Description

Technical Field

[0001] The present invention relates to the field of building technology, in particular to a photovoltaic panel roof assembly device with both support and drainage functions. Background Art

[0002] With the continuous advancement of modern science and technology, architectural design concepts are constantly evolving and innovating, with green, energy-saving, and low-carbon designs becoming increasingly mainstream. Solar energy has long been considered a clean alternative to existing mineral-based energy sources, and photovoltaic power generation is increasingly widespread in my country. Because photovoltaic panels are modularly manufactured in factories and assembled on-site, drainage measures between panels are particularly important. Conventional photovoltaic modules are waterproofed primarily by gluing, splicing, or welding, which may work in the short term but inevitably lead to cracking and leaking in the long term. From the perspective of improving the cost-effectiveness and durability of photovoltaic roof drainage systems, there is still significant room for improvement. Therefore, a photovoltaic panel roof assembly with both support and drainage functions is urgently needed to address these issues. Summary of the Invention

[0003] The purpose of the present invention is to provide a photovoltaic panel roof assembly device with both support and drainage functions to solve the problems raised in the above background technology.

[0004] The technical solution of the present invention is: a photovoltaic panel roof assembly device with both support and drainage functions, including a roof main purlin, and also including;

[0005] An M-shaped support steel frame is fixed to the top outer wall of the main purlin of the roof by bolts. The top outer wall of the M-shaped support steel frame is clamped with equidistantly distributed clamping brackets, and the top outer wall of the clamping bracket is provided with a limiting groove;

[0006] The photovoltaic panel body is arranged above the clamping bracket;

[0007] The fixing mechanism is used to connect and fix the photovoltaic panel body and the clamping bracket.

[0008] Preferably, the fixing mechanism comprises a limiting protrusion sliding on the inner wall of the limiting groove, and a pressure plate is installed on the outer wall of the top of the limiting protrusion.

[0009] Preferably, trapezoidal rubber blocks are installed on both sides of the outer wall of the bottom of the pressure plate, and the outer wall of the bottom of the clamping bracket is connected to a fixing bolt through threaded rotation.

[0010] Preferably, connecting grooves are provided on both sides of the outer wall at the top of the clamping bracket, and an inserting plate is hingedly connected to the inner wall of one side of the connecting groove.

[0011] Preferably, a rubber sheet is slidably connected to the inner wall of the inserting plate, and a locking bolt is rotatably connected to the outer wall of the top of the inserting plate through a thread.

[0012] Preferably, a buffer spring is installed on the outer wall of the bottom of the rubber sheet, and the other end of the buffer spring is fixedly connected to the inner wall of the corresponding connecting groove.

[0013] Preferably, the M-shaped supporting steel frame and the main roof purlin are fixed by a first screw rod, and the M-shaped supporting steel frame and the clamping bracket are fixed by a second screw rod.

[0014] The present invention provides a photovoltaic panel roof assembly device with both support and drainage functions through improvements. Compared with the prior art, it has the following improvements and advantages:

[0015] Firstly, the present invention arranges an M-shaped supporting steel frame in the gap between the photovoltaic panels, ensuring that the M-shaped supporting steel frame serves as the secondary purlin of the roof while also having the function of roof drainage, thus forming an organized drainage function of the photovoltaic panel roof and greatly improving the overall durability and applicability;

[0016] Second, the present invention connects the photovoltaic panel body and the clamping bracket through a fixing mechanism, and the clamping bracket is connected to the side of the M-shaped support steel frame through a second screw, thereby avoiding the leakage of rainwater through the bolt holes and improving the waterproof effect;

[0017] Third: The present invention provides a rubber sheet, an insert plate and a buffer spring on the clamping bracket.

