Description

Fixing device for installing photovoltaic module on color steel tile

Technical Field

The embodiment of the disclosure relates to the technical field of photovoltaic industry, in particular to a fixing device for installing a photovoltaic module on a color steel tile.

Background

In order to respond to the call of energy conservation and emission reduction, more and more roofs of buildings are provided with photovoltaic assemblies for collecting solar energy to perform photovoltaic power generation. Currently, the roofs of many buildings use color steel tiles to carry the photovoltaic modules. The photovoltaic module can be fixed on the color steel tile through a fixing device. The three currently popular fastening devices are rail, fulcrum and glue, respectively.

The guide rail type fixing device is characterized in that guide rails are arranged in the direction perpendicular to the corrugated of the color steel tile, and then photovoltaic modules are mounted on the guide rails side by side. Such a fixing device requires a large amount of aluminum profile and is therefore costly. The installation process involves installing guide rails, color steel tile clamps, pressing blocks, bolts and the like, and has the advantages of multiple installation steps, multiple crossed working procedures, long construction period and high technical level requirement. And the fixing device has the advantages of more connecting pieces, high failure risk and difficult maintenance.

The fixing device of fulcrum type arranges a guide rail on the color steel tile clamp, the guide rail is parallel to the corrugated of the color steel tile, and the length of the guide rail is equal to the length of the color steel tile clamp. The fixing device of fulcrum type is complex in installation, and the point position of the color steel tile clamp is very accurate in placement. The untidy alignment of the color steel tile clamp can lead to the photovoltaic module not being installed. And such fastening devices are prone to connection failure. Because the supporting surface of the color steel tile clamp is limited, the photovoltaic module possibly slides out of the effective range of the color steel tile clamp due to vibration, thermal expansion, cold contraction and the like along with the time, so that the photovoltaic module is separated from the color steel tile clamp.

The adhesive fixing device is used for directly adhering the photovoltaic module to the color steel tile. The color steel tiles which can use the fixing device need to be customized, and are not suitable for adding a distributed photovoltaic system to an established factory building or a building. In the installation process, the gluing is greatly influenced by the outdoor environment. The reliability of the glue is affected by a plurality of factors, and the risk of connection failure of the glue is larger than that of the metal connecting piece. And such fixing devices are inconvenient for later operation and maintenance disassembly. When the photovoltaic module is disassembled, rubber tapping is needed, and the rubber tapping is not only laborious, but also the metal roof coating of the color steel tile is easy to damage.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. It will be apparent that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by those skilled in the art based on the described embodiments of the present disclosure without the need for creative efforts, are also within the scope of the protection of the present disclosure.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the presently disclosed subject matter belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

In this context, a direction in which the plurality of corrugations 110 are sequentially arranged is referred to as a first direction x. The direction in which each corrugation 110 extends is referred to as a third direction y (which may also be referred to as a running water direction). The direction perpendicular to the plane of the color steel tile is referred to as the second direction z. The first direction x, the third direction y and the second direction z are perpendicular to each other. The photovoltaic modules 200 are sequentially arranged in the third direction y. One or more securing devices 300 may be provided between two adjacent photovoltaic modules 200 and at the photovoltaic modules 200 located at the head-to-tail end. The fixing device 300 is used for mounting the photovoltaic module 200 on the color steel tile 100. Fig. 2 shows a partial enlarged view of fig. 1. The relative positions of the fixture 300 and the photovoltaic module 200 according to embodiments of the present disclosure can be clearly seen in fig. 2.

Fig. 3 illustrates a first structural schematic of a fixing device 300 according to an embodiment of the present disclosure. The fixing device 300 may include: the jig, the pressing block 330a, the first connector 43, the second connector 44, and the third connector 41. Wherein the clamp may include a first clamp 310a and a second clamp 320a. The first clamping member 310a and the second clamping member 320a are clamped to each other in the first direction x by the first connecting member 43.

The press block 330a has at least one protrusion (333 and/or 337) with respect to the first and second holders 310a and 320a in the third direction y.

In the example of fig. 3, the first, second and third connection members 43, 44 and 41 may be bolts, which may be fixed by nuts. Because of the angular relationship, only the nut 42 that mates with the third connector 41 is shown in fig. 3.

