoltaic module by setting multiple water-guiding clips on the outer wall of the frame, so as to avoid the accumulation and retention of rainwater and enable the water to be discharged quickly, thus achieving an effective water guiding effect.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] The present invention provides the following preferred embodiments: Example 1, as Figures 1-6 As shown, the frame of the water-blocking photovoltaic module includes a base plate 11, an outer side plate 12, an inner side plate 13, an upper baffle 14, and a lower plate 15; The outer side plate 12 is located on one side of the top of the base plate 11. The upper baffle 14 is fixed to the top of the outer side plate 12. The lower plate 15 is located below the upper baffle 14 and one end is connected to the outer side plate 12. A plug-in groove 16 for installing photovoltaic modules is formed between the outer side plate 12, the upper baffle 14 and the lower plate 15. The inner side plate 13 is located on one side of the outer side plate 12 and fixed to the top of the base plate 11. The top of the inner side plate 13 is connected to the lower plate 15. The inner side plate 13 can provide support and reduce the possibility of deformation of the lower plate 15, thereby ensuring the stability of the plug-in groove 16 and avoiding the situation where deformation of the plug-in groove 16 causes gaps between the plug-in groove 16 and the photovoltaic modules, reducing the sealing effect. The frame body consists of a base plate 11, an outer side plate 12, an inner side plate 13, an upper baffle plate 14, and a download plate 15. The base plate 11, outer side plate 12, inner side plate 13, upper baffle plate 14, and download plate 15 are all made of aluminum alloy. The photovoltaic module is installed using the insertion slot 16. The outer side plate 12, upper baffle plate 14, and download plate 15 can wrap the sides of the photovoltaic module to increase the structural strength of the photovoltaic module and realize the installation and support of the photovoltaic module. It also includes a water-blocking tape 21, which is installed inside the insertion slot 16. The main function of the water-blocking tape 21 is to prevent moisture penetration and protect the electrical components and cells of the photovoltaic module from damage.

[0023] like Figures 1-6As shown, the water-blocking tape 21 includes aluminum foil 22, butyl rubber 23 and release film 24, which are connected in sequence. Butyl adhesive 23 is coated on aluminum foil 22, and release film 24 is covered on the other side of butyl adhesive 23. Release film 24 is used to protect butyl adhesive 23. When using, release film 24 is peeled off and bonded to the inner wall of insertion groove 16 to effectively prevent moisture. Aluminum foil 22 can wrap the side of photovoltaic module. The aluminum foil 22 can play a water-blocking role, which can effectively reduce the possibility of moisture entering between the frame and photovoltaic module, causing the edge of photovoltaic module to be in a humid environment for a long time. This can effectively reduce the possibility of moisture entering the internal structure of photovoltaic module, which is conducive to extending the life of photovoltaic module.

[0024] like Figures 1-6 As shown, the insertion slot 16 has multiple sets of semi-circular protrusions 25 inside, and the multiple sets of semi-circular protrusions 25 are arranged in sequence. Butyl glue 23 is adhered to one side of the multiple semi-circular protrusions 25, and aluminum foil 22 is located on the side of butyl glue 23 away from the semi-circular protrusions 25. Specifically, the multiple semi-circular protrusions 25 are respectively fixed on the surface of the outer side plate 12, the upper baffle 14 and the download plate 15. By providing continuous semi-circular protrusions 25 on the inner wall of the insertion groove 16, a continuous semi-circular design is formed inside the insertion groove 16. The continuous semi-circular design can increase the effective contact area between the butyl rubber 23 and the insertion groove 16, thereby increasing the contact area between the butyl rubber 23 and the frame body, increasing the bonding area, and using the increased surface area to increase the distance for water vapor to penetrate, thus achieving the effect of water resistance.

[0025] like Figures 1-6 As shown, multiple water guide clips 20 are snapped onto the outer walls of the upper baffle 14, the outer side plate 12 and the bottom plate 11, and the multiple water guide clips 20 are arranged at equal intervals along the length direction of the outer side plate 12. The core principle of the water guide clip 20 is the siphon effect. The water guide clip 20 forms a height difference through a pre-installed pipe, which generates a pressure difference on the surface of the photovoltaic panel, triggering the siphon phenomenon and causing water to be discharged quickly along the preset path. The water guide clip 20 is existing technology and will not be described in detail here. By setting multiple water-guiding clips 20, the water accumulated on the surface of the photovoltaic module can be diverted, preventing rainwater from accumulating and stagnating, so that the water can be drained quickly, achieving an effective water guiding effect.

[0026] like Figures 1-6 As shown, multiple reinforcing ribs 18 are provided on both sides of the inner side plate 13. The multiple reinforcing ribs 18 are equidistantly arranged along the length of the inner side plate 13. The two ends of each reinforcing rib 18 are connected to the bottom plate 11 and the download plate 15 respectively. The reinforcing ribs 18 can further increase the strength of the inner side plate 13, play an effective supporting and strengthening role, and ensure the stability of the frame in the vertical direction.

[0027] like Figures 1-6 As shown, multiple reinforcing ribs 17 are provided on the side of the base plate 11 and the download plate 15 that are close to each other, and each reinforcing rib 17 extends along the length direction of the base plate 11 or the download plate 15. The multiple reinforcing ribs 17 provide a good anti-deformation effect, ensuring the stability of the frame in the length direction.

[0028] like Figures 1-6 As shown, the base plate 11 has multiple mounting holes 19, all of which are located on the side of the inner side plate 13 away from the outer side plate 12. The mounting holes 19 facilitate the installation of the frame on the bracket. Specifically, during installation, bolts that mate with the mounting holes 19 are used to install the frame and the bracket.

[0029] The beneficial effects of this utility model are specifically reflected in the fact that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. 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.
