Description

Technical Field

[0001] This utility model belongs to the field of solar panel installation technology, and in particular relates to a solar panel connection structure. Background Technology

[0002] When solar panels are installed over a large area, each panel is typically fixed individually. This method requires a large number of components, with each support plate corresponding to a pressure plate. In other words, a support plate and a pressure plate work together to fix the solar panel at a single point along its edge. The solar panel is only fixed at the point where the pressure plate and support plate are located, which can potentially affect the stability of the solar panel installation. Furthermore, when installing the support plates, they are strung across the support frame and then riveted together, making the operation cumbersome and affecting installation efficiency. Utility Model Content

[0003] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a solar panel connection structure.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A solar panel connection structure includes multiple waterproof frames arranged side by side and spaced apart. Multiple support plates with upward protruding waterproof grooves and spaced apart are snapped into the waterproof grooves of each waterproof frame. A pressure plate is fixedly connected between the upper sides of the multiple support plates in each waterproof frame. A solar panel is installed between two adjacent waterproof frames, and the left and right sides of the solar panel are snapped between the corresponding pressure plate and support plate.

[0006] Furthermore, the waterproof frame includes inverted V-shaped protrusions on the left and right sides and a connecting part located between the inner bottom ends of the two protrusions. Each protrusion has a horizontally outward mounting part at its outer bottom end. The inner sides of the two protrusions and the connecting part form a waterproof groove. The connection between the protrusions and the connecting part is horizontally recessed outward along the bottom of both sides of the waterproof groove to form a snap-fit ​​groove communicating with the waterproof groove. The support plate includes a support part, a load-bearing part, a support part, and a snap-fit ​​part. The load-bearing part has an L-shaped structure and is symmetrically arranged on both sides of the support part. The two support parts are inclined outward and symmetrically arranged at the outer ends of the corresponding horizontal sections of the load-bearing part. A snap-fit ​​part is horizontally outward at the lower end of each support part, and the snap-fit ​​part snaps into the snap-fit ​​groove.

[0007] Furthermore, the pressure plate includes a U-shaped connecting section and a pressing section horizontally outwardly arranged at the top of both sides of the connecting section. The bottom of the connecting section abuts against the upper side of the support part of the corresponding multiple support plates, and each support part is fixed together with the connecting section by bolts and nuts. The lower side of the frame of the solar panel overlaps the upper side of the horizontal section of the bearing part, and the upper side abuts against the bottom of the pressing section.

[0008] Furthermore, a first through hole is provided in the middle of the support part, and a second through hole is provided on the connecting section corresponding to each first through hole. The bolt passes through the first through hole and the second through hole, and a washer and a spring washer are sequentially fitted from bottom to top at the connecting groove of the connecting section on the upper part of the bolt. The nut is screwed onto the bolt and abuts against the upper side of the spring washer.

[0009] Furthermore, at the bottom center of each solar panel, there is an auxiliary support frame arranged parallel to the waterproof frame. The auxiliary support frame includes a support section and an overlapping section. The support section is horizontally arranged, and the overlapping section has a 7-shaped structure. Its bottom end is fixed to one end of the support section, and it is inclined above the support section towards the other end of the support section. The top of the overlapping section abuts against the bottom of the corresponding solar panel.

[0010] Furthermore, the number of solar panels between two adjacent waterproof frames is one.

[0011] Furthermore, there are multiple solar panels between two adjacent waterproof frames, which are distributed longitudinally, and a water guide plate is provided at the bottom of the joint between two longitudinally adjacent solar panels, which overlaps the upper side of the two waterproof frames.

[0012] Furthermore, the water guide plate is a U-shaped plate, and there are horizontal outward abutting edges on the top of both sides of the U-shaped plate, with the two abutting edges abutting against the bottom of two longitudinally adjacent solar panels.

[0013] Furthermore, multiple mounting holes are evenly provided on the mounting section of the waterproof frame. The waterproof frame is fixed to the upper side of the crossbeam by U-bolts that fit into the mounting holes, and the auxiliary support frame overlaps the upper side of the crossbeam.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] As shown in the figure, a solar panel connection structure includes multiple waterproof frames 1 arranged side-by-side and spaced apart. Multiple upward-protruding, spaced-apart support plates 2 are snapped into the waterproof grooves of each waterproof frame 1. A pressure plate 3 is fixedly connected to the upper sides of the support plates 2 in each waterproof frame 1. A solar panel 7 is installed between two adjacent waterproof frames 1, with both sides of the solar panel 7 snapped between the corresponding pressure plate 3 and support plate 2. In this embodiment, by snapping the support plates 2 into the waterproof grooves of the waterproof frame 1 and fixing the pressure plate 3 to the upper sides of the multiple longitudinally distributed support plates 2, multiple longitudinally distributed solar panels 7 can be fixed by a single pressure plate 3, effectively reducing the number of parts required for installing the solar panels 7 and making installation convenient and quick.

[0029] The waterproof frame 1 includes an inverted V-shaped protrusion 101 protruding upwards on both the left and right sides and a connecting part 102 located between the inner bottom ends of the two protrusions 101. Each protrusion 101 has a horizontally outward mounting part 104 at its outer bottom end. A waterproof groove is formed between the inner sides of the two protrusions 101 and the connecting part 102. The connection between the protrusions 101 and the connecting part 102 is horizontally recessed outwards along the bottom of both sides of the waterproof groove to form a snap-fit ​​groove 103 communicating with the waterproof groove. The support plate 2 includes a support part 201, a bearing part 202, a support part 203, and a snap-fit ​​part 204. The bearing part 202 has an L-shaped structure and is symmetrically arranged on both sides of the support part 201. The two support parts 203 are inclined outwards and symmetrically arranged at the outer ends of the horizontal sections of the corresponding bearing parts 202. A snap-fit ​​part 204 is horizontally outwards at the lower end of each support part 203. The snap-fit ​​part 204 snaps into the snap-fit ​​groove 103. In this embodiment, one side of the protrusion 101 is a vertical section and the other side is an inclined section, or both sides are symmetrical inclined sections.