The fixing device 300 shown in fig. 3 may be composed of a jig shown in fig. 7 or 8 and a pressing block shown in fig. 13. A schematic structure of the clamp in the fixing device 300 shown in fig. 3 in a separated state will be described with reference to fig. 7. The first clamping member 310 may include: the first leg 311, the first support portion 312, the first platform portion 313, the second support portion 317, the first stopper 315, the first through hole 314, and the second through hole 316. The first supporting portion 312 may contact the color steel tile to support the first clamping member 310a. In the second direction z, the first support 312 is located above the first leg 311 and is used to support the first platform 313. In one example, the first platform portion 313 may be parallel to the first leg 311. The first through hole 314 is located on the first surface of the first land portion 313. In one example, the first through hole 314 may be located at a central position of the first land portion 313. The second connector is able to pass through the first through hole 314 in the second direction z. The second support 317 is located above the first platform 313. The second supporting portion 317 may be located at a side of the first platform portion 313 adjacent to the second clamping member 320 a. The second through hole 316 and the first stopper 315 are located on the second surface of the second supporting portion 317. In one example, the second through hole 316 may be located at a center position of the second supporting portion 317, and the first stopper 315 may be located at an upper end of the second supporting portion 317.

In some embodiments of the present disclosure, the first leg 311, the first support 312, the first platform 313, the second support 317, and the first stopper 315 may be integrally formed.

The second clamping member 320a may include: a second leg 321, a third support portion 322, a second platform portion 323, a second stopper 325, a third through hole 324, and a fourth through hole 326. The third supporting portion 322 may contact the color steel tile to support the second clamping member 320a. In the second direction z, the third support portion 322 is located above the second leg 321 and serves to support the second platform portion 323, and the second platform portion 323 may be located at a middle region of the third support portion 322. The third through hole 324 is located on the third surface of the second land portion 323. The third connector is capable of passing through the third through hole 324 in the second direction z. In one example, the third through hole 324 may be located at a center position of the second land portion 323. The fourth through hole 326 and the second stopper 325 are located on the fourth surface of the third supporting portion 322. The second surface of the second support 317 is disposed opposite the fourth surface of the third support 322.

In some embodiments of the present disclosure, the second leg 321, the third support portion 322, the second platform portion 323, and the second stopper 325 may be integrally formed.

In some embodiments of the present disclosure, the first support 312 and the third support 322 can be shaped to conform to the corrugations of the color steel tile. Fig. 11 and 12 show structural schematic diagrams of the jig in the fixing device according to the embodiment of the present disclosure according to a modification of the corrugated shape of the color steel tile, in addition to the shape shown in fig. 7. Those skilled in the art will appreciate that the shape of the first support 312 and the third support 322 may also have other variations to accommodate other shaped corrugations. Embodiments of the present disclosure do not limit the shape of the first support 312 and the third support 322.

In some embodiments of the present disclosure, the number of second through holes 316 and fourth through holes 326 is equal, and may be one or more. In the example of fig. 7, 2 second through holes 316 and 2 fourth through holes 326 are shown. The number of the first through holes 314 and the third through holes 324 may be different or the same, and may be one or a plurality. In the example of fig. 7, 1 first through hole 314 and 1 third through hole 324 are shown.

Fig. 8 is a schematic view showing a structure of the clamp in the fixing device shown in fig. 3 in a locked state. The first stopper 315 and the second stopper 325 are locked with each other to restrict the relative positions of the first clamping member 310a and the second clamping member 320a, so that the second through hole 316 is aligned with the fourth through hole 326. The first connector is capable of passing through both the second through hole 316 and the fourth through hole 326 in the first direction x. With the clamp locked, a gap is left between the first support portion 312 and the third support portion 322, and the size of the gap is set according to the corrugated thickness of the color steel tile.

Fig. 13 is a schematic view showing a structure of the pressing block 330a in the fixing device shown in fig. 3. The press block 330a may include: the first bridging portion 336a, the second bridging portion 336b, the fourth supporting portion 335, the fifth supporting portion 334, the first protruding portion 337, and the second protruding portion 333. The first and second bridging portions 336a and 336b bridge the fourth and fifth supporting portions 335 and 334. The first bridging portion 336a and the second bridging portion 336b are located at both sides of the fourth supporting portion in the first direction x. The distance between the first bridging portion 336a and the second bridging portion 336b is greater than the sum of the thicknesses of the second supporting portion 317 of the first clamping member 310a and the third supporting portion 322 of the second clamping member 320 a. In this way, the second support portion 317 and the third support portion 322 can jointly pass through the gap between the first bridge portion 336a and the second bridge portion 336b in the locked state. The first bridge portion 336a is provided with a fifth through hole 332a. The second bridge portion 336b is provided with a sixth through hole 332b. The second connector is able to pass through both the first through hole 314 and the fifth through hole 332a in the second direction z. The third connection member passes through both the third through hole 324 and the sixth through hole 332b in the second direction z. The first protruding portion 337 and the first bridging portion 336a are located at both sides of the fourth supporting portion 335 in the second direction z. The second protruding portion 333 and the first bridging portion 336a are located at both sides of the fifth supporting portion 334 in the second direction z. Similarly, the first protruding portion 337 and the second bridging portion 336b are located on both sides of the fourth supporting portion 335 in the second direction z. The second protruding portion 333 and the second bridging portion 336b are located at both sides of the fifth supporting portion 334 in the second direction z.

