Description

[0002] Photovoltaic panels as roofs of buildings can not only make full use of sunlight to generate electricity, but also help reduce the indoor temperature of buildings. Using photovoltaic panels as roofs of buildings requires photovoltaic panels to have good waterproof performance. With the rapid development of the photovoltaic industry, companies in the industry are pursuing the development of low-cost and high-reliability photovoltaic products.

[0003] The existing V-shaped waterproof bracket for photovoltaic panels adopts a structure that uses a V-groove support block and a traditional middle / side first pressure code to fix and install the longitudinal drainage keel, panel unit and support keel. On the one hand, the use of a medium pressure code to fix the panel unit will result in a larger gap between adjacent panel units, and a large amount of water flowing into the longitudinal drainage keel. It is often necessary to set a water retaining cover plate above the medium pressure code to reduce the water flow flowing into the V-shaped waterproof bracket, which increases the cost. In addition, the water retaining cover plate is difficult to fix firmly and can be easily blown away, further affecting the waterproof effect of the product. On the other hand, when the panel unit is fixed with a medium pressure code, a single medium pressure code is locked with the support block at each node to achieve the compression of the two panel units. The support block is easy to bend and deform, thereby generating vibration, and there is a risk that the first pressure code bolts will vibrate and loosen, and the panel unit fixation will fail.

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figures 1 to 12 As shown, this embodiment provides an embodiment of a photovoltaic waterproof bracket, including a longitudinal drainage keel 1, a transverse drainage keel 2, a panel unit 3 and a locking assembly, wherein a first water guide groove 11 is provided on the top of the longitudinal drainage keel 1, and support plates 12 are provided on both sides of the first water guide groove 11, and the transverse drainage keel 2 is mounted on the support plates 12 of two adjacent longitudinal drainage keels 1, and a second water guide groove 21 is provided on the top of the transverse drainage keel 2, and the second water guide groove 21 is communicated with the first water guide groove 11; the locking assembly includes a supporting block 4, a first pressure code 5, a first connecting column 6, and a second connecting column 7, and the supporting block 4 is arranged along the The longitudinal drainage keel 1 is arranged in the extension direction, the supporting block 4 spans the first water guide groove 11 and is fixedly connected to the longitudinal drainage keel 1 through the first connecting column 6, and at least two convex ribs 41 are provided on the top of the supporting block 4; the panel unit 3 is provided with adjacently arranged transverse side frames 31 and longitudinal side frames 32, the transverse side frames 31 extend into the second water guide groove 21, and the longitudinal side frames 32 are provided on the top of the supporting block 4, the first pressing code 5 is connected to the convex rib 41 through the second connecting column 7, and abuts against the longitudinal side frame 32, and the axial direction of the second connecting column 7 is parallel to the extension direction of the transverse drainage keel 2.

[0040] In this embodiment, a supporting block 4 is arranged across the first water guide groove 11 on the longitudinal drainage keel 1, so that the supporting block 4 is fixedly connected to the longitudinal drainage keel 1 through the first connecting column 6, so that the transverse drainage keel 2 is laid on the support plate 12 of two adjacent longitudinal drainage keels 1, and the second water guide groove 21 of the transverse drainage keel 2 is communicated with the first water guide groove 11, so that the transverse side frame 31 of the panel unit 3 extends into the second water guide groove 21, and the longitudinal side frame 32 of the panel unit 3 is arranged on the top of the supporting block 4, and the longitudinal side frame 32 of the panel unit 3 is connected to the transverse drainage keel 2 through the axial direction. The second connecting column 7 parallel to the extension direction of the water keel 2 fixes the first pressing code 5 with the convex rib 41 on the top of the supporting block 4, so that the first pressing code 5 and the top of the longitudinal side frame 32 can realize the fixation of the panel unit 3 and the longitudinal drainage keel 1, and at the same time realize the positioning and assembly of the transverse drainage keel 2 on the longitudinal drainage keel 1; since the structure of the fixed panel unit 3 hardly occupies the plane laying space of the panel unit 3, the panel unit 3 can almost completely cover the longitudinal drainage keel 1 and the transverse drainage keel 2, reducing the entry into the longitudinal drainage keel. The water flow toward the drainage keel 1 and the transverse drainage keel 2 does not need to be additionally provided with a water retaining cover to reduce the water flow into the longitudinal drainage keel 1 and the transverse drainage keel 2, thereby reducing the cost and avoiding the risk of the drainage cover being blown away, and the reliability of the waterproof structure is higher; in addition, the panel unit 3 is fixed on the supporting block 4 by the pressure of the first pressure code 5, and the second connecting column 7 connecting and fixing the supporting block 4 and the first pressure code 5 has an axial direction parallel to the extension direction of the transverse drainage keel 2. Under extreme weather conditions, on the one hand, when the panel unit 3 drives the first pressure code 5 and the supporting block 4 to vibrate up and down, the second connecting column 7 is not easy to vibrate and loosen, thereby reducing the risk of failure of the panel unit 3 to be fixed. On the other hand, the second connecting column 7 is mainly subjected to the upward shear force transmitted by the first pressure code 5 and the supporting block 4. Compared with the existing medium pressure code 5 fixing the panel unit 3, the medium pressure bolt is mainly subjected to axial tension. The shear bearing capacity of the second connecting column 7 is stronger than the tensile bearing capacity, so the reliability of the photovoltaic waterproof bracket installation structure is stronger under extreme conditions.

