Description

Technical Field

[0001] This utility model relates to the field of solar aluminum frame technology, specifically to a solar aluminum frame with a waterproof sealing structure. Background Technology

[0002] In solar photovoltaic systems, aluminum frames serve as the core support and protection components for rigid photovoltaic panels. They must simultaneously fulfill three major functions: structural fixation, edge sealing, and installation compatibility. The rationality of their design directly affects the service life and operational stability of the photovoltaic panels. Currently, mainstream solar aluminum frames generally adopt a "fully enclosed closed frame" structure. By filling the grooves of the frame with sealing strips, a continuous sealing barrier is formed around the edge of the photovoltaic panel to prevent external impurities such as rainwater and dust from seeping into the interior through the gaps between the frame and the glass and back panel, thus avoiding faults such as short circuits of the solar cells and circuit corrosion.

[0003] The existing aluminum frame sealing strip, after filling, easily forms a raised structure together with the outer edge of the aluminum frame. The combined height of the sealing strip and the aluminum frame will exceed the glass surface plane of the photovoltaic panel. When rainwater flows down the inclined surface of the photovoltaic panel, it will be blocked by the raised strip and the frame when it reaches the frame area, and cannot continue to flow smoothly down the slope of the panel. As a result, local water accumulation will form at the junction of the raised structure and the glass surface. The stagnant rainwater will be in contact with the sealing strip and the glass edge for a long time, accelerating the aging and cracking of the sealing strip. Utility Model Content

[0004] To address this issue, this utility model provides a solar aluminum frame with a waterproof sealing structure. By using adhesive strips to firmly attach the components, it solves the problem of raised structures in traditional seals causing localized water accumulation at the junction with the photovoltaic panel surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solar aluminum frame with a waterproof and sealed structure, comprising an aluminum frame body, a lower edge aluminum frame fixedly provided on one side of the aluminum frame body, a glue strip groove fixedly provided inside the aluminum frame body, a sealing glue strip body fixedly provided inside the glue strip groove, a photovoltaic panel fixedly provided inside the sealing glue strip body, a lower edge sealing glue strip provided on one side of the photovoltaic panel, a glue strip fastening assembly provided outside the lower edge sealing glue strip, the glue strip fastening assembly including a fixing frame, a threaded rod provided on one side of the fixing frame, two knobs fixedly sleeved on the outside of the threaded rod, a plurality of threaded blocks sleeved on the outside of the threaded rod, a pull plate seat fixedly provided at one end of each of the plurality of threaded blocks, a sliding rod fixedly provided inside each of the plurality of pull plate seats, a pull plate sleeved on the outside of each of the plurality of sliding rods, an inclined groove provided inside each of the plurality of pull plates, and a clamping plate fixedly provided at one end of each of the plurality of pull plates.

[0006] Preferably, the two ends of the fixing frame are fixedly connected to the two side walls of the aluminum frame body, respectively.

[0007] Preferably, the two ends of the threaded rod pass through the two side walls of the aluminum frame body and are connected to the two side walls of the aluminum frame body through bearings.

[0008] Preferably, the threaded block is sleeved on the outside of the threaded rod and connected to the threaded rod by threads, and one side of the threaded block contacts one side wall of the fixing frame and is slidably connected to one side wall of the fixing frame.

[0009] Preferably, the slide bar passes through the inclined groove and is slidably connected to the inclined groove.

[0010] Preferably, the clamping plate is disposed inside the aluminum frame body and is slidably connected to the aluminum frame body.

[0011] Preferably, both ends of the extrusion plate extend into the groove of the adhesive strip and are slidably connected to the groove of the adhesive strip.

[0012] Preferably, the top of the extrusion plate is fixedly connected to the lower edge sealing strip, and the lower edge sealing strip is in contact with one side wall of the photovoltaic panel.

