Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic power generation, in particular to a photovoltaic waterproof bracket. Background Art

[0002] As the roof of a building, a photovoltaic panel can not only make full use of sunlight for power generation, but also help reduce the indoor temperature of the building. Using a photovoltaic panel as the roof of a building requires the photovoltaic panel to have good waterproof performance. With the rapid development of the photovoltaic industry, enterprises in the industry are all pursuing the development of photovoltaic products with low cost and high reliability.

[0003] The existing V-shaped waterproof bracket for photovoltaic panels adopts a structure in which a V-groove supporting block and a traditional middle / edge first press code are used to fixedly install a longitudinal drainage keel, a panel unit and a supporting keel. On the one hand, using a middle press code to fix the panel unit will result in a large 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 blocking cover plate above the middle press code to reduce the water flow into the V-shaped waterproof bracket, which increases the cost, and the water blocking cover plate is difficult to be fixedly secured and is easily blown away, further affecting the waterproof effect of the product; on the other hand, when using a middle press code to fix the panel unit, at each node, two panel units are pressed tightly by a single middle press code and a supporting block being locked. The supporting block is prone to bending deformation and thus vibration, there is a risk of loosening of the first press code bolt and failure of the panel unit fixation.

[0004] Therefore, it is necessary to improve the existing V-shaped waterproof bracket to further enhance the waterproof reliability and connection reliability of the product without increasing the cost. Summary of the Utility Model

A buckling groove is formed between the pressing arm and the connecting arm. The convex rib extends into the buckling groove. The connecting arm is connected to the convex rib, and the pressing arm abuts against the vertically arranged side frame.

[0011] As an improvement of the above solution, the supporting block is provided with a positioning groove. The extending direction of the positioning groove is arranged crosswise with respect to the axial direction of the second connecting column. The connecting arm extends into the positioning groove to limit the movement of the first pressing code along the axial direction of the second connecting column.

[0012] As an improvement of the above solution, the end of the connecting arm is provided with a bending part which gradually approaches the pressing arm. The end face of the bending part is a cylindrical surface. The positioning groove is provided with a deflection groove which is recessed towards the convex rib. The deflection groove is adapted to the end face of the bending part. During the process of the second connecting column locking the connecting arm, the connecting arm deflects towards the direction close to the convex rib with the axis of the end face of the bending part as the rotation axis.

[0013] As an improvement of the above solution, the bending part includes a first surface which is oppositely arranged with respect to the convex rib and a second surface which is arranged facing away from the convex rib. The distance between the first surface and the second surface gradually decreases towards the direction close to the end face of the bending part.

[0014] As an improvement of the above solution, support plates are arranged on both sides of the first water guide groove. The horizontal drainage keel is arranged on the support plates of two adjacent vertically arranged drainage keels.

[0015] The supporting block is provided with a sliding groove which is adapted to the support plate. The first connecting column extends into the sliding groove from the bottom of the supporting block and abuts against the support plate.

[0016] As an improvement of the above solution, a positioning protrusion is arranged on the top of the supporting block. The vertically arranged side frame is arranged between the positioning protrusion and the convex rib.

[0017] As an improvement of the above solution, a first sealing structure is arranged between two adjacent panel units which are arranged longitudinally. The first sealing structure is arranged at the center of the second water guide groove.

[0018] A second sealing structure is provided between two adjacent panel units arranged horizontally, and the second sealing structure is provided above the positioning protrusion.

[0019] As an improvement to the above solution, the panel unit is provided with an assembly cavity with an open bottom.

[0020] The longitudinal side frame includes a third folding edge and a fourth folding edge connected to the third folding edge. The third folding edge is arranged parallel to the rib. The fourth folding edge is arranged at the bottom of the panel unit and is located on the side of the third folding edge close to the assembly cavity. The fourth folding edge is arranged on the top surface of the supporting block. The first pressing code extends into the assembly cavity and abuts against the top surface of the fourth folding edge.

[0021] As an improvement to the above solution, it further includes a support keel and a second pressing code. The longitudinal drainage keel and the support keel are arranged crosswise and are fixed to the top of the support keel through the second pressing code.