[0041] In this embodiment, the first connecting column 6 and the second connecting column 7 are preferably bolts, and the supporting block 4 and the first pressing code 5 are preferably formed by extrusion of aluminum alloy.

[0042] To facilitate comparison of the difference between the shear bearing capacity and the tensile bearing capacity of the second connecting column 7, taking the M8 bolt as an example, the shear bearing capacity of the bolt is 1.3 times the tensile bearing capacity.

[0043] In this embodiment, each panel unit 3 is compressed by the shear force between the second connecting column 7 and the first pressing code 5 and the convex rib 41, thereby further enhancing the waterproofness and connection reliability of the product without increasing the cost.

[0044] Specifically, combined Figure 3In this embodiment, the panel unit 3 is provided with an assembly cavity with a bottom opening, and the transverse side frame 31 and the longitudinal side frame 32 are arranged on adjacent sides of the assembly cavity. The transverse side frame 31 includes a first folded edge 311 and a second folded edge 312 connected to the first folded edge 311, the first folded edge 311 is arranged parallel to the side wall of the second water guide groove 21, the second folded edge 312 is arranged at the bottom of the panel unit 3 and is located on the side of the first folded edge 311 close to the assembly cavity, and the second folded edge 312 is arranged at the bottom of the second water guide groove 21. The second folded edge 312 is preferably formed by folding the first folded edge 311 into the assembly cavity.

[0045] Combination Figure 6 and Figure 7 The longitudinal side frame 32 includes a third folded edge 321 and a fourth folded edge 322 connected to the third folded edge 321, the third folded edge 321 is arranged parallel to the rib 41, the fourth folded edge 322 is arranged at the bottom of the panel unit 3 and is located on the side of the third folded edge 321 close to the assembly cavity, the fourth folded edge 322 is arranged on the top surface of the supporting block 4, the first pressing code 5 extends into the assembly cavity and abuts against the top surface of the fourth folded edge 322. The fourth folded edge 322 is preferably formed by folding the third folded edge 321 into the assembly cavity.

[0046] The panel unit 3 of this embodiment includes at least one of a photovoltaic panel unit and an operation and maintenance panel unit. To facilitate the operation and maintenance of the photovoltaic panel, the operation and maintenance panel unit is arranged in a longitudinal arrangement and is generally arranged between two photovoltaic panel units.

[0047] Combination Fig.10 The first pressing code 5 of this embodiment specifically includes a pressing arm 51 and a connecting arm 52 that are arranged opposite to each other, a buckle groove 53 is formed between the pressing arm 51 and the connecting arm 52, the convex rib 41 extends into the buckle groove 53, the connecting arm 52 is connected to the convex rib 41 through the second connecting column 7, and the pressing arm 51 abuts against the longitudinal side frame 32, specifically abuts against the top surface of the fourth folded edge 322. The cross-sectional area of ​​the end of the pressing arm 51 gradually increases to increase the effective area of ​​pressing on the longitudinal side frame 32.

