Description

Technical Field

[0001] This utility model relates to the field of photovoltaic building technology, and more specifically, to a mounting bracket for photovoltaic modules and their bottom drainage channels. Background Technology

[0002] As a common type of roof for photovoltaic installation, sloping roofs currently employ multiple longitudinally spaced horizontal beams to address waterproofing issues. These beams are equipped with multiple transversely spaced drainage channels, on which photovoltaic modules are mounted. This system not only supports the photovoltaic modules but also drains rainwater, preventing water accumulation from damaging them.

[0003] Please refer to Figure 1 and Figure 2 The existing installation method for photovoltaic modules and their bottom drainage channel 1 is as follows: An upper pressure plate 3 and a lower pressure plate 5 are symmetrically located on the upper and lower sides of a crossbeam 4, with the upper pressure plate 3 pressing against the bottom side of the drainage channel 1. U-bolts 2 connect the upper and lower pressure plates 5 to achieve fixed installation of the drainage channel 1 and the crossbeam 4. Furthermore, a crossbeam 7 is installed at the opening of the drainage channel 1. The two sides of the crossbeam 7 are connected to the corresponding side walls of the drainage channel 1 with bolts 8. The crossbeam 7 is connected to a pressure block 6, and the photovoltaic modules are fixed to the pressure block 6 to achieve fixed installation of the photovoltaic modules and the drainage channel 1.

[0004] However, the above installation method has the following disadvantages: First, the upper and lower pressure plates and the crossbeam are separate structures, which need to be adjusted and installed one by one, which is cumbersome and has low installation efficiency; Second, due to the limited space inside the drainage channel, the space for bolt construction is small, the construction safety is high, and the installation efficiency is low.

[0005] In summary, how to solve the problems of cumbersome installation and low installation efficiency of existing photovoltaic modules and their bottom drainage channels is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a mounting bracket for photovoltaic modules and their bottom drainage channels, which enables convenient installation of photovoltaic modules and their bottom drainage channels.

[0007] Another objective of this invention is to provide a photovoltaic sloping roof that includes the aforementioned mounting bracket for photovoltaic modules and their bottom drainage channels.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A mounting bracket for a photovoltaic module and its bottom drainage channel includes a U-shaped plate and two mounting plates. The U-shaped plate is used to be upside down on the drainage channel, and the bottom plate of the U-shaped plate presses against both sides of the opening of the drainage channel. The two side plates of the U-shaped plate are inclined away from the bottom plate of the U-shaped plate, and the two side plates are integrally formed and connected to the two back-to-back mounting plates near the open ends of the U-shaped plate. Both mounting plates are provided with a first mounting hole for connecting a crossbeam by fasteners.

[0010] Preferably, the bottom plate of the U-shaped plate has two protrusions that are both stamped towards the open end of the U-shaped plate, and the two protrusions are respectively disposed adjacent to the two side plates of the U-shaped plate. The protrusions, the bottom plate of the U-shaped plate and the side plates of the U-shaped plate form a slot.

[0011] Preferably, the protrusion and the side plate of the U-shaped plate are parallel to each other.

[0012] Preferably, the cross-section of the protrusion is arc-shaped.

[0013] Preferably, the bottom plate of the U-shaped plate has a second mounting hole at the middle position for connecting the photovoltaic module via a connector.

[0014] Preferably, a limiting structure is integrally formed between the side plate at the open end of the U-shaped plate and the mounting plate, and the limiting structure is used to limit and engage the outer wall of the drainage groove.

[0015] Preferably, the limiting structure includes a protruding part and a snap-in part. The protruding part is connected to the mounting plate and bends towards the bottom plate of the U-shaped plate to connect to the snap-in part. The snap-in part is used to snap into the limiting groove at the bottom end of the outer wall of the drainage groove.

[0016] A photovoltaic sloping roof includes a beam, a drainage channel, photovoltaic modules, and a mounting bracket as described in any one of the preceding claims for the photovoltaic modules and their bottom drainage channels.

[0017] Preferably, the drainage channel has an M-shaped cross-section, and the bottom end of the outer wall of the drainage channel is integrally formed with a rolled edge plate. The side of the rolled edge plate away from the drainage channel is bent toward the opening of the drainage channel to form a limiting groove.

