Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic component installation, and in particular to a gapless installation structure of a photovoltaic component. Background Art

[0002] With the development of clean energy, solar photovoltaic projects have been increasingly used. When setting up a solar photovoltaic project, the photovoltaic modules need to be installed on the open ground, roof and other environments through frames.

[0003] At present, when installing photovoltaic modules, they are generally fixed to frame structures such as beams using pressure blocks, bolts, nuts, etc. First, the photovoltaic module needs to be placed on the beam, then the pressure block is placed on the edge of the photovoltaic module, and finally the pressure block is pressed onto the beam with bolts and nuts, so that the photovoltaic module is pressed on the beam, thereby fixing the photovoltaic module. However, the existing photovoltaic module pressing and fixing installation structure makes the gap between each photovoltaic module too large, generally more than 20mm, which not only reduces the installed capacity of the module, but also leads to high bracket costs; at the same time, with land resources becoming increasingly scarce today, a lot of land resources are wasted. Summary of the invention

[0004] The present invention provides a photovoltaic module gapless mounting structure, which is used to reduce the gap between photovoltaic modules while ensuring the fixing strength, thereby increasing the installed capacity of photovoltaic modules. The photovoltaic module gapless mounting structure includes a photovoltaic module, a crossbeam and a locking mechanism, wherein:

[0005] The plurality of photovoltaic modules are arranged closely in sequence without gaps, the plurality of crossbeams are arranged at the bottom of each photovoltaic module along the middle seam between each two adjacent photovoltaic modules, and each crossbeam is connected to the bottom frame of each two adjacent photovoltaic modules through at least one locking mechanism;

[0006] The locking mechanism includes a support plate, two pry bars and a fixing member: the support plate is placed between the bottom frame of the photovoltaic component and the crossbeam, with both ends protruding out of the crossbeam; the two pry bars are movably connected to the two ends of the support plate and can rotate and move relative to the support plate, and the top of each pry bar can rotate and move to the inner side of the bottom frame of the photovoltaic component to engage with the photovoltaic component; the fixing member can be respectively connected to the tail of the two pry bars after the two pry bars are engaged with the photovoltaic component to limit the position, thereby fixing the photovoltaic component to the top of the crossbeam.

[0007] In a specific implementation, the two pry bars are hinged to the two ends of the support plate through a hinge shaft.

[0008] In a specific implementation, the pry bar uses the hinge point as a fulcrum, and the force arm at the tail is greater than the force arm at the top.

[0009] In a specific implementation, the shape of the top of the pry bar matches the shape of the inner side of the bottom frame of the photovoltaic module.

[0010] In a specific implementation, the fixing member is a bolt fixing member, and the tails of the two pry bars and the cross beam are provided with bolt holes matching the bolt fixing member. The bolt fixing member can sequentially cross the bolt holes and be detachably connected to the two pry bars and the cross beam through nuts.

[0011] In a specific implementation, the bottom frame on one side of each photovoltaic module is connected to the crossbeam through two locking mechanisms.

[0012] In a specific implementation, the crossbeam is a C-shaped steel crossbeam.

[0013] In a specific implementation, the tail of the pry bar is parallel to the web of the C-shaped steel beam when the locking mechanism is in a locked state.

[0014] The photovoltaic module gapless installation structure provided by the present invention comprises a photovoltaic module, a beam and a locking mechanism, wherein a plurality of photovoltaic modules are arranged closely and gaplessly on the top of a plurality of beams in sequence, each beam is arranged along the middle seam of each two adjacent photovoltaic modules, and is connected to the bottom frame of the two adjacent photovoltaic modules through a locking mechanism; the locking mechanism comprises a support plate, two pry bars and a fixing member: the support plate is placed between the photovoltaic module and the beam and the two ends protrude out of the beam; the two pry bars are movably connected to the two ends of the support plate and can rotate relative to the pry bars, and the top of each pry bar can be rotated and moved to the inner side of the bottom frame of the photovoltaic module and locked; the fixing member can be respectively connected to the tail of the two pry bars after the two pry bars are locked to limit the position, thereby locking the relative position of the photovoltaic module and the beam. Aiming at the existing large-gap photovoltaic module installation structure, the structure creatively utilizes the labor-saving lever principle to lock and connect the two adjacent photovoltaic modules, greatly reduces the installation gap between the two adjacent photovoltaic modules, improves the installed capacity of the photovoltaic module, and thereby reduces the bracket cost; at the same time, the fixed installation structure using the lever principle also has high working reliability and safety.

[0020] In order to make the purpose, technical solution and advantages of the specific implementation of the present invention more clear, the specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings. Here, the schematic specific implementation of the present invention and its description are used to explain the present invention, but are not intended to limit the present invention.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a photovoltaic module gapless installation structure, which is used to reduce the photovoltaic module gap while ensuring the fixing strength, thereby increasing the installed capacity of the photovoltaic module. The photovoltaic module gapless installation structure includes a photovoltaic module 100, a beam 200 and a locking mechanism 300, wherein:

[0022] The plurality of photovoltaic modules 100 are arranged closely in sequence without gaps, and the plurality of crossbeams 200 are arranged at the bottom of each photovoltaic module 100 along the middle seam between each two adjacent photovoltaic modules 100, and each crossbeam 200 is connected to the bottom frame 110 of each two adjacent photovoltaic modules 100 through at least one locking mechanism 300;

[0023] The locking mechanism 300 includes a support plate 310, two pry bars 320 and a fixing member 330: the support plate 310 is placed between the bottom frame 110 of the photovoltaic component 100 and the beam 200, with both ends protruding out of the beam 200; the two pry bars 320 are movably connected to the two ends of the support plate 310 and can rotate and move relative to the support plate 310, and the top of each pry bar 320 can rotate and move to the inner side of the bottom frame 110 of the photovoltaic component 100 to engage with the photovoltaic component 100; the fixing member 330 can be respectively connected to the tail of the two pry bars 320 after the two pry bars 320 are engaged with the photovoltaic component 100 to limit the position, thereby fixing the photovoltaic component 100 to the top of the beam 200.

