Description

Technical Field

[0001] This utility model relates to the field of photovoltaic roof installation technology, specifically to a waterproof structure for photovoltaic roofs that uses concealed fasteners and clamps for connection. Background Technology

[0002] Photovoltaic roofs are a technology that combines solar photovoltaic power generation systems with the roof structure of buildings. These roofs not only have the functions of traditional roofs, such as waterproofing, heat insulation, and heat insulation, but also convert sunlight into electricity through photovoltaic modules, realizing the utilization of clean energy. As an important part of distributed application scenarios, photovoltaic roofs are gradually becoming a new favorite in the construction field.

[0003] Among existing photovoltaic roofing technologies, BIPV (Building Integrated Photovoltaics) technology is particularly noteworthy. BIPV technology achieves a perfect integration of photovoltaics and buildings by incorporating photovoltaic modules as part of the building materials. These photovoltaic modules not only have the function of generating electricity, but also undertake building functions such as exterior decoration, heat preservation, and waterproofing. However, waterproofing has always been a key technical challenge that needs to be addressed during the installation of BIPV systems.

[0004] Existing BIPV systems often use self-tapping screws to drill through holes in the longitudinal water channels to fix them to the roof purlins. While this fixing method is simple and quick, it has a significant drawback: water can easily flow into the roof purlins through the gaps between the through holes and the self-tapping screws, causing roof leaks. Once the roof leaks, it will not only affect the normal operation of the photovoltaic system and reduce power generation efficiency, but may also damage the overall structure of the building.

[0005] Chinese patent document CN106522479A discloses a BIPV waterproof photovoltaic roof installation system, including solar panels and longitudinal water channels mounted on roof purlins. The solar panels are mounted above two adjacent longitudinal water channels. Each longitudinal water channel has a water collection cavity and a receiving cavity. The receiving cavity is open at the bottom and closed at the top. The longitudinal water channels are connected to the roof purlins via connectors, with a portion of the connectors located inside the receiving cavity. However, the following defects still exist in the implementation process:

[0006] Although the device described in the aforementioned literature has an opening at the bottom and a closed top in the longitudinal water tank cavity, and there are no through holes, which can effectively prevent water seepage and solve the problem of roof leakage, the size of the zigzag galvanized folding piece in the aforementioned device is fixed and cannot be applied to roof purlins of different heights. Utility Model Content

[0007] The purpose of this invention is to provide a waterproof structure for photovoltaic roofs that uses concealed fasteners and clamps for connection, so as to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A photovoltaic roof waterproofing structure using concealed fasteners and clamps includes purlins, mounting tray assemblies, M-shaped water channels, and pressure plate assemblies. The upper end of the purlin contacts the lower end of the M-shaped water channel. The pressure plate assembly is located in the inner cavity of the M-shaped water channel. The mounting tray assembly includes a first connecting block, a second connecting block symmetrically slidably connected to the upper part of the first connecting block, and a third connecting block fixedly connected to the opposite side of each of the two second connecting blocks. A first slider is fixedly connected to the lower end of the second connecting block, and the first slider is slidably connected to the upper part of the first connecting block. A first threaded rod is symmetrically rotatably connected to the opposite side of the upper part of the first connecting block, and the first threaded rod on the same side is threadedly connected to the first slider. The purlin is located in the inner cavity of the first connecting block, and the M-shaped water channel is fixedly connected to the second connecting block by self-tapping screws.

[0010] Using the above technical solution, by rotating the threaded rod, the slider can be raised and lowered above the connecting block, thereby raising and lowering the connecting block. The upper end of the connecting block is then in contact with the lower end of the M-shaped water guide groove. The M-shaped water guide groove is then fixedly connected to the connecting block by self-tapping screws, thereby fixing the position of the M-shaped water guide groove and allowing the connecting block to be used for purlins of different heights.

[0011] A further improvement of the present invention is that a handle is fixedly connected to the side of the threaded rod away from the connecting block 2, and a number of anti-slip grooves are arranged in a ring array on the outer surface of the handle.