[0018] Preferably, the cross-section of the beam is U-shaped, and the closed end of the beam is provided with a third mounting hole. The fastener passes through the third mounting hole, the open end of the beam, and the first mounting hole in sequence and is fastened to the mounting plate.

[0019] This utility model provides a mounting bracket for photovoltaic modules and their bottom drainage channels, consisting of an integrally formed U-shaped plate and two mounting plates. During installation, the U-shaped plate is inverted and placed over the opening of the drainage channel. The two mounting plates on either side of the U-shaped plate are placed on a crossbeam and fixedly connected to the crossbeam using fasteners (e.g., bolts). At this point, the bottom plate of the U-shaped plate presses the drainage channel tightly against the crossbeam, thus securing the drainage channel and crossbeam. Subsequently, the bottom plate of the U-shaped plate is then fixedly connected to the photovoltaic module via connectors, thus achieving a secure installation of the photovoltaic module and the drainage channel.

[0020] In summary, compared to the existing separate structure of the upper and lower pressure plates and crossarm, the integrated mounting bracket of this application can fix the drainage channel and the crossarm while the U-shaped plate can be snapped onto the drainage channel, eliminating the need for secondary installation of the components for supporting the photovoltaic modules (i.e., the existing crossarm). This simplifies the operation, makes it more convenient and time-saving, and improves installation efficiency. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The core of this utility model is to provide a mounting bracket for photovoltaic modules and their bottom drainage channels, which enables convenient installation of photovoltaic modules and their bottom drainage channels.

[0035] Another core aspect of this invention is to provide a photovoltaic sloping roof that includes the aforementioned mounting bracket for photovoltaic modules and their bottom drainage channels.

[0036] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on this application. In addition, "first" and "second" are only used to describe effects and should not be construed as indicating or implying relative importance.

[0037] Please refer to Figures 3-6 This application provides a mounting bracket for photovoltaic modules and their bottom drainage channels, including a U-shaped plate 11 and two mounting plates 12. The U-shaped plate 11 is used to be upside down on the drainage channel 3, and the bottom plate of the U-shaped plate 11 presses against the two sides of the opening of the drainage channel 3. The two side plates of the U-shaped plate 11 are inclined away from the bottom plate of the U-shaped plate 11, and the two side plates are integrally formed and connected to the two back-facing mounting plates 12 adjacent to the opening ends of the U-shaped plate 11. Both mounting plates 12 are provided with first mounting holes 121 for connecting the crossbeam 2 through fasteners 4.

[0038] It should be noted that in the existing technology, the bottom of the drainage channel 3 is installed on the crossbeam 2, and the opening of the drainage channel 3 faces upward to ensure that rainwater can flow smoothly into the drainage channel 3 through the opening and avoid accumulation on the roof. Therefore, during installation, the U-shaped plate 11 is inverted on the drainage channel 3, and the bottom plate of the U-shaped plate 11 presses against both sides of the opening of the drainage channel 3, which can make the U-shaped plate 11 securely hold the drainage channel 3. In addition, both side plates of the U-shaped plate 11 are inclined away from the bottom plate of the U-shaped plate. That is to say, when the U-shaped plate 11 is inverted on the drainage channel 3, the side plates of the U-shaped plate 11 are V-shaped, which can ensure that there is a certain distance between the mounting plate 12 and the drainage channel 3, making it convenient to fasten the mounting plate 12.

[0039] In the above embodiment, during installation and use, the U-shaped plate 11 is inverted and placed on the opening of the drainage channel 3. Two mounting plates 12 on both sides of the U-shaped plate 11 are placed on the crossbeam 2 and fixedly connected to the mounting plates 12 and the crossbeam 2 using fasteners 4 (e.g., bolts). At this time, the bottom plate of the U-shaped plate 11 presses the drainage channel 3 tightly against the crossbeam 2, thus achieving a fixed installation of the drainage channel 3 and the crossbeam 2. Afterwards, the bottom plate of the U-shaped plate 11 is then fixedly connected to the photovoltaic module via connectors, thereby achieving a fixed installation of the photovoltaic module and the drainage channel 3.

