Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a clamp, a photovoltaic mechanism, and a rooftop power generation system. Background Technology

[0002] Due to the advantages of prefabrication of steel structure components in factories, light weight, quick installation, and short construction cycle, steel structure technology has attracted widespread attention. More and more industrial and civil buildings are beginning to use profiled steel sheets in their building envelopes, such as roofs and walls.

[0003] In practical applications, by installing additional functional layers on the outer surface of metal profiled steel sheet enclosures, the aesthetics of buildings can be enhanced, and additional functions can be added. This has attracted increasing attention from the market. However, in the photovoltaic field, metal profiled steel sheets are rarely combined with photovoltaic structures.

[0004] Chinese patent document CN202311278689.X discloses a photovoltaic component, including a color steel tile and a photovoltaic module. Two adjacent color steel tiles are connected by a clamp. The photovoltaic module is located on one side of the color steel tile and connected to the clamp. The photovoltaic module includes a laminate and a frame. The frame includes a mounting groove. A part of the laminate can extend into the mounting groove. The clamp includes a first clamping part and a second clamping part. Along the thickness direction of the photovoltaic module, there is a clamping space between the first clamping part and the second clamping part. One end of the laminate with the frame can extend into the clamping space.

[0005] Although it involves the combination of photovoltaic modules and metal profiled steel sheets, the variety and quantity of installation parts make construction inconvenient. When using clamps to fix photovoltaic modules and metal profiled steel sheets, the force transmission path is unclear and the fixing effect is limited, which can easily cause photovoltaic modules to detach from the profiled steel sheets.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The technical problem to be solved by this utility model is to solve the problem of poor installation effect between photovoltaic modules and metal profiled steel sheets.

[0008] This utility model solves the above-mentioned technical problems through the following technical means:

[0009] This utility model claims a protective clamp, including a first clamping block, a second clamping block and a tightening unit. The second clamping block is arranged above the first clamping block. The middle parts of the second clamping block and the first clamping block are close to each other and locked together by the tightening unit. The ends of the first clamping block and the second clamping block are far apart from each other and extend to both sides. The end of the first clamping block and the middle part of the first clamping block enclose a first space.

[0010] This utility model claims protection by setting a first clamping block and a second clamping block, wherein the middle parts of the second clamping block and the first clamping block are close together, and the two ends of the first clamping block and the second clamping block are far apart from each other, so that the two ends of the second clamping block and the first clamping block form a position for placing the object to be clamped; combined with a screwing unit set in the middle of the second clamping block and the first clamping block, the distance between the second clamping block and the first clamping block can be adjusted to realize the clamping and loosening of the object to be clamped, which is convenient for disassembly and assembly, and the force transmission path between the second clamping block and the first clamping block and the object to be clamped is clear, the fixation is very stable, and it is not easy to detach.

[0011] Preferably, the tightening unit is a locking bolt, and the middle of the second clamping block and the first clamping block are respectively provided with screw holes, and the locking bolt is engaged in the screw holes.

[0012] Furthermore, by twisting the locking bolt, it engages with the screw hole, thereby adjusting the distance between the second clamping block and the first clamping block.

[0013] Preferably, the end of the first clamping block is hooked upwards.

[0014] The hook shape allows the first clamping block to lock with the object to be clamped when it is pressed down. This not only tightly clamps the object to be clamped, preventing adjacent components from accidentally falling off, but also ensures the sealing of the clamping part.

[0015] Preferably, the end of the second clamping block is hooked downwards.

[0016] Similarly, the end of the second clamping block can lock the object to be clamped, and the end of the first clamping block and the end of the second clamping block are combined to lock and squeeze with the screwing unit, so that the object to be clamped is stably clamped.

[0017] This utility model also claims a photovoltaic mechanism using the clamp, which includes at least two metal plates, the clamp and at least two photovoltaic modules. The metal plates are concave in the middle, and both ends of the metal plates are bent upward to form a first bending portion. The first bending portion is bent inward to form a first recessed portion, and then bent upward to form a second bending portion.

[0018] At least two metal plates are joined together along the length direction, adjacent second bends are engaged with each other and embedded together in the first space, the end of the first clamping block is engaged with the corresponding first recess, the first turning part, the middle part of the first clamping block and the middle part of the second clamping block and the end of the second clamping block together enclose the second space, and the photovoltaic module is inserted into the second space.

[0019] The photovoltaic mechanism uses clamps to fix the photovoltaic modules to the metal plate. The entire clamp only uses the clamping force between the first and second clamping blocks to fix the photovoltaic modules to the metal plate. This not only reduces the types and number of parts used, but also makes assembly and disassembly quick and convenient. In addition, the force transmission path is clear and direct, resulting in a significant fixing effect and improving construction efficiency.