[0030] The pressure plate 3 includes a U-shaped connecting section 301 and a pressing section 302 horizontally outwardly arranged at the top of both sides of the connecting section 301. The bottom of the connecting section 301 abuts against the upper side of the support portion 201 of the corresponding multiple support plates 2, and each support portion 201 is fixed together with the connecting section 301 by the cooperation of bolts 9 and nuts 4. The lower side of the frame of the solar panel 7 overlaps the upper side of the horizontal section of the bearing portion 202, and the upper side abuts against the bottom of the pressing section 302.

[0031] A first through hole is provided in the middle of the support portion 201. A second through hole is provided on the connecting section 301 corresponding to each first through hole. The bolt 9 passes through the first and second through holes. A washer 10 and a spring washer 11 are sequentially fitted from bottom to top on the upper part of the bolt 9 at the connecting groove of the connecting section 301. The nut 4 is screwed onto the bolt 9 and abuts against the upper side of the spring washer 11. In this embodiment, the washer 10 and the spring washer 11 are provided to prevent the nut 4 from loosening and to raise the nut 4, ensuring that the nut 4 is located above the crimping section 302. This makes it easier to tighten the nut 4 with a wrench when installing it.

[0032] At the bottom center of each solar panel 7, an auxiliary support frame 5 is abutted against, arranged parallel to the waterproof frame 1. The auxiliary support frame 5 includes a support section 501 and an overlapping section 502. The support section 501 is horizontally positioned, and the overlapping section 502 has a "7"-shaped structure, with its bottom end fixed to one end of the support section 501 and inclined towards the other end of the support section 501 above it. The top end of the overlapping section 502 abuts against the bottom of the corresponding solar panel 7. In this embodiment, the auxiliary support frame 5 is entirely located inside the frame of the corresponding solar panel 7.

[0033] The number of solar panels 7 between two adjacent waterproof frames 1 is one.

[0034] There are multiple solar panels 7 between two adjacent waterproof frames 1, which are distributed longitudinally. At the bottom of the joint between two longitudinally adjacent solar panels 7, there is a water guide plate 6 that overlaps the upper side of the two waterproof frames 1. This is used to guide the water falling from the gap between the two longitudinally adjacent solar panels 7 into the waterproof frame 1 and then out of the waterproof frame 1.

[0035] The water guide plate 6 is a U-shaped plate, and has horizontal outward abutment edges on both sides of the top edge of the U-shaped plate. The two abutment edges abut against the bottom of two longitudinally adjacent solar panels 7. In this embodiment, the abutment edges are located inside the frame of the solar panel 7.

[0036] Multiple mounting holes are evenly distributed on the mounting section 104 of the waterproof frame 1. The waterproof frame 1 is fixed to the upper side of the crossbeam 8 by U-bolts 12 engaging with the mounting holes. The auxiliary support frame 5 overlaps the upper side of the crossbeam 8. In this embodiment, each solar panel 7 corresponds to at least two crossbeams 8 to ensure the installation stability of the auxiliary support frame 5. The crossbeams 8 are installed on the roof or on a bracket.

[0037] In this embodiment, the waterproof frame 1, the support plate 2, the pressure plate 3, the water guide plate 6, and the auxiliary support frame 5 are all integrally formed structures.

[0038] Pallet 2 is made of aluminum-magnesium-zinc coated material.

[0039] The working process of this embodiment is as follows:

[0040] During installation, the waterproof frame 1 is fixed in place. A pressure plate 3 and multiple support plates 2 are initially assembled together using bolts 9, washers 10, spring washers 11, and nuts 4. At this stage, the nuts 4 do not need to be tightened; simply ensure the pressure plate 3 and support plates 2 are connected. This process is repeated to initially assemble multiple sets of pressure plate and support plate assemblies. Then, the pre-assembled pressure plate and support plate assemblies are pressed into the corresponding waterproof frame 1. During pressing, the clamping part 204 of the support plate 2 experiences greater force as it is pressed down, causing the support parts 203 on both sides of the support plate 2 to be subjected to… The force causes a slight inward deformation until the snap-fit ​​part 204 snaps into the snap-fit ​​groove 103, at which point the support part 203 springs back outward. Before installing the solar panel 7, install the auxiliary support frame 5 and the water guide plate 6 in place, and then install the solar panel 7. During installation, since the pressure plate and support plate assembly is initially loose, the pressure plate 3 can be lifted to a certain height, and the edge of the solar panel 7 can be inserted between the pressure plate 3 and the support plate 2. After laying a row of solar panels in place, start tightening the nuts 4 one by one to press the edge of the solar panel 7 tightly with the pressure plate 3. Of course, since the allowance between the pressure plate 3 and the support plate 2 has been reserved in advance, the solar panel 7 can also be inserted between the pressure plate 3 and the support plate 2 from one end of the waterproof frame 1. After laying a row of longitudinally distributed solar panels 7 in place, tighten the nuts 4 on both sides of the pressure plate 3.

[0041] After the solar panel 7 is installed, the support parts 203 on both sides of the tray 2 will continue to be squeezed outward to a certain extent under the pressure of the solar panel 7, so that the snap-fit ​​part 204 is pressed against the snap-fit ​​groove 103, ensuring the installation stability of the tray 2 in the waterproof frame 1.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