[0048] Combination Figures 6 to 9 In order to facilitate the arrangement and installation of the supporting block 4 along the extension direction of the longitudinal drainage keel 1 and to strengthen the firmness of the connection between the supporting block 4 and the longitudinal drainage keel 1 in the vertical direction, the supporting block 4 structure of this embodiment is provided with a slide groove 42 adapted to the support plate 12.

[0049] The supporting block 4 of this embodiment spans across the first water channel 11 , and is fixedly connected to the supporting plate 12 of the longitudinal drainage keel 1 via the first connecting column 6 .

[0050] Specifically, the first connecting column 6 extends from the bottom of the supporting block 4 into the slide groove 42 and abuts against the support plate 12. The first connecting column 6 extends from the bottom of the supporting block 4 into the slide groove 42, which can leave sufficient operating space for the electric tool to fasten and drive the first connecting column 6, facilitating quick assembly.

[0051] In order to prevent the first pressure code 5 from moving along the axial direction of the second connecting column 7 and affecting the fastening effect of the panel unit 3, in this embodiment, a positioning groove 43 is preferably provided on the top surface of the supporting block 4, and the extending direction of the positioning groove 43 is arranged to intersect with the axial direction of the second connecting column 7, and the connecting arm 52 extends into the positioning groove 43 to limit the axial movement of the first pressure code 5 along the second connecting column 7. In this embodiment, the extending direction of the positioning groove 43 is specifically perpendicular to the axial direction of the second connecting column 7, that is, parallel to the extending direction of the longitudinal drainage keel 1.

[0052] The support block 4 of this embodiment has a raised structure 44 that bulges downward at the position where the positioning groove 43 is set. One end of the raised structure 44 is connected to the rib 41, and the other end is in contact with the groove wall of the first water guide groove 11. The bending resistance of the support block 4 is enhanced, and tests have found that the vibration condition is significantly improved.

[0053] In order to strengthen the pressing effect of the first pressing code 5 on the panel unit 3, the end of the connecting arm 52 of this embodiment, that is, the part of the connecting arm 52 extending into the positioning groove 43, is provided with a bending portion 521 gradually approaching the pressing arm 51, and the end face of the bending portion 521 is preferably a cylindrical surface, and the positioning groove 43 is provided with a deflection groove 431 concavely arranged toward the convex rib 41, and the deflection groove 431 is a circular groove adapted to the end face of the bending portion 521, that is, a concave cylindrical surface. During the process of locking the connecting arm 52 by the second connecting column 7, the first pressing code 5 will adaptively deflect, specifically, the connecting arm 52 deflects in the direction close to the convex rib 41 with the end face axis of the bending portion 521 as the rotation axis. At this time, the pressing arm 51 will increase the pressure applied to the panel unit 3 to ensure that the pressing arm 51 is compacted on the fourth flanged edge 322 of the panel unit 3 to prevent the panel unit 3 from moving horizontally or vibrating up and down. The deflection groove 431 is a bending portion 521 of this embodiment, which includes a first surface arranged opposite to the convex rib 41, and a second surface arranged opposite to the convex rib 41, and the distance between the first surface and the second surface gradually decreases toward the end face of the bending portion 521, that is, the thickness of the bending portion 521 gradually decreases toward the end face. In addition, the bending portion 521 forms an angle of 20 to 70 degrees with the axial direction of the second connecting column 7, and the bending portion 521 extends in a direction away from the second connecting column 7, that is, the bending portion 521 is inclined. The bending portion 521 of this structure ensures that the first pressure code 5 is adaptively deflected during the process of the second connecting column 7 locking the connecting arm 52.