[0020] Preferably, the second bend at the left end of the metal plate is defined as the second outer bend, and the second outer bend bends outward to form an inverted U-shaped structure;

[0021] The second bend at the right end of the metal plate is defined as the second inner bend. The second inner bend bends inward to form an inverted U-shaped structure. When at least two metal plates are joined together, the second inner bend engages with the second outer bend.

[0022] The second inner bend engages with the second outer bend to achieve the splicing of adjacent metal plates.

[0023] This utility model also claims a roof power generation system using the photovoltaic mechanism, which includes a roof structure layer, purlins, a first connecting mechanism, side supports, and a photovoltaic mechanism. Purlins are laid on the roof structure layer, and side supports are set on the purlins through the first connecting mechanism. The top of the side supports is embedded between adjacent second bends.

[0024] The rooftop power generation system uses clamps to perfectly combine photovoltaic modules with metal panels, preserving the structural rigidity of the photovoltaic modules and applying a reaction force to the metal panels and the attached enclosure structure, thereby improving the load-bearing capacity and wind resistance of the rooftop power generation system.

[0025] Preferably, the second bend at the left end of the metal plate is defined as the second outer bend, and the second outer bend bends outward to form an inverted U-shaped structure;

[0026] The second bend at the right end of the metal plate is defined as the second inner bend. The second inner bend bends inward to form an inverted U-shaped structure. When at least two metal plates are joined together, the second inner bend engages with the second outer bend.

[0027] The top of the side bracket has a third bend that has the same outline as the second outer bend. The third bend fits between the second inner bend and the second outer bend.

[0028] The third bend engages between the second inner bend and the second outer bend, thus securing the metal plate and the purlin.

[0029] Preferably, it also includes a central support and a second connecting mechanism, wherein the metal plate protrudes upward in the middle to form a support portion, and the support portion is fixed to the purlin through the second connecting mechanism.

[0030] Furthermore, the support unit works in conjunction with the central bracket to improve the fixation of the metal plate and purlin.

[0031] Preferably, the top of the middle support has an inverted triangular structure, and the outer contour of the top of the middle support matches the inner contour of the support part.

[0032] Furthermore, the outer contour of the top of the central bracket matches the inner contour of the support section, improving the connection stability of the metal plate and purlin. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0048] Embodiment 1

[0049] Refer to Figure 1 , this embodiment claims to protect a fixture, including a first clamping block 410, a second clamping block 411, and a screwing unit 412.

[0050] The first clamping block 410 has a "U" - shaped structure. The second clamping block 411 is arranged above the first clamping block 410. The second clamping block 411 has an inverted "U" - shaped structure. In this way, the middle parts of the second clamping block 411 and the first clamping block 410 are close to each other, but the two ends of the first clamping block 410 and the second clamping block 411 are far away from each other and extend to both sides. The end part and the middle part of the first clamping block 410 enclose a first space.

[0051] The first space refers to the recess of the "U" - shaped structure.

[0052] Furthermore, the end part of the first clamping block 410 is in an upward - hooked shape, and the end part of the second clamping block 411 is in a downward - hooked shape. Taking the upward - hooked shape as an example, the hooked shape means that the end part of the first clamping block 410 forms a protrusion upward. The downward - hooked shape is the same and will not be elaborated further.

[0053] In practical applications, the shapes of the first clamping block 410 and the second clamping block 411 are not limited to the "U" - shape. The side can also be stepped. Taking the first clamping block 410 as an example, it only needs to ensure that there is a height difference between the middle part and the end part of the first clamping block 410, and the middle part of the first clamping block 410 is concave to form the first space. [[ID=XX]]

[0054] The middle parts of the second clamping block 411 and the first clamping block 410 are locked by the screwing unit 412. In fact, the screwing unit 412 is used to screw the middle parts of the second clamping block 411 and the first clamping block 410, so as to adjust the distance between the end parts of the second clamping block 411 and the first clamping block 410. Specifically, the screwing unit 412 is preferably a locking bolt. Corresponding screw holes are provided in the middle parts of the second clamping block 411 and the first clamping block 410, and the locking bolt is engaged in the screw holes.

[0055] Embodiment 2

[0056] Refer to Figure 2 and Figure 3This embodiment requires protection of a photovoltaic mechanism, including at least two metal plates, clamps, and at least two photovoltaic modules 42. The photovoltaic mechanism uses clamps to splice two adjacent photovoltaic modules 42 and two adjacent metal plates to achieve the installation and fixation of the metal plates and photovoltaic modules 42.

[0057] Specifically, the photovoltaic module 42 is above the metal plate. The longitudinal cross-section of the metal plate has an inverted trapezoidal structure. Specifically, the middle of the metal plate is concave, and both ends of the metal plate are bent upward to form a first bending part 401. The first bending part 401 is bent inward to form a first recessed part 402, and then bent upward to form a second bending part.