[0022] Implementing the present utility model has the following beneficial effects:

[0023] The present utility model discloses a photovoltaic waterproof bracket. By providing a supporting block straddling the first water guide groove on the longitudinal drainage keel, the supporting block and the longitudinal drainage keel are fixedly connected through a first connecting column. The transverse drainage keel is arranged on the supporting plates of two adjacent longitudinal drainage keels. The second water guide groove of the transverse drainage keel communicates with the first water guide groove. The horizontal side frame of the panel unit extends into the second water guide groove. The longitudinal side frame of the panel unit is arranged on the top of the supporting block. The first pressing code and the rib on the top of the supporting block are fixed through a second connecting column whose axial direction is parallel to the extending direction of the transverse drainage keel, so that the first pressing code and the top of the longitudinal side frame are used to fix the panel unit and the longitudinal drainage keel, and at the same time, the transverse drainage keel is positioned and assembled on the positioned longitudinal drainage keel. Since the structure for fixing the panel unit hardly occupies the plane laying space of the panel unit, the panel unit can almost completely cover the longitudinal drainage keel and the transverse drainage keel, reducing the water flow into the longitudinal drainage keel and the transverse drainage keel. There is no need to additionally provide a water blocking cover plate to reduce the water flow into the longitudinal drainage keel and the transverse drainage keel, reducing the cost. At the same time, the risk of the drainage cover plate being blown off is avoided, and the reliability of the waterproof structure is higher.

[0024] In addition, the panel unit is fixed on the supporting block by the pressure of the first pressing code. The second connecting column connecting and fixing the supporting block and the first pressing code has an axial direction parallel to the extending direction of the transverse drainage keel. Under extreme weather conditions, on the one hand, when the panel unit drives the first pressing code and the supporting block to vibrate up and down, the second connecting column is not easily loosened due to vibration, reducing the risk of the panel unit becoming unfixed. On the other hand, the second connecting column is mainly subjected to the upward shear force transmitted from the first pressing code and the supporting block. Compared with the axial tensile force mainly borne by the middle pressing bolt in the existing form of fixing the panel unit with the pressing code, the shear bearing capacity of the second connecting column is stronger than the tensile bearing capacity. Therefore, the reliability of the photovoltaic waterproof bracket installation structure is stronger in extreme cases. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0038] As Figures 1 to 12 shown, an embodiment of a photovoltaic waterproof bracket is provided in this embodiment, which includes a longitudinal drainage keel 1, a transverse drainage keel 2, a panel unit 3 and a locking assembly. A first water guide groove 11 is formed at the top of the longitudinal drainage keel 1, and support plates 12 are arranged on both sides of the first water guide groove 11. The transverse drainage keel 2 is placed on the support plates 12 of two adjacent longitudinal drainage keels 1, and a second water guide groove 21 is formed at the top of the transverse drainage keel 2, and the second water guide groove 21 communicates with the first water guide groove 11. The locking assembly includes a supporting block 4, a first pressing code 5, a first connecting column 6 and a second connecting column 7. The supporting blocks 4 are arranged along the extending direction of the longitudinal drainage keel 1. The supporting block 4 straddles the first water guide groove 11 and is fixedly connected to the longitudinal drainage keel 1 through the first connecting column 6. At least two ribs 41 are arranged at the top of the supporting block 4. The panel unit 3 is provided with adjacent transverse side frames 31 and longitudinal side frames 32. The transverse side frame 31 extends into the second water guide groove 21, and the longitudinal side frame 32 is arranged on the top of the supporting block 4. The first pressing code 5 is connected to the rib 41 through the second connecting column 7 and abuts against the longitudinal side frame 32. The axial direction of the second connecting column 7 is parallel to the extending direction of the transverse drainage keel 2.