[0040] As can be seen from the above description, compared with the existing separate structure of the upper and lower pressure plates and crossbeams, the integrated mounting bracket 1 of this application can fix the drainage channel 3 and the crossbeam 2, while the U-shaped plate 11 can be snapped onto the drainage channel 3. There is no need to install the components for supporting the photovoltaic modules (i.e. the existing crossbeams) again, which simplifies the operation, makes the operation convenient and time-saving, and improves the installation efficiency.

[0041] Based on the above embodiments, as a further preferred embodiment, the bottom plate of the U-shaped plate 11 is provided with two protrusions 111 that are both stamped toward the open end of the U-shaped plate 11, and the two protrusions 111 are respectively disposed adjacent to the two side plates of the U-shaped plate 11, and the protrusions 111, the bottom plate of the U-shaped plate 11 and the side plates of the U-shaped plate 11 form a slot.

[0042] Specifically, such as Figure 3 As shown, the bottom plate of the U-shaped plate 11 is pressed downward to form two protrusions 111. The two protrusions 111 are respectively adjacent to the two side plates of the U-shaped plate 11, and a preset distance is left between the protrusions 111 and the side plates in the lateral direction. This preset distance can be set according to the side wall thickness of the groove opening of the drainage channel 3. Thus, the protrusions 111, the bottom plate of the U-shaped plate 11, and the side plates of the U-shaped plate 11 can form a groove. In this way, during installation, the side wall of the groove opening of the drainage channel 3 can be inserted into the groove, which can restrict the movement of the drainage channel 3 and improve the stability of the installation of the drainage channel 3.

[0043] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 and Figure 6The protrusion 111 and the side plate of the U-shaped plate 11 are parallel to each other. In this way, during installation, the slot can be arranged along the arrangement direction (i.e., longitudinal direction) of the drainage groove 3, so that the side wall of the groove opening of the drainage groove 3 can be easily inserted into the slot, ensuring that the two are properly engaged.

[0044] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 The cross-section of the protrusion 111 is arc-shaped, which can not only increase the contact area between the protrusion 111 and the inner wall of the drainage channel 3 to effectively restrict the movement of the drainage channel 3, but also prevent the protrusion 111 from scratching the inner wall of the drainage channel 3.

[0045] Based on the above embodiments, as a further preferred option, please refer to... Figure 4 The bottom plate of the U-shaped plate 11 has a second mounting hole in the middle for connecting photovoltaic modules via connectors.

[0046] Understandably, the U-shaped plate 11, used to fix the photovoltaic modules, is inverted and rests on the drainage groove 3 with its bottom plate facing upwards. To achieve fixed installation of the photovoltaic modules, a second mounting hole is provided on the bottom plate of the U-shaped plate 11. This second mounting hole can be used to connect the pressure blocks on the photovoltaic modules via connectors (such as bolts) to achieve fixed installation of the photovoltaic modules. Furthermore, the second mounting hole is located in the middle of the bottom plate of the U-shaped plate 11, allowing the U-shaped plate 11 to better and more evenly distribute the pressure from the photovoltaic modules, ensuring uniform force distribution on the U-shaped plate 11 and preventing displacement of the U-shaped plate 11, thereby improving the stability of the photovoltaic module installation.

[0047] Based on the above embodiments, as a further preferred option, please refer to... Figure 6 A limiting structure 13 is integrally formed between the side plate at the open end of the U-shaped plate 11 and the mounting plate 12. The limiting structure 13 is used to engage with the outer wall of the drainage trough 3. In this way, the limiting structure 13 can further restrict the movement of the drainage trough 3, thereby further improving the stability of the installation of the drainage trough 3.

[0048] Preferably, there are two limiting structures 13, which are integrally connected to the two side plates of the opening end of the U-shaped plate 11 and the two mounting plates 12, thereby effectively restricting the movement of the drainage channel 3.

[0049] Considering the specific configuration of the limiting structure 13, in one particular embodiment, please refer to... Figure 6 The limiting structure 13 includes a protrusion 131 and a snap-in portion 132. The protrusion 131 is connected to the mounting plate 12 and bends towards the bottom plate of the U-shaped plate 11 to connect to the snap-in portion 132. The snap-in portion 132 is used to snap into the limiting groove 32 at the bottom end of the outer wall of the drainage groove 3.