[0024] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] The present invention provides a photovoltaic panel roof assembly device with both support and drainage functions through improvement. The technical solution of the present invention is:

[0026] like Figure 1-Figure 3 As shown, a photovoltaic panel roof assembly device with both support and drainage functions includes a roof main purlin 1 and further includes;

[0027] The M-shaped support steel frame 4 is fixed to the top outer wall of the main roof purlin 1 by bolts. The top outer wall of the M-shaped support steel frame 4 is clamped with equidistantly distributed clamping brackets 5, and the top outer wall of the clamping bracket 5 is provided with a limiting groove 8;

[0028] The photovoltaic panel body 2 is arranged above the clamping bracket 5;

[0029] The fixing mechanism 3 is used to connect and fix the photovoltaic panel body 2 and the clamping bracket 5.

[0030] Furthermore, the fixing mechanism 3 includes a limiting protrusion 302 sliding on the inner wall of the limiting groove 8 , and a pressing plate 301 is installed on the outer wall of the top of the limiting protrusion 302 .

[0031] Furthermore, trapezoidal rubber blocks 304 are installed on both sides of the bottom outer wall of the pressure plate 301, and the bottom outer wall of the clip bracket 5 is connected to the fixing bolts 303 by threaded rotation. Due to the trapezoidal rubber blocks 304 arranged on both sides of the bottom of the pressure plate 301, the seal between the pressure plate 301 and the photovoltaic panel body 2 can be made tighter to prevent water leakage.

[0032] Furthermore, connecting grooves 9 are provided on both sides of the outer wall of the top of the clamping bracket 5 , and an inserting plate 7 is hinged to the inner wall of one side of the connecting groove 9 .

[0033] Furthermore, the inner wall of the plug board 7 is slidably connected to a rubber sheet 6, and the top outer wall of the plug board 7 is connected to a locking bolt by a threaded rotation. A cut is provided at one end of the rubber sheet 6, which can increase the contact area between the rubber sheet 6 and the bottom outer wall of the photovoltaic panel body 2, further improving the sealing effect.

[0034] Furthermore, a buffer spring 10 is installed on the bottom outer wall of the rubber sheet 6, and the other end of the buffer spring 10 is fixedly connected to the inner wall of the corresponding connecting groove 9. The plug plate 7 moves upward under the action of the buffer spring 10, so that the rubber sheet 6 is close to the bottom outer wall of the photovoltaic panel body 2, preventing rainwater from entering the outer wall of the main purlin 1 of the roof, and being discharged to the outside through the water flow channel formed at the bottom of the M-shaped support steel frame 4.

[0035] Furthermore, the M-shaped supporting steel frame 4 and the main roof purlin 1 are fixed by a first screw, and the M-shaped supporting steel frame 4 and the clamping bracket 5 are fixed by a second screw. The connection between the M-shaped supporting steel frame 4 and the main roof purlin 1 is spliced with glue, adhesive strips or welding.

[0036] Working principle: When in use, multiple M-shaped support steel frames 4 are fixed to the top outer wall of the roof main purlin 1 through the first screw, multiple clamping brackets 5 are placed on the M-shaped support steel frame 4 and fixed through the second bolt, and the photovoltaic panel body 2 is placed on the clamping bracket 5. The protrusion on the top of the clamping bracket 5 can limit the photovoltaic panel body 2 on both sides, and the limiting protrusion 302 is inserted into the limiting groove 8 on the M-shaped support steel frame 4. At this time, the pressure plate 301 on the limiting protrusion 302 can limit the photovoltaic panel body 2 on both sides of the bottom. The extrusion limiter prevents it from loosening during operation. Due to the trapezoidal rubber blocks 304 set on both sides of the bottom of the pressure plate 301, the seal between the pressure plate 301 and the photovoltaic panel body 2 can be made tighter to prevent water leakage. Then the rubber sheet 6 is inserted into the plug plate 7 and fixed with a locking bolt. The plug plate 7 moves upward under the action of the buffer spring 10, so that the rubber sheet 6 is close to the bottom outer wall of the photovoltaic panel body 2, preventing rainwater from entering the outer wall of the main purlin 1 of the roof, and being discharged to the outside through the water flow channel formed at the bottom of the M-shaped support steel frame 4.
