Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaic component installation, and specifically relates to a snap-fit ​​photovoltaic component fixing structure and a photovoltaic system. [Background technology]

[0002] Existing photovoltaic modules are usually installed with a press block, and a 20mm gap is required between two adjacent photovoltaic modules. If a waterproof solution is used, the gap is large and sealed with a rubber strip, which will still cause dripping and fail to meet the seamless waterproof requirements of the module. For the seamless installation method in the prior art, the frames of two adjacent photovoltaic modules are fitted together without leaving any gaps to achieve a waterproof effect, and then a waterproof press block is used to fix the module frame. However, the waterproof press blocks currently on the market are basically fastened with bolts, and the bolts need to be tightened from the bottom of the module, which makes the installation complicated. Therefore, if the seamless installation of photovoltaic modules can be achieved without the need for bolt fasteners, the leakage problem can be reduced and the installation operation can be facilitated. [Contents of the utility model]

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a snap-fit ​​photovoltaic component fixing structure and a photovoltaic system to solve the seamless installation requirements of photovoltaic components, reduce water leakage problems, and facilitate installation operations.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] First, a snap-fit ​​photovoltaic module fixing structure is provided, comprising a crossbeam, a photovoltaic module and a waterproof pressure block, wherein the photovoltaic module has a frame, the frame is installed above the crossbeam, the waterproof pressure block comprises a bottom buckle located at the bottom and a lateral slot arranged above the bottom buckle, a snap-fit ​​portion is provided on the crossbeam, the bottom buckle is snap-fitted with the snap-fit ​​portion, and the frame is snap-fitted in the lateral slot.

[0006] Preferably, the bottom of the frame is provided with a C edge, the top is provided with an A edge, and the lateral slot is provided with an upper engaging edge engaged with the A edge and a lower engaging edge engaged with the C edge.

[0007] Preferably, an upper hook is provided on the edge of the upper locking edge, and a lower hook is provided on the edge of the lower locking edge, and the upper hook cooperates with the edge of the A side, and the lower hook cooperates with the edge of the C side.

[0008] Preferably, the upper hook and the lower hook are curled edges that are bent inwards.

[0009] Preferably, the waterproof pressure block is provided with lateral grooves on two opposite sides thereof, and an intermediate wall embedded between two adjacent photovoltaic component frames is provided between the two lateral grooves.

[0010] Preferably, the engaging portion is a locking hole, and the bottom buckle passes through the locking hole.

[0011] Preferably, the bottom buckle is an inverted umbrella-shaped structure.

[0012] Preferably, the crossbeam is a U-shaped or C-shaped structure, and the clamping hole is arranged on the bottom wall of the crossbeam.

[0013] Preferably, the waterproof pressing block is a profile with an integrated structure.

[0014] The utility model also provides a photovoltaic system, which is provided with the above-mentioned snap-fit ​​photovoltaic component fixing structure.

[0015] The utility model adopts the above technical solution and has the following beneficial effects:

[0016] 1. First, the waterproof pressure block is engaged with the engaging part on the beam through the bottom buckle, so that the waterproof pressure block can be fixed on the beam, and then the photovoltaic module is installed. First, the frame of the photovoltaic module on one side of the waterproof pressure block is pushed and engaged in the lateral groove on the side for fixing, and then the frame of the photovoltaic module on the other side of the waterproof pressure block is pushed and engaged in the lateral groove on the other side for fixing. The whole installation process does not require the use of fasteners such as bolts. Compared with the existing waterproof pressure block fastened with bolts, it is simple and easy to operate, and the installation efficiency is improved; since no bolts are required and the amount of pressure blocks used is small, the cost can be reduced.

[0017] Secondly, the waterproof pressure block is embedded between two adjacent photovoltaic modules, and the lateral slot covers the frame of the photovoltaic module, leaving no gaps to play a waterproof role. There is no need to set up waterproof blocking strips, thus solving the seamless installation requirements of photovoltaic systems on flat roofs, especially sloping roofs, and reducing leakage problems.

[0018] 2. The lower locking edge C of the lateral card slot is locked with the upper locking edge and the A side, so that the frame is locked and fixed from the upper and lower directions, and the edge of the upper locking edge is provided with an upper hook to cooperate with the edge of the A side; the edge of the lower locking edge is provided with a lower hook to cooperate with the edge of the C side, the cooperation is reliable and not easy to loosen, so as to ensure that the lateral card slot and the frame are reliably fixed.

[0019] 3. The upper hook and the lower hook are curled edges that bend inward. The curled edges cooperate with the edges of side A and side C through curling. After cooperation, a large force is generated and it is not easy to loosen.

[0020] 4. An intermediate wall is provided between the two lateral slots and is embedded between the frames of two adjacent photovoltaic modules. The side of the frame can press against the intermediate wall to achieve seamless embedding.

[0021] 5. The engaging portion is a card hole, and the bottom card buckle passes through the card hole. Since the bottom card buckle is an inverted umbrella-shaped structure, the inverted umbrella-shaped structure shrinks and deforms toward the middle during the process of passing through the card hole, so it is easy to pass through the card hole. After passing through the card hole, the inverted umbrella-shaped structure expands outward and finally cooperates with the lower edge of the card hole to achieve card fixing. No tools are required during the installation process, which is convenient for quick installation.

[0022] 6. The crossbeam is a C-shaped steel or a U-shaped steel, with its mouth facing upward and a clip hole provided on the bottom wall of the crossbeam. Thus, the bottom clip passes through the mouth of the crossbeam through the inner side of the crossbeam and finally passes through the clip hole. While the lower clip edge is supported on the upper surface of the crossbeam, the lower clip edge cooperates with the bottom clip to be fixed on the crossbeam.

