Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic roof installation systems, and in particular is a BIPV waterproof photovoltaic roof installation system. Background Art

[0002] Photovoltaic roof installation system refers to the photovoltaic system installed on the roof, which is divided into BAPV and BIPV according to the installation method. Among them, BAPV is to install the solar photovoltaic power generation system on the existing building through steel structure or aluminum alloy bracket, also known as "installation type" solar photovoltaic building. The defect of this technology is that the color steel tile roof of the steel structure factory building generally has a service life of about 10 years, which is easy to cause leakage due to rust corrosion and strength deterioration, and waterproofing is also relatively difficult. The design life of the photovoltaic power generation system is required to be 25 years, so the color steel tile must be replaced during operation, the maintenance cost is high, and a lot of resources are wasted. BIPV is a solar photovoltaic power generation system that is designed, constructed and installed at the same time as the building and forms a perfect combination with the building. It is also called "construction type" and "building material type" solar photovoltaic building. As part of the external structure of the building, it has both power generation function and the function of building components and building materials. It can even enhance the beauty of the building and form a perfect unity with the building.

[0003] However, the traditional BIPV photovoltaic roof installation system faces many challenges in practical application. On the one hand, it is often difficult to balance the waterproof performance of the roof and the stability of the photovoltaic module, resulting in frequent problems such as roof leakage and loose photovoltaic modules, which affects the long-term operation and reliability of the system. On the other hand, the difficulty and high cost of construction have also become important factors restricting the large-scale application of BIPV technology. Summary of the invention

[0004] In order to solve the problems raised by the above background technology, the present invention proposes a BIPV waterproof photovoltaic roof installation system.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A concrete base is laid on the roof, a waterproof membrane is arranged above the concrete base, a waterproof coating is laid between the concrete base and the waterproof membrane, a photovoltaic keel is arranged above the waterproof membrane, and a plurality of photovoltaic modules are arranged on the photovoltaic keel.

[0008] As a further preferred embodiment of the technical solution: a waterproof component is provided in the gap between the photovoltaic components;

[0009] The waterproof component includes a seal, and fixed plates are arranged on both sides of the seal. A pressure plate is rotatably connected to each of the fixed plates, and a spring is arranged between the pressure plate and the seal, and No. 2 rubber pads are arranged at the lower ends of the two pressure plates.

[0010] As a further preferred embodiment of the present technical solution: a slide groove is provided on the sealing member, a slider is slidably connected inside the slide groove, a threaded sleeve is fixedly connected to the slider, two symmetrically arranged No. 1 hinged seats are provided on the threaded sleeve, each of the No. 1 hinged seats is hinged with a connecting rod, and one end of the connecting rod away from the No. 1 hinged seat is hinged to a No. 1 rubber pad arranged on the pressure plate.

[0011] As a further preferred embodiment of the present technical solution: the waterproof component further comprises a threaded bolt threadedly connected to the bottom surface of the seal, and the threaded bolt is threadedly connected to the threaded sleeve.

[0012] As a further preferred embodiment of the present technical solution: a connecting plate is provided on the sealing member, and the cross section of the connecting plate is H-shaped.

[0013] As a further preferred embodiment of the present technical solution: the waterproof component also includes a drainage groove arranged on the top of the sealing member, and the drainage groove is arranged in a V shape.

[0014] As a further preferred embodiment of the technical solution: the interior of the sealing member is hollow, and a sealing slide plate is slidably connected to the sealing member.

[0015] As a further preferred embodiment of the present technical solution: the concrete base layer includes a cast-in-place layer, a thermal insulation layer and a leveling layer, and the thermal insulation layer is arranged above the cast-in-place layer, and the leveling layer is arranged above the thermal insulation layer.

[0016] As a further preferred embodiment of the present technical solution: a photovoltaic bracket is arranged below the photovoltaic keel for fastening and fixing the photovoltaic keel, and a plurality of photovoltaic brackets are arranged, and each photovoltaic bracket is fixed to the concrete base by an expansion bolt.

[0017] As a further preferred embodiment of the present technical solution: the bottom of the photovoltaic bracket penetrates into the cast-in-place layer, which can enhance the stability of the photovoltaic keel, and a waterproof rubber pad is arranged between the photovoltaic bracket and the leveling layer.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, through the use of the base layer, the main waterproof layer and the matching waterproof components, the three layers work together for waterproofing, combined with a stable supporting keel and an elastic sealing setting, the roof waterproofing performance is improved and the photovoltaic components are reliably fixed. At the same time, the modular rapid installation process significantly reduces the construction cost and difficulty, ensures the long-term operation of the system and promotes large-scale application.