[0039] In this embodiment, by providing a supporting block 4 straddling the first water guide groove 11 on the longitudinal drainage keel 1, the supporting block 4 is fixedly connected to the longitudinal drainage keel 1 through a first connecting column 6. The transverse drainage keel 2 is arranged on the supporting plates 12 of two adjacent longitudinal drainage keels 1. The second water guide groove 21 of the transverse drainage keel 2 communicates with the first water guide groove 11. 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. The first pressing code 5 is fixed to the rib 41 on the top of the supporting block 4 through a second connecting column 7 whose axis is parallel to the extending direction of the transverse drainage keel 2, so that the first pressing code 5 is in contact with the top of the longitudinal side frame 32, realizing the fixation of the panel unit 3 and the longitudinal drainage keel 1, and at the same time realizing the positioning and assembly of the transverse drainage keel 2 on the positioned longitudinal drainage keel 1. Since the structure for fixing the 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 water flow into the longitudinal drainage keel 1 and the transverse drainage keel 2. There is no need to separately set a water retaining cover plate to reduce the water flow into the longitudinal drainage keel 1 and the transverse drainage keel 2, reducing the cost, and at the same time avoiding the risk of the drainage cover plate 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 pressing code 5. The second connecting column 7 connecting the supporting block 4 and the first pressing code 5 has an axis parallel to the extending direction of the transverse drainage keel 2. Under extreme weather conditions, on the one hand, when the panel unit 3 drives the first pressing code 5 and the supporting block 4 to vibrate up and down, the second connecting column 7 is not easily loosened by vibration, reducing the risk of the fixation failure of the panel unit 3. On the other hand, the second connecting column 7 is mainly subjected to the upward shear force transmitted from the first pressing code 5 and the supporting block 4. Compared with the existing form in which the pressing bolt for fixing the panel unit 5 is mainly subjected to axial tensile force, the shear bearing capacity of the second connecting column 7 is stronger than the tensile bearing capacity. Therefore, the reliability of the photovoltaic waterproof support installation structure is stronger in extreme cases.

[0040] The first connecting column 6 and the second connecting column 7 of this embodiment are both preferably bolts, and the supporting block 4 and the first pressing code 5 are both preferably formed by aluminum alloy extrusion.

[0041] To facilitate comparing the gap between the shear bearing capacity and the tensile bearing capacity of the second connecting column 7, taking an M8 bolt as an example, the shear bearing capacity of the bolt is 1.3 times the tensile bearing capacity.

[0042] Each panel unit 3 of this embodiment is pressed tightly through the shear force between the second connecting column 7, the first pressing code 5 and the rib 41, further enhancing the waterproof property and connection reliability of the product without increasing the cost.

[0043] Specifically, in combination with Figure 3, the panel unit 3 of this embodiment is provided with an assembly cavity with an open bottom, 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 folding edge 311 and a second folding edge 312 connected to the first folding edge 311. The first folding edge 311 is arranged parallel to the side wall of the second water guide groove 21. The second folding edge 312 is arranged at the bottom of the panel unit 3 and is located on the side of the first folding edge 311 close to the assembly cavity. The second folding edge 312 is arranged at the bottom of the second water guide groove 21. The second folding edge 312 is preferably formed by folding the first folding edge 311 into the assembly cavity.

[0044] Combined with Figure 6 and Figure 7 , the longitudinal side frame 32 includes a third folding edge 321 and a fourth folding edge 322 connected to the third folding edge 321. The third folding edge 321 is arranged parallel to the rib 41. The fourth folding edge 322 is arranged at the bottom of the panel unit 3 and is located on the side of the third folding edge 321 close to the assembly cavity. The fourth folding 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 folding edge 322. The fourth folding edge 322 is preferably formed by folding the third folding edge 321 into the assembly cavity.

[0045] 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.

[0046] Combined with Figure 10 , the first pressing code 5 of this embodiment specifically includes a pressing arm 51 and a connecting arm 52 arranged oppositely. A clamping groove 53 is formed between the pressing arm 51 and the connecting arm 52. The rib 41 extends into the clamping groove 53. The connecting arm 52 is connected to the rib 41 through a second connecting column 7, and the pressing arm 51 abuts against the longitudinal side frame 32, specifically against the top surface of the fourth folding edge 322. The cross-sectional area of the end of the pressing arm 51 gradually increases to increase the acting area pressing on the longitudinal side frame 32.

[0047] Combined with Figures 6 to 9 , to facilitate the arrangement and installation of the supporting block 4 along the extension direction of the longitudinal drainage keel 1 and at the same time strengthen the firmness of the connection between the supporting block 4 and the longitudinal drainage keel 1 in the vertical direction, the structure of the supporting block 4 of this embodiment is provided with a sliding groove 42 adapted to the support plate 12.

[0048] The supporting block 4 of this embodiment straddles the first water guide groove 11 and is fixedly connected to the support plate 12 of the longitudinal drainage keel 1 through the first connecting column 6.

[0049] Specifically, the first connecting column 6 extends into the sliding groove 42 from the bottom of the supporting block 4 and abuts against the supporting plate 12. The first connecting column 6 extending into the sliding groove 42 from the bottom of the supporting block 4 can leave sufficient operating space for the electric tool to tightly drive the first connecting column 6, facilitating quick assembly.