In some embodiments of the present disclosure, the first bridge portion 336a and the second bridge portion 336b may be aligned in the second direction z. The number of the fifth through holes 332a and the sixth through holes 332b may be different or the same, and may be one or a plurality. In the example of fig. 13, 1 fifth through hole 332a and 1 sixth through hole 332b are shown.

In this context, the surfaces of the fourth support portion 335 and the fifth support portion 334 facing each other are referred to as inner walls, and the surfaces of the fourth support portion 335 and the fifth support portion 334 facing away from each other are referred to as outer walls.

In some embodiments of the present disclosure, the length of the second support 317 and the third support 322 in the third direction y may be less than the distance between the inner wall of the fourth support 335 and the inner wall of the fifth support 334. Since the first and second holders 310a and 320a are first installed when the fixing device 300 is installed, a gap needs to be reserved between the first and second holders 310a and 320a and the photovoltaic module 200 to accommodate the fourth and fifth supporting parts 335 and 334, otherwise the pressing block 330a cannot be installed on the jig.

For ease of installation, embodiments of the present disclosure provide a securing device 300 as shown in fig. 4. The fixing device 300 shown in fig. 4 may be composed of a jig shown in fig. 7 or 8 and a pressing block shown in fig. 14. The fourth support portion 335 and the fifth support portion 334 are provided with a first notch 331, respectively, as can be seen more clearly with reference to fig. 14. In this way, the lengths of the second and third supporting parts 317 and 322 in the third direction y may be set to be equal to or greater than the distance between the outer wall of the fourth supporting part 335 and the outer wall of the fifth supporting part 334. The second supporting portion 317 and the third supporting portion 322 can pass through the first notch 331. Therefore, there is no need to reserve a space between the first and second clamps 310a and 320a and the photovoltaic module 200 when the first and second clamps 310a and 320a are installed, and the operation is simpler. In addition, the lengths of the second supporting portion 317 and the third supporting portion 322 in the third direction y should be smaller than the farthest distance between the first protruding portion 337 and the second protruding portion 333, so that the first protruding portion 337 and the second protruding portion 333 can press the photovoltaic modules on both sides.

For ease of installation, embodiments of the present disclosure also provide for a securing device 300 as shown in fig. 5. The fixing device 300 shown in fig. 4 may be composed of a clamp (including a first clamp 310b and a second clamp 320 b) shown in fig. 9 and a pressing block 330a shown in fig. 13. The second notch q2 is provided in each of the second support 317 and the third support 322 as more clearly seen with reference to fig. 9. The second notch q2 is located at the upper left and right corners of the second support portion 317 and at the upper left and right corners of the third support portion 322 on a plane formed by the second direction z and the third direction y. So that the lengths of the second and third supporting parts 317 and 322 in the third direction y may be set to be equal to or greater than the distance between the outer wall of the fourth supporting part 335 and the outer wall of the fifth supporting part 334. At the time of mounting the press block, the fourth support portion 335 and the fifth support portion 335 are arranged on the second notch q2 in the second direction z. Therefore, there is no need to reserve a space between the first and second clamps 310a and 320a and the photovoltaic module 200 when the first and second clamps 310a and 320a are installed, and the operation is simpler. In addition, the lengths of the second supporting portion 317 and the third supporting portion 322 in the third direction y should be smaller than the farthest distance between the first protruding portion 337 and the second protruding portion 333, so that the first protruding portion 337 and the second protruding portion 333 can press the photovoltaic modules on both sides.

As described above, the second and third connection members 44 and 41 may be bolts, which may be fixed by nuts. In some embodiments of the present disclosure, the second connector 44 and the third connector 41 may be secured by a T-nut. Fig. 6 shows a schematic configuration of a fixing device 300 applied to a T-nut. The fixing device 300 shown in fig. 6 may be composed of a clamp (including a first clamp 310c and a second clamp 320 c) shown in fig. 10 and a pressing block 330a shown in fig. 13. The first clamping member 310c in fig. 6 differs from the first clamping member 310a in fig. 3 in that: in the second direction z, a groove 311c capable of accommodating a T-nut is provided at the lower surface of the first land portion 313. The second clamping member 320c in fig. 6 is different from the first clamping member 320a in fig. 3 in that: in the second direction z, a groove 321c capable of accommodating a T-nut is provided at the lower surface of the second stage portion 323.