[0020] 2. In the present invention, the seal, the pressure plate, the No. 2 rubber pad, the No. 1 rubber pad and the drainage groove form an all-round preliminary waterproof layer. The seal and the sealing slide plate fit tightly with the side wall of the photovoltaic module, and the pressure plate and the rubber pad seal the upper and lower frames of the photovoltaic module, which effectively prevents the infiltration of rainwater. At the same time, the drainage groove can guide most of the rainwater away, greatly reducing the risk of rainwater infiltration, thereby ensuring the long-term waterproof effect of the roof.

[0021] 3. In the present invention, through the cooperation of the connecting plate and the No. 1 rubber pad, not only an additional waterproof layer is formed, but also the edges of the photovoltaic modules are clamped together with the seal, reducing the risk of loosening of the photovoltaic modules and enlarged gaps due to the influence of the external environment (such as strong winds, crustal movement, etc.). This clamping effect enhances the structural stability of the photovoltaic roof, extends its service life, and reduces maintenance costs.

[0022] 4. In the present invention, by injecting filling liquid into the interior of the seal, the sealing slide plate is closely fitted to the side wall of the photovoltaic module, so that the system can adapt to the gaps between photovoltaic modules of different sizes, solve the problem of uneven gaps caused by manual installation errors, and improve the flexibility and adaptability of installation.

[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1-Figure 7 The present application provides a BIPV waterproof photovoltaic roof installation system, including a concrete base 1, which is laid on the roof. The thickness of the concrete base 1 is 15mm-25mm, and the surface flatness error is not more than ±3mm through a mechanical finishing process. A waterproof membrane 3 is arranged above the concrete base 1. The waterproof membrane 3 is composed of two layers of high-strength polyethylene film with a layer of rubber asphalt blend sandwiched in the middle. The surface of the upper polyethylene film has a micro-convex structure, which can increase the friction with the upper structure. The surface of the lower polyethylene film is smooth and easy to lay. The waterproof membrane 3 is spliced ​​by a hot welding process, and the width of the welding seam is not less than 10mm to ensure the integrity and waterproof effect of the waterproof layer. A waterproof coating 2 is laid between the concrete base 1 and the waterproof membrane 3. A photovoltaic keel 5 is arranged above the waterproof membrane 3. The C-shaped support keel made of aluminum alloy is adopted. Its cross-sectional shape is designed as a C-shaped structure with reinforcing ribs, which can improve the bearing capacity and anti-deformation ability of the keel. A plurality of photovoltaic modules 6 are arranged on the photovoltaic keel 5.

[0034] In this embodiment, the concrete base layer 1 includes a cast-in-place layer 7, an insulation layer 8 and a leveling layer 9, and the insulation layer 8 is arranged above the cast-in-place layer 7, and the leveling layer 9 is arranged above the insulation layer 8. The cast-in-place layer 7 is the base layer, and the cast-in-place layer 7 and the leveling layer 9 are made of cement mortar, and waterproof reinforcing agent and fiber material can be added to the cement mortar. The waterproof reinforcing agent can improve the waterproof performance of the cement mortar, and the fiber material can enhance the crack resistance of the base treatment layer. The setting of the insulation layer 8 can improve the thermal insulation effect of the house, and the leveling layer 9 is smoothed mechanically or manually, without specific limitation, so that there will be no gaps in the waterproof membrane 3 thereon during the laying process.

[0035] In this embodiment, a photovoltaic bracket 4 is provided below the photovoltaic keel 5 for fastening and fixing the photovoltaic keel 5 , and a plurality of photovoltaic brackets 4 are provided, and each photovoltaic bracket 4 is fixed to the concrete base 1 by an expansion bolt 12 .

[0036] In this embodiment, the bottom of the photovoltaic bracket 4 penetrates into the cast-in-place layer 7, which can enhance the stability of the photovoltaic keel 5, and a waterproof rubber pad 11 is arranged between the photovoltaic bracket 4 and the leveling layer 9 to increase the sealing and waterproof performance.

[0037] Embodiment 2:

[0038] On the basis of Example 1, a waterproof component 13 is provided at the gap between the photovoltaic components 6, which is used to seal the gap between two adjacent photovoltaic panels. The photovoltaic components 6 and the waterproof component 13 are standard modules prefabricated in the factory and then transported to the construction site for assembly. The size of the standard module is optimized according to the roof size and transportation conditions. The waterproof component 13 includes a seal 131, and fixed plates 138 are provided on both sides of the seal 131. A pressure plate 139 is rotatably connected to each of the fixed plates 138, and a spring 1311 is provided between the pressure plate 139 and the seal 131, and a No. 2 rubber pad 1310 is provided at the lower end of the two pressure plates 139 to increase the friction with the upper frame of the photovoltaic component 6.