[0012] In the above technical solution, several anti-slip grooves are arranged in a ring array on the outer surface of the handle, thereby enhancing the friction between the handle and the operator's hand, which facilitates the operation of the handle rotation.

[0013] A further improvement of the present invention is that the pressure plate assembly includes a base, the base is fixedly connected to the connecting block three by bolts, buffer pads are symmetrically fixedly connected to the upper part of the base, the upper ends of the two buffer pads are fixedly connected to a pressing edge assembly, and a threaded rod three is threadedly connected to the middle of the pressing edge assembly, and the threaded rod three is rotatably connected to the base.

[0014] In the above technical solution, the base and connecting block three are fixedly connected by bolts, thereby fixing the position of the base in the inner cavity of the M-shaped water guide channel. The threaded rod three is rotatably connected to the base, and then the threaded rod three is threadedly connected to the pressing edge assembly. Thus, by rotating the threaded rod three, the pressing edge assembly can be driven to rise and fall, and then the pressing edge assembly can fix photovoltaic panels of different sizes on the M-shaped water guide channel.

[0015] A further improvement of the present invention is that the pressing component includes a pressing block, a plurality of sliding grooves are symmetrically opened on the upper part of the pressing block, and a slider two is slidably connected to the inner cavity of each sliding groove. The lower ends of two slider two on the same side are fixedly connected to a backing plate. A threaded rod two is symmetrically threadedly connected to the middle part of the pressing block, and the threaded rod two on the same side is rotatably connected to the backing plate.

[0016] The above technical solution involves threading the threaded rod two to the pressure block, and then rotating the threaded rod two to the abutment plate. By rotating the threaded rod two, the abutment plate can be pushed towards the photovoltaic panel, and then the abutment plate can be used to clamp the side wall of the photovoltaic panel, thereby further improving the stability of the photovoltaic panel placement.

[0017] A further improvement to the technical solution of this utility model is that the pressure block is set in an inverted V-shape.

[0018] Using the above technical solution, by setting the edge pressing component to an inverted V-shape, the photovoltaic panels placed on both sides of the upper part of the M-shaped water channel can be pressed and limited simultaneously using the edge pressing component.

[0019] A further improvement to the technical solution of this utility model is that the second slider is set to a T-shape.

[0020] By adopting the above technical solution, the contact area between the second slider and the inner cavity of the groove is increased by setting the second slider as a T-shape, thereby improving the stability of the second slider during movement.

[0021] A further improvement of this utility model is that both the pressing block and the abutment are made of rubber material.

[0022] In the above technical solution, since both the pressure block and the abutment are made of rubber, and rubber has good elasticity and cushioning properties, when the pressure block and the abutment respectively limit and fix the photovoltaic panel, the rubber can absorb part of the clamping force, avoiding direct hard squeezing of the photovoltaic panel by the edge pressing component, thereby protecting the photovoltaic panel from damage. Moreover, the elasticity of the rubber material allows it to better adapt to the surface shape of the photovoltaic panel, ensuring close contact between the edge pressing component and the photovoltaic panel, thereby helping to improve the stability of clamping and preventing displacement or detachment of the photovoltaic panel during installation.

[0023] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0024] 1. This utility model provides a photovoltaic roof waterproofing structure using concealed fasteners and clamps. By rotating the threaded rod, the slider can be raised and lowered above the connecting block, which in turn raises and lowers the connecting block. The upper end of the connecting block is then brought into contact with the lower end of the M-shaped water channel. The M-shaped water channel is then fixedly connected to the connecting block by self-tapping screws, thus fixing the position of the M-shaped water channel. This allows the connecting block to be used with purlins of different heights, thereby improving the practicality and versatility of the device.

[0025] 2. This utility model provides a photovoltaic roof waterproofing structure using concealed fasteners and clamps. The base is fixedly connected to the connecting block three by bolts, thereby fixing the position of the base in the inner cavity of the M-shaped water channel. The threaded rod three is rotatably connected to the base, and then the threaded rod three is threadedly connected to the pressing edge assembly. By rotating the threaded rod three, the pressing edge assembly can be driven to rise and fall, thereby driving the pressing edge assembly to fix photovoltaic panels of different sizes on the M-shaped water channel, thus improving the practicality and universality of the device.