[0050] Specifically, such as Figure 1As shown, the bottom end of the outer wall of the drainage trough 3 (the bottom end being the end furthest from the opening of the drainage trough 3) is provided with a limiting groove 32. The protruding part 131 connects to the mounting plate 12 and bends upward to connect to the snap-in part 132, which snaps into the limiting groove 32. With this structure, the limiting structure 13 can securely connect the mounting plate 12 while simultaneously snapping into and limiting the drainage trough 3. It should be noted that the shape of the snap-in part 132 is adapted to the limiting groove 32 to ensure a secure snap-in connection. The snap-in part 132 can be a downward protruding structure, or other structures can be used, as long as they can snap into and cooperate with the limiting groove 32.

[0051] To save processing costs and reduce processing difficulty, based on the above embodiments, as a further preferred embodiment, both sides of the U-shaped plate 11 are inclined plates, and the inclined plates pass over the rolled edge plate 31 at the bottom of the outer wall of the drainage groove 3 to connect to the mounting plate 12.

[0052] This utility model also provides a photovoltaic sloping roof, including a beam 2, a drainage channel 3, a photovoltaic module, and the mounting bracket for the photovoltaic module and its bottom drainage channel disclosed in the above embodiments.

[0053] It should be noted that the sloping roof has multiple horizontal beams 2 arranged longitudinally at intervals, and each horizontal beam 2 extends laterally. Multiple drainage channels 3 are arranged laterally at intervals, and each drainage channel 3 extends longitudinally on multiple horizontal beams 2. Each drainage channel 3 is fixed to multiple horizontal beams 2 by mounting brackets 1.

[0054] Based on the above embodiments, as a further preferred option, please refer to... Figure 6 The cross-section of the drainage trough 3 is M-shaped, and the bottom end of the outer wall of the drainage trough 3 is integrally formed with a rolled edge plate 31. The side of the rolled edge plate 31 away from the drainage trough 3 is bent toward the opening of the drainage trough 3 to form a limiting groove 32.

[0055] The drainage trough 3, with the aforementioned structure, has the following advantages: First, the M-shaped drainage trough 3 has an internal slope, which accelerates the flow of rainwater, thereby quickly draining the rainwater and effectively preventing water accumulation from damaging the photovoltaic modules. Second, the bottom of the side wall of the M-shaped drainage trough 3 is integrally connected to a rolled edge plate 31. This rolled edge plate 31 not only increases the contact area between the M-shaped drainage trough 3 and the crossbeam 2, which helps to improve the tightness of the connection between the drainage trough 3 and the crossbeam 2, but also can engage the limiting structure 13 on the mounting bracket 1, thereby improving the stability of the drainage trough 3 installation.

[0056] Based on the above embodiments, as a further preferred option, please refer to... Figure 6 The cross-section of the beam 2 is U-shaped, and the closed end of the beam 2 is provided with a third mounting hole. The fastener 4 passes through the third mounting hole, the open end of the beam 2 and the first mounting hole 121 in sequence and is fastened to the mounting plate 12.

[0057] The crossbeam 2 with the above structure has the following advantages: First, the U-shaped crossbeam 2 has high bending and shear strength, which can stably support the drainage trough 3 and the photovoltaic modules above it; Second, the U-shaped crossbeam 2 has an open end. During installation, the closed end of the crossbeam 2 faces down and the open end faces up, which makes it convenient for operators to fix the crossbeam 2 and the mounting plate 12. That is, the fastener 4 is inserted into the crossbeam 2 through the third mounting hole at the closed end of the crossbeam 2. The open end of the crossbeam 2 is relatively large, which makes it convenient for personnel to observe and fasten the fastener 4 through the first mounting hole 121 of the mounting hole to the mounting plate 12, which can improve the convenience of operation.

[0058] Preferably, fastener 4 can be a combination of hexagonal bolts with high load-bearing capacity and not easy to loosen. Of course, fastener 4 can also be other types of bolts, and is not the only one.

[0059] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0060] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0061] The above provides a detailed description of a photovoltaic module and its bottom drainage channel mounting bracket, as well as a photovoltaic sloping roof, provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