[0050] To prevent the first pressing code 5 from moving axially along 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. The extending direction of the positioning groove 43 is arranged to intersect with the axial direction of the second connecting column 7. The connecting arm 52 extends into the positioning groove 43 to limit the axial movement of the first pressing code 5 along the second connecting column 7. Specifically, the extending direction of the positioning groove 43 in this embodiment is vertically crossed with the axial direction of the second connecting column 7, that is, parallel to the extending direction of the longitudinal drainage keel 1.

[0051] In this embodiment, the supporting block 4 has a raised structure 44 that bulges downward at the position where the positioning groove 43 is provided. One end of the raised structure 44 is connected to the rib 41, and the other end is attached to the groove wall of the first water guide groove 11. The bending resistance of the supporting block 4 is strengthened, and it is found through testing that the vibration situation is significantly improved.

[0052] To strengthen the pressing effect of the first pressing code 5 on the panel unit 3, at the end of the connecting arm 52 in this embodiment, that is, the part where the connecting arm 52 extends into the positioning groove 43, there is a bending part 521 that gradually approaches the pressing arm 51. The end face of the bending part 521 is preferably a cylindrical surface. The positioning groove 43 is provided with a deflection groove 431 that is concave toward the rib 41. The deflection groove 431 is a circular groove that is adapted to the end face of the bending part 521, that is, an inwardly concave cylindrical surface. During the process of the second connecting column 7 locking the connecting arm 52, the first pressing code 5 will deflect adaptively. Specifically, the connecting arm 52 deflects toward the direction close to the rib 41 with the axis of the end face of the bending part 521 as the rotation axis. At this time, the pressing arm 51 will increase the pressure applied to the panel unit 3, ensuring that the pressing arm 51 presses firmly on the fourth folding edge 322 of the panel unit 3 and preventing the panel unit 3 from translating or vibrating up and down. The deflection groove 431 of this embodiment. The bending part 521 includes a first surface opposite to the rib 41 and a second surface facing away from the rib 41. The distance between the first surface and the second surface gradually decreases in the direction close to the end face of the bending part 521, that is, the thickness of the bending part 521 gradually decreases in the direction close to the end face. In addition, the bending part 521 forms an angle of 20 - 70° with the axial direction of the second connecting column 7, and the bending part 521 extends in the direction away from the second connecting column 7, that is, the bending part 521 is inclined. The bending part 521 with this structure ensures that the first pressing code 5 deflects adaptively during the process of the second connecting column 7 locking the connecting arm 52.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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. Figure 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.

[0057] The transverse drainage keels 2 are arranged along the extending direction of the longitudinal drainage keel 1. The adjacent second folding edges 312 of two adjacent panel units 3 extend into the second water guide groove 21, and the second folding edges 312 are in contact with the groove walls of the second water guide groove 21. Both sides of the first waterproof rubber strip 8 are in contact with the adjacent second folding edges 312 of two adjacent panel units 3. The panel unit 3 where the transverse drainage keel 2 is fixed on the longitudinal drainage keel 1 is positioned and pressed tightly on the longitudinal drainage keel 1.

[0058] A second sealing structure is provided between two adjacent panel units 3 arranged horizontally, and the second sealing structure corresponds to the longitudinal side frame 32. The second sealing structure is specifically a second waterproof rubber strip 9 that is in contact with two adjacent third folding edges 321. As Figure 12 , the second waterproof rubber strip 9 is in a hollow tubular structure. The second sealing structure is arranged above the positioning protrusion 45.

[0059] In addition, for the convenience of the overall fixed assembly of the photovoltaic waterproof bracket, the photovoltaic waterproof bracket of this embodiment further includes a support keel 101 and a second pressing code 102. The longitudinal drainage keel 1 is arranged crosswise with the support keel and is fixed on the top of the support keel 101 through the second pressing code 102.

[0060] In summary, implementing the present utility model has the following beneficial effects:

[0061] The installation structure of the supporting block 4 and the first pressing code 5 of the present utility model for fixing the panel unit 3 cancels the middle pressing cover plate required in the original middle pressing code 5 form, reduces the water inflow of the longitudinal drainage keel 1, has strong bearing capacity, is not easy to bend and deform, is not easy to vibrate and loosen, can meet the requirements of a level 14 typhoon, and the positioning and installation are simple (bolts can be tightened directly with power tools), and the cost is lower compared with the scheme of fixing and installing with a middle pressing code.

[0062] The above-disclosed is only a preferred embodiment of the present utility model, and of course, it cannot be used to limit the scope of rights of the present utility model. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