[0023] 7. Since the waterproof buckle is an integrated structural profile, such as an aluminum alloy profile, it can be extruded to achieve industrial production, significantly reduce costs, and has high strength and long service life.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0035] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0036] Reference Figures 1 to 4As shown, a snap-fit ​​photovoltaic assembly fixing structure includes a plurality of beams 3 arranged side by side in the longitudinal direction, and a photovoltaic assembly 2 is mounted on the beam 3 and fixed by a waterproof pressure block 1. The photovoltaic assembly has a frame 21, and the frame 21 is mounted above the beam 3. The waterproof pressure block 1 includes a bottom buckle 11 located at the bottom and a lateral card slot 12 arranged above the bottom buckle. A snap-fitting portion is provided on the beam 3, and the bottom buckle 11 snaps with the snap-fitting portion, and the frame 21 snaps into the lateral card slot 12. Since the waterproof pressure block is provided between two adjacent photovoltaic assemblies, lateral card slots 12 are provided on opposite sides of the waterproof pressure block, and an intermediate wall 125 is provided between the two lateral card slots and is embedded between the frames of the two adjacent photovoltaic assemblies. The side of the frame can press against the intermediate wall to achieve seamless embedding.

[0037] First, the waterproof pressure block is engaged with the engaging part on the beam through the bottom buckle, so that the waterproof pressure block can be fixed on the beam, and then the photovoltaic module is installed. First, the frame of the photovoltaic module on one side of the waterproof pressure block is pushed and engaged in the lateral groove on that side for locking and fixing, and then the frame of the photovoltaic module on the other side of the waterproof pressure block is pushed and engaged in the lateral groove on the other side for locking and fixing. The entire installation process does not require the use of fasteners such as bolts. Compared with the existing waterproof pressure block fastened with bolts, it is simple and easy to operate, and the installation efficiency is improved. Since no bolts are required and the amount of pressure blocks used is small, the cost can be reduced.

[0038] Secondly, the waterproof pressure block is embedded between two adjacent photovoltaic modules, and the lateral slot covers the frame of the photovoltaic module, leaving no gaps to play a waterproof role. There is no need to set up waterproof blocking strips, thus solving the seamless installation requirements of photovoltaic systems on flat roofs, especially sloping roofs, and reducing leakage problems.

[0039] Specifically, the bottom of the frame 21 is provided with a C edge 212, the top is provided with an A edge 211, and the lateral slot 12 is provided with an upper engaging edge 123 engaged with the A edge and a lower engaging edge 121 engaged with the C edge. The edge of the upper engaging edge 123 is provided with an upper hook 124, and the edge of the lower engaging edge 121 is provided with a lower hook 122, and the upper hook 124 cooperates with the edge of the A edge, and the lower hook 122 cooperates with the edge of the C edge. Since the width of the A edge 211 is smaller than the width of the C edge 212, correspondingly, the width of the upper hook 124 is smaller than the width of the lower hook 122. The waterproof pressure block is reliable through cooperation with the edge of the A edge and the edge of the C edge, and is not easy to loosen. Specifically, the upper hook and the lower hook are curled edges bent inward.

[0040] In this embodiment, the engaging portion is a locking hole 31, and the bottom buckle 11 passes through the locking hole. As long as the bottom buckle is aligned with the locking hole and the waterproof pressure block is pressed downward, the bottom buckle is deformed and passes through the locking hole, and then the bottom buckle is restored to its original state, it can be fixed with the locking hole, which is convenient for installation. Specifically, the bottom buckle 11 is an inverted umbrella-shaped structure with multiple barbs distributed along the circumference. During the process of passing through the locking hole, the inverted umbrella-shaped structure shrinks and deforms toward the middle, so it is easy to pass through the locking hole. After passing through the locking hole, the inverted umbrella-shaped structure expands outward and finally cooperates with the lower edge of the locking hole to achieve locking and fixing. No tools are required during the installation process, which is convenient for quick installation.

[0041] The crossbeam 3 is a U-shaped or C-shaped structure, with its mouth facing upward, and the clamping hole 31 is provided on the bottom wall of the crossbeam. Therefore, the bottom clamp passes through the inside of the crossbeam through the mouth of the crossbeam and finally passes through the clamping hole, and while the lower clamping edge is supported on the upper surface of the crossbeam, the lower clamping edge cooperates with the bottom clamp to be fixed on the crossbeam.

[0042] It can be understood that the matching structure between the bottom buckle and the engaging part on the beam is not limited to the methods of the above-mentioned embodiments. For example, the bottom buckle is a claw with elastic walls on both sides, and the engaging part is the clamping ribs on both sides of the beam. After the claw is inserted into the inner side of the beam, it restores its original shape and cooperates with the clamping rib to complete the fixation.

[0043] Preferably, the waterproof pressing block 1 is a profile of an integrated structure, such as an aluminum alloy profile, which is extruded to achieve industrialized production, significantly reduce costs, and has high strength and long service life.

[0044] The photovoltaic system is provided with the above-mentioned snap-fit ​​photovoltaic component fixing structure. In addition to the above-mentioned photovoltaic component fixing structure, the entire photovoltaic system also has other parts. The cross beams are cross-fixed on the longitudinal beams. In addition, a drainage structure is also provided. Please refer to the existing technology for the structure of other parts and will not be repeated here.

[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