[0039] In this embodiment, a slide groove 1312 is provided on the sealing member 131, and a slider 1313 is slidably connected inside the slide groove 1312. A threaded sleeve 1314 is fixedly connected to the slider 1313, and two symmetrically arranged No. 1 hinged seats 1315 are provided on the threaded sleeve 1314. Each of the No. 1 hinged seats 1315 is hinged with a connecting rod 1316 for pushing the pressure plate 139 to rotate, and the No. 2 rubber pad 1310 on the pressure plate 139 is sealed and fitted with the upper surface of the frame of the photovoltaic component 6 to form a waterproof layer to prevent rainwater from seeping from the top of the photovoltaic component 6 to the bottom of the photovoltaic component 6. The end of the connecting rod 1316 away from the No. 1 hinged seat 1315 is hinged to the No. 2 hinged seat 1317 arranged on the pressure plate 139.

[0040] In this embodiment, the waterproof component 13 further includes a threaded bolt 133 threadedly connected to the bottom surface of the seal 131 , and the threaded bolt 133 is threadedly connected to the threaded sleeve 1314 for driving the threaded sleeve 1314 to move up and down to realize the rotation of the connecting rod 1316 .

[0041] In this embodiment, a connecting plate 136 is provided on the sealing member 131, and a No. 1 rubber pad 137 is provided on the upper surface of the connecting plate 136. The connecting plate 136 is used to form an extrusion with the sealing member 131 to be fixed between the two photovoltaic modules 6. The No. 1 rubber pad 137 fits with the edge of the lower surface of the photovoltaic module 6, which can reduce the penetration pressure of rainwater and form a clamping effect, thereby reducing the long-term placement of the two photovoltaic modules 6 and the influence of the external environment, such as natural disasters such as strong winds and crustal movements, which may cause the photovoltaic modules 6 to loosen, thereby avoiding the problem of increasing the gap between the photovoltaic modules 6, and the cross-section of the connecting plate 136 is H-shaped.

[0042] In this embodiment, the waterproof component 13 also includes a drainage groove 132 disposed on the top of the seal 131, and the drainage groove 132 is arranged in a V-shape, which can divert most of the rainwater from above the gap between the two photovoltaic components 6, reducing the risk of rainwater infiltration.

[0043] Specifically, by clamping the waterproof component 13 in the gap between the two photovoltaic components 6, due to the tension of the spring 1311, the lower end of the second rubber pad 1310 is attached to the seal 131, and then the connecting plate 136 is sleeved on the threaded bolt 133, and the threaded bolt 133 is screwed in from the bottom of the seal 131. When the threaded bolt 133 hits the threaded sleeve 1314, the slider 1313 on the slider 1313 can slide downward inside the slide groove 1312, thereby driving the connecting rod 1316 to rotate, and the connecting rod 1316 opens the pressure plate 139, and the bottom end of the pressure plate 139 is pressed. The No. 2 rubber pad 1310 is pushed to fit the edge of the upper surface frame of the photovoltaic component 6, tightly sealed to form a waterproof layer to prevent the infiltration of snow water after melting. At the same time, the No. 1 rubber pad 137 on the connecting plate 136 is also squeezed and tightly sealed with the lower surface edge frame of the photovoltaic component 6, which can not only form a waterproof layer, but also cooperate with the seal 131 to clamp the edge of the photovoltaic component 6, which can reduce the risk of the gap between the two photovoltaic components 6 becoming larger due to the influence of the external environment. At the same time, the drainage groove 132 above the seal 131 can divert most of the rainwater, reducing the pressure of waterproofing below.

[0044] Embodiment three:

[0045] On the basis of the second embodiment, the interior of the sealing member 131 is hollow, and a sealing slide plate 134 is slidably connected to the sealing member 131, and the sealing slide plate 134 is made of rubber material, and is tightly sealed with the side wall of the photovoltaic component 6 to prevent rainwater from penetrating. The sealing member 131 is provided with a liquid filling port for injecting filling liquid. When the filling liquid is filled, the sealing slide plates 134 on both sides are squeezed to fit tightly with the side wall of the photovoltaic component 6, and a sealing arrangement is formed between the sealing slide plate 134 and the sealing member 131, and a sealing cover 135 is provided on the liquid filling port for sealing the liquid filling port.

[0046] Specifically, filling liquid is injected into the filling port on the seal 131 to squeeze the sealing slides 134 on both sides to fit tightly against the side walls of the photovoltaic component 6. This can adapt to the problem of different gap sizes between the two photovoltaic components 6 due to manual installation errors when installing the photovoltaic components 6, thereby improving the sealing and waterproofing effect.

[0047] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