[0054] In addition, in order to ensure that the connecting arm 52 can also be flexibly flipped in the direction away from the rib 41 to facilitate the disassembly and assembly of the panel unit 3, the present embodiment preferably sets an inclined first groove wall 432 on the side opposite to the deflection groove 431 in the positioning groove 43. When the connecting arm 52 deflects in the direction away from the rib 41, the inclined first groove wall 432 can ensure that the longitudinal side frame 32 of the panel unit 3 is detached upward. This structure makes it unnecessary to completely detach the second connecting column 7 and the first pressing code 5 during the disassembly and assembly of the panel unit 3. It is only necessary to loosen the second connecting column 7 and flip the first pressing code 5 in the direction away from the rib 41 until the pressing arm 51 is offset from the fourth folded edge 322, and then the longitudinal side frame 32 of the panel unit 3 can be detached upward, which is particularly convenient for replacing a faulty photovoltaic panel unit during operation and maintenance.

[0055] When the second connecting column 7 (i.e., the bolt) is tightened, the torque will be converted into a downward pressing force of the first pressure code 5 on the longitudinal side frame 32, and the positioning grooves 43 on the left and right sides of the supporting block 4 are provided with a first groove wall 432 inclined on the side opposite to the deflection groove 431 to help unload the force and reduce the air bulging amount of the extruded section of the profile.

[0056] In addition, the top of the support block 4 of this embodiment is preferably provided with a positioning protrusion 45, and the longitudinal side frame 32 is arranged between the positioning protrusion 45 and the convex rib 41. The positioning protrusion 45 plays a limiting role when the panel unit 3 is installed, which can effectively reduce the cumulative error during installation. The support block 4 of this embodiment is a mirror-symmetrical element, and the support block 4 is mirror-symmetrical about the positioning protrusion 45, that is, the convex rib 41, the slide groove 42, the positioning groove 43, and the raised structure 44 on each support block 4 are symmetrically arranged in two, and each support block 4 fixes the longitudinal side frames 32 of the two panel units 3 respectively through two first pressure codes 5. Since the fixing points are separated on the left and right sides of the support block 4, the deformation of the support block 4 is smaller.

[0057] A first sealing structure is provided between two adjacent panel units 3 arranged in the longitudinal direction, the first sealing structure corresponds to the lateral side frame 31, and the first sealing structure is specifically a first waterproof rubber strip 8 abutting against the first folded edge 311. Fig.11 The first waterproof rubber strip 8 is a hollow tubular structure, and two chambers are arranged in parallel up and down. The first sealing structure is arranged in the center of the second water guide groove 21.

[0058] The transverse drainage keels 2 are arranged along the extension direction of the longitudinal drainage keel 1, and the adjacent second folded edges 312 of two adjacent panel units 3 are both extended into the second water guide groove 21, and the second folded edges 312 are in contact with the groove wall of the second water guide groove 21, and the two sides of the first waterproof rubber strip 8 are respectively in contact with the adjacent second folded edges 312 of the two adjacent panel units 3. The panel unit 3 of the transverse drainage keel 2 fixed on the longitudinal drainage keel 1 is positioned and pressed on the longitudinal drainage keel 1.

[0059] A second sealing structure is provided between two adjacent panel units 3 arranged in a transverse direction, the second sealing structure corresponds to the longitudinal side frame 32, and the second sealing structure is specifically a second waterproof rubber strip 9 abutting against two adjacent third folded edges 321. Fig.12 The second waterproof rubber strip 9 is a hollow tubular structure. The second sealing structure is arranged above the positioning protrusion 45.

[0060] In addition, to facilitate the overall fixed assembly of the photovoltaic waterproof bracket, the photovoltaic waterproof bracket of this embodiment also includes a supporting keel 101 and a second pressure code 102. The longitudinal drainage keel 1 is cross-arranged with the supporting keel and is fixed to the top of the supporting keel 101 through the second pressure code 102.

[0061] In summary, the implementation of the present invention has the following beneficial effects:

[0062] The mounting structure of the supporting block 4 and the first pressure code 5 of the present invention cooperate with the fixed panel unit 3 to eliminate the medium-pressure cover plate required by the original medium-pressure code 5, and reduce the water inflow of the longitudinal drainage keel 1. At the same time, it has strong bearing capacity, is not easy to bend or deform, and is not easy to vibrate and loosen, and can meet the requirements of a level 14 typhoon. It is also easy to position and install (bolts can be directly tightened with electric tools), and has lower cost than the solution of fixed installation using medium-pressure codes.

[0063] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