[0058] Since two adjacent metal plates need to be joined together, the second bends at both ends of the adjacent metal plates need to be joined together, which means that the shapes of the second bends at both ends of the metal plates can be joined together.

[0059] Therefore, the second bend at the left end of the metal plate is defined as the second outer bend 404, and the second outer bend 404 bends outward to form an inverted U-shaped structure;

[0060] The second bend at the right end of the metal plate is defined as the second inner bend 403. The second inner bend 403 bends inward to form an inverted U-shaped structure. When at least two metal plates are joined together, the second inner bend 403 is engaged with the second outer bend 404.

[0061] In practical applications, the second inner bend 403 and the second outer bend 404 are not limited to this shape, and the shapes of the two ends of the metal plate can be interchanged, as long as the two adjacent second bends are spliced ​​together.

[0062] At least two metal plates are joined together along the length direction, adjacent second bends are engaged with each other and are embedded together in the first space, the end of the first clamping block 410 is engaged with the corresponding first recess 402, the first turning part 401, the middle part of the first clamping block 410 and the middle part of the second clamping block 411 and the end of the second clamping block 411 together form a second space, and the photovoltaic module 42 is inserted into one side of the second space.

[0063] At this point, any two adjacent metal plates and adjacent photovoltaic modules 42 can be spliced ​​together by clamps to form a whole.

[0064] It is worth mentioning that the photovoltaic modules 42 commonly found on the market include frameless photovoltaic modules 42 and framed photovoltaic modules 42. Regardless of which type, they can be fixed in the manner described in this embodiment.

[0065] Example 3

[0066] See Figure 4 and Figure 5 and Figure 6This embodiment requires protection of the roof power generation system, including the roof structural layer, purlins 1, a first connecting mechanism 2, side brackets 3, a photovoltaic mechanism, a central bracket 5, and a second connecting mechanism 6. The photovoltaic mechanism from Embodiment 2 is installed on the roof structural layer. Specifically, purlins 1 are laid on the roof structural layer, and side brackets 3 are set on the purlins 1 through the first connecting mechanism 2. A third bend 30 protrudes from the top of the side bracket 3. The third bend 30 has the same outline as the second outer bend 404, and the third bend 30 is engaged between the second inner bend 403 and the second outer bend 404.

[0067] Furthermore, in order to strengthen the connection between the purlin 1 and the metal plate, preferably, the middle part of the metal plate protrudes upward to form a support part 405, the top of the middle bracket 5 has an inverted triangular structure, the outer contour of the top of the middle bracket 5 matches the inner contour of the support part 405, and the support part 405 and the purlin 1 are fixed by the second connecting mechanism 6.

[0068] Among them, the first connecting mechanism 2 and the second connecting mechanism 6 are preferably connecting bolts. Taking the first connecting mechanism 2 as an example, the side bracket 3 and the purlin 1 are respectively opened with connecting screw holes, and the connecting bolts are screwed into the connecting screw holes for fixation. The second connecting mechanism 6 will not be described in detail.

[0069] The process of generating electricity after the rooftop power generation system is assembled is as follows:

[0070] First, install the side bracket 3 and the middle bracket 5 on the purlin 1.

[0071] Next, two adjacent metal plates are installed. The middle bracket 5 passes through the support part 405. The second inner bend part 403, the third bend part 30, and the second outer bend part 404 are sequentially fitted and then bent at the rear end. The clamp is inserted from one side, so that the second outer bend part 404 is inserted into the first space. The two ends of the first clamping block 410 are respectively inserted into the first recessed part 402 of the two adjacent metal plates.

[0072] Then, install two adjacent photovoltaic modules 42, place one side of each adjacent photovoltaic module 42 in the second space, and twist and tighten the unit 412 so that the first clamping block 410 and the second clamping block 411 come closer to each other. Finally, the end of the second clamping block 411 presses the corresponding photovoltaic module 42 onto the first turning part 401.

[0073] Finally, following the above method, a complete rooftop power generation system is formed.

[0074] This embodiment aims to protect the roof power generation system by using clamps to perfectly combine the photovoltaic module 42 with the metal plate, preserving the structural rigidity of the photovoltaic module 42 to react on the metal plate and the attached enclosure structure, thereby improving the load-bearing capacity and wind resistance of the roof power generation system.

[0075] The entire fixture uses only the clamping force between the first clamping block 410 and the second clamping block 411 to fix the photovoltaic module 42 to the metal plate. Not only are there fewer types and quantities of parts used, but assembly and disassembly are also quick and convenient. Moreover, the force transmission path is clear and direct, the fixing effect is obvious, and construction efficiency is improved.

[0076] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