[0024] In a specific implementation, the movable connection between the pry bar 320 and the support plate 310 can have multiple implementation schemes, for example, Figure 3 , Figure 4As shown, in order to ensure a firm connection and improve the working stability of the structure, the two pry bars 320 can be hinged to the two ends of the support plate 310 through a hinge shaft 340.

[0025] In a specific implementation, there are many implementation schemes for setting the hinge position of the pry bar 320. Figure 3 , Figure 4 As shown, in order to improve the installation firmness and reliability of the mechanism, the tail length of the pry bar 320 can be greater than the top length, that is, the pry bar 320 uses the hinge point as a fulcrum, and the force arm of the tail is greater than the force arm of the top, thereby effectively ensuring the installation firmness.

[0026] In a specific implementation, the shape of the top of the pry bar 320 and the shape of the bottom frame 110 of the photovoltaic module 100 can be arranged in a variety of embodiments. Figure 3 , Figure 4 As shown, the shape of the top of the pry bar 320 can match the shape of the inner side of the bottom frame 110 of the photovoltaic module 100. Furthermore, the shape of the top of the pry bar 320 and the shape of the inner side of the bottom frame 110 of the photovoltaic module 100 can both be L-shaped, thereby effectively ensuring that the top of the pry bar 320 is engaged with the bottom frame 110 of the photovoltaic module 100, avoiding the photovoltaic module 100 from shifting up and down after installation. When setting, the top of the pry bar 320 (i.e., the short arm end) has a plane that can be pressed against the inner side of the frame of the photovoltaic module 100, and the surface contact increases the upper limit of the applied fixing force, which is safer and more reliable.

[0027] In a specific implementation, the fixing member 330 can be selected in a variety of embodiments when it is set. Figure 3 , Figure 4 As shown, in order to ensure reliable fixation and reduce installation costs, the fixing member 330 can be a bolt fixing member 330, and the tails of the two pry bars 320 and the cross beam 200 can be provided with bolt holes matching the bolt fixing member 330. The bolt fixing member 330 can sequentially cross the bolt holes and be detachably connected to the two pry bars 320 and the cross beam 200 through nuts 331. When set, at least four nuts 331 can be provided on the bolt fixing member 330, one part of which is used for positioning the secondary beam, and the other part is used for fastening the two screw rods.

[0028] In a specific implementation, there may be multiple implementation schemes for setting the number of locking mechanisms 300. For example, in order to ensure a firm connection while reducing costs, a side frame of each photovoltaic module 100 may be connected to the crossbeam 200 at two points, that is, the bottom frame 110 of one side of each photovoltaic module 100 may be connected to the crossbeam 200 via two locking mechanisms 300.

[0029] In a specific implementation, the arrangement of the crossbeam 200 may have a variety of implementation schemes, for example, Figure 2 , Figure 3 and Figure 4 As shown, in order to reduce production costs while ensuring the bearing capacity of the crossbeam 200 , the crossbeam 200 may be a C-shaped steel crossbeam 200 .

[0030] In a specific implementation, there are many implementation schemes for setting the rear end position of the pry bar 320 after locking, for example, Figure 3 As shown, in order to ensure a firm connection between the pry bar 320 and the fixing member 330 , the tail of the pry bar 320 can be parallel to the web of the C-shaped steel beam 200 when the locking mechanism 300 is in a locked state.

[0031] In summary, the photovoltaic assembly gapless installation structure provided by the present invention includes a photovoltaic assembly 100, a beam 200 and a locking mechanism 300, wherein a plurality of photovoltaic assemblies 100 are sequentially and closely arranged on the top of a plurality of beams 200 without gaps, each beam 200 is arranged along the middle seam of each adjacent photovoltaic assembly 100, and is connected to the bottom frame 110 of the two adjacent photovoltaic assemblies 100 through the locking mechanism 300; the locking mechanism 300 includes a support plate 310, two pry bars 320 and a fixing member 33 0: The support plate 310 is placed between the photovoltaic module 100 and the cross beam 200, and the two ends of the support plate 310 protrude out of the cross beam 200; two pry bars 320 are movably connected to the two ends of the support plate 310 and can rotate relative to the pry bars 320, and the top of each pry bar 320 can be rotated and moved to the inner side of the bottom frame 110 of the photovoltaic module 100 and locked; the fixing member 330 can be connected to the tail of the two pry bars 320 respectively after the two pry bars 320 are locked to limit the position, thereby fixing the relative position of the photovoltaic module 100 and the cross beam 200. This structure is aimed at the existing large-gap photovoltaic module installation structure, and creatively uses the labor-saving lever principle to fix two adjacent photovoltaic modules 100, which greatly reduces the installation gap between the two adjacent photovoltaic modules 100, improves the installed capacity of the photovoltaic module 100, and thus reduces the bracket cost; at the same time, the fixed installation structure using the lever principle also has high working reliability and safety.