[0013] The present invention has the following advantages: The photovoltaic panel is sealed on three sides by the sealing strip body. The lower edge sealing strip is adjusted to fit the strip tightly against the module. This ensures that the lower edge sealing strip fits tightly against the lower edge of the photovoltaic panel, while also ensuring that its top is flush with the glass surface of the photovoltaic panel and does not form a water-blocking edge. At the same time, the drainage gap between the lower edge sealing strip and the lower edge aluminum frame is maintained, so that rainwater can be smoothly discharged along the inclined panel surface through the gap, completely solving the water accumulation problem caused by the protrusion of the traditional aluminum frame sealing strip. The cooperation of the fixed frame, threaded rod and threaded block ensures the directional transmission of the threaded block. The linkage of the sliding rod, inclined groove and extrusion plate achieves precise adhesion of the lower edge sealing strip. It can be manually adjusted by the knob, which is simple to operate. The sliding cooperation between the extrusion plate and the aluminum frame body and the strip groove further improves the structural stability and adapts to the sealing requirements of photovoltaic panels of different thicknesses.

Detailed Implementation

[0018] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0019] See attached document Figure 1 -Appendix Figure 4This utility model provides a solar aluminum frame with a waterproof and sealed structure, including an aluminum frame body 1, a lower edge aluminum frame 2 fixedly provided on one side of the aluminum frame body 1, a glue strip groove 3 fixedly provided inside the aluminum frame body 1, a sealing glue strip body 4 fixedly provided inside the glue strip groove 3, a photovoltaic panel 5 fixedly provided inside the sealing glue strip body 4, a lower edge sealing glue strip 6 provided on one side of the photovoltaic panel 5, and a glue strip fastening component 7 provided outside the lower edge sealing glue strip 6. The glue strip fastening component 7 includes a fixing frame 71, a threaded rod 72 provided on one side of the fixing frame 71, two knobs 73 fixedly sleeved outside the threaded rod 72, a plurality of threaded blocks 74 sleeved outside the threaded rod 72, a pull plate seat 75 fixedly provided at one end of each of the plurality of threaded blocks 74, a sliding rod 76 fixedly provided inside each of the plurality of pull plate seats 75, a pull plate 77 sleeved outside each of the plurality of sliding rods 76, a slanted groove 78 provided inside each of the plurality of pull plates 77, and a squeezing plate 79 fixedly provided at one end of each of the plurality of pull plates 77. In this implementation scheme, to achieve both waterproof sealing and prevention of water accumulation, the photovoltaic panel 5 is fixed, and its left, right, and upper edges are embedded inside the sealing strip body 4 in the adhesive strip groove 3 of the aluminum frame body 1. The sealing strip body 4 elastically wraps around the edges to prevent water seepage on three sides. The lower edge of the photovoltaic panel 5 is sealed, and the lower edge sealing strip 6 cooperates with the adhesive strip fastening assembly 7 to seal the lower edge of the photovoltaic panel 5. The knob 73 on the outside of the threaded rod 72 is held and turned clockwise (adjusted as needed). The threaded rod 72 drives the threaded block 74 to move axially. The threaded block 74 drives the pull plate seat 75 and the slide rod 76 to move. The slide rod 76 passes through the inclined groove 78 of the pull plate 77. When the threaded block 74 moves forward towards the aluminum frame body 1, the pull plate 77 drives the clamping plate 79 to move towards the photovoltaic panel 5 through the cooperation of the pull plate 77 and the inclined groove 78. The clamping plate 79 pushes the sealing strip 6 towards the lower edge of the photovoltaic panel 5. After it is tightly attached, the lower edge sealing strip 6 is both sealed and does not block water. The distance between it and the lower edge aluminum frame 2 leaves a drainage channel, so as to achieve both waterproof sealing and prevention of water accumulation. To achieve the goal of allowing the threaded block 74 to move only along the axial direction of the threaded rod 72, the device employs the following technical solution: the two ends of the fixed frame 71 are fixedly connected to the two side walls of the aluminum frame body 1, the two ends of the threaded rod 72 pass through the two side walls of the aluminum frame body 1 and are connected to the two side walls of the aluminum frame body 1 through bearings, the threaded block 74 is sleeved on the outside of the threaded rod 72 and is connected to the threaded rod 72 through threads, one side of the threaded block 74 contacts one side wall of the fixed frame 71 and is slidably connected to one side wall of the fixed frame 71, when the knob 73 is rotated to drive the threaded rod 72 to rotate, the threaded block 74 is limited by the side wall of the fixed frame 71 and cannot rotate synchronously with the threaded rod 72, but can only move linearly along the threaded trajectory of the threaded rod 72, thus accurately realizing directional transmission and providing stable power for subsequently driving the slide rod 76 and squeezing the lower edge sealing strip 6; To achieve the goal of the lower edge sealing strip 6 being tightly attached to the lower edge of the photovoltaic panel 5, the device employs the following technical solution: A sliding rod 76 passes through and is slidably connected to the inclined groove 78; a clamping plate 79 is located inside the aluminum frame body 1 and is slidably connected to it; both ends of the clamping plate 79 extend into the sealing strip groove 3 and are slidably connected to it; the top of the clamping plate 79 is fixedly connected to the lower edge sealing strip 6; and the lower edge sealing strip 6 contacts one side wall of the photovoltaic panel 5. When the threaded block 74 drives the pull plate seat 75 and the sliding rod 76 to move forward, the sliding rod 76, because it passes through and slides in the inclined groove 78 of the pull plate 77, and the inclined groove 78 is inclined, will have its displacement converted along the trajectory of the inclined groove 78. Pull plate 77 is pulled horizontally to the left; at this time, the clamping plate 79 is located inside the aluminum frame body 1 and is slidably connected to the aluminum frame body 1. At the same time, both ends extend into the adhesive strip groove 3 and slide in cooperation with the adhesive strip groove 3. The double sliding limit ensures that it can only move in the vertical direction; since the top of the clamping plate 79 is fixedly connected to the lower edge sealing strip 6, the clamping plate 79 will drive the lower edge sealing strip 6 to move simultaneously until the lower edge sealing strip 6 is in close contact with the side wall of the photovoltaic panel 5 and the top is flush with the glass surface of the photovoltaic panel 5 (without forming a water-blocking edge); the whole process not only achieves precise sealing of the photovoltaic panel 5 by the lower edge sealing strip 6, but also avoids the strip from bulging, while maintaining the drainage gap between the lower edge sealing strip 6 and the lower edge aluminum frame 2, thus taking into account both sealing and drainage functions.