By providing a purlin 1, the M-shaped water channel 3 can be supported by the purlin 1. By operating the threaded rod 24 to rotate, the slider 221 can be driven to rise and fall above the connecting block 21, thereby driving the connecting block 22 to rise and fall, so that the upper end of the connecting block 22 contacts the lower end of the M-shaped water channel 3. Then, the M-shaped water channel 3 and the connecting block 22 are fixedly connected by self-tapping screws, thereby fixing the position of the M-shaped water channel 3. The connecting block 21 can be adapted to purlins 1 of different heights. By fixing the connecting block 3 23 to one side of the connecting block 22, the pressure plate assembly 4 and the connecting block 3 23 can be fixedly connected together by self-tapping screws.

[0042] In this embodiment, when it is necessary to fix the photovoltaic panel on the roof, firstly, an M-shaped water channel 3 is laid on the purlin 1, and then the connecting block 21 is fitted under the purlin 1 and placed on the outside of the purlin 1, so that the purlin 1 is located in the inner cavity of the connecting block 21, and the lower end of the purlin 1 contacts the inner wall of the connecting block 21. Then, the worker holds the handle 241 and drives the threaded rod 24 to rotate, which drives the slider 221 to move upward on the upper part of the connecting block 21, which will drive the connecting block 22 to move upward together. When the upper end of the connecting block 22 contacts the lower end of the M-shaped water channel 3, the M-shaped water channel 3 and the connecting block 22 are then connected together by self-tapping screws.

[0043] Example 3

[0044] like Figure 6 , Figure 7 and Figure 8 As shown, based on Embodiment 2, this utility model provides a technical solution: Preferably, the pressure plate assembly 4 includes a base 42, which is fixedly connected to the connecting block 23 by bolts. A buffer pad 44 is symmetrically fixedly connected to the upper part of the base 42. A pressure edge assembly 41 is fixedly connected to the upper ends of the two buffer pads 44.

The pressure block 411 is shaped like an inverted "V", and the slider 414 is shaped like a "T". Both the pressure block 411 and the stop plate 413 are made of rubber material.

[0045] In this embodiment, the pressure plate assembly 4 is then placed in the middle inner cavity of the M-shaped water channel 3. The base 42, the M-shaped water channel 3, and the connecting block 23 are then connected together with self-tapping screws to fix the position of the pressure plate assembly 4 in the middle inner cavity of the M-shaped water channel 3. Then, by rotating the threaded rod 43, the pressing edge assembly 41 is moved upward. The operator then places the photovoltaic panel on the upper part of the M-shaped water channel 3. By rotating the threaded rod 43, the pressing edge assembly 41 is moved towards the photovoltaic panel. The pressing block 411 is used to press and limit the upper part of the edge of the photovoltaic panel.

Then, the worker holds the handle 241 and drives the threaded rod 24 to rotate, which drives the slider 221 to move upward on the upper part of the connecting block 21, which will drive the connecting block 22 to move upward together. When the upper end of the connecting block 22 contacts the lower end of the M-shaped water channel 3, the M-shaped water channel 3 and the connecting block 22 are then connected together by self-tapping screws.

[0048] Next, the pressure plate assembly 4 is placed in the middle inner cavity of the M-shaped water guide channel 3. Then, the base 42, the M-shaped water guide channel 3, and the connecting block 23 are connected together with self-tapping screws to fix the position of the pressure plate assembly 4 in the middle inner cavity of the M-shaped water guide channel 3. Then, by rotating the threaded rod 43, the pressing edge assembly 41 is moved upward. Then, the operator places the photovoltaic panel on the upper part of the M-shaped water guide channel 3. Then, by rotating the threaded rod 43, the pressing edge assembly 41 is moved towards the photovoltaic panel. The pressing block 411 is used to press and limit the upper part of the edge of the photovoltaic panel. Then, by rotating the threaded rod 412, the abutment 413 is pushed towards the photovoltaic panel. Then, the slider 414 is moved in the inner cavity of the groove 415. Then, the abutment 413 is used to clamp and limit the side wall of the photovoltaic panel.