[0020] The usage process of this utility model is as follows: When using this utility model, first fix the photovoltaic panel 5 and complete the three-sided sealing. Embed its left, right, and upper edges into the sealing strip body 4 of the inner rubber strip groove 3 of the aluminum frame body 1. The sealing strip body 4 wraps the edge of the photovoltaic panel 5 through elastic deformation. Next, handle the sealing and drainage of the lower edge of the photovoltaic panel 5. The lower edge sealing strip 6 cooperates with the rubber strip fastening component 7 to seal the lower edge of the photovoltaic panel 5. First, connect the lower edge sealing strip 6 to the top of the extrusion plate 79. When tightening is required, adjust the rubber strip fastening component 7. Hold the knob 73 outside the threaded rod 72 and turn it clockwise (adjust as needed). The threaded rod 72 drives the threaded block 74 to move axially. The threaded block 74 drives the pull plate seat 75 and the slide rod 76 to move. The slide rod 76 passes through the inclined groove 78 of the pull plate 77. When 74 moves forward, through the cooperation of the pull plate 77 and the inclined groove 78, the pull plate 79... 7. The clamping plate 79 is moved towards the photovoltaic panel 5. The clamping plate 79 pushes the sealing strip 6 towards the lower edge of the photovoltaic panel 5. After it is tightly attached, the lower edge sealing strip 6 is both sealed and does not block water. The gap between the lower edge sealing strip 6 and the lower edge aluminum frame 2 leaves a drainage channel. Finally, the aluminum frame body 1 is installed at an angle (lower edge facing the drainage direction). When it rains, rainwater flows along the inclined surface of the photovoltaic panel 5. Because the sealing strip body 4 is flush and unobstructed, the rainwater on the three sides flows to the area of ​​the lower edge aluminum frame 2 and is discharged through the gap between the lower edge sealing strip 6 and the lower edge aluminum frame 2 without stagnation. The sealing strip body 4 and the lower edge sealing strip 6 seal to prevent rainwater from seeping into the aluminum frame body 1, protecting the photovoltaic panel 5 cells and circuits. This design solves the problem of water accumulation caused by the protrusion of the traditional sealing strip. The sealing strip is tightly attached to the component 7 and precisely adjusted to ensure a seal. It reduces the immersion of the sealing strip body 4 and the lower edge sealing strip 6 in rainwater, freeze-thaw aging, extends the life and improves waterproof reliability.

Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
